undominated coalition proof nash equilibria in quasi supermodular games with monotonic externalities abstract i introduce an undominated coalition proof nash equilibrium that is unique and is able to select undominated nash equilibria in a quasi supermodular game with a strict single crossing property and monotonic externalities

efficient and durable decision rules with incomplete information we compare six concepts of efficiency for economies with incomplete information depending on the stage at which individuals welfare is evaluated and on whether incentive constraints are recognized an example is shown in which an incentive efficient decision rule may be unanimously rejected by the individuals in the economy we define durable decision rules which can resist such unanimous rejection and show that efficient durable decision rules exist

how to improve the performance of carbon tax in china abstract the chinese government committed to controlling carbon dioxide co 2 emissions and promoting development of non fossil fuels thus it becomes a top priority for the government to develop effective climate policies against such background this paper develops a new multi country computable general equilibrium cge model with detailed energy disaggregation this study evaluates the impact of single policy instrument carbon tax and combined policy mixes in order to investigate driving factors affecting the policy performance the main findings are as follows firstly the driving factors can be classified into two types the first type of factors affects cost effectiveness significantly while the second type generates considerable effect on emission performance secondly cross border externalities function as important barriers to the co 2 emission reduction since they imply extra competitiveness loss and result in considerable carbon leakage finally this paper considers two integrated policy mixes wherein carbon tax revenue is recycled to reduce capital tax or support clean energy subsidy these policy mixes can improve both cost effectiveness and emission performance and thus perform better than carbon tax alone in this way carbon tax revenue can be used to improve the performance looking ahead complicated policy mixes are preferred to improve the performance of china s carbon tax

communication structure and coalition proofness experimental evidence abstract the paper analyzes the role of the structure of communication i e who is talking with whom in a coordination game we run an experiment in a three player game with pareto ranked equilibria where a pair of players has a profitable joint deviation from the pareto superior equilibrium we show that specific communication structures lead to different coalition proof equilibria in this game results match the theoretical predictions subjects communicate and play the pareto superior equilibrium when communication is public when pairs of players exchange messages privately subjects play the pareto inferior equilibrium even in these latter cases however players beliefs and choices tend to react to messages despite the fact that these are not credible

bargaining around cost benefit standards abstract injurers often purchase the property of potential victims to avoid liability or to comply with regulations this paper shows that injurers subject to cost benefit standards could profit from buying out victims even if they attach no value to the victims property because buyouts allow injurers to take fewer precautions a buyout of one victim produces a negative externality for the remaining victims injurers can consequently exploit victims and thereby reduce social welfare by adopting a divide and conquer strategy or by negotiating with victims sequentially perhaps surprisingly buyouts may reduce social welfare and victims joint profits even if victims make simultaneous or sequential take it or leave it buyout demands to the injurer

effects of local and civil environmental regulation on green total factor productivity in china a spatial durbin econometric analysis this paper employs metafrontier malmquist luenberger index and a spatial durbin model to investigate the influence of both local and civil environmental regulation and its spatial spillover effect on green total factor productivity in 273 cities of china in 2003 2013 according to city political attribute and regional differences this article divides the sample city into six categories the results show that effect of local environmental regulation on green total factor productivity is significantly positive in high political attribute cities a1 and a2 zone but negative effects in lower political attribute cities b2 and b3 zone moreover the race to the top results in significantly positive spatial spillover effects from local environmental regulation on green total factor productivity in high political attribute cities a1 and a2 zone while the race to the bottom causes significantly negative spatial spillover effects in lower political attribute cities b2 and b3 zone as for civil environmental regulation it has positive direct and indirect effects in promoting green total factor productivity we further find that environmental regulation inhibits the original technological innovation of enterprises which suggests that government should reduce market intervention improve enterprise flexibility of market change and promote enterprises to carry out the original technological innovation thus the government and citizen should make targeted pollution reduction policies for the green total factor productivity increase

pure strategy nash equilibrium in a group formation game with positive externalities abstract this paper identifies a domain of payoff functions in no spillover noncooperative games with positive externality which admit a pure strategy nash equilibrium since in general a nash equilibrium may fail to exist in order to guarantee the existence of an equilibrium we impose two additional assumptions anonymity and order preservation the proof of our main result is carried out by constructing for a given game g a potential function over the set of strategy profiles in such a way that the maximum of yields a nash equilibrium in pure strategies of g journal of economics literature classification numbers c72 d62 h73

a real options valuation of chinese wind energy technologies for power generation do benefits from the feed in tariffs outweigh costs abstract in order to assess the viability of wind energy projects in china this paper takes a real options approach by accounting for flexibility over deployment of the technology in response to a stochastic non renewable energy cost the difference between the latter and the r d enhanced cost of renewable energy operation may be thought of as a benefit from using wind on the other hand the chinese government provides feed in tariffs to encourage further adoption of wind which should be included as a cost this work thus shows that there is substantial options value to china s wind energy program which is bolstered if the cost of carbon dioxide emissions is internalized moreover by varying the rate of feed in tariffs the model may be used to show plausible ranges for the feed in tariffs which could be a useful policy insight furthermore the study hypothesizes that with the likelihood of renewable energy to replace non renewable energy wind power in china can potentially reduce co2 emissions by approximately 6 4 by 2020 comparing to the 2005 level and highlights the significant role of wind power in china s emission targets and energy security this is a relevant paper especially given the importance of a sustainable energy transition for china more generally using the real options approach from a policy perspective could provide insights about the viability of renewable energy programs and robustness of feed in tariffs rates

economic growth and interfactor interfuel substitution in korea this paper investigates the impact of increases in oil consumption and changes in wage rates on the interfactor interfuel substitution in korea a two stage translog cost function is estimated to incorporate the feedback effect between the interfactor and interfuel substitution empirical results show that the substitutability complementarity relationships among factors and fuels exhibit substantially different patterns before and after 1989

exclusionary pricing when scale matters we consider an incumbent firm and a more efficient entrant both offering a network good to several asymmetric buyers and both being able to price discriminate the good has positive value to buyers only if the network size exceeds a certain threshold the incumbent s installed base guarantees this critical size to the incumbent while the entrant needs to attract enough new buyers to meet this threshold we show that price discrimination in the various forms it may take reduces the set of achievable socially efficient entry equilibria and discuss the policy implications of this result

