international bargaining in the presence of global environmental change this model deals with the greenhouse effect that is to say with a problem of international pollution through a description of the bargaining process it aims to determine the different forms that may be taken by cooperation agreements between the countries involved we demonstrate in particular that under some conditions it is always possible for the countries to reach an agreement such agreements are the work of a group of so called leader countries characterized by their commitment in favour of cooperation these leader countries use transfers to induce other countries to join them but they can be insufficiently attractive to convince all the countries to cooperate so as we show in the discussion the cooperation is not necessarily total therefore the key of a common problem can be a partial cooperation and not necessarily a common cooperation

climate coalitions and international trade assessment of cooperation incentives by issue linkage this paper investigates climate control coalition games it studies whether incentives exist for non cooperating nations like the usa to join a coalition based upon issue linkage issue linkage is considered through increased r d expenditures triggering improved technological innovations that advance energy efficiencies model calculations demonstrate that incentives exist for non cooperating countries like the usa to join a climate control coalition if nations cooperate on technological innovations restrictions on trade such as sanction mechanisms against non cooperating countries are not necessarily an incentive to join a coalition technological spillover effects lead to improved economic situations and increased energy efficiencies in non cooperating countries

the effects of taxation price control and government contracts in oligopoly and monopolistic competition abstract many government contracts with or policies towards oligopolistic sectors essentially involve private firms selling a given proportion or quantity of output to the government at a fixed price p r with the remainder being sold on the open market often this is combined with consumer rationing examples include cement and sugar in india and health housing and defence in many countries the paper investigates the effects of these schemes including sales and excise taxation on prices output and household welfare under oligopoly and monopolistic competition less government control reduced may raise prices and tax shifting can be above or below 100 percent

corruption trade and resource conversion abstract recent evidence suggests that special interest groups significantly affect tropical deforestation through lobbying we develop an open economy model in which resource conversion is determined by a self interested government that is susceptible to the influences of the political contributions it receives from the profit maximizing economic agent responsible for land conversion we investigate the effects of lobbying on the cumulative level of resource conversion and examine how trade policy influences the distortions created by political corruption we derive testable predictions that are analyzed through a panel analysis of cumulative agricultural land expansion over 1960 99 for low and middle income tropical countries our findings suggest that increased corruption and resource dependency directly promote land conversion whereas rising terms of trade reduce conversion

co operation and unilateral commitment in the presence of global environmental problems this paper focuses on the link between group co operation and unilateral commitment of some countries in the presence of global environmental problems we show that in case of a failure of negotiation some countries can decide to commit unilaterally and reduce their emissions we call this behaviour precautionary commitment absence of international agreement does not mean global defection from the environmental issue we also show that the emergence of a non co ordinated global co operation can result from a strategic action from the members of the coalition the insiders of the coalition create an incentive for the non members to reduce without co ordinating their emissions

global trading versus linking architectures for international emissions trading abstract international emissions trading is widely seen as an indispensable policy pillar of climate change mitigation stern n 2007 the economics of climate change the stern review cambridge university press new york this article analyzes five different types of trading architectures classified into two top down unfccc driven and three bottom up driven by individual countries or regions approaches the two types of approaches are characterized by a trade off between environmental effectiveness and political feasibility respectively whereas their relative cost effectiveness depends on implementation details bottom up architectures constitute imperfect substitutes for top down architectures in terms of environmental effectiveness and thus remain mere fallback options however especially the formal linking architecture can act as complement in terms of cost effectiveness

harmonization of carbon taxes in international climate agreements the use of some kind of carbon tax is often proposed as part of an international climate policy one possibility could be an international climate agreement requiring a harmonization of domestic carbon taxes it is shown that there are several practical difficulties with such an agreement and that it therefore is unlikely that co2 emissions will be allocated efficiently between countries with this type of agreement alternative types of agreements include an international carbon tax in which the governments of the participating countries pay a tax in proportion to their co2 emissions to an international agency a very similar arrangement would be to introduce a system of emission permits which are internationally tradeable between governments under quite general conditions agreements of these two types can be designed so that they are both efficient and satisfy whatever distributional objectives one might have under both of these systems the choice of domestic policies could be left to the individual countries a domestic carbon tax is an obvious policy response from a country participating in an agreement of this type

games of climate change with international trade we analyse games of greenhouse gas emission reduction in which the emissions and the emission reduction costs of one country depend on other countries emission abatement in an analytically tractable model we show that international trade effects on costs and emissions can either increase or decrease incentives to reduce emissions and to cooperate on emission abatement in some specifications optimal emission reduction is unaffected by trade we therefore specify the model further calibrating it to larger models that estimate the costs of emission reduction trade effects and impacts of climate change if trade effects are driven by total emission reduction costs of other countries cooperation is slightly more difficult than in the case without trade effects if trade effects are determined by relative emission reduction efforts in other countries cooperation becomes easier carbon leakage does not affect our qualitative insights although it does change the numbers

