Transboundary haze pollution affects about half of the countries in Southeast Asia with varied intensities on an almost annual basis. Haze not only affects visibility, but also causes widespread health problems, transportation disruptions, and other socioeconomic issues. This haze, and the fires that cause it, has been a key topic for environmental politics research in the region since the late 1990s. This has largely been driven by one overarching objective: how to prevent haze from returning in the following years. However, conditions on the ground (mostly in Indonesia and in the larger Southeast Asian region) have been changing and evolving drastically. This has resulted in a very dynamic research agenda that has to keep up with these changes.
Within the context of environmental politics, fires and haze can be viewed through the broad lens of national interest. There is a strong link between the severity of haze and the burgeoning agribusiness sector in the region: that of oil palm in particular. Oil palm is a very important crop in the region, with Indonesia and Malaysia making up almost 90% of total global palm oil output. Hence, national and business interest theories have often been used as a framework for research in this area, with commercial oil palm plantations often being the unit of analysis. This includes research by this author, using the patronage politics framework. However, this has been called to question lately as these plantations face increasing market pressure to act more sustainably. A new group of actors that have since been highlighted are smallholders, either independent or in contract with larger plantations. There is potentially much to be uncovered with regard to the relationships between smallholders and commercial plantations, and how this affects patterns of fire use and global sustainability issues.
Related to this is the ever-evolving collection of local, regional, and national policies (and related enforcement issues) over land and fire use in Indonesia. One key area of contention is the use of peatlands. Fires on peat produce the thick, sooty smoke that travels across national boundaries, and are notoriously hard to put out. Political research in this area is heavily framed by a tough debate between the scientific community and socioeconomic concerns. While peatlands play an important role in the global climate change balance, at the same time, these peat areas face immense pressure for development fueled by the scarcity of land.
The regional context has also been an important theme for haze research. Haze primarily affects the Southern Southeast Asian subregion. And the major players of the palm oil sector also come from this region. The Indonesian palm oil sector is a vibrant combination of Malaysian, Singaporean, and local companies. And ASEAN has been the hub of cooperation and mitigation activities over haze. Hence, many scholars have searched for answers at the regional level. However, new national developments like Singapore’s Transboundary Haze Pollution Act suggest that countries may be losing confidence with regional efforts, which may be an indicator for future directions for solutions as well.

Logical models and statistical techniques have been used for measuring political and institutional variables, quantifying and explaining the relationships between them, testing theories, and evaluating institutional and policy alternatives. A number of cumulative and complementary findings refer to major institutional features of a political process of decision-making: from the size of the assembly to the territorial structure of the country, the electoral system, the number of parties in the assembly and in the government, the government’s duration, and the degree of policy instability. Mathematical equations based on sound theory are validated by empirical tests and can predict precise observations.
Sociological institutionalism is part of the larger group of new institutionalisms, which share the basic understanding that institutions matter in social processes. Opposing a more descriptive, “old” institutionalism and a rational-choice version of institutionalism, which defends the idea that actors have the option to choose independently from a large number of attitudes, sociological institutionalists introduced the notion of logic of appropriateness, influenced by a specific strand of the sociology of organizations. This understanding, however, led to limits in the explicatory force of the approach: institutional change, as well as continued conflict and differentiated power relations among actors, could not be explained well. More recent approaches that took sociological institutionalist assumptions very seriously offered a series of possible solutions to those difficulties. While elements of rationality and power exist implicitly in different conceptualizations of sociological institutionalism, these authors explicitly brought together both actors’ rational behavior and their embeddedness in broad institutional frameworks through concentrating on the power relations that exist among agents.
The historical evolution of the right to vote offers three observations. First, almost all groups have seen their voting rights challenged at some point in time, and almost all political movements have sought to exclude some other group from voting. Second, reforms towards suffrage extension are varied—from the direct introduction of universal (male) suffrage to a trickle down process of enfranchising a small group at a time. Third, the history of franchise extension is a history of expansions and contractions.
Much of the literature on the evolution of the right to vote builds on the following question: Why would a ruling elite decide to extend the suffrage to excluded groups who have different interests in the level of redistribution and the provision of public goods? Two competing theories dominate the debate: Bottom-up or demand theories emphasizing the role of revolutionary threats, and top-down or supply theories, explaining franchise extensions as the outcome of the strategic interactions of those in power and elites in the democratic opposition.
A second question addresses the choice of a particular path of franchise extension, asking what explains different strategies and, in particular, the role of their accompanying institutional reforms.
In contrast to the literature on the inclusion of the lower classes, women’s suffrage has been traditionally presented as the conquest of the suffragette movement. Current research, however, departs from this exceptionalism of female suffrage and shows certain consensus in explaining women’s suffrage as a political calculus, in which men willingly extend the franchise when they expect to benefit from it. Arguments differ though in the specific mechanisms that explain the political calculus.
Finally, the literature on compulsory voting addresses the estimations of its impact on turnout; whether it translates into more efficient campaigning, improved legitimacy, and better representativity; and ultimately its effects on policies.

