monetary policy asset prices and liquidity in over the counter markets we develop a model where agents can allocate their wealth between a liquid asset which can be used to purchase consumption goods and an illiquid asset which represents a better store of value should a consumption opportunity arise agents may visit a frictional over the counter secondary asset market where they can exchange illiquid for liquid assets we characterize how monetary policy affects both the issue price and the secondary market price of the asset we also show that in contrast to conventional wisdom search and bargaining frictions in the secondary asset market can improve welfare if inflation is low

the term structure of illiquidity premia abstract we investigate the term structure of bond market illiquidity premia and show that the term structure varies greatly over time short and long end are strictly separated suggesting that different economic factors drive different parts of the term structure we propose a stylized theoretical model which implies that current trading needs of investors determine the short end the long term risk of being forced to liquidate bond positions determines the long end empirical evidence supports these predictions while short term liquidation risk captured by asset market volatilities drives the short end the long end depends on the long term economic outlook

electricity demand estimates under increasing block rates using price variables calculated at observed consumption levels this study finds significant bias in ordinary least squares estimates of price elasticities of electricity demand the bias is most severe for specifications using observed average price the finding is important for future econometric work since this type of rate structure is becoming more common the evidence indicates that inappropriate use of ordinary least squares ols overestimates that rate structure premium effect on demand and may underestimate the marginal price elasticity the use of an instrumental variables technique applied to actual rate schedules proves consistent parameter estimates regardless of the rate structure 20 references 3 tables

on the causal dynamics between emissions nuclear energy renewable energy and economic growth this paper examines the causal relationship between co2 emissions nuclear energy consumption renewable energy consumption and economic growth for a group of 19 developed and developing countries for the period 1984 2007 using a panel error correction model the long run estimates indicate that there is a statistically significant negative association between nuclear energy consumption and emissions but a statistically significant positive relationship between emissions and renewable energy consumption the results from the panel granger causality tests suggest that in the short run nuclear energy consumption plays an important role in reducing co2 emissions whereas renewable energy consumption does not contribute to reductions in emissions this may be due to the lack of adequate storage technology to overcome intermittent supply problems as a result electricity producers have to rely on emission generating energy sources to meet peak load demand

technology invention and diffusion in residential energy consumption a stochastic frontier approach traditional large appliances absorb a large share of residential electricity consumption and represent important targets of energy policy strategies aimed at achieving energy security despite being characterized by rather mature technologies this group of appliances still offers large potential in terms of efficiency gains due to their pervasive diffusion in this paper we analyse the electricity consumption of a set of four traditional white goods in a panel of ten eu countries observed over 21 years 1990 2010 with the aim of disentangling the amount of technical efficiency from the overall energy saving the technical efficiency trend is modelled through a set of technology components representing both the invention and adoption process by the means of specific patents weighted by production and bilateral import flows which allows to overcome the rigid stochastic frontier framework in modelling the effect of technical change our results show that the derived energy demand and inefficiency trends are both related to changes in the amount of available technology embodied in energy efficient appliances the effect is significant both in its domestic and international components and suggests an active role of innovation and trade policies for achieving efficiency targets which directly impact the amount of electricity consumed by households

dynamic portfolio choice with frictions abstract we show how portfolio choice can be modeled in continuous time with transitory and persistent transaction costs multiple assets multiple signals predicting returns and general signal dynamics the objective function is derived from the limit of discrete time models with endogenous transaction costs due to optimal dealer behavior we solve the model explicitly and the intuitive solution is also the limit of the solutions of the corresponding discrete time models we show how the optimal high frequency trading strategy depends on the nature of the trading costs which in turn depend on dealers inventory dynamics finally we provide equilibrium implications and illustrate the model s broader applicability to micro and macro economics monetary policy and political economy

competing for order flow in otc markets we develop a model of a two sided asset market in which trades are intermediated by dealers and are bilateral dealers compete to attract order flow by posting the terms at which they execute trades which can include prices quantities and execution times and investors direct their orders toward dealers that offer the most attractive terms of trade equilibrium outcomes have the following properties first investors face a trade off between trading costs and speeds of execution second the asset market is endogenously segmented in the sense that investors with different asset valuations and different asset holdings will trade at different speeds and different costs for example under a leontief technology to match investors and dealers per unit trading costs decrease with the size of the trade in accordance with the evidence from the market for corporate bonds third dealers implicit bargaining powers are endogenous and typically vary across sub markets finally we obtain a rich set of comparative statics both analytically by studying a limiting economy where trading frictions are small and numerically for instance we find that the relationship between trading costs and dealers bargaining power can be hump shaped

