asset specificity and the fear of exploitation if asset specificity renders the investing party dependent ex post why would the ex ante willingness to make relationship specific investments vary we show how specific investments generate both positive and counter negative cooperative incentives we also observe the influences of trust and time horizon on these incentives which are aggregated to derive the specific investments effect sie our result suggests that while the fear of exploitation increases proportionally to the magnitude of specific investments and the attendant quasi rents it grows exponentially with the deterioration of inter personal trust and or inter temporal time horizon contexts

a multi regional input output analysis of the pollution haven hypothesis from the perspective of global production fragmentation pollution haven hypothesis is an important debate on the environmental effects of international trade the pattern of which has been reshaped obviously by global production fragmentation recently the production process is distributed globally and the pollution haven effect of international trade is becoming more complicated for instance intermediate product trade corresponds to the largest share of embodied emissions and the share of emissions induced by the global value chain related trade is increasing gradually the aim of this paper is to make a comprehensive analysis on the pollution haven hypothesis in carbon emissions embodied in three different trade patterns from global bilateral and national perspectives we propose a method to parcel the pollution haven hypothesis in a multi regional input output analysis and discuss the contribution of production fragmentation for global emissions it is found that international production fragmentation generates global emissions savings the intermediate product trade has a negative balance of avoided emissions the final product trade becomes increasingly less environmentally effective during the period 1995 2009 there are significant differences in the environmental effects of different trade patterns for each country

competition cooperation and innovation organizational arrangements for regimes of rapid technological progress abstract discussions of the link between firm size and innovation are outmoded because the boundaries of the firm have become fuzzy in recent decades strategic alliances constellations of bilateral agreements among firms are increasingly necessary to support innovative activities such alliances can facilitate complex coordination beyond what the price system can accomplish while avoiding the dysfunctional properties sometimes associated with hierarchy antitrust law and competition policy need to recognize that these new organizational forms are often the functional antithesis of cartels though they may have certain structural similarities a more complete understanding of bilateral contracts and agreements ought to reveal when and how cooperation can support rather than impede innovation and competition

examining the global environmental impact of regional consumption activities part 2 review of input output models for the assessment of environmental impacts embodied in trade this paper offers a detailed review of recently described single and multi region input output models used to assess environmental impacts of internationally traded goods and services it is the second part of a two part contribution in part 1 turner k lenzen m wiedmann t and barrett j in press examining the global environmental impact of regional consumption activities part 1 a technical note on combining input output and ecological footprint analysis ecological economics we describe how to enumerate the resource and pollution content of inter regional and inter national trade flows with the aim to illustrate an ideal accounting and modelling framework for the estimation of ecological footprints a large number of such environment economic models have been described but only in the last few years models have emerged that use a more sophisticated multi region multi sector input output framework this has been made possible through improvements in data availability and quality as well as computability we identify six major models that employ multi sector multi region input output analysis in order to calculate environmental impacts embodied in international trade results from the reviewed studies demonstrate that it is important to explicitly consider the production recipe land and energy use as well as emissions in a multi region multi sector and multi directional trade model with global coverage and detailed sector disaggregation only then reliable figures for indicators of impacts embodied in trade such as the ecological footprint can be derived

international comparisons of domestic energy consumption abstract governments of many industrialized countries have committed themselves to substantially reduce their domestic emissions of greenhouse gases emission reductions can be achieved through technology and or sector specific policies to decide which part of the economy environmental policy should be concentrated at insight must be gained into the relative importance of the various factors determining domestic aggregate fossil fuel consumption by applying structural decomposition analysis sda across nations the factors causing per capita energy use to differ between countries can be identified which sheds light on where potential energy saving options can be found to demonstrate the usefulness of between country sda we apply the technique to a set of 8 oecd countries

an analysis of the driving forces of co2 emissions embodied in japan china trade abstract by using the latest china japan input output data sets and the index decomposition analysis ida approach this article analyzes the driving forces of co2 emissions embodied in trade between the two countries during 1990 2000 we found that the growth of trade volume had a large influence on the increase of co2 emissions embodiments in bilateral trade the dramatic decline in carbon intensity of the chinese economy is a primary cause in offsetting co2 emissions exported from china to japan over 1995 2000 we argue that a better understanding of the factors affecting co2 emissions embodied in international trade will assist in seeking more effective climate policies with wider participation in the post kyoto regime

