bookbuilding and strategic allocation in the bookbuilding procedure an investment banker solicits bids for shares from institutional investors prior to pricing an equity issue the banker then prices the issue and allocates shares at his discretion to the investors we examine the books for 39 international equity issues we find that the investment banker awards more shares to bidders who provide information in their bids regular investors receive favorable allocations especially when the issue is heavily oversubscribed the investment banker also favors revised bids and domestic investors investment banks commonly build a book before pricing an equity issue in the united states it has been standard practice for a number of years in many other countries where fixed price offerings were traditionally used the bookbuilding procedure is becoming increasingly common especially for international equity issues 1 under the formal bookbuilding procedure the investment banker solicits indications of interest from institutional investors such indications consist of a bid for a quantity of shares and might include a maximum price i e a limit price or other details the investment banker uses the information to construct a demand curve the issue price is not set according to any explicit rule but rather based on the banker s interpretation of investors indications of interest he generally sets the price at a level at which demand exceeds supply and then allocates shares to the bidders at his discretion thus the

when do high stock returns trigger equity issues abstract one of the most prominent stylized facts in corporate finance is that equity issues tend to follow periods of high stock returns we document that firms exhibit such timing behavior only in response to high returns that coincide with strong institutional investor demand when not accompanied by institutional purchases stock price increases have little impact on the likelihood of equity issuance the results highlight the importance of market reception for the timing of equity issues

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

economic efficiency effects of alternative policies for reducing waste disposal abstract reducing the amount of municipal solid waste that is disposed of has become an important policy goal previous research argued that a virgin material tax offered an efficient method of meeting this goal and it continues to be considered as a policy option today this paper demonstrates however that a virgin material tax is not an efficient method of reducing waste but that an alternative policy a combined disposal tax and reuse subsidy is the combined disposal tax and reuse subsidy is theoretically consistent with unit based household charges for waste disposal but may have advantages in some situations

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

elite law firms in the ipo market abstract ipos with underwriters that retain an elite law firm exhibit a lower average first day return this empirical pattern remains after controlling for an extensive set of proxies associated with existing explanations of ipo initial returns we rationalize this finding with a pre ipo pricing model in which underwriters convey their lack of conflicts of interest to the issuer by engaging an elite law firm consistent with this selection channel and our model s predictions we find a lower incidence of elite law firm involvement and a larger difference in average first day return associated with elite law firms during the dot com period we document similar findings with respect to the dispersion of ipo first day returns and a pattern in the issuers re hiring decision of investment banks consistent with our theory

welfare implications of the interaction between habits and consumption externalities we analyze the welfare properties of the equilibrium path of a growth model where both habits and consumption externalities affect the utility of consumers our analysis highlights the crucial role played by complementarities between externalities and habits in order to generate an infficient dynamic equilibrium in particular we show that the competitive equilibrium is inefficient when consumption externalities and habit adjusted consumption are not perfect substitutes

allocation of initial public offerings and flipping activity abstract there is a general perception that the large trading volume in initial public offerings is mostly due to flippers that are allocated shares in the offering and immediately resell them on average however flipping accounts for only 19 of trading volume and 15 of shares offered during the first two days of trading institutions do more flipping than retail customers and hot ipos are flipped much more than cold ipos institutions do not quickly flip cold ipos to take advantage of price support activities by the underwriter explicit penalty bids are rarely assessed against flippers

the effect of income and food programs on dietary quality a seemingly unrelated regression analysis with error components this article employs new food guide pyramid servings data to measure how food intake is affected by income and two food programs the analysis uses a maximum likelihood estimator that combines the seemingly unrelated regression and one way error component models to account for two types of intrahousehold correlations participation in the food stamp program is associated with higher intake of meats added sugars and total fats participation in the special supplemental nutrition program for women infants and children is associated with lower intake of added sugars

the impact of obesity on wages abstract previous studies of the relationship between body weight and wages have found mixed results this paper uses a larger data set and several regres sion strategies in an attempt to generate more consistent estimates of the effect of weight on wages differences across gender race and ethnicity are explored this paperjnds that weight lowers wages for white females ols esti mates indicate that a difference in weight of two standard deviations roughly 65 pounds is associated with a difference in wages of 9 percent in absolute value this is equivalent to the wage effect of roughly one and a half years of education or three years of work experience negative cor relations between weight and wages observed for other gender ethnic groups appear to be due to unobserved heterogeneity i introduction several previous studies have found among females a negative cor relation between body weight and wages there exist three broad categories of ex planations for this finding the first explanation is that obesity lowers wages for example by lowering productivity or because of workplace discrimination the sec ond is that low wages cause obesity this would be true if poorer people consume

