fair trade and the depersonalization of ethics fair trade has changed considerably since its early days in this article we argue that these changes have led to a depersonalization of ethics thus raising serious questions about the future of fair trade in particular the depersonalization of ethics which is seen to accompany the current changes has led to greater variety in the interpretations of fair trade hiding these divergences behind the labels is increasing the risk that the movement will lose its credibility

artisanal gold and transformational exchange toward a public private partnership in tanzania abstract human rights abuses environmental predations and governance failures plague artisanal gold mining in tanzania gold s exchange value and the illegality of most artisanal gold product challenge the traditional fair trade model a potential solution additionally memories of the government s earlier failed effort to serve as a sole purchaser of artisanal gold undercut enthusiasm for statist interventions this paper presents an alternative a public private partnership ppp that would engage one or more private banks an agency within the ministry of energy and minerals and ngos or international initiatives specifically aimed at improving conditions for artisanal mine operators the concept of transformational exchange wherein a set of business transactions substantially affects societal expectations modifies behavior and promotes sustainable mechanisms frames the proposal

the management of greenhouse gas emissions and its effects on firm performance abstract climate change is a reality and the dramatic reduction of greenhouse gas ghg emissions by developed countries is a moral obligation it represents also a unique opportunity to modernize the economy and to improve the competitiveness of firms the purpose of this study is to analyze how greater consideration to the impact of their activities on the environment as well as the control and reduction of co2 emissions can improve the economic performance of firms a modern and efficient approach to the management of emissions helps to identify the activities with high energy consumption which can lead to potential savings and also to maximize image return to customers sensitive to environmental issues an econometric model that quantifies these effects is here applied to a sample of large italian firms and evidence demonstrates that the adoption of an ems environmental management system together with an appropriate control of emissions could lead to profits through an increase in demand and productivity however the improvement of productivity is weaker than the increase in demand suggesting that there is a delay between the start of the environmental efforts and the realization of economic performances

the development of a market for sustainable coffee in the netherlands rethinking the contribution of fair trade in recent years researchers have observed the process of mainstreaming fair trade and the emergence of alternative sustainability standards in the coffee industry the underlying market dynamics that have contributed to these developments are however under researched insight into these dynamics is important to understand how markets can develop to favor sustainability this study examines the major developments in the market for certified coffee in the netherlands it finds that in the creation of a market for sustainable coffee decisions that significantly influence market creation are made in the lead companies retailers and coffee roasters these decisions are made possible by the availability of multiple systems of sustainability standards and by the existence of a small segment of loyal fair trade customers that ensured that sustainability remained an issue on the coffee market in the years before the market creation took off fair trade did not become the new rule in this process but it became the benchmark against which companies could compare themselves and the basis upon which they built in adopting or developing new standards that would be more feasible in their business models

measuring the efficiency of energy intensive industries across european countries abstract this study evaluates the energy efficiency trends of five energy intensive industries in 23 european union eu countries over the period 2000 2009 in particular the performance of the construction electricity manufacturing mining and quarrying and transport sectors is examined the analysis is based on data envelopment analysis dea combined with the malmquist productivity index mpi which allows for distinctions between efficiency and technology changes over time at the second stage of the analysis cross classified multilevel modelling is applied to analyse the main drivers behind efficiency performance using a number of sector and country characteristics based on dea results an overall improvement in efficiency is observed in all sectors over the period the decomposition of the mpi indicates that technology change is primarily responsible for the improvements achieved in most sectors the results obtained by the cross classified model show among other things that the high electricity prices energy taxes and market share of the largest generator in the electricity market have a negative effect on industrial energy efficiency

time preference and international lending and borrowing in an overlapping generations model two economies represented by diamond type overlapping generations models and differing only in their pure rates of time preference are joined together capital formation balance of payments behavior and welfare are compared under autarky and openness with a positive natural rate of growth the low time preference country runs a current account surplus in the steady state but not necessarily outside it if preexisting capital is not shiftable between countries integration in the world economy makes the high time preference country worse off in the short run the ranking of stationary utility levels under autarky and openness is ambiguous

a multi criteria decision analysis model for carbon emission quota allocation in china s east coastal areas efficiency and equity abstract the allocation of carbon emission quotas is recognized as a fundamental and critical step towards the establishment of an effective nationwide carbon emissions trading cet market in china this paper aims to examine the quota allocation pertaining to china s east coastal areas these regions are pioneers in reformation and the domestic heavy emitters in this paper a multi criteria decision analysis model is proposed this model is based on the principles of efficiency and equity in order to reflect the true efficiency of carbon emissions a weighted russell direction distance model is employed three criteria namely capacity responsibility and potential are used to evaluate the degrees of equity furthermore different situations are set to evaluate the related indicators the results indicate the following 1 industrial provinces have less carbon emission quota increments 2 the yangtze river delta economic zone has notably improved energy efficiency and future quota increments correspond with the zone s current carbon emissions 3 circum bohai sea economic zone will be a major buyer of carbon emission quotas while pan pearl river delta economic zone currently receives surplus quota 4 the overall allocation of quotas converts from uneven to even as a result of gdp growth these results provide a reference for collaborative regional reductions in carbon emissions and for the construction of a cet market

heckscher ohlin revisited implications of differential population dynamics for trade within an overlapping generations framework abstract this paper investigates the implications of the addition of differential population dynamics to a simple 2 2 2 model of international trade within an overlapping generations framework the two regions considered are assumed to be identical in every respect except for the way their populations evolve over time the effects of these demographic differences are explored by comparing autarky and trade on the basis of i the analytical solutions obtained for the steady state values of key variables and ii the paths of these variables plotted using numerical results from simulation experiments carried out under two different demographic scenarios unequal population dynamics are shown to affect the relative abundance of the factors of production in each region giving rise to differentials in wage rates and rentals for capital under autarky conditions this in turn causes costs of production and relative prices to differ creating the grounds for trade in the sense of heckscher ohlin ho yet the results reveal that static ho results cannot be generalized to hold in a dynamic setting where differences in demographics cause factor proportions to evolve independently of trade over time

resource allocation based on efficiency analysis the purpose of this paper is to develop an approach to a resource allocation problem that typically appears in organizations with a centralized decision making environment for example supermarket chains banks and universities the central unit is assumed to be interested in maximizing the total amount of outputs produced by the individual units by allocating available resources to them we will develop an interactive formal approach based on data envelopment analysis dea and multiple objective linear programming molp to find the most preferred allocation plan the units are assumed to be able to modify their production in the current production possibility set within certain assumptions various assumptions are considered concerning returns to scale and the ability of each unit to modify its production plan numerical examples are used to illustrate the approach

on the political economy of means tested education vouchers abstract we use computational experiments to study the impact of means tested education vouchers on the level and distribution of educational expenditures our benchmark is a regime where public and private schools coexist our means tested voucher regime is one where households with lower incomes receive a larger voucher both the level of funding and the allocation of vouchers by income are endogenously determined by sequential majority voting we examine the effect on educational expenditures of switching from a mixed public private education regime to a means tested voucher regime or to a uniform voucher regime where all households receive the same voucher we find that i under means tested vouchers public funding for education is the smallest but average educational expenditure is the largest ii inequality of educational resources is smaller under means tested than that under uniform vouchers or the mixed regime iii the poor and the rich households prefer means testing to either the mixed or uniform regime

