sustainability impacts of car road pricing a computable general equilibrium analysis for austria abstract nationwide car road pricing schemes are discussed across europe we analyse the impacts of such schemes with respect to environmental economic and social indicators of sustainability also quantifying the trade offs among these three dimensions under different charging principles and revenue recycling options in our analysis we employ a computable general equilibrium cge approach develop a modelling structure for private transport and provide detailed empirical analysis for the case of austria regarding the social dimension it has often been argued that poorer households and commuters would have to bear a disproportionate share of the road pricing burden we find the contrary i e a stronger negative policy impact on richer households and on a small group of intensive car users the choice of revenue recycling is able to ameliorate the negative social and economic effects of road pricing without reversing the desired positive environmental effects for political feasibility questions of distributional impacts are most urgent and therefore we address them systematically within a quantitative framework

road transport externalities during the last decade much progress has been made in defining measuring the external costs of transport as the cost of tolling equipment falls the set of realistic policy options to internalise these externalities will continue to grow this will determine the research and policy agenda we make three points firstly empirical work is still necessary to better identify marginal external costs including congestion accident and environmental costs secondly any assessment of policy options should treat externalities simultaneously the use of pricing instruments and emissions standards are discussed within this framework thirdly we emphasise the role of government designing the optimal road pricing institutions requires consideration of horizontal and vertical tax competition while double dividend arguments are central to the question of securing public support

welfare analysis of tax reforms using household data abstract this paper discusses a methodology for calculating the distribution of gains and losses from a policy change using data for a large sample of households estimates are based on the equivalent income function which is money metric utility defined over observable variables this enables calculations to be standardised and a computer program to compute the statistics presented in the paper is available for a general demand system equivalent income is related to measures of deadweight loss and standard errors are computed for each of the welfare measures an application to u k data for 5 895 households is given which simulates a reform that involves eliminating housing subsidies

entry barriers exit and sunk costs an analysis the relationship between entry rates entry barriers and sunk costs are examined across a set of four digit industry data results indicate that product differentiation barriers reduce entry rates and sunk capital costs reduce exit rates whether entry and exit are truly simultaneous however is not clear

second best policies for congestion externalities abstract this is the third in a series of three articles on the topic of congestion externalities we use an urban general equilibrium model to test the efficiency of several second best policies for congestion externalities the most efficient second best policy is a program of land use controls the program generates a welfare gain of 3 38 per household per week a unit tax on commuting is a less efficient policy with a welfare gain of 1 15

a political economy model of road pricing abstract in this paper we use a simple majority voting model to study the introduction of urban congestion tolls the model allows for different types of uncertainty and considers different uses of the toll revenues the following results are obtained first we show that individual uncertainty with respect to modal substitution costs may imply that a majority votes against road pricing ex ante although a majority would have been in favor after its introduction ex post moreover if a majority is against road pricing ex ante there will also be no majority for organizing an experiment that would take away the individual uncertainty second political uncertainty with respect to the use of the revenues corroborates the finding that ex ante more voters will be against the introduction of tolls third both types of uncertainty suggest that fewer voters are against road pricing when toll revenues are used to subsidize public transport than when they are redistributed to all voters importantly the results of this paper are consistent with a number of recent empirical observations on efforts to introduce road pricing including the systematic rejection of road pricing in referenda the more favorable attitudes towards road pricing after than before its introduction and tying the toll revenues to support public transport

conceptual developments in the economics of transportation an interpretive survey the objective in this paper is to survey the literature in transportation economics exploring two basic themes first the conceptual developments in the analysis of supply and demand which recognizes noteworthy aggregation biases in the empirical work on aggregate data and indicate that a correct analysis of the issues should take place at a highly disaggregated level second the use of these conceptual developments to evaluate efficiency aspects of transportation pricing investment and the impact of government regulation on resource allocation and distribution in the transportation sector it is important to acknowledge that the survey is based on research throughout the world but our institutional perspective and to some extent the topics that are covered is based largely on the u s experience author

linear inequality methods to enforce partnerships under uncertainty an overview we review different generic conditions on stochastic outcome functions to enforce either efficient or nearly efficient partnerships their logical relationship is explored two kinds of conditions are considered however the property for an action profile to be compatible plays a crucial role in both kinds also two kinds of enforcement mechanisms are considered enforcement through utility transfers and enforcement through repetition

peak load pricing of a transportation route with an unpriced substitute abstract this paper considers two routes to work which could be two bridges a freeway and a tollroad or roadway travel and subway travel both routes are subject to pure bottleneck and queue congestion if peak load pricing can be imposed on both routes the first best solution is attained however if one route is unpriced then the other route should have a second best time varying toll that is negative at the tails of the rush hour positive near the peak of the rush hour and zero on average if the two routes have the same capacities and if the parameter g is 1 then two thirds of the total traffic should use the priced route and the efficiency gain of second best pricing is two thirds of the efficiency gain of first best pricing

buying greenhouse insurance the economic costs of carbon dioxide emission limits in recent years a growing concern that the increasing accumulation of greenhouse gases will lead to undesirable changes in global climate has resulted in a number of proposals both in the united states and internationally to set physical targets for reducing greenhouse gas emissions but what will these proposals cost based on the authors earlier ground breaking work buying greenhouse insurance outlines a way to think about greenhouse effect decisions under uncertainty it describes an insightful model for determining the economic costs of limiting carbon dioxide emissions produced by burning fossil fuels and provides a solid analytical base for rethinking public policy on the farreaching issue of global warming manne and richels present region by region estimates of the costs that would underlie an international agreement using a computer model known as global 2100 they analyze the economic impacts of limiting c02 emissions under alternative supply and conservation scenarios the results clearly indicate that a reduction in emissions is not the sole policy response to potential climate change following a summary of the greenhouse effect its likely causes and possible consequences manne and richels take up issues that concern the public at large they provide an overview of global 2100 look at how the u s energy sector is likely to evolve under businessas usual conditions and under carbon constraints and describe the concept of greenhouse insurance they consider possible global agreements including an estimate of benefits that might result from trading in an international market in emission rights they conclude with a technical description directed toward modeling specialists alan manne is professor of operations research at stanford university richard richels is director of the energy analysis and planning department at the electric power research institute

