Essentially all scholars agree that the levels of violent conflict, especially wars, within democratic pairs of states are significantly lower than levels of violent conflict within other pairs of states. However, debate rages as to whether this observed correlation is causal or spurious. Does democracy actually cause peace? Answering this question is critical for both scholarly and policy debates.
Critics have lodged two sets of arguments proposing that the observed correlation between democracy and peace does not mean that democracy causes peace. First, some claim that the peace observed among democracies is not caused by regime type, but rather by other factors such as national interest, economic factors, and gender norms. These critics often present statistical analyses in which inclusion of these or other factors render the democracy independent variable to be statistically insignificant, leading them to draw the conclusion that democracy does not cause peace.
The second critique claims that there is a causal relationship between democracy and peace, but peace causes democracy and not the reverse. Peaceful international environments permit democracy to emerge, and conflictual international environments impede democracy. Though peace causes democracy, democracy does not cause peace.
Careful examination of the theoretical claims of these critiques and especially the pertinent empirical scholarship produces two general conclusions. First, there is enough evidence to conclude that democracy does cause peace at least between democracies, that the observed correlation between democracy and peace is not spurious. Second, this conclusion notwithstanding, the critiques do make important contributions, in the sense that they demonstrate that several factors (including democracy) cause peace, that there may be some qualifications or limitations to the scope of the democratic peace, and that causality among factors like democracy and peace is likely bidirectional, part of a larger dynamic system.

Crucial to understanding the behavior of judges and the outputs of courts is the institutional context in which they operate. One key component of courts’ institutional structure is that the judiciary is organized as a hierarchy, which creates both problems and opportunities for judges. For instance, one problem for judges at the top of a hierarchy is how to best exercise oversight of lower court judges, whose decisions are often not reviewed by higher courts. One opportunity is that higher courts can reverse errors by lower courts; another is that, as new legal issues emerge, hierarchy provides opportunities for judges to learn from one another.
Scholars of the judicial hierarchy have pursued two broad approaches. The “team perspective” begins by assuming that all judges in a hierarchy have the same values or principles, and thus care only about achieving the correct outcome in a given case. In the team approach, the key problem in adjudication is informational. All judges agree on the correct outcome of a case, conditional on understanding the relevant facts, but may lack this understanding due to resource constraints or informational advantages enjoyed by litigants. The agency approach, by contrast assumes that judges in the hierarchy have differing preferences, and the key problem is how higher courts can ensure compliance by lower courts.
Despite these different foundational assumptions, the team and agency approaches have both been employed successfully to study core questions regarding the judicial hierarchy, including: why hierarchy exists; how higher courts can best oversee lower courts; how learning takes place both within and across the levels of the judiciary; and how collegiality influences judicial decision-making. Yet, while our understanding of the judicial hierarchy has greatly increased in recent years, many questions remain, such as how judges learn and how to measure legal doctrine.

Scholars have long been interested in judicial impact—the ability of courts to meaningfully alter policy or politics—because judicial decisions shape law, have the potential to affect many people, and may even implicate democracy in a fundamental sense. Classic studies in this tradition concern the degree to which actors outside the court comply with judicial decrees, such as whether or not (or to what extent) schools desegregated in the wake of Brown v. Board of Education. However, scholars working in a variety of other traditions have likewise examined the impact of judicial decisions, though they have not always used those terms. For example, advocates of interbranch analysis have situated courts within broader ongoing policy processes, and in so doing have documented repeated instances in which policy outcomes were altered by the actions of lawyers and judges. Likewise, students of legal mobilization have documented the sometimes constitutive effects of legal ideas on a wide range of political identities, attitudes, and behaviors. In short, the concept of impact includes a variety of ways in which courts influence politics, and the field of judicial impact studies will continue to benefit from a vital diversity of methods of inquiry, subjects of analysis, and conceptions of law.

