using loopholes to reveal the marginal cost of regulation the case of fuel economy standards estimating the cost of regulation is difficult firms sometimes reveal costs indirectly however when they exploit loopholes to avoid regulation we apply this insight to fuel economy standards for automobiles these standards feature a loophole that gives automakers a bonus when they equip a vehicle with flexible fuel capacity profitmaximizing automakers will equate the marginal cost of compliance using the loophole which is observable with the unobservable costs of strategies that genuinely improve fuel economy based on this insight we estimate that tightening standards by one mile per gallon would have cost automakers just 9 27 per vehicle in recent years jel l51 l62 q48

vehicle scrappage and gasoline policy abstract we estimate the sensitivity of scrap decisions to changes in used car values and show how this scrap elasticity produces emissions leakage under fuel efficiency standards a process known as the gruenspecht effect we first estimate the effect of gasoline prices on used vehicle values and scrappage of vehicles with different fuel economies we then estimate the scrap elasticity itself which we find to be 0 7 when applied in a model of fuel economy standards 13 16 percent of the expected fuel savings leak away through the used vehicle market this effect rivals or exceeds the importance of the often cited mileage rebound effect jel h23 l62 l78 q35 q38 q48 q58

the welfare effects of fuel conservation policies in a dual fuel car market evidence from india we estimate a model of vehicle choice and kilometers driven to analyze the long run impacts of fuel conservation policies in the indian car market we simulate the effects of petrol and diesel fuel taxes and a diesel car tax taking into account their interactions with the pre existing petrol fuel tax and car sales taxes at levels sufficient to reduce total fuel consumption by 7 the increased diesel and petrol fuel taxes both yield deadweight losses net of externalities of about 4 2010 rs l however at levels sufficient to reduce total fuel consumption by 2 the increased petrol fuel tax results in a deadweight loss per liter of fuel conserved that is greater than that caused by the diesel fuel tax this reflects both the high pre existing tax on petrol fuel and the high own price elasticities of fuel demand in india a tax on diesel cars that results in the same diesel market share as the large diesel fuel tax actually has a negative deadweight loss per liter of fuel conserved the welfare effects of all three policy instruments are positive once the external benefits of reducing fuel consumption are added to the excess burden of taxation

distributional effects of a carbon tax on car fuels in france this paper analyses the distributional effects of alternative scenarios of carbon taxes on car fuels using disaggregated french panel data from 2003 to 2006 it incorporates household price responsiveness that differs across income groups into a consumer surplus measure of tax burden carbon taxation is regressive before revenue recycling however taking into account the benefits from congestion reduction induced by the tax mitigates regressivity we show also that recycling additional revenues from the carbon tax either in equal amounts to each household or according to household size makes poorest households better off

foreign currency denominated borrowing in the absence of operating incentives abstract it is well known that corporations issue foreign currency denominated debt to hedge foreign currency cash flows with offsetting interest payments we test an alternative opportunistic motive for foreign currency denominated borrowing we do so by constructing a comprehensive sample of foreign currency denominated bonds issued by sovereign government and agency issuers with no foreign currency cash flows or foreign operations we find strong and consistent evidence that the borrowers in our sample consider cross currency differences in covered and uncovered interest yields in choosing the currency in which to denominate their international debt we estimate the average gains to opportunistic covered yield borrowing to be 4 to 18 basis points interestingly we also find that the average bond offering in our sample precedes a large and beneficial depreciation of the issue currency over the course of the following year these results support what has been a frequent conjecture in the foreign debt market

layoffs and unemployment insurance abstract this paper presents econometric evidence of a causal relationship between the frequency of layoffs and the structure of the unemployment insurance system the data are pooled time series and cross sectional observations on layoffs ui benefits ui taxes and wages annual dummy variables and industry mix variables are included to adjust for pooling weighted two stage least squares is used to adjust for aggregation and for reverse casuality the empirical results confirm the expectations of the theoretical models and indicate that ui has a substantial effect on layoff rates

annual miles drive used car prices this paper investigates whether the net benefits from owning a vehicle proxied by annual miles driven explain the price declines observed over a vehicle s life we first model the household decision on how much to drive each of its vehicles then we empirically establish that variation in household annual miles across brands explains observed price declines furthermore the effect of vehicle age on annual miles decisions and consequently on market value depends on household characteristics and the composition of the vehicle stock owned

