compensation and rewards for environmental services cres and efficient design of contracts in developing countries behavioral insights from a natural field experiment the use of economic incentives for biodiversity mostly compensation and reward for environmental services including payment for es has been widely supported in the past decades and became the main innovative policy tools for biodiversity conservation worldwide these policy tools are often based on the insight that rational actors perfectly weigh the costs and benefits of adopting certain behaviors and well crafted economic incentives and disincentives will lead to socially desirable development scenarios this rationalist mode of thought has provided interesting insights and results but it also misestimates the context by which real individuals come to decisions and the multitude of factors influencing development sequences in this study our goal is to examine how these policies can take advantage of some unintended behavioral reactions that might in return impact either positively or negatively general policy performances we test the effect of income s origin low effort based money vs high effort based money on spending decisions necessity vs superior goods and subsequent pro social preferences future pro environmental behavior within madagascar rural areas using a natural field experiment our results show that money obtained under low effort leads to different consumption patterns than money obtained under high efforts superior goods are more salient in the case of low effort money in parallel money obtained under low effort leads to subsequent higher pro social behavior compensation and rewards policies for ecosystem services may mobilize knowledge on behavioral biases to improve their design and foster positive spillovers on their development goals

seeking sustainability discourses with q methodology abstract this paper outlines the potential benefit of q methodology for the study of environmental issues within ecological economics based on research into lets local employment and trading systems in the united kingdom q methodology is a qualitative but statistical approach to enable the discovery of a variety of discourses concerning how individuals understand their behaviour and how they understand the social and environmental worlds in which they live q methodology thus has the capacity to allow a more effective form of policy making and implementation process the paper introduces some of the basic tenets of q methodology illustrates these with results drawn from the study mentioned above and concludes by indicating the potential this methodology holds for ecological economics research

from malthusian stagnation to modern growth this paper investigates the historical evolution of the relationship among population growth technological change and standard of living the analysis focuses on two most important differences among the malthusian regime post malthusian regime and modern growth regime these were the behavior of income per capita and the relationship between the level of income per capita and the population growth rate the modern growth regime is characterized by steady growth in both income per capita and the level of technology in the malthusian regime technological progress and population growth was glacial by modern standards and income per capita was fairly constant in contrast to the modern growth regime the relationship between per capita income and population growth in the malthusian regime was positive post malthusian regime shared one characteristic with each of the two regimes in addition this paper developed and described an endogenous growth model consistent with the above mentioned transition process

the transfer efficiency and trade effects of direct payments all the different ways governments use to provide financialsupport to farmers can potentially distort trade and reduce net economic welfare however there are some types of support that are less trade distorting and more efficient than others this article reports the results of an analysis that examined different policy measures providing support to crop producers to rank them in terms of their effects on a selection of indicators with a particular focus on trade distortion and income transfer efficiency 1 we begin with an analysis of the differences in policy impacts among the three main categories of support provided to crop producers in oecd countries market price support payments based on land use and payments based on use of purchased inputs oecd 2001c that analysis is based on a two region model of equilibrium in the world market for a representative crop analytical solutions to this modelare devel oped to compare the production trade and income effects of the different support measures following procedures used in cahill and in moro and sckokai comparisons are of impact ratios using market price support as the reference category these ratios measure the effect on production trade or farm income of a given joe dewbre jesus anton and wyatt thompson are economists in the agricultural directorate of the organization for economic cooperation and development where the underlying analysis was undertaken the views expressed are our own and not necessarily those of the oecd secretariat or its member countries we thank our secretariat colleagues ken ash carmel cahill wilfrid legg and michele patterson for helpful comments on an earlier draft and stephane guillot for computer programming assistance this article was presented in a principal paper session at the aaea annualmeeting chicago il august 2001 the articl es in these sessions are not subjected to the journal s standard refereeing process 1