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

tracking the quality premium of certified coffee evidence from ethiopia summary certification of voluntary sustainability standards vss is rapidly increasing in global value chains while consumers mostly in developed countries are willing to pay significant premiums for the certification of such standards it is not well understood how effectively these incentives are transmitted to producing countries we study vss more in particular fair trade and organic certification in ethiopia s coffee sector the country s most important export commodity using a unique census of transaction data at the export level and large scale data at the production level we find that transmission of export quality premiums to coffee producers is limited with only less than one third of this premium being passed on and we find limited evidence of effects due to communal investments moreover as quality premiums are small and average production levels in these settings are low we estimate that these premiums would only lead to an increased income for coffee farmers of 22 usd per year even with a perfect transmission scenario and therefore would have little impact on the welfare of the average coffee farmer given that the vss studied are characterized by the highest premiums among vss schemes it can be assumed that even lower benefits from other vss certification schemes trickle down to producers

technical efficiency of economic systems of eu 15 countries based on energy consumption in the present study data envelopment analysis is used to determine the technical efficiency index of eu 15 countries from 1980 to 2008 using cross country comparison technical efficiency index represents the capacity of an economy to produce a higher level of gross domestic product for a given level of total energy input the level of the technical efficiency index is determined from the energy mix fossil fuels non fossil fuels nuclear energy of each country and depends on the maximization level of the production of the gross domestic product of the economic system without waste of energy resources the current study is applied in the case of the eu15 countries its scope is to highlight the differentiations of country classifications before and after the integration of nuclear energy in the energy mix of each country the main result is that the integration of nuclear energy as an additional input in the energy mixture affects negatively the technical efficiency of countries also when an economy achieves a decrease of the energy consumption produced from fossil fuels and a better exploitation of renewable energy sources clearly improves its capacity to produce more output with the given levels of inputs

the aging population and the size of the welfare state data for the united states and countries in western europe indicate a negative correlation between the dependency ratio and labor tax rates and the generosity of social transfers after other factors that influence the size of the welfare state are controlled for this occurs despite the increased political clout of the dependent population implied by the aging of the population this paper develops an overlapping generations model of intra and intergenerational transfers including old age social security and human capital formation that addresses this seeming puzzle we show that with democratic voting an increase in the dependency ratio can lead to lower taxes or less generous social transfers

should america save for its old age fiscal policy population aging and national saving he federal government has recently seen an abrupt turnaround in its budget balance from years of deficits to the now predicted years of surpluses this switch has been widely hailed since many analysts believe that the united states saves too little and that the switch to government budget surpluses can help to address that problem indeed concern about low u s saving and the long term budget outlook has increased of late as the retirement of the baby boom generation draws closer and the financial pressures associated with population aging loom larger in this paper we cite a collection of arguments for why u s fiscal policy should be used to increase national saving then we focus on whether the aging of the u s population adds force to these arguments for boosting national saving and conclude perhaps surprisingly that it may not the potential role of fiscal policy in preparing the country for the coming demographic change is at the center of recent budget proposals although the sudden emergence of budget surpluses is to a large extent based on economic and other factors beyond the government s direct control one can argue that the political will to maintain these surpluses stems in part from a desire to prepare for the retirement of the baby boomers moreover the question of whether the projected surpluses should be devoted to new spending tax cuts or debt reduction is entangled with arguments over what portion of the surpluses should go to saving social security and medicare yet the appropriate saving response to population aging is not clear cut while aging boosts the demands on future resources it also changes the rate of return the u s economy can expect from saving the net effect of aging on desired saving is

the impact of the demographic transition on capital formation the population of the united states is aging we review a variety of the implications this has for u s national saving rates and discuss the policy issues that they raise after reviewing what different models would predict for household saving over the next several decades we consider how the demographic transition may also affect national saving through changes in government behavior ways in which the composition of household saving might change as individuals age are also analyzed along with the implications of changes in government fiscal policy for asset composition excerpt

focus on fairtrade propositions for integrating fairtrade and supply chain management research driven by increased consumer interest and stakeholder pressure the number of fairtrade ft products has been steadily increasing the mainstreaming of ft means that the products are now facing stiff competition within the generic product categories in which they operate while consumers may pressure organizations for ethical conduct they are less willing to pay premium prices for fairly traded products for ft to continue to grow more efficient operating models are required to offset the premium prices paid to producers to ensure competitiveness in the market one such improvement approach may be the management of ft supply chains to investigate the feasibility of this approach this article systematically combines literature on ft with key supply chain management scm constructs and theories we discuss existing scm paradigms in the context of ft and demonstrate aspects where the efficiency of ft chains needs to be improved to ensure their viability we present propositions that demonstrate the key limitations of the ft model from the point of view of scm theory and practice and suggest the potential changes needed in the management of ft supply chains the article provides a timely first attempt to systematically combine ft with scm constructs thus establishing a basis for the further development of ft chains and for the improvement of the operating efficiency within them

earnings within education groups and overall productivity growth to offer a possible interpretation for recent empirical findings on earnings growth this paper constructs a simple model with endogenous human capital investment a distribution of natural abilities and unbiased technological progress the model predicts that in the long run average earnings within any education group will grow more slowly than average wages overall it also predicts that average earnings in high education groups ultimately will rise relative to average earnings in low education groups in the model these processes do not imply secular increases in the degree of inequality in the overall cross sectional distribution of earnings

cost based modelling of optimal emission quota allocation abstract given that a fixed national emission reduction target could be achieved by imposing emission quotas among multiple decision making units under administration a novel nonlinear programming approach is proposed in this paper to obtain an optimal emission quota allocation in a least cost way marginal emission abatement cost curves are simulated based on the environmental performance and marginal emission abatement costs measured in a set of parametric directional output distance functions with multi inputs and multi outputs further the proposed model is applied to empirically investigate the optimal carbon emission quota allocation for china s building construction industry among thirty three provinces in three different regions the results indicate that the relatively developed eastern region in china has higher marginal emission abatement cost and can be imposed with more emission quotas while the central and western regions can undertake more emission reduction approximately 74 million rmb can be saved by implementing the optimal emission allocation proposed in this paper as compared to a uniform emission quota allocation the findings are of great theoretical methodological and practical significance for policymakers and social science researchers in terms of climate change mitigation

