Specifically, there is developed a computer simulation model to investigate the dynamic effects of budget documents on the research organization and the economy in which it is located. A flow chart to be incorporated in a computer program is presented. (Author)

Until now, that question has had little place in utility planning schemes. But the development of planning techniques based directly on customer preferences could help utilities identify more-effective market strategies, rate options, and products in an increasingly competitive environment.

The most commonly used economic measure of the perceived value of a good product is a consumer's willingness to pay for it. This determines the revenues to the seller. Profits can be rncreased in at least two ways; reduce the cost to provide service, or charge more while increasing perceived value to customers

In addition, a chance reliability constraint that can be incorporated into a mathematical programming model as a linear constraint is developed. Reliability is measured by loss-of-load probability. The constraint is based on a first-order approximation to the Gram-Charlier series representing the density function of available capacity minus load. Numerical results showing good agreement between the linear approximation and actual loss-of-load probability are presented.

Strategic reliability refers to the vulnerability of the power system to uncertain events such as fuel supply disruptions and unanticipated load growth that leads to adverse mis-matches in supply and demand for power. The model has been used to analyze key issues related to strategic resource planning for reliability, contingency planning, and vulnerability assessment for a major Power Pool in the East. INTRODWCTION Nature of Problem There is increased concern about the future adequacy of electricity supply in the U.S. This has lead to a concern about the vulnerability of a power system to prolonged energy/capacity shortages. This concern was triggered and successively reinforced by a number of events that threatened the ability of some power systems to meet consumer demand for electricity. Examples of such events include the 1973-74 oil embargo, the 1976-77 drought in the Pacific Northwest, the 1977-78 coal strike that was compounded by a severe winter, and the recent (1979) shortage of low sulfur residual oil experienced by East Coast utilities. In addition, the recent shutdown of the Three Mile Island (T,M Nos. 1 and 2) nuclear reactors raised concerns about the possibility of not only a generic nuclear shutdown but a nuclear moratorium as well.

ESMAP's mission is to promote the role of energy in poverty reduction and economic growth in an environmentally responsible manner. Its work applies to low-income, emerging, and transition economies and contributes to the achievement of internationally agreed development goals. ESMAP interventions are knowledge products including free technical assistance, specific studies, advisory services, pilot projects, knowledge generation and dissemination, trainings, workshops and seminars, conferences and round-tables, and publications. ESMAP work is focused on four key thematic programs: energy security, renewable energy, energy-poverty and market efficiency and governance. Governance and Operations ESMAP is governed by a Consultative Group (the ESMAP CG) composed of representatives of the World Bank, other donors, and development experts from regions which benefit from ESMAP's assistance. The ESMAP CG is chaired by a World Bank Vice-President, and advised by a Technical Advisory Group (TAG) of independent energy experts that reviews the Program's strategic agenda, its work plan, and its achievements. ESMAP relies on a cadre of engineers, energy planners, and economists from the World Bank, and from the energy and development community at large, to conduct its activities.

To date, however, this theory has found limited acceptance by portfolio managers. Though often not understood, or misunderstood, modern portfolio theory is rightfully criticized for being two-dimensional in its scope: it deals only with risk relative to return. Traditional analysts correctly recognize the portfolio selection problem as having more dimensions than this. This gap between the modern approach and the traditional approach that is popular with many portfolio analysts today opens the discussion that follows. The notion of a core security is then introduced. Indeed, core securities, determined by theMarkowitz model, are the missing links that help bridge the gap between the two approaches. Core securities were determined from the approved common stock list of the trust department of a major New England bank, and are explored in an empirical analysis later on in the article. u

Such sequential games are viewed as adaptive decision-making processes over time wherein each player updates his "stat? after every play. This revision may involve one's strategy or one's prior distribution on the competitor's strategies. It it shown that results from the theory of discrete time Markov processes can be applied to gain insight into the asymptotic behavior of the game. This is illustrated with a duopoly game in economics. sequential game ergodic theory oligopoly games quasi-compact operators sequential decision making * This paper is based on the author's Ph.D. dissertation submitted to Yale University.

This includes the classical Cournot reaction function. Our stochastic reaction functions are the rules by which firms revise their prior distributions on their competitors' sets of actions. The asymptotic stability of a class of stochastic reaction functions is examined in this paper. It is shown that there exists a class of reaction functions that are either asymptotically stable in the Cournot-Nash sense or asymptotically Pareto optimal. Our analysis does not rely on differentiability and other assumptions traditionally imposed in the literature.

General properties of discrete-time Markov processes are applied to specific games such as iterated matrix games, including Prisoners' Dilemma, and to a new model for the Asch experiments on conflict and conformity.

Such an explicit cost-benefit analysis provides the basis for answering the economic question: How much reliability is adequate from the customer's perspective? Several issues and questions have been rasised in the context of such an approach. This paper addresses and clarifies the more commonly rasised issues about value of service reliability, and related notion of customer interruption costs. 2 COST OF SUPPLY INTERRUPTIONS This section briefly identifies and defines the key concepts of relevance and their interrelationships-such as "outage cost",

The regulatory agency's decision is difficult, to say the least. The social costs of both over-and under-building can be high. It is therefore imperative that the tradeoff between the costs of over-and under-capacity be evaluated, This study develops a decision analysis framework to study the need for additional electrical generating capacity in the presence of divergent load growth forecasts. A method for determining the costs of over-and under-building capacity is developed and applied to the Pacific Northwest region of the USA. Our results support the conclusion that in the Pacific Northwest the social costs of over-building are lower than the costs of under-building.