clearing the air the costs and consequences of higher cafe standards and increased gasoline taxes abstract concerns about energy security and climate change have sparked legislators interest in reducing gasoline consumption by increasing corporate average fuel economy cafe standards using an empirically rich simulation model and cost estimates for anticipated fuel economy technologies we estimate annual costs of reducing long run gasoline consumption by 10 via a 3 8 miles per gallon increase in the standards and the potential cost savings from allowing manufacturers to buy and sell fuel economy credits maximum gasoline savings would be realized only after all existing vehicles were replaced or 14 years in our model a gasoline tax would produce greater immediate savings by encouraging people to drive less and eventually to choose more fuel efficient vehicles we demonstrate the advantage of a tax by comparing the cost of the higher cafe standards over the first 14 years against the cost of a gasoline tax that would save the same amount of gasoline over that time

distributional and efficiency impacts of increased us gasoline taxes we examine the impacts of increased us gasoline taxes in a model that links the markets for new used and scrapped vehicles and recognizes the consider able heterogeneity among households and cars household choice parameters derive from an estimation procedure that integrates individual choices for car ownership and miles traveled we find that each cent per gallon increase in the price of gasoline reduces the equilibrium gasoline consumption by about 0 2

when tax incentives drive illicit behavior the manipulation of fuel economy in the automobile industry abstract this study examines and identifies the underlying incentives for falsifying fuel economy on the part of the automobile industry using novel microdata on on road fuel consumption in japan we find a discontinuous increase in the fuel economy gap the disparity between official test results and real world fuel economy of 6 percent at the tax incentive eligibility thresholds further evidence suggests that much of the observed gap remains unexplained by driver or vehicle characteristics and that no gap is observed at similar levels of fuel economy when they are not tied to the large tax incentive eligibility our findings suggest that feebates large incentive schemes based on fuel economy levels may in turn incentivize automakers to cook the books on fuel economy figures

automakers short run responses to changing gasoline prices abstract we provide empirical evidence that automobile manufacturers use cash incentives to offset how gasoline price fluctuations affect the expected fuel expenses of automobile buyers regressions based on a database of incentives over 2003 to 2006 suggest that on average manufacturers offset 40 of the change in relative fuel costs between vehicles due to gasoline price fluctuations the results highlight that carbon taxes and emissions trading programs likely would generate substantial substitution within vehicle classes and studies that ignore manufacturer discounting likely underestimate consumer demand for fuel economy the results also have implications for the optimal design of feebate programs

consumer myopia imperfect competition and the energy efficiency gap evidence from the uk refrigerator market abstract the empirical literature on the energy efficiency gap concentrates on demand inefficiencies in the energy using durables markets and finds evidence that consumers underestimate future energy costs when purchasing a new appliance we take a broader view and also consider the impact of imperfect competition using data on the uk refrigerator market 2002 2007 we find that the average energy consumption of appliances sold during this period was only 7 2 higher than what would have been observed under a scenario with a perfectly competitive market and non myopic consumers one reason for this small gap is that market power actually reduces energy use

pounds that kill the external costs of vehicle weight heavier vehicles are safer for their own occupants but more hazardous for other vehicles simple theory thus suggests that an unregulated vehicle fleet is inefficiently heavy using three separate identification strategies we show that controlling for own vehicle weight being hit by a vehicle that is 1000 pounds heavier generates a 40 50 increase in fatality risk these results imply a total accident related externality that exceeds the estimated social cost of us carbon emissions and is equivalent to a gas tax of 0 97 per gallon 136 billion annually we consider two policies for internalizing this external cost a weight varying mileage tax and a gas tax and find that they are similar for most vehicles the findings suggest that european gas taxes may be much closer to optimal levels than the us gas tax language en

energy efficiency policy in a non cooperative world abstract in this paper we explore energy efficiency policies in the presence of a global environmental problem and international cost interdependency associated with r d activities we develop a simple model with two regions where the cost of an appliance in one region depends upon the level of energy efficiency in that region and the level of r d activities by the appliance industry in our model the cooperative outcome can be decentralized by imposing a tax on energy however we show that when regions do not cooperate they have an incentive to adopt additional instruments to increase energy efficiency the reason is that the lack of cooperation leads to under taxation of the environmental externality which in turn creates an incentive to try to reduce emissions produced abroad we illustrate this phenomenon with the californian vehicle greenhouse gas standards

