This paper studies public goods provision in an experiment in which contributors repeatedly interact with rent-extracting administrators. Our main result is that the presence of an administrator reduces contributions but only because rent extraction lowers the MPCR. Analysing the dynamic...

We present controlled experimental evidence on how rent extraction by an administrator affects giving to non-profit associations. Holding the price of giving constant, we compare contributions between two conditions: a rent extraction condition, in which an administrator can expropriate a part...

Ineffective fundraising lowers the resources charities can use for goods provision. We combine a field experiment and a causal machine-learning approach to increase a charity's fundraising effectiveness. The approach optimally targets fundraising to individuals whose expected donations exceed...

We address the role of labor cost differentials for national tax policies. Using a simple theoretical framework with two countries competing for a mobile firm, we show that in a bidding race for FDI, it is optimal for governments to compensate firms for international labor cost differentials....

Recent contributions to the political economics literature (Trebbi et al. 2007; Aghion et al. 2004) have challenged the view that political institutions are exogenous to the behaviour of agents in the political arena. We explicitly address the potential endogeneity of institutions by examining the...

We set up a model to characterize the reaction functions of governments competing for mobile capital by simultaneously setting both the business tax rate as well as the level of provision of a productive public input. Using a rich data set of local jurisdictions, we then test the predictions of...

We reassess the driving forces behind the recent decline of corporate tax rates in Europe. Using data for up to 32 countries from 1983 to 2006, we analyze the role of economic and financial openness as well as tax competition while allowing for dynamic adjustment to shocks and period-specific as...

The deterrent effect of law enforcement rests on the link between the actual and the perceived detection risk. We study the role of word of mouth for this linkage. Our approach makes use of micro data on compliance with TV license fees allowing us to distinguish between households who have been...

This paper studies how imposing norms on contribution behavior affects individuals' intrinsic motivation. We consider the church levy, which the Catholic Church in Germany collects as a charitable donation, despite the fact that the levy is legally a tax. We design a randomized field experiment...

The paper argues that economic integration causes problems for the labor market of high-wage countries due to cross-border labor mobility and the accompanying increase in labor supply. Empirical evidence is provided from an analysis of regional labor market effects of German re-unification. In...
