habits costly investment and current account dynamics abstract we analyze the current account dynamics for a small country model with habit forming consumers and costly investment the model has several empirical and policy implications i it is consistent with stylized facts regarding the effects of productivity shocks and increases in fiscal spending and regarding the savings investment co movement ii the long run effect of a temporary shock on net foreign assets is often opposite to that of a permanent shock iii under strong habit persistence the welfare dynamics are sluggish so that a beneficial tax financed fiscal policy may have a harmful hangover effect on welfare

minimum unit prices for alcohol minimum unit prices mups have been proposed on the grounds that they can reduce alcohol consumption of the heaviest drinkers without significantly burdening moderate drinkers this paper examines the case for mups in an optimal tax framework such a policy can improve welfare when two conditions are both satisfied first beverage quality and quantity should be substitutes second there should be more distortion to consumption of cheaper alcohol than to more expensive varieties the consequences of a mup for the optimal corrective tax are explored with a calibrated numerical example this example illustrates how the optimal tax rate might be higher when used in isolation than when a mup is also being used

taxing consumption and other sins taxes as their primary tools to collect revenue in the rest of the world governments also use income and payroll taxes but rely much more heavily than does the united states on taxing consumption consumption taxes take many forms including general sales taxes value added taxes and excise taxes on the consumption of specific items including gasoline alcohol tobacco products firearms air travel telephone communication and others the u s government does not use a value added tax making the united states unique among high income countries and a rarity in the larger world as of 2004 at least 134 countries rely on value added taxes as a substantial source of funding value added taxes are sophisticated forms of sales taxes in which taxes are withheld by businesses according to value added at every stage of production american states do impose sales taxes on broad categories of consumer purchases but state governments are considerably smaller than national governments and their sales tax rates are very low compared to the value added tax rates used in the rest of the world the united states also imposes unusually low excise taxes even after controlling for total tax collections which are lower in the united states than they are in most high income countries the deliberate social engineering that underlies the selection of certain commodities for unusually high rates of taxation appeals less to americans than to residents of other countries moreover the sin taxes on

the hidden persuaders institutions and individuals in economic theory in his classic book the hidden persuaders vance packard claimed that large corporations manipulated consumers using advertising techniques john kenneth galbraith and others have repeated a similar view against this gary becker and george stigler have claimed that advertising is essentially informative rather than manipulative in contrast it is argued here that both of these opposed accounts of human agency neglect the more subtle and undesigned processes by which institutions bear upon and mould individuals this paper proposes a concept of reconstitutive downward causation in which institutions act upon individual habits and dispositions the mechanisms involved do not fall foul of past critiques of holism or methodological collectivism this argument involves a rehabilitation of the concept of habit in social science with far reaching implications

how is demand for natural gas determined across european industrial sectors abstract this paper estimates the response of manufacturing sectors natural gas demand to price and output changes the average response to future changes in absolute and relative prices of the manufacturing industry in an oecd country depends on the mix of manufacturing industries particularly with respect to energy intensity and substitution opportunities in production we estimate short and long run demand elasticities using a shrinkage estimator which allows heterogeneous demand responses across industries for each country our results show that price and output elasticities are heterogeneous within the same manufacturing sector across countries furthermore an output contraction due to e g demand shocks will generally have larger negative effects on gas demand than increases in natural gas prices

liberalizing the energy markets of western europe a computable equilibrium model approach using a computable equilibrium model the short run effects of a radical liberalization of the west european natural gas and electricity markets are examined in each model country oil gas coal and electricity are produced traded and consumed there are world markets for oil and coal and well integrated competitive markets for gas and electricity in western europe gas and electricity are transported and traded across markets under the assumption of ideal third party access regimes for transportation and limited capacities in the transportation networks it is found that relative to the data year 1996 radical liberalization reduces the average end user price of natural gas by around 20 and the average end user price of electricity by around 50 the supply of electricity increases by around 20 mainly due to increased coal power production after such liberalization coal power emerges with the largest market share of electricity production in western europe

agency relationships in family firms theory and evidence does owner management necessarily eliminate the agency costs of ownership drawing on agency literature and on the economic theory of the household we argue that private ownership and owner management expose privately held owner managed firms to agency threats ignored by jensen s and meckling s 1976 agency model private ownership and owner management not only reduce the effectiveness of external control mechanisms they also expose firms to a self control problem created by incentives that cause owners to take actions which harm themselves as well as those around them jensen 1994 p 43 thus shareholders have incentive to invest resources in curbing both managerialand owner opportunism we extend this thesis to the domain of the family firm after developing hypotheses which describe how family dynamics and specifically altruism exacerbate agency problems experienced by these privately held owner managed firms we use data obtained from a large scale survey of family businesses to field test our hypotheses and find evidence which suggests support for our proposed theory finally we discuss the implications of our theory for research on family and other types of privately held owner managed firms

do drinkers know when to say when an empirical analysis of drunk driving this paper presents empirical evidence that an individual s decision to drive while drunk is negatively affected by the expected full price of driving drunk the analysis usa a unique data set containing information on self reported drunk driving matched to state level drunk driving policies as well as to state excise taxes on beer these are hypothesized and found to affect drunk driving further we find interesting racial differences but surprisingly small differences by gender in the effect of socioeconomic and policy variables on drunk driving propensities

