how should commodities be taxed market structure product heterogeneity and the optimal structure of commodity taxes abstract this paper is concerned with the form in which commodity taxes are best imposed and particularly with the appropriate balance between specific and ad valorem components this neglected issue is of policy importance in relation to the harmonization of tax structures within the eec and of theoretical interest as a point of contact between optimal tax theory and models of non price competition the roles of the two taxes as purely corrective devices under a variety of market forms are established and discussed the analysis suggests that heavily taxed commodities should normally be subject to high specific rather than high ad valorem taxes

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

toward a broadened theory of preference formation and the diffusion of innovations cases from zinder province niger republic the standard model for the diffusion of innovations in consumer behavior does not adequately account for the incorporation of novel items of non local origin into the material culture inventory of hausa speaking peasants in niger a synthetic culturally relative model composed of elements drawn from the standard diffusion paradigm from world systems theory and from economic and symbolic anthropology provides a more satisfactory account of these processes analysis shows that novel goods provide a medium through which alternative paradigms of consumer behavior and reality contend among the hausa a premarket model a western market mediated model and an islamic ethnonationalist model compete for consumer affiliation

the long run fisher relation in canada in this paper the existing fisher equation research is extended to time series on the canadian nominal interest rate and inflation to test the validity of the fisher hypothesis and related hypotheses the evidence suggests a significant long run equilibrium between nominal rates and inflation in canada but that this relationship has not been completely stable over the last three decades

the triumph of monetarism the story of 20th century macroeconomics begins with irving fisher in his books appreciation and interest 1896 the rate of interest 1907 and the purchasing power of money 1911 fisher fueled the intellectual fire that became known as monetarism but what has happened to monetarism at the end of the 20th century the short answer is that much of this current of thought is still there but its insights pass under another name we may not all be keynesians now but the influence of monetarism on how we all think about macroeconomics today has been deep pervasive and subtle why then do we today talk much more about the new keynesian economists than about the new monetarist economists i believe that to answer this question we need to look at the history of monetarism over the 20th century one fruitful way to look at the history of monetarism is to distinguish between four different variants or subspecies of monetarism that emerged and for a time flourished in the century just past first monetarism old chicago monetarism high monetarism and political monetarism

retrospectives irving fisher s appreciation and interest 1896 and the fisher relation irving fisher s monograph appreciation and interest 1896 proposed his famous equation showing expected inflation as the difference between nominal interest and real interest rates in addition he drew attention to insightful remarks and numerical examples scattered through the earlier literature and he derived results ranging from the uncovered interest arbitrage parity condition between currencies to the expectations theory of the term structure of interest rates

indirect taxation and cournot equilibrium we analyse a cournot model of oligopoly in an industry which is subject to indirect taxation we consider value added as well as excise taxes we allow for various types of demand and cost conditions as well as cost differences across firms as the tax is raised two types of outcomes can prevail on the one hand the net price can increase which is shown to lead to an increase in market share of high cost firms on the other hand the net price can fall in which case efficiency is rewarded in that low cost firms gain market share this latter outcome which accords with intuition will obtain in most instances it is more likely to occur i with vat rather than with an excise tax ii with concave rather than convex demand and iii with decreasing rather than increasing marginal cost finally we show that an increase in vat can lead to higher profits for low cost firms provided cost differences across firms are large enough

are flexible taxation mechanisms effective in stabilizing fuel prices an evaluation considering wholesale fuel markets in this paper we study the incidence of specific taxes in the italian fuel markets and exploit these findings to simulate the effects of fiscal policies aimed at mitigating oil price fluctuations we estimate several reduced form specifications using as dependent variables the equilibrium wholesale prices for gasoline and motor diesel over the period 1996 2007 in particular we assess the impact on wholesale gasoline and motor diesel prices stemming from the creation of an automatic fiscal mechanism consisting of reductions in specific taxes matching the rise in oil prices our simulations suggest that flexible taxation mechanisms could not be a proper policy for stabilizing price levels in fuel markets a more effective control on prices can be obtained by focusing on the market structure of these industries where antitrust authority could play a significant role

sticky prices inventories and market power in wholesale gasoline markets a model with costly adjustment of production and costly inventories implies that wholesale gasoline prices will respond with a lag to crude oil cost shocks unlike explanations that rely upon menu costs imperfect information or long term buyer seller relationships this model predicts that futures prices for gasoline will adjust incompletely to crude oil price shocks that occur close to the expiration date of the futures contract we test and confirm this implication examining wholesale price responses in 188 gasoline markets we also find that firms with market power adjust prices more slowly than do competitive firms consistent with the model