the effects of transport regulation on the oil market does market power matter instruments used to regulate the consumption of oil in the transport sector include fuel taxes biofuel requirements and fuel efficiency standards however the effects that these have on oil consumption and price vary if market power is present in the oil market the directions of change in consumption and price might contrast with those in a competitive market as a result the market structure affects not only the effectiveness of the policy instruments used to reduce oil consumption but also the terms of trade and carbon leakage in particular reduced oil consumption as a result of increased fuel efficiency standards will unambiguously increase the price of oil under a monopoly

gasoline prices fuel economy and the energy paradox abstract policymakers often assert that consumers undervalue future gasoline costs when they buy automobiles we test this by measuring whether relative prices of vehicles with different fuel economy ratings fully adjust to variation in gasoline prices vehicle prices move as if consumers are indifferent between 1 00 in discounted future gas cost and 0 76 in vehicle purchase price we show how corrections for endogenous market shares and utilization measurement error and different gasoline price forecasts affect the results we also provide unique evidence of sticky information vehicle markets respond to changes in gasoline prices with up to a six month delay

the effects of the unemployment insurance payroll tax on wages employment claims and denials abstract following a 13 year period when all employers in washington paid the same unemployment insurance ui tax rate washington was forced to adopt an experience rated tax system in 1985 we use this natural experiment to explore both tax incidence and the effects of experience rating we find that industry average tax rates are largely passed on to workers through lower earnings however our estimates imply that a firm can shift much less of the difference between its tax rate and the industry average rate our results also indicate that experience rating reduces turnover and ui claims and increases claim denials

the currency denomination of long term debt in the canadian corporate sector an empirical analysis abstract a portfolio model explaining the allocation of long term debt between canadian dollar and us dollar denominated bonds is proposed and implemented the role of anticipated exchange rate changes and the specification of the adjustment process is emphasized the empirical results are consistent with the hypothesis that corporations alter their pattern of debt outstanding to issue more liabilities with the lower expected service cost these results are consistent with imperfect substitutability between canadian and us dollar denominated long term bonds the results also indicate significant difficulties inherent in estimating portfolio models of the issue of corporate bonds

do consumers recognize the value of fuel economy evidence from used car prices and gasoline price fluctuations abstract debate about the appropriate design of energy policy hinges critically on whether consumers might undervalue energy efficiency due to myopia or some other manifestation of limited rationality we contribute to this debate by measuring consumers willingness to pay for fuel economy using a novel identification strategy and high quality microdata from wholesale used car auctions we leverage differences in future fuel costs across otherwise identical vehicles that have different current mileage and therefore different remaining lifetimes by seeing how price differences across high and low mileage vehicles of different fuel economies change in response to shocks to the price of gasoline we estimate the relationship between vehicle prices and future fuel costs our data suggest that used automobile prices move one for one with changes in present discounted future fuel costs which implies that consumers fully value fuel economy

energy price shocks household location patterns and housing crises theory and implications abstract the u s housing collapse in 2007 is widely blamed for inducing a financial crisis that spread to the real economy and caused a severe and prolonged downturn this paper develops a model to investigate the role of gasoline price shocks in triggering the housing market collapse and identifies a new channel through which energy price shocks affect the financial market and the macro economy results suggest that unanticipated gasoline price shocks increase the cost of work commutes lower the value of homes away from the city center and increase foreclosure rates as homeowners either cannot afford mortgage payments amid elevated gas expenditures or seek to abandon underwater homes the model predicts that gasoline price shocks disproportionately affect suburban households that face greater exposure due to longer commutes and lower incomes empirical evidence from the 2007 08 housing collapse is presented to corroborate this theory

understanding china s urban pollution dynamics china s ongoing urban economic growth has sharply increased the population s per capita income lowered the count of people living below the poverty line and caused major environmental problems we survey the growing literature investigating the causes and consequences of china s urban pollution challenges we begin by studying how urban population and industrial growth impacts local pollution levels and greenhouse gas production as the urban population grows richer its demand for private transportation and electricity sharply increases such privately beneficial activity exacerbates urban pollution externalities facing these severe environmental challenges china s urbanites increasingly demand quality of life progress we survey the emerging literature investigating the demand for environmental progress in china progress in mitigating externalities hinges on whether the powerful central and local governments choose to address these issues we analyze the political economy of whether government officials have strong incentives to tackle lingering urban externalities we conclude by discussing future research opportunities at the intersection of environmental and urban economics jel o18 p25 p28 q53 r23 r41 r58

