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

nonconvexities in the production of timber biodiversity and carbon sequestration abstract fixed logging costs and administrative constraints on logging regulations can create nonconvexities in forestry production sets that include timber and nontimber products managing forests to produce multiple values at a landscape level through the aggregation of stands that are completely or partially specialized in the production of timber or nontimber products can consequently be superior to management systems that treat all stands uniformly even when all stands are identical both fixed costs and administrative constraints are empirically important sources of nonconvexity in tropical rainforests the former is more important when the nontimber product is carbon sequestration while the latter is more important when the nontimber product is biodiversity protection uniform management appears to be superior for the joint production of timber and carbon sequestration while specialized management might often be superior for the joint production of timber and biodiversity at least at low discount rates

learning about a new technology pineapple in ghana this paper investigates the role of social learning in the diffusion of a new agri cultural technology in ghana we use unique data on farmers communication patterns to define each individual s information neighborhood conditional on many potentially confounding variables we find evidence that farmers adjust their inputs to align with those of their information neighbors who were surpris ingly successful in previous periods the relationship of these input adjustments to experience further indicates the presence of social learning in addition applying the same method to input choices for another crop of known technol ogy correctly indicates an absence of social learning effects jel d83 013 033 q16

adaptive versus rational expectations and the fisher effect substantial controversy remains over the causes of interest rate fluctuations this controversy frequently focuses on the role of expected inflation the theoretical determinats of the nominal rate are examined usig the is lm as model and it is shown that the augmented fisher equation is sensitive to the expectations generating mechanism the model assumes that the nominal rate ceteris paribuschanges one for one with expected inflation the total impact however may take any value from zero to one the empirical analysis sequentially estimates reduced form equations based on adaptive and rational expectations the results confirm prior findings that nominal rates do not adjust one for one with inflation the results also yield some insight on the applicability of the assumption of rational versus adaptive expectations

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

land rental development via institutional innovation in rural jiangsu china previous studies have demonstrated that there are two important preconditions for encouraging land rental in agriculture out migration and the enhancement of security and transferability of land rights focusing on the latter we scrutinize the impacts of institutions aimed at facilitating land use dynamism particularly the rural shareholding cooperatives rscs which have been established recently at the local level in rural china in general we find that rscs can pave the way for the extension of property rights to farmland and promote more efficient land use patterns using survey data collected from 300 village committees in rural jiangsu province we estimate the effectiveness of rscs in encouraging land rental our analysis reveals that rscs can serve as intermediate agents for reducing transaction costs associated with exchange of land use rights and thereby not only encourage land rental consolidation activities but also enable the entry of non farm household entities into the farm business

agricultural technology productivity and poverty in madagascar summary this paper uses a unique spatially explicit dataset to study the link between agricultural performance and rural poverty in madagascar we show that controlling for geographical and physical characteristics communes that have higher rates of adoption of improved agricultural technologies and consequently higher crop yields enjoy lower food prices higher real wages for unskilled workers and better welfare indicators the empirical evidence strongly favors support for improved agricultural production as an important part of any strategy to reduce the high poverty and food insecurity rates currently prevalent in rural madagascar

differentiated contracts heterogeneous borrowers and the mortgage choice decisions previous analyses of mortgage choice assume that adjustable rate mortagages are standard contracts and estimate bivariate models the authors estimate a multinomial logit model that explicitly treats mortgages as differentiated contracts and provides insights on several important issues the impact of price variables differs significantly across alternative mortgage contracts borrower heterogeneity particularly mobility influences the type of contract chosen and borrowers respond to market conditions as expected when choosing between alternative mortgage contracts copyright 1995 by ohio state university press

the effect of land tenure governance on technical efficiency evidence from three provinces in eastern china this study aims to identify the mechanisms through which land tenure governance affects the technical efficiency of grain production in an integrated framework and to examine the impacts of the public governance village self governance and relational governance of land tenure on the technical efficiency of contracted land and rented in land farm level survey data collected from liaoning jiangxi and jiangsu provinces covering the years of 2014 and 2015 is used for the empirical analysis the findings indicate that i public governance associated with land certification significantly increases the technical efficiency of grain production ii village self governance and administrative land reallocations can serve as substitutes for the land rental market in optimizing the distribution of land resources and improving technical efficiency and iii compared to multi year transfer contracts both annual and open ended transfer contracts have negative impacts on technical efficiency

analysis of environmental efficiency variation in this article we develop and implement a methodology for analyzing the sources of variation in environmental efficiency across producers we formulate a two stage model in the first stage we use stochastic frontier analysis to estimate both technical and environmental efficiency in the second stage we again use stochastic frontier analysis to regress estimated environmental efficiency scores against a variety of technology physical environment and management variables in this stage we estimate the impact of each explanatory variable on environmental efficiency and we derive conditional estimates of environmental efficiency from the one sided error component we illustrate our methodology with an empirical application to a panel of dutch dairy farms we find evidence of relatively low levels of environmental efficiency and we find that environmental efficiency can be improved through a number of policy options including the provision of farmers with more insight into the nutrient balance of their farms