quality quantity and spatial variation of price this paper develops and implements a method for estimating price elasticities of demand using cross sectional household survey data geographically clustered households report unit values which when corrected for quality effects and for measurement error indicate the underlying spatial variation in prices and can be matched to variation in demand patterns a simple model of quality choice is proposed while the correction for measurement error exploits the clustered design of such surveys data from a 1979 household survey from the ivory coast are used to estimate price elasticities for beef meat fish cereals and starches copyright 1988 by american economic association

the welfare analysis of product innovations with an application to computed tomography scanners the main goal of this paper is to put forward a methodology for the measurement of product innovations using a value metric that is equating the magnitude of innovations with the welfare gains they generate this research design is applied to the case of computed tomography scanners a revolutionary innovation in medical technology the econometric procedure centers on the estimation of a discrete choice model the nested multinominal logit which yields the parameters of a utility function defined over the changing quality dimensions of the innovative product the estimated flow of social gains from innovation is used to compute a social rate of return to r d to explore the interrelation between innovation and diffusion and to trace the time profile of benefits and costs the latter suggesting the possible occurrence of technological cycles

demand and distance evidence on cross border shopping while many studies have documented deviations from the law of one price in international settings evidence is scarce on the extent to which consumers take advantage of price differentials and engage in cross border shopping we use data from 287 swedish municipalities to estimate how responsive alcohol sales are to foreign prices and relate the sensitivity to the location s distance to the border typical results suggest that the elasticity with respect to the foreign price is around 0 4 in the border region moving 200 400 kilometers inland reduces it to 0 2 0 1 given that cross country price differences for alcohol and other products are often caused by taxes our evidence has implications for the debate on tax competition harmonization

an analysis of the impact of open entry on price and the quality of service in the airline industry d uring the past three years there has been a gradual transition toward deregulation of the airline industry by the civil aeronautics board cab as originally proposed in the federal aviation act of 1975 and finally enacted in the airline deregulation act of 1978 this move is intended to allow for competitive pricing and freedom of entry and exit in the domestic airline markets during 1981 so far the price competition has been restricted by the cab to the offering of discount and standby fares the impact on price has been a reduction in revenue per passenger mile from 8 24 in 1977 to 8 02 in june of 1979 1 over this same period the quality of service has declined as measured by an increase in the load factor from 56 1 to 63 6 this result is consistent with most predictions regarding the impact of price competition in this industry 2 alfred kahn 1978 has argued that price competition by itself would and should result in a variety of services for consumers but that it could reduce the average quality of service via higher load factors price competition is however only one dimension of a fully competitive airline market while price competition will certainly tend to increase load factors the effect of entry should be to lower them as firms compete through scheduling frequency the interaction between these forms of competition produces a technical tradeoff between lower prices and higher quality of service and thus raises the question of what a truly competitive airline market will provide the consumer of airline services this paper examines this intrinsic tradeoff between price and quality in the provision of airline service and analyzes the implications for a competitive airline industry the presence of this tradeoff has been suggested in the theoretical models of douglas and miller 1974b and devany 1975 in both models there is purported to be an inverse relation between the load factor and the number of firms in a market due to scheduling competition and an inverse relation between the load factor and the fare level due to profit maximizing supply responses of firms serving the market 3 it is these theoretical propositions that produce a tradeoff between fare level and the quality of service and make the effects of competition in the typical airline market difficult to predict using these theoretical models as a basis this paper develops an empirical analysis of the relation between fare level open entry and the quality of service and its implications for a competitive airline market this involves first estimating the equilibrium price and load factor which results from competition in a market with a fixed number of firms then the independent effect of open entry on the competitive market outcome is identified by varying the number of firms and examining the capacity response due to scheduling competition this analysis yields the zero profit price and load factor for varying degrees of market concentration jthe profitmaximizing and output maximizing price quality combinations are also generated for the same market conditions a comparison of these alternative market solutions provides the basis for analyzing the inherent price quality tradeoff in the provision of airline service and some insight into the nature of a fully competitive airline market crucial to the analysis proposed above is an empirical estimate of the supply response of firms serving a city pair market to changes in received for publication april 23 1980 revision accepted for publication april 15 1981 university of texas at arlington and southern university of new orleans respectively i these figures are computed using data on domestic trunk carriers in all u s markets they are taken from air transport 1979 2 this prediction follows from the generally accepted theoretical model as developed by devany 1975 and douglas and miller 1974b i douglas and miller 1974a b provide some empirical evidence of the inverse relation between the average load factor and the number of firms serving the market using a crosssection sample of city pair markets operating in the united states similarly devany 1975 provides some preliminary empirical tests of his model and finds the results to be generally consistent with these theoretical propositions

taxation or regulation looking for a good anti smoking policy abstract this paper investigates the relative ability of two anti smoking policies taxes and regulation in inducing reductions in cigarette consumption and in providing incentives to stop smoking or not to start to our results based on canadian data show that cigarette demand responds to taxes elasticity of 0 28 but not to regulation while the converse is true for the proportion of smokers in the population

