Abstract

Can a small state preserve and even strengthen sovereign agency when its economy, security, and foreign trade are deeply embedded in systems created by larger actors? A comparison of Paraguay and Luxembourg shows that integration in itself does not amount to a loss of sovereignty. What matters decisively is the architecture of embeddedness: whether the state has access to multiple external channels, participates in making common rules, can limit the depth of dependence, and retains the capacity to revise decisions without disrupting vital functions.

According to the sovereign agency indices provided, Paraguay scores 329.8 points out of 700, while Luxembourg scores 558.5. The gap is 228.7 points. Luxembourg outperforms Paraguay across all seven dimensions, especially the economic, political, technological, informational, and cognitive dimensions. Yet both countries are small, landlocked, and dependent on cross-border markets, transport networks, and the rules of regional organizations. The difference therefore cannot be explained by external dependence alone; it is related to the way dependence is institutionalized.

Paraguay is embedded in a South American architecture in which Brazil and Argentina function as the principal external centers. They are simultaneously markets, transit states, Mercosur partners, and co-owners of critically important hydroelectric facilities. Formal equality under interstate treaties coexists with major asymmetries in economic scale and bargaining capacity. Luxembourg, by contrast, has transformed its small size into institutional specialization: it operates within the European Union, the euro area, Benelux, and NATO, hosts European institutions, has developed a cross-border financial center, and participates in the collective production of rules.

The article’s central argument is that an external center constrains sovereign agency not when a state is deeply integrated, but when access to markets, infrastructure, security, or information is organized through a small number of channels that are difficult to replace and whose terms the state cannot influence. The strategic autonomy of a small state arises not from distancing itself from the external environment, but from the capacity to choose among channels, combine several institutional levels, set boundaries on participation, and make commitments politically and technically reversible.

Research Puzzle

Paraguay and Luxembourg belong to different regions, historical trajectories, and institutional systems. Yet they share several structural similarities that make comparison analytically productive. Both states are landlocked; both depend substantially on their neighbors; both use integration to overcome the limitations of a small domestic market; and both participate in collective decision-making regimes in which material capabilities are distributed highly unevenly.

Paraguay depends on the Paraguay–Paraná river system, access through neighboring territory to Atlantic ports, the markets of Brazil and Argentina, Mercosur, and the bilateral management of the Itaipu and Yacyretá hydroelectric plants. Rivers carry about 92% of the country’s export freight and 79% of its import freight, making the waterway both a resource of integration and a critical channel of dependence. Decisions by neighboring states on fees, dredging, navigation, and port procedures directly affect the Paraguayan economy.

Luxembourg likewise depends on an external environment, but its dependence is institutionally distributed. The EU single market, the euro, European law, cross-border labor, global capital, and NATO guarantees are conditions of the country’s functioning. The financial sector accounts for roughly one quarter of GDP and about one tenth of employment; investment-fund assets are many times larger than the national economy, while most banking assets are held by international groups.

The research puzzle is therefore as follows: why does deep embeddedness in an external architecture in one case preserve high sensitivity to decisions by larger neighbors, while in another it becomes a source of disproportionately large political and economic influence?

Answering this question requires distinguishing the number of external ties from the quality of control over them. A state may have many trading partners but only one irreplaceable route. It may formally possess a veto yet lack the information and coalitions needed to use it effectively. Conversely, transferring some competences to a supranational level may increase rather than reduce a small state’s practical capacity to influence its external environment.

Theoretical Framework

Sovereign agency is understood here not as freedom from all external constraints, but as a state’s capacity to define its own objectives, choose among available means, participate in rule-setting, limit unacceptable dependencies, and change course without disproportionate costs. This understanding distinguishes legal sovereignty from strategic capacity for action.

Legal sovereignty asks who formally possesses the right to decide. Sovereign agency asks a different question: can the state actually exercise that right? If a state’s exports can be halted by a neighboring country’s transit decision, formal independence does not guarantee practical choice. If, by contrast, a state transfers some powers to an organization but gains a stable market, judicial protection, coalition partners, and a seat at the negotiating table, the range of available choices may expand.

An external center is understood as an actor or institutional node through which a disproportionate share of critical functions passes: an export market, transit, currency, security, capital, digital infrastructure, or rule production. An external center need not be a state. It may be a neighboring economy, a regional bloc, a financial jurisdiction, a technology platform, or a network of international institutions.

The paradox arises because integration simultaneously creates constraints and resources. It reduces the freedom of unilateral action, but lowers transaction costs, opens markets, provides predictability, and allows a small state to draw on collective power. Delegation of authority and loss of agency therefore do not automatically coincide.

