poverty transition in rural vietnam the role of migration and remittances abstractthis study combines insights of the new economics of labour migration with the asset based approach to welfare dynamics using panel household data from vietnam this method allows us to determine whether poverty transitions induced by remittances are actually structural that is based on asset growth and therefore long term or stochastic that is based only on short term increases in income which implies a risk of falling back into poverty to control for endogeneity of remittances we use household fixed effects and instrumental variables estimation the paper shows that remittances have a positive impact on asset growth and that the impact differs with welfare status and ethnicity

nominal and real wage cyclicality during the interwar period although there have been numerous attempts to study the cyclicality of real wages in the u s no consensus has formed as to the implications of the various findings for business cycle theory this paper will demonstrate that separating the real wage into its nominal and price level components can shed new light on the interwar u s labor market more specifically we will show that an evolution from a relatively laissez faire labor market during the 1920s to a more highly regulated labor market during the 1930s may have resulted in a more countercyclical real wage rate if we could be certain that equilibrium business cycle models provided the correct specification of the labor market then interpretation of real wage cyclicality would be relatively straightforward during periods dominated by labor demand shocks real wages would move procyclically and during periods dominated by labor supply shocks real wages would move countercyclically in a disequilibrium model context however interpretation of real wage cyclicality is much more problematic if nominal wages are sticky then unanticipated price level changes can induce countercyclical real wage movements that mimic the real wage movements generated by shifts in the supply of labor perhaps the most famous and controversial example occurred during the first three years of the great depression when a massive decline in hours worked and production was associated with a sharp increase in the aggregate real wage rate see figure 1 even greater complexity results from governmental attempts to influence the aggregate nominal wage policies that attempt to artificially change the nominal wage rate can result in either procyclical or countercyclical real wages depending on whether the direct impact of changes in the price of labor on the quantity of labor demanded outweighs the impact of wage changes on aggregate demand and output separating the aggregate real wage rate into its nominal and price level components will allow us to discriminate between these two hypotheses if labor markets are correctly characterized by equilibrium models then the price level and real wage are determined independently and separating the real wage into its nominal and price

targeting maps an asset based approach to geographic targeting summary proper targeting of policy interventions requires reasonable estimates of the benefits of the alternative options to inform such decisions we develop an integrated approach stemming from the small area estimation literature that estimates the marginal returns to a range of assets across geographically defined subpopulations we create a series of maps that can be overlaid with traditional poverty maps to identify strong candidate areas for intervention though an efficiency equity tradeoff sometimes exists we apply our method using recent ugandan data results are consistent with independent empirical findings and suggest asset specific transfer schemes would improve with a spatially targeted strategy

the economics of poverty traps and persistent poverty an asset based approach abstract longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty while a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty this paper develops an asset based approach to poverty analysis that makes it possible to distinguish deep rooted persistent structural poverty from poverty that passes naturally with time due to systemic growth processes drawing on the economic theory of poverty traps and bifurcated accumulation strategies this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long term persistent structural poverty as well as relevant extensions of the popular foster greer thorbecke class of poverty measures the paper closes with reflections on how asset based poverty can be used to underwrite the design of persistent poverty reduction strategies

on real and sticky price theories of the business cycle after presenting some facts about the growth of government in western industrialized countries possible causes of this development are analyzed from a public choice perspective next some empirically tested theories which seek to explain this growth are discussed finally possible consequences for efficiency and individual liberty are examined it is shown that both the number and size of interest groups age of democracy as stated by mancur olson 1982 and the increasing share of government expenditure in gdp seem to exert a negative influence on the growth rate of gdp copyright 1986 by ohio state university press

on the absence of positive wage indexation this paper rationalizes the absence of positive wage indexation in labour contracts that is of indexing provisions that link wage increases to inflation we investigate the equilibrium of a policy game in a stochastic economy in which wage setters and a policy maker interact strategically in order to determine the preferred degree of wage indexation and an optimal stabilization rule respectively our conclusion is that nominal wage rigidity and counterinflationary economic policy represent the best courses of action when price stability is valued and negative responses of contractual wages to price shocks are ruled out under these assumptions moreover the stochastic structure of the economy has no bearing on the optimality of maximal real wage flexibility this paper presents an argument for explaining nominal wage rigidity in labour contracts we investigate the equilibrium of a policy game in a stochastic economy in which wage setters and a policy maker interact strategically in order to determine the preferred degree of wage indexation and an optimal intervention rule respectively our conclusion is that indexing provisions that maximize the flexibility of real wages and counter inflationary economic policy represent the best courses of action for the players in the absence of schemes that create a negative correlation between wage and price movements maximal real wage flexibility is attainable through zero indexation or rigid nominal wages the crucial assumption that drives this result is that some price stability is desirable for the policy maker the introduction of price stability as a goal seems eminently justified from a practical standpoint the federal reserve system s legislative mandate from the federal reserve reform act of 1977 the ongoing debate about the house joint resolution 409 and the delors report which speaks of an unequivocal commitment to maintain price stability as the primary objective of the european system of central banks

