the ambivalent impact of coffee certification on farmers welfare a matched panel approach for cooperatives in central kenya certification is promoted to improve rural welfare through better market access and improved agricultural practices we compare net effects of fairtrade and utz certified coffee production in central kenya using a matched panel from 218 farm households that belong to three cooperatives and were visited twice in 2009 and 2013 we distinguish between effects at field farm household cooperative community and market levels both certification regimes improved coffee returns but fairtrade was more effective in coffee processing whereas utz contributed to productivity under stagnating coffee prices fairtrade farmers increased their coffee specialization while utz farmers reduced coffee areas but increased yield

credit natural disasters coffee and educational attainment in rural honduras summary this paper exploits a two stage estimation approach to examine the impact on secondary school attainment in rural honduras of four key variables affecting household choices wealth credit access crop choice and shocks the first stage estimates the probability that a household is credit constrained while the second estimates secondary school educational attainment of appropriately aged children the second stage includes variables for crop selection and household wealth shocks from hurricane mitch in addition to other characteristics of the child household and community that can influence educational attainment credit constrained households have lower educational attainment and are more likely to be adversely affected by negative shocks

cash transfer programs with income multipliers procampo in mexico abstract cash transfer programs create multiplier effects when recipients put the money they receive to work to generate further incomes when this is the case the ultimate income effects are multiples of the amounts transferred we analyze the procampo program in mexico that was introduced to compensate farmers for the anticipated negative effect of nafta on the prices of basic crops the transfer rules and the timing of the panel data collected allow unique control of biases in this impact analysis we find that the multiplier among ejido sector recipients is in the range 1 5 2 6 multipliers are higher for households with medium and large farms low numbers of adults in the household nonindigenous backgrounds and located in the center and gulf regions high multipliers reflect income opportunities that had remained unrealized due to liquidity constraints that are relaxed by the transfers opportunities come from the asset endowments that these households received through the land reform particularly irrigated land and they are enhanced by access to technical assistance

a money demand equation for brazil abstract the estimates for the money demand equation reported below are based on quarterly time series for brazil for the 1966 i 1979 iv period they show that the long run income elasticity of the demand for money is roughly unitary and the rate of interest does affect the demand for money exclusion of the latter variable therefore leads to biased estimates of the coefficients of the money demand equation the empirical evidence also points out that the rate of inflation affects the demand for money only to the extent that it is necessary to change nominal cash balances to adjust cash holdings to their desired level either nominal interest rates capture the expected inflation rates or goods inventories are not an important alternative to holding money in brazil

the impact of fair trade certification for coffee farmers in peru smallholder farmers producing for fair trade market outlets are usually considered to benefit from better prices and stable market outlets however many empirical studies verifying this impact suffer from strong selection bias this study uses a balanced sample of fair trade farmers and likewise nonfair trade producers of organic and conventional coffee from peru to compare the net effects on production income and expenditures wealth and investments and attitudes and perceptions after careful matching we find only modest direct income and production effects but significant changes in organization input use wealth and assets and risk attitudes moreover important differences between farmers with early and more recent ft affiliation are registered

rural nonfarm employment and incomes in latin america overview and policy implications abstract rural nonfarm employment rnfe and incomes rnfi are crucial to latin american rural households the 11 rural household income studies in this volume reviewed in this paper use 1990s data and show that rnfi averages 40 of rural incomes rnfi and rnfe have grown quickly over the past three decades the review of evidence provided some surprising departures from traditional images of nonfarm activities of latin american rural households in terms of shares of rural incomes 1 nonfarm wage incomes exceed self employment incomes 2 rnfi far exceeds farm wage incomes 3 local rnfi far exceeds migration incomes 4 service sector rnfi far exceeds manufactures rnfi these findings suggest the need for more development program attention to wage employment in the service sector versus the traditional focus on small enterprise manufactures moreover poor households and zones tend to have higher shares in their incomes but lower absolute levels of rnfi as compared to richer households and zones the rnfe of the poor tend to be the low paid nonfarm equivalent of semi subsistence farming raising the capacity of the poor to participate in the better paid types of rnfe is crucial via employment skills training education infrastructure credit finally rnfe has grown fastest and been most poverty alleviating where there are dynamic growth motors in particular in the agricultural sector but also in tourism links to urban areas mining and forestry this means that developing rnf jobs cannot be done at the expense of programs promoting agricultural development

conditional cash transfers shocks and school enrolment in nicaragua abstract this work estimates the impacts of a nicaraguan cash transfer programme that pays households conditional on school attendance and family visits to health clinics and seminars a model explores the impact on school enrollment of cash transfers given differences in household wealth labour market opportunities and negative shocks a difference in difference estimation for distinct wealth cohorts reveals that the programme led to a significant improvement in school enrollment outcomes among poor households in coffee cultivating communities the results cast doubt however on proposals that broadly link conditional cash transfers to negative shocks