For small states, autonomy is often relational rather than autarkic. It is created through partner diversification, institutional layering, specialization, reputation, coalitions, and legal guarantees. The state does not withdraw from the external system; instead, it seeks to ensure that no single channel can be used as an irreplaceable instrument of coercion.

Method

The comparison follows a most-different-systems logic. Paraguay and Luxembourg are similar in their small scale and landlocked geography, but differ radically in income, institutional environment, type of regional integration, and capacity to influence common rules. This makes it possible to distinguish structural vulnerability from the architecture through which it is managed.

All seven mechanisms are treated as a sequence:

1. Diagnosis of the external center: identifying critical markets, routes, institutions, infrastructures, and rule providers.
2. DAS: assessing the diversity of external supports and the degree to which they are correlated.
3. AS: the capacity to create alternatives and reconfigure external relationships.
4. BS: the capacity to set boundaries on participation—that is, to determine which competences may be shared and which must remain under national control.
5. RS: the reversibility of decisions that increase dependence, including the cost of changing a partner, route, institutional regime, or technological standard.
6. Influence over rules: moving from adaptation to external norms toward participation in their design and coalition-based advancement of interests.
7. Reproduction: embedding diversification, alternatives, boundaries, and reversibility in laws, organizations, professional capabilities, and durable political coalitions.

Particular attention is given to the DAS + AS + BS + RS nexus. Analytically, these mechanisms answer four different questions. DAS shows how numerous and independent external supports are. AS assesses whether the actor can create a new channel rather than merely choose among existing ones. BS captures the state’s right to determine where joint governance ends and inalienable national competence begins. RS measures the cost of exit or reconfiguration.

The mechanisms are cumulative. Multiple channels without the ability to switch among them do not create autonomy. Switching without national boundaries of control merely allows one dependence to be replaced by another. Boundaries without reversibility may prove declaratory if technical and contractual decisions already taken cannot be changed.

Index Profile

Paraguay scores 47.1% of the notional maximum, while Luxembourg scores 79.8%. The average gap per dimension is 32.7 points. The largest difference appears in the economic dimension—56.4 points—followed by the political dimension at 45.9 and the technological dimension at 43.8. The smallest gap is in the military dimension, at 5.7 points.

The distribution matters for interpretation. Luxembourg does not possess a large territory, population, or armed forces. Its advantage is generated where integration can be converted into agency: access to capital, institutional participation, technology, information, and specialized knowledge. The military dimension reveals the limit of this model: collective guarantees increase security but do not turn the country into an autonomous military power.

Paraguay’s profile is not uniformly low. Its cultural score of 73.6 is substantially higher than its economic and technological scores. This means that the country possesses a social and identity-based foundation for independent policy, but is less successful at converting it into material alternatives, technological capabilities, and control over external channels.

The overall gap of 228.7 points should not be interpreted as a direct measure of formal independence. It captures a difference in the practical capacity to use integration. Luxembourg is stronger not because it depends less on the external environment, but because its dependence is more diversified, institutionally protected, and partly converted into influence.

Paraguay’s Architecture

Paraguay’s embeddedness is strongly geographic. The country lies between larger economies and has no direct access to the sea. Its export model rests on agricultural commodities, hydropower, and river logistics. The Paraguay and Paraná Rivers form the transport backbone through which most trade passes.

This architecture creates a dual dependence. Exports depend not only on external demand but also on the physical and regulatory conditions of transit. Drought, low water levels, insufficient dredging, fees imposed by neighboring states, and border delays all affect the same chain. The World Bank has estimated the additional logistics costs of drought across a broad range, while waterborne logistics itself accounts for a significant share of GDP in normal years.

The second node is hydropower. Itaipu is a jointly owned facility with Brazil in which each side is entitled to half of the output; financial terms and arrangements for selling electricity are governed by the bilateral treaty and its Annex. Formal parity of ownership does not eliminate asymmetry: the Brazilian market is far larger, while Paraguay has historically consumed only part of its share and depended on the terms governing the sale of the surplus.

The third node is Mercosur. The bloc is the country’s principal external economic and foreign-policy framework, and a substantial share of Paraguayan trade is conducted with its members. Because decisions are taken by consensus, Paraguay formally has the right to block major initiatives. The actual effectiveness of that veto, however, depends on its capacity to withstand economic and political pressure from larger partners.

The fourth node is macroeconomic and financial governance. Paraguay has demonstrated sustained growth, manageable inflation, and progress in reform; the IMF has noted satisfactory program performance and improved access to international financing. This creates an additional channel of agency because a more resilient state is less dependent on emergency support from a single external center.

Luxembourg’s Architecture

Luxembourg is embedded in a much denser institutional system. It is a member of the EU, the euro area, Benelux, and NATO, and it hosts European institutions. The transfer of some sovereign powers to the EU is accompanied by Luxembourg’s direct participation in the European Council, the Council of the EU, the European Commission, the Court of Justice of the European Union, and other bodies.

