government policy with time inconsistent voters behavioral economics presents a paternalistic rationale for benevolent government intervention this paper presents a model of public debt where voters have self control problems and attempt to commit using illiquid assets in equilibrium government accumulates debt to respond to individuals desire to undo their commitments which leads individuals to rebalance their portfolio in turn feeding into a demand for further debt accumulation as a consequence i large and distortionary government debt accumulation occurs and ii banning illiquid assets could improve individuals welfare these results offer a new rationale for balanced budget rules in constitutions to restrain governments responses to voters self control problems

addiction compulsion and the technology of consumption the consumption technology model of lancaster and becker is extended to include addictive activities assuming a utility function in which the individual places a premium on maintenance of self esteem the model generates empirically verified patterns of habituation withdrawal and the compulsive restarting of an abandoned habit it is then applied to the analysis of public policies toward drug abuse their frequent ineffectiveness is shown to result from an unwarranted emphasis on deterring the addictive activity rather than on encouraging atceptable behavior

optimality and monetary equilibria in stationary overlapping generations models with long lived agents growth versus discounting abstract this paper studies the relationship between the existence and optimality of a monetary steady state and the nonoptimality of nonmonetary steady states we construct a sequence of stationary overlapping generations economies with longer and longer lived generations in which all agents maximize a discounted sum of utilities with a common discount rate under some assumptions the following result is established if the discount rate is greater less than the population growth rate then eventually every nonmonetary steady state is optimal nonoptimal and a monetary steady state does not exist exists and is optimal

fiscal policy with agents differing in altruism and ability this paper presents an overlapping generations model of growth with individuals differing in productivity and altruism within such a model wealth is entirely held in the steady state by the families with the highest degree of altruism we then look at the macroeconomic and distributive effects of three fiscal policies public debt pay as you go social security and estate taxation under plausible assumption we show that both public debt and social security are neutral a la ricardo but increase inequality we also show that a estate taxation can be pareto worsening even though it can foster income equality

what price drug use the contribution of economics to an evidence based drugs policy abstract this paper presents a review of the recent economics literature in the area of illicit drug use particular attention is paid to the economics of addiction and the rational addiction model the welfare economics framework for analysing the social costs of drug use and the attempts that have been made by economists to evaluate recent or proposed policy interventions a dominant theme in this review is the problem of poor data availability this is particularly true when it comes to implementing the rational addiction model but it is also apparent in the literature on estimating the costs of illicit drug use to society as a whole one of the main conclusions of this review is that until recently public policy has not been particularly influenced by research carried out by economists it is not clear whether this is because economists have had to grapple with inadequate data and hence their conclusions are couched in uncertainty or whether it is because drugs researchers have assumed a very limited role for economists in their analysis

a fractionally cointegrated var analysis of economic voting and political support we use a fractionally cointegrated vector autoregressive model to examine the relationship between canadian political support and macroeconomic conditions this model is well suited for the analysis because it allows multiple fractional time series and admits simple asymptotic inference for the model parameters and tests of the hypotheses of interest in the long run equilibrium we find that support for the progressive conservative party was higher during periods of high interest rates and low unemployment while support for the liberal party was higher during periods of low interest rates and high unemployment we also test and reject the notion that party support is driven only by relative to the united states economic performance indeed our findings suggest that us macroeconomic variables do not enter the long run equilibrium of canadian economic voting political opinion poll support at all resume une application du modele vecteur autoregressif fractionnellement cointegre sur le vote economique et le support politique on utilise un modele du type vecteur autoregressif fractionnellement cointegre pour examiner la relation entre le support politique canadien et les conditions macroeconomiques le modele est bien adapte a l analyse parce qu il permet l usage de multiples series chronologiques fragmentees et une inference asymptotique simple des parametres du modele ainsi que des tests d hypothese pertinents en equilibre a long terme on decouvre que le support pour le parti progressiste conservateur a ete plus eleve au cours des periodes de hauts taux d interet et bas taux de chomage alors que le support pour le parti liberal a ete plus eleve au cours des periodes de bas taux d interet et de hauts taux de chomage on met au test l hypothese qu on rejette d ailleurs que la notion que le support politique est enclenche seulement par la performance economique du canada par rapport a celle des etats unis en fait les resultats suggerent que les variables macroeconomiques americaines n ont pas du tout d impact sur l equilibre a long terme du vote economique canadien support dans les sondages d opinion politique

the propensity for local traders in futures markets to ride losses evidence of irrational or rational behavior abstract behavioral studies of individual traders decisions indicate that the disposition effect the propensity of traders to ride losses yet realize gains is motivated by psychological rather than rational economic considerations consistent with previous studies by heisler rev futures markets 13 1994 793 odean j finance 53 1998 1775 and locke and mann do professional traders exhibit loss realization aversion working paper george washington university 2000 we find evidence of a disposition effect for both on floor professional futures traders locals and a matched sample of non local traders after controlling for potential differences in trader characteristics comparisons reveal a stronger disposition effect among locals than non local traders given that locals must trade profitably to survive it is improbable that they are more irrational in their loss riding than non locals to the contrary evidence is provided that paper losses for local traders are more likely than for non locals to become either realized or paper gains by the time of the next transaction this result is consistent with the hypothesis that locals by their presence on the trading floor have privileged albeit short lived information on order flow that allows them to form relatively accurate probability predictions of the direction and strength of short term market price shifts

