the political economy of agriculture for development today the small versus large scale debate revisited the role of agriculture in economic development and the development politics of promoting smallholder versus large scale agriculture have both been at the center of a long lasting and controversial debate using an innovative methodology which combines a value chain approach with input output analysis the growth multipliers and productivity of both farm types in guatemala are analyzed results show that smallholder agriculture has the same potential to stimulate output growth as large scale agriculture smallholder value chains include mainly informal sectors and create more jobs than commercial agriculture therefore a reorientation of agricultural and land policies toward small scale food producers and within a comprehensive policy of integrated rural development is not only necessary in terms of social equity but also for boosting economic development

on measuring the quality of life abstract it is widely recognized that per capita income is not an adequate indicator of aggregate well being it has thus become customary to use a range of socioeconomic indices for assessing the quality of life in a society in this article we extend measures of general well being in current use by including ordinal indices of political and civil liberties and we provide a ranking of the world s poorest countries on the basis of the borda rule we then compare improvements in socioeconomic performance with the availability of political and civil liberties during the decade of the 1970s and observe that improvements in per capita national income life expectancy at birth and infant mortality are positively correlated with the extent of political and civil liberties enjoyed by citizens while improvements in literacy are negatively correlated with these liberties

the inverse relationship between size of land holdings and agricultural productivity the important relationship between the size of land holdings and agricultural productivity in developing countries has been debated intensely from early soviet debates to the extensive literature generated by the release of farm management survey fms data in india the question of returns to scale and input productivities primarily for land in traditional agriculture has been confused and clouded by strong positions and ideological predilections bhagawati and chakravarty saini 1969 and bharadwaj provide extensive bibliographies on the theoretical and empirical aspects of this problem in the indian context briefly sen 1964 1966 mazumdar 1963 1965 c h h rao 1966 1970 khusro saini 1971 bhattacharya and saini more or less endorse an inverse relationship between the land size and its productivity a p rao 1963 and rudra and bandhopadhyay do not believe in the existence of an inverse relationship and argue that no systematic relationship can be established between any two variables describing land size and productivity bharadwaj and others dismiss the statistical validity of an inverse relationship but generally accept it as a stylized fact the approach used in these statistical studies is to employ aggregate average or farm level data within a village or among different villages for all crops or a few specific ones various concepts of productivity and input variables are used the actual regressions use linear or log linear functional forms using the pooled fms data for several states in south india this paper makes an attempt to reexamine in a more general way the relationship between the size of land holdings and agricultural productivity this study employs the transcendental logarithmic translog function to formalize the relation between output and an arbitrary number of inputs the translog function is not locally constrained by assumptions of homogeneity or additivity estimates of output elasticity with respect to land size for various values of cooperating inputs will indicate whether the alleged inverse relationship holds in any or all circumstances

positively sloping marginal revenue ces utility and subsistence requirements the possibility that marginal revenue may possess a positive slope has long been recognized as important in her classic the economics of imperfect competition joan robinson 14 accorded considerable significance to the possibility and investigated it at length despite robinson s insights upward sloping marginal revenue functions remained largely a curiosity widely regarded as an overly stringent perversity unlikely to occur in reality considerable doubt was cast on this view when in 1980 a a walters 20 reported the presence of positively sloping marginal revenue in the pricing policies of the port of singapore the case for upward sloping marginal revenue was furthered by formby layson and smith s 8 straightforward demonstration that upward sloping marginal revenue schedules are very easily produced and can never be ruled out because simple parallel shifts in strictly convex demand and or rotations always transform demand schedules with downward sloping marginal revenue into ones with positively sloping schedules this strongly suggests that no theoretically reasonable restrictions can be placed on the behavior of marginal revenue because to do so would rule out such simple transformations as parallel shifts or rotations in demand such restrictions would be too stringent to be acceptable upward sloping marginal revenue has found important application in such diverse topics as catastrophe theory 3 third degree price discrimination 13 dual equilibria and monopolistic competition 11 specific taxes and quality 2 and international trade 7 2 the significance of non monotonic marginal revenue functions is further underscored by the fact that the presence of upward sloping marginal revenue significantly affects the sign of comparative static results for example see 18 260 15 16 2 a shortcoming of previous analyses lies in the fact that they draw conclusions from consideration of slope level and curvature of the demand schedule alone the behavior of marginal revenue derived directly from the more fundamental basis of utility theory has not been examined this paper takes up this question employing wold s theorem to analyze marginal revenue

