a solution concept for majority rule in dynamic settings we define and explore the notion of a dynamic condorcet winner dcw which extends the notion of a condorcet winner to dynamic settings we show that for every dcw every member of a large class of dynamic majoritarian games has an equivalent equilibrium and that other equilibria are not similarly portable across this class of games existence of dcws is guaranteed when members of the community are sufficiently patient we characterize sustainable and unsustainable outcomes study the effects of changes in the discount factor investigate efficiency properties and explore the potential for achieving renegotiation proof outcomes we apply this solution concept to a standard one dimensional choice problem wherein agents have single peaked preferences as well as to one involving the division of a fixed aggregate payoff

valuing the attributes of renewable energy investments increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries s strategies to achieve reductions in greenhouse gas emissions however renewable energy investments can often have external costs and benefits which need to be taken into account if socially optimal investments are to be made this paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in scotland a country which has set particularly ambitious targets for expanding renewable energy the external effects we consider are those on landscape quality wildlife and air quality we also consider the welfare implications of different investment strategies for employment and electricity prices the methodology used to do this is the choice experiment technique renewable technologies considered include hydro on shore and off shore wind power and biomass welfare changes for different combinations of impacts associated with different investment strategies are estimated we also test for differences in preferences towards these impacts between urban and rural communities and between high and low income households

protecting forests biodiversity and the climate predicting policy impact to improve policy choice p olicies must balance forest conservation s local costs with its benefits local to global in terms of biodiversity the mitigation of climate change and other eco services such as water quality the trade offs with development vary across forest locations we argue that considering location in three ways helps to predict policy impact and improve policy choice i policy impacts vary by location because baseline deforestation varies with characteristics market distances slopes soils etc of loca tions in a landscape ii different mixes of political economic pressures drive the location of different policies and iii policies can trigger second order or spillover effects likely to differ by location we provide empirical evidence that suggests the importance of all three considerations by reviewing high quality evaluations of the impact of conservation and development on forest impacts of well enforced conservation rise with private clearing pressure supporting i protection types e g federal state dif fer in locations and thus in impacts supporting ii differences in development process explain differ ent signs for spillovers supporting iii

political competition between differentiated candidates abstract we introduce a framework of electoral competition in which voters have general preferences over candidates immutable characteristics such as gender race or previously committed policy positions as well as their policy positions which are flexible candidates are uncertain about the distribution of voter preferences and choose policy positions to maximize their winning probability we characterize a property of voter utility functions uniform candidate ranking ucr that captures a form of separability between fixed characteristics and policy when voters have ucr preferences candidates equilibrium policies converge in any strict equilibrium in contrast notions like competence or complementarity lead to non ucr preferences and policy divergence in particular we introduce a new class of models that contains the probabilistic voting model as a special case and in which there is a unique equilibrium that generically features policy divergence

impact evaluation of forest conservation programs benefit cost analysis without the economics economists are increasingly using impact evaluation methods to measure the effectiveness of forest conservation programs theoretical analysis of two complementary economic models demonstrates that the average treatment effect on the treated att typically reported by these studies can be related to an economic measure of program performance only under very restrictive conditions this is because the att is usually expressed in purely physical terms e g avoided deforestation and ignores heterogeneity in the costs and benefits of conservation programs for the same reasons clinical trials are a misleading analogy for the evaluation of conservation programs to be more useful for economic analyses of conservation programs impact evaluations should work toward developing measures of program outcomes that are economically more relevant data that would enable the evaluation of impacts on forest degradation not just deforestation and primary forests not forests in general better estimates of spatially disaggregated treatment effects not program wide averages and better information on the accuracy of estimated treatment effects as predictors of future risks

consumer demand for green power and energy efficiency abstract this article examines reported willingness to pay for electric utility investments in renewable energy and energy efficiency resources using the results of deliberative polls conducted by electric utilities in texas 1 age education and salary tend to affect reported willingness to pay for utility investments in these resources intensive exposure to information about energy resource issues led to an increase in the number of respondents interested in paying a modest premium to support investments in both renewable energy resources and energy efficiency however average reported premiums actually declined following the polls as very high outlier responses moved to more reasonable values following the polls these results support the contention that informed dialogue about energy alternatives will result in broader interest in providing a modest level of support for these resources

