analysis of energy intensity in japan this study discusses the causes of the increase in japan s energy intensity defined as energy consumption divided by gdp since the early 1990s the significant reduction in japan s energy intensity ceased in the early 1980s and has even slightly increased since the early 1990s indicating that japan seemingly stopped taking aggressive action to improve energy use however further analysis at prefecture level and sector level provides additional insight on energy intensity trends to analyze the causes of the increase in japan s energy intensity energy intensity is decomposed into energy efficiency improvements in energy efficiency and energy activity structural changes from the secondary sector to the tertiary sector of the economy our result indicates that the non uniform energy intensity trends between prefectures are attributed to a high variability in energy efficiency at sector level we estimate the income elasticity of energy consumption in each sector and find that a structural change in energy consumption behaviors occurred in all sectors at different time points the industrial sector and commercial sector became less energy efficient after 1981 and 1988 respectively which is presumably responsible for the deterioration of japan s energy intensity since the early 1990s

land acquisition political intervention fragmentation and voice abstract this paper develops a simple dynamic framework of holdout in land acquisition both with and without political intervention where holdout arises because of the landowners inability to manage large sums of money and consequent lack of inter temporal consumption smoothing in case of sale formalized as landowners having sophisticated present biased preferences we then use this framework to analyze two issues of interest political intervention and fragmentation we find that politicization cannot improve efficiency if holdout is landowner induced and may even increase inefficiency if holdout is buyer induced further the extent of politicization depends on whether it involves voice for non members or not turning to the effects of fragmentation we find that while it increases holdout in the absence of politicization in the presence of politicization this effect may however be reversed

fuel consumption for road transport in the usa abstract this study provides both a historical analysis of fuel demand for road transport and an example of using econometric results for projections fuel consumption by all motor vehicles in the usa has been analysed by splitting total demand into passenger car truck and other demands distance travelled and fuel efficiency equations have been estimated for both the passenger car fleet and trucks an essentially five equation model has been constructed and used to simulate likely fuel demand patterns up to 1990

holdout existence information and contingent contracting abstractthe holdout problem permeates policy discussions of legal issues involving bargaining for land acquisition and more broadly impacts multilateral bargaining between agents laboratory experiments investigate the scope of the holdout problem the research strategy incorporates as treatment variables available information and the exposure problem arising from the unavailability of contingent contracts an examination reveals that holdout can reliably produce large inefficiencies and lost opportunities for mutually advantageous trade the introduction of contingent contracts facilitates successful bargaining however buyers are not made significantly better off by contingent contracts

comparative statics in a simple class of strategic market games this paper investigates the effects of entry in two sided markets where buyers and sellers act strategically applying new tools from supermodular optimization games sufficient conditions for different comparative statics results are obtained while normality of one good is sufficient for the equilibrium price to be increasing in the number of buyers normality of both goods is required for equilibrium bids and sellers equilibrium utilities to be increasing in the number of buyers when the economy is replicated normality of both goods and gross substitutes guarantee that the equilibrium of the strategic market game converges monotonically in quantities to the competitive equilibrium simple counter examples are provided to settle other potential conjectures of interest c 2007 elsevier inc all rights reserved

stability of us petroleum refinery response to relative product prices abstract the stability of the response of petrol s share of petroleum product mix to changes in petroleum product prices is investigated in this paper by using the cooley and prescott varying parameter technique on us data a significant response to changes in product prices is found when the price of petrol increased by 1 its share of product mix increased by over 0 08 while increases in residual and distillate fuel oil prices decreased petrol s share this response was found to be stable from 1936 to 1976 with the war years excluded thus the usa with ample cracking and downstream conversion capacity has been able to respond consistently to the variations in product prices although the model proved stable less precise and less elastic estimates when the period 1974 76 was included suggest less consistent responses under conditions of large price changes heavier crude oils increased unleaded petrol production and crude oil shortages

