re examination of uniform commodity taxes under a non linear income tax system and its implication for production efficiency abstract this paper shows that the result of uniform commodity tax under nonlinear income taxation by atkinson and stiglitz 1976 no longer holds if the production side of an economy is taken into the consideration in particular imposing a non uniform commodity tax can pareto improve welfare even under nonlinear income taxation in addition the paper shows that if the government uses a nonlinear income tax system for income redistribution then the introduction of distortions in the public sector can pareto improve welfare contrary to the results in diamond and mirrlees 1971

new technology adoption in us telecommunications the role of competitive pressures and firm level inducements in this study we examine the reasons for the differential adoption levels of a new technology that of electronic switching across firms in the us telecommunications industry using theoretical postulates from the market structure inducements approach to firm behavior and the behavioral theory of the firm we propose that the incentives to adopt a new technology are positively related to the competitive pressures faced by a firm in its micro market negatively related to past levels of performance and positively related to slack availability our sample consists of 40 of the largest firms in the industry we use firm level data collected for the years 1973 1978 1981 1984 and 1987 and the results indicate strong support for our proposition our findings show that in general market effects via the mechanism of competitive pressures generated are strong in explaining inter firm variations in levels of technology adoption in the period since moves to deregulate the industry began however the firm level effects are equally strong if not stronger in explaining such variations both in the period leading up to the commencement of deregulatory moves and also immediately thereafter

on the undesirability of commodity taxation even when income taxation is not optimal abstract an important result due to atkinson and stiglitz 1976 atkinson a b stiglitz j e 1976 the design of tax structure direct versus indirect taxation journal of public economics 6 55 75 is that differential commodity taxation is not optimal in the presence of an optimal nonlinear income tax given weak separability of utility between labor and all consumption goods this article demonstrates that this conclusion holds regardless of whether the income tax is optimal in particular given any commodity tax and income tax system differential commodity taxation can be eliminated in a manner that results in a pareto improvement also differential commodity taxation can be proportionally reduced so as to generate a pareto improvement in addition for commodity tax reforms that neither eliminate nor proportionally reduce differential taxation a simple efficiency condition is offered for determining whether a pareto improvement is possible

regressive sin taxes with an application to the optimal soda tax a common objection to sin taxes corrective taxes on goods that are thought to be overconsumed such as cigarettes alcohol and sugary drinks is that they often fall disproportionately on low income consumers this paper studies the interaction between corrective and redistributive motives in a general optimal taxation framework and delivers empirically implementable formulas for sufficient statistics for the optimal commodity tax the optimal sin tax is increasing in the price elasticity of demand increasing in the degree to which lower income consumers are more biased or more elastic to the tax decreasing in the extent to which consumption is concentrated among the poor and decreasing in income effects because income effects imply that commodity taxes create labor supply distortions contrary to common intuitions stronger preferences for redistribution can increase the optimal sin tax if lower income consumers are more responsive to taxes or are more biased as an application we estimate the optimal nationwide tax on sugar sweetened beverages using nielsen homescan data and a specially designed survey measuring nutrition knowledge and self control holding federal income tax rates constant our estimates imply an optimal federal sugar sweetened beverage tax of 1 to 2 1 cents per ounce although optimal city level taxes could be as much as 60 lower due to cross border shopping

environmental taxation inequality and engel s law the double dividend of redistribution empirical evidence shows that low income households spend a high share of their income on pollution intensive goods this fuels the concern that an environmental tax reform could be regressive we employ a framework which accounts for the distributional effect of environmental taxes and the recycling of the revenues on both households and firms to quantify changes in the optimal tax structure and the equity impacts of an environmental tax reform we characterize when an optimal environmental tax reform does not increase inequality even if the tax system before the reform is optimal from a non environmental point of view if the tax system before the reform is calibrated to stylized data and is thus non optimal we find that there is a large scope for inequality reduction even if the government is restricted in its recycling options

optimal retail contracts with asymmetric information and moral hazard constrained joint profit maximizing retail contracts are derived when the dealer is privately informed about demand conditions before contracting with the manufacturer demand is increased by dealer promotion which is unobservable by the manufacturer consequently the manufacturer does not know whether to attribute a low level of sales to a decline in demand or to a lack of promotion we show that in general the optimal contract exhibits some form of resale price maintenance and quantity fixing the type of resale price maintenance and quantity fixing depends on how price and quantity affect the link between sales and promotion

