re framing the urban blight problem with trans disciplinary insights from ecological economics abstract similar to circumstances in the field of economics market fundamentalism dominates urban blight policy spaces in the u s despite criticisms of the paradigm unlike the unified alternative that ecological economics ee provides to conventional economic theory however disagreement over the meaning of blight has prevented a commonly held pre analytic vision and policy agenda from forming in critical blight scholarship this paper asserts that applied ee offers a framework in which to develop such a vision and to strengthen the inchoate critical blight policy stream we draw on the ee theory and concepts to argue that blight can be understood as a stock that accumulates in an urban system as a result of underinvestment into real property our conceptualization of the problem has several important implications for public policy a brief illustration compares the relative efficacy of one city s characteristically neoliberal blight policies with more ee consistent policies in a second city to show that the latter might in fact outperform the former

a decision model for financial assurance instruments in the upstream petroleum sector the main objective of this paper is to deepen the discussion regarding the application of financial assurance instruments bonds in the upstream oil sector this paper will also attempt to explain the current choice of instruments within the sector the concepts of environmental damages and internalization of environmental and regulatory costs will be briefly explored bonding mechanisms are presently being adopted by several governments with the objective of guaranteeing the availability of funds for end of leasing operations regulators are mainly concerned with the prospect of inheriting liabilities from lessees several forms of bonding instruments currently available were identified and a new instrument classification was proposed ten commonly used instruments were selected and analyzed under the perspective of both regulators and industry surety paid in and periodic payment collateral accounts letters of credit self guarantees investment grade securities real estate collaterals insurance policies pools and special funds a multiattribute value function model was then proposed to examine current instrument preferences preliminary simulations confirm the current scenario where regulators are likely to require surety bonds letters of credit and periodic payment collateral account tools

reexamination of stock price reaction to environmental performance a garch application abstract this paper examines how the corporate environmental performance of a firm evaluated by the nikkei environmental management ranking survey affects the ranked firms stock price using the market model that accounts for generalized autoregressive conditional heteroskedasticity garch effects accordingly we compare the results of the egarch model with that of ordinary least squares ols for a period of eight years and for each year the obtained results indicate that the stock prices of firms ranked above thirty in nikkei environmental management ranking have risen fallen or remained constant on the event day the findings based on the analysis by the period of eight years suggests that market reaction to corporate environmental performance has a positive effect for the higher frequency of ranking and a negative effect for the lower frequency of ranking

general equilibrium when economic growth exceeds discounting abstract after dropping the standard general equilibrium assumption that preference orders discount future consumption faster than the economy grows and dropping continuity and weakening utility representation we establish commodity prices and consumptions that approach approximate equilibrium to within any practical tolerance the weizacker overtaking criterion defines the best known non standard discounting orders we admit over discrete time deterministic consumption paths and over continuous time stochastic consumption processes we also perturb preferences to qualify all approximate equilibrium as full equilibrium thus showing some well known non existence examples are singular and so are inadequate defence of standard assumptions journal of economic literature classification numbers c60 c62

economies with many commodities we discuss the two fundamental theorems of welfare economics in the context of the arrow debreu mckenzie model with an infinite dimensional commodity space as an application we prove the existence of competitive equilibrium in the standard single agent growth model

european environmental taxes and charges recent experience issues and trends abstract the use of environmental taxes and charges in oecd countries increased by over 50 between 1987 and 1994 while revenues raised by environmental taxes and charges remain small relative to overall taxation they comprise a rising proportion in most european countries several european countries have either undertaken or are considering systematic shifts in taxes away from labour and onto the use of environmental resources potential negative effects on competitiveness and regressive distributional effects are the major cause of concern with regard to the introduction of environmental taxes a number of ways of mitigating such effects exist and have been implemented

stock price responses to the eco points programme for electrical household appliances evidence from japan abstractthis article examines the japanese government s project for green consumer electronics to promote business through the use of eco points and its economic impact on consumer electronics firms stock prices there has been little research on the economic effect of this project in order to achieve our aim we employ event study methodology our results show that stock prices responded positively to programme adoption thereby indicating that the programme had positive effects on the related firms performance the results also show that the programme s economic effects gradually decreased over each subsequent programme extension this probably occurred because the programme targeted durable goods which consumers do not replace frequently

opening the policy window for ecological economics katrina as a focusing event abstract ecological economics and its allied trans disciplinary fields are well established in academia but so far have failed to have significant influence on policy makers public policy research and theory suggest that three process streams must converge in order to shape the political agenda and change policy kingdon j 1984 agenda alternatives and public policies boston little brown first the problem stream emerges when an existing condition is defined as a problem a discrepancy between current reality and a desired goal and critical policy makers accept the definition of the problem the policy stream emerges as consensus grows around policy instruments to solve the problem the politics stream emerges as the national mood and leading politicians accept the gravity of the problem and are willing to implement the policies required to address it when these three streams converge a policy window is created that can move issues onto the political agenda and into formal policy a focusing event like katrina can bring these three process streams together however different strategic representations of the situation may allow entirely different problem definitions and policies to dominate the political agenda this paper analyzes the extent to which katrina has opened a policy window for ecological economics we find that katrina has strengthened the three streams necessary to create a policy window for ecological economics but that the dominant economic paradigm currently on the political agenda market fundamentalism is strategically presenting katrina as supporting its own problem stream and policy stream key elements of the ecological economic agenda such as investing in natural capital are making it on to the political agenda but overall market fundamentalist policies appear likely to dominate we argue that ecological economists have failed to galvanize public acceptance for the policy goals of sustainable scale and just distribution thus failing to effectively communicate their perspectives on problem definition and or policy solutions to policy makers and the voting public we conclude with suggestions for how ecological economists can still take advantage of the katrina window and better prepare for future windows opening

