foreign exchange shocks and gasoline consumption abstract in an open economy the foreign exchange rate fer influences incentives for the cross border shopping of gasoline as well as the opportunity cost of using vehicles and the relative attractiveness of home versus foreign travel using monthly regional level data of gasoline consumption in iran we estimate the impact of exchange rate shocks both in level and volatility on gasoline demand we find that positive exchange rate shocks have a negative impact on total gasoline consumption as well as on vehicle users demand in both short run and long run furthermore we find that in the periods that fer is less volatile the responsiveness of gasoline demand to a change in fer is more pronounced

gasoline demand in europe new insights abstract this study utilizes a panel data set from 14 european countries over the period 1990 2004 to estimate a dynamic model specification for gasoline demand previous studies estimating gasoline consumption per total passenger cars ignore the recent increase in the number of diesel cars in most european countries leading to biased elasticity estimates we apply several common dynamic panel estimators to our small sample results show that specifications neglecting the share of diesel cars overestimate short run income price and car ownership elasticities it appears that the results of standard pooled estimators are more reliable than common iv gmm estimators applied to our small data set

consumer research with big data applications from the food demand survey foods in three separate studies based on data from the food demand survey foods which has been conducted monthly for over three years this paper explores heterogeneity in preference across consumers in traditional demand systems heterogeneity in preferences over time in choice experiments and the tail of the distribution for a particular food consumption pattern vegetarianism results show that elasticities of demand for food at home and food away from home vary widely across different groups of consumers defined by a priori cluster analysis based on demographic and attitudinal variables results from a choice experiment are found to depend on when the experiment was conducted and on the market prices prevailing at the time of the survey given the large sample of consumers observed over time there is sufficient data to demographically characterize a small portion of the population vegetarians using traditional logit models and a machine learning method a classifications tree

perceived price in residential water demand evidence from a natural experiment abstract under complicated billing structures the price to which consumers respond remains inconclusive in this paper i exploit a quasi experiment to estimate a causal effect of price for residential water customers during the introduction of increasing block rates for a north carolina utility perceived price is identified through a billing anomaly in which changes in marginal and average prices move in opposite directions empirical results contribute evidence that residential water customers respond to average price average price elasticity estimates vary from 0 43 to 1 14 across the distribution of consumption in triple difference models with an estimate of 0 31 in the tightest bandwidth of regression discontinuity specifications

ethanol demand under the flex fuel technology regime in brazil abstract this paper analyzes the characteristics of ethanol demand in the context of fuel mix diversification in brazil currently ethanol is the most important gasoline additive and alternative fuel consumed in brazil and is responsible there for profound changes in the dynamics of fuel consumption the diffusion of flex fuel vehicles in brazil symbolizes a new stage of ethanol expansion and is a central component of the increasing demand for fuel accordingly we evaluate ethanol demand in brazil following the introduction of flex fuel vehicles using a cointegration approach and autoregressive distributed lag bounds tests over the period 2003 2010 the evidences confirm that during the last decade ethanol has strengthened its position as both an independent fuel and a substitute for gasoline there is also evidence that growth in the brazilian automobile fleet based on flex fuel technology is a major driving factor of long run ethanol demand further the dynamics of gasohol mandatory blend of gasoline and ethanol and ethanol prices operate in a symmetric manner over ethanol demand thereby evidencing the increasing substitutability between these alternative fuels

who pays and who gains from fuel policies in brazil abstract brazil has pursued a mix of policy interventions in the fuel sector to achieve multiple objectives of economic and social development promoting biofuels and reducing dependence on oil we develop an economic framework to provide insight on the fuel policy choices in brazil and to analyze the trade offs they have engendered in the fuel and sugar sectors we also examine their distributional impacts on producers and consumers in the sugar oil and biofuel sectors and on government revenues additionally we undertake a normative analysis for the purpose of comparing the welfare and environmental impacts of existing policies with those justified by the goal of maximizing social welfare and addressing market failure the ex post analysis of the outcomes for different stakeholders in the fuel and sugar sectors provides insights on the likely political economic factors guiding policy choices we find that the status quo policies are likely to have been motivated by the objectives of increasing oil exports raising government revenue and promoting rural development through the sugarcane sector and have had a significant adverse effect on fuel and sugar consumers aggregate social welfare and greenhouse gas emissions in brazil

an empirical analysis of petroleum demand for indonesia an application of the cointegration approach this paper uses selection criteria from various models in a bounds testing approach to cointegration to estimate the price and income elasticities of demand for total petroleum products gasoline and diesel and gasoline share in total products in indonesia the results suggest that both total products and gasoline share estimates are more responsive to changes in income than changes in the real price of petroleum products these results have important policy implications as they suggest that policy makers may need to use market based pricing policies and other policies such as public enlightenment in addition to regulations like minimum energy efficiency standards to promote efficiency and conservation and curb the rising consumption of petroleum products in indonesia

the demand for gasoline abstract sufficient time must be allowed to elapse to assess fully the response of gasoline demand to price changes hitherto empirical work on the subject has generally not examined the period beyond 1975 moreover the extant time series studies concentrate almost exclusively on the usa this study extends both the observation period and the country coverage a vehicle stock adjustment model is estimated via its reduced form without explicit consideration of the vehicle stock itself however the estimation procedure incorporates the structure by way of constraints on the parameters cross section analysis offers additional evidence concerning the truly long run price elasticity the results suggest that there is no need to resort to elaborate models to explain adequately gasoline demand gasoline demand exhibits a long run price elasticity near unity with time lags exceeding six years while there is tentative evidence that the duration of these lags is not fixed

