can education subsidy reverse falling fertility the case of taiwan abstract the education subsidy in taiwan is available for government employees only in 1996 the government ceased to index the education subsidy for inflation which created a natural experiment ideal for studying the effect of the education subsidy on fertility using the difference in differences approach we find that the reform reduced the fertility probability for public sector households by 17 per cent and this negative response appears to be permanent the estimated probability elasticity of fertility is 0 05 which is smaller than that of personal tax exemption 0 8 the results also suggest that the education subsidy has a heterogeneous effect on fertility across income groups

the effect of sporting success and management failure on attendance demand in the bundesliga a revealed and stated preference travel cost approach abstractthis study examines the private consumption benefits of sports attendance using revealed and stated preference data from 28 football bundesliga teams across three divisions survey respondents were presented with positive sporting success and negative management failure scenarios and asked for the number of game trips if each scenario occurred the results of a pooled random effects poisson model show that travel costs and ticket price have a significant negative effect on the number of home game trips the weighted consumer surplus per game trip including travel costs and ticket prices is 345 consumer surplus per game trip was found to change by 41 first division and 98 second and third division if the positive scenario occurred and by 39 if the negative scenario occurred

women s work and economic development using a cross country dataset and microdata from india and thailand we examine how women s work status changes with economic development several clear patterns emerge women s labor force participation first declines and then rises with development women move from work in family enterprises to work as paid employees fertility declines and gender gaps in education narrow women s education levels and those of their spouses appear to be important determinants of women s labor market activities broad welfare indicators such as mortality rates and education levels indicate that women s well being improves on average with development both in absolute terms and relative to men

use value of cultural experiences a comparison of contingent valuation and travel cost abstract few applications to assess the value of cultural experiences exist this is particularly frustrating for cultural institutions as it provides them with few opportunities to reveal their importance in terms of attractiveness and thus what drives tourism demand this study applies the travel cost method tcm and contingent valuation method cvm to assess the value of two rural cultural institutions in order to compare the results of the valuation methods the results reveal that visitor experiences consist of a core cultural experience as well as other valuable experiences before and after whereas cvm allows for a valuation of the core cultural experience separately from other experiences the tcm is limited to an overall assessment the tcm is therefore an inappropriate measure of the value of the cultural experiences when the total experience includes several other experiences if visitors travel for the sake of only one cultural experience tcm may be preferable due to its simple applicability and cost efficiency if however as is most often the case a cultural experience is part of a bundle of experiences the application of cvm is recommendable this is also the case if only visitors who state the cultural experience to be the primary reason for travelling are included

revealing preferences for leisure time from stated preference data when consumer choice is constrained by time as well as money willingness to pay can be defined with respect to either numeraire the two measures can be related formally within a utility consistent model of choice subject to two constraints furthermore when information is collected on both the respondent s marginal value of time can be identified a system of willingness to pay time and money and the marginal value of leisure time is estimated jointly in an application to california whalewatching and whale stock enhancement the empirical approach can be applied with only minor additions to survey techniques for nonmarket valuation

does globalization increase child labor abstract there is no empirical evidence that trade exposure per se increases child labor as trade theory and household economics lead us to expect the crosscountry evidence seems to indicate that trade reduces or at worst has no significant effect on child labor consistently with the theory a comparatively well educated labor force and active social policies appear to be conducive to a reduction in child labor for countries with a largely uneducated workforce the problem is not so much globalization as not being allowed to take part in it

testing for forward looking behaviour evidence from the enactment of smoking restrictions abstractthis paper develops a new test for forward looking behaviour based on the establishment of public smoking restrictions given that the announcement of these restrictions effectively increases the future cost of smoking we should expect forward looking smokers to curb their consumption before the restriction is effective due to complementarity between present and future consumption i perform the estimation using detailed high frequency household level purchase data the results provide evidence against the forward looking behaviour of smokers households do not reduce their cigarette purchases before announced public smoking restrictions are established they only do so once the restriction is in effect

estimating the cost of leisure time for recreation demand models abstract in this paper we propose a method of determining the opportunity cost of leisure time with an empirical recreation demand application typically the opportunity cost of leisure time is assumed to be some fraction of the wage rate this practice has limitations first it assumes that individuals can trade time for money at their wage second it offers no guidance about how to value the time of an individual who is not in the labor force this paper proposes a method of determining this cost that does not suffer from these drawbacks an empirical example is provided which demonstrates the proposed approach and contrasts it with commonly applied approaches