fiscal interactions of central city and suburbs the case of zurich one possible explanation for the migration from the central city to fiscally independent suburbs is a lack of equivalence between taxation and perceived benefits from local public goods spill outs to suburbs add to this process and may lead to fiscal erosion of the central city piecemeal evidence is presented that this problem applies to the city of zurich various possible remedies are discussed one of which has been applied in zurich though not successfully it is shown theoretically and empirically why this failure occurred alternative countermeasures are suggested and an account of how zurich government officials reacted is supplied

rational addiction and the effect of price on consumption legalization of such substances as marijuana heroin and cocaine surely will reduce the prices of these harmful addictive drugs by the law of the downward sloping demand function their consumption will rise but by how much according to conventional wisdom the consumption of these illegal addictive substances is not responsive to price however conventional wisdom is contradicted by becker and murphy s 1988 theoretical model of rational addiction the becker murphy b m analysis implies that addictive substances are likely to be quite responsive to price in this paper we summarize b m s model of rational addiction and the empirical evidence in support of it we use the theory and evidence to draw highly tentative inferences concerning the effects of legalization of currently banned substances on consumption in the aggregate and for selected groups in the population addictive behavior is usually assumed to involve both reinforcement and tolerance reinforcement means that greater past consumption of addictive goods such as drugs or cigarettes increases the desire for present consumption but tolerance cautions that the utility from a given amount of consumption is lower when past consumption is greater these aspects of addictive behavior imply

spending cuts or tax increases the composition of fiscal adjustments as a signal abstract this paper shows that the composition of fiscal adjustments spending cuts versus tax increases serves as a signal of the government s degree of collusion with special interests the politico economic model of fiscal policies combining retrospective voting with common agency type lobbying presents undominated separating equilibria and intuitive pooling ones in both of which fiscal adjustments with sufficiently large spending cuts lead to incumbent reappointment whereas those with only tax increases lead to incumbent defeat these findings are consistent with the recent empirical evidence of voters behaving as fiscal conservatives the efficiency enhancing aspects of the signaling mechanism and the effects of imposing a deficit limit are also analyzed

international tax competition and the deficit bias i analyze the dynamic effects of tax competition on public budget deficits i find that stronger tax competition leads to a fiscal deficit bias at the early stages of financial liberalization when countries differ in terms of capital mobility further liberalization leads to external imbalances and diverging fiscal deficits while corporate tax rates converge consistent with theory i find that stronger tax competition increases deficits in a sample of oecd countries controlling for tax revenues and other standard determinants of fiscal deficits jel e62 f62

drug policy and federalism supply restricting drug policy is inefficient from an economic point of view but is nevertheless widely used this paper explains this phenomenon as individually rational behavior for local government because supply restriction gives addicts an incentive to migrate it has an external effect this effect makes a policy of supply restrictions individually rational but leads to socially wasteful competition between local governments in a federal system

voting on pensions a survey abstract the paper presents a nonexhaustive survey of the literature designed to explain emergence size and political sustainability of pay as you go pension systems it proposes a simple framework of analysis a small open two overlapping generation economy model around which some variants are displayed dictatorship of the median voter is assumed the text is organized to answer the following questions i do political equilibria with payg pension schemes exist ii why do they emerge iii what are the conditions for the participation constraint of the pension game to be verified and finally iv what is the size of the pension system chosen by the median voter and how is this size influenced by an exogenous e g demographic shock

the price elasticity of opium in taiwan 1914 1942 abstract between 1895 and 1945 the japanese colonial government virtually eliminated opium use in taiwan by licensing and treating existing users prohibiting sales to others and raising the price we evaluate these policies using a two part model to describe the fraction of the population using opium and consumption among users and the rational addiction model by becker et al 1991 we confirm that opium is addictive and find no evidence supporting the rational addiction hypothesis demand is price elastic with estimated short and long run demand elasticities of 0 48 and 1 38 these results have implications for control of other addictive substances

on barro s theorem of debt neutrality the irrelevance of net wealth the effects of national debt on real economic activity has been a recurring topic in the literature on macroeconomic policy analysis since the time of adam smith the problem is usually stated as follows for a given level of government spending is the economy sensitive to the financing mix between tax and debt historically attention has focused on the question of whether or not individuals perceive government bonds as net wealth the link between wealth and real activity being taken as given the main point of debate is well established the issue of bonds raises private assets by the full value of the bonds the corresponding tax liabilities for interest payments and retirement of the debt extend indefinitely into the future the perception of bonds as net wealth would then appear to depend on the length of the individual s optimization horizon the most recent contribution to this debate was made by robert barro 1974 in which he argued that despite the limitation of finite lives bonds will not be regarded as net wealth in a system characterized by operative intergenerational transfers the essence of his argument is that inclusion of a bequest motive effectively converts a finite horizon into an infinite one in that paper barro acknowledged a potential limitation on his proof of the neutrality result it was only valid for bonds that are redeemed at a known point in the future this limitation was raised again in a subsequent exchange with martin feldstein in which barro 1976 agreed that for a growing economy an increase in steady state per capita debt will generate net wealth if the rate of growth is greater than the interest rate however he argued that such a steadystate growth situation would not be consistent with rational utility maximizing behavior the main theme of this paper is that the literature has focused attention on the wrong question the real effects of national debt are independent of whether or not individuals perceive the debt as net wealth the correct question is whether or not changes in the level of debt force individuals into patterns of intertemporal consumption that they are unable to neutralize by adjustments in their portfolio behavior viewing neutrality in this light leads to some reinterpretation of the conditions under which neutrality is likely to hold my analysis starts where barro and feldstein leave off within the framework of the overlapping generations model with gift and bequest motives i show that steady state equilibrium growth is consistent with a growth rate in excess of the interest rate indeed without specific knowledge of the parameters of the economy there are no a priori grounds on which to expect any particular relationship between the growth and interest rates more importantly so long as it is valid to view the aggregate economy as behaving like a composite individual changes in the steady state level of government debt are neutral regardless of which relationship prevails provided one or the other of the intergenerational transfer motives is operative i will refer to this as the extended neutrality theorem section i presents an analysis of steadystate growth with gift and bequest behavior the steady state growth path is shown to lie above the golden rule solution if the gift

