communication networks in markets abstract this paper proposes and tests experimentally a dynamic model of bargaining to analyze decentralized markets where buyers and sellers obtain information about past deals through their social network there is a unique equilibrium in which every individual obtains the same outcome independent of their network position and this outcome depends on the peripheral least connected individuals in the network the main testable predictions are that networks with high density and or low variability in the number of connections across individuals allow their members to obtain a better deal these predictions are tested in a lab experiment through 4 treatments that vary the network that subjects are assigned to the results of the experiment lend support to the theoretical predictions subjects converge to an outcome that is independent of their network position and they fare better if they are assigned to a network that is dense and or has low variability in number of connections across members

trade openness and the environmental kuznets curve evidence from chinese cities this paper examines the impact of economic growth and trade openness on environment in 261 chinese cities over the period of 2004 2013 using recently developed continuously updated fully modified method which allows for both cross sectional dependence and endogeneity two types of pollutants industrial waste water and sulphur dioxide are investigated and three measures of openness are employed in the regression from the results we find that the environmental kuznets curve hypothesis holds not only for the whole china but also in different regions it is estimated that wastewater pollution increases with economic development until per capita gdp reaching the turning point of 42 991 48 828 yuan in constant 2002 price which varies depending on the specific measure of trade openness the turning point for sulphur dioxide is found to occur at a much lower income level around 9 588 10 663 yuan per capita gdp furthermore export is mostly found to be positively related with pollution and the impact of import is likely to be negative for both the whole china and across regions if the significance is identified in the estimation results

regulation factor rewards and international trade this paper develops an approach for incorporating regulation into the theory of production distribution and trade using environmental regulation as an example four major conclusions emerge in the course of the analysis 1 production process regulation is equivalent in its effect on other cooperating factors to neutral technical regress i e negative progress 2 specific unambiguous income redistribution consequences follow from such regulation if commodity prices are held constant the factor used relatively intensively in the non regulated industry will gain absolutely in terms of both goods 3 unilateral or uncoordinated regulation destroys the link between uniform world commod ity prices and identical factor proportions factors prices across trading countries or regions 4 if any factor of production is freely mobile across frontiers the least differential regulation as between countries will entirely drive out the regulated industry from the more to the less regulated economy

public goods in networks this paper considers incentives to provide goods that are non excludable along social or geographic links we find first that networks can lead to specialization in public good provision in every social network there is an equilibrium where some individuals contribute and others free ride in many networks this extreme is the only outcome second specialization can benefit society as a whole this outcome arises when contributors are linked collectively to many agents finally a new link increases access to public goods but reduces individual incentives to contribute hence overall welfare can be higher when there are holes in a network

behavioural tax microsimulation with finite hours choices abstract it is often argued that institutional factors constrain the labour supply choices open to the individual in this paper we present an alternative to the standard neoclassical model of labour supply under the presumption that the number of hours choices are discrete and finite we explore alternative specifications of discrete models of labour supply which are appropriate for the microsimulation of the behavioural impact of tax policy reform policy simulations are carried out for a basic income reform

confronting the environmental kuznets curve t he environmental kuznets curve posits an inverted u relationship between pollution and economic development kuznets s name was apparently attached to the curve by grossman and krueger 1993 who noted its resemblance to kuznets s inverted u relationship between income inequality and development in the first stage of industrialization pollution in the environmental kuznets curve world grows rapidly because people are more interested in jobs and income than clean air and water communities are too poor to pay for abatement and environmental regulation is correspondingly weak the balance shifts as income rises leading industrial sectors become cleaner people value the environment more highly and regulatory institutions become more effective along the curve pollution levels off in the middle income range and then falls toward pre industrial levels in wealthy societies the environmental kuznets curve model has elicited conflicting reactions from researchers and policymakers applied econometricians have generally accepted the basic tenets of the model and focused on measuring its parameters their regressions typically fitted to cross sectional observations across countries or regions suggest that air and water pollution increase with development until per capita income reaches a range of 5000 to 8000 when income rises beyond that level pollution starts to decline as shown in the conventional ekc line in figure 1 in developing countries some policymakers have interpreted such results as conveying a message about priorities grow first then clean up numerous critics have challenged the conventional environmental kuznets curve both as a representation of what actually happens in the development process and as a policy prescription some pessimistic critics argue that crosssectional evidence for the environmental kuznets curve is nothing more than a

