PhD Student in Economics

London School of Economics

Welcome!

I am currently a PhD candidate in Economics at the London School of Economics and serve as a PhD Scholar at the Institute for Fiscal Studies.

My academic journey has led me through various institutions, including IFS (researcher), Princeton (visiting PhD student, 2023), LSE (MRes in Economics, 2020), and Sharif University (MSc in Economics, 2018, and BSc in Mechanical Engineering, 2015).

My research interests are in applied microeconomics, where I utilize empirical methods to explore diverse topics. Currently, my studies are concentrated on investigating the labour market dynamics and the political economy implications of immigration.

Understanding multi-layered sanctions: A firm-level analysis

This paper examines which types of firms are hit by multi-layered sanctions, quantifies the extent of the economic impact on the affected firms, and identifies the channels through which these effects are propagated. To this end, I use a text-based approach from computational linguistics to gauge the exposure of publicly listed Iranian firms to sanctions, validating this measure through its anticipated fluctuation over time and across industries. The findings reveal three key insights. First, Iranian firms report significant challenges due to sanctions, exceeding COVID-19 concerns by up to 20%. Second, politically-connected and non-connected firms suffer equally from sanctions; for every $1 loss inflicted on connected firms, an externality of $5 is imposed on non-connected firms, considering their economic scale. This contradicts the idea that sanctions only inflict harm on political decision-makers. Third, sanctions are hurtful; firms with higher exposure to sanctions endure greater losses in stock market value in the wake of unanticipated sanction events. Sanctions also lead to reduced sales, investment and hiring. Furthermore, the study reveals that sanctions impact firms via several mechanisms, the primary one being the limitation of access to export destinations.

Immigration and Political Realignment

This paper examines how immigration reshapes political landscapes, centring on the influx of immigrants from the EU's 2004 enlargement and its implications for the UK. I use a new variation in exposure to immigration based on migrant flows across various industries coupled with the employment structure in each region. Addressing potential concerns of endogeneity, I introduce a novel shift-share IV design, harnessing the industry-specific flow of migrants to regions outside the UK within the pre-2004 EU. The findings reveal a significant impact on support for the right-wing UK Independence Party and the Brexit Leave campaign, accompanied by a decline in Labour Party support. Moreover, the research indicates that voters' social attitudes toward immigration become more adverse in response to immigration. Political parties, particularly Conservatives, are also observed to increasingly engage with the topic of immigration in constituencies most affected by immigration, typically marked by negative rhetoric. The paper reconciles these findings by highlighting how immigration shocks entrench immigration cleavage, realigning political conflict from traditional economic lines to new cultural dimensions.
