an environmental performance index for products reflecting damage costs abstract several studies have demonstrated how to use dea data envelopment analysis based techniques to estimate environmental performance indices none of these studies however are taking information on the environmental damage costs of the pressure types considered into account this study is bridging a gap between environmental indices founded in physical pressures and damage costs founded in welfare economics the aim of the paper is twofold first to demonstrate how to implement the information on environmental damage costs within a dea based environmental performance index and second to estimate these indices at product level by using danish input output data and environmental data from 1997

calculating levels of protection is it always appropriate to use world reference prices based on current trading status abstract protection measures such as the nominal protection coefficient npc the effective protection coefficient epc the producer subsidy equivalent pse and the consumer subsidy equivalent cse are conventionally calculated using world reference prices based on current trading status under certain conditions the conventional approach can lead to incorrect estimation of the degree and sometimes even the direction of protection this paper spells out the conditions under which use of world reference prices based on current trading status is incorrect and presents data for wheat in pakistan to illustrate how failure to consider these conditions can lead to misleading policy recommendations

efficiency analysis for exogenously fixed inputs and outputs we evaluate by means of mathematical programming formulations the relative technical and scale efficiencies of decision making units dmus when some of the inputs or outputs are exogenously fixed and beyond the discretionary control of dmu managers this approach further develops the work on efficiency evaluation and on estimation of efficient production frontiers known as data envelopment analysis dea we also employ the model to provide efficient input and output targets for dmu managers in a way that specifically accounts for the fixed nature of some of the inputs or outputs we illustrate the approach using real data for a network of fast food restaurants

simple analytics of segmented markets what case for liberalization abstract discussion about the liberalization of controlled markets in developing countries frequently assumes that the removal of price or quantity restrictions will lead rapidly to increased marketed output however when parallel markets exist market controls may not depress marketed output and may actually increase it conversely liberalization may not increase marketed output much if at all the benefits of liberalization will be greater where parallel markets are costly to enter so that decontrol increases efficiency and scarce resources such as entrepreneurial and administrative ability are diverted into the rent seeking activity of gaining access to illegal parallel markets this paper employs partial equilibrium techniques to analyze market controls and liberalization in the presence of parallel markets for foodgrains credit labor and foreign exchange

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

agriculture s environmental externalities dea evidence for french agriculture the existence of persistent technical inefficiency offers the opportunity for a free lunch not typically implied by the neoclassical theory of the firm when external effects are related to the use of particular inputs reduction of persistent technically inefficient levels of input use represents a means of reducing external impacts an important example is found in agriculture where substantial environmental impacts are generated by particular inputs within this context this paper considers the usefulness of data envelopment analysis dea for estimation of potential input reductions and assessment of potential reductions of environmental impacts of agricultural inputs an application for french cereal production provides estimates that indicate that substantial potential exists for reduction of input use and environmental impacts

agricultural productivity of the spanish regions a non parametric malmquist analysis productivity growth for the agricultural sectors of the 17 spanish regions over the period 1977 88 is studied using non parametric programming techniques productivity changes based on conventional inputs are linked to other economic geographic and institutional issues average technical change in the spanish regions grew at an annual rate of 2 9 but with great regional variation this paper presents a clear characterization of areas with greater technical progress and the regions with technical regress

processing and preparation costs for rice and coarse grains in urban mali subjecting an ipse dixit to empirical scrutiny abstract this article uses household survey data from bamako mali to address three questions important in the policy debate concerning the determinants of the substitution from coarse grains to rice in west african diets and policy options the questions are 1 what are the relative costs of rice and coarse grain based dishes with and without complementary sauce costs 2 what are the shares in total cost of individual processing and preparation stages 3 are pre processed coarse grains e g dehulled grain or flour cheaper to consume than coarse grains processed in the household contrary to prevailing opinion the paper shows that despite higher processing costs coarse grain based dishes are cheaper than rice based dishes the main contributory factors to the higher cost of rice based dishes are sauce cost cereal cost and preparation cooking and sauce preparation time the result holds true over a wide range of rice and coarse grain prices and opportunity costs of women s time suggesting that the finding applies more generally to the urban sahel and not just bamako moreover coarse grain based dishes need not take longer to process and prepare than rice based dishes if the dehulling step is mechanized however pre processed coarse grains are not competitive with household processing given present technology and opportunity costs of women s time nor will coarse grains be able to retain the extent of their cost advantage over rice as incomes and labor opportunity costs rise without improvements in the efficiency of processing services

