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

implicit co2 prices of fossil fuel use in switzerland abstract this study aims to assess the efficiency of the fossil fuel taxation scheme currently in effect in switzerland to this end the concept of implicit co2 prices is introduced based on which prices for different fossil fuel uses are derived implicit co2 prices are defined as the difference between actual prices paid by consumers and efficient domestic fuel prices efficient domestic fuel prices in turn consist of private production costs a uniform value added tax and only local external costs not including external costs due to co2 emissions and global climate change the resulting prices differ substantially which suggests that there is considerable cost saving potential in reducing co2 emissions in switzerland for passenger cars and air traffic the implicit prices are negative for these uses higher fuel charges would therefore be beneficial from a purely domestic perspective i e without considering the negative repercussions of global warming

structural interpretation of vector autoregressions with incomplete identification revisiting the role of oil supply and demand shocks traditional approaches to structural vector autoregressions vars can be viewed as special cases of bayesian inference arising from very strong prior beliefs these methods can be generalized with a less restrictive formulation that incorporates uncertainty about the identifying assumptions themselves we use this approach to revisit the importance of shocks to oil supply and demand supply disruptions turn out to be a bigger factor in historical oil price movements and inventory accumulation a smaller factor than implied by earlier estimates supply shocks lead to a reduction in global economic activity after a significant lag whereas shocks to oil demand do not

fdi and taxation a meta study despite the continuing political interest in the usefulness of tax competition and tax coordination as well as the wealth of theoretical analyses it still remains open whether or when tax competition is harmful moreover the influence of tax differentials on multinationals decisions is still insufficiently analyzed thus economists have increasingly resorted to empirical analysis in order to gain insights on the elasticity of fdi with respect to company taxation as a result the empirical literature on taxation and international capital flows has grown to a similar abundance during the last 25 years as the respective theoretical literature its heterogeneity leads to a rising need for concise reviews on the existing empirical evidence in this paper we extend former meta analyses on fdi and taxation in three ways first we add the most recent publications unconsidered in meta analyses up to date second we apply a different methodology by using a broad set of meta regression estimators and explicitly discuss which one is most suitable for application to our meta data third we address some important issues in research on fdi and taxation to the clarification of which meta analysis can make valuable contributions these issues are mainly the influence of variables which might moderate effects of tax differentials e g public spending the implications of using aggregate fdi data as opposed to firm level information on measured tax effects the implications of bilateral effective tax rates and the possible presence of publication bias in primary research

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

is wti crude oil market becoming weakly efficient over time new evidence from multiscale analysis based on detrended fluctuation analysis abstract this paper extends the work in tabak and cajueiro are the crude oil markets becoming weakly efficient over time energy economics 29 2007 28 36 and alvarez ramirez et al short term predictability of crude oil markets a detrended fluctuation analysis approach energy economics 30 2008 2645 2656 in this paper we test for the efficiency of wti crude oil market through observing the dynamic of local hurst exponents employing the method of rolling window based on multiscale detrended fluctuation analysis empirical results show that short term medium term and long term behaviors were generally turning into efficient behavior over time however in this way the results also show that the market did not evolve along stable conditions for long times multiscale analysis is also implemented based on multifractal detrended fluctuation analysis we found that the small fluctuations of wti crude oil market were persistent however the large fluctuations had high instability both in the short and long terms our discussion is also extended by incorporating arguments from the crude oil market structure for explaining the different correlation dynamics

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

the economic cost of global fuel subsidies by 2015 global oil consumption will reach 90 million barrels per day in part this high level of consumption reflects the fact that many countries provide subsidies for gasoline and diesel this paper examines global fuel subsidies using the latest available data from the world bank finding that road sector subsidies for gasoline and diesel totaled 110 billion in 2012 pricing fuels below cost is inefficient because it leads to overconsumption under baseline assumptions about supply and demand elasticities the total annual deadweight loss worldwide is 44 billion incorporating external costs increases the economic costs substantially

anticipation tax avoidance and the price elasticity of gasoline demand summary least squares estimates of the response of gasoline consumption to a change in the gasoline price are biased toward zero given the endogeneity of gasoline prices a seemingly natural solution to this problem is to instrument for gasoline prices using gasoline taxes but this approach tends to yield implausibly large price elasticities we demonstrate that anticipatory behavior provides an important explanation for this result gasoline buyers increase purchases before tax increases and delay purchases before tax decreases rendering the tax instrument endogenous including suitable leads and lags in the regression restores the validity of the iv estimator resulting in much lower elasticity estimates copyright 2016 john wiley sons ltd

