Since 1998, public firms have had to adapt to a market environment that is verydifferent from the post-war era in Europe. The liberalisation of services of generaleconomic interest across Europe led to competition between public and privateproviders, while new technologies require infrastructure investment and innovativesolutions.

Design flaws in the Eurozone institutional architecture have contributed importantly to this lack of convergence. This is why further reforms are urgently needed. ...

We discuss the short‐run effects of this new minimum wage on a wide set of socioeconomic outcomes, such as employment and working hours, earnings and wage inequality, dependent and self‐employment, as well as reservation wages and satisfaction. We also discuss difficulties ...
We analyze whether mothers’ parental leave decisions depend on their coworkers’ decisions.

We therefore exploit quasi-random variation in the costs of parental leave induced by a policy reform in Germany. The reform encourages mothers to remain at home during the first year following ...
An interaction in a fixed effects (FE) regression is usually specified by demeaning the product term. However, this strategy does not yield a genuine within estimator. Instead, an estimator is produced that reflects unit-level differences of interacted variables whose moderators vary within units. This is desirable if the interaction of one unit-specific and one time-dependent variable is specified ...
