heterogeneous effects of international migration and remittances on crop income evidence from the kyrgyz republic this paper uses a unique representative household budget survey from the asian development bank to analyze the impact of international migration and remittances on crop income of rural farmers in the kyrgyz republic unlike other studies we allow the impact of remittances to be different for farmers with different land size and test whether reduced labor availability is more relevant for permanent than for seasonal migrants we find that losing family members has a significant negative effect on crop income but only for permanent migrants remittances partially compensate for this but their positive impact decreases with farm size

non agricultural earnings in peri urban areas of tanzania evidence from household survey data abstract this study draws on purposive survey data of approximately 600 households in peri urban tanzania to describe the degree and nature of non farm diversification in these settings with the exception of relatively dynamic cities such as dar es salaam and arusha overall non farm incomes shares are not unambiguously higher than in rural areas as a whole non farm income shares rise sharply and monotonically with quintiles defined in terms of per capita food consumption in that sense the sector appears to offer an important route out of poverty the evidence suggests that education and access to infrastructure are important determinants of non farm incomes in peri urban areas women appear to be poorly placed vis a vis the non farm sector even after controlling for education age and other characteristics kinship and tribal affinities and time devoted to communal activities appear to deter entrepreneurial activity and non farm employment but trust in officials and public servants and strong heterogeneous village associations are important in stimulating non farm activity

oligopsony power a forgotten dimension of food marketing discussion the three papers offer engaging discussions of oligopsony power at the first handler level in agricultural markets the papers fill an important gap in the literature and thus are important reading for those interested in market power issues in markets for raw agricultural commodities in addition to making the case for increased attention to the potential for oligopsony power at the first handler level each of the papers makes important methodological contributions in offering analytical and empirical approaches for evaluating this oligopsony power although linked by a common theme the three papers differ significantly in their approaches to the market power issue as rogers and sexton note statistics on concentration at least on the sellers side of the market suggest that farm related industries are highly concentrated and that this concentration has increased significantly in recent years for example the four firm concentration ratio cr4 in the steer and heifer slaughter industry has gone from 30 in 1978 to 70 in 1988 purcell 1990a likewise the cr4 for the flour milling industry has gone from 37 in 1980 to over 65 in 1991 brester and goodwin the period 1977 87 was one of four great u s merger movements approximately 400 billion was spend on industrial mergers during this period with food and tobacco firms being the major players connor and geithman these mergers were fueled in part by relaxed restrictions on mergers by federal antitrust agencies after 1980 these statistics lead one to suspect the existence of market power influences in farm related industries however a high degree of concentration in an industry does not confirm the existence of discriminatory market power practices after many years of debate among industrial organization economists the relationship between industry concentration and the exercise of market power remains inconclusive the papers at l ast implicitly take as given the premise that industry concentration implies the existence of collusive market power practices an alternative view presented by demsetz holds that scale economies or other competitive advantages lead to increased concentration in many industries without implying the existence of welfare diminishing market power pricing practices in such cases increased concentration may result in more efficient use of resources of course this alternative view often assumes that entry and exit in an industry are relatively easy and thus that firms in highly concentrated industries are disciplined by the threat of competition evidence of scale economies in the food processing sector has been offered in recent research for example ward found that significant economies of size existed in the

nonfarm income diversification and household livelihood strategies in rural africa concepts dynamics and policy implications abstract asset activity and income diversification lie at the heart of livelihood strategies in rural africa this paper introduces a special issue on the topic income diversification and livelihoods in rural africa cause and consequence of change we concentrate on core conceptual issues that bedevil the literature on rural income diversification and the policy implications of the empirical evidence presented in this special issue