international trade and environmental quality a survey abstract international trade has been incorporating various aspects of environmental issues since 1970 the extent to which environmental problems might affect many facets of trade or vice versa has been the subject of considerable debate over these years in this article we have attempted to establish some of the links between international trade and environmental quality by performing a comprehensive literature review we discuss issues such as establishing direct and indirect effects of international trade on environmental quality effects of trade on economic development environmental quality and energy and their relation with each other and finally the role of governments and international organizations in this context studies have so far revealed some linkages between trade and environment through conventional trade theory however interactions between international trade and types of pollution their sink and assimilative capacity need to be analyzed using a general equilibrium approach currently very little knowledge and agreement on the nature of interactions between trade theories development process and environmental quality exist existing studies have shown that the structure of environmental regulations should be modified to reflect the existence of trade under imperfect competition therefore further research on the interaction between new trade theory and environmental regulation is needed also theoretical and quantitative analysis regarding the effects of environmental regulations on competitiveness and location decision is needed the intensity and type of environmental measures vary across issues and countries therefore harmonizing environmental measures creates an inefficient atmosphere and to assume that trade restrictions will either improve or reverse the environmental damages is a serious mistake given the dynamic and intricate nature of the problem trade and environment debate continues despite vast research and poses a challenge for researchers and policy makers in the foreseeable future

the changing climate of climate change economics climate change economics is now four decades old much of what it has achieved as a field of academic enquiry can be linked back to issues of integrated assessment modelling this paper shows that the standard approach is going through a major change in scope as of the last five years the conventional focus on determining optimal mitigation paths based on modelling the social cost of carbon is being enlarged to embrace promising new waves of research these are 1 the economics of insurance against catastrophic risks 2 the economics of trade and climate and 3 the economics of climate change adaptation the paper helps to bridge the gap between economics and climate policy by showing that the analytical toolkit of climate change economics has shifted towards more realistic representations of climatic policy

political internalization of economic externalities and environmental policy abstract this paper derives the characteristics of endogenous environmental policy in a common agency model of politics and proceeds to show that competition between lobby groups is an important source of internalization of economic externalities our analysis generalizes bhagwati s principle of targeting to the case of distorted political markets moreover we show that the politically optimal structure of environmental taxes incorporates a pigouvian adjustment however since lobby groups care about the distribution of income as well as about efficiency the equilibrium structure of taxes differs considerably from the pigouvian rule

management of transnational commons coordination publicness and treaty formation this paper focuses on the formation of treaties to manage transnational commons when efforts must be coordinated among a minimal sized group so as to make cooperation worthwhile by focusing on mixed strategy equilibria we are con cerned with instances where the intentions of others are uncertain the number of required participants the pattern of payoffs transaction costs and the underlying technology of public supply aggregation are key factors behind the achievement of coordina tion we apply our analysis to explain the outcome of negotiations on stratospheric ozone depletion global warming acid rain and tropical deforesta tion jel q20 d70

environmental consciousness and moral hazard in international agreements to protect the environment abstract a group of countries that can potentially commit to cooperation to protect the environment are identified as environmentally conscious countries conditions are examined under which they can provide self financing side payments too a second group of less environmentally conscious countries so that the two groups form a global or partial stable coalition that agrees to reduce emissions a mechanism that detects cheating is also developed in order to induce the desired emissions even when the emissions level of an individual country cannot be observed by the rest of the participating countries

the abatement market a proposal for environmental cooperation among asymmetric countries we present a model of interaction among technologically asymmetriccountries whose use of an open access environmental resource generatesmutual externalities we show that countries can improve bothenvironmental quality and their individual welfare levels by buying sellingpollution abatement this market mechanism which reduces incentive forfree riding is more effective the larger the technological gap betweencountries

endogenous minimum participation in international environmental agreements an experimental analysis almost all international environmental treaties require a minimum number of countries to ratify the treaty before it enters into force despite the wide spread use of this mechanism little is known about its effectiveness at facilitating cooperation we analyze an agreement formation game that includes an endogenously determined minimum participation constraint and then test the predictions using economic experiments we demonstrate theoretically that players will vote to implement an efficient coalition size as the membership requirement and this coalition will form experimental tests of the theory demonstrate that the minimum participation mechanism is highly effective at facilitating cooperation when efficiency requires the participation of all players however when efficiency requires only a subset of players to participate profitable coalitions are often deliberately blocked in light of our results it is possible that equity concerns can impede the formation of international agreements when membership requirements allow free riders