accounting for asymmetric price responses and underlying energy demand trends in oecd industrial energy demand abstract this paper explores the way technical progress and improvements in energy efficiency are captured when modelling oecd industrial energy demand the industrial sectors of the developed world involve a number of different practices and processes utilising a range of different technologies consequently given the derived demand nature of energy it is vital when modelling industrial energy demand that the impact of technical progress is appropriately captured however the energy economics literature does not give a clear guide on how this can be achieved one strand suggests that technical progress is endogenous via asymmetric price responses whereas another strand suggests that it is exogenous more recently it has been suggested that potentially there is a role for both endogenous technical progress and exogenous technical progress and consequently the general model should be specified accordingly this paper therefore attempts to model oecd industrial energy demand using annual time series data over the period 1962 2010 for 15 oecd countries using the structural time series model framework the general specifications allow for both asymmetric price responses for technical progress to impact endogenously and an underlying energy demand trend for technical progress and other factors to impact exogenously but in a non linear way the results show that almost all of the preferred models for oecd industrial energy demand incorporate both a stochastic underlying energy demand trend and asymmetric price responses this gives estimated long run income elasticities in the range of 0 34 to 0 96 estimated long run price maximum elasticities in the range of 0 06 to 1 22 estimated long run price recovery elasticities in the range of 0 00 to 0 27 and estimated long run price cut elasticities in the range of 0 00 to 0 18 furthermore the analysis suggests that when modelling industrial energy demand there is a place for endogenous technical progress and an exogenous underlying energy demand trend consequently it is argued that any modelling strategy should start by including both and only imposed restrictions if accepted by the data

implied elasticities in some uk energy projections abstract this paper presents some estimates of price and income elasticities for the demand for total delivered energy to final users in the uk it compares these with the elasticities implicit in three energy projections for the uk and finds that the implicit elasticities in official projections are not obviously consistent with recent experience while the price elasticity implicit in an unofficial low energy projection is not obviously implausible these tentative but important conclusions are not in any way weakened by looking at other estimates

trade fragmentation and coordination in strategic market games abstract this paper analyzes the incentives to trade and the validity of the law of one price in three strategic market games with multiple trading posts in bilateral oligopolies where traders have corner endowments in one commodity all agents participate in all the markets the law of one price holds in bilateral oligopolies and in the buy or sell market game where equilibrium strategies are locally unique when traders can simultaneously buy and sell on every market the law of one price fails and the set of equilibrium prices generically has the same dimension as the number of active markets journal of economic literature classification numbers d43 d51

demand for gasoline in kuwait an empirical analysis using cointegration techniques abstract this paper estimates the demand for gasoline in kuwait for the period 1970 1989 using a cointegration and error correction model ecm it is found that gasoline demand is inelastic with respect to price in the short and long run and while it is elastic in the long run gasoline demand is inelastic with respect to income in the short run this suggests that gasoline demand response to income changes is higher in the long run than in the short run furthermore gasoline consumption adjusts towards its long run level with about 52 of the adjustment occurring in the first year

income and price elasticities of energy consumption in egypt a time series analysis abstract the purpose of this paper is to provide empirical estimates of the price and income elasticities of energy consumption in egypt it fills an important gap since policy discussion of energy pricing issues has so far been based more on assumptions than on hard evidence the paper shows that the real relative price of energy has been falling steadily since 1972 while per capita energy consumption rose some 50 over the decade 1972 81 evidence produced in this exercise indicates quite clearly that price and income elasticities of energy consumption are significantly much lower than was generally believed

the reliability of aggregate energy demand functions an application of statistical specification error tests abstract the paper examines the unbiasedness and efficiency of various energy elasticity estimates by means of statistical specification error tests the model selection procedure is applied to energy consumption data of eight industrialized countries it is found that models which describe dynamic behaviour by including the lagged dependent variable among the regressors are most frequently accepted and that long term income effects are important for all countries strong differences among countries prevail concerning the appropriateness of including a time trend elasticities derived from accepted models differ considerably among countries

