is the entropy law relevant to the economics of natural resource scarcity abstract nicholas georgescu roegen and herman daly have argued that the entropy law imposes an absolute resource scarcity which cannot be overcome with technological change exploration or substitution on the contrary this paper argues that their critique is fundamentally flawed the pessimistic scenario requires a concept of materials entropy which is highly problematic materials entropy cannot be defined independently of technology and it is impossible to aggregate over different types of materials to meaningfully talk about available versus unavailable matter in the aggregate failing a concept of materials entropy the critique fails since the earth is not closed with respect to energy

is neoclassical microeconomics formally valid an approach based on an analogy with equilibrium thermodynamics abstract the relation between thermodynamics and economics is a paramount issue in ecological economics two different levels can be distinguished when discussing it formal and substantive at the formal level a mathematical framework is used to describe both thermodynamic and economic systems at the substantive level thermodynamic laws are applied to economic processes in ecological economics there is a widespread claim that neoclassical economics has the same mathematical formulation as classical mechanics and is therefore fundamentally flawed because 1 utility does not obey a conservation law as energy does 2 an equilibrium theory cannot be used to study irreversible processes here we show that neoclassical economics is based on a wrong formulation of classical mechanics being in fact formally analogous to equilibrium thermodynamics the similarity between both formalisms namely that they are both cases of constrained optimisation is easily perceived when thermodynamics is looked upon using the tisza callen axiomatisation in this paper we take the formal analogy between equilibrium thermodynamics and economic systems far enough to answer the formal criticisms proving that the formalism of neoclassical economics has irreversibility embedded in it however the formal similarity between equilibrium thermodynamics and neoclassical microeconomics does not mean that economic models are in accordance with mass energy and entropy balance equations in fact neoclassical theory suffers from flaws in the substantive integration with thermodynamic laws as has already been fully demonstrated by valuable work done by ecological economists in this field

impact of energy price rises on costs a thermodynamic analysis abstract the standard of living in an industrialized country depends on the quantity of energy available and the efficiency with which it is utilized changes in the price of energy will for a time influence the choice of goods and services and so affect the world economy until the balance between prices for goods and energy is restored if we could control the economy during this time interval there is no reason why increases in energy prices should reduce our standard of living if renewable energy sources are to be more expensive than oil today by implication we need to invest much more capital to be able to utilize these sources we should therefore be willing to accept a smaller increase in standard of living and use the difference for investment in equipment to convert renewable energy sources to useful work only through new technology can the price of energy from such sources be reduced relative to the price of energy from oil increases in oil prices will not change the price ratio

energy as a factor of production and entropy as a pollution indicator in macroeconomic modelling abstract fluctuating energy prices and the environment s limited capacity for absorbing pollution constitute significant uncertainties for future industrial evolution solving a set of differential equations and using the simplex algorithm in linear programming we look into the questions how changing energy inputs and prices have affected industrial growth in the past and how the energy system can be optimized so that pollution becomes minimum in the future we obtain production functions which depend linearly on energy and exponentially on the ratios of labor capital and energy capital they describe well the growth of output in west germany and the u s a during the last two decades and the responses to theenergy price explosions energy conservation was an important response element the most optimistic possible savings of primary energy by heat exchangers heat pumps and cogeneration at the present fixed energy demand profiles are computed to be 54 in the netherlands 36 in west germany and 59 in japan a pollution indicator entropy production is proposed and incorporated in a model of enviromental constraints on industrial growth

explaining third world alignment many argue that balance of power theory is as applicable to the third world as it is to other states without substantial modification however balance of power theory cannot explain third world alignments because it ignores key characteristics of third world states that determine alignment the author develops a theory omnibalancing that is relevant to the third world and that repairs these defects rather than balance of power s emphasis on states seeking to resist threats from other states omnibalancing explains third world alignments as a consequence of leaders seeking to counter internal and external threats to their rule the superiority of omnibalancing over balance of power in making third world alignments understandable is related to the third world in general and to the alignment decisions of two key third world states in particular the author concludes by discussing why an understanding of the third world including third world alignment is central to the study of international relations