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

do overlapping property rights reduce agricultural investment evidence from uganda the need for land related investment to ensure sustainable land management and increase productivity of land use is widely recognized however there is little rigorous evidence on the effects of property rights for increasing agricultural productivity and contributing toward poverty reduction in africa whether and by how much overlapping property rights reduce investment incentives and the scope for policies to counter such disincentives are thus important policy issues using information on parcels under ownership and usufruct by the same household from a nationally representative survey in uganda the authors find significant disincentives associated with overlapping property rights on short and long term investments the paper combines this result with information on crop productivity to obtain a rough estimate of the magnitudes involved the authors make suggestions on ways to eliminate such inefficiencies

the ban on indexed bonds 1933 77 in a recent article in this review nissan liviatan and david levhari attempt to explain the phenomenon that in spite of recent marked inflationary trends the important capital markets have not developed a significant free private enterprise market for cost of living linked bonds p 366 they note that the familiar theoretical complete dominance of indexed bonds over nonindexed bonds holds unambiguously only in an economy in which there are no nominal assets they demonstrate that borrowers may in theory insist on hedging the inflation risk on their nonindexed cash balances by issuing some nonindexed bonds at a discount that makes them attractive in spite of the risk they impose on lenders their model leads them to conclude that indexed bonds might not completely dominate nonindexed bonds however they do not claim that their model explains the phenomenon they set out to explain why is it that the free market to use their expression has come up with virtually no indexed bonds at all fortunately a simple explanation for the nonexistence of indexed bonds in the united states was provided two years

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

governance and timber harvests resource economics theory implies that risks associated with weak governance have an ambiguous impact on extraction with the net impact depending on the relative strengths of depletion and investment effects previous empirical studies have found that improved governance tends to reduce deforestation but to raise oil production here we present evidence that the marginal impact of improved governance on timber harvests in developing countries during 1984 2006 was nonmonotonic it tended to raise harvests in countries with weaker governance but to reduce harvests in countries with stronger governance this nonmonotonic impact occurred for both an index of governmental integrity corruption bureaucracy quality law and order and an index of governmental stability a simulation of hypothetical increases in these governance indices to the maximum 2006 values observed in the sample predicted that improved governance would reduce harvests in most countries but could raise harvests in some with large increases occurring in countries with the weakest governance

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

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

inverse productivity land quality labor markets and measurement error abstract this paper examines the role that land quality and imperfect markets play in generating the inverse productivity relationship in the international crop research institute for the semi arid tropics icrisat data differences in land quality largely explain the inverse productivity ip relationship in the random effects profit regression but not in labor demand regressions controlling for labor and land market failures and differences in soil quality eliminates the ip relationship for male labor but not female labor in the random effects estimates the inverse relationship is much stronger in fixed effects than random effects estimates suggesting that the farm size variable may be subject to measurement error a view supported by the results of instrumental variables estimation

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

comparing features of convenient estimators for binary choice models with endogenous regressors abstract we discuss the relative advantages and disadvantages of four types of convenient estimators of binary choice models when regressors may be endogenous or mismeasured or when errors are likely to be heteroscedastic for example such models arise when treatment is not randomly assigned and outcomes are binary the estimators we compare are the two stage least squares linear probability model maximum likelihood estimation control function estimators and special regressor methods we specifically focus on models and associated estimators that are easy to implement also for calculating choice probabilities and regressor marginal effects we propose the average index function aif which unlike the average structural function asf is always easy to estimate

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

endogeneity of risk perceptions in averting behavior models this paper examines the relationship between averting expenditures choices and perceived health risks models in the literature often employ risk perceptions as explanatory variables without addressing the potential endogeneity of the perceived risk we examine the implications of ignoring endogeneity in this context using an application to both drinking water choices and expenditures and perceived health risks our data are from an internet based cross canada survey that employs a novel interactive risk ladder to elicit mortality risk perceptions relating to water we employ two fundamentally different methods to assess the impact of risk perceptions on behavior an analysis of expenditures on alternate water sources and a model of proportional choice of water sources results suggest the presence of averting behavior with respect to perceived mortality risks and that the estimated effect of water risks is greater than 3 times higher when using approaches that correct for endogeneity compared to models that do not