fertilizer adoption by smallholders in the brazilian amazon farm level evidence multiple constraints prevent smallholders from adopting fertilizers even with regional supply of agricultural inputs expanding and soils being weared out using comprehensive farm level data from the eastern brazilian amazon we found that market proximity had a significant positive correlation with fertilizer adoption even after controlling for liquidity land tenure education experience and access to rural extension services nevertheless few smallholders completely replaced nutrients from vegetation with fertilizers instead we found that a hybrid system that combines nutrients from vegetation and fertilizers was approximately twice as common as exclusive fertilizer use we suggest that the option for this diversified nutrient portfolio may result not only from a lack of capital or knowledge regarding return on fertilizer use but also from the need to adapt to the economic constraints facing smallholders and minimize risk results indicate that a rural extension program aimed at supporting a rapid and complete replacement of ashes from vegetation by fertilizers could prove unsuccessful for amazonian smallholders

social ideology and taxes in a differentiated candidates framework many observers argue that political polarization particularly on social and cultural issues has increased in the united states how does this influence the political competition on economic issues we analyze this question using a framework in which two officemotivated candidates differ in their fixed ideological position and choose a level of government spending to maximize their vote share in equilibrium candidates cater to a set of swing voters who contain socially conservative and economically liberal voters as well as socially liberal and economically conservative voters we analyze how voters cultural preferences and candidates cultural positions influence equilibrium economic positions jel d72 e62 h50 z13 many observers have argued that polarization between the two major parties in the united states particularly on noneconomic cultural matters has increased this is reflected both at the elite level in particular in congress poole and rosenthal 1984 1985 2000 and among democratic and republican activists and voters abramowitz and saunders 2008 harbridge and malhotra 2011 in the american national election survey respondents report their own ideological position on a scale from 1 very liberal to 7 very conservative the number of respondents who report one of the extreme positions 1 2 6 or 7 has grown from 20 and 21 percent in 1972 and 1976 to 31 and 30 percent in the 2004 and 2008 respectively moreover liberal and conservative voters have become considerably more reliable supporters of democrats and republicans respectively over the last generation 1 if we accept the widespread view that reagan s conservative revolution has created a cultural wedge between the parties that only widened in the 1990s and 2000s what consequences for the parties economic policies should we expect

background inequality and differential participation in deliberative valuation lessons from small group discussions on forest conservation in colombia abstract deliberative monetary valuation dmv methods have been proposed as a more democratic alternative to traditional contingent valuation methods cvm for natural resource decision making these deliberative methods are subject to criticisms one issue of concern is that the socio economic inequalities among members of the deliberative group may severely impede communication and consequently distort deliberative outcomes to examine such possibility we applied the deliberative methodology in a case study of forest conservation in colombia we found that those individuals who assumed social environmental leadership positions tended to dominate group discussion nevertheless the variations in the capacity to engage in group deliberation were better explained by participants personal characteristics than external constraints or group pressure also there was little evidence that leadership and domination in group deliberation significantly influenced participants stated wtp we conclude that dmv is vulnerable to the background inequalities among group members the democratic potential of deliberative methods should be critically examined in terms of the capacity to communicate effectively and equally

community perspectives of wind energy in australia the application of a justice and community fairness framework to increase social acceptance decisions concerning the siting of infrastructure developments or the use of natural resources have the potential to damage a community s social well being if the outcomes are perceived to be unfair justice is accepted as central to the well functioning of society with fairness being an expectation in day to day interactions outcomes that are perceived to be unfair can result in protests damaged relationships and divided communities particularly when decisions are made which benefit some sections of the community at the perceived expense of others through empirical research using a wind farm pilot study community perceptions of a community consultation process are explored using procedural justice principles to evaluate fairness findings from the pilot study indicate that perceptions of fairness do influence how people perceive the legitimacy of the outcome and that a fairer process will increase acceptance of the outcome a key research finding was that different sections of a community are likely to be influenced by different aspects of justice namely by outcome fairness outcome favourability and process fairness based on this finding a community fairness framework was developed which has potential application in community consultation to increase social acceptance of the outcome