politico economic equilibrium and economic growth abstract we propose a notion of dynamic politico economic equilibrium which builds on two key assumptions policies are determined sequentially and agents are fully rational in their roles as both consumers and voters we examine a simple model of endogenous growth and infinitely lived agents where taxes on income are endogenous and where growth critically depends on the initial distribution of asset holdings we relate our equilibrium definition and results to existing literature on time consistency and on political economy and growth we show that our equilibria are time consistent and we argue that the choice of equilibrium concept might have important quantitative implications

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

aggregation of test statistics an evaluation of the evidence on contracting and size hypotheses abstract more powerful tests of a theory of choice of accounting methods and the effect of changes in these choices on equity values are provided the power increase comes from efficiently aggregating results across studies one conclusion is that at least six variables common to more than one study have explanatory power these variables are managerial compensation leverage size risk and constraints on interest coverage and dividends another conclusion is that the posterior probability that the theory taken as a whole has explanatory power is close to one this conclusion includes the effect of variables that only appear in one study

the political process and the use of debt financing by state governments empirical evidence offered in this study suggests that decisions by state government officials to effect debt financed spending depend in part on the state s gubernatorial election cycle more specifically the results reveal relative increases in state debt issues in anticipation of elections and furthermore they reveal that such increases are more significant for states characterized by high interparty political competition while theoretical limitations preclude a definitive explanation for these results the evidence is consistent with a view of state political markets where incumbent parties manipulate public policy so as to enhance the probability of success in pending elections this insight is significant in that it suggests a relationship between public policy decisions and election cycles in a context heretofore unexplored

prospect theory and the disposition effect this paper shows that prospect theory is unlikely to explain the disposition effect prospect theory predicts that the propensity to sell a stock declines as its price moves away from the purchase price in either direction trading data on the other hand show that the propensity to sell jumps at zero return but it is approximately constant over a wide range of losses and increasing or constant over a wide range of gains further the pattern of realized returns does not seem to stem from optimal after tax portfolio rebalancing a belief in mean reverting returns or investors acting on target prices

tax harmonization and tax competition in the european union lessons from switzerland abstract this paper presents empirical evidence on individual income tax competition in switzerland tax competition has some influence on the spread of people with high income over the cantons and it is partly capitalised in dwelling rents however it neither leads to a collapse of public good supply nor makes redistribution by the fiscal authorities impossible thus if tax competition works well in switzerland there is no reason why it should have disastrous effects in a future european union

information asymmetry and international strategic alliances abstract this paper examines how information asymmetry affects cross border strategic alliance formation by us firms over the period 2000 2008 we construct a measure information costs based on both geographical distance and the proportion of worldwide gdp the partner s home country represents consistent with our expectations we find an inverse association between information costs and cross border strategic alliances when considering the proportion of alliances formed with publicly quoted overseas partners we find this is unaffected by the level of information costs but rather the level of stock market development tax rate and general economic conditions information costs are however significantly negatively related to alliances with overseas private organizations our results offer clear support for the on going importance of information asymmetry in corporate decision making

bribery and public debt repudiation in cases where policy makers accept bribes offered by organised lobbies or interestedparties government decisions can be modelled as a first price menu auction in this paper we adaptthis structure to model debt repudiation we considera one period model in which two generations parents and children are present and debt titles are unevenlydistributed among parents the government can repaythe debt by a combination of taxes on the children sincome and on the outstanding debt we excludeintergenerational conflicts assuming that the parents and children s objective is to maximise the utility ofthe family in this perspective families make offersthat relate monetary contributions to the taxstructures chosen by the government on the hypothesisthat all interests are represented we obtain theresult that the government is indifferent to the taxstructure

the politics of intergenerational redistribution this paper studies the political economic equilibrium of a two period model with overlapping generations in each period the policy is chosen under majority rule by the generations currently alive the paper identifies a politically viable set of values for public debt any amount of debt within this set is fully repaid in equilibrium even without commitments by issuing debt within this set the first generation redistributes revenue in its favor and away from the second generation the paper characterizes the determinants of the equilibrium intergenerational redistribution and identifies a difference between debt and social security as instruments of redistribution

