dynamic coalition formation and the core this paper presents a dynamic model of endogenous coalition formation in cooperative games with transferable utility tu the players are boundedly rational at each time step a player decides which of the existing coalitions to join and demands a payoff these decisions are determined by a best reply rule given the coalition structure and allocation in the previous period further the players experiment with myopically suboptimal strategies whenever there are potential gains from trade we establish an isomorphism between the set of absorbing states of the process and the set of core allocations and show that the process converges to one of these states with probability one whenever the core is non empty these results do not require superadditivity of the characteristic function and they carry over to the case of coalitional values depending on the coalition structure and to non transferable utility ntu games

determinants of pro environmental consumption the role of reference groups and routine behavior abstract this paper investigates the determinants of pro environmental consumption focusing on the role of reference groups and routine behavior we study the factors that explain whether or not people have installed residential solar energy equipment or have subscribed to green electricity programs and the factors that influence the intensity of buying organic food in addition to demographic characteristics and environmental attitudes we consider the following categories of determinants economic and cognitive factors income estimated price premium level of information on environmentally friendly goods consumption patterns of reference persons own consumption patterns in the past using a unique data set from a survey conducted in the region of hanover germany we find the following 1 economic and cognitive factors are significant covariates of all three kinds of pro environmental consumption their influence is greatest in the case of green electricity 2 consumption patterns of reference persons are significant covariates of all three kinds of pro environmental consumption their influence is greatest in the case of organic food 3 the intensity of buying organic food is greater the longer people have been consumers of these goods

a prospect theory nash bargaining solution and its stochastic stability abstract we consider the long run outcomes of bargaining games when players obey prospect theory we extend the evolutionary bargaining model of young 1993 to a two stage nash demand game two players simultaneously choose whether to exercise an outside option in the first stage and play the nash demand game in the second stage which will be reached only if neither player exercises the outside option we address the influence on the stochastically stable division of reference dependent preferences where the reference point is the value of the outside option we show that the division consistently differs from the nash bargaining solution under expected utility theory inspired by this we propose a prospect theory nash bargaining solution which coincides with the stochastically stable division

consumers preferences for fresh broccolis interactive effects between country of origin and organic labels while international trade in organic products has grown significantly understanding consumers preferences for imported organic foods has remained limited this research examines the impact of country of origin labeling on us consumers choices of organic foods results show that consumer valuation of domestically produced organic broccoli was significantly higher than that of imported organic broccoli adding information about usda organic certification standards rules for imported products mildly increases consumer valuation of imported organic broccoli in some cases these findings suggest that providing such information may have a positive impact on consumer willingness to purchase imported organic products

using choice experiments to estimate consumer valuation the role of experimental design and attribute information loads with fixed dimensionality of choice experiments ces previous simulation results show that d optimal design with correct a priori information generates more accurate valuation in the absence of a priori information random designs and designs incorporate attribute interactions result in more precise valuation estimates in this article monte carlo simulations demonstrate that the performances of different design strategies are affected by attribute information loads in ces consumer valuation estimates in simulation settings vary with the number of attributes

environmental quality competition and taxation in the presence of green network effect among consumers we examine the impact of a green network effect in a market characterized by consumers environmental awareness and competition between firms in terms of both environmental quality and product prices the unique aspect of this model comes from the assumption that an increase in the number of consumers of green brown product increases the satisfaction of each green brown consumer we show that paradoxically when the network effect of a green product is higher than that of a brown product this externality reduces product environmental quality and raises consumption of the green product conversely when the network effect of the brown product is higher the externality improves product environmental quality and raises consumption of the brown product in both cases the network effect does not affect the overall pollution level the externality correction requires the use of three optimal fiscal policies an ad valorem tax on products an emission tax and a subsidy or a tax on the green purchase a second best optimum can also be reached through the green taxation

game theoretic analysis of a bankruptcy problem from the talmud abstract for three different bankruptcy problems the 2000 year old babylonian talmud prescribes solutions that equal precisely the nucleoli of the corresponding coalitional games a rationale for these solutions that is independent of game theory is given in terms of the talmudic principle of equal division of the contested amount this rationale leads to a unique solution for all bankruptcy problems which always coincides with the nucleolus two other rationales for the same rule are suggested in terms of other talmudic principles needless to say the rule in question is not proportional division

look at me saving the planet the imitation of visible green behavior and its impact on the climate value action gap abstract examining the regional distribution of 15 different greenhouse gas mitigation practices mps across australia we study the tendency for consumers to imitate visible pro environmental behavior in their local region while there is a great deal of variation in the specific type of mps adopted by consumers located in the same region anova results suggest that they tend to adopt a similar number of mps as their neighbours using discrete choice modelling our results suggest that this is due to the peer adoption of certain visible mps such as using public transport or car pooling encouraging agents to adopt other types of visible mps however the character of this spillover is limited in that visible pro environmental behavior does not appear to influence the adoption of non visible mps we also find that social imitation patterns help individuals overcome the observed gap between their stated concern about climate change and their propensity to act on this concern known as the climate value action gap policy implications for designing effective green nudges are discussed

conflict leads to cooperation in demand bargaining abstract we consider a multilateral nash demand game in which short sighted players come to the bargaining table with requests for both coalition partners and the potentially generated resource we prove that the resulting process converges with probability one to a state in which all players agree on a strictly self enforcing division of resources i e a strict core allocation highlighting group dynamics we show how the myopic actions of players may lead to the break up of groups in the short run but can ultimately bring about a situation from which a strictly self enforcing allocation can be reached

assessing the impact of uncertainty on benchmarking the eco efficiency of dairy farming using fuzzy data envelopment analysis abstract the dairy sector is challenged to increase its eco efficiency which means minimizing environmental impacts while maintaining economic viability to quantify eco efficiency multiple environmental and economic indicators are needed data envelopment analysis dea has been used to evaluate the eco efficiency of agricultural systems accounting for multiple indicators simultaneously in practice however data used to calculate the economic and environmental performance of dairy farms can contain high levels of uncertainty standard dea is deterministic and does not consider data uncertainty fuzzy dea is a useful approach to account for uncertainties when benchmarking the eco efficiency of dairy farming in this study we therefore demonstrate how fuzzy dea can be used to evaluate the eco efficiency of dairy farming we used a case study of 55 dairy farms from different regions across western europe we used n surplus p surplus land use energy use as the environmental indicators and gross margin as the economic indicator we found that accounting for uncertainty around the value of environmental and economic indicators can affect substantially the eco efficiency of evaluated farms in addition fuzzy dea identified different set of peers compared to the peers of the standard dea all the aforementioned findings showed the importance of taking uncertainty into consideration in the benchmarking process and how fuzzy dea can be used to do so

