adoption of new tobacco varieties in greece impacts of empirical findings on policy design abstract greece is a major international tobacco producer flue cured tobacco varieties constituted the major alternative crop to greek farmers growing certain oriental tobacco varieties diffusion of flue cured tobacco was rapid due to its high yields and the depressed market for certain oriental tobacco varieties currently the common organisation of the tobacco market is undergoing substantial changes and the farmers response will be a vital factor of success a portfolio selection model reveals that the major factors influencing the adoption decision of tobacco growers are the size of the farm measured in annual work units the farm s proximity to urban centres the farm s diversification and the farmer s age the number of contacts with institutions is surprisingly inversely related to adoption future tobacco policies impinging on factors influencing decisions to adopt new varieties or production practices may be more cost effective

pillage and property this paper introduces a class of coalitional games called pillage games as a model of hobbesian anarchy any coalition can pillage costlessly and with certainty any less powerful coalition power is endogenous so a pillage game does not have a characteristic function but pillage provides a domination concept that defines a stable set which represents an endogenous balance of power every stable set contains only finitely many allocations and can be represented as a farsighted core additional results are obtained for particular games including the game in which the power of each coalition is determined by its total wealth

land use and economic effects of alternative biofuel policies in brazil and the united states being the two largest ethanol producers in the world biofuel policies in brazil and the united states affect both their domestic markets and the global food and biofuel economy in this article we develop a price endogenous mathematical programming model to simulate and analyze the impacts of biofuel mandates and trade distortions on land use agricultural commodity and transportation fuel markets and global environment we find that an 80 increase in total biofuel production from its 103 billion liter baseline level to the mandated 183 billion liter level in 2022 can be achieved with less than 2 increase in total cropland use in both countries in the united states this would occur with cellulosic biofuels meeting nearly half of the biofuels consumed and produced largely on cropland pasture and corn ethanol meeting the rest of the mandate and resulting in a 2 increase in corn price in brazil the expansion in sugarcane production would be achieved by reducing land under pasture and a marginal increase in intensification of livestock production in the aggregate biofuel policies increase economic surplus in both countries by 1 and redistribute the benefits from agricultural consumers to agricultural producers and the fuel sector finally we also find that full implementation of the mandates in north america china and the european union would reduce the global life cycle global greenhouse gas emissions by about 5

the induced innovation hypothesis and energy saving technological change we develop a methodology for testing hicks s induced innovation hypothesis by estimating a product characteristics model of energy using consumer durables augmenting the hypothesis to allow for the ine uence of government regulations for the products we explored the evidence suggests that i the rate of overall innovation was independent of energy prices and regulations ii the direction of innovation was responsive to energy price changes for some products but not for others iii energy price changes induced changes in the subset of technically feasible models that were offered for sale iv this responsiveness increased substantially during the period after energy efficiency product labeling was required and v nonetheless a sizable portion of efficiency improvements were autonomous

human capital producer education programs and the adoption of forward pricing methods using a sample of 509 kansas producers we evaluate factors affecting adoption of forward pricing methods we focus on producers human capital accumulation and its effect on adoption of forward pricing techniques probit models are employed to evaluate producers participation in educational programs and their forward pricing adoption decisions tobit models are employed to evaluate individual levels of adoption of these techniques in the marketing of wheat corn grain sorghum soybeans and cattle

political bias and war we examine the incentives for countries to go to war as they depend on the comparison between how much their pivotal decision makers have at risk and how much they stand to gain from a war how this ratio compares to the country at large is what we term political bias if there is no political bias then there are always payments that one country would like to make to the other that will avoid a war in the presence of commitment or enforceability of peace treaties if there is a bias on the part of one or both countries then war can result and in some cases cannot be prevented by any transfer payments we examine how war technology and relative wealth levels interact with political bias in determining whether countries make transfers go to war and form alliances our results shed some new light on the uneven contender paradox and the interpretation of the democratic peace

