We analyze costly information acquisition and information revelation in groups in a dynamic setting. Even when group members have perfectly aligned interests the group may inefficiently delay decisions. When deadlines are far away, uninformed group members freeride on each others' efforts to...

Incentives to invest in higher education are affected by both the direct wage effect of human capital investments and the indirect wage effect resulting from lower unemployment risks and shorter spells in unemployment associated with higher educated. We analyse the returns to education in...

Political economy factors tend to induce many governments to spend on private goods (non-social subsidies) to the detriment of spending on social and public goods. We show that this bias in spending patterns is particularly costly for economic growth when capital markets are imperfect. We thus...

The compensated taxable income elasticity at a given income level is proportional to the number of individuals who bunch at a convex kink point. This holds true even in the presence of optimization frictions if the jump in marginal tax rates is suciently large. In this paper we estimate bunching...

The Mirrlees Review recommends that commodity taxation should in general be uniform, but with some goods consumed in conjunction with labour supply (such as child care) left untaxed. This paper examines the validity of this claim in an optimal income tax framework. Contrary to the recommendation...

One of the main features of health insurance is moral hazard, as defined by Pauly (1968); people face incentives for excess utilization of medical care since they do not pay the full marginal cost for provision. To mitigate the moral hazard problem, a coinsurance can be included in the insurance...

The incidence and efficiency losses of taxes have usually been analyzed in isolation from public expenditures. This negligence of the expenditure side may imply a serious misperception of the effects of marginal tax rates. The reason is that part of the marginal tax may in fact be a payment for...

Political survey data for nine West European countries show that women have become increasingly left-wing compared to men, and that this trend is positively correlated with the decline in marriage in these countries. This pattern is mirrored in German longitudinal data (GSOEP), where transitions...

The governments of nearly all countries are major providers of primary and secondary education to their citizens. In some countries, however, public schools coexist with private schools, while in others the government is the sole provider of education. In this study, we ask why different...