aggregation and social choice a mean voter theorem a celebrated result of black 1948a demonstrates the existence of a simple majority winner when preferences are single peaked the social choice follows the preferences of the median voter the median voter s most preferred outcome beats any alternative however this conclusion does not extend to elections in which candidates differ in more than one dimension this paper provides a multi dimensional analog of the median voter result we provide conditions under which the mean voter s most preferred outcome is unbeatable according to a 64 majority rule the conditions supporting this result represent a significant generalization of caplin and nalebuff 1988 the proof of our mean voter result uses a mathematical aggregation theorem due to prekopa 1971 1973 and borell 1975 this theorem has broad applications in economics an application to the distribution of income is described at the end of this paper results on imperfect competition are presented in the companion paper caplin and nalebuff 1991

wind power implementation the nature of public attitudes equity and fairness instead of backyard motives abstract public attitudes anywhere in europe show moderate to strong support for the implementation of renewable energy nevertheless planning wind power developments appears to be a complicated matter in most countries the problems that have to be dealt with during decision making processes on the siting of wind turbines are usually referred to as mere communication problems however public attitudes towards wind power are fundamentally different from attitudes towards wind farms this gap causes misunderstandings about the nature of public support for renewables in particular where planners easily assume support for renewables can be generated by information campaigns emphasising the environmental benefits whereas opposition to renewable energy schemes can be explained by a selfish not in my backyard attitude both explanations used by planners authorities and unfortunately by many scholars are falsified furthermore policies that still take this common knowledge for granted can have negative consequences for the implementation rates of renewables visual evaluation of the impact of wind power on landscape values is by far the dominant factor in explaining why some are opposed to wind power and others are supporting it moreover feelings about equity and fairness appear the determinants of backyard motives instead of selfishness

render unto caesar taxes charity and political islam abstract using an original nationally representative survey of 600 tunisians we show that support for the islamic party in the first post arab spring election came from wealthier districts and individuals we demonstrate that standard public finance arguments explain this voting pattern better than other available explanations our model predicts that a voter s probability of voting for a religious party i increases with income for the poorest voters but possibly decreases with income for the richest ii is greater for voters in richer districts and iii increases with the voter s religiosity our empirical results align with our predictions and suggest that individual and district wealth were key drivers of support for the islamic party we test for other possible factors affecting voting such as economic disgruntlement migration access to media or attitudes towards gender parity or towards the west finally we document similar patterns in other key elections in the muslim world

shale gas policy in the united kingdom an argumentative discourse analysis shale gas has become an energy policy priority in the united kingdom in light of profitable extraction activities in the united states since 2012 the coalition government has created key economic drivers to encourage shale exploration whilst growing activism in affected site communities has stirred significant media and academic commentary this study examines the growing national debate as a matter of discourse adopting an argumentative discourse analytic approach to assess data collected from stakeholder interviews n 21 and key policy actor statements quoted in broadsheet newspapers we explore three dominant storylines emerging in relation to shale gas policy 1 cleanliness and dirt concerns the relative framing of the environmental benefits and harms of shale gas 2 energy transitions pathways and diversions concerns geographic metaphors of transitions to carbon intensive and low carbon energy systems and 3 geographies of environmental justice concerns divisions of economic benefit distribution environmental impact and procedural fairness we find that central government policy rhetoric emphasises economic development regulatory oversight and distribution of benefits to site communities whilst minimising discussion of the implications of shale gas for anthropogenic climate change the role of these discourses in influencing shale gas policy is discussed

exploring participatory energy budgeting as a policy instrument to foster energy justice abstract the ethical and sustainable production and consumption of energy are becoming increasingly important with the ongoing transformation and decentralization of the energy system for other kinds of goods and commodities ethical consumption have direct implications for and the participation of informed citizens due to its intangibility energy lacks the same levels of reflection and intervention by citizens and those aspects are yet to be fully explored in practice this paper contributes to the understanding of how energy justice might be approached we reflect on an empirical experience of participatory energy budgeting a process aimed at determining how to redistribute a share of energy linked to collective virtuous consumption behaviors we analyze through a qualitative thematic analysis how participants make sense of the participatory energy budgeting process and the emerged dynamics within the local communities and how this process can strive to reconfigure the relationship among civil society the energy sector and politics in order to remediate injustices we highlight how the construction in practice of energy justice in a local community might be closely linked to issues such as the form of energy governance that allows for the participation of citizens and the accountability of the process policies and technological limitations