the problem of global environmental protection what distinguishes global common property problems and global unidirectional externalities from the ones that arise under a single jurisdiction is that there is no global authority empowered to intervene and regulate use of global environmental resources cooperation is needed the paper discusses when cooperation is most needed and how it might be obtained cooperation might emerge from a noncooperative setting if supergames are played if the actions of any one country are explicitly contingent on the actions undertaken by other countries or if moral concerns lead countries to consider the consequences of their actions for others cooperation emerges in an explicit though limited form when countries commit to regulate themselves in signing international agreements in these cases the signatories cooperate but the agreements are self enforcing an attempt is made to relate these theoretical concepts to the practice of global environmental protection copyright 1990 by oxford university press

strategic transfers and private provision of public goods abstract this paper considers strategic monetary transfers between two agents when these contribute to a mutual public good if the agents differ in their contribution productivity then the less productive agent has an incentive to make large unconditional transfers to the more productive agent although agents move simultaneously in each stage of the game the less productive agent becomes a stackelberg leader furthermore the generic subgame perfect equilibrium is characterized by full specialization

understanding heterogeneity in price changes and firm responses to a national unhealthy food tax in mexico to address the high prevalence of overweight and obesity in mexico an eight percent ad valorem excise tax on non essential energy dense foods came into effect on 1 january 2014 this paper estimates price changes after the tax implementation among the top four food categories and by leading vs non leading firms using purchase information from over 6000 urban households in the 2012 2015 nielsen mexico consumer panel we create product city month specific prices that correct for potential biases associated with household and retailer characteristics using these corrected prices we conduct before and after quasi experimental analyses and find that price increases were larger than eight percent for cookies but were less than eight percent for ready to eat cereals salty snacks and pre packaged sweet bread for the latter food group event study analyses on the gradual price change over time suggest that price changes might be the result of an increasing price trend rather than the tax implementation firm level analyses mostly show that price increases by the leading firms were larger than the overall increase at the food market level helping explain variability in post tax declines in food purchases as reported in other research we also find that price changes are generally underestimated when we do not correct prices for biases associated with households and retailers these results improve our understanding of the mechanisms behind heterogeneous changes in purchases after the tax implementation additionally these results can assist policymakers when designing or improving taxes on non essential energy dense foods at a time when these policy options are high on the agenda in many places

how auctions work for wine and art interview auctioneers and even to buy a little wine in the meantime i have also had the opportunity with john abowd 1988 to observe and collect data on the auction sale of impressionist and contemporary paintings this paper reports on some of the empirical regularities that i and others have observed in the actual operation of the auction markets for these items in view of the rich and diverse array of theoretical literature on auctions it seems high time economists began to spell out precisely what facts it is meant to explain 2

a survey of recent empirical work concerning auctions in this paper the authors survey some recent empirical work concerning auctions first outlining two complementary approaches to the empirical analysis of auctions and then discussing several recent developments in the econometric analysis of field data concerning auctions

the comparison between ad valorem and specific taxation under imperfect competition abstract this paper compares ad valorem and specific taxation in two models of oligopoly with and without free entry predominantly ad valorem taxation implies a relatively low consumer price high tax revenue and when entry is precluded low profits ad valorem taxation dominates specific taxation from the welfare perspective the set of circumstances under which with free entry specific taxation raises welfare is a strict subset of that in which ad valorem taxation is welfare improving and in both models the maximisation of consumer welfare subject to a binding revenue constraint requires maximum reliance on ad valorem taxation

commercial culture political culture and economic policy polarization the case of japan abstract in this paper we present a model of endogenous policy formation that captures crucial aspects of the japanese commercial and political culture we analyze the influence of certain cultural traits and show that cultural idiosyncrasies are important determinants of policy formation especially the complex interaction of the two types of cultures is shown to have significant consequences for the polarization of policy stances contrasting our model s behavior with the stylized facts of japanese politics we arrive at the conclusion that the model s behavior is compatible with the observed policy positions held by japanese politicians over the last 50 years

heterogeneity in the tax pass through to spirit retail prices evidence from belgium abstract on 1st november 2015 the belgian government increased the excise tax on alcoholic beverages for spirits with 40 of alcohol and bottle size of 70 cl this tax change is equivalent to an amount of 2 43 per bottle of spirits this paper studies the impact of this tax reform at the store level on the posted retail price of six major brands of spirits using a difference in differences method the estimation is based on a balanced panel of scanner data from a major supermarket chain with a 33 market share and uses the retail prices of the same brands sold in france by the same supermarket chain as a control group having information on each store location we show spatial variations in the tax pass through for homogeneous products we find that these variations are strongly related to the intensity of local competition and to a lesser extent to the proximity to the borders mainly with luxembourg which is the low price country we find that the tax was quickly passed through during the first month of tax implementation and that it was mostly over shifted however we also find that both the border and the competition effects are not instantaneous but arise several months after the tax reform these findings have important implications for alcohol control policies as they highlight that the incidence of alcohol taxation can vary greatly across space and affect differently households depending on where they live

the role of dutch auctions and lotteries in shaping the art market s of 17th century holland abstract this article examines institution formation in the nascent art markets of 17th century amsterdam and haarlem in response to external and internal pressures on artists guilds in amsterdam poor quality imports often copies were touted as originals and sold in clandestine dutch auctions the deliberate confusion about quality imparted to the market features similar to those of akerlof s lemons model and a need for quality guarantees gave occasion to dealers in haarlem and other towns demand was viewed as fixed and guilds toughened restrictions on the supply side dissenters successfully used lotteries to show that demand can be engendered promotion was to become a key feature of later art markets