a search based theory of the on the run phenomenon we propose a model in which assets with identical cash flows can trade at different prices infinitely lived agents can establish long positions in a search spot market or short positions by first borrowing an asset in a search repo market we show that short sellers can endogenously concentrate in one asset because of search externalities and the constraint that they must deliver the asset they borrowed that asset enjoys greater liquidity a higher lending fee specialness and trades at a premium consistent with no arbitrage we derive closed form solutions for small frictions and provide a calibration generating realistic on the run premia

rural electrification its future in the usa abstract the us government has been involved in providing financial support for rural electrification for nearly 50 years this support combined with the creation of member owned electric cooperatives in 46 states led to a dramatic growth in the number of rural households receiving central station service through organizations such as the agency for international development and the world bank rural electric cooperatives have become established world wide this article provides a review of the political and economic climate which currently faces us cooperatives and compares this position with the rural electric systems in other countries the implications of the forecasts of the us cooperatives load growth developed from the oak ridge national laboratory rural electric energy demand ornl reed model are evaluated a short description of the econometric model which is estimated for five us regions using state level annual data from 1969 to 1979 is included the article concludes with an outline of the probable impact of several policy options on the growth of us cooperatives

residential electricity demand dynamics in turkey abstract this article provides fresh empirical evidences for the income and price elasticies of the residential energy demand both in the short run and long run for turkey over the period 1968 2005 using the bounds testing procedure to cointegration the computed elasticities of income and price are consistent with the previous studies and as expected the long run elasticities are greater than the short run elasticities an augmented form of granger causality analysis is implemented among residential electricity income price and urbanization in the long run causality runs interactively through the error correction term from income price and urbanization to residential energy but the short run causality tests are inconclusive the parameter stability of the short run as well as long run coefficients in the residential energy demand function are tested the results of these tests display a stable pattern

slow moving capital we study three cases in which specialized arbitrageurs lost significant amounts of capital and as a result became liquidity demanders rather than providers the effects on security markets were large and persistent prices dropped relative to fundamentals and the rebound took months while multi strategy hedge funds who were not capital constrained increased their positions a large fraction of these funds actually acted as net sellers consistent with the view that information barriers within a firm not just relative to outside investors can lead to capital constraints for trading desks with mark to market losses our findings suggest that real world frictions impede arbitrage capital this abstract was borrowed from another version of this item

historical construction costs of global nuclear power reactors the existing literature on the construction costs of nuclear power reactors has focused almost exclusively on trends in construction costs in only two countries the united states and france and during two decades the 1970s and 1980s these analyses koomey and hultman 2007 grubler 2010 and escobar rangel and leveque 2015 study only 26 of reactors built globally between 1960 and 2010 providing an incomplete picture of the economic evolution of nuclear power construction this study curates historical reactor specific overnight construction cost occ data that broaden the scope of study substantially covering the full cost history for 349 reactors in the us france canada west germany japan india and south korea encompassing 58 of all reactors built globally we find that trends in costs have varied significantly in magnitude and in structure by era country and experience in contrast to the rapid cost escalation that characterized nuclear construction in the united states we find evidence of much milder cost escalation in many countries including absolute cost declines in some countries and specific eras our new findings suggest that there is no inherent cost escalation trend associated with nuclear technology

rural residential demand for electricity a simulateous equation partial adjustment model of rural electric cooperatives recs residential demand for electricity highlights the characteristics of rural energy demand and the tendency of rural customers to make greater short term adjustments to price changes the differences between rural and urban use patterns however are not consistent throughout the country the model also points to how changes in the number of households and per capita income can affect rural demand in planning for the future the cooperatives must identify and be aware of the unique features of their service areas not only in respect to regional characteristics but also in terms of the distinctive patterns or rural demand 17 references

trading in derivatives when the underlying is scarce abstract regulatory restrictions and market frictions can constrain the aggregate quantity of long and short positions in a security when these constraints bind we refer to the security as scarce and its price becomes distorted relative to its value in a frictionless market we show that an otherwise redundant derivative can reduce the price distortion of the underlying security by relaxing its scarcity we also show that it is especially important to analyze the underlying and derivative markets jointly when evaluating the impact of regulation such as short sales bans and position limits in derivatives that restricts trade