remittances investment and rural asset accumulation in pakistan internal and external migration can have a profound impact on rural asset accumulation in most third world countries in many african asian and latin american countries the bulk of the labor force still lives in the countryside in these countries the large difference between expected rural and urban or foreign incomes coupled with the risk reducing functions of migration causes workers to migrate either to urban centers or abroad the remittances defined as the money or goods sent home by migrant workers can have a large effect on the accumulation of assets in these rural areas for example an inflow of external remittances to rural households at the upper end of the income distribution could increase land accumulation by the rich in general terms the effect of remittances on asset accumulation in a rural third world economy depends on answers to three questions a who migrates b how much net income do migrants remit and c what are the marginal effects of these remittances on household consumption and investment because of data limitations in this article i propose to examine only the first and the third questions other researchers have addressed the second issue in the past surprisingly little attention has been focused on the question of the marginal effects of remittances on household consumption and investment in the rural third world this inattention has been due to three considerable methodological problems the first is fungibility because remittances are like any other form of cash income it is difficult to associate this income source with any particular changes in household expenditure behavior the second problem relates to the multiple round effects of remittances on the local economy for example an inflow of remittances into a rural area may lead to a surge in expenditures in housing which may in turn create new income and employment opportunities for the poor and unskilled unfortunately however few studies have

the impact of income diversification among fishing communities in western kenya abstract past studies have shown that fishing communities in developing countries are generally poor one potential strategy for reducing poverty among these communities is income diversification this study investigates the impact of income diversification on incomes of fishing communities living on the kenyan shores of lake victoria using four propensity score matching methods we find evidence that income diversification increases the incomes of fish workers the strongest impact appears to be among fishers fish enterprise employees and fish workers in the non export beach based on these results income diversification can be considered a poverty reduction strategy among fishing communities in western kenya

emigration to south africa s mines this paper presents a simultaneous econometric model of both the determinants of international migration to the south african mines and of some of the economic consequences for each of the labor supplying countries not only are the short run effects of labor withdrawal on traditional crop cultivation and the domestic wage labor markets considered but also the long term effects of savings from mine earnings invested in crops and cattle in the home countries the experiences of botswana lesotho malawi mozambique and the south african homelands are compared it is shown that emigration to the south african mines has reduced crop production in the subsistence sectors of botswana lesotho malawi and the south african homelands in the short run but the results also suggest that earnings of migrants have enhanced both crop productivity and cattle accumulation in the longer run except in lesotho excerpt

migration and income diversification evidence from burkina faso this paper uses limited dependent variable methods and new data from burkina faso to test the impact of inter continental and continental migration on activity choice and incomes in rural households econometric evidence supports our theoretical expectation that the impact of emigration varies both by migrant destination and production activity we find no evidence of either positive or negative effects of continental migration on agricultural or livestock activities and only a small negative impact on non farm activities however inter continental migration which tends to be long term and generates significantly larger remittances stimulates livestock production while being negatively associated with both staple and non farm activities

costs and benefits of livestock systems and the role of market and nonmarket relationships in developing countries livestock are kept not only for their physical products but also for insurance financing and to display status though this range of purposes is acknowledged livestock policies nevertheless often emphasize physical production a limited perspective that hampers the formulation and implementation of effective livestock policies this article presents a comprehensive appraisal of costs and benefits of livestock systems that takes into account the institutional environment of livestock keepers indicators are developed that capture quantify and organize not only the benefits resulting from the physical production but also those from the intangible functions the method is illustrated by an analysis of cattle in the western province of zambia the results indicate that the perspective on livestock systems developed more closely reflects the observed decisions of the livestock keepers

using evidence of household income diversification to inform study of the rural nonfarm labor market in africa abstract the labor market literature in developing countries has seldom drawn on the studies of rural household income diversification this paper draws on such studies to inform future study of the rural nonfarm labor market in africa the review of evidence provides some surprising departures from traditional images of nonfarm activities of rural households among the most striking is the dominant importance in the majority of case study areas of nonfarm wage labor as compared to self employment of nonfarm sector earnings as compared to farm sector wage earnings and of local nonfarm earnings as compared to migration earnings the most worrying finding was the poor distribution of nonfarm earnings in rural areas despite the importance of these earnings to food security and farm investments this poor distribution implies significant entry barriers and market segmentation it is probable that this will lead over time to an increasingly skewed distribution of land and other assets in rural africa