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

bond calls credible commitment and equity dilution a theoretical and clinical analysis of simultaneous tender and call stac offers this paper is an exploration of the ability of game theory to explain real world corporate maneuvering we explore this issue by investigating bond tender offers accompanied by a threat to call nontendered bonds so called simultaneous tender and call stac offers we argue that stacs engender a transparent game played by bondholders and shareholders we model this game and use this model to predict the outcome of stacs finally we investigate the issue of whether this theoretical model explains the outcomes of four actual stac issues made by james river may department stores and houston lighting power company our clinical analysis provides support for the explanatory power of our model calibrating the predictions of the model with data from these stacs we demonstrate a correspondence between theory and actual corporate behavior as predicted by our model subgame perfection or threat credibility and preplay coordination are central to explaining the outcomes of the stacs

exploring the green total factor productivity of china s metallurgical industry under carbon tax a perspective on factor substitution abstract the characteristics of high emissions and high energy consumption in metallurgical industry have brought great challenges to the green and low carbon transition in china as a low carbon economic instrument carbon tax is generally considered to be an effective way to reduce co2 emissions through raising energy cost but whether it will promote the green total factor productivity gtfp of china s metallurgical industry is still unanswered under this background this paper uses provincial panel data over years 2000 2015 to investigate the impact of carbon taxation on gtfp of metallurgical industry from the perspective of inter fuel and inter factor substitution the lock in mechanism is also incorporated in the three stage estimation model to better reflect the asymmetric price response of factors and fuels the results reveal that the slow marketization process of energy price and the rigid demand for energy in china s metallurgical industry hinder the substitution effect of energy the implementation of carbon tax has limited effect on energy saving and co2 reduction in the metallurgical industry of china and levying a carbon tax has a negative effect on gtfp during the research period therefore the government should not achieve co2 reduction targets at the expense of green economic growth gtfp is suggested to be considered in future assessment criteria in the process of transforming to low carbon economy

development of the electricity environmental policy cge model gtap e powers a case of the carbon tax in south africa abstract a new carbon price mechanism with full emission coverage is developed within the framework of a global computable general equilibrium model gtap e powers to enhance the capacity and accuracy for climate change and energy policy assessment the model developed is then used to examine the potential impacts of the carbon tax in south africa results show that incorporation of non co2 emissions in the model significantly alters the results of which the economy of south africa experiences higher costs compared to the case that only has co2 emissions when more sectors are included in the policy it also puts higher costs on the economy as higher levels of emissions are subject to the carbon tax results also show that south africa only experiences small tradeoffs from introducing the carbon tax in all scenarios that is with a tax rate of 9 15 the country is able to reduce its emission levels by 12 25 15 6 at the costs of real gdp reduction by 1 17 1 59 fossil based industrial sectors are particularly worst off while clean and renewable energy sectors strongly expand their production the results indicate that south africa is likely to move to a low carbon and sustainable economy with such a policy

remittances from international migration a review in perspective abstract remittances the portion of international migrant workers earnings sent back from the country of employment to the country of origin have come to play a central role in the economies of labor sending countries recent research has tended to focus on enumerating the costs and benefits of remittances this paper proposes an alternative perspective and delineates the remittances system as a heuristic to clarify intermediate relationships between determinants and effects of remittances using the heuristic as a framework for review of recent literature concerning remittances the paper identifies gaps in currently available research and argues for greater focus upon the social and political consequences of remittance flows

an evolutionary analysis of insurance markets with adverse selection abstract the equilibrium nonexistence problem in rothschild and stiglitz s insurance market is reexamined in a dynamic setting insurance firms are boundedly rational and offer menus of insurance contracts which are periodically revised profitable competitors contracts are imitated and loss making contracts are withdrawn occasionally a firm experiments by withdrawing or innovating a random set of contracts we show that rothschild and stiglitz s candidate competitive equilibrium contracts constitute the unique long run market outcome if innovation experiments are restricted to contracts which are sufficiently similar to those currently on the market

achieving co2 reductions in colombia effects of carbon taxes and abatement targets in this paper we investigate co2 emission scenarios for colombia and the effects of implementing carbon taxes and abatement targets on the energy system by comparing baseline and policy scenario results from two integrated assessment partial equilibrium models tiam ecn and gcam and two general equilibrium models phoenix and meg4c we provide an indication of future developments and dynamics in the colombian energy system currently the carbon intensity of the energy system in colombia is low compared to other countries in latin america however this trend may change given the projected rapid growth of the economy and the potential increase in the use of carbon based technologies climate policy in colombia is under development and has yet to consider economic instruments such as taxes and abatement targets this paper shows how taxes or abatement targets can achieve significant co2 reductions in colombia though abatement may be achieved through different pathways taxes and targets promote the entry of cleaner energy sources into the market and reduce final energy demand through energy efficiency improvements and other demand side responses the electric power sector plays an important role in achieving co2 emission reductions in colombia through the increase of hydropower the introduction of wind technologies and the deployment of biomass coal and natural gas with co2 capture and storage ccs uncertainty over the prevailing mitigation pathway reinforces the importance of climate policy to guide sectors toward low carbon technologies this paper also assesses the economy wide implications of mitigation policies such as potential losses in gdp and consumption an assessment of the legal institutional social and environmental barriers to economy wide mitigation policies is critical yet beyond the scope of this paper