how much trustworthy and salubrious an organic jam should be the impact of organic logo on the italian jam market abstract this paper studies the impact of organic logo in the italian jam market using data on true sales in italian supermarkets in the 2002 2004 period we estimate the structural demand model developed by berry 1994 this approach allows us to solve potential endogeneity problem in the estimation of the price coefficient in the demand equation as well as other aspects related to multiple sources of differentiation in a market where 62 percent of organic jams are diet this approach allows us to identify separately the market power induced by the organic logo and by the low content of sugar the estimation results from various specifications of gev class of models show that the organic attribute guarantees a degree of market power greater than the diet attribute however the protection from competition entailed by the organic logo is not particularly strong and the diet attribute does not guarantees additional protection to organic jams most importantly our findings show that consumers trust more big organic producers thus suggesting important policy implications on the supply and marketing side of the jam market

health and hunger nutrient response to income depending on caloric availability in nepal using data from nlss iii we estimate nutrient income elasticities for macronutrients vitamins and minerals we further allow for differential nutrient demand response to income depending on where a household is in the caloric availability distribution we find that some nutrients are income inelastic indicating that they are necessity goods while others are relatively income elastic we further test and reject equivalent nutrient income elasticities across the caloric availability distribution households in the lowest calorie quintile have highly income elastic nutrient demand leaving them vulnerable to income fluctuations moreover as households meet their first order caloric needs they substitute away from cheap calorie dense staples toward more expensive nutrient dense foods finally for most nutrients households in the highest calorie quintile exhibit more elastic nutrient demand similar to households in the lowest quintile our results suggest that policies aimed at improving income will likely also improve household nutrient availability particularly for the most calorie poor households they further suggest that policies aimed at protecting poor households from negative income shocks will also likely yield nutritional benefits

an assessment of the greek incentives scheme for photovoltaics abstract after two years of elaboration a new legislation was enacted in 2006 in greece providing an appealing feed in tariff fit scheme for photovoltaics pvs the response of the market was immediate with more than 7947 licenses having been submitted in less than 2 years time the effectiveness however of an incentives scheme cannot be judged solely by the response of prospective investors aim of this paper is to present and discuss a quantitative assessment of this newly introduced fit law in greece with respect to its attractiveness to investors its effectiveness towards launching a new market its cost efficiency and its ability to lift non economic barriers that led to significant delays in the diffusion of res over the last 10 years

green returns of labor income and human capital empirical evidence of the environmental behavior of households in developing countries abstract an important part of the environmental contamination comes from the daily practices of the households which has been partially ignored in the recent empirical literature the objective of this research is to examine the green returns of labor income and human capital in a developing country ecuador we use data from the national institute of statistics and census nisc during 2010 2016 and panel data econometrics techniques our results show that labor income and human capital plays a relevant role in the environmental behavior of households in this country both variables have a positive effect on the friendly environmental behavior of households in addition we found that the cantons 1 specialized in manufacturing have a poor environmental performance while the cantons specializing in services do not have a clear pattern we also don t find significant differences in the environmental behavior associated with the composition of the ethnic groups of each canton finally natural geographic regions generate differences in the environmental behavior of households one possible implication derived from this research is that those responsible for environmental policy can mitigate pollution by promoting educational programs with environmental content and encouraging improvements in the behavior of households using tax mechanisms

market and welfare effects of second generation consumer oriented gm products we examine the economic effects of the introduction of consumer oriented genetically modified gm products into the food system by developing a model of heterogeneous consumers and producers that allows for vertical and horizontal differentiation between the products available to consumers the model facilitates the estimation of consumer and producer surpluses in the product utility and product net returns spaces results show that the introduction of consumer oriented gm products can change the relationship between gm and conventional and organic products from one of vertical to one of horizontal product differentiation and can enhance both economic welfare and the market acceptance and growth of agricultural biotechnology

determinants of participation versus consumption in the nordic swan eco labeled market abstract this paper analyzes the determinants of demand for nordic swan eco labeled paper products and whether the factors determining the discrete decision to buy a swan labeled product are different from those that determine the quantity purchased using observed consumer purchase data from denmark we find that prices and socio demographic characteristics have a strong impact on the decision to purchase a swan labeled good the quantity consumed of swan labeled goods on the other hand is strongly affected by the availability of swan goods discounts and household size

do voluntary biotechnology labels matter to the consumer evidence from the fluid milk market this article examines the effects on the demand of voluntary labeling for the use of genetically modified growth hormone for retail fluid milk using supermarket scanner data retail fluid milk tracks one of the first biotechnology products approved is fairly standardized and ubiquitous and allows for cross sectional differentiation between labeled and unlabeled products and between conventional and organic brands the results indicate that voluntary labeling increases the demand for recombinant bovine growth hormone free milk in addition the estimated effects of labeling appear to have increased over time innovations through biotechnology enable agricultural producers to reduce production costs and or enhance product quality for many livestock and crop commodities at the same time however these innovations may affect the demand for the products that utilize those commodities many individuals for example are concerned about potential risks to human health although by no means all consumers have such concerns burton metcalfe and smith heiman just and zilberman the use of the recombinant bovine growth hormone rbgh in milk production has been a particular concern for some consumers as approximately one third of the united states dairy herd about 3 million dairy cows currently receive rbgh supplements monsanto product labeling particularly with respect to the provision of health and environmental information is increasingly being used to provide information about product characteristics such as biotechnology content that

offset carbon emissions or pay a price premium for avoiding them a cross country analysis of motives for climate protection activities abstractthis article contributes to the economic literature on pure and impure public goods by considering two alternatives for contributing to the public good climate protection offsetting carbon emissions from conventional consumption or paying higher prices for climate friendly products we empirically examine a wide range of motives and their impact on individuals choice in favour of these two alternatives relying on data from representative international surveys our results indicate that environmental awareness warm glow motives and the desire to set a good example have the most robust effects on both climate protection activities in germany and the united states however some motives differ considerably between both alternatives and the two countries a green identity enhances the willingness to pay a price premium for climate friendly goods or services in germany while social norms seem to be of much higher relevance in the united states our results further suggest that the choice of climate

differences between continuous and discrete contingent value estimates in a split sample contingent valuation study of willingness to pay wtp for food safety improvements the dichotomous choice dc elicitation method consistently generated much larger estimates of wtp than did a continuous method little or none of these differences was due to bias introduced by the statistical techniques used with the dc data most or all of the difference was due to differences in respondent behavior in addition the continuous wtp responses showed a significant scope effect while the dc responses did not the observed difference in behavior may be attributable in part to yea saying by dc respondents

