dividend taxes corporate investment and q abstract taxes on corporate distributions have traditionally been regarded as a double tax on corporate income this view implies that while the total effective tax rate on corporate source income affects real economic decisions the distribution of this tax burden between the shareholders and the corporation is irrelevant recent research has suggested an alternative to this traditional view one explanation of why firms in the united states pay dividends in spite of the heavy tax liabilities associated with this form of distribution is that the stock market capitalizes the tax payments associated with corporate distributions this capitalization leaves investors indifferent at the margin between a corporation s decision to pay out dividends or to retain earnings this alternative view holds that while changes in the dividend tax rate will affect shareholder wealth they will have no impact on corporate investment decisions this paper develops econometric tests which distinguish between these two views of dividend taxation by extending tobin s q theory of investment to incorporate taxes at both the corporate and personal levels the implications of each view for corporate investment decisions can be derived the competing views may be tested by comparing the performance of investment equations estimated under each theory s predictions british time series data are particularly appropriate for testing hypotheses about dividend taxes because of the substantial postwar variation in effective tax rates on corporate distributions the econometric results suggest that dividend taxes have important effects on investment decisions

theoretical approaches to monetary disinflation abstract during the 1980s many countries adopted tight monetary policies to reduce high inflation rates which were the legacy of the 1970s as inflation threatens to rise at the beginning of this decade this paper provides a survey of the 1980s literature which sought to provide theoretical understandings of how monetary disinflation is achieved four models are presented monetarist neo keynesian new classical and post keynesian each model s explanation of the recession which accompanies the monetary disinflation is outlined as well as possible policy measures to reduce the extent of the recession and to hasten the return to full employment

consistent solutions in atomless economies we consider the problem of allocating a bundle of commodities among a group of agents who are collectively entitled to them we prove for an atomless economy with possibly satiated preferences any solution that is efficient equitable and consistent must select allocations that are supported by equal budget walrasian equilibria with slack we consider the problem of allocating a bundle of commodities among a group of agents who are collectively entitled to them we search for systematic methods or solutions of resolving this problem for a solution to be considered desirable we propose that it should satisfy several requirements first it should be efficient second it should be equitable a variety of distributional require ments have been proposed in the literature the requirement we will impose here is that it select allocations at which no agent would prefer the equal division of the social endowment to his own consumption in addition to these two basic efficiency and equity conditions we require that the solution be consistent the recommendations it makes for any economy are never contra dicted by the recommendations it makes for any reduced economy obtained by allowing some subgroup of agents to leave the scene with their allotted consumptions the requirement of consistency is very natural here is a motivation for it offered by thomson 1988 consider all the resources available on the planet earth one would like not only that they be distributed fairly when the planet is considered as a whole but also that whatever resources end up in each continent country city be fairly distributed among the members of that subpopulation when considered in isolation in this paper we study economies with a large number of agents modelled as a complete atomless measure space our main result is a characterization of the solutions that satisfy all three requirements of efficiency equity and con sistency it follows from our result that under standard assumptions on preferences any such solution must select allocations that are supported by equal income walrasian equilibria however our characterization holds for more general economies since it applies to economies in which preferences are possibly satiated mas colell 1988 extended traditional general equilibrium theory to the class of such economies by introducing the notion of walrasian

oil price shocks and their short and long term effects on the chinese economy a considerable body of economic literature shows the adverse economic impacts of oil price shocks for the developed economies however there has been a lack of empirical study of this kind on china and other developing countries this paper attempts to fill this gap by answering how and to what extent oil price shocks impact china s economy emphasizing on the price transmission mechanisms to that end we develop a structural vector auto regressive model our results show that an oil price increase negatively affects output and investment but positively affects inflation rate and interest rate however with the differentiated price control policies for materials and intermediates on the one hand and final products on the other hand in china the impact on real economy represented by real output and real investment lasts much longer than that to price monetary variables our decomposition results also show that the short term impact namely output decrease induced by the cut of capacity utilization rate is greater in the first one to two years but the portion of the long term impact defined as the impact realized through an investment change increases steadily and exceeds that of short term impact at the end of the second year afterwards the long term impact dominates and maintains for quite some time

