a mixed oligopoly in the presence of foreign private firms in this paper a mixed oligopoly model is considered in which a state owned public firm competes with both domestic and foreign private firms previous articles on mixed oligopoly did not include foreign private firms the effect on the equilibrium involves a lower price and a different allocation of production relative to the case when all private firms are domestically owned in addition issues such as the effects of an open door policy allowing foreign firms to enter and the effects of foreign acquisition of domestic firms are discussed

effects of indirect taxation in a mixed oligopoly abstract in a mixed oligopoly an increase in tax ad valorem or specific does not change total output but increases the output of the public firm and the tax revenue also privatization may increase both tax revenue and welfare

a uk carbon energy tax a carbon energy tax has been proposed by the european commission to start as us 3 per barrel oil equivalent in 1993 rising to us 10 in 2000 the effects of this tax on the uk economy can be assessed by using a large scale energy environment economy model in which energy demand is treated by means of aggregate equations for energy users and fuel share equations for electricity and each of the main fossil fuels the electricity supply industry is represented in the model by simulating the characteristics of each existing generating station and of a range of new station types and by allowing the model to choose the fuels used from relative fuel prices and prices of capital inputs this approach contrasts with the multimodel approach used in most studies of the effects of the tax the tax is introduced as a tax on imports and domestic output of fossil fuels in proportion to their carbon and energy content with the tax being passed on through the economic system depending on the use of the fuels thus the electricity industry is faced with higher prices for coal gas and fuel oil and chooses to burn the different fuels according to their relative prices four scenarios are developed which vary according to the way the tax revenues are recycled through reductions in vat or in income tax rates and whether the tax is introduced throughout the european community or throughout the oecd if the tax is european it is assumed that the energy intensive industries will be exempt the outcome is that the tax is sufficient to stabilize co2 emissions over the period 1990 2005 at 12 below base levels by the end of the period there is an overall saving of energy compared to base and a further switch to gas in electricity generation the effects on the macroeconomy are rather small and as the revenues are recycled rather than saved by the government gdp growth is likely to increase under the tax by some 0 2 above base this confirms other studies in which revenues are recycled but contradicts many results from studies in which revenue recycling is ignored or incomplete the effects on the energy intensive industries are expected to be small in all the scenarios but 14 of tax revenues are lost if the industries are exempt

nonrenewable resource scarcity nonrenewable resource theory often is summarized by hotelling s rule this paper reviews theoretical extensions and empirical investigations of resource extraction models observed data are often inconsistent with the hotelling rule suggesting that other characteristics of nonrenewable resource supply including exploration heterogeneous ore quality technological progress and capital investment are important determinants of the dynamic behavior of resource prices given the persistent recurrence of concern about nonrenewable resource scarcity measures of nonrenewable resource scarcity and the empirical evidence for the time trends of those measures are reviewed finally the implications of nonrenewable resource scarcity for economic growth are examined

double dividend effectiveness of energy tax policies and the elasticity of substitution a cge appraisal there is a considerable body of literature that has studied whether or not an adequately designed tax swap whereby an ecotax is levied and some other tax is reduced while keeping government income constant may achieve a so called double dividend that is an increase in environmental quality and an increase in overall efficiency arguments in favor and against are abundant our position is that the issue should be empirically studied starting from an actual non optimal tax system structure and by way of checking the responsiveness of equilibria to revenue neutral tax regimes under alternate scenarios regarding technological substitution with the use of a cge model we find that the most critical elasticity for achieving a double dividend is the substitution elasticity between labor and capital whereas the elasticity that would generate the highest reduction in carbon dioxide emissions is the substitution elasticity among energy goods

energy taxes and endogenous technological change abstract this paper studies the effects of a tax on energy use in a growth model where market structure is endogenous and jointly determined with the rate of technological change because this economy does not exhibit the scale effect a positive relation between tfp growth and aggregate r d the tax has no effect on the steady state growth rate it has however important transitional effects that give rise to surprising results specifically under the plausible assumption that energy demand is inelastic there may exist a hump shaped relation between the energy tax and welfare this shape stems from the fact that the reallocation of resources from energy production to manufacturing triggers a temporary acceleration of tfp growth that generates a shaped time profile of consumption if endogenous technological change raises consumption sufficiently fast and by a sufficient amount in the long run and households are sufficiently patient the tax raises welfare despite the fact that in line with standard intuition it lowers consumption in the short run

the organizational foundations of x inefficiency a game theoretic interpretation of argyris model of organizational learning abstract this paper addresses the issue why does x inefficiency persist in many organizations when its existence nature and causes are known and when everyone stands to gain from correcting the errors that cause it and why are some organizations able to learn while others appear not to we construct a model of persisting x inefficiency based on argyris concepts of organizational learning it is argued that organizations succeed in eliminating x inefficiency by achieving a critical mass of individuals willing to admit and correct error once achieved this critical mass may lead to a new stable and efficient equilibrium