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

impacts of land certification on tenure security investment and land market participation evidence from ethiopia this brief summarizes the results of a gender impact evaluation study entitled impacts of land certification on tenure security investment and land market participation evidence from ethiopia conducted between 2006 and 2011 in ethiopia the study observed the impact of land registration on tenure security land related investment and rental market participation using 900 randomly selected households and 4000 plots cultivated by the households on the household and land plots level certification resulted in significant reduction of tenure insecurity and an increase in land related investment the propensity to invest in water conservation increased between 20 and 30 percent from panel estimates the increased investment appears to be sustained over the long term the propensity to rent land increases by 9 to 13 percent the titling had significant positive impacts on the rate at which female headed households rented their land funding for the study derived from the gender action plan global land tools network and norwegian environmentally and socially sustainable development essd trust fund

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

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

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

the postwar stability of the fisher effect most research concerning the fisher relationship has concentrated on the magnitude and significance of the response of nominal interest rates to anticipated inflation recently attention has shifted to the stability of that response according to previous estimates the impact of anticipated inflation on interest rates varies substantially over time by extending a standard model to include tax and aggregate supply shock effects we are able to reduce such instability considerably our results also reveal that increased foreign demand for bonds lowers the interest rate

has government any role in money abstract recent interest in monetary reform has been sparked by the emergence of a world irredeemable paper money system in light of this interest we review the current validity of four good reasons friedman advanced in 1960 to rationalize government intervention we conclude that the forces that produced government involvement in the past will persist deregulation of financial intermediaries is desirable on grounds of market efficiency though it is an open question whether government should continue as lender of last resort we expect that the present world fiat money standard will neither degenerate into hyperinflation nor revert to a commodity standard

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

modern value chains and the organization of agrarian production empirical studies of agrarian production in developing countries often find that small farms possess a productivity advantage over larger farms eswaran and kotwal 1986 famously derive this inverse farm size productivity relationship from the structure of agrarian production the focal prediction of their model is that in otherwise equivalent economies a more egalitarian land distribution raises both output and producer welfare the traditional spot procurement system implicit in the eswaran and kotwal model however diverges fundamentally from modern contractual procurement practices we therefore develop a new model of agrarian production in order to determine whether the introduction of a modern value chain alters the welfare effects of land redistribution the inverse farm size productivity relationship persists in our model but we find that more egalitarian land distribution leads to nonmonotonic changes in producer welfare we also find that the introduction of a modern sector can harm the laboring classes

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

the missing fisher effect on nominal interest rates in the 1950s the response of nominal interest rates to price increases has been intensively studied since the onset of substantial inflation and historically high interest rates in the late 1960s early empirical investigations yohe and karnosky 1969 gibson 1972 and pyle 1972 tested the fisher hypothesis that nominal rates react one for one to changes in the expected inflation rate paralleling results in the wage price literature these studies often found that nominal rates appeared to adjust too little to imply neutrality with respect to expected inflation theoretical work by mundell 1963 and tobin 1965 that incorporated wealth effects by sargent 1972 that considered an extended macromodel and by darby 1975 and feldstein 1976 that allowed for income tax effects however suggested that additional variables like measures of fiscal and monetary policy may be relevant and that nominal rates may change by either more or less than unity in response to a one unit change in expected inflation two puzzling features of the response of nominal rates to expected inflation remain first even when other factors are included estimates of that response are unstable for the postwar period see cargill and meyer 1977 second empirical studies to date have failed to produce any statistically discernible impact of expected inflation on interest rates during the 1950s see cargill and meyer 1974 and cargill 1976 similarly striking is the sizeable residual autocorrelation exhibited by nearly all estimates that include the 1950s these symptoms of model misspecification imply that an important factor may have been omitted from previous models a reduced form model of nominal interest rates that allows for an additional impact that of factor supply shocks is advanced in section ii the empirical tests in section iii show that once this variable is included a significant relation between interest rates and expected inflation emerges for the 1950s we also show that our specification is stable over the entire post accord period section iv concludes

housing credit access model the case for lithuania abstract the research described in this paper aimed at achieving two major goals first to identify and describe rational credit access development in advanced industrial economies as well as providing recommendations for lithuania the multiple criteria quantitative and conceptual analysis of rational credit access in developed countries and in lithuania allowed for the identification of areas where the lithuania situation is comparable partly comparable or quite different from levels attained by advanced industrial economies the data of this quantitative and conceptual analysis was used to identify rational credit access development trends in western europe and the usa as well as providing some recommendations for lithuania the determination and realization of efficient housing credit access in lithuania would create better conditions for the functioning of the housing system second the paper contains a description of a suggested method in choosing efficient housing investment instruments and lenders the quantitative and conceptual databases that are being developed at present give an exhaustive description of housing investment instruments and allow for their multiple criteria analysis this helps to determine efficient investment instruments for the countries in question the databases and multiple criteria analysis offered could also be used in searching for efficient lenders the methods suggested in this paper can also be applied to solving similar problems in other countries