household welfare and co2 emission impacts of energy and carbon taxes in mexico abstract we analyse the effects of environmental taxes on welfare and carbon emissions at the household level for the case of mexico the integrated welfare environmental analysis which is based on a censored energy consumer demand system extends previous work in two ways first the estimation of a full matrix of substitution elasticities allows us to test the necessity of incorporating second order effects into the welfare analysis second the substitution elasticities derived from the demand system are used to estimate the shortrun co2 emission reduction potential we find that first order approximations of welfare effects provide reasonable estimates particularly for carbon taxes analog to evidence in other low and middle income countries the taxation of all energy items is found to be regressive with the exception of motor fuels the analysis of the emission implications of different tax scenarios indicates that short run emission reductions at the household level can be substantial though the effects depend on how revenue is recycled this effectiveness combined with moderate and manageable adverse distributional impacts renders the carbon tax a preferred mitigation instrument considering the large effect of food price increases on poverty and the limited additional emission saving potential the inclusion of ch4 and n2o in a carbon tax regime is not advisable

all stage strong correlated equilibrium abstract a strong correlated equilibrium is a strategy profile that is immune to joint deviations different notions of strong correlated equilibria were defined in the literature one major difference among those definitions is the stage in which coalitions can plan a joint deviation before ex ante or after ex post the deviating players receive their part of the correlated profile in this paper we show that an ex ante strong correlated equilibrium is immune to deviations at all stages thus the set of ex ante strong correlated equilibria of moreno wooders games econ behav 17 1996 80 113 is included in all other sets of strong correlated equilibria

equilibrium binding agreements abstract we study equilibrium binding agreements the coalition structures that form under such agreements and the efficiency of the outcomes that result we analyze such agreements in a context where the payoff to each player depends on the actions of all other players thus a game in strategic form is a natural starting point unlike the device of a characteristic function explicit attention is paid to the behavior of the complementary set of players when a coalition blocks a proposed agreement a solution concept and its applications are discussed journal of economic literature classification numbers c70 c71

transshipment of inventories among retailers myopic vs farsighted stability the author considers a model of a decentralized distribution system consisting of n retailers selling an identical product retailers face a stochastic demand and must order their initial inventory before this demand is realized after demand realization retailers decide how much of their unsold inventory or unsatisfied demand they want to share with other retailers this is followed by a transshipment of leftover inventories and distribution of the additional profit generated through inventory sharing the author addresses the following issue suppose that the retailers distribute the profit from inventory sharing according to an allocation rule that induces retailers to share their residuals in a way that maximizes the additional profit such as the shapley value but may not belong to the core is it likely that in this framework all retailers will jointly share their residuals and not form subcoalitions previous research has looked at this problem from a myopic viewpoint and concluded that the grand coalition is not stable unlike the prior work the author looks at stability in a farsighted sense that is retailers do not consider only their immediate payoffs but are also concerned with reactions of other retailers to their actions in a symmetric setting with identical additional unit revenues from transshipments generated by all retailers farsighted retailers always maximize their allocations by not defecting from the grand coalition the author also provides conditions when the same is true for nonidentical additional unit revenues

china s energy economy technical change factor demand and interfactor interfuel substitution with its rapid economic growth china s primary energy consumption has exceeded domestic energy production since 1994 leading to a substantial expansion in energy imports particularly of oil china s energy demand has an increasingly significant impact on global energy markets in this paper allen partial elasticities of factor and energy substitution and price elasticities of energy demand are calculated for china using a two stage translog cost function approach the results suggest that energy is substitutable with both capital and labor coal is significantly substitutable with electricity and complementary with diesel while gasoline and electricity are substitutable with diesel china s energy intensity is increasing during the study period 1995 2004 and the major driver appears to be due to the increased use of energyintensive technology

competition and outsourcing with scale economies scale economies are commonplace in operations yet because of analytical challenges relatively little is known about how firms should compete in their presence this paper presents a model of competition between two firms that face scale economies i e each firm s cost per unit of demand is decreasing in demand a general framework is used which incorporates competition between two service providers with price and time sensitive demand a queuing game and competition between two retailers with fixed ordering costs and pricesensitive consumers an economic order quantity game reasonably general conditions are provided under which there exists at most one equilibrium with both firms participating in the market we demonstrate in the context of the queuing game that the lower cost firm in equilibrium may have a higher market share and a higher price an enviable situation we also allow each firm to outsource their production process to a supplier even if the supplier s technology is no better than the firms technology and the supplier is required to establish dedicated capacity so the supplier s scale can be no greater than either firm s scale we show that the firms strictly prefer to outsource we conclude that scale economies provide a strong motivation for outsourcing that has not previously been identified in the literature

do carbon taxes work analysis of government policies and enterprise strategies in equilibrium abstract to achieve the goal of carbon emission reduction a number of countries have implemented carbon tax policies and carbon pricing has become an important tool this paper discusses the interactions between a government and an enterprise for implementing carbon taxes over time or by level of tax considering greenhouse gas emission we examine the impacts of various carbon tax policies on enterprises investments in new technology their reductions in production quantity and governments tax remittances a case study of the strategic responses of three firms in taiwan s electronics cement and steel industries to two carbon emission policies promulgated by government shows that appropriate levels of tax can induce an enterprise to alter its production processes to achieve emission reduction as part of a long term business strategy

migrants remittances and financial development macro and micro level evidence of a perverse relationship financial development is commonly identified as an important condition for fostering investment and economic growth it is also believed that migrants remittances stimulate financial development in the receiving economy contributing indirectly to economic growth we explore the relationship between remittances and financial development using macro and micro level data from cross country panel data we find evidence of a negative relationship between remittances and financial deepening in developing countries using household survey data from a study of migrants remittances in two cis countries azerbaijan and kyrgyzstan we also investigate the relationship between remittances financial intermediation and financial literacy among remittance receiving households while we find some evidence of a positive albeit weak relationship for kyrgyzstan in azerbaijan the relatively more financially developed economy we uncover a strong perverse relationship remittances appear to deter bank intermediation and use of formal banking services possible reasons are explored and areas for further investigation identified

