short run price and income elasticity of gasoline demand evidence from lebanon abstract we empirically estimate the demand for gasoline in the presence of multiple shifts caused by structural breaks using monthly data from lebanon covering the period 2000 m1 2010 m12 consistent with most studies in the literature our study reports that gasoline is price and income inelastic in the short run however when a single and multiple breaks are introduced the consumers responsiveness to gasoline price and income increase since both price and income elasticity are sensitive to structural changes a policy that pleads for a flat excise tax may not be optimal with respect to either the cyclical pattern of government revenues or the internalization of international environment standards

political influence motives and the choice between tariffs and quotas abstract tariffs and quotas are not symmetric under a variety of circumstances this paper pursues the implications of one such circumstance domestic market power for the political choice of protectionist instrument in the context of a political support maximization model tariffs dominate quotas in the political model in the absence of revenue seeking motives in the presence of revenue seeking ambiguity arises but limits can be placed on the range of tariff or quota levels also some welfare implications emerge

modelling the redirection of technical change the pitfalls of incorporeal visions of the economy this paper discusses attempts to represent the role of r d in the transition towards a low carbon economy through models with no meaningful granularity to inform the studied phenomenon by means of a critical analysis of acemoglu et al 2012 we show that the advantage of these models their analytical tractability does not make up for their disadvantages lack of control over policy implications and questionable numerical results on the one hand a comprehensive analysis of the results of acemoglu et al 2012 shows that even research subsidies do not pave the way for ambitious climate policies with low transitory costs thus contradicting their policy message on the other hand critical parameters such as the elasticity of substitution between clean and dirty technologies carbon sinks or the productivity of researchers are not in accordance with existing scientific knowledge we show that using more realistic parameters leads to even more pessimistic conclusions and that their model provides no leeway for overcoming them we suggest that a too highly aggregated model can only describe an incorporeal economy and comes to a deadlock we propose a more promising route for economic research in order to break this deadlock

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

preserving religious identity through education economic analysis and evidence from the us abstract this paper models the decision of religious parents to send their children to private religious schools as reflecting their desire to shield their children from external influences and thus preserve their religious identity it follows that when the share of the minority in the local population grows and outside influences become less threatening the demand for separate religious schooling among the members of the religious group decreases this pattern implies concavity in the relationship between enrollment in private and religious schooling and the share of the religious group in the population we present empirical evidence from united states county data on catholic and private school enrollment that strongly supports our theory the paper contributes to a better understanding of the demand for religious education

gasoline price volatility and the elasticity of demand for gasoline abstract we examine how gasoline price volatility impacts consumers price elasticity of demand for gasoline results show that volatility in prices decreases consumer demand for gasoline in the intermediate run we also find that consumers appear to be less elastic in response to changes in gasoline price when gasoline price volatility is medium or high compared to when it is low moreover we find that when we control for variance in our econometric model gasoline price elasticity of demand is lower in magnitude in the long run

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

income generating effects of biofuel policies a meta analysis of the cge literature abstract while the production of biofuels has expanded in recent years findings in the literature on its impact on economic growth and development remain contradictory this paper presents a meta analysis of computable general equilibrium cge studies published between 2006 and 2017 on the effect of biofuel production on economic development worldwide using 30 cge studies we found that biofuel supportive policies generated significant impacts on gdp and household incomes cge studies included in our database reported an average 0 25 percentage point increase in gdp and a 0 49 percentage point increase in household incomes we also found that results were driven by several key features of the cge studies included in our database we investigated features such as biofuel type geographic area and characteristics of the cge models employed we found that biofuel expansion has heterogeneous effects in developed versus emerging countries simulations on longer time periods and in multi country studies led to results that indicate higher impacts of biofuel expansion on gdp growth and household incomes moreover simulations with an increase in agricultural productivity indicate positive welfare impact gains unlike simulations with land expansion lastly we found that biodiesel development leads to higher welfare impact gains than that of bioethanol

immigration public education spending and private schooling this article examines the impact of immigration on private school enrollment through the mechanism of public education spending it finds that the immigrant share of population raises private school enrollment across countries by leading to a decrease in the share of public education spending the decrease is driven by responses to immigrants from culturally similar and developed countries this suggests that the role of public schools in promoting social cohesion among diverse populations is weighted against other concerns in education funding decisions in places with immigrant populations the endogeneity of immigrant share is accounted for by using an instrument constructed from gravity model estimates