a three level static milp model for generation and transmission expansion planning we present a three level equilibrium model for the expansion of an electric network the lower level model represents the equilibrium of a pool based market the intermediate level represents the nash equilibrium in generation capacity expansion taking into account the outcomes on the spot market and the upper level model represents the anticipation of transmission expansion planning to the investment in generation capacity and the pool based market equilibrium the demand has been considered as exogenous and locational marginal prices are obtained as endogenous variables of the model the three level model is formulated as a mixed integer linear programming milp problem the model is applied to a realistic power system in chile to illustrate the methodology and proper conclusions are reached

energy and resource allocation a dynamic model of the dutch disease it is well known that a domestic resource discovery gives rise to wealth effects that cause a squeeze of the tradeable good sector of an open economy the decline of the manufacturing sector following an energy discovery has been termed the dutch disease and has been investigated in many recent studies our model extends the principally static analyses to date by allowing for 1 short run capital specificity and long run capital mobility 2 international capital flows and 3 far sighted intertemporal optimizing behaviour by households and firms the model is solved by numerical simulation

unemployment equilibria and input prices theory and evidence from the united states the paper develops an efficiency wage model where input prices affect the equlibrium rate of unemployment we show that a simple framework based on only two prices the real price of oil and the real rate of interest is able to explain the main post war movements in the rate of u s joblessnss the equations do well in forecasting unemployment many out of sample and provide evidence that the oil price spike associated with iraq s invasion of kuweit appears to be a component of the mystery recession which followed

structural change and the macroeconomic effects of oil shocks empirical evidence from the united states and japan abstract this paper investigates whether the usa and japan have become better insulated from oil price disturbances due to more favorable structural conditions new production technologies allowing greater energy substitution the development of energy commodity markets reduced energy intensity of production more market oriented energy policies and so on we decompose the influences of oil shocks on real gnp growth and inflation movements in the context of a simultaneous equation model where identification is partly achieved by restricting the long run dynamics we find that oil shocks accounted for a greatly reduced fraction of real gnp growth and inflation variance in both countries primarily because of superior insulation characteristics rather than reduced importance of oil disturbances our estimates suggest that a similar percentage oil price hike would have exerted about one quarter the contractionary effect on real gnp and upward push in inflation in the 1980s compared with the previous two decades jel e31 e32 f30

grid integration of intermittent renewable energy sources using price responsive plug in electric vehicles abstract plug in electric vehicles pevs are expected to balance the fluctuation of renewable energy sources res to investigate the contribution of pevs the availability of mobile battery storage and the control mechanism for load management are crucial this study therefore combined the following a stochastic model to determine mobility behavior an optimization model to minimize vehicle charging costs and an agent based electricity market equilibrium model to estimate variable electricity prices the variable electricity prices are calculated based on marginal generation costs hence because of the merit order effect the electricity prices provide incentives to consume electricity when the supply of renewable generation is high depending on the price signals and mobility behavior pevs calculate a cost minimizing charging schedule and therefore balance the fluctuation of res the analysis shows that it is possible to limit the peak load using the applied control mechanism the contribution of pevs to improving the integration of intermittent renewable power generation into the grid depends on the characteristic of the res generation profile for the german 2030 scenario used here the negative residual load was reduced by 15 22 and the additional consumption of negative residual load was between 34 and 52

do oil price shocks matter evidence for some european countries this paper analyzes the oil price macroeconomy relationship by means of analyzing the impact of oil prices on inflation and industrial production indexes for many european countries using quarterly data for the period 1960 1999 first we test for cointegration allowing for structural breaks among the variables second and in order to account for the possible non linear relationships we use different transformation of oil price data the main results suggest that oil prices have permanent effects on inflation and short run but asymmetric effects on production growth rates furthermore significant differences are found among the responses of the countries to these shocks

