This paper examines the impact of regulated piped gas price changes on connection decisions and households’ welfare. The analysis explicitly considers bottled gas as a substitute for piped gas and therefore uses a simple utility maximization model that yields both a gas-type choice model and a demand specification whose parameterization allows examining households’ responses to regulated price changes. The results show that relative gas prices and household features explain households’ piped gas usage. They also provide insights on the distribution of welfare changes. The findings illustrate the impact of tariff rebalancing and unregulated substitutes on further access to regulated network services. 相似文献

This paper examines productivity patterns in price cap regulated utilities around price reviews. We specify a variable cost function that we estimate using alternative specifications of technical change. Results show that the pattern of pure technical change differs within and between regulatory cycles. They also provide evidence that exogenous investment reduces the ratchet-problem, that strategic cost cutting behavior is reduced when regulatory cycles are short and that, absent these two features, industry productivity is consistent with strategic cost cutting behavior. 相似文献

Development of renewable energy resources, such as wind farms and hydro-electric schemes, are being promoted as a new method of expanding and diversifying employment in rural areas. However, such energy projects are associated with a range of environmental impacts which might be detrimental to other economic activities, such as those based on nature tourism. The authors use a Choice Experiment to quantify peoples' preferences over environmental and employment impacts that may result from the deployment of renewable energy projects in rural areas of Scotland, focussing in particular on any differences between the preferences of urban and rural dwellers, and on heterogeneity within these groups. Rural and urban households are shown to have different welfare gains which are dependent on the type of renewable energy technology and on the scale of project under consideration. 相似文献

We view a debate as a mechanism by which an uninformed decision maker (the listener) extracts information from two informed debaters, who hold contradicting positions regarding the right decision. During the debate, the debaters raise arguments and, based on these arguments, the listener reaches a conclusion. Using a simple example, we investigate the mechanism design problem of constructing rules of debate that maximize the probability that the listener reaches the right conclusion, subject to constraints on the form and length of the debate. It is shown that optimal debate rules have the property that the conclusion drawn by the listener is not necessarily the same as the conclusion he would have drawn, had he interpreted the information, revealed to him or her during the debate, literally. The optimal design of debate rules requires that the information elicited from a counterargument depends on the argument it counterargues. We also link our discussion with the pragmatics literature.

We develop a general framework that extends choice models by including an explicit representation of the process and context of decision making. Process refers to the steps involved in decision making. Context refers to factors affecting the process, focusing in this paper on social networks. The extended choice framework includes more behavioral richness through the explicit representation of the planning process preceding an action and its dynamics and the effects of context (family, friends, and market) on the process leading to a choice, as well as the inclusion of new types of subjective data in choice models. We discuss the key issues involved in applying the extended framework, focusing on richer data requirements, theories, and models, and present three partial demonstrations of the proposed framework. Future research challenges include the development of more comprehensive empirical tests of the extended modeling framework. 相似文献

We estimate parameters from data on discrete dynamic games, using entry/exit games to illustrate. Semiparametric first‐stage estimates of entry and continuation values are computed from sample averages of the realized continuation values of entrants and incumbents. Under certain assumptions, these values are easy‐to‐compute analytic functions of the parameters of interest. The entry and continuation values are used to determine the model's predictions for entry and exit conditional on the parameter vector, and the estimates compare these predictions with the data on entry and exit rates. Small‐sample properties are discussed and lead to the simplest of estimators. 相似文献

This paper provides an overview of the evolution of the industrial economies in the 1960s, with particular attention to the factors which gave rise to the economic crisis of recent years. The effects of this international economic instability on the developing economies is then considered, especially the weakening of their balance-of-payments position which has increased their dependence on external finance. The author indicates that the developing countries' growing reliance on credits from private international banks gives cause for concern and he proceeds to make some suggestions for other mechanisms of development financing. 相似文献

The difficult circumstances being faced by the world economy and its uncertain prospects for the 1980s make it necessary to take a new look at the present financial mechanisms and international institutions for monetary cooperation, with a view to adapting them to current needs and to developments in the near future. The industrial countries will have more modest rates of growth than in earlier decades, and this will have significant consequences for the developing countries: (a) stagnation of official development aid flows; (b) possible intensification of protectionist trends; (c) slow growth of producers of raw materials whose export markets will be seriously limited; (d) gradual shift of world economic and political activity toward oil-producing developing countries and, to a lesser extent, toward the exporters of manufacturers; (e) industrial countries and raw materials producers will become increasingly interdependent; (f) oil-producing and other higher income developing countries will increase their participation in regional economic cooperation and official development aid efforts. Some of the more specific problems which require attention from the international community are inflation and recession; structural disequilibria, recycling and external debt; adjustment process; creation of liquidity and transfer of resources; and participation of the developing countries in the monetary system. 相似文献

How effective is agricultural extension? Is it worth the vastsums governments spend to provide it, mostly as a free service,to farmers worldwide? Relatively few studies exist that measureand compare the benefits of extension activities against theircosts. In the absence of such data, this pilot activity concentratedinstead on demand. Would demand for extension services be highif they were no longer free? The existence of solid demand wouldpresuppose some benefits from the service. Further, might chargingfor the service actually improve its quality and sustainability? The pilot program in Nicaragua described here set out to testwhether a truly demanddriven extension system aimed atfarmers with small-and medium-size holdings could be developed.The principal mechanism was a contribution by the farmer paidas a bonus to the extensionist: the aim was to introduce incentivesfor providers to improve the service through rewards linkedto the quality of their work and to establish direct accountabilityof extensionist to client. The outcomes showed that the cofinancingconcept can be successful. The article describes the design,implementation, and results in the expectation that the lessonslearned may be of interest elsewhere. 相似文献

This paper discusses six major changes and challenges that have emerged since World War II that will shape the global economy for the indefinite future. These are the changing economic role of women, the emergence of the global economic and financial system, the re-emergence of state-supported enterprises, the impact of the Internet, the global diffusion of opportunity and innovation, and globalization as an opportunity and a threat. How these challenges are addressed will have important consequences for business and for public policy. In addition to the prepared remarks, this paper also has a summary of the question-and-answer session that followed Dr. Hormats’ address. 相似文献
