occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

economic mobility and poverty dynamics in developing countries this study provides an introduction to this special issue of the journal of development studies on economic mobility and poverty dynamics in developing countries in addition to providing a conceptual framework it outlines how the contributions fit into the extant literature a series of regularities emerge across these studies the poor consist of those who are always poor poor at all dates and those who move in and out of poverty with the latter group tending to be strikingly large such movements in and out of poverty are apparent when looking at poverty in either absolute or relative terms changes in returns to endowments can be a potent source of increased incomes finally seemingly transitory shocks can have long term consequences the study concludes by drawing out the policy implications of these regularities

welfare impacts of index insurance in the presence of a poverty trap this paper evaluates the welfare impacts of an index based livestock insurance designed to compensate for satellite based predicted livestock mortality in northern kenya where previous work has established the presence of poverty traps we simulate household wealth dynamics based on rich panel and experimental data the bifurcated livestock dynamics associated with the poverty trap gives rise to insurance valuation that is highly nonlinear in herd size estimated willingness to pay among vulnerable groups who most need insurance is on average lower than commercially viable rates targeted premium subsidization nonetheless appears to offer more cost effective poverty reduction than need based direct transfers

design and rating of risk contingent credit for balancing business and financial risks for kenyan farmers abstractweather related agricultural risks and limited access to credit are serious impediments to agricultural productivity and growth in developing countries this paper describes a novel insuran

persistent poverty and informal credit abstract this paper explores the consequences of nonlinear wealth dynamics for the formation of bilateral credit arrangements to help manage idiosyncratic risk using original data on expected wealth dynamics social networks and informal loans among southern ethiopian pastoralist households we find that the threshold at which expected wealth dynamics bifurcate serves as a focal point at which lending is concentrated informal lending responds to recipients losses but only so long as the recipients are not too poor our results suggest that when shocks can have long term effects loans are best understood as providing a safety net rather than a scale neutral insurance mechanism furthermore the persistently poor are excluded from social networks that are necessary to obtain loans given in response to shocks

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

inter vivos transfers and intergenerational exchange the surge of interest in intergenerational transfers in the past decade has sparked a debate over the motivation for them are transfers given out of altruism or part of an exchange while each motive is probably at work to some extent we know little about whether one motive predominates the question is relevant for issues concerning public income redistribution and inequality in the family but despite its importance empirical evidence about motives is scarce because of limited data we investigate a new data set the national survey of families and households which remedies many of the shortcomings of other data sets containing private transfer information we find that empirical patterns for inter vivos transfers i e transfers between living persons are more consistent with exchange than altruism

asset price shocks financial constraints and investment evidence from japan this paper examines investment spending of japanese firms around the asset price bubble in the late 1980s and makes three contributions to our understanding of how stock valuations affect investment first corporate investment responds significantly to nonfundamental components of stock valuations during asset price shocks fundamentals matter less clearly the stock market is not a sideshow second the time series variation in the sensitivity of investment to cash flow is affected more by changes in monetary policy than by shifts in collateral values finally asset price shocks primarily affect firms that rely more on bank financing and not necessarily those that use equity markets for financing only the investment of bank dependent firms responds to nonfundamental valuations in addition the cash flow sensitivity of bank dependent firms with large collateral assets decreases when asset prices become inflated but increases dramatically when asset prices collapse and monetary policy tightens

risk and insurance in a rural credit market an empirical investigation in northern nigeria credit contracts play a direct role in pooling risk between households in northern nigeria repayments owed by borrowers depend on realizations of random shocks by both borrowers and lenders the paper develops two models of state contingent loans the first is a competitive equilibrium in perfectly enforceable contracts the second permits imperfect information and equilibrium default estimates of both models indicate that quantitatively important state contingent payments are embedded in these loan transactions but that a fully efficient risk pooling equilibrium is not achieved the research is based on a year long survey in zaria nigeria conducted by the author

the international transmission of financial shocks the case of japan one of the more dramatic financial events of the late 1980s and early 1990s was the surge in japanese stock prices that was immediately followed by a very sharp decline of more than 50 percent while the unprecedented fluctuations in japanese stock prices were domestic financial shocks the unique institutional characteristics of the japanese economy produce a framework that is particularly suited to the transmission of such shocks to other countries through the behavior of the japanese banking system the large size of japanese bank lending operations in the united states enables us to use u s banking data to investigate the extent to which this domestic japanese financial shock was transmitted to the united states as well as to identify a supply shock to u s bank lending that is independent of u s loan demand we find that binding risk based capital requirements associated with the decline in the japanese stock market resulted in a decline in commercial lending by japanese banks in the united states that was both economically and statistically significant this finding has added importance given the severe real estate loan problems currently faced by japanese banks how japanese bank regulators decide to resolve these problems will have significant implications for credit availability in the united states as well as in other countries with a significant japanese bank presence