short and long run elasticities in energy demand a cointegration approach abstract short and long run energy demand elasticities are estimated on danish annual data for 1948 1990 energy consumption the real price of energy and real gdp appear to be non stationary variables cointegration and error correction methods are therefore applied all estimated parameters have the expected signs and magnitudes and no evidence is found of a structural break in energy demand caused by the increases in real energy prices since 1973 74

state gasoline consumption in the usa an econometric analysis abstract this paper examines the determinants of state gasoline consumption per household in the usa using pooled time series cross section data for the period 1966 1980 it was found that gasoline price fuel efficiency of vehicle stock percentage of population in metropolitan areas and non automobile transport modes have negative effects on consumption while per capita income number of vehicles non agricultural employment per household age 18 44 warm weather visits by out of state automobiles and share of buses and trucks have positive effects on consumption holding constant the size of vehicle stock and its fuel efficiency characteristics the short run price elasticity of gasoline was found to be 0 321 for the period 1966 1973 and 0 106 for the period 1974 1980 it was also found that gasoline demand experienced a temporary shift both in the intercept and in the price coefficient during the shortages of 1974 and 1979 and had undergone a permanent shift in the same parameters during the post embargo period

interfuel competition in the industrial sector of seven oecd countries abstract the purpose of this article is to present an analysis of interfuel substitution in the industrial sector of seven major oecd countries the united states canada japan germany france the united kingdom and italy over the 1960 1993 period translog models are used to provide estimates of price elasticities from annual data for each country results outline the weakness of price elasticities and changes in behaviour over the last 35 years and show evidence of asymmetric effects since the collapse of oil prices in 1986 substitution has stopped industrial energy demand and oil consumption have stagnated interfuel substitution is widely induced by events other than relative price changes energy policy political and institutional constraints changes in economic activity characteristics within individual country sectors

land aggregation using contingent and guaranteed payments this article explores the use of alternative payment mechanisms to overcome the holdout problem when multiple parcels of land must be acquired to complete a real estate development project purchase offers contingent upon successful land aggregation are compared to combination offers containing both guaranteed and contingent payments to determine which approach better mitigates holdout the distribution of gains between developers and landowners is also examined the results of a series of economic experiments suggest that contingent offers expedite land aggregation but developer payoffs are higher when combination offers are used the results offer insight to real estate developers participating in land aggregation and inform government entities considering the necessity of public sector intervention in real estate markets to encourage desired development projects

quantity premium in real property markets in this paper a theory of nonlinear pricing is tested using 1993 land market data in residential districts of the osaka metropolitan area it is shown that quantity premia prevail in real property markets i e larger lots are proportionately more expensive this is due to irreversibility in changing lot size and an oligopolistic market structure with nondecreasing marginal utility of lot size

stable trading structures in bilateral oligopolies abstract this paper analyzes the formation of trading groups in a bilateral market where agents trade according to a shapley shubik j polit econ 85 1977 937 968 trading mechanism the only strongly stable trading structure is the grand coalition where all agents trade on the same market other weakly stable trading structures exist and are characterized by an ordering property trading groups can be ranked by size and cannot contain very different numbers of traders of the two types journal of economic literatureclassification numbers d43 d51

fuel tourism in border regions the case of switzerland this paper explores the issue of fuel tourism in switzerland for the period 1985 1997 a panel data model for the border regions of switzerland italy france and germany is estimated the results show a significant impact of the gasoline price differential on demand suggesting that a decrease of 10 in the swiss gasoline price leads to an increase in demand in the border areas of nearly 17 5 it is shown that fuel tourism accounted for about 9 of overall gasoline sales in the three regions during the period 1985 1997 and that the recently proposed swiss co2 tax might given current conditions eliminate net fuel tourism

functional form and aggregate energy demand elasticities a nonparametric panel approach for 17 oecd countries this paper studies whether the commonly used linear parametric model for estimating aggregate energy demand is the correct functional specification for the data generating process parametric and n