spot and forward volatility in foreign exchange this paper investigates the empirical relation between spot and forward implied volatility in foreign exchange we formulate and test the forward volatility unbiasedness hypothesis which is the volatility analogue to the extensively researched hypothesis of unbiasedness in forward exchange rates using a new data set of spot implied volatility quoted on over the counter currency options we compute the forward implied volatility that corresponds to the forward contract on future spot implied volatility known as a forward volatility agreement we nd statistically signi cant evidence that forward implied volatility is a systematically biased predictor that overestimates future spot implied volatility the bias in forward volatility generates high economic value to an investor exploiting predictability in the returns to volatility speculation and indicates the presence of predictable volatility term premiums in foreign exchange

the institutional roots of american trade policy politics coalitions and international trade the 1934 reciprocal trade agreements act rtaa changed the structure of the making of u s trade policy and made possible a dramatic reduction in tariffs the authors demonstrate that the key institutional innovation in the rtaa was its mandate to lower tariffs through reciprocal agreements with foreign nations the expansion of exports under the rtaa enhanced political support for increasingly lower u s tariffs evidence that export interests were positively associated with congressional votes for free trade supports this view

a reexamination of the role of thermodynamics for environmental economics abstract as the discussion about the role of thermodynamics in environmental economics has not led to a conclusion yet a more fundamental approach seems to be necessary which also takes into consideration the relationship between economics and the natural sciences in general to this end value theory is chosen as a starting point because it is the centerpiece of every economic theory it is shown that neoclassical environmental economics suffers from serious deficiencies because of its value concept heedlessly copied from classical mechanics thermodynamics can be expected to be helpful to redress these defects because the economy can be thought of as a dissipative structure dependent on its environment the obvious way to integrate thermodynamics consists in the formulation of thermodynamic constraints to complement neoclassical environmental economics but this approach remains unsatisfactory because the neoclassical mechanical hardcore is incompatible with the entropy law and its implications evidently the neoclassical paradigm and its value concept have to be given up but the alternative of the energy theory of value must be rejected because its determinism cannot be reconciled with the richness of human behaviour as thermodynamic analogies offer no solution either there is a dilemma between the necessity and the apparent impossibility of adequately integrating thermodynamic concepts it turns out that a normative inconsistency is responsible which is due to the demand for intergenerational justice therefore the integration of thermodynamics into environmental economics hinges on a meta economic value decision if sustainability is adopted as the guiding principle the insights of thermodynamics call for a macro economic environmental policy setting absolute limits to the economy but this macro policy is incompatible with neoclassical economics so that a social reconstruction of economics based on a social theory of value becomes necessary in sum thermodynamics is important for environmental economics besides fulfilling a general heuristic function it also fulfils a decisive conceptual and an analytical function insofar as it helps to justify sustainability and to operationalize macro economic environmental policy

challenges and prospects of valuation cruise ship pollution case negative externalities and natural resource valuations play an important role in the debate and analysis of sustainable development however as yet they have not been included extensively in tourism research or planning as a result limited progress has been made to improve environmental management and address resource management challenges this paper seeks to stimulate the discussion over the advantages disadvantages failures and successes of selected economic and development discourses valuation methodologies are discussed and placed within a pollution valuation impact model to identify opportunities to assess the impact of pollution and the value of natural capital in the tourism context cruise tourism is used to demonstrate the model due to its rapid growth and the potential for intense pollution outputs it is considered in the context of a developing and transition state one which sees tourism as a panacea to the problem of accessing international currency by employing cross disciplinary research and applying valuation logic the paper aims to contribute to the decision making process in tourism

exploring futures for amazonia s sierra del divisor an environmental valuation triadics approach to analyzing ecological economic decision choices in the context of major shifts in boundary conditions abstract this text presents a new methodological approach to ecological economic analysis employing georgescu roegen s flow fund theory of economic process it offers an alternative to monetary valuation based analyses and aims to contribute toward advancing work concerned with addressing complex ecological economic questions as complete wholes the methodology is demonstrated through reference to the empirical case of a proposed rail link between peru and brazil which would cut across the sierra del divisor of western amazonia connecting the pacific and atlantic coasts and further opening up the amazon commodity frontier in order to analyze the potential impacts of the rail link four flow fund representations of economic process two at the regional and two at the local level are developed in order to juxtapose two alternative political economy contexts that might govern the rail link s impacts in the region one where conservation is prioritized over cash income and one where it is not our results suggest that completion of the rail link under the current political economy context which prioritizes cash income over conservation is likely to have substantial negative consequences for forest conservation in both peru and brazil and for local livelihoods throughout the region

