landlords tenants and technological innovations abstract there is a long standing belief that landlords and capitalists have used their control over the means of production to direct the development and adoption of technologies which have increased their welfare at the expense of workers there is also a wide spread belief that the interlinkage between credit and tenancy markets which seems so prevalent in ldcs provides further impetus to the resistance of innovations innovations which make tenants better off reduce their demand for loans and thus make landlords qua creditors worse off these contentions have typically been dismissed out of hand by standard welfare economics arguments the rural environment of most ldcs may not however be adequately described by the standard economic model on which this welfare analysis is based in particular in many ldcs sharecropping contracts are widely employed there is evidence of widespread unemployment and there is not the full set of risk and capital markets required by the competitive paradigm the objective of this paper is to show under quite general conditions that the institutional structure of the economy may indeed be an important determinant of whether a particular innovation will or will not be adopted we show that 1 i landlords may wish to and can resist innovations which unambiguously increase production whenever sharecropping contracts are employed 2 ii conversely landlords may adopt innovations which not only lower the welfare of workers but even lower net national product 3 iii the presence of interlinkage may indeed affect the adoption of a new technology however the reason for this is only partly related to the effect of innovations on tenants borrowing indeed we show that innovations may increase as well as decrease the tenants demand for borrowing

material flows vs natural capital what makes an economy sustainable abstract in the discourse about sustainable development constant natural capital is frequently referred to as a criterion for ecological sustainability but what is natural capital the concept will be analyzed by presenting arguments in favour of using the term and different versions of sustainability strong and weak subsequently a critique of the natural capital concept is brought forward from an ecological as well as from an economic perspective following this critique the use of material inputs and the material input per unit of service mips as a measure for the environmental impact potential is suggested dematerialisation is understood to be an alternative management rule for sustainability in conclusion a change of perspective is proposed due to the conceptual and measurement problems associated with the constant natural capital criterion which refers to a stock it seems more reasonable from a scientific as well as from a practical perspective to add flows i e material inputs to a decision criterion for whether a development is sustainable or not

interlinked contracts and moral hazard in investment abstract in agricultural tenancy arrangements the tenant is often required to undertake effort aimed at maintaining and improving the productive stocks this paper investigate the design of contracts which induce optimal investment of such effort it is found that a long term contract which interlinks tenancy with a credit agreement is optimal in equilibrium the tenant obtains credit from the landlord at a rate of interest below the market and is perpetually indebted to the landlord

stability of zero growth economics analysed with a minskyan model abstract as humanity is becoming increasingly confronted by earth s finite biophysical limits there is increasing interest in questions about the stability and equitability of a zero growth capitalist economy most notably if one maintains a positive interest rate for loans can a zero growth economy be stable this question has been explored on a few different macroeconomic models and both yes and no answers have been obtained however economies can become unstable whether or not there is ongoing underlying growth in productivity with which to sustain growth in output here we attempt for the first time to assess via a model the relative stability of growth versus no growth scenarios the model employed draws from keen s model of the minsky financial instability hypothesis the analysis focuses on dynamics as opposed to equilibrium and scenarios of growth and no growth of output gdp are obtained by tweaking a productivity growth input parameter we confirm that with or without growth there can be both stable and unstable scenarios to maintain stability firms must not change their debt levels or target debt levels too quickly further according to the model the wages share is higher for zero growth scenarios although there are more frequent substantial drops in employment

the role of consumption credit in agricultural tenancy abstract in traditional agriculture it is common practice for landlords to give consumption loans to their own tenants if the tenant derives all his income from the landlord it is puzzling that the landlors needs another means of expropriating the surplus he could just raise the rent the paper suggests that consumption credit may be a side payment designed to enable the landlord to absorb the tenant s risk due to weather uncertainty without weakening his incentive to work tenancy is modelled as an agency contract designed in terms of information may be available to the landlord

capitalism s growth imperative a capitalist firm operating in a competitive market is subject to a growth imperative because uncertainty about the profit rate under a no growth policy makes the firm s prospects highly unattractive in finite time and bankruptcy practically certain in the long run a no growth policy determines consumption and investment so that they and capital would remain constant over time if the latter s expected return were realized with certainty simulation is used to arrive at the probability of bankruptcy by the end of t periods and the expected values of capital and money for relevant combinations of time and uncertainty under successively more realistic models of a no growth firm in a competitive market the sensitivity of the results to variation in the parameters in each of the models is evaluated finally we consider what firms might actually do to achieve the benefits of growth and more attractive prospects of survival

