The simple gravity equation explains a great deal about the data on bilateral trade flows and is consistent with several theoretical models of trade. We argue that alternative theories nevertheless predict subtle differences in key parameter values, depending on whether goods are homogeneous or...

We develop a procedure to rank-order objects using censored panel data sets. We illustrate this by ranking countries and commodities using disaggregated American import data and find evidence that countries and commodities can be ranked. Countries habitually begin to export goods to the United...

We develop a procedure to rank-order countries and commodities using dis-aggregated American imports data. We find strong evidence that both countries and commodities can be ranked, consistent with the "produce cycle" hypothesis. Countries habitually begin to export goods to the United States...

This paper describes data on U.S. exports from 1972-1994, classified according to the Schedule B' system, Harmonized System (HS), Standard International Trade Classification (SITC, Revisions 2 and 3), and Standard Industrial Classification (SIC, 1972 basis), along with various concordances. All...

Researchers constructing index number frequently face the problem of new (or disappearing) goods, for which the price and quantity are not available in some periods. In theory, the correct way to handle a new good is to treat its price before it appears as equal to the reservation price (i.e.,...

We evaluate the endogenous growth hypothesis using sectoral data for South Korea and Taiwan. Our empirical work relies on a direct measure of the variety of products from each sector which can serve as intermediate inputs or as final goods. We test whether changes in the variety of these inputs,...

The purpose of this paper is to identify conditions under which hedonic price indexes provide an exact measure of consumer welfare, so that the welfare effects of quality change can be inferred. Our results are quite positive in providing a rational for existing practices, though the conditions...

Dooley et al (2003, 2004a,b,c) argue that China seeks to raise urban employment by 10-12 million persons per year, with about 30% of that coming from export growth. In fact, total employment increased by 7.5-8 million per year over 1997-2005. We estimate that export growth over 1997-2002...
