A Search Model of Unemployment and Inflation In this paper, I introduce money in the standard labor-matching model (Mortensen and Pissarides 1999, Pissarides 2000). A double coincidence problem makes Fiat Money necessary as a medium of exchange. In the long-run, a rise in the rate of money growth leads to higher inflation and higher unemployment, so the long-run Phillips curve is not vertical. ...

We analyze the following questions under imperfect labour markets. How does strategic outsourcing influence wage formation, profit sharing and employee effort when firms commit to optimal profit sharing before wage formation or decide for profit sharing after wage formation? What is the relationship between outsourcing, profit sharing, and equilibrium unemployment? We find that in both scenario...

This paper extends the now familiar Shapiro-Stiglitz (1984) model of labor market behavior to reconsider the controversial proposition that some forms of innovation have persistent displacement e ects. In particular, it nds that when distinctions between random production failures and reduced e ort level are di cult to draw, the adoption of new methods of production that compel more e ort, brea...

We propose a new business cycle theory. Firms need to randomize over firing or keeping workers who have performed poorly in the past, in order to give them an ex-ante incentive to exert effort. Firms have an incentive to coordinate the outcome of their randomizations, as coordination allows them to load the firing probability on states of the world in which it is costlier for workers to become ...

Search Frictions on Product and Labor Markets: Money in the Matching Function This paper builds a macroeconomic model of equilibrium unemployment in which firms persistently face difficulties in selling their production and this affects their decisions to create jobs. Due to search-frictions on the product market, equilibrium unemployment is a U-shaped function of the ratio of total demand to t...

This paper aims at explaining the dynamics of labor markets in Spain, especially the high persistence of unemployment and the Beveridge curve. We build a stochastic dynamic general equilibrium matching model, which assumes failures in the matching between vacancies and unemployed. We calibrate the model for the Spanish economy and simulate it considering two sources of exogenous shocks: a techn...

We analyze how the financial conditions of the firm affect the compensation structure of workers, the size of the firm, and its dynamics. Firms that are financially constrained offer long-term wage contracts characterized by an increasing wage profile, that is, they pay lower wages today in exchange of higher future wages, effectively borrowing from their employees. Because constrained firms al...

The reservation wage is an integral part of most theories of involuntary unemployment. We use panel data to examine the empirical determinants of the reservation wage — in particular the inßuence of previous wages — and consider what this implies for the evolution of the natural rate of unemployment. We Þnd that previous wages have a signiÞcant but relatively small effect on reservation wages (...

We consider a dynamic macroeconomic model with households that regard relative affluence as social status. The measure of relative affluence can be the ratio to, or the difference from, the social average. The two specifications lead to quite different results: with the ratio specification full employment is necessarily realized, whereas with the difference specification persistent shortages of...

This paper is motivated by the lack of any obvious relationship between aggregate poverty and unemployment in Great Britain. We derive a framework based on individuals’ risks of unemployment and poverty, and how these vary over the economic cycle. Analysing the British Household Panel Survey for 1991-96, we are able to square the micro evidence that unemployment matters for poverty with the mac...