network structure and strategic investments an experimental analysis abstract this paper experimentally analyzes the effect of network structures on individuals decisions in a game of strategic substitutes the theoretical basis for our experiment is the model of bramoulle and kranton 2007 as predicted we find that individuals are able to coordinate on equilibria but that coordination strongly depends on the network structure despite frequent coordination failures in graphs of size n 4 equilibrium play seems easier on network architectures with high low density and low high centrality if play converges it almost exclusively does so towards the predicted equilibria theoretical results with respect to welfare are also confirmed next to global graph structural properties we also explore the effects of local and individual factors we find that behavior on networks is affected by the number of direct neighbors but not by individuals risk attitudes apparently the global and the local structure of a network does not leave much explanatory room for individual effects that pertain to risk taking

evaluating alternative representations of the choice sets in models of labour supply during the last two decades the discrete choice modelling of labour supply decisions has become increasingly popular starting with aaberge et al 1995 and van soest 1995 within the literature adopting this approach there are however two potentially important issues that are worthwhile analyzing in their implications and that so far have not been given the attention they might deserve a first issue concerns the procedure by which the discrete alternatives are selected to enter the choice set for example van soest 1995 chooses non probabilistically a set of fixed points identical for every individual this is by far the most widely adopted method by contrast aaberge et al 1995 adopt a sampling procedure suggested by mcfadden 1978 and also assume that the choice set may differ across the households a second issue concerns the availability of the alternatives most authors assume all the values of hours of work within some range 0 h are equally available at the other extreme some authors assume only two or three alternatives e g non participation part time and full time are available for everyone aaberge et al 1995 assume instead that not all the hour opportunities are equally available to everyone they specify a probability density function of opportunities for each individual and the discrete choice set used in the estimation is built by sampling from that individual specific density function in this paper we explore by simulation the implications of the procedure used to build the choice set fixed alternatives vs sampled alternatives accounting or not accounting for a different availability of alternatives the way the choice set is represented seems to have little impact on the fitting of observed values but a more significant and important impact on the out of sample prediction performance

learning by doing and learning from others human capital and technical change in agriculture household level panel data from a nationally representative sample of rural indian households describing the adoption and profitability of high yielding seed varieties hyvs associated with the green revolution are used to test the implications of a model incorporating learning by doing and learning spillovers the estimates indicate that i imperfect knowledge about the management of the new seeds was a significant barrier to adoption ii this barrier diminished as farmer experience with the new technologies increased iii own experience and neighbors experience with hyvs significantly increased hyv profitability and iv farmers do not fully incorporate the village returns to learning in making adoption decisions

labour supply incentives and recent family credit reforms in july i995 a fi o per week increment to family credit was introduced for recipients working full time this reform announced in the november i994 budget was a response to concerns that family credit created labour market inflexibility among those eligible for the benefit specifically it was designed to mitigate the effects of the high marginal withdrawal rates associated with the reduction of family credit as hours and gross income rise the secretary of state for social security stated

social hierarchies a laboratory study on punishment patterns across networks we experimentally study punishment patterns across network structures and their effect on cooperation in a repeated public goods setting subjects can only observe and punish their neighbors centralized structures like the star network outperform other incomplete networks and reach contribution levels like the ones observed in a complete network our results suggest that hierarchical network structures with a commonly observed player benefit more from sanctions not because central players punish more but because they follow and promote different punishment patterns while quasi central players in other incomplete architectures like the line network retaliate and get trapped in the vicious circle of antisocial punishment central players in the star network do not punish back increase their contributions when sanctioned by peripheral players and sanction other participants in a prosocial manner our results illustrate recent field studies on the evolutionary prevalence of hierarchical networks we document a network based rationale for this positive effect in an identity free fully anonymous environment jel c72 c91 c92 d90 h41

asymmetric network monitoring and punishment in public goods experiments abstract we extend the recent experimental literature on incomplete punishment networks in linear public goods games in these games we use an exogenous network to restrict both monitoring and the set of feasible punishment flows in addition to two baseline structures the complete network and the circle network we examine a novel asymmetric network in which both punishment responsibility and exposure differ across players average contributions are significantly lower in the asymmetric network driven entirely by the under monitored player who faces only one potential punisher we formulate and examine the hypothesis that asymmetry among a player s potential punishment targets may lead to discriminatory patterns of punishment in particular players might wish to punish targets for whom they are solely responsible discriminately more than targets for whom they share responsibility the experimental data do not support this hypothesis although they do suggest a compelling explanation as to why specifically we find that the under monitored player in the network retaliates against previous punishment significantly more often than others in the group which deters their only potential punisher from issuing stronger sanctions thus an additional complication of asymmetry in the network is that it may lead to more instances of anti social retaliation inhibiting the effectiveness of the decentralized punishment institution