modeling agricultural growth multipliers agriculture s potential as an engine of third world growth depends in large part on the size of the production and consumption linkages it stimulates in rural regions current estimates of agricultural growth multipliers within rural regions vary widely not only because economic structures differ across regions but also because the array of fixed price models most commonly used embody widely differing basic assumptions among fixed price models the semi input output formulation projects the most plausible multipliers but even they overstate the magnitude of growth multipliers by 10 to 25 according to the price endogenous model developed here

economic relationship between access to land and rural poverty in nepal in the present socio economic structure of nepal land is the main source of income and consumption for the majority of nepalese this study analyses the economic relationship between access to land and poverty in nepal by establishing the link between land and consumption as well as land and income a generalised additive model gam and ordinary least squares ols demonstrate that greater access to land increases income and consumption of the household and thereby reduces poverty the significant marginal value of land for both consumption and income implies that an effective land reform policy could well be an effective approach to alleviate rural poverty however land reform must come as part of a larger overhaul cluster analysis shows that land reform should target appropriate subgroups within the community in order to differentiate those who would make use of the extra land from those who would not and apply appropriate strategies to each subgroup it reveals the importance of subgroups in determining an appropriate strategy for tackling poverty

farm size land yields and the agricultural production function an analysis for fifteen developing countries abstract the paper analyzes the relationship between factor inputs land yields and labor productivity for farms of different size on the basis of fao farm management data for 15 developing countries for all but three countries a strong negative correlation is found between farm size on the one side and factor inputs and yields per hectare on the other the fitting of unconstrained production functions to the above data suggests that in only few cases the decline in yields for increasing farm size can be attributed to decreasing returns to scale the higher yields observed in small farms are mainly to be ascribed to higher factor inputs and to a more intensive use of land therefore where conspicuous labor surpluses exist the superiority of small farming provides solid arguments in favor of land redistribution such an agrarian reform would determine higher output higher labor absorption and a more equitable income distribution thus contributing in a decisive manner to the alleviation of rural poverty the paper also provides estimates of cross sectional production functions for the 15 countries analyzed empirical relations are found between the output elasticities of land labor and intermediate inputs and physical indicators of their scarcity the paper concludes by proposing a simple method for deriving a long term production function for agriculture

the index of sustainable economic welfare isew as an alternative to gdp in measuring economic welfare the results of the austrian revised isew calculation 1955 1992 abstract although the inadequacy of gdp to measure economic welfare is widely accepted theoretically it is still used as the key indicator for economic policy this article s aim therefore is to give some empirical evidence to the theoretical critique economic welfare or at least its change over time is estimated by the index of sustainable economic welfare isew which takes account of gdp unpaid household labor social costs environmental damage and income distribution the concept of the isew which was originally developed by herman daly and john cobb is entirely reformulated with special regard to questions of inner consistency and clarity in structure as an illustration the methods of the calculation in the austria case study and its results are presented the main result is that gdp and economic welfare as measured by the isew differ significantly up until the 1970s gdp only slightly overestimated the growth of economic welfare but since then it has been completely misleading while gdp continues to rise sustainable economic welfare has been stagnating since the middle of the 1980s the main causes have been growing future welfare reductions increasing income inequality and a stagnation in the value of unpaid household labor as gdp neglects those aspects it systematically misinterprets economic welfare however the isew does not intend to simply replace gdp as a unique welfare measure but should form part of a more holistic social reporting system

access to capital and its impact on agrarian structure and productivity in kenya access to capital and its distribution across agents can profoundly shape the structure and performance of an agrarian market economy it is conceptually useful to distinguish between ex ante and ex post capital access ex ante capital access denotes the ability of agents to finance production costs e g labor and purchased inputs costs which must be paid ex ante that is prior to the actual realization of production ex post capital access that is access to capital after the realization of the production process is of particular importance as an insurance substitute in low income agrarian economies where contingency markets are imperfect buoyant ex post capital access would permit an individual to stabilize consumption year to year even as production fluctuates annually a number of theoretical models have ex

well being and or quality of life in eu countries through a multidimensional index of sustainability abstract the aim of my paper is to demonstrate that sen s theory of well being can be applied to make the concept of sustainable human development operational through the building of a multidimensional index of sustainability which takes into account at the same time economic social and environmental variables this index may be considered an alternative to the current measures of welfare sustainability since not only conventional measures such as gdp but also multi attribute indices such as human development index hdi genuine savings index of sustainable economic welfare isew etc are found to be inadequate to make the concept of sustainable development operational therefore the limitations of these measures of welfare sustainability justify the search for a new index of sustainability this index will show at the operational level how sen s theory of well being can be useful to sustainable development it was applied to eu countries using the standardised deviation methodology being the closest and most suitable methodology to be adopted for building multidimensional indices the factor analysis methodology will also be used in my paper lastly the comparison between sen s trend of sustainability and gdp trend index number which are both of them applied to italy will show how much the criticisms and the limitations directed towards the indicator of gdp are founded