payments for pioneers revisiting the role of external rewards for sustainable innovation under heterogeneous motivations abstract acknowledging the diversity of preferences goals and motivations of individuals is key to promote the effectiveness of incentive based conservation interventions this paper analyses the heterogeneity of motivations to adopt silvopastoral practices a social ecological innovation for soil conservation and carbon emission reduction we use q methodology to identify smallholders views with regard to these practices in a community in the forest frontier in chiapas mexico the analysis uncovers three main perspectives self sufficient pioneers environmentally conscious followers and payment dependent conservatives we discuss these perspectives around three topics smallholders predisposition to adopt silvopastoral practices their views about needing external payments to sustain their livelihood and the diffusion of innovative sustainable practices we relate these perspectives with livelihood characteristics and with observed adoption levels under a pilot programme to promote silvopasture our findings suggest that incentives other than payments may be more appropriate for those more likely to adopt and that payments could encourage rent seeking strategies and not necessarily promote permanent behavioural change we suggest ways for designing more effective and adaptive environmental conservation programmes to foster adoption and continuation of social ecological innovations

replacement of agricultural price supports by area payments in the european union and the effects on pesticide use this article determines the contribution of recent european union agricultural policy reforms on the use of pesticides our theoretical model extends the multioutput generalization of the lichtenberg zilberman damage control technology model developed by chambers and lichtenberg our empirical analysis uses farm level data for a sample of french farms results suggest that price effects on the use of pesticides are always more elastic than area payment effects this indicates that policy reforms consisting of a reduction in price supports in favor of area payments may reduce application of crop protection inputs such policy changes which represent a certain degree of decoupling took place under the 1992 common agricultural policy reforms

from rent seeking to human capital a model where resource shocks cause transitions from stagnation to growth we present a growth model where agents divide time between rent seeking in the form of resource competition and working in a human capital sector the latter is interpreted as trade or manufacturing rent seeking exerts negative externalities on the productivity of human capital adding shocks in the form of fluctuations in the size of the contested resource the model can replicate a long phase with stagnant incomes and high levels of rent seeking interrupted by small failed growth spurts eventually followed by a permanent transition to a sustained growth path where rent seeking vanishes in the limit the model also generates a rise and fall of the so called natural resource curse before the takeoff an increase in the size of the contested resource has a positive effect on incomes shortly after the takeoff the effect is negative and on the balanced growth path the growth rate of per capita income is independent of resource shocks les auteurs presentent un modele de croissance ou les agents divisent leur temps entre la chasse aux rentes sous la forme de concurrence pour la ressource existante et le travail productif dans le secteur du capital humain cette derniere activite peut se faire dans le commerce ou le secteur manufacturier la chasse aux rentes a des effets externes negatifs sur la productivite du capital humain si l on injecte des chocs prenant la forme de fluctuations dans la taille de la ressource contestee le modele peut generer une longue periode durant laquelle les revenus stagnent et le niveau de chasse aux rentes est eleve periode interrompue par des petits sursauts de croissance qui tournent court et suivie eventuellement par une transition permanente a un sentier de croissance soutenue ou a la limite les activites de chasse aux rentes disparaissent le modele genere aussi l apparition et la disparition de la malediction des ressources naturelles avant que la croissance prenne son envol un accroissement de la taille de la ressource contestee a un effet positif sur les revenus peu apres le decollage l effet est negatif et sur le sentier de croissance equilibree le taux de croissance des revenus per capita est independant des chocs sur la ressource

the fischler reform of the common agricultural policy and agricultural land prices based on 7 300 agricultural land sales transactions we estimate the effect of the 2003 reform of the e u common agricultural policy on land prices as opposed to the main body of the literature on agricultural land values we do not start from a demand oriented net present value approach or hedonic pricing method but derive our reduced form pricing equation from a spatial land sales market model our empirical model accounts for spatial dependence and endogeneity of explanatory variables a reduction of payments by 50 ha would decrease land sales prices by 445 ha before and by 984 ha after the reform jel q15 q18

some neglected social costs of government spending in farm programs economic welfare analyses of farm programs typically assume that the direct social opportunity cost of subsidy payments is one dollar per dollar of government spending recent literature suggests that the marginal opportunity cost of a dollar of u s federal government spending is more likely to be in the range of 1 20 to 1 50 this implies that the net social costs of farm programs that involve government spending are significantly greater than the typical estimates in addition the normative efficiency ranking of alternative policies is sensitive to the marginal opportunity cost of government spending

