This paper argues that it is necessary to allow for country-pair heterogeneity when using the gravity model to estimate international trade flows. We propose and estimate a fixed-effects model that eliminates the heterogeneity bias inherent in standard methods. Further, we show that there is no...

This paper examines the spatial interaction of neighboring cities over their employment cycles. The cycles of neighboring cities tend to be more similar to one another than are those of non-neighboring cities, although this is due primarily to neighbors' tendency to be in the same state. In...

This paper reconsiders recent empirical evidence found by Andrew Rose that countries adopting a common currency will triple their bilateral trade. We find that this large estimated effect is due to estimation bias arising from missing and/or misspecified time-invariant factors, rather than to...

This article reexamines and extends the literature on the use of migration rates to estimate compensating differentials as measures of regional quality of life. I estimate an interregional migration regression for the UK and use the results to measure regional quality of life and standard of...

There is a well-established literature finding that the Canada-U.S. border has a large dampening effect on trade, is asymmetric, and differs across provinces. In this paper, I demonstrate that the standard gravity model used to obtain these results provides biased estimates of the volume of...

This study finds that NAFTA has increased U.S. merchandise exports to Mexico and Canada by just over 15 percent, and has increased total U.S. merchandise exports by nearly 8 percent. We also find that although many states have seen large increases in exports to both Mexico and Canada, others...

There is a great deal of variation in the levels of entrepreneurship, or rates of self-employment, across the regions of Britain. Over the period 1983-1995, average self-employment in the North, Scotland, and the West Midlands was respectively 25%, 15%, and 15% lower than the national average,...

Debates over the desirability a preferential trading area (PTA) begin with the supposition that it will have two effects on the volume of trade: it will increase trade between PTA members, and decrease trade between members and non-members. This paper demonstrates, however, that at the regional...

Despite the ongoing worldwide trend toward regional integration, Japan has remained outside of all regional trading agreements. Because more than 60 percent of Japan's trade is with countries that are members of a major regional bloc, this reluctance may have had significant effects on its...

This paper presents a model of legal migration from one source country to two host countries, both of which can control their levels of immigration. Because of complementarities between capital and labor, the return on capital is positively related to the level of immigration. Consequently, when...