responsibility and trade emission balances an evaluation of approaches this paper compares two concepts to evaluate the international responsibility of a country with respect to its emissions using a multi regional input output model we show that the trade emission balance and the responsibility emission balance yield the same result in practical work however a lack of data availability implies that the same technology assumption has been commonly adopted in that case also a third alternative exists which simply evaluates the emissions embodied in the trade balance of the country this third alternative yields the same results as the other two approaches at the aggregate level at the level of individual products however the results are clearly different and it turns out that the third alternative answers a different question that is it is appropriate for measuring the emission content of the products that cross the border in our empirical application we consider spain in 1995 and 2000 distinguishing nine different gases co 2 ch 4 n 2 o sf 6 hfcs pfcs so 2 nox and nh 3 c 2010 elsevier b v all rights reserved

reputation and the allocation of ownership we show that allocation of ownership matters even in a long term relationship where problems of opportunism are less severe unless agents are very patient ownership structure is chosen to give the agents best incentives to cooperate the optimal control structure of the static game restricts the gain from deviation to be the lowest but also the punishment will be minimal the worst ownership structure of the one shot game is good in the repeated setting because it provides the highest punishment but bad because the gain from deviation is also highest we show that when investment costs are very elastic partnership and a hostage type solution arise in equilibrium while when costs are moderately elastic the results of the one shot game apply

trends in the development of ecological economics from the late 1980s to the early 2000s abstract as the contributions to ecological economics are very diverse recent years have seen some discussion on both how to delimit the field and in which direction it should develop the intention with this paper is to contribute to the discussion by outlining important trends in the development of the field from the late 1980s to the early 2000s the study is inspired by other studies in the sociology and history of science in particular by the theoretical framework regarding scientific fields as reputational organizations which draws attention to both cognitive and social aspects of the formation of a field the basis for the paper is a combination of literature studies interviews with key researchers in the field and participant observations the paper outlines the characteristic cognitive features of ecological economics at the time of the birth of the field it is then described how the development in ecological economics was influenced by broader social factors during the following years and how the field was shaped by the inflow and outflow of different groups of researchers the emergence of different research programmes is outlined as is the organizational development finally the characteristics of ecological economics are summarized and the future prospects are briefly assessed

non contractible investments and vertical integration in the mexican footwear industry abstract this paper examines patterns of integration among manufacturers and retailers using data from a survey of footwear manufacturers in mexico the property rights framework developed in papers by grossman and hart 1986 j polit econ 94 691 and hart and moore 1990 j polit econ 98 1119 is differentiated from the standard empirical transactions cost framework in the context of this industry the most relevant distinction between the two frameworks is that the property rights framework addresses both the benefits and costs of integration while the transactions cost framework focuses only on variation in the benefits of integration we show that the costs of integration are highest where the retailer s non contractible investment has an important effect on the overall profits from the relationship consistent with the property rights framework the data suggest that integration is less likely in these circumstances

relational contracts and the theory of the firm relational contracts informal agreements sustained by the value of future relationships are prevalent within and between firms we develop repeated game models showing why and how relational contracts within firms vertical integration differ from those between nonintegration we show that integration affects the parties temptations to renege on a given relational contract and hence affects the best relational contract the parties can sustain in this sense the integration decision can be an instrument in the service of the parties relationship our approach also has implications for joint ventures alliances and networks and for the role of management within and between firms

a structural decomposition analysis of the emissions embodied in trade abstract the aim of this study is to quantify the driving forces behind the growth of carbon dioxide emissions embodied in trade eet the world input output database is used to estimate eet in 40 countries during 1995 2007 after which a structural decomposition analysis is applied to avoid biases in the results we have used the input output tables in previous year s prices and chained the outcomes in many developed countries the growth of emissions embodied in imports is much higher than the growth of emissions embodied in exports a key reason for this finding is the change in the structure of trade both in intermediate and in final products emerging economies like the bric countries have increased their share in production and trade at the expense of developed countries producers and consumers in developed countries have shifted towards importing a larger share of products from emerging countries this is the distinguishing feature that led to an increase of emissions embodied in imports for developed countries and an increase of emissions embodied in exports for emerging countries these results suggest policy makers to monitor eet more carefully and take the effects of trade on emissions into consideration