a decomposition of the price and income elasticity of the consumer demand for gasoline the authors specify and estimate a model of the short run demand for gasoline which allows them to decompose a consumer s gasoline demand elasticities into miles driven and driving efficiency components their model is estimated using detailed household survey data which allows direct focus on the short run holding both the household s automobile stock and demographic profile fixed among the most interesting results are 1 the data allow interesting insights to be drawn into the interrelationship between these important variables and household behavior with respect to gasoline consumption miles driven and driving efficiency 2 the gasoline demand behavior of one car and multi car households differ significantly from each other evaluated at overall sample means one car households have higher in absolute value price elasticites for gasoline miles driven and fuel efficiency demand conversely multi car households have higher in absolute value total expenditure elasticities for each category 3 for both one car and multi car households roughly 75 of the estimated price elasticity and roughly 80 of the estimated total expenditure elasticity of gasoline demand stem from the miles driven component the estimated fuel efficiency elasticities though smaller than their standard errors indicate that households respond to changes in prices and total expenditure levels not only by changing the number of miles theymore drive but also by changing the efficiency with which they drive them 23 references 3 tables less

the sensitivity of consumption of oil products to price changes an econometric investigation abstract this paper presents a small econometric model of the supply and demand of motor spirit diesel fuel oil and other gas diesel oil by modelling at this level of disaggregation it is possible to identify the dynamic structure of each market and estimate own price and cross price elasticities

breakdown in multilateral negotiations abstract we analyze a complete information multilateral bargaining model in which a buyer is to purchase two complementary goods from two sellers binding cash offer contracts are used to govern transactions in contrast to preexisting literature we do not normalize the parties reservation utilities to zero we show that this assumption holds critical importance by demonstrating that a complete breakdown of negotiations may occur as the unique equilibrium outcome even if only two sellers are present

demand for gasoline in the gcc an application of pooling and testing procedures the structure of gasoline demand in the gcc countries was analysed the aim was to estimate price and income elasticities both for the short and long run it was found that gasoline demand is inelastic with respect to both price and income for both the short and long run when gcc countries were divided into two groups based on their pricing policies it was found that the group with the free market approach and higher reliance on market forces gave larger price elasticities and smaller income elasticities in both the short run and long run

an experimental study of the holdout problem in a multilateral bargaining game abstract when an economic exchange requires agreement by multiple independent parties the potential exists for an individual to strategically delay agreement in an attempt to capture a greater share of the surplus created by the exchange this holdout problem is a common feature of the land assembly literature because development frequently requires the assembly of multiple parcels of land we use experimental methods to examine holdout behavior in a laboratory bargaining game that involves multi person groups complementary exchanges and holdout externalities the results of six treatments that vary the bargaining institution number of bargaining periods and the cost of delay demonstrate that holdout is common across institutions and is on average a payoff improving strategy for responders both proposers and responders take a more aggressive initial bargaining stance in multi period bargaining treatments relative to single period treatments but take a less aggressive bargaining stance when delay is costly nearly all exchanges eventually occur in our multi period treatments leading to higher overall efficiency relative to the single period treatments both with and without delay costs

household demand for energy in the uk abstract many demand systems have recently been estimated which treat consumer expenditure on energy as one of a small number of similar expenditure groups this study formulates a simple demand system in which expenditures on individual fuels are also examined and into which the role of the stock of energy using appliances is integrated it goes on to adopt a particular functional form for consumer preferences and then fits the resultant econometric system to quarterly british data

modelling oecd industrial energy demand asymmetric price responses and energy saving technical change abstract the industrial sector embodies a multifaceted production process consequently modelling the derived demand for energy is a complex issue made all the more difficult by the need to capture the effect of technical progress of the capital stock this paper is an exercise in econometric modelling of industrial energy demand using panel data for 15 oecd countries over the period 1962 2003 exploring the issue of energy saving technical change and asymmetric price responses although difficult to determine precisely it is tentatively concluded that the preferred specification for oecd industrial energy demand incorporates asymmetric price responses but not exogenous energy saving technical change

