linking permit markets multilaterally we formally study the determinants magnitude and distribution of efficiency gains generated in multilateral linkages between permit markets we provide two novel decomposition results for these gains characterize individual preferences over linking groups and show that our results are largely unaltered with strategic domestic emissions cap selection or when banking and borrowing are allowed using the paris agreement pledges and power sector emissions data of five countries which all use or considered using both emissions trading and linking we quantify the efficiency gains we find that the computed gains can be sizable and are split roughly equally between effort and risk sharing

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

on the option to invest in pollution control under a regime of tradable emissions allowances optimal decisions of a firm facing the option of retrofitting its plant to reduce pollution and thereby eliminate the need to purchase emissions allowances are analysed the decision is treated as a real option with the price of pollution permits following a known stochastic process the model is formulated as a set of one dimensional partial differential equations at discrete points in time the firm owner makes optimal decisions about the retrofit including whether to mothball temporarily the model is used to analyse a firm s decision to instal a scrubber as a result of the 1990 u s clean air act jel classification q25 d81 g31 sur la possibilite d investir dans le controle de la pollution dans un regime de permis d emission de pollution echangeables commercialement ce memoire examine les decisions optimales d une entreprise face a la possibilite d adapter ses installations pour reduire la pollution et ce faisant d eliminer le besoin de se procurer des permis d emission de pollution sur le marche le decision est traitee comme une option reelle ou le prix des permis resulte d un processus stochastique connu le modele est formule sous forme d un ensemble d equations differentielles partielles a une dimension a des points discontinus dans le temps le proprietaire de l entreprise prend des decisions optimales de mise a niveau des installations y compris la possibilite de les fermer temporairement le modele est utilise pour analyser une decision d installer un epurateur suite a la mise en place de la loi americaine de 1990 clean air act

dynamic supply adjustment and banking under uncertainty in an emission trading scheme the market stability reserve abstract we study the impact of a supply management mechanism smm similar to the market stability reserve proposed in 2015 which preserve the overall emissions cap and we comment on the recent cap changing amendments we provide an analytical description of the conditions under which an smm alters the emissions abatement paths affecting the expected length of the banking period and its variability while abatement strategies of risk neutral firms solely depend on the former for risk averse firms changes in the latter would lead to higher risk premia accelerated depletion of the bank and consequently further reduction of abatement and allowance prices cancellation of part of the reserve could partially outweigh the effect on risk premia sustaining allowance prices

do oil producers act as oil igopolists in this paper the author analyzes an oligopoly model of exhaustible resource extraction and develop predictions about relative extraction patterns of different producers using the open quote oil close quote igopoly model of loury one can show that producers with large stocks produce a larger amount but a smaller percentage of their stocks than producers with small stocks the authors extend loury s model to cases where extraction costs differ among producers and where costs are a function of cumulative extraction an increase in extraction costs for a producer causes it to produce less relative to its rivals when extraction costs rise with cumulative extraction producers with large reserves tend to have lower extraction costs and a smaller ratio of cumulative production to initial reserves than producers with small reserves the authors test the predictions of the model using oil industry data and find that the empirical results are consistent with the predictions of open quotes oil close quotes igopoly theory producers with larger reserves extract a smaller share of their reserves and have lower production costs than producers with smaller reserves this pattern holds for 73 countries with oil reserves during the time period 1970 1989 and for approximately 400 us oil companies in 1983 and 1984 more the observed pattern of production for both opec and non opec producers is consistent with open quote oil close quote igopoly theory opec producers do not appear to restrain production given their level of reserves relative to non opec producers thus viewing the oil market as containing one dominant firm opec with a competitive fringe may be misleading further the pattern of extraction observed in oil markets is inconsistent with the pattern predicted by competitive theory 29 refs 5 figs 6 tabs less

