do vietnamese upland farmers benefit from high world market prices for maize for rural households in the north of vietnam maize cropping is the main source of income in the face of the world market price increases of the recent past we analyze the regional marketing chain of this commodity qualitatively and econometrically investigating to what extent smallholder farmers in developing countries are affected by international price movements vietnamese maize markets are found to be well integrated recent price hikes have fully transmitted along the regional supply chain so that farmers profited nevertheless adverse factors such as increasing input prices have neutralized these benefits resulting in a decline in real income of smallholders

credit market constraints consumption smoothing and the accumulation of durable production assets in low income countries investments in bullocks in india in this paper we formulate and estimate a finite horizon structural dynamic model of agricultural investment behavior that incorporates the major features of low income agricultural environments income uncertainty constraints on borrowing and rental markets and the use of investment assets to generate income and smooth consumption the model is fit to longitudinal indian household data on farm profits bullock stocks and pump sets the estimated structural parameters are used to assess the effects on the life cycle accumulation of bullocks agricultural profits and welfare associated with complete markets and bullock liquidity and with second best policies that provide assured sources of income to farmers and weather insurance

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

information disclosure policies evidence from the electricity industry i introduction developed nations environmental policies have evolved substantially in the past several decades early pollution control programs involved command and control approaches policies then frequently included pollution charges tradable permits and other market based instruments most recently a third wave of environmental policy has emerged that emphasizes information provision as an integral part of the risk mitigation strategy here government regulation is replaced or augmented by publicly provided information presumed to assist more cost effective private market and legal forces common examples include the toxics release inventory lead paint disclosures drinking water quality notices and eco labels the empirical effects of such programs however remain largely undetermined this paper examines the impact of a prominent mandatory disclosure program on the fuel mix percentages of large electric utility corporations the prominence of mandatory information policies is not restricted to environmental arenas for example developed countries equity markets generally require firm level financial information provision in many countries agricultural goods require country of origin and other health labels domestic colleges and universities are required by law to inform current and prospective students of crime statistics equity data and performance metrics even significant medical errors must now be disclosed to the community there are several potential advantages of information provision policies and theory suggests that disclosure programs may effectively achieve their goals healy and palepu 2001 provided a survey of the evidence in capital markets brouhle and khanna 2007 demonstrated that information provision can improve product quality in the environmental area kennedy laplante and maxwell 1994 arora and gangopadhyay 1995 maxwell lyon and hackett 2000 kirchhoff 2000 and khanna 2001 showed that the provision of information about pollution may correct a market failure improve performance and enhance welfare despite the literature s theoretical findings the empirical effects of disclosure programs remain inconclusive early studies of securities regulation found mixed results see stigler 1964 robbins and werner 1964 and benston 1973 a more recent literature suggested that disclosure programs in financial markets can achieve their desired effects la porta and lopez de silanes 2006 and greenstone oyer and vissing jorensen 2006 found that both market size and market returns were positively influenced by mandatory disclosure programs in product quality settings chipty and witte 1998 established that resource and referral agencies significantly influenced childcare prices but had no impact on the quality of care in contrast jin and leslie 2003 found that mandatory hygiene grade cards positively affected restaurant quality and health outcomes studies of environmental performance yielded similarly mixed results desvousges smith and rink 1992 found that information based programs influenced attitudes favorable to radon testing but testing itself only increased when mass media dissemination was coupled with community based implementation programs konar and cohen 1997 and khanna quimio and bojilova 1998 found that stock movements associated with toxics release inventory tri announcements led to increased abatement and reduced emissions however bui 2005 found that the declines in emissions after tri reporting events may have been attributable to regulation rather than investor pressure bennear and olmstead 2006 found that drinking water quality notices lowered violations for some systems but not others this paper is the first empirical economic study of the impacts of mandatory information provision in the electric utility industry the disclosure programs considered here differ significantly from the tri information programs examined previously

distributional effects of wto agricultural reforms in rich and poor countries rich countries agricultural trade policies are the battleground on which the future of the wto s troubled doha round will be determined subject to widespread criticism they nonetheless appear to be almost immune to serious reform and one of their most common defenses is that they protect poor farmers the authors findings reject this claim the analysis uses detailed data on farm incomes to show that major commodity programs are highly regressive in the united states and that the only serious losses under trade reform are among large wealthy farmers in a few heavily protected subsectors in contrast analysis using household data from 15 developing countries indicates that reforming rich countries agricultural trade policies would lift large numbers of developing country farm households out of poverty in the majority of cases these gains are not outweighed by the poverty increasing effects of higher food prices among other households agricultural reforms that appear feasible even under an ambitious doha round achieve only a fraction of the benefits for developing countries that full liberalization promises but protect u s large farms from most of the rigors of adjustment finally the analysis indicates that maximal trade led poverty reductions occur when developing countries participate more fully in agricultural trade liberalization