impact of policies and subsidies in agribusiness the case of oil palm and biofuels in colombia abstract we analyze the economic impacts of policies supporting biodiesel production in colombia such as subsidies and mandates for compulsory fuel mixtures in the major biodiesel source being palm oil we seek to establish the impact of these policies on oil palm producer incomes prices and production levels of crude palm oil cpo and biodiesel as well as the impacts on demand for land for oil palm plantation expansion we also calculate the so called deadweight costs to account for the social costs derived from the inefficiencies of government interventions in the biodiesel markets the analysis is done using a partial equilibrium models for the two interrelated sectors the production of palm oil and biodiesel and the demand for new land needed to cope with the additional palm oil needed the model was calibrated for 2009 to simulate for the 2010 2020 period the results of the simulations reveal that the subsidies alone are themselves not effective tools to achieve the government objectives defined in the biofuels program in colombia subsidies need to be complemented by increased blending mandates to ensure that palm cultivation and production of biodiesel investments are profitable enough that producers would bet on such business additionally we find that producers of palm oil benefit most from subsidies in the short term however in the long term it is the biodiesel entrepreneurs who will appropriate the larger share of growth revenue of the entire production chain the social costs of the biofuels program are small in the short term and represent only between 0 2 and 0 7 of the tax expenditure however in the long term they would become significant and would account for around 4 1 to 6 1 of the tax payers expense

the degree of decoupling of area payments for arable crops in the european union in 1992 the common agricultural policy cap of the european union eu significantly changed direction in the arable crop sector with the so called macsharry reform this reform which reduced cereal intervention prices eliminated output payments for oilseeds and introduced per hectare compensatory payments and a compulsory set aside requirement attached to these payments implied a significant change in the policy incentives to produce in 1999 intervention prices were cut further bringing them closer to world market levels as well as aligning payments of cereals and oilseeds the most recent reform in

measuring heterogeneous preferences for preserving farmland and open space abstract public preferences for environmental policies often vary among individual citizens according to their socio economic characteristics and attitudes toward environmental programs most researchers account for socio economic characteristics when conducting public preference surveys but do not account for differences in preferences that transcend socio economic categories identifying the public s attitudes regarding environmental programs and the role they play in shaping individuals preferences for policy alternatives can assist policy makers in developing programs that are consistent with public expectations this paper uses factor analysis and a discrete choice model to describe differences in public preferences that result from different attitudes regarding the goals of programs designed to preserve farmland and open space results describe policy implications that are not apparent when using models that address socio economic characteristics alone

adoption of organic farming are there differences between early and late adoption based on the fact that not all farmers adopt a technology at the same time it is argued in this paper that the distinction between groups is important because early medium and late adopters respond differently to economic and non economic factors when they consider whether to take up organic farming or not the individual effects on adoption between the groups are identified by the use of multinomial logit analysis the results provide evidence that there are significant differences in the characteristics between the adopter groups the findings also reveal that the factors that affect adoption play a different role for early medium and late adopters particularly with regard to farming intensity age information gathering as well as attitudes of the farmer more specifically early adopters were the youngest to adopt organic farming and their decisions were found to be less profit related compared to other groups late adoption is constrained by risk considerations while environmental attitudes and social learning were identified to be important determinants for all adopter groups overall the findings strongly suggest that for policy measures to be effective the current state of diffusion has to be taken into account

multiple policy goals in a trade model with explicit factor markets as trade protectionism has been reduced through multilateral agreements concerns have been raised about competitiveness effects of cross country differences in environmental and labor standards costs associated with decreased competitiveness are distributed across consumers and the various providers of inputs used in the production of affected commodities in this paper we present a trade model which can be used to help quantify the magnitude and distribution of costs associated with changes in input regulations the model can also be used to identify levels of policies required to offset or redistribute costs associated with regulations which reduce international competitiveness

