Open economy macroeconomics typically takes as exogenously given important aspects of the pattern of international trade. This paper shows how heterogeneity in trade costs and heterogeneity in productivities work together to jointly determine features of the pattern of international trade and...

The path of economic development for rich industrialized countries is typically to transit from farming to manufacturing to services. To do so requires corresponding productivity gains to pull the economy from one sector to the next one. For example, the US and Japan developed their...

Despite the pervasiveness of industry regulation, there are few studies of its impact on industry productivity. Assessing regulation's impact on productivity has been difficult for a number of reasons, including the complexity of regulations and the difficulty measuring productivity. We study an...

We formulate a version of the growth model in which production is carried out by heterogeneous plants and calibrate it to US data. In the context of this model we argue that differences in the allocation of resources across heterogeneous plants may be a significant factor in accounting for...

What is the effect of imports on productivity? To answer this question, we estimate a structural model of producers using product-level import data for a panel of Hungarian manufacturing firms from 1992 to 2001. In our model with heterogenous firms, producers choose to import or purchase...

Researchers have estimated productivity changes surrounding trade liberalization for different countries, using different techniques, and have generally reached the conclusion that gains are positive. In this paper we study how different techniques influence the quantitative results by...

In this paper we document the properties of revisions to macroeconomic data in the US and analyze the implications of these properties in the context of a general equilibrium model. We find that the revisions to major macroeconomic variables such as output and productivity growth are large and...

Shifts in the underlying growth rate of productivity, such as occurred in the 1970s and the 1990s, are relatively rare and difficult to identify in real time. In this paper, we document that economists' projections of trend productivity growth adjust gradually to shifts in trend growth. We find...
