rationality of preliminary money stock estimates earlier studies have presented mixed evidence on the rationality of the federal reserve s preliminary money stock estimates the authors investigate the rationality of m1a m1 m2 and m3 for both seasonally and not seasonally adjusted data they find preliminary growth rates of these aggregates to be rational for not seasonally adjusted data but irrational when data are seasonally adjusted using monte carlo studies the authors conclude that irrationality in seasonally adjusted data arises from the specific seasonal adjustment procedure used by the federal reserve as a result researchers conducting similar tests may want to focus exclusively on not seasonally adjusted data copyright 1995 by mit press

smallholder market participation concepts and evidence from eastern and southern africa abstract this paper reviews the evidence on smallholder market participation with a focus on staple foodgrains i e cereals in eastern and southern africa in an effort to help better identify what interventions are most likely to break smallholders out of the semi subsistence poverty trap that appears to ensnare much of rural africa the conceptual and empirical evidence suggests that interventions aimed at facilitating smallholder organization at reducing the costs of intermarket commerce and perhaps especially at improving poorer households access to improved technologies and productive assets are central to stimulating smallholder market participation and escape from semi subsistence poverty traps macroeconomic and trade policy tools appear less useful in inducing market participation by poor smallholders in the region

the hyperinflation model of money demand revisited in this paper we propose a test of the hyperinflation model of money demand which is valid under any assumption concerning agents expectations subject only to the restriction that forecasting errors are stationary it is also demonstrated that highly efficient parameter estimates can be obtained and restrictions on them tested under the same weak assumption finally it is shown how these first stage estimates can be utilized to test the stronger assumption of rational expectations the arguments are illustrated by analysis of the classic data on european hyperinflations previously analyzed by cagan 1956 barro 1970 and abel dornbusch huizinga and marcus 1979 copyright 1991 by ohio state university press

optimal inflation tax under precommitment theory and evidence the authors develop and test the orthogonality conditions implied by a dynamic model of the inflation tax a distinguishing feature of the analysis is that the welfare loss from inflation the money demand function and the time path of inflation are jointly derived from first principles of government and private sector intertemporal optimization quarterly data for argentina brazil and israel are used in implementing the model although the overidentifying restrictions of the model are not rejected in most cases there are several data points characterized by higher rates of inflation than the optimal rates under precommitment copyright 1992 by american economic association

money demand and seigniorage maximizing inflation conventional estimates of the seigniorage maximizing inflation rate often make use of the cagan form which implies a constant semielasticity of money demand with respect to inflation this paper shows that the elasticity of substitution in transactions between money and bonds determines how the inflation semielasticity of money demand changes as inflation rises allowing for a variable semielasticity estimates of seigniorage maximizing inflation for a panel of eleven high inflation countries are lower than those obtained by using the cagan form estimates based on the correct measure of the opportunity cost of money also differ sharply from those obtained when using conventional inflation measures copyright 1995 by ohio state university press

the demand for money in developing countries assessing the role of financial innovation traditional specifications of money demand have commonly been plagued by persistent overprediction implausible parameter estimates and highly autocorrelated errors the authors argue that some of these problems stem from the failure to account for the impact of financial innovation they estimate money demand for ten developing countries using various proxies for financial innovations they also assess the relative importance of this variable finding financial innovation can be better modeled as a stochastic random walk trend rather than a deterministic time trend financial innovation plays an important role in determining fluctuations of the demand for money the importance of this role increases with the rate of inflation

what are the farm level impacts of malawi s farm input subsidy program a critical review this article provides a critical analysis of the current frontier of research evaluating malawi s farm input subsidy program fisp whose main objectives are increasing maize production promoting household food security and enhancing rural incomes we focus on farm level studies in malawi identifying consistent and contrasting research results in order to draw important policy lessons and provide suggested avenues for future research while national production estimates suggested dramatic increases in maize production and productivity during the years of the fisp the farm level studies found relatively modest increases in maize production and yields over the same period consistent with the farm level results of modest maize production increases there has been a relative increase in real maize prices and the country continued to import maize during most of the subsidy program years furthermore there is evidence that better off households gained substantially more than poorer households when they participated in the program together these findings cast some doubt on the fisp s ability to reduce food insecurity and poverty we propose a number of policy lessons and suggestions for rigorous investigation including research that directly measures the causal impacts of the fisp program on poverty in malawi

