Research at the LKY School addresses real-world policy challenges and explores and advances theoretical concepts across four broad areas: Policy Studies, Public Management and Governance; Social Policy; International Relations and Global Governance; and Economic Development and Competitiveness.

Our research is supported by a variety of sources, including highly competitive external grants from local and international funders.

International Relations and Global Governance

Academics in this cluster study the power shifts taking place globally and in Asia and the implications of the shifts for regional and global security and stability.

Essays on Inequality in Policymaking and Human Behavior

Grant Period : Oct 2024 - Sep 2029

Faculty : Alessio ALBARELLO

I plan to analyze institutional structures in democratic systems and their effect on policymaking processes and outcomes, and how these structures and policies in turn affect how people behave. My research will span broadly, but it will also focus on immigration policy, and gender and politics. A few questions I plan to answer are:

- What are the conditions that favor immigrant integration in host societies?
- What are the political incentives and costs that parties and countries face in favoring or
hindering immigration?
- What are the factors that still prevent women to be equally represented in political institutions?
- How can women increase access to political positions?

The geographic scope will be broad, but it will also concentrate in the U.S., Europe, and East Asia. The primary mode of research employs secondary data analysis, survey and experimental methods, and archival work.

My work is highly relevant as it addresses two critical aspects of contemporary political inequality: citizenship and gender. Immigration has surged in recent decades, with foreign-born populations now comprising significant portions of many countries, such as 30% in Australia and Germany. This demographic shift has contributed to political realignment, with anti-globalization parties gaining traction as many populist voters express concerns about rapid changes in the cultural and ethnic makeup of their countries. Understanding the political consequences of immigration is crucial today, as it significantly influences policymaking, social cohesion, and economic policies in numerous nations worldwide.

Women's representation in politics is crucial both for normative reasons and for its impact on policy outcomes, yet achieving gender parity in political institutions remains one of the most persistent global inequalities. Despite their greater numbers, women face higher barriers to entry and advancement in political offices. Additionally, women's policy preferences are often penalized compared to those of men. Therefore, deepening our understanding of the causes of female under-representation in politics is essential for promoting policies that can help create a more egalitarian society.

The first project is a solo-authored monograph on how the democratic community and international organizations influence military humanitarian interventions. My proposal for this project, entitled Liberal Democratic Community and Humanitarian War, has already received a positive reception from the editor of Cambridge Elements: International Relation, a series edited by Jon Pevehouse (Vilas Distinguished Professor of Political Science at UW Madison, and previous editor of International Organization), who is a leader in my field, and so I have been invited to complete the manuscript and submit it for review.

The project will advance a major debate on why international organizations can influence global support for military foreign policy. Existing arguments focus on rational, material, and legal factors—political communities and international organizations (like the United Nations) can signal to people that a foreign policy will be successful, worth the costs, and legal under international law.

The second project is a set of papers in collaboration with Scott Williamson (Asst. Prof. University of Bocconi) and Eddy Yeung (Ph.D. Student, Emory) on international mass opinion on democracy. Given the global decline in the health of democratic governance, and criticisms of western-centric notions of democracy, our projects will present fresh data, using new techniques in experimental survey design, to shed new light on how citizens around the world think about democracy. It specifically will answer two questions: (1) how citizens around the world define “democracy”—e.g., emphasis on procedures, rules, elections, fair outcomes, participation, or something else—and (2) how they prioritize of democracy versus other aspects governance (e.g., prioritizing public health and safety vs the ability to participate in elections).

I study how Southeast Asians’ economic preferences affect their foreign policy preferences, especially security policy preferences, amidst China-US rivalry. The project has three components. The first is a traditional survey that uses canonical trade theories to predict individual’s security policy preferences. The second is specifically about choosing sides, where different trajectories of development in China and the US will be randomized in a conjoint experiment. The final component is a vignette experiment on a showdown between in the Taiwan Strait. Randomized are the predicted probabilities of US intervention. The goal is to assess how individuals wish their governments to respond.

My research explores the causes and consequences of public and elite opinion in international relations, focusing on how law, identity, and norms shape individual beliefs about foreign policy issues. The substantive domain of my inquiry covers the three major areas of the laws of war: jus ad bellum (the right to war, conflict initiation), jus in bello (wartime conduct), and jus post bellum (ending wars, transitional justice), but will also engage with issues relating to people’s beliefs about liberal democracy and a liberal world order. My geographic scope is global but will focus on the U.S., UK, and East Asia. The primary mode of research employs survey and experimental methods but will also engage with other approaches.

The significance of this research is twofold. Theoretically, international relations research has focused on interstate or system-level explanations for outcomes relating to warfare, rather than individual-level factors, which is the focus of my research. By examining variation across individuals, my research innovates by bringing in social psychology and behavioral economics to answer international relations questions. Empirically, I will bring new data to the field via original polling work, the most novel of them being of elite samples.

One of the most pressing foreign policy challenges Singapore and the rest of Southeast Asia face in the coming years is how to position themselves between the US and China as the geopolitical rivalry between the two superpowers intensifies. Like most of its Southeast Asian neighbours, Singapore would prefer not to have to choose between the two superpowers, but that position will become increasingly difficult to maintain as the US and China pressure states in the region to align with them. This project seeks to answer four key questions related to this strategic dilemma: What does it mean to choose (between the US and China)? How can we track the shifts in alignments of the countries of Southeast Asia over time? What explains their alignment choices? And what are the implications for Singapore, the superpowers, and the region?

Our project will bring together a group of scholars from the region and beyond to puzzle through, research, and answer these questions. The Co-PI of the project is Professor Joseph Liow (Comparative and International Politics, NTU), and our multidisciplinary team of collaborators include Professors Ang Cheng Guan (History, RSIS/NTU), Charlotte Setijadi (Anthropology, SMU), and Lu Xi (Economics, LKYSPP). Ten scholars will be invited to join the project as contributing authors: each will write a ten thousand world chapter on the ASEAN country of their expertise, documenting and analyzing the country’s alignment choices over time. These chapters, together with the Introduction and Conclusion written by the PIs, will constitute the major output—an edited volume aimed at a good University Press—of the project. Two Post-Doctoral Fellows—specialists in the international relations of Southeast Asia—will also be recruited to help organize and run the project, while they convert their dissertations into publications that address the themes of the project.

The findings of the project will add value to the local, regional, and international research landscape by clarifying the meaning of choice, devising techniques to measure it, and formulating hypotheses to explain it. In so doing, the project seeks to deepen our theoretical and empirical understandings of strategic alignments in a time of change, while providing policymakers with the requisite information and data to aid their decision-making.