explaining the choice of organic produce cosmetic defects prices and consumer preferences the choice between organic and conventional produce was estimated empirically using a two equation probit model data were collected in store on cosmetic defects produce prices and consumers demographic and economic traits store choice displayed a significant impact on the probability of purchasing organic produce shoppers at the specialty grocer were sensitive to price differences between organic and conventional items households with children under eighteen were more likely to purchase organic produce while shoppers with graduate or professional degrees were less likely to do so differences in cosmetic defects had statistically significant albeit small effects on the probability of purchasing organics

a model of financial crises in emerging markets recent events in mexico asia russia and brazil have underscored that a satisfactory explanation of financial crises in emerging markets remains elusive not too long ago the prevailing view was that crises were the inevitable outcome of ongoing fiscal imbalances coupled with fixed exchange rates but this first generation view pioneered by krugman 1979 has fallen out of fashion because in many crises the crucial fiscal disequilibria were absent and as obstfeld 1994 has argued currency crises have sometimes occurred even though central banks had more than enough resources to prevent them witness much of europe in the early 1990s obstfeld put forward a second generation view in which central banks may decide to abandon an exchange rate peg when the unemployment costs of defending it become too large this new perspective implied that crises could be driven by self fulfilling expectations since the costs of defending the peg may themselves depend on anticipations that the peg will be maintained but obstfeld s emphasis on mounting unemployment and domestic recession while appropriate for the erm 1992 crisis was at odds with the facts in mexico in 1994 and east asia in 1997 asian

is there a hold up problem most literature on the hold up problem starts from the assumption that ex post bargaining outcomes are insensitive to prior investment costs we argue that this approach is unsatisfactory if the bargaining procedure is relatively symmetric it typically admits multiple perfect equilibria some of which give the investor a high enough payofi to sustain e cient investment even if the bargaining procedure is asymmetric and rigged against the investor there may be investment if agents are driven by moral concerns or if communication creates commitment laboratory experiments indicate that communication is necessary and su cient for agents to coordinate on e cient outcomes when the bargaining game is symmetric when the bargaining game is rigged against the investor the hold up problem is mitigated but not eliminated by moral behavior communication is quite credible and we flnd that promises are more believable than threats

conventional contracts intentional behavior and logit choice equality without symmetry abstract when coordination games are played under the logit choice rule and there is intentional bias in agents non best response behavior we show that the egalitarian bargaining solution emerges as the long run social norm without intentional bias a new solution the logit bargaining solution emerges as the long run norm these results contrast with results under non payoff dependent deviations from best response behavior where it has previously been shown that the kalai smorodinsky and nash bargaining solutions emerge as long run norms we complement the theory with experiments on human subjects results of which suggest that non best response play is payoff dependent and displays intentional bias this suggests the egalitarian solution as the most likely candidate for a long run bargaining norm

from rational actor to efficient complexity manager exorcising the ghost of homo economicus with a unified synthesis of cognition research it is now commonplace to note that economics canonical model of humans as rational self interested utility maximizers homo economicus is both descriptively misleading and often insufficiently predictive however certain outdated assumptions tied to homo economicus persist often influencing discourse and research design even in sustainability oriented fields we argue this ghost of homo economicus endures because the diversity of findings that confound the canonical model has surfaced across multiple behavioral and cognitive sciences each with its own terminology and focus area as such a unified accessible synthesis of this new information has yet to emerge in this paper we review recent insights from across the behavioral and cognitive sciences and propose an efficient complexity manager ecm model homo efficens as the best synthesizing option the crux of this model is that our species works within biological limits to efficiently filter massive environmental complexity this is achieved largely through analogical or case based reasoning we explain this synthesized model using a series of accessible metaphors finally we speculate on how this model may enrich future sustainable development research insofar as it points to fruitful units of analysis can stimulate methodological innovation and provide a more explicit theoretical foundation for the field

success factors for environmentally sustainable product innovation a systematic literature review the growing awareness regarding environmental sustainability has fully reached business reality consumers and companies alike are looking for alternatives to mitigate pressing environmental demands resulting from continuous population and economic growth on the other hand companies must deal with an increasingly competitive scenario where innovation is regarded as a survival need in most markets it is thus clear that systematic academic research is paramount to guide companies to succeed in environmentally sustainable product innovation in this context this paper i consolidate extant research and aggregate findings of different studies on environmentally sustainable product innovation through an interpretative framework of published literature on the topic and ii map critical success factors that drive the success of product innovation developed in this new logic of production and consumption to achieve these objectives a systematic literature review on environmentally sustainable product innovation was conducted results show that there are four main critical success factors for environmentally sustainable product innovation market law and regulation knowledge interfunctional collaboration innovation oriented learning and r d investments the factors identified in this research and corresponding variables were subjected to a brief empirical test by professionals the test allowed a preliminary approval of the developed framework and identification of the most important variables within each factor a research agenda based on the state of the art on the topic is also proposed

clever agents in young s evolutionary bargaining model in the models of young 1993 econometrica61 57 84 1993 j econ theory59 145 168 boundedly rational individuals are recurrently matched to play a game and they play myopic best replies to the recent history of play it could therefore be an advantage to instead play a myopic best reply to the myopic best reply something boundedly rational players might conceivably also do we investigate this possibility in the context of young s j econ theory59 145 168 bargaining model it turns out that cleverness in this respect indeed does have an advantage in some cases however if all individuals are equally informed about past play in a statistical sense then the nash bargaining solution remains the unique long run outcome when the mutation rate goes to zero journal of economic literature classification numbers c70 c78

currency crises and monetary policy in an economy with credit constraints this paper presents a simple model of currency crises which is driven by the interplay between the credit constraints of private domestic firms and the existence of nominal price rigidities the possibility of multiple equilibria including a currency crisis equilibrium with low output and a depreciated domestic currency results from the following mechanism if nominal prices are sticky a currency depreciation leads to an increase in the foreign currency debt repayment obligations of firms and thus to a fall in their profits this reduces firms borrowing capacity and therefore investment and output in a credit constrained economy which in turn reduces the demand for the domestic currency and leads to a depreciation we examine the impact of various shocks including productivity fiscal or expectational shocks we then analyze the optimal monetary policy to prevent or solve currency crises we also argue that currency crises can occur both under fixed and flexible exchange rate regimes as the primary source of crises is the deteriorating balance sheet of private firms

adaptive play in multiplayer bargaining situations we study the dual issues of allocation and coalition formation in a model of social learning for a class of economies which can be expressed in terms of a real valued characteristic function we first show that all self perpetuating allocations realized from a simple bargaining game must be core allocations although players make simultaneous demands for surplus and only on their own behalf following this we provide a sufficient condition under which the society eventually learns to divide the surplus according to some core allocation regardless of the initial history

do native and invasive labels affect consumer willingness to pay for plants evidence from experimental auctions ornamental plant sales have been identified as an important vector for the introduction of invasive plants increased concerns about the economic and ecological costs of invasive plants have spawned interest in identifying strategies to curtail introductions one possible strategy is labeling plants based on whether they are invasive or native the primary purpose of this paper was to explore how labeling plants based on invasive and native attributes might affect consumer demand to accomplish this objective a second price auction was used to elicit the willingness to pay wtp for plants with and without labels on average we found a 0 35 premium for plants labeled as noninvasive and native and a 1 01 to 1 66 discount for plants labeled as invasive the size of these premiums and discounts differed in relation to various demographic attitudinal and preference related factors overall our results suggest that labeling plants as invasive or native could be a viable strategy for reducing the introduction of invasive plants