the individual travel cost method with consumer specific values of travel time savings the treatment of the opportunity cost of travel time in travel cost models has been an area of research interest for many decades our analysis develops a methodology to combine the travel distance and travel time data with respondent specific estimates of the value of travel time savings vtts the individual vtts are elicited with the use of discrete choice stated preference methods the travel time valuation procedure is integrated into the travel cost valuation exercise to create a two equation structural model of site valuation since the travel time equation of the structural model incorporates individual preference heterogeneity the full structure model provides a travel cost site demand model based upon individualized values of time the methodology is illustrated in a study of recreational birdwatching more specifically visits to a stork village in poland we show that the usual practice of basing respondents vtts on 1 3 of their wage rate is largely unfounded and propose alternatives including a separate component of the travel cost survey aimed at valuation of respondents vtts or as a second best asking if they wish if their journey was shorter and for those who do use full hourly wage as an indicator of their vtts

adapting household behavior to agricultural technology in west bengal india wage labor fertility and child schooling determinants the emergence of the high yielding varieties hyvs as alternatives to traditional varieties tvs of wheat rice and several other crops has been a major event in many developing countries during the last 2 decades the output income and employment augmenting effects of this modern technology have been documented in many regions of the world the existing studies have focused on aggregate economic indicators at national regional and sectoral levels analyses of technological change and household well being are now needed to explore the implications of this process for intrahousehold allocation of the resources among persons and activities the critical household activity is labor force participation in the market in own enterprise or in home production by male female and child members of the household these activities change as household demand for children changes and parents become able and willing to invest more in the health nutrition schooling and training of their children and thereby improve their productivity quality analysis of these interrelated household decisions helps to clarify efficient policies for rural development and to trace the societal repercussions of these policies ii background and objective although much has been written on the green revolution technology at the national and regional levels in india few studies have dealt with the eastern region of the country the question assumes special significance for the eastern indian states because of several factors first this region produces about three fourths of the country s output of rice the major food crop but the yield per acre is less than in other regions the new technology in rice came to this region at a later date

microfinance and poverty in bolivia both in its institutional range and in its penetration of financial markets the microfinance sector in bolivia rivals any in the world and has played a major part in extracting the macro economy from meltdown since the mid 1980s we seek specifically to assess its impact on poverty and do this through small sample surveys on four microfinance institutions two urban and two rural using a range of poverty concepts income generated both through the borrower s enterprise and through the labour market asset holdings and diversity and various measures of vulnerability all the institutions studied had on balance positive impacts on income and asset levels with income impacts correlating negatively with income on account of poor households choosing to invest in low risk low return assets microfinance may however augment vulnerability average debt service ratios of microfinance clients are disturbingly high and if the coping mechanisms used by borrowers fail borrowers may be forced out of the

is addiction rational theory and evidence this paper makes two contributions to the modeling of addiction first we provide new and convincing evidence that smokers are forward looking in their smoking decisions using state excise tax increases that have been legislatively enacted but are not yet effective and monthly data on consumption second we recognize the strong evidence that preferences with respect to smoking are time inconsistent with individuals both not recognizing the true dife culty of quitting and searching for self control devices to help them quit we develop a new model of addictive behavior that takes as its starting point the standard rational addiction model but incorporates time inconsistent preferences this model also exhibits forward looking behavior but it has strikingly different normative implications in this case optimal government policy should depend not only on the externalities that smokers impose on others but also on the internalities imposed by smokers on themselves we estimate that the optimal tax per pack of cigarettes should be at least one dollar higher under our formulation than in the rational addiction case

rational addiction with learning and regret we present a theory of rational behavior in which individuals maximize a set of stable preferences over goods with unknown addictive power the theory is based on three fundamental postulates that consumption of the addictive good is not equally harmful to all that individuals possess subjective beliefs concerning this harm and that beliefs are optimally undated with information gained through consumption although individual actions are optimal and dynamically consistent addicts regret their past consumption decisions and regret their initial assessment of the potential harm of the good addict prone individuals who believe it could not happen to them are most likely to be drawn into a harmful addiction

decomposing world health inequality this study explores global inequality in health status and decomposes it into within and between country inequality we rely on standardized height as our health indicator since it avoids the measurement pitfalls of more traditional measures of health such as morbidity mortality and life expectancy it also avoids measurement problems associated with using monetary variables such as income or expenditure across time or place to compare welfare our calculation of world height inequality indicates that in contrast with similar research on income inequality within country variation is the source of most inequality rather than the differences between countries

