how do people cope with natural disasters evidence from the great hanshin awaji kobe earthquake in 1995 this paper investigates the coping strategies employed by victims of the great hanshin awaji kobe earthquake in 1995 using a unique household data set we show that households that held a large amount of collateralizable assets before the catastrophe and were free from a binding borrowing constraint were able to maintain their consumption levels by borrowing in contrast households subject to a binding borrowing constraint before the disaster were unable to borrow to cope with the losses inflicted by the earthquake on the other hand both types of households relied on private transfers depending on the extent of the damage

rent seeking and rent dissipation a neutrality result abstract we consider rent seeking contests between at least two agents who might value the prize differently we capture a wide range of institutional aspects of contests by analyzing a class of contest success functions fulfilling several properties the main properties are anonymity and a condition on the elasticity of a rent seeker s win probability with respect to her effort we show the existence of a mixed strategy equilibrium and establish equilibrium payoffs in this equilibrium complete rent dissipation holds our results imply a partial robustness result for the all pay auction

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

energy rent and public policy an analysis of the canadian coal industry abstract this paper analyses issues in resource rent through a case study of the canadian coal industry a model of the coal industry is constructed to estimate the magnitude of rent and distribution of coal rent between government and industry over the 30 year period from 1970 to 2000 disaggregation of results by coal sector shows that rent varied widely with one sector generating substantial rent and other sectors incurring large losses the pattern of development of the coal sector followed what can be termed a rent dissipation cycle in which the generation of rent in the profitable sector created excessively optimistic expectations that encouraged new entrants to dissipate rent by developing uneconomic capacity the analysis also shows that the system used to collect rent was ineffective the public owner collected only one third of the rent on the profitable mines and collected royalty revenue from the unprofitable mines even though no rent was generated the case study illustrates that improvements in private sector planning based on a better appreciation of resource market fundamentals elimination of government subsidies that encourage uneconomic expansion and more effective rent collection are all needed to avoid rent dissipation and increase the benefits of energy development in producing jurisdictions the study also illustrates that estimates of rent in the resource sector should disaggregate results by sector and make adjustments for market imperfections to accurately assess the magnitude of potential rent

rent seeking mechanism for safety supervision in the chinese coal industry based on a tripartite game model abstract there are extensive governmental rent seeking activities in safety supervision of the chinese coal industry the rents come from industry safety barriers low resource taxes and privilege policies for coalmining enterprises the rent seeking mechanism was analyzed using a model comprising dynamic games with incomplete information the equilibrium results indicate that the probability of national supervision is influenced by penalties and bribery there is negative correlation with penalties and positive correlation with bribery the rent seeking probability of a governmental safety supervision department is influenced by several factors and positively correlates with the cost of national supervision the probability of bribery of coalmining enterprises is influenced by several factors and positively correlates with wages of governmental departments and a reasonable rent seeking range reversed rent seeking reduces the probability of bribery but it s not worth recommending some recommendations are proposed

rent seeking bureaucracies and oversight in a simple growth model abstract following recent cross country empirical work research on public policy and growth has come to examine the impact of inefficient or corrupt bureaucracies most of this work has emphasized the interactions of bureaucracies with private markets by contrast this paper focuses on the relationship between rent seeking bureaucracies and their political authority we show that when oversight is relatively costly as in many developing economies the political authority exercises little monitoring of its agencies which reduces the effectiveness of productive government spending moreover when the technology used to provide public services is poor bureaus better succeed in requesting overly large budgets before triggering any monitoring both of these characteristics contribute to reducing the growth rate of already poor economies

do financial constraints hold back innovation and growth evidence on the role of public policy abstract this paper provides evidence that capital market imperfections hold back innovation and growth and that public policy can complement capital markets we deliver the evidence by studying the effects of government funding on the behavior of smes in finland by adapting the methodology recently proposed by rajan and zingales rajan r g zingales l 1998 financial dependence and growth american economic review 88 pp 559 587 to firm level data we show that government funding disproportionately helps firms from industries that are dependent on external finance we demonstrate that the result is economically significant and robust to a variety of tests

