Evidence is presented regarding strengths and limitations of portfolio approaches as applied to diversifying export earnings. An empirical application using data from Malawi, Tanzania, and Zimbabwe is used to demonstrate these strengths and limitations. Modifications of the typical portfolio approach to export diversification are presented; these modifications help make the approach more plausible for use in developing countries. The modified approach is shown to provide guidance to policymakers who seek simultaneously to increase export earnings and reduce their instability.  相似文献

The United States has faced at times the policy dilemma of seeing conflict erupt between two countries with which it maintains friendly diplomatic relations. The bureaucratic biases of relevant agencies can play an important role in determining whether to choose sides or remain neutral in these conflicts. In the early 1960s the Africa Bureau adopted a pro-Ethiopia bias that shaped American policy in the Horn of Africa. With the insights provided by the 2010 Wikileaks cables, this analysis explores how the “Ethiopia imperative” affected three inter-related American policy decisions in the Horn of Africa in the early twenty-first century: the decision to support Ethiopia despite its refusal to abide by a legally binding decision that favoured Eritrea following the 1998–2000 Eritrea–Ethiopia border war; to give Ethiopia what amounted to a “blank cheque” to invade Somalia in December 2006 and overthrow the Council of Islamic Courts (CIC); and to confront and isolate Eritrea diplomatically for waging proxy war against Ethiopia in Somalia.  相似文献

This paper suggests that “systemic risk” (e.g., of financial market collapse, or of ecological calamity) has a distinctive kind of moral significance. Two intuitive data points need to be explained. The first is that the systematic imposition of risk can be wrongful or unjust in and of itself, even if harm never ensues. The second is that, even so, there may be no one in particular to blame. We can explain both ideas in terms of what I call responsibilities of “Collective Due Care.” Collective Due Care arguably precludes purely aggregative cost‐benefit decision‐making and requires one kind of “precautionary” attitude in public choice.  相似文献

Nation-wide surveys of graduate programs in public administration/affairs support assertions by critics that most programs do not provide students with adequate preparation for coping with information technology. This paper identifies the computer-related knowledge and skills demanded by the contemporary administrative workplace and, after analyzing the sufficiency of current curricula offerings, proposes three goals for education in the use and management of information technology and suggests curriculum revisions necessary to reach these goals. Finally, implementation problems associated with curricula revisions are identified and discussed.  相似文献

Recurring cutbacks in the public sector have received extensiveattention. Most of the emphasis has been on how to adjust to declinein support for public programs. Cutback Management andcon-tracting-out are examples of this approach. This article focuseson the negative consequence of cutbacks. It suggests that inadequateattention is being given to the decrease in the capacity of agenciesto act. An administrative disinvestment is occurring in much the sameway as it has for roads, bridges and other parts of our public infrastructure. Now, we are disinvesting in another critical social asset--our public bureau-cracies. The nature and implictions ofadminis-trative disinvestment are explord.  相似文献