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

on the gap between payment card and closed ended cvm answers the paper presents contingent valuation cv estimates of benefits provided by a proposed kalkalpen national park in austria although descriptive results of welfare measures are presented the focus of the paper is on methodological questions concerning the analysis of cv answers evidence is given regarding the difference between payment card pc answers and closed ended question formats based on different estimation models for cv questions substantial differences are found between closed ended and payment card welfare measures on average pc willingness to pay wtp measures are below the closed ended figures since the evaluation models are based on different premises in the calculation of wtp figures a more precise disclosure of the underlying evaluation methods is required if different question formats are compared to one another identical assumptions on the probability distributions have to be assumed whenever open and closed ended cv welfare measures are compared taking theoretical argument

economics and identity this paper considers how identity a person s sense of self affects economic outcomes we incorporate the psychology and sociology of identity into an economic model of behavior in the utility function we propose identity is associated with different social categories and how people in these categories should behave we then construct a simple game theoretic model showing how identity can affect individual interactions the paper adapts these models to gender discrimination in the workplace the economics of poverty and social exclusion and the household division of labor in each case the inclusion of identity substantively changes conclusions of previous economic analysis

the effect of decision weights in bargaining problems abstract bargaining problems are considered where the preferences of the bargainers deviate from expected utility but can be modelled according to rank dependent utility theory under rank dependent utility both the utility function and the probability weighting function influence the risk attitude of a decision maker the same definition of risk aversion leads to two forms of risk aversion utility risk aversion and probabilistic risk aversion the main finding is that these two forms can have surprisingly opposite consequences for bargaining solutions that exhibit a weak monotonicity property in particular in a large class of bargaining problems both increased utility risk aversion and decreased probabilistic risk aversion of the opponent are advantagous for a player this is demonstrated for the kalai smorodinsky bargaining solution the nash bargaining solution does not behave regularly in this respect

putting their money where their mouths are consumer willingness to pay for multi ingredient processed organic food products in response to dramatically increasing adoption in consumer markets the national organic program nop initiated novel labeling standards for food products in the us in 2002 this program is a particularly relevant standardization effort for multi ingredient processed foods rather than a simple binary message organic or not gradations of organic content are now codified no existing published study evaluates consumer willingness to pay or motivation to purchase in response to such a rich organic label this article presents evidence of the impact of the nop through analysis of data collected in seven central ohio usa grocery stores results suggest that consumers are willing to pay premium prices for organic foods even those with less than 100 organic ingredients the magnitudes of wtp premia varied significantly among consumer groups suggesting that targeted marketing may be effective for organic merchandisers

pesticide risk valuation in empirical economics a comparative approach abstract pesticide use in agriculture poses several risks to both human health and nontarget agro ecosystems due to lack of information on the monetary value of reducing pesticide risks it is difficult to perform an economic analysis that addresses social efficiency of policy and draws conclusions about the appropriate degree of regulation the aim of the current paper is to present a critical overview of the empirical literature on pesticide risk valuation that provides disaggregate willingness to pay estimates wtps of pesticide risks reduction recent multidimensional classification methods such as coined decision tree analysis are used in a comparative approach as tools for explaining the differences in empirical research findings the analysis shows that the order of magnitude of wtps is related to both the valuation technique and to the data available from biomedical and ecotoxicological literature it also shows that wtp estimates of pesticide risks cannot be simply averaged over several empirical studies the order of magnitude of a wtp estimate is in fact related to the specific type of risk and to the nature of the risk scenario considered as well to lay people s subjective perception of risks

the character of demand in mature organic food markets great britain and denmark compared abstract we investigate the organic food market in two selected european countries great britain and denmark identifying main differences and similarities we focus particularly on consumer perceptions and priorities labelling schemes and sales channels as a basis for assessing market stability and prospects for future growth we employ a unique set of household panel data that includes information on stated values and concerns as well as registered purchasing behaviour most organic food on both markets is produced and processed by large scale industrialised units and distributed through mainstream sales channels consumer confidence being sustained at present by organic labelling schemes that appear to function well however a parallel market based on the supply of goods through various direct sales channels to heavy users prevails we find that organic food purchase decisions are primarily motivated by private good attributes such as freshness taste and health benefits attributes that may be perceived as being compatible with modern production and sales structure mature markets for organic foods nevertheless appear to be vulnerable to consumer dissatisfaction particularly among heavy users of organic food products

use of economic instruments in the german renewable electricity policy this article surveys the economic instruments adopted in germany since the start of the previous decade and analyse the factors determining their effectiveness it is found out that their effect has always diminished in correspondence of increased uncertainty on the future of the system in particular while in two of these instances uncertainty was mainly due to national factors in the other the debate on the european renewable directive played a very important role recent changes in the production incentives have introduced a process simulating the effect of competition among renewable generators it is pointed out that the biennial revision of the rates can increase the uncertainty intrinsic in the policy on the other hand this process also provides a forum for the debate on the future of the renewable sector one can notice that currently germany the biggest renewable market in europe is granting one of the lowest production incentives this is rather curious as germany never relied on market competition in order to increase the renewable electricity production

recontracting and stochastic stability in cooperative games abstract an evolutionary style model of recontracting is given which guarantees convergence to core allocations of an underlying cooperative game unlike its predecessors in the evolution learning literature this is achieved without assumptions of convexity of the characteristic function or a reliance on random errors the stochastic stability properties of the model are then examined and it is shown that stochastically stable states solve a simple and intuitive minimization problem which reduces to maximizing a rawlsian swf for a common class of utility functions in contrast to previous analyses the stochastically stable state is unique for a broad class of utility functions

willingness to pay for natural organic and conventional foods the effects of information and meaningful labels vague food labels and distorted product claims have persisted in the natural food industry while organic claims can be certified by the u s department of agriculture usda using experimental methods and a sample of randomly selected subjects we test food label and information treatment effects on subjects willingness to pay wtp for organic natural and conventional foods random nth price auctions are used to elicit wtp after subjects received one of five randomly assigned information treatments we find large information effects including asymmetric cross market effects for natural and organic foods perhaps surprising is that organic premiums increase in response to subjects seeing the natural foods industry s perspective on its products demographics effects are also important the results have practical implications for natural and organic food marketing and valuing products where there are vague claims about their attributes