reform of the coal sector in an open economy the case of china cheap abundant and easy to transport and store coal has been produced and consumed to meet people s energy needs the last decade s growth in global coal use has been driven mainly by developing economies like china whose phenomenal economic growth has been powered by coal fired electricity and promoted by the export of manufactured goods a recent reform focus in china s coal sector is on coal taxation the paper develops a game theoretic model tailored to the context of china where coal taxation reform takes place against the background of privatisation of coal firms and an open economy it finds that the adoption of special coal taxes is optimal for social welfare under most circumstances but may induce coal firms to commit opportunistic behaviour in the process of privatisation the paper also cautions about potential resistance to the reform from consumers coal firms and government officials

the effect of initial lease periods on price discovery in laboratory tradable fishing allowance markets abstract newly established tradable fishing allowance markets are often accompanied by a period of high price volatility these fluctuations complicate capital investment decisions and play a significant role in determining outcomes for the traders involved this paper reports an evaluation of two market design features that may reduce volatility during price discovery a uniform price auction in which all trades within a period take place at the same price and an initial lease period which prohibits permanent allowance transfers at the beginning of the program we find that initial lease periods effectively reduce volatility once permanent trading is introduced

estimating the causal effect of water scarcity on the groundwater use efficiency of rice farming in south india abstract there is no consensus among researchers on the influence of scarcity on common pool resource use some suggest that scarcity leads to prudent use whereas others suggest that it will cause over extraction of resources this issue is particularly of interest for developing countries where natural resources are becoming scarce at an alarming rate this paper investigates the causal association between water scarcity and groundwater use efficiency in a rice based cropping system in south india where groundwater is increasingly becoming a scarce resource contextualization of the work is done under the premise of reported contradictions concerning the scarcity efficiency nexus using a two stage approach the causality is estimated first farm level groundwater use efficiency gwue scores are calculated using non parametric efficiency analysis and then these inefficiencies are linked to farm level scarcity indicators using the inverse probability weighting method our results showed a negative causal association between farm level water scarcity and gwue indicating the existence of competitive appropriation behavior in the face of scarcity hence policy measures to conserve groundwater should include supply enhancement to remove the threat of immediate scarcity on farm to avoid inefficient pumping in addition to demand management measures and improved governance

exchange rate overshooting the trade balance and rational expectations abstract this paper presents a model of exchange rate determination characterized by imperfect asset substitutability between domestic and foreign bonds sticky goods market prices and rational expectations the model is used to analyze the response of the exchange rate to a step change in relative money supplies the assumption of imperfect asset substitutability permits introduction into the analysis of trade flows which respond to relative price changes these flows create non monotonic exchange rate adjustments to long run equilibrium these non monotonic adjustments are consistent with rationality and may lead to short run undershooting or overshooting

the effects of energy related policies on energy consumption in china abstract this paper examines the effects of different types of energy related policies on different types of energy consumption in china we collect and construct a novel comprehensive and detailed data set on province level energy related policies that includes specific types of energy related command and control policies financial incentives awards intellectual property rights and education and information policies our econometric method employs instruments to address the potential endogeneity of the policies according to our results some types of energy related policies have been effective in reducing energy consumption however many other policies have the possibly unintended or even perverse consequence of increasing rather than decreasing energy consumption our results on the mixed effectiveness of energy related policies in china in reducing energy consumption have important implications for the design of energy related policies in china and elsewhere

an assessment of proposed energy resource tax reform in russia a static general equilibrium analysis abstract a large part of government revenues in russia comes from royalties and export taxes on crude oil oil products and gas recently the russian government has considered reducing export taxes on crude oil and oil products compensated by an increase in the royalty on crude oil the objective of the paper is to analyse the economy wide effects of this proposal moreover a hypothetical replacement of export taxes and royalties with a pure rent tax is analysed a static single country multi sector computable generation equilibrium cge model is employed the primary findings are as follows a replacement of export taxes on crude oil and oil products with a royalty on crude oil provides substantial allocative efficiency gains but this policy is not a superior one welfare could be substantially improved when the export taxes and royalty are replaced with a pure rent tax that can be implemented in the form of a cash flow tax on the negative side reducing export taxes on crude oil and oil products results in a strong appreciation of the currency as a result domestic producers become less competitive in domestic markets and there is a massive increase in import demand

toward a theory of regulation for developing countries following jean jacques laffont s lead the efficient operation and expansion of infrastructures in developing countries is crucial for growth and poverty reduction however recent reforms aimed at improving the performance of these sectors have had limited success evidence suggests that in many instances this was because the traditional regulatory theory relied on by policymakers was not suitable for the institutional context in developing countries this article surveys more recent theoretical work focusing on problems with regulation in these countries at the heart of the survey is the work of jean jacques laffont who in the last decade of his life set about developing a theoretical framework for regulation in developing countries we consider the implications of his work which focused on the key institutional limitations faced in developing countries we then discuss where experience suggests that there are important omissions from this modeling bringing in extensions and alternative approaches pursued by other authors we conclude by summarizing the key ways in which regulatory policy will be different when institutions are weak overall we find that an understanding of the institutional context and its implications are crucial when designing a regulatory framework for developing countries