consumer habituation this paper examines how consumers willingness to pay for goods is determined by past patterns of consumption the central result is atheorem of interior maximum which states that willingness to pay for a good is maximized at a moderate level of habitual consumption the theorem is derived from a simple model of adaptive behavior that involves a shifting s shaped value function the detailed analysis of the impact of consumption frequency and intensity on willingness to pay reveals an unsuspected implication of diminishing sensitivity even as it leads to a formalization of consumer habituation patterns including sensitization habituation and response recovery upon withdrawal that matches and integrates the most robust empirical regularities attendant on nonassociative learning in neurobiology and behavioral psychology an examination of the implications for demand dynamics and pricing highlights deterministic recurrent and transient patterns of consumption at higher price points

a complementarity model for the european natural gas market abstract in this paper we present a detailed and comprehensive complementarity model for computing market equilibrium values in the european natural gas system market players include producers and their marketing arms which we call traders pipeline and storage operators marketers lng liquefiers regasifiers tankers and three end use consumption sectors the economic behavior of producers traders pipeline and storage operators liquefiers and regasifiers is modeled via optimization problems whose karush kuhn tucker kkt optimality conditions in combination with market clearing conditions form the complementarity system the lng tankers marketers and consumption sectors are modeled implicitly via appropriate cost functions aggregate demand curves and ex post calculations respectively the model is run on several case studies that highlight its capabilities including a simulation of a disruption of russian supplies via ukraine

u s airline deregulation its effects on passengers capital and labor his paper presents an analysis of the effects of airline deregulation on passengers business and personal first class and coach and explores how capital and labor have fared in a free market the evidence corroborates many benefits that proponents of deregulation predicted but it has not worked perfectly prices are not fully competitive and for certain dimensions service quality is down furthermore the contestability hypothesis as applied to the airline industry does not withstand statistical examination

applied welfare economics with discrete choice models economists have been paying increasing attention to the study of situations in which consumers face a discrete rather than a continuous set of choices such models are potentially very important in evaluating the impact of government programs upon consumer welfare but very little has been said in general regarding the tools of applied welfare economics indiscrete choice situations this paper shows how the conventional methods of applied welfare economics can be modified to handle such cases it focuses on the computation of the excess burden of taxation and the evaluation of quality change the results are applied to stochastic utility models including the popular cases of probit and logit analysis throughout the emphasis is on providing rigorous guidelines for carrying out applied work this abstract was borrowed from another version of this item

new estimates of the optimal tax on alcohol in this paper i use a new data set to estimate the optimal alcohol tax rate as a benchmark the empirical results imply that the optimal tax rate is over 100 percent of the net of tax price however alcohol taxation is a second best solution to the problems associated with alcohol abuse i conclude that the optimal alcohol tax rate would be much lower if punishment for drunk driving were more certain and severe government provision of information about the health consequences of heavy drinking would also remove part of the efficiency rationale for alcohol taxes

does increased extraction of natural gas reduce carbon emissions without an international climate agreement extraction of more natural gas could reduce emissions of co2 as more clean natural gas may drive out dirty coal and oil using a computable equilibrium model for the western european electricity and natural gas markets we examine whether increased extraction of natural gas in norway reduces global emissions of co2 we find that both in the short run and in the long run total emissions are reduced if the additional quantity of natural gas is used in gas power production in norway if instead the additional quantity is exported directly total emissions increase both in the short run and in the long run however if modest co2 taxes are imposed increased extraction of natural gas will reduce co2 emissions also when the additional natural gas is exported directed

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

trade and price variation in an integrated european power market this paper examines the potential gains in terms of increased social surplus from integrating the power markets in europe and assesses the scope for free seasonal and diurnal trade in a setting of third party access tpa we construct an equilibrium model at the level of the wholesale markets taking account of the existing power generating infrastructure of varying flexibility as well as the existing transmission network interconnecting the countries involved the model indicates an overall gain from integrating the power markets electricity prices are substantially reduced for all regions involved thus implying a significant redistribution of income from producers to consumers trade flourishes with regions establishing themselves as either pure exporters pure importers or as intermediaries acting as transit countries

consumer electricity and gas prices across australian capital cities structural breaks effects of policy reforms and interstate differences abstract we detect and analyze the most significant structural changes in the quarterly growth rate of consumer electricity and gas prices in australia and estimate their corresponding seasonal effects to do so we apply the general modelling framework of the bai perron breaking regression to all available quarterly data for capital cities individually and australia as a whole 1989q3 2017q2 retail energy prices in most australian states were deregulated in the 2000s we find that increases in average quarterly growth rates of electricity and gas prices consistently occurred in the third september quarter and find very few instances of increases in any other quarters of the year in the post deregulation period price increases are significantly higher than in the pre deregulation era results for some capital cities are stark in perth third quarter growth in electricity prices has been five times higher after the structural break in australia as a whole third quarter growth in gas prices has been three times higher after the structural break we discuss several possible explanations for energy price rises in the period since deregulation