democratization and international organizations international organizations ios have become increasingly pervasive features of the global landscape while the implications of this development have been studied extensively relatively little research has examined the factors that prompt states to enter ios we argue that democratization is an especially potent impetus to io membership democratizing countries are likely to enter ios because leaders have difficulty credibly committing to sustain liberal reforms and the consolidation of democracy chief executives often have an incentive to solidify their position during democratic transitions by rolling back political liberalization entering an io can help leaders in transitional states credibly commit to carry out democratic reforms espe cially if the organization is composed primarily of democratic members tests of this hypothesis based on a new data set of ios covering the period from 1965 to 2000 confirm that democratization spurs states to join ios in recent years international organizations ios have become increasingly perva sive features of the global landscape both the number of such organizations and the range of issue areas they cover have grown rapidly the implications of this development have been studied extensively and hotly debated in the field of inter national relations whereas some researchers believe that ios have little effect on state behavior many observers argue that the proliferation of these institutions will facilitate interstate cooperation and help to resolve the interstate conflicts that do arise 1 in contrast relatively little research has been conducted on the factors that prompt states to enter ios this gap in the literature is both surprising and important while many countries have rushed to join ios others participate in few of these organizations what determines the propensity of states to join ios

on the life cycle metaphor where ecology and economics diverge abstract there is an attractive analogy between nature and industry based on the similarity of natural functions and certain industrial activities for instance animals ingest eat and digest food finally there are metabolic wastes firms are analogous to organisms in several respects insofar as they consume material resources process digest them and produce output products and excrete wastes firms like organisms also compete with each other for resources curiously enough one of the apparent differences between natural and man made systems is actually not one like the industrial system the natural system does not recycle everything however there are at least four real and important differences between the biosphere ecology and the technosphere economy first there is no primary producer in the economic system analogous to what photosynthesizers play in the biosphere inputs to the economy are mostly natural resources capital services and labor second in the economic system output is a heterogeneous mix of manufactured products and services labor in economics is an input but not an output the economic system recycles much less than the ecological system but utilizes a far greater suite of elements in the biosphere there are no products as such growth is tantamount to accumulation of embodied solar exergy in the form of cellulose sugars lipids and proteins the biosphere produces only wastes and more of itself plus dead matter third in the biosphere there are no markets there is no medium of exchange like money and there is nothing analogous to paid labor exchanges are involuntary i e by predation parasitism or theft fourth evolution in nature is driven by differentiation by random mutations of the genome and darwinian selection based on reproductive success in economics differentiation is based on discovery invention and innovation by intelligent economic agents and selection is based on competition at the individual or firm level either way the economic system is not closely analogous to an ecosystem attempts to use ecological concepts in an economic context are often misleading and unjustified the paper discusses the implications of the eco eco mismatch for resource accounting and life cycle analysis

is the entropy law relevant to the economics of natural resource scarcity comment abstract jeffrey t young s critique of the work of nicholas georgescu roegen and herman e daly questions the relevance of the entropy law for economic analysis and provides a concise faithful summary of the positions of georgescu roegen and daly along the way however young produces an alternative model of natural resource depletion that is based upon questionable interpretations of the laws of thermodynamics in particular young s claim that natural resource economics can be divided into conservation law orientations and entropy law orientations and his claim that the entropy law pertains to energy but not to matter seem unsupportable from a scientific view

capital energy substitution and the multi level ces production function abstract this paper has clarified a misconception in sato s multi level ces production function and used the function in testing for capital energy substitution in taiwanese manufacturing the empirical results show that capital and energy are substitutes and the aes estimates differ little from those derived from the translog approximation

an object oriented framework for valuing shout options on high performance computer architectures abstract a shout option is a financial contract which allows the holder to change the payoff during the lifetime of the contract complex versions of these options are embedded in financial products which offer various types of maturity guarantees such as segregated funds marketed by canadian insurance companies the value of these options can be determined by solving a collection of coupled partial differential equations in this work we develop an object oriented framework for valuing these contracts which is capable of exploiting modern high performance computer architectures we use this framework to study practical aspects of valuing and hedging these contracts

