This essay uses time‐series data on cocoa plantings in Western Nigeria to re‐examine some popular conclusions about the price responsiveness of farmers in underdeveloped economies. Annual variations in the rate of planting were found to be more closely related to farmers’ income from cocoa sales than to current price. Qualitative evidence suggests that longer‐term trends in cocoa plantings were also influenced by changing opportunity costs and by the institutional structure of rural factor markets. These results cast some doubt on commonly accepted capital stock adjustment models of investment in tree crops, which assume that farmers rely heavily on forecasting future price trends when deciding how much to plant. Given the uncertainty of future crop prices, it seems more likely that farmers plant more trees when they can afford to do so, so long as opportunity costs are not prohibitive.  相似文献

In 1993 President Clinton signed into law the National and Community Service Trust Act, the centerpiece of which was a new national service initiative—AmeriCorps. The overall purpose of AmeriCorps was to promote community building through volunteer service. AmeriCorps was one high-profile program established in part to highlight government-nonprofit partnerships and their capacity to improve communities and service delivery to the most vulnerable in communities—poor children, frail elderly, and teenagers who are at risk of dropping out of school or getting into serious juvenile delinquency problems. AmeriCorps' programs nationally work to achieve three goals—Getting Things Done, Member Development, and Strengthening Communities. Few of the studies on AmeriCorps have explicitly studied their impact on community strengthening. This article reports on a two-year study of twenty two AmeriCorps programs in Florida from 1997–2000, emphasizing their objectives and success in community strengthening. Program results are limited. The programs increased the number of volunteers delivering their services and developed one or more community partner organizations at each site. Nearly all of the program staff and community partners believed that the AmeriCorps programs positively influenced the community's self-help capacity to some extent. However, data indicating broader community strengthening impacts were hard to find and difficult to track. Reasons for this relatively modest impact on broader community strengthening goals are articulated based on surveys, interviews, and site visits.  相似文献

Parliamentary websites (PWs) can potentially enhance the quality of government by providing information and communication links that stimulate political awareness, deliberation and participation. This article focuses on two particular uses of PWs that can facilitate communication between constituents and their Members of Parliament: provision of MP contact and background information; and links to social media. Through a seminal empirical examination of all 184 functioning lower house and unicameral PWs around the world, this study found that although PWs in wealthy democracies generally provide more MP information, the majority of PWs are deficient in providing basic MP information to citizens and utilizing linkages to social media. By contrast, some non-democratic states and newly democratized countries, especially those with compulsory voting, display a relatively high level of MP transparency and social media connectivity.  相似文献

Abstract

Gentrification is a procyclical process by which certain inner‐city neighborhoods are revitalized to meet the demands of professional households. It is confined to cities with substantial central business district office growth and with housing markets characterized by substantial suburb‐to‐inner city filtering. The process remains limited in scale, and available data do not permit a judgment as to whether changes in mortgage lending have changed the nature of the process.  相似文献

In today's brave new world, women who suffer the loss of their husband or lover can call upon medical science to create a souvenir baby. The rights of the decedent over his genetic material and the rights of the child who is created therefrom are the subject of an evolving legal process. This Essay examines legal, moral and ethical issues which arise from post-mortem artificial insemination. It discusses the attendant conflicts of procreative rights, finality of probate, psychological issues, international law, and recent cases. Ultimately, comprehensive legislation must be enacted to address these issues.  相似文献