do changes in the labour market take families out of poverty determinants of exiting poverty in brazilian metropolitan regions using survival models we test whether short term changes in the labour market affect poverty duration data are from the brazilian monthly employment survey such a monthly dataset permits more accurate estimations of events than using annual data but its panel follows households for a short period then methods that control for both right and left censoring should be used the results are as follows households with zero income are not those with the lowest chances of exiting changes in aggregate unemployment do not affect poverty duration and increasing wages in the informal sector has a negative effect on poverty duration

policy effectiveness in an open multi market economy with risk neutral exchange rate speculation abstract in an open multi market equilibrium model of the business cycle the informational role of a forward exchange market is that the forward rate aggregates individual perceptions of the aggregate state of the economy in the case of risk neutral exchange rate speculation the forward rate perfectly reveals average expectations of current nominal shocks that hit the economy this paper analyzes the informational implications of forward speculation when markets are structurally diverse the two types of structural diversity considered are heterogeneous price elasticities of output demand and supply and asymmetric information between traders in output markets and traders in asset markets in contrast to previous results the paper shows that risk neutral speculation is not in general sufficient to generate a fully revealing rational expectations equilibrium in which monetary policy is ineffective

pathways into and out of poverty a study of rural household wealth dynamics in kenya this study identifies the factors associated with smallholder farm households that have risen out of poverty or descended into poverty between 1997 and 2007 in kenya the study uses data from a nationwide balanced panel of 1 275 households and data from detailed retrospective life history survey of 84 households that had experienced either an appreciable improvement or decline in their asset wealth over the 10 year panel period the results indicate that household welfare dynamics are associated with a disparate set of idiosyncratic and unexpected shocks such as death and chronic illness demographic factors proximity to infrastructural facilities as well as intergenerational wealth transfers

sticky prices as coordination failure this paper links the coordination failure and menu cost approaches to the microeconomic foundations of keynesian macroeconomics if a firm s desired price is increasing in others prices then the gain from price adjustment after a nominal shock is greater if others adjust this strategic complementarity leads to multiple equilibria in the degree of rigidity welfare may be much higher in the equilibria with less rigidity thus nominal rigidity arises from a failure to coordinate price changes jel e12 e30 keynesian macroeconomics waned in the 1970 s because economists grew disenchanted with its weak microeconomic foundations the central difficulty was that keynesian models were based on ad hoc rigidities in nominal wages and prices the 1980 s produced two approaches to reviving keynesian theory the menu cost literature n gregory mankiw 1985 george akerlof and janet yellen 1985 seeks to provide rigorous explanations for nominal rigidities these papers argue that small frictions in price setting are enough to produce large nominal rigidities in contrast the coordination failure literature russell cooper and andrew john 1988 abandons nominal rigidities and seeks alternative foundations for keynesian models the central idea is that many economic activities such as production e g john bryant 1983 trade e g peter diamond 1982 and investment e g nobuhiro kiyotaki 1988 exhibit synergism or strategic complementarity one agent s optimal level of activity depends positively on others activity strategic complementarity can lead to multiple equilibria with high activity equilibria superior to low activity equilibria thus an economy may be stuck in an underemployment equilibrium even though a superior equilibrium exists models with nominal rigidities and models with coordination failures are often presented as competing paradigms 1 this paper shows that this view is incorrect we take a step toward unifying the foundations of keynesian economics by showing that the two sets of ideas are highly complementary nominal rigidity arises from a failure to coordinate price changes this failure has the essential features of coordination failures in previous models flexibility in one firm s price increases the incentives for other firms to make their prices flexible this strategic complementarity leads to multiple equilibria in the degree of nominal rigidity equilibria with less rigidity more active price adjustment are often pareto superior to equilibria with more rigidity these results contribute to our understanding both of coordination failure and of nominal rigidity the range of keynesian phenomena explained by coordination failures is greatly expanded previous coordination failure models contain only real variables and thus ascribe no role to monetary policy or other determinants of nominal spending our results suggest that coordination failure is at the root of inefficient nonneutralities of money theories of nominal rigidities gain new empirical and policy im