cost sharing arrangements under sharecropping moral hazard incentive flexibility and risk this paper explains the rationale and describes the characteristics of cost sharing arrangements in rural developing economies focusing on the risk and incentive properties of alternative cost contracts and on their flexibility their ability to adapt to environmental changes it is shown that where labor inputs are difficult to monitor the rule that cost shares and output shares be equalized will not hold and is not constrained pareto efficient and that cost sharing contracts have a decided advantage over contracts which specify the level of inputs whenever there are asymmetries of information regarding production technology between the landlord and the tenant

agriculture in recent development theory abstract this paper is a critical review of recent contributions to the literature on agriculture in development theory it considers and compares the main lines of advance made within neoclassical neo marxian and structuralist approaches recent neo marxian and structuralist studies of agrarian development reveal that traditional agriculture is neither stationary nor efficient that resource allocation cannot be separated from wealth distribution or production organization that forms of surplus appropriation do not necessarily follow the dictates of efficiency that the social relations of production may inhibit accumulation and determine the forms of technological change that the state s role in primitive accumulation is more economic than explicitly coercive political and that political and macroeconomic constraints preclude a simple get the prices right view of the intersectoral terms of trade the thrust of these developments is to challenge both neoclassical and some orthodox marxian formulations of agrarian development issues and add to the insights to be gleaned from a political economy of development

the employment effects of sustainable development policies abstract this paper argues that it is time for ecological economists to bring the employment impacts of sustainable development policies to the forefront of the research agenda important conservation efforts continue to founder because of their perceived employment effects the paper examines the evidence on the employment impacts of sustainable development policies and argues that maintaining or even increasing employment depends critically on appropriate policy design and attention to the political economy of implementation of policies the paper concludes that a better understanding of these issues fair labour market and structural adjustment programs and especially forward planning to anticipate problem areas must replace the piecemeal knee jerk reactions to environmental issues such as were evident in australia during the last federal election

a theory of interlinked rural transactions this paper argues that the interlinking of labor output and credit contracts often observed in rural economies can be regarded as an attempt to improve allocative efficiency in the face of moral hazard it advances an economic explanation of the phenomenon which is rooted in the view that prevalent modes of transaction of which interlinked contracts are an example are shaped by technological considerations interlinking is shown to be an efficient economic response to unequally distributed information arising from the uncertainty which characterizes subsistence agriculture all pareto efficient allocations require a combination of wage cum output sharing with consumption credit contracts the analytical framework set up to demonstrate the results is used to examine the response of the contractual parameters to changes in i the returns to alternative occupations available to tenant laborers ii the cost of credit to the village economy and iii the riskiness of cultivation the analysis concludes that public policy to alleviate rural poverty must recognize the relationships between technological considerations and modes of transaction in the absence of a complete set of markets

debt deleveraging and the liquidity trap a fisher minsky koo approach in this paper we present a simple new keynesian style model of debt driven slumps that is situations in which an overhang of debt on the part of some agents who are forced into rapid deleveraging is depressing aggregate demand making some agents debt constrained is a surprisingly powerful assumption fisherian debt deflation the possibility of a liquidity trap the paradox of thrift a keynesiantype multiplier and a rationale for expansionary fiscal policy all emerge naturally from the model we argue that this approach sheds considerable light both on current economic difficulties and on historical episodes including japan s lost decade now in its 18th year and the great depression itself