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

governance and deforestation a meta analysis in economics abstract understanding which aspects of forest governance have the potential to effectively reduce deforestation is central to reversing trends in global deforestation there is a multitude of empirical studies examining this relationship using various measures of governance and study designs coming to diverse conclusions in order to identify the source of variation across studies this article conducts a meta analysis of 32 empirical cross country studies in the field of economics containing 227 estimates of the impact of different governance measures on deforestation using an ordered probit model we find that the choice of the governance measure is the main factor in explaining variations in the outcomes of the studies in particular studies using environmental policy ownership rights presence of environmental ngos and rule of law as measures of governance are more likely to find that better governance reduces deforestation in contrast studies using democracy and rights as a measure of governance are more likely to find that deforestation increases when governance is improved the finding that not all aspects of governance improvements are equally supportive of forest conservation suggests that more nuanced analyses of specific aspects of environmental governance are required to guide evidence based policy making

empirical studies of gasoline retailing a guide to the literature abstract this paper surveys the empirical literature on gasoline retailing which has been growing rapidly over the last three decades possibly in response to antitrust and regulatory concerns and increased availability of pricing data studies of both pricing and non price decision variables are considered in general it is found that crude oil prices are the primary driver of national price movements over time however market structure has been identified as playing a role in price dynamics equilibrium selection and price differentials across markets and stations the economic literature emphasizes the importance of heterogeneity across stations and coordination problems faced by retailers several directions for future work are suggested including the development of theory and demand estimation using high frequency station level data

energy savings and the rebound effect with multiple energy services and efficiency correlation abstract the rebound effect or the increased use of energy services following an increase in the efficiency of that service is widely studied in the literature but it is usually only considered in a single service environment such a framework ignores the potentially significant indirect rebound effects that occur through increased purchasing power for other services and does not allow for joint efficiency improvements across many services what we call efficiency correlation we develop a household production model with two energy services and distinct but simultaneous efficiency changes to test the implications of efficiency correlation on net energy elasticities and the rebound effect positively correlated efficiency choices across end uses not only increase technically feasible energy reductions but also drive additional rebound responses that erode these savings model simulations suggest that the rebound effects through the efficiency correlation channel are just as large as traditional direct and indirect rebound effects reported in the literature though they are offset by added technical energy savings moreover we find that negative correlation can significantly reverse any energy savings e g a household installs energy saving window panes but then trades in their sedan for a suv but current federal efficiency standards make this scenario unlikely this paper offers new insight into a host of additional behavioral responses to efficiency improvements particularly the incidence of efficiency correlation across different energy services and highlights its implication for realized energy savings

energy demand in the transportation sector of mexico abstract this paper report results of an analysis of the demand for energy in the mexican transport sectors focusing on the railroad air transport and motor vehicle modes the approach is an econometric one with emphasis placed on the structure for each mode for two of the modes a two stage approach is employed where in the first stage demands for services from the particular mode are modeled and in the second stage demand is treated as a derived demand from these transport services for the motor vehicle mode gasoline demand is considered as the product of gasoline consumption per vehicle times the total number of vehicles and then these components are related to economic and structural variables diesel demand of motor vehicles is modeled in a more reduced from approach the principal finding is that changes in income play a more important role in affecting energy demand than do changes in energy prices especially in the railroad and air transport sectors for the gasoline and diesel fuel demand in the monitor vehicle sector however price is of substantial importance

the impact of improved mileage on gasoline consumption a simple two equation model is presented of the short run derived demand for gasoline that incorporates both the effect of price and income on attained fuel efficiency and at the same time the effect of price income and attained fuel efficiency on miles traveled the results of this effort have provided 1 further evidence regarding the price and income elasticities of gasoline demand and more importantly 2 the first reported estimate of the short run mileage elasticity of gasoline demand these findings are important in determining appropriate and effective policies for reducing gasoline consumption in that they influence the relative effectiveness of such policies as excise taxes versus fuel efficiency standards 9 references 3 tables

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

estimates of energy subsidies in china and impact of energy subsidy reform abstract for a transitional economy such as china some energy subsidies are reasonable and sometimes even necessary for achieving social goals however with rising energy prices and environmental concerns we see conflicts emerging between energy subsidies energy demand supply fundamentals and climate change considerations energy subsidies have important implications for sustainable development through their effects on energy use efficiency and the choice of fuel source this paper applies the price gap approach to estimate china s energy subsidies results indicate that china s energy subsidies amounted to cny 356 73 billion in 2007 equivalent to 1 43 of gdp subsidies for oil products consumption are the largest followed by subsidies for the electricity and coal sectors furthermore a cge model is used to analyze the economic impacts of energy subsidy reforms our findings show that removing energy subsidies will result in a significant fall in energy demand and emissions but will have negative impacts on macroeconomic variables we conclude that offsetting policies could be adopted such that certain shares of these subsidies are reallocated to support other sustainable development measures which could lead to reducing energy intensity and favoring the environment

simulation estimation of two tiered dynamic panel tobit models with an application to the labour supply of married women a comment summary we find that the empirical results reported in chang journal of applied econometrics 2011 26 5 854 871 are contingent on the specification of the model the use of heckman s initial conditions combined with observed and not latent lagged dependent variables leads to a counter intuitive estimation of the true state dependence the use of wooldridge s initial conditions together with the observed lagged dependent variable and a proper modelling of censoring provides a much more natural estimate of the true state dependence parameters together with a clearer interpretation of the decision to participate in the labour market in the two tiered model copyright 2015 john wiley sons ltd

fossil fuel subsidies in the pacific island context analysis of the case of kiribati abstract kiribati is highly vulnerable to climate change induced sea level rise at the same time the country is also very dependent on fossil fuel imports kiribati uses price controls and tax exemptions to make fossil fuels more affordable for low income households this study reviews the subsidies on consumption of fossil fuels specifically gasoline diesel and household kerosene in kiribati and investigates their macroeconomic fiscal distributional and environmental impact the subsidies are quantified using price gap approach over a five year period the subsidies were on average aud 4 2 million when using 2011 2015 data with 2015 tax policies this is equivalent to 2 2 per cent of kiribati gdp over 2011 2014 the average fiscal impact would have been equivalent to 3 7 per cent of government revenues and 29 per cent of government health expenditure apart from being a fiscal burden the subsidies increase greenhouse gas emissions and make kiribati even more dependent on fossil fuel imports and more vulnerable to volatility in international fuel prices no evidence was found to support the argument for using the subsidies to support low income households in fact there are signs of considerable leakages to high income households which is consistent with findings from studies in other countries