the risk of policy tipping and stranded carbon assets if global warming is to stay below 2 c there are four risks of assets stranding first substantial fossil fuel reserves will be stranded at the end of the fossil era second this is true for exploration capital too third unanticipated changes in present or expected climate policy cause discrete jumps in today s valuation of physical and natural capital fourth if timing and intensity of climate policy are uncertain revaluation of assets occurs as uncertainty about future climate policy is resolved to highlight these four effects we use an analytical model of investment in exploration capital with intertemporal adjustment costs reserves depletion and market capitalization and calibrate it to the global oil and gas industry climate policy implements a carbon budget commensurate with 2 c peak warming and we allow for immediate or delayed carbon taxes and renewable subsidies the social welfare ranking of these instruments is inverse to that of the oil and gas industry which prefers renewable subsidy and delaying taxes for as long as possible we also pay attention to how the legislative risk of tipping into policy action affects the timing of the end of the fossil era the profitability of existing capital and green paradox effects

contractual responses to the common pool prorationing of crude oil production this paper examines bargaining among firms to mitigate rent dissipation following the major oil discoveries of 1926 35 because of high bargaining costs firms chose prorationing instead of consolidation and unitization and success varied the analysis also shows that prorationing took the form it did because concession such as per well quotas were required to draw in small operations and the quotas led to predictable responses regarding rent dissipation prorationing despite its costs controlled total field production and costs conserved natural reservoir energies and lengthened field life when private agreements failed the parties successfully appealed for state enforcement since similar heterogeneities influnce regulations elsewhere in the economy detailed analysis of bargaining among firms is essential for insight into the emergence of various institutional forms 33 references 3 tables

stakeholder pressures as determinants of csr strategic choice why do firms choose symbolic versus substantive self regulatory codes of conduct to encourage corporations to contribute positively to the environment in which they operate voluntary self regulatory codes src have been enacted and refined over the past 15 years two of the most prominent are the united nations global compact and the global reporting initiative in this paper we explore the impact of different stakeholders pressures on the selection of strategic choices to join srcs our results show that corporations react differently to different sets of stakeholder pressures and that the src selection depends on the type and intensiveness of the stakeholder pressures as well as the resources at hand to respond to those pressures our contribution offers a more specific and finely variegated analysis of firm stakeholder interactions

oligopoly equilibria in nonrenewable resource markets abstract most nash cournot oligopoly models of nonrenewable resources apply open loop equilibrium concepts and are based on physical resource depletion this paper studies feedback equilibria and economic depletion assuming affine quadratic functional forms the existence uniqueness and explicit solutions for the equilibria are derived for duopoly and n player oligopoly with multiple resource stocks for the cases of nonquadratic criteria we develop a numeric solution scheme for the nash feedback equilibrium this scheme is an application of a discrete time discrete state controlled markov chain approximation method originally developed for solving deterministic and stochastic dynamic optimization problems in our nash cournot equilibrium the degree of concentration in supply declines over time whereas the previous models with physical depletion and open loop equilibrium concepts predict that a nash cournot resource market will develop in the direction of monopoly supply

what determines principle based standards implementation reporting on global compact adoption in spanish firms international accountability standards have proliferated in the last 20 years with the un global compact gc as the most widely accepted principle based standard catalyzing voluntary participation by firms this study aims to improve understanding about the factors that determine companies progress in adopting principle based standards drawing on the resource based view of the firm we examine the direct and combined influences of different organizational resources firm specific resources innovative capability length of participation and internationalization of the firm on standard implementation as perceived by 213 spanish gc signatories our results reveal that the level of firm specific resources has a positive effect on the extent of gc principles implementation and that innovative capability and length of gc participation strengthen this effect contrary to our expectations we find that the internationalization of firms does not have an effect on gc principles implementation we discuss the implications of these findings for scholars and practicing managers

optimal timing problems in environmental economics abstract because of the uncertainties and irreversibilities that are often inherent in environmental degradation its prevention and its economic consequences environmental policy design can involve important problems of timing i use a simple two period model to illustrate these optimal timing problems and their implications for environmental policy i then lay out and solve a continuous time model of policy adoption in which the policy itself entails sunk costs and environmental damage is irreversible the model generalizes earlier work in that it includes two stochastic state variables one captures uncertainty over environmental change and the other captures uncertainty over the social costs of environmental damage solutions of the model are used to show the implications of these two types of uncertainty for the timing of policy adoption

