Kenneth Arrow’s “impossibility” theorem is rightly considered to be a landmark result in economic theory. It is a far-reaching result with implications not just for economics but for political science, philosophy, and many other fields. It has inspired an enormous literature, “social choice theory,” which lies on the interface of economics, politics, and philosophy. Arrow first proved the impossibility theorem in his doctoral dissertation—Social Choice and Individual Values—published in 1951. It is a remarkable result, and had Arrow not proved it, it is unlikely that the theorem would be known today.
A social choice is simply a choice made by, or on behalf of, a group of people. Arrow’s theorem is concerned more specifically with the following problem. Suppose that we have a given set of options to choose from and that each member of a group of individuals has his or her own preference over these options. By what method should we construct a single ranking of the options for the group as a whole? Any such method may be represented mathematically by a “social welfare function.” This is a function that receives as its input the preference ordering of each individual and then generates as its output a social preference ordering.
Arrow defined some properties that would seem to be essential to any reasonable social welfare function. These properties are called “unrestricted domain,” “weak Pareto,” “independence of irrelevant alternatives,” and “non-dictatorship.” Each of these properties, when taken alone, does appear to be very necessary indeed. Yet, Arrow proved that these properties are in fact mutually incompatible. This troubling fact has been central to the study of social choice ever since.

Cohesion Policy and European Union Politics
Simona Piattoni and Laura Polverari
Cohesion policy is one of the longest-standing features of the European construction; its roots have been traced as far back as the Treaty of Rome. Over time, it has become one of the most politically salient and sizable policies of the European Union, absorbing approximately one-third of the EU budget. Given its principles and “shared management” approach, it mobilizes many different actors at multiple territorial scales, and by promoting “territorial cooperation” it has encouraged public authorities to work together, thus overcoming national borders. Furthermore, cohesion policy is commonly considered the most significant expression of solidarity between member states and the most tangible way in which EU citizens “experience” the European Union.
While retaining its overarching mission of supporting lagging regions and encouraging the harmonious development of the Union, cohesion policy has steadily evolved and adapted in response to new internal and external challenges, such as those generated by subsequent rounds of enlargement, globalization, and shifting political preferences regarding what the EU should be about. Just as the policy has evolved over time in terms of its shape and priorities, so have the theoretical understandings of economic development that underpin its logic, the nature of intergovernmental relations, and the geographical and administrative space(s) within which the EU polity operates. For example, whereas overcoming the physical barriers to economic development were the initial targets in the 1960s and 1970s, and redesigning manufacturing clusters were those of the 1980s and 1990s, fostering advanced knowledge and technological progress became the focus of cohesion policy in the new century. At the same time, cohesion policy also inspired or even became a testing ground for new theories, such as multilevel governance, Europeanization, or smart specialization. Given its redistributive nature, debates have proliferated around its impact, added value, and administrative cost, as well as the institutional characteristics that it requires to function. These deliberations have, in turn, informed the policy in its periodic transformations.
Political factors have also played a key role in shaping the evolution of the policy. Each reform has been closely linked to the debates on the European budget, where the net positions of member states have tended to dominate the agenda. An outcome of this process has been the progressive alignment with wider strategic goals beyond cohesion and convergence and the strengthening of linkages with the European Semester. However, some argue that policymakers have failed to properly consider the perverse effects of austerity on regional disparities. These unresolved tensions are particularly significant in a context denoted by a rise of populist and nativist movements, increasing social discontent, and strengthening Euroskepticism. As highlighted by research on its communication, cohesion policy may well be the answer for winning back the hearts and minds of European citizens. Whether and how this may be achieved will likely be the focus of research in the years ahead.

Comparative Political Regimes: Consensus and Majoritarian Democracy
Matthijs Bogaards
Ever since Aristotle, the comparative study of political regimes and their performance has relied on classifications and typologies. The study of democracy today has been influenced heavily by Arend Lijphart’s typology of consensus versus majoritarian democracy. Scholars have applied it to more than 100 countries and sought to demonstrate its impact on no less than 70 dependent variables. This paper summarizes our knowledge about the origins, functioning, and consequences of two basic types of democracy: those that concentrate power and those that share and divide power. In doing so, it will review the experience of established democracies and question the applicability of received wisdom to new democracies.