do farmers benefit from participating in specialty markets and cooperatives the case of coffee marketing in costa rica1 historically low prices in the conventional coffee market have caused financial and social hardship among coffee farmers in the face of this crisis specialty markets have attracted the attention of the international donor community these market segments have shown consistent growth over the last decade and exhibit price premiums in international markets therefore if higher prices are passed on to farmers access to specialty markets could help to alleviate the crisis brought on by low prices in the conventional sector the present study attempts to identify the factors that determine farmers participation in specialized markets and whether participation in these markets leads to higher prices for farmers a two stage model is used to analyze farmers marketing decisions and their effect on the prices received this procedure allows us to control for the endogeneity bias introduced by the marketing choice our results indicate that farmers participating in the specialty coffee segment do in fact receive higher prices than those participating in conventional channels additionally we find that participation in cooperatives has a positive impact on the probability that a farmer chooses to grow specialty coffee and analogously on the prices that they receive based on these results it seems that efforts to increase participation in the specialty coffee segment and in cooperatives would help to lessen some of the hardships brought on by low prices in the conventional coffee sector

have coffee producers benefited from the new domestic cherry market evidence using panel data from rwanda the article assesses the effects of the new domestic cherry market on coffee growing households in rwanda using panel data findings from combined first differenced with instrumental variable specification and other estimation methods provide evidence that farmers who sell to the cherry market do not increase their expenditures compared to farmers selling to the traditional parchment market the different time lags in terms of when farmers started selling to the new cherry market may explain the lack of statistically significant differences across the two groups it is possible that farmers will adjust their expenditure patterns in subsequent periods after year over year market trends become more apparent to them

rice farmers preferences for fairtrade contracting in benin evidence from a discrete choice experiment abstract private standards such as fairtrade have emerged as a response to consumer civil society and corporate concerns about the production conditions of imported food many studies have investigated the welfare implications of smallholder participation in fairtrade schemes and consumers willingness to pay for fairtrade and other labelled products on the other hand no study has yet investigated farmers preferences for fairtrade and other private standards such insights would be valuable to improve the efficiency of certification schemes and ensure that they are tailored to farmers needs using a choice experiment this study investigates the preferences of smallholder rice farmers in benin for fairtrade and organic standards and compares the value of three types of contracts domestic fairtrade and fairtrade organic the results indicate that farmers positively value contracts but prefer domestic over fairtrade contracts because the former involve fewer requirements at current market prices farmers are willing to accept a fairtrade contract that includes fertiliser and child labour restrictions and a social premium but they are not willing to accept a fairtrade organic contract that completely prohibits chemical input use the results imply that adding organic requirements to fairtrade contracts may undermine the adoption and spread of fairtrade certification in the beninese rice sector

fair trade organic coffee cooperatives migration and secondary schooling in southern mexico abstract we explore three trends in rural southern mexico fair trade coffee migration and conditional cash transfers that could explain the rapid rise in education from 1995 2005 using survey data from 845 coffee farming households in oaxaca and chiapas mexico results from a household fixed effects model show that household participation in a fair trade organic cooperative contributed to about a 0 7 year increase in schooling for girls us migration opportunities appear to have even stronger positive impacts on schooling for females although participation in fair trade organic cooperatives appears also to have increased male schooling increased migration opportunities have had an indeterminate effect for males

exploring double side selling in cooperatives case study of four coffee cooperatives in rwanda apart from the difficulty to attract new members leakage of sales outside the cooperative is a major challenge for the coffee cooperatives in rwanda local independent traders still constitute a major market for coffee producers yet cooperatives also accept the produce from non members and pay them the same price our objective in this paper is to analyse the importance of this phenomenon of double side selling we collected data from a sample of 170 coffee farmers we use a probit model to analyse characteristics linked to cooperative membership and to study double side selling we describe the trade relationships between farmers and the cooperative on the one hand and between farmers and traders on the other by the attributes of transaction costs involved in the trade of coffee membership characteristics include easy access to labour land tenure risk aversion and mutual trust between farmers and cooperatives management preference to sell to traders can be explained by the trust farmers seem to have in them after the repeated transactions in credit and basic consumption items and by long term relationships in the community

cointegration and tests of a classical model of inflation in argentina bolivia brazil mexico and peru abstract we develop a classical model of inflation with rational expectations that carries a number of testable implications first money growth and inflation are cointegrated second the changes in real money demand the equilibrium error anticipate future monetary policy third cointegration between money growth and inflation implies as campbell and shiller journal of political economy 1987 95 1062 1088 and journal of economic dynamics and control 1988 12 505 522 show cross equation restrictions readily generated from an error correction representation of the variables our results show that the allegedly different inflationary experiences of argentina bolivia brazil mexico and peru are consistent with this classical model of inflation in all countries the data fail to reject these three conditions in all but one of the periods studied

decoupling standards from practice the impact of in house certifications on coffee farms environmental and social conduct in this paper we investigate whether coffee farms that have been granted in house socio environmental certification from a global buyer display better social and environmental conduct compared to non certified farms we perform an econometric analysis using data from an original cross country survey covering 575 farms in various regions of brazil colombia costa rica guatemala and mexico we find that farms that have been granted in house certification demonstrate better environmental but not better social conduct than non certified farms we find also that the positive relationship between in house certification and environmental conduct is stronger if the farm sells to a cooperative and if it is located in an institutionally weak country finally we find that the institutional strength of the farm s home country has a positive influence on its social conduct we discuss how our analysis contributes to the literature on the social and environmental impacts of certifications and to scholarship in global value chains social and environmental upgrading

