managing without growth abstract there are three main arguments why developed countries should consider managing without growth 1 continued economic growth worldwide is not an option owing to environmental and resource constraints and so developed countries should leave room for growth in developing countries where the benefits of growth are evident 2 in developed countries growth has become uneconomic in the sense that it detracts more from well being than it adds and 3 economic growth in developed countries is neither necessary nor sufficient for meeting specific policy objectives such as full employment no poverty and protection of the environment this paper explores various growth scenarios for canada over the medium range to 2020 using lowgrow a dynamic simulation model after describing lowgrow a scenario is presented that shows conditions under which the rate of unemployment in canada could be reduced to historically low levels poverty eliminated and greenhouse gas emissions reduced to comply with canada s commitment under the kyoto protocol without relying on economic growth this is not to say that zero growth should itself become a policy objective rather that the dependence on and defence of economic growth should not be an obstacle to fulfilling more specific welfare enhancing objectives of full employment eliminating poverty and protecting the environment the paper concludes with some policy implications for managing without growth followed by an annex which provides a technical description of lowgrow

the kyoto protocol a review and perspectives international concern about climate change has led to the kyoto protocol negotiated in 1997 which contains legally binding emission targets for industrialized countries to be achieved during the commitment period 2008 2012 while proponents of the protocol celebrate it as a breakthrough in international climate policy opponents criticize that its approach namely setting targets and timetables for emission reductions is seriously flawed this paper provides a critical assessment of the protocols potential performance and discusses amendments to foster its effectiveness and efficiency it concludes that even without any effective emission reductions in the initial commitment period the ratification of kyoto is important for the further policy process of climate protection the kyoto protocol has established a flexible broad based international mechanism that provides a valuable starting point for shaping efficient climate policies in the future

tipping points and business as usual in a global commons abstract this paper analyzes a dynamic strategic model of resource extraction from a global commons countries derive benefits from both direct extraction and aggregate conservation of an open access resource each period a country s output depends both on its resource usage and on the global stock of the resource stored within the ecosystem leading examples are ocean fisheries habitat preservation forestry and land carbon biomass the production coefficients on these inputs vary across countries and evolve stochastically over time a business as usual bau equilibrium characterizes each country s resource usage in the absence of an effective international agreement under non concave resource dynamics depletion of the resource in a bau equilibrium may reach a tipping point below which the stock spirals downward toward a steady state of marginal sustainability under the assumptions of the model the tipping points emerge endogenously if the number of extractors exceeds some fixed finite bound the commons always tips regardless of the initial stock we find that countries will accelerate their rates of extraction the closer they are to reaching the low end steady state by contrast in the socially efficient plan the commons never tips if the initial stock is large

fiscal interactions and the case for carbon taxes over grandfathered carbon permits this paper provides simple formulas for adjusting the costs of carbon taxes and tradable carbon permits to account for interactions with pre existing tax distortions in the labour market both policies reduce labour supply as they increase product prices and reduce real household wages the resulting efficiency losses in the labour market can be substantial relative to partial equilibrium abatement costs however much of this added cost can be offset and perhaps more than offset when additional distortions from the tax system are considered if revenues from carbon taxes or auctioned permits are used to reduce distortionary taxes consequently there can be a strong case on efficiency grounds for using carbon taxes or auctioned permits over grandfathered carbon permits copyright 2003 oxford university press

exchange market pressure in paraguay 1963 88 monetary disequilibrium versus global and regional dependency the relevance of the monetary approach to exchange market pressure for paraguay s small open economy is compared to that of two competing keynesian structural approaches which emphasize respectively global and regional dependency effects estimation results for the three models including formal comparisons using nonnested hypothesis tests and forecast accuracy staistics suggest that the explanatory power of the monetary model is dominated by that of the regional dependency model with the global dependency model having an intermediate degree of applicability this result is intuitive given the extreme dependency of the paraguayan economy on argentina and brazil

