All governments require revenue, and domestic taxes are the primary means for generating it. Yet both the size and shape of taxation vary significantly across countries and have been transformed over time. What explains variation in domestic taxation? To answer this question, recent scholarship on taxation has focused on the politics of taxation as a tool for redistribution. This has led to a wide body of research on the fiscal impact of taxation and on the introduction, evolution, and variation in direct and progressive tax regimes, particularly the income tax. Yet the focus on taxation as a redistributive tool yields a puzzle, as more progressive tax systems tend to be found where redistribution is in fact the lowest. Explanations of this paradox often center on the impossibility of high and progressive taxes on capital in the context of international economic integration. Not as well studied are taxes other than the taxation of income, and the deliberate politics of nonfiscal, regulatory, and incentive effects of different tax choices. Methodologically, problems of endogeneity are ubiquitous in the study of tax policy choices, but more sophisticated experimental work is well underway in research on individual preferences for taxation.
“Evidence-based policy making” (EBPM) has become a popular term to describe the need for more scientific and less ideological policy making. Some compare it to “evidence-based medicine,” which describes moves to produce evidence, using commonly-held scientific principles regarding a hierarchy of evidence, which can directly inform practice. Policy making is different: there is less agreement on what counts as good evidence, and more things to consider when responding to evidence.
Our awareness of these differences between science and policy are not new. Current debates resemble a postwar policy science agenda, to produce more scientific and “rational” policy analysis, which faced major empirical and normative obstacles: the world is not that simple, and an overly technocratic approach to policy undermines much-needed political debate. To understand modern discussions of EBPM, key insights from previous discussions must be considered: policy making is both “rational” and “irrational”; it takes place in complex policy environments or systems, whose properties should be understood in some depth; and it can and should not be driven by “the evidence” alone.
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.

International trade and state efforts to liberalize or restrict trade generate very contentious politics. Trade creates winners and losers at the individual level, firm level, industry level, national level, and even regional level. It also generates conflict among transnational social groups, such as environmental advocacy organizations, human rights organizations, and transnational business alliances. Because of this complexity of the politics of international trade, scholars of international political economy (IPE) can focus on different levels of analysis and a variety of stages of the political decision-making process. Scholars agree that not only societal preferences but collective action problems, domestic institutions, and international factors all affect trade politics and policy outcomes. These aspects of trade politics together form the key influences on trade policy and whether it is liberal or protectionist in nature.
Societal preferences constitute the initial inputs into the trade policy-making process. Understanding how different groups of economic actors within society win or lose from trade liberalization or protection is the first step toward understanding trade politics and trade policy outcomes. Once societal trade preferences are formed, they must be aggregated into cohesive pressure groups or grass-roots movements whose purpose is to influence trade policy. This is easier for some groups of actors to achieve than others. In lobbying government actors on policy, interest groups find that domestic institutions play an important role translating societal inputs into policy outputs. Policy-making institutions vary in the degree to which they are susceptible to special-interest lobbying versus the preferences of broader societal coalitions, and electoral rules and party structures also affect policy outcomes, with certain configurations creating a bias toward more protectionism or liberalization.
In addition to these domestic-level influences on trade policy, IPE scholars have extensively studied the ways that international factors also affect trade policy outcomes such as the extent of liberalization and the content of what is liberalized (e.g., manufactures versus agricultural goods versus services). International factors such as the distribution of power, the character of international institutions and trade agreements (e.g., multilateral versus bilateral), transnational civil society and diffusion processes may be thought of as inputs into the policy-making process as well. Systemic conditions may constrain the types of policies that governments can adopt, or they may open the door to a range of possible policy outcomes that are nevertheless limited by the preferences of domestic societal actors.