growth and chronic poverty evidence from rural communities in ethiopia abstract what keeps some people persistently poor even in the context of relative high growth in this article we explore this question using a 15 year longitudinal data set from ethiopia we compare the findings of an empirical growth model with those derived from a model of the determinants of chronic poverty we ask whether the chronically poor are simply not benefiting in the same way from the same factors that allowed others to escape poverty or whether there are latent factors that leave them behind we find that this chronic poverty is associated with several initial characteristics lack of physical assets education and remoteness in terms of distance to towns or poor roads the chronically poor appear to benefit from some of the drivers of growth such as better roads or extension services in much the same way that the non chronically poor benefit however they appear to have lower growth in this period related to time invariant characteristics and this suggests that they face a conside

rural poverty dynamics in kenya structural declines and stochastic escapes we use panel survey data and household event histories to explore patterns of rural poverty dynamics in kenya over the period 2000 2009 we find substantial mobility across poverty categories using economic transition matrices drawing on asset based approaches we distinguish stochastic from structural poverty transitions few households successfully escaped poverty through asset accumulation up to 35 of the upwardly mobile while a large proportion of households up to 66 declining into poverty experienced structural transitions using household event histories we find significant differences across structural poverty transition classes in livelihood strategies household level shocks and other factors

converting asset holdings into livelihood an empirical study on the role of household agency in south africa summary this paper analyzes the complexities of converting assets into livelihood and the role that agency constraints play drawing inspiration from the capabilities approach and using household data from south africa linkages between assets and agency are identified by decomposing asset endowments impact on future livelihood by employing a method of path analysis akin to early heritability of traits studies theoretical asset based studies of chronic poverty are bridged with capabilities literatures the interaction between assets and agency is shown to be as important as asset to asset complementarities the results have wide ranging policy implications

the economics of poverty traps and persistent poverty empirical and policy implications the moral and economic imperatives to intervene in poverty traps motivate the identification of poverty traps and their structural causes so as to inform the design of appropriate policy responses however empirical identification remains challenging because of poverty traps complexity after reviewing mechanisms that can generate poverty traps we focus on one multiple financial market failures emphasising its heretofore underappreciated testable implications including specific behaviours that are rational only in the presence of a poverty trap we therefore recommend tests for these behaviours rather than more econometrically challenged efforts to directly test for poverty traps in estimated asset dynamics

asset smoothing consumption smoothing and the reproduction of inequality under risk and subsistence constraints abstract a growing literature asks whether low wealth agents can accumulate assets over time or whether they are trapped in poverty this paper develops a stochastic dynamic programming model with endogenous asset price risk to explore savings and portfolio decisions in a resource poor environment characterized by risk and subsistence constraints optimal portfolio strategies are found to bifurcate despite divisible assets and fully rational agents wealthier agents acquire a higher yielding portfolio and pursue conventional consumption smoothing poorer agents acquire a less remunerative portfolio and pursue asset smoothing rather than consumption smoothing asset based risk coping thus results in positive correlation between initial wealth and portfolio rate of return

consumption versus asset smoothing testing the implications of poverty trap theory in burkina faso abstract despite solid theoretical foundations for the notion that poor borrowing constrained households will intertemporally manage assets to smooth consumption the consumption smoothing hypothesis has not always withstood empirical scrutiny this paper reassesses the intertemporal asset management problem with a poverty trap model and shows that we would expect to see asset smoothing not consumption smoothing in the neighborhood of critical asset levels at which optimal accumulation behavior bifurcates we then employ threshold estimation techniques to empirically confirm the co existence of consumption and asset smoothing regimes using a household panel data set from west africa households above the estimated threshold almost completely insulate their consumption from weather shocks whereas those below the threshold do not these results not only indirectly provide evidence of the existence of poverty traps but also speak to the level and incidence of the costs of uninsured risk

income and asset poverty among pastoralists in northern kenya abstractin this study we use household panel data collected in marsabit district of northern kenya to analyse the patterns of livelihood sources and poverty among pastoralists in that area we estimate income poverty using imputed household income relative to the adjusted poverty line and asset poverty using a regression based asset index and tropical livestock units tlu per capita our results indicate that keeping livestock is still the pastoralists main source of livelihood although there is a notable trend of increasing livelihood diversification especially among livestock poor households the majority of households over 70 are both income and livestock poor with few having escaped poverty within the five year study period disaggregating income and asset poverty also reveals an increasing trend of both structurally poor and stochastically nonpoor households the findings show that the tlu based asset poverty is a more appropriate measure of asset poverty in a pastoral setting