efficient allocation of co2 emissions in china a zero sum gains data envelopment model abstract the appropriate allocation of co 2 emission quotas can build up a solid foundation for future emissions trading building co 2 emissions allocation mechanism has significant practical implications based on radial zero sum gains data envelopment zsg dea allocation model this paper uses a non radial zsg dea model to allocate co 2 emissions between different chinese provinces unlike previous studies treating co 2 as the input variable we treat co 2 as the undesirable output variable the modified model can better reflect macro production process while earlier relevant models treated co 2 emissions as inputs this paper contributes to the existing resource allocation method and allocates china s provincial co 2 emissions from the view of technical efficiency the results of our paper reveal that 1 between 2006 and 2010 the cumulative optimal amounts of co 2 emissions were higher than the actual amounts in 12 provinces and lower in other 18 provinces 2 several energy abundant provinces such as shanxi and inter mongolia need to take more responsibilities in co 2 emissions reduction 3 after the zsg dea allocation all provinces co 2 emissions are on zsg dea frontier which reflects the overall pareto optimality

the fair trade movement parameters issues and future research although fair trade has been in existence for more than 40 years discussion in the business and business ethics literature of this unique trading and campaigning movement between southern producers and northern buyers and consumers has been limited this paper seeks to redress this deficit by providing a description of the characteristics of fair trade including definitional issues market size and segmentation and the key organizations it discusses fair trade from southern producer and northern trader and consumer perspectives and highlights the key issues that currently face the fair trade movement it then identifies an initial research agenda to be followed up in subsequent papers

the intergenerational state education and pensions allocation is inefficient when generations overlap this failure can be mitigated by properly designed social arrangements we show that public financing of education and public pensions can be designed to implement an intergenerational transfer scheme supporting the complete market allocation neither the public financing of education nor the pension scheme we consider resemble standard ones in our mechanism via the public education system the young borrow from the middle aged to invest in human capital they pay back the debt via a social security tax the proceedings of which finance pension payments when the complete market allocation is achieved the rate of return implicit in this borrowinglending scheme should equal the market rate of return

corporate leadership multilevel enforcement and biodiversity regulation globalization incentives the rise of non state actors in unprecedented ways along with the creation of transnational arenas which are neither international intergovernmental nor national domestic but transborder political processes where firms non governmental organizations ngos states and social communities set up rules and provide governance mechanisms to enforce those at local level the article is anchored in the idea that public private governance matters where the primary driver is the market incentive we test the hypotheses that public private cooperation at local level is based on shared knowledge and expertise among firms civil society and state authority dealing with a natural resource which comes from the brazilian biodiversity ngos and companies have developed the ability to act as enforcers as they interpret the public international national regulation and develop an expertise through best practices that are applied to enforce biodiversity regulation at the local level through a multilevel system that operates transnationally

fair trade in france from individual innovators to contemporary networks fair trade aims at humanising the capitalist economy by serving the community instead of simply striving for financial profit the current fair trade sector is an excellent example of an innovation where networks based on ethical principles can help to effectively serve this market our analysis is based on 48 interviews amongst fair trade innovators in france and illustrates the advent of a new type of entrepreneur one that is grounded in the social and solidarity economy sse based on a service dominant logic these innovators aim to construct a new world centred on trade relationships by integrating the role of multiple player networks into the creation of value in the market

government interventions in sustainable supply chain governance experience in dutch front running cases numerous multi actor governance systems have recently emerged ensuring sustainability of international traded products business and civil society actors play a dominant role in initiating and governing sustainable supply chain governance systems sscg systems within specific product markets we see the emergence of various competing sscg systems this has led to debates on effectiveness transparency and legitimacy of these forms of self governance in the market these developments also call for a debate on appropriate roles for national governments most of the academic literature in this field focuses on methodologies for supply chain governance and their impacts but hardly addresses the roles taken on by governments and effectiveness of possible government interventions this article combines analysis of market dynamics in the timber and coffee product chains with policy analysis integrating approaches from the research fields of sustainable business and policy analysis the article shows how competition between various sustainable supply chain governance systems in the netherlands has resulted in recent market breakthroughs while initially government interventions were very limited and diverse the article suggests an approach for more systematic analysis of these dynamics and the roles of various actors by identifying both the public policy cycle and the private policy cycle

returns to education a further international update and implications this paper updates evidence on the returns to investment in education by adding estimates for new countries and refining existing estimates to bring the total number of country cases to over 60 the new cross country evidence confirms and reinforces earlier patterns namely that returns are highest for primary education the general curricula the education of women and countries with the lowest per capita income the findings have important implications for directing future investment in education which for efficiency and equity purposes should concentrate on these priority areas

the latte revolution regulation markets and consumption in the global coffee chain abstract coffee is a truly global commodity and a major foreign exchange earner in many developing countries the global coffee chain has changed dramatically as a result of deregulation new consumption patterns and evolving corporate strategies from a balanced contest between producing and consuming countries within the politics of international coffee agreements power relations shifted to the advantage of transnational corporations a relatively stable institutional environment where proportions of generated income were fairly distributed between producing and consuming countries turned into one that is more informal unstable and unequal through the lenses of global commodity chain analysis this paper examines how these transformations affect developing countries and what policy instruments are available to address the emerging imbalances

integrated weighting approach to carbon emission quotas an application case of beijing tianjin hebei region abstract the coordinated development of beijing tianjin hebei region has been included in the chinese 12th five year plan as a national strategy accordingly the cooperation of energy saving and environmental protection is an important part at the present stage establishing carbon emission trading market in china is regarded as an effective measure to reduce and control carbon dioxide emission meanwhile it is an important task for government to allocate carbon emission quotas among regions in order to explore the cross provincial carbon trading market mode of china this paper aims to construct a comprehensive index and use the integrated weighting approach to simulate the carbon quota allocation of beijing tianjin hebei region the results show that firstly the indicator of responsibility which is about 0 56 is given relatively more weight among the three indicators by comparison the weights of capacity and potential are 0 13 and 0 30 secondly the provinces with strong economic ability and lower carbon reduction potential may get fewer proportions of carbon emission quotas such as beijing thirdly since undertaking the function transfer and dispersal of beijing and tianjin hebei should have a relatively high carbon emission quotas in the future carbon trading market these results may provide insightful support for decision makers to promote collaborative carbon reduction and allocate carbon quotas in beijing tianjin hebei region of china

