tenure security and land related investment evidence from ethiopia the authors use a large data set from ethiopia that differentiates tenure security and transferability to explore determinants of different types of land related investment and its possible impact on productivity while they find some support for endogeneity of investment in trees this is not the case for terraces transfer rights are unambiguously investment enhancing the large productivity effect of terracing implies that even where households undertake investments to increase their tenure security this may not be socially efficient in ethiopia government action to increase tenure security and transferability of land rights can significantly enhance rural investment and productivity

rural nonfarm activities and agricultural crop production in nigeria although most rural households are involved in the farm sector the nonfarm sector has grown significantly in recent decades and its role in rural development has become increasingly important this article examines the effect of participation in nonfarm activities on crop expenses of farm households in nigeria the relationship is modeled using a nonseparable agricultural household model that suggests that participating in nonfarm activities can relax the credit constraints facing farm households and reduce risk thereby helping households improve farm production and smooth consumption over time the results show that participation in nonfarm activities by nigerian farmers has a positive and significant effect on crop expenses and in particular on payments for hired labor and inorganic fertilizers separate analysis of the six geopolitical zones in nigeria indicates that it is in the south south and south east zones where nonfarm participation appears to induce more hiring of labor the results support the hypothesis that nonfarm participation helps relax liquidity constraints but suggests how that liquidity is used is zone specific in general the results also indicate that liquidity is used more to pay for inputs into staple production as opposed to cash crops

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

land allocation in hyv adoption models an investigation of alternative explanations microeconomic theory provides four competing explanations for partial land allocation to new and traditional seed varieties in hyv adoption decisions input fixity portfolio selection safety first behavior and learning testing a general model that contains each as a special case suggests that they are jointly most likely to explain land allocation in the hyv adoption decisions of malawian smallholders yet when each explanation is tested to the exclusion of the others as is usually the case in the literature competing hypotheses are individually significant results suggest that employing approaches based on single explanations may lead to inappropriately narrow conclusions

credit constraints and agricultural productivity evidence from rural rwanda while potentially negative impacts of credit constraints on economic development have long been discussed conceptually empirical evidence for africa remains limited we use a direct elicitation approach on a national sample of rwandan rural households to empirically assess the extent and nature of credit rationing in the semi formal sector and its impact using an endogenous switching model elimination of all constraints could increase output by some 17 per cent implications for policy and research are spelled out

macro economic determinants of antidumping a comparative analysis of developed and developing countries abstract this study examines how macro factors influence the use of antidumping in developed and developing countries a panel data analysis of 99 countries over 1980 2000 reinforces the view that the primary jurisdiction for the antidumping law is really more political than economic furthermore it suggests that once the wto is fully enforced the use of antidumping will spread among developing countries not only due to greater liberalization pressures but also as many countries would like to create an antidumping ability so as to counter its use against them this may reverse the trade gains that liberalization may ensure to them this paper thus calls for the granting of the special and differential treatment to developing countries in this provision finally based on its findings the paper argues that future negotiations should be directed toward revising safeguard rules and replacing antidumping by this new clause

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

agricultural change rural labor markets and forest clearing an illustrative case from the philippines this paper studies the links between agricultural employment and upland activities at a tropical forest margin a model of lowland agricultural production is combined with a model of labor allocation on a representative upland farm to show how labor productivity agricultural wages and the returns from upland activities determine rates of forest clearing farm level data from the philippines demonstrate how agricultural intensification in the form of lowland irrigation development led to an increase in labor demand an increase in employment of upland inhabitants and small but statistically signi ficant reductions in rates of forest clearing

land inheritance and market transactions in uganda studies on the role of nonmarket land transactions remain limited this paper addresses two questions is land inheritance driven by underdeveloped land markets how does land inheritance influence land disposal and acquisition we use a switching regression model on household data from rural uganda we find that the initially landless or near landless households due to little or no land inheritance obtain land through land markets while those that are land rich dispose of land through land sales and bequests the results suggest that a process of land equalization is unfolding within the sample

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

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

spending on children direct survey evidence we present estimates of spending on children from a danish expenditure survey which asks respondents directly about allocations of expenditures to individual household members our main finding is that the average danish family allocates 44 of total assignable spending on non food non durables and services to children there is considerable variation across households more is spent on older children and expenditure on children is an increasing concave function of the number of equivalent children we find that households in which the mother has had a child by a previous partner spend 24 less on children than otherwise similar households

meso economic filters along the policy chain understanding the links between policy reforms and rural poverty in latin america abstract the paper clarifies the meso economy concept by defining it as comprising both the market mechanisms and administrative procedures through which policy decisions and market signals trickle down to the household level three main bodies of literature are reviewed the policy oriented literature in which the meso economy was initially considered the transaction cost approach analyzing market and policy failures and the micro economy level of agricultural household models the paper develops a synthesis of macro meso and micro economic perspectives which focuses on the roles played by three levels of filters intervening along the policy chain implications for policy and research are drawn

farm productivity in rwanda effects of farm size erosion and soil conservation investments this paper examines the effects of farm size soil erosion and soil conservation investments on land and labor productivity and allocative efficiency in rwanda there were several key results first there is a strong inverse relationship between farm size and land productivity and the opposite for labor productivity for smaller farms there is evidence of allocative inefficiency in use of land and labor probably due to factor market access constraints second farms with greater investment in soil conservation have much better land productivity than average those with very eroded soils do much worse than average smaller farms are not more eroded than larger farms but have twice the soil conservation investments third land productivity benefits substantially from perennial cash crops and the gains to shifting to cash crops are highest for those with low erosion and high use of fertilizer and organic matter program and policy effort to encourage and enable farmers to make soil conservation investments to use fertilizer and organic matter and to participate in cash cropping of perennials will have big payoffs in productivity land markets that allow smaller farmers to buy land could also increase aggregate productivity

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

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

investment and abandonment behavior of rural households an empirical investigation this article uses models of irreversible investment under uncertainty to examine the investment and abandonment behavior of poor rural households it considers the decision of ugandan coffee farming households to invest in or abandon coffee trees the observed levels of investment and abandonment are found to be consistent with models of investment that allow for irreversibility uncertainty fixed costs and liquidity constraints the findings highlight the importance of addressing volatility irreversibility fixed costs and liquidity constraints in order to increase households responsiveness to changes in the fundamentals and to enable households to recover from shocks to their capital stock

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

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
