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...

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...

While it is well known that birth order affects educational attainment, less is known about its effects on earnings. Using data from eleven European countries for males born between 1935 and 1956, we show that firstborns enjoy on average a 13.7 percent premium over laterborns in their wage at...

The "Retired Husband Syndrome", that affects the mental health of wives of retired men around the world, has been anecdotally documented but never formally investigated. We use Japanese micro data and the exogenous variation generated by the 2006 revision of the Japanese Elderly Employment...

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...

Using a natural experiment designed by the Italian national test administrator (INVALSI) to monitor test procedures in Italian primary schools, this paper shows that the presence of an external examiner who monitors test procedures has both a direct and an indirect effect on the measured...

Pension reforms that raise minimum retirement age increase the pool of senior individuals aged 50+ who are not eligible to retire from the labour market. Using data from Italian provinces and regions and an instrumental variable strategy, we estimate the effects of local changes in the supply of...

By increasing the residual working horizon of employed individuals, pension reforms that raise minimum retirement age are likely to affect the returns to investments in health-promoting behaviours before retirement, with consequences for individual health. Using the exogenous variation in...