A broad international consensus supports the view that ensuring judicial independence is a normatively appealing goal, either because independence is itself a virtue or because it is believed to set the conditions for many other normatively appealing goals. Academic research on the subject raises questions about what independence is and whether it is a useful concept at all. Scholars question whether independence can be designed, and if so, under what conditions. Assuming that judicial independence can be generated, scholars also question whether it will produce the ends we desire. This diversity of opinion is driven by the fact that judicial independence is a product of potentially complicated political processes. Scholars disagree about how these processes work. Particular theoretical models of the political systems in which judges are embedded have clear implications for all aspects of the research process, from conceptual development to causal inference. Absent theoretical consensus on the way that politics works in particular places, we cannot expect consensus over the nature, construction, and effects of judicial independence. The implication of this view is that reform efforts must be guided as much by the theoretical and normative orientations of designers. What scholars can do is help designers make their theoretical and normative commitments transparent.
What does current scholarship suggest about the relationship between the rights of workers in the developing world and the global economy? Contemporary multinational production includes both direct ownership of manufacturing facilities abroad and arm’s length subcontracting and supply chain relationships. Thus far, political economists have paid greater attention to the former; there are various reasons to expect that multinational firms may have positive, rather than negative, effects on workers’ rights. For instance, some multinationals are interested in hiring at the top end of local labor markets, and high standards serve as a tool for recruitment and retention. Multinationals also could bring “best practices” from their home countries to their local hosts, and some face pressure from shareholders and consumers—given their visibility in their home locations—to act in “socially responsible” ways. Hence, while directly owned production does not automatically lead to the upgrading of labor standards, it can do so under some conditions.
Supply chain production is likely more mixed in its consequences for workers. Such production involves arm’s length, subcontracted production, in which multiple potential suppliers typically compete to attract business from lead firms. Such production often includes more labor-intensive activities; minimizing costs (including labor costs) and lowering production times can be key to winning subcontracts. We may therefore expect that subcontracted production is associated with greater violations of labor rights. It is worth noting, however, that research regarding the consequences of supply chain production—and the conditions under which such production may lead to improvements for workers—is less advanced than scholarship related to foreign direct investment.
The governance of labor rights in a supply chain framework is marked by several challenges. It is often difficult for lead firms, even those that wish to protect worker rights, to effectively monitor compliance in their subcontractor facilities. This becomes more difficult as the length and breadth of supply chains grow; private governance and corporate social responsibility have therefore not always lived up to their promise. Rather, achieving labor protections in a supply chain framework often requires both private and public sector efforts—that is, governments that are willing to privilege the rights of workers over the rights of local factory owners and governments that are willing to enact and implement legal protections of core labor rights. Such government actions, when coupled with private sector–based capacity building, codes of conduct, and regular monitoring, offer the most promise for protecting labor rights within global supply chains. Finally, governments of developed countries also may play a role, if they are willing to credibly link working conditions abroad with market access at home.

Puzzles for the scholar of international relations abound in Latin America, whether one focuses on unexpected outcomes or examines purported causal variables that, when properly specified, do not lead where theory expects. In fact, the Latin American experience is a great case to illustrate two problems in the empirical application of international relations theories: theoretical formulations tend to be poorly developed and articulated, and the empirical evaluations of those theories are not rigorously designed.
The empirical record of Latin American interstate violence is more present and varied than generally accepted by scholars and policy makers. The relationship between conflict and the region’s use of international fora to peacefully resolve some conflicts obscures this record. Puzzles also arise when explaining why the region has the empirical record it does since the causal logic underlying the variables is generally misspecified in studies of Latin American security relations. These analytic errors render most explanations offered in the literature drawing on Latin American cases incorrect. Indeed, the failed explanations themselves offer new puzzles for scholars of international relations. Scholars of international relations can, therefore, benefit from studying the actual empirical history of Latin American interstate relations with the correctly specified causal variables offered by the various theories of international relations.
In Latin America international affairs are currently being considered from a perspective that doesn’t use theoretical instruments from other academic fields, whether from American, English, French, or other schools. Our aim is to emphasize recent contributions to the discipline, specifically Latin American ones. The spirit behind this line of analysis is to approach the study of international relations from the perspective of the region itself, because the goals and interests of its countries within the framework of world politics are not a struggle for power. This effort doesn’t seek to disrespect or ignore the importance of American theorizing. This compilation contains an elaboration of concepts that do not have any theoretical pretension of universality. Its only goal is to help understand how Latin American countries react to the contemporary dynamics of international affairs.