the speed of the invisible hand abstract very little attention has been devoted to incorporating dynamic elements into empirical models of market structure and performance consequently there has been little progress in settling the issue of whether the market structure profits relationship is more than just a temporary phenomenon in this study an estimation equation is developed which allows for incomplete adjustment of past profits from expected future profits where expected profits depends on present and expected future changes in market structure the model is estimated pooling panel data across industries the findings indicate that adjustment to abnormal profits is relatively quick market share adjustments are non instantaneous and that inclusion of industry specific effects is important the results suggest that previous studies are susceptible to specification bias from omitted variables

taxing consumption and other sins taxes as their primary tools to collect revenue in the rest of the world governments also use income and payroll taxes but rely much more heavily than does the united states on taxing consumption consumption taxes take many forms including general sales taxes value added taxes and excise taxes on the consumption of specific items including gasoline alcohol tobacco products firearms air travel telephone communication and others the u s government does not use a value added tax making the united states unique among high income countries and a rarity in the larger world as of 2004 at least 134 countries rely on value added taxes as a substantial source of funding value added taxes are sophisticated forms of sales taxes in which taxes are withheld by businesses according to value added at every stage of production american states do impose sales taxes on broad categories of consumer purchases but state governments are considerably smaller than national governments and their sales tax rates are very low compared to the value added tax rates used in the rest of the world the united states also imposes unusually low excise taxes even after controlling for total tax collections which are lower in the united states than they are in most high income countries the deliberate social engineering that underlies the selection of certain commodities for unusually high rates of taxation appeals less to americans than to residents of other countries moreover the sin taxes on

optimal taxation and cross price effects on labor supply estimates of the optimal gas tax abstract this study estimates parameters necessary to calculate the optimal second best gasoline tax most notably the cross price elasticity between gasoline and leisure prior theoretical work indicates the importance of this elasticity but despite this almost none of the prior studies of commodity taxation and none of the studies on second best environmental regulation actually estimate it using household data we find that gasoline is a relative complement to leisure and thus that the optimal gasoline tax is significantly higher than marginal damages the opposite of the result suggested by the bulk of the prior literature indeed even if there were no externalities at all associated with gasoline the optimal tax rate would still be almost equal to the average gas tax rate in the u s following this approach to estimate cross price elasticities with leisure could strongly influence estimates of optimal rates for other important commodity or pollution taxes

a new method of estimating risk aversion i show existing evidence on labor supply behavior places an upper bound on risk aversion in the expected utility model i derive a formula for the coefficient of relative risk aversion in terms of the ratio of the income elasticity of labor supply to wage elasticity and degree of complementarity between consumption and labor i bound the degree of complementarity using data on consumption choices when labor supply varies across states using labor supply elasticity estimates i find a mean estimate of 1 then show generating 2 requires that wage increases cause sharper labor supply reductions jel d81 j22

indirect taxation is superfluous under separability and taste homogeneity a simple proof indirect taxation is of no use when nonlinear income taxation is available in an economy where everyone has the same taste for goods an elementary proof of this result due to atkinson and stiglitz atkinson a stiglitz j 1976 the design of tax structure direct versus indirect taxation journal of public economics 6 55 75 is provided

optimal redistribution when different workers are indistinguishable using the standard non linear income and commodity taxation framework this paper examines the optimal policy to be adopted when the same labor disutility can receive two opposite interpretations taste for leisure and activity limitation in the absence of complete information about individual characteristics an income tax does not allow to distinguish lazy from handicapped individuals one may however rely on a combination of commodity and income taxes to redistribute from the former to the latter when they differ in their preferences for commodities

the determinants of technology adoption the case of the banking firm using data on the adoption of automatic teller machines by firms in the banking industry this study examines the relationship between the decision to adopt new technology and its determinants since banking firms differ considerably in terms of the competitive environments in which they operate focusing on this one innovation in this industry allows a stronger test of the relationship between market structure and the adoption of new technology than has been previously conducted using a failure time estimation procedure we find that larger banks and banks operating in more concentrated local banking markets register a higher conditional probability of adopting this new technology all else equal we also find that other results are consistent with the underlying model and that the bank s regulatory environment shapes its adoption decision in plausible ways