energy demand in ghana a disaggregated analysis this paper presents a comprehensive analysis of energy demand in ghana by estimating demand functions for key disaggregated energy components including gasoline diesel liquefied petroleum gas lpg kerosene biomass residual fuel oil rfo and electricity our results show that energy prices income urbanization and economic structure are significant demand drivers of the different energy types in ghana with varying estimated elasticities further there is evidence of high degree of inter fuel substitution in energy demand in ghana particularly from gasoline diesel and kerosene towards lpg consumption we recommend among different policy options a customization of energy price subsidization policies especially on lpg to reduce the unintended beneficiary dilemma or spillover effect of current government policy other policies such as intensification of energy conservation programs and market entry of independent power trading companies to enhance energy service delivery through competition are also discussed

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

do overarching mitigation objectives dominate transport specific targets in the eu this research investigates if the stringent 2020 and 2050 overarching co2 mitigation objectives set out by the european union dominate its 2010 to 2020 targets specific to the transportation arena specifically its biofuel penetration objectives and gram co2per kilometre emission caps using a dynamic recursive general equilibrium model imaclim r we demonstrate that these overarching targets do not dominate the interim transportation targets when the carbon policy triggering compliance with the mitigation objectives boils down to the theoretical least cost option of uniform carbon pricing ground transportation is confirmed as quite insensitive to high carbon prices even when such prices are applied over a long term it is tempting to conclude that pursuing the mitigation objectives specific to transportation will impose unnecessary costs however because of the second best conditions prevailing in actual economies and of the risk of lock in in carbon intensive trajectories we conclude with the urgent need for some ambitious transport specific policy design research agenda

estimating the supply and demand of gasoline using tax data abstract we estimate supply and demand functions for the u s gasoline market using information from excise tax returns provided by the irs for the period 1990 2009 we find price and income elasticities of demand similar to those found using eia data we find a price elasticity of supply of 0 29 which differs from the common assumption of a perfectly inelastic short run supply curve by using a novel data source the analysis provides a robustness check of aggregate studies of gasoline demand and a consistent econometric estimate of the price elasticity of gasoline supply the results are useful in guiding tax and regulatory policies regarding gasoline consumption

elasticities of demand for gasoline in canada and the united states abstract fluctuations in the world price of oil the concern with greenhouse gas emissions and the efforts to revive the 1997 kyoto protocol have resulted in renewed interest in the estimation of elasticities of demand for gasoline in this paper a complete system of demand equations is estimated including an equation for the demand for gasoline canadian family expenditure famex and united states consumer expenditure cex survey data are used household level data permits estimation of elasticities for various household groups also differences in demand responsiveness to own price and income changes are estimated for different regions in canada and the united states demand is found to be own price and income inelastic on the whole as reported in earlier studies there is also variation in these elasticities across regions of canada and the united states however larger differences are observed with respect to household size and housing tenure than to region of residence

examining the heterogeneity in calorie income elasticities a meta analysis abstract several studies conducted over the past three decades on calorie income relationship appear to give inconclusive results this paper reviews these studies and employs meta regression analysis to examine the potential publication bias in the calorie income elasticity as well as the impact of specific study attributes on the elasticities that have been reported in the empirical literature a total of 40 empirical studies which yielded 99 estimated elasticities were considered the results indicate the presence of publication bias in the reported elasticities besides the estimates revealed evidence of positive and significant empirical effect of income on calorie intake from all the studies that goes beyond publication bias study attributes such as ranking of the journal panel data used in the analysis whether expenditure was used as proxy for income year of primary survey sample size and numbers of the years of primary data were found to have statistically significant impacts on the reported calorie income elasticities in the literature