the economics of quality in the specialty coffee industry insights from the cup of excellence auction programs this study estimates price determinants for specialty green coffee auctions using records from the 2004 2010 cup of excellence programs hosted by the alliance for coffee excellence while some literature on coffee has focused on certifications and sustainability labels the discussion of price determinants has been limited this article replicates one of the first publications on price determinants and formulates a new model to more accurately describe the market we include the necessary additional variables and estimate the model using a truncated maximum likelihood estimation technique while sensory quality has a strong effect on price the highest premiums stem from obtaining a top rank compared to other coffees from the same country and north american buyers are more responsive to sensory quality than buyers in asian and european markets jel classifications c24 d44 q13

the determinants of nonfarm activities and incomes of rural households in mexico with emphasis on education abstract this paper presents the main results of a study of the effects of education as well as other household assets on the choice of activities and incomes of rural mexican households our study examines the various income sources as well as the education of the household s head and its members implications are drawn for rural education and development policies to promote rural nonfarm incomes and employment

fair trade organic coffee production in nicaragua sustainable development or a poverty trap abstract this article assesses the impact of fair trade organic coffee production on the well being of small scale farmers in nicaragua studying the results of organic management is crucial for evaluating the advantages of fair trade because approximately half of all fair trade coffee is also organically certified a wide range of farmers representatives of cooperatives and export companies in nicaragua were interviewed during seven months of field work between 2005 and 2008 fair trade organic production raises farmer income when low intensity organic farming is an alternative to low intensity conventional farming however low intensity farming produces very little coffee in the case of the most marginalized farmers keeping these farmers in poverty with higher intensities of management the economic advantages of fair trade organic production largely depend on prices in the mainstream market

fair trade organic coffee rural livelihoods and the agrarian question southern mexican coffee families in transition summary we use a random sample of coffee producing households in southern mexico to compare opportunities associated with government subsidies and migration to the role of fair trade organic coffee in household livelihoods although land and labor returns among fair trade organic coffee growers are higher than for conventional growers differences in yields are more important than price premiums moreover investment in education and labor opportunities outside coffee dominate those in fair trade organic coffee the results highlight the value of an integrated approach to the agrarian question that improves productivity and prices and supports other pathways for improving incomes

a money demand equation for brazil comments and additional evidence abstract in an article in this journal cardoso 1983 presents evidence on money demand in brazil during the period 1966 1979 re estimating cardoso s equations using the data provided in her paper we find evidence that her estimates are subject to serious statistical problems we suggest an alternative estimating strategy our results support several of cardoso s estimates the main difference concerns the relative importance of the nominal interest rate and the rate of inflation in contradiction to cardoso s our results indicate that the inflation rate is statistically much more significant than the nominal interest rate

bee pollination and productivity growth the case of alfalfa the spread of commercial pollination has received little attention in the literature analyzing the growth in u s agricultural productivity between world war i and 1960 growers of most fruits nuts and seeds came to realize that intensive bee pollination was essential to achieve high yields alfalfa seed growers were among the last groups to adopt commercial pollination this article examines the dramatic impact that concentrating bees in alfalfa seed fields had on yields which resulted in the restructuring of the alfalfa industry the fourth most valuable commodity grown in the united states in the 1950s

capitals and capabilities a framework for analyzing peasant viability rural livelihoods and poverty abstract on the basis of themes emerging in current debates on rural development in latin america this paper develops an analytical framework for analyzing rural livelihoods in terms of their sustainability and their implications for rural poverty the framework argues that our analyses of rural livelihoods need to understand them in terms of a people s access to five types of capital asset b the ways in which they combine and transform those assets in the building of livelihoods that as far as possible meet their material and their experiential needs c the ways in which people are able to expand their asset bases through engaging with other actors through relationships governed by the logics of the state market and civil society and d the ways in which they are able to deploy and enhance their capabilities both to make living more meaningful and to change the dominant rules and relationships governing the ways in which resources are controlled distributed and transformed in society particular attention is paid to the importance of social capital as an asset through which people are able to widen their access to resources and other actors

after neoliberalism the politics of reregulation in mexico neoliberal economic reforms rather than unleashing market forces can result in new institutions for market governance by vacating institutionalized policy domains neoliberal reforms can trigger two step reregulation processes as first political entrepreneurs launch projects to build support coalitions by reregulating markets and second societal groups respond to these projects by mobilizing to influence the terms of reregulation depending on the strengths and strategies of politicians and societal groups reregulation processes result in varied institutions for market governance the article develops this argument by analyzing how neoliberal reforms in mexico led to the construction of distinct institutions for market governance across four states chiapas guerrero oaxaca and puebla the findings from mexico highlight the importance of moving beyond the questions of why developing countries choose neoliberal policies and how they implement them students of the political economy of development should shift their attention instead to understanding the kinds of new institutions that replace those destroyed or displaced by neoliberal reforms

