Although new Keynesian models with labor market frictions report an increase in unemployment and a decrease tightness response to positive technology shock, which appears be line recent empirical findings, the volatilities of these variables are not as high their counterparts. This calls for introduction modeling tools amplify rate tightness. Along this line, paper contributes theoretical liter...

Can the historical equity premium be explained as a rational equilibrium outcome when riskaverse agents with conventional preferences are faced with non-diversifiable sources of risk (e.g., from labor or entrepreneurial income), and when trading frictions prevent them from using financial assets to effectively self-insure transitory shocks? Our research suggests that it is difficult to generate...

We characterize optimal redistributive taxation when individuals are heterogeneous in their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are endogenous. Average tax rates are increasing at the optimum. This shifts wages below their laissez faire value and distorts labor demand upwards....

The majority of OECD countries has experienced a reduction in macroeconomic volatility during the last two decades. This period is also characterized by a gradual liberalization of the capital accounts of from these countries. The goal of this paper is to study whether capital markets liberalization can lead to lower macroeconomic volatility. We study a business cycle model with multiple countr...

This paper examines the effect of financial frictions on the strength of the monetary transmission mechanism. Credit channel theory implies that the transmission mechanism of monetary policy should be stronger in countries with high levels of financial frictions, all else equal. The intuition is that in these countries, external finance premiums are more sensitive to firms’ financial leverage. ...

Optimal Price Indices for Targeting Inflation under Incomplete Markets In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a twosector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with financial frictions. Financial frict...

Multiple Equilibria and Minimum Wages in Labor Markets with Informational Frictions and Heterogeneous Production Technologies It is often argued that a mandatory minimum wage is binding only if the wage density displays a spike at it. In this paper we analyze a model with search frictions and heterogeneous production technologies, in which imposition of a minimum wage affects wages even though,...