does trade openness improve environmental quality the literature on trade openness economic development and the environment is largely inconclusive about the environmental consequences of trade this study treats trade and income as endogenous and estimates the overall impact of trade openness on environmental quality using the instrumental variables technique we find that whether or not trade has a beneficial effect on the environment varies depending on the pollutant and the country trade is found to benefit the environment in oecd countries it has detrimental effects however on sulfur dioxide so2 and carbon dioxide co2 emissions in non oecd countries although it does lower biochemical oxygen demand bod emissions in these countries we also find the impact is large in the long term after the dynamic adjustment process although it is small in the short term

the impact of growth energy and financial development on the environment in china a cointegration analysis this article aims to investigate the impact of financial development economic growth and energy consumption on environmental pollution in china from 1953 to 2006 using the autoregressive distributed lag ardl bounds testing procedure the main objective is to examine the long run equilibrium relationship between financial development and environmental pollution the results of the analysis reveal a negative sign for the coefficient of financial development suggesting that financial development in china has not taken place at the expense of environmental pollution on the contrary it is found that financial development has led to a decrease in environmental pollution it is concluded that carbon emissions are mainly determined by income energy consumption and trade openness in the long run moreover the findings confirm the existence of an environmental kuznets curve in the case of china

understanding china s urban pollution dynamics china s ongoing urban economic growth has sharply increased the population s per capita income lowered the count of people living below the poverty line and caused major environmental problems we survey the growing literature investigating the causes and consequences of china s urban pollution challenges we begin by studying how urban population and industrial growth impacts local pollution levels and greenhouse gas production as the urban population grows richer its demand for private transportation and electricity sharply increases such privately beneficial activity exacerbates urban pollution externalities facing these severe environmental challenges china s urbanites increasingly demand quality of life progress we survey the emerging literature investigating the demand for environmental progress in china progress in mitigating externalities hinges on whether the powerful central and local governments choose to address these issues we analyze the political economy of whether government officials have strong incentives to tackle lingering urban externalities we conclude by discussing future research opportunities at the intersection of environmental and urban economics jel o18 p25 p28 q53 r23 r41 r58

measuring strategic uncertainty in coordination games this paper proposes a method to measure strategic uncertainty by eliciting certainty equivalents analogous to measuring risk attitudes in lotteries we apply this method by conducting experiments on a class of one shot coordination games with strategic complementarities and choices between simple lotteries and sure payoff alternatives both framed in a similar way despite the multiplicity of equilibria in the coordination games aggregate behaviour is fairly predictable the pure or mixed nash equilibria cannot describe subjects behaviour we present two global games with private information about monetary payoffs and about risk aversion while previous literature treats the parameters of a global game as given we estimate them and show that both models describe observed behaviour well the global game selection for vanishing noise of private signals offers a good recommendation for actual players given the observed distribution of actions we also deduce subjective beliefs and compare them with objective probabilities

testing the pollution haven effect does the type of fdi matter many studies have tested the pollution haven effect phe which predicts that the tightening of local environmental regulations would shift foreign direct investment fdi to less regulated jurisdictions however most of them ignored the heterogeneity of fdi this paper studies the phe on local market oriented and export oriented fdi and tests whether the two types have different responsiveness to environmental regulations in a host country a simple model is developed to describe how different types of multinational companies respond in distinct ways to stricter environmental policies in host countries using us outward fdi data for 50 host countries and a survey measure of both the stringency and the enforcement of local environmental regulations i find a significant deterrent effect of local environmental regulations on inward fdi furthermore fdi in a host country is not only affected by local environmental regulations but also by environmental regulations in proximate countries more importantly accounting for the relative stringency of environmental regulations between a host country and the united states is critical for identifying a phe i find a significantly stronger effect of environmental policies on both types of fdi in host countries with environmental regulations that are stricter than those in the united states in these countries export oriented fdi also exhibits a greater sensitivity to local environmental regulations than local market oriented fdi