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

testing for forward looking behaviour evidence from the enactment of smoking restrictions abstractthis paper develops a new test for forward looking behaviour based on the establishment of public smoking restrictions given that the announcement of these restrictions effectively increases the future cost of smoking we should expect forward looking smokers to curb their consumption before the restriction is effective due to complementarity between present and future consumption i perform the estimation using detailed high frequency household level purchase data the results provide evidence against the forward looking behaviour of smokers households do not reduce their cigarette purchases before announced public smoking restrictions are established they only do so once the restriction is in effect

on the dynamics of recycling and natural resources we study the dynamic impact of recycling through its effect on the production set of the economy and its relationship with natural resources the contribution of renewable and recyclable resources for sustainability is studied although in the short run recycling may alleviate resource scarcity in the long run it is not enough to compensate for the exhaustibility of non renewable resources and the possibility of obtaining non decreasing output paths crucially depends on the extent to which production rests on renewable resources furthermore recycling interacts with natural resource growth surprisingly not always favoring sustainability the production and recycling function is a generalization of the traditional production function providing an integrated view of regular production and recycling and representing the production set of the economy when a recycling technology is available

who leaves money on the table the role of founder identity in hong kong abstractthis study investigates the effect of corporate governance factors on the underpricing of initial public offerings ipos in hong kong and the results show that this effect is significant ipos are categorized into four subgroups based on the role of the founder 1 no founder firms companies with no specific founder 2 pure founder firms companies whose founder is neither the company s chairman of the board nor its ceo 3 founder chairman ceo firms companies whose founder is either the company s chairman of the board or its ceo and 4 founder chairman ceo firms companies whose founder is the chairman and ceo the results demonstrate a significant descending pattern for the underpricing level of the four subgroups which can be explained by the varying incentive and behaviour mechanisms that result from the various founder identities

a post consumer waste management model for determining optimal levels of recycling and landfilling the present study examines the optimal recycling rate for municipal solid waste first an optimal control model is developed to account for the physical costs of recycling the social costs of landfilling and consumers environmental preferences second an optimal solution is simulated using waste disposal data from the helsinki region in finland the benefits from recycling are included in the simulation using the results of a recent contingent valuation study the results of the present research suggest that mandates for achieving 50 recycling in municipalities are not far fetched and are both economically and environmentally justified

garbage recycling and illicit burning or dumping abstract with garbage and recycling as the only two disposal options we confirm prior results that the optimal curbside fee for garbage collection equals the direct resource cost plus external environment cost when illicit burning or dumping is a third disposal option that cannot be taxed directly the optimal curbside tax on garbage changes sign the optimal fee structure is a deposit refund system a tax on all output plus a rebate on proper disposal through either recycling or garbage collection the output tax helps achieve the first best allocation even though it affects the choice between consumption and untaxed leisure

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

why do ipo underwriters allocate extra shares when they expect to buy them back i argue that overallocation is used as a marketing strategy to increase the offer price and aftermarket price of an initial public offering ipo i show that when there is weak demand it can be optimal for the underwriter to oversell an issue and take a naked short position the issuing firm benefits from a higher expected offer price this is in spite of the fact that in equilibrium allocating more shares when there is weak demand requires greater underpricing when there is strong demand

the economic causes of obesity a survey abstract obesity rates have increased dramatically over the last 30 years rising obesity has developed into a considerable worldwide public health problem with significant economic and social consequences accordingly obesity has become a subject of economic research this paper provides a broad survey of the recent and growing economic literature on the causes of obesity the literature both theoretical and empirical overall aims to explain the rising obesity trend and to identify the factors that contribute to obesity also surveyed are non economic causes and consequences of obesity and the interconnection with economic influences an understanding of the causes of obesity allows policies to be considered that might stem the global increase in obesity

asymmetric information and intermediation chains we propose a parsimonious model of bilateral trade under asymmetric information to shed light on the prevalence of intermediation chains that stand between buyers and sellers in many decentralized markets our model features a classic problem in economics where an agent uses his market power to inefficiently screen a privately informed counterparty paradoxically involving moderately informed intermediaries also endowed with market power can improve trade efficiency long intermediation chains in which each trader s information set is similar to those of his direct counterparties limit traders incentives to post prices that reduce trade volume and jeopardize gains to trade

price clustering of chinese ipos the impact of regulation cultural factors and negotiation abstractduring june 2009 may 2012 the china securities regulatory commission csrc suspended window guidance that limits issue prices using this regime change as a natural experiment we test th