money supply announcements and interest rates another view in this paper i use a new approach to analyze the impact of money supply announcements on the bond market before 1980 the only available work on this subject consisted of a few unpublished papers by conrad 1978 sivesind 1978 and urich 1979 1 more recently published papers by grossman 1981 and urich and wachtel 1981 have appeared roley 1982 extends the grossman study to incorporate data after the federal reserve policy statement of october 6 1979 both grossman and urich and wachtel are primarily concerned with the question of money market efficiency using survey data made available by money market services of san francisco and data on treasury bill yields each finds that the market responds quickly to unanticipated changes in the money supply but that anticipated changes have no effect on interest rates in addition grossman finds that when he adds other variables such as past changes in the money

fertilizer subsidies and private market participation the case of kano state nigeria this article estimates the effect of a fertilizer voucher program on farmer participation in the private fertilizer market in nigeria using a double hurdle model to address corner solution challenges with estimating input demand and a control function approach to account for the endogeneity of subsidized fertilizer acquired the study finds evidence that receiving subsidized fertilizer in kano nigeria increased both the probability and extent of participation in the private fertilizer market findings demonstrate that under certain circumstances e g where input dealers links to farmer are weak there could be significant gains from the temporary use of voucher programs to strengthen such links

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

explaining smallholder maize marketing in southern and eastern africa the roles of market access technology and household resource endowments research on household food grain sales behavior in developing countries has tended to focus on the roles of market access and prices to explain why many rural households do not sell staple crops though recent literature suggests that low household asset endowments may also be key constraints we use econometric analysis of panel data from smallholders in kenya mozambique and zambia to inform the design of public investments that will enable smallholders to increase their maize sales results show that investments that raise farm level productivity and land access are an essential complement to investments that improve market access

monetary information and monetary neutrality abstract the monetary theory of business fluctuations in market clearing models constructed under the rational expectations assumption as advanced by lucas and others involves the idea that suppliers and demanders will typically misinterpret movements in the general level of prices as representing more or less favorable relative opportunities for real activities the present paper examines the consequences of agents possessing contemporaneous monetary information of a potentially noisy variety for the non neutrality of unanticipated monetary events within such an equilibrium business cycle model this modification of the information structure has the strong testable implication that real activity will be uncorrelated with contemporaneous monetary data

money demand and exchange rate determination under hyperinflation conceptual issues and evidence from yugoslavia a modified monetary model of exchange rate determination is advanced and tested for the yugoslav hyperinflation of 1992 94 stating that the exchange rate is determined directly in the money market thus implying that private agents due to dollarization denominate their real money holdings in foreign currency empirical evidence supports the advanced model apart from the last seven months of the yugoslav hyperinflation the exact re present value model of the exchange rate is accepted while that of the price level is rejected for the whole period of hyperinflation the modified money demand schedule with money holdings denominated in foreign currency is nonlinear with decreasing semielasticity of money demand

a policy agenda for pro poor agricultural growth abstract sub saharan africa and parts of south asia are likely to hold large numbers of very poor rural people into the foreseeable future although both history and theory suggest a pre eminent role for agricultural growth in poverty reduction in poor agrarian economies such growth today faces new difficulties many of these difficulties are endogenous to today s poor rural areas others result from broader processes of global change but some are due to changes in the dominant policy environment emphasizing liberalization and state withdrawal examination of 20th century green revolutions suggests that active state interventions were important in supporting critical stages of agricultural market development unfortunately such interventions benefits in institutional development are easily overlooked whereas their high costs are much more visible policy implications are discussed

cagan s paradox and money demand in hyperinflation revisited at daily frequency using daily data the cagan money demand is estimated and accepted for the most severe portion of serbia s 1992 1993 hyperinflation i e its last 6 months an implication is that the public adjusted daily throughout this extreme period moreover the obtained semi elasticity estimates are by far lower than those previously found using monthly data sets consequently the daily estimates reject the longstanding cagan s paradox based on monthly studies by showing that the economy has been on the correct increasing side of the laffer curve almost through the end of hyperinflation this strongly supports the view that hyperinflation is triggered and driven all way through its end by the government s hunt for non decreasing seigniorage daily adjustments of public in hyperinflation can account for the difference between the results obtained at daily and monthly frequencies calling into question the latter some evidence is offered that the findings of this paper may hold for other hyperinflations

