the female male unemployment rate differential the authors show that bottlenecks in the economy s ability to absorb new entrants do not explain the female male unemployment rate differential in canada the loose attachment of women to the work force explains only one quarter of the differential of overriding importance is the minimum wage if not for minimum wages mature women would have an unemployment rate below that of men relative minimum wages have been falling since 1974 further falls could lead to a negative female male unemployment rate differential and reverse all the standard arguments about a greater female labor force share increasing the natural rate of unemployment

women s access to credit does it matter for household efficiency studies that assess the impact of credit constraints on farm households efficiency have largely used the household as the unit of analysis this can be problematic when there are gender based market imperfections and asymmetries in how rights resources and responsibilities are distributed within the household constraints on women matter in addition to the efficiency loss associated with the husbands credit constraints when women are unable to meet their needs for capital their households experienced an additional 11 drop in efficiency this suggests that there are efficiency based arguments for enhancing women s access to capital and that studies based only on the household s head may significantly underestimate the true economic impact of credit constraints copyright 2008 oxford university press

profit function approximations and duality applications to agriculture monte carlo simulations of profit functions indicate that flexible functional forms may be ranked nearly the same with respect to allen uzawa partial substitution elasticities or price and fixed factor elasticities flexible functional form approximations of output price elasticities are generally worse than approximations of input price or fixed factor elasticities minflex laurent functional forms did not appear to approximate underlying elasticities any better than did their translog and generalized leontief counterparts

malawi s agricultural development a success story abstract at a time when attention was focused on africa s poor agricultural performance malawi demonstrated a capacity not only to feed itself but to produce a surplus for export during the periods covered in this paper its agricultural growth exceeded that of most african countries and compared favorably with success stories on the continent this research focuses on malawi s recent performance with particular attention on trends in the provision of essential agro support services credit extension and farmer training and input supply and marketing trends in these services are examined first at the national level and then at the district level while overall trends indicate substantial progress district level data reveal extensive unevenness moreover at the farm level census data on farmer training and technology utilization show fewer benefits to female operators and smaller farmers important elements of developmentally oriented infrastructure and services have been put in place and are functioning better than in most african countries this is important in terms of longer term agricultural development prospects there is ample evidence however that malawi s progress has not spread across different segments of the farm population or agriculture development districts both the unevenness and overall progress have been heavily influenced by donor support

food insecurity poverty and the malawian starter pack fresh start or false start abstract chronic food insecurity and chronic poverty are closely related in malawi since independence in 1964 national food security has been a key policy objective however until the 1990s less emphasis was placed on the household dimensions of food security and its links with chronic poverty in the last decade a number of initiatives have been used in malawi to tackle the issue of household food insecurity one of the most controversial has been the starter pack programme launched in 1998 initially consisting of a free handout of packs of improved maize seed legumes and fertiliser to every small holder farm household in malawi the scheme under donor pressure was subsequently scaled down to become a form of targeted social safety net programme this paper analyses the strengths and weakness of both the original programme and its scaled down version and assesses the reason for the considerable opposition to the programme from malawi s donor community although starter pack is no longer operative in malawi the malawian experience is used to derive lessons for other countries where household food insecurity is an important dimension of chronic poverty

farm household production efficiency evidence from the gambia this article investigates the economic efficiency of farm households with an application to the gambia the efficiency analysis is conducted not at the farm level but at the household level thus capturing the importance of off farm activities output based measures of technical allocative and scale efficiency are generated using nonparametric measurements an econometric analysis of factors affecting the efficiency indexes is then conducted using a tobit model technical efficiency is fairly high indicating that access to technology is not a severe constraint for most farm households the cost of scale inefficiency is modest allocative inefficiency by contrast is found to be important for the majority of farm households on the basis of the tobit results imperfections in markets for financial capital and nonfarm employment contribute to significant allocative inefficiency

voting and nonvoting a multi election perspective prior attempts to differentiate between voters and nonvoters have focused on a single election the implicit assumption being that voting or not voting in a particular election is indicative of a more general proclivity this paper tests the impact of a number of factors that have emerged in earlier studies as predictors ofvoting participation but uses participation over a series of 10 elections as the criterion the model tested here demonstrates greater explanatory power than those previously tested and follow up analysis strongly suggests that this explanatory power is a function of the multi election measurement of participation

a survey of agricultural household models recent findings and policy implications semicommercial farms that produce multiple crops make up a large part of the agricultural sector in developing economies these farms or agricultural households combine two fundamental units of microeconomic analysis the household and the firm traditional economic theory has dealt with these units seperately but in developing economies in which peasant farms dominate their interdependence is of crucial importance researchers have developed models of agricultural households that combine producer and consumer behavior in a theoretically consistent fashion recent empirical applications of these models have extended them and expanded the range of policy issues which can be investigated using this general framework this article reports the results of empirical applications of this model in india indonesia japan the republic of korea malaysia nigeria senegal sierra leone taiwan and thailand it provides a comparative analysis of the policy implications of the approach for such matters as the welfare of farm households the size of marketed surplus the demand for nonagricultural goods and services and for hired labor and the availability of budget revenues and foreign exchange

