Abstract. In reviewing tentative explanations for the stagnation of productivity growth which is observed in the Italian economy, we argue that labor market policies may have played a role by worsening factor misallocation across firms. We assess this hypothesis through a battery of empirical tests using matched employer-employee data. We document a new stylized fact: following the reforms, the variance of total factor productivity has increased across industries of the Italian economy, consistently with our misallocation hypothesis.

Abstract. I provide an economic interpretation to the entropy-based probabilistic models of network formation used in statistical physics. Specifically, I show how these models are nested in a wider class of network formation models where agents are rationally inattentive about the characteristics of other agents. I develop conditions for estimating these models and provide an application about the formation of R&D alliance networks.