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

on the second best policy of household s waste recycling this study analyzes the second best household s waste recycling policy if we assume the first best economy with no illegal disposal or transaction costs then unit pricing an advance disposal fee and a recycling subsidy are required in order to achieve the social optimum such that both the sum of unit pricing and an advance disposal fee and the sum of unit pricing and a recycling subsidy are equal to the marginal disposal cost furthermore the first best outcome can also be obtained by a producer take back requirement system in the real economy however various factors prevent the first best optimal outcome in this study we consider two factors one being the transaction cost associated with a recycling subsidy or refund and the other being illegal disposal by the consumer if a recycling subsidy or a deposit refund system is adopted a transaction cost associated with it will be generated alternatively if unit pricing is adopted some of the consumed goods may be disposed of illegally we show the complete trade off between unit pricing and a recycling subsidy in other words we can not adopt unit pricing and a recycling subsidy simultaneously as a result there are three candidates for the second best policy unit pricing with an advance disposal fee a deposit refund system and a producer take back requirement system which of these three policies is the second best policy will depend on the relative magnitude of the price of a recycled good and the marginal transaction cost associated with a recycling subsidy or the refund in a deposit refund system generally if the price of a recycled good is positive and the marginal transaction cost is relatively high unit pricing with an advance disposal fee is the second best policy however where the price of a recycled good is negative and the marginal transaction cost is relatively high a producer take back requirement system is the second best policy further where the marginal transaction cost is relatively low a deposit refund system is the second best policy regardless of whether the price of a recycled good is positive or negative

a comparison of public policies for lead recycling policies that encourage recycling may be used to reduce environmental costs from waste disposal because direct restrictions on disposal are difficult to enforce four recycling policies have been advanced i taxes on the use of virgin materials ii deposit refund programs iii subsidies to recycled material production and iv recycled content standards in this article i analyze the structure of these policies and their cost effectiveness in achieving reductions in disposal i then examine the policies in the empirical context of the recycling of lead from automobile batteries in order to calculate the effects of recycling programs i estimate the elasticities for primary and secondary lead supply and demand my results suggest that price based policy mechanisms can be successful in increasing lead recovery and that the difference in efficiency between the four approaches is similar

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

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

on the microeconomics of food and malnutrition under endogenous discounting abstract this paper explores the microeconomics and dynamics of food and nutrition it examines the linkages between malnutrition and the incentive to invest and accumulate capital the analysis focuses on a dynamic model where preferences about the future depend on nutrition and health situations of malnutrition cover both ends of the spectrum from nutrient deficiency to obesity the model involves preferences that are not time additive and exhibit endogenous discounting this provides a framework to investigate the factors affecting consumption and investment behavior the adverse investment incentives of malnutrition are examined

are wages habit forming evidence from micro data although utility functions play a central role in economics the axiom that utility depends only on the absolute levels of its arguments is rarely tested this paper uses panel data on 2000 british employees who remain with the same employer and who are not promoted from one wave to the next it is shown that one important measure of well being overall job satisfaction is strongly positively correlated with the change in the worker s pay between waves but is unrelated to the current level of pay empirical tests suggest that a reference dependent satisfaction function where individual well being depends on current pay relative to past pay is more consistent with these regression results than are productivity or agency explanations of increasing wage profiles some evidence is presented of greater job satisfaction effects of pay rises for lower paid less well educated and younger workers these results provide some micro evidence consistent with the theory widespread in social science of habituation individuals may become used to any given level of consumption or income as such they tie in with the finding that a country s well being as measured by the average happiness of its citizens is only weakly correlated with its per capita gnp