international human rights a regime analysis after laying out a typology of international regimes eight international and regional human rights regimes are analyzed in order to 1 examine the utility of regime analysis in noneconomic issue areas and 2 assess the nature extent and evolution of international cooperation on human rights there has been a remarkable growth of international action since 1945 when human rights were not even widely accepted as a legitimate issue area this growth can be explained largely by expanding perceptions of moral interdependence and community increased national commitment the growing ideological appeal of human rights and changes in the distributions of international power these same factors however suggest only limited future growth on a broader theoretical plane the case of human rights suggests a significant if limited and principally heuristic utility for regime analysis especially to the extent that international relations is becoming increasingly concerned with specific issues

pricing methods and hedging strategies for volatility derivatives abstract we explore the valuation and hedging of discretely observed volatility derivatives using three different models for the price of the underlying asset geometric brownian motion with constant volatility a local volatility surface and jump diffusion we begin by comparing the effects on valuation of variations in contract design such as the differences between specifying log returns or actual returns and incorporating caps on the level of realized volatility we then focus on the difficulties associated with hedging these products delta hedging strategies are ineffective for hedging volatility derivatives since they require very frequent rebalancing moreover they provide limited protection in the jump diffusion context we study the performance of a hedging strategy for volatility swaps that establishes small fixed positions in vanilla options at each volatility observation

concepts of efficiency in ecological economics sisyphus and the decision maker abstract efficiency forms the bedrock of policy planning and business approaches to sustainable development but what do ecological economists mean by efficiency in the resource use context efficiency has a wide range of potential interpretations from the ratio of work output energy inputs to pareto efficiency despite the potential richness of the efficiency concept in practice efficiency is often narrowly conceived within disciplinary boundaries this appears to be the case even in ecological economics which purports to be transdisciplinary and pluralistic such narrow disciplinary perspectives essentially waste the richness of the efficiency concept this wasting could mean ecological economists and decision makers are destined to sisyphean toil in the pursuit of sustainable development this paper explores the efficiency concept and its interpretation it then reviews ecological economic literature to find that there is much room for improvement in the way ecological economists apply efficiency finally the paper presents a framework within which a truly ecological economic approach to efficiency can emerge armed with this framework policy makers and planners should be better prepared to make decisions leading to sustainable development

the balance of power in the balance this article reviews four recent books on balancing and the balance of power both in isolation and when taken together they provide strong analytical and empirical warrants against the proposition that balance of power equilibria represent the normal condition or natural tendency of international relations they also reflect the growing dissensus among realists concerning how to conceptualize and operationalize the key concept of balancing the author argues that their analysis implies a tripartite distinction between balance of power theory theories of power balances and theories of balancing recognizing this distinction undermines many objections to expanding the concept of balancing to include nontraditional variants but it also helps elucidate why we should eschew describing nontraditional balancing through the language of hard and soft balancing even a more expansive conception of balancing however fails to insulate balance of power theory against mounting disconfirming evidence while one might be able to salvage a weak variant of balance of power theory realists are probably better off adopting a more nuanced and comprehensive approach to power political competition the entire field would benefit from treating balancing and the balance of power as objects of inquiry in their own right rather than as the province of realist theory

entropy and natural resource scarcity a reply to the critics abstract the paper reaffirms the author s view that entropy is not relevant to the economics of natural resource scarcity once system boundaries are carefully defined entropic considerations are either already incorporated into relative price information or represent such a long run constraint as to be irrelevant to foreseeable human welfare while matter and energy both undergo entropic dissipation it is argued there is an asymmetry in that energy can be imported to recycle matter but the converse importing matter to recycle energy is pure science fiction therefore an open system such as the earth can maintain any level of organization

international law and domestic institutions reconciling north american unfair trade laws while scholars have written much about the role played by international institutions in cooperative behavior among nations they have not examined the domestic political motives that may lie behind nations decisions to join such organizations two level games analysis provides a framework for studying domestic politics not as a constraint upon nations that enter into international agreements but as a catalyst for nations to enter into agreements the dispute settlement procedures of the north american free trade agreement and its predecessor the canada u s free trade agreement offer an empirical illustration of this point

