Introduction
The structure of the international system is shifting away from being unipolar into a
multipolar ecosystem with fierce competition between states. Following the cold war, American
dominance has gradually faltered and given way to a geopolitical landscape dominated by the
European Union, China, and the United States (Walt, 2011). This shift toward multipolarization,
understood as a system in which no single state dominates global politics, raises important
questions about the internal characteristics that shape countries’ positions within this emerging
order. Currently, much of the discussion surrounding multipolarity focuses on economic growth,
military capability, and geopolitical strategy, but what can a state's cohesion say about their
prosperity? Can any government system produce prosperity? Or are there dominant systems
within this multipolarized landscape?
This essay addresses these questions by examining how the transition toward a multipolar
international order affects the distribution of risks and opportunities faced by the United States,
China, and the European Union. Rather than arguing that a single model of governance
guarantees prosperity or dominance, the analysis suggests that multipolarity is defined by
diversity rather than convergence. States with fundamentally different political and institutional
arrangements can simultaneously exercise influence and generate economic value, albeit through
distinct pathways. In doing so, the essay argues that structural economic and geopolitical factors
matter more than internal political cohesion alone in shaping outcomes within the contemporary
international system.
Conceptual Framework
This study draws on three key concepts: government party cohesion, economic
prosperity, and multipolarization as defined below.
Multipolarization describes the transition from a system led by a single dominant power
to one in which multiple states exercise significant influence. Contemporary multipolarity
includes wealthy democracies, authoritarian states, and emerging economies. Although this
analysis does not measure multipolarity directly, it uses the concept to explain why internal
political cohesion alone does not determine global status.

Governance diversity captures the variation in political and institutional arrangements
across states. Rather than treating political cohesion as a deterministic variable, this essay views
governance structures as one among many factors that interact with broader economic,
demographic, and technological conditions. In a multipolar world, governance diversity is not an
anomaly but a defining feature, allowing different systems to coexist without converging on a
single dominant model.
Economic prosperity is measured through GDP per capita (PPP) because it provides one
of the clearest and most widely accepted indicators of a population’s average material standard of
living. GDP per capita captures how much economic output is available per person and therefore
reflects a state's ability to generate wealth relative to its population size. Using purchasing power
parity (PPP) further adjusts for differences in price levels across countries, making the measure
more comparable internationally. This is especially important in a study that includes both
advanced economies and emerging powers, where nominal GDP figures can be misleading.
Although GDP per capita does not capture all aspects of development, such as inequality, quality
of public services, or broader well-being, it remains the most consistent measure for
cross-national comparison. In the context of multipolarity, it also serves as a useful proxy for
understanding the economic foundations behind a state's ability to exert influence on the global
stage.
Research Design and Operationalization
The study employs a comparative cross-case exploratory analysis), comparing countries
that differ sharply in regime type, institutional arrangements, culture, development level, and
population size. Despite these contrasts, all selected states operate within, and help shape, the
emerging multipolar international order. This design allows the analysis to isolate whether the
relationship between party cohesion and prosperity persists across highly divergent political
contexts. The causal framework consists of two variables: the dependent variable, economic
prosperity (measured as GDP per capita, PPP, 2014), and the independent variable, government
party cohesion (GovParty_mean). If cohesion were positively associated with prosperity, states
with high GovParty_mean scores would be expected to cluster at the top of the economic
4 Fioranelli
distribution. The hypothesis challenges this expectation by testing whether economic outcomes
instead vary independently of political cohesion.
Empirical Analysis
To test the hypothesis, the analysis reviews both descriptive statistics and visualizations
relating GovParty_mean and GDP per capita. The relationship between GDP per Capita and
Government Cohesion between the United States, China, France, Japan, United Kingdom,
Brazil, India, and Germany can be seen in the scatter plot below:
Table 1 & 2. GDP per Capita and Government Cohesion (Select Countries) & GDP per Capita
and Government Cohesion (Randomized Western Countries)
Table 3 & 4. Isolated GDP per Capita and Government Cohesion Bar Charts
As seen from the tables above, the descriptive comparison of the selected countries
reveals substantial variation in both government-party cohesion (GovParty_mean) and economic
prosperity (GDP per capita).