a review of recent multi region input output models used for consumption based emission and resource accounting abstract the interest in consumption based emission and resource accounting has grown significantly many studies juxtapose consumer emissions carbon footprint and producer territorial emissions of greenhouse gases in order to demonstrate the effects of trade on the national emission budget to this end a respectable number of studies have been undertaken worldwide in order to estimate emissions embedded in international trade of numerous countries and world regions input output approaches and increasingly multi region input output mrio models are commonly chosen as they provide an appropriate methodological framework for complete carbon footprint estimates at the national and supra national level with increasing processing capabilities of computers and a wider availability of economic accounts environmental accounts and trade data such models are now being implemented on a wide scale after a brief overview of salient single region input output studies i provide an in depth review of the most recent multi region input output models used for the purpose of consumption based environmental accounting the main methodological features and important results are described for around twenty studies covering the years 2007 to 2009 this is followed by a detailed review of studies dealing with uncertainty in mrio analysis an area which has not received a lot of attention so far i conclude that further research is mainly needed in two areas a improvements in data availability and quality and b improvements in the accuracy of mrio modelling

comparing structural decomposition analysis and index to analyze and understand historical changes in economic environmental employment or other socio economic indicators it is useful to assess the driving forces or determinants that underlie these changes two techniques for decomposing indicator changes at the sector level are structural decomposition analysis sda and index decomposition analysis ida for example sda and ida have been used to analyze changes in indicators such as energy use co2 emissions labor demand and value added the changes in these variables are decomposed into determinants such as technological demand and structural effects sda uses information from input output tables while ida uses aggregate data at the sector level the two methods have developed quite independently which has resulted in each method being characterized by specific unique techniques and approaches this paper has three aims first the similarities and differences between the two approaches are summarized second the possibility of transferring specific techniques and indices is explored finally a numerical example is used to illustrate differences between the two approaches

contracting with repeated moral hazard and private evaluations a repeated moral hazard setting in which the principal privately observes the agent s output is studied the optimal contract for a finite horizon is characterized and shown to require burning of resources these are only burnt after the worst possible realization sequence and the amount is independent of both the length of the horizon and the discount factor for the infinite horizon it is shown that there is no loss from restricting the analysis to contracts in which the agent receives a constant efficiency wage and no feedback until he is fired furthermore optimal contracts cannot be replicated by short term contracts a family of fixed interval review contracts is characterized longer review intervals are preferable but harder to implement comparative statics on the review length are carried out finally these contracts are shown approximate first best if players are very patient jel d82 d86

comparison of energy intensities in european union countries results of a structural decomposition analysis abstract this work proposes an input output structural decomposition analysis model to identify the sources of the differences in the energetic intensities of the european union countries given an economic structure a determined composition of the final demand and determined direct energy intensities by countries the work studies to what extent these factors explain the difference in aggregate energy intensities that are observed for different european union countries on the basis of this information indicators are constructed by sectors and countries that allow us to identify the role that each sector or country plays as an energy consumer the results show that the aggregate total energy differences in europe are strongly influenced by the direct energy intensity effect and by the demand effect without the different economic structures of the countries being an important factor in the explanation of these differences the metallurgical and manufacturing products sectors are identified as the most intensive in the aggregate energy intensity

the global co2 emissions growth after international crisis and the role of international trade in this paper we decompose the driving forces of global co2 emissions for the post crisis era 2008 2011 from both production based and consumption based aspects the results suggest that non oecd economies have become the major drivers for the rapid global growth of co2 emissions after the crisis more specifically the increasing consumption and investment of non oecd economies as well as stagnation of their emission intensity reductions have largely contributed to global growth of co2 emissions after 2009 on the contrary oecd economies have a less carbon intensive life style coupled with a decrease in investment and stagnation of consumption the oecd economies have successfully reduced both their production based and consumption based emissions however the magnitude of their reduction is much lower than the increase led by non oecd economies in addition both oecd and non oecd economies have started to increase their purchases of intermediate and final products from non oecd economies such changes of international trade caused an additional 673 mt of global emissions from 2008 to 2011 the results of our decomposition provide both worries about and insights into future global climate change mitigation

