Coca Dollars and the Dollarization of South America
利用玻利维亚古柯种植区非正式贷款市场的独特数据，发现贷款在古柯主要收获季节更可能以美元计价，表明美元化与古柯产业相关，对古柯或可卡因重要产业的国家有启示。
A unique data set on the informal loan market in a coca-growing region of Bolivia is used to explore the hypothesis that the dollarization of this market is related to the coca industry. Implications are then drawn for other nations where coca or cocaine is an important industry. The authors find that loans are significantly more likely to be denominated in dollars in the season of the major coca harvest than at any other time of the year. The effects of the term and size of loans is consistent with the financial needs of the drug industry, which is highly dollarized. Copyright 1991 by Ohio State University Press.