design for sustainability in companies strategies drivers and needs of turkey s best performing businesses abstract experts have been developing design for sustainability tools and methods for several decades but their practical application remains challenging and varies in different contexts the limited literature on design for sustainability in turkey reflects the inadequacy of legislation market demand and companies practices nonetheless one can find good examples of design for sustainability in the country this study investigates the best performing companies in turkey s sustainability field through a survey that addresses the barriers they face the benefits they achieve their further needs for achieving sustainability and the scope of and drivers for the practices findings indicate that among the design for sustainability strategies the sample companies are more active in producing and manufacturing and packaging they are driven to boost brand value and reputation but not to increase exports inadequate market demand and legislation are by far the biggest barriers companies needs to carry out sustainability activities are high but mostly with regards to research development recent results differ somewhat from the earlier findings in turkey and to a greater extent from previous studies in europe in turkey design for sustainability is still comprehended as an issue of production needing the attention and expertise of designers it can generate benefits even when its practice is limited promoting design for sustainability within the industry by providing good examples can increase its impact this study builds a background for future research on design for sustainability and for spreading its use by companies universities intermediaries and policy makers the results might be applicable to other contexts experiencing similar setbacks on sustainability as the turkish industry

natural resource economics under the rule of hotelling abstract natural resource stocks held in situ are physical assets equilibrium in the assets market requires that their rates of return be such that their owners are just willing to hold on to them rather than invest elsewhere i discuss a number of factors relating to the evolution of extraction costs to the durability of the resource to market structure and to uncertainty that are important in correctly characterizing the rate of return on holding exhaustible natural resource stocks the emphasis is put on how those factors can potentially help bridge the gap between the basic hotelling s rule of natural resource exploitation and the historical behaviour of the flow price of a number of resources i also highlight some theoretical and empirical issues that need further attention

a note on uncertainty and the hotelling rule abstract in this paper we derive the hotelling rule of optimal natural resource depletion modified to account for uncertainty in rates of return it is shown that in the presence of risk aversion the rule implies that the expected equilibrium rate of increase of net resource price must equal the expected rate of interest if and only if there exists a zero covariance between the marginal utility of consumption and the difference between the rate of net price increase and the rate of interest the sign of this covariance is an empirical question as an example illustrates

strategic growth options we provide a strategic rationale for growth options under uncertainty and imperfect competition in a market with strategic competition investment confers a greater capability to take advantage of future growth opportunities this strategic advantage leads to the capture of a greater share of the market either by dissuading entry or by inducing competitors to make room for the stronger competitor as a result of this strategic effect payoffs are in a rough sense more convex than in the case of no investment in a growth option when the strategic advantage is strong increased uncertainty encourages investment in growth options higher uncertainty means more opportunity rather than simply larger risk if the strategic effect is weak the reverse is true on the other hand an increase in systematic risk discourages the acquisition of growth options our results contradict the view that volatility is a strong disincentive for investment

institutionalizing sustainability a structural equation model of sustainable procurement in us public agencies abstract the rapidly growing interest in sustainable operations in practice has been mirrored by an equivalent expanding attention within the academic community yet as encouraging and significant as the recent growth in the area has been there is still much that needs to be done for instance there is surprisingly little empirical research on public sector management and on factors that might lead an organization to become more likely to adopt sustainable practices the scope of this research therefore is to explore the conditions under which a given organization is more likely to engage and prioritize sustainable procurement practices and to determine the extent to which the leadership style of the organization s top leader can explain the degree to which sustainability is promoted within a specific organization data collected with the help of a self administered survey from a random sample of us public agencies is analyzed using structural equation modeling among others the results of the empirical analysis confirm that the leadership style of an organization s top executive is positively associated with the probability that an agency will engage in sustainable procurement practices this research is among the first to attempt to provide an actionable model of adoption of sustainable procurement at an organizational level it contributes to the diffusion of research on sustainability by studying sustainable procurement practices adoption and by developing a model that draws simultaneously on systems theory stakeholder theory transformational leadership theory and institutional theory