optimal grain pricing and storage policy in controlled agricultural economies application to zimbabwe abstract maize pricing and storage policies of zimbabwe s grain marketing board are compared to those that would be optimal under certain objective function risk and risk aversion assumptions optimal producer prices and storage levels are found to be interdependent and to respond to prices at other levels of the marketing chain the ideal maize reserve stock increases with uncertainty over import transportation costs a factor to consider in light of the threat of south african sanctions but at a reasonable risk aversion level optimal reserves still are much lower than those presently held by the board

an improved maize marketing system for african countries the case of zimbabwe abstract access to food is essential to survival and access to markets is essential for development most parastatal marketing systems in africa have failed either to provide adequate links between surplus and deficit areas or to extend markets to scattered smallholders or both the parastatal system does provide a legitimate need but it has been frequently misapplied this article proposes a system for zimbabwe which retains government control of national stocks and enables the parastatal to stabilize prices at the same time ensuring a more rational delivery system in rural areas with prices reflecting storage and transport costs the local population is encouraged to fulfill local needs thus avoiding the expense of directing all marketing and processing through the urban areas a more localized system will also have greater multiplier effects

macroeconomic adjustment and human nutrition abstract the macroeconomic adjustments made by most developing countries over the past decade to cope with economic crises have in many cases had severe effects on the poor these effects have often been ignored in planning but it is important to address them both to avoid human suffering and to facilitate economic growth this article provides a brief synthesis of current knowledge about the short term effects of macroeconomic adjustment policies on the nutritional status of the poor and proposes action to improve the nutrition effects of future adjustment programmes

regional welfare disparities the case of the european union the regional welfare distribution in the european union between 1993 and 1998 is examined using several complementary methodologies the results obtained show a reduction in regional welfare disparities over the period analysed it is worth noting in this respect however that regional productivity differences prove to be the main determinant behind observed welfare inequality in the european context moreover there has also been a decline in regional bipolarization over the six year contemplated while the degree of observed intradistributional mobility is relatively low the empirical evidence presented nevertheless reveals the importance of variables such as the national component the spatial location the regional productive structure or the percentage of gdp devoted to investment or to r d expenditure in accounting for the dynamics of the distribution under analysis

public goods and private interests understanding non residential demand for green power this article presents the results of the first large scale mail survey of non residential green power customers in the united states the survey explored the motivations attitudes and experiences of 464 business non profit and public sectorcustomers that have voluntarily opted to purchase and frequently pay a premium for renewable electricity results of this study should be of value to marketers interested in targeting these customer segments to policymakers interested in fostering and understanding non residential demand for green power and to academics pondering the motivations for firms to engage in such voluntary environmental initiatives

economic versus environmental improvement potentials of danish pig farms this article demonstrates how economic and environmental improvement potentials of danish pig farms can be estimated using data envelopment analysis dea to avoid some of the problems associated with the definition of undesirable outputs environmental variables are included as nutrients applied with manure and nutrients removed with the crops these environmental variables are combined with a series of economic variables including the costs of fertilizer furthermore subvector efficiency and a two step analysis are used in order to consider economic and environmental technical efficiency separately the empirical results show considerable improvement potentials especially on the environmental variables sensitivity studies validate that these results are robust to possible uncertainties in the measurement of the environmental variables

sugar beet for bioethanol production an approach based on environmental agricultural outputs abstract the eu imports both bioethanol and the raw material needed to produce it thirty percent of bioethanol is produced from sugar beets in the eu however sugar beet cultivated area and yields have fallen due to the 2006 sugar regime reform given the potential uncertainty about the future for sugar beet farmers biofuels may represent an alternative market this paper analyses potential contribution to the efficiency in terms of environmental output of the sugar beet crop both when production is oriented toward bioethanol and regarding the use of input an empirical application is performed in spain by data envelopment analysis dea the results show that 4 of farms have full technical efficiency while the rest have an average efficiency of 55 9 the figures show that inputs can be reduced over 40 and also show the low average level of input use efficiency in addition it cannot be said that there is a relationship between efficiency and farm scale the consideration of aspects such as the environmental advantages of using sugar beet production for bioethanol can open new lines of action to support this crop in the eu in addition boosting sugar beet production may reduce potential dependency on importation