why truck distance taxes are contagious and drive fuel taxes to the bottom this paper analyzes the way in which countries with international and local truck traffic decide to switch from a simple fuel tax system to a dual system of fuel and distance charge taxes we show what drives a country to switch and how this affects the level of fuel taxes as well as incentives for other countries to also adopt the dual system the model is partially able to explain the gradual extension of kilometer charging for trucks in europe the model also shows that in the absence of diesel cars the gradual introduction of kilometer charges will make fuel taxation for trucks virtually disappear and will lead to a system where truck use is 1 taxed mainly based on distance 2 is taxed too heavily and 3 where highest distance taxes are expected in transit countries with a strong market position when the fuel tax must in addition serve as an externality tax for diesel cars the introduction of distance charges for trucks will give rise to diesel taxes that are lower than the external cost of diesel cars for trucks this leads to a sum of diesel taxes and distance charges that are higher than the external cost of trucks

a pigovian rule for the optimum provision of public goods abstract the integrated treatment of optimal taxation and public expenditure presented here is based on the dual relationship between the prices of private goods and the quantities of public goods the conditions for optimum public good provision can be expressed as a modification of the samuelson conditions with extra terms representing a the distortionary effect of taxes on the willingness to pay for the public good and b distributional effects the former captures pigou s notion of the indirect damage caused by the need to finance public expenditure out of distortionary taxes and we call this the pigou term in certain cases a very simple benefit cost ratio for public projects emerges that is equivalent to measuring benefits as if they were taxed

funding transportation spending in metropolitan washington dc the costs of alternative revenue sources abstract this paper develops and implements an analytical framework for estimating the efficiency costs of raising additional revenue from taxes on labor property gasoline peak road use and higher transit fares for the washington dc area the model incorporates driving externalities and interactions between the different policies an economic case can be made for using congestion taxes and possibly gasoline and property taxes to raise extra revenue though it should be qualified for example the inelastic demand for driving limits the congestion benefits per dollar of revenue raised and these taxes have adverse employment effects in the same way that a tax on labor income does

investigating geography and institutions as determinants of foreign direct investment in africa using panel data this article uses a cross country econometric approach to identify the determinants for foreign direct investment fdi in africa the contribution is 3 fold firstly we recognize that the estimation techniques used elsewhere such as ordinary least squares may be flawed we therefore use a dynamic one step generalized method of moments gmm estimator due to arellano and bond 1991 the gmm estimates identified a number of robust determinants of fdi namely government consumption inflation rate investment governance political stability accountability regulatory burden rule of law and initial literacy it is concluded that geography does not seem to have a direct influence on fdi flows to africa neither market seeking nor re exporting motives of fdi seem to dominate with different policy instruments being significant in the different specifications this does not discount the importance of good policies but probably indicates the importance of good policies made by good institutions institu

general equilibrium concepts under imperfect competition a cournotian approach in a pure exchange economy we propose a general equilibrium concept under imperfect competition the cournotian monopolistic competition equilibrium and compare it to the cournot walras and the monopolistic competition concepts the advantage of the proposed concept is to require less computational ability from the agents the comparison is made first through a simple example then through a mon abstract concept the p equilibrium based on a general notion of price coordination c 1997 academic press

the london congestion charge by the 1990s the average speed of trips across london was below that at the beginning of the twentieth century before the car was introduced and by the end of that decade public concern over levels of traffic congestion was high in early 2003 london imposed a congestion charge a daily charge for driving or parking a vehicle on public roads within central london between the hours of 7 00 a m and 6 30 p m on workdays traffic congestion has declined substantially and the program is largely popular this article describes the origins of the london congestion charge how it overcame practical and theoretical difficulties and what effects it has had the introduction of the london congestion charge is in important respects a triumph of economics it represents a high profile public and political recognition of congestion as a distorting externality and of road pricing as an appropriate policy response

congestion tolling with agglomeration externalities abstract consider an urban economy with two types of externalities negative traffic congestion externalities and positive agglomeration externalities deriving from non market interaction suppose that urban travel can be tolled that non market interaction cannot be subsidized and that non market interaction is stimulated by a reduction in travel costs then the optimal toll is below the congestion externality cost this paper explores this line of reasoning

transport taxes with multiple trip purposes a congestible urban transport system is considered in which cars and buses are used for commuting and non commuting trips commuting is a strict complement to taxable labour supply the optimal tax structure for raising a given amount of government revenue is examined for the cases where differentiation of transport tolls between trip purposes is and is not possible an application to belgian urban environments shows that optimal toll differentiation produces significant efficiency improvements without differentiation reforming transport taxes generates substantial gains only when the labour tax can be reduced

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

reevaluating the first and the second dividends of environmental tax reforms abstract there is increasing global interest in market based climate change policies following the last elections in the united states in this context an exxon mobil chief executive came out in favour of a carbon tax this paper is concerned with the welfare analysis of environmental tax reforms etr and takes up the claims for the need of an unambiguous and operative definition of the double dividend both for empirical purposes and political advisement in this paper we contest the usual definition of the second dividend and its assimilation to an efficiency dividend we propose alternative definitions by suggesting a different splitting of the total welfare variation between the first and the second dividend in order to isolate the efficiency effects of the etr the new definitions become clearly understandable and easy for economic and policy interpretation concepts like weak and strong double dividend turn out to be unnecessary finally we analyze etr for the us economy to illustrate the advantages of the proposed definitions for policy implementation

international trade and investments in a vertically differentiated industry abstract a model of vertical product differentiation is applied to the study of trade and investments between two economies of differing sizes at the autarky equilibrium firms in the smaller country are shown to produce lower quality the choice of the firms between exports and foreign investments when borders open is studied intra industry trade or reciprocal investments arise when the quality gap is not too wide the strategic role of foreign investments is emphasized in particular the establishment of a subsidiary abroad can crowd out both sales by local firms and exports by the co national firm