elasticities science or fiction abstract apart from discrepancies in statistical data series the most frequent source of inconsistencies among elasticity estimates is the model specification and the interpretation of empirical results this paper investigates this issue and in particular highlights the misconception that elasticities can scientifically and uniquely be determined by econometric techniques however it is common knowledge that econometric methods constitute a very good tool for analysing the past thus the main message of this exercise is that in the absence of complete specification there are important trends in the elasticities themselves such trends are very crucial and need to be interpreted if elasticities are to be used for forecasting purposes

energy consumption and economic activity in industrialized economies a note abstract in industrialized countries the income elasticity of primary energy demand is not far off unity furthermore it can be argued that there is little use in distinguishing between short and long term income elasticities a long term income elasticity does not have a direct impact on energy demand and hence it is of doubtful use in energy demand projections via an aggregate oecd model it was estimated that the short term impact of prices on primary energy demand is about 0 15 while the long term impact is 0 43 but increasing over time

how do landowners price their lands during land expropriation and the motives behind it an explanation from a wta wtp experiment in central beijing compensation paid to property owners for land expropriation is always a controversial topic partly due to the difficulty in revealing households true valuation of their housing this paper estimates and discusses the widely observed willingness to accept willingness to pay wta wtp gap for surveyed residents of their own houses during land expropriation by testing several hypotheses interpreting the wta wtp disparity from previous studies the paper tries to establish the incentive for households decision making the paper employs a contingent valuation method with data from 315 household interviews in central beijing china the paper reports an average wta wtp ratio of 3 74 and reaches the conclusion that in our case the high compensation required by property owners largely derives from opportunistic pricing behaviour rather than sentimental attachment to the dwellings that is unobservable in the market price and that the wta of the residents is intentionally overpriced

strategic complements and substitutes in bilateral oligopolies this note analyzes the effect of product complementarity in a bilateral oligopoly we show that offers of traders on the two sides of the market are strategic complements substitutes if and only if the two goods are substitutes complements the outcome of the bilateral oligopoly game converges monotonically to the competitive equilibrium as the elasticity of substitution between the goods decreases to minus infinite

the impact of vat introduction on uk residential energy demand an investigation using the cointegration approach abstract over a two year period which started in april 1994 the real price of energy to uk households was expected to rise by 17 5 as a result of value added tax vat introduction the regressive nature of the tax forced the government to limit vat on residential fuel to 8 using a cointegration approach to take account of the non stationarity fuel consumption time series this paper estimates real energy and fuel specific price and income elasticities for the period 1974 1 1994 1 they suggest that natural gas has a positive real energy price elasticity indicating that as real price of energy rises households scrap inefficient heaters and invest in more efficient ones principally natural gas these estimates enable projections to be made of the impact of the introduction of vat and imply a rise in natural gas consumption as a result of the additional vat although at the expense of other less efficient fuels overall residential energy consumption however is unlikely to fall significantly from the tax suggesting that it is an inappropriate way of achieving environmental objectives

on the land assembly problem abstract we consider a segment of the land market where the entire available land stock is needed for the realization of some indivisible development project the stock is shared by several landholders who either collude or negotiate independently with the developer over the prices of their lots investigating the price setting behavior of the landowners and the optimal strategy of the developer we show that landowners set more moderate prices under collusion than when acting independently in the latter case the individual asking price falls with the size of the land share and the total price increases with the number of landowners as regards the optimal strategy we find that the developer will in general not offer the lowest price he expects to be accepted by the landowners

elasticities of electricity demand in india abstract the paper examines econometric relationship between electricity consumption and variables like income price of electricity and diesel used in for captive power generation to meet the shortages and reliability of power supply from utilities in five major consumer categories in india these categories are residential commercial agriculture small and medium industries and large industries income and price elasticities of electricity consumption are estimated at the national level for these consumers by pooling data across 19 states spread over 9 years 1985 86 1993 94 the results show that electricity consumption in commercial and large industrial sectors are income elastic 1 while residential agricultural and small and medium industries are income inelastic