understanding the reductions in us corn ethanol production costs an experience curve approach the us is currently the world s largest ethanol producer an increasing percentage is used as transportation fuel but debates continue on its costs competitiveness and energy balance in this study technological development of ethanol production and resulting cost reductions are investigated by using the experience curve approach scrutinizing costs of dry grind ethanol production over the timeframe 1980 2005 cost reductions are differentiated between feedstock corn production and industrial ethanol processing corn production costs in the us have declined by 62 over 30 years down to 100 2005 tonne in 2005 while corn production volumes almost doubled since 1975 a progress ratio pr of 0 55 is calculated indicating a 45 cost decline over each doubling in cumulative production higher corn yields and increasing farm sizes are the most important drivers behind this cost decline industrial processing costs of ethanol have declined by 45 since 1983 to below 130 2005 m3 in 2005 excluding costs for corn and capital equivalent to a pr of 0 87 total ethanol production costs including capital and net corn costs have declined approximately 60 from 800 2005 m3 in the early 1980s to 300 2005 m3 in 2005 higher ethanol yields lower energy use and the replacement of beverage alcohol based production technologies have mostly contributed to this substantial cost decline in addition the average size of dry grind ethanol plants increased by 235 since 1990 for the future it is estimated that solely due to technological learning production costs of ethanol may decline 28 44 though this excludes effects of the current rising corn and fossil fuel costs it is also concluded that experience curves are a valuable tool to describe both past and potential future cost reductions in us corn based ethanol production

farsighted coalitional stability abstract i define the largest consistent set a solution concept which applies to situations in which coalitions freely form but cannot make binding contracts act publicly and are fully farsighted in that a coalition considers the possibility that once it acts another coalition might react a third coalition might in turn react and so on without limit i establish weak nonemptiness conditions and apply it to strategic and coalitional form games and majority rule voting i argue that it improves on the von neumann morgenstern stable set as it is usually defined but is consistent with a generalization of the stable set as in the theory of social situations journal of economic literature classification numbers c70 c71

farsighted stability in patent licensing an abstract game approach abstract this paper analyzes the negotiations made by an external patent holder and potential licensee firms in a new model of patent licensing assuming that they are all farsighted and characterizes the symmetric farsighted stable sets given a net profit of each licensee firm a set of outcomes is a symmetric farsighted stable set if and only if at any outcome in the set each licensee firm receives the net profit and the number of licensee firms maximizes the patent holder s profit provided that licensee firms obtain the net profits we also show the close relationship between the symmetric farsighted stable sets and the relative interior of the core further we confirm that the symmetric farsighted stable sets are the absolutely maximal farsighted stable sets ray and vohra forthcoming as well as the history dependent strongly rational expectation farsighted stable sets dutta and vartiainen forthcoming

adoption of agricultural innovations in developing countries a survey this paper reviews various studies which have provided a description and possible explanation to patterns of innovation adoption in the agricultural sector the survey points out that the tendency of many studies to consider innovation adoption in dichotomous terms adoption nonadoption may not be appropriate in many cases where the actual decisions are defined over a more continuous range more attention needs to be given to the socio cultural and institutional environment in area studies so that their interrelation with economic factors affecting adoption can be inferred the presence of several interrelated innovations is another aspect that needs to be considered more carefully in future research since a number of simultaneous decisions may be involved furthermore the possibility of regular sequential patterns in adopting components of a new technological package should be specifically addressed in future studies finally the impact of differential adoption rates on land holding distribution merits attention in future research

job queues and the union status of workers this paper develops a model of the determination of the union status of workers that allows for the possibility of queuing for union jobs the empirical results derived using a sample from the university of michigan panel study of income dynamics are supportive of the queuing hypothesis the no queue model can be rejected using a likelihood ratio test this suggests that a simple probit or logit model for union status is misspecified because it is not based on any consistent behavioral theory an important implication of the model is that because most new entrants to the labor market prefer union jobs but cannot get them and because accrual of nonunion seniority makes workers progressively less likely to desire union jobs the union status of workers is largely determined by their success in being selected from the queue early in their working life

conservation agriculture organic marketing and collective action in the honduran hillsides conservation agriculture ca is often perceived to provide win win outcomes for farmers leading to reduced erosion and off site sedimentation as well as improved soil fertility and productivity however adoption rates for ca in many regions of the world remain below expected levels this article looks at the effects of participation in organic markets and farmers organizations on the adoption of soil conservation practices based on original survey data from 241 small scale farm households in honduras we find that both participation in organic markets and farmer based groups have positive effects on the number of soil conservation practices adopted the results indicate that besides supply oriented policy measures such as the provision of technical assistance and extension demand related factors are likely to play an important role in sustainable soil management demand oriented policy measures include support for labeling initiatives and consumer education to facilitate value added product differentiation and market segmentation jel classifications q01 q12 q13 q16