potential impacts of electricity price changes on price formation in the economy a social accounting matrix price modeling analysis for turkey recent reforms in the turkish electricity sector since 2001 aim to introduce a tariff system that reflects costs this is expected to affect the production and consumer prices of electricity the changes in electricity prices are then reflected in production costs in other segments of the economy subsequently producer and consumer prices will be affected the potential impact of the changes in electricity prices that the ongoing electricity reforms in turkey will bring about may have important implications on the price formation in economic activities and the cost of living for households this paper evaluates the potential impacts of changes in electricity prices from a social accounting matrix sam price modeling perspective it is found that based on the estimated price multipliers that prices in the energy producing sectors mining and iron and steel manufacturing sectors would be affected more severely than the remaining sectors of the economy consumer prices are affected slightly less than producer prices

the impact of resource tax reform on china s coal industry abstract contributing to approximately two thirds of primary energy consumption coal usage is the focus of china s energy policies to regulate the resource taxation system and reduce the burden of coal enterprises the chinese government launched a reform of its resource tax system in 2014 for coal introducing the ad valorem system to replace the volume based system that had been in place for the preceding thirty years to assess the impact of the tax reform this paper constructs two stage dynamic game models by taking the coal and coal fired power industries as the players the market situations of shortage and oversupply are investigated separately empirical data are collected to estimate the model parameters for numerical simulations the model results suggest that the tax reform will reduce both coal prices and the coal industry profitability if the tax levied on each ton of coal is maintained at the same level as before the reform regardless of whether the market is in a shortage or an oversupply situation however the increased buyer s power will amplify the effect of the tax reform the numerical simulations also provide an estimation of the tax rate of the ad valorem system that maintains the profit of the coal industry considering the demand and supply situations in china s coal market policy recommendations are provided to guide further reform of china s resource tax system

the impact of china s electricity price deregulation on coal and power industries two stage game modeling abstract the regulated price mechanism in china s power industry has attracted much criticism because of its incapability to optimize the allocation of resources to build an open orderly competitive and complete power market system the chinese government launched an unprecedented marketization reform in 2015 to deregulate the electricity price this paper examines the impact of electricity price deregulation at the industry level we first construct two stage dynamic game models to portrait the interaction between the coal and coal fired power industries using the models we compare analytically the equilibriums with and without electricity price regulation concerning electricity price electricity generation coal price and coal production the theoretical analyses find three regulated electricity price intervals that differentiate the reform impacts afterward we collect empirical data to estimate the model parameters the influences on the two industries in terms of market outcome and industrial profitability are simulated our results suggest that the current regulated electricity price falls within the medium interval which means deregulation will result in higher electricity price but lower coal price less coal production and less electricity generation the robustness analyses show that our results hold with respect to the electricity generation efficiency and price sensitivity of electricity demand

externalities and corrective policies in experimental markets this paper reports on the behaviour of simple laboratory markets which have an externality experiences with these markets provide some help in answering two broad questions 1 do markets with externalities behave in accordance with the law of supply and demand 2 how do the pollution tax pollution standard and pollution licenses compare as methods for correcting the externality

an analysis of the spanish electrical utility industry economies of scale technological progress and efficiency abstract in this paper we propose a model to explain the behaviour of the spanish electrical utility industry during the period 1987 1997 under the then existing regulatory system marco legal estable the paper will study the presence of economies of scale the effect of technological progress and the differences in the efficiency of the different companies within the market the paper concludes that the spanish electrical utility industry was not in fact characterized by economies of scale during this period but witnessed a great improvement in efficiency within that period all the critical market factors remind stable

sustainable management of renewable resources an experimental investigation in continuous time abstractthis study addresses one of the most basic questions in renewable resource management the ability of economic agents to exploit a renewable resource in an efficient and sustainable manner in a laboratory experiment subjects are presented with renewable resource extraction problems where optimal management will lead to a stable steady state a test of sustainability of the extraction practices shows that extraction behaviour results in steady states only 56 of the time the mode of the steady state distribution coincides with the optimal steady state extraction the trade off between accruing a higher payoff in the present and sustaining the resource for future exploitation leads to suboptimal behaviours such as initial overextraction of the resource compared to the optimal extraction policy costly downward adjustment of the extraction later in time and settling down for lower long run resource and extraction the suboptimal behaviours lead to 17 loss in efficiency on average in terms of th

an experimental analysis of optimal renewable resource management the fishery this paper experimentally studies the extraction decisions of a sole owner in a fishery the population dynamics of which behave according to the standard deterministic logistic growth model four treatments were implemented which differed in the level of information supplied to the subjects compared to the theoretic benchmark the data reveal that efficiency losses increase as the information on population dynamics and stock size deteriorates three common patterns of behaviour are identified the distribution of these patterns is significantly affected by the informational setting