farm level fertilizer demand in java a meta production function approach this paper models seed variety choice and the demand for variable inputs as jointly determined by profit maximizing cultivators the approach parallels that of hayami and ruttan who postulated that changes in the output fertilizer price ratio induce movements along a meta fertilizer response function the envelope of individual variety specific response surfaces ignoring the possibility of seed variety switching leads to underestimates of fertilizer demand elasticities in addition estimation with samples reflecting a single seed variety may involve serious selection bias a two stage procedure which adjusts for selectivity bias is used to estimate the model with farm level data from java

cash crop liberalization and poverty alleviation in africa evidence from malawi this article uses the case of burley tobacco liberalization in malawi to investigate the efficacy of cash crop liberalization as an instrument for poverty alleviation in sub saharan africa the principal justification for cash crop liberalization is that markets allow farm households to increase their incomes by producing that which provides the highest return to their productive resources and use the cash to buy consumption goods using a latent welfare model we find that households that selected to grow cash crops had higher incomes than those that did not grow cash crops however we also find that due to the lumpiness and seasonality of cash crop incomes higher household incomes while increasing food purchases did not significantly affect per capita food intake irrespective of participation in cash crops for much of the cropping season rural households seem to rely more on nonfarm income for expenditure and consumption smoothing

substitution between unemployment insurance and workers compensation abstract this paper extends the literature on post injury duration of absence from work by developing a model that incorporates substitution between unemployment insurance benefits and workers compensation a theoretical analysis is presented in which the worker maximizes expected utility over four possible states of nature the model is tested empirically using pooled cross section and time series data at the two digit industry level the main findings support the predictions of the model an increase in workers compensation benefits increases the average duration of accidents with an elasticity of 0 9 1 4 while an increase in unemployment insurance payments reduces the average duration of accidents with an elasticity of 0 5 0 7

the nonvoting voter in voting research postelection surveys consistently overestimate voter turnout by a substantial margin this paper compares via discriminant analysis of data from the 1978 national election study the characteristics of respondents who falsely claim to have voted with the characteristics of actual voters and admitted nonvoters more importantly it undertakes two parallel analyses of the factors affecting voting or nonvoting the first employs respondent supplied voting data and the second employs officially validated voting data even though misreporters differ in some respects from actual voters and admitted nonvoters the parallel analyses in the latter part of the paper indicate that substantive conclusions about the factors that influence voting or nonvoting are largely unaffected by the use of validated as opposed to reported voting data

theories of share tenancy a critical survey for the past 2 decades the problems of agricultural tenancy have attracted a great deal of attention not only from agricultural economists but also from economists in general as a typical example of agencyprincipal contract relations despite the prolific growth of literature both theoretical and empirical there has been little convergence in opinions on tenancy contracts the divergence has been especially great on the understanding of the causes and the effects of sharecropping tenancy much confusion underlying the widely divergent perspectives has stemmed from partial treatments of contractual choice which unduly limit the optimizing behavior of contracting parties and the options of contract forms this essay aims at clarifying the sources of the confusion by reviewing the past literature in light of the more general theory of agency principal relations the agency theory in order to examine the problems of various theoretical models in a unified framework in section ii we first develop the basic framework of a general model of tenancy contract in section iii we clarify in terms of the general model contradictions latent in the traditional marshallian theory which asserts that share tenancy is inefficient because of the disincentive effect of cropsharing on the tenant s work effort in section iv we attempt to show that recent efforts to reconstruct the theory based on the traditional assumption have not yet been quite successful section v draws implications and testable hypotheses from more general theories incorporating the aspects of risk and uncertainty section vi tests allocational and distributional implications of those alternative hypotheses based on the summary of evidence col

relative efficiency of cotton farms in sudanese irrigated agriculture abstract in this paper the lau yotopoulos profit function model is applied to data from the sudan with the objective of investigating the relative technical price and economic efficiency of different groups of cotton farms in the irrigated agricultural sub sector the findings of the paper lend no support to the marshallian based efficiency argument recently utilized by the sudanese government to abolish the joint account system in favor of the land water charge system in all irrigated schemes the findings also establish the economic efficiency superiority of farms under medium staple cotton relative to those under long staple cotton however the hypothesis of absolute price efficiency perfect profit maximization was rejected for all groups of cotton farms the latter result has a bearing on the familiar hypothesis that farmers in the less developed countries are efficient but poor

economic efficiency and supply response of women as farm managers comparative evidence from western kenya summary this paper assessed the relative economic efficiency and output supply and input demand responses of women farmers in western kenya the results showed that women are as technically and allocatively efficient as men however neither men nor women have absolute allocative efficiency women farmers are equally responsive to price incentives in terms of output supply and input demand while education and extension contact have significant effects on overall maize supply and input demand only extension contact has significant effects among women farmers the paper discusses a number of significant results and concludes with implications for policy