2 00 gas studying the effects of a gas tax moratorium there are surprisingly few estimates of the effects of sales taxes on retail prices especially at the firm level we consider the temporary suspension and subsequent reinstatement of the gasoline sales tax in illinois and indiana following a price spike in 2000 earlier laws set the timing of the reinstatements providing plausibly exogenous changes in the tax rates using a unique dataset of daily prices at the gas station level 70 of the tax suspension is passed on to consumers in the form of lower prices while 80 100 of the tax reinstatements are passed on to consumers some evidence suggests that these short run pass through estimates are smaller near the state borders with the tax reinstatements associated with relatively higher prices up to an hour s drive into neighboring states

international coordination on climate policies given the current trend in global emissions the latest round of climate change negotiations at the durban meeting of december 2011 for the adoption of a comprehensive global treaty on climate change mitigation as soon as possible and no later than 2015 and to come into force in 2020 has hardly shown the results one would have hoped for even for the most optimistic it remains unclear whether one can expect a successful negotiating outcome by 2015 there are inherent difficulties associated with climate change negotiations ranging from which countries should bear most responsibility for a given emission reduction target to the assessment of a globally efficient time path for pricing harmful greenhouse gas emissions ghgs these difficulties become even more complex and challenging under the pervasive uncertainty of climate science and the uncertainty about the feedback loop between climate change damages and economic growth during the past decades the environmental economics literature has provided important insights regarding the design of environmental fiscal policies and treaties but there is a host of issues that remain relatively unexplored for instance we know little about the cooperative solution for carbon and trade policies when climate change affects the productive possibilities of countries in this context it is also not obvious whether observed policies could be improved upon in such a way that all countries gain in welfare it remains also unclear what the carbon extraction path should be in the absence of a comprehensive treaty such as for example if environmental policy is unilaterally chosen subject to an agreed ceiling in global temperature though carbon pricing instruments like carbon taxes cap and trade and hybrids have been well studied not much is known about their properties in the presence of offset schemes such as the clean development mechanism more work is also required to understand the strategic implications of the uncertainty surrounding climate change and how this affects for example the choice of climate change strategy precautionary or wait and see how uncertainty impacts the propensity of countries to sign a climate treaty and the extent to which the possibility of a climate catastrophe fosters or hinders cooperation understanding political economy issues is also vital in tackling climate change because efficient climate policies stand little chance of being successfully negotiated and implemented if they do not receive the support of the electorate the papers in the special issue of the journal of environmental economics and management are precisely devoted to this broad research agenda

regional versus global cooperation for climate control abstract this paper considers whether international environmental public goods provision such as mitigation of climate change is better dealt with through regional cooperation than through a global treaty previous research suggests that at best a global environmental treaty will achieve very little at worst it will fail to enter into force using a simple dynamic game theoretic model with weakly renegotiation proof equilibrium as solution concept we demonstrate that two agreements can sustain a larger number of cooperating parties than a single global treaty the model provides upper and lower bounds on the number of parties under each type of regime it is shown that a regime with two agreements can pareto dominate a regime based on a single global treaty we conclude that regional cooperation might be a good alternative or supplement to global environmental agreements

are alcohol tax hikes fully passed through to prices evidence from alaska on 1 october 2002 the state of alaska increased taxes on malt beverages from 0 35 per gallon to 1 07 per gallon increased taxes on wine from 0 85 per gallon to 2 50 per gallon and increased taxes on distilled spirits from 5 60 per gallon to 12 80 per gallon the net effect is that the tax on a standard serving rose from about 3 cents for beer 2 cents for wine and 4 cents for spirits to a uniform tax of 10 cents per standard serving of each type of alcohol beverage this paper uses primary data on alcoholic beverage prices in alaska to study a very basic question what was the impact of the tax hikes on prices an alcohol tax hike is often viewed as a public health policy tool to discourage excessive alcohol consumption and alcohol related problems such as drunk driving the impact of a tax hike on alcoholic beverage prices is a key link in the chain of the causality from the tax to public health economic theory and previous empirical studies mainly of taxes on goods other than alcoholic beverages do not provide very much guidance on what to expect following a tax hike it is an empirical question to answer the question i conducted telephone surveys just before and a year after the tax hike of on premise and off premise alcohol retail establishments across alaska