china s provincial co2 emissions embodied in international and interprovincial trade trades create a mechanism of embodied co2 emissions transfer among regions causing distortion on the total emissions as the world s second largest economy china has a large scale of trade which results in the serious problem of embodied co2 emissions transfer this paper analyzes the characteristics of china s co2 emissions embodied in international and interprovincial trade from the provincial perspective the multi regional input output model is used to clarify provincial co2 emissions from geographical and sectoral dimensions including 30 provinces and 28 sectors two calculating principles production accounting principle and consumption accounting principle munksgaard and pedersen 2001 are applied the results show that for international trade the eastern area accounts for a large proportion in china s embodied co2 emissions the sectors as net exporters and importers of embodied co2 emissions belong to labor intensive and energy intensive industries respectively for interprovincial trade the net transfer of embodied co2 emissions is from the eastern area to the central area and energy intensive industries are the main contributors with the largest amount of direct co2 emissions the eastern area plays an important role in co2 emissions reduction the central and western areas need supportive policies to avoid the transfer of industries with high emissions

speculative intensity and spot and futures price variability this paper develops a simultaneous stochastic rational expectations model of futures and spot price determination using the model we find that increases in what we term speculative intensity increase spot price variability arising from storage cost shocks but decrease spot price variability arising from demand shocks in contrast increases in speculative intensity unambiguously decrease futures price variability regardless of the underlying source of disturbances we are able to develop these comparative static results because the model has a unique equilibrium

an assessment of optimal gas pricing in russia a cge approach domestic gas prices in russia are administratively regulated and they are substantially lower than export netback prices the administrative price regulation operates as an implicit subsidy on domestic gas consumption the russian government aims to liberalise domestic wholesale gas prices in the long term while the export netback parity is defined as a political objective it seems not to be a necessary target anymore the export netback parity is not economically rational for russia because the average export netback price of gas is higher than the marginal cost due to gazprom s market power in export gas markets an optimal domestic gas price is still not well defined this paper addresses this question by employing a comparative static single country multi sector computable generation equilibrium model cge the administrative regulation of domestic gas prices is explicitly modelled the main findings are as follows an increase in the domestic gas price provides economic efficiency gains the more elastic the export and domestic demand for gas the larger the welfare gains the optimal domestic gas price should be approximately 55 of the export netback price increasing the domestic gas price provides additional government revenues which can be used to reduce distortionary taxes on sectoral effects the structure of the russian economy shifts from energy toward non energy intensive sectors in response to an increase in the domestic gas price there is an increase in the export supply of gas furthermore an increase in the domestic gas price leads to a reduction in total co2 emissions

energy taxes as a signaling device an empirical analysis of consumer preferences this paper presents an econometric study dealing with household demand in sweden the main objective is to empirically examine the differences in consumer reaction to the introduction of or the change in environmental taxes main focus is on environmental taxes as a signaling device the hypothesis is that the introduction of an environmental tax provides new information about the properties of the directly taxed goods this in turn may affect consumer preferences for these goods hence altering the consumption choice the result from the econometric analysis shows that all goods have negative own price elasticities and positive income elasticities concerning the signalling effect of environmental taxes the results are somewhat ambiguous the tax elasticity for energy goods used for heating seems to be significantly higher than the traditional price elasticity whereas the opposite seems to be the case for energy goods used for transportation

age analysis of the impact of a carbon energy tax on the irish economy a computable general equilibrium model with specific detail in taxation and energy use is developed in this paper to quantify the impact of the implementation of energy taxation to reduce carbon dioxide emissions in ireland benchmark data combining physical energy and emissions data and economic data in the form of a social accounting matrix sam had to be compiled from various data sources because energy and pollution accounts from the seea are not available for ireland we find that the reduction target for energy related co2 emissions in ireland of 25 8 compared to 1998 levels can be achieved with a carbon energy tax of 10 15 euros per tonne of co2 though fuel switching is important in meeting the target this result is more sensitive to the possibilities for producers to substitute away from energy use welfare would fall but only by small percentages production and consumption patterns would change more significantly with a shift in demand from fuels with a high emission factor to energy sources with a lower carbon intensity and from energy to other commodities this paper confirms that a carbon energy tax leads to greater emission reductions than an equivalent uniform energy tax the latter has a stronger negative impact on the less polluting energy sectors whereas the carbon tax greatly stimulates the use of renewable energy and reduces the use of peat and coal the new sam the model and the application to energy taxes contribute to a better informed debate on environmental policy in ireland

overexploitation of renewable resources the role of misperceptions abstract numerous renewable resources have been exploited beyond limits for sustainable and economic development at times over exploitation has been observed even in cases where management regimes have been in place thus it seems pertinent to search for explanations beyond the theory of the commons an experiment is performed where subjects set reindeer quotas in a district where lichen has been severely depleted by preceding overgrazing all subjects err on the side of over exploitation behavior seems to be dominated by inappropriate static mental models and inefficient heuristics hence a subtle information problem is revealed

the effect of excessively elastic expectations on exchange rate volatility in the dornbusch overshooting model abstract bilson has described the empirical finding that the forward exchange rate overestimates the speed of return to equilibrium as a finding of excessive speculation and has drawn implications for the volatility of the exchange rate the present paper pursues this tack within the sticky price monetary model made famous by dornbusch it is shown theoretically that if the market overestimates the speed of adjustment the degree of overshooting is reduced in this sense excessive speculation leads to reduced volatility