does human capital raise farm or nonfarm earning more new insight from a rural pakistan household panel this study explores how human capital affects farm household earnings using two tools to refine measurement of human capital effects first it employs a two sector model to allow the allocation of family labor between farm and nonfarm activities second it accounts for village fixed effects to evaluate whether results from panel data differ meaningfully from a cross sectional data analysis with local binary variables the results show that education has a negligible effect on farm earnings instead experience appears to be the principal channel by which human capital affects agricultural performance in a traditional rural setting our results also suggest that prior models that fail to separate nonfarm activities spuriously exaggerated the effect of education to the farm sector in addition typical cross sectional analyses that ignore fixed effects may cause the effects of education on rural household earnings to be significantly overstated the fact that panel data regressions accounting for village level fixed effects found only one instance of education raising earnings the effect of literacy on nonfarm income suggests that considerable heterogeneity may have been ignored in cross sectional data analyses especially ones that omitted village level effects

rent seeking and the development of large scale agriculture in kenya south africa and zimbabwe in this article we examine the historical evidence on large farm efficiency rent seeking and the potential for increases in agricultural productivity through policy reform and land redistribution for kenya south africa and zimbabwe these countries have been chosen because all of them were or still are characterized by a very unequal distribution of land they also recently had to address and face the problem of resettlement kenya has successfully redistributed part of the farmland previously occupied by europeans zimbabwe since its independence in 1980 is executing an ongoing program of resettlement demands for land reform are currently gaining momentum in south africa the theory of production relations suggests that with low levels of mechanization large farms in general are less efficient than small farms due to the problem of labor supervision this theoretical argument is supported by a large amount of empirical evidence from latin america and asia the relative scarcity of empirical evidence from africa leads to the question of the reasons underlying the apparent success of large farm cultivation in southern and eastern africa we will argue that in the countries selected rent seeking by european large farm lobbies with the aim of reducing systematically the profitability of african small farm cultivation or equivalently the reservation utility of african farmers in the labor market was a major factor in making farming based on large operational holdings economically feasible the resulting policy distortions led to the decrease of small farm cultivators profits reducing the profitability of investment in human and physical capital in the smallholder sector as well as reducing the capital available for investment thus policy distortions

modeling fertilizer externalities around palo verde national park costa rica irrigated rice farming in costa rica involves use of agrochemicals that pollute important wetlands ecosystems such as the palo verde national park in the northeastern province of guanacaste we characterize rice farming in this region apply duality theory to estimate conditional factor demand for fertilizer and then simulate the impacts of alternative policies on fertilizer use using a normalized profit function we also estimate policy impacts on farmer profits as expected prices of rice seeds and fertilizer significantly affect use of fertilizer price incentives or taxes could encourage farming practices that reduce the threat to downstream ecosystems

rural income and poverty in a time of radical change in malawi abstract malawi is one of the poorest countries in africa there is widespread though not universal agreement about the shape of poverty in the country and the policy challenge this sets agriculture continues to be the most obvious means to stimulate broad based rural growth and to provide levels of food security and income needed for the majority rural population a longitudinal study over a decade during which radical policy and political changes occurred provides the data and basis for discussing the appropriate policy directions for reducing poverty

education experience and allocative efficiency a dual approach a generalization of the dual non frontier profit function approach to evaluating allocative efficiency is developed that allows for training human capital variables to influence the efficiency level directly an application to pennsylvania dairy indicates that education and experience are substitutes and play a significant role in the level of efficiency while these operators are not allocating their variable inputs in an absolutely efficient manner relative efficiency can be achieved for four of six possible input combinations for prescribed levels of education and experience furthermore the estimates of the efficiency measures suggest that these operators are maximizing production rather than short run profits

the effectiveness of structural adjustment lending initial evidence from malawi abstract the world bank s new programs of structural adjustment lending are likely to prove most effective with those governments which demonstrate shared ideals in their approach to economic adjustment and policy reform malawi has long been regarded as a country placing great reliance on the market in resource allocation showing restraint in public sector expansion and retaining a strong export orientation the balance of payments difficulties and the deterioration in economic circumstances which began in 1980 did not arise solely from external shocks but the structural adjustment lending programs introduced in 1981 as a means of easing the painful reform process found root in a fertile and responsive policy environment this paper chronicles the first two sals to malawi reviewing in particular the specific policy reforms advocated and required by the bank the extent of their implementation and the provisional effects on the malawi economy

profit supply and factor demand functions comment in lau and yotopoulos 1972 a new method of estimating production relations was developed building on lau and yotopoulos 1971 this method bringing together estimates of profit and factor demand functions was further developed in yotopoulos and lau to incorporate a test of rationality their method has since been applied by yotopoulos lau and lin sidhu sidhu and baanante 1979 1981 jamison and lau and junankar 1980a b 1982 because the assumption of rationality is so fundamental to economics and because few tests of this hypothesis exist the lau yotopoulos method is very important however these studies rest on advanced economic theory and sophisticated econometrics so it is easy to be intimidated by them sophisticated estimators however are not necessarily free from er