analyzing light fuel demand elasticities in brazil using cointegration techniques abstract this study is intended to assess the sensitivity of demand for light fuels in brazil to changes in prices and income considering the unique characteristics of the brazilian fleet the lack of convergence across studies available for the domestic market and its importance in discussions on climate change and national security among others for this purpose the short and long term price and income elasticities of light fuel demand were estimated using cointegration techniques based on an empirical model that incorporates the unique features of the internal market despite the characteristics of the brazilian fleet the results showed that the elasticities found for the national market are similar to those seen in other countries the conceptual framework and empirical analysis that were used also allowed for a better understanding of the differences between the results of studies on demand for gasoline ethanol or natural gas in brazil and those found in the international literature providing key players in the sector with crucial information for designing public policies and business strategies

growth and defense pooled estimates for the nato alliance 1951 1988 in two provocative and influential contributions emile benoit 4 5 uncovered a net positive association between defense spending and economic growth for 44 less developed countries ldcs during the 1950 65 period apparently a larger defense burden as measured by the share of national income devoted to defense may have promoted growth for these countries this finding was controversial and generated an extensive literature that either found fault with benoit s methodology or else investigated the relationship between growth and defense with alternative methodologies one such methodology relied on an aggregate production function to derive an equation for the sources of growth owing to technological change labor growth investment productivity differences among sectors and externalities this supply side approach was associated with feder 13 and ram 22 when a feder ram model was used researchers typically discovered either a small positive effect or else no impact of defense on growth except for alexander 1 the feder ram approach has been applied to large cross sections of ldcs to cross sections of ldcs and developed countries or to individual countries over time the purpose of this paper is fivefold first we extend the three sector feder ram model to allow for the influence of defense spillin externalities as the defense expenditures of a nation s allies affect the nation s own defense and civilian sectors in either a positive or negative fashion spillin externalities can stem from input complementarity or substitutability procurement practices joint ventures or operational considerations second we check the data for unit roots and when appropriate cointegration these tests help us to avoid a dynamic misspecification third we estimate a three sector feder ram growth equation for each of ten nato allies for the 1951

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

effect of government quality grade labels on consumer demand for pork chops in the short and long run abstract despite ample evidence of pork quality variability at present there are few signals that would incentivize growers to produce higher quality pork using split sample choice experiment data from a nationwide online survey of u s pork chop eaters this research determines changes in pork chop demand in response to a potential change in u s government policy that would introduce a new pork quality grading system based on color scores our simulations include novel short run projections in which the conditional and latent class logit models are inverted to yield inverse demand curves the inverse demand curves are used to calculate equilibrium prices and pork revenue given a fixed supply of different pork qualities we supplement these calculations with a more traditional long run analysis in which prices are fixed and quantities of different qualities adjust compared to the status quo control of no quality grades we find that two grading systems based on alternative nomenclatures select choice prime vs good better best both have the potential to increase pork chop sales and revenue to the pork industry however we also find that if only the highest quality is labeled revenue could fall as the increase in demand for the higher quality is offset by the fall in demand for the lower qualities results also highlight important heterogeneity in consumer preferences and although sensory studies strongly suggest redder pork chops are more highly preferred there remains a non trivial share of consumers who prefer whiter pork even after quality grade labeling overall this study offers several insights that can help inform labeling and quality grading policies

what happens when food marketers require restrictive farming practices the dimensions that define a food product have expanded rapidly to include characteristics of the production process marketing arrangements and implications that production and consumption of the product have for the environment some market intermediaries have responded by requiring that their suppliers abide by restrictive production practices we examine the economic effects of such restrictions and apply this analysis to limitations on the use of antibiotics in u s pork production results from conceptual and simulation analyses show that in the absence of demand growth less pork is sold due to higher costs in the restricted segment and both pork consumers on average and producers are harmed demand growth of between 6 11 from adding new consumers who will consume the restricted antibiotic free product but not the conventional product is needed to return consumer surplus to the level in the base case and between 2 4 demand growth was required to return producer surplus to base when restricted and conventional products are modeled using a vertical differentiation framework results depend importantly on the ease with which consumers can switch to a seller who offers their desired product type significant distributional impacts among consumers are present when switching costs are prohibitive

information health risk beliefs and the demand for fats and oils mean and variance measures of health information about cholesterol and saturated fat are included in a demand system for fats and oils a bayesian model of health risk belief and consumer awareness surveys are the basis for computing these measures the empirical demand model shows that health information has resulted in significant increases in consumption for corn cottonseed and soybean oils and decreased consumption for butter and lard the predicted demand effects based on the bayesian information model are more reasonable than predictions from using either a time trend or a simple cumulative cholesterol information index copyright 1995 by mit press

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

demand of automotive fuels in brazil underlying energy demand trend and asymmetric price response abstract this paper analyzes the role of asymmetric price response apr and underlying energy demand trend uedt in the brazilian automotive fuel demand from june 2001 to december 2016 the demand functions of automotive gasoline ethanol and compressed natural gas cng were estimated by employing the autoregressive distributed lag ardl model and harvey s structural time series model stsm the importance of considering a more flexible approach incorporating both uedt and apr was confirmed by the data we identified that consumer response to changes in price is not linear the model also inferred a high substitutability between gasoline and ethanol both in the short and the long term demand for ethanol is more price elastic than demand for gasoline empirical analysis suggests that the decision to refuel a vehicle with cng is not influenced by price variations in ethanol which indicates that competition only occurs between cng and gasoline therefore the inclusion of uedt and apr provides more precise information on the effect of price and income changes on automotive fuel demand such information is relevant for establishing public policies as refinery expansion plannning and co2 emission mitigation

measuring welfare effects of product contamination with consumer uncertainty abstract a methodology is developed for measuring consumer welfare loss from market demand due to contamination when information is imperfect comparison of behavior before and after awareness permits calculation of the cost of ignorance which occurs when news of contamination is withheld or undiscovered for a time as well as when excessive reporting and exaggeration cause overreaction avoidance costs are also calculated for consumers who consume less than they would with perfect information due to risk aversion the methodology is applied to analyzing the heptachlor crisis which reduced milk consumption in hawaii by over 80

watching the fuel gauge an international model of automobile fuel economy utilizing a new international data set and a non linear maximum likelihood model this study analyses the role of fuel prices income government taxation and technological change in influencing the consumers choice of fuel economy the results of this study imply that the consumers choice of automobile fuel efficiency is less sensitive to fuel prices and income than previously believed this inelasticity of the demand for fuel economy is important to consider when evaluating the potential impact of higher fuel economy mandates or higher fuel taxes this study also found that fuel price differentials and differences in the level of automobile purchase and registration taxes account for most of the difference in automobile fuel economy across countries