ecological macroeconomic models assessing current developments our society faces a dilemma while continued economic growth is ecologically unsustainable low or negative rates of economic growth are accompanied by adverse social impacts hence there is a need for macroeconomic tools that can help identify socially sustainable post growth pathways the emerging field of ecological macroeconomics aims to address this need and features a number of new macroeconomic modelling approaches this article provides 1 a review of modelling developments in ecological macroeconomics based on the literature and interviews with researchers and 2 an analysis of how the different models incorporate policy themes from the post growth literature twenty two ecological macroeconomic models were analysed and compared to eight policy themes it was found that environmental interactions and the monetary system were treated most comprehensively themes of income inequality work patterns indicators of well being and disaggregated production were addressed with less detail while alternative business models and cross scale interactions were hardly addressed overall the combination of input output analysis with stock flow consistent modelling was identified as a promising avenue for developing macroeconomic models for a post growth economy however due to the wide interpretation of what the economy entails future research will benefit from employing a range of approaches

scale prices and biophysical assessments abstract in a recent forum on biophysical assessments a number of ecological economists expressed serious reservations about the use of prices to assess the appropriate scale of macroeconomic systems while such reservations are warranted the preference for biophysical assessments over prices indicates that many ecological economists are focussing on one notion of scale and neglecting another altogether there are two notions of scale that are critical to achieving sustainable development sd one is the maximum sustainable macroeconomic scale the other is the optimal macroeconomic scale the maximum sustainable scale is the largest macroeconomic scale that can be sustained by a throughput of matter energy that is within the ecosphere s regenerative and waste assimilative capacities the optimal scale is a preferable macroeconomic scale and is one that is not only sustainable but one that maximises the net benefits of economic activity biophysical assessments are needed to determine the maximum sustainable scale because ecological sustainability is a biophysical problem not an economic problem thus it is through biophysical assessments that the necessary restrictions on the incoming resource flow can be calculated and imposed however since the achievement of an optimal macroeconomic scale is an economic problem albeit a constrained economic problem relative prices are required to efficiently allocate the sustainable resource flow so the macroeconomy can adjust to the optimum failure to recognise the two notions of scale and the most appropriate means of their assessment is likely to thwart rather than advance the movement toward sd

analysis of energy embodied in the international trade of uk interest in the role embodied energy plays in international trade and its subsequent impact on energy security has grown as a developed nation the uk s economic structure has changed from that of a primary producer to that of a primary consumer although the uk s energy consumption appears to have peaked it imports a lot of energy embodied in international trade alongside the more obvious direct energy imports the uk has seen increasing dependency on imported fossil energy since the uk became a net energy importer in 2005 in this paper an energy input output model is established to calculate not only the amount of fossil energy embodied in uk s imports and exports but also the sector and country distributions of those embodied fossil energy the research results suggest the following uk s embodied fossil energy imports have exceeded embodied fossil energy exports every year since 1997 uk embodied energy imports through the so called made in china phenomena are the largest accounting for 43 of total net fossil energy imports if net embodied fossil energy imports are considered the gap between energy consumption and production in uk is much larger than commonly perceived with subsequent implications to the uk s energy security

interlocking transactions obstacles precursors or instruments of agrarian capitalism abstract rural labor arrangements often change rapidly and in ways that prevailing theories cannot explain explicit understanding of the exercise of power in rural society sheds considerable light on how and why rural labor arrangements change in the course of economic development this paper shows how different labor tying arrangements embody exclusionary mechanisms that can serve as instruments of both labor management and social control macro political and economic conditions shape the ways in which these mechanisms operate and are in turn influenced by them viewing labor arrangements in this way helps resolve problems confronted by the prevailing theories and allows for a broader understanding of dynamic processes

revisiting asset pricing under habit formation in an overlapping generations economy abstract by incorporating habit formation into an overlapping generations economy we show that the middle aged consumers savings decision has a substantial impact on the equity premium the higher incentive for savings for the middle aged resulting from the habit formation preference causes an even higher demand for bonds and a lower demand for equity which eventually generates a lower risk free rate and a higher required return for holding equity than does the framework of non habit forming models calibration results verify that the habit formation setting together with an olg framework is capable of yielding lower bond returns and higher equity returns than the standard crra utility models and the borrowing constraint imposed on the young aged consumers amplifies the positive effect of habit formation on the equity premium the findings imply that habit formation preferences within the overlapping generations framework under the borrowing constrained economy can provide a more improved explanation of the equity premium puzzle

