Production technologies in Ethiopian agriculture
利用1989-90年农户数据，研究埃塞俄比亚农业中使用和不使用化肥两种生产技术的特征与选择，发现化肥使用受政治因素影响，且化肥改变了生产要素的分配，同时无化肥农场规模过小。
Abstract This article examines the characteristics of and choice among two production technologies in Ethiopian agriculture, one with fertilizer and the other without, using 1989–90 farm‐level data. For northwest and central Ethiopia, fertilizer usage determinants are estimated simultaneously with technology‐specific production functions. For southern Ethiopia, where fertilizer is rarely used, a single production function is estimated. Three conclusions emerge. First, fertilizer use is not significantly affected by a farm's stocks of capital or land. This is consistent with the fact that fertilizer allocation decisions under the deposed Mengistu regime were politicized to the point where farmers had little control over use. Second, fertilizer is associated with a smaller factor share for cattle and a larger share for land, meaning that those who control land may gain relative to the individual farmers who own cattle as the country develops agriculturally. Third, farms without fertilizer in northwest and central Ethiopia tend to be too small, a problem due to population pressures on the land and communal methods of land allocation. This suggests that land allocation institutions should adjust by distributing land to a smaller but more economically viable number of farmers.
