Three of the most important recent facts in global macroeconomics — the sustained rise in the US current account deficit, the stubborn decline in long run real rates, and the rise in the share of US assets in global portfolio — appear as anomalies from the perspective of...

This paper studies the long-run effects of anticipated inflation on output and welfare within a search-theoretic framework. We allow money-holders to choose the intensities with which they search for trading partners, so the frequency of trades is endogenous. We consider the standard pricing...

Most economic activity occurs in cities. This creates a tension between local increasing returns, implied by the existence of cities, and aggregate constant returns, implied by balanced growth. To address this tension, we develop a theory of economic growth in an urban environment. We show how...

Since 1975, the aggregate value of residential land has averaged approximately 90% of GDP and has recently risen to 125% of GDP. In this paper, I use a calibrated general-equilibrium model with idisyncratic labor productivity draws to attempt to measure the extent to which current tax policies,...

All industrialized countries experienced a transition from high birth rates and stagnant standards of living to low birth rates and sustained growth in per capita income. What contributed to this transformation? Were output and population dynamics driven by common or separate forces? We develop...

This paper explores equilibrium theory of wealth accumulation and wealth inequality when entrepreneurs have collateral constraints and are subject to idiosyncratic productivity shocks. The model is an extension of Kiyotaki-Moore's setting to incorporate shocks and, at the same time, is a version...

The purpose of this paper is to develop a framework that allows one to distinguish between the extent to which differences in firm productivity are intrinsic and the proposition that higher paying firms employ more able workers. For this purpose, we adapt the equilibrium stochastic model of firm...

Housing economists have questioned whether current US tax and government mortgage policy actually fosters homeownership. In this paper we examine this question interms of a dynamic general equilibrium model with heterogeneous agents. The model allows households to make saving and shelter...

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...