European integration gives Luxembourg access to the single market, monetary stability, legal guarantees, and the capacity to participate in regulating a space far larger than its domestic economy. At the same time, the EU political system combines different principles of representation. Qualified majority voting applies in many areas, limiting the individual weight of a small country, while taxation, foreign policy, and several other sensitive fields retain unanimity.

Luxembourg’s economic specialization is built on cross-border financial services. The financial sector accounts for roughly one quarter of GDP and 10% of employment; investment funds manage assets many times larger than national GDP, and the banking sector consists predominantly of foreign groups. This makes the country sensitive to global markets and external regulation, while simultaneously turning it into a node on which other actors depend.

Luxembourg does not merely gain access to external capital. It provides the legal, administrative, and financial infrastructure for its cross-border movement. External dependence is therefore reciprocal: global investors depend on Luxembourg’s predictability and specialized ecosystem, while the country depends on investor confidence and continued access to the European market.

In security, Luxembourg deliberately relies on NATO and European mechanisms. National defense policy explicitly combines collective solidarity with the principle of decision-making autonomy and control over the life cycle of military capabilities. Partnerships with Belgium, the Netherlands, France, Germany, the United States, and multilateral agencies are treated as necessary because of structural constraints.

Diagnosing the Center

Paraguay

Paraguay has several external centers, but they are closely correlated. Brazil is a major market, source of investment, Itaipu partner, and important Mercosur member. Argentina simultaneously serves as a transit state, market, Yacyretá partner, and key actor in the river system. If relations with either neighbor deteriorate, several functions are affected at once.

This correlation is precisely what distinguishes partner diversification from diversification of dependence. Having two large neighbors does not guarantee two interchangeable channels. Routes pass through a common river system, markets are governed by regional agreements, and energy assets are tied to specific bilateral partners.

The history of Mercosur illustrates the limits of formal equality. Consensus gives every member a veto, but in 2012, after Paraguay’s temporary suspension, the remaining countries approved Venezuela’s accession, which Asunción had previously blocked. The episode demonstrates that a small state’s procedural right is vulnerable when other members can alter the conditions of its participation.

Luxembourg

Luxembourg has no single external center in the same form. Functions are distributed across the EU, the euro area, NATO, global financial markets, and bilateral partners. These systems overlap but do not fully coincide. Economic regulation operates primarily through the EU, monetary policy through the euro area, security through NATO and the EU, and investment flows through global markets.

Diversification does not eliminate systemic risk. The financial sector depends on global interest rates, asset values, cross-border regulation, and confidence. The OECD emphasizes that Luxembourg’s high degree of openness and large financial sector make it sensitive to global shocks. Yet a disruption in one channel does not necessarily paralyze all the others.

Institutional layering allows Luxembourg to maneuver among levels. It can advance its interests through Benelux, coalitions of small states, the Council of the EU, the Commission, the European Parliament, and professional networks. The external architecture is therefore not only a constraint but also a set of arenas for action.

DAS: External Supports

DAS assesses not the formal number of partners but the functional diversity of supports and their substitutability. Sovereign diversification exists when the loss of one channel does not simultaneously disable trade, finance, energy, security, and information.

Paraguay is expanding its external ties through Mercosur, bilateral diplomacy, international financial institutions, and the maquila regime. Yet critical material flows remain concentrated within the regional geography. The river system carries most freight, while agricultural and energy exports are oriented toward neighboring markets.

Paraguay has potential alternatives: Pacific corridors through Chile and Bolivia, road and rail routes, new markets for meat and soy, digital services, processing, and domestic use of low-cost hydropower. An alternative becomes sovereign, however, only once infrastructure, contractual access, commercial scale, and a durable procedure for its use are in place.

Luxembourg has a more multilayered system of supports. The EU single market provides economic scale; the euro area, a monetary framework; NATO, collective defense; global financial markets, capital; and European institutions, channels of influence. The country is developing fintech, sustainable finance, logistics, digital activities, and space-related sectors, thereby reducing dependence on traditional banking.

Luxembourg’s diversification also contains hidden correlation. Finance, international companies, cross-border employment, and tax revenues all depend on preserving the European regime of openness. A crisis of confidence in the financial model or a major EU regulatory restructuring could affect several apparently distinct channels at the same time.

Thus, Luxembourg’s DAS is higher because of institutional plurality, but it does not amount to complete independence. Paraguay’s DAS is constrained by geography and physical infrastructure, although hydropower, regional markets, and international programs provide a basis for further diversification.

AS: Creating Alternatives

AS differs from passive diversification. It indicates whether a state can create new options and use competition among them. A potential route is not an alternative if it is economically unviable or depends on the same point of control.