food marketing and pricing policy in eastern and southern africa a survey abstract this article surveys the empirical record of grain marketing and pricing policy in eastern and southern africa over 1930 1995 the paper addresses five key issues with major implications for food policy throughout africa a why the anticipated supply response to market liberalization has not yet occurred b why the common assumption of state taxation of farmers to support a cheap food policy does not apply in most of the countries in the region c why the temporary successes of the state led approach to stimulating smallholder grain production were unsustainable d why the elimination of government food subsidies associated with market reform has not adversely affected consumers and e why the fiscal cost of the marketing systems at least initially worsened rather than improved after the reforms were implemented in most countries the key future challenges for marketing policy are how to develop coordinated and financially sustainable input finance and commodity marketing systems for raising productivity growth in smallholder agriculture while overcoming inherited agricultural dualism and how to mitigate the effects of food price instability in a cost effective manner

is dualism still a source of convergence in europe this paper aims at assessing whether dualism represents a significant source of the aggregate labour productivity convergence observed across the european regions in the 1980s we use a model of the dual economy based on the work of dixit oxford economic papers 22 229 34 1970 and mas colell and razin oxford economic papers 25 72 79 1973 to obtain hypotheses to be tested in cross region growth regressions we use aggregate and sectoral data for 109 territorial units from 1980 to 1990 our cross section results are consistent with the major predictions of the dual model ignoring dualism as a source of convergence could therefore lead to inaccurate interpretations of the relative roles played by each of the forces behind the process and to inexact assessments of what actions should be taken if any by the european regional policy to help the process become more pervasive

choice of technology in small and large firms grain milling in tanzania abstract it is not uncommon to find many production units in low income labor abundant and capital scarce economies such as tanzania employing sophisticated and capital intensive production techniques in such circumstances a technology choice problem exists in the sense that the technologies in use and more often the products being produced are not compatible with the resource endowment of the economy and the income levels of the majority of the population this paper evaluates the relative performance of small and large scale grain milling techniques in tanzania to identify appropriate ones and explain why some firms select inappropriate techniques and products the consequences of technology choice are then discussed within the context of employment creation output expansion surplus generation skill formation economies of scale and overall resource use

maize food self sufficiency and policy in east and southern africa abstract in recent years maize has become a major food staple in the east and southern african region national average yields of maize remain low and yield gains are generally below population growth rates agricultural policy particularly maize pricing marketing and trade is examined and it is noted that despite an objective of maize self sufficiency many countries in the region continue to face erratic supplies finally a brief look is taken at the technologies available for maize and at those groups of smallholders who are unable to meet their annual household food requirements

agricultural price policy in tanzania abstract this paper examines agricultural price policy implementation and its strategic impact in tanzania over the period 1969 1980 trends in producer prices and the rural urban terms of trade are analysed by constructing weighted price and income indices for major categories of crops marketed through official channels the results indicate a substantial deterioration of real prices and incomes from crop sales during the 1970s when taken in conjunction with a concomitant deterioration in the efficiency of agricultural marketing the analysis suggests that price policy has had a major adverse impact both on peasant living standards and on the economic performance of tanzania since the mid 1960s

kenya s cereal sector reform programme managing the politics of reform abstract the political aspects of reform have been underplayed in structural adjustment programmes the problematic and inconsistent implementation of kenya s cereal sector reform programme csrp it is argued here is substantially the result of failing to manage the politics of reform good political management of the reform process would have included ensuring a clear understanding by interest groups of the likely consequences of liberalisation and full involvement of the president and cabinet from the outset in order to create an ongoing reform culture

the privatization of agricultural trading in malawi abstract this paper examines the privatization of smallholder agricultural output marketing in malawi despite problems with implementing the privatization program including serious disruptions in the supply of maize the staple food the move toward greater private sector involvement in agricultural marketing has been successful nonetheless several medium term development issues e g food security and buyer and seller of last resort functions need to be addressed in the context of relations between the marketing parastatal admarc and the private sector before the policy change can be regarded as fully successful