tests of variance bounds implied by cagan s hyperinflation model within the context of a demand for money model during a hyperinflation which cagan 1956 made famous this paper examines the implied variability of the underlying variables when expectations are formed rationally a la muth 1961 the measure of variability adopted in the paper is the variance and the focus is on the derivation and testing of the implied variability of both the expectations and the realizations of real and nominal money balances and inflation rates empirical evidence is provided for the case of the german hyperinflation of 1921 1923 specifically two sets of variance bound tests are analyzed the first set model 1 investigates the implied variance bounds on the rationally expected growth rates of the underlying variables and the second set model 2 explores the bounds on the observed outcomes of the levels of these variables for the purpose of empirical implementation since the expectation variables in model 1 are unobservable they have to be inferred from the available data by invoking additional specifications not required by model 2 two expectations generating mechanisms are employed in the paper one requires conditioning expectations on the past historical values of the underlying variables the second alternative specification involves the assumption of an efficient foreign exchange market to the extent that the expected cost of holding domestic money is the expected change in the exchange rate as has been observed by frenkel 1977 1979 to be the case the forward premium on foreign exchange can be used to infer inflationary expectations the present paper may be motivated along several lines since its inception cagan s demand for money model during a hyperinflation has played an important role in studies of hyperinflations but the empirical results are not uniform 2

growing state federal conflicts in environmental policy the role of market based regulation abstract in recent years cases in which state governments chose to override federal environmental regulation with tighter regulations of their own have become increasingly common even for pollutants that have substantial spillovers across states this paper argues that this change arose at least in part because of a shift in the type of regulation used at the federal level from command and control regulation toward more incentive based regulation under an incentive based federal regulation a state imposing a tighter regulation will bear only part of the additional cost and thus has more incentive to tighten regulation than it does under federal command and control this difference helps to explain observed patterns of regulation in addition it has implications for the choice of regulatory instruments for a pollutant that causes both local and spillover damage a federal pollution tax is likely to yield a more efficient outcome than federal command and control policy or a federal system of tradable permits

optimal carbon taxes for china and implications for power generation welfare and the environment abstract china is expected to constitute about half of the world s emissions between 2010 and 2040 as concerns about climate change intensify the chinese government is poised to commit to a low carbon economy these conditions make china a suitable case in which to study how emission policies impact on energy supply welfare and the environment to achieve this purpose we incorporate abatement technologies into the gtap computable general equilibrium model and show that optimal taxes range between 0 03 for services and 2 02 for manufacturing in most cases simulated tax rates are by far higher than pollution taxes stipulated in the new chinese environmental tax law furthermore despite a decline in output of many sectors including the electricity sector overall welfare gains exist from introducing carbon taxes moreover these taxes reduce environmental pollution by approximately 62 5 in general carbon taxes are insufficient for mitigation in china and due to a coal dominant energy structure implementing these taxes leads to a decline in power generation hence the chinese aggressive investment strategy for renewable electricity technologies as stipulated in its 13th five year plan is understandable

dynamic mechanism design for a global commons we model dynamic mechanisms for a global commons countries value both consumption and conservation of an open access resource a country s relative value of consumption to conservation is privately observed and evolves stochastically an optimal quota maximizes world welfare subject to being implementable by perfect bayesian equilibria with complete information the optimal quota is first best it allocates more of the resource each period to countries with high consumption value under incomplete information the optimal quota is fully compressed identical countries receive the same quota even as environmental costs and resource needs differ this is true even when private information is negligible

negotiating a uniform emissions tax in international environmental agreements abstract a consensus appears to be emerging that a global carbon tax is the best policy for managing greenhouse gas emissions emissions tax systems are relatively straightforward cost effective and can generate revenues used to offset other distortionary taxes moreover recent theoretical research weitzman 2014 has demonstrated that under some conditions the globally efficient tax rate can be implemented through a majority voting rule we extend this area of research by examining a uniform emissions tax system in the framework of an international environmental agreement in which only countries that voluntarily participate are subject to the tax we show that in the simplest situation in which countries have identical marginal benefit and cost functions the largest stable agreement consists of two countries and the tax system has little impact on abatement levels our analysis highlights that by ignoring the participation decision and assuming commitment by all parties the efficiency gains from a uniform emissions tax system are overstated