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

are choice experiments incentive compatible a test with quality differentiated beef steaks this study compares hypothetical and nonhypothetical responses to choice experiment questions we test for hypothetical bias in a choice experiment involving beef ribeye steaks with differing quality attributes in general hypothetical responses predicted higher probabilities of purchasing beef steaks than nonhypothetical responses thus hypothetical choices overestimate total willingness to pay for beef steaks however marginal willingness to pay for a change in steak quality is in general not statistically different across hypothetical and actual payment settings

a discrete continuous choice approach to residential water demand under block rate pricing reply waldman is quite correct in noting that the microeconomic theory of block rate pricing in hewitt and hanemann hh 1995 is given for the general case of a k block rate structure whereas the econometric theory is largely confined to the case of exactly two blocks the extension in waldman to the more general case of k blocks is correct although the extension itself could be even more general if it addressed the nonnegativity of demand as is demonstrated below that no apparent attention was paid to the nonnegativity of demand in hh may be attributed to the fact that the need to do so was negated by a fortuitous assumption in the earlier work although that assumption that the errors are multiplicative and lognormally distributed was only maintained and not tested in hh i now estimate two models with the more common assumptions of linear demand and additive and normally distributed errors both with and without a modification for

gasoline demand revisited an international meta analysis of elasticities meta analysis is used to determine if there are factors that systematically affect price and income elasticity estimates in studies of gasoline demand four econometric models are estimated using long run and short run price and income elasticity estimates from previous studies as the dependent variables explanatory variables include functional form lag structure time span national setting estimation technique and other features of the model structure elasticity estimates are found to be sensitive to the inclusion or exclusion of some measure of vehicle ownership static models appear to overestimate short run elasticities underestimate long run price elasticities but pick up the full long run income responsiveness there is variation in the elasticity of demand across countries especially in the short run and gasoline demand appears to be getting more price elastic and less income elastic over time

the car park diffusion models revisited abstract growth in the car park in two countries the uk and japan is studied with the help of a diffusion model of car ownership the model interprets the complicated dynamics of the car park in particular the transitions between different stages of growth in terms of three effects product diffusion income dispersion and income growth from the insights gained in the analysis a specific parameterized non linear lifecycle model of car ownership is constructed which is of use in the investigation of a range of issues including the impact of social trends and green policies on car ownership

fuel demand in brazil in a dynamic panel data approach abstract the purpose of this paper is to evaluate the sensitivity of fuel consumers regarding price and income taking recent changes in the brazilian fuel market into account in this market new market rules energy policy towards fuel diversification and introduction of flex fuel engines have determined fuel competition among gasoline ethanol and compressed natural gas using a dynamic panel data model demand equations for these three fuels are econometrically estimated to obtain consumer adjustment coefficients price cross price and income elasticities in the short and long run in addition the effect of the introduction of flex fuel engines in the market and the rationality of consumers towards efficiency constraints of the engines were tested apart from considerable competition results show that the dynamics of the brazilian fuel market revolves around ethanol instead of gasoline while demands for gasoline and natural gas are inelastic to price demand for ethanol is elastic in brazil furthermore after the introduction of the flex fuel technology the sensitivity of consumers to fuel prices changed and ethanol consumers take efficiency constrains into account when ethanol prices reach the threshold of 70 of gasoline prices

how do urban households in china respond to increasing block pricing in electricity evidence from a fuzzy regression discontinuity approach abstract china is the largest electricity consumption country after it has passed the united states in 2011 residential electricity consumption in china grew by 381 35 12 85 per annum between 2000 and 2013 in order to deal with rapid growth in residential electricity consumption an increasing block pricing policy was introduced for residential electricity consumers in china on july 1st 2012 using difference in differences models with a fuzzy regression discontinuity design we estimate a causal effect of price on electricity consumption for urban households during the introduction of increasing block pricing policy in guangdong province of china we find that consumers do not respond to a smaller approximately 8 increase in marginal price however consumers do respond to a larger increase in marginal price an approximately 40 increase in marginal price induces an approximately 35 decrease in electricity use 284 kw h per month our results suggest that although the increasing block pricing could affect the behavior of households with higher electricity use there is only a limit potential to overall energy conservation

modeling energy demand some emerging issues abstract the proliferation of papers on energy demand modeling has offered different dimensions both in terms of methodology and estimation while this development has strengthened our understanding of the subject it may render the identification of gaps in the literature arduous for future research thus this study sets out to document some emerging issues that seem to have engendered new directions on energy demand modeling ranging from asymmetric price responses time varying demand parameters triangulation analyses to seasonal and climate change effects it is hoped that access to this review complemented with the previous ones will facilitate the comprehension of the extant literature as well as areas of future research in energy demand modeling

estimating energy and oil demand functions a study of thirteen developing countries abstract in this paper we attempt to identify some of the factors that have determined the level and pattern of energy demand in developing countries during the 1970s and early 1980s aggregate oil and energy demanding functions are constructed for a selection of oil importing countries and oil exporting countries the results show a strong link between income and aggregate energy demand conversely the price elasticity of energy demand is low both in the short run and the long run oil demand behaviour is more complex oil products can be rationed or domestic energy production can affect oil demand nonetheless the income elasticity remains close to one in most countries and is well above one for some

