One of the most important controversies in health economics concerns the question whether the imminent aging of the population in most OECD countries will place an additional burden on the tax payers who finance public health care systems. Proponents of the "red-herring hypothesis" argue that...

This paper studies a market for a medical product in which there is perfect competition among health insurers, while the good is sold by a monopolist. Individuals differ in their severity of illness and there is ex post moral hazard. We consider two regimes: one in which insurers use coinsurance...

We show that regional heterogeneity of underlying fundamentals (e.g. economic history, geography, social capital) can lead to extreme voting in federations. When the outcome of federal policies – such as transfer schemes, market regulation or migration laws – depends on these fundamentals,...

This paper reviews recent research on the aggregation of heterogeneous time preferences. Main results are illustrated in simple Ramsey models with two or three agents who differ in their discount factors. We employ an intertemporal view on these models and argue that preferences of a decision...

This paper analyzes the dynamics of trade policy reform under democracy. In an overlapping generations model, heterogeneous agents may acquire skills when young, thereby determining the skill composition of their cohort. Current and anticipated trade policies influence education decisions, and...

We introduce a new dataset that includes quantitative harmonized indices of tax reforms based on qualitative information of about 900 Economic Surveys from the OECD and 37,000 tax-related news from the IBFD archives. The data set provides indicators on tax reforms for tax rates and tax bases,...

Emigrants are less likely to participate in elections in their home country. They are also self-selected in terms of education, gender, age, and political preferences, changing the structure of the origin population. High emigration rates can therefore have a systematic influence on election...

Political connections between firms and autocratic regimes are not secret and often even publicly displayed in many developing economies. We argue that tying a firm's available rent to a regime's survival acts as a credible commitment forcing entrepreneurs to support the government and to exert...
