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

taxing food and beverages theory evidence and policy we developed a theoretical framework to examine the effect of a change in sales or excise tax on food and beverage demand after considering that consumers may have imperfect tax knowledge are sometimes inattentive to sales tax may not be informed of a sales tax change and pay no sales tax on eligible food or beverages if using food stamps we conducted simulations to assess how much the sales tax elasticity of demand should be adjusted downward from the price elasticity of demand and quantified the advantage of using an excise tax as an anti obesity policy copyright 2013 oxford university press

do cigarette producers price discriminate by state an empirical analysis of local cigarette pricing and taxation abstract this study analyzes the interactive effects of oligopoly pricing state taxation and anti smoking regulations on retail cigarette prices by state using panel data for the 50 us states between 1960 and 1990 the results indicate that cigarette producers do price discriminate by state though the effect is not large relative to the final retail price there are two further results 1 state taxes are more than passed on a 1 cent state tax increase results in a price increase of 1 11 cents and 2 sellers offset state and local anti smoking laws with lower prices thereby blunting effects of the regulations

vertical control opportunism and risk sharing abstract a manufacturer who offers secret contracts faces an opportunism problem she undercuts her own input prices and fails to offset retail competition i show that this problem diminishes when retailers are risk averse and face demand uncertainty risk aversion and uncertainty create a bilateral risk sharing incentive that raises equilibrium input prices above marginal cost the manufacturer can therefore profit from downstream risk aversion when retail competition is fierce

assessment and optimization of forest biomass supply chains from economic social and environmental perspectives a review of literature abstract forest biomass is a renewable source that has the potential to substitute fossil fuels in many applications from the generation of bioenergy heat electricity or transportation fuels to the production of bioproducts chemicals and other materials the increased use of forest biomass could support the reduction of anthropogenic carbon emissions to the environment and could help forest dependent communities achieve energy independence while generating jobs the viability and feasibility of generating valuable products from forest biomass depend on ensuring the long term availability of biomass supply with the required quality at a competitive cost this calls for a cost efficient design of the forest biomass supply chain social and environmental aspects have to be considered in the design as well to guarantee sustainable use of this renewable resource in this paper we present a review of studies that assessed or optimized economic social and environmental aspects of forest biomass supply chains for the production of bioenergy and bioproducts the majority of studies so far considered either economic techno economic and optimization studies or environmental life cycle assessment studies aspects of bioenergy projects nevertheless there is a recent trend to integrate economic environmental and social aspects in the assessment and optimization of forest biomass supply chains combined approaches integrating multi objective optimization and life cycle assessment have started to flourish in these studies ghg emissions are the most frequently used environmental indicator production and capital costs are the preferred economic measures and the number of created jobs is the most considered social criterion further research has to be done to study and assess the potential social impacts of using forest biomass there is a need for further development of decision support tools that consider economic environmental and social criteria to aid the design and planning of forest biomass supply chains

risk sharing in licensing abstract this paper studies the design of linear license contracts under demand or cost uncertainty the optimal contract consists in general of a mix of a fixed fee and royalties the source of uncertainty has a crucial impact on the type of royalties that must be used in particular under demand uncertainty at most two of the instruments are used the contract generally combines a fixed fee with an ad valorem royalty when cost is uncertain a wider variety of cases can arise the contract may involve a combination of either type of royalties coupled with a fixed fee alternatively it may be optimal to use all three available instruments

excise gap and price in the italian cigarette industry we provide evidence that tax shifts in the italian cigarette industry are not homogeneous across price categories and are associated with differences in the excise structure we take the gap betwee

vertical integration and firm boundaries the evidence since ronald h coase s 1937 seminal paper a rich set of theories has been developed that deal with firm boundaries in vertical or input output structures in the last twenty five years empirical evidence that can shed light on those theories also has been accumulating we review the findings of empirical studies that have addressed two main interrelated questions first what types of transactions are best brought within the firm and second what are the consequences of vertical integration decisions for economic outcomes such as prices quantities investment and profits throughout we highlight areas of potential cross fertilization and promising areas for future work

