When school quality increases with the educational standard set by schools, education before college need not be a hierarchy with private schools offering better quality than public schools. In our model, private schools can offer a lower educational standard at a positive price because they...

We use data on international chess tournaments to study the relationship between age and mental productivity in a brain-intensive profession. We show that less talented players tend to leave the game in the earliest phases of their career. When the effects of age on productivity vary with...

We use data on professional chess tournaments to study how endogenous selection affects the relationship between age and mental productivity in a brain-intensive profession. We show that less talented players are more likely to drop out, and that the age-productivity gradient is heterogeneous by...

We use a natural experiment to show that the presence of an external examiner in standardized school tests reduces the proportion of correct answers in monitored classes by 5.5 to 8.5% – depending on the grade and the test – with respect to classes in schools with no external monitor. We...

We use a natural experiment to show that the presence of an external examiner has both a direct and an indirect negative effect on the performance of monitored classes in standardized educational tests. The direct effect is the difference in the test performance between classes of the same...

In spite of their relative vicinity Scandinavian countries and Central European countries (mainly Germany) have substantially different schooling institutions. While the former group of countries delays school tracking until age 16, the latter group anticipates differentiation between age 10 and...

During the postwar period, many countries have de-tracked their secondary schools, based on the view that early tracking was unfair. What are the efficiency costs, if any, of de-tracking schools? To answer this question, we develop a two skills - two jobs model with a frictional labour market,...

Secondary schools in the developed world differ in the degree of differentiation and in the first age of selection of pupils into different tracks. In this paper, we account for the heterogeneity of tracking time with a simple stochastic model which conjugates the returns from specialization...

Motivated by anecdotal as well as econometric evidence from Italy, we ask whether private schools can provide lower quality than public schools. Using a stylized model of the education market with sequential entry of a public and a private school, we show that, depending on the underlying...