modelling the impact of world bank policy based lending the case of malawi s agricultural sector this article uses a multi market agricultural pricing model to analyse the impact of the world bank s three structural adjustment loans sals to malawi on the smallholder agricultural sector three price policy scenarios are simulated on the model representing zero partial and full compliance with the bank s sal price policy conditionality these scenarios are analysed in terms of their impact on the government budget smallholder real incomes maize production exportable cash crop production and the balance of payments critiques of the bank s programme and the government and bank bargaining strategies are assessed in the light of the modelling results

food marketing and pricing policy in eastern and southern africa a survey abstract this article surveys the empirical record of grain marketing and pricing policy in eastern and southern africa over 1930 1995 the paper addresses five key issues with major implications for food policy throughout africa a why the anticipated supply response to market liberalization has not yet occurred b why the common assumption of state taxation of farmers to support a cheap food policy does not apply in most of the countries in the region c why the temporary successes of the state led approach to stimulating smallholder grain production were unsustainable d why the elimination of government food subsidies associated with market reform has not adversely affected consumers and e why the fiscal cost of the marketing systems at least initially worsened rather than improved after the reforms were implemented in most countries the key future challenges for marketing policy are how to develop coordinated and financially sustainable input finance and commodity marketing systems for raising productivity growth in smallholder agriculture while overcoming inherited agricultural dualism and how to mitigate the effects of food price instability in a cost effective manner

how to define and study farmers management capacity theory and use in agricultural economics textbooks and articles on farm management stress the importance of the management capacity of the farmer with respect to his farm results however explicit definitions together with an elaboration of this concept are hard to find in this article aspects of management capacity are grouped into 1 personal aspects consisting of farmer s drives and motivations farmer s abilities and capabilities and his biographical facts such as age and education and 2 aspects of the decision making process consisting of practices and procedures with respect to planning implementation and control of decisions at the farm empirical studies on the role of management capacity in relation to farm results are reviewed frontier production functions are widely used in recent literature to estimate technical and economic efficiency of farms however in explaining differences in efficiency most studies do not go further than adding a biographical variable e g level of education this study concludes that a next step would be to include aspects of the decision making process longitudinal on farm observations which give possibilities for studying the dynamic aspects of the decision making are suggested to further analyze the concept of management capacity

the impact of agricultural liberalisation on food security in malawi abstract the donor supported structural adjustment programmes have not impacted favourably on livelihoods food security and the general welfare of the poor in malawi this resulted from the prescription of wrong policy packages and limited attention to poverty alleviation policies policies have tended to concentrate on promoting market and price mechanisms less on addressing production constraints and non economic barriers to broad based economic growth there are losers and winners as a result of policy reforms in agricultural produce marketing the losers are mainly the smallholder farmers in the category of net food buyers low income or wage earners in urban and semi urban areas and smallholder farmers in remote areas the winners are smallholder farmers in the category of net food sellers private traders institutional traders and the state marketing agency the paper analyses the impact of pricing policy and market deregulation on the state marketing organisation and on the private marketing system highlighting the lessons to be learned and making recommendations on how to improve the food security situation at the household level

explaining voter turnout patterns an information theory voting research is rich in empirical regularities yet a parsimonious theory of voter turnout that can match the facts has proven to be elusive this paper argues that voter turnout patterns can be explained by extending the traditional rational voter model to include limited information a model is presented in which utility maximizing consumers receive higher payoffs from voting the more confident they are of their vote choice the model provides an explanation for the most important cross sectional voter turnout patterns in addition it suggests a novel explanation for the post 1960 decline in u s participation

misconceptions and political outcomes a large literature shows that strategic interactions among actors with conflicting objectives can cause the political process to produce outcomes that lower welfare this paper investigates an alternative explanation of such outcomes if individuals errors in assessing the likely effects of proposed policies are correlated democratic decisionmaking can produce welfare reducing outcomes even in the absence of conflicting objectives under plausible assumptions choosing candidates from among the best informed individuals does not remedy the problems created by such errors but subsidising information and exposing representatives to information after their election do concentration of power has ambiguous effects

technical efficiency in developing country agriculture a meta analysis abstract a meta analysis is performed to review empirical estimates of technical efficiency te in developing country agriculture the objective of the study is to contribute to a better understanding of the factors that influence estimates of mean te a data set of 51 observations of te from 32 studies is used in order to test if specific characteristics of the data and econometric specifications account for systematic differences in the efficiency estimates results using the two limit tobit procedure indicate that factors such as primal versus dual number of fixed inputs and number of variable inputs increase average te estimates on the other hand using the cobb douglas functional form and cross sectional data yields a lower level of te other factors including the number of variables in the model crop type stochastic versus deterministic frontiers and sample size do not seem to significantly affect estimates of te across studies

