How do structural transformations in advanced capitalist economies affect the political demands of individuals and interest groups? My research examines the intricate relationship among occupation, social identity, and political preferences in governing macro-societal transformations like globalization, automation, and climate change.

For my dissertation project titled Politics Navigating Macroeconomic Transformations: Labor Migration and Automation in Western Europe, I focus on labor migration and automation in Western Europe, which bring economic benefits and job-displacing concerns. The project examines how both double-edged transformations affect public support for social welfare policies, exploring public opinion and politics among business associations, labor unions, and political parties.

I emphasize the key role of occupation as a micro-foundation of economic interest that shapes political choices. Additionally, I investigate how social identities (e.g., race and gender), organizational affiliations (e.g., union membership), and informational cues (e.g., educating policy implications) influence an individual’s political decisions. My research sheds light on the multifaceted nature of political decision-making processes and preferences by unraveling the dynamics between these factors and occupation, especially amidst significant societal changes.

Saving His Job, Not Hers: Selective Protection in Automation-Driven Job Loss (Soohyun Cho and Jaewook Lee)

– Awarded SASE 2025 Early Career Workshop
Abstract

Recent advances in automation have raised concerns about job displacement and increased interest in social protection policies. However, public support for such measures is not uniformly distributed across cases of job loss. This study argues that gender norms, rather than economic vulnerability alone, explain support for social protection in response to automation-driven layoffs. Using a survey experiment in South Korea, we show that automation-driven job loss increases support for an ex-ante protective measure (e.g., Automation Tax) only when male workers are affected. This selective protection reflects the male-breadwinner model, which views male labor as more essential to household income and male job loss as more socially disruptive. The disparity in social policy preferences by the laid-off worker’s gender profile is pronounced among individuals who hold sexist attitudes. Our findings reveal how gendered beliefs about labor value shape social protection preferences, highlighting identity-based biases in responses to economic change.

Green Backlash or Distributive Discontent? Welfare State Satisfaction and Public Support for Carbon Taxation (Jaewook Lee and Marcello Natili)

Abstract

The climate crisis is an urgent challenge, yet public support for fossil fuel taxation remains low. Existing research highlights how material interests, such as concerns about the regressive nature of consumption taxes like fuel taxes, contribute significantly to this limited support. This perspective aligns with the literature on the emerging ‘eco-social divide,’ which highlights tensions between environmental and equity concerns, yet potential synergies remain understudied. While social policies may ease resistance by protecting displaced workers, we know little about whether they actually do. We examine what drives public support for a fossil fuel tax designed to reduce carbon emissions but likely to displace workers, focusing on the mediating role of the welfare state. Drawing on original survey data from the ‘Eco-Social’ UniMi project (10,500 respondents across seven European countries), we find that income anxiety and dissatisfaction with national social policies significantly reduce support for fossil fuel taxation. Moreover, individuals facing high employment risk are less supportive of carbon taxation when dissatisfied with social policies, but their support increases as satisfaction with the welfare state improves. These findings suggest that confidence in the welfare state can offset economic concerns driving opposition to climate policy, thereby easing the ‘green backlash.’

Teaching Machines to Read Occupations: Introducing the OPUS Dataset of Occupational Partisanship (Scott Patterson, Krzysztof Pelc, and Jaewook Lee)

Abstract

Many of the richest social data come as open-ended, write-in responses. Occupational data are a prime example, yet the difficulty of coding such free-text entries has long limited research. We address this challenge by fine-tuning a large language model (LLM) to classify millions of write-in occupation fields into a standardized taxonomy. Treating classification as a text-generation task, we supplement standard occupational descriptions with a large corpus of alternative job titles, generating synthetic data for infrequent occupations. The resulting classifier matches or exceeds the accuracy of the US government’s benchmark tool, especially in the long tail of rare occupations. We use this method to construct the Occupational Partisanship in the United States (OPUS) dataset, which assigns partisan scores to nearly all occupations in the O*NET standard classification. Two findings illustrate its potential: (i) occupation predicts partisan identity as well as, or better than, county of residence; and (ii) majority-female occupations lean consistently Democratic. Our approach provides a low-cost, generalizable framework for classifying write-in data and a new empirical lens on the political structure of the American labor market.

Automation, Immigration, and the Politics of Displacement Legitimacy: Institutional Legacies and Public Opinion in Comparative Perspective (Jaewook Lee)

Abstract

Do citizens judge job displacement differently depending on whether it is driven by automation or immigration, and does institutional context shape these evaluations? This paper develops an institutional-conditioning framework arguing that coordinated industrial relations create shared legitimacy frames through which publics interpret economic adjustment. An institutional analysis of the UK and Sweden shows that Britain’s weak unions and voluntarist bargaining enabled employers to rely on low-cost migrant labor, whereas Sweden’s stronger labor coordination limited dependence on migration and promoted technology-oriented adjustment through retraining and social partnership. A survey experiment (n = 1,050) finds that Swedish respondents distinguish sharply between the two sources—viewing immigration-led displacement as less legitimate and more deserving of regulation than automation-led displacement—while British respondents show no such distinction. Exploratory analysis suggests individual union membership is associated with more favorable evaluations of automation-led displacement but not immigration-led displacement. Taken together, the findings suggest that institutions of industrial relations shape both how economies adjust to labor market pressures and how citizens assign legitimacy to economic transformation.

The Electoral Costs of Computing: Data Centers and the Politics of Environmental Footprint
– Awarded APSA 2025 Centennial Center Research Grant

This project examines how the rapid growth of AI data centers—major consumers of electricity and water—affects electoral outcomes and public attitudes toward climate policy. Combining US county-level data analysis with an original survey, it examines the electoral consequences of data center installation and identifies conditions under which the public demands tighter governance over computing infrastructure.

Uncertain Returns: Automation Risk and the Politics of Social Investment (with Jiyeong Jeon)

We argue that uncertainty about the effectiveness of reskilling in an age of rapid AI advancement drives workers to favor immediate compensation over long-term social investment. Using cross-national survey data, the study highlights how declining confidence in re-employment prospects under automation reshapes support for welfare policies.

European Competitiveness and Attitudes Towards EU Fiscal Integration (with Lars van Doorn and Olaf van Vliet)

This paper investigates how narratives about European economic competitiveness shape public preferences for EU-level fiscal integration. Through survey experiments across Europe, it shows that priming the need for building Europe-wide competitiveness increases support for fiscal coordination— especially among respondents in manufacturing sectors who are most likely to benefit from it.

When Growth Breeds Exclusion: Macroeconomic Prospects and Welfare Chauvinism in Europe (with Lars van Doorn and Olaf van Vliet)

Drawing on a novel survey experiment across thirteen European countries, this paper tests whether economic growth or decline affects exclusionary welfare preferences. We find that personal economic optimism can paradoxically heighten welfare chauvinism, especially among socioeconomically disadvantaged respondents.

Occupational Asymmetry in American Electoral Campaign Finance (with Scott Patterson)

This study uses machine-learning classification of Federal Election Commission contribution data to map occupational inequalities in campaign finance. It reveals that donations are overwhelmingly concentrated among high-income professionals, underscoring the occupational roots of political inequality in the United States.