estimating tax incidence market power and market conduct the european cigarette industry abstract recent theoretical work has shown that the incidence of ad valorem and specific taxes may differ and each may be over or under shifted onto consumers in the presence of imperfect competition these results are used to derive a method of estimating market power and conduct an application is made to the european cigarette industry previous empirical comparison of the incidence of ad valorem and specific taxes is limited for a group of countries with broadly similar cigarette industries there is evidence of undershifting of both taxes with the specific tax having a significantly greater impact on price the extremes of both perfect competition and monopoly can be rejected behaviour is no less competitive than the equivalent of cournot

existence and persistence of price dispersion an empirical analysis the hebrew university of jerusalem and nber using a unique data set on store level monthly prices of four homogenous products sold in israel i study the existence and characteristics of the dispersion of prices across stores as well as its persistence over time i find that price dispersion prevails even after controlling for observed and unobserved product heterogeneity moreover intra distribution mobility is significant stores move up and down the cross sectional price distribution thus consumers cannot learn about stores that consistently post low prices as a consequence price dispersion does not disappear and persists over time as predicted by varian s 1980 model of sales

supplier selection order allocation a two stage multiple criteria dynamic programming approach this paper proposes a two stage multiple criteria dynamic programming approach for two of the most critical tasks in supply chain management namely supplier selection and order allocation in the first stage to address multiple decision criteria in supplier ranking the analytic hierarchy process ahp is employed in the second stage supplier ranks are fed into an order allocation model that aims at maximizing a utility function for the firm as well as minimizing the total supply chain costs subject to constraints on demand capacity and inventory levels a dynamic programming approach is crafted to solve the proposed bi objective model

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 renewable portfolio standard design considerations and an implementation survey renewables have social and environmental bene ts compared to conventional electricity sources but are rarely competitive on a strict nancial cost basis this is because conventional sources are sometimes subsidized their full pollution costs are ignored and renewables involve newer higher cost technologies whose relative costs will fall with commercialization governments use several mechanisms to support renewables including direct nancial support grants loans indirect support r d demonstrations reform of nancial costs of conventional sources subsidy removal pollution taxes and the renewable portfolio standard rps the rps requires a minimum share of electricity from renewable energy sources its use is spreading because it maintains an incentive for renewable producers to reduce costs links the regulated market outcome to an environmental target and reduces government involvement although it is too early to evaluate fully its e ectiveness the survey for this study explored implementation issues in three european countries nine us states and australia and found the following the rps target is usually set to have environmental bene ts without causing signi cant price increases cost caps are sometimes used most jurisdictions limit eligibility to gridconnected domestic renewables the rps is usually applied to producers rather than consumers and to energy output not capacity flexibility mechanisms are desired but a challenge to implement administration in the us and australia is by government with delegation to independent utility regulators while in europe it is more the responsibility of government everywhere the rps is applied alongside other mechanisms of renewables support 2001 elsevier science ltd all rights reserved

the plight of the biomass power generation industry in china a supply chain risk perspective abstract for the past several years the biomass power generation industry in china has witnessed notably rapid development however many biomass power generation manufacturers in china are currently making small profits or suffering losses and the entire biomass supply chain does not function well which not only poses a challenge for the stable operation of enterprises but also may impact the smooth development of the biomass power industry from the perspective of supply chain risk this paper explores the reasons for the current plight and the future obstacles that the chinese biomass power generation industry may face identifying such risks as market risk production risk technology risk economic risk and management risk in the upstream midstream and downstream of the biomass supply chain and ordering the degrees of risk controllability by the government and enterprises it is determined that joint effort by both the chinese government and the biomass power generation enterprises is an ideal choice for risk control coming out of the plight however at present more problems should go to the government for solutions than to the enterprises to guide the healthy development of the industry the chinese government should play a more prominent role in promulgating supporting policies in each stage of the supply chain and strengthening the supervision and control of biomass projects last specific measures taken by the chinese government and the enterprises are proposed