the effect of specialty coffee certification on household livelihood strategies and specialisation abstract farm certification is rapidly becoming a sine qua non for access to specialty coffee markets at the centre of these changes are smallholder coffee producers responsible for 80 of global coffee production although rural households are known to depend on more than agricultural production alone the literature on specialty coffee and certification has rather narrowly focused on coffee income and production in this study broader impacts are explicitly taken into account household income was decomposed into categories corresponding to specific income generating activities and coffee income was broken down into price yield and area effects results show that coffee certification encourages farmers to specialise in coffee production increasing coffee income but not total household income at least not in the short run the time and effort required to attain the higher coffee income offered by certified production means farmers have to give up other activities this substitution effect cancels out the income effect such that there is no increase in total household income the lack of an effect on total household income suggests the return to the additional labour effort required for certified coffee production is not higher than in other activities questioning the benefits of certification for small scale producers

network effects and the dynamics of migration and inequality theory and evidence from mexico international migration is costly and initially only the middle class of the wealth distribution may have both the means and incentives to migrate which can increase inequality in the sending community however the migration networks formed lower the costs for future migrants which can in turn lower inequality this paper shows both theoretically and empirically that wealth has a nonlinear effect on migration and then examines the empirical evidence for an inverse u shaped relationship between emigration and inequality in rural sending communities in mexico after instrumenting we find that the overall impact of migration is to reduce inequality across communities with relatively high levels of past migration we also find some suggestive evidence for an inverse u shaped relationship among communities with a wider range of migration experiences

hyperinflation the exchange rate and endogenous money post world war i germany revisited abstract we re examine the interaction of domestic and external factors in the german hyperinflation by extending frenkel s monetary model of the exchange rate to incorporate 1 endogeneity of the money supply with respect to government debt expected inflation and money wages 2 the direct impact of exchange rate depreciation on the domestic price level and 3 endogenous wage determination four equation estimates support each extension of the monetary model it appears that government deficit finance the collapse of the exchange rate and the monetary transmission of the wage price spiral were all crucial contributors to the price explosion

the dynamics of chronic inflation in brazil 1968 1985 this article develops an error correction model with the aim of analyzing the behavior of prices during a period of chronic inflation in brazil the degree of inflationary inertia is estimated and tests for the importance of disequilibria in the domestic money foreign goods labor and domestic goods markets on inflation are carried out

an econometric model of the u s beekeeping industry this paper presents a dynamic econometric model of the u s beekeeping industry for policy analysis and economic projections data from 1952 to 1984 were used to estimate the model by three stage least squares the model indicates that when the federal price support for honey exceeded the market price the federal program had a significant impact on several sectors of the industry a comparison of beekeeper revenue consumer expenditures and federal government expenditures suggests the honey support program was an ineffective means of supporting honey prices from 1982 through 1984

the demand for money in brazil some further results abstract a recent paper by cardoso using the simple koyck adjustment mechanism has estimated a money demand equation for brazil the results are said to show among other things that the inflation rate does not play a significant role in the brazilian money demand function this paper re examines and expands on the money demand relationship in brazil finding that cardoso s estimated equations are inherently unstable using a less restrictive dynamic adjustment mechanism an alternative money demand relationship has been estimated for brazil which proves well fitting and structurally stable over time the inflation rates variable furthermore is found to exert a significant influence on real money demand in brazil in fact without such a variable our estimated money demand relationship appears toe misspecified and structurally unstable

school subsidies for the poor evaluating the mexican progresa poverty program abstract this paper evaluates how the progresa program which provides poor mothers in rural mexico with education grants has affected enrollment poor children who reside in communities randomly selected to participate in the initial phase of the progresa are compared to those who reside in other control communities pre program comparisons check the randomized design and double difference estimators of the program s effect on the treated are calculated by grade and sex probit models are also estimated for the probability that a child is enrolled controlling for additional characteristics of the child their parents local schools and community and for sample attrition to evaluate the sensitivity of the program estimates these estimates of program short run effects on enrollment are extrapolated to the lifetime schooling and the earnings of adults to approximate the internal rate of return on the public schooling subsidies as they increase expected private wages

an error correction approach to money demand the case of sudan abstract an empirical analysis of money demand behavior in sudan is presented based on the dynamic error correction model a theoretical basis for the model is offered which allows an explicit parameterized division of effects into long run influences short term adjustments and proportional equilibrium conditions we refute previous claims that income and price effects may be abnormally high in sudan in part by accounting for both foreign exchange and inflationary influences

the fable of the bees revisited causes and consequences of the u s honey program abstract in his 1973 paper steven cheung discredited the fable of the bees by demonstrating that markets for beekeeping services exist and function well although economists heeded cheung s lessons policy makers did not the honey program has operated for over 50 years supporting the price of honey through a variety of mechanisms its effects were minor before the 1980s but then became important with annual government expenditures near 100 million for several years reforms of the program in the late 1980s reduced its market effects and budget costs returning it to its original role as a minor commodity program although the 1996 farm bill formally eliminated the honey program it was reinstated in the 2002 farm bill we measure the historical welfare effects of the program during its various incarnations examine its frequently stated public interest rationale the encouragement of honeybee pollination and interpret its history in light of economic theories of regulation

