We estimate a model of urban productivity in which the agglomeration effect of density is enhanced by a metropolitan area's stock of human capital. Estimation accounts for potential biases due to the endogeneity of density and industrial composition effects. Using new information on output per...

We examine the relationship between human capital and economic activity in U.S. metropolitan areas, extending the literature in two ways. First, we utilize new data on metropolitan area GDP to measure economic activity. Results show that a one-percentage-point increase in the proportion of...

In the past sixty years, transistor sizes and weights have decreased by 50 percent every eighteen months, following Moore’s Law. Smaller and lighter electronics have increased productivity in virtually every industry and spurred the creation of entirely new sectors of the economy. However,...

Imports of goods that embody foreign technology raise a country's output directly as inputs into production and indirectly through reverse-engineering of these goods, which contributes to domestic imitation and innovation. This paper first quantifies spillovers from high-technology imports from...

International trade economists typically assume that there are no cross-country differences in industry total factor productivity (TFP). In contrast, this paper finds large and persistent TFP differences across a group of industrialized countries in the 1980s. The paper calculates TFP indices,...

This paper examines the role of skilled labor in the growth of total factor productivity. We use panel data from manufacturing industries to assess the extent to which productivity growth in yearly cross section is tied to industry shares of skilled labor inputs. We find robust evidence that...

Economists, business analysts, and policymakers have all focused considerable attention on U.S. productivity growth in recent years. This paper presents a broad overview of productivity both labor and total factor and discusses why it is such an important topic. We begin with the official U.S....

This paper provides evidence on the extent to which inflation expectations generated by a standard Christiano et al. (2005)/Smets and Wouters (2003)-type DSGE model are in line with what is observed in the data. We consider three variants of this model that differ in terms of the behavior of,...

We estimate a DSGE model where rare large shocks can occur, but replace the commonly used Gaussian assumption with a Student´s t-distribution. Results from the Smets and Wouters (2007) model estimated on the usual set of macroeconomic time series over the 1964-2011 period indicate that 1) the...

We examine the dynamic effects of credit shocks using a large data set of U.S. economic and financial indicators in a structural factor model. The identified credit shocks, interpreted as unexpected deteriorations of credit market conditions, immediately increase credit spreads, decrease rates...