agrarian structure and agricultural practice typology and application to western sudan a typology of models that explain patterns of variation in farm endowments and farm practices and yields shows that insecurity in renting land financing constraints and the absence of insurance generate patterns of factor use quite different from the famous inverse relationship caused by labor supervision problems one might expect to observe positive relationships between wealth and yields village level data from western sudan confirm that such positive relationships are not a theoretical curiosity wealthy farmers have higher levels of output per hectare because they use more labor per hectare insurance and financing constraints appear to be the crucial market failures

missing ness in action selectivity bias in gps based land area measurements land area is a fundamental component of agricultural statistics and of analyses undertaken by agricultural economists while household surveys in developing countries have traditionally relied on farmers own potentially error prone land area assessments the availability of affordable and reliable global positioning system gps units has made gps based area measurement a practical alternative nonetheless in an attempt to reduce costs keep interview durations within reasonable limits and avoid the difficulty of asking respondents to accompany interviewers to distant plots survey implementing agencies typically require interviewers to record gps based area measurements only for plots within a given radius of dwelling locations it is therefore common for as much as a third of the sample plots not to be measured and research has not shed light on the possible selection bias in analyses relying on partial data due to gaps in gps based area measures this paper explores the patterns of missingness in gps based plot areas and investigates their implications for land productivity estimates and the inverse scale land productivity relationship using multiple imputation mi to predict missing gps based plot areas in nationally representative survey data from uganda and tanzania the paper highlights the potential of mi in reliably simulating the missing data and confirms the existence of an inverse scale land productivity relationship which is strengthened by using the complete multiply imputed dataset the study demonstrates the usefulness of judiciously reconstructed gps based areas in alleviating concerns over potential measurement error in farmer reported areas and with regards to systematic bias in plot selection for gps based area measurement

inverse productivity or inverse efficiency evidence from mexico abstractusing a unique panel data set from rural mexico we find strong evidence of a negative relationship between farm size and both productivity and technical efficiency large farms not only have a lower value of output per hectare than small farms they also produce further from the efficiency frontier our findings suggest that in spite of the ongoing transformation of agricultural supply chains and economists recommendations for small farmers to exit crop production there may be sustained advantages for smallholder farms our analysis offers new insights into inverse farm size relationship the productivity efficiency relationship and the use of stochastic frontier techniques

access to capital and agrarian production organisation there are two problems both universal that entrepreneurs in any economy must contend with firstly an agent generally has access only to a limited amount of working capital secondly workers hired by an agent are subject to moral hazard and this necessitates their supervision this paper models for an agrarian economy the constraints imposed on entrepreneurs activities by these two problems and endogenously determines the various organisational forms of production as well as the allocation of resources that will obtain with a simple model we endeavour to explain a diverse set of empirical observations pertaining to the less developed countries in terms of the general processes that determine the distribution of income among the various agents and the hierarchical relationships that develop among them agricultural production typically involves a period of several months between the time the inputs are purchased and the time the output is marketed access to working capital and hence to the credit market thus plays an important role in a farmer s production decisions the distribution of access to credit in turn tends to be an important determinant of income distribution in poor agrarian economies credit is invariably rationed according to the ability to offer collateral the amount of working capital a farmer can mobilise therefore depends on the amount of land he owns which is often a good proxy for his overall wealth and thus his ability to offer collateral further since hired hands have a propensity to shirk they need to be supervised and therefore the

household resources transaction costs and adjustment through land tenancy this paper examines the role of household endowments of imperfectly tradeable factors of production e g male female child labor and draft animals on land leasing an explicit attempt is made to account and test for the role of transaction costs on the incidence and extent of adjustment taking place through the land lease market the econometric model is implemented using pooled data from six villages in the semiarid region of india the results confirm the significant role of nontradeable family endowments and indicate the presence of frictions in the land tenancy market

the law of demand positive sloping marginal revenue and multiple profit equilibria this paper demonstrates that the conditions for a positively sloping marginal revenue curve are much less stringent than is generally recognized simple transformations of any well behaved convex demand function can easily result in a demand for which marginal revenue is positively sloping for this reason positively sloping marginal revenue functions must be considered whenever convex demand functions are analyzed the existence of positively sloping marginal revenue makes multiple profit equilibria for the firm a very real possibility

