We apply a three-tier hierarchical model of regulation, developed along the lines of Laffont and Tirole’s (1993), to an adverse selection problem in the corporate bond market. The bank brings the bonds to the market and informs the potential buyers about the bonds’ risk; a unique...

In this paper we analyze a model of price competition in a market for a homogeneous product in which consumers express a probabilistic demand. A parameter, θ, describes the degree of precision with which consumers evaluate prices. We show that, according to the value of θ, the market can...

This paper analyzes the wage returns from internal migration for recent graduates in Italy. We employ a switching regression model that accounts for the endogeneity of the individual’s choice to relocate to get a job after graduation: the omission of this selection decision can lead to...

The model developed in this paper highlights the structure of costs and benefits on which the decisions of investment in human capital by firms and workers depend under the hypothesis of imperfect labour markets. In this case, the wage after the training period remains below productivity....

The labor market is receiving increasing attention in the New Keynesian literature. In this paper I critically survey this literature in order to highlight the role played by wage rigidities in the explanation of fluctuations caused by technology shocks. To this aim, I present a DSGE model with...

This paper develops a simple New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model with rule-of-thumb consumers and external habits. Our theoretical model has a closed-form solution which allows the analytical derivation of its dynamical and stability properties. These properties are...

The aim of this paper is to verify if a proper SVEC representation of a standard Real Business Cycle model exists even when the capital stock series is omitted. The argument is relevant as the common unavailability of su¢ ciently long medium-frequency capital series prevent researchers from...

In this paper we propose straightforward extensions of multi-union, monopolistic competition models appearing in the recent literature on the macroeconomic effects of monetary policy. We extend these models from the Stackelberg equilibrium to the Nash equilibrium under variations in labor market...

This paper proposes a stylized two-period two-country model illustrating the role played by the distribution of domestic wealth in determining a country’s level of access to international lending. We model sovereign debt redemption policy as the outcome of the interaction between the...

The aim of this paper is to bring together two recent developments in the â€contracting†approach to the time-inconsistency problem of monetary policy: linear contracts under common agency and central bank preference uncertainty under single agency. We show that under common agency and...