effects of changes in italian bioenergy promotion schemes for agricultural biogas projects insights from a regional optimization model italy has witnessed an extraordinary growth in biogas generation from livestock effluents and agricultural activities in the last few years as well as a severe isomorphic process leading to a market dominance of 999 kw power plants owned by entrepreneurial farms under the pressure of the economic crisis in the country the italian government has restructured renewable energy support schemes introducing a new program in 2013 in this paper the effects of the previous and current support schemes on the optimal plant size feedstock mix and profitability were investigated by introducing a spatially explicit biogas supply chain optimization model which accounts for different incentive structures by applying the model to a regional case study homogenization observed to date is recognized as a result of former incentive structures considerable reductions in local economic potentials for agricultural biogas power plants without external heat use are estimated new plants are likely to be manure based and due to the lower energy density of such feedstock wider supply chains are expected although optimal plant size will be smaller the new support scheme will therefore most likely eliminate past distortions but also slow down investments in agricultural biogas plants

competition between biomass and food production in the presence of energy policies a partial equilibrium analysis abstract bioenergy has several advantages over fossil fuels for example it delivers energy at low net co 2 emission levels and contributes to sustaining future energy supplies the concern however is that an increase in biomass plantations will reduce the land available for agricultural production the aim of this study is to investigate the effect of taxing conventional electricity production or carbon use in combination with subsidizing biomass or bioelectricity production on the production of biomass and agricultural commodities and on the share of bioelectricity in total electricity production we develop a partial equilibrium model to illustrate some of the potential impacts of these policies on greenhouse gas emissions land reallocation and food and electricity prices as a case study we use data for poland which has a large potential for biomass production results show that combining a conventional electricity tax of 10 with a 25 subsidy on bioelectricity production increases the share of bioelectricity to 7 5 under this policy regime biomass as well as agricultural production increase a carbon tax that gives equal net tax yields has better environmental results however at higher welfare costs and resulting in 1 to 4 reduction of agricultural production

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

revenue sharing coordination in reverse logistics a reverse supply chain as a post consumption activity aims at extracting value from products at the end of their life cycle it could be comprised of reusing refurbishing remanufacturing and recycling activities in this paper we revisit the issue of revenue sharing in reverse supply chains to formulate the decision problems of coordinating parties manufacturer and retailer the coordination is formed in a dynamic setting where a feedback relationship exists between the return incentive policy of the retailer and the revenue sharing incentive strategy of the manufacturer to model this process we have adopted the use of a system dynamics sd approach sd is well suited for studying the behavior of complex systems over time and where internal feedbacks and delays exist we first identify pareto optimal solutions for individual players and from environmental perspectives of landfill diversion and carbon offset we then focus on revenue sharing as a widely practiced coordination scheme in reverse supply chains it resembles a leader follower stackelberg strategic decision making game with an equilibrium solution that yields lower performance for environmental criteria in this context we investigate if how a revenue sharing mechanism can be coordinated to achieve a higher environmental performance

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

double marginalization and cost pass through weyl fabinger and cowan meet spengler and bresnahan reiss consider the classical double marginalization problem of single product successive monopolies we show that the ratio of the cost pass through at the final sale relative to that at the wholesale level is characterized by the curvature of inverse demand in the final market we also apply cowan s 2012 method which utilizes the idea of pass through in an analysis of third degree price discrimination to compare consumer surplus under vertical integration and separation

economies of scale in biogas production and the significance of flexible regulation abstract biogas production is characterised by economies of scale in capital and operational costs of the plant and diseconomies of scale from transport of input materials we analyse biogas in a danish setting where most biogas is based on manure we use a case study with actual distances and find that the benefits of scale in capital and operational costs dominate the diseconomies of increasing transport distances to collect manure to boost the yield it is common to use co substrates in the biogas production we investigate how costs and income changes when sugar beet is added in this case study and demonstrate that transport cost can be critical in relation to co substrates further we compare the new danish support for upgraded biogas with the traditional support for biogas being used in combined heat and power production in relation to scale economies we argue that economies of scale is facilitated by the new regulation providing similar support to upgraded biogas fed into the natural gas grid however in order to keep transport costs low we suggest that the biogas plants should be allowed to use and combine as many co substrates as possible respecting the sustainability criteria regarding energy crops in danish legislation