estimation of residential electricity demand in hong kong under electricity charge subsidies abstract over the past decade the hong kong hk government provided electricity charges subsidies for residential accounts to alleviate the burden of inflation and later the burden of economic downturn in this study we estimate an econometric model of residential electricity demand and test the existence of a stable long run relationship for the period 1980 2016 while accounting for the relief measures set out by the hk government since 2008 empirical results suggest that there exists a long run relationship among residential electricity consumption electricity price income per capita and weather variables temperature or cooling degree days in the absence of electricity charge subsidies the demand is found to be both price and income inelastic on the other hand hk s residential electricity consumers are unresponsive to price and income changes when electricity subsidies are in place following its new carbon reduction plan hk is gradually phasing out coal for electricity generation to replace it mainly with natural gas our results suggest that new residential electricity charge subsidies can lessen the effectiveness of6 climate policies aimed at reducing electricity consumption through increases in the electricity price

short and long run elasticities in us residential electricity demand a co integration approach abstract co integration techniques show promise in the analysis of short and long run effects of economic variables on energy use we use these techniques to develop an error correction model of annual us residential electricity demand we construct equipment stock indices and estimate the model for 1949 1993 our analysis suggests a structural shift in consumption during the 1960s we discuss reasons for this shift report the short and long run elasticities provide forecasts for 1994 1995 and compare the model s forecasts with other published forecasts

equilibrium pricing and trading volume under preference uncertainty information collection processing and dissemination financial institutions is challenging this can delay the observation by traders of the exact capital charges and constraints of their institution during this delay traders face preference uncertainty in this context we study optimal trading strategies and equilibrium prices in a continuous centralized market we focus on liquidity shocks during which preference uncertainty is likely to matter most preference uncertainty generates allocative ineficiency but need not reduce prices traders progressively learning about the preferences of their institution conduct round trip trades which generate excess volume relative to the frictionless market in a cross section of liquidity shocks the initial price drop is positively correlated with total trading volume across traders the number of round trips is negatively correlated with trading profits and average inventory

a nuclear to gas transition in south korea is it environmentally friendly or economically viable abstract given the limited potential for renewable energy and high population density of south korea nuclear has been an essential electricity generation option for supply of reliable power whilst reducing greenhouse gas emissions and mitigating air pollution however the recently elected 2017 south korean government has a policy committing them to a phase out of nuclear and coal offset by an increase in the share of variable renewables however the main component of the power transition is set to be liquefied natural gas lng due to technical and economic barriers facing large scale renewables it is therefore critical for south korea to develop an evidence based perspective on the details of the transition before any future energy policy is decided here we review i the national role of renewable sources given technical and economic limitations in south korea ii potential environmental and economic issues with gas and iii potential barriers of and benefits to a nuclear pathway our conclusion is that given the geographical and economic limitations facing south korea and the need to reduce carbon emissions cost effectively a nuclear pathway coupled with a moderate renewable share offers the most viable policy with a gas focused energy future being neither environmentally friendly nor economic

historical energy price shocks and their changing effects on the economy abstract the purpose of this paper is to identify the changes in the impact of energy shocks on economic activity with an interest in assessing if an economy s vulnerability and resilience to shocks improved with economic development using data on the united kingdom over the last three hundred years the paper identifies supply aggregate demand and residual shocks to energy prices and estimates their changing influence on energy prices and gdp the results suggest that the impacts of supply shocks rose with its increasing dependence on coal and declined with its partial transition to oil however the transition from exporting coal to importing oil increased the negative impacts of demand shocks more generally the results indicate that improvements in vulnerability and resilience to shocks did not progress systematically as the economy developed instead the changes in impacts depended greatly on the circumstances related to the demand for and supply of energy sources if these experiences are transferable to future markets a transition to a diversified mix of renewable energy is likely to reduce vulnerability and increase resilience to energy price shocks

liquidity premia in dynamic bargaining markets abstract this paper develops a search theoretic model of the cross sectional distribution of asset returns abstracting from risk premia and focusing exclusively on liquidity in contrast with much of the transaction cost literature it is not assumed that different assets carry different exogenously specified trading costs instead different expected returns due to liquidity are explained by the cross sectional variation in tradeable shares the qualitative predictions of the model are consistent with much of the empirical evidence

optimal asset allocation with fixed term securities we investigate the optimal asset allocation of an investor who can invest in a fixed term security that is only traded at time 0 using a generalized martingale approach we solve the investor s optimal portfolio problem determine the optimal allocation to fixed term securities and provide a representation of trading strategies in terms of a liquidity related derivative we apply our approach to two benchmark scenarios fixed term fixed rate bank deposits and unspanned closed end securities that can only be traded at time 0 we show that both can be key parts of the investor s optimal asset mix and we investigate the dependence of optimal allocations to fixed term investments implied liquidity premia and other characteristics on the underlying model parameters

