In this paper we investigate the nexus between firm labor diversity and innovation using a linked employer-employee data from Denmark. Specifically, exploiting information retrieved from this comprehensive database and implementing proper instrumental variable strategies, we are able to identify...

The firm's stock of human capital is an important determinant of its ability to innovate. As such, any increase in this stock through firm-sponsored training might lead to more innovation. We test this hypothesis using detailed data on firms' human capital investments and innovation performance,...

This paper studies the design of optimal contracts in dynamic environments where agents learn by doing. We derive a condition under which contracts are fully incentive compatible. A closed-form solution is obtained when agents have CARA utility. It shows that human capital accumulation...

A pre-condition for employer learning is that signals at labor market entry do not fully reveal graduates' productivity. I model various distinct sources of signal imperfection - such as noise and multi-dimensional types - and characterize their implications for the private return to skill...

Artificial Intelligence (AI) is a potentially powerful tool in the fight against the COVID- 19 pandemic. Since the outbreak of the pandemic, there has been a scramble to use AI. This article provides an early, and necessarily selective review, discussing the contribution of AI to the fight...

Employee referrals are a very common means by which firms hire new workers. Past work suggests that workers hired via referrals often perform better than non-referred workers, but we have little understanding as to why. In this paper, we demonstrate that this is primarily because referrals allow...

How should the productivity of research universities be measured? This task is difficult but important. The recent Research Excellence Framework in the UK, which was based on peer review, suggests that there has been a marked improvement in UK academic research in economics and in many other...

We use Canadian linked employer-employee data to examine gender differences in probability, duration, and intensity of firm-sponsored training. We find that women in the for-profit sector are less likely to receive classroom training, and receive shorter classroom training courses. However, we...