rural nonfarm employment and income diversification in colombia abstract using data for rural households from colombia we find that off farm employment contributes a significant share 45 on average to household income but that the importance of off farm income and returns to household labor vary over the income distribution analysis reveals significant gains from specialization but for households able to specialize no systematic differences in returns to labor between farm and nonfarm sources we conclude that in colombia there is no conflict between development of the farm and the nonfarm sector but that to maximize gains from nonfarm development and reduce the scope for undesirable distributional consequences policies enabling households to specialize might be called for

the firm demand for liquid assets in an inflationary environment measures of inflation and the price level are added to the standard model of liquid asset demand and estimated with cross section data on brazilian manufacturing firms over a four year period characterized by substantial inflation annual rates of 19 23 34 and 35 results indicate that economies of scale exist in a model that is stable over time interest rates have a strong and elastic impact on liquid asset demand when inflation is explicitly controlled for although this result is not consistent across all subsets of data used the usual assumption of a unitary price level elasticity of liquid asset demand is rejected and firms appear to conserve on liquid asset holdings as the rate of inflation increases suggesting more careful management of payments flows some of these findings contradict those of ungar and zilberfarb 1980 there are also some difference in behaviour across ownership groups brazilian firms do not exhibit economies of scale while multinationals do and brazilian firms adjust ac

the demand for money in brazil what happened in the 1980s abstract some of cardoso s 1983 money demand specifications are used here the estimates are based on quarterly data for the period 1966 1985 it is shown that due to financial innovation the money demand function shifted downwards in the 1980 s also a comparison is made between the actual demand for money and that predicted by the model during the period in which the economic reforms of the cruzado plan were in force

global private regulation and value chain restructuring in indonesian smallholder coffee systems summary consumer concerns over the environmental and social conditions of coffee production have led to the proliferation of sustainability codes certification schemes and labeling claims in the sector this paper addresses how the global private regulation of ethical and environmental standards is having several implications for value chain structures and institutions in the smallholder coffee systems of indonesia global private regulation is driving structural changes in modes of farmer organization trader farmer relationships and is resulting in the increased upstream penetration of multinational trading companies into coffee producing areas across indonesia an unintended consequence of these changes in the future may be to increase transaction costs along the value chain and to exert an overall downward pressure on farm gate prices

the fable of the bees an economic investigation ever since a c pigou wrote his books on welfare a divergence between private and social costs has provided the main argument for instituting government action to correct allegedly inefficient market activities the analysis in such cases has been designed less to aid our understanding of how the economic system operates than to find flaws in it to justify policy recommendations both to illustrate the argument and to demonstrate the nature of the actual situation the quest has been for real world examples of such defects

a survey of the economics of fair trade fair trade has spread in developing countries as an initiative aimed at lifting poor smallholder farmers out of poverty by providing them with premium prices availability of credit and improved community development and social goods fair trade is also viewed as a niche market for high value products in a context of globalization and trade liberalization policies that affect smallholder farmers in developing countries the question of whether fair trade affects the welfare of rural farmers however is particularly contentious this paper provides a review of the fair trade literature both theoretical and empirical with a specific focus on the analysis of small scale producer s welfare in developing countries our review shows that while most empirical papers have focused on the impacts of fair trade on prices and income our review highlights the importance of limited market access and changes in productivity likewise little is known about the impacts of fair trade on labor markets and human capital investments persistent methodological challenges make it challenging however to assess the causal impact of this certification and labelling initiative

income strategies among rural households in mexico the role of off farm activities abstract off farm activities generate on average more than half of farm households incomes in the mexican ejido sector participation in these activities helps reduce poverty and contributes to greater equality in the distribution of income this paper analyzes the determinants of access to off farm sources of income across households we find that education plays a major role in accessing better remunerated nonagricultural employment adults of indigenous ethnic origin suffer from an educational lag and have less access to off farm nonagricultural employment than non indigenous adults at identical educational levels the regional availability of off farm employment strongly affects participation in addition women are differentially limited by distance to urban centers in their ability to gain off farm employment

intermediate monetary targets and macroeconomic fluctuations it is investigated whether the choice of intermediate target has altered macroeconomic fluctuations and whether the observed changes are consistent with predictions from economic theory since implications from the theoretical literature focus on the effects of structural disturbances an empirical analysis must identify these effects the structural vector autoregressive var technique estimates structural disturbances using restrictions from standard macroeconomic theory based on descriptions of actual targeting procedures by insiders to federal reserve policy decisions the intermediate target for the united states is identified as the interest rate from 1951 to 1969 and money from 1970 to 1986 var models are estimated over each subsample to assess whether the estimated structural disturbances cause endogenous variables to behave as economic theory predicts tests are also performed to assess whether or not the targeting rule affects the variance of endogenous variables attributable to structural sh

fair trade and free entry can a disequilibrium market serve as a development tool abstract the fair trade ft coffee initiative attempts to channel charity from consumers to poor producers via increased prices we show that the rules of the ft system permit this rent to be eliminated due to free entry and costly excess certification of output using data from an association of coffee cooperatives in central america we verify that expected producer benefits are close to 0 when we take into account the output that is certified but not sold as ft our results illustrate how free entry undermines the attempt at extending charity via a price distortion in an otherwise competitive market

