I am a Ph.D. candidate in Political Science at UC San Diego, in the fields of comparative politics and political methodology, with a specialization in computational social science. My research is in comparative and international political economy and in authoritarian politics, with China as its main case. I study how authoritarian regimes win public support and build state capacity, how citizens contest them, and how state-directed development shapes paths to democratization. I also study how external shocks, such as sanctions and trade disputes, affect domestic politics and economic institutions.

My dissertation asks why state ownership, once a socialist economic institution, has outlived the socialist world that built it. State-owned enterprises anchor the world’s second-largest economy, and governments in the United States, Europe, and beyond have taken equity in steel, energy, semiconductors, and critical minerals, often on national-security grounds. I argue that external threat drives the return of state ownership by lending it popular legitimacy, and that leaders use state-controlled resources to build state capacity and stay in power.

My research draws on a multi-method design that combines causal inference with observational data, computational text analysis, and survey experiments.

Legitimizing State Capitalism: External Threat, Nationalism, and Support for State Ownership

State ownership has outlived the socialist ideology that once justified it. In China, about half or more of citizens have favored expanding state ownership since 1990, despite decades of market-oriented reform and the well-documented inefficiency and corruption of state-owned enterprises (SOEs). I argue that, under intensifying geopolitical rivalry, the Chinese state has extended nationalism into the economy, invoking external threat to present SOEs as guardians of national security. This frame may translate into support for state ownership through two mechanisms: state firms come to stand for “us” against “them” (identity), or state control promises to insure the nation against foreign coercion (insurance). Analyses of high school textbooks and 4.3 million party newspaper articles show that the party-state has increasingly justified state ownership in nationalist terms. A factorial difference-in-differences design around the 2012 Diaoyu/Senkaku dispute shows that support for state ownership was markedly higher where exposure to nationalist mobilization was greater, a gap that opened only after the dispute. A conjoint experiment favors identity over insurance: the premium on state control is largest when SOEs are framed as safeguards against foreign threat, and no larger in chokepoint sectors such as critical minerals and high technology than elsewhere.

Economic Foundations of Authoritarian Leviathans: State-Owned Enterprises and State-Building in Contemporary China

Abstract

How has China built an extensive bureaucracy and world-leading public infrastructure despite limited tax capacity and the absence of representative institutions? I argue that under financial repression, state firms can borrow cheaply from state banks, and local governments use them both as off-budget fiscal intermediaries and as an extended arm of the state that provides public goods directly. Treating natural disasters as exogenous shocks to local fiscal pressure, I show in a firm-level difference-in-differences design that when disasters strike, local state firms borrow significantly more than private firms. A city-level panel of state-firm financial indicators shows that cities whose state sectors have greater borrowing capacity are better able to sustain their bureaucracies and public goods provision.

Sanctioned into Statism: Trade Embargoes and Public Demand for State Control

Abstract

Does the link between external threat and support for state ownership extend beyond China? Linking the Global Sanctions Database to World Values Survey respondents and using a cohort-exposure design, I find that each year of adult life under a comprehensive trade embargo significantly raises support for state ownership, an effect concentrated in non-democracies.

Modernization in the Shadow of Leviathan: State-Directed Development and the Paths to Democracy

Abstract

Does economic development bring democracy? I develop a conditional modernization theory in which state ownership of the economy diverts the gains of growth from democratization to the maintenance of authoritarian rule. Dating the onset of modern economic growth for more than 100 countries from the economic history literature, I find that rising income is accompanied by democratization mainly where the economy at take-off was in private rather than state hands.

International Origins of Populism: WTO and U.S. Presidential Elections

with Marc-Andreas Muendler, T. Renee Bowen, and J. Lawrence Broz

Abstract

To what extent do rulings on trade disputes at the World Trade Organization (WTO) affect U.S. domestic politics? We use the random assignment of WTO Appellate Body (AB) judges to disputes as an instrumental variable to predict WTO-AB rulings. We find that voters in U.S. counties more exposed to adverse WTO-AB rulings were significantly more likely to vote for the Republican candidate in the 2016 U.S. presidential elections than for the Republican candidate in 2012. We measure a county’s exposure as the cumulative share of employment in industries that are affected by AB rulings, and we control for county characteristics and other trade flows, including imports from China. We find this causal effect of WTO-AB rulings on U.S. election outcomes to depend on the average educational attainment in the county and to be concentrated in counties with a high population share of residents with less than a college degree. These findings support the view that WTO-AB rulings are salient for U.S. domestic politics and have contributed to a backlash from voters in counties whose employment was exposed to adverse WTO-AB rulings.
