We study the effect of Amazon products competing with 3rd-party products on marketplace by using a staggered diff-in-diff design for Amazon entry. We find that Amazon entry is associated with modest positive effects on both consumer and third-party merchant outcomes, which are more consistent with mild market expansion than with appropriating third-party sales.

I explore job mobility and earnings growth using detailed administrative data of Asutrian social security records. I uncover that earnings growth slows around age 30, after which job changes are increasingly less about higher pay. Using voluntary job transitions, I establish a preference ranking over firms and use it to estimate the role of systematic non-pay benefits, or ‘amenities’, in career moves. This study offers a fresh perspective on labor economics, emphasizing the importance of non-monetary factors in our career decisions.

Short-time work - a job retention subsidy conditional on hour reductions - has become an important policy tool despite a lack of agreement on which market failures it addresses. To fill the gap, we use Optimal-control theory to develop a model of job retention policies in the presence of asymmetric information. When individual productivity shocks are not observable, short-time work helps to target subsidies towards jobs at risk.
