transfers to sustain dynamic core theoretic cooperation in international stock pollutant control international environmental agreements aiming at correcting negative externalities generated by transboundary pollution are difficult to achieve for many reasons important obstacles arise from asymmetry in costs and benefits and instability may occur due to the fact that coalitions of countries may attempt to do better for themselves outside of any proposed agreement in a static context it has already been shown that it is possible to achieve stability in the sense of the core of a co operative game by means of appropriately defined transfers between the countries involved however the transboundary pollution problems that are most important are caused by accumulated pollutants so that a dynamic analysis is required this paper provides a transfer scheme that yields a core property in a dynamic context the possibility of computing such transfers numerically is discussed

policy options to improve the effectiveness of the eu emissions trading system a multi criteria analysis abstract this paper considers several policy options which have been proposed to improve the functioning of the ets these options require an intervention either on the ets cap 30 target set aside carbon central bank long term target or on the carbon price european and national price floor we analyse the impact of each policy on the ets carbon price and emissions a multi criteria evaluation method is applied to compare the policy options against a plurality of environmental economic and procedural criteria we find that the final ranking depends on the goals to be achieved i e the relative weights attributed to the criteria when policymakers want mainly to support the carbon price both in the short and long run while improving ets flexibility and harmonization the ccb and the eu price floor are respectively ranked as first and second best options as the preference for environmental and implementation goals gradually increases the position of the eu price floor and ccb options tend to invert the 30 target should be adopted when reducing emissions is the priority goal while a national price floor is the worst option in this case nevertheless self interested states looking for a relatively quick feasible solution may find it optimal

environmental innovation and the cost of pollution abatement revisited it is widely assumed in the literature that environmental innovation reduces the marginal cost of pollution abatement in this paper we show that this is not necessarily the case and we provide some unexpected outcomes

voluntary agreements with white certificates for energy efficiency improvement as a hybrid policy instrument in this paper we examine the implementation of a combined policy scheme that consists of a traditional instrument the voluntary agreements vas and an innovative one the white certificates whc the basic structure of this scheme is that energy suppliers who undertake an energy efficiency obligation under a white certificate scheme can make use of voluntary actions to enhance investments in innovative energy savings projects energy suppliers and other market parties can additionally or in parallel participate in voluntary agreements and set energy efficiency targets for fulfilling their voluntary agreement target these market parties can receive tax exemptions or receive white certificates that they can sell in the market transaction costs and baseline definition for demonstrating energy efficiency improvement deserve special attention this policy can assist a country to enhance energy efficiency improvement while it stimulates innovation cost effectiveness can be higher than the case of stand alone policy instruments since more financing options are available for more expensive projects nevertheless the added value of the scheme lies more in the implementation of innovative measures for enhanced energy efficiency furthermore market parties can discover more business opportunities in energy efficiency and establish a green image hence an integrated scheme should achieve higher political acceptability

profit sharing and employment stability this paper tests the hypothesis that workers whose compensation packages contain a profit sharing component are less susceptible to layoff in the face of negative shocks to product demand than are workers paid a fixed time based wage the theory is tested on two data sets one a household survey and the other a survey of small businesses conducted by the authors the characteristics of profit sharing among small businesses by and large meet the theoretical requirements for stabilizing employment and the authors do find evidence in both samples to support the hypothesis the evidence however is of borderline statistical significance and is therefore more suggestive than definitive

the malleability of undiscounted utilitarianism as a criterion of intergenerational justice discounting future utilities is often justified by the ethically motivated objective of protecting earlier generations from the excessive saving that seems to be implied by undiscounted utilitarianism in productive economies we question this justification of discounting by showing that undiscounted utilitarianism has sufficient malleability within important classes of technologies any efficient and non decreasing allocation can be the unique optimum according to an undiscounted utilitarian criterion for some choice of utility function

how to design and use the clean development mechanism under the kyoto protocol a developing country perspective under the kyoto protocol industrialized countries committed to emission reductions may fullfil part of their obligations by implementing emission reduction projects in developing countries in doing so they make use of the so called clean development mechanism cdm two important issues surround the implementation of the cdm first if the cheapest abatement measures are implemented for cdm projects developing countries may be left with only more expensive measures when they have to meet their own commitments in the future the so called low hanging fruits lhf issue second a choice must be made on the type of baseline against which emission reductions are measured an absolute baseline or a relative to output one the baseline issue the purpose of this paper is to study the interactions between these two issues from the point of view of the developing country two major results are obtained first when possible future commitments for developing countries and irreversibility of abatement measures are taken into account we show that the industry where cdm projects are implemented enjoys larger profits under an absolute baseline than under a relative one second concerning the lhf problem the financial compensation required by the developing country for implementing too many cdm projects is larger under the relative baseline