a model of an agricultural household in a multi crop economy the case of korea it is the purpose of this paper to describe one method of extending the empirical applicability of the theory of the farm household to multi crop economies by integrating the econometric and linear programming models already available in the literature section i introduces the subject in section ii the theoretical model is presented in section iii korean data are used to assess the quantitative significance of the approach by calculating and comparing household response to changes in input and output prices for two different specifications of the models first the household is analyzed from the consumption side on the assumption that farm profits are exogenous this corresponds to the standard approach in consumer demand theory and second results are presented for a model in which consumption and production responses are integrated in a theoretically consistent fashion and farm profits are allowed to reflect production responses to price changes the results from this and other studies that use an integrated approach to production and consumption decisions highlight the need to change perceptions concerning agricultural household response to economic incentives in developing countries and to revise the design of economic projects and policies accordingly

how natural is canada s high unemployment rate abstract a reduced form price equation for canada 1956 1984 yields a stable estimate of 4 9 percent for the natural unemployment rate of men aged 25 and over with strong evidence against hysteresis once structural influences are accounted for the resulting profile for the aggregate natural unemployment rate rises smoothly from 5 5 percent in 1961 to a maximum of 8 0 percent in 1977 1978 and then declines rapidly to 6 4 percent in 1985 calculations based on an estimated production structure for the aggregate non energy sector of canada provide additional evidence against the excess real wage hypothesis and for the view that the recent fluctuations in canada s unemployment rate are mostly of the keynesian variety

u turns and full circles two decades of agricultural reform in malawi 1981 2000 abstract this paper traces the evolution of malawi s agricultural policy over the past two decades during this period the world bank has played a key role in shaping policy reform through its adjustment loans three distinct reform phases can be identified 1981 87 when policy was dominated by the dogmatism of the world bank s pricist and state minimalist policies 1988 94 when a more flexible position was taken by both the bank and the malawi government both of whom acknowledged the structuralist critique of earlier policies and 1994 to the present when the reform process in agriculture became more politicized and a schism developed between the bank and the government this latter period is used to illustrate some of the unresolved policy issues pertaining to similar low income agrarian economies

the effects of education in agriculture evidence from nepal the impact of education in modernizing and traditional agricultures of nepal is investigated by utilizing a production function framework education is found to have higher payoff to productivity in a modernizing environment than in traditional agriculture higher college education has a significant role in a modernizing environment but not in the traditional area while both worker and allocative effects of education contribute positively to agricultural production allocative effect surpasses worker effect in both environments however only the input allocation component of the allocative effect is important in traditional areas while both input allocation and input selection components are crucial in a modernizing agriculture

estimating farm level input demand and wheat supply in the indian punjab using a translog profit function application of the translog profit function to farm level data from punjab india allowed a more disaggregated analysis of the farm production structure compared to the case of cobb douglas formulation the flexibility afforded by translog formulation permitted measurement of the different impacts that exogenous variables have within and across input demand and output supply functions policy relevant elasticity estimates with respect to variable inputs and output prices fixed inputs a few soil related state of nature variables measured by soil analysis and education which are usually considered constraints to farm production were obtained and two examples of policy applications were developed

deriving natural rates of unemployment for sub national regions the case of canadian provinces in order to pursue informed stabilization policies it is vital for policy markers to have estimates of how much of the total unemployment rate can be classified as cyclical rather than natural unemployment this paper describes a method for generating regional natural rate estimates and applies this method to the case of canadian provinces results indicate that unemployment insurance generosity and relative minimum wages play an important role in determining natural unemployment rates in canadian provinces one of the enduring characteristics of the canadian labour market has been substantial and peresistent unemployment rate disparities across provinces the results of this study indicate that these disparities are primarily explained by differences in provincial values of structural variables such as unemployment generosity and by differences in provincial sensitivities to these structural variables a furher result is that variation in cyclical unemployment rates is substantially less in the traditio

land tenure and agricultural productivity in africa a comparative analysis of the economics literature and recent policy strategies and reforms summary this paper examines the convergence and divergence of results from economic studies of the relationships between land tenure security and agricultural productivity in africa and how these results have been incorporated into recent agricultural poverty alleviation and land policy documents the paper finds that there are both areas of convergence and divergence in the economics literature similarly the attention given to land tenure and its perceived effects on productivity varies considerably in the policy literature the significant heterogeneity in findings itself suggests that policy responses must pay attention to local context and the overarching macro and sectoral conditions within which tenure systems operate

structural change in malawi since independence consequences of a development strategy based on large scale agriculture abstract this paper investigates the nature of the structural change which has occured in the malawian economy since independence and identifies key policies pursued by the government which it is argued have been decisive in shaping this development the salient feature of structural change is shown to be the rapid growth of large scale agriculture associated with an equally rapid transfer of labour into wage employment and a decline in the importance of peasant production the implications of these changes for living standards and future development and policy are considered