consumer preferences for fresh food items with multiple quality attributes evidence from an experimental auction of pork chops this study illustrates an application of experimental auction methods using both experimental economics and experimental design to evaluate consumer perceptions and willingness to pay wtp for fresh pork chops we test and reject hypotheses that a market prices and consumers wtp are unaffected by the level of attributes embodied in the pork chops b appearance based on photographs or actual product and actual taste are equally good sources of consumer information and c consumers are consistent in their preferences for fresh pork attributes a major conclusion is that predicting consumer demand for fresh pork or any fresh food based on appearance without tasting is unproductive

household water demand seasonal elasticities a stone geary model under an increasing block rate structure using household level panel data from tucson arizona and a unique set of highly disaggregated control variables we estimate residential demand for water via a stone geary specification the stone geary functional form allows price elasticity of demand to vary with quantity consumed price and income and enables estimation of a threshold level of consumption below which demand is considered perfectly price inelastic an encompassing test of consumer price response reveals evidence favoring a lagged average price specification rather than one using lagged marginal price the estimated model also finds substantial seasonal variation in price elasticity and declining consumer price responsiveness

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

gasoline prices gasoline consumption and new vehicle fuel economy evidence for a large sample of countries abstract countries differ considerably in terms of the price drivers pay for gasoline this paper uses data for 132 countries for the period 1995 2008 to investigate the implications of these differences for the consumption of gasoline for road transport to address the potential for simultaneity bias we use both a country s oil reserves and the international crude oil price as instruments for a country s average gasoline pump price we obtain estimates of the long run price elasticity of gasoline demand of between 0 2 and 0 5 using newly available data for a sub sample of 43 countries we also find that higher gasoline prices induce consumers to substitute to vehicles that are more fuel efficient with an estimated elasticity of 0 2 despite the small size of our elasticity estimates there is considerable scope for low price countries to achieve gasoline savings and vehicle fuel economy improvements via reducing gasoline subsidies and or increasing gasoline taxes

an empirical analysis of gasoline demand in denmark using cointegration techniques abstract danish time series data covering the period 1948 1991 are used in order to estimate short run and long run elasticities in gasoline demand a cointegration test for a stable long run relationship between the variables in the model proves to be positive showing a smaller value of the long run price elasticity than often quoted in empirical studies of gasoline demand finally an error correction model is estimated

gasoline consumption and the stock of motor vehicles an empirical analysis for the swiss economy abstract the demand for gasoline and the stock of cars is empirically explained for the swiss economy by applying statistical methods from modern time series analysis to annual data over the period 1962 1985 the short run price and income elasticities of gasoline consumption are 0 3 to 0 45 and 0 7 the price elasticity became substantially higher after the first opec shock in 1973 pollution control measures introduced in 1982 negatively affected the stock of cars longer run effects operating over changes in the size of the stock and the fuel efficiency of cars are stretched out over several years as shown by a variety of simulation experiments

empirical assessment of the determinants of road energy demand in greece this paper attempts to cast light on the determinants of road energy demand in greece for this purpose we used cointegration techniques and vector autoregression var analysis in order to capture short run and long run dynamics for gasoline and diesel demand respectively from the empirical analysis that covers the period 1978 2003 we find that in the long run gasoline energy demand appears to be price and income inelastic while diesel demand appears to be price inelastic and income elastic we also found that the absence of close substitutes in the road sector denotes the low level of energy switching in greece

short and long term equilibria relationships between first and third generation dynamic factor demand models abstract first generation dynamic models of input demands are theoretically inferior to third generation models yet their simplicity makes them attractive for estimation purposes moreover first generation models can be shown to be generically related to third generation models and under certain assumptions input demand expressions in a third generation model collapse to those of the first generation seemingly offering a short cut for estimation however empirical comparisons suggest that first generation specifications do not afford a reasonable approximation to input functions embedded in more complex third generation models furthermore the reduced form coefficients do not permit identification of third generation model structures

long run gasoline demand for passenger cars the role of income distribution it is commonly agreed that the level of income and prices are crucial determinants of the consumption of motor gasoline the respective long run price and income elasticities are regularly calculated using cross sectional models despite the acknowledgement of the role of income distribution it plays no role in intercountry cross sectional models this is due to a lack of appropriate data this paper shows that the omission of distributional characteristics provides misleading elasticities using available distributional measures this paper is referring to an income threshold which is crucial to the acquisition of an automobile it is shown that on the one hand in poor countries an unequal income distribution is needed to enable at least some people to buy automobiles on the other hand in wealthy countries an unequal income distribution would exclude some people from acquiring automobiles hence depending on the income level inequality has a diverging impact on the ability to buy durable goods the second part of this paper develops a pooled 90 country model to examine this approach empirically it could be shown that distribution variables are highly significant to explain the demand for automobiles and motor gasoline moreover the consideration of the distribution of income leads to a considerable decrease in income elasticity values this is mainly due to the positive correlation between income level and income equality within the sample

gasoline and diesel demand in the eu implications for the 2030 emission goal abstract methodologically consistent demand estimates are necessary to analyze and forecast the effect of a common fuel policy across the eu 28 this study estimates short run and long run price and income elasticities for gasoline and diesel demands using the ardl bounds approach that also tests the existence of a long run relationship using data from 1978 to 2013 the results show that elasticity estimates between the eu 28 countries vary and the estimated long run elasticities are higher than their short run counterparts which is in line with expectations based on the existing literature the short run and long run income elasticities of gasoline and diesel demand are found to be more elastic than their price equivalents implying that if a charge on fuel is designed to decrease emissions by increasing the price the charge needs to rise at a higher rate than income an analysis of the eu s 2030 emission and fuel consumption reduction targets using the estimated long run elasticities shows that with the current tax scheme it cannot be guaranteed that emission targets will be achieved and thus a more stringent fuel tax policy is essential