marginal tax reform externalities and income distribution the paper examines welfare improving and revenue neutral directions marginal policy reforms for an economy with nonidentical individuals and an externality that has a feedback effect on the consumption of taxed goods it considers three types of policy instruments the indirect taxes the uniform poll transfer and public abatement this extends the framework set up by ahmad and stern 1984 bovenberg and de mooij 1994 and schob 1996 the theoretical model is illustrated for a specific externality namely congestion caused by peak car transport

environmental policy public finance and the labour market in a second best world abstract environmental and tax policies and the optimal provision of clean and dirty public goods are analysed within the context of a second best framework of optimal taxation households consume both clean and dirty commodities degradation of the natural environment occurs due to the consumption of dirty private and public goods but can be offset when the government engages in abatement activities increased environmental concern implies a higher dirt tax a lower tax on labour less employment more public abatement and a cleaner environment if the elasticity of substitution between private consumption commodities and leisure is large and that between clean and dirty goods is small public consumption may expand while private consumption contracts otherwise public consumption falls

effects of carbon taxes in an economy with prior tax distortions an intertemporal general equilibrium analysis abstract this paper analyzes the costs of carbon taxes in a model that recognizes interactions between this tax and pre existing taxes first we examine the extent to which costs of a u s carbon tax are reduced when its revenues finance cuts in income taxes such use of revenues significantly reduces but does not eliminate the overall policy costs the positive overall costs reflect the carbon tax s focus on intermediate inputs and its relatively narrow base in comparison with income taxes we also examine the sensitivity of the carbon tax s costs to the level of pre existing taxes for any given use of revenues welfare costs rise significantly with pre existing tax rates indicating that models disregarding pre existing taxes may substantially understate the costs of new environmental tax initiatives

optimal taxation of car ownership car use and public transport insights derived from a discrete choice numerical optimization model in this paper we study the taxation of car ownership car use and public transport in the presence of externalities within the framework of a discrete continuous choice model we first derive optimal taxes in a simplified setting emphasizing the specific role of fixed car ownership taxes and the relevance of public transport demand by non car owners for the optimal tax structure a numerical optimisation model is then constructed to study welfareoptimal public transport fares and two part tariffs on ownership and use of gasoline and diesel cars in belgium results are as follows first we find that the current differences in tax treatment between diesel and gasoline car ownership and use cannot be justified on the basis of external cost and budgetary considerations efficient pricing requires substantial increases in the relative user tax on diesel cars as compared to gasoline cars optimal fixed taxes are substantially below current levels and only marginally differ between car fuel types second if for political or technical reasons variable car taxes cannot be optimally adjusted large differences in fixed car taxes do result the same holds if the government uses kilometre taxes as the main variable tax instrument third the results of a series of marginal tax reform exercises suggest that a shift form gasoline towards diesel taxation is welfare improving both for fixed and variable taxes somewhat surprisingly a shift from fixed towards variable taxes is not necessarily welfare improving it is for diesel but not for gasoline cars

optimal cordon pricing abstract this paper presents a simple spatial model of traffic congestion for a monocentric city to investigate the effects of cordon pricing on trip making and congestion level in each location optimal cordon pricing is obtained as a combination of the cordon location i e distance of the cordon from the cbd and the amount of toll charged there that maximizes the total social surplus in a city under optimal cordon pricing trips originating from locations inside the cordon are under priced those just outside the cordon are over priced and those near the urban fringe are under priced numerical simulations using the parameter values based on japanese data suggest that cordon pricing attains an economic welfare level very close to the first best optimum

oligopolistic competition as a common agency game oligopolistic competition is analyzed in a complete information multi principal common agency framework where principals are firms supplying differentiated goods and the agent is a representative consumer we first propose a canonical formulation of common agency games and a parameterization of the set of equilibria based on the lagrange multipliers associated with the participation and the incentive compatibility constraints of each principal this is used to characterize the set of equilibria in the intrinsic and non intrinsic games the former includes the latter as well as the standard price and quantity equilibrium outcomes it may also include the collusive solution

environmental taxes with heterogeneous consumers an application to energy consumption in france abstract this paper constructs a model with four groups of households who have preferences over labor supply consumption of polluting energy related and non polluting non energy goods and emissions it quantifies the model for the french economy and computes its optimal tax equilibria under nine second best tax regimes we find that the redistributive role of environmental taxes requires the polluting goods to be taxed at a rate much below their marginal social damage these goods may even require an outright subsidy if the society values equality a lot secondly if environmental taxes that have an exclusively externality correcting role they benefit all types although the gains are rather modest the gains and losses become more substantial when environmental taxes have a redistributive role as well third setting the environmental tax at its pigouvian level rather than its optimal externality correcting cum redistributive level benefits the high income group at the expense of the low income groups fourth nonlinear taxation of polluting goods and nonlinear commodity taxation in general is a powerful redistributive mechanism fifth introducing environmental taxes in the current french tax system with its suboptimal income taxes results in substantial welfare gains for the highest income group and a sizable loss for the least well off persons

efficient congestion tolls in the presence of unpriced congestion a peak and off peak simulation model abstract this paper develops a congestion pricing model to examine efficient congestion tolls for an urban highway facility that resembles california state route 91 the highway that has been subject to congestion tolls since december 27 1995 two lanes out of six each way are subject to congestion tolls and the other four lanes are not the simulation model combines the economic theories of second best pricing of transportation facilities and peak load pricing and considers both welfare maximizing and profit maximizing cases the simulation results show that the second best peak period toll is quite low and that the welfare gains from the toll are modest compared to a regime in which all lanes are subject to tolls

cooperative r d and vertical product differentiation abstract a partial equilibrium model with vertical product differentiation coumot competition and quality determined by r d expenses is analysed cooperative agreements on r d entail higher levels of r d quality output and welfare than at the non cooperative equilibrium under well denned conditions on spillover rates this confirms in a new setting a well known outcome of models with cost reducing r d further cooperation in r d allows a larger number of firms to operate in the industry than in the non cooperative case via a reduction in prices a new source of social gains from cooperative research is identified