migration remittances and capital accumulation evidence from rural mexico this paper studies the link between migration remittances and productive assets accumulation for a panel of poor rural households in mexico over the period 19972006 in a context of nancial markets imperfections migration may act as a substitute for imperfect credit and insurance provision through remittances from migrants and thus exert a positive eect on investment however it may well be the case that remittances are channelled towards increasing consumption and leisure goods exploiting within family variation and an instrumental variable strategy we show that migration indeed accelerates productive assets accumulation moreover when we look at the eect of migration on consumption of non productive assets durable goods we nd instead a negative eect our results then suggest that

the poor stay poor household asset poverty traps in rural semi arid india summary although identifying household level poverty dynamics would have important implications for poverty reduction policies empirical evidence is still scant this paper employs a novel semiparametric panel data estimator that combines the advantages of estimation methods in the existing literature and applies it to a uniquely long panel data set to examine poverty dynamics in three villages in rural semi arid india structural immobility is pervasive the currently poor are likely to remain poor suggesting a structural poverty trap while all households face static asset holdings higher castes larger landholders and more educated households are significantly less likely to be poor

using stated preferences and beliefs to identify the impact of risk on poor households abstract whilst the importance of uncertainty in shaping economic behaviour of poor households is widely acknowledged empirically identifying the impact of risk is difficult by using data on risk preferences and perceptions of risk collected through hypothetical questions in combination with more traditional measures of a household s ability to deal with risk this article identifies the impact of risk on production decisions it shows both that data on stated preferences and beliefs can be usefully utilised to explain household behaviour and that risk has a significant impact on the production decisions of poor households

the relevance of unanticipated money growth in explaining output variation this paper tests a reduced form equation in which real gnp for the united states is explained by deviations of multi period m1 growth rates from ex ante expectations of those rates formed from one to eight quarters earlier the theoretical model is suggested by stanley fischer s 1977 article and may be thought of as a new keynesian model the equations are tested in both level and first difference specifications to allow for possible unit roots empirical results strongly support this model in preference to new classical and keynesian alternatives ex ante expectations or m1 growth are formed from multi period forecasts made by chase econometrics inc between 1970 and 1979

poverty traps and nonlinear income dynamics with measurement error and individual heterogeneity theories of poverty traps stand in sharp contrast to the view that anybody can make it through hard work and thrift however empirical detection of poverty traps is complicated by the lack of long panels measurement error and attrition this paper shows how dynamic pseudo panel methods can overcome these difficulties allowing estimation of non linear income dynamics and testing for the presence of poverty traps the paper explicitly allows for individual heterogeneity in income dynamics to account for the possibility that particular groups of individuals may face traps even if the average individual does not these methods are used to examine the evidence for a poverty trap in labor earnings income and expenditure in mexico and are compared to panel data estimates from a short rotating panel the results do find evidence of nonlinearities in household income dynamics and demonstrate large bias in the panel data estimates nevertheless even after allowing for heterogeneity and accounting for measurement error the paper finds no evidence of the existence of a poverty trap for any group in the sample

gender assets and agricultural development lessons from eight projects ownership of assets is important for poverty reduction and women s control of assets is associated with positive development outcomes at the household and individual levels this research was undertaken to provide guidance for agricultural development programs on how to incorporate gender and assets in the design implementation and evaluation of interventions this paper synthesizes the findings of eight mixed method evaluations of the impacts of agricultural development projects on individual and household assets in seven countries in africa and south asia the results show that assets both affect and are affected by projects indicating that it is both feasible and important to consider assets in the design implementation and evaluation of projects all projects were associated with increases in asset levels and other benefits at the household level however only four projects documented significant positive impacts on women s ownership or control of some types of assets relative to a control group and of those only one project provided evidence of a reduction in the gender asset gap the quantitative and qualitative findings suggest ways that greater attention to gender and assets by researchers and development implementers could improve outcomes for women in future projects

asset versus consumption poverty and poverty dynamics in rural ethiopia several studies have shown conceptually that assets form a more robust basis for identifying the poor than do flow variables like expenditures or income asset based poverty classification can be used to distinguish structural from stochastic poverty and can enable projection of poverty dynamics through time nonetheless little work has empirically compared poverty measurement based on assets and expenditures to indicate the practical implications of the choice of poverty measure this article uses panel data between 1994 and 2004 from ethiopia to generate asset and expenditures based poverty classifications asset dynamics are then explored to test for the existence of multiple asset index equilibria that could constitute evidence of poverty traps results provide evidence of multiple equilibria and show that the asset based poverty classifications predict future asset and expenditures poverty status more accurately than expenditures based measures the findings confirm that the asset based measure could be used to more carefully target poverty interventions