data revisions are not well behaved we document the empirical properties of revisions to major macroeconomic variables in the united states our findings suggest that they do not satisfy simple desirable statistical properties in particular we find that these revisions do not have a zero mean which indicates that the initial announcements by statistical agencies are biased we also find that the revisions are quite large compared to the original variables and they are predictable using the information set at the time of the initial announcement which means that the initial announcements of statistical agencies are not rational forecasts

can agricultural input subsidies reduce the gender gap in modern maize adoption evidence from malawi abstract nationally representative data for malawi were used to measure the gender gap in adoption of modern maize and to investigate how if at all malawi s farm input subsidy program fisp has impacted the gap regression results show the probability of adopting modern maize was 12 lower for wives in male headed households and 11 lower for female household heads than for male farmers receipt of subsidized input coupons had no discernible effect on modern maize adoption for male farmers receiving a subsidy for both seed and fertilizer increased the probability of modern maize cultivation by 222 for female household heads suggesting the fisp has likely reduced the gender gap in adoption of modern maize in malawi

are preliminary announcements of the money stock rational forecasts abstract we develop a theoretical framework of analyzing preliminary announcements of economic data and then apply this framework to the money stock we find that preliminary announcements of the money stock are best characterized as measured with classical errors in variables that is the revision is not correlated with the true value of the series the revision is however forecastable using information available at the time of the preliminary announcement our ability to forecast the revision implies that preliminary announcements are not rational estimates of the true money stock

can we improve upon preliminary estimates of payroll employment growth we explore the feasibility of improving upon the preliminary estimates of payroll employment growth from the u s bureau of labor statistics by predicting subsequent revisions to these estimates using the preliminary estimates themselves and other information available concurrently results of statistical tests suggest that the preliminary estimates can be improved upon that is they are not efficient forecasts of the revised estimates the improvement of preliminary estimates as indicators of estimates of employment growth following annual benchmarks is particularly large the unanticipated component of the revision based on the annual benchmarks is reduced by more than 22

cointegration and cagan s model of hyperinflation under rational expectations when money and prices are integrated of order two philip cagan s 1956 model of hyperinflation will give rise to two different levels of cointegration in most of the literature on the german hyperinflation one of these cointegrating relationships has been ruled out a priori by assuming that velocity shocks follow a random walk using data from the german hyperinflation the author finds this assumption to be unjustified based on a straightforward extension of the cointegrated var approach suggested by john y campbell and robert j shiller 1987 a method to evaluate the cagan model under rational expectations and no bubbles is proposed and implemented to the german data copyright 1993 by ohio state university press

changing interest rate responses to money announcements 1977 1983 abstract this paper investigates when and how the response of interest rates to money announcements changed in recent years the response of both short and long rates rises in october 1979 but drops during 1981 during mid 1982 the response of long rates raises again but without a change in the response of short rates despite a number of ex post explanations for these shifts none of the major hypotheses of why interest rates respond to money announcements provides a complete ex ante explanation of these response shifts

peasant household behaviour with missing markets some paradoxes explained a model of peasant household behavior under varying degrees of household specific food and labor market failures is constructed to show that these structural features can explain several well known patterns of peasant response which have often been attributed to peculiar motives presumed specific to peasants the model explains sluggish response to cash crops prices and high instability in perceived food and labor scarcities the key role of manufactured consumer goods prices in stimulating peasants effort in cash crops production the effectiveness of taxation as opposed to incentives in stimulating cash crops production and the key role of technological change in food production to enhance cash crop production results are obtained analytically in the case of one market failure and by numerical simulation with more than one

agricultural growth and economic development a view through the globalization lens this article re visits the age old proposition that agriculture growth contributes to overall economic development and asks whether the relationship still holds in an increasingly globalized world there is overwhelming empirical support for the above proposition indeed it is hard to find exceptions barring a few city states where sustained economic development has not been preceded by robust agricultural growth however there are a large number of countries that have witnessed neither agricultural growth nor economic development even in countries where agricultural growth has been significant dramatic inter regional differences persist this article examines the factors that contribute to or constrain the process of agricultural transformation does the process of globalization and the resultant changes in agrifood systems offer new opportunities for agriculture led growth or will it further marginalize excluded countries regions and groups the factors that cause exclusion are examined both in terms of globalization forces and in terms of domestic shortcomings in policies and governance policy interventions that attempt to reduce the costs of transition to a globalized agricultural system are explored including safety nets for those left behind