optimal design of supply chains for second generation biofuels incorporating european biofuel regulations abstract expected changes in european biofuel regulations lead to uncertainty in supply chain planning for second generation biofuel industries previous studies used optimization to design biofuels supply chains and a few of them analyzed the impact of selected biofuel policy instruments on sustainability targets this study presents a mixed integer programming model for the optimal design of second generation biofuel supply chains considering all policy instruments of european biofuel regulations the model maximizes the net present value of second generation biofuel supply chains considering time dependent quotas for biofuel market shares and greenhouse gas emission savings the model includes multiple counting of second generation biofuel towards meeting biofuel market share targets and captures all greenhouse gas emissions of the second generation biofuel supply chain including land use change emissions we demonstrated the use of the model through the case study of second generation biodiesel in a german region and evaluated the sensitivity of the optimal solution to model parameters and policy instruments levels a set of remarks were made regarding the impact of policy instruments on the performance of second generation biodiesel supply chain under study future work entails the application of the analysis to the aggregate level in the european union

contracting with externalities the paper studies inefficiencies arising in contracting between one principal and n agents when the utility of each agent depends on all agents trades with the principal when the principal commits to a set of publicly observable bilateral contract offers the arising inefficiency is due entirely to the externalities imposed on non signers in contrast when the principal s offers are privately observed the distortion is due to the externalities given agents equilibrium trades comparison of the two externalities determines the relative efficiency of the two contracting regimes in both cases we show that when n is large each agent can be treated as non pivotal provided that appropriate continuity assumptions are satisfied we also study the case in which the principal can condition each agent s trade on other agents messages we characterize the set of such mechanisms in which each agent s participation is voluntary when the principal can commit to any such mechanism she implements the first best outcome while threatening each deviator with the harshest possible punishment however in the presence of noise that goes to zero slower than n goes to infinity in the limit we obtain a generally inefficient outcome in which each agent feels non pivotal

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

efficient excise taxation the evidence from cigarettes we develop a model in which optimizing policy makers in adjacent government jurisdictions levy excise taxes on a commodity that has a unique point of production from which all shipments emanate from this model we derive an unusually specific predicted geographical pattern of those excise taxes in which these taxes rise at a decreasing rate as one moves outward from the point of production we compare these predictions to the observed pattern of cigarette taxes imposed by state governments in the united states and find the data to be fully consistent with our model among these predictions is the existence of a ripple effect which reduces taxes in many other jurisdictions due to low taxes at the point of production we estimate that these induced tax reductions in other states save cigarette producers and consumers a minimum of 110 million per year

consumption taxes in a life cycle framework are sin taxes regressive we construct measures of tax incidence over the life cycle and compare these measures to traditional measures based on annual data annual measures of the incidence of taxes on consumption goods may differ from life cycle measures for three reasons first annual measures of income reflect transitory components which should have smaller effects on consumption than permanent changes in income second income measured in a single period differs from lifetime income due to age related differences in earnings third consumption of certain items follows life cycle patterns independent of changes in income surprisingly we find that these effects cause little change in the assessment of the incidence of taxes on cigarettes for alcohol we find that a tax on its consumption is slightly less regressive when measured with respect to lifetime income than when measured with respect to annual income copyright 1995 by mit press

supply chain and logistics issues of bio energy production abstract within the concert of renewable energy technologies bio energy can play a decisive role during the next decades when smartly designed and applied under favorable conditions in this respect efficient and effective supply chain and logistics management represent one key parameter this paper presents a literature review of articles published in english speaking peer reviewed journals from 2000 to 2009 which cover the interface of bio energy production and issues of logistics and supply chain management first the articles are assessed according to descriptive criteria such as journal year of publication and research design applied then issues and challenges of designing and operating biomass chains that secure stable and competitively priced feedstock supply for bio energy plants have been classified 1 into the operations harvesting and collection storage transport and pre treatment techniques as well as 2 into overall supply system design although biomass supply chains for energy use are manifold in terms of size design and functioning most relevant issues regarding supply chain management and logistics of bio energy production are identified the findings are discussed against the backdrop of bio energy as sustainable renewable energy option