environmentally sensitive productivity growth a global analysis using malmquist luenberger index abstract we examine conventional and environmentally sensitive total factor productivity tfp in 41 developed and developing countries over the period of 1971 to 1992 due to the non availability of reliable input and co 2 emissions price data the study uses directional distance function to derive malmquist luenberger ml productivity index the index allows us to decompose the tfp into measures of technical and efficiency changes dea is used to compute the directional distance functions we find that tfp index value is not different when we account for the co 2 emissions relative to the situation when they are freely disposable but for the components of tfp change technical and efficiency changes the null hypothesis of whether the indexes are the same under two different scenarios cannot be accepted issues of catch up and convergence or in some cases possible divergence in productivity are examined within a global framework the paper also studies the impact of openness on conventional and environmentally sensitive measures of productivity

correlated equilibrium as an expression of bayesian rationality if it is common knowledge that the players in a game are bayesian utility maximizers who treat uncertainty about other players actions like any other uncertainty then the outcome is necessarily a correlated equilibrium random strategies appear as an expression of each player s uncertainty about what the others will do not as the result of willful randomization use is made of the common prior assumption according to which differences in probability assessments by different individuals are due to the different information that they have where information may be interpreted broadly to include experience upbringing and genetic makeup copyright 1987 by the econometric society

age analysis of the impact of a carbon energy tax on the irish economy a computable general equilibrium model with specific detail in taxation and energy use is developed in this paper to quantify the impact of the implementation of energy taxation to reduce carbon dioxide emissions in ireland benchmark data combining physical energy and emissions data and economic data in the form of a social accounting matrix sam had to be compiled from various data sources because energy and pollution accounts from the seea are not available for ireland we find that the reduction target for energy related co2 emissions in ireland of 25 8 compared to 1998 levels can be achieved with a carbon energy tax of 10 15 euros per tonne of co2 though fuel switching is important in meeting the target this result is more sensitive to the possibilities for producers to substitute away from energy use welfare would fall but only by small percentages production and consumption patterns would change more significantly with a shift in demand from fuels with a high emission factor to energy sources with a lower carbon intensity and from energy to other commodities this paper confirms that a carbon energy tax leads to greater emission reductions than an equivalent uniform energy tax the latter has a stronger negative impact on the less polluting energy sectors whereas the carbon tax greatly stimulates the use of renewable energy and reduces the use of peat and coal the new sam the model and the application to energy taxes contribute to a better informed debate on environmental policy in ireland

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

cheap talk with two audiences these problems have in common a simple structure an informed sender says something to two interested but uninformed receivers who then take actions based on their beliefs these actions affect the sender as well as the receivers in this paper we study how costless nonverifiable claims cheap talk can affect these beliefs and hence the actions and how the incentives for truthful revelation to one receiver are affected by the presence of the other we then ask how welfare is affected by whether claims are made in public or in private as some of the above examples suggest public messages may be more credible than private messages addressed to either audience one possibility is that the presence of one audience can discipline the sender s relationship with the other we call this one sided

large scale service marketplaces the role of the moderating firm recently large scale web based service marketplaces where many small service providers compete among themselves in catering to customers with diverse needs have emerged customers who frequent these marketplaces seek quick resolutions and thus are usually willing to trade prices with waiting times the main goal of this paper is to discuss the role of the moderating firm in facilitating information gathering operational efficiency and communication among agents in service marketplaces surprisingly we show that operational efficiency may be detrimental to the overall efficiency of the marketplace furthermore we establish that to reap the expected gains of operational efficiency the moderating firm may need to complement the operational efficiency by enabling communication among its agents the study emphasizes the scale of such marketplaces and the impact it has on the outcomes this paper was accepted by yossi aviv operations management

almost all equilibria in dominant strategies are coalition proof abstract we prove that almost all equilibria in dominant strategies of finite strategic games are coalition proof also we investigate existence of coalition proof equilibria of separable games and strategyproof mechanisms in particular we give an example of a strategyproof mechanism which is defined for strict orderings and which is coalition proof but not coalitionally strategyproof

exploring impact of carbon tax on china s co2 reductions and provincial disparities abstract with fast development it is not easy for china to achieve carbon reduction targets only by traditional command and control measures e g the measures for energy efficiency carbon tax is advocated as one effective complementary measure and has high possibility to be implemented for china s future low carbon development under such a circumstance this paper aims at forecasting the possible impact of carbon tax on both carbon reduction and economic loss of 30 chinese provinces a 30 chinese province cge computational general equilibrium model has been developed to conduct the provincial evaluation and seven scenarios including business as usual bau scenario and six carbon tax scenarios with carbon price from 20 usd ton to 120 usd ton up to 2030 are set the results show that china s industrial co2 will be reduced from 12 2 billion tons under bau scenario to 10 4 billion tons 9 3 billion tons 8 5 billion tons 7 9 billion tons 7 4 billion tons and 7 0 billion tons under scenarios of tax20 tax40 tax60 tax80 tax100 and tax120 in 2030 respectively electricity metal and chemicals sectors have high reduction potentials and are priority sectors for carbon tax policy provincial disparity analysis demonstrates that coal production consumption and total energy consumption are key factors to affect carbon tax effect on co2 reduction and inner mongolia shandong shanxi and hebei have the largest industrial co2 reduction potentials after levying carbon tax however the implementation of carbon tax will impede economic development for all provinces therefore the concept of carbon tax efficiency is further proposed in order to evaluate the effectiveness of carbon tax by considering both co2 reduction and gdp loss policy suggestions indicate that provinces of shanxi inner mongolia hebei and anhui should be set priority when implementing carbon tax policy in china and carbon price should be no more than 50 usd ton