institutionalizing sustainability an empirical study of corporate registration and commitment to the united nations global compact guidelines abstract drawing upon institutional and stakeholder theories we explore the causal mechanisms of institutionalization and their influence on sustainable development initiatives to test our arguments we study the registration patterns of 394 large corporations from 12 western european and latin american countries into the united nations global compact results indicate that the normative and mimetic mechanisms of institutionalization i e academe and peer influence are better indicators of sustainable development initiatives than the coercive one i e government regulation the implications of these findings are consequential if sd practices continue as an ethical choice and not a mandated obligation for corporate decision makers

politics matters regulatory events as catalysts for price formation under cap and trade this paper investigates how the political process of making cap adjustments has shaped market outcomes in the world s largest cap and trade system the eu ets capitalizing on an event study method that incorporates an econometric technique designed to handle parameter instability and model uncertainty we assess the news implied price response to 29 hand collected announcements about the eu ets supply schedule our findings document a high market responsiveness to political events and reveal how market participants view the evolution of cap stringency in the light of a particular announcement we provide evidence that a sequence of strong event induced price drops evolve in the backloading decision process which is consistent with the interpretation that market participant s confidence in the political support for reform and probably the eu ets in general has been unsettled we also document positive price reactions to the 2020 and 2030 policy packages but not the 2050 roadmaps

temporary natural resource cartels abstract we analyze the behavior of a nonrenewable resource cartel that anticipates being forced at some date in the future to break up into an oligopolistic market in which its members will then have to compete as rivals under reasonable assumptions about the value function of the individual firms in the oligopolistic equilibrium that follows the breakup we show that the cartel will then produce more over the same interval of time than it would if there were no threat of dissolution and that its rate of extraction is a decreasing function of the cartel s life that there are circumstances under which the cartel will attach a negative marginal value to the resource stocks in which case the rate of depletion will be increasing over time during the cartel phase that for a given date of dissolution the equilibrium stocks allocated to the post cartel phase will increase as a function of the total initial stocks whereas those allocated to the cartel phase will increase at first but begin decreasing beyond some level of the total initial stocks

a few bad apples scandalous behavior of mutual fund managers recent scandals in the business world have intensified the demand for an explanation of the causes of corporate wrongdoing this study empirically tests the effects of mutual fund management fees and control structures on the likelihood of illegal activity within mutual fund organizations specific attention is given to the presence of agency duality issues in the mutual fund industry and how this influences the motivations and decisions of fund managers findings provide support for the hypothesized relationship that higher levels of management fees decrease the likelihood of illegal behavior additionally control of the mutual fund by external management is found to have a negative impact on the likelihood of illegal activity while also acting as a moderator of the management fee illegal behavior relationship

emissions trading systems with cap adjustments abstract emissions trading systems etss with fixed caps lack provisions to address systematic imbalances in the supply and demand of permits due to changes in the state of the regulated economy we propose a mechanism which adjusts the allocation of permits based on the current bank of permits the mechanism spans the spectrum between a pure quantity instrument and a pure price instrument we solve the firms emissions control problem and obtain an explicit dependency between the key policy stringency parameter the adjustment rate and the firms abatement and trading strategies we present an analytical tool for selecting the optimal adjustment rate under both risk neutrality and risk aversion which provides an analytical basis for the regulator s choice of a responsive ets policy

endogenizing the cap in a cap and trade system assessing the agreement on eu ets phase 4 in early 2018 a reform of the world s largest functioning greenhouse gas emissions cap and trade system the eu emissions trading system ets was formally approved the reform changed the main principles of the system by endogenizing the emissions cap we show that the emissions cap is now affected by the allowance demand and is therefore no longer set directly by eu policymakers as a consequence national policies that reduce allowance demand can now reduce long run cumulative emissions which is not possible in a standard cap and trade system using a newly developed dynamic model of the eu ets we show that policies that reduce allowance demand can have substantial effects on cumulative emissions after the reform model simulations also suggest that the reform reduces long run cumulative emissions and to a lesser extent reduces emissions in the short run even so the reform has a small short run impact on the currently large allowance surplus