economic growth inflation and oil shocks are the 1970s coming back this article analyses the relationship between oil price shocks and the macroeconomic evolution of the group of seven g7 countries using the qu and perron 2007 methodology we endogenously identify three breaks in the nonlinear relationship across our 1970 to 2008 sample we compute long term multipliers and find that the response of output and inflation to oil price shocks is greatest in the 1970s and progressively disappears until the late 1990s in contrast to the previous literature we observe that both effects reappear in the 2000s especially on inflation nevertheless the transmission of oil price shocks to the economy is weaker than in the 1970s which means that oil price shocks have lost some of their explanatory power precisely identifying these effects is crucial for the design of adequate economic measures to control or smoothen them

real time pricing to assist in load frequency control we study the use of real time prices to assist in the control of frequency and tie line deviations in electric power systems the role of such prices if any would yield the practical limit to the trend in electric power systems of varying prices on ever faster time scales the application of prices in electric power systems to increase the efficient use of resources is an established technique the pricing schemes can be classified by time scales energy adjustment charges vary seasonally or monthly while time of day rates vary two or three times per day the power brokering system of 18 florida utilities operates on an hourly time scale in a spot price market of buyers and sellers of electric power prices adapt to system operation conditions such as changes in system lambda the effect of generation shortages and the effect of line overloads the fastest spot price that has been implemented to date is 30 minutes most implementations involve 1 hour time steps which may be prespecified 24 hours in advance on a five minute time scale is system lambda a shadow price used internally by electric utilities for economic dispatch a key assumption of spot pricing and economic dispatch is that the power system is in quasi steady state i e power system dynamics involving frequency voltage etc are ignored and only kirchoff s laws for network are considered the paper explores pricing at time scales where the quasi steady state assumption is no longer valid

a comparison of the effects of exogenous oil supply shocks on output and inflation in the g7 countries a comparison of the effects of exogenous shocks to global crude oil production on seven major industrialized economies suggests a fair degree of similarity in the real growth responses an exogenous oil supply disruption typically causes a temporary reduction in real gdp growth that is concentrated in the second year after the shock inflation responses are more varied the median cpi inflation response peaks after three to four quarters exogenous oil supply disruptions need not generate sustained inflation or stagflation typical responses include a fall in the real wage higher short term interest rates and a depreciating currency with respect to the dollar despite many qualitative similarities there is strong statistical evidence that the responses to exogenous oil supply disruptions differ across g7 countries for suitable subsets of countries homogeneity cannot be ruled out a counterfactual historical exercise suggests that the evolution of cpi inflation in the g7 countries would have been similar overall to the actual path even in the absence of exogenous shocks to oil production consistent with a monetary explanation of the inflation of the 1970s there is no evidence that the 1973 1974 and 2002 2003 oil supply shocks had a substantial impact on real growth in any g7 country whereas the 1978 1979 1980 and 1990 1991 shocks contributed to lower growth in at least some g7 countries jel e31 e32 q43

the social cost of imported oil abstract this article analyses the social cost of imported oil from both a conceptual and empirical perspective a conceptual framework of the oil import premium the difference between social and private marginal cost of imported oil is developed it is argued that there are two components to the premium the long run effect of changes in import demand on the world oil price and the external costs of oil supply disruption as related to changes in oil use using this framework as a reference point an evaluation of quantitative estimates of the premium is presented the estimates span a wide range from near zero to well over 100 per barrel and are shown to be highly sensitive to behavioural assumptions about the world oil market the article concludes by noting that an oil import fee is likely to be the best policy instrument to capture the first component of the premium and a strategic petroleum reserve the best policy instrument to capture the second component

implementation in economies with a continuum of agents we study a general implementation problem for exchange economies with a continuum of players and private information and test the robustness of the results for sequences of approximating finite economies assuming that the designer knows the distribution of the characteristics in the economy we consider continuous and unique implementation in both its equilibrium and dominant strategies versions and obtain results for general self selective first and second best allocations an upper hemicontinuity property of bayesian equilibria of approximating economies for continuous mechanisms is demonstrated using this we can for example conclude that if a given continuous mechanism implements uniquely a walrasian allocation in the continuum economy then all bayesian equilibria of large approximation economies will with probability close to one yield an allocation which is almost ex post pareto optimal

