This paper develops a model to explain candidates' strategic decisions to provide or withhold information about policy positions in the course of an election campaign. The analysis treats this problem as a game of imperfect information. Attention is focused on modeling voter suspicion of candidates whose positions are ambiguous. Specific numerical examples illustrate that candidate decisions about providing information via informative advertising depend upon candidate policy preferences, campaign fund endowments, partisan reputations, and incumbency status. The model also provides theoretical underpinnings for empirical findings regarding the effects of campaign advertising.  相似文献

After defining scientific forecasting, the crucial role of assumptions in such forecasts is explicated. This is followed by a discussion of the representations upon which forecasting systems are based. Six variables are then introduced to capture differences in socio-political forecasting circumstances: level of detail, accuracy, agreement on problem representation, robustness-brittleness, number of variables and interdependencies, and disturbance. A categorization of forecasting approaches - expert based, Bayesian, extremal statistical, and rule based - is offered. These forecasting approaches are then cross-referenced with the forecasting circumstances to produce recommendations for choosing an appropriate forecasting technique in a given policy circumstance. Most examples in the article are drawn from the realm of foreign policy and international politics, and the cross-referencing section concentrates on foreign energy policy examples.  相似文献

GMI, formerly the General Motors Institute, estabilished a Business and Industry Development (BID) Center in 1983 for the purpose of promoting economic development in Michigan's Flint/Genessee County. BID has had its ups and downs, and is now a going operation. Its experience shows that academic resources can be used to promote regional development. BID has provided an alternative for innovative faculty who are not comfortable with the traditional academic research culture. It is part of a system of business and technical resources, an incubation environment, and available venture capital. For the BID system to work efficiently, however, legislation is needed that would exclude academic institutions from tax liability on income from utilization of their resources and staffs in assisting spinoff and startup companies in developing within their contituencies and communities.  相似文献

If each legislator wishes to encourage other legislators to address new problems in future periods, then a subgame perfect Nash equilibrium can exist with the following properties: (1) no legislator finds it worthwhile to make a narrow proposal that appeals to a minimum majority; (2) instead, legislators propose policies that appeal to all members, not for fear of retaliation, but rather to encourage other members to work on new problems in succeeding periods; (3) in succeeding periods no legislator amends the existing broad policy. We find an equilibrium with these properties in finite as well as infinite period games.  相似文献