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

openness and wage inequality in developing countries the latin american challenge to east asian conventional wisdom the experience of east asia in the 1960s and 1970s supports the theory that greater openness to trade tends to narrow the wage gap between skilled and unskilled workers in developing countries in latin america since the mid 1980s however increased openness has widened wage differentials this conflict of evidence is probably not the result of differences between east asia and latin america instead the conflict is probably the result of differences between the 1960s and the 1980s specifically the entry of china into the world market and perhaps the advent of new technology biased against unskilled workers

health behavior health knowledge and schooling the positive correlation between schooling and good health is well documented one explanation is that schooling helps people choose healthier life styles by improving their knowledge of the relationship between health behaviors and health outcomes that is schooling improves the household s allocative efficiency in producing health this empirical study uses direct measures of health knowledge to test this explanation part of the relationship between schooling and the consumption of cigarettes alcohol and exercise is explained by differences in health knowledge however most of schooling s effects on health behavior remain after differences in knowledge are controlled for

the comparative politics of corruption accounting for the east asian paradox in empirical studies of corruption growth and investment abstract numerous empirical studies demonstrate that corruption reduces investment and or slows growth but how robust are these relationships this question is answered by conducting a series of crosscountry regression tests using four different corruption datasets we find that corruption slows growth and or reduces investment in most developing countries particularly small developing countries but increases growth in the large east asian newly industrializing economies the latter finding provides solid empirical support to a country case literature that explains the east asian paradox the combination of high corruption and high growth in terms of stable and mutually beneficial exchanges of government promotional privileges for bribes and kickbacks

consumer health information and the demand for medical care this paper is an empirical investigation of consumer health information using a new direct measure of information the econometric approach treats both information and physician visits as endogenous variables when estimating the demand for medical care the results show that information increases the probability that a consumer uses medical care but that conditional on use the quantity of care consumed is not related to information the results contradict specific implications of models where physicians can create or induce demand for their own services several results suggest that poorly informed consumers tend to underestimate the productivity of medical care in treating illness copyright 1990 by mit press

efficiency analysis of german electricity distribution utilities non parametric and parametric tests this study applies non parametric and parametric tests to assess the efficiency of electricity distribution companies in germany traditional issues in electricity sector benchmarking are addressed such as the role of scale effects and optimal utility size as well as new evidence specific to the situation in germany labour capital and peak load capacity are used as inputs and units sold and the number of customers as output the data cover 307 out of 553 german electricity distribution utilities a data envelopment analysis dea is applied with constant returns to scale crs as the main productivity analysis technique whereas stochastic frontier analysis sfa with distance function is the verification method the results suggest that returns to scale play but a minor role only very small utilities have a significant cost advantage low customer density is found to affect the efficiency score significantly in particular in the lower third of all observations surprisingly east german utiliti

trade liberalisation and poverty what are the links this paper asks whether a developing country s own trade liberalisation could translate into increased poverty and what information would be required to identify whether it will do so it plots the channels through which such effects might operate identifying the static effects via four broad groups of institutions households distribution channels factor markets and government and the dynamic issues of volatility long term economic growth and short term adjustment stresses an increase in the price of something a household sells labour good service increases its welfare thus the paper first explores the likely effects of trade liberalisation on the prices of goods and services taking into account the distribution sector also critical is whether trade reform creates or destroys markets trade reform is also likely to affects factor prices of which the wages of the unskilled is the most important for poverty purposes if reform boosts the demand for labour intensive products it boosts the demand for labour and wages and or employment will increase however not all developing countries are relatively abundant in unskilled labour and trade can boost demand for semi skilled rather than unskilled labour hence poverty alleviation is not guaranteed trade reform can affect tariff revenue but much less frequently and adversely than is popularly imagined even if it does it is a political decision not a law of nature that the poor should suffer the resulting new taxes or cuts in government expenditure opening up the economy can reduce risk and variability because world markets are usually more stable than domestic ones but sometimes it will increase them because stabilisation schemes are undermined or because residents switch to riskier activities the non poor can generally tide themselves over adjustment shocks from a liberalisation so public policy should focus on whether the initially poor and near temporary setbacks the key to sustained poverty alleviation is economic growth there is little reason to fear that growth will not boost the incomes of the poor similarly while the argument that openness stimulates long run growth has still not been completely proven there is every presumption that it will