how not to pay field experimental evidence on the design of redd payments abstract payments for ecosystem services pes can use many design features we investigate the impact of payment conditionality types i e different specifications when to pay and when not to pay for pes on deforestation and agricultural production in a lab in the field experiment our experiment also tests variations in contract period and payment volatility we designed a highly visual simulation game to characterize the decision situation of a cattle rancher in brazil the player can expand extensive pasture by deforestation or intensify existing pasture the model includes both a land and a capital constraint we applied the game in an economic framed lab in the field experiment in tocantins brazil payments conditional on forest carbon stock lead to slow but steady deforestation while payments conditional on forest carbon stock change suppressed deforestation more strongly but payments conditional on stock increase cattle production while payments conditional on stock change have no effect on production thus depending on the level of leakage either type of conditionality can be more cost effective in reducing global carbon emissions contracts with limited periods lead to strong deforestation after the end of the payment period payment volatility had no significant effect

does structure matter the impact of switching the agricultural policy regime on farm structures abstract this paper investigates the relationship between structural change in agriculture and a policy regime switch at the regional level using the agent based spatial and dynamic simulation model agripolis we simulate structural change for two different farm structures in response to a policy change results show that structural adjustment differs depending on the initial structure

geography health and the pace of demo economic development abstract this paper investigates the impact of subsistence consumption and extrinsic and intrinsic causes of child mortality on fertility and child expenditure it offers a theory for why mankind multiplies at higher rates at geographically unfavorable tropical locations placed into a macroeconomic framework this behavior creates an indirect channel through which geography shapes economic performance it is explained why it are countries of low absolute latitude where we observe exceedingly slow if not stalled economic development and demographic transition

the willingness to adopt agro ecological innovations application of choice modelling to caribbean banana planters this paper proposes an ex ante evaluation of the willingness to adopt agro ecological innovations aimed at reducing pesticide use for banana production in the french west indies four innovative systems including intercropping improved fallow and new pest tolerant varieties are proposed to a sample of 607 planters with innovation and policy attributes calibrated from a bio economic farm model the model interacts technological and economic innovation attributes with farmer individual factors and allows for a dual source of unobserved heterogeneity we estimate a system of random coefficient logit models to obtain marginal values of innovation traits that can be useful for targeting farm types with appropriate innovations and designing policies for securing agricultural revenue

how useful is the pse in determining agricultural support the support of the agricultural sector in developed countries plays a major role in the international policy agenda the producer support estimate pse is one of the best known measures which has been developed by oecd and is used all over the globe in the pse all types of support are aggregated and one of the main components 70 at oecd level is the market price support mps here we show by means of characteristic examples that the mps has no clear relation to basic economic measures determining support for producers as a consequence of policy intervention the mps overestimates the consequences of tariffs and export subsidies and underestimates the consequences of quota systems in determining producer support misperception of the size and directions of support may affect policy decision making wrongly the paper indicates that weighted average producer prices corrected for quantity restrictions may be more useful than the reference prices and quantities used by oecd

paying for the hydrological services of mexico s forests analysis negotiations and results abstract mexico faces both high deforestation and severe water scarcity the payment for hydrological environmental services psah program was designed to complement other policy responses to the crisis at the interface of these problems through the psah the mexican federal government pays participating forest owners for the benefits of watershed protection and aquifer recharge in areas where commercial forestry is not currently competitive funding comes from fees charged to water users from which nearly us 18 million are earmarked for payments of environmental services applicants are selected according to several criteria that include indicators of the value of water scarcity in the region this paper describes the process of policy design of the psah the main actors involved in the program its operating rules and provides a preliminary evaluation one of the main findings is that many of the program s payments have been in areas with low deforestation risk selection criteria need to be modified to better target the areas where benefits to water users are highest and behavior modification has the least cost otherwise the program main gains will be distributive but without bringing a pareto improvement in overall welfare

the innovation effects of environmental policy instruments a typical case of the blind men and the elephant abstract in this paper we examine the innovation effects of environmental policy instruments in four literatures theoretical models on incentives for eco innovation econometric studies based on observed data survey analysis based on stated information and technology case studies the aim of this paper is to critically examine the methods and the results we argue that the case studies literature even when its results are specific and difficult to generalise is a necessary source of empirical evidence about policy impacts and the factors responsible for these impacts pointing to issues that are neglected in the theoretical and econometric literature such as the specifics of the innovation context and policy interaction effects the paper states five synthesised findings and makes a plea for multi method analysis one other important synthesised finding is that the influence of market based instruments on innovation such as emission trading and taxes is far weaker than assumed