We summarize the formal theoretical literature on Supreme Court decision-making. We focus on two core questions: What does the Supreme Court of the United States do, and how can one model those actions; and, what do the justices of the Supreme Court want, and how can one model those preferences? Given the current state of play in judicial studies, these questions then direct this survey mostly to so-called separation of powers (SOP) models, and to studies of a multi-member (“collegial”) court employing the Supreme Court’s very distinctive and highly unusual voting rule.
The survey makes four main points. First, it sets out a new taxonomy that unifies much of the literature by linking judicial actions, modeling conventions, and the treatment of the status quo. In addition, the taxonomy identifies some models that employ inconsistent assumptions about Supreme Court actions and consequences. Second, the discussion of judicial preferences clarifies the links between judicial actions and judicial preferences. It highlights the relationships between preferences over dispositions, preferences over rules, and preferences over social outcomes. And, it explicates the difference between consequential and expressive preferences. Third, the survey delineates the separate strands of SOP models. It suggests new possibilities for this seemingly well-explored line of inquiry. Fourth, the discussion of voting emphasizes the peculiar characteristics of the Supreme Court’s voting rule. The survey maps the movement from early models that ignored the special features of this rule, to more recent ones that embrace its features and explore the resulting (and unusual) incentive effects.

Typologies are a central tool of comparative analysis in the social sciences. Typologies identify common patterns in the relationships among elements of media systems and wider social systems, and serve to generate research questions about why particular patterns occur in particular systems, why particular cases may deviate from common patterns, and what the consequences of these patterns may be. They are important for specifying the context within which particular processes operate, and therefore for identifying possible system-level causes, specifying the scope of applicability of theories, and assessing the validity of measurements across systems. Typologies of media systems date to the publication of Four Theories of the Press, which proposed a typology of authoritarian, libertarian, social responsibility and Soviet Communist media systems. Hallin and Mancini’s typology of media systems in Western Europe and North America has influenced most recent work in comparative analysis of media systems. Hallin and Mancini proposed three models differentiated on the basis of four clusters of variables: the development of media markets; the degree and forms of political parallelism; journalistic professionalism; and the role of the state. Much recent research has been devoted to operationalizing these dimensions of comparison, and a number of revisions of Hallin and Mancini’s model and proposals for alternative approaches have been proposed. Researchers have also begun efforts to develop typologies including media systems outside of Western Europe and North America.
Rational choice theory may seem like a separate theoretical approach with its own forbidding mathematics. However, the central assumptions of rational choice theory are very similar to those in mainstream political behavior and even interpretive sociology. Indeed, many of the statistical methods used in empirical political behavior assume axiomatic models of voter choice. When we consider individual voting behavior, the contribution of rational choice has been to formalize what empirical political scientists do anyway, and provide some new tools. However, it is when we consider collective voting choice—what elections mean and what kind of policy outcomes result—that rational choice leads to new, counterintuitive insights. Rational choice also has a normative dimension. Without voter rationality the traditional understanding of democracy as popular choice makes little sense.