opportunism in multilateral vertical contracting nondiscrimination exclusivity and uniformity comment an input supplier selling to competing downstream firms would benefit from publicly committing at the outset to all contracts efficient commitment however would require complete contracts the authors study instead bilateral contracting without commitment regarding others terms each firm then fears that the supplier might opportunistically renegotiate another s contract to increase bilateral profit at the firm s expense the authors show that nondiscrimination clauses generally cannot curb such third party opportunism even with symmetric firms to reassure firms crude forms of commitment may be adopted this could explain the pervasiveness of exclusivity arrangements and the striking uniformity and intertemporal rigidity of franchise contracts copyright 1994 by american economic association

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

developing a sustainability framework for the assessment of bioenergy systems the potential for biomass to contribute to energy supply in a low carbon economy is well recognised however for the sector to contribute fully to sustainable development in the uk specific exploitation routes must meet the three sets of criteria usually recognised as representing the tests for sustainability economic viability in the market and fiscal framework within which the supply chain operates environmental performance including but not limited to low carbon dioxide emissions over the complete fuel cycle and social acceptability with the benefits of using biomass recognised as outweighing any negative social impacts this paper describes an approach to developing a methodology to establish a sustainability framework for the assessment of bioenergy systems to provide practical advice for policy makers planners and the bioenergy industry and thus to support policy development and bioenergy deployment at different scales the approach uses multi criteria decision analysis mcda and decision conferencing to explore how such a process is able to integrate and reconcile the interests and concerns of diverse stakeholder groups

modeling of biomass to energy supply chain operations applications challenges and research directions reducing dependency on fossil fuels and mitigating their environmental impacts are among the most promising aspects of utilizing renewable energy sources the availability of various biomass resources has made it an appealing source of renewable energy given the variability of supply and sources of biomass supply chains play an important role in the efficient provisioning of biomass resources for energy production this paper provides a comprehensive review and classification of the excising literature in modeling of biomass supply chain operations while linking them to the wider strategic challenges and issues with the design planning and management of biomass supply chains on that basis we will present an analysis of the existing gaps and the potential future directions for research in modeling of biomass supply chain operations

green logistics and national scale economic indicators evidence from a panel of selected european countries abstract the objective of the study is to examine the impact of logistics performance indices on national scale economic indicators i e energy environment and economic health in a panel of 27 european countries over a period of 2007 2014 the results show that logistics performance index in terms of timeliness significantly increases gdp per unit of energy use health expenditures and per capita income where as logistics index in terms of infrastructure increases renewable energy source and decreases carbon emissions logistics index for customs processes significantly associated with the less energy prices while logistics index for tracking and trace consignments substantially increases fossil fuel energy consumption logistics competence index have a differential impact on environment on one hand it substantially reduce the burden of fossil fuel energy consumption while on the other hand it s significantly increases carbon emissions logistics international shipments increase fossil fuel energy in a region industry value added and fdi inflows both increases energy prices fossil fuel energy health expenditures and per capita income whereas trade openness decreases energy prices and increases carbon emissions energy efficiency and per capita income the results conclude that logistics indices significantly linked with the national scale economic indicators that provoke for the green supply chain management in the region

an economic theory of vertical restraints vertical restraints imposed by manufacturers on the prices locations and sales of retail firms represent a puzzling departure from the simple price mediated exchange of conventional markets in this article we analyze the theoretical basis for these restraints in a setting where retailers inform consumers and are imperfectly competitive and where a manufacturer has some monopoly power we identify three potential externalities affecting retailers decisions these externalities lead to the failure of simple uniform price contracts to coordinate the incentives of retailers with the objective of maximizing combined manufacturer and retailer profits we identify the packages of vertical restraints that are minimally sufficient under various conditions to neutralize the externalities and to achieve the joint profit maximum