regulation of road accident externalities when insurance companies have market power abstract accident externalities that individual drivers impose on one another via their presence on the road are among the most important external costs of road transport we study the regulation of these externalities when insurance companies have market power some of the results we derive have close resemblance to the earlier literature on externality regulation with market power in aviation and private roads but there are important differences too using analytical models we compare the first best public welfare maximizing outcome with a private profit maximizing monopoly and oligopoly we find that insurance companies will internalize some of the externalities depending on their degree of market power we derive optimal insurance premiums and regular parametric taxes as well as manipulable ones that make the companies set socially optimal premiums the latter take into account that the firm tries to exploit knowledge of the tax rule applied by the government finally we also study the taxation of road users rather than that of firms

state characteristics and the location of foreign direct investment within the united states a conditional logit model of the location decision of foreign firms investing in manufacturing facilities in the united states is developed and estimated the authors results for 1981 83 indicate that states with higher per capita incomes and higher densities of manufacturing activity attracted relatively more foreign direct investment in addition higher wages deterred foreign direct investment while higher unemployment rates attracted it surprisingly higher unionization rates were associated with increased foreign direct investment overall higher taxes deterred foreign direct investment however more extensive transportation infrastructures and larger promotional expenditures were associated with increased foreign direct investment copyright 1991 by mit press

the value of value pricing of roads second best pricing and product differentiation abstract some road pricing demonstrations use value pricing in which travelers can choose between a free but congested roadway and a priced roadway recent research has uncovered a potentially serious problem for such demonstrations second best tolls may be far lower than those typically charged and from a welfare perspective the latter may be worse than not pricing at all that research however assumes that all travelers are identical and it therefore neglects the benefits of product differentiation using a model with two user groups we find that accounting for heterogeneity in value of time is important in evaluating constrained policies and improves the relative performance of policies that offer differential prices

road pricing with optimal mass transit abstract this paper considers the second best policy problem that arises when auto travel is priced below its marginal cost and there is a substitute mass transit mode using analytical methods a global comparison is made between the second best levels of transit service and the fare and their first best levels the fact that the results are global permits an application to road pricing not possible with the local results of kraus 2003

the drawbacks and opportunities of carbon charges in metropolitan areas a spatial general equilibrium approach in cities there is a variety of economic and spatial forces that may influence to what extent a travel related co2 emission pricing can be an effective instrument to contribute to the achievement of co2 reduction goals therefore we examine the effectiveness and impact of co2 emission charges using a spatial general equilibrium model of an urban economy calibrated according to an average german city our analyses suggest that the imposition of a pigouvian type co2 emission charge on urban passenger travel may be able to reduce emissions by about 1 11 depending on the estimated social damage cost of carbon dioxide such a policy increases urban welfare mainly on account of a reduction of congestion costs however pricing congestion directly not only provides higher urban welfare but also higher emission reductions pricing congestion and co2 emissions simultaneously allows to achieve a wide range of emission reduction goals if however the reduction goal is very ambitious the emission charge must be raised to higher levels then distortions in the urban markets and in spatial travel decisions lower labor supply and thus urban production income of city residents federal tax revenue income of landowners outside the city all together implying losses in welfare

spatial variation of the marginal utility of income and unequal treatment of equals in one of the most famous contributions to the new urban economics literature mirrlees 6 showed that a utilitarian planner able to control the distribution of income or endowments across households the consumption of land or housing and the distribution of population over space would treat households with identical tastes unequally in the sense that utility levels would vary among them at the planner s optimum similar results were obtained by dixit 2 who showed that even more inequality averse social welfare functions than the utilitarian one would result in unequal treatment he concluded that only the rawlsian maximin welfare function would produce the equal treatment outcome 2 this result has generated considerable attention see e g mills and mackinnon 5 because of its apparently paradoxical nature the purpose of this note is to present a new way of thinking about and making plausible the unequal treatment result 3 to develop the intuition recall that in monocentric city models where equals are treated equally that is where households have equal endowments a market equilibrium with free mobility is characterized by equal utilities for all assuming identical preferences as is well known in the absence of congestion or other market failures this market equilibrium is pareto efficient producing the maximum feasible common level of utility imagine now a mirrlees planner coming across such an equal utility equilibrium under what conditions would the planner not want to disturb the market equilibrium clearly a necessary condition for equal treatment to be utilitarian optimal is that the marginal utility of income be the same for all households in the market equilibrium otherwise freezing the allocation of resources in every other respect social

second best taxation of emissions and polluting goods abstract this paper studies the problem of the design of an integrated system of second best emission and output taxes in a model where production costs are negatively correlated with their emissions it shows that i the first best pigouvian rule of equating the marginal private benefit of emissions in production to the marginal social damage of emissions must be modified in the second best ii implementation of the modified pigouvian rule requires all firms to face the same marginal emission tax equal to the marginal social damage of emissions plus an adjustment term reflecting optimal tax objectives iii it may not be necessary to directly tax the polluting goods the latter taxes can be subsumed in the emission tax function iv output taxes must be set solely on the basis of optimal tax objectives no pigouvian adjustment is required v if emission taxes are restricted to be proportional and commodity taxes are constrained the modified pigouvian rule will no longer be optimal vi if preferences are weakly separable in emissions and other goods the pigouvian rule remains valid the marginal emission tax is pigouvian and emission and commodity tax instruments can be set separately to address different objectives a proportional emission tax corrects for externalities while commodity taxes are determined solely on the basis of optimal tax considerations