price knowledge in household demand for utility services a household s decision to acquire price knowledge is endogenous in the demand for utility services and may affect elasticities and consumption levels a simultaneous equation model with endogenous switching is developed to evaluate the effects of price knowledge and other sources of heterogeneity results indicate informed households were more responsive to average and marginal price signals informed households also use less water but this is due to heterogeneity rather than price knowledge controlling for heterogeneity price knowledge actually increases monthly water usage the implications of accounting for differences in price knowledge in utility demand modeling and demand management policy are discussed

water on fire gains from electricity trade in light of the ongoing liberalization of electricity trade in the nordic countries and perhaps in northern europe we argue that gains from electricity trade may be different from those traditionally associated with comparative advantages and economies of scale in particular we consider gains arising from the exploitation of technological complementarities between hydro and thermal systems our theoretical framework highlights essential features of the two systems and allows for an analysis of effects of trade we study three trading regimes which may arise either endogenously or because of trade regulations day night power exchange seasonal energy banking and unbalanced trade the analysis suggests that gradual trade liberalization may be costly

the economic functioning of online drugs markets abstract the economic functioning of online drug markets using data scraped from online platforms is studied analysis of over 1 5 million online drugs sales shows online drugs markets tend to function without the significant moral hazard problems that a priori one might think would plague them only a small proportion of online drugs deals receive bad ratings from buyers and online markets suffer less from problems of adulteration and low quality that are a common feature of street sales of illegal drugs furthermore as with legal online markets the market penalizes bad ratings which subsequently lead to significant sales reductions and to market exit the impact of the well known seizure by law enforcement of the original silk road and the shutdown of silk road 2 0 are also studied together with the exit scam of the market leader at the time evolution there is no evidence that these exits deterred buyers or sellers from online drugs trading as new platforms rapidly replaced those taken down with the online market for drugs continuing to grow

rational exuberance at the mall addiction to carrying a credit card balance the becker murphy model of rational addiction is tested with new zealand credit card debt data the results clearly favour the rational addiction model over the myopic backward looking model the estimated short run and long run price elasticities are 0 58 and 2 32 respectively and the estimated rate of time preference is 6 7 per quarter

the effects on competitiveness of coordinated versus unilateral fiscal policies reducing ghg emissions in the eu an assessment of a 10 reduction by 2010 using the e3me model abstract international competitiveness effects from coordinated and uncoordinated multilateral policies to reduce co 2 emissions from 11 member states of the eu by 2010 are compared with those from unilateral policies to achieve a 10 cut in each member state alone the paper presents the results from four projections using a large scale integrated regionalised e3 model of the eu estimated on time series cross section data 1968 93 with international trade treated as between each member state and a european transport and distribution network the 10 reduction is achieved by additional excise duties incremented every year 1999 to 2010 according to the carbon contents of fuels with special with special treatment of electricity taxed on outputs not inputs with revenues recycled via reductions in employers social security contributions multilateral coordinated policies require a common tax rate of 156 ecu per tonne carbon 1999 prices which rises to an average of 165 ecu per tonne with a wide range between regions when policies are uncoordinated all the tax shift projections show double dividends for emission reduction and employment gain for all member states unilateral policies do not show much carbon leakage but they show smaller gains for output and employment effects for price competitiveness appear to be small and mixed with serious losses appearing only for the netherlands and for metals and chemicals especially for unilateral action

advertising and us alcoholic beverage demand system wide estimates the effects of advertising on consumption of alcoholic beverages in the us are analysed the goal is to obtain evidence on the importance of advertising at the level of beverage demand beer wine spirits and for total consumption of alcohol per capita gallons of ethanol a three equation conditional demand system is estimated that includes own and cros beverage advertising as explanatory variables four models of the differential demand system are estimated including the rotterdam aid cbs and nbr models using annual us data for the period 1964 90 on beverage consumption prices expednitures and real advertising estimates are obtained of the complete matrix of own and cross elascities for each beverage price and advertising at the beverage level the results indicate a positive butr very small effect of advertising on beverage consumption with most of the impact due to wine advertising and non due to beer advertising there is no efect of advertising in the composite demand function for al

a note on pricing of hub and spoke networks abstract the difference between competitive and monopolistic pricing of airlines hub and spoke networks is examined it is found that under reasonable cost conditions pass through passengers pay lower prices per mile than those originating or ending at the hub thus higher per mile prices in large hubs do not necessarily signal market power

motives for private transfers over the life cycle an analytical framework and evidence for peru abstract this paper tests for the motives for private income transfers we consider two motives altruism and exchange the question of private transfer motives is important because such motivation can influence the effects of public income transfers on the distribution of income using a household survey for peru we find that transfer amounts received increase with recipient pre transfer income which contradicts a key prediction of the strong form of the altruism hypothesis but is consistent with exchange we also find that capital market imperfections are likely to be an important cause of private transfers and that social security benefits crowd out the incidence of private transfers