subsidies and crowding out a double hurdle model of fertilizer demand in malawi this article uses a double hurdle model with panel data from malawi to investigate how fertilizer subsidies affect farmer demand for commercial fertilizer the article controls for potential endogeneity caused by the nonrandom targeting of fertilizer subsidy recipients results show that on average 1 additional kilogram of subsidized fertilizer crowds out 0 22 kg of commercial fertilizer but crowding out ranges from 0 18 among the poorest farmers to 0 30 among relatively nonpoor farmers this indicates that targeting fertilizer subsidies to the rural poor is likely to maximize the contribution of the subsidy program to total fertilizer use

principal challenges confronting smallholder agriculture in sub saharan africa summary this paper uses small scale farm survey data from five countries of eastern and southern africa to highlight four under appreciated issues i how land distribution patterns constrain the potential of crop technology and input intensification to enable many small farms to escape from poverty ii why most smallholders are unable to produce more than a marginal surplus or participate meaningfully in commodity markets iii why most farmers are directly hurt by higher grain prices and iv why the marketed agricultural surplus is exceedingly concentrated among a small group of relatively large smallholders policy and public investment options are reviewed in the light of these findings there is no one future for small farms in africa much depends on government policy and investment decisions

zambia s input subsidy programs over the last decade subsidies for fertilizer and hybrid maize seed have re emerged as a cornerstone of the government of the republic of zambia s grz s agricultural development and poverty reduction strategies this article reviews the farmer input support programme fisp and other grz input subsidy programs since structural adjustment it then synthesizes existing and presents new empirical evidence on the programs targeting outcomes and effects results suggest that although 73 of smallholder households cultivate less than 2 hectares of land and that these households constitute 78 of the smallholder farms below the us 1 25 capita day poverty line the majority 55 of fisp fertilizer goes to households that cultivate larger areas other factors constant wealthier households receive more subsidized inputs subsidized fertilizer promotes maize intensification and extensification at the expense of fallow land but an additional kg of subsidized fertilizer only raises maize output by 1 88 kg on average as a result of low maize fertilizer response rates poor targeting crowding out and diversion of fertilizer intended for the program financial benefit cost ratios for fisp fertilizer are well below one the article concludes with recommended reforms to fisp including that it be downsized and the savings invested in known drivers of pro poor agricultural growth

transactions costs and agricultural household supply response we develop and estimate a model of supply response when transactions costs create a situation where some producers buy others sell and others do not participate in markets we present two rationales for why producing households may have different relationships to the market proportional and fixed transactions costs using data on mexican corn producers we estimate an empirical model that allows for separate tests of the significance of both types of transactions costs revealing that both fixed and proportional transactions costs matter for the estimation the results provide consistent estimates of supply elasticity and measures of the relative importance of factors determining both proportional and fixed transactions costs

disrupting demand for commercial seed input subsidies in malawi and zambia summary this study uses nationally representative household level panel data from malawi and zambia to identify the determinants of subsidized maize seed and fertilizer receipt and to estimate how input subsidies affect households commercial purchases of improved maize seed varieties in both countries we find that households in areas where the ruling party won the last presidential election acquire significantly more subsidized inputs than other households results also indicate that each additional kilogram of subsidized maize seed acquired by a household reduces its commercial improved maize seed purchases by 0 58 kg in malawi and by 0 49 kg in zambia on average

the impact of farm input subsidies on maize marketing in malawi abstract this paper investigates the effects of subsidised fertilizer on marketing of maize in malawi it uses the nationally representative two wave integrated household panel survey ihps data of 2010 and 2013 the results suggest that subsidised fertilizer on average increases farmers maize market participation as sellers total quantity of maize sold and maize commercialisation in addition participation in subsidised fertilizer programme is found to increase the probability of farmers to be net sellers and increases net quantity of maize sold however the study finds no evidence of effect on net quantity of maize bought and on household maize self sufficiency these results suggest that the farm input subsidy programme has contributed toward an increased level of maize market supply engagement for small farmers and in this sense the policy has the potential to provide the wider external benefits furthermore the results have implication on the sustainability of the subsidy programme policy formulation and design of programmes for the agricultural sector and small farmers in developing countries