on the coalition proofness of the pareto frontier of the set of nash equilibria abstract this article shows that the pareto efficient frontier of the nash equilibrium set of games with strategic substitutes is coalition proof under the following conditions 1 the game has three players or alternatively a player s payoff depends on her own strategy and on the sum but not on the composition of other players strategies 2 an increase in a player s strategy either raises all other players payoffs monotonically or reduces them monotonically and 3 each player s payoff is strictly concave in her own strategy under these conditions the pareto dominance refinement is equivalent to the coalition proof nash equilibrium refinement journal of economic literature classification number c72

remittances deteriorate governance abstract i use a natural experiment of oil price driven remittance flows to poor non oil producing muslim countries to demonstrate that remittances deteriorate the quality of governance especially in countries with weak democratic institutions the results indicate that a 1 standard deviation increase in remittances raises corruption by 1 5 index points on a 6 point scale which is equivalent to a dollar 600 decrease in per capita gdp concomitantly remittances may enable governments to reduce their delivery of public services for example health care school enrollment the results suggest that political institutions may mediate the potentially beneficial socioeconomic effects of remittance inflows

equilibria in a model with partial rivalry abstract in this paper we show that a non cooperative game with a finite set of players and common finite strategy sets possesses a strong nash equilibrium in pure strategies whenever individuals preferences satisfy independence of irrelevant choices anonymity and partial rivalry moreover if any of these assumptions is violated then even a pure strategy nash equilibrium may fail to exist further more we demonstrate that even with a continuum of players the same three assumptions yield the existence of a pure strategy strong nash equilibrium and in addition the equivalence of the sets of nash and strong nash equilibria in pure strategies journal of economic literature classification numbers c72 d62

approximate bertrand equilibria in a replicated industry this paper considers the existence and properties of approximate bertrand equilibria in a replicated industry price setting firms produce a homogeneous product with weakly convex costs the main results are that a given e 0 an e equilibrium exists if the industry is large enough b if the e is small enough and the industry large enough any e equilibrium is approximately competitive these results depend on how contingent demand is specified

dynamic environmental performance analysis a malmquist index approach abstract this article presents a general framework for dynamic environmental performance analysis by generalizing the approach proposed by kuosmanen and kortelainen kuosmanen t kortelainen m 2005 measuring eco efficiency of production with data envelopment analysis journal of industrial ecology 9 4 59 72 from a static to a dynamic setting for this purpose we construct an environmental performance index epi by applying frontier efficiency techniques and a malmquist index approach compared to other dynamic environmental productivity and efficiency analysis approaches based on these methods our approach builds on the standard definition of eco efficiency as it is presented in the ecological economics literature recognizing the importance to analyze the sources of environmental performance changes we show how changes in overall environmental performance can be decomposed into changes in relative eco efficiency and shifts in environmental technology respectively we apply the presented technique at the macro level to dynamic environmental performance analysis of 20 member states of the european union in 1990 2003 according to the results environmental technical change mostly explains the improvement in overall environmental performance while relative eco efficiency change has been minor for most countries during the sample period

technology adoption in the presence of network externalities we analyze technology adoption in industries where network externalities are significant the pattern of adoption depends on whether technologies are sponsored a sponsor is an entity that has property rights to the technology and hence is willing to make investments to promote it key findings include the following 1 compatibility tends to be undersupplied by the market but excessive standardization can occur 2 in the absence of sponsors the technology superior today has a strategic advantage and is likely to dominate the market 3 when one of two rival technologies is sponsored that technology has a strategic advantage and may be adopted even if it is inferior 4 when two competing technologies both are sponsored the technology that will be superior tomorrow has a strategic advantage

pricing production scheduling and delivery time competition this paper studies competition between firms that produce goods or services for customers sensitive to delay time firms compete by setting prices and production rates for each type of customer and by choosing scheduling policies the existence of a competitive equilibrium is proved the competitive equilibrium is well defined whether or not a firm can differentiate between customers based upon physical characteristics because each customer has incentive to truthfully reveal its delay cost further insights are derived in two special cases a unique equilibrium exists for each of the cases in the first case firms are differentiated by cost mean processing time and processing time variability but customers are homogeneous the conclusions include that a faster lower variability and lower cost firm always has a larger market share higher capacity utilization and higher profits however this firm may have higher prices and faster delivery time or lower prices and longer delivery time in the second

government expenditure corruption and total factor productivity abstract this paper classifies government expenditures into three types and constructs a theoretical framework to explore the influences of government expenditures and corruption on total factor productivity it then establishes a dynamic spatial autoregressive model and a panel threshold model to test the theoretical hypotheses based on provincial panel data from 2007 to 2014 the results illustrate that u shape curve relationships exist between government expenditures of administrative service investment development safeguard governance and total factor productivity and that the relationship between the government expenditure structure and total factor productivity follows an inverted u shape curve in addition the findings suggest that increased corruption levels can directly reduce regional total factor productivity and that the effects of the proportions of administrative service expenditures investment development expenditures and safeguard governance expenditures on total factor productivity have a single corruption threshold increasing the proportions of government expenditures could improve the total factor productivity up until the threshold value

stable farsighted coalitions in competitive markets in this paper we study dynamic alliance formation among agents in competitive markets we look at n agents selling substitutable products competing in a market in this setting we examine models with deterministic and stochastic demand and we use a two stage approach in stage 1 agents form alliances coalitions and in stage 2 coalitions make decisions price and inventory and compete against one another to analyze the stability of coalition structures in stage 1 we use two notions from cooperative games the largest consistent set lcs and the equilibrium process of coalition formation epcf which allow players to be farsighted thus in forming alliances players consider two key phenomena first players trade off the size of the total profit of the system versus their allocation of this total pie and second they weigh the possibility that an immediate beneficial defection can trigger further counter defections that in the end may prove to be worse than the status quo in particular one such example is that of the grand coalition which we show to be stable in the farsighted sense even though players benefit myopically by defecting from it we also provide conditions under which a situation of a few lone players competing against a large coalition is stable we examine the impact of the size of the market n the degree of competition the effect of cost parameters and the variability of the demand process on the prices inventory levels and structure of the market we discuss the possible strategic implications of our results to firms in a competitive market and for new entrants