excise tax avoidance the case of state cigarette taxes we conduct an applied welfare economics analysis of cigarette tax avoidance we develop an extension of the standard formula for the optimal pigouvian corrective tax to incorporate the possibility that consumers avoid the tax by making purchases in nearby lower tax jurisdictions to provide a key parameter for our formula we estimate a structural endogenous switching regression model of border crossing and cigarette prices in illustrative calculations we find that for many states after taking into account tax avoidance the optimal tax is at least 20 smaller than the standard pigouvian tax that simply internalizes external costs our empirical estimate that tax avoidance strongly responds to the price differential is the main reason for this result we also use our results to examine the benefits of replacing avoidable state excise taxes with a harder to avoid federal excise tax on cigarettes

ambiguous changes in product quality economic goods are frequently sold according to a price per unit quantity where the quantity characteristic does not measure all the economically important characteristics of the good milk is sold by the quart automobiles rented by the mile physicians services bought by the visit and tennis lessons by the hour in all cases heterogeneous units are available in the market and the price per unit quantity depends upon the amount of the unpriced characteristic contained in each unit the per quart price of milk depends upon the butterfat content the mileage costs of automobile rentals on the cars make and the price per unit time for personal services on the providers skill and training the common distinction made between these variants of the same good is that they differ in quality where quality refers to the amounts of the unpriced attributes contained in each unit of the priced attribute thus milk is packaged according to the attribute milk liquid and the quality of milk refers to the ratio of butterfat per unit of liquid 2 this paper considers some of the unique aspects of the economics of supply and demand under this situation where products contain at least two desired attributes only one of which is quantified and measured prior to purchase product quality is here defined by the ratio of the second quality attribute per unit of the measured quantity attribute 3 this simple specification of quality allows a direct link between standard economic models of related products and the economics of variable product quality previous analyses which treat quality simply as a shift parameter in the demand function are shown to obscure the actual subtleties of supply and demand with variable endogenous quality 4 the paper proceeds by first examining the efficient quality and quantity and the competitive equilibrium the market equilibrium under monopoly is then contrasted in the second section the general theme of the

do drunk drivers pay their way a note on optimal penalties for drunk driving this paper uses a simple framework to describe optimal penalties for drunk driving and reviews available data to judge current policies against this standard the analysis suggests that policies should be designed so that the penalties paid by drunk drivers equal the value of the increased risks drunk drivers impose on others current penalties appear to be too lenient implying that current levels of drunk driving are too high

illicit drug use and labour market achievement evidence from the uk this study using data from the british crime survey bcs examines the effect of drug use on occupational achievement it starts by attempting to overcome the identification problem that results from the limited set of drug use questions presented in the bcs taking this into account and allowing for the endogeneity of drug use in equations for unemployment and labour market outcomes that a mild positive association with soft drugs and occupational achievement is observed that diminishes with age this relationship holds for males but not for females in contrast it is also found that past use of hard drugs significantly increases the likelihood of current unemployment although it appears to be unrelated to occupational success conditional on achieving employment

temporal regulation and intertemporal substitution the effect of banning alcohol at college football games a wide variety of consumption goods and activities are regulated and in a wide variety of ways excise taxes are levied on the consumption of tobacco products alcoholic beverages playing cards and gasoline consumption of certain narcotics pesticides and unsafe products are quantity controlled even prohibited in some cases driving a car getting married gambling in a legal casino and drinking alcoholic beverages are regulated on the basis of age of the consumer smoking is often restricted to designated smoking areas so called blue laws regulate the hours and days that retail businesses can operate hunting and fishing are restricted to specific locations and specific times of the year this paper is concerned with the regulation of time and place of consumption or temporal regulation for some goods temporal regulation can be rationalized on the basis of controlling negative externalities the induced substitution of consumption into other periods and locations presumably reduces the magnitude of the externality cigarette smoking hunting and fishing fit into that category confining smoking to certain times and locations may not reduce total smoking output but it may reduce the amount of the tobacco smoke externality 1 restricting hunting and fishing to certain times of the year reduces the impact of the common pool problem on the steady state stock of animals and fish in these cases increased consumption in other periods is not a policy problem alcohol however is a different story regulation of the consumption of alcohol is usually rationalized as a way of

the simple analytics of tobacco taxation with illegal supply this paper examines the impact of tobacco excise taxes where legal and illegal supplies coexist the government s objective is to minimize cigarettes smoked in the economy or to maximize revenue or to minimize illegal activity it reacts to a competitive illegal supply in an adjoining jurisdiction a model of consumer choice is used to demonstrate how demand response to tax changes can yield counterintuitive results while the model mimics the canadian market similar situations characterize the us and european markets a novel element of the paper is the treatment of externalities on the supply side rather than the demand side resume analytique simple des taxes sur le tabac quand il y a offre illegale ce memoire examine l impact des taxes sur la vente de tabac quand des offres legale et illegale coexistent l objectif du gouvernement est de minimiser les cigarettes fumees dans l economie ou de maximiser le revenu fiscal ou de minimiser l activite illegale il doit prendre en compte l offre concurrentielle illegale dans une juridiction contigue on utilise un modele de choix du consommateur pour montrer comment la reaction de la demande aux changements dans les taxes peut engendrer des resultats contre intuitifs bien que le modele soit concu pour le marche canadien on trouve des situations avec des caracteristiques similaires dans les marches americain et europeens un element novateur du memoire est sa prise en compte des externalites du cote de l offre plutot que du cote de la demande