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

measuring macroeconomic performance in the oecd a comparison of european and non european countries abstract we study the macroeconomic performance of 19 oecd countries over the period 1970 1990 performance is defined in terms of the ability of a country s macroeconomic managers to provide four services to their citizens a high level of real gdp per capita a low rate of inflation a low rate of unemployment and a favorable trade balance we use linear programming techniques to construct a best practice macroeconomic performance frontier and to measure the performance of each country in each year relative to the frontier we then add two environmental disamenities carbon and nitrogen emissions to the service list and repeat the analysis to see if the performance rankings change throughout the analysis emphasis is placed on a comparison of the performance of 14 european oecd countries with that of five non european oecd countries we find that performance rankings do change and that the relative performance of the european countries declines when the environmental disamenities are added to the service list

fair trade organic coffee rural livelihoods and the agrarian question southern mexican coffee families in transition summary we use a random sample of coffee producing households in southern mexico to compare opportunities associated with government subsidies and migration to the role of fair trade organic coffee in household livelihoods although land and labor returns among fair trade organic coffee growers are higher than for conventional growers differences in yields are more important than price premiums moreover investment in education and labor opportunities outside coffee dominate those in fair trade organic coffee the results highlight the value of an integrated approach to the agrarian question that improves productivity and prices and supports other pathways for improving incomes

undesirable outputs in efficiency valuations abstract efficiency measurement is usually based on the assumption that inputs have to be minimized and outputs have to be maximized in a growing number of applications however undesirable outputs are incorporated into the production model which have to be minimized in this paper various approaches for treating such outputs in the framework of data envelopment analysis dea are discussed and the resulting efficient frontiers are compared new radial measures are introduced which assume that any change of the output level will involve both undesirable and desirable outputs

pareto improvement through a reallocation of carbon emission quotas abstract this article presents a methodology that discusses a reallocation of carbon emission quotas based on the zsg dea model also introduces the process of solving the zsg dea model in extensive detail and derives theorems 1 and 2 theorem 1 shows the equivalence in competition and the cooperation case while theorem 2 indicates the correlation between quota adjustment and efficiency change through this zsg dea model the determination of carbon emission quotas is no longer subjective and reasonable carbon emission quotas among countries can be obtained the reallocation of carbon emission quotas can not only ensure that all countries have 100 efficiencies but also help all countries gain through pareto improvement the conclusions of this paper are that most developed countries should increase their carbon emission quotas and that most less developed countries need to reduce theirs including the two most populous countries of china and india the reallocation process should be paid by selling the quotas of low efficient countries so that they can obtain funds to support their development while at the same time high efficient countries can produce more due to relaxation of environmental constraints thus achieving global pareto improvement

education spending in an aging america abstract in this paper we use a national panel of public school districts to study the impact of an aging population on public education spending in contrast to previous analyses that use state level data we find that the elderly have only a modest overall negative effect on education spending at the district level our results confirm however that a growing share of elderly at the state level tends to depress state spending on education these results are consistent with the hypothesis that the elderly believe only higher local spending is capitalized into house values

the effect of specialty coffee certification on household livelihood strategies and specialisation abstract farm certification is rapidly becoming a sine qua non for access to specialty coffee markets at the centre of these changes are smallholder coffee producers responsible for 80 of global coffee production although rural households are known to depend on more than agricultural production alone the literature on specialty coffee and certification has rather narrowly focused on coffee income and production in this study broader impacts are explicitly taken into account household income was decomposed into categories corresponding to specific income generating activities and coffee income was broken down into price yield and area effects results show that coffee certification encourages farmers to specialise in coffee production increasing coffee income but not total household income at least not in the short run the time and effort required to attain the higher coffee income offered by certified production means farmers have to give up other activities this substitution effect cancels out the income effect such that there is no increase in total household income the lack of an effect on total household income suggests the return to the additional labour effort required for certified coffee production is not higher than in other activities questioning the benefits of certification for small scale producers

ethical value added fair trade and the case of cafe femenino this article engages various critiques of fair trade from its participation in commodification to providing a cover for fair washing corporations and argues that fair trade has the potential to answer the challenges contained within them if and when it initiates an ongoing process of developing the ethical valued added content of the label this argument is made in a number of ways first by distinguishing between economic and human development impacts and ethics this article argues that these impacts are necessary but not sufficient conditions for ethical trade second it engages the question of the possibility of ethical practice in economics generally developing the idea that when economics is concerned with securing the material basis of a broad range of life capacities it becomes ethical third fair trade practice itself is examined from this standpoint and is conceived of as both comprising a promising ethical value added practice as well as posing a problem in its current formulation that the framework of ethical value added can help understand and resolve finally an examination of these theoretical ideas in practice is undertaken through a case study of cafe femenino a fair trade coffee produced in peru in conclusion it is argued that for fair trade to build upon its economic and human impacts and therefore remain a meaningful ethical and economic alternative to corporate capitalism and globalization it must distinguish itself clearly in ethics from those market relations it wishes explicitly or implicitly to challenge

do corporate global environmental standards create or destroy market value arguments can be made on both sides of the question of whether a stringent global corporate environmental standard represents a competitive asset or liability for multinational enterprises mnes investing in emerging and developing markets analyzing the global environmental standards of a sample of u s based mnes in relation to their stock market performance we find that firms adopting a single stringent global environmental standard have much higher market values as measured by tobin sq than firms defaulting to less stringent or poorly enforced host country standards thus developing countries that use lax environmental regulations to attract foreign direct investment may end up attracting poorer quality and perhaps less competitive firms our results also suggest that externalities are incorporated to a significant extent in firm valuation we discuss plausible reasons for this observation

an exploration of opportunities for the growth of the fair trade market three cases of craft organisations businesses that maintain ethical standards have an advantage in the marketplace based on the increasing interest of consumers in products that have a social and ethical component fair trade organisations that adopt environmental social and ethical principles in trading are in a good position to make the most of this growing interest in the market however it is unclear whether fair trade organisations are taking full advantage of emerging market opportunities for ethically traded products this research explores this issue by describing the business strategies of three fair trade organisations that import and sell craft goods into western countries and evaluates them in the context of this growing market the research findings indicate that in order to remain in business fair trade craft organisations have had to adopt better business practices in recent years improving quality customer service and product offerings to customers however growth appears to be limited as distribution remains focused on a small niche market this paper explores the distribution strategies of two fair trade commodity organisations that are successfully reaching a wider customer base demonstrating that fair trade products have a unique selling advantage in the mainstream marketplace in conclusion fair trade craft organisations are not exploiting this market opportunity to the degree they should and will need to explore wider distribution and alternative business strategies to expand their market share