an economic perspective on experience curves and dynamic economies in renewable energy technologies this paper analyzes dynamic economies in renewable energy technologies the paper has two contributions the first is to test the robustness of experience in solar photovoltaic solar thermal and wind energy to the addition of an explicit time trend which has been done in experience studies for other industries but not for renewable energy technologies estimation is carried out on the assumption that cumulative capacity industry production average firm production and electricity generation affect experience and thus the fall in price the second contribution is to test the impact of r d on price reduction in general cumulative experience is found to be highly statistically significant when estimated alone and highly statistically insignificant when time is added to the model the effect of r d is small and statistically significant in solar photovoltaic technology and statistically insignificant in solar thermal and wind technologies

endowments technology and factor markets a natural experiment of induced institutional innovation from china s rural reform the induced institutional innovation hypothesis postulates that new institutions are innovated to exploit profitable opportunities arising from institutional disequilibrium the removal of legal restrictions on factor market exchanges after recent reforms in china resulted in institutional disequilibrium this paper utilizes data from a household survey in china to explore i the relationship between the emergence of land labor and rental markets in a region and the distribution of factor endowments across rural households in that region and ii the impact of hybrid rice on the emergence of factor markets in that region the results are consistent with the induced institutional innovation hypothesis

unconventional adjustment strategies for rural households in the less developed areas in greece abstract international competition in agricultural production is intensifying following the implementation of the 1993 accord of the general agreement on tariffs and trade the production of conventional farm products in surplus is being discouraged by means of indirect economic disincentives the common agricultural policy has already adjusted to unprotected national markets within the european union and greater market orientation is being achieved mainly through price reductions farmers in the less developed areas in greece where agricultural activity is still the main source of income and employment have been responding to policy reforms by seeking part time employment and income in non farm enterprises the adoption of alternative unconventional farm enterprises that use farm resources in an innovative and quantitatively different way does have the potential for bringing in a new source of income to farm business for the purpose of this research three adjustment strategies were recognised the conventional no change pathway is based on traditional region specific products production methods and services the adoption of the new crop pathway refers to the redeployment of resources into new agricultural products whereas farms on the market integration pathway redeploy resources into new marketing services and agricultural product processing on the farm the new crop and the market integration pathways are identified as unconventional adjustment strategies results derived from multinomial logit analysis highlight the major constraints and opportunities associated with the adoption of new crops and market integration practices farmers who have adopted unconventional practices are influenced by factors external to the farm such as contacts with institutions and have a high probability of having higher debts these farmers are likely to depend heavily on seasonal labour and rented land the fact that market integration activities are associated with smaller farms in conjunction with off farm work signifies the importance of establishing an integrated rural development policy approach public policy involvement in enhancing dissemination of information concerning unconventional enterprises is emphasised

the household responsibility system reform and the adoption of hybrid rice in china abstract this paper studies the diffusion of hybrid rice before and after the recent institutional change from the collective team system to the household based farming system in rural china a simple model which treats the adoption of hybrid rice as a portfolio selection problem is presented the model is tested against time series cross county data collected from hunan province in south china the empirical evidence suggests that 1 adoption behavior in the collective system was not consistent with the predictions of the theoretical model this evidence indicates the existence of administrative intervention in influencing production decisions in the collective system 2 there was a significant change in the structure of the adoption function following the transition from the collective system to the household based system and 3 adoption behavior in the household system is consistent with the predictions of the theoretical model

quasi maximum likelihood estimation of multivariate probit models farm couples labor participation joint estimation of farmers farm and off farm work participation requires a multivariate probit model in which the number of equations is twice the number of household members where there are more than two such equations i suggest a quasi maximum likelihood method which requires only two levels of numerical integration the method maximizes the use of sample information given this numerical feasibility condition it is used for estimating a joint participation model of farm couples farm and off farm work the model yields conclusions about comparative advantages of men and women in farm off farm and housework which cannot be obtained with a more limited setup

technical change dynamics evidence from the emerging renewable energy technologies abstract this paper explores the respective contributions of the effects of learning and returns to scale in the capital costs reduction pattern experienced by renewables causality analysis and econometric estimation of learning curves are performed on two emerging renewable energy technologies namely pv and wind learning effects appear as an essential driving force a result which concurs with the widely acknowledged importance of experience in technical progress inherent to economic growth the existence of non constant and flexible returns to scale are further highlighted their effect on diffusion dynamics is shown to be potentially considerable particularly at the outset of innovation deployment however returns to scale are suggested to be constant in the long term institutional commitment in supporting innovation therefore seems justified both on the basis of the occurrence of learning effects and diseconomies of scale these findings appear to be essential to the dynamics of innovation diffusion and market structure