modelling labour market adjustment to trade liberalisation in an industrialising economy this paper investigates labour market responses to trade liberalisation in an industrialising country short and long run responses of employment and wages are examined using a specific factor trade model which underpins the empirical work employment and wage equations are estimated using dynamic panel techniques for importable and exportable sectors in mauritius and for a period covering both the pre and post liberalisation regimes the empirical testing finds some support for the theoretical predictions of differential responses between sectors increases in female participation however appear to have dampened the adjustment burdens of liberalisation on importables there is relatively little evidence available about the effects of trade induced shifts in the composition of demand on inter industry employment and wage levels in developing countries analyses of the factor content of imports and exports suggest that a shift from import substitution is to export promotion ep policies will typically in the case of a developing country expand the more labour intensive industries increase labour demand overall and drive up real wages in the long run but trade liberalisation and increased foreign competition may not only affect the composition of the tradeables goods sector i e the distribution between importables and exportables they may also affect both the efficiency with which all firms use factors including labour and the distribution of output within a sector between more and less efficient firms thus the net long run effects of trade liberalisation on employment will depend upon the balance of structural and efficiency effects which cannot be identified from analyses of the composition of trade alone further we must also recognise that the short and long run effects of trade liberalisation on employment and wages may diverge the divergence depending on the degree of factor mobility and the competitiveness of labour markets the aim of this paper is to model labour market adjustment to trade liberalisation in an industrialisingz country it will do so using panel data evidence for mauritius an economy that has undergone significant trade liberalisation and transformation during the 1980s indeed mauritius is viewed simultaneously as a successful liberaliser and an economy with extensive government intervention in the labour market it provides a valuable test base

a theory of impact philanthropy this article develops a new model of altruism called impact philanthropy an impact philanthropist is someone who wants to personally make a difference while that motive is straightforward its logical implications are significantly different from other models of philanthropy for example the contributions of other donors can reduce an impact philanthropist s charitable fulfillment as a result cooperation among impact philanthropists can reduce aggregate giving in addition impact philanthropy can lead to a codependent relationship between givers and receivers in which both benefit from the other finally the model suggests a conflict between charitable organizations and its donors concerning the allocation of charitable gifts in particular a charitable organization prefers to spread a donor s contribution across many goods whereas a donor prefers to target his or her contribution at a specific good d 2003 elsevier b v all rights reserved

corruption and fast change summary the article elucidates conceptual issues that arise for the study of corruption when several coexisting contradictory norms for allocating different modes of transactions across society exist one important reason for their coexistence is fast change of the institutional rules that allocates transactions across transactional modes two cases are explored and studied 1 transition from a family based to a modern normative grid and 2 transition from a socialist to a market based economy corruption is regarded as illegitimate intrusions of market or family modes of transaction into political or bureaucratic fields

reducing the size of the public sector workforce institutional constraints and human consequences in guinea public sector employment reduction programmes have become an important component of economic reform efforts in sub saharan africa this article examines the fiscal institutional and human consequences of an employment reduction programme in the west african state of guinea while fiscal benefits appear to have been marginal and compensation schemes well targeted the human costs of the programme were significant due to long spells of unemployment among retrenched workers

information as regulation the effect of community right to know laws on toxic emissions abstract there is growing academic and policy level interest in the use of information as quasi regulatory mechanisms such as toxic release inventory tri and green labels mandatory disclosure requirements have been touted as market based incentives that may affect firm behavior we provide new evidence on the effectiveness of disclosure requirements by examining firm behavior in response to disclosures of tri emissions we find that firms with the largest stock price decline on the day this information became public subsequently reduced emissions more than their industry peers this is consistent with the view that financial markets may provide strong incentives for firms to change their environmental behavior