international regulations and environmental performance this article employs the data envelopment analysis dea approach to compute the environmental performance of all but two organisation for economic co operation and development oecd countries it is found that although the environmental performance of countries differs over time poland and hungary are the two best performers for all periods while italy japan austria and switzerland are ranked among the worst the effect of international regulations and some observed characteristics of countries on environmental performance are also investigated international regulations are reported to have a positive effect on environmental performance

zimbabwe s maize based green revolution preconditions for replication abstract the green revolution was launched in 1960 in zimbabwe five years before it got underway in india since zimbabwe s green revolution was spearheaded by white commercial farmers however it was ignored by africa s new leaders in the 1960s as they experimented with state farms from moscow communal farms from china and land settlement schemes from israel at zimbabwe s independence in 1980 the new majority ruled government introduced a number of programs to help smallholders increase food and cash crop production drawing on a backlog of hybrid maize varieties expanded access to credit higher guaranteed government maize prices and marketing subsidies smallholders doubled maize production during 1980 1986 zimbabwe s maize based green revolution challenges those who allege that hybrid maize cannot compete with sorghum in low rainfall areas and that it is unsuitable for resource poor farmers because of the need to purchase new seed each year today virtually 100 of zimbabwe s maize area is under hybrids and short season hybrids are outcompeting other foodgrains in many low rainfall areas zimbabwe s biggest challenge is to develop cost effective marketing policies and institutions to sustain its maize based green revolution countries trying to replicate zimbabwe s success story should focus on fulfilling four interrelated preconditions political technological economic and institutional

prosocial behavior private contributions to agriculture s impact on the environment private provision of public environmental benefits is considered with a theory of prosocial behavior that elaborates the roles of nonhedonistic values held by agents as well as the functional interaction between private good and public good production processes the theory also identifies the conditions under which public environmental goods will be privately supplied and motivates an empirical approach models of environmental effort in agriculture are estimated based on a survey of u s field crop farmers results confirm the role of hedonistic motivation of environmental effort and provide very weak evidence of a role of nonhedonistic values

landownership and the adoption of minimum tillage full owner operators and landowners with small holdings have lower minimum tillage adoption rates on cultivated cropland than do other landownership groups after accounting for land quality and regional location nonfamily corporate structure does not significantly influence the adoption decision these conclusions about minimum tillage adoption were obtained from a logit model using 7 649 cultivated cropland observations from across the united states this study indicates that small operating size poses more of an obstacle to minimum tillage adoption than does separation of ownership from farm operation

farmer risk assessment for voluntary insecticide reduction abstract we develop a theoretical basis for voluntary reduction in insecticide use and quantify the subjective value farmers place on reducing environmental risk the indirect utility model is used to quantify the acceptable financial cost of eliminating one insecticide application in return for avoidance of moderate risk to the environment the mean valuation in illinois iowa nebraska and ohio usa is 8 25 per acre acceptable yield loss increases with importance of environmental goods with formal education and with farming experience valuation increases with total expenditure on insecticides up to 89 per acre decomposition of the tobit model used in estimation indicates that voluntary programs should target intensification rather than extensification of participation to maximize effectiveness

developing a social perspective to farm performance analysis abstract this paper examines how traditional farm productivity analysis can be extended to produce a performance measure from the perspective of society a biophysical model is used to measure inputs from the environment which are combined with conventional marketed inputs to develop an environmentally sensitive malmquist productivity index to determine social productivity growth data envelopment analysis dea is used to analyze data collected from selected farms in south east australia and includes a measure of leaching and run off as a proxy measure of the impact the application of fertilizers has on ground and surface water the results show measured productivity growth increases for some farms and decreases for others when environmental factors are considered

regional mobility in the european union regional mobility in the spatial distribution of per capita income in the european union is examined over the period 1977 to 1999 the methodology used to investigate this issue combines a series of measures taken from the literature devoted to the dynamic study of personal income distribution with a non parametric analysis the results show limited mobility in the distribution considered and a decline in mobility over time the empirical evidence presented indicates moreover that mobility patterns vary as a function of regional development levels additionally the analysis carried out investigates the role played in explaining intra distribution mobility by variables such as per capita income population density per capita expenditure in investment market potential and the share in total employment of agriculture advanced services and non market services

