The emigration analysis involves Thai workers and sex workers to Japan, Taiwan, Germany, and other destinations; the immigration analysis focuses on cheap labor trafficked in from Burma during the period 1994-95. After profiling the setting for labor migration across countries, the paper provides an overview of transnational emigrants from Thailand, followed by a discussion of the economic value of Thai emigrants to the Thai economy as well as the economic value to the recipient countries of Japan, Germany, and Taiwan. Other sections of the paper provide data on Thai emigrants to Japan who become manual workers and sex workers, as well as the trafficking in women to Japan. Also discussed are a system of indentured labor in Japan, Thai prostitutes in Germany, Thai prostitutes in the United States, Thai unskilled workers in Taiwan, as well as immigrant workers and Burmese prostitutes in Thailand. The earnings from human trafficking are estimated, along with the social cost of transnational migration. Suggestions are offered for combating international trafficking in women. Appended case studies of Thai prostitutes in Japan, 7 tables, and 29 notes