can insurance payouts prevent a poverty trap evidence from randomised experiments in northern kenya index based insurance can have welfare enhancing effects through two pathways by inducing policyholders to change their investment and risk management decisions or by mitigating weather related sh

the formation of risk sharing networks this paper examines the formation of risk sharing networks in the rural philippines we find that geographic proximity possibly correlated with kinship is a major determinant of mutual insurance links among villagers age and wealth differences also play an important role in contrast income correlation and differences in occupation are not determinants of network links reported network links have a strong effect on subsequent gifts and loans gifts between network partners are found to respond to shocks and to differences in health status from this we conclude that intra village mutual insurance links are largely determined by social and geographical proximity and are only weakly the result of purposeful diversification of income risk the paper also makes a methodological contribution to the estimation of dyadic models

risk crop choice and savings evidence from tanzania rural households engaged in agricultural activities face considerable risks in their income process these income risks are especially important if they result in consumption fluctuations this is likely if insurance and credit markets are absent one possible strategy for household is to take up low risk activities even if they imply lower returns such response cannot be viewed independently from the other options available to households to reduce consumption fluctuations this paper focuses on the importance of liquid asset formation for risk taking behaviour by households an intertemporal model of consumption under liquidity constraints is developed in which households can choose between income activities with different returns and riskiness it shows that if liquid asset holdings are large providing a buffer for consumption shortfalls then households will be more willing to take up high risk activities evidence based on survey data from shinyanga district tanzania is presented consistent with this prediction this abstract was borrowed from another version of this item

what s different about banks abstract negotiable certificates of deposit cd s trade in the capital market in competition with other securities like commercial paper and bankers acceptances if cd s must pay lenders competitive monetary interest the reserve tax on cd s is borne by bank borrowers viability of the tax means there must be something special about bank loans that makes some borrowers willing to pay higher interest rates than those on other securities of equivalent risk moreover there must be something special about banks that prevents other intermediaries from competing to assure that it never pays to finance loans with cd s

are there gender differences in demand for index based livestock insurance abstractrisk management plays a role in avoiding and escaping chronic poverty throughout the world particularly for women who are disproportionately negatively affected by shocks using three years of household survey data administrative records and qualitative interviews this paper examines the relationship between gender and demand for index based livestock insurance ibli among pastoralists in southern ethiopia ibli appears to be equitably accessed by men and women alike and we find limited evidence of gender differentiated demand for ibli we also find only modest differences associated with age and share of income from livestock

cross border banking credit access and the financial crisis abstract we study the sensitivity of credit supply to bank financial conditions in 16 emerging european countries before and during the financial crisis we use survey data on 10 701 applicant and non applicant firms that enable us to disentangle effects driven by positive and negative shocks to the banking system from demand shocks that may vary across lenders we find strong evidence that firms access to credit was affected by changes in the financial conditions of their banks during the crisis firms were more credit constrained if they were dealing with banks that experienced a decline in equity and tier 1 capital as well as losses on financial assets we also find that access to credit reflects the balance sheet conditions of foreign parent banks the effect of positive and negative shocks to a bank is greater for riskier firms and firms with fewer tangible assets

traps and thresholds in pastoralist mobility this article presents a new approach to identifying poverty traps in east african pastoralist communities a flexible semiparametric estimation procedure is used to identify a bifurcation in the propensity to engage in the asset based mobile herding livelihood in comparison to the sedentary alternative as a function of herd size the identified threshold is consistent with previous evidence on poverty traps based on modeling herd stock dynamics the approach contributes to an emerging literature that seeks to identify poverty traps through testing the implications of the posited behavioral mechanism behind the trap as opposed to directly modeling asset dynamics the approach is further employed to provide complementary evidence on the relationship between ability and assets in sustaining mobile pastoralism

endogenous matching and the empirical determinants of contract form empirical work on contracts typically regresses contract choice on observed principal and agent characteristics if i some of these characteristics are unobserved or partially observed and ii there are incentives whereby particular types of agents end up contracting with particular types of principals estimated coefficients on the observed characteristics may be misleading we address this endogenous matching problem using a data set on agricultural contracts between landlords and tenants in early renaissance tuscany controlling for endogenous matching has an impact on parameters of interest and tenants risk aversion appears to have influenced contract choice