keep searching and you ll find what do we know about variety creation through firms search activities for innovation this article critically reviews and synthesizes the contributions found in theoretical and empirical studies of firm level innovation search processes it explores the advantages and disadvantages of local and non local search discusses organizational responses and identifies potential exogenous triggers for different kinds of search it argues that the initial focus on local search was a consequence in part of the attention in evolutionary economics to path dependent behavior but that as localized behavior was increasingly accepted as the standard mode studies began to question whether local search was the best solution in all cases more recently the literature has focused on the trade offs being created by firms having to balance local and non local search we account also for the apparent variety paradox in the stylized fact that organizations within the same industry tend to follow different search strategies but end up with very similar technological profiles in fast growing technologies the article concludes by highlighting what we have learnt from the literature and suggesting some new avenues for research

the marginal cost of raising tax revenue and redistributing income we present analytic formulas for calculating marginal welfare costs when taxes are levied against the wages of a heterogeneous population of households and marginal tax revenue finances either the supply of a public good or lump sum transfers the formulas are applied to explain the wide discrepancy between estimates of marginal welfare costs for redistribution previously obtained through computer simulation procedures our calculations reveal that these procedures introduced lump sum transfers that were not specified as part of the reforms to be simulated but explain most of the differences between their estimates we also show that welfare cost estimates are quite sensitive to the elasticity of labor supply with respect to exhaustive public spending

a failure inducement model of research and development expenditure abstract empirical evidence for the schumpeterian suggestion of a positive relationship between profitability and innovative effort is slim in fact the opposite is often suggested an alternative failure inducement hypothesis argues that firms make innovative efforts when performance falls below a minimum threshold resulting in a negative relationship between profitability and r d expenditures data on r d expenditures in italian industry in the early 1980s a period of severe economic crisis show that both hypotheses are relevant for firms whose profits are well above or well below average respectively

optimal control of externalities in the presence of income taxation a substantial literature examines second best environmental policy focusing particularly on how the pigouvian directive that marginal taxes should equal marginal external harms needs to be modified in light of the preexisting distortion due to labor income taxation additional literature is motivated by the possibility that distributive concerns should amend the internalization prescription it is demonstrated however that simple first best rules unmodified for labor supply distortion or distribution are correct in a natural basic formulation of the problem specifically setting all commodity taxes equal to marginal harms and subsidies equal to marginal benefits can generate a pareto improvement likewise a marginal reform in the direction of the first best can yield a pareto improvement qualifications and explanations for differences from previous work are also presented

how to make a carbon tax reform progressive the role of subsistence consumption this letter analyzes the distributional effects of a carbon tax reform when households must consume carbon intensive goods above a subsistence level the reform is progressive if revenues are recycled as uniform lump sum transfers in other cases it is regressive

output and attribute based carbon regulation under uncertainty abstract output based carbon regulations such as fuel economy standards and the rate based standards in the clean power plan create well known incentives to inefficiently increase output similar distortions are created by attribute based regulations this paper demonstrates that despite these distortions output and attribute based standards can always yield strictly greater expected welfare than flat emission standards given uncertainty in demand for output or attributes assuming locally constant marginal damages for fuel economy standards the welfare maximizing amount of attribute or mileage basing is likely small relative to current policy for the electricity sector however an intensity standard may yield greater expected welfare than a flat standard

externalities and optimal taxation this paper reexamines the optimal tax design problem income and commodities in the presence of externalities the nature of the second best and the choice of the tax instruments are motivated by the informational structure in the economy the main results are i environmental levies linear or nonlinear differ in formula from pigouvian taxes by the expressions for the optimal tax on private goods ii externalities do not affect commodity tax formulas linear and nonlinear for private goods iii externalities do not affect the income tax structure if commodity taxes are nonlinear and affect it if commodity taxes are linear and iv a general income tax plus strictly pigouvian taxes are sufficient for efficient taxation if individuals of different types have identical marginal rates of substitution at any given consumption bundle

direct versus indirect taxation the design of the tax structure revisited this article studies the optimal direct indirect tax mix problem when individuals differ in several unobservable characteristics productivity and endowments it presents general expressions for the optimal commodity tax rates and proves that contrary to atkinson and stiglitz s 1976 result differential commodity taxation remains a useful instrument of tax policy even if preferences are separable between labor and produced goods when cross substitution effects are zero the expressions resemble traditional many households ramsey rules in a cobb douglas illustration where endowments differ only in good 1 interpreted as wealth the tax on good 2 provides an indirect way to tax the unobservable wealth