the co operative and the corporation competing visions of the future of fair trade this paper provides an analysis of the fair trade network in the north through a comparative assessment of two distinctly different fair trade certified roasters planet bean a worker owned co operative in guelph ontario and starbucks coffee company the world s largest specialty roaster the two organizations are assessed on the basis of their distinct visions of the fair trade mission and their understandings of consumer sovereignty it is concluded that the objectives of planet bean are more compatible with the moral mission of fair trade even while the network has become increasingly dependent on the market reach of corporations like starbucks raising difficult prospects for the future of fair trade

effects of fair trade certification on social capital the case of rwandan coffee producers summary fair trade certification may have important social effects on small scale producers but empirical evidence is limited we conducted logistic regressions using data from a 2009 survey of rwandan coffee farmers to estimate the link between fair trade and social capital measured as farmer trust and participation while controlling for various other factors that could influence social capital particularly membership in a cooperative organization the results show a negative association between fair trade and farmer trust in cooperative leadership and a positive association with a perceived higher level of participation of women social capital is linked most significantly to farmers interaction with their neighbors

how can china reach its co2 intensity reduction targets by 2020 a regional allocation based on equity and development in late 2009 the chinese government committed to cut its carbon dioxide emissions per unit of gross domestic product gdp by 40 to 45 of 2005 levels by 2020 this has raised the issue of how to allocate the co2 reduction target regionally to meet the national reduction target to meet this objective the following aspects may be taken into consideration equity principles common but differentiated responsibilities intensity reduction target fulfillment and economic difference and reduction potential among provinces this paper selects per capita gdp accumulated fossil fuel related co2 emissions and energy consumption per unit of industrial added value as indicators for emission reduction capacity responsibility and potential respectively based on these three indicators a comprehensive index is developed and an intensity allocation model constructed as decision makers may have different preferences when allocating the reduction burden we allocate different weights to the indicators analyzing the results using cluster analysis the following aspects may also be considered together with the national regional development strategy to determine how to share the burden the reduction potential of various regions implementation potential of the plans and promotion of a highly efficient low carbon economic development model

regional allocation of co2 emissions allowance over provinces in china by 2020 the mitigation efforts of china are increasingly important for meeting global climate target since the rapid economic growth of china has led to an increasing share in the world s total co2 emissions this paper sets out to explore the approach for realizing china s national mitigation targets submitted to the unfccc as part of the copenhagen accord that is to reduce the intensity of co2 emissions per unit of gdp by 40 45 by 2020 as well as reducing the energy intensity and increasing the share of non fossil fuel consumption through regional allocation of emission allowance over china s provinces since the realization of china s mitigation target essentially represents a total amount emission allowance allocation problem an improved zero sum gains data envelopment analysis optimization model which could deal with the constant total amount resources allocation is proposed in this study by utilizing this model and based on several scenarios of china s economic growth co2 emissions and energy consumption a new efficient emission allowance allocation scheme on provincial level for china by 2020 is proposed the allocation results indicate that different provinces have to shoulder different mitigation burdens in terms of emission intensity reduction energy intensity reduction and share of non fossil fuels increase

governance and trade in fresh vegetables the impact of uk supermarkets on the african horticulture industry production of fresh vegetables for export has grown rapidly in a number of countries in sub saharan africa over the last decade this trade brings producers and exporters based in africa together with importers and retailers in europe large retailers in europe play a decisive role in structuring the production and processing of fresh vegetables exported from africa the requirements they specify for cost quality delivery product variety innovation food safety and quality systems help top determine what types of producers and processors are able to gain access to the fresh vegetables chain and the activities they must carry out the control over the fresh vegetables trade exercised by uk supermarkets has clear consequences for inclusion and exclusion of producers and exporters of differing types and for the long term prospects for the fresh vegetables industry in the two major exporting countries studied kenya and zimbabwe

fair trade three key challenges for reaching the mainstream after nearly 20 years of work by activists fair trade a movement establishing alternative trading organizations to ensure minimal returns safe working conditions and environmentally sustainable production is now gaining steam with increasing awareness and availability across a variety of products however this article addresses several major remaining challenges a a lack of agreement about what fair trade really means and how it should be certified b uneven awareness and availability across different areas with marked differences between some parts of europe and north america that reflect more fundamental debates about distribution c larger questions about the extent of the potential contribution of fair trade to development under the current system including limitations on the number and types of workers affected and the fair trade focus on commodity goods

econometric estimation of technical and environmental efficiency an application to dutch dairy farms in this article we estimate the technical and environmental efficiency of a panel of dutch dairy farms nitrogen surplus arising from the application of excessive amounts of manure and chemical fertilizer is treated as an environmentally detrimental input a stochastic translog production frontier is specified to estimate the output oriented technical efficiency environmental efficiency is estimated as the input oriented technical efficiency of a single input the nitrogen surplus of each farm the mean output oriented technical efficiency is rather high 0 894 but the mean input oriented environmental efficiency is only 0 441 intensive dairy farms are both technically and environmentally more efficient than extensive farms

education social security and growth abstract we study the role of government s allocation of tax revenues between two outlays public investment in education a transfer to the young generation and social security benefits to the older generation in an overlapping generations economy with pay as you go social security and altruistically motivated transfers from parents to children we analyze how the allocation of the tax revenues between the two outlays affects growth and welfare in competitive equilibria a we obtain comparative dynamics results for nonstationary equilibria subject to a change in the allocation profile b for stationary equilibria we show that for a given allocation profile of the tax revenues educational subsidies can either increase the growth rate or decrease it depending on the parameters of the model preferences production function and the tax rate c if government seeks to allocate funds in a way that maximizes the growth rate we demonstrate that under some plausible conditions it is not optimal to maintain pay as you go social security however if parents preferences combine strong concern for their retirement with significant degree of altruism towards their children then pay as you go social security system does enhance growth and welfare

strategic voting in agenda controlled committee experiments this paper reports results of committee voting experiments with a fixed agenda that specified a sequence of binary decisions in this particular context the agenda setter can control the ultimate committee decision if it is known whether voting behavior is myopic or strategic subjects initially voted in accordance with myopic voting rules strategic behavior was more prevalent with experience the use of the same induced preferences in successive meetings was more likely to induce strategic voting than the provision of public information concerning the numbers of voters of each preference type copyright 1989 by american economic association

allocating fixed costs and resources via data envelopment analysis abstract in this paper we show that data envelopment analysis dea can be viewed as maximising the average efficiency of the decision making units dmus in an organisation building upon this we present dea based models for a allocating fixed costs to dmus and b allocating input resources to dmus simultaneous to allocating input resources output targets are also decided for each dmu numeric results are presented for a number of example problems taken from the literature