Political Science accounts of international politics downplay the role of political leaders, and a survey of major journals reveals that fewer than 3% of all articles focus on leaders. This is in stark contrast to public discourse about politics, where leadership influence over events is regarded as a given.
This article suggests that, at a minimum, leaders occupy a space in fully specified chains of causality as the aggregators of material and ideational forces, and the transmitters of those forces into authoritative political action. Further, on occasion a more important role is played by the leader: as a crucial causal variable aggregating material and ideational energies in an idiosyncratic fashion and thereby shaping decisions and outcomes.
The majority of the article is devoted to surveying the comparatively small literature on political leaders within International Relations scholarship. The article concludes by inviting our colleagues to be receptive to the idiosyncrasies, as well as the regularities, of statespersonship.
Classic accounts of the relationship between leadership and public administration used to be straightforward: Political officials exercise leadership in terms of providing direction to government, and administrations implement decisions made by those leaders. Over the past decades, however, both scholarly notions and empirical manifestations of leadership and administration have undergone substantive change. While the political leadership literature continues to be more interested in such aspects as goal identification and definition, and the ways and means by which leaders manage to garner and maintain support for their agendas, the crucial importance of implementation in terms of leadership effectiveness has been explicitly acknowledged since the seminal work of James MacGregor Burns who famously defined leadership as “real, intended social change.” Conversely, public administration scholars have discovered the role of bureaucrats in the leadership process as important subfields of public administration.
To some considerable extent, these reorientations in the political study of leadership and administration have been driven by empirical developments in the real world of leaders and administrators. In many of the established democracies, political leaders have come to realize the importance of administrative resources, and in some contexts, such as in the United States, it seems justified to speak of particular administration-centered approaches to, and strategies of, executive leadership. At the same time, large-scale reforms of the public sector have fundamentally altered the role of bureaucrats in the leadership process. While individual top civil servants, especially (but not only) in Westminster systems, have always exercised some leadership, New Public Management reforms designed to increase the efficiency of the public sector extended leadership roles across the bureaucracy. The relationship between political leaders and bureaucrats continues to display major differences between countries, yet politicization of the civil service in its various forms marks a strong cross-national trend. In some countries, the proliferation of special advisers stands out as a more specific element of change with important implications for the evolving nature of executive leadership.
Such differences between countries notwithstanding, a broad empirical inquiry suggests that the developments in the political and administrative parts of the executive branch in many major democracies are marked by divergent dynamics: While there is a notable trend within the political core executive to centralize power with the chief executive (prominently referred to as “presidentialization” by some authors), the public bureaucracy of many developed countries has experienced a continuous dispersion of leadership roles. The implications of these ongoing changes have remained understudied and deserve further scholarly attention. However, alongside a host of conceptual and methodological issues, perhaps the most difficult and complex challenges to leadership and administration, both for political science and politics itself, relate to processes of internationalization and globalization.

One of the ways that citizens and elites orient themselves to politics is in reference to a Left-Right vocabulary. Left and Right, respectively, refer to a specific set of progressive and conservative policy preferences and political goals. Thus, Left-Right becomes a framework for positioning oneself, political figures, and political parties into a common framework. Most citizens identify themselves in Left-Right terms and their distribution of these orientations vary across nations. These orientations arise both from long-term societal influences and from the short-term issues of the day. Most people also place political parties in Left-Right terms. This leads citizens to use Left-Right comparisons as an important factor in their voting choice, although this impact varies considerably across nations. Most parties attract voters that broadly share their Left-Right orientations.
