Sampling equilibrium, with an application to strategic voting   总被引:1,自引:0,他引:1  
We suggest an equilibrium concept for a strategic model with a large number of players in which each player observes the actions of only a small number of the other players. The concept fits well situations in which each player treats his sample as a prediction of the distribution of actions in the entire population, and responds optimally to this prediction. We apply the concept to a strategic voting model and investigate the conditions under which a centrist candidate can win the popular vote although his strength in the population is smaller than the strengths of the right and left candidates.  相似文献

This article proposes a new forecast combination method that lets the combination weights be driven by regime switching in a latent state variable. An empirical application that combines forecasts from survey data and time series models finds that the proposed regime switching combination scheme performs well for a variety of macroeconomic variables. Monte Carlo simulations shed light on the type of data‐generating processes for which the proposed combination method can be expected to perform better than a range of alternative combination schemes. Finally, we show how time variations in the combination weights arise when the target variable and the predictors share a common factor structure driven by a hidden Markov process.  相似文献

Conclusion These very positive gains in economic well-being for certain categories of black families do not surprise us. Those in which the head is under 35 and live in the North and the West have had relatively more opportunity open to them as a result of some of the strong enforcement policies of the late sixties and affirmative action programs. This group of the black population, by and large, is better educated, more mobile, and more job-ready. It is, therefore, in a position to be more productive and thereby earn relatively higher incomes when society relaxes some of its discriminating tendencies. No such advantages, however, are available to the households headed by females or older households which comprise the overwhelming members of families in poverty.  相似文献

Allan W Shearer 《Futures》2004,36(8):823-835
Describing the evolution of possible futures in the narrative form is widely practised. However, while stories are intuitively recognized, the ability to compose a comprehensible story is often difficult. Ambiguities or inconsistencies within a scenario-as-story are not simply aesthetic faults, but are failings which can weaken the use of the technique in a learning or decision-making process. This paper provides a working understanding of narrative as a particular kind of knowledge and proposes an adaptation of Kenneth Burke’s Dramatic Pentad as a way to explicitly capture this kind of knowledge within a scenario construction process.  相似文献

China's sustained rapid economic growth and development has contributed to the surge in consumption and production of livestock in that country  termed the livestock revolution. Consumption trends are first reviewed, and changes in food consumption patterns include a marked shift away from grains and towards meats and dairy products. A question is to what extent this rapid increase in demand for livestock products is reflected in China's agri‐food trade statistics? While her agri‐food imports have dramatically increased since China's accession to the WTO, livestock products have not made a noticeable contribution, although the import of certain animal feedstuffs has. This implies China's continuing self‐sufficiency in most livestock products. The paper next considers developments in China's livestock farming sector and policies that have been contributing to these supply‐side developments. The paper concludes with an examination of issues that may be important to the future development of China's, and the world's, livestock situation;  this includes future demand developments, and the question of whether future demand growth in China might be met with local production, imports of final product, and/or imports of feedstuffs.  相似文献

Fresh Juice Incorporated (FJI) is in the process of determining whether it should launch a new fruit juice, Genetically Enhanced (GE) Juice. The GE Juice meets consumers' demands for a tasty, nutritious product and it would be the first new juice product in the last fifteen years. Before FJI decides to launch GE Juice, it must analyze the uncertainty surrounding market size, market share, and price of GE Juice. Finally, if FJI decides to launch GE Juice, then they must decide if they will bottle the juice themselves or outsource this process. This case teaches students how to discuss the strategic implications of launching a new product and develop a net present value and financial feasibility simulation model given limited information.  相似文献

Affinity marketing collaboration is a growing practice in the marketplace, yet theories to explain its influence are scarce in the literature. This study suggests two complementary cause-related effects stemming from an organization's connection with its members to explain the underlying mechanism of affinity marketing. The convergent findings of a survey and an experiment reveal that the responses of consumers in affinity marketing are both empathetic and particularistic. These characteristics distinguish affinity marketing from general commercial co-branding and from cause-related strategies which call for sympathetic and altruistic responses. These effects are more pronounced among individuals with a high interdependent orientation in collectivistic cultures. The dual influence of these effects makes affinity marketing an ideal marketing strategy for improving customer loyalty in the more interdependent societies in Asia.  相似文献
