The share of merchandise output that is internationally traded has significantly increased while tariffs have fallen. However, standard trade models have surprising difficulty linking these two facts. Trade growth slowed in the 1970s as tariffs fell relatively sharply while after the late 1980s...

Many applications in economics use multi-sector versions of the growth model. In this paper, we measure the income shares of capital and labor at the sectoral level for the U.S. economy. We also decompose the capital shares into the income shares of land, structures, and equipment. We find that...

We ask how barriers to international trade affect TFP when there are monopoly rights in the import--competing industries. Holmes and Schmitz (1995) show that without barriers to trade TFP in these industries is as large as possible. We study the general case of finite barriers to trade. We find...

It is well known that if there are mild sector-specific externalities, then the steady state of the standard two-sector real business cycle model can become indeterminate and endogenous business cycles can arise. We show that this result is not robust to the introduction of standard...

In poor countries, labor productivity in agriculture is considerably lower than in the rest of the economy. We assess whether this well known fact implies that labor is mis-allocated between the two sectors. We make several observations that suggest otherwise. First, the same fact holds for US...