willingness to pay for the green food in china abstract with use of payment card survey data of willingness to pay wtp for the green food a unique food certification in china this study finds that age and income are important for the wtp for the green food in china there are structural differences in consumer preference for green food between the large city and the small county consumers in china on average are willing to pay 47 more for green vegetables and 40 more for green meat than for their conventional counterparts compared with the real markets and the previous studies our results are very consistent and reliable

eco efficiency as a sustainability measure for kiwifruit production in new zealand abstract assessing the sustainability of orchards focuses on quantifying environmental impacts and resource consumption sustainable orchards also have to be profitable and socially responsible we aimed to identify sustainable kiwifruit production in the bay of plenty new zealand by considering orchards environmental and economic performance we conducted a survey of 40 orchards with different cultivars actinidia deliciosa hayward green v actinidia chinensis hort16a gold and management integrated v biogro certified organic assessment of environmental performance was restricted to greenhouse gas emissions carbon footprint of the orchard phase we defined eco efficiency on an area basis as nzd net profit per kg greenhouse gas emissions 1 nzd 0 83 usd 31 10 2013 carbon footprints for the cultivars and management systems were comparable the choice of functional unit namely land area and 1 kg of produce did not affect the result our analysis revealed fertilizer use and the n associated emissions as hot spots for greenhouse gas emissions opportunities to reduce greenhouse gas emissions arise in the background system of fertilizer production packaging storage and transport and the optimization of nutrient use efficiency in the orchard the integrated system had insignificantly higher greenhouse gas emissions than the organic system taking into account the profitability of the orchards the eco efficiency of organic orchards was significantly higher than that of integrated orchards we demonstrated that the metric of eco efficiency can enhance product differentiation for customers and can also assist orchardists to find the most sustainable management system however the volatility of commodity markets and changing consumer preferences remain challenges

quality quantity and spatial variation of price this paper develops and implements a method for estimating price elasticities of demand using cross sectional household survey data geographically clustered households report unit values which when corrected for quality effects and for measurement error indicate the underlying spatial variation in prices and can be matched to variation in demand patterns a simple model of quality choice is proposed while the correction for measurement error exploits the clustered design of such surveys data from a 1979 household survey from the ivory coast are used to estimate price elasticities for beef meat fish cereals and starches copyright 1988 by american economic association

evolutionary bargaining with intentional idiosyncratic play abstract we study equilibrium selection in stochastic evolutionary bargaining games in which idiosyncratic play is intentional instead of random in contract games the stochastically stable state selected by intentional idiosyncratic play is the nash bargain rather than the usual kalai smorodinsky solution

the demand for organic foods in the south of italy a discrete choice model abstract this paper analyses organic food consumer s demand that can help advising on implementing organic food policies at european level or for a particular european country in particular it investigates the main factors explaining organic food demand in the south of italy following the lancaster consumer s demand theory we assume that consumer s utility depends on product characteristics instead of the product itself thus consumers will choose the product organic versus conventional that possesses the combination of attributes that maximises its utility consumer s choice for organic foods is analysed within the random utility discrete choice model and a bivariate probit model has been specified the data were collected through a questionnaire conducted in the italian region of campania naples in 2003 findings indicate that economic factors are still factors limiting the growth of organic demand in europe moreover the consumers perceived benefits of organic food environmental and health are factors promoting organic food demand in addition greater information on organic food products is crucial to expand its demand in the south of italy because this information will increase the consumer s organic knowledge then higher organic knowledge will increase the probability to buy organic foods and to a larger extent the level of consumption among existing consumers

evaluation of property tax bonus to promote solar thermal systems in andalusia spain abstract this paper evaluates the effects of a property tax bonus to promote the installation of solar thermal energy systems in buildings in andalusia southern spain the propensity score matching methodology is used the treatment group consists of municipalities of andalusia that established property tax bonuses in their municipalities in 2010 the control group consists of municipalities that did not the response variable measures the number of new square meters of solar thermal systems installed in 2010 the analysis leads to the conclusion that municipalities that established a property tax bonus had installed on average 102 245 to 122 389 square meters more these results indicate that the percentage increase in squares meters installed in municipalities which adopted the tax bonus promotion ranged from 70 74 to 98 38 these percentages were lower for rural municipalities 49 00 to 77 06

bubbles and capital flow volatility causes and risk management emerging market economies are fertile ground for the development of real estate and other financial bubbles despite these economies significant growth potential their corporate and government sectors do not generate the financial instruments to provide residents with adequate stores of value capital often flows out of these economies seeking these stores of value in the developed world bubbles are beneficial because they provide domestic stores of value and thereby reduce capital outflows while increasing investment but they come at a cost as they expose the country to bubble crashes and capital flow reversals we show that domestic financial underdevelopment not only facilitates the emergence of bubbles but also leads agents to undervalue the aggregate risk embodied in financial bubbles in this context even rational bubbles can be welfare reducing we study a set of aggregate risk management policies to alleviate the bubble risk we show that prudential banking regulation sterilization of capital inflows and structural policies aimed at developing public debt markets and property rights all have a high payoff in this environment

when households go solar determinants of uptake of a photovoltaic scheme and policy insights abstract the need to reduce dependence on fossil fuels has resulted in escalating interest in renewable energy generation yet few countries have seriously tested household potential to produce energy from pv panels propelled by mandatory eu targets for renewable energy and constrained with limited territory the government of malta launched a subsidy scheme with a view to encouraging pv installation by households the scheme reached the desired adoption levels within a very short period of time the study takes an entire country dimension to assess the determinants of household investment in pv panels a unique dataset is specifically constructed for this study we find that the prevalence of younger households higher incomes dwelling ownership and unshared roof space results in higher rates of uptake neither higher educational levels nor the participation in other environmental schemes recycling contribute any explanatory power to uptake of pv panels pro government sentiment captured by voting outcomes significantly and positively influences the take up of the grant and installation of pv panels we conclude by identifying some pointers for policy makers interested in harvesting the potential of households