Democratic Backsliding in the European Union
Nick Sitter and Elisabeth Bakke
Democratic backsliding in European Union (EU) member states is not only a policy challenge for the EU, but also a potential existential crisis. If the EU does too little to deal with member state regimes that go back on their commitments to democracy and the rule of law, this risks undermining the EU from within. On the other hand, if the EU takes drastic action, this might split the EU. This article explores the nature and dynamics of democratic backsliding in EU member states, and analyses the EU’s capacity, policy tools and political will to address the challenge. Empirically it draws on the cases that have promoted serious criticism from the Commission and the European Parliament: Hungary, Poland, and to a lesser extent, Romania. After reviewing the literature and defining backsliding as a gradual, deliberate, but open-ended process of de-democratization, the article analyzes the dynamics of backsliding and the EU’s difficulties in dealing with this challenge to liberal democracy and the rule of law. The Hungarian and Polish populist right’s “illiberal” projects involve centralization of power in the hands of the executive and the party, and limiting the independence of the judiciary, the media and civil society. This has brought both governments into direct confrontation with the European Commission. However, the EU’s track record in managing backsliding crises is at best mixed. This comes down to a combination of limited tools and lack of political will. Ordinary infringement procedures offer a limited toolbox, and the Commission has proven reluctant to use even these tools fully. At the same time, party groups in the European Parliament and many member state governments have been reluctant to criticize one of their own, let alone go down the path of suspending aspect of a states’ EU membership. Hence the EU’s dilemma: it is caught between undermining its own values and cohesion through inaction on one hand, and relegating one or more member states it to a second tier—or even pushing them out altogether—on the other.

The Economic and Monetary Union (EMU)
Lucia Quaglia
The Economic and Monetary Union (EMU) is one of the most important policy areas of the European Union (EU). Academic research on EMU in political science is well established and ever-evolving, like EMU itself. There are three main “waves” of research on EMU, which have mostly proceeded in a chronological order. The first wave of scholarly work has focused on the “road” to EMU, from the setting up of the European Monetary System in 1979 to the third and final stage of EMU in 1999. This literature has explained why and how EMU was set up and took the “asymmetric” shape it did, that is to say, a full “monetary union,” whereby monetary policy was conducted by a single monetary authority, the European Central Bank (ECB), but “economic union” was not fully fledged. The second wave of research has discussed the functioning of EMU in the 2000s, its effects and defects. EMU brought about significant changes in the member states of the euro area, even though these effects varied across macroeconomic policies and across countries. The third wave of research on EMU has concerned the establishment of Banking Union from 2012 onward. This literature has explained why and how Banking Union was set up and took the “asymmetric” shape it did, whereby banking supervision was transferred to the ECB, but banking resolution partly remained at the national level, while other components of Banking Union, namely a common deposit guarantee scheme and a common fiscal backstop, were not set up. Subsequently, the research has begun to explore the functioning of Banking Union and its effects on the participating member states.

From Elections to Democracy in Hard Times
Anna M. Meyerrose, Thomas Edward Flores, and Irfan Nooruddin
The end of the Cold War, heralded as the ideological triumph of (Western) liberal democracy, was accompanied by an electoral boom and historically high levels of economic development. More recently, however, democratic progress has stalled, populism has been on the rise, and a number of democracies around the world are either backsliding or failing entirely. What explains this contemporary crisis of democracy despite conditions theorized to promote democratic success?
Research on democratization and democracy promotion tends to focus predominantly on elections. Although necessary for democracy, free and fair elections are more effective at promoting democratic progress when they are held in states with strong institutions, such as those that can guarantee the rule of law and constraints on executive power. However, increased globalization and international economic integration have stunted the development of these institutions by limiting states’ economic policy options, and, as a result, their fiscal policy space. When a state’s fiscal policy space—or, its ability to collect and spend revenue—is limited, governments are less able to provide public goods to citizens, politicians rely on populist rather than ideological appeals to win votes, and elections lose their democratizing potential.
Additional research from a political–economic framework that incorporates insights from studies on state building and institutions with recent approaches to democratization and democracy promotion, which focus predominantly on elections, is needed. Such a framework provides avenues for additional research on the institutional aspects of ongoing democratization and democratic backsliding.

