Policies to promote real-time metering (RTM) require more than showing benefits from more timely responses to variations in cost. They require positive externalities to imply that too few meters would be installed through private transactions. RTM presents no systematic externalities when utilities must serve peak period users, and may present negative externalities under some conditions. Positive externalities are likely when electricity is rationed through blackouts. RTM may or may not increase welfare when peak period wholesale markets are not competitive; a prohibition on RTM might be appropriate in such situations even if metering itself were costless. 相似文献

In the 1980s a number of large corporations restructured their diversified businesses through divestitures. It is hypothesized that restructuring activity focused on firms at intermediate levels of diversification (e.g., related-linked) which have a mixture of related and unrelated business units. Results confirm this hypothesis which explains that such mixed corporate strategies create organizational and control inefficiencies in managing both related and unrelated types of business units. Restructured firms were also found to move towards two types of different internal capital markets (related and unrelated). Most restructuring firms moved toward lower levels of diversification (e.g., related-constrained), although some moved toward higher levels of diversification (e.g., unrelated business). Also, this study finds restructuring firms that changed their corporate strategy by reducing diversified scope increased their R&D intensity. Firms that restructured and increased their diversified scope decreased R&D intensity. This result suggested a partial substitution between diversification and R&D activity. 相似文献

改革开放以来,我国四大地带产业结构的变动趋势大致相同,但东部各产业的劳动生产率和对经济增长的促进作用要明显优于中、西部和东北.目前四大地带产业排序已由二一三转变为二三一,接下来应促使第一产业的发展与农产品加工工业的发展相互适应,才能使区域的经济增长达到最佳效益.同时,鉴于各地带二、三产业对经济增长促进作用的大小同各产业从业人员的劳动生产率成正比,地区产业结构的调整还应注意劳动生产率的提高. 相似文献

We analyze welfare and distributional properties of a two-settlement system consisting of a spot market over a two-node network and a single energy forward contract. We formulate and analyze several models which simulate joint dispatch of energy and transmission resources coordinated by a system operator. The spot market is subject to network uncertainty, which we model as a random capacity derating of an important transmission line. Using a duopoly model, we show that even for small probabilities of congestion (derating), forward trading may be substantially reduced, and the market power mitigating effect of forward markets (as shown in Allaz and Vila 1993) may be nullified to a great extent. There is a spot transmission charge reflecting transportation costs from location of generation to a designated hub whose price is the underlying for the forward contract. This alleviates some of the incentive problems associated with the forward market in which spot-market trading is residual. We find that the reduction in forward trading is due to the segregation of the markets in the constrained state, and the absence of natural incentives for generators to commit to more aggressive behavior in the spot market (the strategic substitutes effect). In our analysis, we find that the standard assumption of no-arbitrage across forward and spot markets leads to very little contract coverage, even for the case with no congestion. We present an alternative view of the market where limited intertemporal arbitrage enables temporal price discrimination by competing duopolists. In this framework, we assume that all of the demand shows up in the forward market (or that the market is cleared against an accurate forecast of the demand), and the forward price is determined using a market clearing condition. 相似文献

逐步剥离:我国铁路重组合理组织边界的初步探讨 总被引:4,自引:0,他引:4
引入竞争、提高效率是我国铁路重组改革的重要目标指向,因此组织边界的确定以及与之相配套的竞争激励措施已成为重组模式选择的关键议题。本文以自然垄断和交易成本理论为指导,以竞争激励促进企业运行效率为依据,通过对世界各国多种重组模式的垄断与竞争格局进行比较分析,提出了用逐步剥离的方式逼近我国铁路重组合理组织边界的改革思路。 相似文献

This paper seeks to explain how policy actions undertaken at the outset of recent crises—particularly the issuance of extensive liquidity support and government guarantees—absorb off-budget fiscal resources and inappropriately constrain officials’ subsequent options for restructuring their country’s troubled financial and corporate sectors. Empirical evidence supports the commonsense view that the damage a crisis works on a country’s financial sector and on its real economy is lessened by taking market-mimicking actions that promptly estimate and allocate losses during the early stages of a crisis. The most important steps are to plan to call a timeout to separate hopelessly insolvent institutions from potentially viable ones and to provide haircuts, guarantees, and liquidity support in ways that protect taxpayers and avoid subsidizing insolvent institutions’ longshot gambles for resurrection. 相似文献

This paper examines takeover and divestiture activity at the industry level for the population of UK firms over the period 1986–2000. Consistent with US research, takeovers in the UK cluster both across industries and over time. The evidence for divestitures indicates clustering across industries only. The paper further investigates whether broad and specific industry shocks (e.g., growth, free cash flow, concentration, deregulation, foreign competition, technology, stock market performance) explain takeover and divestiture clustering at the industry level. The results suggest that broad shocks increase (decrease) the likelihood of takeovers (divestitures), although not significantly for takeovers. Specific industry shocks that increase the likelihood of takeover activity include low growth, the threat of foreign competition and high stock market performance. For divestitures, high industry concentration and deregulation increase activity. Little evidence is found for deregulation as a significant factor in explaining takeover activity. 相似文献