economy wide effects of international and russia s climate policies abstract the objectives of this paper are to analyse the economy wide effects of international climate policy on the russian economy as well as the effects of russia s climate policy on european economies our analysis is based on a general equilibrium model that includes inertias such as imperfect sectoral labour mobility and vintage capital and has a detailed depiction of the power generation sector we found that international climate policy could reduce russia s private welfare by 1 8 annually due to lower revenues from exports of fossil fuels at the sectoral level russia could gain a comparative advantage in producing energy intensive commodities and hence russia s producers of those commodities increase their production and export supplies this could result in a carbon leakage in russia eliminating implicit subsidies on domestic consumption of gas and petroleum products could reduce russia s private welfare loss by 0 6 points and eliminate the carbon leakage nevertheless eliminating implicit subsidies on gas and petroleum products might not be sufficient to achieve the pledged emission reductions by 2030 moreover this leads to an undesirable increase in coal consumption and therefore some additional climate policy such as a carbon tax or an emission trading system might be required we also found that russia s climate policy could have positive but moderate effects on the european economies in particular countries such as lithuania slovakia and hungary benefit due to decreased export prices for gas crude oil and petroleum products from russia

the virtues of gradualism and legitimacy in the transition to a market economy this paper presents a simplified model of sectoral restructuring in eastern europe a move towards allocative efficiency is desired by the reform minded government but the shift to higher productivity which such efficiency requires would lead to massive layoffs and labour reallocation in the transition period we look at the impact of political constraints unanimity and or majority worker approval on reform proposals when the government faces a heterogeneous workforce holding private information on relative outside opportunities when the budgetary consequences of exit compensations are so important as to make partial reforms preferable to full reforms gradualism emerges as the optimum in a dynamic context without government commitment it is also shown that under democratic majority rule a government in control of the agenda of reforms can win majority approval for plans which end up hurting majority interests intertemporally by threatening to switch majorities in future reform proposals this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

the effects of energy taxes on the kenyan economy a cge analysis abstract the paper utilizes a computable general equilibrium model to evaluate the impact of the second oil price shock and consequent energy tax policies on the kenyan economy simulations show that dramatic change in energy prices and consequent changes in domestic energy consumption generate sequential feedbacks in the production process and affect economic structures terms of trade deteriorate the balance of payments deficit increases and national income falls energy import tariffs and a sales tax are effective policy instruments in controlling energy consumption and increasing government revenue both energy policies have net negative effects on other economic activities similar to those observed under the oil price shock as long as there are no other economically feasible sources of energy supplies there are economic losses associated with less petroleum product consumption in a net oil importing developing economy with oil intensive production technology

taxation of nonrenewable resources at various stages of production a general method of assessing tax policy effects in exhaustible resource industries is derived the model includes both extraction and processing by a vertically integrated firm and taxation can occur at any stage of production many of the standard results of the theoretical resource taxation literature are derived in a unified framework when stages of production are introduced it is seen that tax policy effects can differ dramatically from those predicted by the simpler model after the method of determining the effects of existing taxes is derived a procedure for designing taxes that achieve desired goals is analysed

validating energy oriented cge models although cge models have received heavy usage they are often criticized as being insufficiently validated key parameters are often not econometrically estimated and the performance of the model as a whole is rarely checked against historical outcomes as a consequence questions frequently arise as to how much faith one can put in cge results in this paper we employ a novel approach to the validation of a widely utilized global cge model gtap e by comparing the variance of model generated petroleum price distributions driven by historical demand and supply shocks to the model with observed five year moving average price distributions we conclude that energy demand in gtap e is far too price elastic over this time frame after incorporating the latest econometric estimates of energy demand and supply elasticities we revisit the validation question and find the model to perform more satisfactorily as a further check we compare a deterministic global general equilibrium simulation based on historical realizations over the 2001 2006 period during which petroleum prices rose sharply along with growing global energy demands as anticipated by the stochastic simulations the revised model parameters perform much better than the original gtap e parameters in this global general equilibrium context

decision making in patchy resource environments spatial misperception of bioeconomic models abstract we investigate the performance of subjects in a patchy resource environment in the experimental laboratory to expand the concept of stock misperception into spatial and non spatial components results indicate that substantial heterogeneity exists in the decision heuristics employed that can be used to identify subject types steady state and pulse fishing strategists while steady state strategists are only subject to spatial misperceptions pulse strategists are subject to both forms of misperception both subject groups overallocate effort to regions within the fishery that possess the highest rates of emigration inducing a spatial externality these spatial misperceptions are exacerbated by the spatial structure present

economic and welfare influences of an energy excise tax in jiangsu province of china a computable general equilibrium approach abstract in recent years although china s energy intensity has gradually decreased the total consumption of energy commodities has increased sharply levying an excise tax on energy commodities is one of the keys to control energy consumption this paper constructed a computable general equilibrium model to simulate levying an energy excise tax in jiangsu province which is one of china s strong economic provinces with lower endowments of energy resources the results show that the energy excise tax is beneficial for energy saving while levying energy will cause economic and welfare declines when at a level tax rate of 5 10 and 15 the loss of gdp will reach 0 27 0 66 and 1 13 respectively and the incomes of inhabitants and enterprises alike will decrease when the energy tax revenue used to compensate for the welfare losses suffered by inhabitants or enterprises there is a double dividend effect energy saving and increasing income moreover the simulation indicated that a 5 improvement of energy efficiency brings about a backfire phenomenon with an increase of 142 in energy consumption however when considering the cost of energy efficiency improvements the rebound effect will be significantly decreased policy suggestions are further recommended to help improve the energy policy in regard to reducing energy consumption

