In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a twosector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

We evaluate the effects of outsourcing and wage solidarity on wage formation and equilibrium unemployment in a heterogeneous labour market, where wages are determined by a monopoly labour union. We find that outsourcing promotes the wage dispersion between the high-skilled and low-skilled...

We study both the various consequences and the incentives of outsourcing. We argue that the wage elasticity of labour demand is increasing as a function of the share of outsourcing, which is importantly a result consistent with existing empirical research. Furthermore, we show that a production...

Several contributions have recently assessed the size of fiscal multipliers both in RBC models and New Keynesian models. None of the studies considers a model with frictional labour markets which is a crucial element, particularly at times in which much of the fiscal stimulus has been directed...

Building a model with three imperfect markets - goods, labor and credit - representing a product's life-cycle, we find that goods market frictions drastically change the qualitative and quantitative dynamics of labor market variables. The calibrated model leads to a significant reduction in the...

Unemployment may depend on equilibrium in other markets than the labor markets. This paper adresses this old idea by introducing search frictions on several markets: in a model of credit and labor market imperfections as in Wasmer and Weil (2004), I further introduce search on the goods market....

In this paper we explore the impact of imperfectly competitive input markets on production function estimation. First order profit maximizing conditions are altered when frictions in input markets cause the elasticity of input supply to the firm to be finite. A consequence of this is that the...

This paper analyzes the role of the period length in a search model of the labor market and argues that it has profound implications for the market equilibrium. In the model, job offers and job destruction shocks arrive according to a Poisson process in continuous time, but institutional factors...

We study asset-tested unemployment insurance in an incomplete markets model with moral hazard during job search. Asset testing has two counteracting effects on welfare. On the one hand, it improves consumption insurance by introducing state contingent transfers to agents most in need. On the...