nimby or not exploring the relevance of location and the politics of voiced opinions in renewable energy siting controversies local protests against renewable energy facilities have added fuel to the debate about the so called nimby not in my back yard effect this paper identifies six variables that can hamper the comparison between different public perception studies and offers two broad conclusions on aggregate proximity does have strong influence on public attitudes to proposed projects but the nature strength and spatial scale of this effect may vary according to local context and value of the land residents of stigmatised places are more likely to welcome facilities that are relatively green while people who derive a more positive sense of identity from particular rural landscapes are likely to resist such potential developments especially if they also live there secondly the fear of being branded a nimby and the positive ethics associated with the notion of renewable are both likely to colour the responses of many interviewees these aspects need to be clarified and accounted for in analyses of elicited responses both quantitative and qualitative if we are to improve our understanding of the social construction of individual attitudes in siting conflicts

protected areas local governments and strategic interactions the case of the icms ecologico in the brazilian state of parana various conservation initiatives have been implemented in developing countries with increasing involvement on the part of local governments a concern in entrusting decisions to local governments is that the effectiveness of the conservation instrument can be threatened by interactions among these local governments we examine this concern with respect to an ecological fiscal transfer mechanism the icms ecologico implemented in brazil in the early 1990 s in order to reduce biodiversity loss the mechanism enables states to reward municipalities for the creation and management of protected areas we describe this mechanism present a conceptual framework aimed at understanding the potential sources and consequences of interactions among local governments on the effectiveness of a decentralized mechanism aimed at promoting the creation of protected areas and propose an empirical application using a bayesian spatial tobit model our empirical investigation on the creation of protected areas in the state of parana between 2000 and 2010 reveals strategic substitutability in municipalities conservation decisions this finding also leads us to discuss the issue of identification of a negative spatial lag coefficient when there is a positive spatial error correlation

a model of political equilibrium in a representative democracy abstract this paper studies political equilibrium in a two party representative democracy in which the political parties are policy motivated and voters trade off their policy preferences against their party identity it is shown that the parties will in general adopt differing policy positions in equilibrium and that under certain qualifications the winning policy will lie between the more popular party s preferred policy and a certain utilitarian optimum the winning policy will be closer to this utilitarian optimum the less biased the electorate is in terms of party identification

wind farm externalities and public preferences for community consultation in ireland a discrete choice experiments approach abstract in ireland the deployment of onshore wind turbines has become progressively more difficult in some areas because of the potential negative externalities associated with their operation using a discrete choice experiment dce we employ a willingness to accept framework to estimate the external effects of wind turbines on local residents with the inclusion of community consultation and to quantify the compensation required to permit wind farms to be built in ireland our findings reveal that the majority of respondents are willing to make monetary tradeoffs to allow for wind power initiatives and we find that respondents require less compensation if provision is made for a community representative and setback distance is increased

the binary policy model abstract we introduce a model of electoral competition with office motivated candidates who are exogenously committed to particular positions on some issues while they choose positions for the remaining issues a position is majority efficient if a candidate cannot make a majority of the electorate better off given his fixed positions we characterize existence conditions for majority efficient positions the candidates fixed positions in our framework imply that only some voters are swing voters and we analyze how the distribution of swing voters determines whether candidates choose majority efficient positions we also analyze plurality and runoff elections with multiple candidates in our framework

balanced budget redistribution as the outcome of political competition this paper models balanced budget redistribution between socio economic groups as the outcome of electoral competition between two political parties equilibrium is unique in the present model and a sufficient condition for existence is given requiring that there be enough stochastic heterogeneity with respect to party preferences in the electorate the validity of hotelling s principle of minimum differentiation and of director s law are examined under alternative hypotheses concerning administrative costs of redistributions and voter s possibilities both of abstaining from voting and of becoming campaign activists for one of the parties the policy strategy of expected plurality maximization is contrasted with the strategy of maximizing the probability of gaining a plurality incomes are fixed and known so lump sum taxation is feasible however constraints on tax transfer differentiation between individuals are permitted in the analysis

crime and social interactions the high variance of crime rates across time and space is one of the oldest puzzles in the social sciences this variance appears too high to be explained by changes in the exogenous costs and benefits of crime we present a model where social interactions create enough covariance across individuals to explain the high cross city variance of crime rates this model provides an index of social interactions which suggests that the amount of social interactions is highest in petty crimes moderate in more serious crimes and almost negligible in murder and rape