nonmarket institutions for credit and risk sharing in low income countries the design credit and risk institutions in low income countries provides one of the most exciting testing grounds for theories of contracting with imperfect information and limited enforcement this paper reviews some of the recent literature with a special focus on nonmarket institutions that cope with risk and provide credit this literature attempts to bring together insights from economic theory especially information economics contract theory and mechanism design theory however it is also applied being motivated by the circumstance of the poor countries that their authors have visited and studied

relative wage movements and the distribution of consumption we analyze how relative wage movements among birth cohorts and education groups affected the distribution of household consumption and economic welfare our empirical work draws on the best available cross sectional data sets to construct synthetic panel data on u s consumption labor supply and wages during the 1980s we find that low frequency movements in the cohort education structure of pretax hourly wages among men drove large changes in the distribution of household consumption the results constitute a spectacular failure of between group consumption insurance a failure not explained by existing theories of informationally constrained optimal consumption behavior a welfare analysis indicates that the cost of between group consumption variability is larger than the cost of aggregate consumption variability by two orders of magnitude

rent seeking and innovation innovations and their adoption are the keys to growth and development innovations are less socially useful but more profitable for the innovator when they are adopted slowly and the innovator remains a monopolist for this reason rent seeking both public and private plays an important role in determining the social usefulness of innovations this paper examines the political economy of intellectual property analyzing the trade off between private and public rent seeking while it is true in principle that public rent seeking may be a substitute for private rent seeking it is not true that this results always either in less private rent seeking or in a welfare improvement when the public sector itself is selfish and behaves rationally we may experience the worst of public and private rent seeking together

time patience and specialization patterns in the presence of asset trade specialization patterns in an open economy two sector growth model with endogenous capital accumulation are examined in the presence of free international lending and borrowing without free international lending and borrowing it is known that whereas the less time patient country decumulates real capital the more patient country accumulates real capital and eventually specializes in a capital intensive industry however free trade of international financial assets causes a dramatic change in long run specialization patterns in this case the less patient country may well specialize in the capital intensive industry and the more patient country in the labor intensive industry

is consumption growth consistent with intertemporal optimization evidence from the consumer expenditure survey in this paper we show that some of the predictions of models of consumer intertemporal optimization are in line with the patterns of nondurable expenditure observed in u s household level data we propose a flexible specification of preferences that allows multiple commodities and yields empirically tractable equations we estimate preference parameters using the only u s micro data set with complete consumption information we show that previous rejections can be explained by the simplifying assumptions made in previous studies we also show that results obtained using good consumption or aggregate data can be misleading

risk sharing between and within families this paper uses the panel study of income dynamics to test whether risk sharing is complete between or within american families the tests accommodate a wide variety in the configuration and availability of family data the test results reject inter as well as intra family full risk sharing even assuming that leisure is endogenous or that leisure and consumption are nonseparable

wealth varying intertemporal elasticities of substitution evidence from panel and aggregate data abstract this paper constructs and estimates a model of consumer preferences in which the intertemporal elasticity of substitution ies of consumption expenditure rises with the level of wealth the purpose of this paper is to measure the effect that systematic variation in the ies of poor and rich consumers has on the ies of aggregate consumption expenditure we find economically significant differences in the ies of poor and rich consumers in indian panel data on the consumption of individual households we also find economically significant differences in the ies measured in aggregate time series data for the u s and india

when less is more rationing and rent dissipation in stochastic contests this paper shows how to maximize revenue when a contest is noisy we consider a case where two or more contestants bid for a prize in a stochastic contest where all bidders value the prize equally we show that whenever a tullock contest yields under dissipation the auctioneer s revenue can be increased by optimally fixing the number of tickets in particular in a stochastic contest with proportional probabilities it is possible to obtain almost full rent dissipation we test this hypothesis with a laboratory experiment the results indicate that as predicted revenue is significantly higher in a lottery with rationing than in a standard lottery on the other hand an alternative rationing mechanism that does not limit total expenditures fails to increase revenue relative to a standard lottery

testing for full insurance using exogenous information we strongly reject the full insurance hypothesis using testing variables that are not decision variables for the households under investigation we find that households are not insured against changes in the unemployment rate associated with the household head s occupational category using this exogenous information we also investigate the appropriateness of exogeneity assumptions on idiosyncratic variables that have been used as testing variables in the full insurance literature it is shown that several exogeneity assumptions made in the existing literature are potentially problematic