rawlsian intergenerational justice as a markov perfect equilibrium in a resource technology the rawlsian maximin criterion is combined with nonpaternalistic altruistic preferences in a nonrenewable resource technology the maximin programme is shown to be time inconsistent for a subset of initial conditions a solution to this intergenerational conflict is found under a given assumption as a generically unique subgame perfect equilibrium

the environmental kuznets curve semi parametrically revisited this paper re examines the existence of an environmental kuznets curve ekc across countries using a semi parametric regression estimator which places no restrictions on the functional form our results using cross country panel data on sulfur and carbon dioxide strongly suggest that the relationship between wealth and environmental degradation is not bell shaped as suggested by an ekc rather that there is a positive link for the very poorest countries and no clear relationship for richer countries

mobility and modality trends in us state personal income we examine the mobility and modality trends in us state per capita personal income and its components during the 1929 1999 period we find strong evidence of convergence for states but that the tendency towards convergence and the associated mobility within the distribution varies during the period and especially for the 1980s our analysis of convergence by income component suggests that transfer income contributes more to the observed convergence than does asset income we also note that distributional mobility need not be accompanied by high rank mobility and find that trends toward convergence in the us have tended to preserve rank ordering cet article cherche a examiner les tendances de mobilite et de modalitequant aux revenus personnels par tete et a ses composants aux etats unis pendant la periode qui va de 1929 a1999 il s avere de fortes preuves d une convergence entre etats qui varie au cours de la periode etudiee et qui va de pair avec une variation de la mobilite associee au sein de

political consumerism and public policy good complements against market failures political consumerism has become over the past years an ever growing phenomenon by which citizens express through their consumption their political environmental and ethical opinions this paper discusses political consumerism from an economic science perspective focusing on the link between political consumerism and public policies it wonders to what extent political consumerism may represent an effective and fair instrument against market failures overall it seems that it would be better to consider it as a complement to conventional public policies

a review of the stern review on the economics of climate change the stern review calls for immediate decisive action to stabilize greenhouse gases because the benefits of strong early action on climate change outweighs the costs the economic analysis supporting this conclusion consists mostly of two basic strands the first strand is a formal aggregative model that relies for its conclusions primari ly upon imposing a very low discount rate concerning this discount rate aspect i am skeptical of the review s formal analysis but this essay points out that we are actual ly a lot less sure about what interest rate should be used for discounting climate change than is commonly acknowledged the review s second basic strand is a more intuitive argument that it might be very important to avoid possibly large uncertain ties that are difficult to quantify concerning this uncertainty aspect i argue that it might be recast into sound analytical reasoning that might justify some of the review s conclusions the basic issue here is that spending money to slow global warming should perhaps not be conceptualized primarily as being about consump tion smoothing as much as being about how much insurance to buy to offset the small change of a ruinous catastrophe that is difficult to compensate by ordinary savings

a theory of anticipated utility abstract a new theory of cardinal utility with an associated set of axioms is presented it is a generalization of the von neumann morgenstern expected utility theory which permits the analysis of phenomena associated with the distortion of subjective probability

combining voluntary agreements and taxes an evaluation of the danish agreement scheme on energy efficiency in industry abstract in this paper the danish agreement scheme on energy efficiency in industry is described and evaluated the basis for this evaluation is an implementation study of the agreement scheme and five evaluation criteria examining the practical considerations related to the choice of policy instruments a distinct feature of the danish scheme is that it is closely connected to a co2 tax on trade and industry this connection is important for the understanding and the functioning of the scheme the scheme has certain advantages the prevention of free riding is effective the scheme is flexible over time and the agreements do actually have an impact on firm behaviour but there are also drawbacks the administrative costs and search costs are high and the impact on innovation and networking among firms is low

voluntary agreements in environmental policy an empirical evaluation for the chilean case abstract in this paper the author assesses and discusses the chilean approach on voluntary environmental agreements based on a survey questionnaire performed in 322 facilities belonging to four industrial sectors the author evaluated the effectiveness and static efficiency of five voluntary agreements vas using the propensity score method the study found out that vas had a significant effect in encouraging the implementation of environmental initiatives although most of them represent incremental rather than radical improvements moreover whilst it confirms that vas can suffer from regulatory capture it also reveals that capture can coexist with significant environmental improvements in other areas regarding the static efficiency impact it suggests that vas succeeded in encouraging cost minimization in terms of operational and transaction costs furthermore this research documented that participation in an industrial association is by far the most significant variable associated with voluntary agreements and that regulatory threats and governmental funding are incentives of secondary importance finally it concludes by highlighting that the lack of public participation together with several institutional and political factors that subdue the ambitiousness of targets are the most serious drawbacks which should be addressed in order to avoid credibility issues of vas in the near future