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

impacts of oil price shocks on the united states economy a meta analysis of the oil price elasticity of gdp for net oil importing economies policy makers are interested in estimates of the potential economic impacts of oil price shocks particularly during periods of rapid and large increases that accompany severe supply shocks literature estimates of the economic impacts of oil price shocks summarized by the oil price elasticity of gdp span a very wide range due to both fundamental economic and methodological factors this paper presents a quantitative meta analysis of the oil price elasticity of gdp for net oil importing countries with a focus on the united states us the full range of estimates of the oil price elasticity of gdp for the us in the data is 0 124 to 0 017 accounting for different methodologies data and other factors we employ a meta regression model that controls for key determinant factors to estimate the mean and variance of the gdp elasticity across studies we use a robust estimation technique to deal with heterogeneity of the data and well known econometric issues that confront meta analysis the resulting regression model is used to simulate the oil price elasticity of gdp for the us with a mean of 0 020 and 68 confidence interval of 0 035 to 0 006 four quarters after a shock

large block transactions the speed of response and temporary and permanent stock price effects abstract the paper investigates how quickly prices attain new equilibrium levels after large block transactions and measures the associated temporary and permanent price effects we find that prices adjust within at most three trades with most of the adjustment occurring in the first trade the temporary price effect for seller initiated transactions is related to block size but the temporary price effect observed for buyer initiated transactions is no larger than that observed in 100 share trades most of the price effect associated with block trades is permanent and is related to block size regardless of the initiating party

price and income elasticities of residential and industrial electricity demand in the european union this study examines the short and long run price and income elasticities of residential and industrial electricity demand in the european union between 1996 and 2016 instrumental variable models using the between estimator as well as dynamic panel models are employed to present robust estimates and to assess the impact of different methodologies on the reported elasticities the long run price elasticity of residential electricity consumption is estimated between 0 53 and 0 56 these elasticities are more inelastic than that of industrial electricity use which is reported between 0 75 and 1 01 the choice of different econometric methodologies has only moderate impact on the estimates while long run residential income elasticity estimates are moderately inelastic and estimated around 0 61 industrial electricity use tends to be closely tied to income with elasticities between 0 76 and 1 08 electricity demand in all sectors is highly price and income inelastic in the short run additionally population density temperatures and policy measures also influence sectoral electricity use the above estimates can aid the design of european energy and environmental policy

entry barriers competition and technology adoption i build a model of technology adoption to study the quantitative effect of entry barriers on total factor productivity tfp in my model incumbent firms choose technologies that are sufficiently productive to deter entry from a potential competitor i show that higher entry barriers help to deter entry and lead to the choice of less productive technologies a novelty of my work is that i use a direct measure of entry barriers i find that reducing entry barriers from their average level in the poorest 30 of countries to their u s level leads to a sizeable increase in aggregate tfp of 12 jel o11 o43

multi objective regulations on transportation fuels comparing renewable fuel mandates and emission standards 2015 elsevier b v we compare two types of fuel market regulations a renewable fuel mandate and a fuel emission standard that could be employed to simultaneously achieve multiple outcomes such as reduction in fuel prices fuel imports and greenhouse gas ghg emissions we compare these two types of regulations in a global context taking into account heterogeneity in carbon content of both fossil fuels and renewable fuels we find that although neither the ethanol mandate nor the emission standard is certain to reduce emissions relative to a business as usual baseline at any given level of biofuel consumption in the policy region a mandate relative to an emission standard results in higher ghg emissions smaller expenditure on fuel imports lower price of ethanol blended gasoline and higher domestic fuel market surplus this result holds over a wide range of values of model parameters we also discuss the implications of this result to a regulation such as the us renewable fuel standard given recent developments within the us such as increase in shale and tight oil production and large increase in average vehicle fuel economy of the automotive fleet

a meta analysis on the price elasticity of energy demand abstract price elasticities of energy demand have become increasingly relevant in estimating the socio economic and environmental effects of energy policies or other events that influence the price of energy goods since the 1970s a large number of academic papers have provided both short and long term price elasticity estimates for different countries using several models data and estimation techniques yet the literature offers a rather wide range of estimates for the price elasticities of demand for energy this paper quantitatively summarizes the recent but sizeable empirical evidence to facilitate a sounder economic assessment of in some cases policy related energy price changes it uses meta analysis to identify the main factors affecting short and long term elasticity results for energy in general as well as for specific products i e electricity natural gas gasoline diesel and heating oil

