We study the updating of beliefs under ambiguity for invariant biseparable preferences. In particular, we show that a natural form of dynamic consistency characterizes the Bayesian updating of these beliefs.

This paper studies the costs and benefits of delegating decisions to superiorly informed agents relative to the use of rigid, non discretionary contracts. Delegation grants some flexibility in the choice of the action by the agent, but also requires the use of an appropriate incentive contract...

This paper considers local and global multiple-prior representations of ambiguity for preferences that are (i) monotonic, (ii) Bernoullian, i.e. admit an affine utility representation when restricted to constant acts, and (iii) locally Lipschitz continuous. We do not require either Certainty...

This paper analyzes preferences in the presence of ambiguity that are rational in the sense of satisfying the classical ordering condition as well as monotonicity. Under technical conditions that are natural in an Anscombe-Aumann environment, we show that even for such general preference model...

This paper provides a multiple-priors representation of ambiguous beliefs à la Ghirardato, Maccheroni, and Marinacci (2004) and Nehring (2002) for any preference that is (i) monotonic, (ii) Bernoullian, i.e. admits an affine utility representation when restricted to constant acts, and (iii)...

Using a panel of administrative Italian data (source: INPS), this paper provides new empirical evidence on the earnings mobility in Italy over a relatively long time period (1985-1996). Transition matrices have been used to document the extent to which Italian employees change their position in...

A higher job creation is a common result by many theoretical approaches trying to model marginal labor market reforms. In the framework proposed by Berton and Garibaldi [2006], in particular, the equilibrium arrival rate of temporary job offers is expected to be higher than the arrival rate of...

The liberalization of fixed term contracts in Europe has led to a two tier regime, with a growing share of jobs covered by temporary contracts. The paper proposes a matching model with direct search in which temporary and permanent jobs coexist in a long run equilibrium. When temporary contracts...

We use a unique data set providing administrative information on earnings by skill-level (blue collars, white collars), on the local stock of human capital and on several firm’s characteristics, including balance sheet data, to investigate the size of localized human capital externalities in...

This paper studies gender wage differentials in Italy by providing a structural estimation of the frictional parameters of two different theoretical specifications of an equilibrium search model. I alternatively allow for firm heterogeneity and discrimination empirically using maximum likelihood...
