We show that in the US, the UK, Italy and Sweden women whose first child is a boy are less likely to work in a typical week and work fewer hours than women with first-born girls. The puzzle is why women in these countries react in this way to the sex of their first child, which is chosen...

In most Western countries illness-related absenteeism is higher among female workers than among male workers. Using the personnel dataset of a large Italian bank, we show that the probability of an absence due to illness increases for females, relative to males, approximately 28 days after a...

In many European countries, wages are determined by collective bargaining agreements intended to improve wages and reduce inequality. We study the local and aggregate effects of collective bargaining in Italy and Germany. The two countries have similar geographical differences in firm...

We exploit rules of class formation to identify the causal effect of increasing the number of immigrants in a classroom on natives test scores, keeping class size constant (Pure Composition Effect). We explain why this is a relevant policy parameter although it has been neglected so far. We show...

Migration may cause not only a brain drain but also a civicness drain, leading to an uncivicness trap. We study this possibility using college choices of southern-Italian students classified as Civic if not cheating in a die-roll experiment. Local civicness is the fraction of Civic in their...

Employment protection systems are known to generate significant distortions in firms' hiring and firing decisions. We know much less about the impact of these regulations on worker effort. The goal of this paper is to fill in this gap and in particular to assess whether the provision of...

We investigate empirically how sellers react to changes in the population of their consumers, identifying the effects of demand composition and demand size with limited information on costs. We show how pharmacists in Italy selectively increase the price of some products when they observe in...

We show that task juggling, i.e., the spreading of effort across too many active projects, decreases the performance of workers, raising the chances of low throughput, long duration of projects and exploding backlogs. Individual speed of job completion cannot be explained only in terms of...