Graph 1, the scatterplot of GDP per capita against GovParty_mean, provides a clearer
sense of the relationship between the two variables. The data points form no visible upward or
downward trend. The United States achieves one of the highest levels of prosperity in the world
despite only moderate party cohesion. China, by contrast, combines perfect party dominance
with significantly lower GDP per capita compared to wealthy democracies. Meanwhile,
Germany, France, the United Kingdom, and Japan, all democracies with mid-range cohesion,
occupy the upper end of the prosperity scale. India and Brazil fall toward the lower end of GDP
per capita regardless of differing levels of cohesion. Put together with Graph 2, the trend is
equally present with a randomized set of Western European countries with varying political
views, institutions, sizes, and more.
Graph 3 presents the distribution of GovParty_mean across the sample. The results show
sharp contrasts. China sits at the extreme end with perfect cohesion (100), while advanced
democracies such as France, Germany, the United Kingdom, and Japan cluster between 40 and
60. India and Brazil, both large emerging economies, exhibit lower cohesion scores despite their
demographic size.
Graph 4 further reinforces the empirical pattern by ranking GDP per capita across the
selected countries. The United States stands out as the most prosperous case, far surpassing all
others despite only moderate government-party cohesion. Germany, the United Kingdom,
France, and Japan also appear as high-income states, clustering closely together with GDP per
capita figures between roughly 36,000 and 45,000. China and the United States, marked in red,
fall at opposite sides of the spectrum.
To statistically assess the association between the two variables, the analysis calculates a
Pearson correlation coefficient using the paired values of GovParty_mean and GDP2014. The
resulting coefficient, r = –0.42, indicates a moderate negative relationship. In practical terms, this
means that higher levels of government-party cohesion tend to be associated with lower levels of
economic prosperity, though the relationship is not strong enough to imply a deterministic
pattern. The calculation was performed by correlating the two datasets, GDP per capita and
GovParty_mean, across the limited selected cases from Graph 1.
United States Results

Despite increasing domestic political fragmentation, the United States remains one of the
most influential and prosperous actors in the international system. This case illustrates that
political cohesion alone does not necessarily produce strength, a pattern that is particularly
evident in the U.S. context (Walt, 2011). The country’s structural advantages, including deep and
liquid capital markets, technological leadership, and the continued dominance of the U.S. dollar
as the primary global reserve currency, have historically solidified its position as a global power
(Tooze, 2018). However, recent political polarization and volatility, particularly surrounding
tariff-related policy decisions, have raised concerns about the long-term stability of this position.
Such volatility has prompted debates over whether the United States should continue to occupy
its current level of influence within the global financial and political system.
Multipolarity introduces significant risks for the United States, especially in light of its
internal political divisions. Political gridlock, declining trust in institutions, and the risk of
strategic overextension may undermine its ability to act consistently and credibly on the global
stage. At the same time, proponents of protectionist and pro-tariff policies argue that such
measures are necessary to consolidate domestic resources, promote economic nationalism, and
restore long-term prosperity. While these arguments resonate with certain segments of the
electorate, they have also contributed to growing uncertainty among international partners. As a
result, trust in the United States as a reliable diplomatic and economic actor has weakened, and
its leadership role is increasingly being questioned.
Nonetheless, the flexibility of U.S. institutions and the country’s accumulated historical
power continue to insulate it from the immediate consequences of internal political
fragmentation. The United States retains a unique capacity to absorb short-term volatility without
a rapid loss of global influence. Whether sustained political polarization will ultimately alter its
position within the multipolar order remains an open question and would require longer-term
analysis to determine if recent trends represent a structural shift rather than a temporary
deviation.