consignment auctions of free emissions allowances abstract while the initial distribution of emissions allowances is usually thought to be independent of the emissions outcome free allocation can affect the efficiency and fairness of allowance trading inefficiency may result from thin allowance markets poor price discovery and regulatory or organizational complexities that hinder the recognition of opportunity costs concerns about fairness may result from intransparency in the process of transferring substantial allowance value we explore the role of consignment auctions in mitigating these concerns these revenue neutral auctions return the financial value of allowances to their original holders while revealing prices and directing allowances to their highest valued use they also can be used to support a minimum price when allowances are freely distributed which may facilitate program linkage consignment auctions have minimal administrative costs and do not necessarily involve government experience indicates that they can play an important role especially in new markets

covid 19 tests the market stability reserve we compare the decrease in energy demand and co2 emissions in europe during the financial crisis 2008 2009 with the expected drop in demand and emissions due to covid 19 and the price response of the eu emission trading system eu ets we ask whether the rather limited current price reduction may be due to the market stability reserve msr implemented in the eu ets between the two crises stylized facts and basic theory are complemented with simulations based on a model of the eu ets together they suggest a mixed result the msr stabilizes the eu ets price in turbulent times but imperfectly we show that the more persistent the covid 19 shock is the less the msr is able to serve its purpose

real options and preemption under incomplete information abstract this paper introduces incomplete information and preemption into an equilibrium model of firms facing real investment decisions the optimal investment strategy may lie anywhere between the zero npv trigger level and the optimal strategy of a monopolist depending on the distribution of competitors costs and the implied fear of preemption our model implies that the equity returns of firms which hold real options and are subject to preemption will contain jumps and positive skewness

online sustainability communication practices of european seaports abstract although ports have a direct and substantial impact on the social and physical environments in which they operate studies on corporate sustainability focussing on ports are scant this study investigates the under researched topic of sustainability communication practices in the european seaport sector its purpose is to analyse to what extent if any are there differences in these practices it seeks to capture the influence of national institutions and some port specific characteristics in sustainability reporting using content analysis we analysed the extent and content of corporate sustainability information disclosed in the websites of 186 european seaports we used an institutional theory framework the varieties of capitalism approach as lens of analysis multivariate ordinal regressions were used to analyse the influence of national institutions on disclosure we found that sustainability communication varies from country to country not entirely in accordance with the varieties of capitalism framework despite the majority of ports identified by our study having already included corporate sustainability topics in their online communication practices we conclude that there is still much work to be done

an intertemporal carbon emissions trading system with cap adjustment and path control abstract cap adjustment with shocks and cost effectiveness in cap and trade system has been an area of concern for regulators by a simple two period model of such system with banking and borrowing we examine how emission reduction technological changes affect the cap in three cases i e pure flow externality pure stock externality and mixed externality and identify the efficiency properties in such system with banking and borrowing we show that the effects of technological changes on cap are negative in both pure flow and pure stock externality cases in the mixed externality case the effects are uncertain which depend on the decayed rate of co2 stock the discounted rate and functions of marginal abatement costs and marginal damage in general cases the social optimum is not attainable via the cap and trade system since firms sub optimally distribute emissions across periods in a particular case if the ratio of marginal damage in period 1 to the discounted marginal damage in period 2 is exactly equal to the decayed rate the decentralized emissions of firms will lead to the social optimum finally a hybrid quantity price policy is proposed to rectify the paths of firms to be socially desirable with an effective quantity control