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

junk food home cooking physical activity and obesity the effect of the fat tax and the thin subsidy abstract in an effort to reduce the growing prevalence of obesity a tax on junk foods known as fat tax has been proposed the revenue from which could be used to finance a thin subsidy for healthy foods or exercising equipment the present paper addresses the fat tax and thin subsidy within a food intake rational choice model assuming that healthy meals are cooked at home with purchased ingredients and time input the paper examines the effects on obesity of a tax on junk food meals and a subsidy to cooking ingredients distinguishing between a weight conscious and a non weight conscious individual and between a weight conscious individual who is physically active and physically inactive the results show that for a non weight conscious individual a fat tax will unambiguously reduce obesity whereas a thin subsidy may increase obesity however for a weight conscious individual particularly one who is physically active even a fat tax may increase obesity as it may reduce not just the consumption of junk food but also the time devoted to physical activity the paper explores conditions under which obesity will rise fall or remain intact following the introduction of a fat tax or a thin subsidy

a cue theory of consumption psychological experiments demonstrate that repeated pairings of a cue and a consumption good eventually create cue based complementarities the presence of the cue raises the marginal utility derived from consumption in this paper such dynamic preferences are embedded in a rational choice model behavior that arises from this model is characterized by endogenous cue sensitivities costly cue management commitment and cue based spikes in impatience the model is used to understand addictive habit forming behaviors and marketing the model explains why preferences change rapidly from moment to moment why temptations should sometimes be avoided and how firms package and position goods

product design and efficient management of recycling and waste treatment abstract using a general equilibrium model where material is first extracted then used for producing a consumption good recycled and finally treated to reduce environmental damage we study efficiency restoring policies when one or more of the constituent markets are inactive the material is modeled as being embodied in the output and forms an important aspect of green product design if all markets for embodied material per unit output fail and if recycling benefit exceeds environmental damage the policy instruments needed for green design are a tax on the consumption good supply and a subsidy on the demand for material input

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

disclosure and agency conflict evidence from mutual fund commission bundling abstract this study provides empirical evidence on the role of disclosure in resolving agency conflicts in delegated investment management for certain expenditures fund managers have alternative means of payment which differ greatly in their opacity payments can be expensed relatively transparent or bundled with brokerage commissions relatively opaque we find that the return impact of opaque payments is significantly more negative than that of transparent payments moreover we find a differential flow reaction that confirms the opacity of commission bundling collectively our results demonstrate the importance of transparency in addressing agency costs of delegated investment management

life cycle consumption of a harmful and addictive good david goldbaum this article demonstrates that the endogenous desire to quit smoking can result from a rational consumption path chosen at the time the consumer begins smoking this result is obtained without relying on hidden costs or unknown preferences a finite lived agent chooses a path of consumption of a harmful and addictive good to maximize present discounted utility the consumer chooses his consumption rate to account for the future health consequence of smoking and the withdrawal costs of quitting a consumer may choose to smoke even if it means a lowered utility level for the majority of the time spent smoking jel d91 c61 i12 i introduction some of what we consume for pleasure can be harmful economists assume that consumers take measure of the potential harm and balance it against the pleasure derived from consumption when both the pleasure and the harm occur at the time of consumption the decision is straightforward some goods though impose a cost borne at some future date requiring intertemporal planning these present a greater challenge to the consumer and to the economist trying to explain the consumer s behavior at times observed behavior implores us to question whether the consumer is properly weighing the costs and benefits in a manner that maximizes his or her utility theoretically for each item under consideration the rational consumer properly balances the lifetime benefits derived from the consumption against the lifetime costs some observed behavior seems to contradict this rational approach to consumption in particular it is common for people to begin smoking cigarettes during their youth only to endogenously make a decision to quit at a future date to integrate this behavior with rationality modelers have proposed hidden costs multiple selves changing preferences or other strategies that limit the decision making ability of the youth in all of these cases for some consumers the decision to smoke is a mistake made during youth that has to be reversed at some cost as a middle aged adult this article aims to demonstrate that a lifetime path of consumption in which a person consumes a harmful and addictive good while young and quits at some later date is a path that is perfectly consistent with rational behavior it is not necessary to assume that mid life quitters are displaying irrational or time inconsistent behavior if all information regarding a good s harmful properties is revealed some consumers will still choose a path that requires quitting mid life this paper primarily examines the consumption of cigarettes but also includes analysis of a nonaddictive unhealthy good both of these harmful goods provide the consumer with immediate pleasure but at the cost of decreasing life expectancy background becker and murphy 1988 bm introduced the concept of rational addiction the idea that addicts are forward looking rational consumers present consumption choices reflect not only current utility considerations and budget constraints but also incorporate the anticipated impact of present consumption on future utility and budget constraints bm examine the behavior response of addicts to exogenous shocks changes from a steady state including the desire to quit originate only from exogenous shocks such as a change in the relative price of the good or a revelation about the detrimental health consequences of the addictive good that alters the consumer s utility derived from consumption the model offers no mechanism by which smokers may choose to alter behavior endogenously in contrast to bm s smokers many of today s smokers appear to quit in absence of an external shock anyone who began smoking after 1966 has been subjected to the legislated health warnings appearing on cigarette packages since that time 1 antismoking messages in radio and television advertisements during the 1950s and 1960s also helped to make the health consequences of smoking common knowledge