the privatization of agricultural trading in malawi abstract this paper examines the privatization of smallholder agricultural output marketing in malawi despite problems with implementing the privatization program including serious disruptions in the supply of maize the staple food the move toward greater private sector involvement in agricultural marketing has been successful nonetheless several medium term development issues e g food security and buyer and seller of last resort functions need to be addressed in the context of relations between the marketing parastatal admarc and the private sector before the policy change can be regarded as fully successful

robust error specification in a production system economists estimating demand and supply systems face the question of using shares or quantities as dependent variables this article finds that inconsistent estimates are obtained if one makes the wrong choice a robust structure is presented to let the data choose the preferred form empirical applications to u s and texas agriculture using the generalized method of moments suggest that shares and quantities are rejected in favor of a more general functional form the texas application provides some evidence for fixed capital but not for labor copyright 2013 oxford university press

bilateral free trade agreements and customs unions the impact of the eu republic of south africa free trade agreement on botswana the eu has indicated that after 2008 its trade relationships with developing countries will be dominated by the development of preferential trade agreements although not a consequence of the cotonou agreement the free trade agreement between the eu and the republic of south africa eu rsa fta is clearly one of the first fruits of this approach to trade relationships however there is no evidence that the design of the eu rsa fta incorporated a comprehensive general equilibrium evaluation of the agreement for either the signatories or the other southern african nations the analyses reported here indicate that while the eu rsa fta may substantially benefit the signatories there are appreciable negative impacts for other states especially the rsa s immediate neighbours moreover the reluctance of the eu to fully liberalise trade in food and agriculture commodities results in a major reduction in the benefits for the rsa without ameliorating substantively the adverse implications for other nations

a natural experiment for identifying the impact of natural trade barriers on exports abstract the paper investigates the relative importance of trade policy and natural sources of export taxation in malawi a landlocked african economy these sources of export taxation are in turn used to explore how export supply would respond to trade liberalisation as opposed to measures which lower other international trade costs the findings indicate that trade policy barriers are now only a limited source of true export taxation and that trade policy reform needs to be complemented with reforms to reduce international trade including transport costs

modern technology and economic efficiency of philippine rice farmers farmer s recent study and frankel s review of griffin s book suggest that belief in a gap between actual and potential agricultural production in developing countries has regained currency in the development community timmer s concern with measuring technical efficiency and the attempts of shapiro and miiller to relate modernization and information to technical efficiency focus on differences in productivity among farmers as indicators of such a gap 2 among technologists the gap hypothesis has a number of faithful adherents including the former director of the international rice research institute irri who could not understand why the asian farmer who had adopted the new rice varieties was not doing better somehow he felt that the rice scientists who had obtained yields of 5 to 10 metric tons per hectare on the irri farm still could not explain why so many filipino farmers for example obtained on the average less than one metric ton per hectare increase in yield after shifting from the traditional to the high yielding varieties 3 in response to these persistent questions in 1974 scientists at irri began a research project to measure the yield gap and to understand the factors responsible for it the yield gap was defined by biologists as the difference under farmers conditions between the maximum yield possible

the origins of agricultural policy in ivory coast 1960 86 there is a more limited degree of urban bias in cote d ivoire than in most other african countries different explanations for relatively high producer price shares reliable extension services etc are required for the periods 1960 70 and 1970 86 the arguments offered focus on the composition of the income portfolios of senior political elites and on the rise of special kinds of urban informal associations that have acted as lobbying organisations on behalf of rural household members the article seeks to dispel the notion that differences in opportunities for political participation alone can account for the variations in the outcomes observed in the african cases

credit program participation and child schooling in rural malawi summary we evaluate the impact of agricultural credit program participation on children s school attendance in rural malawi our paired site sampling survey reveals that credit uptake decreased school attendance by young girl children this finding raises concerns that young girl children are exploited as child labor either at home or in the field when working adults become more involved in income generating activities financed by credit the data however do not show clear evidence for young girls staying at home to do household chores or working in the fields in households that obtained credit but instead find simultaneous occurrence between attending school and taking responsibilities for domestic chores by young children it would appear therefore that credit uptake delays the realization of this concurrence among young girl children and leads to delayed school enrollment

estimating substitution and expansion effects using a profit function framework this study reports a first attempt to derive all the relevant information with respect to the structure of production of an industry using knowledge of only a profit function using estimates of a profit function for canadian agriculture a procedure to separate substitution and expansion effects for both inputs and outputs was implemented information concerning net input and output substitution and complementarity possibilities were obtained the most important empirical results suggest that the hypothesis of nonjoint production of crop and animal outputs in canadian agriculture cannot be rejected and that hired and operator labor are complements rather than substitutes