decreasing relative risk aversion risk sharing and the permanent income hypothesis this article develops a method for testing the risk sharing hypothesis rsh against various versions of the permanent income hypothesis pih while allowing for heterogeneity in risk preferences across households using 1 year and longer differences in household total nondurable consumption data from indian villages we find evidence that favors the rsh over the pih at the village level

risk and insurance in village india comment the protection of poor households in high risk agrarian economies from shocks to their incomes has often been seen as a compelling motive for various forms of policy intervention including transfers of cash or food credit subsidies and public employment schemes for a survey see lipton and ravallion 1995 the desirability of such safety net policies clearly depends on how well pre existing risk sharing arrangements work while it is commonly thought that without effective policy intervention rural households are vulnerable to village wide shocks such as adverse prices or poor rains it is less clear to what extent risk sharing institutions within the village mitigate the effects of idiosyncratic income risk stemming for instance from ill health or localized crop damage 2 several recent papers have used household level data to implement tests of risk sharing that might inform such concerns 3 these tests are based on the proposition that with perfect risk sharing consumption at the household level should be insured against idiosyncratic risks and thus depend solely on the realization of the aggregate risk wilson 1968 diamond 1967 townsend 1994 tests this implication of perfect intra village risk sharing using longitudinal household data on consumptions and incomes for three villages in india he reports that the full insurance hypothesis provides a surprisingly good benchmark in that household consumptions co move and do not appear to be much influenced by contemporaneous own income our aim here is to examine the robustness of this potentially important finding we have two main concerns the first is that the specification townsend adopts potentially biases his test towards the null hypothesis of full insurance because it yields inconsistent estimates of the key test parameter under a plausible alternative we therefore estimate a different specification that generates consistent estimates under both the null and the alternative our second concern is that a particular form of measurement error in the consumption data townsend uses may have further biased his results toward the null hypothesis of full insurance to address this concern we use an instrumental variables procedure when we implement the test of consumption insurance with townsend s consumption data we also re estimate the test equations with a measure of consumption derived from the same underlying primary data by an alternate method finally townsend reports 1discussions with robert townsend stimulated our interest in this investigation the staff of the

the sensitivity of consumption to transitory income estimates from panel data on households we investigate the stochastic relation between income and consumption specifically consumption of food within a panel of about 2 000 households our major findings are 1 consumption responds much more strongly to permanent than to transitory movements of income 2 the response to transitory income is nonetheless clearly positive 3 a simple test independent of our model of consumption rejects a central implication of the pure life cycle permanent income hypothesis the observed covariation of income and consumption is compatible with pure life cycle permanent income behavior on the part of80 percent of families and simple proportionality of consumption and income among the remaining 20 percent as a general matter our findings support the view that families respond differently to different sources of income variations in particular temporary income tax policies have smaller effects on consumption than do other more permanent changes in income of the same magnitude this abstract was borrowed from another version of this item

rent seeking in groups abstract rent seeking contests between groups involve conflicts of interests at the levels of individuals groups and the society as a whole we conduct a series of economic experiments to study the behavior of groups and individuals competing against each other in rent seeking contests we find substantial over contribution to rent seeking relative to the equilibrium predictions of standard models regardless whether individuals compete against other individuals groups compete against other groups or individuals compete against groups

a simple test of consumption insurance are consumers effectively insured against idiosyncratic shocks to income or wealth either by formal institutions such as charities private insurance and government programs or by informal mechanisms such as gifts and loans from relatives friends and neighbors under full insurance consumption growth should be cross sectionally independent of idiosyncratic variables that are exogenous to consumers this proposition is tested by cross sectional regressions of consumption growth on a variety of exogenous variables full insurance is rejected for long illness and involuntary job loss but not for spells of unemployment loss of work due to strike and an involuntary move

asset pricing with multiplicative habit and power expo preferences abstract multiplicative habit introduces an additional consumption risk as a determinant of the equity premium and allows time preference and habit strength in addition to risk aversion to affect the price of risk a model combining multiplicative habit and power expo preferences cannot be rejected