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

welfare effects of vegetable commercialization evidence from smallholder producers in kenya we investigate whether smallholder horticultural commercialization is able to as often stipulated reduce poverty in developing countries with the help of panel household survey data from kenya we find evidence for a positive association between vegetable commercialization and household welfare even when controlling for unobserved heterogeneity across households interestingly the effect differs depending on which market vegetables are being produced for commercialization through the export market is consistently positively associated with income but not wealth while there is some limited evidence for commercialization through the domestic market channel being positively related to welfare measured by asset holdings and income depending on the specification

fertilizer subsidies political influence and local food prices in sub saharan africa evidence from nigeria abstract the last decade has seen a resurgence in the use of fertilizer subsidies in sub saharan africa however there is limited empirical evidence on the effects of fertilizer subsidy programs on local food prices using an instrumental variables approach we explore the effect of a fertilizer subsidy program on the seasonal growth rates of grain prices in nigeria our results suggest that the fertilizer subsidy program had very small effects on the growth rates of grain prices between the post planting and post harvesting seasons we also find that political influence played a role in the distribution of subsidized fertilizer we discuss how the weak effects on the price growth rates may be caused by low market orientation output market structures greater focus on farmers incomes low marginal productivity of fertilizer and politically influenced targeting

money demand during hyperinflation and stabilization bulgaria 1991 2000 the demand for money in bulgaria is estimated over a ten year period 1991 2000 of high inflation and inflation uncertainty the paper distinguishes between three well defined sub periods high variable but not systematically accelerating inflation from 1991 until april 1996 the near hyperinflation period from may 1996 to february 1997 and the subsequent stabilization after the adoption of a currency board the empirical analysis utilizes a standard methodology of cointegration and error correction the functional determinants of the demand for money change during the different sub periods during the hyperinflation episode cagan s model is employed

tests of equilibrium macroeconomics using contemporaneous monetary data abstract this paper uses contemporaneous monetary data to carry out econometric tests of the equilibrium approach to modelling the relation between monetary disturbances and macroeconomic fluctuations the theoretical analysis introduces into an equilibrium macroeconomic model the availability of preliminary data on current monetary aggregates and the process of accumulation of revised monetary data the econometric analysis tests two hypothesis derived from this extended model one hypothesis concerns the neutrality of perceived monetary policy the econometric results imply rejection of this hypothesis the other hypothesis concerns the non neutrality of errors in preliminary monetary data the econometric results fail to reject the contrary of this hypothesis these tests provide strong evidence against the reality of the equilibrium approach

do input subsidy programs crowd in or crowd out commercial market development modeling fertilizer demand in a two channel marketing system many governments in developing countries distribute fertilizer at subsidized prices in an effort to stimulate small farmers agricultural productivity and food security prior fertilizer demand studies have largely failed to account for the effects of government programs on farmers commercial purchases using a double hurdle model and nationally representative rural household panel data in zambia we distinguish between these sources and measure the contemporaneous crowding in and crowding out effects of government input programs on commercial fertilizer sales where the private sector is relatively active and average wealth is higher areas seemingly more likely to be targeted by government programs results indicate that subsidies have substantially crowded out the private sector in some cases to the point that such programs could actually lower overall fertilizer use on the other hand in poorer areas where the private sector is relatively inactive subsidies help to generate demand and crowd in private sector retailers empirical studies explicitly modeling farmers fertilizer purchase behavior within a dual marketing framework can provide important insights for agricultural policy discussions in developing countries

the information content of weekly money supply announcements this paper analyzes the information content of weekly money supply announcements and the use of this information in the market determination of interest rates a short term rational expectations model of the financial market is constructed which incorporates the reaction of the federal reserve to deviations from target money supply and provides a context for analyzing the impact of announcements in the model the federal reserve attempts to maintain target growth rates in the money supply by compensating for past deviations from target announcements which contain an unanticipated movement in the money supply lead the public to expect that the federal reserve will change the rate of growth in the short run to compensate the revision of expectations about future short term money supply leads the public to revise their expectations about short term interest rates the implications of the model are empirically tested using data from a survey of expected changes in the money supply and u s treasury bill data the results support the implications of the model that is weekly money supply announcements do contain new information for the market determination of interest rates and it is only the unanticipated component of the announcement which is important