materials price increases and aggregate adjustment in an open economy a stochastic approach abstract this paper develops a stochastic macroequilibrium frameworks to analyze the differing implications of alternative types of input price disturbances the distinctions between expected and unexpected permanent and transitory nominal and real disturbances are considered the introduction of input disturbances involves a more elaborate modelling of the supply side of the economy both constant returns to scale and decreasing returns to scale technologies are considered the analysis highlights the sensitivity of the macroeconomic impacts of input price shocks to their specific type the analytical results obtained are not unambiguous and are supplemented with numerical simulations

a global model of oecd aggregate supply and demand using vector autoregressive techniques this paper presents a vector autoregressive model of the aggregate oecd economy using a theoretical model of global aggregate supply and demand relationships between industrial production cpi money supply and energy prices are examined using f tests variance decompositions and impulse response functions the empirical results are consistent with theory energy prices influence output and the price level in the short run while money influences the price level in the long run despite data problems this approach appears to be a reasonable compromise between simple arima models and the very detailed link type models

the simple macroeconomics of an oil dependent economy abstract this paper constructs and analyzes a simple macrodynamic model of a small economy that is completely dependent upon opec for oil imports the impact and dynamic behavior of wages prices output and exchange rates is analyzed under several alternative scenarios initially it is assumed that oil is denominated in dollars and the consequences of an increase in oil prices are investigated under a system of free floating in later sections the effects of this disturbance are re examined under various kinds of managed float systems

the genealogy of modern theoretical public economics from first best to second best abstract the development of second best modelling in the seventies has shaped modern theoretical economics the paper discusses some key changes in the economists conceptions the first two sections examine the efficiency equity dilemma the study of non convexities has shown that counterintuitive efficiency enhancing income redistribution might occur the introduction of asymmetric information has shed doubts on virtues of lump sum compensation the last sections focus on the intricate geometry of second best optimisation and the ambiguous value of the signals provided by the price system outside a first best world

input price shocks and the slowdown in economic growth the case of u k manufacturing this paper provides a theoretical and empirical analysis of the effects of input price shocks on economic growth with a focus on united kingdom manufacturing in the 1970s the theoretical model predicts a discrete decline in output and productivity after an input price rise and a longer run slowdown in productivity growth real wage growth and capital accumulation these features characterize the united kingdom and most other oecd economies after 1973 the empirical results confirm the important role of input prices in recent u k adjustment but also point to an important role for other supply and demand factors two types of explanations have been offered for the sharp deterioration in u k economic performance in the past decade focusing respectively on demand and supply factors a standard keynesian view holds that macroeconomic demand management has been either too expansionary or too contractionary and that rising unemployment and falling output reflect the burden of anti inflationary policies an alternative view holds that various supply shocks are the main source of the poor output performance in this interpretation higher raw material prices particularly oil competition from the newly industrializing countries nics and perhaps an independent decline in productivity growth all have lowered output growth and raised unemployment

a wavelet analysis of mean and volatility spillovers between oil and brics stock markets this paper investigates the spillover effects of volatility and shocks between oil prices and the brics stock markets using multivariate approach and wavelet analysis at different time horizons hence we combine a multivariate arma garch model and wavelet multiresolution analysis to study this phenomenon a bivariate arma 1 1 garch 1 1 cdcc student t model was joined with modwt filter to capture a broad range of possible spillover effects in mean and variances of level prices at various time horizons generally empirical results provide strong evidence of time varying volatility in all markets under study however our proposed approach shows that oil price and stock market prices are directly affected by their own news and volatilities and indirectly affected by the volatilities of other prices and wavelet scale the results show also that mean and volatility spillover effects was decomposed into many sub spillovers on different time scales according to heterogeneous investors and market participants the practical implications of this study are critical innovative and useful for the local and international investors and also for the portfolio managers they can utilize this study to formulate the optimal oil bricks stock portfolios as well as lead to more accurate predictions of volatility spillovers patterns also in developing their hedging strategies