dynamic corrective taxes with time varying salience abstract economies across the globe are becoming increasingly cashless and many payment systems have become automated driving a temporal wedge between consumption and payment and generally making the costs of consumption intermittently salient since this inconsistent price salience alters demand elasticities it is a particular concern for goods that generate externalities and the price based policies deployed to address them this paper derives optimal dynamic corrective taxes for suboptimal and persistent consumption decisions these taxes depend on the agent s ability to commit to a future consumption path we also characterize a second best constant tax and the excess burden from time invariant tax rates when calibrated to u s residential electricity consumption the model shows that the second best constant tax is more than twice the marginal external cost of carbon emissions

quantity quality and the welfare effects of us airline deregulation in this paper we employ a method for estimationg quality adjusted demand to calculate measures of the change in consumer suruplus due to us airline deregulation the quality adjusted estimates of the price elasticity of demand indicate that consumers are from 25 to 50 more sensitive to changes in air fares than unadjusted estimates would suggest changes in unadjusted consumer surplus overstate the net welfare gains from deregulation by roughly a factor of two strongly suggesting that adjustments for quallity of service are essential to welfare analysis of regulatory changes in this industry

taxing to control social costs the case of alcohol whether taxation of alcoholic beverages is an appropriate means of reducing social costs of alcohol consumption is a continuing public policy issue some argue that the public health costs and other external costs associated with the consumption of alcoholic beverages are so significant as to justify substantial excise taxes on those beverages others counter that a tax on alcohol would reduce consumption indiscriminately and therefore reduce the satisfaction experienced by millions of sensible drinkers without necessarily reducing the harm caused by a few excessive drinkers 2 this paper presents and applies a framework for evaluating these two views of the efficiency welfare effects of alcohol taxes determining the efficiency implications of alcohol taxes is complicated by the question of whether and how much abusers especially alcoholics benefit from alcohol consumption standard welfare theory assumes that all consumers of alcohol enjoy positive net benefits consumer surplus however it is possible that alcoholics over consume in the sense that consumer surplus from their

alternative panel estimates of alcohol demand taxation and the business cycle this paper uses a new technique of estimating dynamic heterogeneous panels developed by pesaran shin and smith 1999 on state level alcohol consumption as a function of income taxes and cyclical variables pooled mean group pmg estimators provide an alternative to extremes of pooling the data assuming slope homogeneity and estimating individual states assuming complete heterogeneity postsample tests indicate that a conventional fixed effects model outperforms both the pmg estimator and individual state estimators despite the heterogeneity of the sample current levels of taxation appear to have little effect on alcohol consumption and alcohol is found to be a procyclical good

rational habit formation abstract this paper discusses consumer demand under rational habit formation if consumer tastes change endogenously through habit stocks depending on past consumption the rational consumer will make allowance of the future habit forming effects of current consumption a model with rational habit formation is made formally equivalent to an intertemporal consumer model without habit formation by redefining the cost of consumption and wealth the cost of consumption is obtained by adding the cost of future induced consumption to the rental price of the commodity the extended wealth concept is obtained by subtracting the cost of the initial stocks of habits and the cost of future physically necessary consumption from wealth the paper also investigates the implication of rational habit formation for constructing one period cost of living indices

a dynamic demand model for liquor the case for pooling this paper estimates a dynamic demand model for liquor in the united states using panel data from 43 states because of taste changes over time and between states in liquor consumption purely time series or cross sectional studies do not elicit reliable price elasticity estimates this study makes the case for pooling and shows how one can control for individual state effects and endogeneity of the regressors using estimators suited for a dynamic demand model our results indicate that the long run price elasticity is in the 0 7 range the findings also support strong habit persistence a small positive income elasticity and very weak evidence of bootlegging from adjoining states the magnitude of the long run price effect suggests that sin taxes can serve not only as an important income source but also as a significant deterrent effect copyright 1995 by mit press