environmental protection and the private provision of international public goods final version received 11 september 2008 international environmental protection like the combat of global warming exhibits properties of publicgoods in the international arena no coercive authority exists that can enforce measures to overcome free rider incentives therefore decentralized negotiations between individual regions serve as an approach topursue ef cient international environmental protection we propose a scheme which is based on the ideasof coasean negotiations and pigouvian taxes the negotiating entities offer side payments to counterpartsin order to in uence their taxation of polluting consumption side payments in turn are self nanced bymeans of externality correcting taxes as we show a pareto ef cient outcome can be attained

an alternate method of estimating the cagan money demand function in hyperinflation under rational expectations abstract an alternate method of estimating the cagan money demand function under rational expectations is presented the technique utilizes the side assumptions that 1 accurate contemporaneous information on the price level and money stock is available to individuals and 2 unobservable noise in the portfolio balance schedule is neglible the procedure has three main virtues first it is implemented without imposing restrictions on the money supply process second the procedure is extremely simple and economical third it admits a simple test of a restriction implied by the cagan money demand function results are related to issues in recent hyperinflation studies

the role of environmental factors in growth accounting this paper explores a relatively new methodology the directional distance function method to analyse productivity growth the method allows us to explicitly evaluate the role that undesirable outputs of the economy such as carbon dioxide and other greenhouse gases have on the frontier production process which we specify as a piecewise linear and convex boundary function we decompose productivity growth into efficiency change catching up and technology change innovation we test the statistical significance of the estimates using recently developed bootstrap methods we also explore implications for growth of total factor productivity in the oecd and asian economies copyright 2004 john wiley sons ltd

a competitive carbon emissions scheme with hybrid fiscal incentives the evidence from a taxi industry abstract as two major approaches to reduce carbon emissions command and control instruments and market based carbon trading systems have their own weaknesses our paper first proposes a type of endogenous equilibrium methodology to dynamically derive the industrial carbon emissions standards at the equilibrium the sum of all carbon assets and liabilities is zero in the considered industry moreover the standards fall over time with low carbon technological advance most importantly combining pigou s and coase s ideas we construct a fiscal instrument accounting for both carbon taxes and allowances based on the dynamically improved emissions standards and carbon trading prices this no revenue for government method implements a self operated ecology for carbon trading market finally considering the waterloo recession of carbon prices we introduce an adjustment factor into the model which generates a negative feedback mechanism with carbon prices to support our idea we present the application to beijing taxi industry in detail and raise relative policy implications based on the evidence

how can china reach its co2 intensity reduction targets by 2020 a regional allocation based on equity and development in late 2009 the chinese government committed to cut its carbon dioxide emissions per unit of gross domestic product gdp by 40 to 45 of 2005 levels by 2020 this has raised the issue of how to allocate the co2 reduction target regionally to meet the national reduction target to meet this objective the following aspects may be taken into consideration equity principles common but differentiated responsibilities intensity reduction target fulfillment and economic difference and reduction potential among provinces this paper selects per capita gdp accumulated fossil fuel related co2 emissions and energy consumption per unit of industrial added value as indicators for emission reduction capacity responsibility and potential respectively based on these three indicators a comprehensive index is developed and an intensity allocation model constructed as decision makers may have different preferences when allocating the reduction burden we allocate different weights to the indicators analyzing the results using cluster analysis the following aspects may also be considered together with the national regional development strategy to determine how to share the burden the reduction potential of various regions implementation potential of the plans and promotion of a highly efficient low carbon economic development model