what is sustainable development this paper introduces two axioms that capture the idea of sustainable development and characterizes the welfare criterion that they imply the axioms require that neither the present nor the future should play a dictatorial role in society s choices over time theorems 1 and 2 show there exist sustainable preferences which satisfy these axioms and provide a full characterization theorems 3 5 study a standard dynamical system representing the growth of a renewable resource economy give a turnpike theorem and exhibit the differences between sustainable optima and the ones according to discounted utilitarianism

the efficient ipo market hypothesis theory and evidence we derive the optimal underwriting method and the quantitative initial public offering ipo pricing rule that this method implies in a market with informational frictions consisting of fully rational banks issuers and investors in an efficient ipo market an issuer s expected initial return will be determined entirely by the combination of this pricing rule and issuer fundamentals applying this rule we find that we can explain the quantitative magnitude of the principal aspects of the time series and cross sectional variation in ipo average initial returns we conclude that the ipo market is efficient

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

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

why don t issuers get upset about leaving money on the table in ipos one of the puzzles regarding initial public offerings ipos is that issuers rarely get upset about leaving substantial amounts of money on the table defined as the number of shares sold times the difference between the first day closing market price and the offer price the average ipo leaves 9 1 million on the table this number is approximately twice as large as the fees paid to investment bankers and represents a substantial indirect cost to the issuing firm we present a prospect theory model that focuses on the covariance of the money left on the table and wealth changes our reasoning also provides an explanation for a second puzzling pattern much more money is left on the table following recent market rises than after market falls this results in an explanation of hot issue markets we also offer a new explanation for why ipos are underpriced copyright 2002 oxford university press

natural resources national accounting and economic depreciation abstract the current value hamiltonian in an aggregate optimal growth problem with heterogeneous capital stocks including exhaustible renewable and environmental stocks is the nnp function routine substitutions reveal that the using up of natural resource stocks is representable as easy to interpret economic depreciation magnitudes we obtain true nnp inclusive of natural resource stock diminution implications for actual national accounting practices are also discussed

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

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

supersizing supercenters the impact of walmart supercenters on body mass index and obesity abstract researchers have linked the rise in obesity to technological progress reducing the opportunity cost of food consumption and increasing the opportunity cost of physical activity we examine this hypothesis in the context of walmart supercenters whose advancements in retail logistics have translated to substantial reductions in the prices of food and other consumer goods using data from the behavioral risk factor surveillance system matched with walmart supercenter entry dates and locations we examine the effects of supercenters on body mass index bmi and obesity we account for the endogeneity of walmart supercenter locations with an instrumental variables approach that exploits the unique geographical pattern of supercenter expansion around walmart s headquarters in bentonville arkansas an additional supercenter per 100 000 residents increases average bmi by 0 24 units and the obesity rate by 2 3 points these results imply that the proliferation of walmart supercenters explains 10 5 of the rise in obesity since the late 1980s but the resulting increase in medical expenditures offsets only a small portion of consumers savings from shopping at supercenters