systemic illiquidity in the federal funds market this paper shows how the intra day allocation and pricing of overnight loans of federal funds reflect the decentralized inter bank market in which these loans are traded a wouldbe borrower or lender typically finds a counterparty institution by direct bilateral contact once in contact say by telephone the two counterparties to a potential trade negotiate terms that reflect their incentives for borrowing or lending as well as the attractiveness of their respective options to forego a trade and to continue shopping around this overthe counter otc pricing and allocation mechanism is quite distinct from that of most centralized markets such as an electronic limit order book market in which every order is anonymously exposed to every other order with a centralized order crossing algorithm while there is a significant body of research on the micro structure of specialist and limit order book markets most otc markets do not have comprehensive transactionslevel data available for analysis the federal funds market is a rare exception we go beyond a previous study by craig furfine 1999 of the microstructure of the federal funds market by modeling how the likelihood of matching a particular borrower with banking studies federal reserve bank of new york 33 liberty street new york ny 10045 we are grateful for support and data from the federal reserve bank of new york and for comments from guillaume plantin jamie mcandrews craig furfine michael fleming and anonymous federal funds traders we have also benefited from comments by andrew metrick jeremy stein ken french larry harris owen lamont john taylor and randy westerfield the views expressed here are not necessarily those of the federal reserve bank of new york or the federal reserve system

electricity consumption in g7 countries a panel cointegration analysis of residential demand elasticities this article applies recently developed panel unit root and panel cointegration techniques to estimate the long run and short run income and price elasticities for residential demand for electricity in g7 countries the panel results indicate that in the long run residential demand for electricity is price elastic and income inelastic the study concludes that from an environmental perspective there is potential to use pricing policies in the g7 countries to curtail residential electricity demand and thus curb carbon emissions in the long run

electricity consumption and metropolitan economic performance in guangzhou 1950 2013 abstract this study analyzes the relationship between electricity consumption and metropolitan economic growth for guangzhou china using 64 years of annual frequency data the capital stock is used as a control variable because of its role in mediating the relationship between energy utilization and economic output empirical results indicate unidirectional granger causality from electricity consumption to metropolitan economic performance in the short run this is consistent with the argument that dependable electricity infrastructure and service can play a vital role in facilitating economic growth implications for conservation efforts and regional development are discussed

the over the counter theory of the fed funds market a primer we present a dynamic over the counter model of the fed funds market and use it to study the determination of the fed funds rate the volume of loans traded and the intraday evolution of the distribution of reserve balances across banks we also investigate the implications of changes in the market structure as well as the effects of central bank policy instruments such as open market operations the discount window lending rate and the interest rate on bank reserves

portfolio choice and pricing in illiquid markets abstract this paper studies portfolio choice and pricing in markets in which immediate trading may be impossible it departs from the literature by removing restrictions on asset holdings and finds that optimal positions depend significantly and naturally on liquidity when expected future liquidity is high agents take more extreme positions given that they do not have to hold those positions for long when they become undesirable consequently larger trades should be observed in markets with more frequent trading liquidity need not affect the price significantly however because liquidity has offsetting impacts on different agents demands this result highlights the importance of unrestricted portfolio choice the paper draws parallels with the transaction cost literature and clarifies the relationship between the price level and the realized trading frequency in this literature

trade dynamics in the market for federal funds we develop a model of the market for federal funds that explicitly accounts for its two distinctive features banks have to search for a suitable counterparty and once they have met both parties negotiate the size of the loan and the repayment the theory is used to answer a number of positive and normative questions what are the determinants of the fed funds rate how does the market reallocate funds is the market able to achieve an efficient reallocation of funds we also use the model for theoretical and quantitative analyses of policy issues facing modern central banks

perception of price when price information is costly evidence from residential electricity demand a bstract residential electricity consumption is an example of a good for which it is costly to determine marginal price since price changes with the quantity purchased according to multistep block rate schedules this paper investigates the effect of the price information problem on consumers price perceptions an alternative hypothesis of average price perception is tested against the marginal price postulate which assumes wellinformed consumers the model which includes a price perception variable allows the estimation of the price to which consumers actually respond the empirical results support the hypothesis that consumers respond to average price perceived from the electricity bill