malmquist index measurement for sustainability enhancement in chinese municipalities and provinces abstract this study discusses a use of dea environmental assessment in a time horizon we use a radial approach to examine a dynamic change of index measures related to china s regional development and industrial pollution prevention in applying the proposed assessment to a time series data we need to examine components that produce a shift of an efficiency frontier in a time horizon a unique feature of the proposed assessment is that it incorporates a framework of malmquist index to examine the frontier shift among multiple periods here the frontier shift indicates a progress potential on technology development and or managerial improvement among observed periods thus it is not an efficiency measure rather the measurement eliminates inefficiency by shifting an organization to an efficiency frontier in this study the index is conceptually separated into 6 subcomponents which are further disaggregated into 12 different elements 6 subcomponents 2 disposability concepts under natural and managerial disposability concepts the proposed index measurement needs to consider a possible occurrence of a frontier crossover among different periods because technology diffusion on production activities usually has a time lag until it becomes really effective methodologically this study conveys the message that dea is an approximation method so being not perfect therefore it is necessary for us to use several different approaches e g potential improvement by measuring a frontier shift and efficiency analysis to obtain reliable empirical evidence as an application this study examines the level of sustainability related to 30 municipalities and provinces in china from 2003 to 2014 the following six policy implications are obtained in this study first all municipalities and provinces have made a considerable progress on their economies and pollution prevention efforts second the effect of the frontier crossover is limited in china because they attain a high level of their potentials on economic development and pollution prevention of course this effort is within the chinese boundary not international because this study does not compare them with other industrial nations third china needs to allocate its resources to western provinces at a level that it has used for coastal developments fourth the government should reinforce efforts on environmental protection in central and southern regions fifth the government has focused on the sustainability development in urban municipalities and provinces and then has gradually shifted the policy influence toward rural areas finally different empirical results are confirmed by the potential analysis which consists of the malmquist index measurement and the efficiency analysis both approaches need to be examined for future planning on chinese regional development

formation of alliances in internet based supply exchanges in different industries such as automobiles chemicals or retailing competitors are joining forces in establishing electronic marketplaces to reduce inefficiencies in the purchasing process and cut costs by combining their buying power joining such an alliance leads to reduced costs including those of possible rivals because members share the development and operating costs a company that joins an alliance agrees to share its suppliers with others which may lead to more intense competition among the increased number of suppliers and it may further benefit an alliance member at the expense of companies left outside the alliance natural questions that could arise then are when would a firm prefer to take part in an electronic marketplace joint venture when would it prefer that other firms possibly rivals join the venture and what are the financial consequences of either joining an alliance or remaining independent in an attempt to gain a better understanding of the issues we have developed a model of three retailers whose products may have a certain degree of substitutability we provide some conditions in terms of product substitutability and compatibility of retailers that would lead to the formation of a three member alliance or a two member alliance or no alliance at all we also study the effect of alliance structure and compatibility of retailers on the profit of a company

cheap talk coordination and entry we show how costless nonbinding nonverifiable communication cheap talk can achieve partial coordination among potential entrants into a natural monopoly industry where the payoffs are qualitatively like the battle of the sexes the analysis would apply equally in other economic situations with such payoffs for example bargaining under complete information or choosing compatibility standards while cheap talk helps achieve asymmetric coordination in a symmetric mixed strategy equilibrium it cannot achieve complete coordination if the game involves even a small amount of conflict

coalition proof correlated equilibrium a definition a coalition proof correlated equilibrium of a game is a pair consisting of a correlation device and a coalition proof nash equilibrium of the game extended by the device a direct coalition proof correlated equilibrium is a canonical device such that the obedient strategy is a coalition proof nash equilibrium of the canonical extended game the revelation principle may not hold even for two person games direct coalition proof correlated equilibrium may fail to exist for games with more than two players for any game a pure coalition proof nash equilibrium is a direct coalition proof correlated equilibrium c 1996 academic press inc

coalition proof equilibrium we characterize the agreements that the players of a noncooperative game may reach when they can communicate prior to play but they cannot reach binding agreements a coalition proof equilibrium is a correlated strategy from which no coalition has an improving and self enforcing deviation we show that any correlated strategy whose support is contained in the set of actions that survive the iterated elimination of strictly dominated strategies and weakly pareto dominates every other correlated strategy whose support is contained in that set is a coalition proof equilibrium consequently the unique equilibrium of a dominance solvable game is coalition proof journal of economic literature classification

coalition proofness and correlation with arbitrary communication possibilities abstract the ability of the members of a coalition to communicate secretly determines whether the coalition can coordinate to deviate from a proposed strategy and thus affects which strategies are coalition proof we show that the existence of a pareto best element in the set of strategies that survive iterated elimination of dominated strategies implies the existence of a coalition proof correlated equilibrium for any specification of coalitional communication possibilities that always permits individual deviations such an element exists in games with strategic complementarities if either 1 there is a unique nash equilibrium or 2 each player s payoff is nondecreasing in the others strategies journal of economic literature classification number c72