the allocative cost of price ceilings in the u s residential market for natural gas a direct consequence of restricting the price of a good for which secondary markets do not exist is that in the presence of excess demand the good will not be allocated to the buyers who value it the most we demonstrate the empirical importance of this allocative cost for the u s residential market for natural gas which was subject to price ceilings during 1954 89 using a household level discrete continuous model of natural gas demand we estimate that the allocative cost in this market averaged 3 6 billion annually nearly tripling previous estimates of the net welfare loss to u s consumers

optimal currency diversification for a class of risk averse international investors abstract in the framework of continuous time finance theory this paper derives the dynamic optimal consumption and portfolio rules for a risk averse international investor who consumes in fixed proportions goods produced in n different countries and holds the respective n currencies restricting the processes generating n currency prices and exchange rates to follow brownian motion optimal portfolios of eight major currencies are presented showing substantial departures from the expenditure shares and from purchasing power parity thus even under infinite risk aversion investors consuming only one good would hold a diversified currency portfolio

simpler is better predicting consumer vehicle purchases in the short run abstract when agencies such as the us environmental protection agency epa establish future greenhouse gas emissions standards for new vehicles forecasting future vehicle purchases due to changes in fuel economy and prices provides insight into regulatory impacts we compare predictions from a nested logit model independently developed for us epa to a simple model where past market share predicts future market share using data from model years 2008 2010 and 2016 the simple model outperforms the nested logit model for all goodness of prediction measures for both prediction years including changes in vehicle price and fuel economy increases bias in forecasted market shares this bias suggests price increases are correlated with unobserved increases in vehicle quality changes in preferences or brand specific changes in market size but not cost pass through for 2010 past shares predict better than a nested logit model despite a major shock the economic disruption caused by the great recession observed share changes during this turbulent period may offer upper bounds for policy changes in other contexts the largest observed change in market share across the two horizons is 6 6 for manufacturers in 2016 and 3 4 for an individual vehicle in 2010

to rebate or not to rebate fuel economy standards versus feebates we compare the welfare effects in equilibrium of two environmental regulations that aim at increasing the new cars fleet s average fuel efficiency the fuel economy standards and the feebate policies maintaining the same environmental benefit and tax revenue we simulate the implementation of each policy in france and the united states standard type policies have larger negative welfare effects up to 3 2 times those from the feebate effects on manufacturers are heterogeneous some are better of under the standard regulation the addition of a market to trade levels of fuel efficiency dominates the simple standard regulation but not always the feebate we also consider the attribute based standard technological improvements and the equivalence with fuel taxes as extensions

new vehicle characteristics and the cost of the corporate average fuel economy standard by 2016 the corporate average fuel economy cafe standard will increase by 40 this article focuses on the medium run effects of fuel economy regulation we estimate consumers willingness to pay for vehicle characteristics we employ a novel empirical strategy that accounts for the characteristics endogeneity by using variation of engine models used in vehicle models the results imply that consumers value an increase in power more than an increase in fuel economy simulations of the effects of an increase in the cafe standard suggest that regulatory costs are significantly smaller in the medium run than in the short run

biofuel subsidies versus the gas tax the carrot or the stick abstract this paper provides an analytical framework to examine the relative efficiencies of a revenue neutral biofuel subsidy and a gas tax in the presence of pre existing distortions and growing substitutability between fuels both policies are set to achieve a targeted reduction in gasoline use at the state level the model is then calibrated for a small open economy such as illinois which is one of the largest producers of biofuels such as ethanol in the u s the main result of the paper shows that raising the biofuel subsidy use reduces overall welfare by more than a higher gas tax both aimed to achieve a targeted reduction in pure gasoline the relative efficiency of the higher gas tax is primarily due to it exacerbating the pre existing distortion in the biofuel market by less than the subsidy moreover for current parameter estimates welfare improving policy combinations for achieving a targeted amount of energy security are higher gas taxes combined with lower biofuel subsidies and a lower tax on income however the preference for a gasoline labor tax swap shrinks as the elasticity of substitution between the two fuels rises

the effect of forward exchange on spot rate volatility under risk and rational expectations abstract this paper presents a multiperiod rational expectations model of a foreign exchange market in order to analyze the effect of introducing currency forward trading on measures of exchange rate volatility based on an optimizing approach to risk average agents it highlights how commercial traders and interest arbitrageurs behave facing exchange risk and forward contracting opportunities it is found that forward trading tends to stabilize spot exchange rates if the trade disturbance is the predominant random factor in the market while it exacerbates spot rate variability if the disturbance in the interest rate differential is the chief stochastic element

