We use a standard quantitative business cycle model with nominal price and wage rigidities to estimate two measures of economic inefficiency in recent U.S. data: the output gap---the gap between the actual and efficient levels of output---and the labor wedge---the wedge between households'...

Is there a relation between wage bargaining institutions and unemployment? The humpshape hypothesis�, first introduced by Calmfors and Driffill (1988), states that countries with highly centralized and highly decentralized wage bargaining processes have a superior performance in terms of...

This paper shows that convexity of the short-run Phillips curve is a source of positive inflation bias even when policymakers target the natural unemployment rate, that is when they operate with prudent discretion, and their loss function is symmetric. Optimal monetary policy also induces...

At the end of the last decade, the real activity in Colombia underwent the sharpest recession of the last fifty years. We postulate a non-triangular structural VAR model(Amisano and Giannini, 1997) to describe the dynamics of output, prices, unemployment and wages during the last two decades....

Este documento reporta los resultados de la estimación econométrica de un modelo de la tasa de participación para cuatro categorías de miembros del hogar (13 ciudades): mujeres comprometidas (casadas o en unión permanente), mujeres no comprometidas (solteras, viudas o separadas), hombres...

Se estima el componente de largo plazo de la tasa de desempleo en Colombia para los últimos veinte años. De acuerdo con los resultados, los principales determinantes del componente permanente de la tasa de desempleo son el salario real por hora, los costos laborales no salariales y la tasa de...

The colombian urban unemployment rate grew dramatically over the last six years. At the same time the real wage also had a sharp increase: The empirical evidence supports the hypothesis that an exogenous increase in the real wage was a cause of the unemployment growth. The long-run elasticity...

Este documento describe la evolución de la tasa de desempleo urbano en Colombia en el período 1984:1-2000:2. Incluye evidencia sobre algunas de las propiedades de las series de tiempo del mercado laboral tales como las tasas de desempleo, de ocupación y de participación. Se estiman las...

The dynamic general equilibrium model with hiring costs presented in this paper delivers involuntary unemployment in the steady state as well as involuntary fluctuations in unemployment. The existence of hiring friction introduces externalities that, in turn, entail the breakdown of the "divine...

In this paper we analyze a general equilibrium dynamic stochastic New Keynesian model characterized by labor indivisibilities, unemployment and a unionized labor market. The presence of monopoly unions introduces real wage rigidities in the model. We show that as in Blanchard Galì (2005) the so...