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

choosing between fixed and adjustable rate mortgages note introduction in recent years mortgage borrowers have been given a wide variety of financing methods from which to choose e g guttentag 1983 barnett and mckenzie 1984 examples include assumptions adjustable rates shared appreciation growing equity and numerous others by far the dominant two have been the standard fixed rate and the adjustable rate mortgage beginning with regulation changes in 1979 adjustable rate mortgage lending at first was fairly restricted but with the major deregulation change in 1981 the types of adjustable rate mortgages have proliferated 2 now lenders have the flexibility to use numerous indexes including inflation and disposable income indexes make interest rate changes independent of payment changes and allow negative amortization the purpose of this paper is to examine the choice between fixed and adjustable rate mortgages 3 two views have dominated the theoretical literature one that emphasizes the irrelevance of borrower characteristics in the mortgage choice decision given the prices and terms of the contract and one that focuses on the potential impact of borrower characteristics assuming asymmetric information 4 this paper is the first to examine empirically the impact of pricing and borrower characteristics on the choice of mortgage contract

participation in rural land rental markets in sub saharan africa who benefits and by how much evidence from malawi and zambia we use nationally representative household level panel survey data in two neighboring countries in southern africa zambia and malawi to characterize the current status of rural land rental market participation by smallholder farmers and their subsequent welfare impacts rural rental market participation is much higher in densely populated malawi than in lower density zambia reflecting the role of land scarcity in driving rental market development consistent with previous literature we find evidence that rental markets contribute to efficiency gains within the smallholder sector by facilitating the transfer of land from less able to more able producers on average in both countries furthermore we find that rental markets serve to re allocate land from relatively land rich to land poor households we examine the impacts of participation on a number of welfare outcomes and find evidence for generally positive returns to renting in land in both countries on average however our analysis also indicates that the returns to renting in land vary strongly with scale of production tenants who produce more have larger returns to renting in and many of the smaller producers who rent in do so at an economic loss the impacts of renting out i e participating in markets as landlords are decidedly more mixed with overall negative returns to landlords in malawi and negligible returns to landlords in zambia the findings in this article highlight the need for researchers and policymakers in sub saharan africa to stay attuned to how land rental market participation and its impacts evolve in the near future

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

a tax induced clientele for index linked corporate bonds this paper analyzes the circumstances under which tax considerations favor or disfavor the use of index linked corporate bonds using a model similar to miller s investors choices of assets depend on their tax preferences for interest income versus capital gains and their preferences for the timing of returns it is concluded that the absence of indexlinked bonds in the u s cannot be attributed solely to tax reasons however following the 1986 tax reform act the tax code is expected to disfavor the use of index linked bonds the absence of index linked i l bonds in the u s is puzzling index linked bonds are common in countries that have experienced persistently high and or volatile rates of inflation both the periodic interest payments and the principal of an i l bond are linked to a price index this design provides protection against inflation induced changes in the nominal interest rate and prevents erosion of the bond s real value during inflationary periods anticipated or unanticipated the theoretical literature on i l bonds has focused primarily on the risk reduction aspect see for example sarnat 9 fischer 3 and siegel and warner 11 the recurrent theme of these studies is that the introduction of i l bonds reduces inflationary risks to both debtors and creditors these studies argue that in a portfolio context i l bonds provide investors protection against a risk that cannot be fully hedged otherwise fischer 4 conjectured that a possible reason for the absence of i l bonds in the u s may be the tax treatment of the returns on these bonds 2 from a tax point of view i l bonds differ from nominal bonds bonds hereafter in two respects first the returns on i l bonds consist of a combination of interest income and capital gains whereas the returns on nominal bonds consist in a steady state of interest income only second while the compensation for the inflation induced erosion in the real value of the principal of a nominal bond is part of the periodic interest payments and hence is taxed every period the corresponding compensation on an i l bond is realized and taxed only when the bond is sold thus holding i l bonds allows a tax deferment that is not possible when nominal bonds are held