coalition formation in international environmental agreements and the role of institutions abstract the aim of this paper is to discuss the role played by international institutions in achieving effective international environmental agreements we emphasise the strategic nature of environmental negotiations and use a game theoretic model of coalitional bargaining to illustrate the main issues we argue that international institutions can intervene in the framing of the strategic interactions between countries i e setting the rules of the negotiation game and can influence the actual agreement reached when different outcomes of the negotiation game can be equilibria

altruism and global environmental taxes a global externality like the ghg emissions leading to climate change are both due to free riding at the individual level as well as the government level a government aiming to maximise domestic social welfare may make individuals internalise the damage within their country but will free ride on the damage caused to other countries only a global cooperative solution could internalise global damage entirely if individuals have altruistic concern for others but continue to believe that their consumption is negligible relative to the total they will not change their behaviour however this paper shows that in a multi country setting the global equilibrium levels of consumption for both the non cooperative and cooperative solutions are affected by altruism the key results are a that non cooperative governments maximising domestic welfare will internalise some of the damage inflicted on other countries depending on the level of altruistic concern individuals have and b the cooperative global optimum also changes as altruism leads individuals to effectively experience damage in other countries as well as the direct damage to them since altruistic concern for others may vary across countries global welfare then becomes a function of the relative levels of altruistic concern between countries

the impact of a soda tax on prices evidence from french micro data abstractbased on an original data set of more than 500 000 non alcoholic beverage price records we evaluate the impact on consumer prices of the soda tax an excise on drinks with added sugar or sweetener introduced in france in january 2012 we adopt a difference in differences approach and find that the tax was gradually passed through to the prices of the taxed beverages after 6 months of its introduction it was fully shifted to soda prices and almost fully shifted to the prices of fruit drinks while the pass through for flavoured waters was incomplete we also find that the pass through was heterogeneous across brands and retail groups

exploring the role of economic incentives and spillover effects in biodiversity conservation policies in sub saharan africa abstract a vast array of empirical work investigates the issue of biodiversity conservation but the focus is often limited on the search for possible causes of biodiversity erosion biodiversity conservation policymaking is still understudied in this study this gap is empirically addressed on a sample of 48 sub saharan countries over the 1990 2009 period taking the ecoregion protection score provided by the center for international earth science information network ciesin as a measure of biodiversity conservation policies it is sought whether economic incentives such as biodiversity targeted international transfers as well as tourism revenues have an impact on biodiversity conservation policies moreover spillover effects are also hypothesized owing to the public good character of biodiversity conservation policies international financial assistance as well as tourism are found to have an effect on biodiversity conservation policymaking our results also evidence complementary spatial spillover effects between biodiversity conservation policies

interior matching equilibria in a public good economy an aggregative game approach abstract if the equilibrium generated by a matching mechanism is to be the desired pareto optimal outcome it is necessary for every player to be at an interior solution at that equilibrium using the aggregative game approach developed by cornes and hartley 2003 2007 this paper analyzes the conditions under which matching mechanisms in a public good economy lead to interior matching equilibria at which all agents make strictly positive flat contributions to the public good in particular we show that the distribution of income among the agents is crucial for both the existence of interior matching equilibria and warr neutrality in the case of matching

price expectations and international quota trading an experimental evaluation this paper reports a preliminary experimental test of international quota trading on a market characterized by several dominant traders uncertain quota demand and supply imply true market clearing prices that in general differ from an expected competitive quota price however in the experiment the expected price level emerges as a focal point on which the bulk of quota trade contracts are keyed thus incomplete price discovery occurs

adverse selection in the market for slaves new orleans 1830 1860 this paper seeks to cast some light on the importance of adverse selection in competitive markets by examining the market for the sale of slaves in pre civil war new orleans estimates of the degree of adverse selection in the new orleans market are obtained by examining the relative prices of slaves from different regions of origin these estimates indicate that slaves brought to market may on average have been of 20 percent to 40 percent lower quality than the slave population in general and that good slaves were perhaps three times less likely to be sold than low quality ones

viewpoint soda taxes four questions economists need to address abstract the popularity of soda taxes as a public health policy has grown rapidly in the last few years while the evidence that the tax works in reducing the purchases of soda is emerging there are a number of questions that are yet to be answered before the broader effectiveness of this measure can be determined beyond health effects there is more specifically a need to better understand the economic mechanisms of change redistributive effects as well as causal and spillover effects in food systems and economy more broadly

environmental regulations transfers and trade theory and evidence abstract this paper develops a theory of compensation of producers for the costs associated with environmental regulations we show that the existence of transfers can give counter intuitive effects of environmental policy on both output and trade flows in particular the compensation obtained by producers neutralizes the effect of environmental policy on output and consequently on trade flows this may help explain why previous empirical research has found weak evidence that environmental regulations affect trade patterns the theory is tested using agricultural sector data the evidence supports the hypothesis that environmental regulations and transfers are positively correlated