principles of network development and evolution an experimental study this paper reports on an experimental investigation of the evolution of networks and the individual decision making processes that guide it inasmuch as there is no history of experimental work on network formation part of the paper is devoted to the formulation of problems that can be examined experimentally the results are that networks composed of decentralized decision makers are capable of overcoming complex coordination and learning problems and converge to stationary when it does not occur significant and persistent inefficiencies can result the models of equilibration based on the principle of nash equilibrium are more reliable than models based on the alternative principles of efficiency seeking or focalness of the network configuration however individual decision making within networks is not in accordance with the simple decision rules of nash best response instead we observed complicated strategies that appear to trade short term profits in order to signal to and teach other agents the strategies required for long term profit maximization

information acquisition and exchange in social networks a central feature of social networks is information sharing the internet and related computing technologies shape the relative costs of private information acquisition and forming links with others this article presents an experiment on the effects of changing costs we find that a decline in relative costs of linking makes private investments more dispersed and gives rise to denser social networks aggregate investment falls but individuals access to investment remains stable due to increased networking the overall effect is an increase in individual utility and aggregate welfare

trade the pollution haven hypothesis and the environmental kuznets curve examining the linkages abstract this paper examines the extent to which the ekc inverted u relationship can be explained by trade and specifically the migration or displacement of dirty industries from the developed regions to the developing regions the pollution haven hypothesis phh using detailed data on north south trade flows for pollution intensive products the evidence for the phh is assessed emissions of 10 air and water pollutants are then estimated controlling for trade openness structural change and dirty north south trade flows evidence of pollution haven effects is found although such effects do not appear to be widespread and appear to be relatively small compared to the roles played other explanatory variables

structural models of family labor supply a discrete choice approach a static neoclassical structural model is presented explaining labor supply of both spouses in two adult households in the netherlands family preferences are described with a direct translog utility function with the husbands leisure the wifes leisure and family income as its arguments we assume that the choice set of each family is finite account is taken of the dutch tax and benefits system we allow for hours restrictions and random preferences and account for unobserved wages of nonworkers the models are estimated using smooth simulated maximum likelihood results based upon dutch cross section data from 1987 are illustrated by confidence intervals for elasticities and by several policy simulations excerpt

economic models for the environmental kuznets curve a survey abstract the environmental kuznets curve ekc refers to an inverted u shaped relationship between some pollutant level and per capita income i e the environmental quality deteriorates at early stages of economic growth and subsequently improves at a later stage since the early 1990s a considerable number of empirical studies have been conducted on the ekc and although there is no conclusive proof it has been recognized that the ekc emerges as an empirical regularity however some recent studies cast doubt on the concept and methodology of empirical results and evidence of the existence of the ekc has been questioned in fact how economic growth affects the environmental quality i e the shape of the ekc is still controversial in order to identify the actual relationship between the environmental quality and economic growth it is essential to develop economic models from various points of view this paper overviews the current stage of theoretical models that explain such relationship

environmental kuznets curve in china new evidence from dynamic panel analysis this paper applies a panel of 28 provinces of china from 1996 to 2012 to study the impacts of economic development energy consumption trade openness and urbanization on the carbon dioxide waste water and waste solid emissions by estimating a dynamic panel model with the system generalized method of moments gmm estimator and an autoregressive distributed lag ardl model with alternative panel estimators respectively we find that the environmental kuznets curve ekc hypothesis is well supported for all three major pollutant emissions in china across different models and estimation methods our study also confirms positive effects of energy consumption on various pollutant emissions in addition we find some evidence that trade and urbanization may deteriorate environmental quality in the long run albeit not in the short run from policy perspective our estimation results bode well for chinese government s goal of capping greenhouse emissions by 2030 as outlined in the recent china us climate accord while containing energy consumption and harm effects from expanding trade and urbanization remains some environmental challenges that china faces

the environmental kuznets curve cointegration and nonlinearity this paper clarifies some conceptual shortcomings of the empirical environmental kuznets curve ekc literature that arise because of the hitherto inadequate application of unit root and cointegration techniques the literature to date has ignored the fact and a fortiori the consequences that powers of integrated processes are themselves not integrated processes the paper explains why standard methods should not be applied and discusses some recently proposed viable estimation and testing approaches for cointegrating polynomial regressions the application to co2 and so2 emissions data shows that using appropriate methods leads to strongly reduced evidence for a cointegrating ekc compared to typical but conceptually not sound findings