allocation of carbon dioxide emission permits with the minimum cost for chinese provinces in big data environment abstract the environmental problem and global warming have drawn many governments attention in order to solve the problem reasonable allocation of carbon dioxide emission cde permits is an important issue because it sets the targets for the decision making units to control the amount of carbon dioxide emission in this paper a new data envelopment analysis approach is proposed to evaluate the efficiency of decision making units in a big data environment and set the carbon dioxide emission permits for each decision making unit with the minimum costs comparing with the previous works on carbon dioxide emission permits allocation we firstly allocate the amount of carbon dioxide emission permits taking account into the cost each decision making unit should take to achieve its target moreover two kinds of linear programming problems are developed under efficiency invariance principle and efficiency changeability principle respectively as the allocation of carbon dioxide emission permits causes the minimum cost the decision making units are more easily to accept the allocation alternative finally our approach is applied to the carbon dioxide emission permits allocation among chinese provinces the results show that the approach can well allocate the cde permits with the minimum cost and also reveal the relationship between the marginal cost of reducing cde permits and the adjustment on them

a generalized dea model for centralized resource allocation abstract in this paper we introduced a new generalized centralized resource allocation model which extends lozano and villa s and asmild et al s models to a more general case in order to uncover the sources of such total input contraction in the generalized centralized resource allocation model we applied the structural efficiency to further decompose it into three components the aggregate technical efficiency the aggregate allocative efficiency and re transferable efficiency components the proposed models are not only flexible enough for the central decision maker to adjust the inputs and outputs to achieve the total input contraction but also identify the sources of such total input contraction thereby giving rise to an important interpretation and understanding of the generalized centralized resource allocation model finally an empirical example is used to illustrate the approach

what do corporations have to do with fair trade positive and normative analysis from a value chain perspective there has been tremendous growth in the sales of certified fair trade products since the introduction of the first of these goods in the netherlands in 1988 many would argue that this rapid growth has been due in large part to the increasing involvement of corporations still participation by corporations in fair trade has not been welcomed by all the basic point of contention is that while corporate participation has the potential to rapidly extend the market for fair trade goods it threatens key aspects of what many see as the original vision of fair trade most notably a primary concern for the plight of small producers and the goal of developing an alternative approach to trade and development and may even be undermining its long term survival the primary purpose of this article is to explore the normative issues involved in corporate participation in fair trade in order to do that however it first provides a positive analysis of how corporations are actually involved in fair trade in order to achieve both of these ends the article draws upon global value chain analysis

a new frontier approach to model the eco efficiency in european countries abstract this study aims to evaluate the resource and environment efficiency problem of european countries we specify a new stochastic frontier model where gross domestic product gdp is considered as the desirable output and greenhouse gases ghg emissions as the undesirable output capital labor fossil fuels and renewable energy consumption are regarded as inputs gdp ghg ratio is maximized given the values of the other four variables the study is divided into two distinct periods 2000 2004 and 2005 2011 this division is related to the implementation of the kyoto protocol in 2005 and will allow us to evaluate the difference between the levels of efficiency before and after the establishment of environmental targets since stochastic frontier models are typically ill posed a new maximum entropy approach to assess technical efficiency which combines information from the data envelopment analysis and the structure of composed error from the stochastic frontier approach without requiring distributional assumptions is presented in this work

olympic ranking based on a zero sum gains dea model abstract it is usual to rank the participant countries in the olympic games in accordance with the number of medals they have won an alternative ranking is suggested in this paper this ranking is based on each country s ability to win medals in relation to its available resources this is an efficiency that can be measured with the help of data envelopment analysis dea for which two models exist the traditional dea model that takes into account variable returns to scale and a dea model based on the premise that the sum of the gains is zero constant sum of outputs it is the latter that is developed in this paper

assessment of the environmental efficiency of the electricity mix of the top european economies via data envelopment analysis abstract moving towards a more sustainable energy system is a major goal of modern societies that aim to minimize the dependence on fossil fuels and the associated anthropogenic impacts in this article the combined use of life cycle assessment lca and data envelopment analysis dea is applied to analyse the environmental performance eco efficiency of the electricity mix of the top european economies this approach allows identifying environmentally efficient and inefficient countries considering as undesirable inputs several environmental impacts associated with the production of 1 kwh regarded as output the method provides as well targets for the inefficient countries that if attained would make them efficient our results provide valuable insight for governments and policy makers that aim to satisfy the electricity demand while minimizing the associated environmental impact

is the lithuanian economy approaching the goals of sustainable energy and climate change mitigation evidence from dea based environmental performance index abstract even though lithuania has seen extensive social and political transformations there is still a gap in the literature on environmental performance of lithuanian economy specifically the environmental pressures stemming from economic activities have never been analysed in lines with the principles of production economics this paper therefore aims to estimate the environmental performance index epi for lithuanian economic sectors the paper presents the underlying trends in greenhouse gas emissions in lithuania the environmental performance index is estimated by employing the data envelopment analysis in the spirit of the hicks moorsteen indices the present analysis is based on the data from the world input output database specifically the environmental technology is defined in terms of the value added carbon and nitrous oxide emissions labour capital and energy results of the analysis imply that the analysed economic sectors can be grouped into the four clusters with respect to the mean epi and its rate of growth pulp paper and agricultural sectors fall into the best performing group featuring the highest mean epi and the highest growth rate petroleum production and air transport sectors are those featuring the lowest environmental performance therefore the latter sectors should be given an especial importance when developing strategies for increase in sustainability

mainstreaming fair trade coffee from partnership to traceability summary this article analyzes the recent growth of fair trade and the mainstreaming of this previously alternative arena focusing on coffee i identify a continuum of buyers ranging from mission driven enterprises that uphold alternative ideas and practices based on social ecological and place based commitments to quality driven firms that selectively foster fair trade conventions to ensure reliable supplies of excellent coffee to market driven corporations that largely pursue commercial industrial conventions rooted in price competition and product regulation using a commodity network approach my analysis illuminates the impacts of diverse buyer relations on producer groups and how relations are in some cases shifting from partnership to traceability

endogenous fiscal policy and capital market transmissions in the presence of demographic shocks abstract previous analyses of population aging mainly focused on the social security implications of the aging trend this paper addresses aging in an open economy framework with two regions that have politically responsive fiscal policy regarding education finance demographic shocks start an economic growth process but results are sensitive to a critical parameter in the model that indicates return to education spending low values of this parameter are associated with less favorable economic outcomes hence a policy implication emerges that enhancing the education system might pay off in terms of easing the negative growth and welfare consequences of expected demographic shocks