a new unified approach to evaluate economic acceptance towards main green technologies using the meta analysis the aim of this paper is to analyze the main determinants of the economic acceptability of four green technologies gts alternative fuel vehicles energy savings in residential buildings smart meters and renewable electricity using a meta analysis on a sample of 35 selected papers which provided 245 primary data this approach allows detecting relationships across heterogeneous studies avoiding the subjectivity of qualitative surveys we implement a new two step procedure first we compute a measure of the implicit price for a kilogram of co2 avoided pco2 homogenizing the usable information for the gts considered second we conduct a meta regression using the computed pco2 values to estimate the socio economic determinants impact in general our results show a wide degree of acceptability for gts which is stronger among european citizens in particular it emerges that on average the estimated pco2 is positive for the gts considered and additional positive effects exist when respondents are confronted with an explicit reference to quantitative targets in terms of co2 abatement a clear proposal for payment timing and a specific renewable electricity mix these results indicate that information and transparency are crucial to spur gts deployment therefore to support gts market penetration public and private institutional stakeholders have to provide ad hoc information to the end users setting a clear and suitable system of prices to increase the economic value end users place on gts

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

is the evidence for ppp reliable a sustainability examination of the stationarity of real exchange rates abstract some recent time series studies testing the stationarity of real exchange rates rers produce conflicting results using nonlinear unit root tests and recursive analysis this paper tests whether the evidence on the stationarity of rers is sensitive to different numeraire currencies different sample periods covering regional and global crises and the inclusion of countries with different levels of economic or regional integration the results indicate that evidence for a stationary rer could be substantially sensitive to sample period changes but not so for the currencies of the countries involved in forming the euro area we also find that financial crises have a notable impact on testing the stationarity of rers depending on the numeraire currency used we discuss the policy implications of the findings

clean energy and international oil oil has been the world s dominant fuel for more than 50 years substitution of oil for power generation and heating has progressed since the 1970s but substitution of oil in transport remains elusive this paper examines the progress of clean energy and compares the unfolding co evolution of technologies markets and institutions with what we know about substitution of oil and technological paradigm shifts while the rhetoric in favour of clean energy is strong technologies policies and supportive infrastructure investments are still in a formative stage the transformative process will evolve over the next 10 20 years and change irreversibly the demand dynamics for oil although decline in the demand for oil is not imminent the impact of the clean energy transition on international oil is evident even now high oil prices accelerate commitment policies and market prospects for clean energy options and speed up the market readiness of substitutes for oil while 20 years appears a long time for the development and scale up of alternatives to oil it is a short period in the context of the required paradigm shift for international oil it is well within the time frame for resource rent optimization strategic planning and investment decisions high cost resource developers need to be aware copyright 2011 oxford university press

the grey paradox how fossil fuel owners can benefit from carbon taxation abstract this paper considers the distributional impact of optimal carbon taxation on fossil fuel owners a carbon emitting exhaustible resource competes with a dirtier abundant resource and a clean backstop a time dependent carbon tax is set to optimally use these resources under a cap constraint over co 2 atmospheric concentration as the cap is tightened the dirtier resource becomes less competitive compared to the exhaustible resource the competition effect but the timing and duration of extraction of the exhaustible resource is modified the timing effect we provide analytical expressions of these effects and determine conditions over size of reserves pollution contents extraction costs and demand elasticity such that the exhaustible resource owners profits increase as the ceiling is tightened calibrations for the transport and power sectors suggest that the profits of conventional oil and natural gas owners increase compared to a baseline without regulation for plausible carbon ceiling values

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

validating energy oriented cge models although cge models have received heavy usage they are often criticized as being insufficiently validated key parameters are often not econometrically estimated and the performance of the model as a whole is rarely checked against historical outcomes as a consequence questions frequently arise as to how much faith one can put in cge results in this paper we employ a novel approach to the validation of a widely utilized global cge model gtap e by comparing the variance of model generated petroleum price distributions driven by historical demand and supply shocks to the model with observed five year moving average price distributions we conclude that energy demand in gtap e is far too price elastic over this time frame after incorporating the latest econometric estimates of energy demand and supply elasticities we revisit the validation question and find the model to perform more satisfactorily as a further check we compare a deterministic global general equilibrium simulation based on historical realizations over the 2001 2006 period during which petroleum prices rose sharply along with growing global energy demands as anticipated by the stochastic simulations the revised model parameters perform much better than the original gtap e parameters in this global general equilibrium context

marginal reductions in vehicle emissions under a dual blend ethanol mandate evidence from a natural experiment among the many reasons policy makers across the world have sought to supplement fuel supplies with ethanol blended fuels are the cited environmental benefits that come with replacing a fossil fuel with a cleaner burning alternative dual blend ethanol mandates in which multiple ethanol blends are simultaneously available are one way policy markers can move forward with more aggressive mandates more quickly the recent ethanol mandate in the state of new south wales australia offers a unique natural experiment to quantify the potential environmental benefits and costs of a dual blend ethanol policy this paper estimates the impact on carbon dioxide co2 emissions from road activity that are attributable to the implementation of the new south wales ethanol requirements we find that there was a decrease in emissions due to the policy but that the decrease is relatively minor given the size of the market and that it comes at a high cost the cost was over 1200 per ton of carbon to reduce gasoline emissions by just 1 2