For Paraguay, the principal test of AS is whether hydropower can be transformed from an object of bilateral bargaining into a platform for industrialization. The ability to sell surplus electricity under more flexible rules or direct it toward domestic energy-intensive production could reduce dependence on a single buyer. Negotiations over Annex C to the Itaipu Treaty directly concern tariffs, financial terms, and options for marketing electricity.

The second test is transport. The country can reduce dependence on a single section of the waterway through reliable dredging, port modernization, road connections, and the development of alternative corridors. The World Bank regards improvements in road and river logistics as central to Paraguay’s competitiveness.

The third test is trade policy. Mercosur membership provides preferential access to the regional market but limits freedom to conclude individual agreements. Paraguay can expand alternatives through bloc-wide agreements and by developing exports that are less dependent on physical transit than agricultural commodities.

Luxembourg creates alternatives primarily through specialization. After the decline of steel, the country successively developed banking services, investment funds, insurance, logistics, satellite activities, and digital sectors. In 2025 it retained its status as a Strong Innovator, performing above the EU average.

Luxembourg’s AS is nevertheless constrained by shortages of scale, labor, and territory. The OECD points to the need to move from a growth model based on labor-force expansion toward one based on skills, innovation, and productivity. Alternatives must therefore generate not merely new sectoral brands, but independent productivity and a tax base.

BS: Boundaries of Participation

BS asks which functions a state is prepared to share with external institutions and which it regards as inalienable. The boundaries of sovereign participation need not coincide with maximum nationalization. Their purpose is to prevent loss of control over decisions on which critical functions depend.

For Paraguay, the key boundaries run through energy, transit, and trade regulation. Joint ownership of Itaipu is a rational response to the geography of the river and the scale of the project, but the state must retain the capacity to determine the domestic use of its share of electricity, obtain full information on costs, and participate in tariff-setting. The current review of Annex C shows that the boundary between joint management and national freedom remains subject to negotiation.

Within Mercosur, Paraguay retains formal control through the bloc’s intergovernmental character and consensus rule. Unlike the EU, Mercosur does not entail such deep delegation of powers to supranational bodies; decisions require state consent and subsequent domestic implementation. This protects legal boundaries but makes common rules less predictable and increases dependence on political relations.

Luxembourg has transferred substantially more competences to the EU. European law applies directly across a broad range of areas, and national discretion is constrained by common rules. Yet the boundaries of participation are embedded in treaties, judicial procedures, and voting regimes. Unanimity remains in sensitive areas, including taxation and foreign policy.

The Luxembourg model shows that BS can be exercised not by retaining every competence, but by controlling the procedure through which it is shared. If rules are defined in advance, the state is represented in decision-making bodies, enjoys judicial protection, and participates in treaty revision, shared competence remains politically manageable.

Luxembourg’s weak point is dependence on the preservation of the common architecture. National control over the financial model is constrained by EU rules, international tax standards, and transparency requirements. BS is therefore secured not by unilateral prohibition but by the capacity to shape the regulatory agenda before a rule is adopted.

RS: Reversibility

RS measures how costly it is for a state to revise decisions that have increased dependence. Full reversibility is impossible in international integration: infrastructure, law, business models, and professional skills create sunk costs. The relevant objective is therefore managed reversibility—the existence of a transition period, backup channel, legal procedure, and resources for adaptation.

Paraguay faces low physical reversibility. Geography cannot be changed, and the Paraguay–Paraná waterway cannot be rapidly replaced. Itaipu is likewise a site-specific asset permanently linked to Brazil. Autonomy must therefore be created not through exit but through changes in access rules, domestic electricity use, route redundancy, and stronger bargaining capacity.

Mercosur’s institutional reversibility is formally higher because the bloc remains intergovernmental. Yet the economic cost of distancing Paraguay from the common market of Brazil and Argentina would be high. Moreover, an individual state cannot freely conclude any trade agreement without affecting the common external tariff and the bloc’s commitments.

The legal and technical reversibility of Luxembourg’s deep European integration is also low. Exit from the euro area or the single market would impose extraordinarily high costs on the financial center. Within the system, however, internal reversibility is high: rules are revised, coalitions change, decisions can be challenged in court, and the national government participates in shaping new compromises.

This distinction is fundamental. Paraguay’s dependence is often reversible only through renewed negotiation with a specific larger neighbor. Luxembourg’s dependence is modified through a multilateral procedure in which no single large partner can unilaterally rewrite the entire regime. Qualified majority voting reduces Luxembourg’s individual veto but also protects it against unilateral dictates by any one state.

Influence over Rules

The capacity to participate in rule-setting transforms integration from an object of dependence into an instrument of agency. For small states, influence is generally based not on coercion but on expertise, reputation, mediation, coalitions, and control over niche functions.

