We discuss a model of a job market where firms announce salaries. Thereupon, they decide through the evaluation of a productivity test whether to hire applicants. Candidates for a job are locked in once they have applied at a given employer. Hence, such a market exhibits a specific form of the...

This paper studies the optimal mechanism for a seller (she) that sells, in a sequence of periods, an indivisible object per period to the same buyer (he). Buyer's willingness to pay remains constant along time and is his private information. The seller can commit to the current period mechanism...

In a two-firm model where each firm sells a high-quality and a low-quality version of a product, customers differ with respect to their brand preferences and their attitudes towards quality. We show that the standard result of quality-independent markups crucially depends on the assumption that...

This paper proposes a new method for welfare analysis of unfunded social security systems. Based on an overlapping generations model with endogenous labor supply, we derive a formula for the evaluation of existing pay-as-you-go social security systems that depends on impulse response functions...

We propose a new approach for performing detailed decompositions of average outcome differentials, which can be applied to all types of generalized linear models. A simulation exercise demonstrates that our method produces more convincing results than existing methods. An empirical application...

This essay examines the implications of openness to trade, capital mobility, and exchange rate flexibility for the fiscal multiplier. It presents a New Open Economy Macroeconomics model which is extended with the formation of "deep habits" by individual households. Hereby, an inter-temporal...

When decomposing differences in average economic outcome between two groups of individuals, it is common practice to base the analysis on logarithms if the dependent variable is nonnegative. This paper argues that this approach raises a number of undesired statistical and conceptual issues...

This paper analyzes the dynamic effects of a fiscal policy shock and its transmission mechanism in a small open economy and compares the responses under different specifications of the utility function. The traditional Mundell-Flemming model tells that fiscal policy is more effective under a peg...

Increasing penalty structures for repeat offenses are ubiquitous in penal codes, despite little empirical or theoretical support. Multi-period models of criminal enforcement based on the standard economic approach of Becker (1968) generally find that the optimal penalty structure is either flat...

Using a natural experiment from Germany, we show that temporary place-based subsidies generate persistent effects on economic density. We identify employment and capital formation as main channels for higher income per square kilometer. As the spatial regression discontinuity design allows us to...