stock market s reaction to disclosure of environmental violations evidence from china the stock market s reaction to information disclosure of environmental violation events eves is investigated multi dimensionally for chinese listed companies including variables such as pollution types information disclosure sources information disclosure levels modernization levels of the region where the company locates ultimate ownership of the company and ownership held by the largest shareholder using the method of event study daily abnormal return ar and accumulative abnormal return car are calculated under different event window for examining the extent to which the stock market responds to the eves furthermore statistical significance of the difference in stock market reaction is compared between event firms with different characteristics the relationship between car and its impact factors is examined by multivariate analysis the findings reveal that the average reduction in market value is estimated to be much lower than the estimated changes in market value for similar events in other countries demonstrating that the negative environmental events of chinese listed companies currently have weak impact on the stock market

aggregation of heterogeneous time preferences we examine an economy whose consumers have different discount factors for utility possibly not exponential we characterize the properties of efficient allocations of resources and of the shadow prices that would decentralize such allocations we show in particular that the representative agent has a decreasing discount rate when as is usually posited all of a group s members have a constant discount rate and decreasing absolute risk aversion preferences we also identify conditions that lead the representative agent to have a rate of impatience that decreases with gross domestic product per capita

arbitrage bubbles and valuation the standard present value rule of asset pricing may fail in financial markets when infinitely many assets can be traded i provide an example of asset payoffs and prices such that prices are arbitrage free and could be equilibrium prices in frictionless markets using valuation theory methods i show that asset prices can be meaningfully decomposed into a fundamental value and a pricing bubble the fundamental value obeys the present value rule

detecting money market bubbles the existence of a self financing trading strategy that replicates the money market account at a fixed future date at a lower cost than the current value of this account constitutes a money market bubble mmb understanding whether a market exhibits an mmb is crucial in particular for derivative pricing an mmb precludes the existence of a risk neutral probability measure the benchmark approach allows to study mmbs and is formulated under the real world probability measure it does not require the existence of a risk neutral probability measure using a range of well known stochastic volatility models we study the existence of an mmb in the us economy and find that the us market exhibits an mmb for all models considered that allow it this suggests that for derivative pricing and hedging care should be taken when making assumptions pertaining to the existence of a risk neutral probability measure less expensive portfolios are likely to exist for a wide range of long term derivatives as typical for pensions

ecological economics of coastal disasters introduction to the special issue abstract coastal disasters are increasing in frequency and magnitude measured in terms of human lives lost destroyed infrastructure ecological damage and disrupted social networks hurricane katrina and the indian ocean tsunami illustrate the severe and widespread impacts of such disasters on human well being the proximate cause of most of these disasters is forces of nature however human decisions driven largely by economic forces do much to aggravate these natural disasters for example coastal mangroves and wetlands protect coastal communities from wave surges and winds but are rapidly being converted for the production of market goods and anthropogenic climate change driven by the energy use of our economy may exacerbate coastal disasters in several ways the goal of economics should be to improve the sustainable well being of humans our well being is generated in part by the production of market goods and services but also by the goods and services provided by nature by social networks and norms by knowledge and health in short built natural social and human capital respectively in seeking to increase human well being solely by maximizing the monetary value of market goods built capital our current economic system may be doing more to undermine our sustainable well being than to improve it a point made clear by the growing negative impacts of coastal disasters an economic system should allocate available resources in a way that equitably and efficiently provides for the sustainable well being of people by protecting and investing in all four types of capital this is what ecological economics seeks to do this article introduces ten papers that apply the four capital framework to the analysis of coastal disasters seeking to understand their impacts and how to mitigate them how to predict and plan for them and how to use this information to redesign coastal areas in a more sustainable and desirable way

nature in economics nature has been ill served by 20th century economics when asked economists acknowledge nature s existence but most would appear to deny that she is worth much if ecologists worry about the contemporary nexus between population size and growth the standard of living and the natural environment we economists point to the accumulation of capital and technological progress and say malthus got it wrong in this paper i show by an appeal to theory that economics has been so badly misused that it has deflected attention from deep problems at the nexus that are faced both regionally and globally

the shading and distancing of commerce when internalization is not enough abstract a political economy of degradation and of sustainability should account not only for the full range of production costs but the sources of those costs it should consider how the pursuit of wealth can deliberately or not lead to uncounted costs and unaccountable actors this article explores the conditions of cost generation and externalization especially those that are largely unintended and inadvertent it shows how the pursuit of wealth the expansion of markets the mobility of capital and the entanglements of production processes can lead to the unwitting generation and displacement of costs it analyzes competitive business strategy and patterns of production and consumption for their contribution to such costs business strategy and state policy tend to create a never ending search for frontiers however simulated and however unecological they may be the costs generated in those frontiers are a function of shading that is obscuring of costs and distancing the separation of production and consumption decisions both of which impede ecological and social feedback and create cognitive institutional and ethical lags between initial benefits and eventual full costs as distance increases along dimensions of geography culture bargaining power or agency negative feedback loops are severed stakeholders expand while decision making contracts environmental problems are displaced and shading and cost externalization increase the likelihood of sustainable resource use increases as distance is lowered as institutions locate decision authority in those who receive negative ecological feedback and who have the capacity and incentives to act on that feedback and as the burden of proof for economic interventions shifts to the interveners

the case for methodological pluralism abstract ecology and economics share the same greek root both address complex systems ecology consists of numerous approaches to understanding natural systems energetics population biology food web models hierarchy theory to mention just a few within ecology field knowledge and the reporting of new observations are well respected economics on the other hand is dominated by one pattern of thinking and standard of proof the market model and econometrics within economics field knowledge and observations per se are little valued agreement on a correct method is frequently taken as an indication of the maturity of a science the argument is developed in this paper that all the aspects of complex systems can only be understood through multiple methodologies the agreement on method within economics however seems to reflect stronger pressures within the discipline for conformity than for truth relative to ecology since ecological economics seeks to understand a larger system than either economics or ecology seeks to understand a diversity of methodologies is appropriate and pressures to eliminate methodologies for the sake of conformity should be avoided