forecastable money growth revisions a closer look at the data the data for preliminary and revised u s money growth data are reexamined the findings contrast with those of the previous literature which has concluded that the data revisions behave like classical measurement errors this paper finds that the revisions are forecastable which contradicts the random measurement hypothesis as well as the efficient forecast hypothesis although ill behaved in this manner it is possible that the announcements represent observations rather than forecasts however the evidence suggests that they are a mixture of the two this finding offers a potential explanation for the failure of the data to show significant real effects of money growth revisions

a selectivity model of household food marketing behavior in sub saharan africa the agricultural household s discrete decision of whether to participate in coarse grain markets is separated here from the continuous decision of how much to sell or buy conditional on participation failure to participate in markets results from high fixed transactions costs a selectivity model endogenously switches households into alternative market participation states correcting for bias caused by the exclusion of unobservable variables affecting both discrete and continuous decisions improved market information increases the probability of participation by sellers while access to cereals processing technology increases quantities transacted by both sellers and buyers conditional on participation

misspecification versus bubbles in hyperinflation data comment abstract in this article i critically review some of the claims and analyses made by hooker j int money financ 19 2000 583 in his study of the cagan hyperinflation model i argue that i contrary to what hooker claims cointegration tests can be used to discriminate between bubbles and no bubbles ii contrary to hooker s claim his empirical results for the interwar european hyperinflations do not in general imply that the cagan model is misspecified iii although hooker s analyses build directly on the durlauf and hall bounds on the variances of specification errors in models with expectations nber working paper 2936 massachusetts cambridge 1989 methodology he neglects an important part of that methodology namely the measurement of the magnitude of noise i present such measures and together with reported cointegration tests the noise measures help reinterpreting hooker s empirical results

pitfalls in testing for explosive bubbles in asset prices a number of studies e g robert j shiller 1981 olivier j blanchard and mark watson 1982 kenneth d west 1988 have argued that dividend and stock price data are not consistent with the market fundamentals hypothesis in which prices are given by the present discounted values of expected dividends these results have often been construed as evidence for the existence of bubbles or fads related arguments have been made with respect to gold bonds and foreign exchange a major problem with such arguments e g james hamilton and charles whiteman 1985 is that apparent evidence for bubbles can be reinterpreted in terms of market fundamentals that are unobserved by the researcher behzad t diba and herschel i grossman 1984 1988b and hamilton and whiteman 1985 have recommended the alternative strategy of testing for rational bubbles by investigating the stationarity properties of asset prices and observable fundamentals 1 in essence the argument for equities is that if stock prices are not more explosive than dividends then it can be concluded that rational bubbles are not present since they would generate an explosive component to stock prices 2 using unit root tests autocorrelation patterns and cointegration tests to implement this procedure diba and grossman 1988b p 529 state that the analysis supports the conclusion that stock prices do not contain explosive rational bubbles this paper shows that the above battery of tests is in fact unable to detect an important class of rational bubbles the point is demonstrated by constructing rational bubbles that appear to be stationary when unitroot tests are applied even though they are explosive in the relevant sense simulations show that when such bubbles are present stock prices will not appear to be more explosive than dividends on the basis of these tests even though the bubbles are substantial in magnitude and volatility the presence of rational bubbles in actual stock prices thus remains an open question

cropland allocation effects of agricultural input subsidies in malawi summary we measure the impacts of malawi s farm input subsidy program on the cropland allocation decisions of farmers in kasungu and machinga districts in central and southern malawi using a two step regression strategy to control for endogenous selection into the program we find positive correlations between participation in the program and the amount of land planted with maize and tobacco furthermore results suggest that participating households simplified crop production by allocating less land to other crops e g groundnuts soybeans and dry beans our findings have implications for policies aimed at promoting both food self sufficiency and crop diversification in low income settings 2011 elsevier ltd all rights reserved

market access by smallholder farmers in malawi implications for technology adoption agricultural productivity and crop income abstract in malawi maize is the major crop and food staple given limited off farm employment opportunities much needed increases in household income for improving food security must come from gains in agricultural productivity through better technology and more profitable crops in the past hybrid maize and more recently tobacco were promoted by policy for increasing smallholder income an analysis of determinants of adoption of these two crops and related income effects is presented apart from factor endowment and exposure to agroecological risks differences in the household s access to financial and commodity markets significantly influence its cropping shares and farm income