a monetary minsky model of the great moderation and the great recession abstract steve keen s model of minsky s financial instability hypothesis keen 1995 displayed qualitative characteristics that matched the real macroeconomic and income distributional outcomes of the preceding and subsequent fifteen years a period of economic volatility followed by a period of moderation leading to a rise of instability once more and a serious economic crisis this paper extends that model to build a strictly monetary macroeconomic model which can generate the monetary as well as the real phenomena manifested by both the great recession and the great moderation

capital requirements screening and interlinked sharecropping and credit contracts this paper provides one more rationale for interlinking credit and tenancy contracts in the context of production loans in an environment characterized by a heterogeneous labor pool and imperfect information landlords will have an incentive to avail themselves of screening devices by linking tenancy and credit contracts a screening device can be implemented the equilibrium set of contracts is characterized by a variety of interest rates some of which might be below the market interest rate the interest rate principal schedule is downward sloping with higher ability tenants choosing larger principals at lower interest rates

towards post keynesian ecological macroeconomics the paper starts with a brief criticism of macroeconomic analyses of different schools of thought for their focus on economic growth and maximisation of output this applies to the traditional keynesian approach which has focused on the achievement of sufficient aggregate demand to underpin full employment and full capacity utilisation down playing aggregate supply constraints this also applies to the neoclassical approach including the current new consensus macroeconomics approach which asserts the dominant role of aggregate supply in the long run and where growth is set by the so called natural rate of growth with no concerns over environmental and ecological issues the paper then proposes a different approach to macroeconomic analysis it explicitly acknowledges that economic growth is a double edged sword growth can help to alleviate persistent levels of high unemployment but it can also lead to potentially catastrophic environmental problems building on the monetary circuit theory and the demand led growth theory the paper offers an analysis of the interconnections and interdependence of the economic biophysical and social worlds and by doing it hopes to provide the building blocks for the establishment of post keynesian ecological macroeconomics

why institutional credit agencies are reluctant to lend to the rural poor a theoretical analysis of the indian rural credit market abstract this paper examines why institutional credit facilities remain unable to extend credit to the rural poor analysis indicates that poor peasants at best can offer an entitlement set as a mortgage comprised only of future shares of their harvest which itself is subject to risk consequently lenders can not advance loans without risking extensive loss of loanable funds as the landlords income is subject to the same risk as that of peasants they advance loans to ensure that their own income is not affected by the peasants financial situation an extension of institutional credit to peasants results only in subsidization of landlords

working time reduction policy in a sustainable economy criteria and options for its design abstract reducing per capita consumption particularly amongst high income groups is often deemed necessary to reduce the environmental impacts of the global economy far from implying a necessary reduction in wellbeing some research suggests this could actually improve it as reduced expenditure means a reduced need for income and hence paid work then there is the possibility for average working hours to fall providing increased leisure time in which to pursue happiness through less consumption intensive but more time consuming ways to date however there has been little critical discussion of the details of what policy might need to cover to allow and encourage substantial working time reduction in a way that successfully reconciles these environmental and wellbeing goals this article addresses this gap in the literature it begins by reviewing the conditions under which working time reduction could bring environmental and wellbeing benefits it then presents examples of innovative voluntary working time policies from the netherlands and belgium drawing these elements together the article presents a new green life course approach for working time policy design it argues that as a complement to more conventional working time policies this could be a valuable tool to combine environmental and wellbeing goals

testing between competing models of sharecropping the marshallian approach assumes a prohibitively high cost of monitoring the sharecropper s activities while the monitoring approach argues that landlords stipulate and effectively monitor sharecroppers activities i present new evidence using detailed data collected from eight indian villages most tenants own some land of their own this provides a controlled environment in studying the impact of contractual arrangements the differences in input and output intensities on owned minus sharecropped land of the same household are found to be sizable and significant suggesting a rejection of the monitoring approach and supporting the notion of the marshallian productive inefficiency of sharecropping

capital theory and the measurement of sustainable development an indicator of weak sustainability the measurement of sustainable development is not without considerable difficulties yet this should not detract from the positive advances that can be made in this direction in this paper we present one form that a weak sustainability indicator can take derived from a simple but intuitive savings rule it incorporates the idea that the level of overall capital stock should be non decreasing although subject to qualification at this stage some interesting results emerge from the application of the rule to 18 countries