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

driving for fun comparing the effect of fuel prices on weekday and weekend fuel consumption abstract focusing on individual motorists in car owning households in germany this paper investigates the determinants of automobile travel with the specific aim of quantifying the effects of fuel prices and person level attributes on travel conducted over a five day week and weekend our analysis is predicated on the notion that car use is an individual decision albeit one that is dependent on intra household allocation processes thereby building on a growing body of literature that has identified the importance of socioeconomic factors such as employment status gender and the presence of children in determining both access to and use of the car to capture this two stage decision process we employ the two part model which consists of probit and ols estimators and derive elasticity estimates that incorporate both the discrete and continuous choices pertaining to car use with fuel price elasticity estimates ranging between 0 45 and 0 50 our results suggest raising prices via fuel taxes to be a promising energy conservation and climate protection measure

optimal deleveraging with nonlinear temporary price impact abstract in this paper we first propose a portfolio management model where the objective is to balance equity and liability the asset price dynamics includes both permanent and temporary price impact where the permanent impact is a linear function of the cumulative trading amount and the temporary impact is a k th between 0 and 1 order power function of the instantaneous trading rate we construct efficient frontiers to visualize the tradeoff between equity and liability and obtain analytical properties regarding the optimal trading strategies in the second part we further consider an optimal deleveraging problem with leverage constraints it reduces to a non convex polynomial optimization program with polynomial and box constraints a lagrangian method for solving the problem is presented and the quality of the solution is studied

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 bank asset and liability management model in managing its assets and liabilities in light of uncertainties in cash flows cost of funds and return on investments a bank must determine its optimal trade off between risk return and liquidity in this paper we develop a multiperiod stochastic linear programming model alm that includes the essential institutional legal financial and bank related policy considerations and their uncertainties yet is computationally tractable for realistically sized problems a version of the model was developed for the vancouver city savings credit union for a 5 year planning period the results indicate that alm is theoretically and operationally superior to a corresponding deterministic linear programming model and that the effort required for the implementation of alm and its computational requirements are comparable to those of the deterministic model moreover the qualitative and quantitative characteristics of the solutions are sensitive to the model s stochastic elements such as the asymmetry of cash flow distributions we also compare alm with the stochastic decision tree sdt model developed by s p bradley and d b crane alm is computationally more tractable on realistically sized problems than sdt and simulation results indicate that alm generates superior policies

a bayesian sampling approach to measuring the price responsiveness of gasoline demand using a constrained partially linear model partial linear models provide an intuitively appealing way to examine gasoline demand because one can examine how response to price varies according to the price level and people s income however despite their intuitive appeal partial linear models have tended to produce implausible and or erratic price effects blundell et al 2012 propose a solution to this problem that involves using slutsky shape restrictions to improve the precision of the nonparametric estimate of the demand function they propose estimating a constrained partially linear model through three steps where the weights are optimized by minimizing an objective function under the slutsky constraint bandwidths are selected through least squares cross validation and linear coefficients are estimated using profile least squares a limitation of their three step estimation method is that bandwidths are selected based on pre estimated parameters we improve on the blundell et al 2012 solution in that we derive a posterior and develop a posterior simulation algorithm to simultaneously estimate the linear coefficients bandwidths in the kernel estimator and the weights imposed by the slutsky condition with our proposed sampling algorithm we estimate a constrained partially linear model of household gasoline demand employing household survey data for the united states for 1991 and 2001 and for canada for 2006 2009 and find plausible price effects

on energy consumption and gdp studies a meta analysis of the last two decades abstract the relationship between energy consumption and gdp growth has been intensely examined in multiple frameworks set by various methods and countries this paper is a meta analysis of 51 studies published in the last two decades with worldwide data since 1949 on the relationship between energy consumption and gdp growth the aim is to systemize some of the factors that cause the variation of results in these studies our results yield evidence that the long run elasticity of gdp growth with respect to energy consumption is not independent of the method employed for cointegration the data type and the inclusion of variables such as the price level or capital in the cointegration equation also 1 increase in capital increases the elasticity of gdp with respect to energy consumption by 0 85

elasticities of gasoline demand in switzerland abstract using cointegration techniques we investigate the determinants of gasoline demand in switzerland over the period 1970 2008 we obtain a very weak price elasticity of 0 09 in the short run and 0 34 in the long run for fuel demand i e gasoline plus diesel the corresponding price elasticities are 0 08 and 0 27 our rich dataset allows working with quarterly data and with more explicative variables than usual in this literature in addition to the traditional price and income variables we account for variables like vehicle stocks fuel prices in neighbouring countries oil shocks and fuel taxes all of these additional variables are found to be significant determinants of demand

do gasoline demand elasticities vary this paper answers questions concerning gasoline demand elasticity by analyzing periods that span both increasing and decreasing prices focusing on consumer decisions about the distance driven and the automobile size us data show that efficiency changes and reduced mileages account equally for short run elasticities while automobile efficiency accounts for 90 in the long run the analysis shows a consistency that makes it useful in projecting elasticities during market disruptions and over a broad span of economic conditions in other countries 38 references dck

