This paper finds a solution to some of the discrepancies between the data and what standard complete markets models predict. Specifically, those related to the cross-country correlations of consumption, output and factors of production. I match the data and get positive cross country comovements...

This paper builds a simple theoretical model designed to study dollarization. Each period, a benevolent government decides whether or not to dollarize, how much to borrow or lend on an international bond market, and, if dollarization has not occurred, the devaluation rate. In equilibrium,...

A central debate in applied macroeconomics is whether statistical tools that use minimal identifying assumptions are useful for isolating promising models within a broad class. In this paper, I extend the analysis of Chari, Kehoe, and McGrattan (2005) to compare four statistical...

At low inflation rates, the main motivation for price changes is idiosyncratic shocks to firms and industries. In standard models of sticky prices, the existence of these idiosyncratic shocks makes prices more flexible and hence monetary policy less powerful to affect real variables (and less...

This paper examines the business cycle properties of business cycle models with search frictions and wage bargaining which rely not only on labor, but also on capital in the production function. In the presence of capital, the choice of bargaining framework matters, even under perfect...

Mankiw and Reis (2002) have proposed sticky information as an alternative to Calvo sticky prices in order to model the conventional view that i) inflation reacts with delay and gradually to a monetary policy shock, ii) announced and credible disinflations are contractionary and iii) inflation...

A defining feature of business cycles is the comovement of inputs at the sectorial level with aggregate activity. Standard models cannot account for this phenomenon. This paper develops and estimates a two-sector dynamic general equilibrium model which can account for this key regularity. My...

This paper estimates the effects of technology shocks in Bayesian VAR models of the United States, Japan and West Germany, imposing restrictions on the sign of impulse responses. These restrictions are motivated with explicit priors on the parameters of a dynamic general equilibrium model...

Empirical studies document differences in firms' response to the introduction of various labor market policies. In particular, large and mature firms tend to participate more actively in targeted employment subsidy programs (under which firms receive subsidies for hiring disadvantaged workers)....