altruism and global environmental taxes a global externality like the ghg emissions leading to climate change are both due to free riding at the individual level as well as the government level a government aiming to maximise domestic social welfare may make individuals internalise the damage within their country but will free ride on the damage caused to other countries only a global cooperative solution could internalise global damage entirely if individuals have altruistic concern for others but continue to believe that their consumption is negligible relative to the total they will not change their behaviour however this paper shows that in a multi country setting the global equilibrium levels of consumption for both the non cooperative and cooperative solutions are affected by altruism the key results are a that non cooperative governments maximising domestic welfare will internalise some of the damage inflicted on other countries depending on the level of altruistic concern individuals have and b the cooperative global optimum also changes as altruism leads individuals to effectively experience damage in other countries as well as the direct damage to them since altruistic concern for others may vary across countries global welfare then becomes a function of the relative levels of altruistic concern between countries

the demand for money and the variability of the rate of inflation an emperical note abstract in this note we incorporate the effect of inflation variability on the demand for money in pakistan it is found that this variable has a significant impact on money demand function our results are similar to those of klein while they differ with blejer

emission allowances and mitigation costs of china and india resulting from different effort sharing approaches to meet ambitious global climate targets mitigation effort in china and india is necessary this paper presents an analysis of the scientific literature on how effort sharing approaches affect emission allowances and abatement costs of china and india we find that reductions for both china and india differ greatly in time across and within approaches and between concentration stabilisation targets for china allocated emission allowances in 2020 are substantially below baseline projections moreover they may be below 2005 emission levels particularly for low concentration targets below 490 ppm co2 eq effort sharing approaches based on allocating reduction targets lead to relatively lower reductions for china than approaches that are based on allocating emission allowances for 2050 emission allowances for china are 50 80 below 2005 levels for low concentration targets with minor differences between approaches still mitigation costs of china including emissions trading remain mostly below global average according to literature chinese emission allowances peak before 2025 2030 for low concentration targets india s emission allowances show high increases compared to 2005 levels if emission trading is allowed financial revenues from selling credits might compensate mitigation costs in most approaches even for low concentration targets india s emission allowances peak around 2030 2040 for all concentration targets c 2012 elsevier ltd all rights reserved

after kyoto alternative mechanisms to control global warming after more than a decade of negotiations and planning under the framework convention on climate change fccc the first binding international agreement to control the emissions of greenhouse gases has come into effect in the kyoto protocol the first budget period of 2008 2012 is at hand moreover the scientific evidence on greenhouse warming strengthens steadily as observational evidence of warming accumulates the institutional framework of the protocol has taken hold solidly in the european union s emissions trading scheme ets which covers almost half of europe s carbon dioxide emissions notwithstanding this apparent success the kyoto protocol is widely seen as somewhere between troubled and terminal early troubles came with the failure to include the major developing countries along with lack of an agreedupon mechanism to include new countries and extend the agreement to new periods the major blow came when the united states withdrew from the treaty in 2001 by 2002 the protocol covered only 30 percent of global emissions while the hard enforcement mechanism in the ets accounts for about 8 percent of global emissions even if the current protocol is extended models indicate that it will have little impact on global temperature change unless there is a dramatic breakthrough or a new design the protocol threatens to be seen as a monument to institutional overreach nations are now beginning to consider the structure of climate change policies for the period after 2008 to 2012 some countries states cities companies and even universities are adopting their own climate change policies are there in fact alternatives to the scheme of tradable emissions permits embodied in the protocol the fact is that alternative approaches have not had a serious hearing among natural scientists or among policymakers what are some alternatives for global public goods there are three potential approaches command and control regulation quantity oriented market approaches and taxor price based regimes of these only the tradable quantity and the price like regimes have any hope of being reasonably efficient under a tradable quantity approach an agreement proceeds by setting limits on emissions by different countries the limits are partially or wholly transferable among countries this is the approach taken under the kyoto protocol this approach has very limited international experience under existing protocols such as the cfc chlorofluorocarbon mechanisms and somewhat broader experience under national trading regimes such as the u s sulfur dioxide regime a radically different approach is to use harmonized prices fees or taxes as a method of coordinating policies among countries this approach has no international experience in the environmental area although it has modest experience nationally in such areas as the u s tax on ozone depleting chemicals on the other hand the use of harmonized price type measures has extensive international experience in fiscal and trade policies such as with the harmonization of taxes in the european union and harmonized tariffs in international trade these thoughts on the structure of international agreements to control global warming should not be regarded as negotiating strategies