the link between increased trade openness and the terms of trade an empirical investigation abstract despite the fairly widespread move towards more open trade policies in developing countries relatively little attention has been paid to the effect of these policies on the terms of trade using a large sample of countries this paper tries to assess empirically the validity of the small country assumption which underlies the washington consensus on development strategies our evidence suggests that there is a sizable group of countries ldcs and non ldcs for which the assumption of exogenous traded goods prices can be rejected one implication is that terms of trade considerations should be included in the assessment of trade liberalization policies these effects might rise considerably when several countries liberalize simultaneously

spice price spikes simulating impacts of saffron price volatility in a gendered local economy wide model summary access to international markets provides smallholders with unprecedented opportunities but also exposes them to world market whims we use a local economy wide impact evaluation lewie model to analyze how the recent global saffron price variability affected morocco s taliouine taznakht region a specialized agro export economy with a stark gender division of labor prices of saffron increased by 71 per year over the 2007 09 period before falling quickly back to their trend our modeling approach allows us to simulate such shocks and evaluate impacts not only on producers but also on the local economies around them in our simulations positive price shocks and increases in productivity both cause large reallocations of labor resources particularly for female workers at harvest time we use monte carlo simulations to evaluate how saffron price variance affects the economy female wage income is especially sensitive to global price variability a 100 increase in saffron price variance leads to 133 increase in female wage income variance but only 36 for males accounting for general equilibrium effects is critical for understanding the ramifications of exposure to export price volatility in poor economies

agricultural trade liberalization and poverty dynamics in three developing countries many developing countries implemented sweeping agricultural reforms over the last decade reforms have included the removal of quotas and price controls changes in international trade barriers and the commercialization and privatization of state marketing boards for key crops these reforms have often generated intense criticism from groups claiming that they hurt poor farmers and poor households this concern has generated an extensive literature on the economics of agricultural trade reform in developing countries much of which has focused on explaining the large variations in supply response across countries regions and households e g key sadoulet and de janvry in addition anumber of papers have attempted to simulate the impact on poverty using household survey data and actual or predicted price changes e g chen and ravallion however in many cases the true impact of agricultural reform is difficult to determine in part this is because the analysis is based upon household surveys at a single point in time so that the final post adjustment consequences upon individual households are unknown also even where observations are available over time it has so far proved difficult to disentangle the effects of trade and agricultural liberalization from other contemporary shocks this abstract was borrowed from another version of this item

the effect of information on product quality evidence from restaurant hygiene grade cards this study examines the effect of an increase in product quality information to consumers on e rms choices of product quality in 1998 los angeles county introduced hygiene quality grade cards to be displayed in restaurant windows we show that the grade cards cause i restaurant health inspection scores to increase ii consumer demand to become sensitive to changes in restaurants hygiene quality and iii the number of foodborne illness hospitalizations to decrease we also provide evidence that this improvement in health outcomes is not fully explained by consumers substituting from poor hygiene restaurants to good hygiene restaurants these results imply that the grade cards cause restaurants to make hygiene quality improvements

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 illusion of sustainability this brief summarizes the results of a gender impact evaluation study entitled the illusion of sustainability conducted during the time period 1998 to 2001 in kenya the study observed that deworming is a public good since much of its social benefit comes through reduced disease transmission people were less likely to take deworming if their direct first order or indirect second order social contacts were exposed to deworming the introduction of a small fee for deworming drugs led to an 80 percent reduction in treatment rates take up was not sensitive to the exact price level suggesting that it is particularly counter productive to charge small positive prices for the treatment of infectious diseases an intensive school health education had no impact on worm prevention funding for the study derived from world bank nih fogarty international center berkeley center for health research

operational performance of the bangladesh rural electrification program and its determinants with a focus on political interference abstract this article tries to quantitatively capture the effect of political intervention on the operational performance of the bangladesh rural electrification program rep firstly efficiency changes over the last 15 years of rural electric cooperatives in the rep are examined using data envelopment analysis dea then the critical determinants of the efficiency changes including political indicator are identified with an application of the tobit model results from the dea analysis show the overall efficiency score on a scale of zero to one changes in the 0 856 0 929 range in 15 years with two turnaround points in 1996 and 2001 these are the years that the national elections were held the results also find a gap between the efficient rural electric cooperatives and the inefficient rural electric cooperatives the results of the tobit model imply that political power has a negative impact on efficiency