economic growth trade and energy implications for the environmental kuznets curve abstract the environmental kuznets curve ekc hypothesis asserts that pollution follows an inverted u path with respect to economic growth the ekc has been explained in terms of structural changes in the composition of economic output and increased environmental regulation at higher income levels while some authors have incorporated the impact of trade policy orientation on the ekc the impact of the actual movement between countries of goods that embody pollution has not been considered this paper attempts to econometrically quantify the effect using pooled cross country and time series data the ekc hypothesis is examined with respect to commercial energy consumption the source of many serious environmental problems it was found that while both industrializing and industrialized countries have added to their energy requirements by exporting manufactured goods the growth has been substantially higher in the former at the same time industrialized countries have been able to reduce their energy requirements by importing manufactured goods exports of manufactured goods by industrialized countries has thus been an important factor in generating the upward sloping portion of the ekc and imports by industrialized countries have contributed to the downward slope

conventions and local interaction structures experimental evidence we present a series of experimental coordination games with a payoff dominant and a risk dominant nash equilibrium we examine in how far local interaction structures have effects on players strategy choices our three major observations are the following first local interaction with open neighborhoods along a circle leads to less coordination on the payoff dominant equilibrium than interaction in closed neighborhoods see also keser ehrhart and berninghaus economics letters 1998 second when players are allocated around a circle the neighborhood size has in the long run no effect on the players strategy choices third with the same neighborhood size players allocated on a lattice tend less than players allocated around a circle to coordinate on the payoff dominant equilibrium this is true although the players are given exactly the same instructions

the multinomial probit model revisited a discussion of parameter estimability identification and specification testing in this paper we examine the multinomial probit model in the light of recent developments in the field of simulation based inference we focus upon five broad areas specification of multinomial choice models parameter estimability and the use of simulation techniques parameter identification specification testing and practical issues in simulation based inference although the substitution of simulated probabilities for difficult to compute multidimensional integrals represents a significant step by examining the more tenuous task of identification and in particular the identification of covariance parameters we show how the specification and estimation of the multinomial probit still represents a formidable task

positional concerns and social network structure an experiment abstract we experimentally study the positional concerns of individuals embedded in social networks in the game individuals compete for positional advantage with their direct neighbors by purchasing a positional good the nash equilibrium consumption is determined by the katz bonacich centrality of the individual s network position while the efficient outcome requires a lower consumption level for most network positions the gameplay converged to the nash equilibrium except for local centers that consumed less of the positional good than the nash prediction despite this the consumption of the positional good increased in the individual s centrality the evolution of the gameplay was explained by the myopic best response dynamics model

environment kuznets curve for co2 emissions a cointegration analysis for china abstract this study examines the long run relationship between carbon emissions and energy consumption income and foreign trade in the case of china by employing time series data of 1975 2005 in particular the study aims at testing whether environmental kuznets curve ekc relationship between co 2 emissions and per capita real gdp holds in the long run or not auto regressive distributed lag ardl methodology is employed for empirical analysis a quadratic relationship between income and co 2 emission has been found for the sample period supporting ekc relationship the results of granger causality tests indicate one way causality runs through economic growth to co 2 emissions the results of this study also indicate that the carbon emissions are mainly determined by income and energy consumption in the long run trade has a positive but statistically insignificant impact on co 2 emissions

expectations network centrality and public good contributions experimental evidence from india do individuals in a position of social influence contribute more to public goods than their less connected partners can we motivate these influential individuals by disclosing how others expect them to act to answer these questions we play a public good game on a star network the experimental design is such that efficiency and equality considerations should motivate central players to contribute more than others using a subject population familiar with contributions to public goods on social networks we find that central players contribute just as much as the average of other players leading to a large loss of efficiency when we disclose the expectations of other players we find that central players often adjust their contributions to meet the expectations of the group expectations disclosure leads to higher contributions in groups that have weak social ties outside of the experiment in groups where ties are strong it has no significant effect this evidence casts doubt on the idea that individuals who by their social position can contribute more effectively to the public good rise to the challenge by contributing more than others in some but not all social groups these individuals can be motivated to increase contributions by disclosing the expectations of others

altruists egoists and hooligans in a local interaction model the authors study a population of agents each of whom can be an altruist or an egoist altruism is a strictly dominated strategy agents choose their actions by imitating others who earn high payoffs interactions between agents are local so that each agent affects and is affected by only his neighbors altruists can survive in such a world if they are grouped together so that the benefits of altruism are enjoyed primarily by other altruists who then earn relatively high payoffs and are imitated altruists continue to survive in the presence of mutations that continually introduce egoists into the population copyright 1998 by american economic association