bilateral or multilateral bargaining in the face of global environmental change this model deals with the problem of the greenhouse effect a problem of transfrontier pollution it consists of determining through the description of a bargaining process the conditions under which it is preferable for the developing countries to speak with a united voice and those conditions under which it is preferable for them to negotiate separately one from the other in particular it is shown that the agreements arising from the bargaining cannot be equitable and for that reason they include only a limited number of countries

auctions and bidding a primer maybe the contractor was right to think bid jobs are different but it is more likely that he suffered from too simple a view of what is involved in preparing a competitive bid our analysis will show that even an experienced estimator working in familiar terrain can lose money if he doesn t understand the subtleties of competitive bidding the phenomenon experienced by the painting contractor known as the winner s curse is just one of the surprising and puzzling conclusions that have been turned up by modern research into auctions another is the theoretical proposition supported also by some experimental evidence that for example a sealed bid treasury bill auction in which each buyer pays a price equal to the highest rejected bid would yield more revenue to the treasury than the current procedure in which the winning bidder pays the seemingly higher amount equal to his own bid there are also subtle results that demonstrate the equivalence of such apparently different institutions as the standard sealed bid auction in which the auctioneer seller sells the goods to the highest bidder for a price equal to his bid and the dutch auction in which the auctioneer seller begins by asking a high price and gradually lowers the price until

who pays cigarette taxes the impact of consumer price search abstract we conduct an empirical study of the impact of consumer price search on the shifting of cigarette excise taxes to consumer prices we use novel data on the prices that smokers report paying and document substantial price dispersion we find that cigarette taxes are shifted at lower rates to carton buyers and especially smokers who buy cartons of cigarettes in a state other than their state of residence we also find evidence that taxes are shifted at somewhat lower rates to the prices paid by heavier smokers and at somewhat higher rates to the prices paid by smokers of light cigarettes

reference prices costs and nominal rigidities we assess the importance of nominal rigidities using a new weekly scanner dataset we find that nominal rigidities take the form of inertia in reference prices and costst defined as the most common prices and costs within a given quarter reference prices are particularly inertial and have an average duration of roughly one year even though weekly prices change roughly once every two weeks we document the relation between prices and costs and find sharp evidence of state dependence in prices we use a simple model to argue that reference prices and costs are useful statistics for macroeconomic

implications of a sugar sweetened beverage ssb tax when substitutions to non beverage items are considered abstract using the 2006 homescan panel we estimate the changes in energy fat and sodium purchases resulting from a tax that increases the price of sugar sweetened beverages ssbs by 20 and the effect of such a tax on body weight in addition to substitutions that may arise with other beverages we account for substitutions between ssbs and 12 major food categories our main findings are that the tax would result in a decrease in store bought energy of 24 3 kcal per day per person which would translate into an average weight loss of 1 6 pounds during the first year and a cumulated weight loss of 2 9 pounds in the long run we do not find evidence of substitution to sugary foods and show that complementary foods could contribute to decreasing energy purchases despite their significantly lower price elasticity the tax has a similar effect on calories for the largest purchasers of ssbs

bretton woods blueprint for a greenhouse gas agreement abstract this paper describes the remarkable parallels between the problems faced in the drafting of the 1944 bretton woods agreement which established the rules and institutions governing the international financial system and the problems faced in drafting a greenhouse gas agreement the parallels include the need to induce countries to sacrifice economic sovereignty in order to provide a public good the need to facilitate capital investment and provide adjustment loans to be fair to developing versus developed nations to offer technical assistance monitor behavior punish offenders and promote a globally efficient allocation of resources it is claimed that between them the organizations which emerged from the bretton woods agreement namely the imf gatt and world bank have the necessary attributes of the needed global atmospheric control agency furthermore it is argued that there are striking parallels between the reserve accounts at the imf and the crediting and debiting of greenhouse gas emissions and absorptions between special drawing rights sdrs and rights for greenhouse gas emissions as well as in numerous other characteristics the paper concludes by noting that the almost half century of influence of the bretton woods institutions suggests we might borrow from their charters organizational designs membership incentives and procedures for adaptation and change

fuel tax incidence and supply conditions abstract the incidence of taxes on consumers and producers plays a central role in evaluating energy tax policy yet the literature testing the main predictions of the tax incidence model is sparse in this paper we examine the pass through rate of state gasoline and diesel taxes to retail prices and importantly we estimate the dependence of pass through on factors constraining the gasoline and diesel supply chains we consider several factors that alter the elasticity of supply including within state heterogeneity in gasoline content requirements refinery capacity utilization inventory constraints and variation in the demand for untaxed uses of diesel in general we find that in periods of time when the supply chain is constrained and the constraint is plausibly unrelated to shifts in demand the pass through rate of fuel taxes declines we describe several potential implications for tax policy including tax breaks during peak driving season and during times of supply disruptions such as after major hurricanes

