The creation of an energy metasystem that combines electrical, heat, cooling, and gas supply systems on an intellectual framework is a manifestation of a new energy paradigm. Integrated intelligent power supply systems combine complexity, intelligence, efficiency, reliability, controllability, flexibility of energy conversion, transmission, storage technologies and assume an active consumer. 相似文献

We examine how different methods of reparations payments to African‐Americans affect both the black and nonblack populations of the United States using the framework of the transfer‐problem from international trade theory as a theoretical foundation. We find that reparations payments that provide incentives for blacks to use the payment toward purchases of goods and services produced by nonblacks might expand the income gap. Also a reparations payment in the absence of productive capacity owned by blacks is found to have no final positive impact on black income. These results indicate that a reparations payment strategy must be carefully and cautiously conceived in order to achieve the desired effects. 相似文献

This paper concludes that a market for state-contingent claims (UK horserace betting) displays evidence of pervasive but heterogeneous forms of inefficiency, in significant contrast to earlier investigations. Using hitherto unavailable data, comparison of notional returns implicit in parallel sets of bookmaker and parimutuel odds identifies inefficiency in terms of zones of distinct but contrasting forms of cross-;market returns differential. The inefficiency is rationalized in terms of both buyer and supplier behaviour; its durability is explained in terms of limited arbitrage opportunities. 相似文献

This article emphasizes the importance of behavioral considerations at individual, organizational, and environmental levels of analysis when researching and evaluating the design, implementation, and use of group decision support systems (GDSS) within complex organizations. Discussion is based on interview and archival data collected on an executive level GDSS used within a corporate setting. Issues that are considered generalizable to organizational computing, coordination, and collaboration technologies concern (a) viewing organization participants as strategic, intuitive information processors, (b) understanding the importance of organizational power, politics, and situational constraints on decision making, and (c) appreciating the symbolic value of advanced information technologies to an organization's external environment. 相似文献

To assist pest management planning, the Canadian Forest Service developed the Spruce Budworm Decision Support System (SBW DSS), which quantifies the timber supply impacts of protecting stands against spruce budworm (Choristoneura fumiferana Clem.) defoliation. We incorporated protection costs and timber product values in this system to evaluate economic aspects of spruce budworm control. The analysis allows pest managers to evaluate the degree to which the traditional volume protection priority objective corresponds to three economic criteria, namely the volume protected per dollar protection program cost, the benefit–cost ratio of the protection program, and the net present value of the protection program. Twelve alternative spruce budworm protection strategies were analyzed on Crown License 1 in New Brunswick and Prince Albert Forest Management Area (PAFMA) in Saskatchewan, based on a number of protection program extents and intensities. For both landbases under base-case market conditions, the largest, most intensive protection scenario provided the highest amount of volume saved and net present value (at 3.94 Mm3 and $39.98 M for PAFMA, and 4.04 Mm3 and $41.49 M for License 1, respectively) while smaller, less-intensive programs provided the highest benefit–cost ratios and volume protected per present value dollar of protection cost (at 8.22 and 0.52 m3/$ for PAFMA, and 10.26 and 0.65 m3/$ for License 1, respectively). Sensitivity analysis on product values and protection costs revealed that smaller, less-intensive programs could also produce the highest net present values when costs are higher and/or product values lower. These results highlight the conditions under which pest managers should consider deviating from their traditional strategy of maximizing volume saved to one that maximizes the economic returns of protection. 相似文献

The main goal of this paper is to examine the relationship between the three most important characteristics of the board of directors with firm performance. More specifically, we investigate whether the independence of the board, the leadership structure and the board size, are exogenous determinants to the firm's performance, using a simultaneous equations framework. Our database is composed of firms quoted in the ASE, starting from 146 observations in 2000 and ending with 232 firms in 2006. The findings suggest that the board independence and the leadership structure do not affect the firm performance. On the other hand, an inverse relationship between board size and firm performance is observed. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

This paper explores ethical burdens facing the economics profession which are associated with epistemic features of economic practice. Economists exert power over those they purport to serve by virtue of epistemic asymmetry between themselves and others, i.e., the intellectual monopoly they enjoy over a vitally important body of knowledge. But they also face the problem of epistemic insufficiency, which implies that they may do substantial harm as they try to do good. The paper explores the ethical entailments of the epistemic features of economics, and argues that managing the ethical challenges requires a new field of inquiry, the field of professional economic ethics, and not just a code of conduct. 相似文献

A “Timeless” charge to consumer economics and family economics is identified. In light of the charge, the area is examined with particular emphasis on scholarly activity. It is suggested that scholarship in the area is diffuse and often addresses parts of issues. This creates concerns as to whether the historical charge is being met. 相似文献

The European Central Bank (ECB) recently announced its willingness to do whatever is needed to save the euro. This has raised the question whether such a role of the ECB must lead to higher rates of infl ation. Under current recessive macroeconomic conditions in the eurozone, the ECB’s expansionary monetary policy will not lead to higher infl ation. On the contrary, there is a serious danger of defl ation. Higher infl ation would likely occur only if a permanent stabilisation function were assigned to the ECB. Yet historical examples show that mistakes can be made. During the stagnation in Japan, US economists heavily criticised the Bank of Japan’s timid monetary policy response. But in some sense, current Fed policy seems to be a direct copy of that strategy, caused by uncertainty about the proper communication channel. An infl ation tax could help to bring down the mounting public debt in the wake of the fi nancial crisis, but higher wealth taxes have more transparent distributional effects. 相似文献