adoption of agricultural innovations as a two stage partial observability process in this paper we reconsider the appropriateness of certain statistical analyses in innovation adoption studies and suggest that partial observability models may sometimes be more useful the proposed models allow for a flexible specification of the process of adoption from one stage to two stages facilitate the modelling of non adopters and remedy the violation of the assumption of full information an application to the adoption of organic cultivation in greece demonstrates the relative merits of the proposed analysis

anarchy and its breakdown anarchy defined as a system in which participants can seize and defend resources without regulation from above is not chaos but rather a spontaneous order however anarchy is fragile and may dissolve either into formless amorphy or into a more organized system such as hierarchy under anarchy each contestant balances between productive exploitation of the current resource base and fighting to acquire or defend resources anarchy is sustainable only when there are strongly diminishing returns to fighting effort the decisiveness parameter is sufficiently low and incomes exceed the viability minimum these considerations explain many features of animal and human conflict

dynamic stability and reform of political institutions abstract this paper examines endogenous institutional change in a class of dynamic political games the political aggregation rules used at date t 1 are instrumental choices under rules at date t effectively rules are players who can strategically delegate future policy making authority to different rules a political rule is stable if it selects itself a reform occurs when an alternative rule is selected the stability of a political rule is shown to depend on whether its choices are dynamically consistent for instance simple majority rules can be shown to be dynamically consistent in many common environments where wealth weighted voting rules are not the result extends to political rules that incorporate private activities such as extra legal protests threats or private investment the approach is one way of understanding various explanations of institutional change proposed in the literature a parametric model of public goods provision gives an illustration

technological learning in energy environment economy modelling a survey abstract this paper aims at providing an overview and a critical analysis of the technological learning concept and its incorporation in energy environment economy models a special emphasis is put on surveying and discussing through the so called learning curve both studies estimating learning rates in the energy field and studies incorporating endogenous technological learning in bottom up and top down models the survey of learning rate estimations gives special attention to interpreting and explaining the sources of variability of estimated rates which is shown to be mainly inherent in r d expenditures the problem of omitted variable bias the endogeneity relationship and the role of spillovers large scale models survey show that despite some methodological and computational complexity related to the non linearity and the non convexity associated with the learning curve incorporation results of the numerous modelling experiments give several new insights with regard to the analysis of the prospects of specific technological options and their cost decrease potential bottom up models and with regard to the analysis of strategic considerations especially inherent in the innovation and energy diffusion process in particular the energy sector s endogenous responses to environment policy instruments top down models

taking a new look at empirical models of adoption average treatment effect estimation of adoption rates and their determinants this article shows that the observed sample adoption rate does not consistently estimate the population adoption rate even if the sample is random it is proved that instead the sample adoption rate is a consistent estimate of the population joint exposure and adoption rate which does not inform about adoption per se likewise it is shown that a model of adoption with observed adoption outcome as a dependent variable and where exposure to the technology is not observed and controlled for cannot yield consistent estimates of the determinants of adoption the article uses the counterfactual outcomes framework to show that the true population adoption rate corresponds to what is defined in the modern policy evaluation literature as the average treatment effect ate which measures the effect or impact of a treatment on a person randomly selected in the population in the adoption context a treatment corresponds to exposure to the technology the article uses the ate estimation framework to derive consistent nonparametric and parametric estimators of population adoption rates and their determinants and applies the results to consistently estimate the population adoption rates and determinants of the nerica new rice for africa rice varieties in c ote d ivoire the ate methodological approach developed in the article has significant policy implications with respect to judging the intrinsic merit of a new technology in terms of its potential demand by the target population independently of issues related to its accessibility and in terms of the decision to invest or not in its wide scale dissemination