Language policies in sub-Saharan African nations emerge out of specific political, historical, socioeconomic, and linguistic conditions. Education plays a crucial role for all spheres of language policy. Policies either upgrade or downgrade indigenous languages through their application at various educational institutions. The most significant example is the selection of the language(s) used as languages of learning and teaching at higher-education institutions. The region’s colonial history also influences the language policies of the independent African states. Language policy in Senegal is an example of a francophone country focusing on a linguistic assimilation policy in which minor reforms in favor of indigenous languages have taken place. Rwanda’s language policy is unique as the former francophone nation now uses English as an exoglossic language in a type of hybrid language policy. Botswana is an example of an anglophone country that follows a language policy that is dominated by a very close connection to the notion of nation-building through its concentration on a single language, Setswana, alongside English. Tanzania is an anglophone African country whose policy focuses on Kiswahili, which is one of the very few indigenous and endoglossic languages. Kiswahili is broadly used in Tanzanian educational institutions until the tertiary level, but its use as medium of instruction focuses on the primary level. South Africa demonstrates the very close relationship between general political decisions and language policy and vice versa. Language policy decisions are never neutral and are influenced by the politics of a specific country. As a result, individual and societal language attitudes influence language policies. In addition to this, the overt and official language policy on a macro level may differ from the implementation of such policies on a micro level. At the micro level, practice can include covert language practices by various stakeholders.
The United Nations system has been a major global site of political and legal contestation for LGBTQI human rights. However, the lack of consensus has led to major divisions within the UN’s political institutions. The independent human rights institutions that do exist within the UN system have been more progressive in advancing LGBTQI issues.

Charismatic Pentecostalism constitutes perhaps the most important contemporary movement in sub-Saharan Africa, combining extremely rapid growth with an informal political presence. The movement has expanded in Africa by bringing traditional spirituality into a modern setting, offering social and economic hope to both the upwardly mobile and the destitute. Despite having minority status, its messages of pending prosperity and spiritual warfare, and its astute exploitation of mass media, have positioned the Charismatic Pentecostal movement to exert important if informal influence on politics in the region. It is reshaping the channels through which resources flow from Big Men to their followers; it is implicating new and different international actors; and it is allowing followers to live fully within the church through the provision of social services. Perhaps most importantly, the movement has introduced language of national identity—of good and evil, and Christian nations—that captivates just as it divides. Its potential to influence the formal politics of institutions and parties is limited by the absence of organizational hierarchy and a central focus on remaking the individual rather than addressing social injustices. Nevertheless, by informal means, the movement has “Pentecostalized” politics in many African countries.
National broadcasters are a standard feature across Africa. Set up by colonial regimes, they dominate media landscapes with their unrivaled geographic reach. Radio continues to be the main—and often only—source of information outside urban centers, where commercial media struggle to survive and illiteracy remains a challenge. Although access to new media has risen exponentially, use of mobile technology continues to be prohibitively expensive.
Some national broadcasters are official state broadcasters: owned, run, and editorially controlled by government. However, many claim to be public broadcasters. By definition, these are accountable to the public rather than the government of the day: accessible to a universal audience, inclusive of a wide range of views; and fair, balanced, and independent in their journalism. This aspiration is reflected in national and supranational policy such as the African Charter on Broadcasting and the Declaration of Principles on Freedom of Expression in Africa.
In reality, these broadcasters lack de jure independence, the basic condition for them to be considered “public.” They are, in law and in practice, state broadcasters—owed to a range of historical, social, financial, and political determinants despite attempts by journalists and civil society to change this. Principally, the political will has been lacking—in colonial as well as postcolonial elites—to relinquish control of newsrooms and open up space for dissent.
There is one exception: the South African Broadcasting Corporation was granted de jure independence following apartheid and enjoys unrivaled (though contested) legal guarantees and journalistic freedom. Its ongoing difficulties to fully meet its public broadcasting mandate despite this relatively conducive environment demonstrate that de jure independence is a necessary but not sufficient condition for successful broadcasting transformation, and that organizational culture is an important variable to be taken into account.

Both trade and climate change policies affect the international competitiveness of carbon-intensive industries. This suggests that policy changes in one area may affect politics in the other. Does openness to international trade affect climate change politics? Do climate change policies affect the politics of trade? Does formally linking trade and climate policies via trade sanctions affect the prospects for cooperation in each domain? There are good theoretical reasons to believe that the answer to these questions is yes. Theoretically, each set of policies should affect the other, but these interactions could either encourage or discourage trade and climate cooperation. How trade and climate politics interact is thus an empirical question. Empirically, the overall picture is of a nascent but promising field of research. Extant studies provide indirect tests and suggestive evidence, but little in the way of firm conclusions. Only one point emerges clearly: progress in this area will require more and better data on national climate policies.

