We consider the optimal wagers to be made by a gambler who starts with a given initial wealth. The gambler faces a sequence of two-outcome games, i.e., “win” vs. “lose,” and wishes to maximize the expected value of his terminal utility. It has been shown by Kelly, Bellman, and others that if the terminal utility is of the form log x, where x is the terminal wealth, then the optimal policy is myopic, i.e., the optimal wager is always to bet a constant fraction of the wealth provided that the probability of winning exceeds the probability of losing. In this paper we provide a critique of the simple logarithmic assumption for the utility of terminal wealth and solve the problem with a more general utility function. We show that in the general case, the optimal policy is not myopic, and we provide analytic expressions for optimal wager decisions in terms of the problem parameters. We also provide conditions under which the optimal policy reduces to the simple myopic case. © 1997 John Wiley & Sons, Inc. Naval Research Logistics 44: 639–654, 1997  相似文献

在军队改革的大环境下,军事训练从难从严向实战化聚焦将成为日常训练的常态,而体能训练就是其中最为基础和重要的训练。但是,现阶段的军事体能训练仍然存在着训练理论不系统、训练方法不科学、相关心理指导和心理训练缺乏等弱点,从而造成体能训练成绩提升缓慢、训练损伤居高不下的问题。本文运用功能性军事体能训练和心理训练相结合的方法,从新兵体能训练着手,对其进行身心干预,旨在增强心理适应能力、提高训练成绩、减少训练损伤,为提高部队实战化训练水平打下基础。  相似文献

How much mileage can we get out of prospect theory to explain foreign policy decision-making? To answer this question, we first argue that risk as outcome uncertainty is the appropriate definition in prospect-theoretical applications. Then, we indicate that probability weighting—a crucial component of prospect theory—is typically ignored in such applications. We argue why this is problematic and suggest how to move forward. Next, we discuss how to establish the reference point in the face of outcomes in multiple dimensions, as is typically the case in foreign policy decision-making. Finally, we discuss what we have learnt regarding prospect theory’s scope conditions and the differences across individuals in the theory’s applicability. Overall, our contribution lies in identifying several underexposed or neglected issues (e.g., the definition of risk and probability weighting), in examining the advancements regarding prospect theory’s scope conditions, and in discussing avenues for further research.  相似文献

Economic freedom has increased living standards worldwide. Concurrent with such gains are rising concerns about potential human costs associated with free markets. This paper uses data on human trafficking and anti-trafficking policies, in conjunction with a measure of economic freedom, to examine whether free markets exacerbate or attenuate the incidence of human trafficking and policies designed to combat it. We do not find evidence suggesting that economic freedom is associated with human trafficking. In addition, our results suggest that economically free countries are more likely to enact and enforce policies to fight human trafficking.  相似文献

Since the 2003 war in Iraq, private military and security companies (PMSCs) have become increasingly legitimate actors in modern conflicts. Despite this normative shift, rumours in March 2015 regarding the use of South African mercenaries in Nigeria to combat Boko Haram insurgents caused an international outrage, while the Nigerian government remained nonchalantly silent on the matter. This article investigates the impact of mercenaries on the conflict in the last six months of the Jonathan government. Using primary and secondary qualitative research, it assesses the role that PMSCs played in Nigeria’s counterinsurgency strategy, along with the ensuing reaction of international and local media to the outsourcing of violence to foreign companies. The article concludes that – notwithstanding the improved image of PMSCs in the world, and the actual impact of the contractors on the Nigerian counterinsurgency effort – the stigma of mercenaries continues to plague the industry, particularly on the African continent.  相似文献