vertical integration in a monopolistically competitive industry abstract this paper considers forward vertical integration by a monopolist producer of an intermediate good when the downstream industry is monopolistically competitive alternative methods of vertical control are considered in addition to the usual input mark up these include franchise fees royalties and resale price maintenance it is found that these methods in combination achieve perfect or near perfect replication of the outcome under full vertical integration the case where downstream products are differentiated by location in a circular space is studied in detail and alternative outcomes are ranked according to their social desirability

the human development index a critical review since 1990 the united nations development programme undp has published a series of annual human development reports hdrs in which the human development index hdi is computed for each country this index has become an important alternative to the traditional unidimensional measure of development i e the gross domestic product although the index still fails to include any ecological considerations it has broadened the discussion surrounding the evaluation of development unfortunately over the years the hdrs seem to have become stagnant repeating the same rhetoric without necessarily increasing the hdi s utility this paper evaluates how well these reports have lived up to their own conceptual mandate and assesses the ability of the hdi to further the development debate we find that the reports have lost touch with their original vision and the index fails to capture the essence of the world it seeks to portray in addition the index focuses almost exclusively on national performance and ranking but does not pay much attention to development from a global perspective we propose the incorporation of three simple modifications for the index as a first step to overcome these shortcomings 1998 elsevier science b v all rights reserved

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

land reform as commenced business the evidence against stopping abstract in the new paradigm institutions are long term endogenous thus the aims of land reform must be compatible with replace or substitute for initial incentives and power structures many reforms e g compulsory collectives are not redefinition of land reform is therefore needed yet the case for private land redistribution with ceilings remains the inverse relationship rests firmly on lower cost labor transactions in small farms though large but competitive transport or processing firms which enjoy lower cost capital transactions may be needed crucial is the impact of the postreform structure on livelihoods especially for the growing rural majority near landless workers new style market based reforms have potential probably best combined with old style ceilings substantial compensation with urban taxpayers sharing costs alternative off farm prospects and progressive taxes on large landholdings or bequests

wealth weather risk and the composition and profitability of agricultural investments despite the growing evidence that farmers in low income environments are risk averse there has been little empirical evidence on the importance of risk in shaping the actual allocation of production resources among farmers differentiated by wealth the authors use panel data on investments in rural india to examine how the composition of productive and nonproductive asset holdings varies across farmers with different levels of total wealth and across farmers facing different degrees of weather risk income variability is a prominent feature of the experience of rural agents in low income countries the authors report evidence based on measures of rainfall variability that the agricultural investment portfolio behavior of farmers in such settings reflects risk aversion due evidently to limitations on consumption soothing mechanisms such as crop insurance or credit markets the authors results suggest that uninsured weather risk is a significant cause of lower efficiency and lower average incomes a one standard deviation decrease in weather risk measured by the standard deviation of the timing of the rainy season would raise average profits by up to 35 percent among farmers in the lowest wealth quartile moreover rainfall variability induces a more unequal distribution of average incomes for a given distribution of wealth wealthier farmers are willing to absorb significant risk without giving up profits to reduce production risk smaller farmers have to invest their limited wealth in ways that reduce their exposure to risk at the cost of lower profit rates the authors found that at high levels of rainfall variability differences in rates of profit per unit of agricultural assets were similar across classes of wealth but over the sample range of rainfall variability these rates of profit were always higher for the poorer farmers than for the wealthier ones suggesting that the disadvantages of small farmers in risk diffusion are more than offset by their labor cost advantage

how well do tree plantations comply with the twin targets of the clean development mechanism the case of tree plantations in tanzania the clean development mechanism cdm of the kyoto protocol is supposed to provide both carbon mitigation and poverty reduction this article reports from a model based study of market related carbon leakage and poverty reduction in the wake of a cdm tree planting project in tanzania a tree plantation was incorporated in a computable general equilibrium cge model with income differentiated household segments the study focused on sensitivity of carbon leakage and income distribution to different project ownerships and carbon premium allocations it turned out that the project value in terms of carbon premium has clear shortcomings as indicator of induced gdp growth and poverty alleviation the non poor rural and urban households benefit considerably more than the poor households however rising household income in all domestic project ownership arrangements increases demand for food raises use of fertilizer and crop yields a carbon cycle module for agricultural land use was incorporated in the cge model showing an increased carbon sequestration in agricultural soil representing a negative leakage through markets in the range of 60 120 of the certified emissions reductions as registered in the cdm tree plantation project