revenue recycling within transport networks abstract in this paper we analyse second best pricing and investment policy for transport networks with a revenue recycling mechanism in which the toll revenue is used for transport investments or subsidies as in london s congestion charging scheme the results of this paper demonstrate that the way toll revenue is used modifies the usual results significantly which are typically based on assuming a lump sum transfer first recycling revenue as investment increases the second best toll when the benefits from the investment exceed the costs and when demand is inelastic with respect to the toll recycling revenue as a subsidy has no such effect second partial cost benefit analysis that focuses only on the targeted transport mode would usually lead to erroneous conclusions about whether toll revenues should be used for transport investment subsidies or general tax revenues thus full cost benefit analysis which accounts for changes in consumer and producer surpluses in all transport modes is necessary

optimal two part tariffs in a model of discrete choice abstract in this paper we study welfare optimal two part tariffs in a model of discrete choice the determinants of the sign and magnitude of the fixed and variable tax are analysed in terms of the nature and degree of consumer heterogeneity the price sensitivities of participation probabilities and conditional demands and the nature of distributional concerns in the absence of distributional concerns the model generalises the corrected ramsey rule for the variable tax and it shows that in the absence of collection or fixed participation costs the fixed fee may be negative the conditions that determine the sign of the participation fee turn out to have an intuitive economic interpretation finally the implications of distributional concerns for the optimal fixed and variable taxes are analysed

private roads competition and incentives to adopt time based congestion tolling abstract this paper investigates whether time based congestion tolling is profitable for a private toll road operator when competing for traffic with another road despite the fact that congestion tolling boosts revenue by reducing congestion delay it can be unprofitable if it induces a private or public toll road rival to reduce its toll severely the size of the rival s response depends on the price elasticity of travel demand and on whether the rival also employs congestion tolling in a private duopoly adoption may be unilaterally profitable but parallel adoption unprofitable so that a prisoner s dilemma obtains

on revenue recycling and the welfare effects of second best congestion pricing in a monocentric city abstract this paper examines congestion taxes in a monocentric city with pre existing labor taxation when road toll revenue is used to finance labor tax cuts 35 of the optimal road tax in our numerical model does not reflect marginal external congestion costs but rather functions as a ramsey mirrlees tax i e an efficiency enhancing mechanism allowing for an indirect spatial differentiation of the labor tax this adds a quite different motivation to road pricing since welfare gains can be produced even in absence of congestion we find that the optimal road tax is non monotonic across space reflecting the different impacts of labor supply elasticity and marginal utility of income which both vary over space the relative efficiencies of some archetype second best pricing schemes cordon toll flat kilometer tax are high 84 and 70 respectively when road toll revenue is recycled lump sum the optimal toll lies below its pigouvian level extensions in a bimodal framework show that the optimality of using road toll revenue to subsidize public transport depends on the initial inefficiency in public transport pricing

the eclectic paradigm of international production a restatement and some possible extensions this article reviews some of the criticisms directed towards the eclectic paradigm of international production over the past decade and restates its main tenets the second part of the article considers a number of possible extensions of the paradigm and concludes by asserting that it remains a robust general framework for explaining and analysing not only the economic rationale of economic production but many organisational and impact issues in relation to mne activity as well

source country characteristics and the inflow of foreign direct investment into saudi arabia the paper examines the impact of source country characteristics on the inflow of fdi into saudi arabia using a gravity type model including economic distance and socio political variables a unique database listing all new investments involving foreign ownership is used to construct a panel of 33 countries in the period 1980 2005 to account for many country year observations with zero fdi the negative binomial regression the tobit regression and the heckman selection procedure are used the conclusions drawn from the analysis employing panel based techniques differ from the results obtained from pooled regression models also the determinants of fdi differ depending on whether foreign investment is measured in terms of investment expenditure or the number of individual foreign projects the heckman selection results reveal that there are a large number of factors affecting the decision to invest in saudi arabia compared with relatively few determinants of the actual size of investment traditional size and distance characteristics hold to a great extent but the relationship between fdi and bilateral trade is unclear and there is some evidence that the countries that export to saudi arabia do not invest there in terms of scope for possible spillovers there is mixed evidence on whether the investment comes from more technologically advanced economies but volume wise important investments originate from countries characterised by high income per capita

second best congestion pricing the case of an untolled alternative abstract this paper deals with second best one route congestion pricing in case of an untolled alternative using a two link network simulation model the effects of various demand and cost parameters on the relative efficiency of one route tolling are analyzed it is investigated whether the existence of costs of congestion charging may be a reason for one route tolling to be more overall efficient than two route tolling finally the efficiency of revenue maximizing one route and two route tolling is discussed

optimal tax and public investment rules for congestion type of externalities optimal government policy is considered in a second best framework where consumers and producers cause an externality of the congestion type and income distribution issues are taken into account the theoretical results of the optimal tax literature are adapted using the concept of the net social pigouvian tax an illustrative age model uncovers the relative importance of its components the model demonstrates that the level of the externality tax does not depend strongly on distribution concerns as reoptimization of the other taxes ensures that the income distribution objective is reached the model also allows us to study the interaction between externality taxes and public abatement

comparing the efficiency of alternative policies for reducing traffic congestion abstract this paper compares the efficiency of a single lane toll a uniform congestion tax across freeway lanes a gasoline tax and a transit fare subsidy at reducing congestion there are three conditions for an efficient outcome relating to travel across modes across peak and off peak periods and sorting out drivers with high and low time costs across faster and slower freeway lanes each policy involves some inefficiency indeed the single lane toll gasoline tax and transit subsidy forego at least two thirds of the efficiency gains under an ideal congestion tax that varies across lanes however the uniform congestion tax achieves over 90 of these gains

a note on dynamic monopoly pricing under consumption externalities we analyze dynamic monopoly pricing under consumption externalities focusing on pricing under negative externalities we also attempt to generalize models in the previous literature which encompass both negative and positive externalities by incorporating a consumer s discount factor for past sales as a parameter analyzing our model reveals oscillation as the optimal price path in the presence of negative externalities

