Abstract
Michael Pelcovits (1979, p. 307) recently showed that with an unstable foreign excess supply curve, either a fixed quota or a buffer stock program with a fixed tariff can be used to stabilize domestic price at a given level, and both policies 'will have the same effect on social welfare [so...t]he choice between [the two...] must then be made on the basis of administrative cost and feasibility'. However, he reached his conclusion by ranking the two policies on the basis of domestic welfare, and in this note we demonstrate with his same model that on the basis of foreign welfare the buffer stock is better than the quota. Thus, world welfre is higher under the buffer stock than under the quota. © 1981.

Edward Tower
Professor Tower specializes in finance, computable general equilibrium modeling, macroeconomics, development economics, microeconomics, and managerial economics. He conducts a majority of his research within the study of trade and development, exploring a variety of variables from tariffs, quotas, and time zone arbitrage, to equities, mutual funds, and index mutual funds. Since he began publishing his work in 1965, he has contributed over 130 articles to leading academic journals and has had several books, chapters, and papers appear in print. Some of his more recent writings include, “School Choice: Money, Race, and Congressional Voting on Vouchers,” completed in collaboration with O. Gokcekus and J. Phillips; “Rational Pessimism: Predicting Equity Returns by Tobin’s q and Price/Earnings Ratio” with M. Harney; and “Predicting Equity Returns for 37 Countries: Tweaking the Gordon Formula” with K. Reinker. Much of his work pertaining to U.S. trade policy has been used to determine congressional voting on protectionist issues based on campaign contributions. His work on financial issues has also played an important role in determining the value of the U.S. stock market. His latest studies involved an investigation of congressional voting on importation of ethical drugs and predicting returns on both foreign and U.S. equity.