public investment and its effects on the burden of the public debt few problems in economics have been so thoroughly debated without being resolved as the question about whether the burden of the public debt is passed on to the future the key issue in the debate is whether taxation and debt are equivalent in their real effects as methods of raising public revenues the question in this form is an old one and both sides of the debate were eloquently discussed by ricardo 2 the purpose of this paper is to present a framework within which the choices facing the many different individuals in the society can be analyzed as is explained below the nature of the economy s adjustment to debt issue cannot be fully understood without first understanding that different individuals will adjust differently to the issuance of additional debt it is unlikely that a single paper could end a debate that is well over two centuries old hence our goal is more modestly to extend the framework of the debate adding some more realistic features to a barro like model illustrates that there are areas of commonality that unite both sides of the debate this study extends the current debate in two ways first it examines the intergenerational transfer of public sector wealth by including the effects of intergenerational bequests of assets in addition to the intergenerational transfer of debt after all when individuals consider the well being of their heirs they must consider the value of the assets that are passed from one generation to the next in addition to the stock of public debt 3 second it

marketmaker behavior in an auction market an analysis of scalpers in futures markets this paper focuses on the role of scalpers as marketmakers in the competitive auction of futures exchanges we use transactions data of a representative scalper to identify the source of scalper earnings we find that scalpers provide liquidity services to incoming market orders thereby facilitating commercial hedging scalper earnings are positively related to the bid asked spread and negatively related to the length of time a position is held futures trading is organized as an auction market with buyers and sellers confronting each other directly in a trading pit or ring on an exchange floor bids and offers are represented in the pit by open outcry trades are consummated throughout a trading session which usually last 4 to 6 hours whenever a bid is hit or an offer lifted by some other agent on the floor participants in futures markets include hedgers and speculators whose orders are called in and are represented by floor brokers in the pit in addition floor traders participate by bidding and offering for their own account some floor traders fall into the category of short term speculators day traders who prefer to trade for themselves rather than execute orders through a floor broker a somewhat more specialized group of floor traders are known as scalpers they are essentially marketmakers who quote bids and offers against which market orders can be executed they do not have an affirmative obligation to provide liquidity by quoting bids and offers but do so in the expectation of earning a return this paper examines the activities of scalpers on futures exchanges in order to identify the role of marketmakers in a freely competitive auction we focus on the nature of scalper decision making as well as on the contribution of scalpers to economic welfare one of our main concerns is with the source of a scalper s

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

self interest and public funding of education abstract the objective of this paper is to study whether publicly funded education can emerge as a political and economic equilibrium in an overlapping generations economy in which selfish agents vote for public funding of education the presence of complementarities between capital and labor in the production function implies that by improving the skills of next period s workers public funding of education increases the return on capital as a result savers will support a publicly financed education system in order to enhance their future income a version of the model calibrated using u s data generates large shares of gnp allocated to education hence the non altruistic incentive to support public education is quantitatively important

budget deficits and redistributive politics this paper proposes a new view of the forces in the political process that cause governments to accumulate debt the analysis builds on a model of redistributive politics that contrary to median voter models does not restrict the set of policies that politicians can propose i show that deficits occur even in an environment where voters and periods are homogeneous this is an environment where previous political theories of debt would predict budget balance in the model deficits are a way for candidates to better target promises to voters and are therefore used as tools of redistributive politics the main contribution of the analysis is to show that the same forces that push candidates to redistribute resources across voters to pursue political advantage are forces that generate budget deficits most countries have sizeable national debts indeed thinking of governments as debtors seems so customary that it feels awkward to talk about a national credit this suggests that there are systematic forces pushing governments to regularly borrow to cover the excess of spending over receipts at the same time a significant amount of government spending consists of transfers to special interest groups that are hard to justify on efficiency or equity grounds this paper presents a political economic model that suggests that these two phenomena are connected debt is at least in part caused by the fact that in order to get elected candidates need to appeal to groups of voters with promises of transfers debt allows candidates a finer control over the promises they make to these groups

a positive theory of fiscal deficits and government debt this paper considers an economy in which policymakers with different preferences alternate in office as a result of elections government debt is used strategically by each policymaker to influence the choices of his successors if different policymakers disagree about the desired composition of government spending between two public goods the economy exhibits a deficits bias that is debt accumulation is higher than it would be with a social planner the equilibrium level of debt is larger the larger is the degree of polarization between alternating governments and the less likely it is that the current government will be re elected

a political theory of government debt and deficits in a neo ricardian framework in the presence of different abilities and therefore different bequests some individuals are bequest constrained even in a neo ricardian world such individuals vote for taxes on future generations through the issuance of bonds thereby increasing their current consumption this produces some crowding out of capital reduces wage rates and increases the interest rate as a consequence even unconstrained individuals are no longer indifferent to the size of government debt the paper derives conditions that are conducive to larger debt and deficits when each of the living generations determines current taxes social security benefits and the national debt by majority rule copyright 1989 by american economic association

paradoxical effects of drug policy in a model with imperfect competition and switching costs this paper presents a stylized model of the market for hard drugs we assume that there is imperfect competition that the demand side is dominated by addicts and that the presence of switching costs leads to consumer loyalty drug policies affect the values of the parameters of the model including the degree of consumer loyalty and the static price elasticity of demand taking into account these effects it is shown that tough policies may lead to an increase in the marketing activities by suppliers and cause a long run increase in the number of addicts and total consumption