district level economic linkages in kenya evidence based on a small regional social accounting matrix abstract this paper explores the nature and extent of the economic linkages in a small regional economy defined by a market center and its hinterland in kenya the analysis is based on a set of income and employment multipliers derived from a social accounting matrix estimated for the region issues considered include the impact of production activities on regional value added and employment the influence of sectoral production on the level of household income and the impact of household expenditure on regional value added and the relative significance of production and consumption linkages in terms of stimulating aggregate income the above questions are examined under the assumption of complete excess capacity in regional production and under the assumption of supply constraints in agriculture the usefulness of the analysis for district level economic planning is demonstrated

the relation between farm size and farm productivity the role of family labor supervision and credit constraints abstract the paper shows that if the performance of hired farmhands is affected by supervision from family members and if the availability of credit is dependent on the amount of land owned then a systematic positive or negative relationship between per acre yields and farm size will prevail a model with no supervision effects on labor productivity would predict that yields are unaffected by farm size the paper also investigates the relation between land utilization and owned holding size when land rental possibilities are limited results are shown to be compatible with various observed patterns in ldcs

corporations and local economies in the brazilian amazon the impacts of the mining sectors scheduled investments in southeastern para 2004 2010 southeastern para is an extraordinarily dynamic region there were large cattle ranching projects financed in the 1960s expansion of peasant agriculture mineral projects and gold prospecting followed the ranching projects also important structural transformations reinforced the role of the urban centres and the local rural bases in the logistics of new economic sectors conditioned by the presence of companhia vale do rio doce cvrd in the region since 1985 this article presents the results of an input output analysis of the investment programme of cvrd from year 2004 up to 2010 the main findings are that the mineral sector has achieved a considerable influence over the economy of southeastern para so that during the cycle of investments each 1 in the growth of the mineral production creates growth possibilities of about 0 83 for the agricultural sector and about 0 86 for the local urban sectors considering just the production growth a percentile point will imply growth at respectively 0 73

ethics economics and environmental management individuals derive utility from their access to resources provided by the biosphere through the satisfaction of a number of needs and necessities these needs however cannot often be met simultaneously since they compete with each other this conflict is not just relevant at an individual or even intragenerational level indeed it implies a number of uncertainties and irreversibilities into the future which should not be left to oblivion from an extended anthropocentric ethical position in which only human beings have immanent value and are therefore subjects of moral consideration the identification of economic values can be of great use to allocate resources and make decisions on the environment economic analysis provides a number of decision tools than can be used to optimise efficiency and equity the purpose of this paper is to reflect on some of the ethical constraints to the ability of conventional economic valuation techniques to inform decision making processes affecting the environment it will be argued that depending on the stage of development some environmental and natural assets might well be seen as a common heritage either from a natural or a cultural viewpoint rather than just a pool of economic resources that could be used to satisfy basic needs and depleted or transformed accordingly whether directly or indirectly furthermore this boundary is not static the same environmental asset will be demanded as a resource at lower stages of development both individual and socially and as a part of the common heritage at a later stage again individual and socially in the former the use of conventional methods to value environmental goods and services will be warranted whereas this would not be the case in the latter we will also stress upon the fact that this is something quite different from the approach taken in social project appraisal where the introduction of efficiency prices and distributive factors also provides a move from individual to social welfare maximization but without breaking away from the market logic

the future of small farms trajectories and policy priorities summary while smallholder development has in the past led to reductions in poverty and hunger does this still apply in today s more globalized world this paper reviews the debates on the contemporary role of agriculture in development and the case for small farms in light of the rise of supermarkets lower commodity prices and liberalized trade agricultural research funding environmental change hiv aids and changing policy ideas although the answers vary greatly by context for many low income countries smallholder development remains a key option the policy agenda however has changed in addition to providing public goods the growing challenge is to overcome market failures which is largely a matter of institutional innovation

political macroeconomics a survey of recent developments the paper surveys political macroeconomics covering its development from rogoff s conservative central banker to the most recent discussions of monetary policy and institutional design topics include the inflation stabilization trade off central bank independence with escape clauses and overruling with costs inflation targets performance contracts for monetary authorities and the consequences of output persistence for these issues further topics are the political business cycle when output is persistent the political macroeconomics of fiscal policy the government spending bias and the game theoretic interaction between fiscal and monetary policy all work is discussed within a coherent analytical framework

the build up of local sustainable development politics a case study of company leaders in france abstract the purpose of this study is to examine business leaders perceptions on sustainable development and their expectations about local governments using a questionnaire on a cross section of 32 french business leaders we examine the following questions can issues related to sustainable development extend beyond questions of profit and future economic dynamism the modern global economic crisis in combination with the ongoing ecological one makes regional attractiveness more topical than ever if local governments invest in sustainable development policy it might satisfy not only citizens but also firms in the territory while attracting new ones as well to determine if firms are really interested in such a policy as well as understand their expectations this research undertook interviews with 32 business leaders we found that local governments should act with firms as partners to increase resilience and sustainability the expectations of business leaders and their sensitivity to sustainable development suggest that sustainable development policies could improve the attractiveness of a local economy especially in the context of the current environmental and economic crises