ethical objections to fairtrade the fairtrade movement is a group of businesses claiming to trade ethically the claims are evaluated under a range of criteria derived from the utilitarian ethic firstly if aid or charity money is diverted from the very poorest people to the quite poor or the rich there is an increase in death and destitution it is shown that little of the extra paid by consumers for fairtrade reaches farmers sometimes none it cannot be shown that it has a positive impact on fairtrade farmers in general but evidence suggesting it harms others is presented many of the weaknesses are due to an attempt to impose political views on farmers and others secondly the unfair trading criteria require that sellers do not lie about their product nor withhold information that might alter the decisions of a substantial proportion of buyers it is argued that the system only can exist because of the failure of the fairtrade industry to give the facts on what happens to the money and what it can be proved it achieves this unfair trading compromises the reputation of charities in general much of the trading may constitute the criminal offence of unfair trading in the eu

the institutionalization of fair trade more than just a degraded form of social action the context of economic globalization has contributed to the emergence of a new form of social action which has spread into the economic sphere in the form of the new social economic movements the emblematic figure of this new generation of social movements is fair trade which influences the economy towards political or social ends having emerged from multiple alternative trade practices fair trade has gradually become institutionalized since the professionalization of world shops the arrival of fair trade products in the food industry and the establishment of an official fair trade label with the strength that this institutionalization has generated fair trade can now be considered a real trade system that questions as much as it renews the traditional economic system in parallel this transformation has exacerbated the tensions within the movement which can be characterized as a clash between a radical militant pole and a softer more commercial one however it is not the actual institutionalization of fair trade which is being debated among fair trade actors on either side of the fence but rather the challenges inherent in finding an economic institutionalization acceptable to social economic movements therefore the institutionalization process of fair trade should not be seen as mere degradation of social action but rather as typical of the institutionalization process of new social economic movements if we need to worry about the highjacking and alteration of the fair trade movement by the dominant economic system the opposite is no less likely as new social economic movements contribute to an ethical restructuring of markets

engel curves for fair trade consumption and development perspectives for producers evidence from data on real fairtrade purchases while fairtrade sales have exhibited two digit growth rates over recent decades their capacity to become large enough to generate substantial gains for producers is still uncertain estimating fai

aging transitional dynamics and gains from trade abstract we formulate a two country two good two factor two period lived overlapping generations model to examine how population aging determines the pattern of and gains from trade two main results are obtained first the aging country endogenously becomes a small country exporting the capital intensive good whereas the younger country endogenously dominates the world economy determining the world prices in the free trade steady state second although uncompensated free trade cannot be pareto superior to autarky there exists a compensation scheme applied within each country such that free trade is pareto superior to autarky

aging pension reform and capital flows a multi country simulation model we present a quantitative analysis of the effects of population aging and pension reform on international capital markets first demographic change alters the time path of aggregate savings within each country second this process may be amplified when a pension reform shifts old age provision towards more pre funding third while the patterns of population aging are similar in most countries timing and initial conditions differ substantially hence to the extent that capital is internationally mobile population aging will induce capital flows between countries all three effects influence the rate of return to capital and interact with the demand for capital in production and with labor supply in order to quantify these effects we develop a computational general equilibrium model we feed this multi country overlapping generations model with detailed long term demographic projections for seven world regions our simulations indicate that capital flows from fast aging regions to the rest of the world will initially be substantial but that trends are reversed when households decumulate savings we also conclude that closed economy models of pension reform miss quantitatively important effects of international capital mobility this version 25 august 2004

are fair trade goods credence goods a new proposal with french illustrations in the literature fair trade ft goods are usually associated with other products differentiated by process attributes such as organic food genetically modified gm food or child labour free clothing all of these products are regarded as credence goods this classification refers to the simplified definition of credence goods which describes product attributes which consumers cannot evaluate even after having consumed the good focusing on the characteristics of ft goods this article proposes a reassessment of the link between ft goods and credence properties as defined by darby and karni we first demonstrate that 1 the usual classification masks important particularities of ft goods compared to other goods with process attributes and 2 the full definition of credence goods may even provide a better description of the quality of ft goods however and this is our second theoretical contribution the lack of consensus among experts concerning ft standards and their level of efficiency encourage us to consider ft goods as indeterminate goods as defined by lupton this result leads us to suggest a new typology of product attributes summarized in an innovative diagram it sheds light on how competition between the different ft approaches works and why the ft market is still confined to a niche if not threatened with collapse we mainly illustrate our theoretical analysis with observations relating to the french ft market and institutions

a gendered value chain approach to codes of conduct in african horticulture codes of conduct covering the employment conditions of southern producers exporting to european markets mushroomed throughout the 1990s especially in the horticulture sector linking uk and european supermarkets with export firms in africa the majority of employment in this sector is informal a significant proportion of which is female this paper explores the gender sensitivity of codes currently applied in the african export horticulture sector from an analytical perspective that combines global value chain and gendered economy approaches through an analysis of these two approaches it develops a gender pyramid which provides a framework for mapping and assessing the gender content of codes of conduct the pyramid is applied to codes that cover employment conditions in three commodity groups and countries exporting to european markets south african fruit kenyan flowers and zambian vegetables and flowers it concludes that the gender sensitivity of codes needs to be greatly enhanced if they are to adequately address employment conditions relevant to informal and especially women workers

aging population and education finance abstract conventional wisdom suggests that aging of population will increase political pressure to tilt the composition of social spending in favor of the elderly while potentially sacrificing other publicly provided goods such as education this view seems to be supported by recent empirical findings that per child public education spending tends to be lower in us jurisdictions with higher fraction of elderly residents do these cross sectional findings also carry the dynamic implication that longevity will lead over time to waning political support for funding of public education this paper challenges such implication we present a model that is consistent with the aforementioned cross sectional regressions yet predicts an overall positive impact of increasing longevity on public education funding and economic growth

efficiency and allocation of emission allowances and energy consumption over more sustainable european economies abstract efficient use of energy reduction in fossil fuel dependence and control of co2 emissions are all fundamental to development of a sustainable economy competitiveness in energy use saves imports of oil and gas increases gross domestic product and creates new jobs in the renewable energy and energy efficiency sectors this study identifies the more or less competitive european union member states in terms of sustainable growth using data envelopment analysis dea model and proposes new allocations of country greenhouse gas limits and energy consumption using a zero sum gains dea model the analysis of european countries fills a gap in the existing literature and contributes to the discussion on the 2020 2030 european strategy proposing an efficiency based indicator which measures country performance in terms of economic social and environmental factors gdp represents the economic factor population represents the social factor and emissions final and renewable energy consumption are the environmental factors the numerical results show that the initial allocations are inefficient applying the modelled reallocation the most efficient countries are rewarded by potential increases in emission and energy consumption while the least efficient countries must bring about decreases to achieve full efficiency

