A substantial fraction of a worker's time at work goes to acquiring human capital. This paper explicitly considers on-the-job human capital accumulation from the perspective of time invested for acquiring skills and learning by doing in an RBC model and shows that the inability to account for...

Using ideas from the endogenous growth literature, we present a model of the endogenous determination of productivity growth based on individual worker decisions about human capital investment. We calibrate a version of the model to match long run growth facts from the US and study the business...

Do fluctuations of the labor wedge, defined as the gap between the firm's marginal product of labor (MPN) and the household's marginal rate of substitution (MRS), reflect fluctuations of the gap between the MPN and the real wage or fluctuations of the gap between the real wage and the MRS? For...

This paper presents a DGE model in which aggregate price level inertia is generated endogenously by the optimizing behaviour of price-setting firms. All the usual sources of inertia are absent here ie., all firms are simultaneously free to change their price once every period and face no...

Shimer (2005a) argues that the textbook equilibrium search model of unemployment explains less than 10% of the volatility in U.S. vacancies and unemployment when fluctuations are driven by productivity shocks. His paper as well as other recent work inspired by it are reviewed and extended here....

Structural Vector Autoregressions with a differenced specification of hours (DSVAR) suggest that productivity shocks identified using long--run restrictions lead to a persistent and significant decline in hours worked. This evidence calls into question standard business cycle models in which a...

The standard Real Business Cycle literature mainly focuses on Walrasian models designed to fit the US institutional framework. Differences between the US and Europe, mostly evident in the labor market, suggest that a purely Walrasian model may be inappropriate to study European business cycles....

We build a New Keynesian model of the business cycle with sticky prices and real wage rigidities motivated by efficiency wages of the gift exchange variety. Compared to a standard sticky price model, our Fair Wage model provides an explanation for structural unemployment and generates more...

Most of the papers in the sticky-price literature are based on a log-linearization around the zero inflation steady state, a simplifying but counterfactual assumption. This paper shows that when trend inflation is considered, both the long-run and the short-run properties of DGE models based on...

Chari, Kehoe, and McGratten's (1998) finding that a standard monetary business cycle model with staggered price setting is unable to generate sufficiently persistent real effects of monetary shocks has engendered a growing literature aimed at developing alternative mechanisms for producing...
