Knowledge triggers regional growth. Evidence suggests that skilled labour force concentrates in islands of innovation, determining an advantage for innovative regions and a challenge for lagging ones. We address the role of knowledge in shaping effective markets for skilled labour. Estimates are...

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. The purpose of the paper is to estimate the structure of an equilibrium model of growth through innovation that explains these facts. The model is a...

To innovate, employees need to develop novel ideas and coordinate with each other to turn these ideas into better products and services. Work outcomes provide signals about employees' abilities to the labor market, and therefore career concerns arise. These can both be 'good' (enhancing...

In a novel real-effort setting, we experimentally study the effects of different communication media on creative performance in a collaborative tasks. We find that creative performance significantly decreases when group members communicate via chat instead of face-to-face. However, we find no...

The surplus that is created in a successful entrepreneurial venture is much higher than the profit corresponding to the risk-adjusted market rate of return. The part of the surplus that exceeds this level may be denoted "entrepreneurial rent." Such rents normally disappear in the long run but...

We show that when the researcher’s (observable but not contractible) contribution to innovation is crucial, a covenant not to compete (CNC) reduces e.ort and profits under both spot and relational contracts. Having no CNC allows the researcher to leave for a rival. This alleviates a commitment...

This Paper studies the inter-temporal problem of a monopolistic firm that engages in productivity-enhancing innovations to reduce its labour costs. If the level of wages is sufficiently low, the firm's rate of productivity growth approaches the rate of wage growth and eventually the firm reaches...
