This paper reviews the theoretical and empirical work on allocative efficiency in traditional agriculture and presents a new study of technical efficiency among Tanzanian cotton farmers. The theoretical arguments are shown to apply primarily in a competitive context that differs significantly from that in which peasant farms operate. Re‐analysis of earlier empirical studies shows that, on average, the marginal value products of inputs differ by more than 40 per cent from the marginal factor costs to which they should be equated under allocative efficiency. Our own study among Tanzanian cotton farmers in Geita District reveals that output could be increased by 51 per cent if all farmers achieved those levels of technical efficiency that were in fact achieved by the best farmers in the sample using the same inputs and technologies that the less efficient used. These results indicate that the efficiency hypothesis may not be applicable to much of peasant agriculture and that development policies might fruitfully place more emphasis on raising large numbers of farmers closer to the relatively high efficiency levels achieved by some of their neighbors. 相似文献

Dr. Elizabeth Garrett Anderson (1836–1917), co-founder of the London School of Medicine for Women, and Dame Millicent Garrett Fawcett (1847–1929), leader of the constitutional suffrage movement, were centrally involved in the Victorian and Edwardian campaign for women's equality. Both women attempted to maintain a separation between the suffrage movement and the sexualized realm of the female body, which was subject to state intrusion during the debates over the Contagious Diseases Acts and again during the force-feeding of imprisoned suffragettes some forty years later. But the Garretts had to negotiate the intersection of gender, class, and sexual politics in order to advance the cause of feminist social reform. 相似文献

Americans' confidence in government is low by historical standards. We fielded a national telephone survey to examine influences on government confidence and whether public discontent was affected by altering the salience of specific government operations. We used a question order experiment where we alternated between first asking a general question about confidence in government and first asking about confidence in specific government operations. We found that posing the specific policy questions first elevated general confidence more than the reverse. The largest and most noticeable effects were observed for
Republicans
and those most knowledgeable and attentive to politics. Findings of context effects and the partisan subgroup differences are consistent with existing theories on public opinion change as well as with previous question order experiments. But, evidence that the cognitive elite was especially influenced by question order challenges previous theories that presumed that its sophistication made it immune to influence. We suggest that education and political knowledge expand rather than contract the opportunities for priming. 相似文献

Comparative political science has largely ignored the marked cross-national variation in Green party electoral performance. This article uses a unique aggregate dataset of 347 parliamentary elections from 32 countries over the course of 45 years to test competing theories about the causes of Green party success. The findings show that voter demand, institutions and mainstream party strategy all affect the Green vote. Green parties do well in societies with post-materialist conflicts caused by high levels of wealth or the presence of a tangible environmental dispute. The article also shows that regional decentralisation helps Green parties, but electoral systems have little effect on their vote share. Most importantly, it demonstrates that the impact of mainstream party strategy on Green electoral strength is dependent on the age of the Green party. While mainstream parties can undermine young Green parties by adopting the environmental issue, this effect is reversed once the Greens have survived a number of elections. Thus ‘accommodative’ mainstream party strategies eventually boost the Green vote by increasing the salience of the key Green issue. 相似文献

What is the relationship between voting and individual life satisfaction in Latin America? While studies of Western Europe suggest that voters are happier than nonvoters, this relationship has not been explored in the younger democracies of the developing world, including those of Latin America. Using multilevel regression models to examine individual‐level survey data, this study shows a positive correlation between voting and happiness in the region, noting, however, that the relationship is attenuated in those countries that have enforced compulsory voting. We then explore the causal direction of this relationship: while the existing literature points to voting as a possible determinant of individual happiness, it is also possible that happier individuals are more likely to vote. Three different strategies are used to disentangle this relationship. On balance, the evidence suggests that individual happiness is more likely to be a cause rather than an effect of voting in Latin America. 相似文献