asset substitution money demand and the inflation process in brazil various domestic financial assets in brazil have provided relatively liquid nonmonetary alternatives monthly money demand estimates which include domestic asset opportunity costs and take account of t bill repurchase agreements in a dynamic error correction model demonstrate the importance of domestic substitutes in explaining money holdings money demand appears responsive and stable moreover t bills and indexed bonds have acted as an alternative to central bank liabilities as a source of finance for government deficits evidence indicates that the initial financing of government deficits through bonds bills and other nonmonetary liabilities may explain why money lags price shocks rather than vice versa copyright 1989 by ohio state university press

mainstreaming fair trade coffee from partnership to traceability summary this article analyzes the recent growth of fair trade and the mainstreaming of this previously alternative arena focusing on coffee i identify a continuum of buyers ranging from mission driven enterprises that uphold alternative ideas and practices based on social ecological and place based commitments to quality driven firms that selectively foster fair trade conventions to ensure reliable supplies of excellent coffee to market driven corporations that largely pursue commercial industrial conventions rooted in price competition and product regulation using a commodity network approach my analysis illuminates the impacts of diverse buyer relations on producer groups and how relations are in some cases shifting from partnership to traceability

disentangling the effects of fair trade on the quality of malian cotton the increasing importance of premium segments and private labels raise skepticism about the ability of fair trade to help smallholders compete in high value added markets using panel data collected in mali this paper contributes to the debate by estimating the impact of fairtrade certification on the quality of malian cotton controlling for the nonrandom certification of producers results show a significant impact on the quality of cotton produced by both certified and geographically close noncertified growers via spillover effects the analysis suggests that contract farming enforced by third parties and demonstration effects foster the adoption of innovative agricultural practices

why do diplomas pay an expanded mincerian framework applied to mexico we compare four explanations for the value of diplomas each of which has implications for unemployment and wage variation amongst graduates most of which have not previously been tested for when seeking to explain the effects of diplomas we test for these implications using a refined econometric framework exploiting idiosyncrasies in mexican labour market and educational institutions premiums in mexico appear to result from diplomas tied to jobs with downwards rigid wages an uncommon but simple explanation the standard explanations including screening are not suggested by mexican data our results illuminate how labour markets segmented by diplomas clear this depends upon the nature of the labour market rigidities exactly as predicted by neoclassical theory

the economic sustainability of certified coffee recent evidence from mexico and peru consumers increasingly act on preferences for a more just and sustainable world by purchasing certified agricultural products using survey data from coffee growers in mexico and peru we explore the economic sustainability of certified coffee looking at conventional fair trade organic and rainforest alliance certified growers the analysis reveals that yields rather than price premiums are most important for increasing net cash returns for coffee growing households given the link between net returns and producer participation in certified coffee schemes the findings suggest that certification norms that permit improving yields are essential for improving grower welfare and attracting and maintaining growers

transforming or reproducing conventional socioeconomic relations introducing a regulationist framework for the assessment of fairtrade summary the certification based fair trade initiative is usually described as an alternative form of organizing production trade and consumption with the goal of advancing the situation of marginalized producers and workers while much of the fair trade literature has analyzed the system s direct impacts on its beneficiaries some strands have sought to determine its transformative potential vis a vis capitalist social relations in an attempt to contribute to the latter debate this paper introduces an analytical framework for the assessment of fairtrade built on the basis of the french regulation approach this perspective which focuses on the specific ways in which fairtrade structures and institutionalizes socioeconomic relations seeks to examine this system from a holistic perspective privileging the analysis of the qualitative changes it produces in economic institutions and structures this article presents the main assumptions and concepts developed by the regulation approach and proposes a case based research design that uses them to analyze how transformative fairtrade proves to be and the impacts it produces on specific economic sectors this methodological exposition is illustrated with examples from the case of fairtrade wine produced in argentina and consumed in the united kingdom

smallholder participation in contract farming comparative evidence from five countries summary supermarkets specialized wholesalers processors and agro exporters are transforming the marketing channels into which smallholder farmers sell produce in low income economies we develop a conceptual framework with which to study contracting between smallholders and a commodity processing firm we then synthesize results from empirical studies of contract farming arrangements in five countries ghana india madagascar mozambique and nicaragua the resulting meta narrative documents patterns of participation the welfare gains associated with participation reasons for nonparticipation the significant extent of contract noncompliance and the considerable dynamism of these value chains as farmers and firms enter and exit frequently

dynamic structural models and the high ination period in brazil modelling the monetary system in this paper we develop a linear structural dynamic econometric model for the high ination period in brazil the main goal is to obtain a parsimonious model that accounts for a complex dynamic present in the monetary system during the period describing therelationships among output ination rate interest rates and real money we start the analysis after the cruzado plan cast in 1986 following a progressive strategy in deriving the econometric model the results show that we can identify a long run money demand equation and the model describes parsimoniously and in detail the relationship among the variables despite all the instability present in the second half of the 1980 s in brazil with special attention to the role played by nominal wage ination in determining the dynamics observed in price ination