on the competitive pressure created by the diffusion of innovations abstract we consider the decision of a dominant firm to adopt a sequence of potential cost reducing innovations where the latest technology adopted diffuses to a competitive fringe at an exogenous rate with price competition on the product market the leader optimally spaces apart the adoption dates of successive innovations so the industry is characterized by schumpetarian cycles of alternating innovation and diffusion an increase in the rate of diffusion has ambiguous effects on innovative activity and up to a point hastens the pace of innovation these results may however be reversed in the case of quantity competition

the desirability of commodity taxation under non linear income taxation and heterogeneous tastes abstract this paper revisits the atkinson stiglitz result on uselessness of commodity taxation in the presence of optimal non linear income taxation in a more general setup namely when tastes are heterogeneous this general analysis displays the key economic assumptions under which the atkinson stiglitz result is robust a small tax on a given commodity is desirable if high income earners have a relatively higher taste for this commodity or if consumption of this commodity increases with leisure an application to the case of savings suggests that even in the presence of optimal non linear earnings taxation there is a role for a supplemental capital income tax in the standard overlapping generation model

the role of potential competition in industrial organization potential competition has been recognized as a mechanism to control the exploitation of market power at least since the work of j b clark 1902 but it was not until 50 years later that economists most notably joe bain and paolo sylos labini refocused attention on the idea with inputs from the theories of imperfect competition optimal control and dynamic games their work evolved into ever more sophisticated models of the reactions of existing competitors to the threat of new competition although the most appropriate models of competitive interaction are those which begin with a specific industry a number of theories have been proposed which attempt to develop more general conclusions my purpose in this paper is to develop an understanding of the strengths and limitations of these alternative theories by examining the available theoretical empirical and institutional knowledge rather than attempt the sisyphean task of recounting every model which relates conditions of entry and market performance i have partitioned the analysis into four major schools of thought according to their most central propositions these are the traditional model of limit pricing dynamic limit pricing the theory of contestable markets and the market efficiency model traditional limit pricing models rest on the assumption that firms respond to entry but are able to earn persistent profits when the structural characteristics of markets make entry difficult dynamic limit pricing is similar but emphasizes that markets can only be temporarily protected from entry contestability theory in its pure form asserts that potential competition is as effective as actual competition in controlling market performance the efficient markets hypothesis broadly interpreted states that markets are workably competitive and that the market structure reflects differential efficiency not strategic behavior while one can construct many other hypotheses about potential competition these classifications

should the good and the selfish be taxed differently in this paper we consider an environment where individual actions have externalities and two types of agents exist agents with social preferences the good and selfish agents selfish agents have pay off functions that do not take into account social welfare the pay off of an agent is a linear combination of social welfare and the pay off of a selfish agent we demonstrate that the corrective tax rates that maximize social welfare do not depend on the degree of social preferences hence the good and the selfish should not be taxed differently

using cost observation to regulate firms the paper emphasizes the use of accounting data in regulatory or procurement contracts when the supplier 1 has superior information about the cost of the project and 2 invests in cost reduction the main result states that under risk neutrality the supplier announces an expected cost and is given an incentive contract linear in cost overruns this optimal contract moves toward a fixed price contract as the announced cost decreases an investment choice is then introduced and the use of a rate of return regulation is studied

optimal dynamic carbon taxes in a climate economy model with distortionary fiscal policy how should carbon be taxed as a part of fiscal policy the literature on optimal carbon pricing often abstracts from other taxes however when governments raise revenues with distortionary taxes carbon levies have fiscal impacts while they raise revenues directly they may shrink the bases of other taxes e g by decreasing employment this article theoretically characterizes and then quantifies optimal carbon taxes in a dynamic general equilibrium climate economy model with distortionary fiscal policy first this article establishes a novel theoretical relationship between the optimal taxation of carbon and of capital income this link arises because carbon emissions destroy natural capital they accumulate in the atmosphere and decrease future output consequently this article shows how the standard logic against capital income taxes extends to distortions on environmental capital investments second this article characterizes optimal climate policy in sub optimal fiscal settings where income taxes are constrained to remain at their observed levels third this article presents a detailed calibration that builds on the seminal dice approach but adds features essential for a setting with distortionary taxes such as a differentiation between climate change production impacts e g on agriculture and direct utility impacts e g on biodiversity existence value the central quantitative finding is that optimal carbon tax schedules are 8 24 lower when there are distortionary taxes compared to the setting with lump sum taxes considered in the literature