toward consilience between biology and economics the contribution of ecological economics abstract during its ten year history ecological economics has made a real difference in the way economists look at the natural world and in the way biologists look at the economy in this survey article we examine the contributions to the journal in terms of e o wilson s concept of consilience that is his argument that the methods and assumptions of any field of study should be consistent with the known and accepted facts in other disciplines in particular we examine the contributions of ecological economics to reconciling the economic theory of the consumer and producer with biophysical reality

the hotelling rule for entropy constrained economic growth abstract lozada gabriel a 1995 xxx ecological economics the entropy change of the solar system between now and its final heat death is fixed the time to the heat death is determined by the rate of entropy increase between now and then if this rate of entropy increase is itself increased by economic activity then economic activity is generating a negative externality by internalizing this a social planner treats the fixed amount of entropy change remaining until the heat death like the stock of an exhaustible resource this leads to an analysis along the same lines as hotelling s neoclassical economics of exhaustible resources forming a partial synthesis between neoclassical economics and nicholas georgescu roegen s ecological economics work on the entropy law

from microscopic to macroscopic theories entropic aspects of ecological and economic processes abstract the paper discusses the relevance of thermodynamics and related theories to ecological economics it is argued that it is not useful to apply the entropy term directly to economic processes physical entropy terms defined on a microscopic level for isolated systems are quite far from economic and ecological reality only theories that deal with the development of open systems far from thermodynamics equilibrium provide the important link between entropy and evolution towards higher complexity major new impulses for ecological economics come especially from evolutionary ecological theories these quite recent theoretical approaches incorporate the knowledge of far from equilibrium thermodynamics and explain dynamic changes in ecosystems on a macroscopic level from a thermodynamic perspective thermodynamic approaches provide a heuristic base for the analysis of economy environment interactions important implications of these approaches concern time irreversibility ecological efficiency and the interdependencies of environmental problems and evolution

towards a centerpiece for ecological economics this paper offers a hypothesis with cognitive claims for a social theory that is relevant for ecological economics as background a fable has ego metaphorically viewed as a horse driven to problematic extremes with the solution becoming an integration and balance of means with the other horse empathy the ego n empathy hypothesis starting with a new root metaphor which is extended with a pre analytic vision the main support for the cognitive claims is with a mathematical model and a metaeconomic analysis armed with both scope and precision along with an assortment of corroborative evidence from different disciplines the paper provides support for establishing a new center cognitive claims have ego and empathy apart giving value and possibilities and together as ego empathy giving an emergent value possibility this possibility suggests a rallying point for transdisciplinary work and a theoretical centerpiece for ecological economics suited as such the economic ego of homo economicus is distinguished from the political ego of sacro egoismo corroboration with adam smith s moral philosophy political economy is highlighted the individual person of an empirical ethics stemming from both self interest and fellow feeling is resurrected to support the hypothesis awareness emerges like a complementary consciousness an added value strikingly similar to smith s impartial spectator empirical demonstration concludes this integration of interests with a metaeconomic analysis for the case of soil and water conservation policy in the north american farming population taken together the root metaphor with reasonable scope and precision corroboration and demonstration help to structure the ego n empathy hypothesis d 2004 elsevier b v all rights reserved

allocation distribution and scale towards an economics that is efficient just and sustainable abstract the practical policy of issuing tradeable permits for depletion and pollution requires for its implementation the clear separation of the three basic economic goals of efficient allocation equitable distribution and sustainable scale economic theory needs to catch up with policy in recognizing that scale issues cannot be reduced to either allocation or distribution

anarchy hierarchy and the variety of international relations security relations between states vary along a continuum from anarchic alliances to hierarchic empires this continuum in turn is defined by the parties rights of residual control the state s choice between alternatives is explained in a theory of relational contracting as a function of the expected costs of opportunism which decline with relational hierarchy and governance costs which rise with relational hierarchy a comparison of early postwar relations between the united states and western europe and the soviet union and eastern europe illustrates the theory