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

confronting the risk of asset loss what role do livestock transfers in northern kenya play abstract in many low income high risk environments households participate in informal risk sharing institutions involving inter household transfers this study focuses on asset transfers and asset risk the influence of past behavior on access to transfers and wealth differentiated transfer behavior panel data on livestock transfers in northern kenya are analyzed three explanations of livestock transfers are investigated ex post insurance ex ante precautionary savings and redistribution findings indicate that livestock transfers are of limited effectiveness in addressing asset risk and avoiding poverty the findings have implications for both research on risk sharing institutions and for the design of development policies in pastoral areas

income smoothing and consumption smoothing one way that risk averse households protect consumption levels is to borrow and use insurance mechanisms another way common in low income economies is to diversify economic activities and make conservative production and employment choices households thus tend toward limiting exposure only to shocks that can be handled with available credit and insurance typically both types of mechanisms are studied independently but much more can be learned by studying them together first we obtain a more complete picture of risks costs and insurance possibilities second it opens the way to considering biases in standard tests of credit and insurance

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

wealth weather risk and the composition and profitability of agricultural investments despite the growing evidence that farmers in low income environments are risk averse there has been little empirical evidence on the importance of risk in shaping the actual allocation of production resources among farmers differentiated by wealth the authors use panel data on investments in rural india to examine how the composition of productive and nonproductive asset holdings varies across farmers with different levels of total wealth and across farmers facing different degrees of weather risk income variability is a prominent feature of the experience of rural agents in low income countries the authors report evidence based on measures of rainfall variability that the agricultural investment portfolio behavior of farmers in such settings reflects risk aversion due evidently to limitations on consumption soothing mechanisms such as crop insurance or credit markets the authors results suggest that uninsured weather risk is a significant cause of lower efficiency and lower average incomes a one standard deviation decrease in weather risk measured by the standard deviation of the timing of the rainy season would raise average profits by up to 35 percent among farmers in the lowest wealth quartile moreover rainfall variability induces a more unequal distribution of average incomes for a given distribution of wealth wealthier farmers are willing to absorb significant risk without giving up profits to reduce production risk smaller farmers have to invest their limited wealth in ways that reduce their exposure to risk at the cost of lower profit rates the authors found that at high levels of rainfall variability differences in rates of profit per unit of agricultural assets were similar across classes of wealth but over the sample range of rainfall variability these rates of profit were always higher for the poorer farmers than for the wealthier ones suggesting that the disadvantages of small farmers in risk diffusion are more than offset by their labor cost advantage

do banking shocks affect borrowing firm performance an analysis of the japanese experience from 1990 to 1993 the typical firm on the tokyo stock exchange lost more than half of its value and banks experienced severe adverse shocks we show that firms whose debt had a higher fraction of bank loans in 1989 performed worse from 1990 to 1993 and also invested less than other firms did this effect holds when we control for variables that affect firm performance we show further that exogenous shocks to banks during the negotiations leading to the basle accord affected bank borrowers significantly copyright 2000 by university of chicago press

modern value chains and the organization of agrarian production empirical studies of agrarian production in developing countries often find that small farms possess a productivity advantage over larger farms eswaran and kotwal 1986 famously derive this inverse farm size productivity relationship from the structure of agrarian production the focal prediction of their model is that in otherwise equivalent economies a more egalitarian land distribution raises both output and producer welfare the traditional spot procurement system implicit in the eswaran and kotwal model however diverges fundamentally from modern contractual procurement practices we therefore develop a new model of agrarian production in order to determine whether the introduction of a modern value chain alters the welfare effects of land redistribution the inverse farm size productivity relationship persists in our model but we find that more egalitarian land distribution leads to nonmonotonic changes in producer welfare we also find that the introduction of a modern sector can harm the laboring classes

foreign direct investment and regulatory remedies for banking crises lessons from japan can regulatory interventions alleviate financial crises if so which ones work we draw inferences from the japanese banking crisis of the 1990s using a hand gathered database of bank loans gathered from original sources our results indicate that whereas risk based capital infusions in japan similar to those following the 2009 supervisory capital assessment program stress tests in the us were successful in stimulating aggregate lending by japanese banks earlier blanket infusions comparable to the 2008 troubled asset relief program tarp in the us were not effective moreover changes in accounting rules in japan that revalued bank assets similar to the relaxation of mark to market requirements for banks in the us did not increase aggregate japanese bank lending but rather reallocated it capital constraints during the crisis also induced many japanese banks to close their overseas branches and switch their charters from international to domestic this endogenous charter switch reversed the process of foreign direct investment fdi for many japanese banks therefore we use the japanese banking crisis as a natural experiment to test fdi theories and find empirical support for the relative access hypothesis but not for the industrial organization approach or for the relative wealth hypothesis