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

environment versus growth a criticism of degrowth and a plea for a growth in recent debates on environmental problems and policies the strategy of degrowth has appeared as an alternative to the paradigm of economic growth this new notion is critically evaluated by considering five common interpretations of it one conclusion is that these multiple interpretations make it an ambiguous and rather confusing concept another is that degrowth may not be an effective let alone an efficient strategy to reduce environmental pressure it is subsequently argued that a growth i e being indifferent about growth is a more logical social aim to substitute for the current goal of economic growth given that gdp per capita is a very imperfect indicator of social welfare in addition focusing ex ante on public policy is considered to be a strategy which ultimately is more likely to obtain the necessary democratic political support than an ex ante explicit degrowth strategy in line with this a policy package is proposed which consists of six elements some of which relate to concerns raised by degrowth supporters

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

are there environmental benefits from driving electric vehicles the importance of local factors we combine a theoretical discrete choice model of vehicle purchases an econometric analysis of electricity emissions and the ap2 air pollution model to estimate the geographic variation in the environmental benefits from driving electric vehicles the second best electric vehicle purchase subsidy ranges from 2 785 in california to 4 964 in north dakota with a mean of 1 095 ninety percent of local environmental externalities from driving electric vehicles in one state are exported to others implying they may be subsidized locally even when the environmental benefits are negative overall geographically differentiated subsidies can reduce deadweight loss but only modestly

an estimation of u s gasoline demand a smooth time varying cointegration approach abstract in this paper the u s gasoline demand from 1976 to 2008 is estimated using a time varying cointegrating regression we find that price elasticity increased rapidly during the late 1970s and then decreased until 1987 after a relatively small scaled increase decrease cycle from 1987 to 2000 the price elasticity rose again after 2000 the time varying change of the elasticities may be explained by the proportion of gasoline consumption to income and fluctuation of the degree of necessity the result of the error correction model shows that a deviation from a long run equilibrium is corrected quickly and the welfare analysis illustrates there may be a gain by shifting the tax scheme from income tax to gasoline tax

signals or noise explaining the variation in recreation benefit estimates this paper uses meta analysis to summarize the benefit estimates derived from travel cost recreation demand models after reviewing approximately 200 published and unpublished studies prepared from 1970 to 1986 77 were found to report either consumer surplus estimates or sufficient information to derive them using these estimates of the consumer surplus per unit of use from each study it was possible to evaluate the influence of variables describing the site characteristics the activities undertaken at each site the behavioral assumptions and the specification decisions the findings provide clear support for using econometric methods to summarize results from diverse empirical studies they highlight the important research issues in model development and offer a consistency check to the procedures used in benefit transfer analyses for policy evaluations

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

the price elasticity of selective demand a meta analysis of econometric models of sales the author describes a meta analysis of econometric studies that estimated the elasticity of selective sales or market share to price the literature review yielded 367 suitable price elasticities

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

on the form of transfers to special interests an important question in political economy concerns the form of transfers to special interests the chicago view is that political competition leads politicians to make such transfers efficiently the virginia position is that lack of information on the part of voters leads politicians to favor inefficient sneaky methods of redistribution this paper analyzes the form of transfers in a model of political competition in which politicians have incentives to make transfers to special interests it shows that when voters have imperfect information about both the effects of policy and the predispositions of politicians inefficient methods of redistribution may be employed

parental choice of school characteristics estimation using state wide data this article attempts to proxy parental alienation from public schools across states in order to obtain measures of quality dispersion and of the educational characteristics to which families are most sensitive the indicator of alienation is the choice of private schooling since the likelihood of such choice is known from published enrollment ratios the task is to explain why they vary so widely across states of the newer hypotheses tested that of teacher strike records is strongly significant and in the expected direction other novel findings concern the share of administration teacher memberships of the national education association and the proportion of whites to nonwhites in the population

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

behaviors and housing inertia are key factors in determining the consequences of a shock in transportation costs this paper investigates the consequences of a sudden increase in transportation costs when household behaviors and building inertia are accounted for a theoretical framework is proposed capturing the interactions between behaviors transportation costs and urban structure numerical simulations show that changes in households and landowners choices reduce significantly the long term adverse effects of a shock in transportation costs indeed the shock translates over the long run into a more concentrated housing that limits households utility losses and maintains landowners income but because of building inertia the shock leads first to a long transition during which the adjustment is constrained by a suboptimal housing supply structure then households support larger losses than in the final stage though lower than with no behavior adjustment and landowners experience a large decrease in their aggregate income and an important redistribution of wealth thus behaviors and building inertia are key factors in determining the vulnerability to transportation price variability and to the introduction of climate policies our policy conclusions are that i if a long term increase in transportation costs is unavoidable because of climate change or resource scarcity a smooth change prevents to some extent the negative transition effects and ii fast growing cities of the developing world can reduce their future vulnerability to shocks in transportation costs through the implementation of policies that limit urban sprawl

