The general design for the real-time electricity market presented in this paper optimizes and prices both real and reactive
power simultaneously in an AC setting, where all assets—generation, load and transmission—are allowed to bid and are financially
settled at the locational price times energy consumed or produced. The result is that transmission lines are compensated for
both capacity and admittance, providing incentives for efficient operation of transmission-related assets such as FACTS devices,
if price-taking behavior is assumed. Losses are incorporated into the design and become an operating cost for transmission.
The market design is shown to be revenue neutral and, under some assumptions, nonconfiscatory.

Bayesian MCMC Mapping of Quantitative Trait Loci in a Half-sib Design: a Graphical Model Perspective
N.A. Sheehan B. Gulbrandtsen M.S. Lund D.A. Sorensen 《Revue internationale de statistique》2002,70(2):241-267
Graphical models provide a powerful and flexible approach to the analysis of complex problems in genetics. While task-specific software may be extremely efficient for any particular analysis, it is often difficult to adapt to new computational challenges. By viewing these genetic applications in a more general framework, many problems can be handled by essentially the same software. This is advantageous in an area where fast methodological development is essential. Once a method has been fully developed and tested, problem-specific software may then be required. The aim of this paper is to illustrate the potential use of a graphical model approach to genetic analyses by taking a very simple and well-understood problem by way of example. 相似文献

This paper addresses two very old issues in human society: espionage and double crossing. Our major conclusion points out that there will be a serious over rewarding problem in the direct mechanism due to double
crossing in espionage, and a competitive mechanism with a relative performance regime can possibly mitigate the over rewarding
problem and still extract the information.

We extend Condorcet’s Jury Theorem (Essai sur l’application de l’analyse à la probabilité des décisions rendues à la pluralité
des voix. De l’imprimerie royale, 1785) to weighted voting games with voters of two kinds: a fixed (possibly empty) set of
‘major’ voters with fixed weights, and an ever-increasing number of ‘minor’ voters, whose total weight is also fixed, but
where each individual’s weight becomes negligible. As our main result, we obtain the limiting probability that the jury will
arrive at the correct decision as a function of the competence of the few major players. As in Condorcet’s result the quota
q = 1/2 is found to play a prominent role.

Background risk can influence the performance of insurance markets that must deal with adverse selection when applicants are risk vulnerable, since they are more averse to bearing the insurable risk as a result of their exposures to background risk. We show that background risk always results in a lower deductible for the incentive constrained contract, and that a broader range of markets attains the stable sequential equilibrium cross-subsidized pair of separating contracts. We conclude that background risk always improves the performance of markets for coverage against (insurable) foreground risks that must deal with adverse selection. We also find, however, that these improvements are never sufficient to offset the cost to insureds of bearing the background risk. 相似文献

This paper presents MAcMap–HS‐6, a database providing a consistent, ad valorem equivalent measure of tariff duties and tariff rate quotas for 163 countries and 208 partners, at the six‐digit level of the Harmonized System (5111 products), accounting for all preferential agreements. We describe the methodology used to compute and aggregate an ad valorem equivalent of applied protection. Emphasis is placed on minimizing the endogeneity bias in the aggregation procedure, while acknowledging structural differences in export specialization. The resulting quantitative assessment is illustrated by giving an overview of applied protection across the world in 2001, in terms of average as well as distribution. 相似文献
