Marta Lachowska's research currently focuses on three main themes:
In order to answer whether public pension systems have an effect on saving and labor supply decisions, we study Poland’s pension reform of 1999. The reform lowered future pension benefits, but had a different impact on individuals depending on their year of birth. We use this quasi-experimental variation to study the impact of the reform on household saving and labor supply before and after the reform and across individuals affected and unaffected by the reform.
We estimate the long-run effects of the Washington Alternative Work Search (WAWS) experiment. Using quarterly administrative data, we follow UI claimants’ employment and earnings over the ten years following the experiment. Previous studies of the WAWS have focused on estimating the intention-to-treat effects. We extend the analysis by examining the short- and long-term outcomes of the participants of the experiment.