the limited political influence of ecological economics a case study on dutch environmental policies abstract although the ecological economics ee discourse attempts to influence environmental policy empirical studies have concluded that its success in this endeavour has been limited thus far in the netherlands however two ee related policy concepts environmental utilisation space and ecological footprint were strongly present in environmental policy during certain periods in time but subsequently disappeared from the environmental agenda the central question of this article is how these ups and downs of the ee concepts can be understood which factors determine their rise on and fall from the policy agenda over time to answer this question this article offers a conceptual model informed by the approaches in political science on framing agenda setting and knowledge utilisation we conclude that the interplay of concept specific characteristics the formation of coalitions around the concept and contextual variables explain the rise and fall of the aforementioned concepts a match between the dominant policy frame and the core elements of the concept provides the opportunity for the two concepts to be pushed on the agenda we observe the alternation of constraining frames which allows for ee concepts to survive and reconciling frames which block agenda entrance for ee concepts furthermore the alternation of these frames seems to correlate with economic and public environmental attention cycles in the netherlands

the ecological economics of land degradation impacts on ecosystem service values abstract we use two datasets to characterize impacts on ecosystem services the first is a spatially explicit measure of the impact of human consumption or demand on ecosystem services as measured by the human appropriation of net primary productivity hanpp derived from population distributions and aggregate national statistics the second is an actual measure of loss of productivity or a proxy measure of supply of ecosystem services derived from biophysical models agricultural census data and other empirical measures this proxy measure of land degradation is the ratio of actual npp to potential npp the hanpp dataset suggests that current demand for npp exceeds supply at a corresponding ecosystem service value of 10 5 trillion per year the land degradation measure suggests that we have lost 6 3 trillion per year of ecosystem service value to impaired ecosystem function agriculture amounts to 2 8 of global gdp with global gdp standing at 63 trillion in 2010 all of agriculture represents 1 7 trillion of the world s gdp our estimate of lost ecosystem services represent a significantly larger fraction 10 of global gdp this is one reason the economics of land degradation is about a lot more than the market value of agricultural products alone

an economy with infinite dimensional commodity space and empty core abstract we present an example of a two person pure exchange economy having an infinite dimensional commodity space and without core allocations

blocking efficacy of small coalitions in myopic economies abstract we consider a continuum economy with infinitely many commodities and show that for any positive e the core of the economy coincides with the set of allocations which are not blocked by any coalition with measure less than e actually our main result is an extension of grodal s 1972 econometrica40 581 583 result and therefore schmeidler s 1972 econometrica40 579 580 result to economies whose commodity space is l for myopic preferences journal of economic literature classification numbers c71 d51

liquidity and asset market dynamics this study analyzes economies with an essential role for liquid assets in the exchange process the model can generate multiple stationary equilibria across which asset prices market participation capitalization output and welfare are positively related it can also generate a variety of nonstationary equilibria even when fundamentals are deterministic and time invariant including periodic chaotic and stochastic sunspot equilibria with recurrent market crashes some equilibria have asset price trajectories that resemble bubbles growing and bursting endogenous private and public liquidity is also introduced sometimes it is efficient to provide enough liquid assets to satiate demand other times it is not

choices without prices without apologies valuing is usually regarded as a process of compressing information about attributes into a single metric armed with this reduced form of compact information the consumer can consider a particular object with a particular price attached or implied and make an informed decision but the process of valuing is less straightforward than we ordinarily suppose when environmental goods and services become the object of information compaction it is possible that important information is lost we comment on the choice problem germane to environmental goods and services and challenge the presumption that environmental choices made without explicit pricing are inferior to those in which hypothetical valuation studies are undertaken

infinite horizon incomplete markets the model of general equilibrium with incomplete markets is a generalization of the arrow debreu model which provides a rich framework for studying problems of macroeconomics this paper shows how the model which has so far been restricted to economies with a finite horizon can be extended to the more natural setting of an open ended future thereby providing an extension of the finite horizon representative agent models of modern macroeconomics to economies with heterogeneous agents and incomplete markets there are two natural concepts of equilibrium over an infinite horizon which prevent agents from entering into ponzi schemes that is from indefinitely postponing the repayment of their debts the first is based on debt constraints which place bounds on debt at each date event the second is based on transversality conditions which limit the asymptotic rate of growth of debt the concept of an equilibrium with debt constraint is a natural concept of equilibrium for macroeconomic analysis however the concept of an equilibrium with transversality condition is more amenable to theoretical analysis since it permits the powerful techniques of arrow debreu theory to be carried over to the setting of incomplete markets in an economy in which agents are impatient expressed by the mackey continuity of their preference orderings and have a degree of impatience at each date event which is bounded below a concept defined in the paper we show that the equilibria of an economy with transversality condition coincide with the equilibria with debt constraints an equilibrium with transversality condition is shown to exist it follows that for each economy there is an explicit bound m such that an equilibrium with explicit debt constraint m exists in which the constraint is never binding this latter property ensuring that the debt constraint whose objective is to prevent ponzi schemes does not in itself introduce a new imperfection into the model over and above the incompleteness of the markets

available capital utilized capital and shadow prices in inclusive wealth accounting abstract previously accounting for comprehensive or inclusive wealth has focused on the supply side of capital assets however human well being created by capital assets inherently depends on the demand side as well in particular if capital is not utilized at its full capacity then realized or actual human well being may be less affected by available capital than by effective or utilized capital in principle this notion is embodied in a shadow price which is defined as the marginal contribution of capital assets to social well being the shadow price becomes higher if the underlying resource allocation mechanism improves in practice one can account for such underutilization by adjusting shadow prices to reflect only the utilized quantity of the capital in question furthermore capital utilization has different nuanced implications for produced human and natural capital and its implications even vary across some classes of natural capital within this line of theoretical thought we provide empirical estimates of the changes in inclusive wealth and sustainability of selected developing countries in recent years by comparing available and utilized capital assets we find that sustainability assessments may be revised based on utilized capital due to among others human capital underemployment and non renewable natural capital accessibility