the co2 abatement game costs incentives and the enforceability of a sub global coalition abstract this paper studies the economic incentives and the institutional issues governing the outcomes of a short term climate change policy package guided by the united nations framework convention on climate change and the berlin mandate initiatives game theoretic tools and the global trade environment interface are explored within a 26 region 13 commodity computable general equilibrium framework to characterize the incentives of oecd regions to comply with a non binding agreement in a carbon abatement coalition the results showed that in the absence of side payments the achievement of such a coalition might require the design of suitable trade instruments

targets for global climate policy an overview a survey of the economic impact of climate change and the marginal damage costs shows that carbon dioxide emissions are a negative externality the estimated pigou tax and its growth rate are too low to justify the climate policy targets set by political leaders a lower discount rate or greater concern for the global distribution of income would justify more stringent climate policy but would imply an overhaul of other public policies catastrophic risk justifies more stringent climate policy but only to a limited extent

environmental regulation in an open economy abstract environmental regulation by a large trading country affects the world price of traded commodities a series of second best environmental taxes are derived which explicitly incorporate trade effects for cases which depend on the type of externality the regulating country s commodity trade balance and the presence or absence of trade taxes in the regulated market a coordinated policy solution using both tax and tariff instruments also is derived the practical implications for domestic environmental policy making which emerge from the theoretical results are evaluated

trade policy reform endogenous lobby group formation and environmental policy abstract this paper explores the effects of trade liberalization on environmental policy outcomes when collective action is endogenous the polluting industry s ability to undertake lobbying is shown to depend on the degree of competition in the product market establishing a new link between trade and environmental policies if trade liberalization causes industry collective action to become harder to sustain the stringency of the environmental policy is likely to rise these results highlight the role of trade liberalization on product market competition and its consequent impact on the incentive to lobby for less stringent environmental policies

environmental policy reconsidered the role of technological innovation abstract this paper discusses recent environmental policy wisdom in the light of technological and organizational innovation starting from empirical evidence it argues that the main econometric models which are used in environmental policy analysis do not consider properly the determinants and effects of innovation and offer unreliable estimates of policy effects some solutions to the latter problem show that the integration between environmental policy and industrial policy can be more efficient than traditional environmental policies in the protection of the environment technological cooperation moreover can be an important instrument to stabilize international environmental agreements

the effects of soft drink taxes on child and adolescent consumption and weight outcomes abstract childhood and adolescent obesity is associated with serious adverse lifetime health consequences and its prevalence has increased rapidly soft drink consumption has also expanded rapidly so much so that soft drinks are currently the largest single contributors to energy intake in this paper we investigate the potential for soft drink taxes to combat rising levels of child and adolescent obesity through a reduction in consumption our results based on state soft drink sales and excise tax information between 1989 and 2006 and the national health examination and nutrition survey suggest that soft drink taxation as currently practiced in the united states leads to a moderate reduction in soft drink consumption by children and adolescents however we show that this reduction in soda consumption is completely offset by increases in consumption of other high calorie drinks

corruption and air pollution in europe this paper examines how the effectiveness of regulatory framework influences levels of sulphur emissions in a scenario where to reduce its emission tax payments a polluting firm may under report emissions level at the risk of being audited and fined first a model to explain how changes in regulatory framework e g audit effectiveness and transboundary spillovers affect both actual and reported emissions is developed then the theoretical predictions using data for 39 european countries from 1999 to 2003 are tested and inferences about true emission levels are made the empirical analysis supports the theoretical predictions with significant implications for the interpretation of pollution data reported to international monitoring agencies countries with effective regulation are likely to have relatively high reported emissions of sulphur but this should not automatically be interpreted as weak environmental performance because their actual pollution levels are likely to be lower than in nations with less effective regulation

hedonic prices property values and measuring environmental benefits a survey of the issues this paper provides a review of the theoretical basis and the assumptions required in order to use hedonic price equations derived from property value data to obtain measures of the prices and the inverse demand functions for environmental amenities such as air quality it also includes a review and assessment of existing empirical applications of the technique to problems of air and water quality and urban noise

conditional cooperation and climate change it is widely believed that international cooperation can arise through strategies of reciprocity in this paper we investigate whether citizens in the united states and 25 other countries support reciprocity to deal with climate change we find little public enthusiasm for intrinsic reciprocity in which countries restrain their consumption of fossil fuels if and only if other countries do the same in contrast we find significant support for extrinsic reciprocity in which countries enforce cooperation by linking issues citizens support economic sanctions against polluters and are willing to shame them in international forums especially when the polluters are violating a treaty cooperation could therefore emerge from efforts to link climate with other issues and to embed climate commitments in international law