is a turnaround in africa possible without helping african women to farm a turnaround in africa is not possible in the short run of at least 1 decade without helping women farmers with hand hoes gain equal access to basic agricultural inputs and resources this is so because women are such active participants in farming it is estimated that for 82 countries women constitute 46 of the agricultural labor force in sub saharan africa and 31 of the force in north africa and the middle east in the long run however a turnaround is possible without helping women to farm because women farmers will be displaced as agricultural intensification occurs but because the intensification process will be extremely uneven both within and between african countries the displacement of women farmers will also be uneven thus their displacement will be blocked or slowed down in regions with sufficient land resources and land extensive family systems extensive male out migration lack of control of animal diseases or the presence of gender neutral incentives to produce in conclusion women farmers in these regions will still be the norm while those in other regions will be displaced as intensification required by a turnaround proceeds to insure that women farmers are not displaced policy planners at international national and local levels should communicate with technical experts and extension specialists about the need to incorporate women as agricultural producers with full access to yield increasing inputs in development projects

the structure of u s agricultural technology 1910 78 this paper utilizes 1910 78 time series data and a single product aggregate translog profit function to measure the structure of u s agricultural technology duality relations are used to devise a multifactor measure of biased technical change a measure of nonhomotheticity is introduced which indicates the effects scale change has had on aggregate cost shares the empirical analysis finds that different nonhomothetic technologies characterized the prewar and postwar periods differing technical change biases are consistent with relative price trends during the two periods showing that the long run structure of u s agricultural technology has been consistent with the hayami ruttan induced innovation theory

smallholder technical efficiency controlling for environmental production conditions abstract smallholder agricultural production depends heavily on environmental production conditions that are largely exogenously determined yet few data sets collect necessary detailed information on environmental production conditions this oversight raises the spectre of likely omitted variables bias because farmers input choices typically respond in part to environmental conditions moreover because environmental production conditions are rarely symmetrically distributed the omission also generally leads to upward bias in estimated technical inefficiency and to biased estimates of the correlates of estimated technical inefficiency as well using panel data from 464 traditional rice plots in cote d ivoire we show that controlling for heterogeneous environmental production conditions significantly changes inferences perhaps especially with respect to smallholder rice farmers estimated technical inefficiency

is unemployment insurance addictive evidence from the benefit durations of repeat users the author finds evidence that the past occurrence of a spell of insured unemployment lengthens the duration of future spells descriptive statistics from canadian administrative data covering mid 1971 to early 1990 suggest that unemployment insurance ui claimants tend to spend a longer and longer time collecting benefits with each additional claim they make this finding contradicts the implication of static neoclassical models that successive ui spells should be of the same length the author hypothesizes that the stigma attached to receiving unemployment benefits erodes with each new ui claim an individual files

agricultural incentives in developing countries measuring the effect of sectoral and economywide policies the impact of sector specific direct and economywide indirect policies on agricultural incentives for 18 developing countries for the period 1975 84 are estimated the direct effect is measured by the proportional difference between the producer price and the border price adjusting for distribution storage transport and other marketing costs the indirect effect has two components 1 the impact of the unsustainable portion of the current account deficit and of industrial protection policies on the real exchange rate and thus on the price of agricultural commodities relative to nonagricultural nontradables and 2 the impact of industrial protection policies on the relative price of agricultural commodities to that of nonagricultural tradable goods the authors found that a in almost all cases the direct effect is equivalent to a tax on exportable goods and to a subsidy for importables b the indirect effect also taxes agriculture and dominates the direct effect and c the direct policies for both importables and exportables stabilize domestic producer prices

pricing policies in africa with special reference to agricultural development in malawi abstract microeconomic policy in the controlled market economy of malawi rests upon three fundamental balances these are the food export balance the rural urban income linkage and the domestic donor contribution to development capital there are therefore six major domestic polarities food and exports rural and urban domestic and donor within the microeconomic system any change in one will necessitate changes in the other five or the triplex becomes unbalanced this is the rigidity in the capacity of small economies to adjust

relative efficiency of women as farm managers profit function analysis in cote d ivoire abstract the efficiency of women farmers in the agricultural sector of developing countries is passionately debated very few studies have examined this issue in african agriculture all previous studies were based on production functions but have been criticised as suffering from simultaneous equation bias because the input levels are endogenous the profit function method avoids these problems no previous study has used the profit function method to test for technical allocative and economic efficiency differences between women and men farmers the objective of this paper was to determine whether women rice farmers are less efficient than men rice farmers in cote d ivoire using the restricted normalised profit function method our results show that the relative degree of efficiency of women is similar to that of men the paper provides empirical support for efforts to eliminate bias against women farmers in african agriculture

the response of peasant farmers to price incentives the use and misuse of profit functions recent famines in chad ethiopia and the sudan have highlighted a major problem facing less developed countries how does an ldc become self sufficient in food production the answers to this question range from the narrowly defined economic one or economistic approach to the more widely based institutional reforms approach the former approach typified by say schultz 1964 or the world bank 1982 would emphasise the importance of mainly price incentives the latter approach as typified by myrdal 1968 in his monumental work asian drama would emphasise the importance of land reforms as a pre condition for agricultural development the debate has sometimes followed a misleading path and discussed whether peasants are rational or whether they are lazy inert tradition bound etc the aim of this article is to show that the use of profit functions to model peasant behaviour in ldcs is seriously flawed neo classical economic theory within which profit functions are embodied ignores the historical social institutional and political context within which peasant farmers operate peasant farmers do not operate in full blooded capitalist impersonal competitive input and output markets the article is structured as follows section ii outlines the profit function approach and section iii provides a survey and critique of applications of the profit function to ldc agriculture section iv concludes with some general remarks on analysing peasant behaviour in an alternative paradigm