the relative adjustment of wages and prices direct tests within a multiple equation system in order to assess the relative rigidity of the aggregate price level and the nominal wage rate most researchers have focused on the implied behaviour of the real wage rate in response to a purely demand disturbance the present work examines the explicit behaviour of the two variables and is therefore able to analyse the variables short run responses within the context of their defined long run behaviour while the paper reports evidence of long run stability in the real wage rate additional evidence is presented which supports both sticky price and sticky wage models the determining factor is the choice of lag

wealth risk and activity choice cattle in western tanzania abstract imperfect credit markets force households to use their savings for investment profitable activities often require lumpy investments limiting entry by poorer households resulting in increasing welfare differences in tanzania cattle are a profitable but lumpy investment and a liquid asset for consumption smoothing richer households own substantial cattle herds while poorer households specialize in low return low risk activities a dynamic programming model and simulations are presented to analyze entry into asset accumulation under income risk the evidence suggests that households with lower endowments are less likely to own cattle and returns to their endowments are lower

tests of the relation between money and output in the real business cycle model abstract the paper contains tests of the relation between money and output implied by a real business cycle model the tests control for a variety that may affect economic growth and the growth rates of monetary aggregates using u s data from 1953 1 1984 4 we find almost no evidence that the empirical relations between real growth and measures of monetary policy violate the restrictions imposed by the model changes in a set of real variables explain a majority of the variation in gnp growth however substantial variation in gnp growth remains unexplained by the real factors that we consider

do poverty traps exist assessing the evidence why did per capita incomes not increase in burundi haiti and nicaragua countries one possible explanation is a poverty trap which can be understood as a set of self reinforcing mechanisms whereby countries start poor and remain poor poverty begets poverty so that current poverty is itself a direct cause of poverty in the future it implies that much poverty is needless in the sense that a different equilibrium is possible and also that one time policy efforts that break the poverty trap may have lasting effects the concept of a poverty trap at the level of national economies is related to and sometimes based on microeconomic foundations that argue for the existence of poverty traps at the household level the authors discuss behavioral poverty traps as a recent area of research for which the evidence is just starting to accumulate and geographic poverty traps as the most likely form of a trap the policy prescriptions that result are then quite different from the calls for a big push in aid or expansion of microfinance to allow people to overcome credit constraints

the new keynesian synthesis the new keynesians made more rapid progress in understanding the microeconomics of unemployment than in understanding the microeconomics of nominal price rigidity but the past five years have seen important breakthroughs in this second area this paper will describe these breakthroughs discuss our current understanding of nominal rigidity and assess the work that remains to be done

exploring poverty traps and social exclusion in south africa using qualitative and quantitative data abstract recent theoretical work hypothesises that a polarised society like south africa will suffer a legacy of ineffective social capital and blocked pathways of upward mobility that leaves large numbers of people trapped in poverty to explore these ideas this paper employs a mix of quantitative and qualitative methods novel econometric analysis of asset dynamics over the 1993 98 period identifies a dynamic asset poverty threshold that signals that large numbers of south africans are indeed trapped without a pathway out of poverty qualitative analysis of this period and the period 1998 2001 more deeply examines patterns of mobility and confirms the continuation of this pattern of limited upward mobility and a low level poverty trap in addition the qualitative data permit a closer look at the specific role played by social relationships while finding ample evidence of active social capital and networks these are more helpful for non poor households for the poor social capital at best helps sta

poverty status and the impact of formal credit on technology use and wellbeing among ethiopian smallholders summary this paper examines the impact of formal credit largely microfinance on the use of improved technology and on consumption and asset growth across households in different degrees of asset poverty using data from rural ethiopia the analysis finds no relationship between participation in microfinance programs and the use of technologies or consumption growth among the poorest households even though the use of certain technologies like fertilizer contributes to their asset accumulation over time for other households microfinance has positive effects on both consumption and asset growth as well as on the use of improved technology the findings imply variation in constraints faced by different classes of poor households and suggest the value of asset based poverty classifications in identifying target groups for poverty interventions

assessing environmental dependence using asset and income measures evidence from nepal understanding rural environmental dependence in a rural population is an important factor in the framing of environmental policy with the dual aim of tackling poverty and conserving nature firstly this study compares the assessment of environmental dependence between poverty groupings based on income and asset measures using a composite asset index we were able to distinguish the asset poor from the asset non poor we then combined income data with the asset index enabling us to disentangle the stochastic and structural nature of poverty the distribution of poor and non poor households based on income measures was significantly different from that based on asset measures the income poor are substantially more dependent on environmental resources than the income non poor about 15 difference while strikingly minimal difference was observed in environmental dependence between the asset poor and non poor less than 2 difference the level of environmental dependence between the poor and non poor households differs with the choice of welfare measure and combining two of these measures to identify wealth groups provides policy makers with better insight on the variations in environmental dependence