how much do decoupled payments affect production an instrumental variable approach with panel data how much decoupled payments such as direct payments in the u s affect agricultural production remains an open empirical question with implications for policy using data from multiple years of the census of agriculture we exploit a provision of the 2002 farm act that departed from previous policy by making oilseeds eligible for direct payments thus increasing payments to areas that historically produced more oilseeds our instrumental variable estimates in contrast to ols estimates suggest that changes in payments over the period 2002 to 2007 had little effect on aggregate production at the zip code level copyright 2012 oxford university press

the effects of farm subsidies on farm exports in the united states we estimate the elasticity of u s farm exports to u s farm subsidies using a gravity model of state level farm exports to 100 major trading destinations for the period 1999 to 2011 our identification strategy exploits the within state variation that is free of endogeneity bias in the levels and trends of farm subsidies and farm exports we find that a 1 decrease in farm subsidies would reduce u s farm exports by 0 40 per annum this equivalently means that the complete abolishment of the farm subsidy program would reduce u s farm exports by approximately 15 3 billion per year importantly we document robust evidence that amber box subsidy programs such as counter cyclical payments and marketing loan gains have the strongest effect on farm exports while green box subsidy payments such as direct payments have negligible effects finally subsidy payments affect exports only in agricultural commodities not in livestock our subsidy elasticity estimates are statistically significant stable and economically meaningful and are vitally needed by u s and global policymakers in the face of critical domestic and international developments

mortality decline human capital investment and economic growth abstract we examine the role of increased life expectancy in raising human capital investment during the process of economic growth we develop a continuous time overlapping generations model in which individuals make optimal schooling investment choices in the face of a constant probability of death we present analytic results followed by results from a calibrated version of the model using realistic estimates of the return to schooling mortality decline produces economically significant increases in schooling and consumption allowing schooling to vary endogenously produces a much larger response of consumption and capital to mortality decline than is observed when schooling is held fixed

unraveling the effects of payments for ecosystem services on motivations for collective action this paper addresses the differential impacts on decisions towards collective action in the context of payments for ecosystem services pes where individual and collective rewards are conditional on a minimum collective conservation level being achieved interactions between the different reward types farmers social preferences social ties and communication are identified a field game experiment is conducted with andean farmers in peru and framed around their decisions to conserve agrobiodiversity as an impure public good the main results are that pes schemes could be effective in motivating collective action for agrobiodiversity conservation and that individual rewards are likely to be more effective and less sensitive to social factors than collective rewards the latter might have a positive effect on conservation when they are shared within socially closely related groups or in situations where communication and deliberation about collective action are possible

from malthus to modern growth can epidemics explain the three regimes we model demographic and economic long run development in a setting where mortality is endogenous and subject to epidemic shocks the model replicates the full transition from malthusian stagnation to modern growth consistent with the historical facts the economy also passes an intermediate post malthusian phase where growth rates of both population and per capita income increase simultaneously as mortality rates fall and become less volatile the escape from the malthusian trap is the result of a series of mild epidemic shocks making it inevitable at some stage but its timing random calibrations show that it can differ by thousands of generations absent differences in exogenous parameters

understanding the uptake of organic farming accounting for heterogeneities among irish farmers abstract this paper examines the decisions of irish farmers to convert to organic farming by applying the theory of planned behaviour to control for social influence and technical constraints cluster analysis and principal component analysis are utilised to account for sample heterogeneity and to identify heterogeneities in farmer beliefs regarding adoption of organic methods the results indicate that the impact of economic incentives and technical barriers varies while social acceptance of organic farming constrains adoption these findings suggest that policy incentives mainly based on subsidy payments may be insufficient to increase the organic sector in the presence of social and technical barriers

mortality and early growth in england france and sweden we set up a stochastic open economy growth model with endogenous fertility and mortality a three country version of the model is calibrated to pre industrial mortality data from england france and sweden by fitting parameters to match observed rates of correlation in mortality rates the model can also account for differences in both the volatility of mortality rates and the timing of the industrial revolution