distributional effects of maize self sufficiency in zimbabwe implications for pricing and trade policy abstract maize self sufficiency has normally been an explicit policy goal throughout eastern and southern africa because of the perception that it could be achieved at prices below import parity and that it contributes to rural income growth however this analysis based on household survey data from zimbabwe and the results of an econometrically based simulation model indicates that a pricing policy geared towards maize self sufficiency would mainly benefit a small set of well off farmers and require either greater subsidies or higher prices to consumers many of whom are low income rural farmers in low rainfall areas the broader implications of this analysis are that even if the producer price needed for self sufficiency is below import parity the pursuit of food self sufficiency may inflate food costs and exacerbate rural and urban food insecurity compared to a self rellance policy involving imports

some urban facts of life implications for research and policy abstract this review of recent literature explores the challenges to urban food and nutrition security in the rapidly urbanizing developing world the premise of the manuscript is that the causes of malnutrition and food insecurity in urban and rural areas are different due primarily to a number of phenomena that are unique to or exacerbated by urban living these areas include a a greater dependence on cash income b weaker informal safety nets c greater labor force participation of women and its consequences for child care d lifestyle changes particularly diet and exercise patterns e greater availability of public services but questionable access by the poor f greater exposure to environmental contamination and g governance by a new possibly nonexistent set of property rights the main focus is on identifying what is different about urban areas so as to better frame the program and policy responses

unravelling zimbabwe s food insecurity paradox implications for grain market reform in southern africa abstract the organization of zimbabwe s grain market while stimulating production and incomes in high potential smallholder areas since independence has actually contributed to food insecurity among grain deficit households in semi arid areas results of an econometric model indicate that over 100 000 tonnes of expensive commercial maize meal flow annually into rural areas while grain flows out through the state marketing channel this circuitous movement of grain a symptom of poorly functioning intrarural grain trade has effectively reduced incomes among poor rural consumers by as much as 30 the promotion of intrarural trade will require the removal of government restrictions and other critical barriers to private investment in grain trading

maize milling market reform and urban food security the case of zimbabwe abstract government policy in much of eastern and southern africa has encouraged the development of highly centralized large scale milling facilities which has in turn promoted the consumption of highly refined and expensive maize meal compared to that produced by small scale hammer mills policies to develop competitive small scale milling facilities in urban areas are apparently neglected because of the conventional perception in eastern and southern africa that urban consumers strongly prefer the refined industrially milled meals and are not responsive to price differences between various types of maize meals results of consumer and miller surveys in zimbabwe call into question the validity of these perceptions simulation analysis also indicates that the elimination of policy constraints that block small scale millers access to grain would reduce overall marketing costs thereby allowing higher producer prices lower consumer prices and or lower government subsidies the case of zimbabwe suggests that market reform may considerably reduce the magnitude of the tradeoff between governments food security and budget minimization objectives

grain marketing regulations impact on peasant production in ethiopia abstract during the past 10 years ethiopia has established an elaborate system of trade restrictions producer quotas and fixed producer prices for purchasing a substantial proportion of peasants marketable surplus recent evidence suggests that the quotas are inequitably allocated among areas and that low fixed prices reduce farmer incomes incentives to use improved inputs and grain production regulation of marketplaces and interregional grain trade have important negative effects on consumers producers and the national economy by increasing grain prices the state can stimulate production and ensure adequate supplies of grain without the need for compulsory quotas relaxing the restrictions on marketplaces and on interregional trade can benefit farmers consumers and the national economy with few costs

false promise or false premise the experience of food and input market reform in eastern and southern africa abstract the literature on the effects of agricultural market reform in africa is sharply divided and inconsistent this article attempts to reconcile opposing viewpoints on the effects of food and input market policy reform in eastern and southern africa drawing from studies of ethiopia kenya malawi zambia and zimbabwe we argue that a major source of the controversy stems from assumptions that countries have actually moved to a liberalized market environment we find that many of the most fundamental elements of the reform programs either remain unimplemented were reversed within several years or were implemented in such a way as to negate private sector investment incentives a framework is developed for explaining why some countries have been able to liberalize their food and fertilizer markets while others have not these findings have implications for how donor assistance and policy oriented research can more constructively contribute to an improved policy environment