the consumption based capital asset pricing model the paper provides conditions on the primitives of a continuous time economy under which there exist equilibria obeying the consumption based capital asset pricing model ccapm the paper also extends the equilibrium characterization of interest rates of cox ingersoll and ross 1985 to multi agent economies we do not use a markovian state assumption this work provides sufficient conditions on agents primitives for the validity of the consumption based capital asset pricing model ccapm of breeden 1979 as a necessary condition breeden showed that in a continuous time equilibrium satisfying certain regularity conditions one can characterize returns on securities as follows the expected instantaneous rate of return on any security in excess of the riskless interest rate the security s expected excess rate of return is a multiple common to all securities of the instantaneous covariance of this excess return with aggregate consumption increments this common multiple is the arrow pratt measure of risk aversion of a representative agent rubinstein 1976 published a discrete time precursor of this result the exis tence of equilibria satisfying breeden s regularity conditions had been an open issue we also show that the validity of the ccapm does not depend on breeden s assumption of markov state information and present a general asset pricing model extending the results of cox ingersoll and ross 1985 as well as the discrete time results of rubinstein 1976 and lucas 1978 to a multi agent environment since the ccapm was first proposed much effort has been directed at finding sufficient conditions on the model primitives the given assets the agents preferences the agents consumption endowments and in a production econ omy the feasible production sets conditions sufficient for the existence of continuous time equilibria were shown in duffie 1986 but the equilibria demonstrated were not shown to satisfy the additional regularity required for the ccapm in particular breeden assumed that all agents choose pointwise interior consumption rates in order to characterize asset prices via the first order conditions of the bellman equation interiority was also assumed by huang 1987 in demonstrating a representative agent characterization of equilibrium an approach exploited here the use of dynamic programming and the bellman equation aside from the difficulty it imposes in verifying the existence of interior 1 financial support from the national science foundation is gratefully acknowledged we thank

the value of biodiversity markets society and ecosystems the value of biodiversity is discussed at different levels including market value non market values to humans and the value of biodi versity to ecosystems the main conclusion is that although market exchange values of environmental services may be used to justify biodiversity protec tion measures it must be stressed that exchange value constitutes a small portion of total biodiver sity value the total value of existing biodiversity is largely unknown but indications are that it is essen tial to human existence the various levels of biodi versity value point to the need for a hierarchical and pluralistic methodology to determine appropri ate policies for its preservation jel q21 i introduction among ecologists there is a general con sensus that biodiversity1 is of critical impor tance to the health of ecosystems and even for the long term survival of the human species there is also a consensus that bio diversity is being lost at a rate which is a cause for concern 2 economists on the other hand generally view biodiversity as just an other good which is to be placed in the basket of market choices just as any other the discussion of the specifics of biodiver sity policy has been unsatisfactory partly because of the different meanings of the word value used by economists and ecolo gists many ecologists fail to understand the logic of market allocation and why biologi cal resources are used in seemingly irra tional ways many economists fail to ap preciate the narrowness of the concept of economic value as indicated by relative prices determined by market exchange fol lowing anderson 1966 and brown 1984 the discussion below considers economic measures of value to be species of the genus assigned value which belongs to the family value many biologists and paleontologists be lieve that we are at a critical point in the history of the human species and perhaps even in the 600 million year history of com plex multicelled life on earth if the paleon tologists and biologists who study the phe nomenon of mass extinction are correct the current human induced mass extinction may be of the same order of magnitude as the five other major extinction episodes which destroyed between 20 and 96 percent of existing species on the planet ehrlich and ehrlich 1992 ward 1994 wilson 1992 we are living in a truly remarkable period in earth s 41 billion year history the valua tion decisions our species has made in the recent past and will make during the next few decades will determine the fate of life on earth for the next tens of millions of years it is critical to clarify the language and concepts we use to estimate the value of biodiversity and thus policies leading to its destruction or preservation the importance attached to the issue of biodiversity preservation necessarily in volves ethical judgments about duty to fu ture generations and responsibility toward the nonhuman natural world although in dividuals hold a variety of conflicting beliefs about human responsibility to the natural world this does not mean that policy choices

pollution accumulation and abatement policy in a supply chain abstract this paper seeks to determine how the double marginalization phenomenon affects the tradeoff between polluting emissions and abatement activities related to pollution accumulation in a supply chain composed of one manufacturer and one retailer the environmental consequence of this inefficiency which emerges in a non cooperative vertical setting governed by a single parameter contract is overlooked in the literature on pollution control in the setup of a two stage game we investigate the impact of double marginalization for non cooperative equilibrium to check whether there are differences between dynamic and strategic effects of double marginalization on pollution accumulation both the open loop and feedback nash equilibria are derived over a finite time horizon with the cooperative solution as a benchmark

the roles of stakeholder support and procedure oriented management on asset recovery abstract as the management of returned products is fast becoming a business trend caused by pressure for compliance asset recovery is increasingly viewed as a fertile area for firms to reduce cost and improve quality environmental management is a viable approach for chinese manufacturers to respond to the escalating international quest for conserving the environment to tackle the problem of rising raw material costs and to improve product quality by analyzing returned products to reach the goals of cost reduction and product quality improvement manufacturers need to understand how asset recovery can be leveraged through procedure based practices and stakeholder support to enhance performance product type characterized by different levels of demand uncertainty and time to market may affect the outcomes of asset recovery adoption and should also be taken into account drawing on the environmental management and business logistics literature we provide empirical insights on asset recovery adoption using survey data collected from export oriented chinese manufacturers we find that asset recovery and stakeholder support are complementary in strengthening manufacturers financial performance regardless of product type in addition the performance impact of asset recovery can be substantial when manufacturers environmental management practices are less procedural allowing flexibility in the logistics management of product flows