a political model of monetary policy with application to the real fed funds rate abstract we construct an empirical model of u s monetary policy assuming that the federal reserve is an ordinary federal bureaucracy we use the real federal funds rate as our policy measure and show the existence of significant executive legislative and bureaucratic influence on the real rate of interest from 1961 to 1996 we find that presidential party is an adequate statistical measure of executive influence and that the voting scores of the senate banking committee leadership best represent legislative influence we argue that political changes cause systematic and predictable changes in monetary policy

do real business cycle models really exhibit business cycle behavior abstract previous research indicates that real business cycle models are capable of reproducing important features of u s business cycle behavior here i employ classical methods of business cycle analysis to determine how well the cyclical properties of simulated data from a representative real business cycle model match up with postwar u s business cycle characteristics while the simulated model reproduces qualitative features consistent with observed business cycle experience quantitative goodness of fit tests show that for many sectors of the economy the cyclical characteristics of the simulated data deviate significantly from u s business cycle experience

in the eye of the storm the welfare impacts of a hurricane summary the impact of a large covariant shock namely hurricane mitch is examined in the context of household asset holdings in rural nicaragua utilizing household panel data from the period it is found that the hurricane did not have an adverse impact on the ownership of productive assets among the affected households on average on the other hand nonproductive asset holdings seem to have been significantly reduced a further examination confirms that the shock affected the poorest households disproportionally especially in terms of nonproductive assets finally this study presents strong suggestive evidence of a geographical poverty trap within the shock affected areas of the country

interest rate innovations and the business cycle abstract recent evidence from vector autoregressions points towards the importance of interest rate innovations in explaining output variations we show that this evidence supports an interpretation of business cycles based on nominal contractual rigidities rather than cotinuous market clearing

distributed lags aggregation and compounding some econometric implications this paper considers the aggregation of discrete distributed lags in the spirit of houthakker and johansen well known distributed lag models in econometrics are shown to arise from aggregation across heterogeneous microeconomic units the technique of analysis is based on the statistical theory of compound distributions the paper goes on to consider how consistently estimated macro distributed lags may be decomposed into two components which represent respectively the microeconomic response and the heterogeneity in that response related problems of identification and estimation and the interpretive value of the approach are also discussed and illustrations provided

one kind of freedom poverty dynamics in post apartheid south africa abstract a 1993 south african living standards survey documented the legacy of apartheid in the form high levels of inequality and human insecurity drawing on a 1998 re survey of households in the 1993 study this paper explores whether this legacy has been superseded or whether apartheid s end has been only one kind of freedom that has left households in a poverty trap from which they cannot escape after proposing a theoretically grounded dynamic poverty typology that distinguishes stochastic from structural poverty transitions the paper goes on to estimate that significant numbers of the south african poor are potentially trapped in a structural poverty trap and lack the means to escape poverty over time

is late really better than never the farmer welfare effects of pineapple adoption in ghana export agriculture offers potentially high returns to smallholder farmers in developing countries but also carries substantial market risk in this paper we examine the intertemporal welfare impact of the timing of a farmer s entry into the export pineapple market in southern ghana we examine whether farmers who never cultivated pineapple are better or worse off than farmers who decided to adopt pineapple earlier or later relative to their peers and experienced a significant adverse market shock several years prior to our endline survey we use a two stage least squares model to estimate the causal effect of duration of pineapple farming on farmer welfare consistent with economic theory we find that earlier adoption of the new crop brings greater welfare gains than does later uptake but we find that the gains to later uptake of pineapple just before the market shock are small in magnitude just 0 1 standard deviations of a comprehensive asset index indicating that the gains to adoption may be precarious and depend on the context in particular on the severity of prospective market shocks

financial education and behavioral finance new insights into the role of information in financial decisions recent empirical evidence based on surveys and experimental activities within the fields of behavioral finance and financial education has offered economists new empirically based insights into how individuals use information in making financial decisions specifically the importance of information in financial decisions may be reduced or eliminated by psychological aspects of the individual such as a state of overconfidence that is individual or shared with a group or by the individual s limited ability to process complex and abundant information this paper aims to complement this emerging body of literature by studying how individuals perceive and process information when making financial decisions we review these contributions and suggest a number of broad guidelines that can provide a framework for future discussion of this topic within financial decision theory

the source of fluctuations in money evidence from trade credit abstract this paper tests the relative importance of technology shocks and financial shocks as sources of fluctuations in money the model extends the theory of king and plosser 1984 by recognizing that both money and trade credit provide transactions services under certain conditions the co movements between money and trade credit can reveal the nature of the underlying shocks the empirical results strongly suggest that shocks to the financial system account for most of the fluctuations in money in the long run and at business cycle frequencies on the other hand technology shocks appear to be more important at seasonal frequencies