severance taxes and market structure in an exhaustible resource industry abstract this paper compares the effects of a severance tax on profit maximizing competitive and monopolistic firms which explore and produce an exhaustible resource the producers response to the tax are studied and the deadweight losses from the tax are calculated time paths of exploratory effort extraction and price are computed severance taxes lead both producers to reduce production and exploration and cause a shift in the time path for prices the deadweight losses from the tax are low especially in competition the losses in the monopoly case are relatively higher with the tax burden falling mainly on the monopolistic producer

mixed oligopoly with differentiated products abstract the paper analyzes a mixed oligopoly with horizontal product differentiation firms choose their location and price in a model a la hotelling with quadratic transport costs and the solution concept is a subgame perfect nash equilibrium this enables one to determine how the presence of one or several public firms competing with private ones affects social welfare and how the results depend on the total number of firms n and their relative positions it is shown that is only for n 2 or n 6 that a mixed oligopoly with one public firm is socially preferable to the private oligopoly

spot and forward rates in a stochastic model of the foreign exchange market abstract in this paper we develop a simultaneous stochastic model of spot and forward exchange rate determination under rational expectations for spot rates we find that increases in speculative responsiveness dampen the effects of trade balance shocks but exacerbate effects of interest rate shocks for forward rates though increases in speculative responsiveness dampen the effects of both trade balance and interest rate shocks the bias of the forward forecast error decreases as specualtive responsiveness increases but the expected squared error may increase

the ex post impact of an energy tax on household energy demand this paper presents an econometric study dealing with household demand for energy in the netherlands the main objective of the paper is to present an estimation of the actual impact of an already implemented energy tax introduced in the netherlands in 1996 the approach differs from the existing literature in that 1 it uses panel data for the same period in which the tax was introduced and 2 it estimates a demand function that controls for a large set of variables such as outside temperature type of house and of house insulation household cooking behavior and an extensive number of durable goods and electrical appliances the study concludes that in the short term the energy tax had a small but significant impact on energy consumption in the netherlands concretely the yearly average demand reduction was of 8 for electricity and 4 4 for gas additionally the influence of variables other than price and income on household energy demand is discussed using this information the impact that the energy tax had on household energy use can be compared with the energy reduction that could have been achieved when using other policy instruments

rent extracting tariffs and the management of exhaustible resources this paper examines the interaction between a resource exporting and a resource importing country the exporting country must choose the optimal rate of depletion of an exhaustible resource and also must decide on the allocation of the extracted resource between exports and domestic use optimal management from a national point of view entails inefficiency from a global perspective in that too little resource is exported as the supplying country exploits its monopoly power the importing country however has an incentive to extract some of the resource rent by using a tariff although rent extraction is limited by the exporter s ability to use the resource domestically the optimal tariff is positive and induces greater overall inefficiency

the effect of forward exchange on spot rate volatility under risk and rational expectations abstract this paper presents a multiperiod rational expectations model of a foreign exchange market in order to analyze the effect of introducing currency forward trading on measures of exchange rate volatility based on an optimizing approach to risk average agents it highlights how commercial traders and interest arbitrageurs behave facing exchange risk and forward contracting opportunities it is found that forward trading tends to stabilize spot exchange rates if the trade disturbance is the predominant random factor in the market while it exacerbates spot rate variability if the disturbance in the interest rate differential is the chief stochastic element

when does privatization work the impact of private ownership on corporate performance in the transition economies this paper compares the performance of privatized and state firms in the transition economies of central europe while controlling for various forms of selection bias it argues that privatization has different effects depending on the types of owners to whom it gives control in particular privatization to outsider but not insider owners has significant performance effects where privatization is effective the effect on revenue performance is very pronounced but there is no comparable effect on cost reduction overlooking the strong revenue effect of privatization to outsider owners leads to a substantial overstatement of potential employment losses from postprivatization restructuring

modeling prices in a sam structure the aim of this paper is to develop an intersectoral price model in a social accounting matrix traditionally the emphasis of the social accounting methodology has been on quantity oriented models and their income effects in contrast the authors use the social accounting matrix to develop a price model that captures the interdependence among activities households and factors and provides a complete set of accounting prices furthermore they use decomposition techniques to trace underlying general equilibrium effects copyright 1995 by mit press

the capital energy substitutability debate a new look over the last twenty years many studies have been made of the elasticity of substitution between capital and labor the reported estimates are highly variable and reveal an apparent dichotomy between cross sectional and time series studies the former suggest that capital and energy are substitutes while the latter suggest the converse all these studies reported allen partial elasticities of substitution we suggest that the morishima elasticity may be a more useful measure for the issues of concern to capital energy substitution we calculate the morishima elasticities from parameters estimated in a selection of earlier studies and find no excessive variability nor any evidence of the time series cross section dichotomy capital and energy are morishima substitutes copyright 1995 by mit press