nuclear power climate change and energy security exploring british public attitudes public attitudes towards nuclear power in the uk have historically been deeply divided but as concern about climate change and energy security has exerted an increasing influence on british energy policy nuclear power has been reframed as a low carbon technology previous research has suggested that a significant proportion of people may reluctantly accept nuclear power as a means of addressing the greater threat of climate change drawing on the results of a national british survey n 1822 the current study found that attitudes towards nuclear remain divided with only a minority expressing unconditional acceptance in general people who expressed greater concern about climate change and energy security and possessed higher environmental values were less likely to favour nuclear power however when nuclear power was given an explicit reluctant acceptance framing allowing people to express their dislike for nuclear power alongside their conditional support concerns about climate change and energy security became positive predictors of support for nuclear power these findings suggest that concern about climate change and energy security will only increase acceptance of nuclear power under limited circumstances specifically once other preferred options have been exhausted

temporal and spatial modelling of tropical deforestation a survival analysis linking satellite and household survey data we estimate a spatially explicit model of the forest clearance process among smallholder farmers in an agricultural frontier of southern mexico our analysis takes as its point of departure a simple utility maximising model that suggests many possible determinants of deforestation in an economic environment characterised by missing or thin markets hypotheses from the model are tested on a data set that combines a time series of satellite imagery with data collected from a survey of farm households whose agricultural plots were geo referenced using a global positioning system gps we implement a survival analysis to identify the effect of household level explanatory variables on the probability of deforestation this approach allows us to introduce a measure of the time until clearance as a covariate thereby affording a control for the effect of potentially important explanatory variables that vary through time but are not directly observable in addition to identifying several variables relevant for policy analysis including household demographics proximity to roads and government provision of agricultural support model results suggest that the deforestation process is characterised by non linear duration dependence with the probability of forest clearance first decreasing and then increasing with the passage of time

the interaction of population growth and environmental quality an important question for policy is whether holding constant per capita income and other relevant factors population pressures have a significant effect upon environmental degradation the authors examine the effect of population pressures upon deforestation in 64 developing countries in an attempt to provide relevant empirical findings data on deforestation were drawn from the food and agriculture organizations production yearbook results suggest that a relationship exists between per capita income and deforestation and that for africa rural population density shifts the relationship upward the increase in the rate of deforestation levels off as income increases the rate of growth in per capita income also has a significant negative impact upon deforestation although the magnitude of the effect is small the authors close in stressing that reducing the rate of population growth is not necessarily the best way to reduce the rate of deforestation deforestation in developing countries is really a problem of market failure since property rights are often neither defined nor enforced there is essentially no private cost of deforestation with no long term stake in the land people have no incentive to use land efficiently this situation must be addressed in conjunction with the problems of poverty and population growth

social acceptance of renewable energy innovation an introduction to the concept this paper introduces the special issue on social acceptance of renewable energy innovation it is a collection of best papers presented at an international research conference held in tramelan switzerland in february 2006 while there are ambitious government targets to increase the share of renewable energy in many countries it is increasingly recognized that social acceptance may be a constraining factor in achieving this target this is particularly apparent in the case of wind energy which has become a subject of contested debates in several countries largely due to its visual impact on landscapes this paper introduces three dimensions of social acceptance namely socio political community and market acceptance factors influencing socio political and community acceptance are increasingly recognized as being important for understanding the apparent contradictions between general public support for renewable energy innovation and the difficult realization of specific projects the third dimension market acceptance has received less attention so far and provides opportunities for further research particularly from management scholars

contagious development neighbor interactions in deforestation article i nfo we estimate neighbor interactions in deforestation in costa rica to address simultaneity and the presence of spatially correlated unobservables we measure for neighbors deforestation using the slopes of neighbors and neighbors neighbors parcels we find that neighboring deforestation significantly raises the probability of deforestation policies for agricultural development or forest conservation in one area will affect deforestation rates in non targeted neighboring areas correct estimation of the interaction reverses the naive estimate s prediction of multiple equilibria

discrete choice with social interactions this paper provides an analysis of aggregate behavioural outcomes when individual utility exhibits social interaction effects we study generalized logistic models of individual choice which incorporate terms reflecting the desire of individuals to conform to the behaviour of others in an environment of noncooperative decisionmaking laws of large numbers are generated in such environments multiplicity of equilibria in these models which are equivalent to the existence of multiple self consistent means for average choice behaviour will exist when the social interactions exceed a particular threshold local stability of these multiple equilibria is also studied the properties of the noncooperative economy are contrasted with the properties of an economy in which a social planner determines the set of individual choices finally a likelihood function based on the theoretical model is given and conditions for the econometric identifiability of the model are established