Paraguay possesses formal instruments of influence. Mercosur decisions are taken by consensus, and the presidency rotates among full members. At Itaipu, the country is legally an equal participant. These mechanisms make it possible to block an unfavorable decision and elevate issues to the highest political level.

Paraguay’s influence, however, is often reactive. The state defends a tariff, its right to energy, transit conditions, or its position within Mercosur after a larger partner has introduced an initiative. A higher level of rule-shaping would require Paraguay to advance regional projects of its own: green-energy standards, a common logistics policy, digital corridors, mechanisms protecting smaller members, and coalitions with Uruguay and other medium-sized states.

Luxembourg operates in a more developed institutional environment. It is represented in the principal EU bodies, hosts several European institutions, and participates in the Council with equal representation by member states, although its weight under qualified majority voting is limited by population. The country’s influence has historically been associated with the quality of its representatives, political continuity, a reputation for mediation, and an orientation toward pan-European compromise.

Financial specialization provides an additional resource. Because Luxembourg is an important center for investment funds and cross-border financial services, its regulatory expertise is valuable in European negotiations. Yet this specialization can also be perceived by partners as the defense of narrow tax or financial interests, limiting its coalition capital.

Institutional Symmetry

A comparison of Mercosur and the EU shows that formal equality and practical autonomy do not always coincide. Mercosur retains strong intergovernmentalism: every state has a voice and the consensus rule, while supranational bodies remain relatively weak. This structure appears protective of sovereignty but does little to constrain the informal predominance of the largest economies.

The EU, by contrast, deeply constrains the unilateral freedom of its members. Much legislation is adopted by qualified majority, and a common court can enforce obligations. Yet these same institutions depersonalize the power of large states and guarantee smaller members access to procedure.

For Paraguay, the external system often takes the form of interstate bargaining in which material asymmetry remains direct. For Luxembourg, it is more often transformed into legal and bureaucratic procedure. Paraguay therefore formally delegates less sovereignty but may possess less practical agency; Luxembourg delegates more authority but gains more protected channels of influence.

This does not imply the unconditional superiority of supranationalism. If a common procedure systematically disregards the interests of small states, or if key decisions migrate to informal clubs of large countries, integration once again produces dependence. The decisive factor is the relationship between the depth of commitments and genuine access to their formation.

Seven Dimensions

Political

The 45.9-point gap reflects the difference between possessing a formal voice and converting it into durable influence. Paraguay has the consensus right in Mercosur and a parity position at Itaipu, but it interacts with much larger neighbors. Paraguay’s suspension from Mercosur in 2012 demonstrated the vulnerability of procedural protection in the face of a regional political coalition.

Luxembourg is embedded in a multilevel system in which its individual weight is limited but its representation is guaranteed. Unanimity remains in sensitive areas; elsewhere, the country operates through coalitions, expertise, and European institutions. Its high political score reflects the capacity to co-shape the environment rather than act outside it.

Economic

The 56.4-point gap is the largest. Paraguay’s economy depends on agricultural exports, hydropower, river transit, and neighboring markets. Drought and restrictions on the waterway can simultaneously reduce exports and raise transport costs.

Luxembourg depends even more heavily, in relative terms, on the financial sector and global capital. Financial services generate roughly one quarter of GDP, while fund assets amount to about 77 times GDP. Yet this dependence is embedded in a high-income, legally protected, globally diversified system in which Luxembourg itself provides critical infrastructure.

Technological

The 43.8-point gap points to Paraguay’s limited capacity to offset geography through technology. Customs digitalization, river monitoring, smart logistics, interconnectors, and energy-intensive industry could convert its hydropower advantage into new alternatives. At present, technological dependence is combined with infrastructure bottlenecks.

Luxembourg uses the European market and its financial base to develop fintech, digital services, logistics, and space-related specialization. In 2025, the country ranked among the EU’s Strong Innovators. At the same time, 2026 data point to weakening innovation finance and the need to accelerate digital adoption among small and medium-sized enterprises.

Informational

The 32.8-point gap concerns access to data and the capacity to shape interpretations of external rules. Paraguay depends on information about navigation, hydrology, regional markets, energy accounts, and decisions by neighboring administrations. If data are dispersed among binational organizations and foreign agencies, its bargaining position becomes reactive.

Luxembourg sits at the center of European regulatory and financial flows. Hosting EU institutions and international companies provides early access to rule-making agendas and specialized knowledge. Yet the openness of the financial system simultaneously creates demands for transparency, anti-money-laundering controls, and tax-information exchange.