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.

Since the inception of air power as a technological innovation, both scholars and military practitioners have given much thought to the use of aircraft during conflict settings and how it might influence both outcomes and the way states fight. Air power can greatly expand the targets that are available to an attacker, making it so that it is not necessary to get through the opponent’s military defenses in order to target their population centers or other centers of gravity. At the same time, air power can reduce the costs of the attacker, allowing them to potentially achieve their coercive aims without necessarily incurring the costs, both financial and in terms of casualties, that a ground invasion can entail.
Though the writing on air power from the theoretical and military strategic perspectives is vast and informative, there is also a relatively new research agenda focused on empirical work on air power within the field of international relations. This work has expanded in the last 20 years but still has much room for growth. Traditionally, air power has been thought of as a tool used by major powers, the states with the largest militaries and also the most economic resources. Work on air power has found that particularly major powers that are sensitive to incurring costs through military interventions, such as democratic powers, are prone to using air power. The reason for this is that these states perceive air power as a low-cost and low-commitment way to engage in international coercion. More recent work on air power supports some of these expectations, but challenges others.
As scholars collect new data on coercive episodes of aerial bombing, evidence shows that air power is also used by powerful autocracies, and that as technologies develop, minor powers may also become involved in the use of coercive air power, particularly when it comes to the use of remotely piloted aircraft (drones). New research has also engaged the question of how different aerial strategies can affect the duration and outcomes of aerial campaigns. Recent work moves beyond traditional distinctions between punishment and denial strategies and considers cases in which mixed strategies are used, as well as distinguishing between how discriminate the cases of bombing either civilian or military targets are. In addition, new research shows that the use of air power during intrastate conflict and against non-state actors such as insurgent groups or terrorist organizations is prevalent and a topic that should be studied by political scientists.

How well do people around the world understand democracy? Do they support democracy with an informed understanding of what it is? To address these questions, which have largely been overlooked in the literature on democratization, the World Values Survey and three regional barometer surveys are analyzed according to a two-dimensional notion of democratic knowledge. Their analyses reveal that a vast majority of global citizenries especially in post-authoritarian and authoritarian countries are either uninformed or misinformed about the fundamental characteristics of democracy and its alternatives. These findings contradict the popular theses that democracy is emerging as a universal value and it is also becoming the universally preferred system of government. For much of the world today, democracy represents little more than an appealing political symbol that still retains authoritarian practices.

Most of the world has experienced a revolutionary and unprecedented development over the course of the last century and especially since the end of the Second World War: significant population aging. By any standard measure—median age, the number of 60- or 65-year-olds and over as a percentage of a population, or old-age dependency ratios (the ratio of seniors to working-age adults), most of the world is significantly older today than in the middle of the 20th century, and the trend is accelerating.
The world’s great powers have not been immune to this trend. To the contrary, many of these countries have been leading the way, aging faster and to a greater extent than most other countries. By 2050, the median age of China, France, Germany, Japan, Russia, the United Kingdom, and the United States will be at least 40. Germany and Japan are currently two of the oldest countries in the world, and China is likely aging faster than any other country in history.
How is the near worldwide phenomenon of population aging likely to affect international relations (IR)? Most scholars who have examined this issue have linked the potential effects created by aging to established IR theories. Most analyses that have developed around the issue of aging, in other words, have not created new theoretical approaches to the study of international politics. They have instead argued that aging is likely to affect key variables associated with existing IR theories, which will then tend to generate particular outcomes based on these theories’ predictions. The IR theories that studies of populating aging have most frequently tied into include ones from realist, diversionary war, and constructivist research programs. Many of the arguments that link the effects of aging to these theories reach opposite conclusions, with some predicting a much higher probability of international conflict due to aging, others the reverse. There are, however, very few empirical analyses that test these competing hypotheses, largely because aging is such a new phenomenon.

