This paper estimates the impact of college teaching on students’ academic achievement and labor market outcomes using administrative data from Bocconi University (Italy) matched with Italian tax records. The estimation exploits the random allocation of students to teachers in a fixed sequence of compulsory courses. We find that good teaching matters more for the labor market than for academic performance. Moreover, the professors who are best at improving the academic achievement of their best students are also the ones who boost their earnings the most. On the contrary, for low ability students the academic and labor market returns of teachers are largely uncorrelated. We also find that professors who are good at teaching high ability students are often not the best teachers for the least able ones. These findings can be rationalized in a model where teaching is a multi-dimensional activity with each dimension having differential returns on the students’ academic outcomes and labor market success.
We analyze segregation between immigrants and natives at the firm level and explore the connection between segregation and wage inequality in Switzerland.
In his presidential address, Zingales (2015) observes that large parts of society perceive finance as a rent-seeking activity and that complex financial regulation is prone to arbitrage and capture. In my dissertation, I investigate whether there is some truth in these allegations. In Chapter 1, I estimate the extent of regulatory arbitrage by banks in the securitization market. In Chapters 2 and 3, I show how incentive structures in credit rating agencies and banks can explain credit rating bias and excessive risk-taking, respectively. My findings have important implications for the design of financial regulation.
This thesis explores the impact that two types of non-conventional barriers - non-tariff measures (NTMs) and cultural traits - have on trade. The first essay deals with the asymmetric impact that NTMs can have on trading partners and provides estimates of the bilateral effects of NTMs (in terms of ad valorem equivalents) across exporter-importer pairs. The second essay finds support that, at the global level, the negative impact of NTMs on trade is greater with respect to final goods (“NTM escalation”), but that there is a degree of NTM de-escalation as one moves from primary goods to intermediate goods. The third essay investigates what role, if any, that the cultural traits of trust propensity and agreeableness might have on international trade and shows that their impact is limited when considered in isolation, but that trust propensity has a strong and positive effect on trade when it is interacted with distance.
