Pooling consumption data from different countries for demand system estimation is attractive because it increases both sample size and therange of v ariation of relative prices and income. The major objection to pooling is that d ifferent countries may have different demand system parameters. This paper propo sed and estimates specifications that permit pooling while allowing both short-r un andlong-run demand systems to differ across countries. Using data from Belgi um, the United Kingdom, and the United States, the authors findthat, although p ooling was accepted for some pairs of countries and some specifications, it was rejected for most. They conclude that caution is appropriate in pooling internat ional consumption data. Copyright 1987 by MIT Press.