residential electricity consumption in seattle abstract recent empirical research for different regions of the united states indicates that residential electricity may be an inferior good whose consumption is negatively correlated with income that is a provocative result that runs counter to what many earlier econometric studies indicate given that it makes sense to examine how electricity consumption behaves in different regional service areas even if residential electricity is an inferior good whose usage declines as income rises there is no guarantee that this will be the case across all service areas this study examines residential electricity consumption for seattle washington the largest metropolitan economy in the northwestern region of the united states results from a dynamic error correction modeling approach indicate that residential electricity consumption reacts in statistically significant manners to changes in real price real income and cold weather in the short run residential electricity is a normal good in this metropolitan economy in the long run residential electricity appears to be an inferior good in seattle all else equal whenever real per capita income growth exceeds 1 2 per capita residential electricity usage declines in seattle

portfolio choice with illiquid assets we present a model of optimal allocation to liquid and illiquid assets where illiquidity risk results from the restriction that an asset cannot be traded for intervals of uncertain duration illiquidity risk leads to increased and state dependent risk aversion and reduces the allocation to both liquid and illiquid risky assets uncertainty about the length of the illiquidity interval as opposed to a deterministic nontrading interval is a primary determinant of the cost of illiquidity we allow market liquidity to vary from normal periods when all assets are fully liquid to illiquidity crises when some assets can only be traded infrequently the possibility of a liquidity crisis leads to limited arbitrage in normal times investors are willing to forgo 2 of their wealth to hedge against illiquidity crises occurring once every 10 years this paper was accepted by itay goldstein finance

liquidity and risk management this paper provides a model of the interaction between risk management practices and market liquidity on one hand tighter risk management reduces the maximum position an institution can take thus the amount of liquidity it can offer to the market on the other hand risk managers can take into account that lower liquidity amplifies the effective risk of a position by lengthening the time it takes to sell it the main result of the paper is that a feedback effect can arise tighter risk management reduces liquidity which in turn leads to tighter risk management etc this can help explain sudden drops in liquidity and since liquidity is priced in prices in connection with increased volatility or decreased risk bearing capacity this abstract was borrowed from another version of this item

frictional intermediation in over the counter markets we extend duffie et al s 2005 search theoretic model of over the counter otc asset markets allowing for a decentralized inter dealer market with arbitrary heterogeneity in dealers valuations or equivalently inventory costs we develop a solution technique that makes the model fully tractable and allows us to derive in closed form theoretical formulas for key statistics analysed in empirical studies of the intermediation process in otc markets a calibration to the market for municipal bonds allows us to quantify important unobservable characteristics of this market including the severity of search and bargaining frictions and the nature of heterogeneity across dealers we use our calibrated model to study the effect of these market characteristics on total welfare and the distribution of gains from trade across customers and dealers

forecast of electricity consumption in cyprus up to the year 2030 the potential impact of climate change abstract this paper provides a forecast of electricity consumption in cyprus up to the year 2030 based on econometric analysis of energy use as a function of macroeconomic variables prices and weather conditions if past trends continue electricity use is expected to triple in the coming 20 25 years with the residential and commercial sectors increasing their already high shares in total consumption besides this reference scenario it was attempted to assess the impact of climate change on electricity use according to official projections the average temperature in the eastern mediterranean is expected to rise by about 1 c by the year 2030 using our econometrically estimated model we calculated that electricity consumption in cyprus may be about 2 9 higher in 2030 than in the reference scenario this might lead to a welfare loss of 15 million euros in 2020 and 45 million euros in 2030 for the entire period 2008 2030 the present value of costs may exceed 200 million euros all expressed in constant euros of 2007 moreover we assessed the additional peak electricity load requirements in the future because of climate change extra load may amount to 65 75 megawatts mw in the year 2020 and 85 95 mw in 2030

the dynamic properties of financial market equilibrium with trading fees we incorporate trading fees in a long horizon dynamic general equilibrium model in which traders optimally and endogenously decide when and how much to trade a full characterization of equilibrium is provided which allows us to study the dynamics of equilibrium trades equilibrium asset prices and rates of return in the presence of trading fees we exhibit the effect of trading fees on deviations from the consumption capm and analyze the pricing of endogenous liquidity risk we compare for the same shocks the impulse responses of this model to those of a model in which trading is infrequent because of trader inattention the current version reflects material that was previously in two papers w21421 and w19155

