Thomas Mikaelsen
Phd Student in Economics
I am a 4th year Ph.D. student in Economics at Stockholm University.
My research examines the impact of environmental pollutants, like agricultural pesticides, on health, labor market outcomes, and biodiversity, and explores policy solutions. Additionally, I work on questions in public economics and labor economics relating to artificial intelligence, unionization, and taxation.
My advisors are David Seim and Torsten Persson.
I am visiting Raj Chetty at Opportunity Insights in spring 2025.
I am affiliated with Statistics Denmark, the Machine Learning & Global Health Network, and the Department of Economics at the University of Copenhagen.
I hold a B.Sc. in Mathematics from Aarhus University and an M.Sc. in Econometrics and Mathematical Economics from the London School of Economics.

The Causal Effect of Collective Bargaining Agreements
This project investigates the causal effect of collective bargaining agreements (CBAs) at the firm level on worker and firm outcomes in Denmark. To estimate this effect, I use a regression discontinuity design that leverages the rule enabling office workers to force firms to sign a CBA with the union HK Privat if at least 50% of their office workers are union members. The analysis combines novel data on all HK Privat union members and firms with matched employer-employee records and firms' balance sheet data to study outcomes for workers and firms.
Cost of Failure: Entrepreneurship, Risk and Insurance
I show that entrepreneurs in the four Nordic countries respond significantly to changes in the Minimum Capital Requirement (MCR) when starting a Limited Liability Corporation (LLC). This behavior is driven primarily by two types of entrepreneurs: 'switchers' and 'diversifiers'. Switchers transition their business from a sole proprietorship to an LLC, while diversifiers create holding companies for their existing subsidiaries. Both types are motivated by risk management, as LLCs shield entrepreneurs from personal liability in the event of bankruptcy. The MCR effectively serves as the price of entrepreneurial bankruptcy insurance. Lowering the MCR enables marginal firms to take on more debt and grow faster, while allowing entrepreneurs with less liquidity to incorporate, thus promoting entrepreneurship among those from lower socioeconomic backgrounds.