comparing augmented sustainability measures for scotland is there a mismatch we estimate and compare two empirical measures of the weak sustainability of an economy for the first time the change in augmented green net national product gnnp and the interest on augmented genuine savings gs yearly calculations are given for each measure for scotland during 1992 1999 augmentation means including using projections to 2020 changed production possibilities enabled by exogenous technical progress or changing oil prices the change in augmented gnnp and the interest on augmented gs are both always positive showing no sustainability problem for scotland then according to the assumptions underlying our weak sustainability calculations however the former greatly exceeds the latter even when macroeconomic fluctuations are taken into account this is a mismatch which poses an unresolved problem with the theory resolving it may require respecifying the utility functions used in mainstream growth theory

should african rural development strategies depend on smallholder farms an exploration of the inverse productivity hypothesis in africa most development strategies include efforts to improve the productivity of staple crops grown on smallholder farms an underlying premise is that small farms are productive in the african context and that smallholders do not forgo economies of scale a premise supported by the often observed phenomenon that staple cereal yields decline as the scale of production increases this paper explores a research design conundrum that encourages researchers who study the relationship between productivity and scale to use surveys with a narrow geographic reach when policy would be better served with studies based on wide and heterogeneous settings using a model of endogenous technology choice the authors explore the relationship between maize yields and scale using alternative data since rich descriptions of the decision environments that farmers face are needed to identify the applied technologies that generate the data improvements in the location specificity of the data should reduce the likelihood of identification errors and biased estimates however the analysis finds that the inverse productivity hypothesis holds up well across a broad platform of data despite obvious shortcomings with some components it also finds surprising consistency in the estimated scale elasticities

household composition labor markets and labor demand testing for separation in agricultural household models this paper tests the separation of farm labor supply and labor demand decisions using the observation that household composition is an important determinant of farm labor use with nonseparation after assessing the conditions under which the test has power against several alternatives an empirical model is developed to test the proposition that farm employment is independent of family composition the model is estimated on a data set from rural java the null hypothesis that farm labor allocation decisions are independent of household structure is not rejected the results are robust to different specifications of the labor demand function copyright 1992 by the econometric society

on price risk and the inverse farm size productivity relationship abstract the oft observed inverse relationship between farm size and productivity has elicited several explanations having important policy and theoretical implications using advances in the analysis of price risk effects on producer behavior and a simple two period model of an agricultural household that both produces and consumes under price uncertainty at the time labor allocation decisions are made this paper demonstrates analytically that a non degenerate land distribution and price risk can together produce an inverse relationship even absent any of the more common explanations empirical evidence from madagascar confirms the plausibility of this intuitive explanation for the phenomenon

values ideology and politics in ecological economics abstract ecological economics is built on a value commitment to study environmental issues and to contribute constructively to a more sustainable development path however many ecological economists still hesitate it appears to depart too much from other scholars by openly addressing issues of values and ideology in this essay the role of the scholar s orientation with respect to values and ideology is addressed it is observed that not only scholars but also actors in society are guided by their ideological orientation this leads to the idea that some of the weaknesses of economic man and profit maximising firm assumptions can be mitigated by introducing a political economic person and a political economic organisation

steps towards indicators of sustainable development linking economic and ecological concepts abstract conceptions of defining and measuring sustainable development can broadly be placed in two categories weak and strong sustainability the concept of weak sustainability is based on neo classical economic theory and assumes that manufactured and natural capital are close substitutes this means that costs of environmental deterioration e g forest damage can be compensated by benefits from manufactured capital e g income thus environmental damages are valued in monetary units the concept of strong sustainability denies the degree of substitution that weak sustainability assumes at least for some critical elements of natural capital this paper pledges for strong sustainability indicators especially for critical loads and critical levels since the costs and benefits of avoiding critical impacts have to be taken into account a combination of strong and weak sustainability indicators means a linkage of ecological physical and economic monetary approaches should be suggested