international remittances migration and primary commodities this paper documents the global crude oil market as a key driver of international migration and remittances structural estimation documents that crude oil supply and demand shocks induce sizeable remittances flows the sign and magnitude of remitter outflows differ across countries and structural shocks a multilateral global general equilibrium model is used to show how oil exporting remitters generate international remittance and migration spillovers from crude oil price movements remittees economic outcomes from remittances and migration channels are found to be dominated by terms of trade channels for shocks to the global market for crude oil due to this studies of remittance flows need to account for the source of the commodity price movement if using the correlation between remittee real gdp and remittance inflows

the hidden economy a new view of remittances in the arab world abstract the hidden economy is set in place by the large scale migration of labor in search of employment outside national boundaries remitted earnings channeled largely through informal mechanisms have generated a network of financial and economic relations that define the boundaries and characteristic features of the hidden economy the hidden economy shapes many of the critical parameters of economic activity of the middle east such as exchange rates and the availability of foreign exchange it is difficult to observe or measure working of this important phenomenon since to a large extent it operates through unofficial informal or illegal transactions special emphasis is given to the cases of sudan and egypt to illustrate the operations of the hidden economy and to identify its agents and characteristic features

coalitional stochastic stability abstract this paper takes the idea of coalitional behavior groups of people occasionally acting together to their mutual benefit and incorporates it into the framework of evolutionary game theory that underpins the social learning literature an equilibrium selection criterion is defined which we call coalitional stochastic stability css this differs from existing work on stochastic stability in that profitable coalitional deviations are given greater importance than unprofitable single player deviations a general characterization of css is given together with more detailed characterizations for specific classes of games applications include contracting asymmetric social norms and collusive price setting the latter of which is shown in some circumstances to facilitate competitive outcomes

output elasticities and inter factor substitution empirical evidence from the transportation sector of shanghai abstract as a major consumer of fossil fuels the transportation sector in shanghai presents a wide range of problems including air pollution noise and traffic congestion this study aims to explore the energy substitution effect based on a trans log production function to evaluate the contribution of each input factor to sectoral output and reveal the substitution possibilities between capital labor and energy to deal with a multicollinearity problem we adopt ridge regression to obtain the coefficient of each variable under the appropriate penalty value the bootstrap method is used for making statistical inferences and the 95 confidence interval is obtained with 1000 bootstrap samples the empirical results demonstrate the following 1 the output elasticities of capital 0 13 0 15 labor 0 24 0 25 and energy 0 43 0 48 are positive and show an increasing trend over the study period 2 the substitution elasticity between labor and energy is the highest among the input factors around 1 0095 with a slight decreasing trend 3 the substitution elasticity between energy and capital ranges from 1 0018 to 1 0021 and the substitution elasticity between capital and labor is infinitely close to 1

fault tolerance in large games abstract a nash equilibrium is an optimal strategy for each player under the assumption that others play according to their respective nash strategies but it provides no guarantees in the presence of irrational players or coalitions of colluding players in fact no such guarantees exist in general however in this paper we show that large games are innately fault tolerant we quantify the ways in which two subclasses of large games continuous games and anonymous games are resilient against byzantine faults i e irrational behavior coalitions and asynchronous play we also show that general large games have some non trivial resilience against faults

pricing and design of differentiated services approximate analysis and structural insights we consider a model of a service system that delivers two nonsubstitutable services to a market of heterogenous users the first service is delivered subject to a guaranteed g processing rate and the second is a best effort be type service in which residual capacity not allocated to the guaranteed class isshared among be users users in turn are sensitive to both price and congestion related effects the service provider s objective is to optimally design the system so as to extract maximum revenues the design variables in this problem consist of a pair of static prices for the two services a policy that controls admission of g users into the system and the mechanism by which users are informed of the state of congestion in the system because these objectives are difficult to address using exact analysis we pursue approximations that are tractable and lead to structural insights specifically we first solve a deterministic relaxation of the original objective to obtain a fluid optimal solution that is subsequently evaluated and refined to account for stochastic fluctuations using diffusion limits we derive approximations that yield the following structural results 1 pricing rules derived from the deterministic analysis are almost optimal 2 the optimal operational regime for the system is close to heavy traffic and 3 real time congestion notification results in increased revenues numerical results illustrate the accuracy of the proposed approximations and validate the aforementioned structural insights

green productivity growth in china s industrial economy abstract this paper uses a directional distance function ddf and the malmquist luenberger productivity index to estimate the changing patterns of green total factor productivity gtfp growth of 38 chinese industrial sectors during the period 1980 2010 unlike the measures of traditional total factor productivity tfp growth the ddf incorporates carbon dioxide emissions as an undesirable output directly into the production technology which credit sectors for simultaneously reducing their emissions and increasing their output our estimates of aggregate and sector level gtfp growth reveal that chinese industry is not yet on the path towards sustainable low carbon growth a dynamic panel data analysis of the determinants of gtfp across sectors is used to identify factors that might rectify this situation including state owned enterprise soe reform the growth of small private enterprises continued openness to foreign investment and higher spending on r d particularly in emission intensive sectors

productivity growth and environmental regulations accounting for undesirable outputs analysis of china s thirty provincial regions using the malmquist luenberger index this paper employs the malmquist luenberger ml productivity index to evaluate china s growth in total factor productivity tfp incorporating undesirable outputs during the period from 1989 to 2008 the ml productivity index and its components technical and efficiency changes are derived from the directional distance function which gives credit for an increase in good outputs and for reductions in undesirable outputs the average annual ml productivity growth accounting for undesirable outputs is 2 46 whereas the value of the traditional malmquist productivity index is 4 84 showing that the true tfp growth in china is overestimated if undesirable outputs are ignored we explore the strictness in enforcing environmental regulations and its impact on improvements in ml productivity the results show that the enforcement of environmental regulations in china is in general far below the levels achieved in the best performing regions and that the more stringent enforcement of environmental regulations would help to improve ml productivity growth in china