environmental constraints and sigmoid utility implications for value risk sensitivity and social status abstract friedman and savage journal of political economy 4 1948 279 proposed sigmoid utility theory to model the relationship between social class and risk sensitivity their proposal has not been explicitly modeled to allow for full testing of the concept we argue that sigmoid utility arises naturally from boundary conditions imposed by finite environmental resources that engender competition we also present a sigmoid formulation and examine its empirical warrant by considering economic data from anthropological historical and sociological cases studies standard risk sensitivity measures such as arrow pratt and downside risk aversion provide expectations for which individuals are most risk prone insights from prospect theory indicate under what conditions sigmoid utility may be most useful we consider the implications of environmental constraint in the context of the sigmoid model as an explanation for the nature of political turmoil during the collapse of maya civilization ca ad 850 we consider the role lack of constraint played in the american revolution and we explore how sigmoid utility can enrich our understanding of contemporary american voting behavior

economic arguments on the sufficiency of natural resources economics used to be a dismal science of gloomy predictions for the future of mankind but this has changed in recent times barring a few remarkable exceptions e g common and pearce 1973 georgescu roegen 1979 pearce 1975 most economists seem to be surprisingly united in what might appear to be an almost stultifying complacency bliss 1980 p ix according to this mood of buoyant optimism rosenberg 1980 p 108 the widespread anxiety about future resources is seriously mistaken because of severe over estimation of resource scarcity as well as severe underestimation of the efficiency of spontaneous market reactions beckerman 1972 boserup 1980 nordhaus 1973 1974 kay and mirrlees 1975 this agreement inside the profession is still more amazing if the main thesis of the fol lowing discussion is correct namely that economics particularly in the form of neoclassical economic theory is of practically no use for the evaluation of the sufficiency of natural resources of course economics in a more general sense is important for many other ques tions of resource policy but not for this one the economic arguments for the optimistic view of resource problems are classsified into three groups arguments based on the devel opment of resource prices historical arguments and market mechanism arguments this paper argues that they are all mistaken and that technological and political considerations not only cannot be ignored but are of overwhelming importance

domestic sources of alliances and alignments the case of egypt 1962 73 the theoretical and empirical literature on international alliances has tended to support the realist view that the pursuit or tightening of external alignments stems predominantly from external security threats consequently the role of domestic factors has generally been ignored or downplayed this article begins with the observation that leaders confronted with external threats make trade offs between the pursuit of external alignments and the mobilization of domestic resources it then argues that the choice of strategy depends on a combination of systemic and domestic factors including the perceived degree of external threat to state security the perceived degree of domestic instability and threat to the government and the constraints that derive from the domestic political economy the analysis of egypt s alignment behavior during the period from 1962 to 1973 underscores the impact of domestic and economic political constraints on the choice of domestic mobilization or alliance formation and the central role of alliances in providing resources for confronting domestic as well as foreign threats

a jump diffusion model for option pricing brownian motion and normal distribution have been widely used in the black scholes option pricing framework to model the return of assets however two puzzles emerge from many empirical investigations the leptokurtic feature that the return distribution of assets may have a higher peak and two asymmetric heavier tails than those of the normal distribution and an empirical phenomenon called volatility smile in option markets to incorporate both of them and to strike a balance between reality and tractability this paper proposes for the purpose of option pricing a double exponential jump diffusion model in particular the model is simple enough to produce analytical solutions for a variety of option pricing problems including call and put options interest rate derivatives and path dependent options equilibrium analysis and a psychological interpretation of the model are also presented

the origins of human rights regimes democratic delegation in postwar europe the e ftieth anniversary of the un universal declaration on human rights marks an appropriate moment to reconsider the reasons why governments construct international regimes to adjudicate and enforce human rights such regimes include those established under the european convention for the protection of human rights and fundamental freedoms echr the inter american convention on human rights and the un covenant on civil and political rights these arrangements differ from most other forms of institutionalizedinternational cooperation in both their ends and their means unlike international institutions governing trade monetary environmental or security policy international human rights institutions are not designed primarily to regulate policy externalities arising from societal interactions across borders but to hold governments accountable for purely internal activities in contrast to most international regimes moreover human rights regimes are not generally enforced by interstate action although most arrangements formally empower governments to challenge one another such challenges almost never occur the distinctiveness of such regimes lies instead in their empowerment of individual citizens to bring suit to challenge the domestic activities of their own government independent courts and commissions attached to such regimes often respond to such individual claimsby judging that the applicationof domestic rules or legislationviolates international commitments even where such legislationhas been

