This paper estimates ability peer effects on achievement growth in reading and math. It exploits variation in peer characteristics generated at the transition from primary to secondary school in a sample of Berlin fifth-graders. As will be discussed in detail, this variation is exogenous in...

Between 1960 and 1979, 93 new universities opened in Germany. Using this large tertiary education expansion, I estimate the effect of a university opening on the probability of obtaining a university degree in the local population. I exploit the geographical variation in local university access...

We investigate the responsiveness of individual retirement decisions to changes in financial incentives. The causal effect is identified based on the natural experiment generated by an institutional reform. The results of a binary retirement model are robust to alternative model specifications,...

We use reforms in the Swiss public retirement system to identify the responsiveness of retirement timing to financial incentives. A permanent reduction of retirement benefits by 3.4 percent induces more than 70 percent of females to postpone their retirement. The responsiveness of male workers,...

This paper examines the effect of the introduction of permanent benefit reductions for early retirees (i) on the duration until retirement entry and (ii) on the duration until exit from gainful employment. I estimate discrete time duration models using different error term specifications....

Measuring the effect of ballot access restrictions on electoral competition is compli- cated because the stringency of ballot access regulations cannot be treated as being exogenous to candidates' entry decisions. This paper exploits the 1968 U.S. Supreme Court decision to strike down Ohio's...

This paper estimates the impact of peer achievement and variance on math achievement growth. It exploits exogenous variation in peer characteristics generated at the transition to upper-secondary school in a sample of Berlin fifth graders. Parents and schools are barely able to condition their...
