This paper studies Markov Equilibria (ME) corresponding to recursive equilibria on natural state space in the stochastic OLG model extended to include non-additive utility, nonclassical production, and Markovian production shocks. Specifically, we provide sufficient conditions under which the ME...

In this paper we investigate the quantitative importance of search and matching fric- tions in Bulgarian labor markets. This is done by augmenting an otherwise standard real business cycle model a la Long and Plosser (1983) with both a two-sided costly search and fiscal policy. This introduces a...

At the forefront of macroeconomic research on the causes of the Great Financial Cri- sis (GFC) was and still is the usage of dynamic stochastic general equilibrium (DSGE) models. To capture the nonlinearities of the GFC, these models were enriched with a variety of financial frictions. This...

We implement a new approach for the identification of news shocks about future technology. In a VAR featuring a measure of aggregate technology and several forward-looking variables, we identify the news shock as the shock orthogonal to technology innovations that best explains future variation...

In this paper, I introduce lumpy micro-level capital adjustment into a sticky information general equilibrium model. Lumpy adjustment arises because of inattentiveness in capital investment decisions instead of the more common assumption of non-convex adjustment costs. The model features...

Are uncertainty shocks a major source of business cycle fluctuations? This paper studies theeffect of a mean preserving shock to the variance of aggregate total factor productivity(macro uncertainty) and to the dispersion of entrepreneurs' idiosyncratic productivity (microuncertainty) in a...

This work introduces a new mechanism generating procyclical comovements of labor productivity, employment, through endogenous variations of workers' effort, in a simple model with efficiency wages, near a locally indeterminate steady state. A current endogenous countercyclical uncertainty shock...

In a 1957 paper, Robert Solow exploited the mathematical properties of the aggregate production function to isolate the role of disembodied “technical change” in economic growth. Solow's method allowed to disentangle the role of technical change from that of production factors, with the...

This paper uses a vector autoregression (VAR) approach to identify the driving forces of the growth slowdown in Japan during the 1990s. Negative shocks to both residential and nonresidential investment are shown to have been important determinants of the slowdown. Despite the collapse in asset...
