Evidence and Implications of Non-Tradability of Food Staples in Tanzania 1983-98
研究发现坦桑尼亚大部分地区的主食不可贸易，导致货币贬值无法提高国内产出价值，限制了宏观调整策略的效果。
Economic reform programmes assume that major goods are tradable, such that depreciation of the real exchange rate raises the value of output compared to factor costs in domestic currency. In Tanzania, major food staples that account for most real income are non-tradables in at least one-quarter of the country. This conclusion is demonstrated and the implications are assessed for the constraints imposed on macroeconomic-led adjustment strategies.