price uncertainty and trader farmer linkage abstract we show that the pareto superiority of loan repayment in kind within a tied credit arrangement to a cash for cash scheme under uncertain output price depends crucially on the farmer loan demand elasticity and his risk aversion for the risk neutral trader the cash for cash scheme is shown to be pareto dominated by credit tying and the price premium he offers depends on farmer loan demand elasticity

disneyland monopoly interlinkage and usurious interest rates abstract interlinkage between labour and credit markets is interpreted as a consequence of a monopolistic moneylender s attempt to extract consumer s surplus from the borrower by levying a two part tariff this analogy enables us to draw on the literature on non linear pricing to high light issues in agrarian structure the consequence of policy interventions like taxes and minimum wage legislation is studied it is shown that the moneylender will charge usurious interest rates if wages are rigid downwards or there is a tax on agricultural income or borrowers have heterogeneous preferences some geometry for analysing interlinkage is developed and used for deriving some of the results

commodities for the long run using a novel dataset consisting of daily futures prices going back to 1877 we find that returns of commodity futures indices have on average been positive over the long run although return premiums are associated with both carry and spot returns commodity returns in different economic states inflation up down expansion recession vary mostly as a result of moves in the underlying spot price these economic states are important drivers of commodity returns even after conditioning on whether commodity markets are in backwardation or contango the evidence supports commodities as a potentially attractive asset class in portfolios of stocks and bonds

3 d sustainability an approach for priority setting in situation of conflicting interests towards a sustainable development abstract this paper aims to provide a new approach to objectively assess hierarchies and priority setting in the relationship between environmental social and economic sustainability within sustainable development after a literature review several widely used conceptual figures diagrams describing this relationship were assessed using swot analyses in order to identify the major weaknesses in these pictorial descriptions based on the findings a new concept called 3 d sustainability has been developed and is presented visually as well as is described in the text this concept introduces and ranks criteria for the assessment of hierarchies within and conflicts of interests between social environmental and economic sustainability the three dimensions of sustainability these criteria are applied to several existing hierarchies and solutions to conflicts of interests based on the swot analyses the main shortcomings of the widely used conceptual figures were identified as 1 misinterpretation of embeddings 2 misjudgement of equity between the three dimensions of sustainability 3 a lack of expression of limitations and 4 lack of adequate decision support these shortcomings are overcome theoretically and in practice by 3 d sustainability a slightly more complex but conceptually richer figure than the widely used conceptual figures assessed in particular the shift of the burden of proof within the three sustainability dimensions is argued as a main solution the application of the criteria of 3 d sustainability to several real examples indicates its usefulness in decision support while justifying more sustainable hierarchies and solutions in the settlement of conflicts of interests within the three sustainability dimensions

credit and sharecropping in agrarian societies this paper considers a model of linkage between land labor and credit transactions in the context of sharecropping the paper s objectives are a to derive and characterize the equilibrium in a model of a land scarce labour abundant economy under sharecropping given an infinitely elastic supply of identical sharecroppers at a reservation utility and b to demonstrate that in an imperfect market a landlord may offer credit to his tenant sometimes even at a subsidized rate of interest without necessarily insisting that the sharecropper borrow only from him precluding an involuntary linkage between credit and land transations it has been demonstrated that regardless of the presence or absence of linkage or any other control by the landlord as long as he can vary the size of the plot given to a tenant and there are enough potential tenants in equilibrium contracts a tenants utility under sharecropping will be the same as that which he could have obtained as a full time wage laborer this result implies that policies other than land reform will not affect the welfare of tenants

declining discount rates and the fisher effect inflated past discounted future uncertain and persistent real interest rates underpin one argument for using a declining term structure of social discount rates in the expected net present value enpv framework despite being controversial this approach has influenced both the inter agency working group on cost benefit analysis and the uk government s guidelines on discounting we first clarify the theoretical basis of the enpv approach then rather than following previous work which used a single series of u s treasury bond returns we treat nominal interest rates and inflation as co integrated series and estimate the empirical term structure of discount rates via the fisher effect this nests previous empirical models and is more flexible it also addresses an irregularity in previous work which used data on nominal interest rates until 1950 and real interest rates thereafter as we show the real and nominal data have very different time series properties this paper therefore provides a robustness check on previous discounting advice and updated methodological guidance at a time when governments around the world are reviewing their guidelines on social discounting the policy implications are discussed in the context of the social cost of carbon nuclear decommissioning and public health

