Abstract:
The 1965–66 anti-communist purge in Indonesia eliminated hundreds of thousands of suspected Communist Party (PKI) affiliates and inaugurated a durable regime of political exclusion. This paper examines how post-purge repression reshaped demographic transition in Java. Exploiting municipal variation in PKI victories in the 1955 election and cohort-level data constructed from the 2010 population census, the analysis implements a two-way fixed-effects event-study design. Municipalities where the PKI previously won experience a large and delayed decline in births. The effect operates primarily through reduced marriage formation rather than fertility within marriage. Contrary to conventional displacement accounts, cohorts born after 1964 are less likely to migrate, indicating constrained mobility. Additional evidence shows that administrative screening limited access to formal employment, especially for men from PKI strongholds. The findings demonstrate how institutionalized repression can generate persistent demographic change through labor-market and household formation channels.

Abstract:
This paper examines the long-run labor market effects of childhood exposure to Indonesia's most severe episode of religious violence, the Christian-Muslim conflict in Sulawesi. Linking the pooled 2023 and 2024 Indonesian Labor Force Survey with the Socioeconomic Survey, we employ a difference-in-differences design based on birth municipality and cohort timing around the conflict's stabilization in 2004. We find that childhood exposure reduces adult earnings by 22.44%. Exposed individuals are 12.72 percentage points more likely to work in the informal sector, and a distributional analysis reveals a reallocation of workers from the formal-sector wage range into the informal-sector wage range. Two mechanisms drive the results. The conflict reduces educational attainment, lowers the probability of completing junior and senior high school, and decreases standardized test scores, while also producing lasting health deterioration. Migration increases among exposed individuals but does not offset the earnings penalty. Overall, the results highlight the lasting economic costs of childhood exposure to communal violence operating through both health and education channels.

Education, Religious Segregation, and Interfaith Marriage
Presented at: Alp-Pop, La Thuile; EEA Congress, Bordeaux.
Abstract:
Interfaith marriage represents the highest level of social cohesion between religious groups, fostering cooperation and integration between majority and minority communities. However, in traditional societies, such unions are often discouraged or even prohibited by families with conservative religious beliefs. This research examines the role of education in breaking the barrier of interfaith marriage using the case of Indonesia—a predominantly Muslim nation with a history of religious conflicts. Leveraging data from a large-scale school construction program, my study investigates the causal impact of an education expansion program on interfaith marriage. My exercises reveal that the program significantly increased the likelihood of interfaith marriages, primarily by reducing objections to such unions within Muslim communities. This shift in perceptions is largely driven by an increase in interfaith trust rather than changes in individual religiosity and interfaith tolerance. The analysis suggests that expanding educational opportunities can promote social cohesion, even in societies prone to interfaith conflict.