are the costs of reducing greenhouse gases from passenger vehicles negative energy models suggest that the costs of reducing carbon emissions from transportation are high relative to those for other sectors this paper discusses why taxes or equivalent permit systems to reduce passenger vehicle emissions produce large net benefits rather than costs when account is taken of a their impact on reducing other highway externalities besides carbon and b interactions with the broader fiscal system both of these considerations also strengthen the case for a tax based approach over fuel economy regulation while fiscal considerations strengthen the case for taxes over grandfathered emissions permits the paper also comments on the practical relevance of automobile fuel taxes or their policy equivalents to broader legislation intended to mitigate climate change

interior matching equilibria in a public good economy an aggregative game approach abstract if the equilibrium generated by a matching mechanism is to be the desired pareto optimal outcome it is necessary for every player to be at an interior solution at that equilibrium using the aggregative game approach developed by cornes and hartley 2003 2007 this paper analyzes the conditions under which matching mechanisms in a public good economy lead to interior matching equilibria at which all agents make strictly positive flat contributions to the public good in particular we show that the distribution of income among the agents is crucial for both the existence of interior matching equilibria and warr neutrality in the case of matching

external shocks and fiscal deficits in a monetary model of international reserve determination honduras 1960 83 results from single equation estimation of a standard monetary model suggest that central bank credit growth in excess of growth of money demand was the main source of international reserve losses in honduras during the 1960 83 period further 3 sls estimates suggest that increases in central bank credit growth were largely in response to rising external interest rates and decreases in the income terms of trade in addition income growth hence growth of money demand shows a strong positive response to the income terms of trade the fiscal deficit is found to have an insignificant impact on central bank credit growth

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

comparison of different climate regimes the impact of broadening participation so far most climate mitigation studies look at climate policy strategies in a so called first best world i e using the least expensive emission reduction options in all world regions and sectors to explore the impact of limited participation of countries we have run a set of scenarios that explore the impact of introducing a carbon tax in oecd the bric countries brazil russia india and china and the rest of the world the results show that carbon taxes can effectively reduce greenhouse gas emissions however if low greenhouse gas concentration levels are to be achieved early participation in some form of large developing countries is important to increase reduction potential it should be noted that global carbon taxes without additional assumptions lead to relatively high costs in low income regions cap and trade regimes have more flexibility to create a comparable distribution of costs amongst countries

on the economics of carbon pricing insights from econometric modeling with industry level data abstract the literature which tests the porter hypothesis by studying the role of environmental policies on innovation is not only fragmented but mostly employs broad measures of environmental regulations in order to draw consensus in this literature and sufficiently incentivize the pursuit of environmental policy objectives further contributions on the economics of environmental regulations utilizing alternative methods and data are needed therefore our analysis takes the chinese national emission trading scheme ets as specific example of such a policy in the econometric analysis chinese carbon prices from this market are used and their impact on innovation is estimated using a dynamic panel data regression the main findings are that while a carbon price appears to stimulate r d intensity innovation input the boost in r d does not result into increased sales and profits for industries innovation output high energy consuming industries have higher tendencies to innovate but this takes place at the distribution and marketing stages of the value chain however since the energy requirement at these levels is less relative to the actual production stage the energy costs saving may be limited therefore to better the economics of carbon pricing in a competitive world in which risk aversion is a possibility policies which encourage energy intensive industries to innovate at the production stage would present opportunities in general these findings contribute to our understanding of innovation behavior and have the potential to stimulate new debates in the literature