an empirical analysis of electricity consumption in cyprus abstract the paper presents the first empirical analysis of electricity consumption in cyprus using annual data from 1960 to 2004 we have examined electricity use in the residential and the services sectors which are the fastest growing electricity consumers in the island and its interaction with income prices and the weather the analysis was performed with the aid of time series analysis techniques such as unit root tests with and without a structural break in levels cointegration tests vector error correction models granger causality tests and impulse response functions results show long term elasticities of electricity use above unity for income and of the order of 0 3 to 0 4 for prices in the short term electricity consumption is rather inelastic mostly affected by weather fluctuations granger causality tests confirm exogeneity of electricity prices and bidirectional causality between residential electricity consumption and private income the commercial sector is less elastic and reverts faster to equilibrium than the residential sector despite the relatively small sample size results reported here are quite robust and can be used for forecasts and policy analyses

transaction costs and asset prices a dynamic equilibrium model in this article we study the effects of transaction costs on asset prices we assume an overlapping generations economy with a riskless liquid bond and many risky stocks carrying proportional transaction costs we obtain stock prices and turnover in closed form surprisingly a stock s price may increase in transaction costs and a more frequently traded stock may be less adversely affected by an increase in transaction costs calculations based on the marginal investor overestimate the effects of transaction costs for realistic parameter values transaction costs have very small effects on stock prices but large effects on turnover

how much is enough an integrated examination of energy security economic growth and climate change related to hydropower expansion in brazil abstract reconciling economic growth and energy supply with the reduction of greenhouse gas emissions and other goals for environmental protection is a major challenge for emerging economies such as brazil establishing energy security standards consistent with realistic economic growth projections while considering climate change requires complex calculations and relies upon risky assumptions yet such calculations and decisions must be made to avoid future energy shortages and economic crises this paper discusses the current dilemma concerning planning and decision making for the brazilian electric sector considering the construction of hydroelectric power plants in the amazon region energy security requirements projected economic growth and climate change feedbacks

leaning against the wind during financial disruptions market makers provide liquidity by absorbing external selling pressure they buy when the pressure is large accumulate inventories and sell when the pressure alleviates this paper studies optimal dynamic liquidity provision in a theoretical market setting with large and temporary selling pressure and order execution delays i show that competitive market makers offer the socially optimal amount of liquidity provided they have access to sufficient capital if raising capital is costly this suggests a policy role for lenient central bank lending during financial disruptions

estimating residential demand for electricity in the united states 1965 2006 abstract this paper examines the residential demand for electricity in the us economy as a function of the per capita income the price of electricity the price of oil for heating purposes the weather conditions and the stock of occupied housing over the period 1965 2006 this paper has two novelties first the occupied stock of houses as a proxy for the stock of electrical appliances and second the identification of a possible equilibrium relationship among the variables is ascertained through the recently advanced ardl approach to cointegration our empirical findings give support to a stable long run relationship implying also short run and long run elasticities whose size and sign are comparable to other similar studies

philippine electric demand and equivalence scales the literature on residential electricity demand in developing countries is small based principally on latin american experience and with the exception of westley 24 25 employs highly aggregated data price elasticities are generally found to be less than u s elasticities 26 39 one explanation by westley is that energy substitution possibilites may be more limited in latin american countries he further suggests that since the household budget share of electricity is smaller in these countries the slutsky equation would imply an own price elasticity closer to the compensated elasticity and less influenced by income elasticity as a refinement westley also suggests that substitute fuels are more available in rural versus urban settings and that as a result price elasticity may be larger empirically however he found no difference 25 257 261 26 125 income elasticity findings on the other hand are varied pindyck s 17 evidence and inferences are that these elasticities are larger in developing than developed countries and in both cases decline with per capita income bemdt and samaniego 3 find results for mexico that agree in the first part with pindyck in fact when electric system connection rates are considered they suggest that their findings show an income elasticity greater than one 2

average and marginal price changes and the demand for electricity an econometric study the empirical literature on the demand for electricity has hitherto failed to adequately deal with increasing block pricing while it is desirable in principle to include the entire price schedule in the demand function the convention has been to include as an argument either an average or a marginal price yet use of either to the exclusion of the other one leads inter alia to biased estimates of own price elasticity with this in mind a residential demand function is estimated employing both average and marginal price while a number of interesting results emerge it is significant that the coefficient on marginal price is right that is the expected inverse relationship between the quantity of electricity demanded and the marginal price it obtains on the other hand the positive sign on average price is troubling because average price is in this case exactly the same concept as the intra marginal payment a change in average price is exactly the same concept as a change in real income t