dynamic instability of a mixed city in the presence of neighborhood externalities it has been often asked whether a city currently accommodating a variety of economic social and racial groups will continue to be a mixed city or will become exclusively occupied by a single group particularly poor blacks with all other groups moving out of the city in the long run in order to answer this question properly it seems essential to develop a long run dynamic model of a city with emphasis on socioeconomic factors like neighborhood externalities within or among various groups of residents as well as spatial factors like the individual choice of residential space and location it might be safely said that in the literature the only theoretical work which employs a long run dynamic approach to this kind of problem is a paper on dynamic models of segregation by thomas schelling 197 1 although his socioeconomic analysis has revealed some of the dynamic properties of a racially mixed area with neighborhood externalities his model itself is quite unsatisfactory from the economic point of view since it lacks individual utility functions and thereby disregards the aspect of the individual choice of space and location within the city 2 as a result he failed to analyze the effect of spatial segregation within the city on the long run nature of the residential composition of the city in this paper i develop a long run dynamic model of an open city which accommodates two groups of households for example blacks and whites rich and poor young and old with their utility functions depending on a consumption good and residential space i also assume two kinds of neighborhood externalities the first is called negative intergroup externalities that is the utility level of a typical household in one group is adversely affected by an increase in the number of households in the other group living in the city the second is called positive intragroup externalities that is the utility level of a typical household in one group is positively affected by an increase in the size of its own group in in the city first i define a mixed city equilibrium as a long run equilibrium which allows the two groups to coexist in the city in the long run and then introduce a dynamic adjustment process of household movement into and out of the city it is proved that the mixed city equilibrium is always unstable in the presence of negative intergroup externalities and or positive intragroup externalities if residential land is perfectly homogeneous and there is no differential transport cost incurred within the city it turns out however that in the case of a monocentric city with positive transport cost the mixed city equilibrium may be stable or unstable depending on the degree of neighborhood externalities because of the stabilizing effect of spatial segregation between the two groups within the city

the demand for illicit drugs i introduction illicit drug use and alcohol abuse imposes significant costs on society and on the individual users these costs include increased crime health problems and employment problems because of these considerable costs government at all levels has made drug control and the control of alcohol abuse important priorities the federal government has undertaken an aggressive program of interdiction of drug shipments and eradication of drug crops in the field the federal government and the state governments have also increased their criminal justice efforts in analyzing the effect of government drug control programs economists have applied the conventional supply and demand model to illicit drug markets the model includes a demand function that is downward sloping with respect to price and a supply function that is upward sloping or horizontal with respect to price drug programs like interdiction and drug sanctions are assumed to reduce supply and raise equilibrium price other policy options such as some form of drug legalization could increase supply and reduce equilibrium price the effect of these policies on equilibrium quantity is dependent on the elasticity of demand and on whether demand shifts since not much is known about drug price elasticities the potential effects of various drug control policies remain a speculative exercise the purpose of this paper is to estimate the effects of alcohol and drug prices on alcohol use and drug participation both own price and cross price effects are estimated there are few prior empirical studies of the effect of drug prices because data have been difficult to acquire this paper makes use of newly available data on drug prices and is the first paper to link these data to a nationally representative drug use data set of 49 802 individuals estimates of drug price elasticities are important empirical evidence that drug sales can be characterized by market forces drug price elasticities are also important in estimating the likely impact of policies that affect drug prices and in estimating the effects of drug prohibition cross price elasticities are important to estimate since they suggest the likely effects of policies such as an increase in alcohol taxes on illicit drug participation and the effects of marijuana decriminalization on alcohol cocaine and heroin use ii prior studies while there are a number of prior studies of the effects of alcohol prices and policies there are few prior studies of drug prices and polices the reason for so few prior drug studies is the limited amount of data on drug prices and the limited options for linking these data to an individual record by residential area this study uses a new data set of cocaine and heroin prices from the drug enforcement agency that was linked to individual records by the office of applied studies at the substance abuse and mental health services administration leung and phelps 1993 provide a review of a number of recent alcohol demand studies the empirical literature provides considerable evidence that shows increasing the price of alcoholic beverages to decrease alcohol use alcohol demand studies generally estimate price elasticities for beer wine and spirits separately most studies employ aggregate data but a few use individual data studies using aggregate data find price elasticities for beer from about 2 to about 1 0 for wine from about 3 to about 1 8 and for spirits from about 3 to about 1 8 studies using individual data estimate price elasticities for beer from about 5 to about 3 0 for wine at about 5 and for spirits from about 5 to about 4 0 the few prior studies of the effect of decriminalization on marijuana use generally find that marijuana decriminalization has no effect on participation pacula 1994 thies and register 1993 dinardo and lemieux 1992 and johnston o malley and bachman 1981 all used samples of young people and found no effect of marijuana decriminalization

entrepreneurial police and drug enforcement policy the hypothesis that drug enforcement is relatively high in local jurisdictions where state laws dictate that police retain seized assets is tested in the context of a reduced form equation of the supply and demand for drug enforcement the results are robust across model specifications some of which directly control for the level of drug use legislation permitting police to keep seized assets raises drug arrests as a portion of total arrests by about 20 percent and drug arrest rates by about 18 percent police bureaucrats apparently desire discretionary budget increases and they have considerable discretion in determining resource allocation