trade off analysis between embodied energy exports and employment creation in china moving towards sustainable consumption in china must factor in the drivers of production china s domestic energy demand is affected not only by domestic demand but also by foreign trade the accounting of energy embodied in china s international trade has attracted much attention in recent years in fact embodied energy imports exports are a part of the normal pattern of economic phenomena occurring through international trade with exports of embodied energy contributing significantly to china s economic development this research suggest that china s net embodied energy exports remained relatively stable before 2002 and then increased dramatically from 73 mtoe in 2002 to 502 mtoe by 2007 with an average annual growth rate of 47 2 over that period the total employment creation reliant on these exports is 191 3 million people including direct employment of 44 1 million people and indirect employment of 147 2 million people in 2007 and the total employment creation increased quickly between 2002 and 2007 with an average annual growth rate of 9 1 the share of employment created by exports in china s total employment increased from 16 5 in 1997 to 18 6 in 2002 and a more dramatic increase can be observed in 2007 of 28 1 the exports oriented sectors in china are energy intensive from the perspective of embodied energy consumption and the energy intensive exports are located in nearly the same sectors as the labor intensive exports china will find it difficult to sustain the trade off in costs due to unemployment if it wishes to reduce embodied energy exports china needs to exercise patience and long term reform to change the current development model because of its large economy and population base

why reputation favors joint ventures over vertical and horizontal integration a simple model abstract this paper investigates the effect of reputation in a model where two parties make noncontractable contributions to an economic undertaking it is shown that the optimal allocation of ownership between the parties is more similar in a repeated than in a one shot version of the model this implies that unified ownership and reputation are substitutes low discount rates and repeated investment decisions thus favor subcontracting and joint venture arrangements of the type commonly observed in japanese industry while full integration is more likely to be optimal when reputational forces are weak

new foundations for ecological economics abstract ecological economics has been repeatedly described as transdiciplinary and open to including everything from positivism to relativism i argue for a revision and rejection of this position in favour of realism and reasoned critique looking into the ontological presuppositions and considering an epistemology appropriate for ecological economics to meaningfully exist requires rejecting the form of methodological pluralism which has been advocated since the start of this journal this means being clear about the differences in our worldview or paradigm from others and being aware of the substantive failures of orthodox economics in addressing reality this paper argues for a fundamental review of the basis upon which ecological economics has been founded and in so doing seeks improved clarity as to the competing and complementary epistemologies and methodologies in part this requires establishing serious interdisciplinary research to replace superficial transdisciplinary rhetoric the argument places the future of ecological economics firmly amongst heterodox economic schools of thought and in ideological opposition to those supporting the existing institutional structures perpetuating a false reality of the world s social environmental and economic systems and their operation

measuring structural change and energy use decomposition of the us economy from 1997 to 2002 abstract the steadily increasing focus on energy production and consumption has led to growing research attention to patterns of energy use within economies of particular interest has been comparing the driving forces of increasing efficiency and economic structural change input output analysis ioa and decomposition analysis have become critical tools for performing such analyses this study analyzes aggregate energy use in the united states in 1997 and 2002 to discover the causes of changing energy usage and flows results show that rising population and household consumption acted to drive up energy demand but this driving force was offset by considerable structural change within the economy particularly related to a quickly increasing trade deficit in manufacturing goods thus while total energy intensity the ratio of energy use to economic output declined by approximately 12 between 1997 and 2002 changes in the structure of the economy explain this drop more than increased energy efficiency the level of aggregation at which decomposition analyses are run was identified as a crucially sensitive parameter for the determination of structural change and future studies should specifically address the amount of detail necessary to adequately measure changes in economic structure

co2 emissions per value added in exports of china a comparison with usa based on generalized logarithmic mean divisia index decomposition abstract this study first analyzes co 2 emissions per value added epv in exports of china during 1995 2009 and compares it with that of usa second a generalized logarithmic mean divisia index glmdi method is proposed to decompose the epv gaps between china and usa into five effects this method generalizes existing lmdi methods and makes the multiplicative decomposition of a sum of several terms possible then attribution analysis on value added coefficient effect is conducted results show that aggregate epv of china s exports is 4 20 mt billion us dollars in 1995 which decreases to 2 48 in 2009 for usa it is 0 66 0 33 respectively epv of china s exports is several times greater than that of usa at sectoral level industrial sectors and transport sectors are top sectors with large epv in china s exports which corresponds to the case of usa epv gaps of the service sectors between china and usa have become increasingly prominent since 2000 decomposition results show that emission coefficients value added coefficients and input output structure are the main driving factors of the expanding epv gaps between china and usa attribution analysis on value added coefficient effect the fastest growing effect shows that electrical and optical sector has been the largest contributor to epv gaps between china and usa resulting from value added coefficient effect since 1998 and its effect sharply increases during 1995 2009 policy implications derived are finally discussed