self organization and sustainability energetics of evolution and implications for ecological economics abstract in the 1920s alfred lotka suggested that evolution results both in an increasing total energy flow through the biosphere and in increasing energy efficiency of biological processes later authors attempted to generalize lotka s conjectures and to transform them into general evolutionary laws these laws are derived from the laws of thermodynamics and it is frequently argued that they also apply to the development of economic systems in the present paper an alternative interpretation of the lotka principles is suggested which starts from the self organization of dissipative structures self organization concepts from ecological and evolutionary economics are integrated on this basis energetic regularities in evolutionary processes are interpreted as emergent properties of competitive self organization given the close relationship between energy dissipation in economic processes and various environmental problems thermodynamic effects of economic evolution are of practical policy relevance the evolutionary perspective taken here implies that policy measures toward sustainable development will primarily have to affect the kinds of innovative behavior triggered in competitive processes

a thermodynamic approach to economics abstract the economic theory presented in this paper develops a theme first published by the author in energy economics 1 the concept that economic value is fundamentally equivalent to energy value both at a macro and micro level is investigated in some depth economic equivalents of the first and second laws of thermodynamics are derived and inflation is shown to be equivalent to net cycle entropy gain a simple business cycle is constructed from a number of basic economic processes and a series of efficiency measures are examined including overall efficiency work ratio net work output cycle inflation growth and stock turnover a model of the money system is developed and the effects of monetary policy are examined the difficulties of deriving a standard scale of productive content a necessary part of the valuation of economic goods and services are analysed it is hoped that the paper will open up new avenues for future work particularly of statistical investigations of macro and micro systems

protecting democracy in europe and the americas especially since the end of the cold war the council of europe ce and the organization of american states oas have acted to protect democracy in their member states from erosion or reversals with ce policies more robust than those in the americas what explains this variation i develop an argument focus ing on institutional permeability or the extent to which those organizations are acces sible to nonstate actors permeability consists of three dimensions range of third parties allowed access level of decision making at which access is granted and transparency of io information to those third parties higher levels of permeability are likely to produce higher levels of constraint on state behavior through increas ing levels of precision and obligation in international rules and practices alterna tive explanations summarized as regional democracy norms domestic democratic lock in interests and the power of stable democracies cannot explain the variation in multilateral democracy protection more broadly this article suggests that democratizing ios by allowing ever greater access to nonstate actors is likely to result in stronger more constraining international rules even in areas where states most jealously guard their sovereignty such as the nature of their domestic political institutions

an empirical comparison of continuous time models of implied volatility indices abstract we explore the ability of alternative popular continuous time diffusion and jump diffusion processes to capture the dynamics of implied volatility indices over time the performance of the various models is assessed under both econometric and financial metrics to this end data are employed from major european and american implied volatility indices and the rapidly growing cboe volatility futures market we find that the addition of jumps is necessary to capture the evolution of implied volatility indices under both metrics mean reversion is of second order importance though the results are consistent across the various metrics markets and construction methodologies

entropy law and exhaustion of natural resources is nicholas georgescu roegen s paradigm defensible abstract i examine whether the entropy law dictates absolute limits to growth i distinguish the entropy law proper diffusion without coherent work from its application the carnot cycle diffusion with coherent work while the entropy law pertains to mechanistic systems the carnot cycle is the result of purposeful agency since the economic process is carried out by purposeful agency to generate coherent work it is not governed by the entropy law rather it resembles the carnot cycle resources hence cannot be defined objectively a la the entropy law resources can only be defined relative to the purposeful agency thus the prognosticators of doom like georgescu roegen cannot be bolstered by the entropy law

option pricing and replication with transactions costs transactions costs invalidate the black scholes arbitrage argument for option pricing since continuous revision implies infinite trading discrete revision using black scholes deltas generates errors which are correlated with the market and do not approach zero with more frequent revision when transactions costs are included this paper develops a modified option replicating strategy which depends on the size of transactions costs and the frequency of revision hedging errors are uncorrelated with the market and approach zero with more frequent revision the technique permits calculation of the transactions costs of option replication and provides bounds on option prices

