This paper analyzes the influence of the shadow economy on corruption and vice versa. We hypothesize that corruption and shadow economy are substitutes in high income countries while they are complements in low income countries. The hypotheses are tested for a crosssection of 120 countries and a...

We investigate the responsiveness of individual retirement decisions to changes in financial incentives. A reform increased women's normal retirement age (NRA) in two steps from age 62 to age 63 first and then to age 64. At the same time retirement at the previous NRA became possible at a...

We use an excludable instrument to test the effect of foreign aid on economic growth in a sample of 96 recipient countries over the 1974-2009 period. We interact donor government fractionalization with a recipient country's probability of receiving aid. The results show that fractionalization...

We investigate the effects of short-term political motivations on the effectiveness of foreign aid. Donor countries ́political motives might reduce the effectiveness of conditionality, channel aid to inferior projects or affect the way aid is spent in other ways, reduce the aid bureaucracyś...

We study the labor supply effects of a change in child-subsidy policy designed to both increase fertility and shorten birth-related employment interruptions. The reform yields most of the intended effects. -- Female labor supply ; fertility ; child subsidy ; parents money

We investigate the unemployment pathway to retirement in Germany and study the causal effects of two early retirement reforms. Reform 1 (NRA) increased normal retirement age stepwise from 60 to 65. Simultaneously, it became possible to use early retirement with benefit discounts. Reform 2 (ERA)...

Performance-based aid has been proposed as an alternative to the failed traditional approach whereby donors make aid conditional on the reform promises of recipient countries. However, hardly any empirical evidence exists on whether ex post rewards are effective in inducing reforms. We attempt...

We exploit the 1996 reform of the German child benefit program to identify the causal effect of heterogeneous child benefits on fertility. While generally the reform increased child benefits, the exact amount of the increase varied by household income and the number of children. We use these...