on the feasibility of maximal collusion abstract this note explores when joint profit maximizing behavior between firms can be supported by arbitrary subgame perfect equilibrium strategies we show that for a large class of games maximal collusion is feasible if and only if a simple discount parameter condition is satisfied

asset specificity and vertical integration asset specificity is usually considered to be an argument for vertical integration the main idea is that specificity induces opportunistic behavior and that vertical integration reduces the cost of preventing opportunism in this paper i show that asset specificity can be an argument for non integration in a repeated game model of self enforcing relational contracts it is shown that when parties are non integrated increasing degrees of asset specificity make it possible to design relational contracts with higher powered incentives

moral development of the economic actor abstract in this article we argue that the changes in moral content in economics can be explained as an evolution in accordance with the maturing process presented in kohlberg s stages of moral development firstly we describe and discuss the three levels of moral progress pre conventional conventional and post conventional as presented in kohlberg s theory secondly we draw a distinction between classical economics neoclassical economics and ecological economics and discuss to what extent the differences in ethics within the three theories can be explained by referring to the ethical development characterizing kohlberg s moral stages thirdly we discuss some of the hallmarks characterizing economics based upon what kohlberg termed universal principles at the highest stage in the development of moral reasoning to exemplify the evolution of moral reasoning in different economic theories we describe the changes that take place in the image of man over the last 2 300 years the human being in economics has been discussed in this journal with reference to three different relations to himself community and nature we have used the metaphors economic man social man and ecological man to characterize the ethical content of the three first stages at the first stage economic man interpreted as an egocentric individual seeking personal gain characterizes classical economics at the second stage social man seeks the best for a group of people within the perspective of neoclassical economics at the third stage ecological man is aware of the interrelatedness between economy and nature within ecological economics the agent is termed ecological man to indicate the interconnectedness between economy and the ecosystems while being aware of the weakness in predictive power inherent in these kinds of stage theories we find it stimulating to conclude with a description of economics based upon the ideas characterizing the highest level stage 7 in kohlberg s theory we put forward a hypothesis concerning a fourth stage in the development of economics termed neo ecological economics we describe the economic actor as cosmic man cosmic man has an extended self and incorporates all the other images of man

why does hov fail the role of technological differences within the ec abstract this paper examines the role of international differences in production techniques in explaining the empirical failure of the heckscher ohlin vanek hov model it develops a modified hov model that relaxes the assumption of identical production techniques across countries and can be estimated using input output data of individual countries the contribution of international differences in techniques to net factor trade patterns is then isolated by comparing the performance of the strict and modified hov models the paper finds that allowing for international technique differences significantly improves the predictive power of the hov model

temporal change of china s pollution terms of trade and its determinants abstract based on the world input output database wiod this study employed a revised pollution terms of trade ptt indicator to investigate the temporal change of china s environmental cost relative to its economic gains from international trade from 1995 to 2009 the results show that china has ptt larger than 1 indicating that china emits more emissions to obtain each unit of value added from exports than its trade partners over the period china s ptt first decreased from 1995 to 2001 and then increased from 2001 to 2009 the further decompositions show that improving technology is the leading driving force to decrease ptt while the change in global trade pattern is the leading force increasing ptt especially after 2001 we further decomposed the temporal change of china s ptt by income group of the trading partners the results show that the change in the global trade pattern is the crucial driving force behind the different changes of ptt by income group

a quantitative model for environmentally sustainable supply chain performance measurement abstract the development of robust mechanisms for supply chain performance measurement have been identified as an integral step needed for the transition towards sustainable supply chain systems and a greener global economy however measuring the environmental performance of supply chains is a challenging task due to several factors such as the lack of standardised methodologies and the inherent multi criteria nature of the problem by leveraging the capability of a multi regional input output framework to handle the complex and global nature of supply chains the current work presents a robust environmental sustainable performance measurement model underpinned by industrial lifecycle thinking as a result some theoretical insights are provided and an empirical application of the model to the metal products industry of the brics brazil russia india china and south africa nations undertaken in an attempt to address some of the methodological and applied measurement challenges in particular this allowed the modelling of carbon emissions trends within and between the brics nations and with the rest of the world over a 20 year period 1992 2011 as well as providing an opportunity to hypothesis on their future carbon emissions performances specific analyses of the metal product industry showed that demand represents the main driver for the increasing carbon footprint however the overall decline in reported carbon footprint was due to improvements in emissions intensity and efficiency gains induced by technology the study further assesses the effects of imports and economic growth on carbon footprint and discusses the implications of the study to sustainability transition processes in the brics nations