diversification strategies and adaptation deficit evidence from rural communities in niger summary the paper provides fresh empirical evidence on the adaptation process in niger rural communities using original longitudinal socio economic panel data merged with granular geo referenced climatic information we identify the main drivers and impacts of crop and labor diversification which constitute two livelihood strategies on moderating the adaptation deficit in doing so we account for the interdependence between the two diversification practices and potential reverse causality between welfare outcomes and diversification behavior moreover we condition the impacts of diversification on different sections of the welfare distribution to capture potential non linear effects our results reveal that the diversification has positive and significant welfare impacts when most vulnerable households rely on it as an adaptation strategy to mid run climate variability and as a coping strategy to short run market shocks at the same time our results find lower but still positive impacts for well endowed households that are likely to diversify their activity portfolio given the very limited presence of policy support we conclude that the rural nigerien communities are characterized by a large and autonomous adaptation response which constitutes a key leverage mechanism for policy makers we thus suggest government interventions aimed at supporting the most important diversification drivers but also aimed at straightening some channels such as network infrastructures or the promotion of local crop varieties which may have a greater potential in triggering diversification

flexible inflation forecast targeting evidence from canada we test whether the bank of canada pursues a flexible inflation forecast target one that weights output growth as well as inflation for the period 1996 2007 we find evidence that the bank did effectively pursue such a target over the forecast horizon of 12 to 18 months we find the relative weight that the bank gives to output growth in its target to be positive and statistically significant within the range of 0 2 to 0 4 resume la poursuite de cibles de prevision d inflation flexibles resultats pour le canada on met au test la proposition a savoir si la banque du canada poursuit une cible flexible de prevision d inflation une cible qui tient compte de la croissance du produit tout autant que l inflation pour la periode 1996 2007 les resultats montrent que la banque a poursuivi une cible sur un horizon de prevision de 12 a 18 mois on montre que la ponderation relative que la banque donne a la croissance du produit dans son ciblage est positive et statistiquement significative dans l eventail entre 0 2 et 0 4

transforming rural economies migration income generation and inequality in rural mexico abstract we analyse how migration shapes the distribution and sources of rural income using nationally representative panel data from mexico income source gini decompositions provide some support for the migration diffusion hypothesis nevertheless migration s influence on other income sources and household re ranking substantially alter distributional impacts we find significant impacts of migration on non remittance income as well as changes in the effects of non migration activities on inequality over time we conclude that migration is transforming rural economies in ways that go beyond the scope of most past research on migration and inequality

the shadow value of migrant remittances income and inequality in a household farm economy this article offers econometric evidence that income remittances sent home by family migrants stimulate household farm incomes indirectly by relieving credit and risk constraints on household farm production a high but unequally distributed shadow value of migrant remittances appears to reinforce an equalising direct effect of remittances on the income distribution across a sample of household farms in rural mexico

what does the bundesbank target abstract although its primary ultimate objective is price stability the bundesbank has drawn a distinction between its money focused strategy and the inflation targeting approach recently adopted by a number of central banks we show that holding constant the current forecast of inflation german monetary policy responds very little to changes in forecasted money growth we conclude that the bundesbank is much better described as an inflation targeter than as a money targeter an additional contribution of the paper is to apply the structural var methods of b bernanke and i mihov measuring monetary policy working paper no 5145 national bureau of economic research cambridge ma june 1995 to determine the optimal indicator of german monetary policy we find that the lombard rate has historically been a good policy indicator although the use of the call rate as an indicator cannot be statistically rejected