on fragility of bubbles in equilibrium asset pricing models of lucas type abstract in this paper we study the existence of bubbles for pricing equilibria in a pure exchange economy a la lucas with infinitely lived homogeneous agents the model is analyzed under fairly general assumptions no restrictions either on the stochastic process governing dividends distribution or on the utilities possibly unbounded are required we prove that the pricing equilibrium is unique as long as the agents exhibit uniformly bounded relative risk aversion a generic uniqueness result is also given regardless of agent s preferences a few pathological examples of economies exhibiting pricing equilibria with bubble components are constructed finally a possible relationship between our approach and the theory developed by santos and woodford on ambiguous bubbles is investigated the whole discussion sheds more insight on the common belief that bubbles are a marginal phenomenon in such models journal of economic literature classification numbers c61 c62 d51 g12

are there rational bubbles in foreign exchange markets evidence from an alternative test abstract this paper employs the kalman filter technique to estimate and test for stochastic bubbles for exchange rates between the us dollar and the british pound the japanese yen and the deutsche mark i find no significant evidence of bubbles my results are in sharp contrast with previous findings on exchange rate bubble testing and cast some doubt on those claims that the dollar exchange rates were driven by speculative bubbles in the post bretton woods period

analysis of existing building energy saving policies in japan and china building sector accounts for a large percentage of the total national energy consumption in most of the countries thus it is critical to formulate and implement appropriate energy saving policies in the building sector this paper focuses on energy saving policies in the building sector by conducting a comparative study between japan and china the exiting building energy saving bes policies actual effectiveness of policy implementation and obstacles to the effective policy implementation are compared in sequence related policies are categorized into four groups control and regulatory instruments economic market based instruments fiscal instruments and information and voluntary actions policy effect analysis identifies that bes policies have promoted building energy saving in both japan and china obstacles comparison reveals that japan and china shared many obstacles including high transaction costs and lack of applicable methodology compared with japan china is suffering more obstacles such as inefficient enforcement insufficient levels of information and awareness and immature financial regulation system based on the previous findings common suggestions for overcoming these obstacles of bes policies in japan and china are presented such as the accurate methods of baseline identification and emission accountings innovative incentives and more capacity building activities distinct suggestions for japan and china are also added by considering their own situations so that both countries can further improve their bes policies

3 d sustainability an approach for priority setting in situation of conflicting interests towards a sustainable development abstract this paper aims to provide a new approach to objectively assess hierarchies and priority setting in the relationship between environmental social and economic sustainability within sustainable development after a literature review several widely used conceptual figures diagrams describing this relationship were assessed using swot analyses in order to identify the major weaknesses in these pictorial descriptions based on the findings a new concept called 3 d sustainability has been developed and is presented visually as well as is described in the text this concept introduces and ranks criteria for the assessment of hierarchies within and conflicts of interests between social environmental and economic sustainability the three dimensions of sustainability these criteria are applied to several existing hierarchies and solutions to conflicts of interests based on the swot analyses the main shortcomings of the widely used conceptual figures were identified as 1 misinterpretation of embeddings 2 misjudgement of equity between the three dimensions of sustainability 3 a lack of expression of limitations and 4 lack of adequate decision support these shortcomings are overcome theoretically and in practice by 3 d sustainability a slightly more complex but conceptually richer figure than the widely used conceptual figures assessed in particular the shift of the burden of proof within the three sustainability dimensions is argued as a main solution the application of the criteria of 3 d sustainability to several real examples indicates its usefulness in decision support while justifying more sustainable hierarchies and solutions in the settlement of conflicts of interests within the three sustainability dimensions

technological progress and sustainable development what about the rebound effect abstract sustainability concepts that rest on the idea of resource or energy efficiency improvements due to technological progress tend to overestimate the potential saving effects because they frequently ignore the behavioral responses evoked by technological improvements efficiency improvements also affect the demand for resources and energy and often an increase in efficiency by 1 will cause a reduction in resource use that is far below 1 or sometimes it can even cause an increase in resource use this phenomenon is commonly labeled the rebound effect which is well known among energy economists but never attracted much attention in ecological economics the paper starts with the traditional neoclassical analysis of the rebound effect in a partial equilibrium framework that concentrates on the demand of one particular energy service such as mobility or room temperature it also provides an overview of some of the main empirical studies based on this model that mostly confirm the existence of the rebound effect but are controversial about its actual importance however we have to go beyond the neoclassical single service model in order to take care of the variety of possible feedback affecting energy use the paper presents two important expansions of the single service model in order to show the potential relevance of the rebound effect to ecological economics first it is shown that in a multi services model it proves to be difficult to make general statements about the relevance of the rebound effect in this case the overall effect of an increase in energy efficiency on total energy use depends on the on the assumptions about the substitutability between the services considered and the direction of the income effect second the paper also tries to take care of the fact that changes in resource use or energy use are frequently just side effects of other forms of technological progress especially technological change of a time saving nature can have a large influence on energy use as many time saving devices for example faster modes of transport require an increase in energy consumption that is frequently reinforced by a rebound effect with respect to time this effect will be especially strong when wages are high and at the same time energy prices are low as is currently the case in most industrialized countries consequently the paper also provides a strong argument for the introduction of energy taxes

taxes subsidies and insurance as drivers of united states coastal development abstract ever increasing coastal populations in the united states and worldwide are putting growing quantities of people and property at risk due to coastal disasters at the same time poorly planned development policies and practices erode the natural capital of coastal regions eliminating existing landscape protection from intense wind and waves government tax subsidy and insurance policies can encourage or discourage particular forms of development in the u s there is no consistent set of incentives or disincentives for coastal development and many programs have ambiguous or contradictory goals federal programs are highly fragmented being administered by a variety of government agencies state and local governments can also implement policies to improve coastal disaster protection but often fail to do so in other cases state and local policies designed for local economic growth work against the goals of federal policy increasing flood damage risk while relying on federal aid once disaster does strike these programs frequently lead to perverse subsidies where economically inefficient policies degrade natural capital and foster economic inequality in this study we evaluate the existing tax subsidy and insurance structures that led to coastal development patterns on the u s gulf coast over the last sixty years and propose alternative policies that could create a more sustainable just economically efficient and storm adaptive region