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

durable goods and residential demand for energy and water evidence from a field trial this article describes a household production model in which energy efficient durable goods cost less to operate so households may use them more the model is estimated using household level data from a field trial in which participants received high efficiency clothes washers free of charge the estimation strategy exploits this quasi random replacement of washers to derive precise estimates of the household production technology and a demand function for clothes washing during the field trial households increased clothes washing on average by 5 6 after receiving a high efficiency washer implying a price elasticity of 06 the complete model is used to evaluate the cost effectiveness of recent changes in minimum efficiency standards for clothes washers

internalizing team production externalities through delegation the british passenger rail sector as an example we show that in situations of team production the associated externality between workers can be partially internalized via the delegation of authority of contracting rights thus improving the overall efficiency of organizations a delegated structure provides further incentives to individuals in higher tiers of the hierarchy because it makes them residual claimants our model sheds light on recent debates about the organization of the british passenger rail sector

what do consumers believe about future gasoline prices a full understanding of how gasoline prices affect consumer behavior frequently requires information on how consumers forecast future gasoline prices we provide the first evidence on the nature of these forecasts by analyzing two decades of data on gasoline price expectations from the michigan survey of consumers we find that average consumer beliefs are typically indistinguishable from a no change forecast justifying an assumption commonly made in the literature on consumer valuation of energy efficiency we also provide evidence on circumstances in which consumer forecasts are likely to deviate from no change and on significant cross consumer forecast heterogeneity

how sensitive are consumer expenditures to retail energy prices abstract there is growing evidence that the primary effect of energy price shocks on the u s economy involves a reduction in consumer spending we quantify the direct effect on real consumption of unanticipated changes in discretionary income shifts in precautionary savings and changes in the operating cost of energy using durables the possibility of asymmetries in the response of real consumption to energy price shocks is also considered we demonstrate that linear models are consistent with the symmetric behavior of real consumption in 1979 when energy prices increased sharply and in 1986 when they fell sharply it is shown that historically energy price shocks have been an important factor in explaining u s real consumption growth but by no means the dominant factor

unemployment insurance and labor supply and demand a time series analysis for the united states abstract a disequilibrium model of the u s labor market in which the unemployment insurance system plays a key role is estimated an increase in the level of real unemployment benefits markedly lowers employment and raises real wages

the economic effects of energy price shocks large fluctuations in energy prices have been a distinguishing characteristic of the u s economy since the 1970s turmoil in the middle east rising energy prices in the u s and evidence of global warming recently have reignited interest in the link between energy prices and economic performance this paper addresses a number of the key issues in this debate what are energy price shocks and where do they come from how responsive is energy demand to changes in energy prices how do consumers expenditure patterns evolve in response to energy price shocks how do energy price shocks affect u s real output inflation and stock prices why do energy price increases seem to cause recessions but energy price decreases do not seem to cause expansions why has there been a surge in the price of oil in recent years why has this new energy price shock not caused a recession so far have the effects of energy price shocks waned since the 1980s and if so why as the paper demonstrates it is critical to account for the endogeneity of energy prices and to differentiate between the effects of demand and supply shocks in energy markets when answering these questions

are energy efficiency standards justified abstract this paper develops an analytical framework for comparing the welfare effects of energy efficiency standards and pricing policies for reducing gasoline electricity and nationwide carbon emissions the model is parameterized with us data and includes key externalities in the energy transportation sectors and possible underinvestment in energy efficiency due to misperceptions over energy savings even with large misperceptions the extra welfare gains from complementing efficient pricing policies with energy efficiency standards are zero for reducing gasoline and 5 percent for reducing electricity and when viewed as substitutes these standards forgo 60 percent or more of the potential welfare gains from corresponding pricing policies a combination of energy efficiency and emissions standards is more than three times as costly as carbon pricing when there is no misperception over energy savings and even with large misperceptions combining carbon pricing with gasoline electricity taxes is better than combining it with energy efficiency standards