decomposing the determinants of road traffic demand this study presents a decomposition of the basic fundamental determinants of road traffic and fuel demand a general framework is proposed as a means of analysing the impacts of changes in prices and income on the demand for fuel and traffic volume the objective is to provide a general basis for comparing different road traffic elasticity estimates and for understanding how a variety of different factors work together to create overall road traffic and fuel demand responses the study emphasizes relationships between different price and income elasticity measures and uses estimates from the literature to evaluate the main determinants of demand including some previously unobserved effects

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

the rebound effect microeconomic definitions limitations and extensions abstract the rebound effect results in part from an increased consumption of energy services following an improvement in the technical efficiency of delivering those services this increased consumption offsets the energy savings that may otherwise be achieved if the rebound effect is sufficiently large it may undermine the rationale for policy measures to encourage energy efficiency the nature and magnitude of the rebound effect is the focus of long running dispute with energy economics this paper brings together previous theoretical work to provide a rigorous definition of the rebound effect to clarify key conceptual issues and to highlight the potential consequences of various assumptions for empirical estimates of the effect the focus is on the direct rebound effect for a single energy service indirect and economy wide rebound effects are not discussed beginning with khazzoom s original definition of the rebound effect we expose the limitations of three simplifying assumptions on which this definition is based first we argue that capital costs form an important part of the total cost of providing energy services and that empirical studies that estimate rebound effects from variations in energy prices are prone to bias second we argue that energy efficiency should be treated as an endogenous variable and that empirical estimates of the rebound effect may need to apply a simultaneous equation model to capture the joint determination of key variables third we explore the implications of the opportunity costs of time in the production of energy services and highlight the consequences for energy use of improved time efficiency the influence of time costs on the rebound effect and the existence of a parallel rebound effect with respect to time each of these considerations serves to highlight the difficulties in obtaining reliable estimates of the rebound effect and the different factors that need to be controlled for we discuss the implications of these findings for econometric studies and argue that several existing studies may overestimate the magnitude of the effect

endogenous export subsidies as a revenue seeking activity some implications for the evolution of protection explaining the antiexport bias of trade policy requires a model in which there is some asymmetry between protection of the import competing and export sectors one asymmetry is that export subsidies require government expenditure while import tariffs raise revenue for the government a model is developed where lobbying for export subsidies is treated as a revenue seeking activity in contrast with the import competing sector it is found that there is no presumption that vicious circles exist in the export sector where a vicious circle refers to the tendency for exogenous political shocks to be amplified by an endogenous lobbying response

trade wars and trade talks when governments meet in the international arena their actions reflect the political situations at home previous studies of trade relations have focused on governments that are immune from political pressures and that act as benevolent servants of the public interest here we introduce domestic politics into the analysis of international economic relations we study the interactions between national leaders who are concerned both with providing a high standard of living to the general electorate and collecting campaign contributions from special interest groups our analysis sheds light on the determinants of the structure of protection in non cooperative and cooperative policy equilibria

bureaucracy and student performance in us public schools this paper tests the hypothesis that monopoly power of school districts allows bureaucratic expansion and fosters poor academic performance in the public school system in california evidence indicates that monopoly power is positively associated with employment of administrators and teachers and therefore supports the bureaucratic expansion hypothesis while numbers of teachers do not influence performance measures numbers of administrators are shown to positively affect performance results that suggest that too many teachers but too few administrators are employed while bureaucracy theory may explain the resource misallocation other reasons might include rising public pressures on hiring teachers over administrators spending equalization policies and the weak california economy in the period under investigation