non cooperative bargaining theory an introduction the paper provides an informal introduction to some of the main themes of the recent literature on non cooperative or sequential bargaining models it focuses in particular on the relationship between the new approach and the traditional axiomatic approach exemplified by nash bargaining theory it illustrates the new insights offered by the non cooperative approach by reference to a detailed analysis of the manner in which the presence of an outside option available to one of the parties will affect the negotiated outcome finally the difficulties which arise in extending this analysis to two person bargaining with incomplete information and to n person bargaining are discussed this is a revised version of the fourth review of economic studies lecture presented in april 1985 at the joint meeting of the association of university teachers of economics and the royal economic society held in oxford the choice of lecturer is made by a panel whose members are currently professors hahn mirrlees and nobay and the paper is refereed in the usual way this paper aims to provide an informal and elementary introduction to an approach to bargaining which has received a great deal of attention over the past few years the approach involves writing down some particular sequence of moves offers and replies to be made over time in the course of negotiations and then looking for a non cooperative equilibrium in the game thus specified in practice a perfect equilibrium or in games of incomplete information a sequential equilibrium while the approach appears at first sight to be very different in spirit from the traditional axiomatic approach in which a bargaining solution is specified by appealing to a number of general requirements which are deemed appropriate on the basis of some a priori considerations the two approaches are in fact complementary while the

political consumerism and public policy good complements against market failures political consumerism has become over the past years an ever growing phenomenon by which citizens express through their consumption their political environmental and ethical opinions this paper discusses political consumerism from an economic science perspective focusing on the link between political consumerism and public policies it wonders to what extent political consumerism may represent an effective and fair instrument against market failures overall it seems that it would be better to consider it as a complement to conventional public policies

economists models of learning abstract economic theorists have intensively studied learning in games and decisions over the last decade this essay puts some of the work in perspective and offers opinions about what still needs to be learned journal of economic literature classification numbers c73 d83

does organic command a premium when the food is already local the emergence of community supported agriculture csa farms has been recognized as a new way for small farms to remain competitive while engaging in their local community through direct marketing in this study we report on first revealed preference valuation of csa attributes using data on share prices and csa characteristics for the summer 2012 growing season using data covering 453 csa farms in michigan new york ohio and pennsylvania we develop a hedonic model based on firm level prices to reveal consumer valuations of csa attributes including various types of organic certification we also test for competition in the csa market using a model of firm entry to evaluate whether firms appear perfectly competitive which is a requirement when using firm level prices in our hedonic analysis our results reveal a price premium of approximately 7 for usda organic certification although this value is heterogeneous across states we find no premium associated with competing certified naturally grown programs finally we find that csa farms exhibit little market power and appear to act competitively even with few market entrants

self confirming equilibrium rium path of play thus if a self confirming equilibrium occurs repeatedly no player ever observes play that contradicts his beliefs even though beliefs about play at off path information sets need not be correct we characterize the ways in which self confirming equilibria and nash equilibria can differ and provide conditions under which self con firming equilibria correspond to standard solution concepts nash equilibrium and its refinements describe a situation in which i each player s strategy is a best response to his beliefs about the play of his opponents and ii each player s beliefs about the opponents play are exactly correct we propose a new equilibrium concept self confirming equilibrium that weakens condition ii by requiring only that players beliefs are correct along the equilibrium path of play thus each player may have incorrect beliefs about how his opponents would play in contingencies that do not arise when play follows the equilibrium and moreover the beliefs of different players may be wrong in different ways the concept of self confirming equilibrium is motivated by the idea that noncooperative equilibria should be interpreted as the outcome of a learning process in which players revise their beliefs using their observations of previous play suppose that each time the game is played the players observe the actions chosen by their opponents but that players do not observe the actions their opponents would have played at the information sets that were not reached along the path of play then if a self confirming equilibrium occurs repeatedly no player ever observes play that contradicts his beliefs so the equilibrium is self confirming in the weak sense of not being inconsistent with the evidence by analogy with the literature on the bandit problem e g rothschild 1974 one might expect that a non nash self confirming equilibrium can be the outcome of plausible learning processes this point was made by fudenberg and

exploring the gap between consumers green rhetoric and purchasing behaviour why do consumers who profess to be concerned about the environment choose not to buy greener products more regularly or even at all this study explores how consumers perceptions towards green products consumers and consumption practices termed green perceptions contribute to our understanding of the discrepancy between green attitudes and behaviour this study identified several barriers to ethical consumption behaviour within a green consumption context three key themes emerged from the study it is too hard to be green green stigma and green reservations there is currently a perception based on a number of factors that it is too hard to be green which creates a barrier to purchasing green products furthermore some consumers were reluctant or resistant to participate in green consumption practices due to their unfavourable perceptions of green consumers and green messages this article suggests that green perceptions may influence consumers intention to purchase green products accordingly it discusses the implications and suggests avenues for future research

cultural integration and its discontents a community s culture is defined by the preferences and equilibrium behaviours of its members contacts among communities alter individual cultures through two interrelated mechanisms behavioural adaptations driven by pay offs to coordination and preference changes shaped by socialization and self persuasion this paper explores the workings of these mechanisms through a model of cultural integration in which preferences and behaviours vary continuously it identifies a broad set of conditions under which cross cultural contacts promote cultural hybridization the analysis suggests that policies to support social integration serve to homogenize preferences across communities thereby undermining a key objective of multiculturalism yielding fresh insights into strategies pursued to influence cultural trends it also shows that communities benefit from having other communities adjust their behaviours

constrained egalitarian allocations abstract this paper proposes a constrained egalitarian solution concept for tu games which combines commitment for egalitarianism and promotion of individual interests in a consistent manner the paper shows that the set of constrained egalitarian allocations is nonempty for weakly super additive games the solution is almost unique if the desirability relation between players is complete

driving factors for the success of the green innovation market a relationship system proposal this study aims to map out the relationships that make up green innovation initiatives in brazilian industry the sample comprised 100 managers at manufacturing companies most of them operating in the business of farm machinery and equipment 45 managers and steel structures 14 managers to develop this study medeiros et al j clean prod 65 76 86 2014 study mapping critical factors that drive the success of green product innovation and the paradigm of complexity was used as a reference study based on the results it was possible to identify that the operational dynamic of the factors and variables that affect market success do not happen in an isolated or fragmented way they occur systematically with different contingencies and structured basic and intermediate skills in order to meet the expectations of consumers laws and environmental legislation initially the technological expertise factor was noted as very important for sustaining green product innovation furthermore since proactive leaders are an important factor for successfully developing environmentally sustainable products it must be added to technological expertise as the foundation for developing green innovation after defining the basis for green product innovation the intermediary conditions necessary for using the available technology appropriately were mapped out in this sense variables such as elimination of cultural barriers capacity for critical reflective analysis and experimentation are also very important in addition some of the variables of the cross functional collaboration and market knowledge factors were a part of the structure that organizations need to transform potential into developing green products which is the basis for the third level of the model the fourth level of the model has the meeting consumer expectations and following law and legislation factors which make up the main goals for developing environmentally sustainable products according to a number of surveys that were conducted