technological change and the boundaries of the firm the authors examine a firm s decision either to produce an essential input itself or to hire a subcontractor to produce the input the authors focus on how this decision is affected by technological change in the industry in general cost reducing technological change leads the firm to produce the input itself more often the firm s calculus is shown to depend on whether the subcontractor s skills are idiosyncratic or transferable in the latter case technological progress can even be detrimental to the firm and to society as a whole copyright 1991 by american economic association

on the ir relevance of distribution and labor supply distortion to government policy should the assessment of government policies such as the provision of public goods and the control of externalities deviate from first best principles to account for distributive effects and the distortionary cost of labor income taxation for example is the optimal extent of public goods provision smaller than indicated by the samuelson rule because finance is distortionary or should environmental regulations fail to internalize externalities fully if the incidence of the regulations is regressive it is suggested that these questions are best addressed by considering distribution neutral implementation in which budget balance is achieved by choosing an adjustment to the income tax that offsets the distributive impact of the policy in question in basic cases both distribution and labor supply distortion are moot because the target policy and the tax adjustment produce offsetting effects on each thus traditional first best principles provide good benchmarks for policy analysis after all moreover even when actual implementation will not be distribution neutral in aggregate distribution neutral policy analysis has many conceptual and practical virtues that render it quite useful to investigators

innovation and technical change abstract in previous work it was established that the u k tractor industry was characterised by a high degree of technical change and that this was brought about by a process of more or less continuous incremental innovation what was lacking was an analysis of how much technical change had been introduced and an indication of the role played by technical change in determining the performance of the u k tractor industry internationally this paper concludes that on the average technical change in the industry had increased by as much as 150 percent during the years 1959 1977 though there is some indication that the rate of change might now be slowing somewhat in order to determine the relative importance of technical change a method was developed to operationalise the distinction between price and non price competition as well as the idea of intrinsic technical and associative non technical factors as constituents of the latter based on cross sectional data for the year 1978 it has been possible to show that british manufacturers tend to produce moderately priced tractors of low to medium technical sophistication that german manufacturers produced the most technically sophisticated tractors that the italian manufacturers are not generally more sophisticated technically than the british producers except with respect to their development of four wheel drive and that comecon based producers combine a very low price with some degree of technical sophistication finally it has been possible to show that the tractors with the highest sales are among the less sophisticated in each of the power ranges investigated and that new entrants used technical sophistication as an element of their entry strategy the answer to the question of what allows the market leader to be market leader required the development of measures for associative non price factors such as the availability of a dealer network brand loyalty resale prices of tractor models etc by performing a regression analysis on these measures along with previously derived measures of quality adjusted price and relative technical sophistication it has been possible to show that market leadership is achieved as a result of a balance of a number of factors the most important of which are the size of the dealer network warrants cost advertising technical sophistication and price

the diffusion of new technology and the market for an innovation this article shows that the diffusion of a capital embodied process innovation results from a pattern of decreasing incremental benefits and adoption costs for later adoptions strategic behavior is inessential to this finding we develop a method for comparing diffusion rates for different market structures in the capital equipment market we consider cases with market power on the seller s side of the market and on the buyers side of the market a case with no market power and the welfare optimal case we find that a joint venture adopts an innovation more slowly than other market regimes to protect existing capital investments and that the adoption rate is slower than is socially optimal a monopoly supplier on the other hand adopts at a rate faster than is socially optimal this result is usually also the case when there is no market power finally we show that the monopoly supplier accelerates adoptions faster than in the case where there is no market power but retards later adoptions market power thus makes a difference in diffusion rates and on which side of the market that power lies makes a considerable difference

minimum wage policy with optimal taxes and unemployment abstract using a search model i derive a formula that links the welfare gains from the minimum wage to its effect on low skilled labor force participation and employment this formula shows that the minimum wage is welfare improving if pushing the low skilled labor market tightness downwards brings it closer to its efficient level i estimate the causal effect of the minimum wage on low skilled labor force participation and employment using federal and state minimum wage variation i discuss the policy implications of my estimates when viewed through the lens of the marginal welfare gain formula