motivation crowding in environmental protection evidence from an artefactual field experiment abstract this paper examines how motivation crowding and social image affect environmental conservation decisions an artefactual field experiment conducted in bolivia is used to reproduce the trade off between individual and social benefits in natural resource use and test the effect of non monetary and non regulatory incentives on pro social behavior for environmental conservation the results show the presence of a social norm prescribing positive contribution towards environmental protection and that external incentives have heterogeneous effects on pro social behavior depending on how they influence reputation and self image the experimental results differ from those of analogous experiments conducted in the laboratory and are instead consistent with those from field experiments on common pool resource management this fact suggests caution in generalizing conclusions reached in the laboratory to different settings and populations

the production effects of agricultural income support policies under uncertainty this analysis decomposes the production impacts of income support programs into wealth insurance and coupling effects under the usual assumptions about preferences the wealth and insurance effects of many support programs increase optimal input levels even for supposedly decoupled programs if the program is coupled in the usual sense then all three effects often act in the same direction it is concluded that studies of trade and domestic policy reform in stochastic environments should consider insurance and wealth effects the derivative conditions required to obtain results are also subjected to scrutiny simulations for an iowa corn producer confirm the comparative statics

one size fits all policy instruments should fit the segments of target groups abstract in order to meet the kyoto co2 reduction targets technical innovations in the field of energy efficiency must diffuse more rapidly into a larger market however markets develop gradually especially if innovations are involved diffusion starts with the early market innovators and early adopters followed by the mainstream market the early and late majority and ends with the laggards the actors in these markets differ in their willingness to adopt innovations the early market actors have a visionary attitude and the mainstream market actors are more pragmatic in order to choose policy instruments that will most effectively influence these two markets within the target group of housing association we addressed the following two questions 1 what are the differences between the early and mainstream market actors from a behavioural change point of view 2 in what way do existing policy instruments differ in influencing the behaviour of these actors we analyzed early market and mainstream decision making behaviours and how the active ingredients in policy instruments specifically target the characteristics of the two markets mainstream instruments should intervene as early as possible in the decision making process and emphasize communication about advantages such as comfort and quality in addition to money and energy savings furthermore they should present energy conservation as a solution to an actual problem instead of bureaucratic subsidy systems for the mainstream the motto should be cash on the barrel head early market actors are highly internally motivated implying that early market interventions have to be challenging and facilitating

transfer efficiency and distributional impacts of u s farm support evidence from a macro micro simulation the objective of this analysis is to provide insight into the transfer and distributional efficiency of farm support policies a one shot macro micro simulation model weaves together the two prominent threads in the agri cultural decoupling literature that focuses for the first part on economy wide impacts and for the second on the role of cross household het erogeneity experimental shocks to output and land subsidies that generate a 1 increase in net national farm income are compared for the united states with output subsidies shown to have lower transfer efficiency but comparable distributional impact surprisingly a more cou pled approach to policy whereby some agricul tural enterprises are excluded from program participation is found to generate a stronger reduction in inequality this is partially at tributed to the inclusive definition of a farm

malthus to solow a unified growth theory is developed that accounts for the roughly constant living standards displayed by world economies prior to 1800 as well as the growing living standards exhibited by modern industrial economies our theory also explains the industrial revolution which is the transition from an era when per capita incomes are stagnant to one with sustained growth the authors use a standard growth model with several technologies the first denoted the malthus technology requires land labor and reproducible capital as inputs the second denoted the solow technology does not require land the authors show that in the early stages of development only the malthus technology is used and due to population growth living standards are stagnant despite technological progress eventually technological progress causes the solow technology to become profitable and both technologies are employed at this point living standards improve since population growth has less influence on per capita income growth in the limit the economy behaves like a standard solow growth model excerpt

long term crop productivity response and its interaction with cereal markets and energy prices abstract crop yields are endogenous as long as economic agents adjust to permanent changes in expected prices the literature however does not offer a definitive value of how much yield would change in response to sustained price changes to fill the gap we use available scientific findings and data to estimate yield elasticities that enable agricultural commodity and food policy analysis using a world market model with short to long run yield response we show the impacts of sustained energy price shocks on global cereal supply and demand the results highlight substantial differences in quantity and price effects depending on the yield elasticities these results demonstrate the need to recognize yield response when assessing impacts of energy prices or biofuel production on food uses or more generally on food security in the face of income and population growth evolving dietary patterns climate change implications or other long run pressures