commodity taxation and imperfect competition a note on the effects of entry abstract this paper looks at the effects of allowing the number of firms to vary in seade s model of oligopoly and taxation we show that the normative and positive consequences of a specific commodity tax are affected by entry in significant ways

perfect competition urbanization and tax incidence in the retail gasoline market i introduction in applied tax incidence studies it is typically assumed that prices respond one for one to changes in sales and excise taxes chernick and reschovsky 1997 pechman 1985 shepard 1976 state of wisconsin department of revenue 2004 wiese rose and schluter 1995 zupnick 1975 is this assumption reasonable despite the fundamental role of tax incidence in the study of public finance there is surprisingly little empirical analysis that sheds light on who bears the burden of taxes in this article we examine the incidence of state gasoline excise taxes using monthly price data for all 50 states in the united states over the period 1984 1999 our estimation results generally indicate full shifting of gasoline taxes to the final consumer with changes in gasoline taxes fully reflected in the tax inclusive gasoline price almost instantly we also find that the incidence of excise taxes depends on the competitiveness of retail gasoline markets e g urban vs rural markets gasoline markets in urban states typically exhibit full shifting but those in rural states demonstrate somewhat less than full shifting although the issue of sales and excise tax incidence has received considerable attention over the years most research has focused on tax incidence theory and the standard conclusion of much of this theoretical analysis is that consumers bear the full burden of any sales and excise taxes 1 based primarily on this theoretical foundation most applied incidence studies assume that sales and excise taxes are fully reflected in consumer prices and the distribution of tax burdens across income classes necessarily reflects this assumption however actual empirical testing of this assumption of full forward shifting has been surprisingly sparse 2 in important recent research poterba 1996 and besley and rosen 1999 have conducted empirical analyses of the incidence of excise taxes poterba 1996 uses city specific clothing and personal care price data covering the 1947 1977 and the 1925 1939 periods to examine the degree to which state and local retail sales taxes are shifted to consumers with two data sets based on bureau of labor statistics bls city specific consumer price indices using these bls data on tax inclusive prices poterba 1996 constructs quarterly price indices for each of 28 standard metropolitan statistical areas smsas many of these 28 smsas experienced significant changes in sales tax rates and poterba 1996 uses these tax shocks to determine the incidence of sales taxes his estimation results are somewhat variable but in general he finds for the postwar period that taxes are fully shifted to consumers in some cases he finds limited evidence of overshifting although it is never possible to reject the null hypothesis that prices rise point for point with the changes in the tax and he also finds that full shifting typically though not always occurs in the first quarter of the tax change poterba 1996 also examines tax incidence for individual smsas during the depression era and his results indicate significant differences across metropolitan areas in the degree of tax shifting for example prices on women s clothing in chicago show significant overshifting but atlanta shows negative shifting a result that does not seem plausible besley and rosen 1999 also examine the incidence of sales taxes using price data for 12 narrowly defined commodities in 155 different u s cities using quarterly price data for the period 1982 1990 issued by the american chamber of commerce researchers association accra 3 they not only find full shifting for a number of commodities but also find overshifting for more than half the products a result they attribute to imperfect competition in the retail sector while this recent empirical research has significantly expanded our understanding of the actual nature of sales and excise tax incidence we believe that our work here on gasoline excise taxes makes several contributions to the empirical literature

an exploratory game theoretic analysis of biomass electricity generation supply chain this study proposes a game theoretic approach to model and analyze the process of utilizing biomass for power generation considering three players distributor facility developer and participating farmer we characterize the nash equilibrium of the sequential game and discuss its features a special attention is devoted to the analysis of the impact of incentives and initial target on the equilibrium in which the biomass is part of electricity production