does migration raise agricultural investment an empirical analysis for rural mexico the effect of remittances on capital accumulation remains a contested topic this paper uses a panel data set from rural mexico to investigate the impact of remittances on agriculture and livestock investments after controlling for the endogeneity of migration through an instrumental variable estimation our empirical results show that international migration has a significantly positive effect on the accumulated agricultural assets but not on livestock capital this suggests that households use the capital obtained from international migration only to overcome liquidity constraints for subsistence production whereas migration itself seems to be the superior investment option compared to other productive activities such as livestock husbandry

why u s money does not cause u s output but does cause hong kong output abstract standard econometric tests for whether money causes output will be meaningless if monetary policy is chosen optimally to smooth fluctuations in output if u s monetary policy were chosen to smooth u s output we show that u s money will not granger cause u s output indeed as shown by rowe and yetman 2002 identifying policy makers objectives an application to the bank of canada canadian journal of economics 35 2 239 256 if there is a say 6 quarter lag in the effect of money on output then u s output will be unforecastable from any information set available to the fed lagged 6 quarters but if other countries for example hong kong have currencies that are fixed to the u s dollar hong kong monetary policy will then be chosen in washington d c with no concern for smoothing hong kong output econometric causality tests of u s money on hong kong output will then show evidence of causality we test this empirically our empirical analysis also provides a measure of the degree to which macroeconomic stabilisation is sacrificed by adopting a fixed exchange rate rather than an independent monetary policy

migration and rural welfare the impact of potential policy reforms in europe summary this paper uses an agricultural household model in an imperfect market environment and data from burkina faso to explore the impact of potential immigration policy reforms in europe on the welfare of rural households simulation results demonstrate that in contrast to continental migration increased intercontinental migration has strong positive household welfare effects similarly an increase in the stay abroad of intercontinental migrants impacts positively on welfare of the migrant sending household results of these simulations lend support to the introduction of a tmp which would in addition to facilitating migration control in host economies improve the welfare of sending households by allowing for increased engagement in intercontinental migration the temporary nature of such a program would ensure that dutch disease effects would be mitigated through eventual migrant return

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

the roles of destination gender and household composition in explaining remittances an analysis for the dominican sierra two non exclusive hypotheses about what motivates remittances sent by dominican migrants to their rural parents in the sierra are tested a an insurance contract taken by parents with their migrant children and b an investment by migrants in potential bequests results show that the relative importance of these two motives to remit is affected by destination us vs cities in the dominican republic gender and household composition the insurance function is mainly fulfilled by female migrants to the us only when a male is the sole migrant in his household does he play the role of insurer investment by contrast is pursued by both males and females but only among those migrating to the us d 2002 elsevier science b v all rights reserved

canadian inflation targeting this paper examines the intellectual environment in canada that led to the adoption of inflation targets starting in 1991 reviews some of the canadian contributions to the vast literature on inflation targeting and presents evidence in support of the view that the implementation of inflation targeting in canada has been particularly successful when compared with the experiences of other inflation targeting countries and the us

determinants and effects of income diversification amongst farm households in burkina faso using four years of household data from three agroecological zones in burkina faso sahelian sudanian and guinean the article examines the determinants and effects of household income diversification harvest shortfalls and terms of trade are found to drive diversification but land constraints do not income diversification is associated with higher incomes and food consumption and more stable income and consumption over years

short term labour migration from the republic of armenia to the russian federation we explore the determinants of short term labour migration from armenia to russia based on a unique panel dataset a dynamic switching regression model with endogenous switching is applied our evidence pinpoints migration experience the expected individual income gap from migration low job opportunities in armenia and the possibility of diversifying income risks as the most important determinants family ties turn out to be insignificant the hypothetical income gap is about 280 per cent several explanations are provided for the fact that some individuals do not migrate in spite of a large income gap

