a simple framework for international monetary policy analysis abstract we study the international monetary policy design problem within an optimizing two country sticky price model where each country faces a short run tradeoff between output and inflation the model is sufficiently tractable to solve analytically we find that in the nash equilibrium the policy problem for each central bank is isomorphic to the one it would face if it were a closed economy gains from cooperation arise however that stem from the impact of foreign economic activity on the domestic marginal cost of production while under nash central banks need only adjust the interest rate in response to domestic inflation under cooperation they should respond to foreign inflation as well in either scenario flexible exchange rates are desirable

transmission system management and pricing new paradigms and international comparisons the transmission system once the necessary but nearly invisible component of the electric power system is now the focus of physical electrical and financial attention of the utility and more significantly their potential suppliers customers this paper has three primary objectives the first is to present a discussion of a new paradigm for the electric power industry the second is to review transmission pricing options specifically those utilizing either long run lrmc or short run srmc marginal cost based approaches the third is to provide a review of innovative approaches to transmission asset management and finance as seen from international experience

dynamics of a sticky price small open economy facing technology shocks why be open this article presents a small open economy model which is a part of the world that consists of a continuum of infinitesimal open economies new keynesian investment saving line is and phillips curves are derived for the small open economy and the rest of the world for five different policies i e domestic inflation targeting consumer price index cpi inflation targeting exchange rate peg domestic inflation taylor rule and cpi inflation taylor rule the effects of domestic and world technology shocks are analysed the degree of openness is discussed and the effect of openness is addressed by comparing the impulse responses of a small open economy and closed economy that face productivity shocks

coalition formation in transmission expansion planning the study of a decentralized coalition formation scheme in a specific power systems transmission expansion scenario is the purpose of this paper the authors define first who are the agents in the expansion game and provide a decentralized coalition scheme based on bilateral shapley values finally they allocate the total costs of expansion amongst the agents based on the coalition history and they compare their method with a centralized scheme

monetary policy and exchange rate volatility in a small open economy we lay out a small open economy version of the calvo sticky price model and show how the equilibrium dynamics can be reduced to a simple representation in domestic inflation and the output gap we use the resulting framework to analyse the macroeconomic implications of three alternative rulebased policy regimes for the small open economy domestic inflation and cpi based taylor rules and an exchange rate peg we show that a key difference among these regimes lies in the relative amount of exchange rate volatility that they entail we also discuss a special case for which domestic inflation targeting constitutes the optimal policy and where a simple second order approximation to the utility of the representative consumer can be derived and used to evaluate the welfare losses associated with the suboptimal rules

allocation of unit start up costs using cooperative game theory this paper discusses a three part generation offer strategy that enables generators to put in unbundled variable operating costs and fixed start up no load costs we then propose methods based on cost sharing axioms to allocate fixed start up no load costs among electricity consumers load retailers that take into account equity and rationality considerations we focus on the single period cost allocation first we apply three well known game theoretic axioms the core the nucleolus and the shapley value we discuss the relative merits and demerits of each criterion and also explore certain theoretical conditions for the existence of the core and the shapley value lying inside the core finally the multiperiod start up cost allocation problem is studied allocations based on individual periods vis a spl grave vis composite allocation for all periods are compared and contrasted numerical examples are used to illustrate all theoretical concepts

using game theory to analyze electric transmission pricing policies in the united states abstract us public policy towards the private electric power industry is moving away from restrictive regulation and towards promotion of competition alternative policies concerning access to and pricing of transmission are now being discussed similar issues may arise in europe as trade barriers fall our purpose is to show how game theory can help illuminate that debate and identify desirable policies game theory models are used to estimate the possible effects of various policies upon productive efficiency and the distribution of gains among sellers transmitters and buyers of power static cooperative models are used to calculate the possible outcomes of short run transmission games long run games in which the amount of transmission capacity is a decisition variable are modeled as dynamic noncooperative stackelberg games one conclusion is that under some conditions price regulation and mandatory access could hurt power buyers by removing incentives for building transmission capacity another conclusion is that under a system of voluntary access and price regulation it may be better to allow wheeling prices to exceed the marginal cost of transport rather than to risk losing the benefits of cooperation

the anatomy of job loss and job creation some speculations on the role of the producer service sector wood p a 1986 the anatomy of job loss and job creation some speculations on the role of the producer service sector reg studies 20 37 46 studies of recent employment trends in the united kingdom have highlighted job losses arising from restructuring by large manufacturing firms this paper examines the relationships between this and other shifts in labour demand emphasizing the complexity of change and especially the growing importance of producer services jobs are likely to continue to be transferred between increasingly interrelated manufacturing and service activities and the corporate and competitive segments of the economy the implications of these trends for sub regional economic change are examined and areas are identified which may be particularly favoured by producer service employment growth these include london industrial towns in the south east and freestanding cities and non industrial towns in the north

econometric policy evaluation and inverse control the traditional approach to monetary policy evaluation entails a first step in which structural parameters are estimated and a second in which the performance of alternative policy rules is studied this paper combines the two steps of the traditional approach into one by estimating a structural model subject to the restriction that the central bank chooses the policy rule that minimizes expected loss the structure is a forward looking new keynesian model in which equilibrium values of output and inflation depend on expectations of future values of those variables analysis of u s data between 1965 and 2001 support the hypotheses that the sample contains two policy regimes that the fed placed far greater weight on stabilizing inflation after 1980 and that improvements in policy were available in both regimes the unified approach also sharpens estimates of structural parameters