the duration of the smoking habit i introduction most smokers smoke out of habit once the habit is ended many of smoking s most harmful effects decline rather quickly preventing and ending cigarette addiction is therefore the straightest path toward preventing the health damage done by cigarette smoking consequently the related questions of why people start smoking and why they quit are central to formulating and evaluating effective antismoking policies duration or hazard models are designed to measure the probability of transition between states and are thus ideal for investigating the structural determinants of the transition between addiction and non addiction nevertheless most previous work in the economics literature uses the aggregate smoking participation rate defined as the percentage of people who currently smoke or an individual s probability of participation rather than a hazard rate to measure the attractiveness of habitual smoking this paper models the hazard rates of both starting and quitting the cigarette smoking habit the starting hazard rate is the probability that an individual will start smoking in a given time period conditional on being a nonsmoker until then the quitting hazard rate is the probability of quitting smoking in a given time period conditional on being a smoker since the starting date both of these rates should rise and fall in response to changes in the attractiveness of smoking the two rates will respond differently to different stimuli since the starting hazard reflects the point of view of nonsmokers and the quitting hazard reflects the point of view of smokers hazard or duration models possess several advantages over smoking participation models most obviously smoking participation rates cannot directly distinguish between increased starting rates and decreased quitting rates but the hazard models can also in a participation rate model it is difficult to control for the effect of the duration of the habit whereas duration models are designed specifically to allow for and measure the dependence of the hazard rate on duration another advantage is that the participation rate at any one time will oversample the number of long term smokers relative to those who had a short term habit whereas a duration model is designed to avoid this source of bias one drawback however is that because of their inherent panel nature the data requirements of duration models are somewhat more difficult to satisfy as shall be seen the only previous work in the economics literature that estimates the hazard rate of starting smoking is douglas and hariharan 1994 my paper improves upon douglas and hariharan in at least three important ways first it estimates the hazard rate of quitting smoking as well as that of starting second it takes into account variation in state level regulation third its time varying covariate model allows hazard rates to respond dynamically to changes in cigarette price regulation and information variables the use of time varying covariates is important because it brings the empirical model into much closer accord with theory the decision whether or not to start or quit smoking is an ongoing decision made one day at a time on the basis of current information the hazard of starting is greatest when the cost of the habit appears lowest and its benefit appears highest this comparison of cost and benefit changes through time as price information income and life cycle variables change while douglas and hariharan 1994 used price information from the potential smoker s most vulnerable age on the theory that its marginal effect is greatest at that time the model used in this paper allows each individual s hazard rate to respond to changes in price and public information as they occur the leading theoretical model of the decision to smoke is the rational addiction model of becker and murphy 1988 which assumes that consumers of addictive goods begin smoking only after fully weighing the costs and benefits of the habit

alcoholism work and income this article reports on an empirical analysis of the relationships between alcoholism and income and working we show that the relationships between alcoholism and labor market success have important age or life cycle dimensions we present evidence that alcoholism may affect income more by restricting labor market participation than by affecting the wages of workers finally we demonstrate that the effects of alcoholism on earnings depend on the extent to which one controls for other covariates associated with alcoholism as such we suggest that there may be important indirect as well as direct effects of alcoholism on labor market success

australian beer wars and pub demand how vertical restraints improved the drinking experience recently australia s two largest brewers carlton and united breweries and lion nathan have been aggressively competing for market share in the state of victoria among other strategies the two breweries have implemented vertical restraints in the form of extensive agreements with retailers and the outright purchase of pubs a key outcome of these purchases and agreements is the renovation of many pubs as brewers attempt to attract increasingly sophisticated drinkers this paper attempts to quantify the value of these renovations and measure their associated impact on consumers relying on insights from the hedonic literature a simple but novel approach is used to estimate the implicit price of the pub environment and the effects of renovations on that price

tax incidence with strategic firms in the soft drink market abstract because soft drink sd consumption is considered to be a contributor to the epidemic of obesity there is a growing interest in evaluating the impact on sd consumption of alternative tax policies in this paper we propose a methodology to evaluate the impact of taxation of a food market taking into account the strategic price response of both manufacturers and retailers we apply this methodology to the french sd market and simulate the impacts of ad valorem and excise taxes we find that firms behave differently when facing an ad valorem tax or an excise tax an excise tax is overshifted to consumer prices while an ad valorem tax is undershifted to consumer prices we find that an excise tax based on the sugar content of sd is the most effective at reducing sd consumption our results also indicate that ignoring strategic pricing by firms leads to misestimations of the impact of taxation by between 15 and 40 depending on the products and the tax implemented in the short term that is ignoring positive long term health effects a 9 cents l excise tax has a small negative welfare effect about 1 person year

evaluating dispatchability features in competitive bidding in power systems competitive bidding for electric generating capacity is beginning to emphasize dispatchability the authors examine various aspects of the evaluation problem facing electric utilities recent private power contracts are used to illustrate the range and limits upon flexibility that are being offered only detailed production simulation models can capture the cost implications of the features being offered the value of the dispatchability was found to increase with the variable cost of operation the most important cost found was associated with projects offering only limited curtailment procedures for incorporating subtle dispatch effects in a broader evaluation framework are identified

beyond kyoto backstop technologies and endogenous prices on co2 permits and fossil fuels this paper analyses the markets for fossil fuels given that the limits the kyoto protocol sets on co2 emissions from annex b countries extend beyond 2008 2012 a forward looking model with endogenous prices for fossil fuels is applied under different assumptions concerning the technological progress for a carbon free backstop technology both the time profile of the international permit price needed for the kyoto forever targets as well as the implications through reduced demand and lower producer prices for fossil fuels are calculated the permit price has to rise at least up to 2030 in order to fulfil the emission targets from then on the necessary permit price shows different future developments dependent on when the backstop technology starts to replace oil since changes in the availability of the backstop technology shift the time profile of the permit price the loss of petroleum wealth for oil and gas producers varies between the scenarios but is never more than 20 findings indicate that the