automobile quality choice under pollution control regulation in this paper we develop a modified quality choice model to study the effects of various mobile source air pollution control regulations we have a single producer that supplies a fixed number of car types two but faces a spectrum of consumers differing in their valuation of car quality the car manufacturer chooses the quality levels of the two car types as well as the sales mix between the two types and the size of the market it wishes to supply by endogenizing both the sales mix and the market size while still allowing quality to be a choice variable we are able to more completely analyze the impact of any car pollution control regulation existing studies of this impact either focus on the model line adjustment response shifts in the quality array or on the price adjustment response changes in the sales mix and market size in allowing for both the model line and the price adjustment options we find that the corporate average fuel efficiency cafe standard is unambiguously welfare superior to the low emission vehicle quantity constraint lev and zero emission vehicle zev programs we also show that the effects of the cafe standard are not equivalent to those of a fuel tax as previously found and that for a given car pollution target the former is preferred to the latter

the market impact and the cost of environmental policy evidence from the swedish green car rebate we quantify the effects of the swedish gcr a program to reduce oil dependence and greenhouse gas emissions in the automobile industry we find the gcr to increase the market shares of green cars and its cost to be 109 tonco2 saved thus 5 times the price of an emission permit since the main green cars in sweden are ffvs flexible fuel vehicles which can switch between petrol gasoline and ethanol we also account for fuel choice which increases the cost of the program finally we show that consumers would have purchased ffvs regardless of the rebate provided by the gcr

the economics of attribute based regulation theory and evidence from fuel economy standards in many countries fuel economy standards mandate that vehicles meet a certain fuel economy but heavier or larger vehicles are allowed to meet a lower standard this has the perverse implication of allowing automakers to meet standards either by improving fuel economy or by increasing weight which lowers fuel economy and increases externalities related to accidents this is but one example of an attribute based regulation in which the regulation imposed on a product depends on both the externality it creates and some other attribute attribute basing potentially motivates rms and individuals to strategically alter the attribute thereby endogenously altering the stringency of the regulation this paper develops a theory of attribute basing to demonstrate the costs and benets of its use the paper then empirically examines the consequences of attribute based fuel economy standards in japan where fuel economy standards are a notched attribute based function of vehicle weight we use cross sectional and panel techniques to demonstrate that attribute based regulation has signicantly altered the distribution of vehicle weight in japan where 10 of vehicles bunch at weight notches for cars whose weight is altered in response to the policy we estimate that the alteration generates a welfare loss from the exacerbation of weight related externalities of 1 500 per unit sold which translates into a 700 million annual loss across the japanese auto market

predicting gasoline prices using michigan survey data abstract this study investigates the predictive power of michigan surveys of consumers msc data for gasoline prices specifically we utilize the msc data on both expected inflation and consumer sentiment to construct a vector autoregressive var model for forecasting gasoline prices for 2003 2014 our findings indicate that the var forecasts are superior to the comparable benchmark forecasts obtained from a univariate integrated moving average ma model in terms of both predictive information content and directional accuracy as such we conclude that the msc data on both expected inflation and consumer sentiment have significant predictive information for gasoline prices further inspection reveals that the var forecasts are particularly accurate for the period since 2008 reinforcing the notion that consumers are economically rational

are consumers myopic evidence from new and used car purchases abstract we investigate whether car buyers are myopic about future fuel costs we estimate the effect of gasoline prices on short run equilibrium prices of cars of different fuel economies we then compare the implied changes in willingness to pay to the associated changes in expected future gasoline costs for cars of different fuel economies in order to calculate implicit discount rates using different assumptions about annual mileage survival rates and demand elasticities we calculate a range of implicit discount rates similar to the range of interest rates paid by car buyers who borrow we interpret this as showing little evidence of consumer myopia jel d12 h25 l11 l62 l71 l81

