One of the main purposes of our studies of U.S.-based multinational firms has been to examine the relationship between direct investment by U.S. firms and the export trade of the United States, a subject of bitter controversy for at least the last fifteen years. Changes over time in trade flows...

Measures of long term trends in world export prices of manufactured goods and in the terms of trade between manufactured goods and primary products are sensitive to the choice of country weights and of base periods and, most important of all, the treatment of quality change. Later base periods...

We measure export participation rates in the U.S. manufacturing sector using a new administrative dataset and compare them to participation rates constructed from the commonly used Census of Manufacturers (CM). Both at the establishment and firm level export participation rates are near 40...

If international trade is strictly trade in intermediate goods, would the common presumption, that small, less developed economies (the South) lose from trade wars still be true? We address this question by constructing a dynamic general equilibrium model in which the North and the South trade...

The importance of new technologies derives from the fact that they spread across many different users and uses, as well as different geographic regions. The diffusion of technological improvements, across producers within a country and across international borders, is critical for long run...

This paper considers the observational implications of social influences on adoption decisions for an environment of perfect foresight adopters. We argue that social influences can produce two observable effects: 1) discontinuities in unconditional adoption curves and 2) pattern reversals in...

The adoption and diffusion of technological knowledge is generally regarded as a key element in a country's economic success. However, as is the case with most types of information, the transfer of technological knowledge is likely to be subject to adverse selection problems. In this paper we...

Unlike the widespread adoption of information and communications technology (ICT) in much of the economy, adoption of ICT in clinical care is limited. We examine how a number of not previously emphasized features of the health care and ICT markets interact and exacerbate each other to create...

Estimation of our model for a sample of 19 technologies, 21 countries, and the period 1870-1998 reveals that embodied productivity growth is large for many of the technologies in our sample. On average, increases in the variety of vintages available is a more important source of growth than the...
