It is widely believed that an environmental tax (price regulation) and cap-and-trade (quantity regulation) are equally efficient in controlling pollution when there is no uncertainty. We show that this is not the case if some consumers (firms, local governments) are morally concerned about...

Carbon pricing policies worldwide are increasingly coupled with direct or indirect subsidies for emission-intensive and trade-exposed firms. We analyze the incentives created by novel forms of emissions intensity-based rebating (IBR) and contrast them with more common approaches like...

We analyze a model of endogenous two-sided network formation where players are affected by uncertainty in their opponents' decisions. We model this uncertainty using the notion of equilibrium under ambiguity (Eichberger and Kelsey, 2014). Unlike the set of Nash equilibria, the set of equilibria...

Empirical evaluations of national minimum wages, such as in Germany or the UK, rely on bite measures that capture treatment variation; measured from the incidence (or intensity) of employees paid below the threshold before the minimum wage was introduced or raised. Bite-dependent estimations...

We examine a deregulation of German pharmacists to assess its effects on retail and labor markets. Our theoretical model suggests that firms with high managerial efficiency open more stores per firm and have higher labor demand due to the reform. We find a sharp persistent increase in entry...

This paper presents an overlapping generations model where agents face labor-income and health risks in order to quantify the macroeconomic and welfare consequences of reform options for the German health insurance system. In addition to labor supply, consumption and savings, households also...