bank capital and lending relationships this paper investigates the mechanisms behind the matching of banks and firms in the loan market and the implications of this matching for lending relationships bank capital and the provision of credit i find that bank dependent firms borrow from well capitalized banks while firms with access to the bond market borrow from banks with less capital this matching of bank dependent firms with stable banks smooths cyclicality in aggregate credit provision and mitigates the effects of bank shocks on the real economy

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

sequential decision making in production models single equation estimates of production models usually are justified by the assumption that production inputs are chosen as part of a one period decision problem yet most production decisions in agriculture are made sequentially in this paper the farmer s optimal input choices are modeled as optimal controls in a stochastic control problem a two period cobb douglas example is used to show that sequential solutions to production problems may yield models which require either single equation or simultaneous equation estimators functional separability stochastic specification and behavior under uncertainty are discussed in the context of dynamic production models

an economic analysis of yard care and synthetic chemical use the case of san francisco yard care is an economically important household production activity that also has potentially significant environmental or health impacts of particular concern are the possible negative impacts of using synthetic pesticides and fertilizers but economic models and empirical analyses of yard care and chemical use are rare we develop a simple model of household production and consumption to analyze yard care and chemical use we then estimate a multinomial logit model of these behavioral choices with household data from san francisco attitudes towards the quality of one s outdoor residential environment and time scarcity are important determinants of the odds of chemical use whereas financial variables play the major role in determining the odds that people have and care for yards these results could help to improve educational or marketing campaigns that aim to reduce potential or actual problems associated with yard chemical use better data for models similar to this one are needed for future research

household use of agricultural chemicals for soil pest management and own labor for yard work in spite of its potential health and environmental risks and contribution to agribusiness the use of agricultural chemicals for yard care has not been well studied in our discrete continuous choice model estimated with data from a national survey a household chooses how much money if any to initially spend on types of agricultural chemicals and applicators and how much time to subsequently spend on other yard work households in big cities or with large gardens are more likely to use organic chemicals the probability that a household chooses a mix of do it yourself and hired applications of synthetic chemicals increases with income age and the presence of preschoolers among households that apply only synthetic chemicals without hired help those with young children with higher incomes in big cities and with male heads spend more on the chemicals the time that such households spend on other yard work increases with expenditures on the chemicals cancellation of a pesticide registration might create an extra private cost for households with young children even though the ban might reduce external costs

how responsive are private transfers to income evidence from a laissez faire economy abstract in recent years there has been burgeoning interest in how private transfers respond to household income or transfer derivatives much of it is fueled by the specter of crowding out the more responsive are private transfers the more likely they could be supplanted by expansions in public transfers weakening or destroying the latter s distributive impact yet there is also an emerging consensus that actual transfer derivatives are trivial at least for the united states suggesting that crowding out might loom larger in the minds of some economists than in the data but perhaps crowding out is a fait accompli in the united states accordingly we focus on the philippines which has a much smaller public sector we also pursue a novel theoretical angle which generates a sharp non linear relationship between private transfer receipts and income in the form of a spline our empirical work applies recently developed estimation techniques that treat the spline s threshold as an unknown parameter and they uncover transfer derivatives much larger than conventional methods reveal notably private transfers patterns are consistent with altruistic preferences effective risk sharing or both in accord with theoretical predictions however strong transfer derivatives prevail only among low income households our findings suggest that attempts to aid the poor could be thwarted by private responses which leak benefits to richer households in the form of lighter burdens of support for less fortunate kin so the problems that operative private transfers create for public redistribution policy first pointed out by becker and barro over 25 years ago do indeed matter empirically

experimental evidence on the drivers of index based livestock insurance demand in southern ethiopia while index based microinsurance has attracted considerable attention uptake rates have been weak in many low income countries we explore the purchase patterns of index based livestock insurance in southern ethiopia focusing on the role of accurate product comprehension and price we find that randomly distributed learning kits improve subjects knowledge of the products however we do not find strong evidence that the improved knowledge per se causes greater insurance uptake we also find that reduced price due to randomly distributed discount coupons has an immediate positive impact on uptake without dampening subsequent period demand due to reference dependence associated with price anchoring effects