envy freeness and distributive justice the criterion of envy freeness according to which no agent should prefer any of his neighbours allocation to his own has become a central part of the economic theory of distributive justice it essentially corresponds to the need to express an ideal of equality in societies where preferences and endowments are heterogeneous this paper surveys various formulations of the idea of envy freeness starting with the simple distribution model then adding the possibility for agents to have different native talent endowments and finally moving to models with production many classical results are displayed but emphasis is also put on recent developments mainly the ideas of minimizing envy and of absence of domination five major difficulties facing envy freeness are identified and listed as directions of future research copyright 1994 by blackwell publishers ltd

measuring the energy input substitution and output effects of energy price changes and the implications for the environment abstract previous studies of decomposition of factor inputs have limited their analysis on the estimation of substitution and output effects however this paper develops a two step approach to estimate the substitution and output effects of changes in energy demand resulting from changes in prices and further examines the implications of these effects on co2 emissions using european industrial dataset over the period 1995 2007 in our empirical estimations instead of relying only on isur model like previous studies we introduced a multilevel model which is a more befitting model to our data our analysis covers industry as a whole and for different sector types the primary results emerged from our analysis suggest a strong evidence using the multilevel model generally our results show that production inputs are substitutable we find the substitution and output effects to be negatively related to co2 emissions however the substitution effects dominate from policy perspectives our results suggest that output adjustments may not play a significant role in reducing emissions we find the overall effects of changes in energy demand to be moderate then we argue that increment in energy taxes should be complemented by cleaner factor substitution and sustainable growth to achieve a desirable carbon reduction

the macroeconomics of trade liberalization abstract this paper analyzes the short run macroeconomic consequences of trade liberalization in ldcs it is shown that linkages between the tradables and nontradables sectors the effect of imported inputs on the economy s productive structure and certain patterns of factor substitution can go a long way toward explaining the perverse contractionary effects frequently seen in liberalization programs

can opec cause inflation and recession abstract this paper addresses an issue that has been the subject of debate in the media and in academic circles the issue concerns the effect of higher oil prices initiated by opec on economic activity in oecd countries results of cointegration tests indicate that there is no long run relationship between oil prices and macroeconomic variables in oecd countries however causality testing indicates the existence of unidirectional causality from oil prices to domestic prices and output

what happened to the oil price macroeconomy relationship abstract strong evidence is found that oil prices no longer granger cause many u s macroeconomic indicator variables in data after 1973 a number of potential explanations are explored that sample stability issues are responsible that oil prices are now endogenous and that linear and symmetric specifications misrepresent the form of the oil price interaction none of these hypotheses are supported by the data the opec price increases do appear to have had significant impacts while the effects of the price declines of the 1980s are smaller and harder to characterize these results have potentially important implications for the large body of research which utilizes oil prices as an instrumental or explanatory variable

use of multicriteria decision analysis methods for energy planning problems most decision making requires the consideration of several conflicting objectives the term multiple criteria decision analysis mcda describes various methods developed for aiding decision makers in reaching better decisions energy planning problems are complex problems with multiple decision makers and multiple criteria therefore these problems are quite suited to the use of mcda a multitude of mcda methods exists these methods can be divided in three main groups value measurement models goal aspiration and reference level models and outranking models methods from all of these groups have been applied to energy planning problems particularly in the evaluation of alternative electricity supply strategies each of the methods has its advantages and drawbacks however we cannot conclude that one method generally is better suited than the others for energy planning problems a good alternative might be to apply more than one method either in combination to make use of the strengths of both methods or in parallel to get a broader decision basis for the decision maker until now studies of mcda in energy planning have most often considered energy networks with only one energy carrier more advanced energy systems with multiple energy carriers have been neglected even though this field ought to be suitable for use of mcda due to its high complexity many decision makers and many conflicting criteria