energy projects in iceland advancing the case for the use of economic valuation techniques to evaluate environmental impacts decision making in iceland has occurred without reference to economic valuations of the environmental impacts of energy projects environmental impact assessments a legal requirement for nearly all energy projects in iceland since 1994 have played an important role in identifying the environmental impacts of energy projects and proposing mitigation measures however a purely qualitative description of environmental impacts is insufficient to ensure that they are accounted for equivalently with all of the other costs and benefits of a proposed project instead as monetary information concerning the welfare gains or losses of proposed projects is not currently required to be provided to the licensing body orkustofnun there is the potential for sub optimal decision making to occur as this paper sets out a broad variety of non market valuation techniques already exist and could be applied to estimate the value of environmental benefits sacrificed to accommodate such developments these methods and their outcomes could be incorporated within mandatory cost benefit assessments for proposed icelandic energy projects communicating an estimate of the full welfare implications of approvals to decision makers and the public alike and fulfilling an oecd demand for the country to commence such processes

analysis of optimal timing of tourism demand recovery policies from natural disaster using the contingent behavior method this paper examines the applicability of contingent behavior hereafter cb method for analyzing dynamic processes and efficient policies in tourism demand recovery the cb questionnaires used for this study used a hypothetical disaster situation of bird flu in kyoto japan safety event visitor information and price discounting policies were designed accordingly respondents were then asked about their willingness to travel time the results showed the optimal timing for devising pertinent policies during the year we found that the first step requires a safety information announcement within one week immediately after disaster site decontamination the second step is the implementation of event information policy within 24th to 36th week after the disaster the third step constitutes announcing visitor information within the 37th to 52nd week after the second step the final step is the implementation of price discounting policy until the 52nd week immediately after the third step

educational subsidy agricultural development and fertility change in this paper the effects of continuing agricultural technical change on the allocation of resources by households between increments to family size and to schooling are examined within the context of a model of household decision making in which education facilitates innovation an empirical application of the model to data from india indicates consistent with the theory that in farm households more intensively exposed to the new technologies associated with the green revolution fertility was significantly reduced while the level of schooling investment was significantly increased in contrast and also consistent with the model proximity of schools in the absence of technical change had only marginal effects on schooling and little impact on family size

calculating the value of time spent collecting water some estimates for ukunda kenya abstract this article presents two procedures for estimating the value of time spent hauling water in developing countries both approaches are used to derive estimates of the value of time for households in ukunda kenya the results indicate that households in this village place a surprisingly high value on the time they spend collecting water a value approximately equivalent to the wage rate for unskilled labor these findings suggest that the economic benefits of improved water services in developing countries may be much greater than is commonly realized

water works the economic impact of water infrastructure abstract billions of hours are spent each year on water collection in developing countries this paper explores whether improvements in water technologies which decrease household distance to drinking water source and the time intensity of home production enable changes in household time allocation and thereby productivity gains in kyrgyzstan adults reallocate time to leisure and labor on the household farm average yearly household cereals production increased significantly results imply a rate of return to labor equaling 0 11 hour approximately half the hourly farm wage absent evidence of improved adult health results suggest that productivity gains were realized primarily through increased farm labor

public inputs and child schooling in brazil household data from a one percent sample of the 1970 brazilian census are used to analyze the effect of public inputs i e the supply of schooling on children s school attainment in brazil the household data are combined with measures of school availability and quality derived directly from the same census data the measures are based on the number and education of schoolteachers in each of 169 different areas of the country elasticities of demand with respect to these public inputs are estimated these elasticities are high in both rural and urban areas in urban areas the positive effect of public inputs is greater for children from households with poorer and less educated parents in rural areas the positive effect of public inputs is greater if anything for children from households that are relatively better off at least compared to other rural households

valuing cultural world heritage sites an application of the travel cost method to mont saint michel abstractthis article using the zonal version of the travel cost method ztcm provides the first economic valuation of recreational trips to mont saint michel msm the msm was designated as united nations educational scientific and cultural organization world heritage site in 1979 and is the most visited coastal site in france the potential effects on consumer surplus cs estimates of some aspects of the ztcm are considered namely the treatment of the multiple purpose destination mp d trips the inclusion of the opportunity cost of time oct in the recreation demand model and the heterogeneity in the preferences the heterogeneity in the preferences is examined through a random parameters poisson model rppm the rppm generalizes the standard poisson model spm by allowing coefficients of explanatory variables to vary randomly across geographical units rather than being fixed our results show that 1 substantial cs values are associated with the msm 2 excluding ignoring mp d trips resul