optimal emission taxes for full internalization of environmental externalities abstract the present study proposes a set of optimal emissions fees that could be used to reduce the damages caused by industrial pollution the approach we use allows for the setting of pollution taxes at their economically appropriate level in particular tax rates are computed for china india and 19 sub saharan african countries all other world regions are grouped according to income level such as low income lower middle income upper middle income and high income economies our results show that constructed optimal pollution taxes range as high as 2 9 per 1 dollar of output for heavy manufacturing in the high income countries and as low as 0 01 in the service sectors of the low income countries these results show that a full internalization of the damages in each sector calls for raising the tax rates in some sectors and lowering them in others

carbon pricing and general equilibrium under leontief production technology abstract comparing temperature and emissions data does not clearly show a relationship between the two variables going further this study combines leontief production technology with a computable general equilibrium model of global trade in order to quantitatively test the implications of mitigation policies for welfare and the environment we compute optimal emissions taxes and show that administering carbon fees reduces environmental damages by nearly 50 however there is a tradeoff effect on production which calls for caution when implementing environmental policies in general environmental benefits and resources shifting due to carbon taxes lead to welfare gains

agreeing on efficient emissions reduction we propose a simple contest based mechanism providing incentives to reduce harmful emissions to their efficient level without infringing upon productive efficiency participation in the most stylized form of the scheme is voluntary and individually rational all rules are mutually agreeable and are unanimously adopted if proposed the scheme balances its budget and requires no principal in a perhaps more realistic stochastic output version which could potentially inform policy decisions we show that the transfers required by the efficient mechanism create a mutual insurance motive that can serve as an effective rationale for the gradual formation of international environmental agreements

additional evidence on inflation variability the experience of asian countries abstract the relationship between inflation and its variability has been examined by using time series data for eight asian countries it is found that this relationship also holds for countries which have enjoyed a period of long price stability furthermore this relationship also holds for highly industrialized countries

exchange market pressure in postwar brazil an application of the girton roper monetary model this study applies lance girton and don roper s hereafter g r monetary model of exchange market pressure to the postwar brazilian monetary experience the model was designed specifically for the canadian managed float during the period 1952 62 the object of their model is to explain what they term exchange market pressure that is the pressure on foreign exchange reserves and the exchange rate when there exists an excess of domestic money supply over money demand in a managed floating exchange rate regime the basic theoretical proposition is that any such excess supply of money can be relieved by an exchange depreciation a loss in foreign reserves or in the context of a managed float by some combination of the two in this sense the g r managed float model used here is firmly rooted in the modern monetary approach to exchange rates and the balance of payments brazil provides a particularly good example for testing this approach not only because it is in many senses a unique example of a postwar managed float system but also because it can be treated as a small open economy in the sense that world prices and monetary conditions faced by brazil are taken as given this particularly suits the purpose of most modern monetary models which make this assumption and obviates the problems of monetary dependence and neutralization dealt with in the pioneering g r paper specifically the small country assumption permits us to devise a simple one country equation of managed floating which depends upon four essential ingredients 1 money demand 2 money supply 3 purchasing power parity and 4 monetary equilibrium 2 furthermore in brazil a much greater proportion of exchange market pressure was absorbed by exchange rate depreciation than in the canadian case where changes in reserves were large relative to exchange rate movements in short postwar brazil provides a singularly good opportunity to test the monetary model of exchange market pressure section i briefly states the essential elements of the monetary model and derives the equation to be tested for the brazilian experience from 1955 to 1975 section ii reports empirical results for the exchange market pressure model and section iii examines the applicability of the relative version of purchasing power parity for the time period considered section iv summarizes the results and discusses the merits of the monetary approach in light of the brazilian experience

global refunding and climate change abstract we design a global refunding scheme as a new international approach to address climate change participating in the global refunding system requires an initial payment it allows each country to set its carbon emission tax while aggregate tax revenues are partially refunded to member countries in proportion to the relative emission reductions they achieve within a given period the refunding scheme reduces the intertemporal climate change problem into a static public goods problem in a simple model we show that a suitably designed global refunding scheme achieves the social global optimum provided that all countries participate we discuss several procedures to achieve initial participation