China Results
In contrast to the United States, China represents a distinct pathway within the emerging
multipolar order. It is often characterized as a highly centralized system that enables rapid
7 Fioranelli
decision-making and long-term strategic planning. While the absence of competitive elections
complicates conventional understandings of political cohesion, China nevertheless exhibits a
high degree of institutional control and policy continuity (Naughton, 2018). This governance
structure has been particularly effective in advancing large-scale infrastructure development,
industrial policy, and technological upgrading. Together, these strategies have driven
extraordinary economic growth over the past four decades and enabled China to challenge U.S.
dominance across multiple strategic sectors. Although China has not yet surpassed the United
States in several key technological domains, it has emerged as the primary competitor in areas
such as artificial intelligence.
Like the United States, China faces significant structural constraints that complicate its
continued rise. Demographic decline, rising levels of debt, and increasing external pressure from
trade restrictions and technological decoupling limit its long-term growth prospects and reduce
the likelihood of full convergence with the U.S. model of economic power. While centralized
governance can facilitate coordination and rapid policy implementation, it also concentrates risk
and limits institutional adaptability (Naughton, 2018). As a result, China’s position within the
multipolar system reflects both the strengths and vulnerabilities of state-led development.
Discussion
The results clearly indicate that government party cohesion does not meaningfully predict
economic prosperity, even within a group of countries that differ widely in political institutions
and levels of development. This finding is significant for understanding the structure of the
emerging multipolar world. In practice, states with highly distinct institutional arrangements can
achieve comparable levels of economic wealth and global influence. China’s near-total party
cohesion does not produce higher income levels than those of competitive democracies, while
countries such as the United States, Germany, and France maintain some of the world’s highest
GDP per capita levels despite comparatively more fragmented legislatures and frequent political
turnover.
The absence of a strong relationship between cohesion and prosperity also illustrates the
importance of broader structural drivers of economic performance. Future analyses should
8 Fioranelli
incorporate additional economic indicators, such as technological capacity, state administrative
strength, trade integration, resource endowments, and long-term development trajectories, to
better understand what actually shapes prosperity. Incorporating appropriate control variables
would further help isolate the effects of political cohesion from these deeper structural
determinants. Such structural factors likely play a far more consequential role in long-run
economic performance than the degree of parliamentary unity alone. This may explain why
wealthy democracies with moderate cohesion, highly cohesive but less prosperous authoritarian
systems, and rapidly developing emerging economies all coexist as influential actors within the
international system.
Taken together, these findings illustrate that multipolarity is inherently diverse. The
leading powers of the 21st century do not share a single model of governance, nor are they
converging toward one. Instead, the global order includes a mixture of liberal democracies,
centralized authoritarian states, and hybrid regimes, all capable of projecting meaningful
influence. Such heterogeneity is a defining feature of contemporary multipolarization and
challenges any assumption that political cohesion alone determines a state’s economic or
strategic standing.
Risks and Opportunities
The shift from a unipolar to a multipolar international order presents a complex mix of
risks and opportunities for major global actors (Wohlforth, 1999). Unlike the relatively stable
structure associated with unipolarity, multipolar systems are characterized by more diffuse
distributions of power, heightened strategic uncertainty, and overlapping spheres of influence.
Similar to dynamics observed in economic markets, this diffusion of power can encourage
greater diversity in development paths and governance strategies, reducing reliance on a single
hegemon. At the same time, multipolarity increases the likelihood of instability, global
fragmentation, coordination failures, and asymmetric power dynamics among states.