international competitiveness technical change and the state the machine tool industry in taiwan and japan abstract it is widely accepted that the growth performance of japan and the asian newly industrialized countries hong kong singapore south korea and taiwan is partly the result of the international competitiveness they have achieved in a number of export industries it remains however to explain how this competitiveness was achieved in the first part of the paper an attempt at such an explanation based on the theory of comparative advantage is critically examined it is argued that while this explanation does have some explanatory power it does not deal adequately with a the role of technical and productivity change b the causal mechanisms underlying economic growth and c the role of the state the rest of the paper examines the case of machine tools in taiwan and japan showing the importance of these three factors as well as a number of others as determinants of international competitiveness the paper ends with a discussion of policy dilemmas relating to international competitiveness in the taiwanese machine toot industry

education and innovation adoption in agriculture evidence from hybrid rice in china this paper uses the diffusion of f1 hybrid rice as a case for examining the effects of education on the adoption of new technology in china a simple behavioral model that treats the adoption of hybrid rice as a portfolio selection problem is presented the implications of the model are tested with farm level data collected from a sample of 500 households in hunan province the results from a dichotomous probit model and a two limit tobit model are consistent with the hypothesis that education has a positive impact on the adoption of new technology

explaining the reductions in us corn ethanol processing costs testing competing hypotheses abstract the processing costs of us corn ethanol have declined by 45 since 1983 as production volumes have increased seventeen fold we investigate the role of various factors that could explain this including economies of scale cumulative experience induced innovation in response to rising input prices an autonomous technological change and trade induced competition from imported ethanol using data on dry mill ethanol processing costs over the 1983 2005 period we find evidence to show that us corn ethanol production exhibited decreasing returns to scale that learning by doing played an important role in reducing these processing costs with a learning rate of 0 25 and that sugarcane ethanol imports contributed to making the corn ethanol industry more competitive other factors such as the rising prices of energy and labor did induce lower processing costs but the effect is not statistically significant the inclusion of these competing explanations for the reduction in processing costs of us corn ethanol lead to a significantly higher learning rate than otherwise and this learning rate is found to be robust across specifications

induced innovation and energy prices this paper uses u s patent data from 1970 to 1994 to study the impact of energy prices on energy efficient innovations theories of technological change have focused both on demand side factors which spur innovative activity by increasing the value of new innovations and supply side factors such as scientific advancements that make new innovations possible data on demand side factors are easily obtained but data on supply side factors that influence innovation are not readily available this paper uses patent citations as a measure of the usefulness of the existing base of scientific knowledge citations to previous patents are used to construct productivity estimates which measure the usefulness of the existing stock of knowledge to inventors in a given energy field for any given year these estimates are then combined with data on demand side factors to estimate a model of induced innovation in energy technologies the results indicate that both energy prices and the supply of knowledge have strongly significant positive effects on innovation the paper concludes with a discussion of the implication of this work for environmental policy

market imperfections access to information and technology adoption in uganda challenges of overcoming multiple constraints limited empirical evidence exists on how multiple binding constraints influence the adoption of improved technologies by smallholder farmers this article uses the case of groundnut variety adoption in uganda to investigate the role of information seed supply and credit constraints in conditioning technology uptake new data from a household survey in seven groundnut growing districts n 945 indicate that 8 of farmers lack information on new varieties while 18 and 6 of farmers respectively cannot adopt mainly due to seed supply and capital constraints a tobit type specification that considers all nonadopters as being uninterested in the technology i e corner solutions would lead to inconsistent parameter estimates and incorrect conclusions in this context we therefore estimate a modified multi hurdle specification of demand for new varieties taking into account how information seed supply and capital constraints jointly determine adoption probability and intensity the study reveals new empirical insights on why agricultural technology adoption in africa has lagged behind slow uptake is not mainly due to a lack of economic incentives but rather a reflection of information seed supply and credit constraints that prevent farmers from translating their desired demand into adoption of modern varieties policy implications are discussed

spatial patterns of organic agriculture adoption evidence from honduras in low potential agricultural areas like the honduran hillsides characterized by soil degradation and erosion organic agriculture can provide a means to break the downward spiral of resource degradation and poverty we use original survey data to analyze the factors influencing the decision to convert to organic agriculture previous studies have emphasized the role of spatial patterns in the diffusion and adoption of agricultural technologies in general and organic agriculture in particular these spatial patterns can result from a variety of underlying factors in this article we test various potential explanations including the availability of information in the farmer s neighborhood social conformity concerns and perceived positive external effects of the adoption decision in a spatially explicit adoption model we find that farmers who believe to act in accordance with their neighbors expectations and with greater availability of information in their neighborhood network are more likely to adopt organic agriculture furthermore perceived positive productivity spillovers to neighboring plots decrease the probability of adoption we discuss the implications of our findings for the dissemination of sustainable agricultural technologies in low potential agricultural areas in developing countries