strategies to increase agricultural productivity and reduce land degradation evidence from uganda this paper estimates a structural econometric model of household decisions regarding income strategies participation in programs and organisations crop choices land management and labour use and their implications for agricultural production and soil erosion based upon a survey of over 450 households and their farm plots in uganda many factors have context specific impacts and involve trade offs between increasing production and reducing land degradation government agricultural extension and training programs contribute to higher value of crop production in the lowlands but to soil erosion in the highlands by contrast non governmental organization ngo programs focusing on agriculture and environment help to reduce erosion but have less favourable impacts on production in the lowlands education increases household incomes but also reduces crop production in the lowlands poverty has mixed impacts on agricultural production depending on the nature of poverty smaller farms obtain higher crop production per hectare while households with fewer livestock have lower crop production population pressure contributes to agricultural intensification but also to erosion in the densely populated highlands several household income strategies contribute to increased value of crop production without significant impacts on soil erosion we find little evidence of impact of access to markets roads and credit land tenure or title on agricultural intensification and crop production and land degradation in general the results imply that the strategies to increase agricultural production and reduce land degradation must be location specific and that there are few win win opportunities to simultaneously increase production and reduce land degradation

internal consistency of choice internal consistency of choice has been a central concept in economics decision theory and social choice this idea is essentially confused we cannot determine whether a choice function is consistent without referring to something external to choice e g objectives values the standard results have to be reexamined in this light kenneth j arrow s general possibility theorem is extended in this paper without demanding any internal consistency of social choice or any notion of social rationality copyright 1993 by the econometric society

land distribution and international agricultural productivity the unequal distribution of agricultural land is often cited as a source of inefficiency in agriculture previous cross country studies of agricultural productivity differences though have not considered land inequality this article addresses this issue by using cross country data on inequality in operational holdings of agricultural land from deininger and squire 1998 in an estimation of an agricultural production function the gini coefficient for land holdings is found to have a significant negative relationship with productivity this is consistent with the existence of heterogeneity in productivity by farm size within countries a one standard deviation drop in the gini coefficient implies an increase in productivity of 8 5

macroeconomic measures of sustainability this paper reviews the policy need for indicators of sustainable development and the impetus behind recent moves to establish official indicators the range of indicators available from current economic theory is then examined these measures may be divided into those based on flows and those based on stocks flow based measures are essentially attempts to adjust net national product to transform it into an indicator of sustainability stock based measures revolve around the concept of the natural and man made capital stocks we also consider the idea of safe minimum standards as a sustainability indicator the paper concludes that no currently available single measure of sustainability is likely to be adequate

dual equilibria and discontinuous response in monopolistic competition with two classes of consumers the possibility of a convex industry demand function s leading to two local profit maxima for a monopolist supplier is found to extend to a model of monopolistic competition where two classes of consumers are distinguished by their relative demand for the industry s products a long run free entry industry equilibrium is defined and discontinuous responses to changes in parameters are analyzed some applications are given and the existence of dual equilibria is shown to be a possibility

level playing fields and laissez faire postliberal development strategy in inegalitarian agrarian economies focusing on the rural sector in latin america this paper explores the microeconomic linkages between distribution and growth which drive the possible reproduction of rural poverty over time the result of this exploration is a neostructuralist perspective which argues that actually existing laissez faire agrarian economies do not present a level playing field and that low wealth farms face disadvantages which tend to reproduce or even deepen sectoral inequality the paper then tries to identify the sorts of public policy and collective action which might modify the nature of growth and distribution in post liberalization agrarian market economy

behavioural and material determinants of production relations in agriculture in this essay we develop a framework for analysing the major institutions governing the production and exchange of output and the primary factors of production in rural areas the analysis incorporates general considerations of risk and information constraints jointly with the principal material attributes of agriculture and of agricultural production factors the framework is used to analyse barriers to the existence of the major intertemporal and factor markets it is applied specifically to land scarce environments for which it provides an internally consistent explanation for many of the well documented institutional features of such settings in addition the analysis provides new implications for among other phenomena the inter relationships among ownership holdings operational scale family size and factor productivity for the scarcity of animal rental markets and use of animals as collateral for the renting out of land by small landowners and for the existence of plantations for certain crops

is small beautiful farm size productivity and poverty in asian agriculture the debate on the relationship between farm size and productivity has gone through a complete circle in the 1960s it was perceived that small farms were efficient because they can fully use their resources particularly family labor and they can monitor their production activities closely but in the 1970s and 1980s as many asian countries rapidly moved towards industrialization and urbanization small farms were considered a major obstacle in this process