the behavior of an open economy firm under flexible exchange rates most proponents and opponents of floating believe that greater variability of foreign exchange rates will increase uncertainty in international transactions and hence that the volume of international trade and financial flows will be curtailed without well developed facilities for hedging against exchange uncertainty the effects of exchange risk on merchant exporters and importers have been studied by some authors under the assumption of fixed production ethier 1973 clark 1973 hodder 1977 etc others have investigated the production behaviour of an export firm in a static context see for example baron 1976a b however the impact of the greater volatility of exchange rates upon domestic employment and capital accumulation on the one hand and upon international financial transactions on the other has received scant attention in the literature this paper establishes a dynamic model of a small competitive firm which is engaged in domestic production foreign trade through exports of its products and or imports of its inputs and financial transactions in domestic and foreign currencies since the firm faces uncertainty about future exchange rates and future prices of outputs and inputs it attempts to hedge against the risk if it is risk averse a forward foreign exchange market is assumed to exist the firm s decisions on production investment forward contracting and financing which are closely related in the model are based on exogenously given probability distributions of exchange rates and prices the paper is planned as follows section i presents a model of the firm and formulates its objective function and constraints section ii solves its maximization problem and interprets the first order conditions for short run equilibrium in particular three different roles of the firm in the forward exchange or financial market are emphasized pure hedging speculative hedging and pure speculation section iii analyses the dynamic behaviour of a typical open economy firm section iv conducts comparative dynamic exercises of the firm in a long run steady state equilibrium and discusses how exchange rate uncertainty affects the firm s optimal decisions the implications of the purchasing power parity condition are also developed section v summarizes our conclusions

the impacts of energy efficiency policies meta analysis abstract this paper attempts to quantitatively summarize the existing empirical evidence on the effects of energy efficiency policies on energy demand and on the price of associated durable goods as well as to identify the main factors that systematically affect the estimated impacts to this end a meta regression analysis of the effects of energy efficiency policies is carried out on the basis of an extensive review of the existing literature selecting those studies that analyze the impact of energy efficiency policies with respect to a business as usual setting taking into account the econometric problems associated with this type of analysis intra class correlation cross sectional dependence publication bias in pursuit of robust outcomes the results show that the studies analyzing the effects of energy efficiency policies estimate a significant impact of these policies on energy demand 10 5 8 8 and the price of related durable goods 7 9 6 the main factors that influence results are the policy instrument the targeted sector the type of country the analyzed period the consideration of free riders and the type of analysis data and publication energy demand and the sector and analyzed period price of durables

distributional effects of alternative vehicle pollution control policies abstract previous work shows that policies that subsidize new vehicles and tax size miles or gasoline efficiently reduce pollution less is known about their distributional effects this paper examines distributional effects by estimating the joint demand for vehicles and miles using the consumer expenditure survey greater price responsiveness among low income households enhances progressivity of gas or miles taxes across lower incomes and mitigates regressivity across upper incomes taxes on engine size or subsidies to new vehicles are significantly more regressive than gas or miles taxes

dynamic effects of rising oil prices on consumer energy prices in canada and the united states evidence from the last half a century abstract this paper examines the dynamic relationship between the price of crude oil and the cpi energy price sub index in canada and the u s using a markov regime switching model and the bai perron sequential method since these two series are cointegrated during the sample period january 1961 june 2013 a short run dynamic model is thus estimated for each country in which all coefficients and the error variance terms can freely switch over time between two values prevailing in regimes 0 and 1 previous studies indicate that the price of crude oil does not currently affect the aggregate cpi as much as it did in the 1970s this finding is not disputed in this paper however the sequentially determined break date as well as the time varying regime switching probabilities point to two new findings first the marginal effects of changes in oil price on consumer energy prices not the aggregate cpi have consistently increased and become more instantaneous for both countries after the western u s energy crisis of 2000 second the speed of adjustment proxied by different error correction coefficients has also risen particularly for the u s therefore oil prices exert far more positive and immediate impacts on energy costs in the post rather than pre 1999 periods

employer tax evasion in the unemployment insurance program we use unique data to analyze employer tax compliance with unemployment insurance ui provisions the data indicate that employers may have underreported 728 million of ui taxes nationally in 1987 alone to formally examine this noncompliance a theoretical model of payroll tax evasion is developed showing that increasing payroll tax rates among other things likely increases noncompliance by risk neutral firms this prediction is empirically verified the finding that ui tax evasion is systematically related to various firm characteristics suggests that ui audits may be effectively targeted by statistical profiles derived from our model thereby improving compliance