a note on clean technology adoption and its influence on tradeable emission permits prices in this paper we give an example in which the price of tradable emission permits increases despite firms adoption of less polluting technology a result that is in contrast with montero j environ econ 44 23 44 2002 and parry j regul econ 14 229 254 1998 among others if two cournot players switch to a cleaner technology the price for permits may increase due to an increase in the net demand for permits and a decrease in the net supply of permits after the clean technology is adopted this is only the case when output demand is quite elastic

unjust intergenerational allocations abstract an intergenerational allocation is defined to be unjust if there is a feasible allocation with more total consumption and less relative inequality unjust allocations are characterized in technologies satisfying certain regularity conditions after ruling out unjust allocations the consequences of letting generations choose according to a standard form of altruistic preferences are explored in to particular classes of technologies a connection between excluding unjust allocations and maximizing the welfare of the worst off generation is established in these technologies

constraining equitable allocations of tradable co2 emission quotas by acceptability since the signing of the kyoto protocol future commitments are likely to be framed in terms of tradable quotas the discussions on the allocation of the quotas among countries will be based at least partly on rules corresponding to a certain conception of equity for instance allocating quotas in direct proportion to population in relation to gdp or according to past emissions has been advocated taking a long term perspective we compute such allocations of tradable quotas with a dynamic closed loop model the total amount of quotas to be distributed at each period corresponds to the world optimal amount of emissions to be realized at each period we observe that most equitable allocation rules do not make the agreement individually rational for every country along the entire time path we then propose a mechanism which determines allocations of quotas that are as close as possible to any equitable allocation while satisfying individual rationality

justifying social discounting the rank discounted utilitarian approach the popular discounted utilitarian criterion for infinite horizon social choice has been criticized on the ground that it treats successive generations unfairly i propose to evaluate intergenerational welfare with a rank discounted utilitarian rdu criterion instead the criterion amounts to discounted utilitarianism on non decreasing paths but it treats all generations impartially discounting becomes the mere expression of intergenerational inequality aversion i show that more inequality averse rdu societies have higher social discount rates when future generations are better off i apply the rdu approach in two benchmark economic growth models and i prove that it promotes sustainable policies maximizing discounted utility

increasing returns and the foundations of unemployment theory current approaches to macroeconomic theory divide roughly into two basic schools of thought one approach typically associated with rational expectations views the economy as basically at or near walrasian market clearing equilibrium in which case it becomes very difficult to explain away convincingly the undeniable persistence at times of involuntary unemployment another approach views the underemployed economy as being in a state of temporary fixed price disequilibrium in which case aside from having to repress suspicions that the essence of effective demand failure might not have to do with prices fixed at wrong values there is a lot of rationalising to be done about why profitable adjustments are so slow this paper argues that something like an internally consistent theory of steady state involuntary unemployment is possible and even plausible the cornerstone of this third approach is increasing returns to scale which blocks unemployed agents from breaking out of a low level equilibrium trap unless there is overall coordination or stimulation a simple model is presented which contains the basic ideas

a review of the stern review on the economics of climate change how much and how fast should we react to the threat of global warming the stern review argues that the damages from climate change are large and that nations should undertake sharp and immediate reductions in greenhouse gas emissions an examination of the review s radical revision of the economics of climate change finds however that it depends decisively on the assumption of a near zero time discount rate combined with a specific utility function the review s unambiguous conclusions about the need for extreme immediate action will not survive the substitution of assumptions that are consistent with today s marketplace real interest rates and savings rates

implementing the share economy in a recent series of papers and books weitzman 11 12 13 has put forward a new policy prescription for the macroeconomy in weitzman s view significant improvements in the performance of the macroeconomy can be achieved by altering key structural relationships specifically the wage contract between workers and firms weitzman labels this approach the share economy because workers wages are no longer contracted for in nominal terms but vary with an index of the firm s performance usually profits that is the workers share in the firm s success or failure the point of weitzman s work is not that participation increases worker s motivation or productivity in weitzman s view share contract wage agreements create a pool of latent excess demand for labor within firms firms then behave in the labor markets as buyers who would expand employment at the going wage if they could this contrasts with the more familiar case where firms are willing to expand employment only if the wage is reduced weitzman s claims for economies implementing share contracts are impressive lower natural unemployment rates less susceptibility to layoffs caused by macroeconomic shocks and reduced inflation in weitzman s world firms are monopolistic competitors operating under increasing returns to scale it is these two features that lead to wage and price inflexibility and therefore to potential unemployment 10 weitzman makes his case for the share economy by examining a transition economy where conversion from a wage system to an equivalent profit sharing system yields the same pay 13 945 even in this case where total payments to workers are identical weitzman shows that the share economy expands output and employment while lowering price 13 945 although conversion to a share economy may seem desirable from a macroeconomic view