the changing geography of producer services employment in britain gillespie a e and green a e 1987 the changing geography of producer services employment in britain reg studies 21 397 411 this paper examines the changing geography of producer services employment in britain between 1971 and 1981 using data from the census of employment the study begins with a review of alternative views on the service sector and its relationship to economic growth and the place of producer services within the division of labour is described it is shown that there is a pronounced urban and regional differentiation in producer services employment factors operating to increase the concentration of such employment are indentified as are counteracting tendencies favouring deconcentration individual producer services industries are shown to display different locational logic and varying trends of concentration and deconcentration during 1971 81 overall the maintenance of the spatial concentration of producer services employment in southern britain coupled with relative decon

old industrial areas a theoretical approach the paper tries to put forward a hypothesis for the changing fortunes of old industrial areas a regionalized version of the product cycle hypothesis is used as a link for various aspects of the lost dynamics of this type of region as interpreted by different models of regional growth it offers an endogenous explanation for the change from prosperous to old old industrial areas are at the end of a regional life cycle a stage of development that is marked by inflexibilities of the regions supply and a lack of innovative ability some implications of this approach for policy implementation are considered

business services the regions and regional policy marshall j n 1985 business services the regions and regional policy reg studies 19 353 363 the decline of employment in manufacturing industry in the uk has encouraged a more favourable treatment of services in regional policy an analysis of the employment prospects for private services suggests further modest growth and justifies the inclusion of such services in a policy package however service employment creation in less prosperous regions has been relatively limited an analysis of business service industries attempts to account for the changing location of service activity and derives implications for regional policies in an increasingly competitive market for services organizational restructuring assisted in some services by computer based technology has encouraged the decentralization of employment from london predominantly to the greater south east regional policy is unlikely to operate in such a favourable economic context in the immediate future rationalization investment is

a theory of urban decline economy demography and political elites during the past decades large cities in advanced industrialised countries have experienced different demographic and economic trajectories some are continuing to grow in population and jobs many have experienced decline to account for the process of decline and its consequences a general model of urban decline is proposed it specifies the relationship between employment population political elites and urban fiscal revenues constructs and propositions are drawn from economic and ecological theorems empirical evidence is based on literature predominantly from germany and the us

the potential bias in producer service employment estimates the case of the canadian space economy footloose information technology producer services are increasingly viewed as the new engines of regional growth and employment creation the claim is often that appropriate government policy can engineer comparative advantage in that direction by means of judicious subsidisation the evaluation of such claims relies on accurate statistical data we argue that attempts to distinguish in survey data or official statistics the subset of services commonly but unofficially known as producer services from consumer and government services may result in a potential bias with implications for public policy an input output model is developed for estimating this bias by decomposing service industry data into its producer and consumer services content this method can give a truer estimate of the actual employment in producer services at various spatial levels we find a systematic bias in official data and a non systematic bias in survey data the model is applicable to countries and regions for which input ou

optimal multi area wheeling an important consideration in wheeling is where a transaction involves several parties that is multi area wheeling power from seller to buyer flows through several intermediate utilities each utility represents an individual control area engaged in part of a more complex wheeling transaction individual wheeling rates then have to be computed for each area the question of how much energy should be transported through each path and what wheeling price should be paid is then an issue of importance this is formulated as a nonlinear optimisation program with linear constraints and solved by a gradient projection method the availability of facts capability to implement the optimal wheeling strategy once determined is assumed in this paper

producer services trade and the social division of labour goe w r 1990 producer services trade and the social division of labour reg studies 24 327 342 several hypotheses have been advanced to explain the growth in employment and output of producer services industries in us metropolitan and regional economies one hypothesis contends that this growth is attributable to the increasing externalization of service activities by corporate managerial offices to independent producer services firms this has contributed to the growth of corporate complex agglomerations in urban regions manufacturing industries have traditionally been viewed as being the motivating force underlying this growth a second hypothesis contends that the growth of producer services industries is attributable to their evolution into basic industries and the growth of export trade this paper examines the validity of these hypotheses using data collected from a survey of business establishments in producer services industries located in the four metropolitan areas of the northeast regi

transmission analysis by nash game method this paper describes an open access transmission method for maximizing profits in a power system the proposed method is based on the nash bargaining game for power flow analysis in which each transaction and its optimal price are determined to optimize the interests of individual parties transmission losses are considered by the proposed method and test cases and results are discussed to present the merits of the proposed method

framework for energy brokerage system with reserve margin and transmission losses the power industry in the united states is presently participating in a changing business environment while planning to meet future peak demand is still a concern the efficient utilization of existing generation and transmission resources is fast becoming of primary interest this interest suggests to move from cost based market operations to price based market operations in such a business environment a need for a mechanism to determine the pricing of various ancillary services is desired as the ancillary services go together with electrical power transfer the proposed approach develops a novel method of pricing mechanism for reserve margins and transmission losses as a part of the overall transaction in an energy brokerage system the brokerage model described in this paper is based on formulations using linear programming

strategic bidding in an energy brokerage this focus of this paper is to present a framework in which strategies may developed for the individual participants in an energy brokerage such a framework is expected to be important with the increasing interest in electricity market structures such as the energy brokerage that deregulation has produced to illustrate the process of strategic bidding a simple suboptimal bidding strategy is presented with the aid of a numerical example the bidding strategy must be suboptimal because of the amount of unknown information about the other bidders further tuning of this strategy will be required before application to realistic scenarios