conversion subsidies for organic production results from sweden and lessons for the united states organic conversion subsidies used in europe are less likely to be politically acceptable in the united states where organic agriculture development is market driven persistent barriers to conversion in the united states include limited availability of and access to production and market information training in management systems and cost of conversion related investments by determining whether these factors affect the requirement of a subsidy to convert we can suggest whether u s policy makers need to provide subsidies to encourage conversion and identify policy variables consistent with market based approaches that could stimulate conversion a utility difference model is used with swedish data to analyze factors that determine whether a subsidy is required to motivate organic conversion the results show that farmers requiring subsidies manage larger less diversified farms and are more concerned with organic inspection quality and adequacy of technical advice access to more market outlets and information sources substitutes for payment level in the farmer s utility function indicating that services rather than subsidies may be used to encourage organic agriculture to the extent that conditions are similar in the u s organic sector market based programs such as cost sharing for conversion and market access improvement should stimulate growth of this industry 2000 elsevier science b v all rights reserved

balance of power and the propensity of conflict we study the role of an imbalance in fighting strengths when players bargain in the shadow of conflict our experimental results suggest in a simple bargaining game with an exogenous mediation proposal the likelihood of conflict is independent of the balance of power if bargaining involves endogenous demand choices however the likelihood of conflict is higher if power is more imbalanced even though endogenous bargaining outcomes reflect the players unequal fighting strengths strategic uncertainty causes outcomes to be most efficient when power is balanced in turn the importance of exogenous mediation proposals depends on the balance of power

unraveling effects of coal output cut policy on air pollution abatement in china using a cge model abstract recently frequent hazy weather in china caused by pm2 5 is mainly attributed to irrational energy consumption structure so the policies cutting coal output and promoting electric power substitution were initiated facing some resistance in the policy implementation what the proper target of cutting coal output is or whether there is a need to cut electricity prices for electric power substitution are still unknown or debatable to exploring this knowledge gap this paper set the eight action plan policy scenarios in which the coal output cut is set from 3 to 10 respectively further in order to observe whether the policy of cutting electric price will reduce the negative effects of action plan policy scenarios the eight enhanced action plan policy scenarios were also set in which the coal output cut is set from 3 to 10 respectively with the hypothetical electric price cut 3 by using the developed computable general equilibrium cge model the policy scenarios are simulated and the economic and environmental effects are tested the results showed that first in most policy scenarios the environmental and economic effects were changing synchronously in inverted u shapes but the policy to cut coal output would lead to positive environmental effects and negative economic effects second cutting electricity price could contribute to promoting electricity substitution though it couldn t be conducive to improving the electricity structure third the reduction of electricity price could also help to reduce the resistance in policy implementation consequently for optimal environmental effects and economic resistance it is recommended to set the policy target of cutting coal output as 6 while the moderate reduction of electricity price is needed and set as 3

the dynastic cycle and the stationary state a dynastic cycle is a periodic alternation of society between despotism and anarchy in a society of farmers rulers and bandits population growth simultaneously impoverishes farmers and reduces the ruler s surplus per head society evolves into a despotic stationary state or into a dynastic cycle dependent on whether poverty among farmers chokes off population growth before the surplus shrinks to the point where rulers turn to banditry copyright 1989 by american economic association

coalition bargaining in repeated games we consider an intertemporal game theoretic framework in which different coalitions interact repeatedly over time both the terms of trade and the endogenous cooperation structure arising in this setup are characterized in a protocol free manner provided that just three natural conditions on the outcome are satisfied c1 a coalition is formed with positive probability if and only if the shares obtained in this case by its members weakly exceed their respective share expectations c2 each matched coalition distributes the entire surplus among its members c3 members of any coalition are treated symmetrically with respect to their share expectations when the surplus of this coalition is distributed our analysis primarily focuses on the limit scenario where the game ends each date with vanishing probability we show that in this case the cooperation structure and the shares are unique in an application to trade networks we show that in a complete network a unique price arises and agents specialize in either buying or selling in an incomplete network on the other hand transactions occur generally at multiple prices and some agents become arbitrageurs that buy and sell at different prices