microeconomic degrowth the case of community supported agriculture in this paper we attempt to build a new microeconomic approach that could be considered as a basis of the degrowth macroeconomic view as degrowth is a critique of the dominant macroeconomic model of the endless search for economic growth its microeconomic foundations can be built by searching a relevant grass root economic initiative to theorise our approach is based upon the case study research of a self harvesting community supported agriculture in belgium the mainstream microeconomic model is based on the well known homo economicus assumption of individual self interest and competitive behaviour by contrast our model is based on a holistic approach of producers and consumers based upon trust cooperation and ecologically responsible behaviours this contribution participates to the flourishing literature on degrowth in ecological economics we begin by reviewing the debate on degrowth and economic behaviour we discuss the case study and its accounting expression that departs from the capitalist profit seeking model we conclude by explaining the limits and challenges of our model that implements degrowth on a small scale and in a capitalist environment

k william kapp s theory of social costs a luhmannian interpretation in developing his famous theory of social costs k william kapp claimed to draw inspiration from the theory of open systems the present paper reconstructs the notion of social costs from the perspective of the luhmannian theory of autopoietic social systems an alternative systems theoretic paradigm according to luhmann these systems build up their internal complexity at the cost of lowering their sensitivity to the complexity of their environment both societal and ecological from the luhmannian perspective social costs can be understood as those segments of environmental feedback that are thus ignored by social systems this perspective is not only consistent with kapp s own vision of social costs as a systematic outcome of private business enterprise but also even more radical as it traces these costs back to the regime of functional differentiation of society and thus to human civilization generally it follows from the luhmannian perspective that social costs can be reduced by improving the coordination between the individual functional systems such as economy law politics and science

carbon dioxide emissions in the u s economy a structural decomposition analysis this paper provides an empirical analysis of the impact of various influences on carbon dioxide emissions it incorporates methodological refinements of input output structural decomposition analysis which is the examination of economic change by means of a set of comparative static variations in key parameters of i o tables the analysis is performed using a two tiered klem model which allows for estimation of substitution and technological change effects within and between input aggregates the model is used to decompose the sources of change in co2 emissions in the u s over the 1972 82 timeframe using hybrid energy value tables for the initial and terminal years results show the significant effect of substitution within the energy sector and between energy and other inputs as the leading causes of the decline in carbon dioxide emissions

quo vadis mrio methodological data and institutional requirements for multi region input output analysis abstract in order to understand wider sustainability impacts of consumption and to successfully promote and implement sustainable consumption and production policies there is a need to capture the whole life cycle impact of products and services across international supply chains multi region input output mrio databases are a well described and suitable foundation for global sustainability analyses addressing a wide range of policy and research questions in this paper we reflect on the reasons for the recent boom in mrio compilation summarise the current state of development and discuss future options for mrio analysis we list in detail the requirements for efficient and effective mrio research and propose systemic and institutional changes we deliberately try to go beyond existing ambitions for mrio compilation and thus intend to stimulate discussion and to lay out the options for the future of mrio research

relational incentives and moral hazard in teams this paper studies moral hazard in teams using a model where efforts are promoted via the combination of profit shares and relational contracts the focus is on how these two forms of incentives interact according to the degree of effort observability and the importance of future interaction the optimal allocation of profit shares can range from a wide dispersion across players to a full concentration of shares in the hands of a single player when shares are sufficiently concentrated the corresponding residual claimant can also adopt the role of administering all relational contracts therefore serving as an endogenously chosen principal copyright 2007 wiley blackwell

governance of adjustments the article proposes a research program to compare game forms in terms of their ability to govern ex post adjustments to ex ante contracts the comparisons can be based on direct implementation costs or the extent to which desirable adjustments are not implemented in several examples of the program i compare three game forms negotiation over each adjustment ex ante price lists and implicit contracts leaving the stipulation of adjustments to one player if the latter game form is defined as an employment relationship the theory of the firm becomes a special case of the program the article starts with a discussion of the nature and magnitude of adjustment costs followed by an exposition of four examples i then discuss the role of asset ownership review some empirical evidence and look at broader implications