toxics release information a policy tool for environmental protection abstract this study examines investor reactions to the repeated public disclosure of environmental information about firms in the chemical industry and the effectiveness of this information as a decentralized mechanism for deterring their pollution by allowing investors to benchmark the performance of firms repeated provision of the toxics release inventory led firms to incur statistically significant negative stock market returns during the one day period following the disclosure of that information in the years 1990 1994 these losses had a significant negative impact on subsequent on site toxic releases and a significant positive impact on wastes transferred off site but their impact on total toxic wastes generated by these firms is negligible

expected poverty under risk induced welfare variability two of the most widely accepted stylised facts about agriculture in south asia sub saharan africa and elsewhere are that income is highly uncertain from one year to another and that deep and widespread poverty exists and yet there has been very little analysis of the joint problems of poverty and risk this paper offers a methodological approach to the issue of how risk affects poverty and applies it to household level data for dry areas of rural india the following questions are addressed under what conditions can one expect an increase in the riskiness of an income or consumption stream to increase poverty how should one measure the contribution of risk to poverty and what long term benefits in terms of reduced poverty can be expected from policies aimed at stabilising incomes of the poor such policies have been widely discussed in the indian subcontinent of late and their effect on rural

global policy of rural electrification energy poverty and lack of electricity in the rural area exacerbate the poverty of the developing countries the sustainable renewable technologies can be considered as efficient tools to reduce energy poverty whenever they are conducted based on an appropriate policy electricity can improve the human s lifestyle by increasing the level of health education welfare and technology currently sub sahara africa with only 14 2 of rural electrification has the first rank in the world with lowest access to electricity in that region around 585 million citizens has almost no access to electricity the present study focuses on the general global policies to electrify the rural areas in this regard variety of plans and programs conducted by governmental and private institutes are investigated in the year 2011 the international energy agency iea has developed three global strategies based on the world energy market that defines the overall world energy approach in the present work different technologies for rural electrification are taken into account in two major categories of grid connected and off grid systems furthermore based on sustainable development with emphasis on environmental consideration the feasibility of electrification by using different types of renewable energies such as solar biomass hydro wind and wave have been studied despite reliability of grid connection results indicate that renewable energy sources are the best choice especially in areas far from grid connections challenges between financial institutes and executive agencies result in resource management and technology development in order to overcome existing barriers and issues

underdevelopment and the economics of corruption a game theory approach abstract previous attempts to treat corruption are surveyed critically a game theory approach is preferred on the grounds that it can most effectively explain the basis for decisions of reasonable men to be corrupt a simple model is presented showing how bribery might be a dominant strategy a prisoner s dilemma type of situation emerges with the added complication that the judge and jailer may be corrupt other conclusions are that one official will not accept bribes from more than one firm it is impossible to predict which firm will win the contract no obvious solution emerges and legal remedies are discounted this paper then reviews the principal general equilibrium effects and concludes that their likely effect on economic development is negative

trade liberalisation poverty and inequality in vietnam a quantile regression approach abstractthis study examines the effects of trade liberalisation on rural household welfare poverty and inequality in vietnam with the use of multiple estimation strategies including the panel quantile regression approach based on canay s two step estimator taking account of the multi faceted nature of trade liberalisation we consider a set of household level trade related variables including employment in export import competing and manufacturing sectors a unique panel data set is constructed from the vietnam household living standards surveys conducted in 2002 2004 and 2006 we find that employment in trade related sectors contributes significantly to rural household welfare moreover the effects of trade related employment on welfare are heterogeneous across the welfare income distribution in that trade related employment sectors have different influences on different groups quantiles of households

fairtrade and labour markets in ethiopia and uganda abstractdrawing on four years of fieldwork in ethiopia and uganda this paper addresses gaps in knowledge about the mechanisms linking agricultural exports with poverty reduction the functioning of rural labour markets and the relevance to the lives of the poorest people of fairtrade statistical analysis of survey evidence complemented by qualitative research highlights the relatively poor payment and non pay working conditions of those employed in research sites dominated by fairtrade producer organisations we conclude that fairtrade is not an effective way to improve the welfare of the poorest rural people

more information is not always better the case of voluntary provision of environmental quality this paper adds to the literature on the voluntary provision of public goods by showing that the warm glow that individuals gain depends on the perceived relative effectiveness of contributions we use a new survey on pro environment behaviors attitudes and knowledge and find that individuals act in accordance with their beliefs regardless of whether or not these beliefs are accurate and engage more frequently in activities that have a higher perceived impact on environmental quality we find that low provision of the public good is greater among people who believe they cannot do much for the environment and do not consider themselves environmentalists