public acceptability of personal carbon trading and carbon tax abstract climate change is one of the greatest challenges confronting the international community requiring action to achieve deep cuts in carbon emissions the implementation of potentially uncomfortable but necessary policy measures is though critically dependent upon public acceptability this paper reports a novel application of stated preference techniques to explore the influence of key design attributes on the acceptability of a personal carbon trading scheme in isolation and when compared to a carbon tax illustrative forecasts from the models developed indicate the importance of design attributes especially the basis of the initial permit allocation for personal carbon trading and the use to which revenues are put for carbon tax results indicate that the best scheme designs could be acceptable to a majority of respondents

optimal portfolio liquidation with distress risk we analyze the problem of an investor who needs to unwind a portfolio in the face of recurring and uncertain liquidity needs with a model that accounts for both permanent and temporary price impact of trading we first show that a risk neutral investor who myopically deleverages his position to meet an immediate need for cash always prefers to sell more liquid assets if the investor faces the possibility of a downstream shock however the solution differs in several important ways if the ensuing shock is sufficiently large the nonmyopic investor unwinds positions more than immediately necessary and all else being equal prefers to retain more of the assets with low temporary price impact in order to hedge against possible distress more generally optimal liquidation involves selling strictly more of the assets with a lower ratio of permanent to temporary impact even if these assets are relatively illiquid the results suggest that properly accounting for the possibility of future shocks should play a role in managing large portfolios

the effects of the corporate average fuel efficiency standards in the us this paper examines the effects of the corporate average fuel economy standards cafe on automobile sales prices and fuel consumption first a discrete choice model of automobile demand and a continuous model of vehicle utilization are estimated using micro data from the consumer expenditure survey for 1984 1990 next the demand side model is combined with a model of oligopoly and product differentiation on the supply side with these elements in place the effects of the cafe regulation are assessed through simulations and compared to the effects of alternative policy instruments such as an increase in gasoline tax

rational habits in gasoline demand abstract the dynamics of demand for energy goods such as gasoline are complicated by investment decisions and behavioral habits both types of complication can be captured by a habits model in which past consumption enters into an agent s current utility function if the agent is forward looking or rational then habits imply his consumption of the habit forming good will be sensitive to his expectation of future market conditions in particular future prices this sensitivity implies in turn that traditional measures of price elasticity will underproject consumers responsiveness to policy interventions this paper examines the implications of rational habits on gasoline demand using a simple model encompassing myopic and rational habits i demonstrate that an agent with rational habits will respond to anticipated future price changes and react more strongly to permanent than to temporary price changes with this distinction increasing in the strength of the habit i then estimate several habits models using panel data on u s states for the years 1989 through 2008 my preferred specification yields evidence of rational habits and moreover i find consumers to be twice as responsive to tax driven price changes as to market driven price changes taxes and other policies that operate through the gasoline price are a more powerful policy instrument than traditional price elasticity would lead us to believe

how price inelastic is demand for gasoline in fuel subsidizing economies abstract in recent years governments that have historically subsidized domestic fuel consumption face an ever growing challenge in maintaining fuel subsidies and have embarked on subsidy reform this paper estimates the price and income elasticity of demand for gasoline in countries where fuel prices are government subsidized we make use of biennial panel road sector data for 32 countries over the 1998 2010 period and find demand for gasoline to be price inelastic both in the short run and long run we estimate the short run price and income elasticities at 0 05 and 0 16 and the long run price and income elasticities at 0 25 and 0 81 respectively it is our contention that concerned governments should play an active role in identifying and committing to a road map to progressively abandoning fuel subsidies they should also not be discouraged by relatively small consumption corrections in the short run a reduction in subsidies can eventually release considerable amount of resources for more crucial and potentially growth enhancing public services such as education and health

gasoline demand and car choice estimating gasoline demand using household information in recent years calls for carbon taxes as a policy tool to combat global warming have kept a discussion of the price and income elasticities of gasoline demand alive to date gasoline demand elasticity estimates are almost exclusively based on aggregate data that are subject to aggregation problems and make distributional concerns impossible to address by using household level data from the panel study of income dynamics psid and imputed fuel efficiency measures and gasoline prices i estimate household demand for gasoline and the corresponding price and income demand elasticities an attempt is made to include data on the car stock in the estimation since car portfolio and gasoline demand decisions are closely related empirical results from a selection corrected gasoline demand regression suggest low short run price and income elasticities and clear differences in gasoline demand across the population these results suggest that a gasoline tax is not likely to result in large decreases in gasoline consumption while potentially imposing hardship on identifiable segments of the population

revealed and stated preferences for co2 emissions reduction the missing link abstract in this paper we combine data collected from two strands of literature dealing with revealed preferences expressed by conventional vehicle drivers for fuel price variation and stated preferences expressed by consumers for alternative fuel vehicles we employ a meta analysis approach drawing data on 30 primary studies reflecting two important policy interventions which are fuel price taxation and subsidies for alternative fuel vehicles this is a new contribution in environmental and energy economics in that we rescale all primary information into a unique index which captures consumers economic attitude towards carbon dioxide co2 emission reduction in monetary terms focusing on the transport sector we compute the implicit price for the avoidance of a kilogram of co2 emissions named pco2 explaining the existing heterogeneity from several points of view the results of the meta analysis show that contextual and individual characteristics influence the implicit price for co2 emissions avoidance this implicit price is on average positive in the case of revealed preferences studies whereas it is negative in the stated preferences studies although there are some important geographical differences our results show that fuel taxes could be an important additional instrument for environmental policy