co2 emissions embodied in china us trade input output analysis based on the emergy dollar ratio to gain insight into changes in co2 emissions embodied in china us trade an input output analysis based on the emergy dollar ratio edr is used to estimate embodied co2 emissions a structural decomposition analysis sda is employed to analyze the driving factors for changes in co2 emissions embodied in china s exports to the us during 2002 2007 the results of the input output analysis show that net export of co2 emissions increased quickly from 2002 to 2005 but decreased from 2005 to 2007 these trends are due to a reduction in total co2 emission intensity a decrease in the exchange rate and small imports of embodied co2 emissions the results of the sda demonstrate that total export volume was the largest driving factor for the increase in embodied co2 emissions during 2002 2007 followed by intermediate input structure direct co2 emissions intensity had a negative effect on changes in embodied co2 emissions the results suggest that china should establish a framework for allocating emission responsibilities enhance energy efficiency and improve intermediate input structure

investing in a relationship a principal can make an investment anticipating a repeated relationship with an agent but the agent may appropriate the returns through ex post bargaining i study how this holdup problem and efficiency depend on the contracting environment when investment returns are observable informal contracts ex post can be more efficient than formal contracts as they induce higher investment ex ante the principal invests not only to generate direct returns but also to improve relational incentives unobservability of returns increases the principal s ability to appropriate the returns but reduces her ability to improve incentives the optimal information structure depends on bargaining power

bringing the market inside the firm academics consultants and practitioners have long advocated bringing the market inside the firm for example in the 1950 s and 1960 s economists proposed that the transferpricing problem should be solved by charging market prices for internal transactions similarly in the 1980 s financial economists suggested that the capital allocation problem should be solved by charging the external cost of capital for internal investments and wave after wave of organizational restructuring has advocated radical decentralization empowerment intrapreneurship and the like in short making employees feel like owners proponents of making transactions within firms more market like often seem to ignore the factors that brought these transactions inside firms in the first place but bengt holmstrom and paul milgrom 1991 1994 holmstrom and jean tirole 1991 and holmstrom 1999 hereafter referred to collectively as hmt remind us that in some cases integration is efficient precisely because it eliminates market incentives in such cases bringing the market inside the firm would clearly be undesirable in this paper we show that bringing the market inside the firm is often not feasible even if it would be desirable more precisely if some aspects of the market transaction are noncontractible as we define below then it is impossible to replicate spot market payoffs inside a firm this result would be trivial if the firm s only instruments were court enforceable contracts it is impossible by definition for such contracts to replicate payoffs that were noncontractible in a spot market our contribution is to show that this result also applies to relational contracts i e self enforcing agreements in repeated games to establish this result we follow sanford grossman and oliver hart 1986 hart and john moore 1990 and hart 1995 hereafter referred to collectively as ghm in using asset ownership to determine whether a particular transaction is inside a firm and hmt in adding court enforceable contracts to asset ownership models we also draw on our own work baker et al 2001 to model relational contracts the resulting model is the first we know of that simultaneously analyzes asset ownership courtenforceable contracts and relational contracts

an analysis of the principal agent problem most analyses of the principal agent problem assume that the principal chooses an incentive scheme to maximize expected utility subject to the agent s utility being at a stationary point an important paper of mirrlees has shown that this approach is generally invalid we present an alternative procedure if the agent s preferences over income lotteries are independent of action we show that the optimal way of implementing an action by the agent can be found by solving a convex programming problem we use this to characterize the optimal incentive scheme and to analyze the determinants of the seriousness of an incentive problem

utopias and realism in ecological economics knowledge understanding and improvisation what we are going through at the present time is not just an economic financial crisis but a crisis of humanity max neef 2010 p 200 despite problems within it it is ecological economics which is now emerging as the most potent opponent to neo classical economics it is ecological economics which addresses the most profound failure of neoclassical economics the failure to deal adequately with resource depletion and environmental destruction both locally and globally costanca 1991 the complex challenges are anchored in a deep conflict between mainstream economics and the natural and social conditions to harmonize this connection it would seem necessary to develop a valid understanding of the interconnectedness between economy nature and society the idea behind this article is four fold firstly we describe and discuss the ontological worldview in ecological economics secondly the epistemological consequences of the ontological preconditions are discussed thirdly some of the main concepts and principles in ecological economics are focused on fourthly we discuss the realism of radical solutions in ecological economics
