Abstract.  Let Ω be a space of densities with respect to some σ -finite measure μ and let Π be a prior distribution having support Ω with respect to some suitable topology. Conditional on f , let X n  = ( X 1 ,…, X n ) be an independent and identically distributed sample of size n from f . This paper introduces a Bayesian non-parametric criterion for sample size determination which is based on the integrated squared distance between posterior predictive densities. An expression for the sample size is obtained when the prior is a Dirichlet mixture of normal densities.  相似文献

This paper suggests that transactions charges in foreign exchange markets, rather than being solely brokerage fees, represent exchange rate uncertainty in periods of great fluctuations by including remuneration for the assumption of risk by foreign exchange dealers. Since most of the cost of exchange rate uncertainty may be largely endogenously included in the foreign exchange markets, attempts to examine the efficient market hypothesis in these markets should most appropriately include specific consideration of transactions costs. There appears to be empirical support for the premise that transactions charges are positively related to exchange rate risk, and, as well, inclusion of contemporaneous bid-ask spreads into the interest parity schedule leaves few unexplained profits from dollar-pound covered interest arbitrage during the 1970's and underscores the notion of classifying periods by degree of turbulence in analyzing covered interest arbitrage.  相似文献

Rom Harré's generative account of causality has been drawn on heavily by advocates of critical realism. Yet Harré argues that critical realists often exaggerate the extent to which powerful causal explanations of social phenomena can be developed. Certain proponents of critical realism have responded to Harré's criticisms by suggesting that it is useful to consider the relevant issues in relation to the familiar Aristotelian classification of four causes. In this paper I contribute to this debate and pursue a similar strategy. The paper adds to existing contributions in two ways. Firstly, I outline how Harré sees his generative account of causality as linking up with Aristotelian themes. It emerges that Harré at times conceives of his generative theory as part of an alternative to the Aristotelian system while at other times he draws connections between it and a reformulated account of formal causality. Secondly, I argue that when we consider the positions of Harré and proponents of critical realism on the scope of causal explanation in the social realm in relation to the interpretation of final causes offered by another philosopher profoundly influenced by the Aristotelian tradition, namely Charles Peirce, we can see both as limited in certain respects.  相似文献

Using the oil crisis of the late 1970s as a case study, we examine,the intertwined influences of public opinion and media attentionon the credibility of regulatory threats. We focus on threefactors: the intensity of public demands for regulatory intervention,the extent to which there are other competing demands on legislativeattention, and the availability of scapegoats external to theindustry. We use television news coverage of various topicsto measure these three factors. We hypothesize that firms threatenedwith potential regulation restrained price increases, with thelargest and most publicly visible firms exercising the greatestrestraint. We find that large, visible oil firms restrainedprice increases for the most important decontrolled prodicts(diesel fuel oil) when media coverage of the oil industry wasextensive. These firms exercised less restraint when the governmentwas busy with other issues or when political instability inthe Middle East offered an external rationale for oil priceincreases.  相似文献

SPECULATIVE INTENSITY AND SPOT AND FUTURES PRICE VARIABILITY   总被引:1,自引:0,他引:1  
This paper develops a simultaneous stochastic rational-expectations model of futures- and spot-price determination. Using the model, we find that increases in what we term speculative intensity increase spot-price variability arising from storage-cost shocks, but decrease spot-price variability arising from demand shocks. In contrast, increases in speculative intensity unambiguously decrease futures-price variability, regardless of the underlying source of disturbances. We are able to develop these comparative-static results because the model has a unique equilibrium.  相似文献
