In this paper we feature the optimal unemployment benefits financing scheme when the economy is subject to labor market failures. We are particulary interested in the effects of search frictions and wages rigidity. The goal of this paper is to show how policy instruments should interact with...

We develop a stochastic model of random search on the job, with ex-ante heterogeneous workers and firms and aggregate productivity shocks in which firms make state contingent offers and counter offers to workers. The model delivers rich dynamics in which the distributions of unemployed workers,...

We develop a model in which policy makers' reputation for Fiscal Virtue evolves over time. Fiscal Virtue is generally desirable because it leads to a stable macroeconomic environment, but when entering the zero lower bound, policy makers face a trade-off between preserving their reputation and...

This paper investigates the effectiveness of central bank communication when firms have heterogeneous inflation expectations that are updated through social dynamics. The bank's credibility evolves with these dynamics and determines how well its announcements anchor expectations. We show that...

This paper studies a DSGE model with endogenous financial asset supply and ambiguity averse investors. An increase in uncertainty about financial conditions leads firms to substitute away from debt and reduce shareholder payout in bad times when measured risk premia are high. Regime shifts in...

Most international commerce is carried out by multinational firms, which use their foreign affiliates for the majority of their foreign sales. In this paper, I examine the determinants of multinational firms' location and production decisions and the welfare implications of multinational...

We study the trading dynamics in an asset market where the quality of assets is private information of the owner and finding a counterparty takes time. When trading of a financial asset ceases in equilibrium as a response to an adverse shock to asset quality, a large player can resurrect the...

The standard argument for abstracting from capital accumulation in sticky-price macro models is based on their short-run focus: over this horizon, capital does not move much. This argument is more problematic in the context of real exchange rate (RER) dynamics, which are very persistent. In this...

This paper studies the determinants of optimal taxes for wealthy individuals faced with capital income risk. I develop a model of optimal taxation of capital income in which wealth and income inequality is a result of capital income shocks together with frictions in financial markets. I use the...

Countries in the Euro periphery have gone from zero sovereign spreads and healthy economic growth in 2006 to sovereign debt problems and deep recessions by 2010. This has been accompanied by a transfer of sovereign debts from foreigners to domestic residents and a shift in domestic portfolios...