Globalization and Regionalism in Africa
Pádraig Carmody
Globalization, or increased interconnectedness between world regions, is a dialectical and recursive phenomenon that consequently tends to deepen through time as one set of flows sets off other related or counterflows. This is evident in the history of the phenomenon in Africa, where transcontinental trade, and later investment, were initially small but have grown through different rounds including slavery, colonialism, neocolonialism, and the early 21st-century era of globalization. However, globalization on the continent, as in other places, is not unilinear and has generated a variety of “regional responses” in terms of the construction of organizations such as the African Union and other more popularly based associations. The phenomenon of globalization on the continent is deepening through the information technology “revolution,” which also creates new possibilities for regional forms of association.

Land-Related Conflict and Electoral Politics in Africa
Catherine Boone
Land-related disputes and land conflicts are sometimes politicized in elections in African countries, but this is usually not the case. Usually, land-related conflict is highly localized, managed at the micro-political level by neo-customary authorities, and not connected to electoral competition. Why do land conflicts sometimes become entangled in electoral politics, and sometimes “scale up” to become divisive issues in regional and national elections? A key determinant of why and how land disputes become politicized is the nature of the underlying land tenure regime, which varies across space (often by subnational district) within African countries. Under the neo-customary land tenure regimes that prevail in most regions of smallholder agriculture in most African countries, land disputes tend to be “bottled up” in neo-customary land-management processes at the local level. Under the statist land tenure regimes that exist in some districts of many African countries, government agents and officials are directly involved in land allocation and directly implicated in dispute resolution. Under “statist” land tenure institutions, the politicization of land conflict, especially around elections, becomes more likely. Land tenure institutions in African countries define landholders’ relations to each other, the state, and markets. Understanding these institutions, including how they come under pressure and change, goes far in explaining how and where land rights become politicized.

Political Parties and Political Economy in Africa’s Democracies, 1990–2018
M. Anne Pitcher
On a continent where the majority of people are poor, do political parties represent class cleavages? Do parties have strong linkages to ordinary voters? Do economic policies address their needs? In the initial years following democratic transitions across the African continent in the 1990s, the answers to such questions were negative. Clientelism and patronage were the principal means by which parties interacted with their constituencies; elites and elite interests determined the objectives of political parties; voters in many African countries shifted parties frequently; and neoliberal economic policies largely reflected the preferences of foreign donors and international financial institutions. As parties and voters have adjusted to the institutional arrangements and political demands associated with democracy, a more heterogeneous political landscape has materialized since 2010. Party systems demonstrate distinct patterns of variation, from the more stable, institutionalized systems in Ghana and Botswana to fluid, inchoate configurations in Benin and Malawi. These variations in the degree to which party systems have institutionalized affect economic policy choices by parties and those who benefit from them. Furthermore, democratic politics has intensified pressures on ruling parties to provide goods such as electricity and education. Here too, patterns of goods provision show substantial variation over time and across countries, calling attention to the differences in the incentives and capacities of parties to respond to distributive demands by the electorate.
To explore the political and economic heterogeneity of contemporary Africa, scholars have combined well-established qualitative and comparative approaches with new analytical tools. The use of cross-national public opinion surveys, field and survey experiments, satellite imagery, and geo-coded data have enabled more systematic, fine-grained study of the economic determinants of party system competition, economic voting, the distribution of goods, and the management of private sector development by ruling parties in recent years. These empirical approaches enrich understanding of the relationship between parties and political economy in Africa and facilitate more fruitful comparisons with other regions of the world.