Cultural

The 12-point gap is comparatively small. Paraguay has a strong national identity, a bilingual culture, and a historical memory of interaction with larger neighbors. This foundation supports aspirations to energy and foreign-policy sovereignty.

Luxembourg’s identity combines national distinctiveness with a European orientation. Multilingualism and cross-border openness function not as a dissolution of the state but as a specialized resource. Support for European and Atlantic integration has historically shown high political durability.

Cognitive

The 32.1-point gap reflects the capacity to understand a complex external system and formulate strategy within it. Paraguay needs expertise in energy law, river logistics, international trade, climate modeling, and digital infrastructure. A shortage of expertise increases dependence on partners’ data and projects.

Luxembourg has accumulated specialized knowledge in finance, European law, multilateral negotiations, and cross-border administration. Its model, however, requires continuous skills renewal. The OECD stresses the need for productivity growth, upskilling, and innovation-driven restructuring.

Military

The 5.7-point gap is the smallest because both states have limited independent defense capabilities. Paraguay cannot convert economic integration with its neighbors into a comprehensive guarantee against every form of pressure. Its security is closely tied to regional stability and diplomacy.

Luxembourg benefits from NATO’s collective protection but maintains only small national forces. Its defense strategy recognizes the need for partnerships and shared capabilities while establishing decision-making autonomy as a separate principle. A high level of security and autonomous national military capacity are therefore distinct indicators.

Mechanism Matrix

The matrix shows that the most important difference concerns not the depth of integration but the location of the point at which rules can be changed. In Paraguay’s case, it often lies in negotiations with a specific large neighbor. In Luxembourg’s case, it is distributed among formal institutions, coalitions, and judicial procedures.

Luxembourg cannot easily leave the external architecture, but it can continually recalibrate its position within it. Paraguay formally retains greater unilateral freedom, yet geography and critical infrastructure make some dependencies nearly irreversible. Exit capacity is therefore not the only measure of autonomy; the capacity to change a regime without exiting it is equally important.

Energy and Finance

Itaipu for Paraguay and the financial center for Luxembourg perform a similar structural function. Both are externally oriented nodes whose scale exceeds domestic demand. Both generate income and international significance, but tie the national economy to a larger system.

Paraguay owns half of Itaipu’s output, but use of the surplus depends on contractual relations with Brazil. Sovereign agency will increase if the energy creates several options: exports to different buyers, supply to domestic industry, production of new energy-intensive goods, and regional interconnectors. If the surplus remains tied to a single buyer and a single pricing regime, the resource does not translate into full optionality.

Luxembourg’s financial sector serves international clients and depends on foreign institutions, yet the country controls an important part of the legal and administrative infrastructure. Interdependence is deeper: relocating the entire ecosystem requires time, specialists, and regulatory reputation. This increases Luxembourg’s bargaining power.

Financial specialization nevertheless creates a risk of excessive concentration. The OECD notes the dependence of employment and tax revenues on cross-border financial operations. Luxembourg therefore needs to turn the financial center into a platform for new industries rather than treat high current income as sufficient evidence of autonomy.

Transport and Market

For Paraguay, transport autonomy is fundamental. Direct access to the sea cannot be created, but the cost of the geographic constraint can be reduced. The country has a large river fleet and a natural network, yet navigation depends on hydrology, dredging, ports, and neighbors’ rules. Border delays, fees, and inadequate infrastructure increase the cost of switching routes.

Strategy should distinguish redundancy from duplication. Building fully parallel infrastructure may be prohibitively expensive, but partial redundancy—alternative ports, dry ports, road connections, digital transit documents, insurance mechanisms, and minimum-access agreements—raises RS.

Luxembourg addresses the problem of a small domestic market through the EU single market. Its companies operate within a legal space of hundreds of millions of consumers, while financial services scale across borders. Integration thus becomes a condition of national specialization while distributing demand across many countries.

European regulation may constrain some of Luxembourg’s competitive advantages, but it protects the country against discriminatory barriers imposed by any particular neighbor. For a small state, a predictable common rule often provides more agency than formal freedom to negotiate separately with each large market.

Security

Paraguay and Luxembourg illustrate two approaches to the security of a small state. Paraguay relies on the absence of an immediate high-intensity interstate threat, regional diplomacy, and its own limited forces. Its principal risks also include transnational crime, border security, and the protection of critical infrastructure.

Luxembourg has abandoned the idea of independent full-spectrum defense and embedded itself in NATO. The collective system greatly increases its security, although the military index remains the weakest component of its overall profile. The country develops niche capabilities, including cyber and space-related capacities, and recognizes that partnerships are necessary for complex operations.

Collective defense does not eliminate the question of BS. A state must retain political control over the participation of its forces, data, procurement, and critical technologies. Luxembourg’s defense strategy explicitly includes decision-making autonomy and control over the capability life cycle.

