We examine the optimal financing of infrastructure when governments have limited financial commitment and can expropriate rents from private sector firms that manage infrastructure. While private firms need incentives to implement projects well, governments need incentives to limit...

The goal of this paper is to examine the shape of the Laffer curve quantitatively in a simple neoclassical growth model calibrated to the US as well as to the EU-15 economy. We show that the US and the EU-15 area are located on the left side of their labor and capital tax Laffer curves, but the...

We characterize the Laffer curves for labor taxation and capital income taxation quantitatively for the US, the EU-14 and individual European countries by comparing the balanced growth paths of a neoclassical growth model featuring "constant Frisch elasticity" (CFE) preferences. We derive...

We characterize optimal policies in a multidimensional nonlinear taxation model with bunching. We develop an empirically relevant model with cognitive and manual skills, firm heterogeneity, and labor market sorting. The analysis of optimal policy is based on two main results. We first derive an...

Stimulus checks have become an increasingly important policy tool in recent U.S. recessions. How does the households' marginal propensity to spend (MPX) vary as checks become larger? To quantify this size-dependence in the MPX, we augment a canonical model of durable spending by introducing a...

In this short paper we show that progressive income taxes distort hiring and wages when firms have labor market power. From a firm's perspective, raising pre-tax wages increases employment by less when taxes are progressive as less of the pre-tax wage is paid to workers. Understanding this when...

We give an overview of the "German model" of industrial relations. We organize our review by focusing on the two pillars of the model: sectoral collective bargaining and firm-level codetermination. Relative to the United States, Germany outsources collective bargaining to the sectoral level,...

There is much disagreement about both the facts and the explanations of income inequality. Even if we confine attention to OECD countries, we find people arguing that there has been a great U-turn, with inequality rising sharply after its post war fall, and others who believe that the speed of...