adjustment with a fixed exchange rate cameroon cote d ivoire and senegal as members of the cfa franc zone cameroom cote d ivoire and senegal cannot use the nominal exchange rate as a tool of macroeconomic adjustment this article considers these countries responses to the commodity and oil price shocks of the 1970s in light of this and other institutional constraints using a two sector model it shows that there exist instruments that in principle permit the real exchange rate depreciation necessary for adjusting to macroeconomic imbalances the authors interpret the very different adjustment experiences of the three countries despite their common economic structure and institutional setting in terms of different uses of these instruments alternative assumptions about the labour market leave the qualitative nature of the results unaltered statistical analysis of data from the three countries confirms the model s linking of the current account and real exchange rate with the instruments of adjustment

why kill the golden goose a political economy model of export taxation why do governments tax exports at rates that are ultimately self defeating an answer may lie in the time inconsistent nature of a low tax policy using a dynamic model of export taxation i show that the sustainability of a low tax policy depends on three variables the ratio of sunk costs to total costs how heavily future export revenue is discounted and expected future export earnings using data on taxation leadership duration and profitability i test this theory for 32 countries and six crops from sub saharan africa these three variables are statistically and economically relevant predictors of tax regime

population tenure and natural resource management the case of customary land area in malawi abstract this paper analyzes the factors determining conversion of woodlands to agricultural land changes in tree cover and maize yield for the last two and a half decades by using aerial photos and field survey data in 57 communities in malawi the econometric analysis revealed that population pressure led to greater land conversion but had no effect on yield or tree cover changes areas where greater changes in traditional tenure systems have occurred are associated with reduction in tree cover and expansion of agricultural land these results suggest the importance of strengthening institutions to manage natural resources

environmental impacts of technological change in bangladesh agriculture farmers perceptions determinants and effects on resource allocation decisions this article measures the impact of modern technology adoption in raising farmers environmental awareness and the impact of farmers environmental awareness on resource use by utilizing survey data from 21 villages in three agro ecological regions of bangladesh the econometric analysis is based on the application of the tobit model explaining farmers environmental awareness in the first stage and a profit function examining environmental awareness and resource use relationships in the second stage results reveal that the level and duration of involvement with modern technology raises farmers environmental awareness and that farmers environmental awareness reduces resource use including chemicals farmers who are aware of the adverse environmental impacts of modern agricultural technology use lower amounts of all inputs in order to avoid further environmental damage therefore efforts to raise farmers environmental awareness are expected to enhance intangible benefits accruing from a relatively less chemical intensive environment

green gold burley tobacco smallholder agriculture and poverty alleviation in malawi abstract the abolition in 1990 of the estate monopoly on cultivation of burley tobacco is expected to play an important role in reducing poverty among smallholders in malawi a nationwide survey in 1993 shows that smallholder households cultivating burley also grow more hybrid maize use more fertilizer and are more food secure but resource poor households particularly those headed by women face land and labor constraints on burley adoption burley and hybrid maize increase the demand for hired labor but not enough to absorb the growth in the rural labor force broad based poverty alleviation requires technology and programs targeted at the majority of smallholders with holdings of 0 5 hectares or less

farm size relative efficiency and agrarian policy in cote d ivoire profit function analysis of rice farms abstract this paper examines the relative economic efficiency of small and large rice farms in cote d ivoire using a profit function approach no differences in the relative economic efficiency of small and large farms were found this conclusion is robust under alternative model specifications agrarian reforms directed towards further concentration of landholding for large farms in cote d ivoire cannot be justified based on economic efficiency results show that access to credit and use of modern rice varieties significantly increase profits to improve technical efficiency of rice farms an accelerated program to provide information credit improved seeds and other inputs is needed when all the farms i e large and small are taken together there is evidence of allocative inefficiency strategies are needed to remove such management related inefficiencies in rice production either through the development of a better market price information system or effective farmer oriented technical training programs by rice extension workers

on the use and misuse of profit functions for measuring the price responsiveness of peasant farmers a comment the standard profit function approach has been applied successfully in a number of ldcs to measure the price responsiveness of peasant farmers yet various problems afflict this approach including but not restricted to the existence of non competitive market structures zero valued observations exclusion of relevant variables lack of participation in output and or input markets and endogeneity of input and or output prices the impact of these problems on estimation results however can be minimised through modifications and adaptations of the standard approach better specification of the underlying technology and the use of selected functional forms