At the conceptual level, populism and Euroskepticism are both closely related and inherently distinct. Notably, populism is a general set of ideas about the functioning of democracy, while Euroskepticism concerns a position toward a more concrete political issue (European integration). When focusing on the political supply side (political parties) as well as the demand side (citizens), populism and Euroskepticism can often be observed in tandem. In practice, many populist parties are Euroskeptic, and many Euroskeptic parties are populist. Euroskepticism and populism can typically be found at the ideological fringes of party systems, in particular among parties with radical left socioeconomic positions on the one hand and radical right sociocultural positions on the other. While little is known about the relationship between populist and Euroskeptic attitudes among citizens, it is clear that such attitudes contribute to support for populist and Euroskeptic parties. Moreover, preliminary analyses indicate that at the level of voters, populist and Euroskeptic attitudes often coincide. Future studies (considering both the supply and the demand sides) should focus in greater depth on how the two concepts are related and how they interact in practice.
The topic of populism in foreign policy is receiving growing attention in academic and public discourse as populist parties and movements proliferate around the world. Yet foreign policy analysis (FPA) scholars interested in the role of populism in foreign policy have to deal with a concept that is notoriously slippery and contested.
The existing literature on populism and foreign policy has already offered interesting insights. Focused primarily on Europe, it usually applies the conceptualization of populism as a thin-centered ideology that attaches to thicker ideological traditions and reformulates them in terms of the elite-people divide. Following this conceptualization (that is today the dominant framework for the comparative analysis of populism, particularly in Europe), this literature argues that populist parties of the right have foreign policy positions that reflect their nativism, opposition to immigration, focus on national sovereignty, and rejection of economic and cultural globalization. Populist parties of the left on the other hand reject in their foreign policy positions neo-liberalism and open markets. Together, European populist parties of all persuasions are Eurosceptic, anti-American, and usually pro-Putin’s Russia.
Highlighted are the breadth of critical and discursive approaches on populism that scholars of populism and foreign policy can use, particularly because they have been applied successfully to cases outside of Europe, where populists have long held political power and have influenced foreign policy in practice. Such conceptualizations commonly view populism as a reaction to crises of political representation engendered by dislocations caused by globalization and other shifts in international politics. These dislocations will take different forms, but populism in the West and populism in the Global South can be seen, despite more specific differences of outlook, at the very least as a specific type of reaction to concurrent political and economic crises in a rapidly denationalized and deterritorialized world. In this context, most populist foreign policies reflect a preoccupation with popular sovereignty and unmediated projection of popular demands and national interests outside of established processes of global governance. Populists will also tend to perceive and analyze foreign policy issues through the lens of the elite-underdog opposition.
Populism is commonly associated or conflated with nationalism (especially in the case of the European radical right) and isolationism, but in practice this does not always have to be the case. The “people” for whom populists speak in international affairs can very well transcend national borders, as evidenced, for example, in the foreign policies of Hugo Chavez and Mahmud Ahmadinejad, who aimed to represent transnational constituencies like the Global South, the Islamic world, the world poor, etc. And while populists generally eschew commitments to broader milieu goals of the international system, they can still engage with foreign affairs if they see immediate material benefits. The same goes for trade: populists (particularly in the United States) are seen usually as ideological protectionists, but most often they do not mind striking trade deals if these favor their interests (see, e.g., Donald Trump’s discourse on this issue).
In terms of theoretical and methodological advancements, foreign policy scholars interested in populism are urged to embrace the large variety of conceptual approaches on populism (ideological, critical, discursive) and to build on the growing literature on cross-regional comparison of populist politics, something particularly pertinent in a world characterized by the presence and prominence of populism in almost all world regions.
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.
Since roughly the turn of the millennium, there has been a growing literature discussing the potential characteristics of African Developmental States—if they exists and in that case how they should be defined and exemplified. The basis for this literature has been the experience of the trajectory for sustained economic growth in Pacific Asia. But it has expanded into a broader discussion about the role of authoritarian regimes versus democratic states, outcomes versus intentions, and overall ambitions versus concrete strategies. The most common suggestions for African counterparts have been the two growth miracles—Botswana and Mauritius, although other countries such as South Africa, Rwanda, and Ethiopia have also been on the agenda. The original Developmental State concept entails a specific type of social engineering that has so far been rare in Africa: a legitimate state leading a planned capitalist economy with a competent and autonomous bureaucracy spearheading industrialization efforts in profound collaboration with the private sector. With such a narrow definition, it is only the development pathway of Mauritius that can be said to fit the criteria while Botswana falls short due to its weak industrialization efforts, longstanding interconnectedness between the bureaucracy, political power, and cattle elite, and lack of dynamic cooperation between the state and private-sector entrepreneurial groups. Whether or not we will see more examples of African countries following the specific Developmental State trajectory or if they will create alternative development paths to economic diversification, transformation, and prosperity remains to be seen.