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

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

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 much can co2 emissions be reduced if fossil fuel subsidies are removed abstract this paper analyzes consumers price elasticities of demand for fossil fuels and how a reduction of fossil fuel subsidies can lead to important reduction in co 2 emissions for various groups of countries that have relatively high fossil fuel subsidies and notably on diesel including countries in the middle east and north africa mena these countries continue to maintain significant levels of fuel subsidies with iran and saudi arabia being the largest contributors to co 2 emissions this paper illustrates that fuel price policy reforms by these countries would be an important instrument for both climate and economic policies we estimate that a reduction in subsidies to both gasoline and diesel by about 20 us cents per liter will lead to significant decreases in co 2 emissions both in the mena region and globally in iran for example the reductions could be up to 90 and 50 of current emissions generated from diesel and gasoline consumption respectively and for saudi arabia approximately 70 and 40 respectively

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

the legacy of serrano the impact of mandated equal spending on private school enrollment 1 introduction the california supreme court decision in serrano v priest in 1971 was the first state supreme court ruling to declare a state s education finance system unconstitutional 1 the suit originally filed by a class of los angeles county public school children and their parents argued that the california public school finance system was unconstitutional because of its reliance on a local property tax system under this system large differences in property wealth created enormous variations in educational resources across the state in its subsequent 1976 serrano h decision the california supreme court found that the state legislature s response to the first serrano decision was insufficient the court ordered the state legislature to follow a trial court s requirement to implement a funding formula that reduces wealth related per pupil expenditure disparities i e property tax revenue exclusive of categorical aid and special needs to 100 across school districts the serrano ii decision resulted in a nearly complete shift of the fiscal responsibility for k 12 education in california from local to state government in the aftermath of the initial serrano decision suits were filed in several other states claiming unconstitutional inequities in the state education system many of these suits were successful between 1973 and 1983 six state supreme courts new jersey 1973 connecticut 1977 washington 1978 west virginia 1979 wyoming 1980 arkansas 1983 found their systems of educational finance unconstitutional similar rulings followed in 1989 in kentucky montana and texas in 1993 in massachusetts and tennessee in 1994 in arizona and in 1997 in new hampshire ohio and vermont a third of the states education finance systems now have been ruled unconstitutional as a result of these rulings and legislative based education reforms in a number of other states education expenditure inequality has been reduced 2 this in turn has left local districts with less latitude in determining spending levels parents in richer districts are expected to be especially frustrated with the limits on spending that accompany equalization changes in state educational finance systems to gain greater equity affected average spending on education in these states the initial research on this issue focused on the california experience where raw expenditure figures reveal the dramatic change in per pupil spending in california since the initial serrano decision in 1971 in academic year ay 1969 1970 per pupil spending in california s public elementary and secondary schools was slightly greater than the national average 106 25 of the national average ranking 14th among all states however by ay 1992 1993 education expenditures in california had fallen to 85 6 of the national average and its rank had dropped to 34th silva and sonstelie 1995 concluded that education spending in california in 1989 1990 was significantly lower than they would have otherwise predicted they attributed about half of the lowered spending to the legislation following serrano ii and the other half to the growth of the student population in california but the california experience of reduced expenditures appears to be atypical manwaring and sheffrin 1997 found spending to be higher in many states as a result of litigation or legislativebased educational finance reform downes and shah 1995 similarly estimated that school finance reform raised spending in some states and lowered spending in other states murray evans and schwab 1998 found state per pupil spending rose with successful state education finance litigation the variation across states in the spending effects of education finance reforms may be due to the source court ordered or legislative and or degree e g weak reform strong reform etc of the reforms in any case there should be greater interest in supplementing what the public schools do or opting out of the public system if reforms cause spending in a state to fall

