The chapters are authored by experts from within Latin America and also from Latin America research institutes elsewhere. The book combines practical policy significance with insightful causal and prescriptive generalizations. The emphasis is on the role of governmental decision-making and the important (but secondary) role of the marketplace, social groups, and engineering.