rational asset pricing bubbles this paper provides a fairly systematic study of general economic conditions under which rational asset pricing bubbles may arise in an intertemporal competitive equilibrium framework our main results are concerned with nonexistence of asset pricing bubbles in those economies these results imply that the conditions under which bubbles are possible including some well known examples of monetary equilibria are relatively fragile this paper is concerned with the conditions under which asset prices in an intertemporal competitive equilibrium are equal to the present value of the streams of future dividends to which each asset represents a claim according to a central result of the theory of finance this is very generally true in the case of economies with trading at only a finite sequence of dates as long as there are no restrictions upon transactions other than that associated with possible incom pleteness of the set of securities that are traded the result is sometimes called the fundamental theorem of asset pricing here we consider the extent to which such a result continues to be valid in the case of trading over an infinite horizon it has often been observed in the econometric literature on asset pricing bubbles that it is possible in principle for the price of a perpetuity and the dividends on that security to satisfy at all times a present value relation for one period holding returns while the security s price nonetheless does not equal the present value of the stream of dividends expected over the infinite future in such a case the price of the perpetuity is said to involve a bubble component 2 joint stochastic processes for which this component is nonzero are sometimes argued to characterize existing assets for a recent example see froot and obstfeld 1991 but such an inference depends upon aspects of the stochastic

confidence and the real value of money in an overlapping generations economy we demonstrate that stochastic bubbles which have a constant exogenous probability of collapsing may exist in general equilibrium on an intrinsically useless and unbacked asset money this may happen provided that the probability q that the bubble will persist next period is large enough and exceeds a threshold level q which we call the minimum rate of confidence this condition is always violated when the economy without bubble is dynamically efficient it is more likely to be satisfied in dynamically inefficient economies the larger the size of the inefficiency as measured by the excess of the growth rate over the no bubble interest rate we study both exchange and production economies

the identity of ecological economics retrospects and prospects the paper first reveals the relevance of ecological economics in the time of a triple crisis ecological social and economic and promotes it as a distinct paradigm comprised of two interconnected and interdependent aspects the qualitative framework within which it operates and the quantitative models and techniques it uses to observe ecosystem resilience measure progress towards sustainability and evaluate policies while acknowledging the progress that has so far been made the paper argues that divergences in understanding the meaning and content of ecological economics hinder its effectiveness and influence on real world policy making and calls for a unified framework as a common ground that would strengthen the field and direct research the implication of this position then follows pointing out what has so far been missing from the ecological economics analysis and what should be done for it to become a more problem oriented and policy relevant alternative copyright oxford university press

the impact of environmental management on firm performance environmental management has the potential to play a pivotal role in the financial performance of the firm many individuals suggest that profitability is hurt by the higher production costs of environmental management initiatives while others cite anecdotal evidence of increased profitability a theoretical model is proposed that links strong environmental management to improved perceived future financial performance as measured by stock market performance the linkage to firm performance is tested empirically using financial event methodology and archival data of firm level environmental and financial performance significant positive returns were measured for strong environmental management as indicated by environmental performance awards and significant negative returns were measured for weak environmental management as indicated by environmental crises the implicit financial market valuation of these events also was estimated cross sectional analysis of the environmental award events revealed differences for first time awards and between industries first time award announcements were associated with greater increases in market valuation although smaller increases were observed for firms in environmentally dirty industries possibly indicative of market skepticism this linkage between environmental management and financial performance can be used by both researchers and practitioners as one measure of the benefits experienced by industry leaders and as one criterion against which to measure investment alternatives

event studies in economics and finance the event study is an important research tool in economics and finance the goal of an event study is to measure the effects of an economic event on the value of firms event study methods exploit the fact that given rationality in the marketplace the effects of an event will be reflected immediately in security prices thus the impact can be measured by examining security prices surrounding the event in this paper event study methods are described including some of the potential complications an example is included to illustrate the approach

finitely optimal allocation in countably large square exchange economies abstract a countably large square exchange economy is said to be of overlapping generations type if an allocation can be pareto improved upon through a trade involving only a finite number of agents if it can be improved upon through a trade involving only finite numbers of agents and commodities a necessary and sufficient condition is given for economies to be of overlapping generation type

edgeworth equilibria in production economies abstract an edgeworth equilibrium is an allocation that belongs to the core of every n fold replica of the economy in this work we study the properties of edgeworth equilibria for economies with production and infinite dimensional commodity spaces under some relatively mild conditions we establish among other things that 1 edgeworth equilibria exist 2 every edgeworth equilibrium is a quasi equilibrium and 3 an allocation is an edgeworth equilibrium if and only if it can be decentralized by a price system

reviewing the business case for corporate social responsibility new evidence and analysis this study complements previous empirical research on the business case for corporate social responsibility csr by employing hitherto unused data on corporate social performance csp and proposing statistical analyses to account for bi directional causality between social and financial performance by allowing for differences in the importance of single components of csp between industries the data in this study overcome certain limitations of the databases used in earlier studies the econometrics employed offer a rigorous way of addressing the problem of endogeneity due to simultaneous causality although the study s results provide no evidence that there is a generic or universal business case for csr they indicate that there is a strong link between single stakeholder related issues of csr and financial performance however the analysis does not establish causality within these relationships

