The article examines the issue of priority setting in Third World agricultural research organizations, for those research sectors and topics which—mainly because of the difficulty of quantifying benefits—are outside the domain of economic surplus and benefit/cost techniques. The issue is redefined as one of processing ill‐structured decisions, i.e., decisions in which there is no unique, identifiable, objectively optimal solution. The implications of this for the concept of rational action in this field are explored, and the results used to define a practical approach. This centres on a radical review of the possible options and criteria in priority setting, using four techniques (challenge groups, repertory grid, creativity techniques and flow charting). The final section of the article examines the decision‐making aspects of these techniques in three priority‐setting contexts of increasing difficulty: within a department, where the issue is essentially one of technical choice between competing research lines; within a major institute or research sector, where there is substantial competition for resources; and in an institute or sector which is facing a crisis of resources or relevance.

This article argues that it is rational for the executive to target resources in space and through time if it seeks to maximise its chances of electoral success. In majoritarian democracies such as the United Kingdom, there are particularly strong incentives to target resources to marginal legislative constituencies, although similar opportunies exist in other political systems. The benefits of such a practice could be growing, because the costs of forms of temporal targeting predicted by theories of the political business cycle have increased, owing to the effect of the global economy. In the United Kingdom one channel through which resources can be targeted is central grants to local authorities. This model is tested with pooled cross-section data on the central finance of English local government between 1981/1982–1995/1996. The article confirms that central government spatially targeted marginals after 1988/1989 while it continued to allocate greater funds near national elections, conditional on its opinion-poll ratings. Hypotheses from the literature on distributional politics are also tested, finding evidence for the temporal allocation of resources to win local elections.  相似文献

Abstract

A number of studies have investigated when parties change their policy positions. However, this growing body of research has had limited interaction with the literature on issue competition. To bring these two perspectives together, this article investigates how and when parties adjust their respective policy positions on immigration, the environment and the welfare state. In the article it is argued that especially large parties in electoral terms adjust their policy positions on specific issues in response to changes in the party system saliency of these issues. When the other parties increase their focus on a given issue, large parties adjust their position in the direction preferred by a majority of the voters. In the article this argument is investigated empirically, based on CMP data from 18 West European countries from 1980 to 2014. The findings largely support the argument and show a strong potential for further integration of the two dominant perspectives on party competition.  相似文献

Unlike the US Chapter 11, the Belgian reorganization legislation requires that distressed firms remain temporarily under court-supervision during the post-confirmation stage. Using a hand-collected sample of firms, we analyze the likelihood of business failure and the time to failure during this period. Less viable firms are more likely to fail and do faster so, indicating relatively effective reorganization proceedings. Firms that are indebted to highly secured banks or owe high sums of unpaid taxes are more likely to fail. Judicial discretion affects the likelihood of failure only in a subsample of sole proprietorships.  相似文献

Duff offered an argument for the conclusion that just or legitimate punishment of socially deprived offenders in our unjust society is impossible. One of the claims in his argument is that our courts have the standing to blame an offender only if our polity has the right to do so since our courts are acting as the representatives of, or to use the exact phrases by Duff, “in the name of”, or “on behalf of”, the whole polity. In this paper I will challenge that claim. I will argue that the courts can be seen as acting, not on behalf of the whole polity, but only on behalf of a subset of its citizens, namely, the just citizens (i.e. the citizens who cannot be seen to have wronged the deprived offenders).  相似文献