Postcolonial theory has been embraced and critiqued by various scholars since the 1980s. Central to the field of postcolonial studies is the examination of colonial episteme and discourse, European racism, and imperial dominance. Broadly, postcolonialism analyzes the effects, and enduring legacies, of colonialism and disavows Eurocentric master-narratives. Postcolonial ideas have been significant to several academic disciplines, largely those in the humanities and social sciences, such as cultural and literary studies, anthropology, political science, history, development studies, geography, urban studies, and gender and sexuality studies. The key scholars that are connected to postcolonial theory, Edward Said, Homi Bhabha, and Gayatri Spivak, have been critiqued for grounding their work in the Western theories of postmodernism and poststructuralism. Given the predominant association of these three scholars to postcolonial theory, Africanists have argued that postcolonial theory is dismissive of African theorizing. Moreover, some scholars have noted that Africanists have hesitated to use postcolonial theory because it is too discursive and has limited applicability to material reality. As such, the relevancy of postcolonial theory to Africa has been a repetitive question for decades. Despite this line of questioning, some scholars have posited that there are African thinkers and activists who are intellectual antecedents to the postcolonial thought that emerged in the 1980s and 1990s. Additionally, other Africanist scholars have engaged with the colonial discursive construction of African subjectivities and societies as inferior. These engagements have been particularly salient in women and gender studies, urban studies and studies of identity and global belonging.
Religion was a relatively overlooked factor in the study of political science until the 21st century. Even when the focus on religion increased in the aftermath of 9/11, a majority of the scholarship still dealt with religion and violence. “Religion and peace” has arguably been a less popular topic, yet there is still a vibrant literature that has contributed to our understanding of religion and social dynamics, especially given the significant number of religiously inspired organizations that are active in postconflict processes, such as Network of Engaged Buddhists, Sant’Egidio, and American Jewish World Service. Religion can play a critical role in conflict resolution and negotiation, especially in settings where secular approaches fall short of resolving the tensions, and where religious actors are seen as more neutral than the political actors. Peacebuilding literature has also recognized the importance of religion. Every religious tradition has its own sources of nonviolence within itself, and under the right conditions, these sources can help with reconciliation, peacebuilding, and transitional justice. At the same time, involvement of religious actors in postconflict processes poses its own challenges. Religious actors are rarely fully neutral, their assistance usually comes with conditions attached, and their involvement in political processes can undermine their moral authority. In addition, there are religious leaders who work against reconciliation to protect their own status in conflict settings. Recognizing that it is difficult to measure the effectiveness of faith-inspired initiatives, more scholarship is needed to explore the dynamics of religious initiatives in postconflict processes. There are gaps especially when it comes to non-Christian actors’ involvement in peace processes, and how the faith-inspired initiatives of individuals differ from those of religious institutions and organizations.
Lebanon is a multisectarian society of four million people, divided among eighteen sectarian affiliations, many of which are highly salient in Lebanese society. The country experienced a complex, multifaceted civil conflict from 1975 to 1990, the aftermath of which continues to shape political interaction in the country. Sectarian identity has evolved, both before as well as after the civil conflict, shaped by clientelism, individual identities, and Islamist political movements. Despite years of conflict, identity in post-war Lebanon has remained fluid, and while sect is still a relevant identity marker, it is neither as deterministic nor as linked to religious piety as outside observers may expect. Research shows that Lebanese citizens face pressures to conform to sectarian beliefs due to the control that sectarian political parties have over goods distribution, but, at the same time, conforming to the sectarian democratic system may moderate the absolutist claims of Islamist political movements, especially Hizbollah. Despite the institutional and demographic idiosyncrasies of the Lebanese political system, each of these findings do much to inform outside literature on religion and post-conflict processes, along with tangential work on clientelism, the role of identity and politics and Islamic politics. However, there is still much to be done. Researchers should devote more attention to the growing backlash against sectarianism among popular movements within Lebanon and do more to explore the links between clientelism and sectarian identity in more precise and greater detail.