environmentally sustainable household consumption from aggregate environmental pressures to priority fields of action unsustainable consumption patterns of the north or rather of the global affluent consumers class have been identified by agenda 21 as one of the key driving forces behind the unsustainable development however neither accounting based on the system of national accounts sna nor household economics provide the proper instruments to assess the environmental impact of household decision making eco efficiency assessments as familiar in the business sector provide no appropriate tool for households as an alternative an environmental space based assessment scheme is suggested covering the major pressures on the environment caused by household decisions the methodology is used twice once to analyse the environmental relevance of the main activity clusters of household consumption and once to identify the dominant acts of consumption within each cluster the latter provide the basis for deriving environmental performance indicators a rough analysis of household influence potentials permits to identify housing eating and mobility as the three priority fields for action for minimising the environmental impact of households extending the influence analysis actor matrixes are derived allocating influence and thus responsibility for environmental pressures to different groups of economic agents

tenancy and interlocking markets issues and some evidence abstract it is frequently asserted that the land lease markets in agrarian economies tend to be interlocked with other markets in recent years a number of theoretical models have been constructed to explain and analyze interlinkages of various markets under cropshare tenancy however the empirical basis for such assertions remains very weak this paper reviews the issues discussed in the literature and attempts empirical verification in the specific context of agriculture of bangladesh the evidence presented does not reveal any significant interlinkages of rural markets in bangladesh

a stock flow fund ecological macroeconomic model this paper develops a stock flow fund ecological macroeconomic model that combines the stock flow consistent approach of godley and lavoie with the flow fund model of georgescu roegen the model has the following key features first monetary and physical stocks and flows are explicitly formalised taking into account the accounting principles and the laws of thermodynamics second georgescu roegen s distinction between stock flow and fund service resources is adopted third output is demand determined but supply constraints might arise either due to environmental damages or due to the exhaustion of natural resources fourth climate change influences directly the components of aggregate demand fifth finance affects macroeconomic activity and the materialisation of investment plans that determine ecological efficiency the model is calibrated using global data simulations are conducted to investigate the trajectories of key environmental macroeconomic and financial variables under i different assumptions about the sensitivity of economic activity to the leverage ratio of firms and ii different types of green finance policies

does decreasing working time reduce environmental pressures new evidence based on dynamic panel approach abstract there is a growing interest in the correlation between working time and environmental pressures but prior empirical studies were mostly focused on static methods within limited country groups to fill the gap this study aims to stimulate the discussion by distinguishing between different time periods for developed and developing country groups respectively in particular we contribute to a further understanding of the environmental effects of working time reduction policies by comparing the differences under the dynamic framework of system generalized method of moments we applied this dynamic panel regression approach for 55 countries worldwide over the period 1980 2010 and employing carbon emissions per capita as the environmental indicator in general results confirmed the significant relationship between hours of work and environmental impacts in developed economies although this is not the case for the developing counterparts interestingly the significant correlations for the developed country group turned from positive during the first sub period 1980 2000 to negative during the second sub period 2001 2010 connecting these results with previous literature we proposed the reasons of rebound energy use derived from certain leisure activities which were more energy intensive if excessive non working time provided

graduate education in ecological economics abstract interest in graduate education in ecological economics is increasing however no formal plan of study for a phd in ecological economics has been disseminated the lack of a formal plan is problematic as the field of ecological economics matures interest grows and new programs are being developed this paper attempts to fill a void by creating a program of study addressing the proficiencies a graduate student in ecological economics should have upon completion of his her phd based on the us educational system the plan of study presented in this paper has been developed to make the graduate of an ecological economics program as competitive on the labor market as students awarded traditional economics degrees the plan i describe is created to meet the requirements necessary for a phd in ecological economics further fields of specialization are suggested to complement the core of an ecological economics program to enhance the education process and to give the student with an ecological economics degree a higher level of marketability