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

carpooling and driver responses to fuel price changes evidence from traffic flows in los angeles abstract we examine carpooling and driver responses to fuel price changes using a simple theoretical model we show that traffic flows in mainline lanes unambiguously decrease when fuel prices increase and this effect is stronger when the presence of a carpool lane provides a substitute to driving alone in contrast in carpool hov lanes flow can either increase or decrease these predictions are tested using 8 years of traffic flow data for 1700 locations in los angeles in our preferred specification the mean elasticity of flow with respect to fuel price is 0 136 for hov lanes for a 10 increase in fuel price this implies 10 additional carpools per hour 8 8 million per year in additional congestion costs for carpoolers and 11 3 million lower costs for mainline drivers for mainline lanes flow elasticities are 0 083 and 0 050 for highways with and without an hov lane these estimates imply that the mean highway with an hov lane experiences a 30 larger decrease in hourly flow compared to the mean highway without an hov lane flows in hov lanes show an immediate decrease following a price increase but respond positively to price increases over time which suggests time is an important input to carpool formation

the political economy of school choice linking theory and evidence abstract we derive an improved methodology for linking theoretical parameters of a political economy model of school choice to empirical values estimated by regressing local private enrollment shares on mean income the median to mean ratio religious and ethnic composition and other variables this leads us to reject the commonly maintained assumption that a coalition of ends against the middle determines local school funding and to conclude instead that the median income voter is decisive it also allows us to estimate the perceived relative efficiency advantage of private schooling which we find to be about 30 at the margin

environmental regulation of households an empirical review of economic and psychological factors abstract the literature on sustainable consumption and environmental regulation of household behavior is dominated by conceptual and normative approaches as a result many suggestions lack a firm empirical basis to overcome this deficiency econometric studies in three areas of environmentally relevant activities of households are reviewed residential use of energy generation of solid waste and recycling and residential use of water next to price and income elasticities attention is devoted to individual socio economic features and psychological factors such as attitudes knowledge perceptions and values potential psychological determinants and related insights are further examined by discussing a range of representative and illustrative statistical psychological studies of environmental behavior one important general finding is that there are very few empirical studies that systematically combine socio economic and psychological determinants a range of insights for environmental policy is derived and research recommendations are offered

interactions in swiss households energy demand a holistic approach abstract this article analyzes the interactions and possible trade offs between direct energy consumption and embodied energy requirement of households in switzerland in order to assess the net impacts of standard energy policies focusing exclusively on direct energy use direct and embodied energy demand of swiss households are estimated by combining consumption data of a national expenditure survey with data on energy intensity from life cycle analysis using a system of equations and an instrumental variable approach we find that both domains are driven by same determinants but that there is no evidence for significant substitution between them we also find an increasing effect of income on both domains with particularly important effects on embodied energy from a policy perspective our findings highlight a concern that economic growth could bring about an increasing global energy demand through energy requirement for non energy commodities however the wide spread policies targeting direct energy are unlikely to cause a substantial shift in household consumption to embodied energy

meat meets meta a quantitative review of the price elasticity of meat the price elasticity of meat has been estimated in numerous studies that utilize a variety of disparate modeling procedures in light of differences in the literature a meta analysis is performed to assess the sensitivity of the meat price elasticity to a number of characteristics including the type of meat specification of demand nature of data estimation method characteristics of the publication outlet and location of demand the results from estimating linear and box cox meta regressions coupled with different panel data treatments reveal that these characteristics have differing influence on the reported price elasticity

parental preferences and choice of school this paper provides a uk high resolution microeconometric study of parental preferences and the choice process for secondary schools given the particular geographical features of the region first preference almost entirely related to one of two state schools which is a situation that perhaps better reflects the real nature of the options faced by most parents in the uk in contrast to earlier work distance and access considerations were explicitly incorporated in the preference and choice models estimated and found to be a significant influence on parental decisions further significant factors were found dependent upon the parents actual choice of school

exogenous tariff changes with an endogenous lobbying response as pointed out by krueger 1993a 1993b changes in policy which are exogenous to the lobbying process may lead to a vicious circle of protectionism a sector which receives protection will tend to grow thereby increasing the constituency for greater protection and reducing the constituency which opposes protection the possibility of such a vicious circle is examined in the context of a trade model where capital which is immobile in the short run may lobby for a sector specific import tariff if costs associated with overcoming the free rider problem do not rise too quickly exogenous policy changes will be reinforced by the endogenous lobbying response as capital flows into the protected sector in the long run the implications of lobbying by third parties versus lobbying by the specific factors themselves are also examined