the geography of equity listing why do companies list abroad this paper documents aggregate trends in the foreign listings of companies and analyzes their distinctive prelisting characteristics and postlisting performance in 1986 1997 many european companies listed abroad mainly on u s exchanges while the number of u s companies listed in europe decreased european companies that cross list tend to be large and recently privatized firms and expand their foreign sales after listing abroad they differ sharply depending on where they cross list the u s exchanges attract high tech and export oriented companies that expand rapidly without significant leveraging companies cross listing within europe do not grow unusually fast and increase their leverage after cross listing foreign listings are becoming an increasingly important strategic issue for companies and stock exchanges alike as companies become global in their product market and investment strategies direct access to foreign capital markets via an equity listing can yield important benefits at the same time the international integration of capital markets has led to unprecedented levels of competition among stock exchanges in this competitive struggle the winners are the exchanges that manage to attract more foreign listings and the attendant trading volume and business opportunities despite the importance of these issues still little is known about which exchanges succeed in capturing more listings from abroad and why this question is intimately related to a second issue namely which advantages companies expect to get from a foreign listing securing cheap equity capital for new investment allowing controlling shareholders to divest on a liquid market preparing for foreign acquisitions or simply enhancing the compa

intertemporal depletion of resource sites by spatially distributed users mineral deposits and other exhaustible resources are scattered around the globe as are their users yet the theory for analyzing depletion of such resources assumes that all resource sites and all users are located in the same place when applying the theory therefore one is forced to disregard what often seems to be an important real world consideration our purpose here is to generalize harold hotelling s 1931 theory of exhaustible resources to accommodate situations in which resource sites and their users are spatially distributed our analysis has many applications it can be applied to a conventional exhaustible resource like oil alternatively it can be applied to an unconventional exhaustible resource like scarce landfill space shipments of solid waste to landfills in other states or countries have become a prominent public policy issue eduardo ley et al 2000 finally our analysis can be applied in situations where the space reflects not geographical location but characteristics of the resource e g the sulfur content hardness and so forth of coal which users find distinctive 2 only two theoretical papers in resource economics have introduced spatial considerations 3 jean jacques laffont and michel moreaux 1986 studied the extraction of resources from sites located along a line segment with all users at one end charles kolstad 1994 was the first to consider spatially distributed users in his formulation consumers are distributed uniformly along a line segment with resource sites at each end kolstad s approach although innovative requires that the set of users be parti

rushing the impatient allowance reserves and the time profile of low carbon investments postponing the issue date of allowances in a cap and trade scheme by e g a reserve mechanism impacts the time profile of low carbon investments if the postponement constrains intertemporal arbitrage short term investments increase but long term investments are deterred this effect aggravates the shortage of long term investments at least partially attributed to firms impatience the cancellation of allowances agreed for phase iv of the eu ets is suitable to counteract the negative effects of cap neutral postponement on long term investments by making the reserve redundant all effects crucially depend on how firms form expectations about future allowance prices

resources as a constraint on growth for a considerable part of its history the american economy has functioned as a cowboy economy it has been a cowboy economy in the sense that there have been no important resource constraints on growth this is not to say that land minerals and a clean environment have been freely available rather agricultural land could be obtained at roughly constant costs most essential minerals have been present at fairly high grade in considerable abundance and the environment could be used as a sink without becoming fouled in the last several decades however cropland has stayed almost constant some high grade mineral deposits have been exhausted and the carrying capacity of our environment has been strained the scarcity of resources has led many to argue that the operating rules of our economy must change whereas in the cowboy economy we could afford to use our resources profligately the new view of economic growth is that the closing of all our frontiers means that we are now operating in a spaceship economy in a spaceship economy great attention must be paid to the sources of life and to the dumps where our refuse is piled things which have traditionally been treated as free goods air water quiet natural beauty must now be treated with the same care as other scarce goods it would seem difficult to question the observation that the world economy is progressing toward a closed system many have carried this observation further describing a future imperiled by famine depleted of essential materials running out of energy or choking in its own exhaust fumes behind these pessimistic visions is a deeper skepticism about the very fruits of economic growth economists have for the most part ridiculed the new view of growth arguing that it is merely chicken little run wild i think that the new view of growth must be taken seriously and analyzed carefully what have we learned about the new view the first set of studies relates to theoretical investigations by theoretical i mean propositions based on largely untested assumptions about model structure perhaps hypothetical would be a more accurate term in this category belong the celebrated writings sponsored by the club of rome as well as many offshoots of this work jay forrester dennis h meadows et al these works have demonstrated that under certain conditions involving technology population and resource availability a sustained growth path for consumption is not possible the conclusions of these works have not generally been accepted by economists because of the dubious nature of many of their assumptions in particular the assumptions regarding population growth and technology are quite unsatisfactory several authors have shown that the conclusions of these models are not robust to minor modifications in structure thus r boyd showed that introducing a new factor called technology would drastically alter the model s path my work 1973a showed that any of three changes in model structure ongoing technological progress adequate factor substitution or population decline would lead to opposite and more optimistic results it should be stressed however that all yale university