level playing fields and laissez faire postliberal development strategy in inegalitarian agrarian economies focusing on the rural sector in latin america this paper explores the microeconomic linkages between distribution and growth which drive the possible reproduction of rural poverty over time the result of this exploration is a neostructuralist perspective which argues that actually existing laissez faire agrarian economies do not present a level playing field and that low wealth farms face disadvantages which tend to reproduce or even deepen sectoral inequality the paper then tries to identify the sorts of public policy and collective action which might modify the nature of growth and distribution in post liberalization agrarian market economy

how much more do growers receive for fair trade organic coffee abstract i use a representative sample of coffee growing households in southern mexico to estimate the price premium and gross income gain from participating in fair trade organic markets through grower cooperatives for the 2004 2005 season ft organic growers received an average premium of 12 8 cents per pound yielding a gross income gain of 5 of total household income or about 26 dollars per household member the gain is net of the costs of cooperative participation but not of other costs incurred to become certified and suggests that price premiums alone have a limited potential to increase household returns from growing coffee more broadly speaking the finding raises questions about the persistence of substantial price premiums associated with social or environmental labeling initiatives

food standards certification and poverty among coffee farmers in uganda summary voluntary standards are gaining in importance in global markets for high value foods we analyze and compare impacts of three sustainability oriented standards fairtrade organic and utz on the livelihoods of smallholder coffee farmers in uganda using survey data and propensity score matching with multiple treatments we find that fairtrade certification increases household living standards by 30 and reduces the prevalence and depth of poverty for the other two certification schemes no significant impacts are found several factors that can explain differential impacts are discussed overly general statements about the effects of sustainability standards on smallholder livelihoods may be misleading

the demand for liquid assets a firm level analysis analysts have exerted considerable effort attempting to demonstrate that the firm demand for liquid assets or money conforms to microeconomic theory the theory itself is splintered along three lines of inquiry a keynesian version stressing the transaction and asset motives 28 33 35 an essentially quantity theory approach 19 6 and an approach which incorporates money into the firm s production function 22 31 7 29 the empirical work used to test these theoretical approaches has a common element a measure of the firm s scale is included usually sales or business receipts and generally a common flaw the use of aggregated data most studies have used industry level data because it is more readily available this forces the analyst to assume that firms within an industry are homogeneous while firms across industries are heterogeneous the authors can then use the typical firm as the unit of analysis the typical firm is a hypothetical construct whose characteristics are statistical means of all firms aggregated within the industrial category while this is a useful assumption the aggregation may hide the influence of the distribution of firms within the industry these distributional impacts may be significant if there are substantial economies of scale or if firm size influences such things as cash management practices and access to financial markets katsimbris and miller 15 have warned that the size distribution of firms within an industry may alter money demand the greater the inequality in sales the lower the industry s demand for money they find no support for the assumption of identical structural specification across industries these observations have been echoed by hunter 12 and by other work of katsimbris and miller 13 14 under such circumstances the use of industry average data may yield misleading conclusions on the firm demand for money any study of firm behavior in this area should at the very least control for industry some time ago vogel and maddala 33 called for empirical studies using firm level data a call which has gone largely unanswered this study attempts to fill this void by using a comprehensive set of firm level data over a five year period but we also attempt to answer several other questions does the presence of foreign ownership alter the firm s demand for liquid assets

in the market but not of it fair trade coffee and forest stewardship council certification as market based social change summary this paper discusses two well known market based social change initiatives fair trade coffee and forest stewardship council certification which harness market forces to pursue social and environmental objectives a serious challenge for both is to operate in the conventional market without undermining their original objectives a global commodity chain analysis approach is combined with insights from economic sociology embeddedness theory to explore the social cultural and organizational factors shaping the initiatives governance structures both initiatives are seen to move along opposite organizational trajectories but face similar pressures from conventional market logics practices and dominant actors a preliminary framework is proposed for comparative assessment focusing on distribution of benefits how conventional market institutions may be questioned and how internal governance manages diverse stakeholder interests and influence

a comparison among partial adjustment rational expectations and error correction estimates of the canadian demand for money starting from a dynamic optimization principle the currently most popular approaches to modelling money demand functions are derived the partial adjustment adaptive expectations rational expectations and error correction mechanism formulations are then estimated using a common data set the error correction mechanism equation is found to dominate the others either because their implicit restrictions are rejected rational expectations or by employing the encompassing principle partial adjustment adaptive expectations surprisingly all three forms have similar long run solutions since the short run dynamics differ substantially the results have important implications for the conduct of monetary policy

social learning and technology adoption the case of coffee pruning in peru a unique natural experiment involving a coffee pruning technology is used to study social learning the yield effects of pruning take two years to appear a characteristic that aids in identifying social learning apart from correlated unobservable variables that are a concern in the social learning and technology adoption literature panel data are employed that start with a private initiative which introduced systematic pruning in central peru and that contain the population of participating growers results show a jump of at least 0 15 in the probability of adoption two years after the first pruning in a grower s group jel classifications d83 q12