the demand for cars and gasoline a simultaneous approach abstract this paper develops and estimates a simple model of the demand and supply of cars and gasoline in israel focusing on an individual maximizing his life time utility function under various constraints particular emphasis is placed on the transaction cost in a car purchase and the fact that cars can be characterized by size and age factors which in turn affect running costs and maintenance costs the empirical results show that a change in the price of gasoline and or the price of new cars changes the structure of the stock of cars with respect to engine size

evaluating a seasonal fuel tax in a mass tourism destination a case study for the balearic islands abstract this paper estimates the monthly aggregate demand for diesel oil and gasoline in a mass tourism region characterized for a high level of seasonality using time series models price elasticities are estimated with special emphasis in evaluating differences between seasons in order to assess the consequences of a fuel tax applied exclusively during the high season using the case study of the balearic islands spain from january 1999 to december 2010 results from a partial adjustment model show a relatively low price elasticity evidencing how the internalizing mechanism that could be argued for introducing the tax in order to reduce transport externalities does not work additionally no statistical differences have been found between seasons for both fuels invalidating the argument that tourism activity reacts differently to host activity

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

the influence of energy efficiency on other natural resources use an input output perspective abstract energy efficiency improvements reduce the costs of energy services and under some circumstances increase the available income this generates an additional increase of consumption of goods and services that need additional energy to be produced distributed and consumed this effect is known as the indirect rebound effect in the literature however beyond this additional increase of global energy consumption there is also a variation of the use of other natural resources due to the same mechanism this effect which we label as direct and indirect cross rebound effect is generally not considered by academia nor policy making when designing and implementing energy policies this research conceptualizes this effect develops a methodology for its estimation and provides estimates for the spanish economy results show that an energy efficiency in households could increase the use of minerals and water while reducing the use of energy fossil fuels and metal ores in spain these reductions however are lower than the expected ones from an input output perspective leading to positive direct and indirect cross rebound effects between 64 6 and 74 7 for energy equivalent to direct and indirect rebound effect 48 63 for fossil fuels 84 89 for metal ores backfire for non metallic minerals 147 134 and extreme backfire for water 1191 1628

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

evidence of asymmetric behavioral responses to changes in gasoline prices and taxes for different fuel types abstract using monthly data from the spanish gasoline retail market we explore asymmetries in consumers behavioral responses to changes in gasoline prices and taxes in particular we are interested in investigating whether an increase in gasoline taxes has a more negative impact on the demand than a similar in magnitude increase in the pre tax price of gasoline for different fuel types we estimate fuel consumers responses using a rich set of robust panel data models considering potential dynamic effects and endogeneity problems we find evidence to confirm the existence of asymmetric responses for the demand of unleaded fuels and agricultural diesel fuel however we cannot support this statement for the regular diesel case for this fuel both the tax exclusive price and the tax elasticities are roughly the same this result agrees with the fact that diesel drivers tend to be better informed about changes in both fuel prices and taxes some implications in terms of fiscal policy and pollution and climate change policy are also discussed

the rebound effect for automobile travel asymmetric response to price changes and novel features of the 2000s abstract previous research suggests that the elasticity of light duty motor vehicle travel with respect to fuel cost known as the rebound effect is modest in size and probably declined in magnitude between the 1960s and the late 1990s however turmoil in energy markets during the early 2000s has raised new questions about the stability of this elasticity using panel data on u s states we revisit the simultaneous equations methodology of small and van dender 2007 and hymel et al 2010 to see whether structural parameters have changed using data through 2009 we confirm the earlier finding of a rebound effect that declines in magnitude with income but we also find an upward shift in its magnitude of about 0 025 during the years 2003 2009 in addition we find that the rebound effect is much greater in magnitude in years when gasoline prices are rising than when they are falling it is also greater during times of media attention and price volatility which explains about half the upward shift just mentioned

market power and second degree price discrimination in retail gasoline markets abstract empirical evidence of quality based second degree price discrimination is scarce the co existence of regular grade 10 ethanol blended gasoline e10 and regular grade non blended gasoline e0 in a major metropolitan city allows for second degree price discrimination to be examined while eliminating the issue of endogenous product differentiation because the two blends of gasoline are near perfect substitutes using a unique data set including daily price information for 402 retailers that sell only e0 gasoline only ethanol blended e10 gasoline or both blends simultaneously i find evidence that retailers use second degree price discrimination to segment the population between perceived lower and higher quality gasoline despite the fact that both blends can safely be used in nearly all vehicles additionally i uncover two elasticities of demand for gasoline and discuss the welfare effects of price changes and market segmentation

simulation estimation of two tiered dynamic panel tobit models with an application to the labor supply of married women in this paper a computationally practical simulation estimator is proposed for the two tiered dynamic panel tobit model originally developed by cragg 1971 the log likelihood function simulated through procedures based on a recursive algorithm formulated by the geweke hajivassiliou keane simulator is maximized the simulation estimators are then applied to study the labor supply of married women the rich dynamic structure of the labor force participation decision as well as hours worked decisions that are conditional on the participation of married women are identified by using the proposed simulation estimators the average partial effects of the participation and hours worked decisions for married women in response to fertility decisions and increases in the husband s income are also investigated it is found that the hypothesis that the fertility decision is exogenous and the hypothesis that the husband s income is exogenous to married women s labor supply function are both rejected in the dynamic and static two tiered models moreover children aged between 6 and 13 years old may have a negative impact on the hours worked decision for married women that is conditional on their participation however these children may provide some positive incentives for married women to participate in the labor force copyright 2009 john wiley sons ltd