deforestation in the amazon a unified framework for estimation and policy analysis deforestation is a matter of pressing global concern yet surprisingly little is known about the relative efficacy of various policies designed to combat it this article sets out a framework for measuring the cost effectiveness of alternative policies both command and control and incentive based in the brazilian amazon first i estimate the demand for deforestation on private properties exploiting regional variation in transportation costs as a means to recover farmers responses to permanent policies here rescaling transportation costs using local yields allows me to express changes in farmers valuations in dollars per hectare i then use the estimated demand to infer farmers willingness to deforest under different counterfactual policies such as payments to avoid deforestation and taxes on land use along with the corresponding potential farmers lost surpluses the results indicate that payment programmes and land use taxes on agricultural land can be highly effective in preserving the rainforest and also be substantially less expensive than command and control policies approximately 8 times less costly a carbon tax equal to the social cost of carbon could virtually eliminate all agricultural land in the amazon given the low agricultural returns there

unintended impacts of public investments on private decisions the depletion of forested wetlands by affecting relative economic returns infrastructure investments can induce major changes in private land use the authors find that 30 percent of forested wetland depletion in the mississippi valley has resulted from private decisions induced by federal flood control projects despite explicit federal policy to preserve wetlands the model aggregates individual land use decisions using a parametric distribution of unobserved land quality dynamic simulations are used to quantify the impacts on wetlands of federal projects and other factors copyright 1990 by american economic association

public attitudes regarding large scale solar energy development in the u s abstract using data collected from both a national sample as well as an oversample in u s southwest we examine public attitudes toward the construction of utility scale solar facilities in the u s as well as development in one s own county our multivariate analyses assess demographic and socio psychological factors as well as context in terms of proximity of proposed project by considering the effect of predictors for respondents living in the southwest versus those from a national sample we find that the predictors and impact of the predictors related to support and opposition to solar development vary in terms of psychological and physical distance overall for respondents living in the u s southwest we find that environmentalism belief that developers receive too many incentives and trust in project developers to be significantly related to support and opposition to solar development in general when southwest respondents consider large scale solar development in their county the influence of these variables changes so that property value race and age only yield influence differential effects occur for respondents of our national sample we believe our findings to be relevant for those outside the u s due to the considerable growth pv solar has experienced in the last decade especially in china japan germany and the u s

equilibrium in multicandidate probabilistic spatial voting this paper presents a multicandidate spatial model of probabilistic voting in which voter utility functions contain a random element specific to each candidate the model assumes no abstentions sincere voting and the maximization of expected vote by each candidate we derive a sufficient condition for concavity of the candidate expected vote function with which the existence of equilibrium is related to the degree of voter uncertainty we show that under concavity convergent equilibrium exists at a minimum sum point at which total distances from all voter ideal points are minimized we then discuss the location of convergent equilibrium for various measures of distance in our examples computer analysis indicates that non convergent equilibria are only locally stable and disappear as voter uncertainty increases

the inclusion of social aspects in power planning a b s t r a c t this paper overviews previous research addressing the inclusion of the social dimension of sustainable development on power systems planning consequences of the recent energy policies and strategies are already being felt in developed countries power systems with the integration of rising quotas in renewable energy technologies however while the tools that aid decision making on power planning show that economic and environmental issues are easily quantifiable and thus modeled social concerns have been addressed in a less extensive and more subjective way implying in most cases expert participation on multi criteria decision aid techniques a survey of recent papers providing public perceptions on electricity generation technologies and projects is presented these papers were chosen and reviewed in order to present a representative array of methodologies that are used to assess social acceptance of technologies according to some of the reviewed papers this issue is suggested to be fundamental to increase project success as a conclusion stands the fact that further discussion is still needed in order to achieve solid agreement among experts over what are the positive and the negative drivers to social sustainability otherwise models will not be able to translate reality and improve it under this point of view