does improved environmental quality prevent a growing economy abstract a major concern for sustainable development is how countries can lower pollution while avoiding adverse output and energy shocks since economic activities change with time we develop a dynamic applied equilibrium model to study the dynamics of co2 emissions and evaluate how the pursuit of environmental policy objectives can influence output and productivity in a surrogate country in transition under an optimal environmental policy which ensures mitigation between 38 and 50 we show that productivity projected towards the year 2075 increases slightly from between 3 8 and 6 2 to between 5 7 and 7 6 respectively the required carbon tax begins from 5 29 ton in 2020 and grows on average by 3 5 reaching up to 35 83 per ton carbon towards the year 2075 even though these tax rates ensure huge benefits for mitigation they represent marginal productivity growth and substantial output and consumption costs in other words improved environmental quality presents opportunities for multifactor productivity mfp but this productivity improvement is too marginal to offset the compliance costs of the carbon tax thereby causing output to decline hence to ensure maximum economic dividend from carbon pricing especially in transitional economies measures are required to improve the innovation benefits of carbon taxes towards levels that offset the compliance costs of environmental regulations otherwise caution should be taken by developing countries in their environmental policy designs especially when boosting consumption and economic growth is a major priority

cheaper oil a turning point in paris climate talk abstract the 2015 paris climate conference is designed to achieve a legally binding agreement on climate change for the first time in over 20 years however the participants face a much tougher task in striking a new deal after the disappointing preparatory climate change talks in lima however falling oil prices have created more room to maneuver for the forthcoming global climate talks than previously thought average global oil prices have plunged from usd 110 per barrel in june 2014 to approximately usd 60 per barrel in may 2015 with the sharply falling oil prices and the downward pressure on gas and coal prices both the removal of fossil fuel subsidies ffs and the implementation of a carbon tax could be conducted without raising energy costs a growing body of research suggests that removing ffs and implementing a carbon tax could significantly reduce carbon emissions thus the approximately 50 drop in oil prices has provided a window of opportunity to reduce carbon emissions by removing ffs and internalizing climatic externalities worldwide as this window will not last forever both these measures should be implemented quickly and be considered central to the paris climate change conference compared with the lack of success in the previous two decades of climate diplomacy these two measures constitute technical and economic factors that will make a difference in the 2015 un climate change conference

sustaining the emerging carbon trading industry development a business ecosystem approach of carbon traders abstract this paper explores how carbon traders nurture the business ecosystem to sustain the emerging carbon trading industry development we collected primary data from a multinational carbon trader and its ecosystem partners in china through the construction of interviews and documentary the research findings show the carbon trading industry has experienced four stage evolution with different driving forces the carbon trader attracted and organized ecosystem partners to facilitate the cdm project owners to create carbon credits and trade them a systematic business ecosystems approach through the lens of context cooperation and configuration initiated by carbon traders has facilitated the industry development our findings also implicate to industrial practitioners and policymakers for sustaining the emerging industry development at both the current and the post kyoto protocol periods

automobile externalities and policies this paper discusses the nature and magnitude of externalities associated with automobile use including local and global pollution oil dependence traffic congestion and traffic accidents it then discusses current federal policies affecting these externalities including fuel taxes fuel economy and emissions standards and alternative fuel policies summarizing insofar as possible the welfare effects of those policies finally we discuss emerging pricing policies including congestion tolls and insurance reform and summarize the appropriate combination of policies to address automobile externalities

participation and duration of environmental agreements we analyze participation in international environmental agreements in a dynamic game in which countries pollute and invest in green technologies if complete contracts are feasible participants eliminate the holdup problem associated with their investments however most countries prefer to free ride rather than participate if investments are noncontractible countries face a holdup problem every time they negotiate but the free rider problem can be mitigated and significant participation is feasible participation becomes attractive because only large coalitions commit to long term agreements that circumvent the holdup problem under well specified conditions even the first best outcome is possible when the contract is incomplete