the effects of excise taxes and regulations on cigarette smoking abstract we estimate a generalized linear model to examine adult and teenage cigarette demand our analysis focuses on the extent to which exice taxes and regulations restricting smoking in public places affect cigarette consumption the adult results indicate that the price elasticity of demand is unstable over time ranging from 0 06 in 1970 to 0 23 in 1985 these estimates are lower than most found in previous studies the teenage price elasticity does not differ statistically from the estimates for adults additionally regulations restricting smoking in public places have a significant effect on both adult and teenage cigarette demand

heroin consumption prices and addiction evidence from self reported panel data estimation models of drug demand should encompass the aspect of addiction here we consider two static panel data regression models and two cross section models with lags or leads in drug consumption as additional regressors heroin injectors attending a needle exchange service in oslo were interviewed twice with a one year interval despite our relatively small sample we obtain statistically significant price and income responses for nearly all of the models and specifications applied the sample is split by dealing status with dealers obtaining price elasticities in the range of 0 15 1 51 and non dealers 0 71 1 69 somewhat surprisingly the estimates of the variance of the latent individual specific variable are rather low in the panel data models although higher for non dealers than for dealers

a political economy theory of fiscal policy and unemployment this paper presents a political economy theory of fiscal policy and unemployment the underlying economic model is one in which unemployment can arise but can be mitigated by tax cuts and public spending increases such policies are fiscally costly but can be financed by issuing government debt policy decisions are made by a legislature consisting of representatives from different political districts the theory provides a positive account of the simultaneous determination of fiscal policy and unemployment the most important implication of the theory is that debt and unemployment levels should be positively correlated some evidence in support of this prediction is provided using data from a panel of developed countries

the future of social security we analyze the effect of the projected demographic transition on the political support for social security and equilibrium outcomes embedding a probabilistic voting setup of electoral competition in the standard olg model with capital accumulation we find that intergenerational transfers arise in the absence of altruism commitment or trigger strategies closed form solutions predict population ageing to lead to higher social security tax rates a rising share of pensions in gdp but eventually lower social security benefits per retiree the response of equilibrium tax rates to demographic shocks reduces old age consumption risk calibrated to match features of the u s economy the model suggests that in response to the projected demographic transition social security tax rates will gradually increase to 16 other policies that distort labor supply will become less important labor supply therefore will rise in contrast with frequently voiced fears

on proportional non representation this paper contends the main virtue conventionally attributed to proportional electoral rules i e effective representation of political views it discusses a number of shortcomings that lead too much proportionality to a self defeat it reduces vote mobility through the strong cultivation of voters loyalties it smooths out vote variations when transforming them into seat variations it reinforces intraparty ties to the detriment of vertical attention to constituents and it impinges on the working of checks and balances the paper does not aim at a systematic evaluation of the properties of various voting systems nor is it the proportional principle as such that is under attack however its combination with other institutional features can entrap voters in their own choices thus nurturing political collusion it is because of the ensuing lower influence of the voters on political decision making that too much proportionality can lead to poor representation

is property crime caused by drug use or by drug enforcement policy the relationships among drug offenses prorperty crime and the allocation of police resources are investigated in a structural model using data from florida countries law enforcement resources are scarce and as efforts to combat drug crime increase the amount of these resources allocated to property crime is reduced this reallocation of police resources results in reduced deterrence for property crime and as a result an increase in these crimes the evidence presented suggests that rising property crimes in florida are at least partially the result of drug enforcement policy

the effects of annuities bequests and aging in an overlapping generations model of endogenous growth we examine the effects of introducing actuarially fair annuity markets into an overlapping generations model of endogenous growth the complete annuitisation of agents wealth is not in general dynamically optimal the degree of annuitisation that is dynamically optimal depends nonmonotonically on the expected length of retirement and on the pay as you go social security tax rate the government has an incentive to restrict the availability of actuarially fair annuities contracts and can often move the economy from a pay as you go to a fully funded social security system via voluntary contributions to a government sponsored actuarially fair pension today accompanied by reductions in social security taxes tomorrow

on the political economy of deficit bias and immigration how much can governments shift the cost of their expenditure from today s voters to tomorrow s generations of immigrants without resorting to taxation that is explicitly discriminatory i demonstrate that if their societies are absorbing continuous flows of new immigrants we should expect governments that represent the interests of today s population to choose policies that shift some portion of the tax burden to the future even if that population is altruistically linked to future generations to measure the deficit bias i analyse the dynamic behaviour of an optimal growth model with overlapping dynasties and factor taxation calibrated for the us economy and consider the welfare implications for today s population and their descendants of intertemporal shifts in the tax rates on labour and asset income as well as transfer payments models with overlapping infinite lived dynasties allow for a very clear distinction between natural population growth an increase in the size of existing dynasties and immigration the addition of new dynasties they also provide an alternative to the strict dichotomy between models with overlapping generations where agents disregard the impact of their choices on future generations and the quasi ricardian world of infinite lived dynasties with representative agents that fully participate in both the economy and the political system in every period the trajectory of the debt burden predicted by the model is a good match for the rise in us federal government debt since the early 1980 s as well as the increases in debt projected by the congressional budget office over the next few decades

