How does renegotiation affect contracts between a principal and an agent subject to persistent private information and moral hazard? This paper introduces a concept of renegotiationproofness, which adapts to stochastic games the concepts of weak renegotiation-proofness and internal consistency...

We study reforms of non-linear income tax systems from a political economy perspective. We present a median voter theorem for monotonic tax reforms, reforms so that the change in the tax burden is a monotonic function of income. We also provide an empirical analysis of tax reforms, with a focus...

Promise competition is prevalent in many economic environments, but promise keeping is often difficult to observe. We study the value of transparency for promise competition and ask whether promises still offer an opportunity to honor future obligations when outcomes do not allow for observing...

The ifo Education Survey is a representative opinion survey of the German voting-age population on education topics that has been conducted annually since 2014. It covers public preferences on a wide range of education policy issues ranging from early childhood education, schools, and...

Are reforms towards individual taxation politically feasible? Are they desirable from a welfare perspective? We develop a method to answer such questions and apply it to the US federal income tax since the 1960s. Main findings are: As of today, Pareto-improvements require a move away from joint...

Public preferences for charging tuition are important for determining higher education finance. To test whether public support for tuition depends on information and design, we devise several survey experiments in representative samples of the German electorate (N19,500). The electorate is...

Wir analysieren das Gesetz zur Angemessenheit der Vorstandsvergütung. Ferner arbeiten wir einige aufgrund wirtschaftswissenschaftlicher Überlegungen zu erwartende Probleme heraus und prognostizieren mögliche ökonomische Auswirkungen des Gesetzes. Des Weiteren gehen wir im Rahmen einer...

In Spence's (1973) signaling by education model and in many of its extensions, firms can only infer workers' productivities from their education choices. In reality, firms also use sophisticated pre-employment auditing to learn workers' productivities. We characterize the trade-offs between...

Existing theories of a firm\'s optimal capital structure seem to fail in explaining why many healthy and profitable firms rely heavily on equity financing, even though benefits associated with debt (like tax shields) appear to be high and the bankruptcy risk low. This holds in particular for...

The corporate finance literature documents that managers tend to over-invest in their companies. A number of theoretical contributions have aimed at explaining this stylized fact, most of them focusing on a fundamental agency problem between shareholders and managers. The present paper shows...