irving fisher and the fisher relation setting the record straight william j crowder 1997 1124 1127 states that the fisher hypothesis represents one of the oldest and most basic equilibrium relationships in financial economics the fisher equation encapsulates the simple relationship hypothesized to exist between nominal interest rates and expected inflation first delineated by irving fisher 1930 whose name has been associated with the equation ever since crowder s first sentence is indisputable the other sentence quoted presents a belief that seems almost universal in the literature on the fisher relation as distinct from the history of economic thought literature about irving fisher it credits fisher with one of the few innovations in the area for which he does not deserve and did not claim credit neglects what he did contribute on related topics and views the theory of interest 1930 as his first presentation of the relationship a third of a century later than his classic reformulation of the relation the celebrated equation which appears in fisher s american economic association monograph appreciation and interest 1896 and in an appendix to his the rate of interest 1907 does not appear in the theory of interest where the treatment of the relation in chapters 2 and 19 is verbal supplemented with diagrams but no equation in appreciation and interest 1896 fisher drew attention to statements by william douglass john stuart mill alfred marshall jacob de haas and john bates clark of how expected inflation or deflation affects nominal interest and he made no claim to originality on the point writing at the end of a thirty year period of declining prices fisher referred in his title to appreciation of the purchasing power of money rather than to depreciation fisher was the first to write down the relation as an equation but not the first to articulate the relation while endorsing

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

free entry and social inefficiency our goal is to provide a simple yet general exposition of the conditions under which the number of entrants in a free entry equilibrium is excessive insufficient or optimal our analysis compares the number of firms that enter a market when there is free entry with the number that would be desired by a social planner who is unable to control the behavior of firms once they are in the market that is we consider the second best problem of choosing the welfare maximizing number of firms while we take as given their noncompetitive behavior after entry we demonstrate that the crucial conditions for establishing the presence of an entry bias can be stated quite simply in terms of the outcome of the postentry game played by entrants in contrast to previous work we do not need to model this postentry game explicitly

tax incidence under imperfect competition comment abstract delipalla and o donnell 2001 contains a formula for the incidence of specific and ad valorem taxes in a conjectural variation oligopoly model with potentially asymmetric firms the formula is incorrect we derive the correct formula and provide a discussion of the error and its implications for empirical studies of pass through

should we resurrect tipp flottante if oil price booms again specific taxes as fuel consumer price stabilizers abstract as an answer to soaring oil prices stabilization mechanisms based on specific taxes such as the french tipp flottante have been discussed and introduced in some countries in early 2000s but then soon abandoned our contribution aims at analyzing the excise pass through and the cost shifting in a comprehensive european context to understand whether such a mechanism could actually reach its target our results show that on average fuel tax reductions are effective in stabilize consumer price but the measure is particularly costly for public budgets

demythologizing consumption practices how consumers protect their field dependent identity investments from devaluing marketplace myths marketplace myths are commonly conceptualized as cultural resources that attract consumers to a consumption activity or brand this theoretical orientation is prone to overstating the extent to which consumers identity investments in a field of consumption are motivated by an associated marketplace myth we provide a theoretical corrective to this tendency by investigating consumers who have become vested in a commercially mythologized consumption field through an incremental process of building social connections and cultural capital for these consumers the prevailing marketplace myth is experienced as a trivialization of their aesthetic interests rather than as a source of identity value in response they employ demythologizing practices to insulate their acquired field dependent social and cultural capital from devaluation our findings advance theorizations concerning marketplace myths and consumer identity work and explicate the sociocultural forces that deter consumers from abandoning a consump

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

oligopolistic competition and economic welfare a general equilibrium analysis of entry regulation and tax subsidy schemes abstract two contributions to the general equilibrium analysis of an oligopolistic economy with free entry are intended first we generalize the excess entry theorem to the effect that a marginal decrease in the number of oligopolistic firms from the free entry equilibrium level improves economic welfare second we explore the pareto improving tax subsidy schemes in an oligopolistic economy several self financing and pareto improving tax subsidy schemes will be identified in contrast with the preceding analysis by atkinson and stiglitz which focused on the long run incidence of corporate taxation we analyse the short run as well as long run welfare implications of various policies under generalized conditions

tax incidence under oligopoly a comparison of policy approaches abstract this paper presents a methodological approach for the analysis of tax incidence that encompasses familiar forms of taxation in a general and analytically convenient model in oligopolistic industries the performance of a tax depends on the sensitivity of the unit tax rate to changes in industry output output elastic tax schedules are less likely to be over shifted and have superior welfare properties relative to regulatory instruments that are less responsive to the equilibrium market quantity for revenue neutral tax reforms the finding of delipalla and keen 1992 that ad valorem taxes welfare dominate specific taxes under oligopoly is derived as a special case of this general result