social choice and electoral competition in the general spatial model this paper extends the theory of the core the uncovered set and the related undominated set to a general set of alternatives and an arbitrary measure space of voters we investigate the properties of social preferences generated by simple games we extend results on generic emptiness of the core we prove the general nonemptiness of the uncovered and undominated sets and we prove the upper hemicontinuity of these correspondences when the voters preferences are such that the core is nonempty and externally stable finally we give conditions under which the undominated set is lower hemicontinuous

efficiency equity tradeoffs in targeting payments for ecosystem services this article develops an analytic framework to analyze the tradeoff between economic efficiency and distributional equity in targeting payments for ecosystem services pes it also proposes an empirical procedure to trace out the efficiency equity frontier where the program is pareto optimal in the sense that it cannot be improved upon to achieve either higher efficiency or distributional equity without compromising the other we apply the procedure to the conservation reserve program crp the largest pes program in u s history to analyze a whether it is possible to improve both the efficiency and the distributional equity of the program and b what the choice made by crp administrators implies about the political economic balance results reveal that a crp administrators forfeited about 9 of efficiency for an 18 23 improvement in distributional equity depending on the equity indicator used in the eighteenth signup of the crp b reducing the maximum allowable rental rate for all contracts would improve efficiency at the cost of distributional equity c reducing the maximum county enrollment cap would reduce efficiency without generating much improvement in distributional equity and d the crp targeting criterion could be redesigned to achieve both higher efficiency and higher distributional equity

landscape preferences and patterns of residential development abstract i analyze a model of residential location choice where people derive utility from their proximity to open space when people have such landscape preferences then 1 equilibrium residential development is mixed with undeveloped land 2 equilibrium land price gradients depend sensitively on how land markets are organized are not generally monotonic and may or may not reflect the value of open space and 3 dynamic equilibria generally have the property that more remote areas are developed before more central areas finally when compared to optimal development equilibrium development houses too many residents too close together and remote areas are developed too soon these results imply that equilibrium development may not be sprawling enough and that policies to encourage infill development are not welfare improving

keep it local and fish friendly social acceptance of hydropower projects in switzerland hydropower is the largest source of renewable electricity in the world but despite being a mature and clean energy technology it has also been the subject of ecological and social conflict literature suggests that the social acceptance of renewable energy can be increased by respecting procedural justice fair participatory planning processes and distributional justice fairly allocating costs and benefits however empirical evidence about how justice considerations are related to the expansion of hydropower is scarce pre existing studies being mostly qualitative in nature we contribute to filling the gap in the current literature by describing in this paper how choice experiments with 1004 swiss residents were undertaken to explore the influence of procedural and distributional justice on acceptance relative to other attributes of hydropower projects we find that while considerations about justice do play a role in decisions to accept respondents in switzerland care most about ecological impacts and secondly about local ownership

does green consumerism increase the acceptance of wind power abstract in this paper we discuss what might be termed an action based learning approach to promoting important pro environmental actions such as support for or acceptance of environmental policy such an approach involves promoting simple and easy behaviours as entry points for more radical steps towards sustainability referred to as catalytic or wedge behaviours despite the obvious need for innovative approaches to promote important pro environmental behaviour and sound theoretical backing for such concepts there is a lack of research testing the key propositions of this approach in a survey study based on a random sample of residents of the state of maine usa we find that both everyday green behaviour and the acceptance of an expansion of wind power are rooted in environmental concern and that everyday green behaviour gives a significant contribution to predicting acceptance of wind power when controlling for environmental concern hence the promotion of everyday green behaviours may prepare the grounds for increasing acceptance of more far reaching changes in the population such as an expansion of wind power

contagious cooperation temptation and ecosystem collapse real world observations suggest that social norms o f cooperation can be effective in overcoming social dilemmas such as the joint management of a c ommon pool resource but also that they can be subject to slow erosion and sudden collapse we show that these patterns of erosion and 15 collapse emerge endogenously in a model of a closed community harvesting a renewable natural resource in which individual agents face the tempta tion to overexploit the resource while a cooperative harvesting norm spreads through the community via interpersonal relations we analyze under what circumstances small changes in key parameters including the size of the community and the rate of technological progress trigger catastrophic transitions from 20 relatively high levels of cooperation to widespread norm violation causing the social ecological system to collapse

