Publications
- Firms and Wage Inequality in Central and Eastern Europe. - with Iga Magda (SGH Warsaw School of Economics) and Simone Moriconi (IÉSEG). Journal of Comparative Economics, 2021. PDF. Replication package.
Show abstract
We use large linked employer-employee data to analyze wage inequality patterns in
Central and Eastern European (CEE) countries between 2002 and 2014. We show that, unlike in many other advanced economies, wage inequality levels have decreased in almost all CEE countries. These reductions in wage inequality resulted from disproportionately large increases in wages at the bottom of the wage distribution, and from decreases in between-firm wage inequality. We further find that the declines in wage inequality were driven by large wage structure effects that compensated for changes in the composition of workers.
Working Papers
- #IamLGBT: Social Networks and Coming Out. - with Przemysław Siemaszko (SGH Warsaw School of Economics). PDF. Text analysis: keywords dictionaries.
Show abstract
In recent decades, the number of people disclosing their LGBTQ identity has increased substantially. We investigate the role of peer effects in coming out decisions using a model of a game social learning via networks. We use newly collected data from two waves of a spontaneous Twitter coming out campaign to test the prediction that observing peers coming out increases the probability of an individual disclosing their LGBTQ identity. We combine data on users' pre-campaign networks with the information on the exact time of costly coming out actions to construct a time-varying measure of the exposure to peers coming out as LGBTQ. A one standard deviation increase in the exposure increases the probability of coming out by almost 20%. We also exploit the non-overlapping network structure of users' peers groups as an exogenous source of variation, and we confirm the baseline results. We argue that the estimated effects are due to changes in beliefs about the costs of disclosure.
- Labor Supply Effects of a Universal Cash Transfer. PDF. IBS WP 02/2021.
Show abstract
I investigate the labor supply effects of the introduction of a large unconditional cash benefit. I exploit the unique design of the child benefit program in Poland to identify the income effects of the monthly transfer in a difference-in-differences design. On average, the marginal propensity to earn out of unearned income was equal to -0.14. For every extra 100 dollars in monthly child benefit transfers households receive, they spend 43 dollars on consumption and save 43 dollars. Additional evidence shows that the program had a positive impact on investments in human capital and home production efficiency.
- When Populists Deliver on Their Promises: the Electoral Effects of a Large Cash Transfer Program in Poland. - with Katarzyna Sałach (University of Warsaw) and Michał Brzeziński (University of Warsaw). PDF. IBS WP 02/2022.
Show abstract
We estimate the effects of the introduction of a large cash transfer program on support for the ruling populist party in Poland. We exploit the variation at the municipal level in the annual cash transfer amount received per capita, and use a difference-in-differences research design to study the electoral effects of the transfer. Our results show that a cash transfer amount of $100 per capita translated into an increase in the vote share for the ruling party of nearly two percentage points. We also find that these effects were largely due to the recruitment of previously non-voting individuals. We conclude that without the transfer program, all else being equal, the populist party would not have remained in power.