the value of scarce water measuring the inefficiency of municipal regulations abstract rather than allowing urban water prices to reflect scarcity rents during periods of drought induced excess demand policy makers have mandated command and control approaches primarily rationing the use of water outdoors while such policies are ubiquitous and likely inefficient economists have not had access to sufficient data to estimate their economic impact using unique panel data on residential end uses of water in 11 north american cities we examine the welfare implications of urban water rationing in response to drought using estimates of expected marginal prices that vary both across and within markets we estimate price elasticities specific to indoor and outdoor water use our results suggest that current policies do target water uses that households themselves are most willing to forgo nevertheless we find that rationing outdoor water in cities has costly welfare implications primarily due to household heterogeneity in willingness to pay for scarce water we find that replacing rationing policies with a market clearing drought price would result in welfare gains of more than 29 of what households in the sample spend each year on water

when is increasing consumption of common property optimal sorting congestion and entry in the commons abstract first best pricing or assignment of property rights for rival and non excludable goods is often infeasible in a setting where the social planner cannot limit total use we show that common property resources can be over or under consumed this depends on whether the external benefits of reallocating users to less congested resources outweigh the additional costs imposed by new entrants importantly we show that it may be optimal to encourage consumption of some common property resources our results have important implications for settings ranging from fisheries and forestry to recreational demand and transportation

correcting externalities through taxes on subsidies to related goods abstract optimal corrective taxation is considered in the presence of externalities in cases where only related goods i e complements to or substitutes for externality creating goods can be taxed in the context of identical individuals and separable externalities taxing and subsidizing complements and substitutes to externalities are analyzed first the circumstances under which it is optimal to operate on one market only for a related good are examined second cases are identified where optimality requires taxes on substitutes for or subsidies to complements to a good which generates negative externalities

prices capacities and service levels in a congestible bertrand duopoly we study the duopolistic interaction between congestible facilities that supply perfect substitutes and that make sequential decisions on capacities and prices the consumers time cost of accessing or using a facility is determined by the volume capacity ratio we analyze duopoly prices capacities and service quality defined as the inverse of time costs of using the facility and compare the results to monopoly and first best outcomes findings include the following first while price competition between duopolists is beneficial for consumers introducing capacity competition is harmful the duopolist offers lower service quality than the monopolist who does provide the socially optimal quality level second higher marginal costs of capacity may increase profits third asymmetric nash equilibria may result even when firms are ex ante identical more specifically when capacity is cheap or demand is relatively inelastic the only stable equilibria are asymmetric in such an equilibrium the large facility provides high quality at a high price and the smaller facility offers lower quality at lower prices in other words there is endogenous product differentiation by ex ante identical firms

carpooling and driver responses to fuel price changes evidence from traffic flows in los angeles abstract we examine carpooling and driver responses to fuel price changes using a simple theoretical model we show that traffic flows in mainline lanes unambiguously decrease when fuel prices increase and this effect is stronger when the presence of a carpool lane provides a substitute to driving alone in contrast in carpool hov lanes flow can either increase or decrease these predictions are tested using 8 years of traffic flow data for 1700 locations in los angeles in our preferred specification the mean elasticity of flow with respect to fuel price is 0 136 for hov lanes for a 10 increase in fuel price this implies 10 additional carpools per hour 8 8 million per year in additional congestion costs for carpoolers and 11 3 million lower costs for mainline drivers for mainline lanes flow elasticities are 0 083 and 0 050 for highways with and without an hov lane these estimates imply that the mean highway with an hov lane experiences a 30 larger decrease in hourly flow compared to the mean highway without an hov lane flows in hov lanes show an immediate decrease following a price increase but respond positively to price increases over time which suggests time is an important input to carpool formation

transport tax reform commuting and endogenous values of time abstract we consider a model of urban transport with two trip purposes commuting assumed perfectly complementary to labour supply and noncommuting to analyse the effects of transport tax reform on the value of time and marginal external congestion costs higher commuting taxes plausibly reduce time values but higher noncommuting transport prices will typically raise the value of time the intuition for this latter finding is that the reduction in congestion that follows from the tax increase itself raises net wages per hour of work inclusive of commuting time empirical illustrations with belgian data show a potentially large effect of transport tax reform on time values in quite a few of the tax reforms studied traffic levels are reduced but the increase in time values implies that marginal external congestion costs actually increase

locational advantage and us foreign direct investment in uk manufacturing the relationship between foreign direct investment fdi and international trade is examined with specific reference to us fdi in the uk four complementary hypotheses are tested on a cross section of uk industries there is evidence of us fdi being located in uk industries which have a revealed comparative advantage and that large market size effects are important on the other hand little evidence was found for the protection jumping and industrial concentration hypotheses

how much does subnational region matter to foreign subsidiary performance evidence from fortune global 500 corporations investment in china what explains the heterogeneity of foreign subsidiary performance previous studies have emphasized the importance of industry corporate parent and home country effects on the variation of foreign subsidiary performance building on recent international business and economic geography research this study examines the extent to which subnational region effects can also explain such performance variation we empirically decompose the variance of the performance of fortune global 500 corporations subsidiaries in china during 1998 2006 results show that not only are subnational region effects statistically significant in explaining the variation of subsidiary performance but their interactions with industry corporate parent and home country effects are also significant and economically important we further show that subnational region effects tend to be stronger in the period prior to china s wto accession and in the country s less developed subnational regions our findings highlight the importance of considering both the direct and indirect roles of subnational region in shaping firms strategy and performance in international business research

second best pollution taxes and the structure of preferences we characterize optimal taxes on polluting and nonpolluting goods in ramsey and mirrlees second best environments the polluting good tax differs from the pigouvian tax by ramsey terms in the first and by stiglitz mirrlees plus another adjustment term in the second these terms can be positive negative or zero if preferences are weakly separable in public and private goods with the private good subutility weakly separable in labor and produced goods nonpolluting goods are taxed uniformly and the concept of a tax differential between polluting and nonpolluting goods is well defined the differential is then less than the pigouvian tax in the ramsey framework but it can be greater equal to or smaller than the pigouvian tax in the mirrlees second best in mirrlees second best if preferences are separable in labor supply and other goods the second best tax differential is identical to the pigouvian tax

