When analyzing panel data using regression models, it is often reasonable to allow for time-varying covariate effects. We propose a novel approach to modelling timevarying coefficients in panel data regressions, which is based on penalized regression techniques. To illustrate the usefulness of...

We study risk taking on behalf of others in an experiment on a large random sample. The decision makers in our experiment are facing high-powered incentives to increase the risk on behalf of others through hedged compensation contracts or with tournament incentives. Compared to a baseline...

This paper introduces an experimental economy with boundedly rational agents that compete with local, and largely incommunicable industrial knowledge, in an international market environment with more or less unbounded, commercial opportunities. Predictability of outcomes at the micro level is...

It is extraordinarily difficult to determine the extent to which the gender wage gap reflects discriminatory behaviors by employers or differences in productive capacities between men and women. We note that where piece-rate work is performed, wages should in principle reflect productivity...

We show that officer training during the Swedish military service has a strong positive effect on the probability to attain a managerial position later in life. The most intense type of officer training increases the probability of becoming a civilian manager by about 5 percentage points, or 75...