reconsidering the economics of demand analysis with kinked budget constraints this paper has two objectives first we identify a problem with the ability of the discrete continuous choice framework and conditional demand functions to fully describe consumer preferences in the presence of kinked budget constraints second we propose and illustrate an alternative preference based method for estimating consumer responses to price changes under these conditions this framework recognizes that commitments to commodities such as pools or outdoor landscaping influence how water consumption responds to price changes as part of the long run consumption adjustments with microdata on household choices this approach could be used to design increasing block rate structures that recognize the differences in water consumption responses with these commitments

household adjustment to gasoline price change an analysis using 9 years of us survey data this paper examines the dynamics and composition of household adjustment to changes in the real price of gasoline using a panel of us households by decomposing the demand for gasoline into the demand for vehicle miles traveled and the demand for household composite miles per gallon we are able to add rich detail to the description of how households respond to gasoline price changes while obtaining total price elasticity estimates well within the range found in the literature we find that consumers initially respond to a price rise with a much larger decrease in consumption than would be indicated by the total elasticity in addition households respond to price changes by adjusting vehicle miles traveled more than composite miles per gallon in the year after a price change

the demand for transport fuels in turkey abstract in this paper we estimate the demand for transport fuels in turkey specifically using four different models namely a partial adjustment model a distributed lag model an autoregressive distributed lag model and an error correction model we estimate gasoline and diesel demand functions with quarterly data covering the period 2003 q1 2014 q3 we find a stable long run relationship only for diesel demand income and price our results imply that gasoline demand does not respond to income and price in the long run reflecting a shift from gasoline towards diesel induced by differential tax policies furthermore we find that transport fuel demand is price inelastic making tax on fuel a perfect tool for raising budget revenues in addition our results suggest that fuel demand responds to negative and positive price changes symmetrically

the chaning composition of income transfer programmes a public choice analysis this paper investigates the role of the interaction between the aid to families with dependent children afdc and food stamp programmes as an explanation for the decline in real income transfers experienced in the united states in the 1970s a public choice model is developed that focuses on the negative income tax features of the food stamp programme and its impact on the marginal cost of income redistribution the hypothesis developed from the theoretical model is investigated with a panel data set the econometric results suggests that the introduction of the food stamp programme did lead to a decline in real afdc transfers but that combined transfers afdc plus food stamps rose after the introduction of the food stamp programme it is further found that a flypaper effect is present which explains the strong stimulative effect from the food stamp grant on the level of income redistribution

short and long run elasticities of gasoline demand in india an empirical analysis using cointegration techniques abstract in developing countries like india consumption of petroleum products has implications on its balance of payments economic growth and fiscal deficit gasoline is one of the prime petroleum products in this paper the relationship between gasoline demand national income and price of gasoline is empirically examined using cointegration and error correction techniques the time frame of the analysis is from 1972 1973 to 1993 1994 it has been found that gasoline demand is likely to increase significantly for a given increase in the gross domestic product the increase will be larger in the long run 2 682 than in the short run 1 178 gasoline demand is relatively inelastic to price changes both in the long and short terms the error correction model has shown that gasoline demand adjusts to their respective long run equilibrium at a relatively slow rate with about 28 of adjustment taking place in the first year

a calibrated auction conjoint valuation method valuing pork and eggs produced under differing animal welfare conditions this paper develops a valuation method which generates consistent and systematic estimates of people s preferences for complex multi attribute goods by inextricably linking auction bids with conjoint ratings the advantage of the valuation approach is that it permits the estimation of people s values for many potential goods allows one to decompose people s values for a good into its sub components and permits the study of preference heterogeneity without distributional assumptions we apply the method to an important and increasingly controversial topic animal welfare the method is used to determine people s preferences for eggs and pork produced from different production systems data from experiments conducted in three diverse u s locations chicago il dallas tx and wilmington nc indicates that people are on average willing to pay 0 95 more for a dozen eggs raised in an aviary pasture system vs a cage system and are willing to pay 2 02 more for two pounds of pork chops raised in a pasture system as opposed to a crate system

modeling gasoline demand in the united states a flexible semiparametric approach abstract the focus of this paper is on the modeling and estimation of quarterly state level gasoline demand in the united states the existing literature may not appropriately evaluate the price elasticity and income elasticity of gasoline demand most studies fail to address the possible heterogeneity in gasoline demand elasticities that may arise from a variety of sources the endogeneity issue of gasoline price has remained redundant throughout the literature i address these challenges using a flexible demand model and a recently developed estimation technique the econometric approach allows for functional coefficients to accommodate the heterogeneity in demand elasticities several instrumental variables are used to investigate the endogeneity of gasoline price the estimation results provide strong evidence of heterogeneous gasoline demand elasticities across states and over time some state level attributes along with income and macroeconomic shocks are the potential sources of heterogeneity

review of key international demand elasticities for major industrializing economies abstract this paper conducts a selective review of various estimates for energy demand responses focused specially upon lower income industrializing economies rather than richer mature nations it emphasizes recent trends from empirical studies that have been published after 2000 emphasis is placed on the five major emerging or transitional economies in brazil china india mexico and russia although other important nations like chile and south korea are also discussed when studies are available the review focuses attention on the long run responses to changes in prices and income after capital stock turnover has been completed the terminology often refers to elasticities or the percentage change in energy use divided by the percentage change in price or income holding constant all other factors that could influence energy use decisions estimates cover petroleum products natural gas and electricity although the available studies often ignore coal they also include the economy wide impacts real gdp to price changes most studies have focused upon household and transportation use of liquid fuels many fewer studies have investigated fuels used by industry or commerce or for electric generation based upon the available estimates price and income elasticities for liquid fuels are generally less than one unity for many countries and sectors except for the long run income effect for transportation purposes which can range widely by country between 0 24 and 1 75 while averaging 0 94 for all countries