an analysis of the s p 500 index and cowles s extensions price indexes and stock returns 1870 1999 this article provides a consistent monthly stock price index from january 1871 through 1999 the broadly defined s p weekly index is reconstructed from 1918 and carried forward as the s p 500 composite index to the present cowles s monthly index is improved in order to provide month end estimates from february 1885 cowles s estimates of dividends and earnings for this index from 1871 are reevaluated and are carried forward until spliced to the s p daily estimates that began in 1957 the result is a monthly index of prices dividends and earnings based on consistent definitions over a period of 130 years

the price of wine abstract using historical price records for bordeaux premiers crus we examine the impact of aging on wine prices and the long term investment performance of fine wine in line with the predictions of an illustrative model young maturing wines from high quality vintages provide the highest financial returns past maturity famous ch teaus deliver growing non pecuniary benefits to their owners using an arithmetic repeat sales regression over 1900 2012 we estimate a real financial return to wine investment net of storage costs of 4 1 which exceeds bonds art and stamps returns to wine and equities are positively correlated finally we find evidence of in sample return predictability

fragmented duopoly theory and applications to backward agriculture abstract the central aim of this paper is to provide a formal description of the idea of market fragmentation which is so widely used to describe markets in backward agriculture we begin by describing a fragmented duopoly in which each seller has a captive set of customers and there is a non captive set who may buy from either seller the nash cournot equilibria of the system are analyzed and then the model is generalized to allow for the endogenous determination of the captive sets the subgame perfect equilibrium of the model provides a useful background for studying familiar topics like fragmentation interlinkage and disguised unemployment from a new point of view

ecological monetary economics a post keynesian critique the monetary analysis of some ecological economists currently appears to be mostly articulated around the following core a stationary economy and a fortiori a degrowth economy is incompatible with a system in which money is created as interest bearing debt to question the relevance of the debt money positive interest rate output growth nexus this paper adopts a critical stance towards the currently emerging ecological monetary economics from the standpoint of another strand of heterodox economics the post keynesian approach in its current state ecological monetary economics is at odds with post keynesian economics in its analysis of the money growth relationship this will be shown using the theory of endogenous money and a simple cambridgian kaleckian model where debt money and a positive interest rate are compatible with a full stationary economy

sharecropping and the interlinking of agrarian markets one of the often noted features of less developed agrarian economies is the existence of interlinkages among the land labor credit and product markets the landlord is often the supplier of credit he frequently purchases and markets the output of the tenant farmers and often sells raw materials and even consumption goods to his tenant farmers how can this phenomenon be explained what are the welfare consequences of attempts to restrict these practices which often seem to constitute restraints on free trade these are the questions to which this paper is addressed a general set of arguments applicable to both competitive and noncompetitive environments are presented to situations where all the terms of the contract are determined in an optimal way as well as to situations where many of the terms are specified institutionally section i examines interlinked credit and tenancy contracts section ii examines interlinked marketing and tenancy contracts section iii points out the possible interlinking between labor contracts and consumption goods markets and section iv presents the different equilibrium frameworks discussed in the paper such as monopoly monopsony competition and equilibria with surplus labor

credit and share cropping comments on braverman and srinivasan abstract the monitoring cost is introduced in an otherwise braverman srinivasan model of share cropping it is shown that a possibility of excess applicants equilibrium arises and in such a case credit subsidization policy can improve the welfare of the tenant

sustainable growth criteria minimum benchmarks and scenarios for employment and the environment abstract the relationship of economic growth and environmental impact has spurred fierce debates between growth optimists referring to the phenomenon of the environmental kuznets curve and pessimists referring to the limits to growth however no operational set of simple criteria has been developed so far to assess the sustainability of a given growth pattern this is all the more true for measures combining environmental and social criteria the paper undertakes to sketch out such criteria and to assess them by applying them to transdiciplinary sustainability scenarios and model simulations with panta rhei one of the most complex models of the german economy theoretical considerations as well as the empirical work with the model demonstrate that there are indeed trade offs between economic growth and environmental impacts and a positive correlation of growth and employment nonetheless it is still possible to develop carefully orchestrated strategies that combine economic competitiveness low unemployment rates and an easing of the pressure on the environment social and technical innovation reduced working time a modernised social security system green taxes and salary increases proportional to labour productivity growth are essential parts of any such strategy the triple effectiveness of such strategies regarding environmental social and economic sustainability is demonstrated by the model runs