nonfarm employment agricultural shocks and poverty dynamics evidence from rural uganda this article examines the role of off farm employment in poverty reduction over a short period of time by using panel data from 894 rural ugandan households in 2003 and 2005 taking advantage of the unique off farm labor supply and income data we analyzed how households respond to negative agricultural shocks especially through off farm labor supply and income to mitigate crop income loss our analysis indicates that the flexibility of labor time allocation varies across off farm jobs and that only low skilled and low wage jobs tend to be used to mitigate negative shocks especially among the asset poor

learning about the prospects for mobility economic and political dynamics following fundamental policy reform abstract the political left turn in latin america which lagged its transition to liberalized market economies by a decade or more challenges conventional economic explanations of voting behavior this paper generalizes the forward looking voter model to a broad range of dynamic possibly non concave income processes under full information the model implies support for redistributive policies materializes rapidly if few prospects of upward mobility are present in contrast modeling voters evolving beliefs about an unknown income dynamic process shows a slow and polarizing shift toward redistributive preferences simulation using fitted income dynamics suggests that this imperfect information perspective accounts for latin america s right to left political shift and offers additional insights about political dynamics in the face of economic polarization

asset based poverty transition and persistence in rural china this article tests empirically for transition and persistence of poverty in rural china based on the theory of asset based poverty traps it proposes an analytical framework mitigating the problem of endogenous switching between accumulation regimes and disentangling the true state dependence of poverty specifically a dynamic asset threshold separating households into downward and upward mobility regimes is identified after taking households unobserved characteristics and observed regime differentiated accumulation strategies into account the static analysis identifies causality running from settling into a downward mobility regime to the probability of poverty measured by consumption furthermore allowing for endogenous initial poverty status the dynamic analysis finds strong true state dependence in poverty households with the same characteristics are nearly twice as likely to be poor as if they had not previously switched to the accumulation regime assets below the dynamic threshold serve as a conduit through which poverty propagates itself factors that help to break this vicious circle are identified

combining income and assets measures to include the transitory nature of poverty in assessments of forest dependence evidence from the democratic republic of congo abstract a considerable amount of research on poverty environment relations in developing countries under the cifor pen initiative focuses on household income generation from forests using total annual income as a measure of poverty however income alone produces a static picture in a snapshot of time while poverty is a dynamic state that can be a transitory phenomenon using income only also fails to consider that households can liquidate asset to overcome income shocks here we show that using asset quintiles measured by value of assets produce a distinctly different pattern than the commonly observed negative relation between income and forest dependence we then present an approach enabling categorization of households as chronic or transient poor transient rich and rich providing a more nuanced picture than that provided by cifor pen studies so far the validity of groupings is tested by comparing household characteristics and exposure to shocks we then show that the chronic poor are most reliant on forest income while the transient poor consume a higher share of harvested forest products the transient rich have higher agricultural productivity and absolute forest income rich households relies more on business based on the results we suggest recommendations for improving future studies on poverty environment relations

how strong is the evidence for the existence of poverty traps a multicountry assessment introducing this special collection on asset dynamics and poverty traps this article assesses evidence on these issues across eight panel data sets in six countries generally not previously considered in this perspective it examines the importance of assets in relation to chronic poverty and uses parametric and non parametric methods to test for dynamic asset based poverty traps the article finds that chronically poor households have lower levels of assets than others though does not find evidence of the non convexities which would imply a multiple dynamic poverty trap from this base the article introduces the remainder of the articles in this collection which set out many promising approaches to further develop and improve methods and approaches for looking at poverty traps in future

ten years of q squared implications for understanding and explaining poverty summary over the past decade there have been a number of initiatives to promote a more systematic integration of quantitative and qualitative or q squared approaches to poverty analysis in the global south and a large body of literature had emerged the objective of the article is to present a selective review of this empirical work with a view to demonstrate the value it has added for understanding and explaining poverty the evidence strongly suggests that q squared approaches have aided our understanding of the characteristics of the poor and the causes of poverty

a dark side of social capital kinship consumption and savings abstract we explore whether traditional sharing norms in kinship networks affect consumption and accumulation decisions of poor black households in kwazulu natal south africa using a proxy for the number of family dependents our results are consistent with the interpretation that households try to evade their sharing obligations by i accumulating durables that are non sharable at the expense of durables that may be shared and ii reducing savings in liquid assets by attenuating accumulation incentives kinship sharing may come at the expense of income growth if so a culturally induced poverty trap can possibly eventuate we demonstrate tentative evidence that more extensive kinship networks are associated with lower incomes