the demand for energy in the uk a general equilibrium analysis abstract previous research into the demand for energy has treated economic activity as an explanatory variable however economic theory suggests that economic activity is not independent of energy prices and energy demand we explore the two way causality between energy demand and economic activity in the context of a macroeconometric model of the uk economy inter alia this study suggests that the demand for energy is more price elastic in general equilibrium than it is under the more conventional assumptions of partial equilibrium

an aggregate petroleum consumption model abstract this paper presents an aggregative model of us consumption of petroleum and products of a type which might potentially be used to derive short term forecasts of us petroleum consumption and imports the model attempts to separate income and weather related changes from those induced by changes in relative prices with emphasis on the dynamic path of consumption responses to price changes estimation results suggest that there are still significant price effects six years after a change in the relative price of petroleum

accounting for technical progress in aggregate energy demand abstract researchers have not reached a consensus on how to account for technical progress when modeling aggregate energy demand some include a time trend in a dynamic model while others omit the trend in a model that disallows for long run income effects we show that the latter approach can be directly tested as a nested case of the former so that model selection need not be made a priori solely on theoretical grounds using annual data over 1960 1990 we find that long run income effects are not significant however including a time trend improves the model s fit while rendering much more credible long run price elasticities

road transport energy demand in australia a cointegration approach abstract a cointegration framework is used to examine the short run and long run characteristics of energy demand in the australian road transport sector a lagged endogenous equation based on a partial adjustment process is proposed and estimated results indicate that energy demand output and real energy prices are integrated of order 1 and cointegrated the long run output and price elasticities of energy demand are estimated to be 0 52 and 0 12 respectively causality tests ervealed a bidirectional causality path between output and energy demand and a unidirectional path from energy consumption to prices no other causality paths between output prices and energy demand are detected the short run output elasticity of energy demand is estimated to be 0 25 based on an error correction model the short run price elasticity is found to be insignificant the inertia parameter is 0 48 corresponding to 95 of the demand adjustment occurring after five periods the results are compared with previous findings and the variations are partially attributed to the structural changes in the road transport sector in the 1980s some of which are discussed

a meta analysis of the price elasticity of gasoline demand a sur approach abstract automobile gasoline demand can be expressed as a multiplicative function of fuel efficiency mileage per car and car ownership this implies a linear relationship between the price elasticity of total fuel demand and the price elasticities of fuel efficiency mileage per car and car ownership in this meta analytical study we aim to investigate and explain the variation in empirical estimates of the price elasticity of gasoline demand a methodological novelty is that we use the linear relationship between the elasticities to develop a meta analytical estimation approach based on a seemingly unrelated regression sur model with cross equation restrictions this approach enables us to combine observations of different elasticities and thus increase our sample size furthermore it allows for a more detailed interpretation of our meta regression results the empirical results of the study demonstrate that the sur approach leads to more precise results i e lower standard errors than a standard meta analytical approach we find that with mean short run and long run price elasticities of 0 34 and 0 84 respectively the demand for gasoline is not very price sensitive both in the short and the long run the impact of a change in the gasoline price on demand is mainly driven by responses in fuel efficiency and mileage per car and to a slightly lesser degree by changes in car ownership furthermore we find that study characteristics relating to the geographic area studied the year of the study the type of data used the time horizon and the functional specification of the demand equation have a significant impact on the estimated value of the price elasticity of gasoline demand