risk financial markets and human capital in a developing country this paper explores the link between financial market incompleteness and human capital accumulation we examine how child school attendance responds to seasonal fluctuations in the income of agrarian households using panel data from rural india to pinpoint market imperfections we study responses to aggregate and idiosyncratic as well as to anticipated and unanticipated income shocks our main finding is that seasonal fluctuations in school attendance are a form of self insurance but one which does not result in a substantial loss of human capital on average

group formation in risk sharing arrangements we study informal insurance within communities explicitly recognizing the possibility that subgroups of individuals may destabilize insurance arrangements among the larger group we therefore consider self enforcing risk sharing agreements that are robust not only to single person deviations but also to potential deviations by subgroups however such deviations must be credible in the sense that the subgroup must pass exactly the same test that we apply to the entire group it must itself employ some self enforcing risk sharing agreement we observe that the stability of subgroups is inimical to the stability of the group as a whole two surprising consequences of this analysis are that stable groups have uniformly bounded size a result in sharp contrast to the individual deviation problem and that the degree of risk sharing in a community is generally non monotonic in the level of uncertainty or need for insurance in the community

no longer trapped promoting entrepreneurship through cash transfers to ultra poor women in northern kenya we examine the short to medium run impacts of the rural entrepreneur access program a poverty graduation program that promotes entrepreneurship among ultra poor women in arid and semi arid northern kenya a context prone to poverty traps the program relies on cash transfers rather than asset transfers in addition to business skills training business mentoring and savings participation in each of the program s three rounds was randomly determined through a public lottery in the short to medium run we find that the program has a positive and significant impact on income savings and asset accumulation similar to more traditional poverty graduation programs that rely on asset transfers

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

unnatural selection perverse incentives and the misallocation of credit in japan we examine the misallocation of credit in japan associated with the perverse incentives faced by banks to provide additional credit to the weakest firms firms are more likely to receive additional bank credit if they arein poor financial condition because troubled japanese banks have an incentive to allocate credit to severely impaired borrowers in order to avoid the realization of losses on their own balance sheets this evergreening behavior is more prevalent among banks that have reported capital ratios close to the required minimum and is compounded by the incentives arising from extensive corporate affiliations

on the costs of a bank centered financial system evidence from the changing main bank relations in japan we examine the effects of bank firm relationships on firm performance in japan when access to capital markets is limited close bank firm ties increase the availability of capital to borrowing firms but do not lead to higher profitability or growth the cost of capital of firms with close bank ties is higher than that of their peers this indicates that most of the benefits from these relationships are appropriated by the banks finally the slow growth rates of bank clients suggest that banks discourage firms from investing in risky profitable projects however liberalization of financial markets reduces the banks market power the close relationship between manufacturing firms and financial institutions in japan has recently been at the center of the debate on the appropriate financial system for the reforming economies of eastern europe as opposed to the anglo saxon separation of finance and industry long term ties between main banks and their client firms involving bank loans bank equity holding and some bank appointed personnel which are common in japan and germany have often been described as a growth oriented financial system that could serve the needs of developing and reformed economiies better than anonymous capital markets modeled after the arnerican and british financial systems the claim that close ties between investmentoriented banks and industrial firms could help overcome the difficulties of relative backwardness dates back to gerschenkron 1962 who investigates european development rosovsky 1961 applies gerschenkron s framework to the analysis of japanese growth more recently aoki patrick and sheard 1994 hoshi kashyap and loveman 1994 and teranishi 1993 among others portray the close ties between finance and industry in japan as an important factor in the international competitiveness of modern japanese

does the japanese stock market price bank risk evidence from financial firm failures the ability of the japanese stock market to appropriately price the riskiness of japanese financial firms has been frequently questioned particularly in light of japan s widespread financial distress in recent years and poor disclosure requirements this paper examines the response in equity returns of japanese banks to the failure of four commercial banks and two securities firms between 1995 and 1998 using event study methodology the analysis finds that share prices of surviving banks on the whole responded unfavorably to the failures and that financially weaker survivors were more adversely affected this suggests that despite the distress and alleged opaqueness bank shareholders were able to use available indicators of financial condition both to incorporate new information quickly into stock prices and to differentiate among banks