understanding poverty in cash crop agro forestry systems evidence from ghana and ethiopia this paper examines the linkages between cash crop income and other dimensions of poverty to interrogate assumptions regarding the relationship between agricultural income and poverty alleviation the analysis treats poverty as a multi dimensional and socially disaggregated phenomenon the paper employs a mixed methods approach to case studies of ghana and ethiopia to explore two critical issues first how income from cash crops is linked with other dimensions of poverty second how income and land are socially disaggregated the paper then draws on qualitative data to critically reflect on how poverty is understood within studied communities the results show that some but not all indicators of poverty vary across income quartiles and that significant differences exist across social groups the analysis suggests that although cash crops are essential focusing on increasing income from cash crops will not necessarily have a predictable or progressive impact on wellbeing furthermore the analysis highlights how contextual factors such as the provision of communal services the nature of land holdings and the quality of local governance mediate the potential poverty alleviating outcomes of income increases future development of sustainable intensification strategies should focus on the prevalence of trade offs and the fundamental social relations underpinning poverty dynamics

welfare dynamics in pakistan and ethiopia does the estimation method matter identifying household level welfare dynamics and associated dynamic poverty trap thresholds can have important implications for the targeting of poverty reduction policies the small existing empirical microeconomic literature has found evidence both for and against poverty traps using household panel data from rural pakistan and ethiopia this article examines whether these different results are likely driven by differences in estimation methods or whether they reflect actual differences across settings it applies the estimation methods from the existing literature to the same two datasets and also proposes a novel semiparametric panel data estimator that combines the advantages of the previous fully parametric and nonparametric approaches the results suggest that absent any dynamic poverty trap thresholds the effect of using different estimation methods is secondary having a small influence on the estimated long term level of household well being but not the identification of multiple dynamic welfar

regional agricultural endowments and shifts of poverty trap equilibria evidence from ethiopian panel data we examine changes in patterns of equilibria over time and across regions applied to the ethiopia rural household survey we revisit incidence of multiple equilibria using new nonparametric techniques and examine single equilibria that remain stagnant below the poverty line using quantile regressions we identify differences across the income distribution we introduce the empirical analysis of sequences of equilibria we identify a single equilibrium in 1994 1999 but find a second higher equilibrium emerging in 1999 2004 evidencing a shift from unimodal toward a bimodal asset distribution the most deprived region exhibits a low level stagnant equilibrium despite significant rural income growth nationwide

measuring socio economic status in the millennium villages the role of asset index choice how are poverty analyses and poverty traps assessments affected by the choice among conventional methods of asset index construction to address this question this article uses panel data from four sites in the millennium villages project mvp in malawi tanzania mali and ghana to study the relationship between eight asset indices and the sensitivity of findings related to poverty rates poverty transitions and poverty traps to the index used we find that although estimations of poverty rates and transitions are largely consistent across indices evidence of poverty traps can be conditional on which asset index is used the asset indices studied include structural income principal components factor analysis and a reduced set of assets reflecting the portfolio assessed in the demographic health survey dhs data

the impact of shocks on gender differentiated asset dynamics in bangladesh abstractthis study investigates changes in assets owned by the household head his spouse or jointly in response to shocks in rural agricultural households in bangladesh with household survey panel data looking at changes within households over time we find that weather shocks adversely affect the asset holdings of household heads relatively strongly while predicted negative shocks more strongly lead to assets of both spouses being drawn down the results furthermore suggest that jointly owned assets are not easily sold in response to shocks and that women s asset holdings and coping strategies are shaped by their lower involvement in agriculture

household returns to land transfers in south africa a q squared analysis abstract the south african land reform programme has been widely criticised for its slow pace as well as its apparent lack of contribution to poverty reduction however there is little systematic evidence of the impact of land transfers on their beneficiaries due to data scarcity this paper combines econometric evidence based on official household surveys with qualitative data collected specifically to triangulate and complement the econometric analysis the qualitative data analysis confirms the plausibility of the econometric finding that on average beneficiaries do not gain from participation and suggests that the main reason for the disappointing impact of participation is the incompatibility of consultant led land use plans to land grantees skills

assessing the impact of nerica on income and poverty in central and western uganda persistent food shortage and poverty in sub saharan africa ssa are major development issues new rice for africa nerica was developed to boost crop yield and income of rural households in ssa although its high yielding traits have become fairly well known there is no empirical analysis of its impact on income and poverty by taking the case of uganda where a nerica promoting program was initiated as one of the major poverty eradication measures this study attempts to compare actual income with the hypothetical income without nerica we found that introduction of nerica decreases poverty to a significant extent without deteriorating income distribution