international emission permit markets with refunding we propose a blueprint for an international emission permit market such as the eu trading scheme each country decides on the amount of permits it wants to offer a fraction of these permits is grandfathered the remainder is auctioned revenues from the auction are collected in a global fund and reimbursed to member countries in fixed proportions we show that international permit markets with refunding lead to outcomes in which all countries tighten the issuance of permits and are better off compared to standard international permit markets if the share of grandfathered permits is sufficiently small we obtain approximately socially optimal emission reductions

the structure of the climate debate first best climate policy is a uniform carbon tax which gradually rises over time civil servants have complicated climate policy to expand bureaucracies politicians to create rents environmentalists have exaggerated climate change to gain influence other activists have joined the climate bandwagon opponents to climate policy have attacked the weaknesses in climate research the climate debate is convoluted and polarized as a result and climate policy complex climate policy should become easier and more rational as the paris agreement has shifted climate policy back towards national governments changing political priorities austerity and a maturing bureaucracy should lead to a more constructive climate debate

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

coalitions in transboundary pollution reduction during emission reductions countries render services to each other by reducing transboundary pollution which should be recognized as an additional source of benefit since transboundary pollution fluxes are often significant the underestimation of this factor can substantially affect the choice of emission reduction strategies and eventually restrain pollution reduction this factor is a specific feature of the transboundary pollution problem that in the taxonomy of m iler 1990 relates to the case of regional reciprocal externalities cooperation in the case of regional reciprocal externalities has been often studied explicitly or implicitly in terms of cooperative games with transferable utilities tu one reason for this is that within this approach side payments are allowed which theoretically give higher gains to participants as compared to the approach with non transferable utilities ntu another reason is that the theory of ntu games is not yet sufficiently developed as compared with the theory of tu games but the standard tu approach to regional environmental regulation shows significant drawbacks discussing the analyses of the canadian american agreement on the columbia river by krutilla 1966 1968 and of the mexican american agreement on the colorado river by kneese 1988 m iler 1990 points out that the countries do not use side payments in the explicit form moreover the amounts of implicit side payments seem to be in contradiction with the criteria of economic benefits producing an impression of irrationality of the countries choices mner 1990 in this paper the tu approach is abandoned in favour of the ntu approach to treat the case of regional reciprocal externalities from the viewpoint of the ntu game an irrational behaviour of a participant occurs when his preferences involve hidden goals while his implicit side payments favourably affect the other participants expected choices of strategies with respect to these hidden goals the ntu approach becomes immune to irrational behaviour if it allows consideration of the participants utilities reflecting their respective hidden goals through the above mechanism of transposed preferences non transferability of utilities generally means incommensurability of

thinking economically about climate change abstract uncertainty over both the regional impacts and timing of climatic changes the way they tend to magnify the likelihood of so called natural disasters and their irreversibility require careful analysis of policy options from an economic standpoint the best approach is to apply cost benefit thinking the essential trade off is between doing nothing now and investing in either important preventive or adaptive measures the choices involve analysis of incurring costs now against the benefits of reducing vulnerability and future damage costs for any given level of warming the aim is to minimize the sum of policy costs and costs of adaptation by individuals any resulting policy decision will have to address issues of international cooperation and compensation these considerations may in turn influence the resulting policy choices between carbon taxes marketable permits and regulatory restrictions

market structure and incomplete information price formation in a real world repeated english auction abstract this paper examines the effect of buyer size on price formation in an english auction of used state police cars while open auctions generally favor competitive pricing bikhchandani 1988 develops a model of a second price common value auction in which bidders can use strategic behavior based on repeated sales to develop an aggressive reputation and as a result pay lower prices in equilibrium the paper tests this hypothesis by examining sales of 340 used automobiles sold at 13 public auctions conditional on the volume of purchases made by the three largest buyers at the auctions the empirical results show that the number of buyers plays a stronger role in price formation than does buyer size

bidding behaviour in second price auctions rare stamp sales 1923 1937 we find significant asymmetries between bid functions of the low and high mail bidders in auctions of rare stamps over the extremes of the business cycle 1923 1937 we also find a strong negative relationship between the number of bidders and the bids suggesting that the common value characteristics of stamps outweigh their private value characteristics finally we show that stamp returns are positively related to inflation and to stock yields and negatively to interest rates these last results correspond to other studies of stamps over more stable sample periods

child auctions in nineteenth century sweden an analysis of price differences during the nineteenth century destitute and or orphan swedish children were boarded out as a part of that time s public assistance the families to which they were allocated were determined by means of english auctions this paper studies the price differences among such children using empirical data from 601 auctions price is regressed on variables related both to the buyer and to the child the results suggest that variables related to the children s characteristics were important and that the willingness to take a poor or orphan child was dependent on the foster parents uses for a child in the household children who were old enough to be used as shepherd boys or girls were easily placed it was worse with those who were feeble incapacitated blind sick mentally deranged or confined to their beds they were useless to farmers and others as a rule the most miserable were boarded out to the poorest of the non property owners julius ejdestam 1969 the poor s sweden my translation