sluggish giants sticky cultures and dynamic capability transformation abstract using a theoretical framework derived from contemporary literature this paper investigates whether large and culturally dominant firms can transform their capabilities over time strategic capabilities as articulated in theory include resource accumulation and resource configuration to these is added the capability of resource utilization which comes about because of tacit and inimitable intra firm coordination skills and is a key performance measurement metric this article evaluates whether large firms in the u s telecommunications industry have been able to effect a transformation in their strategic performance over a 16 year period of time 1975 to 1990 since the late 1960s and early 1970s many measures have been undertaken to restructure the industry environment and these culminated in the 1984 divestiture by at t of this 22 bell operating companies bocs to seven regional holding companies rhcs simultaneously a series of steps opened competition in many markets for not only the rhcs but for the other local operating companies of which there are approximately 25 large ones which in many cases are bigger than some of the companies belonging to the rhc fold the local operating companies have faced a major transformation in their environment in the last 10 years once protected monopolies they now face increasing competition in many market segments which were once their profit sanctuaries enabling them to cross subsidize many unprofitable operations for the larger operating companies once owned by at t there was the shock of divestiture and re birth providing them an opportunity to engage in entrepreneurially oriented behavior thus the u s telecommunications industry provides a useful laboratory within which to analyze performance and capability transformation additionally one of the key issues that the literature is concerned with is the transformation in the performance of existing organizations this article provides evidence on the key issue of corporate performance transformation for the principal firms that comprise one of the most important industries of contemporary times it is a transformation that continues at an even faster pace today the results show that in a dynamic setting size no longer materially influences negative performance inertia arguments about the ability of large firms to effect change are not validated in the context of a dynamic u s telecommunications industry with a larger variety and pool of resources available larger firms can undergo transformation through a process of dynamic learning as effectively as smaller firms the relative transformation of the erstwhile bell operating companies is a testimony to this assertion the results have some implications for downsizing received wisdom means that less is better and smaller is swifter downsizing means dispersal of assets and resources particularly human resources which embody firm specific skills and knowledge which types of resources are lost in this process is critical to the eventual success of such endeavors with downsizing the ability of large firms to transform themselves via internal learning may be lost dynamic learning implies information scale economy exploitation and to the extent that critical mass is reduced through downsizing there is lesser diffusion of information and knowledge as a qualitatively important part of this human capital mass is reduced there is less impact of future learning as firm specific knowledge which could be combined with emergent information to create new capabilities disappears in such circumstances whether large firms can transform themselves successfully is a salient issue that ought to be further evaluated

on the diffusion of new technology a game theoretic approach this paper is an attempt at a rigorous albeit not exceedingly general analysis of the diffusion of new technology in particular consider an industry composed of two firms each using the current best practice technology the firms are assumed to be operating at nash equilibrium output levels generating a market price given demand and profit allocations when a cost reducing innovation is announced each firm must determine when if ever to adopt it based in part upon the discounted cost of implementing the new technology and in part upon the behavior of the rival firm if either firm adopts before the other it can expect to make substantial profits at the expense of the other firm on the other hand the discounted sum of purchase price and adjustment costs may decline with the lengthening of the adjustment period as various quasi fixed factors become more easily variable therefore although waiting costs the firm more in terms of foregone profits it may save money on the cost of purchasing the new technology thus the firm must weigh the costs and benefits of delaying adoption as well as take account of its rival s strategic behavior

a branch of economics is missing micro micro theory jn the life history of most sciences there are movements toward the study of larger aggregates or toward the detailed study of smaller and more fundamental units my impression is that in most fields the movement toward the study of more micro units has predominated yet in economics in the 1930 s the movement was in the macro direction both physics and biology in the last three decades have made great strides by studying smaller and smaller entitiesphysics by studying more minute fundamental particles and biology by studying the fundamental elements determining genetics in a general sense economics has not been moving in this direction although some work of this nature exists the purpose of this paper is to review some samples of the work that exists and to argue that this area must become a major field of economic research and study the question of how individuals in multiperson firms influence firm decisions seems like such a natural question to ask that it is amazing that it is not part of the formal agenda of economists as a profession of course it has been asked but not by present day economists in their professional capacity in other words micromicroeconomics has never become an established field for the most part theorists have not only not raised this question but they have continued to develop micro theory in such a way as to discourage economists from raising this question part of the reason for this lies in the maximizing and optimizing biases of conventional micro theory and part can be ascribed to the consequences of the long period required to refine the theory so that elements that did not fit the basic model were discarded