scale technique and composition effects in trade related carbon emissions in china this study applies structural decomposition analysis to evaluate the scale composition and technique effects of trade related carbon emissions in china mainland from 1987 to 2007 the initial findings indicate that the increasing magnitude of china s trade both in terms of the carbon emissions embodied in exports and the carbon emissions avoided via imports had large scale effects during the whole period the technique effect caused by changes in input mix sector energy intensity fuel mix and carbon coefficients effectively offset part of the scale effect during the entire period but failed to do so during some sub periods changes in trade composition caused a relative small increase in the carbon emissions created by exports but a relative small decrease in the carbon emissions avoided via imports during the whole period

coordination and local interaction experimental evidence abstract subjects repeatedly played a three player coordination game with a payoff dominant and a risk dominant equilibrium subjects interacting in fixed groups quickly coordinated on the payoff dominant equilibrium while those interacting with their neighbors around a circle eventually coordinated on the risk dominant equilibrium

economic structure development policy and environmental quality an empirical analysis of environmental kuznets curves with chinese municipal data in many cases the relationship between environmental pollution and economic development can be generally depicted by an inverted u shaped curve or an environmental kuznets curve where pollution increases with income at the beginning and decreases after a certain level of income however what determine the shape of an enviornmental kuznets curve such as the height and the turning point of the curve have not been thoroughly studied a good understanding of the determinants is vitally important to the development community especially for the developing world where income growth is a high priority and yet environmental pollution also needs to be carefully controlled this study analyzes the impacts of economic structure development strategy and environmental regulation on the shape of the environmental kuznets curve with a city level panel dataset obtained from china the results show that economic structure development strategy and environmental regulation can all have important implications on the relationship between environmental environmental quality and economic development but the impacts can be different at different development stages

experimental games on networks underpinnings of behavior and equilibrium selection in this paper we describe a series of laboratory experiments that implement specific examples of a general network structure specifically actions are either strategic substitutes or strategic complements and participants have either complete or incomplete information about the structure of a random network since economic environments typically have a considerable degree of complementarity or substitutability this framework applies to a wide variety of settings we examine behavior and equilibrium selection the degree of equilibrium play is striking in particular with incomplete information behavior closely resembles the theoretical equilibrium whenever this is unique when there are multiple equilibria general features of networks such as connectivity clustering and the degree of the players help to predict informed behavior in the lab people appear to be strongly attracted to maximizing aggregate payoffs social efficiency but there are forces that moderate this attraction 1 people seem content with in the aggregate capturing only the lion s share of the efficient profits in exchange for reduced exposure to loss and 2 uncertainty about the network structure makes it considerably more difficult to coordinate on a demanding but efficient equilibrium that is typically implemented with complete information

the environmental kuznets curve does one size fit all abstract this paper uses a new panel data set on state level sulfur dioxide and nitrogen oxide emissions from 1929 1994 to test the appropriateness of the one size fits all reduced form regression approach commonly used in the environmental kuznets curve literature empirical results provide initial evidence that an inverted u shape characterizes the relationship between per capita emissions and per capita incomes at the state level parameter estimates suggest however that previous studies which restrict cross sections to undergo identical experiences over time may be presenting statistically biased results

is there an environmental kuznets curve for sulfur abstract most existing estimates of the environmental kuznets curve ekc for sulfur which use samples of mainly high income countries indicate a maximum emissions turning point at middle to lower high income levels of gdp per capita we use a larger and more globally representative sample than previous sulfur ekc studies we find that sulfur emissions per capita are a monotonic function of income per capita when we use a global sample and an inverted u shape function of income when we use a sample of high income countries a model estimated in first differences results in a monotonic ekc when estimated with both high income and global samples reductions in emissions are time related rather than income related

network effects on strategic interactions a laboratory approach abstract we examine the effect of interaction structure network on two classes of collective activities herding and shirking respectively referring to the situation where a player s incentive to take a certain action increases and decreases if more of her network neighbors follow the same action in our experiment we find that subjects do not act according to theoretical equilibrium and their frequencies of making the socially beneficial choice in herding and shirking games are inversely influenced by the number of network neighbors they have moreover the observed local network effect is stronger in shirking games while the global network effect is more significantly present in herding games we explain the behavioral regularities through a hybrid learning model which extends sewa learning into a network context as such our learning model provides a foundation for the observed dynamics disequilibrium behavior as well as the local and global network effects