productivity and distribution under cropsharing tenancy abstract this paper develops a model of sharecropping assuming tenant autonomy competitive behavior of landlords and laborers and endogenously determined wage and share rental rates the coexistence of wage labor and sharecropping is explained in terms of their incentive labor process and risk sharing characteristics sharecropping serves as a surrogate for the direct supervision of the labor process its incidence is shown to rise in the presence of unemployment at a subsistence wage the model implies that the abolition of tenancy will raise output raise labor income and reduce land income

rural credit markets and institutions in developing countries lessons for policy analysis from practice and modern theory this article presents evidence of the failure of government intervention in rural credit markets of ldcs in the past three decades it then shows how lessons for policy analysis can be drawn from modern theory particularly those theories focussing on credit rationing in competitive markets and interlinking of credit contracts with labor and land contracts the article outlines the policy implications of these theories and finds them insufficient to account for the empirical evidence it contends that a more systematic and rigorous analysis of institutions and institutional environments is essential for understanding and implementing effective policy reforms of rural credit markets it presents suggestions for undertaking such an analysis

does slow growth lead to rising inequality some theoretical reflections and numerical simulations this paper explores the hypothesis most notably made by french economist thomas piketty that slow growth rates lead to rising inequality if true this hypothesis would pose serious challenges to achieving prosperity without growth or meeting the ambitions of those who call for an intentional slowing down of growth on ecological grounds it would also create problems of social justice in the context of a secular stagnation the paper describes a closed demand driven stock flow consistent model of savings inequality and growth in a macroeconomic framework sigma with exogenous growth and savings rates sigma is used to examine the evolution of inequality in the context of declining economic growth contrary to the general hypothesis we find that inequality does not necessarily increase as growth slows down in fact there are certain conditions under which inequality can be reduced significantly or even eliminated entirely as growth declines the paper discusses the implications of this finding for questions of employment government fiscal policy and the politics of de growth

the growth discourse growth policy and sustainable development two thought experiments abstract this paper addresses three aspects of growth the discourse the policy and the impacts the growth discourse claims that the central factor for social economic political and environmental progress is economic growth it is assumed to create wealth and provide the necessary means for social and environmental purposes on the basis of the growth discourse different growth policies can be derived based on different economic and political ideologies in order to reveal the implications of de facto degrowth two thought experiments are conducted for physical and economic end to growth strategies the latter is capable of meeting environmental objectives but implies significant social tensions and hardships and calls for transition strategies consisting of carefully designed steps

an inquiry into quasi credit contracts the role of reciprocal credit and interlinked deals in small scale fishing communities in agrarian village societies beset with many hazards and uncertainties people evolve various means of coping with risk what is perhaps less known is that credit transactions can sometimes serve the function of reducing risk in such societies this article is concerned with examining several insurance motivated credit arrangements in small scale fishing communities a hunger insurance mechanism of reciprocal credit and a system of interlinked contracts aimed at insuring against risks in the spheres of labour and marketing relations will be extensively dealt with moreover the concept of triadic relationships will be shown to have special relevance in the case of traditional insurance arrangements aiming at controlling problems of moral hazard

does credit create a growth imperative a quasi stationary economy with interest bearing debt abstract this paper addresses the question of whether a capitalist economy can ever sustain a stationary or non growing state or whether as often claimed capitalism has an inherent growth imperative arising from the charging of interest on debt we outline the development of a dedicated system dynamics macro economic model for describing financial assets and liabilities in a stock flow consistent framework falstaff and use this model to explore the potential for stationary state outcomes in an economy with balanced trade credit creation by banks and private equity contrary to claims in the literature we find that neither credit creation nor the charging of interest on debt creates a growth imperative in and of themselves this finding remains true even when capital adequacy and liquidity requirements are imposed on banks we test the robustness of our results in the face of random variations and one off shocks we show further that it is possible to move from a growth path towards a stationary state without either crashing the economy or dismantling the system nonetheless there remain several good reasons to support the reform of the monetary system our model also supports critiques of austerity and underlines the value of countercyclical spending by government