heterogeneous dynasties and the political economy of public debt we consider a small open overlapping generations economy with descending altruism heterogeneity is introduced by assuming that each parent procreates a fixed proportion of selfish children altruistic parents can recognize the type of each child there is no ricardian equivalence and an active public intergenerational transfer policy is attractive to altruistic dynasty members although there may be no unanimity among them we display reasonable conditions for indirect preferences to be single peaked and we apply the median voter theorem we then describe political equilibrium paths and discuss their compatibility with the steady path of an underlying closed economy with autonomous labor productivity growth

disentangling patterns of state debt financing we examine the determinants of change in state government indebtedness from 1961 through 1989 using a pooled time series cross sectional analysis the analysis reveals that debt is primarily a function of economic conditions reflecting both the need to borrow and the capacity of states to repay debt however political factors such as culture partisan competition and electoral cycles also affect state debt we also find very weak evidence that tax and expenditure limitations ironically may increase state indebtedness while constitutional debt limitations have no effect upon slowing the growth of state debt

the demand for cocaine by young adults a rational addiction approach abstract this paper applies the rational addiction model to the demand for cocaine by young adults in the monitoring the future panel the price of cocaine is added to this survey from the drug enforcement administration s system to retrieve information from drug evidence results suggest that annual participation and frequency of use given participation are negatively related to the price of cocaine in addition current participation frequency is positively related to past and future participation frequency the long run price elasticity of total consumption participation multiplied by frequency given participation of 1 35 is substantial

an intergenerational transfer model of state debt financing as federal budget deficits and the overall national debt have risen in recent years scholarly attention to the causes and consequences of federal indebtedness has also increased much of that research has focused upon the intergenerational distributive effects of relying upon debt as opposed to tax financing considerably less attention has been directed toward debt financing by the american states despite the fact that such borrowing has increased steadily over the last thirty years though not with the dramatic suddenness that characterizes increases in federal borrowing regens and lauth 1988 this paper examines debt financing at the state level as a policy choice with important intergenerational consequences the analysis assumes that debt financing is the result of political decisions based upon a calculation of the economic interests of different demographic groups within each state elected officials are believed to weigh those interests in the light of their states electoral and legal environments borrowing from an argument by alex cukierman and allan meltzer this paper examines the proposition that a state s long term debt financing is likely to be sizeable in absolute per capita terms and relative to tax revenues when two conditions are met 1 the state has a large elderly population and 2 recent economic growth trends indicate that future generations of state taxpayers may have an easier time paying off currently incurred debt than current taxpayers would have paying off government obligations on a pay as you go basis under these conditions a large portion of a state s electorate is likely to be bequest constrained meaning that they are not willing to donate an inheritance of fully financed government facilities and services to successive generations instead they are willing to borrow from their heirs by forcing future taxpayers to pay the costs of current consumption of governmental benefits

government debt in an overlapping generations model with bequests and gifts in 1974 robert barro argued that if individuals in successive generations were linked by bequests changes in the stock of government debt or in social security programs would have no effect on the steady state capital stock barro assumed that individuals held static expectations and that the size of the population was constant martin feldstein 1974 1977 had concluded that social security would reduce the capital labor ratio in models that did not admit a bequest motive and in his 1976 comment on barro argued that the introduction of government debt or social security into a perfect foresight dynamic growth model with bequests would still reduce the capital labor ratio barro replied that feldstein s criticisms were invalid if the steady state capital labor ratio were smaller than the golden rule level but would be correct if the opposite were true barro did suggest however that the latter possibility with overaccumulation of capital might be ruled out in his model as it was in miguel sidrauski 1967 but he was unable to demonstrate that the required behavior would be consistent with utility maximization by finite lived individuals 1976 p 345 although recent work by willem buiter 1979 jeffrey carmichael 1979 1982 truman bewley 1981 a b and others has helped to elucidate the nature of overlapping generations models with bequests and gifts and the issues in the barro feldstein debate they remain far from clear the purpose of this paper is to shed a little more light on the subject in what follows i contend that some of the authors cited above either have specified the individual s optimization problem in an asymmetric way or have failed to impose necessary conditions for a sensible optimization problem or both there is a natural specification of the barro model 1 that emphasizes the similarity between this model and optimal growth models see for example david cass 1965 peter diamond 1973 here in steady state equilibrium the aftertax interest rate r must equal the rate at which individuals discount the utility of their heirs p r p has become known as the modified golden rule and a meaningful individual optimization problem requires that p exceed n the natural growth rate of the economy my results confirm barro s hunch about his model in a barro model r must exceed n much of the barro feldstein 1976 interchange which assumed that r could have any relation to n is wrong headed barro and feldstein reach different conclusions about the effects of government debt and social security because they assume different individual utility functions also my results contrast sharply with those of buiter and carmichael for example carmichael concluded that with intergenerational transfers from parents to children bequests r must exceed n but with transfers in the opposite direction n must exceed r 1982 pp 205 06 indeed i believe that the buiter carmichael representation of the barro model is logically faulty see section ii in section i i outline an overlapping generations model with gifts and bequests and derive its steady state properties in the next section i discuss the shortand long run effects of introducing government debt into the model and contrast my results with those