biofuel economics in a setting of multiple objectives unintended consequences this paper examines biofuels from an economic perspective and evaluates the merits of promoting biofuel production in the context of the policies multiple objectives life cycle implications pecuniary externalities and other unintended consequences the policy goals most often cited are to reduce fossil fuel use and to lower greenhouse gas emissions but the presence of multiple objectives and various indirect effects complicates normative evaluation to address some of these complicating factors we look at a several combinations of policy alternatives that achieve the same set of incremental gains along the two primary targeted policy dimensions making it possible to compare the costs and cost effectiveness of each combination of policies for example when this approach is applied to u s produced biofuels they are found to be 14 31 times as costly as alternatives like raising the gas tax or promoting energy efficiency improvements the analysis also finds the scale of the potential contributions of biofuels to be extremely small in both the u s and eu mandated u s corn ethanol production for 2025 reduces u s petroleum input use by 1 75 and would have negligible net effects on co2 emissions and although eu imports of brazilian ethanol may look better given the high costs of other alternatives this option is equivalent at most to a 1 20 reduction in eu gasoline consumption

a meta analysis on the price elasticity and income elasticity of residential electricity demand abstract price elasticity and income elasticity can quantitatively measure the impact of price volatility and income diversity on household electricity demand to analyze household electricity demand and better identify the main factors affecting residential electricity demand elasticity in previous literature a meta analysis based on a comprehensive and systematic summary of 103 articles is presented in this study the influencing factors are identified with a weighed least squares wls linear regression model to evaluate their strength the price elasticities and income elasticities are discussed from three dimensions namely short term long term and unmarked the results show that residential electricity demand is almost price inelastic and income inelastic in the short term but in the long term some residential electricity demand is price elastic and income elastic the results also reveal that residential electricity demand elasticity is affected by many factors such as time interval and sample period these conclusions can support the formulation of more effective electricity price and energy policy

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

regional finance and competition policy the canary islands petrol market market competition levels affect all agents of an economy businesses consumers and the state traditional analysis has evaluated the state s effects on the other agents but no analysis has been conducted regarding the inverse relationship thus the aim of this study is to estimate the tributary income losses that low levels of competition in the retail petrol market could cause in it using the data from canary islands autonomous community first we will use parker and roller s methodology 1997 to measure the level of competition and confirm a deficiency then using estimated rates we will determine the differences that would appear in tributary income if the market were to behave as a cournot s model our results show that the lack of competition causes a substantial loss of tributary income for this region somewhere between 5and 10 of the real income from the tax on unleaded petrol for the year 2004

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

the melting pot and school choice abstract in the united states parents are offered free public education in the mainstream culture but must pay the full cost of tuition if they educate their children privately this creates strong economic incentives for remaining within the public system which promotes the assimilation of minorities a pareto improvement can be achieved by subsidizing private education in exchange for modifying its social content so as to reduce polarization popular opposition to voucher programs that facilitate school choice without regulating cultural content may partly reflect voters concerns that such programs threaten to erode the common ground created by public education

a climate change policy induced shift from innovations in carbon energy production to carbon energy savings abstract we develop an endogenous growth model with capital labor and carbon energy as production factors and three technology variables that measure accumulated innovations for carbon energy production carbon energy savings and neutral growth all markets are complete and perfect except for research for which we assume that the marginal social benefits exceed the marginal private benefits by factor four the model constants are calibrated so that the model reproduces the relevant global trends over the 1970 2000 period the model contains a simple climate module and is used to assess the impact of induced technological change itc for a policy that aims at a maximum level of atmospheric co2 concentration 450 ppmv itc is shown to reduce the required carbon tax by more than a factor 2 and to reduce costs of such a policy by half when we do not constrain aggregate r d expenditures to benchmark levels costs are further reduced numerical simulations show that knowledge accumulation shifts from energy production to energy saving technology we discuss reasons for differences between our results and earlier results reported in the literature

tariffs subsidies and welfare with endogenous policy abstract it is a well established proposition of trade theory that in the absence of directly trade related distortions or policy goals subsidies are superior to tariffs for achieving any economic or non economic objective this paper shows that once the endogeneity of the distortion or non economic objective is allowed for the welfare ranking of various policies can be reversed the particular model analyzed is one where the level of non economic objectives that have to be fulfilled itself depends on the policy tools considered to fulfill them with this arises from the public good nature of tariffs compared to subsidies