confronting the coffee crisis can fair trade organic and specialty coffees reduce small scale farmer vulnerability in northern nicaragua summary this paper links changing global coffee markets to opportunities and vulnerabilities for sustaining small scale farmer livelihoods in northern nicaragua changing governance structures corporate concentration oversupply interchangeable commodity grade beans and low farm gate prices characterize the crisis in conventional coffee markets in contrast certified fair trade and organic are two alternative forms of specialty coffee trade and production that may offer opportunities for small scale producers a research team surveyed 228 farmers to measure the impact of sales on organic and fair trade markets the results suggest that participation in organic and fair trade networks reduces farmers livelihood vulnerability 2004 elsevier ltd all rights reserved

diversification and labor market effects of the mexican coffee crisis this paper analyses how coffee producing households responded to the low coffee prices prevailing around 2003 we provide theory on differential responses in regions dedicated to coffee growing compared to more diversified or better accessible regions we show how labor market effects can explain why in the former regions value adding activities processing certification are undertaken while in the latter regions off farm activities are adopted farm size favors value adding activities as well as on farm diversification these findings call for policy responses to low prices that distinguish between specialized regions and diversified or well connected regions

identification and estimation of money demand in most natural sciences physics chemistry biology theories are validated by controlled experiment however in other natural sciences astronomy meteorology and in most social sciences including economics the data are characteristically generated not by experiment but by measurement of uncontrolled systems in economics theories take the form of restrictions on the models assumed to generate the data and statistical methods replace experimental controls in testing these restrictions and here is the difficulty in economics particularly macroeconomics the theory used to derive tests ordinarily does not generate a complete specification of which variables are to be held constant when statistical tests are performed on the relation between the dependent variable and the independent variables of primary interest accordingly in such cases there will be a set of often very different candidate regression based tests each of which has equal status with the others since each is based on a different projection of the same underlying multivariate model except in the unlikely event that the explanatory variables are mutually orthogonal the conditional regression coefficients which generally form the basis for the test statistic will depend on the conditioning set we conclude from this that if a theory which does not generate a complete specification of the regression test is nonetheless to have testable implications these implications must be robust over the permissible alternative specifications if the restrictions indicated by the theory are satisfied in some projections but not in others that have an equal claim to represent implications of the theory one cannot conclude that the theory has been confirmed the fact that the observable implications of valid theories must obtain over a broad but usually incompletely specified set of regressions rather than for a single regression introduces a large and unavoidable element of imprecision into hypothesis testing in macroeconomics generally it appears to be appropriate to weaken the statistical criterion for rejecting theories consider for example the theory of money demand which will engage our attention in this paper the tobin baumol square root formula implies that the elasticity of money demand with respect to the interest rate is exactly one half but which interest rate should wealth be held constant inflation in view of such uncertainties it would be inappropriate to insist in a literal minded fashion on rejecting the tobin baumol model if in some regression the measured interest elasticity differed from one half by more than two standard deviations and only then obviously a more flexible approach is called for the practice has been to conclude that the statistical evidence is consistent with the tobin baumol model as long as the interest rate coefficient is negative if it is negative and significant or negative and insignificantly different from minus one half that would provide somewhat stronger confirmation but a positive coefficient particularly a significantly positive coefficient would be viewed as raising questions about the validity of the theory in macroeconomics generally as in the money demand application the typical response to specification uncertainty has been to regard a theory as supported if the signs of the estimated coefficients agree with those expected from theory and as disconfirmed otherwise there is no theoretical justification for this procedure but it seems to be a reasonable course to follow the point that economic theory ordinarily generates incompletely specified statistical university of california santa barbara we have received helpful comments from andrew abel robert clower michael darby robert engle stephen goldfeld david laidler edward leamer robert lucas frederic mishkin and edward prescott thomas hall provided able research assistance

international migration self selection and the distribution of wages evidence from mexico and the united states we use the 1990 and 2000 mexican and u s population censuses to test borjas s negative selection hypothesis that the less skilled are those most likely to migrate from countries with high skill premia earnings inequality to countries with low skill premia earnings inequality we find that mexican immigrants in the united states are more educated than nonmigrants in mexico and were mexican immigrants to be paid according to current skill prices in mexico they would be concentrated in the middle of mexico s wage distribution these results are inconsistent with the negative selection hypothesis and instead suggest that there is intermediate selection of immigrants from mexico

international evidence on misspecification of the standard money demand equation abstract this paper tests the proposition that the interest rate in the standard money demand equation acts as a proxy for the expected change in interest rates if this is true the interest elasticity in the standard equation will depend on the expectations process for interest rates using cross country data we find that there does exist a relationship between the observed interest elasticity in the standard equation and the predictability of future interest rates from current interest rates

changing asset endowments and smallholder participation in higher value markets evidence from certified coffee producers in nicaragua this paper examines the capacities of smallholders in nicaragua to exploit new linkages to certified coffee markets following the coffee crisis data on livelihood assets were collected from 292 households which were clustered to test how differences in outcomes asset building reflect variations in initial asset endowments the results suggest that most households built particular elements of their asset base and increased their resilience to future shocks however households struggled to make effective use of the gains for intensifying their livelihoods of the least endowed households few made investments in the scale or productivity of coffee and most continued to depend heavily on subsistence production and seasonal off farm income for survival in conclusion improved market access alone even under relatively favorable market conditions and with considerable external support will have uncertain impacts on rural poverty if the underlying constraints on household assets and investments are not addressed concurrently