metaanalisis de las elasticidades ingreso y precio de la demanda de energia algunas implicaciones de politica publica para america latina the aim of this paper is to analyze the variation in empirical estimates of the income and price elasticities of energy demand the evidence presented through a meta analysis allows identification of the weighted average of the income and price elasticities shows that the estimates are very heterogeneous that there is publication bias and that factors such as region energy sector among others affect its volatility the evidence also indicates that income elasticity in latin america is greater than in the oecd countries and that the price elasticity of energy demand is lower in latin america than in the oecd countries therefore continued economic growth in latin america will be accompanied by a growth in energy demand moreover the establishment of a tax in latin america under the current elasticities is less effective and will be insufficient to control the increase in energy consumption

transparency complementarity and holdout this paper characterizes the conditions under which holdout i e bargaining inefficiency may or may not be significant in a two sided one buyer many seller model with complementarity we address this problem in a very general setup with a bargaining protocol that is symmetric and allows for both publicly observable as well as secret offers and a technology that allows for variable degrees of complementarity the central insight is that the transparency of the bargaining protocol formalized by whether offers are publicly observable or secret as well as the extent of complementarity play a critical role in generating efficiency even with perfect complementarity holdout seems to be largely resolved whenever the bargaining protocol is public but not if it is secret further irrespective of the bargaining protocol holdout is resolved if the marginal contribution of the last seller is not too large

how sensitive to time period sampling is the asymmetric price response specification in energy demand modelling abstract the purpose of this paper is to investigate the criticism that energy demand estimates based on a specific price decomposition are sensitive to the chosen time period used for the estimation to analyse this in a systematic way different time series sample periods are constructed from annual data for 17 oecd countries covering the overall period 1960 to 2008 the specific price decomposition under consideration often used to estimate asymmetric price response models of energy demand separates the impact of prices above the previous maximum of a price recovery below the previous maximum and of a price cut therefore the analysis does not just involve using different time periods instead for each time period investigated a new dataset is constructed and for each dataset the price variable is decomposed in this way an energy demand relationship allowing for asymmetric price responses is therefore estimated for each different sample period and the results suggest that recalculation of the decomposed price variables for each different period does affect the stability of the estimated energy demand responses in contrast a similarly estimated energy demand relationship with symmetric price responses for each different sample period is found to have less instability

tests for structural change in us oil consumption 1967 1982 abstract the purpose of this paper is to test us oil consumption for structural change over the period 1967 1982 a frequently used functional form is posited for total petroleum consumption as well as for gasoline distillate and residual fuel tests for abrupt change chow and gradual or conservation like change durbin brown evans and farley hinnich mcguire are employed at special break points 1973 embargo 1979 iranian crisis 1980 recession to check for abrupt changes and across years in general to detect gradual shifts both abrupt and gradual changes are found although the last five years may be the beginning of a new non changing period

bargaining behavior and the tragedy of the anticommons abstract to date most experimental studies of the tragedy of the anticommons treat individuals preferences as common knowledge here we conduct experiments in which values are private information we vary the bargaining institution the buyer s signaled willingness to pay and the fraction of sellers whose inputs must be assembled in our experiments simultaneous bargaining gives the buyer a better tradeoff between the total price paid and the risk of failure than sequential bargaining when all sellers inputs are necessary when two thirds are necessary assembly failure virtually disappears but simultaneous bargaining still generates lower prices for the buyer

gasoline demand the case of saudi arabia this paper specifies a partial adjustment model to estimate the demand for gasoline in saudi arabia for the period 1970 1985 it is found that the demand for gasoline is inelastic with respect to price in the short and long run as compared to other countries the kingdom s gasoline demand elasticities more closely resemble those of industrial countries

demand elasticities in oecd dynamical aspects abstract four models with different lag structures are used to express final energy demand in oecd from 1960 1982 as a function of real gdp and average energy price the income and long run price elasticities are not significantly dependent on the model specification but the koyck lag scheme estimated in its distributed lag form is found to give the most satisfactory results the statistical properties of the data together with evidence of trends in the elasticities both suggest that the period of falling real prices prior to 1971 is not comparable to the present period for the period after 1971 an income elsticity of 1 02 and a long run price elasticity of 0 37 are obtained

