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.   相似文献

This paper models a commercial real estate project where a wealth-constrained manager uses outside debt financing to purchase a project who's return depends on future economic conditions and the manager's investment in the project. It is shown that it is inefficient to finance the project with callable debt. This prediction is consistent with observed real estate financing practice. I also model the outcome of financial distress allowing for (1) debt forgiveness, (2) equity in exchange for debt forgiveness, and (3) foreclosure. The model motivates (1) why commercial real estate loans are often foreclosed, and (2) why lenders foreclose assets at fire-sale prices.  相似文献

Recreation Demand and Residential Location   总被引:2,自引:0,他引:2  
We use the properties of competitive location equilibrium to study the demand for recreation and the choice of primary residence location. Location-specific recreation and employment lead to pooling equilibria in which consumers reside according to their preference for recreation. In general, the stronger the taste for recreation, the greater the attraction of living close to the recreation site and the lower the demand for other goods, including housing. We explore the effects of trip frequency, trip length, and recreation cost on the spatial distribution of consumers. We also consider the effect of the wage rate on recreation and location demands.  相似文献

Based upon a review of the extant literature, it is proposed that the structure of an interorganizational relationship is composed of relationship type and the under‐researched construct of relationship magnitude. Specifically, it is hypothesized that relationship magnitude, a second order construct composed of trust, commitment, and dependence, affects relationship type, which affects the perception of value of the relationship. The results of a survey analyzed through structural equation modeling support these hypotheses.  相似文献

Practitioners and regulators are concerned that when auditors perceive management's attitude or character as indicative of low fraud risk, they are not sufficiently sensitive to high levels of incentive or opportunity risks in their overall fraud‐risk assessments. In this study, we examine whether a fraud‐triangle decomposition of fraud‐risk assessments (that is, separately assessing attitude, opportunity, and incentive risks prior to assessing overall fraud risk) increases auditors' sensitivity to opportunity and incentive cues when perceptions of management's attitude suggest low fraud risk. In an experiment with 52 practicing audit managers, we find that auditors who decompose fraud‐risk assessments are more sensitive to opportunity and incentive cues when making their overall assessments than auditors who simply make an overall fraud‐risk assessment. However, this increased sensitivity to opportunity and incentive cues appears to happen only when those cues suggest low fraud risk. When opportunity and incentive cues suggest high fraud risk, auditors are equally sensitive to those cues whether they use a decomposition or a holistic approach. We discuss and examine potential explanations for this finding.  相似文献

Spatial determinants of Japanese FDI in China   总被引:4,自引:0,他引:4  
Research on foreign direct investment in China has spawned an increasingly large literature. Whilst regional cleavages with respect to the distribution of foreign direct investment (FDI) are acknowledged, empirical research on the spatial determinants of FDI in China has been limited. Furthermore, research on the spatial determinants of home country FDI in China has thus far been neglected due to difficulties in accessing the appropriate data. The objective of this paper is to examine the spatial determinants of Japanese direct investment in China by using an econometric model. To that purpose, a dataset is created from the Toyo Keizai directory on the overseas activities of Japanese companies. The results show that tertiary education, inland waterways, as well as coastal location are positive and significant determinants of Japanese investment in China.  相似文献

Endogenous Group Formation   总被引:1,自引:0,他引:1  
While the rules governing the formation of groups engaging in collective action may have significant impact on group size and behavior of members, most experiments on public goods have been conducted with the subjects in exogenously fixed groups or of fixed sizes. We study endogenous formation of groups in a public‐goods provision game by allowing subjects to change groups under three sets of rules: free entry/exit, restricted entry with free exit, and free entry with restricted exit. We find that the rules governing entry and exit do have a significant impact on individual behavior and group‐level outcomes.  相似文献

The objective of this paper is to analyse how much the traditions of history research (HR) and futures research (FR) have in common and how they could assist each other. First, the role of time is analysed. Second, the path dependence theory, strategic decision-making, knowledge management and visionary management are discussed. Examples of the application of the latter in water and sanitation services and their long-term development are shown. Finally, some argumented views are presented on how the convergence between FR and HR could be improved.The key point of this research is the seeming discontinuity between presents, recent pasts and near futures. The traditions of HR probably make it more difficult to assess the effects of strategic decisions on the recent. If more convergence is wanted, the gap should be filled somehow. On the other hand, the core of FR research seems to concentrate more on strategic and visionary horizons while perhaps neglecting the operational horizon of the near future.  相似文献