quality awards and the market value of the firm an empirical investigation this paper empirically investigates the impact of winning a quality award on the market value of firms by estimating the mean abnormal change in the stock prices of a sample of firms on the date when information about winning a quality award was publicly announced we note that the abnormal returns generated by the quality award winning announcements provide a lower bound for the impact of implementing an effective quality award improvement program our results show that the stock market reacts positively to quality award announcements statistically significant mean abnormal returns on the day of the announcements ranged from a low of 0 59 to a high of 0 67 depending on the model used to generate the abnormal returns the reaction was particularly strong for smaller firms mean abnormal returns ranged from low of 1 16 to a high of 1 26 and for firms that won awards from independent organizations such as malcolm baldrige philip crosby etc mean abnormal returns ranged from a low of 1 31 to a h

quasi equilibria for growth economies abstract we find preferences that discount utility from future consumption yet violate the standard growth condition in representative agent endowment economies such economies have no competitive equilibria but have quasi equilibria the supporting price systems include a type of speculative bubble

searching for sustainability the poverty of spontaneous order abstract traditional approaches to sustainability rely on models that depend upon judgments of welfare across future generations right prices and some sense as to what future persons will find giving of utility these models both accept the spontaneous order of market processes and rely on that order to derive optimal consumption paths into the future sustainability is however not a problem of divining optimal paths predicated upon right prices rather sustainability to be operational requires a prior constructed order predicated upon rights for future persons and duties for those now living who sit in a position as dictator over the settings and circumstances that will be passed on to future persons rights based approaches to sustainability do not rely upon unknowable preferences of future persons but rather upon an environmental regency in which those now living agree to preserve settings and circumstances for the future this reminds us that the issue of sustainability concerns not how much to preserve but what to preserve

event study methodologies and the size effect abstract this study of 862 press recommendations demonstrates that the size effect can distort longer term performance measures and hence event studies relative to similar sized companies post publication performance is neutral however market adjustments the capm and market model with equally or capitalization weighted indexes all produce biased results event studies are most exposed to such bias when the measurement interval is long event securities differ systematically in size or weighting from the index constituents the size effect is large and or volatile and when capm type methodologies are used these distortions are avoided by explicitly controlling for size

informal regulation of pollution in a developing country evidence from india abstract recent policy discussions recognise the limitations of formal regulations to stem pollution in developing countries as a result there is a growing interest in the potential of informal regulations to achieve environmental goals in india many polluting industries fall under the rubric of the unorganised sector in such a context localised pollution may be influenced by discussions and reports on pollution in the vernacular press this study attempts to test the hypothesis that the press can act as an informal agent of pollution control this hypothesis is tested using monthly water pollution data from four hot spots in the state of gujarat india for the period 1996 to 2000 the results show that the press can function as an informal regulator if there is sustained interest in news about pollution however not all pollution agents are affected by pollution news press coverage appears to mainly influence industrial estates with a mix of small medium and large industries

sustainable growth criteria minimum benchmarks and scenarios for employment and the environment abstract the relationship of economic growth and environmental impact has spurred fierce debates between growth optimists referring to the phenomenon of the environmental kuznets curve and pessimists referring to the limits to growth however no operational set of simple criteria has been developed so far to assess the sustainability of a given growth pattern this is all the more true for measures combining environmental and social criteria the paper undertakes to sketch out such criteria and to assess them by applying them to transdiciplinary sustainability scenarios and model simulations with panta rhei one of the most complex models of the german economy theoretical considerations as well as the empirical work with the model demonstrate that there are indeed trade offs between economic growth and environmental impacts and a positive correlation of growth and employment nonetheless it is still possible to develop carefully orchestrated strategies that combine economic competitiveness low unemployment rates and an easing of the pressure on the environment social and technical innovation reduced working time a modernised social security system green taxes and salary increases proportional to labour productivity growth are essential parts of any such strategy the triple effectiveness of such strategies regarding environmental social and economic sustainability is demonstrated by the model runs

general equilibrium wariness and efficient bubbles abstract wary consumers overlook gains but not losses in remote sets of dates or states as preferences are upper but not lower mackey semi continuous bewley s 1972 4 result on existence of equilibrium whose prices are not necessarily countably additive holds wariness is related to lack of myopia and to ambiguity aversion and therefore to bewley s 1986 6 work on knightian uncertainty wary infinite lived agents have weaker transversality conditions allowing them to be creditors at infinity and for bubbles to occur in positive net supply assets completing the markets there are efficient allocations that can only be implemented with asset bubbles

arbitrage martingales and bubbles abstract viability of security prices implies linear valuation of payoffs but if there exist an infinite number of securities or trading dates does not imply the existence of a risk neutral probability since countable additivity may fail an example is given

stock dividends stock splits and signaling this paper provides evidence that firms signal their private information about future earnings by their choice of split factor split factors are increasing in earnings forecast errors after controlling for differences in pre split price and firm size furthermore price changes at stock dividend and split announcements are significantly correlated with split factors holding other factors constant and with earnings forecast errors these correlations suggest that management s choice of split factor signals private information about future earnings and that investors revise their beliefs about firm value accordingly the analysis also suggests however that announcement returns are significantly correlated with split factors after controlling for earnings forecast errors this suggests that earnings forecast errors measure management s private information about future earnings with error that split factors signal other valuation relevant attributes or that a signaling explanation is incomplete researchers have long puzzled over the role of stock splits and stock dividends a stock dividend or split increases the number of equity shares outstanding but has no effect on shareholders proportional ownership of shares it is therefore puzzling that firms engage in these transactions and even more so that stock prices rise on average when these transactions are announced as grinblatt masulis and titman 1984 document the significant positive announcement effects led grinblatt masulis and titman hereafter gmt to hypothesize that firms signal information about their future earnings or equity values through their split decisions to date this hypothesis has met with limited support gmt conclude that the announcement returns cannot be explained by forecasts of imminent increases in cash dividends because they observe similar stock price behavior in firms that do not pay dividends our study provides further evidence on the signaling hypothesis by testing whether stock dividends and splits convey information about future earnings and by testing whether the split factor itself is the signal the notion that the split factor may act as a signal has institutional as well as theoretical support practitioners have long contended that the purpose of stock splits is to move a firm s share price into an optimal trading range baker and gallagher 1980 who surveyed chief financial officers of firms that split their shares report that 94 of their sample indicated their stock splits moved their