For Paraguay, the implication is not mechanical accession to a military bloc but the creation of multilayered resilience: interoperable monitoring of borders and rivers, diversified training, national control over data, and the absence of a monopoly by any single external security provider.

Counterarguments

The first counterargument is that the difference is fully explained by wealth. Luxembourg is indeed far richer and has the resources for a professional bureaucracy, technology, and international presence. Yet wealth itself is connected to institutional strategy: access to the European market and the country’s transformation into a financial and regulatory hub were products of long-term political choices.

The second counterargument attributes the outcome exclusively to the quality of the regional organization. The EU is deeper and more formalized than Mercosur, providing smaller members with better protection. This explanation is important but not exhaustive. Luxembourg actively helped shape European integration and specialized in functions that increased its value to the system; Paraguay can likewise improve agency within a less supranational architecture through coalitions, infrastructure, and expertise.

The third counterargument holds that Luxembourg is not autonomous but merely enjoys the protection of larger states. In the military sphere this is partly true. Sovereign agency, however, does not require independent production of every function. The relevant question is whether dependence can be used coercively. Multilateral guarantees, distributed functions, and participation rights reduce that possibility compared with reliance on a single patron.

The fourth counterargument is that Paraguay possesses greater formal freedom because Mercosur lacks strong supranational authority. Yet formal freedom offers little help when physical logistics and markets are concentrated. Legal reversibility without a material alternative may remain symbolic.

The fifth counterargument concerns the sustainability of Luxembourg’s financial model. Global regulatory harmonization, tax changes, and market shocks may weaken the country’s competitive advantages. The OECD indeed points to concentration and the need for higher productivity and diversification. Luxembourg’s model is therefore successful, but not complete.

Testable Hypotheses

H1. Architecture-not-depth hypothesis. Deeper integration increases sovereign agency only when the state has formalized participation in the production of common rules; without such participation, greater depth increases dependence.

H2. Uncorrelated-supports hypothesis. DAS increases agency only when external channels are not controlled by a single actor and do not depend on a single physical or institutional node.

H3. Internal-reversibility hypothesis. A small state can compensate for a high cost of exit if the system provides accessible procedures for changing rules, judicial challenge, and coalition-based revision.

H4. Procedural-symmetry hypothesis. A formalized multilateral procedure protects a small state better than bilateral legal equality under conditions of major material asymmetry.

H5. Functional-irreplaceability hypothesis. A small state increases its influence when it becomes a provider of specialized infrastructure that is costly for partners to replace.

H6. Participation-boundaries hypothesis. Delegation of competences increases agency when the boundaries of delegation are clear, review procedures are institutionalized, and the state retains control over critical data and domestic implementation.

H7. Geographic-compensation hypothesis. For a landlocked state, technological, contractual, and infrastructure diversification has a greater effect on agency than simply increasing the number of trading partners.

H8. Conversion-node hypothesis. An export asset strengthens autonomy when it creates several domestic and external modes of use; tying it to a single buyer reduces its sovereign effect regardless of formal ownership.

H9. Coalition-scale hypothesis. A small state’s influence increases when it can align its position with the interests of other small and medium-sized participants before negotiations with the external center begin.

H10. Reproducible-specialization hypothesis. A niche strategy increases agency only when its advantages are embedded in human capital, law, infrastructure, and reputation rather than resting solely on temporary tax or price differentials.

Risks for Paraguay

Correlated dependence: markets, transit, energy, and regional politics are concentrated around Brazil and Argentina.

Physical irreversibility: the lack of a coastline and the critical role of two rivers constrain rapid logistical switching.

Climate risk: low water levels simultaneously reduce export volumes and increase transport costs.

Energy lock-in: the formal right to half of Itaipu’s electricity does not automatically provide freedom to commercialize it.

Reactive rule-making: the country often responds to decisions by the external center rather than advancing regional rules of its own.

Weak technological conversion: inexpensive electricity does not guarantee the creation of an industrial and digital base.

Institutional vulnerability: the consensus right can be weakened by political suspension procedures or informal pressure, as the 2012 crisis demonstrated.

Export concentration: agricultural specialization ties external resilience to climate and commodity prices.

Cost of alternatives: new corridors and industrial projects require major investment and a long time horizon.

Risks for Luxembourg

Financial concentration: the sector generates roughly one quarter of GDP and depends on cross-border operations.

Regulatory dependence: changes in EU rules and international taxation can rapidly alter comparative advantages.

Foreign ownership: domestically owned banks account for only a small share of banking assets.

Labor dependence: the economic model requires a continuous inflow of cross-border workers and skilled migrants.

Low external reversibility: withdrawal from the single market or the euro area would be extraordinarily costly.