mapping research topics and theories in private regulation for sustainability in global value chains the globalization of production and trade has contributed to the rise in complex global value chains where the reach of state regulation is limited as an alternative private regulation developed and administered by companies industry associations and nongovernmental organizations has emerged to safeguard economic environmental and social sustainability in producer countries and along the value chain the academic literature on private regulation in global value chains has grown over the last decade but currently few major reviews of the research have been undertaken this paper examines peer reviewed research in the relevant disciplines published in academic journals up to december 2011 our goal is to identify and classify the topics and theories in the global value chain literature we conclude that the number of articles explicitly examining private regulation in a global value chain context is relatively small when considering the importance and growth of these chains in the world s economy we also conclude that agriculture forestry and apparel manufacturing are the most often studied economic sectors in contrast other sectors such as the information communication and technology with their complex global value chains and often problematic environmental and social conditions are understudied

a dea approach for estimating the agricultural energy and environmental efficiency of eu countries this study attempts to evaluate the energy and environmental efficiency of the primary sectors of the eu member state countries the evaluation is based on a non radial data envelopment analysis dea model which allows for non proportional adjustments to energy inputs and undesirable outputs and thus it provides different estimations for energy and environmental efficiency scores the 2001 2008 time period was selected for this research one of the most important findings is that countries like germany sweden or austria with strong environmental protection standards appear to be less energy and environmentally efficient compared with countries like denmark belgium spain france or ireland in addition a series of eastern european countries achieve low efficiency scores which can be characterized as expectable due to low technology level being implemented in the primary production process there are also two sub periods for this research the first one 2001 2006 covers the fully coupled with specific cultivations period for subsidy administation and the second 2007 2008 where the new decoupled subsidy scheme was implemented there are significant hints for considerable changes of energy and environmental efficiency after the implementation of the the new cap with the new member states siginificantly differ of both energy and environmental efficiency copmared with the older ones

institutional emergence in an era of globalization the rise of transnational private regulation of labor and environmental conditions1 why have systems of transnational private regulation recently emerged to certify corporate social and environmental performance different conceptions of institutional emergence underlie different answers to this question many scholars argue that firms create certification systems to solve problems in the market a view rooted in a conception of institutions as solutions to collective action problems the author develops a different account by viewing institutions as the outcome of political contestation and by analyzing conflict and institutional entrepreneurship among a wide array of actors using a comparative case study design the analysis shows how these arguments explain the formation of social and environmental certification associations both theoretical approaches are needed but strong versions of the market based approach overlook an important set of dynamics that the author calls the political construction of market institutions the analysis shows how both problem solving in markets and

standards as a new form of social contract sustainability initiatives in the coffee industry abstract in the former age of national capitalism the achievement of market fairness was embedded in a normative framework generated by government labor unions and perhaps religious authority in the current age of global capitalism new actors such as ngos industry associations and public private partnerships provide the normative framework that corporations use for social legitimacy in this context standard setting processes operate as new forms of social contract where the state rather than being directly involved between the parties provides a form of basic guarantee while more or less accountable ngos and firms are in charge of hammering out the bargains this article examines the dynamics of this new configuration through the case study of sustainability initiatives in the coffee sector it addresses four questions 1 are these standards effective in communicating information and creating new markets 2 to what extent do they embed elements of collective and private interests 3 is sustainability content actually delivered to their intended beneficiaries and 4 what is the role of public policy in addressing their shortcomings

a study of allocative efficiency of pm2 5 emission rights based on a zero sum gains data envelopment model abstract it is an urgent task for china to control haze emission in environmental treatment emission right trading is a feasible way to achieve the reduction of pollutant emission on the premise that the total pollutant emission amount is under control and the allocation of initial emission rights based on the target total amount is the key to emission right trading in this paper via the input oriented zsg dea model the inter provincial allocative efficiency of pm2 5 emission rights is investigated under the condition that the target total amount is fixed the results showed that 1 after initial emission rights were allocated in accordance with the zsg dea model pm2 5 emission amounts of all provinces would be in a new common dea frontier so as to realize the overall pareto optimality with a set total amount 2 two factors namely land areas and atmospheric environmental capacities of all provinces were considered in the actual allocation to avoid the homogenization of all evaluated units found in the previous evaluation literature on allocative efficiency thereby making the evaluation results more in line with the actual situations in all provinces such an investigation approach can provide guidance on the allocation of initial emission rights in emission right trading and the research results can offer empirical support for haze reducing work load conducted by central and local governments of china

faith and fair trade the moderating role of contextual religious salience normative and historical arguments support the idea that religion potentially shapes decisions to support fair trade products that said the question of how religion influences organizational decision makers to purchase fair trade products in a business to business context has remained largely unaddressed this research examines the interactive effect of individual religious commitment and contextual religious salience on an individual s willingness to pay a price premium for a fair trade product when buying on behalf of an organization findings from two experimental studies involving 75 and 87 working individuals respectively reveal that the effect of a decision maker s religious commitment on his or her willingness to pay a price premium for the purchase of a fair trade product on behalf of an organization is moderated by the contextual salience of religion specifically when religion is highly salient in the organizational context religious commitment is positively related to the decision maker s willingness to pay a premium for the fair trade product when contextual religious salience is low religious commitment and willingness to pay a premium are unrelated implications for theory and practice are presented

a more scientific allocation scheme of carbon dioxide emissions allowances the case from china abstract efficient allocation of carbon dioxide co2 emissions allowances is essential to the realization of the emissions reduction goal using china as an example this study applies a zero sum gains data envelopment analysis zsg dea model to translate the country s reduction target into provincial goals based on the chinese government s 2020 reduction goal to evaluate efficiency scores we employ the epsilon based measure model that combines radial and non radial characteristics different from prior studies we emphasize the effect of industrial structure on co2 emissions and calculate a composite gross domestic product gdp index as one of the output variables by utilizing the zsg dea model and based on china s provincial co2 emissions allowances as the input variable the composite gdp index and the population as the output variable we obtain an optimal reallocation scheme after four iterations a comparison between the results and official reduction goals shows that the government should increase co2 emissions allowances appropriately for most provinces with high proportions more than 40 of second industry increment in gdp thereby carrying implications for policymakers with china as an example these findings have global implications as regards developing a more scientific allocation scheme especially for regions with unbalanced industrial structures