a determination of bid rents through bidding procedures abstract rent profiles in land markets with finitely many participants are derived under two bidding procedures free unit size bidding and single unit size bidding free unit size bidding is shown to be basically equivalent to an english auction whereas the rent determination problem under single unit size bidding reduces to a mathematical programming problem an application of the latter case is provided in which a density model of land use is shown to be a good approximation of appropriately chosen discrete models

energy consumption and economic activity in industrialized countries the dynamic aggregate time series relationship abstract most econometric studies suggest that the income elasticity of demand for energy is approximately unity for the developed market economies it is shown that over the period 1950 1978 the long run income elasticity is substantially higher than unity in terms of a ces energy demand function this result reflects the application of a generalized dynamic estimation methodology where serial correlation is regarded as a diagnostic guide to distributed lag fitting price elasticities are also estimated but these are in line with conventional estimates

energy elasticities under divisia and btu aggregation abstract this paper considers two methods of energy aggregation divisia and btu a dynamic demand model is used to study the response of energy use to price and income changes under these two aggregation schemes while the short run responses of energy use are found to be similar the long run response is greater under divisia than under btu aggregation especially in periods of marked changes in energy prices

economic modelling of energy services rectifying misspecified energy demand functions abstract although it is well known that energy demand is derived since energy is required not for its own sake but for the energy services it produces such as heating lighting and motive power energy demand models both theoretical and empirical often fail to take account of this feature in this paper we highlight the misspecification that results from ignoring this aspect and its empirical implications biased estimates of price elasticities and other measures and provide a relatively simple and empirically practicable way to rectify it which has a strong theoretical grounding to do so we develop an explicit model of consumer behaviour in which utility derives from consumption of energy services rather than from the energy sources that are used to produce them as we discuss this approach opens up the possibility of examining many aspects of energy demand in a theoretically sound way that have not previously been considered on a widespread basis although some existing empirical work could be interpreted as being consistent with this type of specification while this formulation yields demand equations for energy services rather than for energy or particular energy sources these are shown to be readily converted without added complexity into the standard type of energy demand equation s that is are typically estimated the additional terms that the resulting energy demand equations include compared to those that are typically estimated highlight the misspecification that is implicit when typical energy demand equations are estimated a simple solution for dealing with an apparent drawback of this formulation for empirical purposes namely that information is required on typically unobserved energy efficiency indicates how energy efficiency can be captured in the model such as by including exogenous trends and or including its possible dependence on past energy prices the approach is illustrated using an empirical example that involves estimation of an aggregate energy demand function for the uk with data over the period 1960 2011

the demand for electricity in israel quarterly data for israel are used to compare and contrast three dynamic econometric methodologies for estimating the demand for electricity by households and industrial companies these are the dynamic regression model and two approaches to cointegration ols and maximum likelihood since we find evidence of seasonal unit roots in the data we also test for seasonal cointegration we find that the scale elasticities are similar in all three approaches but the ols price elasticities are considerably lower moreover ols suggests non cointegration the paper concludes by stochastically simulating the drms to calculate upside risk in electricity demand

the holdout problem and urban sprawl experimental evidence abstract conventional wisdom as well as economic theory suggests it is more costly to reassemble fragmented land due to transactions costs and strategic bargaining costs both costs are expected to increase with the number of sellers inefficient allocation of land resources may result including property entropy parisi 2002 urban sprawl miceli and sirmans 2007 and deteriorating inner cities given the difficulty of observing actual values attached by buyers and sellers to land little empirical evidence exists to support the conventional wisdom and theoretical work we use experimental methods to examine transactions costs and strategic bargaining costs in a land assembly market game with one buyer 1 4 sellers and complementary exchanges the buyer s final earnings vary inversely with the number of sellers ceteris paribus indicating an incentive to purchase consolidated land delay costs reduce holdout but result in lower payoffs for both buyers and sellers competition between sellers reduces holdout and the buyer s total purchase price