Military limitations: collective guarantees do not create full autonomy of national forces.

Declining productivity: OECD and European assessments point to the need for innovation-driven diversification and renewal of the growth model.

Reputational risk: confidence in the financial jurisdiction is sensitive to transparency, tax competition, and compliance with international standards.

Systemic risk: global interest rates and fund outflows simultaneously affect the financial sector, the budget, and employment.

Recommendations for Paraguay

The first priority is to move from partner diversification to functional diversification. A new trade relationship has limited value if it uses the same waterway and depends on the same neighboring authorizations. The state needs a map of critical dependencies linking commodities, routes, ports, energy supply, financing, data, and law.

The second priority is to turn hydropower into AS. Paraguay’s Itaipu share should create several competing modes of use: domestic industry, exports on more flexible terms, regional contracts, computing infrastructure, and the production of low-carbon goods. New projects should be assessed according to whether they reduce dependence on a single buyer.

The third priority is to increase the RS of logistics. Full duplication of the waterway is impossible, but backup ports, road corridors, digital documentation, guaranteed transit regimes, hydrological monitoring, and insurance can reduce the cost of disruption. Priority investments should be selected not only for time savings under normal conditions but also for resilience during drought and political conflict.

The fourth priority is to develop a coalition strategy within Mercosur. Cooperation with Uruguay and issue-specific coalitions with other participants can transform an individual veto into a positive agenda: transit standards, rights of landlocked states, digital trade, green energy, and compensation for asymmetries.

The fifth priority is to professionalize negotiating functions. Energy, trade, and logistics teams should maintain permanent archives, their own analytical models, and interagency continuity. The bargaining position should not have to be recreated after every change of government.

The sixth priority is to establish BS for foreign investment. Critical data, energy dispatch, customs systems, hydrological monitoring, and infrastructure standards can be developed with foreign partners, but the state should retain access to source data, interoperability, and the right to change suppliers.

Recommendations for Luxembourg

The first priority is to preserve institutional diversification. The EU, the euro area, and NATO perform different functions, so foreign policy should not allow them to collapse into reliance on a single bilateral patron. Coalitions with Benelux, smaller EU states, and issue-specific partners should be formed before key negotiations.

The second priority is to convert financial specialization into technological alternatives. Fintech, sustainable finance, cybersecurity, digital infrastructure, and space services should generate independent productivity rather than merely serve the traditional financial sector. European assessments explicitly link the country’s resilience to innovation-driven diversification.

The third priority is to protect internal reversibility within the EU. Deep integration benefits Luxembourg when decisions can be revised through transparent procedures, courts, and coalitions. Protecting the rule of law and institutional balance is therefore an element of national strategy, not an abstract European value.

The fourth priority is to reduce the concentration of critical knowledge within foreign financial groups. National regulators, universities, and public analytical centers should retain their own risk models, data capabilities, and technological infrastructure.

The fifth priority is to preserve BS in defense cooperation. Joint procurement and specialization are rational for a small state, but they require control over operational data, cybersecurity, capability availability in a crisis, and system life cycles. This principle is already embedded in national defense policy.

The sixth priority is to limit the reputational dependence of the financial center. Transparency and predictable compliance with common standards should be treated as strategic assets, because trust is one of the principal forms of interdependence that generate Luxembourg’s influence.

Conclusion

The comparison of Paraguay and Luxembourg challenges the idea of a linear relationship between integration and the loss of sovereignty. Both states depend deeply on external systems. Paraguay, however, more often faces dependencies concentrated around specific neighbors, physical routes, and bilateral assets, whereas Luxembourg distributes critical functions across several institutional levels and turns specialization into a source of interdependence.

The 228.7-point gap is particularly large in the economic, political, and technological dimensions. These components capture a state’s capacity not merely to benefit from integration but to produce alternatives, alter rules, and reduce switching costs. The minimal military gap is a reminder that institutional integration increases security more rapidly than it increases autonomous national military capacity.

Paraguay retains substantial formal sovereignty, including consensus in Mercosur and an equal share in Itaipu. Formal rights, however, do not always translate into agency when trade routes, buyers, and infrastructure are difficult to replace. Luxembourg has transferred more competences to an external system but gained access to rule-making, judicial protection, coalitions, markets, and collective security. In its case, the joint exercise of sovereignty has expanded the space for genuine choice in many areas.

The final thesis is as follows: the strategic autonomy of a small state is determined not by its distance from an external center, but by its capacity to influence that center’s rules, diversify supports, create new alternatives, set boundaries on participation, and preserve the internal reversibility of decisions. Integration reduces sovereign agency when it turns a single external channel into an irreplaceable one. It increases agency when it gives a small state several institutionally protected ways to act and makes the state’s own functions significant to the system as a whole.