distributional effects of a carbon tax on chinese households a case of shanghai abstract as an effective policy instrument to reduce co 2 emissions the effects of a carbon tax on distribution have been the critical factor in determining whether a carbon tax will be acceptable in china taking shanghai as an example which is the economic center and front runner of china this paper estimates the distributional effect of a carbon tax on households in various income groups by using the input output model and the suits index the results indicate that the comprehensive distributional effect of the carbon tax is regressive the expenditure of the low income group caused by the carbon tax accounts for 0 853 of the total expenditure while that of the high income group 0 712 the direct distributional effect presents a weak progressivity while the indirect one is significantly regressive and the latter is much larger than the former moreover the suits index of the carbon tax is 0 078 implying that the carbon tax burden on the low income group is the highest and thus that a carbon tax can intensify income inequality therefore when introducing a carbon tax some rational associated redistribution or compensation measures such as purposive transfer payments should be implemented to restrict or even eliminate the regressivity of the carbon tax

pricing and capacity sizing for systems with shared resources approximate solutions and scaling relations this paper considers pricing and capacity sizing decisions in a single class markovian model motivated by communication and information services the service provider is assumed to operate a finite set of processing resources that can beshared among users however this shared mode of operation results in a service rate degradation users in turn are sensitive to the delay implied by the potential degradation in service rate and to the usage fee charged for accessing the system we study the equilibrium behavior of such systems in the specific context of pricing and capacity sizing under revenue and social optimization objectives exact solutions to these problems can only be obtained via exhaustive simulations in contrast we pursueapproximate solutions that exploitlarge capacity asymptotics economic considerations and natural scaling relations demonstrate that the optimal operational mode for the system is close to heavy traffic this in turn supports the derivation of simple approximate solutions to economic optimization problems via asymptotic methods that completely alleviate the need for simulation these approximations seem to be extremely accurate the main insights that are gleaned in the analysis follow congestion costs are small the optimal price admits a two part decomposition and the joint capacity sizing and pricing problem decouples and admits simple analytical solutions that are asymptotically optimal all of the above phenomena are intimately related to statistical economies of scale that are an intrinsic part of these systems

factor and fuel substitution in china s iron steel industry evidence and policy implications climate change which is induced from energy consumption and co2 emissions has got people s attention hence many strategies and ways are being adopted to mitigate co2 emissions energy substitution is crucial to the promotion of energy conservation and co2 emissions reduction the purpose of this paper is to estimate both inter factor and inter fuel substitution in china s iron steel industry during the period 1985 2011 empirical results show several conclusions for china s iron steel industry 1 own price elasticity of energy is negative so increase in energy price will reduce energy input 2 energy and capital and energy and labor are substitutes and the substitution in energy capital is relatively stronger 3 though coal oil and electricity are also substitutes the substitution effect is not so obvious because of pricing distortions in china the driving forces of energy efficiency change are further discussed and the results show that technology progress is the key factor determining energy intensity therefore market oriented reforms in terms of energy prices improvement in energy substitution including inter factor and inter fuel substation and promotion of energy saving technologies are important means for ensuring future energy conservation and co2 emissions reduction practices in china s iron steel sector

does factor market distortion inhibit the green total factor productivity in china abstract this article measures green total factor productivity gtfp to discuss whether factor market distortions inhibit the green development of china s economy meanwhile export and foreign direct investment fdi are taken into account based on a threshold model considering export and fdi are closely related to factor market distortion environment and the economy the result shows that the factor market distortion has negative influences on china s gtfp growth export and fdi s spillover effect significantly moreover factor market distortion was found to be the threshold of export and fdi s spillover effect leading to inferior export and fdi which further inhibit gtfp growth this article provides a supplement to the issue from the perspective of environment based on the widely confirmed proposition that factor market distortion inhibits tfp growth according to the results we suggest that the chinese government should reduce the control of factor market as much as possible leaving the factor resources allocation to the market this will not only promote an innovation driven development but also an energy saving and environment friendly economy in china the article provides a new perspective on the influence mechanism of export and fdi on gtfp growth by discussing the impact path of factor distortion and expands the empirical framework of the research direction as well

impact of a carbon tax on the chilean economy a computable general equilibrium analysis abstract in 2009 the government of chile announced their official commitment to reduce national greenhouse gas emissions by 20 below a business as usual projection by 2020 due to the fact that an effective way to reduce emissions is to implement a national carbon tax the goal of this article is to quantify the value of a carbon tax that will allow the achievement of the emission reduction target and to assess its impact on the economy the approach used in this work is to compare the economy before and after the implementation of the carbon tax by creating a static computable general equilibrium model of the chilean economy the model developed here disaggregates the economy in 23 industries and 23 commodities and it uses four consumer agents households government investment and the rest of the world by setting specific production and consumptions functions the model can assess the variation in commodity prices industrial production and agent consumption allowing a cross sectoral analysis of the impact of the carbon tax the benchmark of the economy upon which the analysis is based came from a social accounting matrix specially constructed for this model based on the year 2010 the carbon tax was modeled as an ad valorem tax under two scenarios tax on emissions from fossil fuels burned only by producers and tax on emissions from fossil fuels burned by producers and households the abatement cost curve has shown that it is more cost effective to tax only producers rather than to tax both producers and households this is due to the fact that when compared to the emission level observed in 2010 a 20 emission reduction will cause a loss in gdp of 2 and 2 3 respectively under the two scenarios the tax value that could lead to that emission reduction is around 26 us dollars per ton of co2 equivalent the most affected productive sectors are oil refinery transport and electricity having a contraction between 7 and 9 analyzing the electricity sector by energy source the production of electricity from fossil fuels will decrease by 11 but electricity from renewables will increase by 43 electricity producers will pass the cost of the carbon tax to the consumer by increasing the price of electricity by 8 the findings of this paper will allow policy makers to take better and more informed decisions by providing a cross sectoral analysis of the impact on the economy of reducing emissions by 20 by implementing a national carbon tax
