This paper explores the effect of various contract-awarding procedures in public procurement on the price of the contract. We provide a theoretical model that compares prices in different procedures and tests whether there is a significant price difference between the procedures using data from...

This paper examines the causal effects of air pollution on migration by exploiting a natural experiment in which desulfurization technologies were rapidly implemented in coal-burning power plants in the Czech Republic in the 1990s. These technologies substantially decreased air pollution levels...

We exploit a quasi-natural experiment that emerged during the Czech presidential run-off election to identify the impact of inaccurate and misleading information on electoral outcomes. A political campaign associated a vote for one of the candidates with a legally and politically unfounded risk...

This paper examines causal effects of air pollution on migration by exploiting a unique natural experiment of desulfurization of power plants in the region of North Bohemia in the Czech Republic after the fall of communism in 1989. The results based on a difference-in-difference estimator show...

This paper tests for discriminatory treatment of the Roma minority by public officials in the Czech Republic. Our focus is on public servants at local job centers whose job is to advise unemployed individuals and process applications for unemployment benefit. Our experimental design facilitates...