Populist Politics in Africa
Danielle Resnick
Although widely used in reference to the Americas and Europe, the concept of populism has been less frequently applied to political dynamics in sub-Saharan Africa. Populism is variously viewed as a political strategy aimed at fostering direct links between a leader and the masses, an ideational concept that relies on discourses that conjure a corrupt elite and the pure people, and a set of socio-cultural performances characterized by a leader’s charisma, theatrics, and transgression of accepted norms. A cumulative approach that combines all three perspectives allows for identifying episodes of populism in Africa. These include historical cases of populist regimes in the 1980s as well as more contemporary examples of party leaders in the region’s democracies who use populism in their electoral campaigns to mobilize subaltern groups, especially those living in urban areas. As found in other regions of the world, those African leaders who have ascended to the presidency on the back of populism typically exert anti-democratic practices once in office. This reaffirms that populism can allow for greater representation of the poor and marginalized in the electoral process, but that populists’ celebration of popular will and supposedly unmediated ties to the people become convenient justifications for bypassing established institutions and undermining the rule of law.

Regulatory Governance: History, Theories, Strategies, and Challenges
David Levi-Faur, Yael Kariv-Teitelbaum, and Rotem Medzini
Regulation, that is, rulemaking, rule monitoring, and rule enforcement, is both a key policy and legal instrument and a pillar of the institutions that demarcate political, social, and economic lives. It is commonly defined as a sustained and focused control mechanism over valuable activities using direct and indirect rules. Most frequently, regulation is associated with the activity of public independent regulatory agencies, designed to promote economic, social, risk-management, integrity, or moral goals. Since the 1990s, more and more states worldwide are establishing such agencies and placing more emphasis on the use of authority, rules, and standard-setting, thus partially displacing earlier emphasis on public ownerships and directly provided services. Alongside this rise of the “regulatory state,” the expansion of regulation is also reflected in the rapidly growing variety of regulatory regimes that involves nonstate actors, such as private regulation, self-regulation, and civil regulation. Regulatory regimes can be explained and assessed from three theoretical perspectives: public-interest theories, private-interest theories, and institutional theories. Each perspective shines a different light on the motivations of the five regulatory actors: rule-makers, rule intermediaries, rule-takers, rule beneficiaries, and citizens. Over the years, diverse regulatory strategies evolved, including: prescriptive strategies that attempt to mandate adherence in precise terms what is required from the rule-takers; performance-based strategies that set in advance only the required outcomes; and process-based strategies that attempt to influence the internal incentives and norms of rule-takers. Although it appears that regulation is here to stay as a keystone of society, it still faces fundamental challenges of effectiveness, democratic control, and fairness.

Transport Policy and European Union Policy
Cyril Alias, Bernd Kleinheyer, and Carla Fieber-Alias
In an integrated European Union, transport would be expected to be a major enabler of economic development and consumer services. This role, however, was not acknowledged, though laid down in initial treaties, until 30 years into the EU’s existence. A verdict of the European Court of Justice condemning the longstanding inactivity of the European Council and subsequent efforts toward a dedicated policymaking have changed the significance. The regular definition and monitoring of goals and objectives in European transport policy by means of White Papers and trans-European transport networks guide public attention to the policy area. From an initial stage, when transport was considered as a functional enabler for cooperation after World War II, transport has evolved toward a Community task, featuring a long phase of stagnation and a sudden change to actionism after the court verdict. From the 1990s onward, goals like liberalization, cohesion, environmental protection, modal shift, competitiveness, globalization, and resource efficiency characterize European transport policy. Despite the output failure in European transport policy over many years, the Single European Market propelled transport onto the center stage of European policies and later made it a key object of sustainability policies. This change in focus has also attracted citizens’ attention with the effect that the EU needs and manages to portray itself as an interactive and accountable legislator dialoguing with its population. This new openness is a mere necessity if the EU wants to pursue its goal of a Single European Transport Area that is both supported by its business and citizens. At the same time, European transport policy is subject to numerous external influences—both by other European and national policies and different stakeholder interest groups. The ordinary legislative procedure is preceded by the initial agenda setting over the proposal planning and issuing and ranges from the proposal to three readings before being passed by European Parliament and Council of Ministers. The stakeholders accompany the whole process and influence it at different stages. Several examples from the history of European transport policymaking are proof of this.