measuring price elasticities for residential water demand with limited information this paper exploits the seasonal and annual changes in marginal prices for water to estimate the price elasticity of demand by residential households for water it uses the changes in distributions of water used at the census block group levels in response to changes in marginal prices of water for matched months across years this strategy reduces the interaction effects of outdoor use and demographic factors in determining responsiveness to price by comparing years that vary in overall water availability the framework can recover measures of how responses to price vary with season and drought conditions the application is the urban phoenix metropolitan area jel h42 q25

short run long run and cross elasticities of gasoline demand in brazil gasoline is one of the most important of the oil derived products its importance is closely related to its participation in the value of imports of many countries and in a number of cases it is one of the determinants of their balance of payment deficit fiscal deficit and economic growth as opposed to most nations brazil has had a gasoline substitute since 1985 alcohol many studies have tried to estimate the income and price elasticities of the demand for gasoline in several countries this paper extends previous studies by estimating the cross price elasticity between gasoline and alcohol our findings indicate that alcohol is an imperfect substitute for gasoline even in the long run as a consequence the need for a new fuel substitution must be initiated long before petroleum reserves vanish

water demand under alternative price structures we estimate the price elasticity of water demand with household level data structurally modeling the piecewise linear budget constraints imposed by increasing block pricing we develop a mathematical expression for the unconditional price elasticity of demand under increasing block prices and compare conditional and unconditional elasticities analytically and empirically we test the hypothesis that price elasticity may depend on price structure beyond technical differences in elasticity concepts due to the possibility of endogenous utility price structure choice observed differences in elasticity across price structures may be due either to a behavioral response to price structure or to underlying heterogeneity among water utility service areas

the economics of brazil s ethanol sugar markets mandates and tax exemptions sugarcane in brazil is processed into sugar and or ethanol often in flex plants that can switch between the two products we develop an economic model of flex plants export demands and two domestic fuel demand curves for a blend of ethanol with gasoline consumed by conventional cars and ethanol consumed only by flex cars we analyze the market impacts of the following policies the blend mandate fixing gasoline prices below world prices the high gasoline tax and a higher tax exemption for ethanol blended with gasoline because brazilian and u s ethanol prices have become linked a change in brazilian ethanol policy or a shock in world sugar markets can now impact u s ethanol and corn prices we show that in theory each policy analyzed has an ambiguous impact on ethanol and sugar prices empirically however a low gasoline tax and a high tax exemption for ethanol used in the fuel blend reduce ethanol and sugar prices this contradicts conventional wisdom overall we find that policy reforms implemented in 2010 offset the ethanol price increase by about 27 due to outward shifts in fuel transportation and sugar export demand curves and due to a reduced sugarcane supply caused by bad weather our model illustrates the importance of brazil s ethanol policies on world commodity markets it also provides insight into how the brazilian government can adjust policies to better control domestic inflation while minimizing impacts on investment

road fuel demand and regional effects of carbon taxes in sweden abstract this study estimated national and regional level gasoline and diesel demand elasticities in sweden using county level panel data from 2001 to 2018 the estimated elasticities were used to calculate county cost effect of the swedish co2 emission reduction policy in the transport sector the national level elasticities were estimated by employing general method of moments gmm estimators while county level elasticities were calculated by considering the weight of each fuel type share at county and national levels own prices per capita income and per capita vehicle stocks were statistically significant at national level in determining gasoline and diesel demand the calculated regional price elasticities showed variation between counties with the highest being almost 4 times higher than the lowest in absolute terms a simulation of fuel taxes to achieve the swedish 2030 emission target for the transport sector under the national and regional price elasticities indicated minor differences at the national level with respect to co2 taxes costs and regressivity in the taxes the results showed considerable differences at the regional level where costs and carbon tax payments can be considerably higher for some counties with the use of national price elasticities and the opposite is the case for other counties

analysing gasoline demand elasticities a survey this paper is a survey of studies on gasoline demand although there are very many dxerent studies in this eld which sometimes appear to arrive at contradictory results we find that with proper stratification of studies by model and data type much of the contict turns to consensus in this survey we classtfy studies by data type and by ten d erent categories of model and with the exception of estimates on seasonal data which tend to be unstable and of certain inappropriate model formulations we find a fair degree of agreement concerning average short run and even long run income and price elasticities

on the variable elasticity of the demand for gasoline the case of the usa this paper tests the variable elasticity of the demand for gasoline by applying the well known box cox extended autoregressive bcea model of savin and white this model can simultaneously test for functional form and autocorrelation in a time series regression major findings are the log linear form chosen a priori in most of previous studies can be rejected in favour of the bcea model long run price elasticities varied from 1 118 in 1973 to 0 290 in 1981 and long run income elasticities declined consistently from 0 944 in 1960 to 0 452 in 1985 these findings have policy implications for more accurate forecast of gasoline demand gasoline taxes energy conservation and others

elasticities of transport fuels at times of economic crisis an empirical analysis for spain abstract this paper provides an updated calculation of the price and income responsiveness of spanish consumers of transport fuels with an explicit exploration of the effects of the recent economic crisis we examine separate gasoline and diesel demand models using a set of estimators on a panel of 16 spanish regions over the period 1999 2015 the paper confirms the persistence of low own price elasticities both for diesel and gasoline in the short and long runs it also shows that the crisis of 2008 2013 slightly increased the price elasticity of demand for transport fuels with a higher effect on diesel than on gasoline by contrary the crisis slightly reduced the income elasticity of transport fuel demand given the intensity and length of the economic recession in spain the results of this paper may be useful to anticipate the effects of domestic public policies that impact transport fuel prices as well as to advance some of the potential consequences of crises elsewhere