the price elasticity of hard drugs the case of opium in the dutch east indies 1923 1938 at the beginning of this century the dutch government controlled the opium market in the dutch east indies nowadays indonesia for several decades this state monopoly was called the opiumregie using information gathered during the opiumregie this paper estimates price elasticities of opium consumption it appears that short term price elasticities of opium use are about 0 7 long term price elasticities are about 1 0

a comparison of alternative models for the demand for medical care we have tested alternative models of the demand for medical care using experimental data the estimated response of demand to insurance plan is sensitive to the model used we therefore use a split sample analysis and find that a model that more closely approximates distributional assumptions and uses a nonparametric retransformation factor performs better in terms of mean squared forecast error simpler models are inferior either because they are not robust to outliers e g anova anocova or because they are inconsistent when strong distributional assumptions are violated e g a two parameter box cox transformation

a positive theory of social security in many countries social security accounts for a large fraction of the government budget why is this so given that at any point in time the number of recipients of social security benefits is smaller than the number of contributors in the overlapping generations model studied in this paper all individuals currently alive vote on social security in every period in equilibrium the size of social security is larger the greater is the proportion of elderly people in the population and the greater is the inequality of pre tax income within each generation both predictions of the theory are supported by the empirical evidence in cross country data

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

the effect of cocaine prices on crime the relationship between cocaine prices and crime has critical implications for u s drug policy but is theoretically indeterminate because cocaine price changes affect crime through changes in both cocaine consumption and expenditures this paper investigates this relationship in annual data from 1981 95 on 29 large u s cities accounting for simultaneity by using two stage least squares with measures of wholesale supply factors and retail enforcement intensity as instruments for cocaine prices controlling for prices of other drugs deterrence socioeconomic factors and city and year specific effects a strong negative relationship exists between cocaine prices and six of seven fbi index crimes

altruism deficit policies and the wealth of future generations i introduction there is now a substantial body of evidence suggesting that altruistic financial bequests are zero for the vast majority of households 1 other studies seem to indicate that the financial bequests which are made are not likely to be altruistically motivated 2 while this evidence against the importance of altruistic financial bequests seems reasonably convincing it is by no means clear that the importance of altruism per se has been dismissed 3 for example the results reported in altonji hayashi and kotlikoff 1992 tables 14 17 indicate that extended family resources while not perfectly linked to own resources are important for explaining own consumption the authors do not reject the notion that substantial altruistically motivated transfers occur in the u s rather they suggest the altruistically motivated transfers which are made take the form of less than fully efficient human capital transfers to children if most altruistic transfers do take place via educational expenditures how does this affect the ricardian equivalence theorem robert barro 1974 1989 argues the presence of any altruistic transfer is sufficient to guarantee that intergenerational transfers caused by government policy are neutral other forms of intergenerational transfers such as inter vivos gifts to children support of children s education and so on can work in a similar manner therefore the ricardian results will hold even if many persons leave little in the way of formal bequests 1989 41 4 an alternative view however is expressed by allan drazen 1978 he argues if parents possess an insufficient mix of wealth and altruism intergenerational transfers could be exhausted before the efficient level of human capital investment is achieved if explicit or implicit loans between parents and children are not possible then the government may be able to improve welfare by generating intergenerational transfers from children to parents 5 a cut in the parents tax burden and an equal present value increase in the tax on the next generation is equivalent to a government enforced loan at the going market interest rate since educational expenditures are inefficiently low the return on human capital investment exceeds the loan rate therefore parents could put an amount less than the tax cut into their children s education and still leave the children with enough additional income to pay for the future tax increase thus a deficit policy serves to expand the consumption possibility set of the family viewed in this way drazen 1978 514 footnote 7 imagines an argument for a pareto optimal level of public debt issue 6 a third possibility was identified by nerlove razin and sadka 1988 who conduct the most explicit analysis of government transfers in an economy with altruistic but financial bequest constrained households they also find a transfer or implicit loan to parents from their children will make the parents unambiguously better off however they were the first to point out that a deficit policy may lower the welfare of the children although they fail to explain why thus even in the presence of altruistic transfers from parents to children the effect of deficits on the consumption of future generations is far from clear in this paper we wish to clarify the effect of intergenerational transfers on bequest constrained families the next section intuitively explains why a government loan or deficit policy generates an ambiguous effect on the children s consumption even though altruistic parents are fully capable of making both generations better off after the loan we also identify the key structural determinants of the change in the children s wealth due to the loan in section iii we extend the simple model of section ii to a more quantitatively realistic multi period life cycle simulation model of a bequest constrained household the simulation model is then used in section iv to examine how a government intergenerational transfer affects the consumption of each generation under various settings of the key structural determinants identified in section ii

patinkin on keynes and meltzer abstract don patinkin s discussion of alternative interpretations of keyne s general theory gave considerable weight to an author s motivation particularly mine patinkin also restates his view that the general theory offers a short run disequilibrium approach i suggest that textual interpretation in economics should not consider motives because better methods are available and are now used i propose three standards applying these standards i find little support for patinkin s interpretation of the general theory although my interpretation better meets the three standards i conclude that the general theory does not have a single correct interpretation

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