Global fragmentation represents one of the most significant risks associated with
multipolarization. As power becomes more dispersed, no single actor possesses sufficient
authority to consistently shape outcomes or enforce collective decisions. Consequently, global
governance institutions play an increasingly important role in facilitating cooperation, yet they
9 Fioranelli
themselves face mounting strain. Multilateral frameworks originally designed around U.S.
leadership, such as the World Trade Organization and the United Nations, have struggled to
adapt to intensifying competition among major powers (Allison, 2017). This fragmentation
weakens the international community’s ability to coordinate effective responses to global
challenges, including armed conflict, financial crises, and climate change. The absence of a clear
global hegemon further complicates enforcement, as treaties and norms become more difficult to
uphold without a central authority capable of imposing compliance. For emerging and middle
powers, these dynamics are particularly challenging, as increased fragmentation often leads to
reduced predictability and diminished influence within the international system.
​
A second major risk stems from intensified strategic competition, particularly between
the United States and China. Within a multipolar context, economic interdependence
increasingly coexists with geopolitical rivalry (Farrell & Newman, 2019). As demonstrated by
recent trade disputes, tariffs, technological decoupling, and the emergence of competing
standards regimes have become instruments of strategic competition rather than purely economic
policy tools. This rivalry generates heightened uncertainty for all actors within the multipolar
order, while simultaneously increasing costs by disrupting global supply chains and reducing
efficiency gains derived from specialization.
Contrary to the expectation that increased competition would lower prices, recent trends
suggest the opposite effect. Heightened strategic rivalry has contributed to rising costs over the
past decade, as firms face duplicated supply chains, regulatory fragmentation, and reduced
economies of scale. For the European Union in particular, this dynamic poses a significant
challenge. The EU must navigate the tension between maintaining economic openness and
pursuing greater strategic autonomy, all while avoiding excessive dependence on either the
United States or China. As a result, geopolitical competition between major powers increasingly
constrains policy choices for third actors within the multipolar system.
Despite these risks, multipolarity may offer substantial opportunities when compared to a
unipolar order (Wohlforth, 1999). The absence of a single dominant model reduces normative
pressure on states to conform to a specific institutional template. As discussed above, prosperity
is not necessarily predicted by any one form of government. Instead, different governance
10 Fioranelli
systems can pursue development strategies aligned with their domestic conditions, allowing for
greater flexibility in economic policy, industrial planning, and social regulation. This
environment fosters competition in which successful approaches can diffuse more organically,
rather than through coercion, enabling states to chart distinct paths to development and influence.
In theory, major powers may also benefit from power-sharing arrangements that enable
collective responses to global challenges. Although cooperation in a multipolar system is often
difficult, such a structure can promote more inclusive technological and scientific collaboration.
One example is international cooperation in nuclear fusion research through tokamak-based
projects involving seven major partners. While such initiatives remain relatively rare, regional
coordination, particularly among established alliances, has strengthened in recent years,
alongside increased technological cooperation and joint development planning. China, for
instance, has leveraged centralized state coordination and long-term planning to advance
infrastructure development, technological upgrading, and South–South cooperation. Similarly,
the European Union, despite internal fragmentation, has exercised influence through its
regulatory power and market size, shaping key policies in areas such as data governance,
artificial intelligence, and competition policy.
In this sense, multipolarity creates meaningful opportunities to rebalance the relationship
between power and legitimacy. Unlike unipolar systems, where dominance is often substituted
for consent, multipolar orders require states to justify leadership through performance and
cooperation (Wohlforth, 1999). This dynamic incentivizes innovation, growth, and negotiated
forms of governance. Although these processes are slower and more complex, they may
ultimately produce more resilient states and more adaptable forms of international order.
Conclusion
This analysis tested whether higher government party cohesion is associated with higher
economic prosperity and found no evidence to support such a relationship using GDP per capita.
Employing a Most Different Systems Design, the comparison demonstrated that countries with
vastly different political structures can achieve either similar or sharply different levels of
economic wealth. The lack of correlation suggests that prosperity is shaped primarily by
structural economic factors rather than by legislative unity or executive dominance. In the
11 Fioranelli
context of a multipolarizing world, this finding helps explain why states with divergent
institutional designs, including China, the United States, and major European economies, can all
act as influential global powers. Ultimately, the results reinforce the argument that no single
model of governance guarantees prosperity or global standing.