remittances poverty inequality and welfare evidence from the central plateau of burkina faso abstract this paper applies gini and concentration coefficient decomposition as well as the foster greer thorbecke poverty index and the stark yitzhaki welfare index to new data from four villages in burkina faso to compare the marginal effects of remittances from intercontinental and intra african migration on inequality poverty and social welfare evidence is found that intra african remittances reduce inequality while intercontinental remittances have the opposite effect also it is found that although remittances from intercontinental migration are associated with much lower incidence depth and severity of poverty the marginal impact of remittances from this form of migration on social welfare is limited because recipients do not include the rural poor

migration and technical efficiency in cereal production evidence from burkina faso this article uses a double bootstrap procedure and survey data from burkina faso in a two stage estimation to explore ways in which continental and intercontinental migration determine efficiency in cereal production of rural households findings suggest that continental migration has a positive relation and intercontinental migration no relation with technical efficiency for continental migrant households migration has removed surplus male labor a cause for inefficiency in production intercontinental migration leads to a gender imbalance in the household which cannot be compensated for by investments in farm equipment the failure of intercontinental migration to transform cereal production from traditional to modern is attributed to an imperfect market environment

using shadow wages to estimate labor supply of agricultural households with few exceptions most studies of the labor demand and supply decisions of agricultural households in developing countries have relied on the empirical advantages of separability given the questionable nature of some of the assumptions sufficient for separability i apply a recent methodology that accounts for the simultaneity between the production and consumption decisions of a farm household using data from rural india direct estimates of the marginal productivities shadow wages of family male and female labor are derived from a cobb douglas agricultural production function the estimated shadow wages and income are then used as regressors in a structural model of labor supply

the relation between price and marginal cost in u s industry an examination of data on output and labor input reveals that some u s industries have marginal cost well below price the conclusion rests on the finding that cyclical variations in labor input are small compared with variations in output in booms firms produce substantially more output and sell it for a price that exceeds the costs of the added inputs the paper documents the disparity between price and marginal cost where marginal cost is estimated from annual variations in cost it considers a variety of explanations of the findings that are consistent with competition but none is found to be completely plausible

determinants of income diversification amongst rural households in southern mali abstract household level panel data from a representative sample of rural households in southern mali describing the different sources of household income are used to examine the determinants of income diversification a conditional fixed effects logit model is employed in the analysis to control for household specific effects we find evidence that poorer households have fewer opportunities in non cropping activities such as livestock rearing and non farm work and hence less diversified incomes this appears to reflect their relative lack of capital which makes it difficult for them to diversify away from subsistence agriculture the results also indicate that households in remote areas are less likely to participate in the non cropping sector than their counterparts closer to local markets while households with educated heads are more likely to participate in the non farm sector than those with illiterate heads the significance of entry constraints in explaining portfolio diversification suggests that the role of government in making assets as well as improved infrastructure available to poorer households is still essential in promoting income diversification