structural path analysis and multiplier decomposition within a social accounting matrix framework the main purpose of this paper is to apply structural path analysis to a social accounting matrix sam framework because the sam is a comprehensive essentially general equilibrium data system the whole network through which influence is transmitted can be identified and specified through structural path analysis the latter provides an alternative and much more detailed way to decompose multipliers as compared with the traditional treatment of stone 1978 and pyatt and round 1979 this paper consists of five sections the first one reviews the sam framework as a basis for multiplier analysis and multiplier decomposition in particular the additive decomposition in terms of transfer open loop and closed loop effects is succinctly presented section ii applies this conventional decomposition to a sam of south korea to illustrate with eleven specific cases the effects of an exogenous injection on the endogenous accounts of the sam i e the incomes of the factors household groups and production activities section iii is devoted to the presentation of the elements of structural analysis and more particularly the transmission of economic influence within a structure finally section iv applies structural path analysis to the south korean sam and compares and contrasts the multiplier decomposition which it yields with the alternative decomposition discussed in section ii the comparison is the more significant in that the two decomposition methods are applied to the same eleven selected cases spanning a variety of sectors i e poles of origin for the injection and sectors poles of destination the empirical analysis in section iv suggests that structural path analysis applied to a sam is a potentially operationally useful technique within which a whole series of policy issues can be addressed the final section is devoted to a brief summary and conclusions

effects and mechanism of influence of china s resource tax reform a regional perspective abstract china s resource tax reform beginning with xinjiang as a pilot area in june 2010 marked a new stage in the progression of china s resource tax system based on the 2007 social accounting matrix sam for xinjiang constructed by ourselves this paper takes a regional perspective on china s resource tax reform to quantitatively calculate its degree of influence and qualitatively analyze its mechanism of influence by adopting an energy computable general equilibrium cge model and a sam price model the results show that the main significance of the reform lies in bolstering local government finances rather than energy conservation or carbon reduction this is because revenue will be transferred from resource enterprises and the central government to the local government while simultaneously the low tax rate narrow tax scope and unreasonable price mechanism will combine to prevent the reform from reaching its environmental goals promoting resource price mechanism reform and deepening resource tax reform will be two key elements of china s future energy strategies because resource enterprises will bear the increased burden caused by the reform the degree of sectoral price increases will be limited therefore the fear that resource tax reform will push up inflation is unnecessary and should not be a barrier to reform

extraction costs and the economics of nonrenewable resources the study questions the fundamental assumption of the standard aggregate exploration extraction model of nonrenewable resources that extraction costs and the level of reserves are inversely related it also raises questions about the model s conclusions regarding exploration incentives and the valuation of reserves an empirically tested disaggregate model is presented that suggests that exploration activity occurs from firms attempting to balance marginal extraction plus user costs at the intensive and extensive margins exploration is carried out until the marginal discovery cost of a deposit equals its present asset value and a u shaped price path is indicated

pricing and depletion of an exhaustible resource when there is anticipation of trade disruption this paper considers pricing and depletion of an exhaustible nonrenewable resource in an economy wherein domestic consumption is provided for by supplementing extraction from the economy s own resource stock with imports the future supply of which is not assured the socially optimal response to threat of trade disruption is a more conservationist depletion program for the domestic resource stock than would be called for if import supplies were assured to persist competitive domestic firms adopt the socially optimal conversationist program however firms anticipating domestic market power after the disruption of import supplies are revealed to overextract the domestic resource stock 33 references 2 figures

china s regional co2 emissions characteristics inter regional transfer and emission reduction policies abstract this paper analyzes the characteristics of china s regional co 2 emissions and effects of economic growth and energy intensity using panel data from 1997 to 2009 the results show that there are remarkable regional disparities among eastern central and western areas regional elasticities of per capita gdp and energy intensity on co 2 emissions which reflect the regional differences in economic development economy structure and restraining function of energy intensity decrease on the emission energy intensity reducing is more effective to emission abatement for provinces with higher elasticity of energy intensity but may not be significant for provinces with lower elasticity the inverse distribution of energy production and consumption regional unfairness caused by institutional factors like energy price and tax system result in inter regional co 2 emission transfer embodied in the power transmission the calculation indicates that the embodied emission transfer was gradually significant after 2003 from eastern area to the central and western areas especially energy production provinces in central area which leads to distortion on the emission and emission intensity the regional emission reduction targets and supporting policies should be customized and consistent with the actual situations rather than setting the same target for all the provinces

privatization policies in central and eastern europe privatization in central and eastern europe patrick bolton and gerard roland this paper assesses policies of mass privatization in germany czechoslovakia hungary and poland a central concern stemming from the analysis is that in view of the fiscal crisis facing economies in transition it is crucial for governments to try to maximize the proceeds from the sale of state assets because of the low initial level of private wealth it is important in this respect to let potential buyers borrow from the government or issue claims on future revenues obtained with the privatized assets to the government in order to pay for the privatized firms allowing for such non cash bids removes the government s incentive to delay privatization for fiscal reasons reduces its ability to squander immediately the proceeds from privatization and improves the decentralization of control by allowing less wealthy but more able bidders to buy the firms they are best suited to run