stochastic stability in a double auction abstract in a k double auction a buyer and a seller must simultaneously announce a bid and an ask price respectively exchange of the indivisible good takes place if and only if the bid is at least as high as the ask the trading price being the bid price with probability k and the ask price with probability 1 k we show that the stable equilibria of a complete information k double approximate an asymmetric nash bargaining solution with the seller s bargaining power decreasing in k note that ceteris paribus the payoffs of the seller of the one shot game increase in k nevertheless as the stochastically stable equilibrium price decreases in k choosing the seller s favorite price with a relatively higher probability in individual encounters makes him worse off in the long run

house price booms current account deficits and low interest rates one of the most striking features of the period before the great recession is the strong positive correlation between house price appreciation and current account defi cits not only in the united states but also in other countries that have subsequently experienced the highest degree of fi nancial turmoil a progressive relaxation of credit standards can rationalize this empirical observation lower collateral requirements facilitate access to external funding and drive up house prices the current account turns negative because households borrow from the rest of the world at the same time however the world real interest rate counterfactually increases the two key ingredients that reconcile a demand based explanation of house price booms and current account defi cits with the evidence on real interest rates are nominal interest rates lower than the predictions of a standard monetary policy rule in leveraged economies and foreign exchange rate pegs in saving countries

alternative models of individual behaviour and implications for environmental policy abstract most insights of environmental economics are in line with the standard neoclassical economic model of rational behaviour formulated in terms of maximization of utility in general or of profits in particular the standard theory of environmental policy is a case in point however the maximization hypothesis and its methodological foundation have been criticized on many grounds related to a lack of either logical or empirical content moreover over the years a great many alternative models of behaviour have been proposed both criticism and alternatives are surveyed here attention is devoted to relevant insights from the philosophy of science the notion of methodological individualism and other criticism the alternative behavioural models include bounded rationality and satisficing lexicographic preferences habitual behaviour incommensurability and multicriteria evaluation and various models of behaviour under uncertainty major implications of the criticism and alternative models of individual behaviour for environmental policy theory are outlined

yes in my backyard spatial differences in the valuation of forest services and local co benefits for carbon markets in mexico forests provide many and large benefits including cost efficient climate change mitigation however international carbon markets have not stimulated the demand for forestry offsets domestic market mechanisms are emerging in many countries and forests could be highly valued through these policies as most of the benefits produced by forests are enjoyed locally here a choice experiment explores drivers of valuation and willingness to pay for forest carbon services in voluntary markets in mexico by comparing the valuation of citizens from four regions to test geographical preference for projects n 645 findings from multinomial logit models show valuation of forest carbon services is transferable and citizens would pay more for offsets from projects closer to their homes proximate forests provide a range of co benefits to local users including environmental services and opportunities for recreation factors related to valuation include sense of responsibility previous knowledge of carbon emissions previous visits to the sites regional identification and the valuation of local environmental services e g improvements in local air quality knowledge of spatial heterogeneity in valuation of the use of forest services can help to design market based instruments by identifying highly valued areas for environmental services programs and carbon markets

sovereign debt crisis in a monetary union accounting for excessive debt housing bubbles and the transmission of crises despite vast empirical documentation of the recent sovereign debt crisis in southern europe there is little research accounting for the following stylized facts in a single coherent framework continuous borrowing high growth housing bubbles and current account deficits since the beginning of the european monetary union ending with a sudden crisis and subsequent contagion of crisis we fill this gap by proposing a model and fitting it to the data using a growth model with collateral constraints of small peripheral economies in the institution of a monetary union we analyze the multilayer moral hazards underlying excessive borrowing since housing bubbles can support a constant loan to value ltv ratio lower than ltv limits peripheral economies can lock into a steady state ponzi growth equilibrium with high growth and current account deficits but these economies become vulnerable to crises we identify the self fulfilling crisis region sfcr in which the economy grows fast with a seemingly safe ltv ratio but with a vulnerability to crises moreover a crisis in one sector propagates to other sectors by endogenously expanding their sfcrs we derive some policy implications on ltv regulations and market psychology finally our calibration exercise presents how bubbles develop and burst along with contagion across sectors accounting for the data jel e44 f34 o16

using semiparametric models to study nutrition improvement and dietary change with different indices the case of china in company with rapid economic growth chinese consumers have seen a remarkable nutrition improvement and a dramatic dietary change this article investigates the driving forces behind these changes with use of the china health and nutrition survey chns data this paper first proposes 10 different indices to measure nutrition improvement and dietary change from different perspectives and then adopts semiparametric panel data models to capture the complicated nonlinear relationship between these nutrition indices and income growth while controlling for other variables parametrically this enables us to directly predict the nutrition improvement and dietary change at different income levels from different aspects this paper particularly finds that nutrition improvement and dietary change will continue in china but will slow down in the future with further income growth

an evolutionary model of bargaining abstract individuals from two populations of bargainers are randomly matched to play the nash demand game they make their demands by choosing best replies based on an incomplete knowledge of the precedents and occasionally they choose randomly there is no common knowledge over the long run typically one division will be observed almost all of the time this stochastically stable division is close to the nash solution when all agents in the same population are alike when the populations are heterogeneous a generalization of the nash solution results if there is some mixing between the two populations the stable division is fifty fifty journal of economic literature classification number c78

does education increase pro environmental behavior evidence from europe abstract it is often observed that individuals with higher education levels tend to be more environmentally friendly yet the causal evidence is lacking because there may well be omitted variables that cause individuals to attain more education and also cause individuals to be environmentally conscious we implement a regression discontinuity design to estimate the increase in educational attainment due to changes in compulsory education laws in 20th century europe this allows us to overcome the identification problem of endogenous educational attainment using two waves of eurobarometer surveys we find a positive local average treatment effect for 7 of the 8 pro environmental behaviors an analysis of related questions on the survey supports the notion that education causes individuals to be more concerned with social welfare and to accordingly behave in a more environmentally friendly manner

stochastic stability under logit choice in coalitional bargaining problems abstract this study examines a dynamic process of n person coalitional bargaining problems we investigate the evolution of social conventions by embedding a coalitional bargaining setting in a dynamic process in each period a group of players may make some coalitional move that is forming a new team or negotiating the division of a surplus players revise their coalitions and surplus divisions over time in the presence of stochastic noise which leads players to make a suboptimal decision under a logit specification of choice probabilities we find that the stability of a core allocation decreases in the wealth of the richest player furthermore stochastically stable allocations are core allocations that minimize the wealth of the richest player

does evolution solve the hold up problem abstract the paper examines the theoretical foundations of the hold up problem at the first stage one agent decides on the level of a relationship specific investment there is no contract so at the second stage the agent must bargain with a trading partner over the surplus that the investment has generated we show that the conventional underinvestment result hinges crucially both on the assumed bargaining game and on the choice of equilibrium concept in particular we prove the following two results i if bargaining proceeds according to the nash demand game any investment level is subgame perfect but only a particular efficient outcome is stochastically stable ii if bargaining proceeds according to the ultimatum game with the trading partner as proposer only the minimal investment level is subgame perfect but any investment level is stochastically stable journal of economic literature classification numbers l14 c78