reconciling theory and practice an alternative conceptual framework for understanding payments for environmental services article i nfo this article provides an alternative and novel theoretical approach to the conceptualization and analysis of payments for environmental services pes we devote special emphasis to institutional and political economy issues which have been somewhat neglected in the literature on pes we argue that the coasean and pure market approach dominating the conceptualization of pes in the literature cannot be easily generalized and implemented in practice by contrast taking into account complexities related to uncertainty distributional issues social embeddedness and power relations permits acknowledging the variety of contexts and institutional settings in which pes operate the alternative approach presented in this introductory article to the special section may be more appealing to pes practitioners since while avoiding restrictive and prescriptive standpoints it allows some key sources of complexities they usually deal with on the ground to be more easily understood

farmers adoption of integrated crop protection and organic farming do moral and social concerns matter we investigate empirically the role of moral and social concerns in farmers decision to adopt integrated crop protection ip and organic farming of a survey questionnaire has been sent to 1286 fruit growers and vegetable producers located in the french areas of alpes de haute provence hautes alpes and vaucluse analysis of individual responses n 243 shows that although economic concerns play a strong role a significant number of respondents give high importance to moral and social ones we also examine how these considerations matter according to different crop protection strategies that is conventional farming ip and of using a multinomial logistic regression we find that 1 social concerns e g showing to others one s environmental commitment drive both ip and of adoption 2 moral concerns e g do not feel guilty about one s choices increase the probability of organic farming adoption only and 3 farmers who give high importance to economic concerns e g cutting production costs are less likely to adopt of

credit market imperfections and the distribution of policy rents this article shows that credit market imperfections have important implications for the distribution of policy rents in a model with land as fixed factor and credit market imperfections when an area payment is given land rents go up by more than the subsidy on aggregate farms may lose from the subsidy the results depend on the extent to which subsidies have direct and indirect effects on the credit constraints on whether farms rent or own land and on farm heterogeneity

payments for environmental services in watersheds insights from a comparative study of three cases in central america we have compared three cases of payments for water related environmental services pes in central america in terms of socioeconomic background opportunity costs of forest conservation and stakeholders perceptions of the conditions of water resources and other issues we found that in general the opportunity costs are larger than the amounts paid which apparently contradicts the economic foundation of pes schemes and suggests that the role of intangibles is important in inducing participation the results also show that trade offs between different environmental and social goals are likely to emerge in pes schemes posing some doubts as to their ability to be multipurpose instruments for environmental improvement and rural development we also found that pes schemes may work as a conflict resolution instrument facilitating downstream upstream problem solving though at the same time they might introduce changes in social perceptions of property rights

negotiating reductions in agricultural support implications of technology and factor mobility this paper highlights the joint significance of agricultural technology and factor mobility in determining the impact of changing support policies the impact of across the board reductions in farm support on output exports employment and land values will vary systematically across countries depending on their relative reliance on export output and input subsidies furthermore considerable maneuvering room exists even after an aggregate reduction in support is agreed upon for example the aggregate u s producer subsidy equivalent could be reduced while leaving unchanged the demand for farm labor by shifting the mix of remaining subsidies toward inputs which are complementary

exploring the links between equity and efficiency in payments for environmental services a conceptual approach this paper addresses the relationship between equity and efficiency in pes schemes from a conceptual point of view emphasis is placed on the role of the institutional setting social perceptions about economic fairness or distributive justice of the payments uncertainty and interactions between agents including power relations we introduce the heuristic concept of the efficiency equity interdependency curve to illustrate potential combinations between equity and efficiency that may be theoretically possible the paper argues that different types of institutional factors determine which equity efficiency combinations may be potentially feasible influence the actual combination that will be achieved on the ground and condition possible changes in that combination due to exogenous factors by stressing the role of institutional aspects in shaping the equity efficiency relationship the paper attempts to go beyond the dominant coasean vision of pes