mixed oligopoly privatization and subsidization abstract this paper demonstrates three effects of domestic production subsidies in a mixed oligopoly industry regarding privatization and efficiency first if subsidies are used before and after privatization welfare is unchanged by privatization second if subsidies are used only before privatization then privatization always lowers welfare regardless of the number of private firms in the industry third the subsidy contributes to overall efficiency in a mixed oligopoly due to cost distribution effects

oil prices and the south african economy a macro meso micro analysis abstract three levels of analysis are used to track the channels by which south africa and its people are impacted by an increase of oil prices namely the macro economic level the meso economic level and the micro economic household level the paper uses an economy and energy integrated approach to quantify these different channels the approach combines a household survey dataset and an input output dataset to implement the models results indicate that the impacts on the macroeconomy are negative with gross domestic product falling and the current account balance worsening all of the industries falling into the high intensive oil use group witness an increase of their input cost that is above the economy wide average the impact of doubling paraffin prices results in poor households in rural areas and among the black population in particular witnessing an increase of their cost of living which is much higher than their corresponding highest expenditure quintile groups an increase of transport fuel hits the richer households much harder the distributional impacts of rising transport cost as a consequence of high oil and oil products prices shows that median quintile expenditure groups observe the highest impact both in urban and rural areas and especially among the black population

international r d rivalry and industrial strategy this paper presents a theory of government intervention which provides an explanation for industrial strategy policies such as r d or export subsidies in imperfectly competitive international markets domestic net welfare is improved by the capture of a greater share of the output of rent earning industries although the subsidy ridden noncooperative international equilibrium is jointly suboptimal behaviour of governments and firms is modelled as a three stage subgame perfect nash equilibrium the assumption that the government is the first player in this game allows it to influence equilibrium outcomes by altering the set of credible actions open to firms

spatial externalities and the common pool resource mechanism abstract this paper expands the common pool resource cpr game of walker et al 1990 to incorporate spatial structure with two spatially linked common pool resources subjects participated in a five player common pool resource game under three alternative spatial structures non spatial bi directional and uni directional linkages within the experiment results indicate that behavior in the uni directional cpr game yielded the highest average yields whereas those in the bi directional game were lower than in the non spatial game furthermore investment patterns in the uni directional game were proportionally lower in the sink cpr than those in the source cpr this behavior is consistent with the individual incentives of the game and highlights the importance of understanding the spatial structure present within our natural resources

not only the tragedy of the commons misperceptions of bioeconomics an exploratory search for explanations of mismanagement of renewable resources other than the theory of the commons was performed by an experiment eighty three subjects mostly recruited from the fisheries sector in norway were asked to manage the same simulated virgin fish stock one subject at a time exclusive property rights were granted to rule out the commons problem despite perfect property rights subjects consistently overinvested leading to an average overcapacity of 60 the resource was reduced by an average of 15 below its optimal level overcapacity and tough quotas resemble the situation in norwegian and other fisheries during the past few decades the likely explanation of the observed behaviour is misperception of feedback a phenomenon that occurs in many experimental studies of dynamically complex systems such misperceptions add a new and important dimension to the problem of renewable resource management beyond the commons problem

towards a national ets in china cap setting and model mechanisms abstract china is moving from regional emissions trading schemes etss to a nation wide ets although a larger ets will be more efficient the literature warns that it could make net permit selling regions worse off we use a cge model to simulate the linking of two provincial etss namely those of hubei and guangdong our simulations suggest a trade off between efficiency and equity as the richer regions typified by guangdong will benefit from linking but the poorer regions typified by hubei may lose this is because poorer provinces in china tend to be more emissions intensive and therefore likely to face a carbon price rise upon linking the costs of which may be only partially offset by trading if indeed trading is permitted we show this and explain why it is the case by improving on the stylized model suggested by adams and parmenter 2013 following atkinson 1970 we find that worsened equity from linking may dominate improved efficiency thus reducing aggregated welfare we advise more generous caps to be given to more emissions intensive and less developed regions if so as suggest our simulation results a pareto improvement could be attainable

how does tax system on energy industries affect energy demand co2 emissions and economy in china abstract energy savings and co2 emission reduction have become a major issue in recent years taxes on energy production sectors may be an effective way to save energy reduce co2 emissions and improve environmental quality this paper constructs a dynamic recursive computable general equilibrium cge model to analyze the impact of the energy tax on energy economy and environment from the perspective of tax rates and tax forms specific tax and ad valorem tax the results show that adjusting the tax system and the tax rate has important implications for energy conservation while having minor impacts on the output of other industries the impact of an increasing energy tax on the energy demand is greater than the impact on sectoral output indicating that energy efficiency will be increased to some extent the co2 reduction will increase over time when an ad valorem tax is implemented on enterprises we found that ad valorem tax has greater elasticity of economic output energy demand and co2 emission reduction the results support the direction of china s resource tax reform however we argue that it is better to increase the tax rate relatively and relax the control on energy prices so that energy efficiency will increase
