This paper establishes a new empirical finding: the degree of labor intensity and the degree of price flexibility are negatively correlated across industrial sectors in the U.S. economy. This finding suggests that varying factor intensity can potentially generate different degrees of price...

This paper focuses on the role of small models in macrodynamics. It discusses the insights that I believe these models offer and the extent to which they can address some of the complex issues, such as heterogeneity and interactions among agents that are receiving increasing attention in the...

Which are the main frictions and the driving forces of business cycle dynamics in an open economy? To answer this question we extend the standard new Keynesian model in three dimensions: we incorporate financing frictions for capital, employment frictions for labor and extend the model into a...

Recent empirical research has documented that the state of the limit order book influences stock investors' strategies. Investors place more aggressive orders when the same side of the order book is thicker, and less aggressive orders when it is thinner. We conjecture and demonstrate that this...

A special characteristic of the patent system is that it features multiple patent-policy levers that can be employed by policymakers. In this note, we develop an R&D-based growth model to analyze the optimal mix of patent instruments by considering patent breadth and the division of profit in...

Increasing financial integration challenges the optimality of inward-looking strategies for optimal monetary policy. Those issues are analyzed in an open economy where foreign net lending, and the current account, are determined by a collateral constraint. Durables represent collateral. The...

Recent research developments in common-pool resource models emphasize the importance of links with ecological systems and the presence of non-linearities, thresholds and multiple steady states. In a recent paper Kossioris et al. (2008) develop a methodology for deriving feedback Nash equilibria...

The quantitative significance of shocks to the financial intermediary (FI) has not received much attention up to now. We estimate a DSGE model with what we describe as chained credit contracts, using Bayesian technique. In the model, credit-constrained FIs intermediate funds from investors to...

We study equity price volatility in general equilibrium with news shocks about future productivity and monetary policy. As West (1988) shows, in a partial equilibrium present discounted value model, news about the future cash flow reduces asset price volatility. We show that introducing news...

We analytically solve the portfolio choice problem in the presence of wash sale constraints in a two-period model with one risky asset. Our results show that wash sale constraints can heavily affect portfolio choice of investors with unrealized losses. The trading behavior of such investors is...