multidimensional electoral competition between differentiated candidates it is known that multidimensional downsian competition fails to admit an equilibrium in pure strategies unless very stringent conditions on the distribution of voters bliss points are imposed plott 1967 this paper revisits this problem considering that the two vote share maximizing candidates are dierentiated that is candidates strategically decide po sitions only in some of the n dimensions while in the rest their positions are assumed to be xed these xed dimensions may be viewed as candidates immutable characteristics race religion culture etc we nd that if candidates are su ciently dierentiated if in the xed dimensions their positions are su ciently dierent then a unique nash equilibrium in pure strategies is guaranteed to exist for any distribution of voters bliss points perhaps more importantly we show that this is true even if there exists a unique xed dimension and candidates instrumentally decide their positions in all other n 1 dimensions

the mean voter theorem necessary and sufficient conditions for convergent equilibrium formal models of elections have emphasized the convergence of party leaders towards the centre of the electoral distribution this paper attempts to resolve the apparent disparity between the formal result and the perception of political divergence by considering a model incorporating valence valence can be interpreted as the non policy basis of political judgement made by the electorate concerning the quality of political contenders the theorem presented here shows that there is a necessary condition for convergence the condition involves the difference in party valences and the electoral variance when the condition fails the low valence parties will be forced to adopt policy positions far from the electoral centre the inference appears to be substantiated by an empirical model of the israel election in 1996 copyright 2007 wiley blackwell

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

is small beautiful a multicriteria assessment of small scale energy technology applications in local governments in its 2003 white paper the uk government set ambitious renewable energy targets local governments and households have an increasing role in the overall energy system as consumers suppliers of smaller scale applications and citizens discussing energy projects in this paper we consider if small scale or large scale approaches to renewable energy provision can achieve energy targets in the most socially economically and environmentally see effective way we take a local case study of renewable energy provision in the metropolitan borough of kirklees in yorkshire uk and apply a multi criteria decision analysis methodology to compare the small scale schemes implemented in kirklees with large scale alternatives the results indicate that small scale schemes are the most see effective despite large scale schemes being more financially viable the selection of the criteria on which the alternatives are assessed and the assigned weights for each criterion are of crucial importance it is thus very important to include the relevant stakeholders to elicit this information

networks in the modern economy mexican migrants in the u s labor market this paper attempts to identify job networks among mexican migrants in the u s labor market the empirical analysis uses data on migration patterns and labor market outcomes based on a sample of individuals belonging to multiple origin communities in mexico over a long period of time each community s network is measured by the proportion of the sampled individuals who are located at the destination the united states in any year we verify that the same individual is more likely to be employed and to hold a higher paying nonagricultural job when his network is exogenously larger by including individual fixed effects in the employment and occupation regressions and by using rainfall in the origin community as an instrument for the size of the network at the destination

can intensification of cattle ranching reduce deforestation in the amazon insights from an agent based social ecological model abstract deforestation in the amazon with its vast consequences for the ecosystem and climate is largely related to subsequent land use for cattle ranching in addition to conservation policies proposals to reduce deforestation include measures to intensify cattle ranching however the effects of land use intensification on deforestation are debated in the literature this paper introduces the abacra model a stylized agent based model to study the interplay of deforestation and the intensification of cattle ranching in the brazilian amazon the model combines social learning and ecological processes with market dynamics in the model agents adopt either an extensive or semi intensive strategy of cattle ranching based on the success of their neighbors they earn their income by selling cattle on a stylized market we present a comprehensive analysis of the model with statistical methods and find that it produces highly non linear transient outcomes in dependence on key parameters like the rate of social interaction and elasticity of the cattle price we show that under many environmental and economic conditions intensification does not reduce deforestation rates and sometimes even has a detrimental effect on deforestation anti deforestation policies incentivizing fast intensification can only lower deforestation rates under conditions in which the local cattle market saturates

rural versus urban preferences for renewable energy developments development of renewable energy resources such as wind farms and hydro electric schemes are being promoted as a new method of expanding and diversifying employment in rural areas however such energy projects are associated with a range of environmental impacts which might be detrimental to other economic activities such as those based on nature tourism the authors use a choice experiment to quantify peoples preferences over environmental and employment impacts that may result from the deployment of renewable energy projects in rural areas of scotland focussing in particular on any differences between the preferences of urban and rural dwellers and on heterogeneity within these groups rural and urban households are shown to have different welfare gains which are dependent on the type of renewable energy technology and on the scale of project under consideration