corruption and inefficiency theory and evidence from electric utilities we investigate the determinants of the efficiency of firms with a focus on the role of corruption we construct a simple theoretical model where corruption increases factor requirements of firms because it diverts managerial effort away from factor coordination we then exploit a unique dataset comprising firm level information on 80 electricity distribution firms from 13 latin american countries for the years 1994 to 2001 as predicted by the model we find that more corruption in the country is strongly associated with more inefficient firms in the sense that they employ more inputs to produce a given level of output the economic magnitude of the effects is large the results hold both in models with country and firm fixed effects the results survive several robustness checks including different measures of output and efficiency and instrumenting for corruption other elements associated with inefficiency are public ownership inflation and lack of law and order but corruption appears to play a separate and more robust role

risk taking behavior in the presence of nonconvex asset dynamics a growing literature on poverty traps emphasizes the links between multiple equilibria and risk avoidance however multiple equilibria may also foster risk taking behavior by some poor people we illustrate this idea with a simple analytical model in which people with different wealth and ability endowments make investment and risky activity choices in the presence of known nonconvex asset dynamics this model underscores a crucial distinction between familiar static concepts of risk aversion and forward looking dynamic risk responses to nonconvex asset dynamics even when unobservable preferences exhibit decreasing absolute risk aversion observed behavior may suggest that risk aversion actually increases with wealth near perceived dynamic asset thresholds although high ability individuals are not immune from poverty traps they can leverage their capital endowments more effectively than lower ability types and are therefore less likely to take seemingly excessive risks in general linkages between behavioral responses and wealth dynamics often seem to run in both directions both theoretical and empirical poverty trap research could benefit from making this two way linkage more explicit jel d81 o12 d90

household responses to economic and demographic shocks marginal logit analysis using indonesian data abstract we analyse the responses of indonesian households to demographic and economic shocks and examine how these responses vary in relation to the household s permanent income and the extent to which the shock is common across the community households respond in different ways to demographic and economic shocks economic shocks are more likely to result in a labour supply response from the household and this probability is further increased if the shock is common for rural households use of savings increases with permanent income the article also examines the role of the interviewer in influencing survey responses

impacts of world prices transmission to domestic rice markets in rural iran abstract this paper attempts to assess the degree to which iranian rural households have responded to the change in price of imported rice due to exchange rate unification and to examine the extent to which the policy has affected the economic welfare of various household income groups particularly the poor utilizing samples of 2472 households selected from national expenditure survey data of 2002 and 2003 armington and pass through elasticities were calculated as two measures of substitutability and are discussed separately for each household group in these areas the findings of this study indicate that domestic rice prices are associated differently with imported rice prices among the households however a price increase in imported rice that is mainly consumed by the poor worsens their position much more severely than for the rich people who mainly prefer domestic rice the findings contribute to the understanding of how price changes resulting from trade liberalization may affect various groups of households and the ways they respond to such changes in prices

households vulnerability from trade in vietnam abstract this paper assesses vulnerability from trade in vietnam by presenting an extended version of ligon and schechter s 2003 vulnerability as low expected utility veu measure it uses the vietnam household living standard surveys vhlss panel data covering the period 2002 06 the empirical results show that risk induced vulnerability and heterogeneity in trade exposure matter in determining household overall vulnerability and that this is not linked to the actual manifestation of shocks although it does not represent by any means an argument against free trade this work is relevant for policymaking since it contributes to deepen our knowledge on the subtle links between trade openness and vulnerability and informs us about suitable instruments to accompany it

the simultaneous evolution of growth and inequality research on inequality and growth can be divided into two strands one deriving from kuznets and lewis has tried to identify a mechanistic relationship between growth or level of income and inequality the other has tried to find causal explanations of growth and inequality treating each independently in this paper we draw from both strands to test whether growth and inequality are the joint outcomes of other variables and processes we find that simultaneous examination of growth and inequality yields significantly different results and has different consequences for policy from previous independent studies the empirical literature on growth and inequality can be divided into two broad strands one following the pioneering work of kuznets and lewis is motivated by the pessimistic conjecture that the process of growth and development somehow requires increasing inequality at least in the early stages this has led to many efforts to identify a mechanical relationship between the level of development and inequality anand and kanbur 1993 or to determine whether faster growth requires higher or lower inequality the second strand has sought to identify the causal factors influencing the evolution of growth and inequality independently this research has looked either at growth for example barro and sala i martin 1995 or at inequality li et al 1997 but has not tried to identify those factors that might simultaneously influence both growth and inequality 2 thus the literature that looks simultaneously at growth and inequality descending most notably from kuznets 1955 relates them in a mechanistic manner that ignores or minimises the role of other causal factors including policy while the literature that incorporates other causal factors including policies looks independently at growth and inequality neither approach is particularly convincing from a theoretical standpoint the evolution of growth and inequality must surely be the outcome of similar processes in addition neither approach is particularly useful for the policy maker who needs to balance the impact of policies on both growth and distribution in this paper we investigate whether growth and inequality are simultaneously determined and if so whether or not they are subject to