the effect of gasoline consumption tax on consumption and carbon emissions during a period of low oil prices abstract since june 2014 international crude oil prices have fallen sharply because of the new refined oil pricing mechanism china s domestic refined oil prices fell with the international oil prices during the period from november 28 2014 to january 12 2015 the china s domestic refined oil consumption tax had been increased for three times then the lowest price of refined oil was set to protect refined oil prices from further declining through financial means used to control the prices of refined oil can the goals of oil consumption reduction and harmful emissions mitigation be realised is it reasonable to use such a way adjusting refined oil consumption tax in this paper we construct an econometric model investigate the elasticity of china s gasoline demand and then make a further research on the effect of carbon dioxide co2 emission reduction we also study the rationality of the way adjusting the consumption tax we propose some policy suggestions based on the research in the context of the frequent fluctuations in international oil prices and the rising dependence on international crude oil in china according to our study compared with the developed countries e g the united states china s gasoline demand elasticity is not high however a certain extent tax adjustment can still guide consumers towards saving energy so as to achieve the purpose of controlling gasoline consumption and reducing co2 emissions the frequent tax adjustment reveals the irrationality of the refined oil pricing mechanism and the taxes policy china has entered the 13th five development term more reform measures should be proposed to build the crude oil market and improve the taxes policy

ethanol demand in brazil regional approach abstract successive studies attempting to clarify national aspects of ethanol demand have assisted policy makers and producers in defining strategies but little information is available on the dynamic of regional ethanol markets this study aims to analyze the characteristics of ethanol demand at the regional level taking into account the peculiarities of the developed center south and the developing north northeast regions regional ethanol demand is evaluated based on a set of market variables that include ethanol price consumer s income vehicle stock and prices of substitute fuels i e gasoline and natural gas a panel cointegration analysis with monthly observations from january 2003 to april 2010 is employed to estimate the long run demand elasticity the results reveal that the demand for ethanol in brazil differs between regions while in the center south region the price elasticity for both ethanol and alternative fuels is high consumption in the north northeast is more sensitive to changes in the stock of the ethanol powered fleet and income these among other evidences suggest that the pattern of ethanol demand in the center south region most closely resembles that in developed nations while the pattern of demand in the north northeast most closely resembles that in developing nations

measuring global gasoline and diesel price and income elasticities abstract price and income elasticities of transport fuel demand have numerous applications they help forecast increases in fuel consumption as countries get richer they help develop appropriate tax policies to curtail consumption help determine how the transport fuel mix might evolve and show the price response to a fuel disruption given their usefulness it is understandable why hundreds of studies have focused on measuring such elasticities for gasoline and diesel fuel consumption in this paper i focus my attention on price and income elasticities in the existing studies to see what can be learned from them i summarize the elasticities from these historical studies i use statistical analysis to investigate whether income and price elasticities seem to be constant across countries with different incomes and prices although income and price elasticities for gasoline and diesel fuel are not found to be the same at high and low incomes and at high and low prices patterns emerge that allow me to develop suggested price and income elasticities for gasoline and diesel demand for over one hundred countries i adjust these elasticities for recent fuel mix policies and suggest an agenda of future research topics

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

income elasticity of gasoline demand a meta analysis abstract in this paper we quantitatively synthesize empirical estimates of the income elasticity of gasoline demand reported in previous studies the studies cover many countries and report a mean elasticity of 0 28 for the short run and 0 66 for the long run we show however that these mean estimates are biased upwards because of publication bias the tendency to suppress negative and insignificant estimates of the elasticity we employ mixed effects multilevel meta regression to filter out publication bias from the literature our results suggest that the income elasticity of gasoline demand is on average much smaller than reported in previous surveys the mean corrected for publication bias is 0 1 for the short run and 0 23 for the long run

price and income elasticities of demand for passenger transport fuels in spain implications for public policies abstract the significant increase in passenger transport activity cars experienced by spain and its associated increase in energy consumption have several associated negative aspects including a greater dependence on foreign energy sources and higher ghg emissions therefore reducing the level of transport activity would bring important socioeconomic and environmental benefits the aim of this paper which focuses on energy consumption in the passenger transport is fourfold 1 to provide a diagnostic of energy consumption in the spanish passenger transport system and the related problems 2 to develop a model to calculate price and income elasticities of demand for transport fuel 3 to apply this model to the spanish passenger transport sector 4 to infer policy recommendations derived from the results of the diagnostic and the model it is claimed that in view of those low price elasticities and high income elasticities and if a reduction in the scale of transport activity is deemed socially desirable a combination of instruments is necessary fuel taxes play an important role within this combination apart from their long term effects the low price elasticity of demand for transport fuel would allow the collection of a significant amount of revenues which could eventually be earmarked to encourage reductions in private transport demand and modal shifts with other instruments