when environmental and redistribution concerns collide the case of electricity pricing abstract countries worldwide face major income inequality and environmental challenges however recent social upheavals reveal the conflict of interests induced by policies designed to address these concerns one example relates to residential electricity where volumetric grid charges and taxes may impede the affordability of electricity we develop and calibrate a model that captures the social planner s trade off between inequality aversion and environmental concerns we employ panel data on 105 000 households in the swiss canton of bern from 2008 to 2013 including electricity consumption household income and tax payment characteristics the results show that with inequity aversion and no negative environmental externalities electricity consumption should be subsidised by income tax revenue with negative environmental externalities or asymmetric information between the government and the utility end user electricity prices are shifted upwards for high degrees of inequality aversion the optimal electricity end user price is below the marginal cost even in the presence of negative environmental externalities

preemption and rent equalization in the adoption of new technology we study the adoption of a new technology to illustrate the effects of preemption in games of timing we show that the threat of preemption equalizes rents in a duopoly but that this result does not extend to the general oligopoly game if the gain to preemption is sufficiently small then the optimal symmetric outcome which involves late adoption is an equilibrium this contrasts with reinganum s result that in precommitment equilibria there must be diffusion we develop a new and richer formalism for modeling games of timing which permits a continuoustime representation of the limit of discrete time mixed strategy equilibria

redistribution and pollution taxes with non linear engel curves abstract this paper analyses optimal corrective taxation and optimal income redistribution the pigouvian pollution tax is higher if pollution damages disproportionally hurt the poor due to equity weighting of pollution damages moreover under general utility functions optimal pollution taxes should be set below the pigouvian tax if the poor spend a disproportionate fraction of their income on polluting goods however if engel curves are linear optimal pollution taxes should follow the first best rule for the pigouvian corrective tax even if the government wants to redistribute income and the poor spend a disproportional part of their income on polluting goods the often used quasi linear ces and stone geary utility functions all have linear engel curves if engel curves are linear and if pollution taxes are not optimised pareto improving green tax reforms exist that move the pollution tax closer to the pigouvian tax simulations demonstrate that optimal corrective taxes should be pigouvian if the demand for polluting goods is derived from a les demand system but deviate from the pigouvian taxes if demand for polluting goods demand is derived from a piglog demand system

incentives for conservation and quality improvement by public utilities the author examines the design of incentive programs to motivate regulated utilities to supply both basic service e g electricity supply local telephone service and service enhancements e g energy conservation services improved clarity and speed of voice communication the optimal regulatory programs are shown to vary greatly depending upon the information available to the regulator the price of the basic service may optimally be distorted above or below marginal cost to better motivate the supply of the service enhancement policy prescriptions are compared with current programs and proposals to promote energy conservation 35 refs 2 figs

distributional effects of alternative vehicle pollution control policies abstract previous work shows that policies that subsidize new vehicles and tax size miles or gasoline efficiently reduce pollution less is known about their distributional effects this paper examines distributional effects by estimating the joint demand for vehicles and miles using the consumer expenditure survey greater price responsiveness among low income households enhances progressivity of gas or miles taxes across lower incomes and mitigates regressivity across upper incomes taxes on engine size or subsidies to new vehicles are significantly more regressive than gas or miles taxes

the marginal efficiency effects of taxes and subsidies in the presence of externalities a computational general equilibrium approach abstract using 1983 data we develop a 19 sector computational general equilibrium model incorporating producer producer externalities and producer consumer externalities simulation results indicate that when additional government expenditure is financed by pigouvian taxes the marginal cost of public funds is substantially below one labor sales and output taxes also affect the output of the polluting industries and thus have indirect pigouvian effects which tend to reduce the associated marginal costs of public funds pigouvian taxes are usually more efficient than pigouvian subsidies since the tax revenue can be used to reduce other taxes

taxing externalities under financing constraints we consider an economy where production generates externalities which can be reduced by additional firm level expenditures this requires firms to raise outside financing leading to deadweight loss due to a standard agency problem vis a vis outside investors policy is constrained as firms are privately informed about their marginal cost of avoiding externalities we first derive the optimal linear pollution tax which is strictly lower than the pigouvian tax for two reasons first higher firm outside financing creates additional deadweight loss second through redistributing resources in the economy a higher tax reduces average productive efficiency we analyze various instruments that achieve a more efficient allocation in particular nonlinear pollution taxes which can no longer be implemented through a tradable permit scheme alone and grants tied to loans which are frequently observed in practice