exploiting the oil gdp effect to support renewables deployment the empirical evidence from a growing body of academic literature clearly suggests that oil price increases and volatility dampen macroeconomic growth by raising inflation and unemployment and by depressing the value of financial and other assets surprisingly this issue seems to have received little attention from energy policy makers in percentage terms the oil gdp effect is relatively small producing losses in the order of 0 5 of gdp for a 10 oil price increase in absolute terms however even a 10 oil price rise oil has risen at least 50 in the last year alone produces gdp losses that could they have been averted would significantly offset the cost of increased re deployment this paper draws on the empirical oil gdp literature which we summarize to show that i by displacing gas and oil renewable energy investments can help nations avoid costly macroeconomic losses produced by the oil gdp effect and ii that these avoided losses represent a significant external macroeconomic benefit of such investments we show that a 10 increase in re share avoids gdp losses in the range of 29 53 billion in the us and the eu 49 90 billion for oecd these avoided losses offset one fifth of the re investment needs projected by the erec and half the oecd investment projected by a g 8 task force for the us the figures further suggest that each additional kw of renewables on average avoids 250 450 in gdp losses a figure that varies across technologies as a function of annual capacity factors we approximate that the offset is worth 200 kw for wind and solar and 800 kw for geothermal and biomass while we focus only on renewables the gdp offset will apply in some measure to other non fossil technologies including energy efficiency dsm and nuclear the societal valuation of non fossil alternatives must reflect these avoided gdp losses whose benefit is not fully captured by private investors this said we fully recognize that wealth created in this manner does not directly form a pool of public funds that is easily earmarked for renewables support finally the oil gdp relationship has important implications for correctly estimating direct electricity generating cost for conventional and renewable alternatives and for developing more useful energy security and diversity concepts we also address these issues

causes of the current stagflation since 1975 labour slack has been unusually high in the oecd countries and yet inflation has not diminished the less favourable mix of unemployment and rate of change of inflation which we call stagflation is explained by a fall in the feasible rate of growth of real wages unmatched by a reduction in the constant term in phillips curve to investigate this mechanism conventional wage and price equations are estimated for 19 countries and then used for simulation stagflation has been caused in roughly equal amounts by rising relative import prices and by the fall in the rate of productivity growth in the basic model the phillips curve is assumed not to adapt to falls in feasible real wage growth but in a final section an adaptive wage equation is estimated which confirms that the process of adaptation is slow

metering systems and demand side management models applied to hybrid renewable energy systems in micro grid configuration abstract this paper proposes a demand side management model integrated to a metering system for hybrid renewable energy systems in micro grid configuration the proposal is based on the management problems verified in most of this kind of renewable hybrid systems installed in brazil the main idea is the implementation of a pre paid metering system with some control functions that directly act on the consumer demand restricting the consumption proportionally to the monthly availability of renewable energy the result is a better distribution of the electricity consumption by month and by consumer preventing that only one user with larger purchasing power consumes all the renewable energy available at some time period the proportionality between the consumption and the renewable energy s availability has the objective to prevent a lack of energy stored and a high use of the diesel generator set on months of low renewable potential this paper also aims to contribute to the brazilian regulation of renewable energy systems supplying micro grids

raw materials profits and the productivity slowdown a factor price frontier framework is used to clarify the analogy of an increase decrease in raw material prices with autonomous technological regress progress factor price profiles are estimated for the manufacturing sector of the united states the united kingdom germany and japan the production model in conjunction with estimates obtained from the factor price frontier attributes much of the slowdown in manufacturing productivity to the rise in relative raw material prices part of the apparent productivity riddle may have to do with the use of double deflated national accounting measures of value added which have an inherent measurement bias

welfare bounds in the fair division problem to any anonymous division method corresponds a lower and an upper bound function they measure the impact on a given agent s utility of the other agents preferences the highest lower bound is the equal split utility the lowest upper bound is the indirect utility from equal split at a canonical price these two bounds are compatible yet any method with the elqual split lower bound exhibits the growth paradox and any method with the lowest upper bound generates envy we criticize competitive equilibrium from equal split because it puts no finite upper bound on any agent s welfare

