US and Mexican researchers in political science and economics began a research project with an April 1997 workshop at Georgetown University. Recognizing that the North American Free Trade Agreement is too recent, and the lack of a generally accepted theory of integration currently prevented an interpretive synthesis of its effects, they have assembled some descriptive studies that could contribute to such a synthesis when it does become possible. The ten studies cover society, economy, and demography; and government, politics, and public opinion. They are not indexed. Annotation copyrighted by Book News, Inc., Portland, OR