economic growth with bubbles this paper presents a stylized model of economic growth with bubbles this model views asset price bubbles as a market generated device to moderate the effects of frictions in financial markets improving the allocation of investments and raising the capital stock and welfare the model illustrates various channels through which asset price bubbles affect the incentives for innovation and economic reforms and therefore the rate of economic growth the model also offers a new perspective on the effects of financial development on asset price bubbles and economic growth

the demand for food quality in rural china many studies of food demand do not use actual prices but unit values obtained by dividing expenditures by the quantity consumed this can bias empirical analyses because unit values are not exogenous market prices they reflect household food quality choices within each food category this article develops a framework for assessing the resulting bias in income and price elasticities of demand and applies the framework to data for rural china empirical results indicate that households in rural china tend to consume higher quality food as income increases with a greater sensitivity to income for basic foods than for luxury foods copyright 2009 oxford university press

technological diffusion and preference learning in the world of homo sustinens the challenges for politics abstract this article relates agents learning of a preference for a technology competition of technologies and their relative diffusion among potential adopters competitive interactions between two technologies are captured by an extended lotka volterra model to also incorporate preference learning on the part of potential adopters of these technologies we combine it with a model of cultural learning based on role model conformist and hedonistic learning our theoretical analysis is illustrated by a concrete example the competition between electric mobility and conventional forms of individual mobility the model enables an evaluation of specific policy instruments as to the promotion of sustainable technology

towards sustainable consumption economic modelling of mobility and heating for austria abstract the paper focuses on economic modelling and empirical analysis of sustainable structures in private consumption and strives to extend conventional economic consumption models the model analysis of sustainable consumption in the areas heating and transport for austria attempts to depart from traditional measurement of consumption in national accounts and economic consumption models the focus of the analysis is laid on consumer services derived from a combination of stocks e g building stock transport systems and flows mainly energy this approach intends to illustrate that a concentration on flows in consumption models lacks important aspects of sustainable consumption the economic analysis of sustainable consumption patterns aims to highlight the effects related to the substitution of flows by stocks in the consumption areas transport and heating e g improvements in thermal quality of buildings more energy efficient transport systems relevant too in this respect is the role that can be played by technological innovation improvements in energy efficiency of stocks the potential for specific incentives to promote new technologies two essential factors are crucial in the context of sustainable consumption the demand shifts concerning the consumer services desired and the composition of the stock flow mix necessary for the service provision

habit spillovers or induced awareness willingness to pay for eco labels of rice in china abstract the willingness to pay wtp for eco labeled rice is investigated for chinese consumers using choice experiments with information interventions the mixed logit model shows preference heterogeneities and the latent class model unveils two sources pro environmental behaviors with spillover effects which are defined as catalyst behaviors and the awareness about imperatives of ecological farming which is defined as induced awareness classification results identify that using bp bags and sorting waste are catalyst behaviors as the multivariate ordered probit model implies consumers with higher educational attainment and family income levels are more likely to adopt these behaviors instead of creating the preference for eco labels the induced awareness is only found to strengthen preferences that already exist the results of this study provide policy implications for the design of proper strategies to develop the eco labeled food market especially in developing economies

the impact of climate information on milk demand evidence from a field experiment it has been suggested that carbon labelling of food on voluntary or non voluntary basis could reduce emissions of greenhouse gases however there is limited empirical evidence on the influence of such labels on consumer purchases the purpose of this study was to investigate whether voluntary carbon labelling affects the demand for milk a randomized field experiment was conducted in 17 retail stores in sweden where a sign provided consumers with qualitative information about the carbon impact of climate certified milk the results suggest that the sign increased the demand for the climate certified milk by approximately 6 8 and the result is robust to alternative model specifications the effect is entirely driven by large stores such as supermarkets we find no statistically significant impact on total milk sales and the dataset is too small to verify the consequences for other milk brands the effect on the demand for the labelled milk is short lived

voting for environmental policy under income and preference heterogeneity we examine the design of policies for promoting the consumption of green products under preference and income heterogeneity using organic food products as an example two instruments are considered a price subsidy for the organic food products and a tax on the conventional products under income disparity consumers with high income always prefer a socially optimal subsidy to a socially optimal tax while low income consumers prefer a tax on conventional products when environmental policy is determined by the median voter the policies implemented tend to be stricter than socially optimal policies if income differences are large

how national culture and ethics matter in consumers green consumption values abstract going green in consumption is gaining momentum globally but little is known how national cultural values and consumers ethical ideologies explain green consumption with a culturally rich sample of 1929 responses from consumers in finland germany portugal and the united kingdom the present study examines how cultural long term orientation and collectivism predict consumers green consumption values and if these relationships are moderated by ethical ideologies the study finds that cultural collectivism has a significant positive effect on green consumption values as expected however the results show that the two long term orientation constructs namely planning and tradition point in opposite directions when predicting green consumption we demonstrate that while long term planning has a significant positive effect on green consumption values the effect of traditional values is negative we further show that this negative effect varies across consumers ethical ideologies so that the effect is the greatest for exceptionists and absolutists that is those who rely in their actions on universal moral principles rather than particular circumstances therefore our research contributes to the literature by providing new evidence for the cultural and ethical aspects in green consumption values furthermore the study suggests that managers pay special attention to the consumers who have high collectivistic and future oriented values to promote environmentally friendly consumption

effects of label information on consumer willingness to pay for food attributes choice experiments ces are often used to elicit consumer willingness to pay wtp for food attributes a concern about these approaches is that food attributes provided to respondents are assumed independent of attributes not provided we use surveys containing a series of ces to investigate effects of adding beef steak attributes wtp for important attributes in the ces decrease when the number of attributes increases from three to four while wtp increases when the number of attributes increases from four to five changes in wtp for attributes depend on their relationships with newly added attributes and the number of attributes presented copyright 2007 oxford university press

decision making governance for purchases of solar photovoltaic systems in japan in this study we analyze the factors that affecting purchasing decision time for solar photovoltaic pv s in japan based on our survey consumers spend about 4 months to make purchase decision also our estimation results show that information and knowledge that consumers obtained from the neighborhood and elsewhere make consumers more careful in their decision making and extend the purchase decision on the other hand experts on the advantages and disadvantages of installation shortened the decision time the situation and environment of each household in terms of income family size and the way of purchase of new homes have influenced on the decision to purchase a pv system in addition the availability of feed in tariffs was highly correlated with purchasing motivation but unexpectedly the capital subsidy programs have either little impacts or even delayed impacts on the purchasing timing