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

migration and incomes in source communities a new economics of migration perspective from china the objective of this paper is to understand the effects of china s migration on source communities and to discuss their policy implications we draw from new economics of labor migration nelm theory to understand how migration and migrant remittances can relax or tighten market constraints in china s rural economy using simultaneous equation econometric techniques and household survey data from china we estimate net sectorspecific effects of migration on rural household income focusing on farm production and self employment our econometric findings indicate that the loss of labor to migration has a negative effect on household cropping income in source areas however we provide evidence that remittances sent home by migrants positively compensate for this lost labor effect contributing to household incomes directly and indirectly by stimulating crop and possibly self employment production this finding offers evidence in support of the nelm hypothesis that remittances loosen constraints on production in the imperfect market environments characterizing rural areas in less developed countries taking into account both the multiple effects of migration and the change in household size participating in migration increases household per capita income between 14 and 30 percent migration and incomes in source communities a new economics of migration perspective from china china is experiencing the largest peacetime flow of labor out of agriculture ever witnessed in world history solinger 1999 rozelle et al 1999 despite the rapid expansion of labor migration china s work force is still disproportionately employed in agriculture compared to other countries at similar levels of per capita gdp taylor and martin 2001 hence as china s economy continues to expand the flow of labor to urban areas will continue and even accelerate johnson 1999 the massive flow of labor away from farms has intensified research interest in china s migration in recent years however as in the broader literature on migration in less developed countries most recent studies on china s migration have focused on determining the size and composition of the labor flow macroeconomic implications of increased migration and the effects of migration on urban areas zhao 1999 yang 1999 1997 less emphasis has been placed on researching the effects of migration on the rural communities that migrants leave even though evidence shows that the rural household in the village of origin is typically the central concern of all those involved in migration both those who leave and those who stay behind exceptions include wang and zuo 1999 bai 2001 moreover the recent increase in migration has left policy makers particularly concerned regarding the way source communities will be affected moa 1999 they are concerned that as labor flows away from farms food production and crop income will decline potentially threatening china s food security furthermore policy makers are concerned about the increasing gap between urban and rural household incomes if migration exacerbates this gap some fear that as it grows rural residents eventually will flood cities ill equipped to absorb them others fear that discontent over a rising urban rural income gap could even spill over into political unrest yang 1999 because china s markets and other modern economic institutions are still relatively undeveloped migration may play a pivotal role in creating or overcoming constraints caused by the lack of well functioning markets and or institutions knight and song 1999 benjamin and brandt 2000 the new economics of labor migration nelm literature analyzes migration as a household decision rather than as an individual decision stark 1991 the nelm hypothesizes that rural households facing imperfect market environments decide

in search of the motives behind us fiscal macroeconomic policy in this paper optimal control tehniques are applieed to estimate the motives behind us fiscal macroeconomic policy starting from a range of possible objesctives and given the perception of policy makers about the environment in which they operate the priorities of policy makers are estimated on the basis of their past actions our statistical approach allows for testing the empirical relevance of alternative hypotheses with respect to the objectives of governments demoeratic and republican administrations are found to aim at different targets some support is also found to political business cycle theories the views expressed here are not necessarily those of the ductch central bank

shadow wages and peasant family labour supply an econometric application to the peruvian sierra a striking feature of developing economies is the large proportion of the work force that is self employed lack of widespread labor market participation in the agricultural sector can pose a major obstacle to the empirical implementation of economic models of the peasant household whether because wage data are simply not available or because the assumptions required to make use of wage data stretch the bounds of credulity this paper develops a methodology for estimating a structural labor supply model for primarily self employed peasant households which holds under a general agricultural technology and set of labor market conditions the unique feature of the approach is that the opportunity cost of time or shadow wage of household workers is explicitly estimated from an agricultural production function and is subsequently used to identify a set of structural labor supply parameters recent household survey data from rural peru is employed to estimate and perform various diagnostic tests on the model the empirical findings lend support to the hypothesis that peasant households allocate their members time as if to maximize a family utility function and moreover demonstrate the tractability of the shadow wage methodology and its usefulness in estimating more elaborate time allocation models

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

is canada an optimal currency area an inflation targeting perspective we propose a method based on the currency union model of gali and monacelli 2008 to determine whether a region within an existing currency area belongs in the currency union the method involves assessing the predictability of regional inflation rates at medium term horizons we apply the method to the canadian provinces and find that for all but alberta there is little evidence of costs in terms of inflation arising from national monetary policy for alberta the evidence suggests that they are not as well served by the inflation targeting framework and that a more flexible policy environment might improve inflation outcomes

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

identifying a policymaker s target an application to the bank of canada we develop a new way to test hypotheses about policymakers targets and imple ment that test for canadian monetary policy for example if the bank of canada is targeting a 2 per cent inflation rate and if the bank s instrument takes eight quarters to affect inflation then deviations of inflation from 2 per cent should be uncorrelated with the bank s informa tion set lagged eight quarters we show that there was a major change in the bank s objec tives near the time when formal inflation targets were announced and that the bank has indeed been targeting inflation since then jel code e52 e61