employment wages and alcohol consumption in russia 1 introductionconcerns regarding the relationship between alcohol consumption and labor market productivity are well grounded if problem drinking or alcoholism is considered a disease then it may have depressant effects on labor market productivity causing reductions in employment earnings and other labor market outcomes mullahy and sindelar 1993 1996 kenkel and ribar 1994 however there is a medical literature that documents a u shaped relationship between alcohol consumption and the risk of cardiovascular disease according to this literature moderate drinkers have a lower risk of cardiovascular disease than do either abstainers or heavy drinkers beaglehole and jackson 1992 doll et al 1994 consistent with this evidence several economists have found a positive association between moderate drinking and earnings berger and leigh 1988 french and zarkin 1995 heien 1996 hamilton and hamilton 1997 zarkin et al 1998 macdonald and shields 2001 this article investigates the impact of alcohol consumption on employment and wages in russia the primary contributions of the article are twofold first it enhances the economic literature on the relationship between alcohol consumption and labor market behavior by using data from a longitudinal survey the use of a longitudinal data set enables the estimation of a fixed effects model which helps avoid the potential bias caused by unobserved individual factors not captured in cross sectional models the use of a fixed effects model is an important extension to the literature because the data sets used in previous studies are cross sectional and usually lack adequate variables that could serve as identifying instruments to control for the endogeneity of alcohol consumption 1 furthermore the richness of the data set used in this article allows for the application of three alternative measures of alcohol consumption in the empirical analysis this is important because the relationship between alcohol consumption and labor market outcomes may be sensitive to the alcohol measure that is used the second notable contribution of this article is that it provides the first empirical evidence on the association between alcohol consumption and labor market outcomes in russia excessive alcohol consumption is a widespread problem in russia where per capita alcohol consumption is around 14 liters per year the world health organization who considers 8 liters to be a sign that a country has a critical consumption level for health problems quinn judge 1997 furthermore the dramatic fluctuations in mortality rates experienced in russia over the past 15 years have generated considerable attention to the potential effect of alcohol consumption on the overall health of the russian population it is important to investigate how labor market outcomes would be affected by alcohol consumption in a country which demonstrates such dramatic fluctuations in alcohol consumption and mortality consistent with the previous studies cross sectional results generally support the hypothesis of an inverse u shaped relationship between alcohol consumption and wages and employment results from the fixed effect models are found to be quite different from those of cross sectional models the positive effect of alcohol consumption on employment disappears for both males and females once the individual fixed effects are controlled for the results of the wage model lend support to a small and linear return to alcohol consumption but the effects are significant only at the 10 level the fixed effects estimates are smaller in magnitude and estimated with less precision compared with cross sectional estimates section 2 reviews the previous literature section 3 discusses the conceptual issues and empirical strategy section 4 introduces the data set section 5 provides a discussion of the results and sensitivity analyses section 6 concludes the article

on the existence of balanced growth equilibrium the authors characterize the class of dynamic models that allow for the most commonly used types of sustained economic growth balanced and asymptotically balanced they show that under a constant returns to scale technology asymptotically constant discount rate and asymptotically constant elasticity of marginal felicity are not only necessary but also sufficient conditions for the existence of a n asymptotically balanced growth equilibrium path the authors provide examples of recursive utility models that accept a n asymptotically balanced growth equilibrium and discuss their implications on cross country differences in growth rates as well as on savings behavior and wealth distribution copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

comparing specific and ad valorem pigouvian taxes and output quotas when the production or use of a good creates an external cost an unregulated market produces a socially inefficient quantity of output one remedy for this inefficiency is to impose a pigouvian tax equal to the marginal external damage associated with the good in many circumstances privately optimizing agents facing a pigouvian tax make decisions that are consistent with the maximization of social welfare

advertising price and welfare evidence from the u s brewing industry the welfare effect of advertising has been a subject of controversy among economists for some time one obvious concern is simply the cost of advertising in 1990 for example americans spent 130 1 billion on advertising to put this figure into perspective this amounted to 523 per capita 2 35 percent of gross national product and roughly 80 percent of the national deficit 1 much of the early debate regarding the social desirability of advertising stems from different preconceptions regarding its purpose 13 14 8 49 for example according to the kaldor 29 hypothesis advertising is primarily persuasive or deceptive in nature it changes consumer preferences creates brand loyalty and persuades consumers to favor commodities that they did not previously desire an opinion survey by bauer and greyser 5 indicates that consumers believe that much of advertising is persuasive and greyser and reece 27 158 find that 85 percent of the over 2 700 harvard business review subscribers surveyed believe that advertising persuades people to buy things they do not need if advertising is purely deceptive then it can be classified as a bad and reduces welfare

the demand for alcohol the differential response to price although several studies indicate that drinking is responsive to price little work has focused on whether prices have a differential effect on light moderate or heavy drinking this study examines the price responsiveness of the demand for alcohol whether heavy drinkers are less sensitive to price than light or moderate drinkers the study uses data on alcohol consumption on the 1983 national health interview survey the results indicate that both light and heavy drinkers are much less price elastic than moderate drinkers further we cannot reject the hypothesis that the very heaviest drinkers have perfectly price inelastic demands
