We develop and analyse a real business cycle model in which both goods and labour markets are characterized by imperfect competition. In equilibrium, unemployment emerges as the result of the market power exercised by insiders at the firm level. We show that a calibrated version of the model is...

We document three changes in postwar US macroeconomic dynamics: (i) the procyclicality of labor productivity has vanished, (ii) the relative volatility of employment has risen, and (iii) the relative (and absolute) volatility of the real wage has risen. We propose an explanation for all three...

We analyze the welfare impact of greater wage flexibility while taking into account explicitly the existence of the zero lower bound (ZLB) constraint on the nominal interest rate. We show that the ZLB constraint generally amplifies the adverse effects of greater wage flexibility on welfare when...

The standard New Keynesian model with staggered wage setting is shown to imply a simple dynamic relation between wage inflation and unemployment. Under some assumptions, that relation takes a form similar to that found in empirical wage equationsstarting from Phillips(1958) original workand may...

We develop a reformulated version of the Smets-Wouters (2007) framework that embeds the theory of unemployment proposed in Gal (2011a,b). We estimate the resulting model using postwar U.S. data, while treating the unemployment rate as an additional observable variable. Our approach overcomes the...
