For richer, for poorer: marriage and casualized sex in East African artisanal mining settlements

Migrants to Tanzania's artisanal gold mining sites seek mineral wealth, which is accompanied by high risks of occupational hazards, economic failure, AIDS and social censure from their home communities. Male miners in these settlements compete to attract newly arrived young women who are perceived to be diverting male material support from older women and children's economic survival. This article explores the dynamics of monogamy, polygamy and promiscuity in the context of rapid occupational change. It shows how a wide spectrum of productive and welfare outcomes is generated through sexual experimentation, which calls into question conventional concepts of prostitution, marriage and gender power relations

Specifically, the report discusses: (1) The relative importance of different types of traders and trading on the board of trade, (2) the volume of trading at different rates of commission, (3) the volume of trading by members and nonmembers of the board, (4) the amount and source of commission income to brokerage firms, (5) the relative importance of different types of brokerage firms, and (6) the structure of the board and the operating practices of its members. Special financial and trading data were developed for this study to supplement data already available in the Commodity Exchange Authority (CEA) and other agencies of the U.S. Department of Agriculture. At the request of the CEA, the Chicago Board of Trade asked each member of the Board of Trade Clearing Corporation to supply information on volume of trading by type of trade and at different rates of commissions and fees during selected weeks in March and May 1972