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

informality and rent seeking bureaucracies in a model of long run growth abstract this paper explores the links among growth the informal economy and rent seeking bureaucracies the presence of congestion associated with the enforcement of property rights implies that informality can be useful whether bureaucratic rent seeking is detrimental to growth then depends on how good a substitute informality is to production in the formal sector in order to create profits which can be appropriated rent seeking bureaucrats limit entry into the formal economy as a result firms operate in the informal sector even when the cost of informality is high in which case lower growth emerges however when the cost of informality is low a large number of firms choose to operate informally irrespective of entry conditions in the latter case growth is unaffected by a rent seeking bureaucracy as entry restrictions in the formal economy do not bind

decreasing relative risk aversion and tests of risk sharing the relative risk aversion rra coefficient of a household whose consumption is close to the subsistence level may be very high for example if consumption is exactly at the subsistence level the household may not be willing to bear any risk if this is the case then the rra coefficient must be a decreasing function of wealth for poor households therefore we should allow the possibility of decreasing rra drra in testing the full risk sharing hypothesis however existing tests in the empirical literature are derived using preferences that exhibit either increasing or constant rra even when they are applied to data containing low income households we therefore use a hyperbolic absolute risk aversion hara utility which implies increasing constant and decreasing rra as special cases to test full risk sharing hypothesis using the international food policy research institute ifpri and the international crops research institute of the semi arid tropics icrisat household level data sets we find evidence in support of the drra hypothesis along with evidence favoring full risk sharing hypothesis at the village level and evidence against the hypothesis at the inter village level when rra is restricted to be constant we replicate the previous results in the literature reject the full risk sharing hypothesis at both levels our tests however reject this restriction and favor drra in almost all cases these results suggest that it is important to allow for drra in testing the full risk sharing hypothesis when data containing low income households are investigated this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this this abstract was borrowed from another version of this item

risk sharing and information in village economies arrangements for achieving efficient risk sharing vary depending on the information available to agents in the economy the usual euler equation restricts efficient allocations in an economy which obeys the permanent income hypothesis while efficient allocations in an economy with private information and long term contracts satisfy a symmetric restriction but not the euler equation full insurance arrangements are unique in that they satisfy both restrictions we look at an environment in which it seems likely that long term contracts play a role in mitigating the effects of private information three village economies in south india the evidence that consumption allocations satisfy the private information restriction is quite strong for households in two of the three villages the evidence for the third village suggests that while consumption for some households satisfies the private information restrictions other households consumption obey the permanent income hypothesis

consumption smoothing migration and marriage evidence from rural india a significant proportion of migration in low income countries particularly in rural areas is composed of moves by women for the purpose of marriage we seek to explain these mobility patterns by examining marital arrangements among indian households in particular we hypothesize that the marriage of daughters to locationally distant dispersed yet kinship related households is a manifestation of implicit interhousehold contractual arrangements aimed at mitigating income risks and facilitating consumption smoothing in an environment characterized by information costs and spatially covariant risks analysis of longitudinal south indian village data lends support to the hypothesis marriage cum migration contributes significantly to a reduction in the variability of household food consumption farm households afflicted with more variable profits tend to engage in longer distance marriage cum migration the hypothesized and observed marriage cum migration patterns are in dissonance with standard models of marriage or migration that are concerned primarily with search costs and static income gains

consumption over the life cycle and over the business cycle the main aim of this paper is to assess the validity of the life cycle model of consumption in particular we address an issue that has recently received much attention especially in the macroeconomic literature that of excess sensitivity of consumption growth to income growth we do this using a time series of cross sections and a novel and flexible parameterization of preferences the former allows us to address aggregation issues directly while with the latter we can allow both the discount factor and the elasticity of intertemporal substitution eis to be affected by various observable variables and lifetime wealth the main findings can be summarized as follows i the excess sensitivity of consumption growth to labor income disappears when we control for demographic variables this is true both at life cycle and business cycle frequencies ii estimation of a flexible specification of preferences indicates that the elasticity of intertemporal substitution is a function of several variables including the level of consumption the eis increases with the level of consumption as expected iii the variables that change the eis are also important in explaining why we observe excess sensitivity over the business cycle iv we are able to reconcile our results with those reported both in the macro and micro literature v in our specification the elasticity of intertemporal substitution is not very well determined this result however should be taken with care as we have not made an effort to construct a preferred specification which would probably include additional controls for labor supply behavior the evidence presented shows that the life cycle model cannot be easily dismissed indeed we believe that the model does a good job at representing consumption behavior both over the life cycle and over the business cycle
