For more than forty years, the gravity equation has been a workhorse for cross-country empirical analyses of international trade flows and, in particular, the effects of free trade agreements (FTAs) on trade flows. However, the gravity equation is subject to the same econometric critique as...

The authors examine the relative importance of the growth of physical and human capital and the growth of total factor productivity (TFP) using newly organized data on 145 countries that span more than one hundred years for twenty-four of these countries. For all countries, only 3 percent of...

The authors show that estimated productivities of labor and capital, which rationalize trade flows across countries, are related to total factor productivities, which rationalize output differences across countries. They present evidence that these productivities from trade are related to the...

We examine the relationship between real and financial integration. Real integration is measured by productivities of capital and labor from trade data for 1982 to 1997. Financial integration is measured by the black market exchange rate. We find more evidence of convergence to equality for...
