THE EFFECTS OF OIL AND MIGRATION ON BANANAS, COCOA, COFFEE AND COTTON EXPORTS IN LATIN AMERICA
估计了厄瓜多尔、墨西哥和委内瑞拉主要农产品出口的供给函数，发现石油出口导致的货币升值在1960-70年代大幅减少了农业出口，而世界价格和城乡移民的影响相对较小。
Supply functions are estimated for the principal agricultural exports of Ecuador, Mexico and Venezuela. The domestic price effect is divided into a world price and an exchange‐rate (Dutch‐disease) effect. The exchange‐rate affects both income and foreign exchange payable cost items. Labour costs are introduced through the Todaro migration model. Regression results improve on previous work and suggest that oil‐export‐induced national currency revaluations provoked very substantial reductions in agricultural exports during the 1960s and 1970s. Both world prices and rural‐urban migration seem to have effects comparatively very small, where these effects are present at all.