the economic growth debate what some economists have learned but many have not one thing economists should have learned from the economic growth debate is the importance of defining the term growth by growth i mean quantitative increase in the scale of the physical dimensions of the economy i e the rate of flow of matter and energy through the economy from the environment as raw material and back to the environment as waste and the stock of human bodies and artifacts by development i mean the qualitative improvement in the structure design and composition of physical stocks and flows that result from greater knowledge both of technique and of purpose simply put growth is quantitative increase in physical dimensions development is qualitative improvement in non physical characteristics an economy can therefore develop without growing just as the planet earth has developed evolved without growing neoclassical growth models notwithstanding there is good evidence that neither the earth s surface nor the flux of solar energy grows at a rate equal to the rate of interest in fact they seem not to grow at all yet qualitative evolution occurred and continues to occur two general classes of limits to growth in the above defined sense can be further distinguished biophysical limits and ethicosocial limits in both cases it is growth not development that is limited there may or may not exist limits to development but that is another topic standard neoclassical economics was built on the assumption that the economy is far from both limits i e that it is always biophysically possible and ethicosocially desirable for aggregate product to grow as abramowitz l put it echoing pigou

a general framework for discretely sampled realized variance derivatives in stochastic volatility models with jumps abstract after the recent financial crisis the market for volatility derivatives has expanded rapidly to meet the demand from investors risk managers and speculators seeking diversification of the volatility risk in this paper we develop a novel and efficient transform based method to price swaps and options related to discretely sampled realized variance under a general class of stochastic volatility models with jumps we utilize frame duality and density projection method combined with a novel continuous time markov chain ctmc weak approximation scheme of the underlying variance process contracts considered include discrete variance swaps discrete variance options and discrete volatility options models considered include several popular stochastic volatility models with a general jump size distribution heston scott hull white stein stein hypergeometric 3 2 and 4 2 models our framework encompasses and extends the current literature on discretely sampled volatility derivatives and provides highly efficient and accurate valuation methods numerical experiments confirm our findings

the second law the fourth law recycling and limits to growth abstract despite counter examples in nature it has been argued that total recycling is impossible for an industrial society as a consequence of the second law of thermodynamics in this paper it is shown that there is no such limitation however it is also shown that there must be a large stockpile of inactive materials as well as an exogenous source of exergy e g from the sun for a stable steady state recycling system to function the paper also discusses briefly some of the implications for economic growth

entropy structure and organisational change abstract the paper sets out a basis for rigorous thermodynamic characterisation of structural change and of organisational interdependencies between economic and environmental processes many attempts have been made to exploit entropy as a generic explanatory variable it has widely been proposed that entropy is a measure of the level of dis order of a system of how mixed up things are then as organisation is often thought synonymous with some notion of order it has been a small step to propose that increasing organisation is the converse of increasing entropy another suggestion has been that social system structure and change can be explained in terms of a tendency towards maximum entropy production the lotka principle of maximum energy dissipation all these notions must be rejected the putative entropy order connection has its inspiration in boltzmann s probabilistic interpretation of thermodynamic entropy as a measure of microscopic disorder this order principle is simply not applicable under conditions far from thermodynamic equilibrium prigogine conditions which prevail for all important economic and ecological processes under such conditions the relationship between entropy production and changes in structure or organisation is multi faceted and situation specific attempts to account for the specificity of societal activities in terms of a generic scalar measure of organisation or dissipation are largely after the fact and in no way do away with the need for analysis of institutional and ethical dimensions of human action in their own right when properly allied to institutional analysis however the far from equilibrium thermodynamics furnishes a rich impetus for a coevolutionary perspective in ecological economics with promise of incisive treatments of in particular issues of system environment codependency and of the time in determinacies of economy environmental change

environmental economics and ecological economics where they can converge abstract environmental economics and ecological economics share the common objective of understanding the human economy environment interaction in order to redirect the economies towards sustainability in pursuing this objective these two perspectives utilise different types of analytical framework and are opposed to each other on many of the fundamental theoretical and methodological issues while the environmental economics has progressed within a narrowly but sharply focused neoclassical analytical approach the ecological economics has expanded by adopting a diversified approach which led to widen the gap between the two this article makes an attempt to highlight the divergence between these two perspectives on different issues and identifies certain research avenues that would potentially bring convergence between these two perspectives