the causal link between financial incentives and weight loss an evidence based survey of the literature obesity and overweight are linked to diseases that cost society a significant amount of resources while behavior modification can reduce the problem instigating such lifestyle changes is an uneasy task one potential way to reduce the problem is through the use of financial incentives in this survey we review the available evidence properly emphasizing studies that credibly yield meaningful estimates of the effect of financial incentives on weight loss we find that the scientific literature on the subject has not yet satisfactorily settled whether such a mechanism is effective at eliciting the desired behavioral and health outcomes we therefore advocate a rigorous large scale randomized experiment to provide reliable estimates of the effect

can downstream waste disposal policies encourage upstream design for environment design for environment takes place when firms explicitly incorporate environmental issues in their product design and manufacturing decisions joseph fiksel 1996 to reduce waste associated with consumer products for example firms can reduce product weight including the amount of packaging that comes with a product and make products easier and less costly to recycle the latter can be accomplished by changing the type of material used in a product avoiding mixing of materials in a single product coding and labeling when different materials are used and designing for ease of disassembly u s congress office of technology assessment 1992 fiksel 1996 an important debate centers around the question of whether design for environment dfe needs to be explicitly targeted using policy instruments focused upstream on producers or whether downstream instruments send sufficient signals back upstream one important downstream instrument is a disposal fee i e charging households a price per pound per bag or per can for their trash many observers feel that downstream instruments do not send appropriate signals back upstream some economists and others have suggested on the other hand that disposal fees can in theory send signals upstream to producers karen palmer and walls 1998 we find that disposal fees provide incentives for efficient dfe only when there is a fully functioning recycling market i e only when recyclers pay households a price for each of their recyclable items and that price varies with the degree of product recyclability in the real world transactions costs of paying households for each individual item recycled would be prohibitively high in a more realistic setting in which households may place some items in a recycling bin but are not paid for doing so a disposal fee by itself will not yield a social optimum it encourages households to place items in the bin but all items allowed in the bin are of equal value to the household i e there is no reason to prefer an easily recyclable aluminum can to a difficult to recycle plastic milk jug this means that there is no signal to producers to make products more recyclable if the government can set product taxes that vary with product recyclability the social optimum can be restored but this option is not practicable 2 we argue that the infeasibility of i paying households for recycling and ii taxing products according to their recyclability means that a first best outcome is no longer attainable instead we set up a constrained second best optimum and solve for policy instruments that achieve this outcome we find that a disposal school of economics and finance victoria university of wellington wellington new zealand walls is also a university fellow with resources for the future washington dc the helpful comments of karen palmer don fullerton and hilary sigman are greatlv appreciated 1 manufacturer take back requirements such as germany s well known packaging take back law were developed at least in part as a way to encourage dfe see www oecd org env epr index htm for updates from a series of oecd workshops held in 1997 1999 on the broader topic of extended producer responsibility in practice individual german producers do not actually take back their own products at end of life they have formed a consortium that arranges to collect members waste from households marked with a green dot and recycle it we do not address take back mandates in this paper 2 in calcott and walls 1999 we derive these taxes don fullerton and wenbo wu 1998 show that a direct subsidy to recyclability combined with other instruments can yield a social optimum this subsidy depends on production function parameters thus if firms differ the subsidy would vary across firms more i mportantly observing and measuring recyclability to determine subsidy payments would be virtually impossible

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

are ipo allocations for sale evidence from mutual funds combining data on brokerage commissions that mutual fund families paid for trade execution between 1996 and 1999 with data on mutual fund holdings of initial public offerings ipos i document a robust positive correlation between commissions paid to lead underwriters and reported holdings of the ipos they underwrite moreover i find that the correlation is limited to ipos with nonnegative first day returns and strongest for ipos that occur shortly before mutual funds report their holdings when the noise introduced by flipping is smallest overall the evidence suggests that business relationships with lead underwriters increase investor access to underpriced ipos during the hot initial public offering market of the late 1990s the typical initial public offering ipo was significantly underpriced and oversubscribed and the first day returns earned by investors in these ipos received considerable public attention 1 the source of these first day returns and related questions