what ails the european union s emissions trading system abstract the european union has adopted economists idea of curbing carbon emissions by establishing markets where bankable emissions allowances can be traded implicit in proofs that cap and trade minimizes the expected discounted cost of capping emissions however is that the regulator not intervene once the market is established otherwise market participants encounter uncertainties beyond what a social planner faces this paper discusses the equilibrium that results when private agents bank tradable allowances in the face of ongoing risk of future regulatory intervention and shows that the cap will be achieved at unnecessarily high cost even if no regulatory intervention actually occurs evidence that such risks are currently distorting eu ets comes from the depressed current spot price from the findings of schopp and neuhoff 2014 that speculators require multiples of the riskless rate of interest to bank permits and from the sensitivity of prices to votes and announcements about proposed future regulatory changes

political measures for strategic environmental policy with external effects this paper investigates an environmental policy designed to reduce the emission of pollutants under uncertainty with the agent problem as an optimal stopping problem we first analyze the two cases in which there are one agent and two competing agents by following ohyama and tsujimura 2005 when we consider a model of strategic agents we need to analyze the external economic effect that is peculiar to an agent s environmental policy implementation then to improve and resolve these external effects we examine three alternative political measures comprising an environmental subsidy an environmental tax and an emission trading system the results of the analysis indicate that the environmental subsidy and environmental tax promote environmental policy however they do not create an incentive to be the leader on the other hand an emissions trading system not only promotes environmental policy but also creates an incentive for leadership

governing corporate social responsibility an assessment of the contribution of the un global compact to csr strategies in the telecommunications industry csr has become an important element in the business strategy of a growing number of companies worldwide a large number of initiatives have been developed that aim to support companies in developing implementing and communicating about csr the global compact gc initiated by the united nations stands out since its launch in 2000 it has grown to about 2900 companies and 3800 members in total the gc combines several mechanisms to support csr strategies normative principles networks for learning and co operation and communication and transparency about csr activities however up to now only a few empirical evaluations of the contribution of the gc to csr strategies have been conducted that however have not differentiated between different types of companies regarding type of industry or regarding the maturity of csr this paper aims to partly fill this knowledge gap by a case study examination of three frontrunner companies in the telecommunications industry the results show that the gc is only one of the many initiatives that these companies employ in shaping implementing and reporting about their csr strategies and that its role is at most modest there are two important reasons one is that many of the csr issues that these companies deal with are industry specific and are hence addressed in specific networks the second reason is that the gc principles are perceived as minimum requirements that do not provide many incentives to the three case study companies to perform better a differentiation of norms for gc members is expected to enhance the contribution of the gc to csr strategy employment not only for frontrunner companies but as well for other categories of companies

procrastinating reform the impact of the market stability reserve on the eu ets abstract we study the impact of the market stability reserve msr on price and emission paths of the eu ets from 2019 onwards the msr will adjust the number of allowances auctioned as a function of the size of the surplus i e in times of a large surplus it shifts the issue date of allowances into the future in a perfectly competitive allowance market the msr only affects price and emission paths if the baseline equilibrium becomes unfeasible if the msr is binding prices increase in the short run but drop in the medium run relative to the baseline the msr increases price variability if uncertainty over future allowance demand is resolved while there is a surplus the long run cap is unaffected by both the msr and overlapping climate policies this contrasts the eu s objectives of improving the resilience of the eu ets and increasing synergies with overlapping climate policies