consumption taxes and corporate investment consumers nominally pay the consumption tax but theoretical and empirical evidence is mixed on whether corporations partly shoulder this burden thereby affecting corporate investment using a quasi natural experiment we show that consumption taxes decrease investment firms facing more elastic demand decrease investment more strongly because they bear more of the consumption tax we corroborate the validity of our findings using 86 consumption tax changes in a cross country panel we document two mechanisms underlying the investment response reduced firms profitability and lower aggregate consumption importantly the magnitude of the investment response to consumption taxes is similar to that of corporate taxes received september 25 2017 editorial decision august 26 2018 by editor wei jiang authors have furnished an internet appendix which is available on the oxford university press web site next to the link to the final published paper online

tax changes and cigarette prices the recurring question of the difference between specific and ad valorem taxes has recently been revived by barzel 1976 who argued p 1185 that when quality is not fully controlled the effects of the two types of taxes differ radically the excise tax induces a substitution of quality for quantity resulting in a greater increase in the price per unit than predicted by the constant quality model the ad valorem tax induces a reduction in quality and lower after tax price than predicted evidence consistent with these hypotheses is found in the response of cigarette prices to tax changes in the further tests reported by johnson 1978 prices rise significantly less than the tax in new hampshire where the state tax was ad valorem and significantly more in the remaining states which impose specific taxes the purpose of this note is to question not barzel s analysis but rather the interpretation of the evidence on the pedestrian grounds of implausibility as barzel himself observes p 1194 n 32 the size of new hampshire makes it unlikely that cigarettes would be tailormade for it the scope for removing characteristics is quite limited then the scope for adding characteristics in other states seems equally limited to avoid misunderstanding it should be emphasized that the hypothesized variations in quality are a supply side phenomenon not a demand side response to the relative cheapening of superior brands when a specific tax is increased johnson s estimates imply that the 90 increase in the new hampshire tax over the period 1954 76 should have reduced the net price by 3 6 ceteris paribus the slightly larger mean tax increase in the remaining 48 continental states should have raised net price by 0 90 what changes in the quality of the services sold with cigarettes could have justified such a differential what are the observable counterparts of the tax changes in the absence of a convincing answer to those questions the estimated response of cigarette prices to taxes represents a fact in search of a theory

bilateral control with vertical contracts when a manufacturer contracts secretly with competing retailers he is subject to opportunism and linear or non linear tariffs may not allow the manufacturer to maintain monopoly prices to analyse the effects of rpm o brien shaffer 1992 use a concept of contract equilibrium which concentrates on pairwise deviations thereby questioning the robustness of the analysis this paper emphasises the distinction between the contract equilibrium and standard non cooperative concepts we advocate for some caution in the use of the former concept as if overlooks an inexistence problem we then confirm the intuition that rpm can help solve the manufacturer s commitment problem this confirms that o brien shaffer s insight is robust and validates the courts reluctance against rpm

how to model different socio economic and environmental aspects of biomass utilisation case study in selected regions in slovenia and croatia abstract wood biomass is an important renewable source of energy especially in countries with traditional dependency on forestry resources in these countries wood biomass can have numerous positive socio economical and environmental effects this paper presents a new model score model for estimation of 15 socio economic and environmental aspects of increased use of biomass from the forests the presented model enables selected estimation of different aspects in the whole chain of biomass production preparation and use namely the model enables the estimation of net labour income net profit regional public finance income net direct jobs net indirect jobs net induced jobs total net jobs contribution to forest management impact on wood waste utilisation impact on other woody biomass utilisation avoided costs of landfill saving co2 emissions possible impact on regional unemployment avoided costs of unemployment additional jobs for farmers additional activities on farms from indirect and induced jobs and self sufficiency in electricity production the score model was tested in selected regions in slovenia and croatia and apart from a good understanding of the socio economic and environmental aspects it also enables an overview of the economy of wood biomass production given that it includes the economic analysis of wood biomass production and use the model is not intended for a detailed economic analysis of separate phases of wood biomass production processing and use but particularly to show advantages or disadvantages that can result from planned and existing biomass systems
