The balance of power—a notoriously slippery, murky, and protean term, endlessly debated and variously defined—is the core theory of international politics within the realist perspective. A “balance of power” system is one in which the power held and exercised by states within the system is checked and balanced by the power of others. Thus, as a nation’s power grows to the point that it menaces other powerful states, a counter-balancing coalition emerges to restrain the rising power, such that any bid for world hegemony will be self-defeating. The minimum requirements for a balance of power system include the existence of at least two or more actors of roughly equal strength, states seeking to survive and preserve their autonomy, alliance flexibility, and the ability to resort to war if need be.
At its essence, balance of power is a type of international order. Theorists disagree, however, about the normal operation of the balance of power. Structural realists describe an “automatic version” of the theory, whereby system balance is a spontaneously generated, self-regulating, and entirely unintended outcome of states pursuing their narrow self-interests. Earlier versions of balance of power were more consistent with a “semi-automatic” version of the theory, which requires a “balancer” state throwing its weight on one side of the scale or the other, depending on which is lighter, to regulate the system. The British School’s discussion of balance of power depicts a “manually operated” system, wherein the process of equilibrium is a function of human contrivance, with emphasis on the skill of diplomats and statesmen, a sense of community of nations, of shared responsibility, and a desire and need to preserve the balance of power system.
As one would expect of a theory that made its appearance in the mid-16th century, balance of power is not without its critics. Liberals claim that globalization, democratic peace, and international institutions have fundamentally transformed international relations, moving it out of the realm of power politics. Constructivists claim that balance of power theory’s focus on material forces misses the central role played by ideational factors such as norms and identities in the construction of threats and alliances. Realists, themselves, wonder why no global balance of power has materialized since the end of the Cold War.
The idea that states should provide a means-tested guaranteed minimum income for citizens who are unable to meet their basic needs is widely shared and has been a central component in the evolution of social citizenship rights in existing welfare states. However, an increasing number of activists and scholars defend the more radical option of establishing a universal basic income, that is, an unconditional income paid to all members of society on an individual basis without any means test or work requirement. Indeed, some political philosophers have argued that basic income is one of the most important reforms in the development of a just and democratic society, comparable to other milestones in the history of citizenship rights, such as universal suffrage or even the abolishment of slavery. Basic income or similar ideas, such as a basic capital or a negative income tax, have been advanced in many versions since the 18th century in different parts of the world and under a great variety of names. However, while these were previously often isolated and disconnected initiatives, basic income has more recently become the object of an increasingly cumulative research effort to shed light on the many aspects of this idea. It has also inspired policy developments and given rise to experiments and pilot projects in several countries.

Policies as diverse as tariffs, exchange rates, and unemployment insurance vary across democratic countries. In an attempt to explain this cross-national variation, scholars have turned to the institutions that govern countries’ elections. The institutions that regulate elections, also known as an electoral system, vary significantly across democracies. Can these varied electoral institutions explain the diversity of policies observed? This question remains unanswered. Despite a growing body of research, little consensus exists as to precisely how electoral institutions affect policy. Why is it so difficult to untangle the effects of electoral institutions on economic policy? One reason for the confusion may be the imprecise manner in which electoral institutions are often measured. Better measures of electoral systems may improve our understanding of their policy effects. Improved theories that clarify the causal mechanism(s) linking electoral systems to policy outcomes will also help to clarify the relationship between electoral systems and policies. To better understand the policy effects of electoral institutions, both theoretical and empirical work must take seriously contextual factors, such as geography, which likely mediate the effects of electoral institutions. Finally, different types of empirical evidence are needed to shed new light on the policy effects of electoral institutions. It is difficult to identify the effects of electoral systems in cross-national studies because of the many other factors that vary across countries. Examining within-country variations, such as changes in district magnitude, may provide useful new insights regarding the effects of electoral institutions on policy.
“A Marriage of Convenience” became the best metaphor, coined in 1990 by distinguished American economist Sidney Weintraub to summarize the fundamentals under which NAFTA was built and understood, at least in mainstream analysis: the economic complementarities existing among the three countries of North America could work to the benefit of everyone involved if economic integration is well managed and geared toward the improvement of regional competitiveness. Thus, NAFTA became the privileged tool under which managed integration became implemented and assessed, at least in three major domains: as a foreign policy tool to advance the interests of each nation, as an economic device to reap the benefits of integration, and as the backbone under which a regional political and social bloc could eventually be constructed.
Scholars, intellectuals, and public officials engaged in the discussions around NAFTA in each of those fields shared ideas, built some consensus, and split on dissents following competing approaches and/or national cleavages. The current literature in those three major fields of discussion is rich, voluminous, and highly inspiring, sometimes making references to other integrative experiences. This article reviews these debates and highlights either the consensus or dissention witnessed in each of the three domains under which NAFTA has been discussed the most. Since NAFTA cannot be separated from the political and social contexts that the debates and discussions took place in, a reference to those political contexts can be made when explaining and summarizing the debates.
At a time when the mainstream consensus around NAFTA is being challenged by U.S. President Trump’s assumption that NAFTA is not about complementary economies but about economies competing against each other under a zero-sum game rationale, politics comes back to the forefront of North American affairs. The renegotiation of NAFTA will doubtless redefine the partnership among the three North American countries and the role that economic cooperation and integration entails for each.
To what extent is the “Euro-crisis” a problem for the EU’s international standing and role? A conceptual framework has been developed based on the five distinct analytical categories: (a) financial resources, (b) changes in the internal political structure and balance of the European Union, (c) shift of priorities, (d) output and effectiveness of EU foreign policy, and (d) soft power and normative dimension. These categories reveal that in Europe, the crisis led to an erosion of the financial and budgetary basis of foreign policy—even if it is more pronounced on the national than the European level. It also accelerated a trend toward the economization of political priorities resulting—among other things—in deepening conflicts among EU member states. These developments have, in turn, eroded both the effectiveness and the soft power of EU foreign policy. The crisis is therefore not only a strain on the European integration process but also a central challenge for the European Union as an international actor.
Which risks are social and which are private? How much of their GDP do states spend on social welfare? Who exactly is entitled to which benefits? Is it still possible to finance an encompassing welfare state in times of deindustrialization, technological and demographic change, and globalization? And why do the answers to these questions differ so much across countries? These and similar questions—all central to social cohesion in capitalist democracies—ensure that the analysis of welfare politics is one of the theoretically as well as methodologically most dynamic and richest research areas within comparative political economy and political science more generally. Besides outlining the comparative development and the difficulty of measuring social policy, the focus of this contribution lies in a critical review of the most important past and current theoretical debates in the field of welfare state research, as a subfield of comparative political economy. These debates include party- and power-resource-centered approaches and their critiques, institutional explanations of welfare state retrenchment and restructuring, and the importance of multidimensional distributional effects for the analysis of social policy. The article concludes with a review of three more recent debates: the importance of public opinion and individual preferences for the development of the welfare state, the interaction of social policy and the changes of party systems, and the increasing relevance of social investment policies. The political and scientific need for innovative political science research will continue for the foreseeable future: Theory building and methodological possibilities are developing quickly, and the welfare states as research subject are constantly being challenged.