incidence of federal and state gasoline taxes the federal specific gasoline tax falls equally on consumers and wholesalers whereas state specific taxes fall almost entirely on consumers the consumer incidence of state taxes is greater in states that use relatively little gasoline

econometric models of asymmetric price transmission abstract in this paper we review the existing empirical literature on price asymmetries in commodities providing a way to classify and compare different studies that are highly heterogeneous in terms of econometric models type of asymmetries and empirical findings relative to the previous literature this paper is novel in several respects first it presents a detailed and updated survey of the existing empirical contributions on price asymmetries in the transmission mechanism linking input prices to output prices second this paper presents an extension of the traditional distinction between long run and short run asymmetries to new categories of asymmetries such as contemporaneous impact distributed lag effect cumulated impact reaction time equilibrium and momentum equilibrium adjustment path regime effect regime equilibrium adjustment path each empirical study is then critically discussed in the light of this new classification of asymmetries third this paper evaluates the relative merits of the most popular econometric models for price asymmetries namely autoregressive distributed lags partial adjustments error correction models regime switching and vector autoregressive models finally we use the meta regression analysis to investigate whether the results of asymmetry tests are not model invariant and find which additional factors systematically influence the rejection of the null hypothesis of symmetric price adjustment the main results of our survey can be summarized as follows i each econometric model is specialized to capture a subset of asymmetries ii each asymmetry is better investigated by a subset of econometric models iii the general significance of the f test for asymmetric price transmission depends mainly on characteristics of the data dynamic specification of the econometric model and market characteristics overall our empirical findings confirm that asymmetry in all its forms is very likely to occur in a wide range of markets and econometric models

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

market power vertical integration and the wholesale price of gasoline this paper examines empirically the relationship between vertical integration and wholesale gasoline prices we use discrete and differential changes in the extent of vertical integration generated by mergers in west coast gasoline refining and retailing markets to test for incentives to raise rivals costs the research design allows us to test for a relationship between vertical integration and wholesale prices controlling for horizontal market structure cost shocks and trends we find evidence consistent with the strategic incentive to raise competitors input costs this suggests that vertical integration can have a significant impact on wholesale prices

nonmonotonic status effects in new product adoption we investigate how the tendency to adopt a new product independently of social influence the recipients susceptibility to such influence and the sources strength of influence vary with social status leveraging insights from social psychology and sociology about middle status anxiety and conformity we propose that for products that potential adopters expect to boost their status both the tendency to adopt independently from others and the susceptibility to contagion is higher for middle status than for low and high status customers applying a nested case control design to the adoption of commercial kits used in genetic engineering we find evidence that status affects i how early or late one adopts regardless of social influence ii how susceptible one is to such influence operating through social ties and iii how influential one s own behavior is in triggering adoption by others the inverse u patterns in i and ii are consistent with middle status anxiety and conformity the findings have implications for how to use status to better understand adoption and contagion mechanisms and for targeting customers when launching new products

toward a theory of status consumption in less industrialized countries how does status consumption operate among the middle classes in less industrialized countries lics those classes that have the spending power to participate effectively in consumer culture globalization research suggests that bourdieu s status consumption model based upon western research does not provide an adequate explanation and what we call the global trickle down model often invoked to explain lic status consumption is even more imprecise we study the status consumption strategies of upper middle class turkish women in order to revise three of bourdieu s most important concepts cultural capital habitus and consumption field to propose a theory specific to the lic context we demonstrate that cultural capital is organized around orthodox practice of the western lifestyle myth that cultural capital is deterritorialized and so accrues through distant textbook like learning rather than via the habitus and that the class faction with lower cultural capital indigenizes the consumption field to sustain a national social hierarchy

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

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

unit versus ad valorem taxes monopoly in general equilibrium abstract we show that if a monopoly sector is imbedded in a general equilibrium framework and profits are taxed at one hundred percent then unit specific taxation and ad valorem taxation are equivalent on the set of pareto optima

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

do gasoline prices respond asymmetrically to crude oil price changes the authors test and confirm that retail gasoline prices respond more quickly to increases than to decreases in crude oil prices among the possible sources of this asymmetry are production inventory adjustment lags and market power of some sellers by analyzing price transmission at different points in the distribution chain the authors attempt to shed light on these theories spot prices for generic gasoline show asymmetry in responding to crude oil price changes which may reflect inventory adjustment effects asymmetry also appears in the response of retail prices to wholesale price changes possibly indicating short run market power among retailers