interest rates and expected inflation 1831 1914 a rational expectations approach irving fisher argued that interest rates contain a premium for expected inflation and assembled a mass of data both historical and statistical in nature to support his argument 5 6 7 as a research paradigm his argument has proven useful in explaining the behavior of interest rates during the post war period however his original empirical analysis was never persuasive and contemporary studies using modern statistical techniques fail to find the fisher effect in the data fisher used this article examines yet one more time the behavior of interest rates and inflation during basically the 19th century this study is different from other contemporary studies in four important ways first a consumer price index as is required by fisher s theory and not a wholesale price index is used to measure inflation second expected inflation is modeled using a rational expectations approach expected inflation is not simply proxied by a weighted average of past inflation third the fisher effect is included in a reduced form model with other determinants of interest rates the fisher effect is therefore tested

land tenure security and investment incentives puzzling evidence from burkina faso abstract the commonsense logic associating higher land security and higher incentives to invest has been recently called into question in the case of african agriculture to be meaningful empirical tests have to be carefully designed so as to take account of the possible endogeneity of the land rights variable this is done in this paper by applying suitable econometric methods to the original data collected in burkina faso the results obtained cast doubt on the existence of a systematic influence of land tenure security on investment by reviewing the justifications for scepticism in the recent literature we are able to conclude that the traditional village order where it exists provides the basic land rights required to stimulate small scale investment

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

land tenure differences and investment in land improvement measures theoretical and empirical analyses this article develops a theoretical framework to examine the relationship between land tenure arrangements and households investment in soil improving and conservation measures it then analyzes this relationship with a multivariate probit model based on detailed plot level data from villages in the brong ahafo region of ghana a major hypothesis tested is that investment in productivity enhancing and conservation techniques are influenced by land tenure arrangements the theoretical analysis and empirical results generally reveal that land tenure differences significantly influence farmers decisions to invest in land improving and conservation measures the findings also show that tenure security does affect farm productivity

does it pay to participate in decision making survey evidence on land co management in jiangsu province china member participation in decision making is a critical part of resource co management however little is known about the welfare consequences of participation this paper analyzes the impact of cooperative member participation in decision making on their incomes using data from 364 members of china s land cooperative program we distinguish two levels of participation in decision making voting and obtaining financial information and use a bivariate probit model and propensity score matching to estimate their impact the results indicate that household head s age gender and education and family size wealth and political affiliation determine participation in decision making participation in either voting or obtaining financial information has a positive impact on cooperative members land income there is also a strong joint effect of voting and obtaining information with an increase in land income of 16 we conclude that broad participation can ensure more equitable access to land income for members

migration remittances and agricultural productivity in china in our paper we have used the new economics of labor migration framework to trace the complex linkages that exist among migration remittances and agricultural productivity in china constraints in the operation of on farm labor and capital or insurance markets or institutions provide households with a motivation to migrate and distort on farm operations when labor leaves in our household sample the net impact of migration and remittances on maize production is negative excerpt

the potential of land rental markets in the process of economic development evidence from china abstract we develop a model of land leasing with agents characterized by unobserved heterogeneity in ability and presence of an off farm labor market in this case decentralized land rental may contribute to equity and efficiency goals and may have several advantages over administrative reallocation the extent to which this is true empirically is explored using data from three of china s poorest provinces land rental markets and administrative reallocation reallocate land to those with lower endowments but the former are more effective in doing so and have a bigger productivity enhancing effect information on hypothetical market participation suggests that reducing transaction costs in land rental markets could help to realize significant additional productivity gains

african re agrarianization accumulation or pro poor agricultural growth recent signs of increasing agricultural production in a number of countries in sub saharan africa are by some commentators connected to local level differentiation this paper discusses such interpretations using household level longitudinal data from smallholder households in eight african countries for the period between 2002 and 2008 the use of a mixed methods social science approach complements traditional economic approaches through adding a spatial perspective pro poor agricultural growth so far is concentrated to particular villages where it is highly inclusive the policy challenge remains to devise strategies that can enhance growth also in marginal areas

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

royalty systems government revenues and forest condition an application from malaysia royalty structure has been linked to deforestation through non sustainable harvesting and high grading yet royalties are an important rent generation mechanism for governments in this paper a dynamic model of government policy choice is used to compare different royalty systems with respect to government revenue generation and high grading empirical analyses of the various royalty systems is then undertaken for forest concessions in malaysia one unique aspect of our study is an examination of how different royalty systems impact harvesting of highand low valued timber species government rent capture and concessionaire profits the results should help with future royalty design

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

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