revenue recycling and the welfare effects of road pricing the authors explore the interaction between taxes on work related traffic congestion and preexisting distortionary taxes in the labor market a congestion tax raises the overall costs of commuting to work and discourages labor force participation at the margin when revenues are returned in lump sum transfers the resulting efficiency loss in the labor market can be larger that the pigouvian efficiency gains from internalizing the congestion externality by contrast if congestion tax revenues are used to reduce labor taxes the net impact on the labor supply is positive and the efficiency gain in the labor market can raise the overall welfare gains of the congestion tax by as much as 100 percent recycling congestion tax revenues in public transit subsidies produces a positive but smaller impact on the labor supply in short the authors results indicate that the presence of preexisting tax distortions and the form of revenue recycling can crucially affect the size and possibly even the sign of the welfare effect of road pricing schemes the efficiency gains from recycling congestion tax revenues in other tax reductions can amount to several times the pigouvian welfare gains from congestion reduction

intra industry trade and investment under oligopoly the role of market size this paper examines the factors which influence intra industry trade under oligopoly it argues that major determinants are the size of markets and the height of trade barriers if national markets are large and trade barriers high intra industry trade is replaced by cross investment between countries whereby firms serve the markets of their foreign rivals by investing abroad instead of exporting this result is established formally using a simple two country two firm game theoretic model the same model is also used to examine how barriers to trade influence prices and output the paper concludes with a brief discussion of how economic growth affects the volume of intra industry trade copyright 1992 by royal economic society

should congestion tolls be set by the government or by the private sector the knight pigou debate revisited this paper clarifies issues debated by a c pigou and frank knight about correcting inefficient use of congestible resources focusing for concreteness on their original example of road congestion instead of government imposed pigouvian access fees knight favoured access fees set by private toll setters we consider the case of n 2 congestible roads and an uncongestible road of arbitrary speed knight argued that in the case of a single congestible road a private toll setter would always choose the toll that pigou recommended hence the allocation would minimize aggregate commute time without government meddling we find instead that two or more toll setters would never choose pigouvian tolls except in the special case of a sufficiently fast uncongestible road moreover for uncongestible roads of slower speed the allocation of motorists under knight s proposal is almost never efficient whenever it is inefficient motorists are strictly worse off when they pay tolls set by private firms instead of paying government imposed tolls and aggregate toll revenue is also lower nevertheless if the private sector does set tolls then the full cost to motorists can be limited if the government provides an uncongestible alternative such as a train to offer potential competition along the same route

second best energy policies for heterogeneous firms this paper investigates second best issues in the regulation of external costs of energy use by heterogeneous firms the efficiency of regulatory energy policies depends in general on the policy incentives given for both output reduction and input substitution the resulting endogeneity of firms supply functions appears to lead to complicated policy rules in contrast to earlier efforts the analysis considers an arbitrarily large number of non identical price taking firms in a joint market a large variety of possible production functions including varying levels of economies of scale and possibilities for input substitution and elasticities of market demand which may vary from completely elastic to completely inelastic two second best instruments are considered namely output taxes and energy efficiency standards and are compared to the benchmark of first best energy taxes the underlying market factors determining the relative efficiency of these second best instruments when used optimally are identified

competition for market share or for market size oligopolistic equilibria with varying competitive toughness for an industry producing a composite commodity we propose a comprehensive concept of oligopolistic equilibrium allowing for a parameterized continuum of regimes varying in competitive toughness each firm sets simultaneously its price and its quantity under two constraints relative to its market share and to market size the price and the quantity equilibrium outcomes always belong to the set of oligopolistic equilibria when firms are identical and we let their number increase any sequence of symmetric oligopolistic equilibria converges to the monopolistic competition outcome further results are derived in the symmetric ces case concerning in particular the collusive solution enforceability

second best road taxes in polycentric networks with distorted labor markets this paper examines the interaction of road taxes with spatially invariant labor taxation in a polycentric network it derives analytical expressions for the network counterparts of the traditional double dividend effects i e pigouvian tax interaction and revenue recycling effects and computes them under different policy regimes the analysis reveals a series of conditions under which a system of cordons around the major nodes of a network might be more efficient than marginal external cost pricing with a high elasticity of labor supply and limited public transport coverage it is shown that the pigouvian tax rule might reduce welfare even when the generated revenue is used to finance labor tax cuts

regulation by prices quantities or both a review of instrument choice choosing appropriate policy instruments is an important part of successful regulation once objectives are agreed and suitable targets adopted policy makers can employ command and control regulation and or economic instruments and choose between fixing a price or a quantity this paper examines the relative advantages of price quantity and hybrid instruments according to their efficiency under uncertainty the trade off between credible commitment and flexibility implementation international considerations and political economy various illustrations of the theory are provided with two detailed applications to climate change and transport policy specifically congestion and safety pricing

cournot equilibrium without apology existence and the cournot inverse demand function in a multi commodity framework with absence of wealth effects we prove the existence of equilibrium for cournot oligopoly and that the concept is completely non ambiguous we also obtain a uniquely defined endogenous inverse demand function depending only on the competitive sector

when should drivers be encouraged to carpool in hov lanes policies to encourage carpooling in high occupancy vehicle hov lanes have been adopted in the united states to lower congestion and reduce air pollution we analytically model highway congestion and other vehicle related externalities encouraging carpooling decreases total costs when congestion relief in mainline lanes outweighs increased hov lane congestion importantly entry of new drivers via induced demand can negate the benefits of increased carpooling using 10 years of traffic data from los angeles we estimate time and route specific marginal external costs because costs vary substantially across routes hours and days current policies to promote carpooling will often increase social costs jel r41 r48 q53

estimating the welfare effect of congestion taxes the critical importance of other distortions within the transport system abstract this paper extends the first best analysis of peak period congestion pricing to account for interactions with other distortions within the transport system including congestion on unpriced routes accident and pollution externalities suboptimal transit pricing and gasoline taxes we illustrate how the presence of each of these distortions changes the welfare effect of a congestion tax over a wide range of parameter scenarios in all cases the welfare changes are potentially significant implying that these distortions are important to consider in an economic evaluation of congestion taxes

