Book excerpt: Nontariff Measures and International Trade includes 20 chapters authored by John Beghin and co-authors over the last 20 years on the economics of quality-standard like nontariff measures in the context of international trade. This book provides a coherent and comprehensive treatment of these nontariff measures, from their measurement to their effects on trade and welfare. In Part I, the authors use different perspectives to make the case that, unlike tariffs, quality-standard like nontariff measures are complex to measure and analyze and do not easily lead to general policy prescriptions. Then, Part II contains contributions on measurements of welfare and trade effects of nontariff measures, accounting for potential market imperfections. Part III presents chapters on the potential protectionism of nontariff measures when they are used to favor some economic agents over society. The last part presents cases studies of nontariff measures in different industries, markets, and countries.