opening of china s trade labour market reform and impact on rural wages government policy in china supports urban wages at the expense of returns to farm labour a model is developed to estimate how wto accession and complementary labour market reform will influence factor returns in china with wto membership a larger cut in manufacturing tariffs compared to agriculture will improve agriculture s terms of trade and will raise the agricultural wage complementary labour market reforms will further boost farm wages as labour exits agriculture in large numbers we estimate that wto membership and complementary labour market reforms will result in a decline in the agricultural labour force by about 25 per cent

research and development aspects on decentralized electrification options for rural household abstract low income households living in the rural areas suffer from energy poverty and lack of human and economic development currently many governments of less developed countries are committed in improving access to electricity the same commitment should be adapted globally as part of human right because providing electricity access to low income households improves health and education generates income increases productivity reduces inequality and enhances the quality of life rural electrification is a complicated issue because of user affordability rural inaccessibility and remoteness low population densities and dispersed households low project profitability fiscal deficit scarcity of energy resources population growth lack of professionalism and over dependence on subsidies the demand for electrification cannot be accomplished because of the increasing gap between rural electrification rate and population growth therefore this review aims to study various decentralized household sized energy technologies available in rural areas such as battery diesel generator pedal generator pico hydro photovoltaic pv solar home system and wind preference for one of the options depends on energy source availability economic feasibility rural economic development disposal of residues nature of end user application and government programs and policies pico hydro is the preferred electricity generation source in most rural households followed by wind pv and diesel generators this paper concurs that households in rural areas will be able to afford for electricity access if the payment schedule of the electrification cost is extended and interest rates and taxes if any are dropped

poverty dynamics in brazilian metropolitan areas an analysis based on hulme and shepherd s categorization 2002 2011 abstract ever more sophisticated studies on the methodological approach and the conceptual scope of poverty have led to a consensus among scholars on the dynamic characteristic of this phenomenon in other words the existence of an in and out of privation movement of individuals and families within this context hulme and shepherd 2003 defined five groups according to the location of the punctual and average indicators of poverty vis a vis the poverty line this paper s objective is to adapt this typology to brazil using pme monthly job survey micro data for the 2002 2011 timeframe and the six brazilian metropolitan regions covered by pme as well as by estimating a multinomial logit investigate which family characteristics relate to a greater or lesser chance of belonging to each of the chronic and transitory poverty categories categorization allows observation that despite a sweeping across the board decline in the percentage of families in all poverty categories in the past decade those families always or usually poor display demographic socioeconomic access to and insertion into the labor market categories which differ from families in transitory poverty or classified as never poor moreover northeastern metropolitan regions salvador and recife have higher percentages of chronic or transitory poverty multinomial logit estimates make it possible to verify that families whose members have completed secondary schooling or college or hold a higher qualified occupation stand lesser chances of entering into or remaining in poverty results call for differentiating among poor families as they enter into or leave poverty which is tantamount to saying that the dynamics of poverty must be taken into account as public policies are drawn up

a matter of relational style loan officer consistency and exchange continuity in microfinance social scientists have long considered what mechanisms underlie repeated exchange three mechanisms have garnered the majority of this attention formal contracts relational contracts and relationally embedded social ties although each mechanism has its virtues all three exhibit a common limitation an inability to fully explain the continuation and stability of intertemporal exchange between individuals and organizations in the face of change drawing on extensive quantitative data on approximately 450 000 microfinance loans made by a microfinance institution in mexico from 2004 to 2008 that include random assignment of loan officers this research proposes the concept of relational styles to help explain how repeated exchange is possible in the face of personnel change we define relational styles as systematically reoccurring patterns of interaction employed by social actors within and across exchange relationships in this paper between microfinance clients and loan officers we show that relati