implementation of renewable energy in scottish rural area a social study abstract nowadays renewable energy is considered one of the valuable sources of energy in the energy sector it is contributing major role in fulfilling the increasing level of global energy crisis although most of study of renewable energy is done through its technological development and a few are done in its acceptance level socially in such consequences this research considers the social acceptability of renewable energy in terms of economical environmental and cultural perspectives as a test bed scottish rural areas were considered for this social study where the areas are regarded as lacking of continuous energy supply due to weak grid and socio economic growth this research investigates the intimate and sensitive nature of the social issues in rural scotland that are important in the communities when decisions are made on renewable energy supply and demand the social interactions are investigated by means of both interviewing the local residents and distributed questionnaires among them the responses from the interviews and the questions are analyzed according to the predefined criterion of renewable energy such as willingness to accept changes of life style income and pay and education and employment

a unique informationally efficient and decentralized mechanism with fair outcomes it is shown that any informationally decentralized mechanism that realizes fair allocations over the class of classical pure exchange environments has a message space of dimension no smaller than the number of agents times the number of commodities since the equal income walrasian mechanism in which all agents take prices parametrically and maximize utility subject to the average income constraint realizes fair outcomes over the class of classical pure exchange environments and has a message space of that dimension it is informationally efficient further it is shown that it is the unique informationally efficient mechanism realizing fair allocations

review of grid tie micro generation systems without energy storage towards a new approach to sustainable hybrid energy systems linked to energy efficiency abstract this paper reviews the literature on the subject albeit approaching hybrid micro generation power systems from a systems thinking st and cybernetics standpoint viewing them as dynamically complex adaptive systems cas coupled with and supplying to a set of homes termed a sustainable block in a rural setting here homeostatic regulation hr and control play a vital role in reaching efficient equilibrium towards reconciling power supply and demand response management unlike most of the work reviewed in the literature the focus here is on supervisory control of grid connected micro generation systems without energy storage aiming towards building energy efficiency thriftiness and sustainability in energy consumption building on homeostatic control hc principles first introduced by f c schweppe in 1979 the paper explores the concepts of sustainability and sustainable hybrid energy systems shes applied to micro generation focusing on operational aspects rather than on socio economic environmental or regulatory ones a concrete theoretical model for building a shes is presented for a proposed grid connected renewable microgrid the model seeks to reconcile power supply and demand towards efficient equilibrium homeostasis proposing reward based criteria for controlling renewable electricity supply and consumption in rural communities in chile discussion and recommendations are also offered stating that energy sustainability es is essentially a systems issue and one where es is first and foremost a structural organizational and operational property which is in the very nature of the system itself it is built into it rather than explained by exogenous factors

wage gaps factor shares and real wages the relationships which link real wages capital intensity and factor shares are tested as a prelude to tests of the relationship between wage rigidities and labour market institutions evidence from seven countries indicates that the evolution of factor shares is well explained by changes in capital intensity which is itself well explained by product wages and technical progress a key implication is that changes in full employment capital labour ratios have been the dominant reason for the longer run decline of profit shares in europe and japan relative to the united states it follows that changes in cyclically adjusted factor shares provide little or no information regarding the gap between the actual real wage and its full employment value

raw materials profits and the productivity slowdown some doubts bruno 1984 argues that a fall in material input for given levels of capital and labor input can explain a measured fall in productivity growth which in most oecd countries first appeared after 1973 this comment asks the following 1 do the available output statistics show a fall in gross output as the materials hypothesis explanation of the productivity slowdown requires or do they show a fall in real value added defined as gross output less material input which indicates a fall in technical progress i conclude that the materials hypothesis cannot explain falls in productivity growth measured using gdp data but could explain partperhaps 0 5 percent per annumof the fall measured using the index of manufacturing production 2 what materials price and quantity movements have occurred to isolate the component of material prices that is exogenous common to all oecd countries and excludes energy costs i look at the u n price index for basic commodities imported by developed countries the rise in real raw material prices was much smaller in terms of its cost to importing countries than the oil price rise and by the late 1970s real industrial materials prices had fallen back to the levels of the 1960s while a general index of material input quantities is not available data for metals one major component of materials suggest that this input has fallen by about 2 percent per annum since the early 1970s relative to output and to earlier trends so statistics which directly evaluate measurement biases and material input prices and quantities suggest that substitution away from material inputs cannot explain much of the fall in productivity growth