ends in view the capabilities approach in ecological sustainability economics while traditional scientific endeavor seeks to avoid the problem ecological economics and the broader emergent field of sustainability economics e se are explicitly grounded in a particular ethico moral assertion one that defines sustainability as a normative notion about the way how humans should act towards nature and how they are responsible towards one another and future generations baumgartner and quaas 2010 p 445 thus e se is neither a purely positive science nor is it a purely normative endeavor but it is what has been called relevant science baumgartner and quaas 2010 p 447 a key objective of e se is therefore said to be to study how ecosystems and human activity interrelate in terms that extend beyond functional and descriptive analysis of this interrelationship and towards explicitly incorporating this normative vision the result that is aimed for is a discipline that is constituted as the best possible approach to the science and management of sustainability

endogenous discounting wariness and efficient capital taxation abstract when the discount factors that infinite lived consumers use at each date are not predetermined but are instead chosen within some set depending on what the consumption plan is impatience might not hold more precisely if the utility is the infimum of discounted utilities over that set of discount factor sequences then preferences may be just upper semi impatient such lack of lower semi impatience which we refer to as wariness consists in neglecting distant gains but not distant losses examples are the precautionary case a concern with the worst lifetime outcome and the habit persistence case a concern with a fall in living standards the implementation of efficient allocations by trading assets sequentially requires taxes that avoid excessive savings by raising the opportunity of cost of saving up to the point of matching the marginal benefit of dishoarding at distant dates taxes on equilibrium plans are zero in many contexts

planning for the long run programming with patient pareto responsive preferences ethical social welfare functions treat generations equally and respect pareto improvements to non null sets of generations there are perfect optima for such preferences generations facing the same circumstances choose the same actions and all circumstances are treated as possible if each stationary policy determines a unique long run distribution that is independent of the starting point then there is a recursive formulation of policies that are simultaneously optimal for all of the preferences studied here when the ergodic distribution can depend on early events hysteresis the curvature of the social welfare function determines the risks that society is willing to undertake and leads to a variant of the precautionary principle

envisioning shared goals for humanity a detailed shared vision of a sustainable and desirable usa in 2100 economics has been defined as the science of allocation of scarce resources towards alternative ends this definition implies that the first step in economic analysis is to determine what ends are desirable for society most sectors of the society would agree that sustainability is a desirable end but there is little agreement as to what a sustainable future would look like the university of maryland institute for ecological economics sponsored a democratic future search process designed to create a relatively detailed shared vision of a sustainable and desirable usa in the year 2100 this paper presents the vision developed at that conference examines the resources required to achieve the vision and assesses the suitability of market mechanisms for allocating the required resources towards the desired ends we find that markets are not efficient mechanisms for allocation in this case and propose the institutions of a strong democracy as a promising alternative 2002 elsevier science b v all rights reserved

bubbles and constraints on debt accumulation it is commonly thought tirole econometrica 50 1982 1163 1182 that bubbles cannot occur in deterministic sequential market economies with a finite number of infinitely lived agents this paper shows that the constraint on debt accumulation which make possible the existence of equilibrium can cause bubbles if agents face a wealth constraint bubbles can exist if and only if the assest is in zero net supply if agents face exogenous short sales constraints bubbles can exists if and only if some agent s endowment grows at a rate larger than the rate of return and the short sales constraint binds that agent infinitely often

bubbles and charges the definitions of fundamental value and speculative bubbles that are standard in macroeconomics and finance are given formal representations as the countably additive part and the purely finitely additive part a measure and a pure charge respectively of the supporting price system when the commodity space is lx examples illustrate that rational bubbles can occur in standard general equilibrium models with complete markets and a finite number of agents even in the absence of uncertainty consider an economy which includes securities or capital goods which are claims to cash flows over countably infinite time and also includes markets for all goods conduct the following thought experiment for each security add the present value of the first n elements of the cash flow and take the limit as n gets large this limit represents the fundamental value of the security the difference if any between the price of the security and its fundamental value is termed a speculative bubble this use of the terms fundamental and speculative bubble is we believe one of those that are generally accepted blanchard and fischer 1989 pp 218 221 for example used the terms precisely in this way yet confusion persists about what factors generate bubbles fads and irrationality have always figured prominently and the hypothesis that these factors are important has gained some empirical support from the literature on asset price volatility another bubbleproducing factor is the structure of information in the market in a partialequilibrium setting allen and gorton 1988 showed that rational bubbles can exist with a finite number of agents who have asymmetric information although fads and asymmetric information can undeniably produce bubbles here we focus exclusively on the phenomenon of speculative bubbles in general equilibrium models with optimizing agents rational expectations and symmetric information an important source of confusion we believe is that the term fundamental is used in connection with sunspot equilibria as well as bubble equilibria a sunspot equilibrium is one in which prices and allocations depend on irrelevant sunspots as well as exogenous variations in fundamentals preferences technology and endowments bubbles on this usage reflect the effect of extrinsic uncertainty on equilibrium prices and allocations this use of the term fundamental in connec

the impact of environmental regulations on industry productivity direct and indirect effects abstract the paper develops an approach to measuring the impact of environmental regulations on total factor productivity growth which is less restrictive than a simple growth accounting approach environmental regulations have a direct impact on productivity growth due to the diversion of resources toward required abatement capital there can be a further indirect effect however as conventional inputs and production processes are changed in response to requirements to purchase abatement capital we estimate this indirect effect using a flexible functional form cost function total factor productivity and the direct and indirect productivity effects of environmental regulations are presented for five polluting industries we find that the indirect effect can be either positive or negative and in all industries is energy using the net impact of environmental regulations on total factor productivity growth is fairly small given that these are the most polluting industries they account for about 10 30 of the productivity decline of the 1970s in these industries
