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

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

We present a theory of capital structure based on the power of shareholders, bondholders and managers to control the incentive conflicts in large corporations. The manager–owner conflict produces a trade-off between inefficiency in the low state and rents in the high state, and the shareholder–bondholder conflict produces under-investment as in Myers [Journal of Financial Economics 19 (1997) 147]. Since managers and bondholders both prefer more efficient actions in the low state, the two conflicts are interdependent. With risk-less levels of debt, there are no shareholder–bondholder agency costs, but managerial control over the incentive-setting process produces excessive rents. With risky debt, shareholders focus more on returns in the high state so that shareholder–bondholder agency costs increase but managerial rents decrease. Efficient levels of debt holder protection facilitate a reduction in manager–owner agency costs that outweighs shareholder–bondholder agency costs, and are decreasing in firm performance. The results are consistent with the separate empirical results relating control to both compensation and leverage, and suggest how future studies can be integrated. 相似文献

We consider the design of ambient taxes forrisk-neutral and risk-averse polluters whenpolluters and the regulatory agency haveasymmetric information about environmentalrelationships and probabilities associatedwith random events. Unlike prior work, we showthat under these conditions, optimal ambienttaxes must be firm-specific, and accompaniedby additional incentives to influencepolluters' choices of abatement techniques. 相似文献

This paper considers the likely impact of e–commerce and the Internet on the Australian economy. It surveys literature on the extent and development of e–commerce in Australia and its impact on the shape of the Australian economy. Evidence for the 'renewal' of the Australian economy is presented and examined, especially the question of whether Australia has enjoyed increases in productivity as a result of the production and/or use of new information and communications technology. Australia is seen as broadly well placed to benefit from the Internet and e–commerce. Traditionally isolated from the world's main economic centres and reliant on commodities in international trade, the advent of the Internet is ideal for a country in transition to a service–orientated, knowledge–based economy. As the composition of Australia's exports becomes more service–orientated and knowledge–intensive, traditional trading links with Europe and North America may strengthen relative to those with Asia. 相似文献