recent oil price shock and tunisian economy abstract the objective of this paper is to study the oil prices macroeconomy relationship by the analysis of the role of subsidy policy the vector autoregression var method was employed to analyze the data over the period 1993 q1 2007 q3 the results of the model using both linear and non linear specifications indicate that there is no direct impact of oil price shock on the economic activity the shock of oil prices affects economic activity indirectly the most significant channel by which the effects of the shock are transmitted is the government s spending

energy capital substitution wage flexibility and aggregate output supply abstract this paper analyzes the relationship between factor substitution labor market conditions and aggregate output supply in order to study the transmission mechanism of energy price change to the rest of the economy it shows that the energy capital complementarity vs substitutability issue may turn out to be crucial in shaping the direction of the adjustment of aggregate output supply following energy price changes how crucial it is it is shown to depend on the beliefs of firms regarding the stock of capital on the degree to which labor markets clear and on the wage elasticity of labor supply some empirical evidence is presented about the relationship between energy price changes and output supply

strictly fair allocations in large exchange economies in this paper we introduce the concept of a strictly fair allociation and investigate the set of strictly fair allocations in large exchange economies we prove that when agents utility functions are differentiable the set of strictly fair allocations coincides with the set of equal income walrasian equilibria this is shown using both the limit theorem approach and the limit economy approach we also extend the analysis to economies that have both atoms and an atomless sector these results substantially improve upon the existing characterizations of equal income walrasian equilibria in terms of economic efficiency and economic equity

economic criteria for planning transmission investment in restructured electricity markets from an economic perspective a common criterion for assessing the merits of a transmission investment is its impacts on social welfare the underlying assumption in using this criterion is that side payments may be used to distribute the social gains among all market players in reality however since the impacts of an electricity transmission project on different players may vary such side payments are rather difficult to implement this paper focuses on different economic criteria that should be considered when planning electricity transmission investments we propose an electricity transmission investment assessment methodology that is capable of evaluating the economic impacts on the various effected stakeholders and account for strategic responses that could enhance or impede the investment s objectives we formulate transmission planning as an optimization problem under alternative conflicting objectives and investigate the policy implications of divergent expansion plans resulting from the planner s level of anticipation of strategic responses we find that optimal transmission expansion plans may be very sensitive to supply and demand parameters we also show that the transmission investments have significant distributional impact creating acute conflicts of interests among market participants we use a 32 bus representation of the main chilean grid to illustrate our results

do generation firms in restructured electricity markets have incentives to support social welfare improving transmission investments this paper examines the incentives that generation firms have in restructured electricity markets for supporting long term transmission investments in particular we study whether generation firms which arguably play a dominant role in the restructured electricity markets have the incentives to fund or support incremental social welfare improving transmission investments we examine this question in a two node network and explore how such incentives are affected by the ownership of financial transmission rights ftrs by generation firms in the analyzed two node network we show both i that the net exporter generation firm has the correct incentives to increase the transmission capacity incrementally up to a certain level and ii that although a policy that allocates ftrs to the net exporter generation firm can be desirable from a social point of view such a policy would dilute the net importer generation firm s incentives to support transmission expansion moreover if all ftrs were allocated or auctioned off to the net exporter generation firm then it is possible to increase both consumer surplus and social welfare while keeping the net exporter generation firm revenue neutral

vickrey clarke groves mechanisms and perfect competition abstract we present a game theoretic mechanism characterization of perfect competition we prove the perfectly competitive mechanism is the only pareto optimal individually rational dominant strategy allocation mechanism thus perfect competition is uniquely capable of efficiently and non coercively solving the incentive bargaining problem when there is incomplete information i e when each individual knows his own tastes and production possibilities better than anyone else we also show one can interpret any dominant strategy demand revealing mechanism as working because it mimics the reward scheme that characterizes the perfectly competitive market namely the marginal product reward scheme

fair allocations in large economies the purpose of this paper is the study of problems of equity in an economy with many agents conditions are given under which every equitable and pareto optimal allocation is a competitive equilibrium with equal incomes for all agents the results are also of potential relevance for the literature on incentive compatibility since the allocations that are obained through incentive mechanisms in large economies turn out to be equitable