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

ipo pricing and share allocation the importance of being ignorant since an underwriter sets an ipo s offer price without knowing its market value investors can acquire information about its value and avoid overpriced deals lemon dodge to mitigate this well known risk the bank enters into a repeat game with a coalition of investors who do not lemon dodge in exchange for on average under priced shares we i derive and test a quantitative ipo pricing rule showing that tech ipos were not excessively underpriced during the boom of the 1990s and ii analyzing a unique multibank data set find strong support for the conjecture that a bank preferentially allocates shares to its coalition do not approve of anything that tampers with natural ignorance igno rance is like a delicate exotic fruit touch it and the bloom is gone

schooling health knowledge and obesity the connection between schooling and health is well documented an important empirical issue that needs to be examined however is whether schooling s effects are due to individual health knowledge differences this empirical study examines this issue with an increasingly important health indicator obesity since provision of health knowledge is a major tool of public agencies promoting health this empirical study uses a new direct measure of health knowledge to test this hypothesis the results show that knowledge is inversely related to the probability that an individual is obese schooling s effects on relative weight and the probability of being obese are explained by differences in knowledge this result may imply that schooling s effect on the allocative efficiency of the household production of health is the main reason schooling is linked to health behaviour the result also may imply that the most effective method of health education is to highlight the disease element of poor dietary habits a

welfare enhancing technological change and the growth of obesity the theory explores how technological change can produce obesity as an unintended consequence of economic development which reduces food prices and the strenuousness of work the empirical analysis presents a specific example of how food price declines can improve health and well being even in a developed country

venture capitalist certification in initial public offerings this paper provides support for the certification role of venture capitalists in initial public offerings consistent with the certification hypothesis a comparison of venture capital backed ipos with a control sample of nonventure capital backed ipos from 1983 through 1987 matched as closely as possible by industry and offering size indicates that venture capital backing results in significantly lower initial returns and gross spreads in effect the presence of venture capitalists in the issuing firms serves to lower the total costs of going public and to maximize the net proceeds to the offering firm in addition we document that venture capitalists retain a significant portion of their holdings in the firm after the ipo the ability of third party specialists to certify the value of securities issued by relatively unknown firms in capital markets that are characterized by asymmetric information between corporate insiders and public investors has attracted much academic interest in recent years several authors including james 1990 blackwell marr and spivey 1990 and barry muscarella peavy and vetsuypens 1991 have developed and tested models based at least in part on the formal certification hypothesis presented in booth and smith 1986 a related body of work represented by deangelo 1981 beatty and ritter 1986 titman and trueman 1986 johnson and miller 1988 carter 1990 simon 1990 and carter and manaster 1990 has examined how investment bankers and auditors help resolve the asymmetric information inherent in the initial public offering ipo process in this paper we examine whether the presence of venture capitalists as investors in a firm going public can certify that the offering price of the issue reflects all available and relevant inside information we hypothesize that venture capitalists can perform this function that it will be an economically

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

optimal policies for solid waste disposal taxes subsidies and standards abstract pricing trash collection and disposal services can be politically unpopular and may lead to increased illegal disposal of trash several studies have shown that deposit refund systems can act like disposal charges without the illegal disposal problem and thus can generate an optimal amount of solid waste disposal we assess the efficiency implications of an alternative policy currently in use in some states in the u s and considered at the federal level recycled content standards these are requirements that a certain fraction of total material use in production be comprised of secondary materials we find that such standards by themselves cannot generate the optimal amount of disposal but must be combined with additional taxes on both the final product and other inputs to production moreover the information requirements for setting the optimal standards and accompanying taxes are high the deposit refund approach would be preferred in most cases

economic growth and transitions between renewable and nonrenewable energy resources abstract we study transitions between nonrenewable and renewable energy forms at different development stages of an economy it is shown that in the historical context the emphasis on energy production may evolve from renewables to nonrenewables and back to renewables typically both energy forms are used simultaneously along the equilibrium path nonrenewable resource consumption may increase and their price decrease an inverted u relation between carbon emissions and income level may follow even without environmental policy

an empirical analysis of milk addiction we show the estimable rational addiction model tends to yield spurious evidence in favor of the rational addiction hypothesis when aggregate data are used direct application of the canonical model yields results seemingly indicative that non addictive commodities such as milk eggs and oranges are rationally addictive monte carlo simulation demonstrates that such results are likely to obtain whenever the commodity under scrutiny exhibits high serial correlation or when even a small amount of the variation in prices is endogenous or when overidentified instrumental variables estimators are used or when commonly imposed restrictions are employed we conclude that time series data will often be insufficient to differentiate rational addiction from serial correlation in the consumption series