understanding the energy gdp elasticity a sectoral approach abstract this paper uses per capita data for 132 countries over 1960 2010 to estimate elasticities of sectoral energy use with respect to national gross domestic product gdp we estimate models in both levels and growth rates and use our estimates to sectorally decompose the aggregate energy gdp elasticity our estimates show that residential energy use is very inelastic to gdp if primary solid biofuels are counted in energy use tallies especially at low income levels residential use of electricity is more tightly linked to gdp as is energy use by the transportation industrial and services sectors agriculture typically accounts for a small share of energy use and has a modest energy gdp elasticity the aggregate energy gdp elasticity tends to be higher for countries at higher income levels in large part because traditional use of primary solid biofuels is less important gasoline prices winter temperature population and land area are among other factors influencing sectoral energy use

estimating the effect of urban density on fuel demand much of the empirical literature on fuel demand presents estimates derived from national data which do not permit any explicit consideration of the spatial structure of the economy intuitively we would expect the degree of spatial concentration of activities to have a strong link with transport fuel consumption the present paper addresses this theme by estimating a fuel demand model for urban areas to provide a direct estimate of the elasticity of demand with respect to urban density fuel demand per capita is decomposed into car stock per capita fuel consumption per kilometre and annual distance driven per car per year urban density is found to affect fuel consumption mostly through variations in the car stock and in the distances travelled rather than through fuel consumption per kilometre

gasoline demand in the oecd an application of pooling and testing procedures abstract this study utilizes a pooled inter country data set finding the long run price elasticity falls in the range 0 55 to 0 9 depending on the choice of pooled estimators the estimators included the ols within and between country estimators plus five feasible gls estimators even allowing for a ten year distributed lag on price to reflect changes in auto efficiency characteristics the within country estimator yields appreciably more inelastic estimates than did the o s estimator which was heavily influenced by the between or inter country variation this difference raises intriguing questions for future research

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

biofuels policies and fuel demand elasticities in brazil abstract biofuels are often seen by policymakers as solutions to concerns about the environment energy diversification and rural development to understand the impacts of biofuel policy however it is important to understand demand elasticities brazil a leader in biofuels provides a unique setting to increase our knowledge about biofuel policy and the interactions within and between the gasoline and ethanol markets we estimate own price cross price and income elasticities of the demand for ethanol and gasoline using a novel instrumental variable approach to control for the inherent endogeneity between supply and demand this results in own price elasticities for both fuels higher than previous literature suggests approximately 0 9 for gasoline and 1 5 for ethanol income elasticities for both fuels are approximately 0 8 we also examine the elasticity impacts following the introduction of flex fuel cars into the brazilian market by estimating the model with over 100 subsamples across time we find that cross price elasticities become positive significant and increasing but only after larger market penetration of flex fuel cars which occurred approximately three years after their introduction

price and income elasticities of residential water demand a meta analysis this article presents a meta analysis of variations in price and income elasticities of residential water demand meta analysis constitutes an adequate tool to synthesize research results by means of an analysis of the variation in empirical estimates reported in the literature we link the variation in estimated elasticities to differences in theoretical microeconomic choice approaches differences in spatial and temporal dynamics as well as differences in research design of the underlying studies the occurrence of increasing or decreasing block rate systems turns out to be important with respect to price elasticities the use of the discrete continuous choice approach is relevant in explaining observed differences

household responses to increased water rates during the california drought this paper explores the use of fixed effects and maximum likelihood techniques to es timate household responses to water price in creases during the california drought estimates are based on bimonthly meter readings from 599 single family households in the alameda county water district over the period 1982 1992 before and after the introduction of a steeply increasing block rate price structure i find that household and monthly fixed effects models are not success ful in modeling water demand with these data however maximum likelihood models that ex plicitly consider the household s response to the rate structure result in plausible estimates of wa ter demand jel q25

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

are price strategies effective in managing demand of high residential water users abstractencouraging water use efficiency and water conservation is one of the primary goals of water utility companies nationwide this study estimates price elasticity of residential water demand to measure the responsiveness of water use to price changes particularly for high water users household level water use data for high residential water users from central florida were analysed using 3 stage least square 3sls estimated price elasticity ranges between 0 07 and 0 14 this price elasticity estimate is below most of the estimates reported in the literature in absolute value the results imply that for price strategies to be effective in managing water demand of high residential water users a significant price increase would be needed overall this study highlights the importance of designing water conservation policies tailored to specific groups of customers and the importance of using these strategies effectively and fairly for different customer groups

convergence of the static estimation toward the long run effects of dynamic panel data models abstract this article focuses on the estimation of long run effects on panel data we show that the probability limit of the between estimator of a static relation whereas the true specification is a dynamic error components model converges to the long run effects

the demand for paper and paperboard econometric models for the european union cost minimization theory suggests national demand equations for paper and paperboard in which demand is a negative function of the price of paper and paperboard and a positive function of gross national product a dynamic version of this model was estimated with data from european union countries for newsprint printing and writing paper and other paper and paperboard country by country equations proved unstable pooling the data across countries with dummy variables to account for fixed country effects led to well defined short term and long term elasticities with respect to price and gross national product the hypothesis that income and price elasticities were the same across the european union countries could not be rejected at the 1 significance level for the three product groups from 1969 to 1995 most of the growth in demand had been due to the growth in national product while price increases had only a small negative effect