structural adjustment and the welfare of rural smallholders a comparative analysis from sub saharan africa the direction and level of changes in real incomes brought about by structural adjustment are determined by a variety of factors including sources of income patterns of expenditures and movements in relative prices in the wake of adjustment an econometric model is used to derive an index of real income which is employed for data from cote d ivoire ghana malawi madagascar and tanzania no systematic changes in relative prices and especially in the ratio of tradable to nontradable prices were noted after the beginning of adjustment although the diversity of income sources implies that the implications of movements in relative prices on smallholder welfare are indeed complex the results indicate that there is no unequivocal pattern of increase or decline in the real welfare of the rural poor but that there are marked differences among countries and regions

government intervention in food grain markets an econometric study of tanzania abstract government intervention in food grain markets is a common feature of ldc development efforts this paper investigates the motivation for and the consequences of such intervention for the case of maize wheat and rice markets in tanzania the authors formulate and estimate an econometric model for each crop comprising four government behavioral equations in addition to domestic demand and supply equations and the social accounting identity that succeeds in explaining government interventions in both the long and short run the results suggest that the government has been following a policy of relative food grain self sufficiency that has insulated the domestic market from the international market a simulation analysis shows that this policy has had a substantial impact on food grain production and external trade

exploring environmental perspectives in lowland agriculture a q methodology study in east anglia uk abstract the role of agriculture in rural areas is changing significantly in europe with environmental protection and enhancement and provision of amenity and recreation increasingly emphasized both in public debate and in new policy initiatives faced by these shifting priorities it is increasing important to understand how farmers themselves perceive their roles in relation to environmental management in particular as recent research in new institutional economics has shown frey b s 1997 not just for the money edward elgar cheltenham policy assumptions and instruments that are at odds with the underlying motivations of agents may actually reduce achievement of policy objectives if they act to degrade beneficial norms or alter the basis on which agents make choices understanding how farmers conceive of their environmental rights and responsibilities is therefore important in helping to design agri environmental measures that can complement rather than conflict with the underlying normative assumptions that farmers themselves hold this study employs q methodology to investigate the perceptual frameworks of a sample of uk arable and mixed lowland farmers regarding the appropriate way in which to approach the environmental management of agricultural land the q analysis identifies five distinct perspectives on notions of agricultural stewardship we term these environmentalists progressives commodity conservationists jeffersonians and yeomen we discuss the main characteristics of these groups and comment on these results in the context of current uk agri environmental policy which is changing both the presumptions of farmers entitlements to agricultural payments and the expectations pertaining to farmers in relation to environmental responsibilities in conclusion we suggest that q methodology can be a valuable way of demonstrating the nature of the mental frameworks of actors in a particular context and this enables us to formulate some important questions regarding the motivations of land managers in the context of a rapidly changing rural policy

does an endogenous relationship exist between environmental and economic performance a resource based view on the horticultural sector the aim of this paper is to analyse the relationship between environmental and economic performance from the resource based theory within firms of the fresh fruit and vegetables sector this study considers that the adoption of environment friendly practices has a greater influence on firms opportunities and abilities in the agricultural sector than in manufacturing sectors and leads to closer links between performance variables the reference for this empirical analysis is a panel data of horticultural farming marketing firms in spain the voluntary environmental programmes and the heterogeneity of their application lead us to regard acquiring a competitive advantage as a relevant driver to improve environmental performance in this sector a simultaneous equations model is suggested reflecting the differential environmental effect and the assumption of endogeneity among variables the results show a positive impact of environmental differentiation on profitability and market share also suggesting that the perception of this positive experience implies greater environmental performance

nonmarket transfers and altruism abstract we examine altruistically motivated consumption transfers in an effort to account for nonmarket transfers we find that altruistic linkages lead to autonomous negotiation free transfers and that such transfers positively respond to stronger altruism we also find that given fairly natural assumptions concerning the altruism parameters mutual altruism does not necessarily result in group social harmony even though its rise narrows the conflict range in spite of enhanced transfers prompted by such a rise both parties may end up worse off these results help explain why in some social environments a shift toward market oriented transfers and exchanges may be quicker than in others as the disadvantages decline in utility associated with intragroup altruistic linkages outweigh the advantages