group lending local information and peer selection this paper analyzes how group lending programs use joint liability to utilize local information that borrowers have about each other s projects through self selection of group members in the group formation stage these schemes are shown to lead to positive assortative matching in group formation faced with the same contract this makes the effective cost of borrowing lower to safer borrowers because they have safer partners conditional on success their expected dues to the lender are lower than that of riskier borrowers the resulting improvement in the pool of borrowers is shown to increase repayment rates and welfare q 1999 elsevier science b v all rights reserved

stochastic wealth dynamics and risk management among a poor population we use herd history data collected among pastoralists in southern ethiopia to study stochastic wealth dynamics among a poor population although covariate rainfall shocks plainly matter household specific factors including own herd size account for most observed variability in wealth dynamics we find no support for the tragedy of the commons hypothesis past studies may have conflated costly self insurance with stocking rate externalities biophysical shocks move households between multiple dynamic wealth equilibria the lowest suggesting a poverty trap according to nonconvex path dynamics these findings have broad implications for development and relief strategies among a poor population vulnerable to climatic shocks a vast economic literature on risk management rests explicitly or implicitly on the classic friedmanite permanent income hypothesis studies of portfolio management consumption smoothing social insurance and the like all depend on the canonical assumption that stochastic income realisations are drawn from a stationary income distribution leading to consumption smoothing off a stable asset base the possibility of asset accumulation connects this literature to the immense literature on the theory and empirics of economic growth

japan s banking crisis an event study perspective we calculate abnormal stock returns for japanese non financial companies around major events associated with the banking crisis 1995 2000 and find that not all companies were equally sensitive to the malaise of the banking sector the most affected were small leveraged low tech companies with low credit ratings and low market to book ratios this is consistent with credit crunch theories companies with limited access to financial markets are sensitive to changes in bank lending and with claims that innovation is rarely financed by bank debt we do not find much evidence on the alleged misallocation of loans to support ailing bank clients

a comparison of alternative models for the demand for medical care we have tested alternative models of the demand for medical care using experimental data the estimated response of demand to insurance plan is sensitive to the model used we therefore use a split sample analysis and find that a model that more closely approximates distributional assumptions and uses a nonparametric retransformation factor performs better in terms of mean squared forecast error simpler models are inferior either because they are not robust to outliers e g anova anocova or because they are inconsistent when strong distributional assumptions are violated e g a two parameter box cox transformation

insuring well being buyer s remorse and peace of mind effects from insurance this paper estimates the causal effects of index insurance coverage on subjective well being among livestock herders in southern ethiopia the randomization of incentives to purchase index based livestock insurance and three rounds of panel data are exploited to separately identify ex ante welfare gains from insurance that reduces risk exposure and ex post buyer s remorse effects that may arise after the resolution of uncertainty insurance coverage currently in force generates subjective well being gains that are significantly higher than the buyer s remorse effect of an insurance that lapsed without paying out given the temporal correlation in insurance purchase propensity failure to control for potential buyer s remorse effects can bias downward estimates of welfare gains from current insurance coverage

institutional herding business groups and economic regimes evidence from japan we study institutional herding in japan japanese firms are primarily owned by financial institutions and other corporations they may belong to a business group the keiretsu and they have experienced several distinct economic regimes in its recent past overall we find herding in japan occurs on a lower level than in the united states but with a large impact on price movements the price impact is even greater for keiretsu affiliated firms we also find the effects and behavior of institutional herding depends on the economic condition and the regulatory environment

bayesian herders updating of rainfall beliefs in response to external forecasts summary temporal climate risk weighs heavily on many of the world s poor model based climate forecasts could benefit such populations provided recipients use forecast information to update climate expectations we test whether pastoralists in southern ethiopia and northern kenya update their expectations in response to forecast information the minority of herders who received these climate forecasts updated their expectations for below normal rainfall but not for above normal rainfall this revealed preoccupation with downside risk highlights the potential value of better climate forecasts in averting drought related losses but realizing any welfare gains requires that recipients strategically react to these updated expectations

how have borrowers fared in banking mega mergers previous studies of event returns surrounding bank mergers show that banks gain value in megamergers and additional value when they absorb in market competitors a portion of these gains has been traced to the increased bargaining power of banks vis a vis regulators and other competitors we demonstrate that increased bargaining power of megabanks adversely affects loan customers of the acquired institution wealth losses are greater when loan customers are credit constrained the loan customer is smaller or the acquisition is an in market deal these findings reinforce complaints that the ongoing consolidation in banking has unfavorably affected the availability of credit for smaller firms and especially capitalconstrained firms