the inverse relationship between productivity and farm size a test using regional data from india the farm size productivity debate for india needs little introduction it has occupied a prominent position in the agricultural economics literature since 1962 when sen observed that indian farm management data revealed an inverse relationship between farm size and yields per acre since then no fewer than twenty journal papers have appeared on this subject sen 1975 the objective of this paper is to test two hypotheses that were either not given enough attention or left unresolved in the debate the first is that the inverse relationship is valid for all of indian agriculture it is not merely a phenomenon observed in a few sample villages this means a test of the hypothesis that the small farm sector as a whole is more productive than the large farm sector in indian agriculture the second hypothesis is that the inverse relationship is true only of a traditional agriculture and that it breaks down with technical progress a methodology is developed below which uses cross sectional regional data to test the two hypotheses simultaneously on applying this methodology to indian district level data 272 districts for 1970 71 it is found that the hypothesis of the small farm sector being more productive than the large farm sector cannot be rejected at low levels of agricultural technology but can be rejected at higher levels this suggests that the inverse relationship between yields and farm size although valid for a traditional agriculture cannot be assumed to exist in an agriculture experiencing technical change

explaining agricultural and agrarian policies in developing countries the paper describes and as far as possible explains variations in policies programs and institutions that influence agricultural growth agrarian relations and rural welfare across developing countries and over time it evaluates the impact of distorted policy patterns on agricultural production and rural poverty and identifies conditions under which policy reforms meant to bring about greater efficiency and equity are likely to be initiated and sustained it draws upon a broad range of literature to show how material conditions missing markets and government policies affect static welfare outcomes patterns of accumulation state formation and the establishment of political institutions it suggests ways to improve policy advice and proposes directions for future research

equilibrium credit rationing of small farm agriculture it is often argued that externally imposed contractual restrictions lead to inequitable credit rationing this paper argues that unrestricted laissez faire markets may also inequitably ration credit a formal model which grants borrowers autonomy in credit application and use demonstrates that adverse incentive and selection effects may cause banks to endogenously impose interest rate restrictions and ration small farms out of the credit market consequently liberalization of financial markets may be insufficient to guarantee small farms access to credit

new perspectives on farm size and productivity abstract the farm size and productivity debate has been limited by the focus on land or labor productivity generally showing respective productivity advantages to smaller or larger sized farms our purpose is to provide new perspectives on the debate by bringing together evidence from a set of novel case studies in both rich and poor countries common to them are the adoption of total factor productivity tfp as the comparative performance measure and the reliance on panels of farm micro data the present article presents a synthesis of findings from five case studies in i malawi tanzania and uganda ii bangladesh iii brazil iv australia and v the united states the preponderance of evidence from these studies suggests that there is no single economically optimal agrarian structure rather it appears to evolve with the stage of economic development certain farm sizes face relative productivity advantages such as small farms in africa but with economic and market growth that smallholder advantage will likely attenuate moving toward constant and eventually increasing returns to size yet importantly small farms may be quite dynamic and need not be a drag on agricultural growth until perhaps well into the development process

rural market imperfections and the farm size productivity relationship evidence from pakistan the subject of this article is the relationships between farm size and productivity and between farm size and profitability in the developing countries the recent controversies over the inverse size output relationship are reviewed and a framework is provided that explains the inverse relationship based on plausible assumptions about imperfections in the markets for labor land credit and risk from this framework a set of testable hypotheses are derived the hypotheses are tested on recent farm level panel data from pakistan a strong inverse relationship between farm size and yield is present in the sample even when household fixed effects are used to account for unobserved heterogeneity moreover the suggested market imperfections framework is consistent with the data

financial market efficiency in an agrarian economy microeconometric analysis of the pakistani punjab the shadow price of capital in production is a useful indicator of the efficacy of the rural financial system using data on participants and non participants in a small farm credit programme from the pakistani punjab this article estimates the shadow price of capital endogenous switching regressions techniques are employed to control for the likely heterogeneity of borrowers versus non borrowers results indicate that an individual selected at random from the population of small farmers would experience a 200 per cent rate of return on the first rupee borrowed from the small farm credit programme indicating a high shadow price of capital and a prima facie case for small farm credit programmes

can unobserved land quality explain the inverse productivity relationship abstract an inverse relationship between both farm productivity and labor intensity and farm size is a common empirical finding in developing country agriculture the traditional explanation has been imperfect labor markets recently it has been suggested instead that the inverse relationship is a statistical artifact resulting from omitted land quality using a farm level data set from java i investigate whether omitted variable bias can explain the inverse relationship i show that the inverse relationship and accompanying wage responses are inconsistent with a model of neoclassical farm behavior that ignores omitted variable bias instrumental variables techniques yield parameter estimates in which the inverse relationship is eliminated and the estimated wage elasticities are more in line with economic theory further econometric investigation hints that a model of omitted land quality may be a possible source of the inverse relationship these results emphasize the importance of considering the sources of cross sectional variation in estimating microeconomic relationships