transactions cost economics and the multinational enterprise an assessment abstract this paper applies transactions cost principles to the multinational enterprise in order to ascertain its distinctive properties as a mode of economic organization the analysis helps identify just when and where contractual alternatives to the multinational firm are likely to be viable this turns out to depend upon the nature of the technology the regime of appropriability within which the firm operates and the characteristics of the markets in question transactions cost analysis is also extended to the multinational enterprise host country relationship implications for management and public policy are derived

reflections on the double dividend debate we survey the history of carbon taxation the range of market based instruments mbis of environmental control and the state of the double dividend debate in order to suggest directions for future research into mbis returning mbi revenues as lower distortionary taxes rather than as lump sums raises aggregate welfare but we favour mbis which raise little or no revenue for reasons of political acceptability to interest groups at the same time the overall case for any environmental improvement is weaker because of general equilibrium interactions with prior distortionary taxes research seems most necessary on quantifying the efficiency benefits of market control of heterogeneous polluters the benefits of environmental improvement the tax interaction effect and the various information costs of an mbi all on a case by case basis for different pollutants and places

green policies and public finance in a small open economy we explore the effects of greener preferences for the public finances employment and the domestic capital stock in a second best framework we find that greener preferences typically result in capital flight also employment declines despite the factor substitution that is induced by a lower tax on labour and a higher tax on natural resources if the uncompensated wage elasticity of labour supply is positive private utility declines public consumption in contrast may rise if most of the improvement in environmental quality occurs through a lower level rather than a cleaner composition of economic activity however if the labour supply curve bends backwards private utility rises while public consumption falls i introduction the deterioration of the natural environment constitutes one of the major challenges facing public policy today business groups are concerned that environmental protection induces both capital flight and major losses in private income environmental groups in contrast maintain that a more ambitious environmental policy may not impose large costs in particular environmental taxation may be attractive especially for the high tax countries of western and northern europe in these countries the

congestion and tax competition in a parallel network the purpose of this paper is to study the effects of tolling road use on a parallel road network where each link can be tolled by a different government using both theoreticaland numericalmo dels the paper analyses the potential tax competition between countries that each maximise the surplus of local users plus tax revenues in controlling local and transit transport three types of tolling systems are considered i toll discrimination between local traffic and transit ii only uniform tolls on local and transit transport are acceptable iii tolls on local users only the results suggest that the welfare effects of introducing transit tolls are large but that differentiation of tolls between local and transit transport as compared to uniform tolls does not yield large welfare differences also the welfare effects of toll cooperation between countries are relatively small in comparison with the welfare gains of non cooperative tolling of transit the numerical model further illustrates the effects of different transit shares and explicitly considers the role of asymmetries between countries higher transit shares strongly raise the transit toll and slightly decrease local tolls with asymmetric demands the welfare gains of introducing differentiated tolling rise strongly for the country with lower local demand

structural estimation of congestion costs abstract we estimate a structural model of congestion costs using a bayesian nash equilibrium approach the individual s preference for traveling depends on the anticipated level of congestion which in turn is determined by travelers decisions of mobility the model is estimated using a french transportation household survey results confirm the presence of incomplete information and show that aversion to congestion is 6 6 lower during peak times than during off peak times a traveler s willingness to pay to save 1 min in traffic is estimated at 0 73 euros during peak times and 0 25 euros during off peak times

the economics of crowding in rail transit abstract we model trip timing decisions of rail transit users who trade off crowding costs and disutility from traveling early or late with no fare or a uniform fare ridership is too concentrated on timely trains marginal cost pricing calls for time dependent fares that smooth train loads and generate more revenue than an optimal uniform fare the welfare gains from time dependent fares are unlikely to increase as ridership grows however imposing time dependent fares raises the benefits of expanding capacity by either adding trains or increasing train capacity we illustrate these results by calibrating the model to the paris rer a transit system

traffic externalities in cities the economics of speed bumps low emission zones and city bypasses abstract this paper considers various policy measures that governments can use to reduce traffic externalities in cities unlike much of the available literature that emphasized congestion we focus on measures that reduce pollution noise and some accident risks these measures include noise barriers speed bumps traffic lights tolls emission standards low emission zones and bypass capacity to guide traffic around the city center using a simple model that distinguishes local and through traffic we study the optimal use of these instruments by an urban government that cares for the welfare of its residents and we compare the results with those preferred by a federal authority that also takes into account the welfare of road users from outside the city our results include the following first compared to the federal social optimum we show that the city government will over invest in externality reducing infrastructure whenever this infrastructure increases the generalized cost of through traffic we can therefore expect an excessive number of speed bumps and traffic lights but the right investment in noise barriers second when implementing low emission zones the urban government will set both the fee for non compliance and the emission standard at a more stringent level than the federal government moreover at sufficiently high levels of through traffic the urban government will prefer imposing a toll instead of implementing a low emission zone third whatever the tolling instruments in place the city will always underinvest in bypass capacity finally if it can toll all roads but is forced to invest all bypass toll revenue in the bypass it will never invest in bypass capacity although the paper focuses on non congestion externalities most insights also hold in the presence of congestion

governance choice on a serial network this paper analyzes governance choice in a two level federation in providing road infrastructure across jurisdictions two models are proposed to predict the choice of centralized or decentralized spending structure on a serial road network shared by two districts while the first model considers simple pigouvian behavior of governments the second explicitly models political forces at both a local and central level both models led to the conclusions that the spending structure is chosen based on a satisfactory comprise between benefits and costs associated with alternative decision making processes and that governance choice may spontaneously shift as the infrastructure improves temporally

determinants of inward investment in the uk a panel analysis this paper develops an inter industry model of inward investment using a fixed effects approach this demonstrates that when inward investment is investigated in such a framework previous findings relating to the specification of measures of location advantage and ownership advantages no longer hold this also shows that there are some industries that have attracted significant inward investment over time and continue to do so while others are noticeably less successful reasons for this and potential policy measures are briefly discussed