fuel demand on uk roads and dieselisation of fuel economy abstract because of high oil prices and climate change policy governments are now seeking ways to improve new car fuel economy thus contributing to air quality and energy security one strategy is to increase dieselisation rates of the vehicle fleet recent trends in fuel economy show improvement since 1995 however efforts need to go further if the eu voluntary agreement targets on co 2 a greenhouse gas emission standard are to be achieved trends show diesel car sales have accelerated rapidly and that the advantage of new car fuel economy of diesel cars over gasoline ones is narrowing posing a new challenge we estimate the demand for new car fuel economy in the uk in the long run consumers buy fuel economy but not in the short run we found that long term income and price changes were the main drivers to achieve improvements particularly for diesel cars and that there is no break in the trend of fuel economy induced by the agreement adopted in the 1990s policy should target more closely both consumer choice of and use of diesel cars

light fuel demand and public policies in brazil 2003 2013 abstractthe main objective of this article is to evaluate determinants of demand for light fuels in brazil between 2003 and 2013 through a vector autoregression analysis an effort was made to identify and quantify the impact of different economic variables and public policy measures adopted during this period on the surprising increase in energy consumption by brazil s light vehicle fleet the results suggest that demand for energy by the light vehicle fleet was influenced by an increase in income by a decrease in fuel prices associated with a policy designed to prevent increases in the price of gasoline from pushing the inflation rate up by a higher availability of credit for buying vehicles and by a drop in the real price of those goods with emphasis on countercyclical measures to waive the tax on industrialized products levied on new vehicles during economic downturns in the automotive industry

the energy demand in the british and german industrial sectors heterogeneity and common factors abstract this paper estimates energy demands for the german and british industrial sectors over the 1978 2004 and the 1991 2004 samples from time series models we can conclude that there is a considerable variation in the value of the coefficients across sectors even though energy demands with sensible parameters can rarely be estimated when using a panel approach the ability of some estimators to allow for diversity across subsectors was an important factor in explaining the estimates for price elasticity on the other hand correlation across panel members or common factors did not markedly influence our results with regard to the estimated parameters our preferred choice for elasticity of economic activity and price in the longer sample is 0 52 and 0 64 similar values are found in the case of the shorter samples bearing in mind the high price elasticity energy taxes can be considered an effective strategy for reducing energy consumption

demand for oil products in the gcc countries abstract the purpose of this study is to estimate the price and income elasticities of oil products demand in the gcc countries annual data spanning the period 1970 1991 were fitted to a partial adjustment model to obtain the estimates the main finding of the study is that both price and income are relatively inelastic in the short run and there has been a great variation in these elasticities among fuels and cross country

the global financial crisis understanding the global trade downturn and recovery1 this paper aims to shed light on why the downturn in global trade during the intensification of the financial crisis in 2008q4 2009q1 was so severe and synchronised across the world and also examines the subsequent recovery in global trade during 2009q2 2010q1 the paper finds that a structural imports function which captures the different and time varying import intensities of the components of total final expenditure consumption investment government expenditure exports etc can explain the sharp decline in global imports of goods and services by contrast a specification based on aggregate total expenditure cannot fully capture the global trade downturn in particular panel estimates for a large number of oecd countries based on the individual components of expenditure suggest that the high import intensity of exports at the country level can explain a significant proportion of the decline in world imports during the crisis while declines in the highly import intensive expenditure category of investment also contributed to the remaining fall in global trade at the same time the high and rising import intensity of exports also reflects and captures the rapid growth in vertical specialisation suggesting that widespread global production chains may have amplified the downturn in world trade and partly explains its high degree of synchronisation across the globe in addition the estimates find that stockbuilding business confidence and credit conditions also played a role in the global trade downturn meanwhile the global trade recovery 2009q2 2010q1 can only be partially explained by differential elasticities for the components of demand although the results confirm that the upturn in oecd imports was also driven by strong export growth and the reactivation of global production chains as well as the recovery in stockbuilding and the fiscal stimulus this may be in part because of the many policy measures that were implemented to boost global trade at that time and which cannot be captured by the specification the paper is also a pseudo real time robustness test of the specification in that the first analysis of the global trade downturn is based on the data available at the time i e october 2009 vintage while an updated analysis of the global downturn as well as the trade upturn is based on a more recent dataset i e october 2010 vintage the results for the global downturn remain robust regardless of which vintage of the dataset is used

information provision and consumer behavior a natural experiment in billing frequency abstract in this study i estimate a causal effect of increased billing frequency on consumer behavior i exploit a natural experiment in which residential water customers switched exogenously from bimonthly to monthly billing customers increase consumption by 3 5 5 in response to more frequent information this result is reconciled in models of price and quantity uncertainty where increases in billing frequency reduce the distortion in consumer perceptions using treatment effects as sufficient statistics i calculate consumer welfare gains equivalent to 0 5 1 of annual water expenditures heterogeneous treatment effects suggest increases in outdoor water use

stockpile strategy for china s emergency oil reserve a dynamic programming approach abstract china is currently accelerating construction of its strategic petroleum reserves how should china fill the spr in a cost effective manner in the short run how might this affect world oil prices using a dynamic programming model to answer these questions the objective of this paper is to minimize the stockpiling costs including consumer surplus as well as crude acquisition and holding costs the crude oil acquisition price in the model is determined by global equilibrium between supply and demand demand in turn depends on world market conditions including china s stockpile filling rate our empirical study under different market conditions shows that china s optimal stockpile acquisition rate varies from 9 to 19 million barrels per month and the optimal stockpiling drives up the world oil price by 3 7 the endogenous price increase accounts for 52 of total stockpiling costs in the base case when the market is tighter or the demand function is more inelastic the stockpiling affects the market more significantly and pushes prices even higher alternatively in a disruption drawdown from the stockpile can effectively dampen soaring prices though the shortage is likely to leave the price higher than before the disruption