taxes cigarette consumption and smoking intensity reply this paper shows that smoking intensity i e the amount of nicotine extracted per cigarette smoked responds to changes in excise taxes and tobacco prices we exploit nhanes data covering the period 1988 to 2006 across many us states moreover using panel data from the coronary artery risk development in young adults cardia study we provide new evidence on the importance of cotinine measures in explaining long run smoking behavior we show the importance of smoking intensity as a long run determinant of smoking cessation we also investigate the sensitivity of smoking cessation to changes in excise taxes and their interaction with smoking intensity

the recreational value of lake mckenzie fraser island an application of the travel cost method lake mckenzie is one of the most highly used and popular visitor destinations of all fraser island s natural sites attracting 2000 visitors a day in peak periods many consider this level of visitation to be unsustainable and the management authority is currently considering a range of management options to address this issue in assessing the alternatives it is useful to have some idea of the recreational use value of the lake under the current regime as it is this value that is at risk if visitor numbers are to be reduced this paper using the zonal travel cost method estimates the recreational use value of fraser island and lake mckenzie for australian resident independent visitors

achieving child health related millennium development goals the role of infrastructure a comment summary using the differences observed across countries and asset quintiles within countries fay leipziger wodon and yepes argue that basic infrastructure brings large reductions in child mortality and stunting their estimation method makes a number of questionable assumptions some of which can be readily relaxed with the same data on using an alternative estimator and augmenting their data set to include female schooling one finds little sign that better infrastructure lowers either child mortality or stunting the infrastructure impacts found by fay et al stem from a combination of functional form misspecification latent country effects and omitted quintile specific schooling effects

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

estimating price elasticities when there is smuggling the sensitivity of smoking to price in canada a central parameter for evaluating tax policies is the price elasticity of demand for cigarettes but in many countries this parameter is difficult to estimate reliably due to widespread smuggling which significantly biases estimates using legal sales data an excellent example is canada where widespread smuggling in the early 1990s in response to large tax increases biases upwards the response of legal cigarette sales to price we surmount this problem through two approaches excluding the provinces and years where smuggling was greatest and using household level expenditure data on smoking these two approaches yield a tightly estimated elasticity in the range of 0 45 to 0 47 we also show that the sensitivity of smoking to price is much larger among lower income canadians in the context of recent behavioral models of smoking whereby higher taxes reduce unwanted smoking among price sensitive populations this finding suggests that cigarette taxes may not be as regressive as previously suggested finally we show that price increases on cigarettes do not increase and may actually decrease consumption of alcohol as a result smuggling of cigarettes may have raised consumption of alcohol as well

estimating the use and preservation values of national parks tourism resources using a contingent valuation method abstract the korean national parks authority has questioned whether natural resources have enough economic value to justify an increase in admission fee in the case of inadequate assistance from the government alternatively they also question whether the national parks have sufficient value to contribute to citizens welfare in order to receive continuing support from the government hence the purpose of this research is to estimate the use and preservation values of natural and or cultural resources in five distinctive national parks using a dichotomous choice contingent valuation method the empirical results show that natural and or cultural resources of the sample national parks possessed considerable use and preservation values outweighing current admission fees and maintenance costs per visitor thus these values provide enough justification for the national park authority to increase admission fees to maintain the quality of natural environment and avoid degrading natural resources in the event of no assistance by the government the findings may provide guidance to national park managers and practitioners who establish pricing policies the results also show that values of natural and or cultural resources were different across five distinctive national parks indicating the possibility of employing differential admission fees according to park characteristics

a comment on farmer education and farm efficiency a survey in a widely acknowledged study marlaine e lockheed dean t jamison and lawrence j lau presented a meticulous survey of studies investigating the effect of farmer education on farm efficiency in less developed countries in summarizing 18 different studies in 13 countries they concluded that education has a positive effect on efficiency and that on average 4 years of education results in a 7 4 improvement in output generally lockheed et al s study confirms a widely accepted view that education has a positive effect on farm productivity however a careful analysis of the empirical foundation of their study suggests the need for some skepticism about the conclusions drawn the estimated coefficients for the education variables in the production functions presented often are not statistically significant and in some cases show that education has a negative effect on farm efficiency for example if statistical significance is calculated at the 05 level only 22 of 39 equations 56 4 reported in lockheed et al s table 2 estimate a positive and statistically significant coefficient for the education variable the remaining 44 are either not significantly different from zero or are negative 2 separating the studies by geographic area reveals another interesting pattern in the studies namely how the expected result varies across regions latin america and asia are well represented in the sample with 13 and 22 studies respectively but only two of the studies are from africa 3 of the 13 latin american studies only three 23 1 are positive and significant at the 05 level for asia on the other hand over 77 3 17 of 22 show the expected result as for the two studies for africa one finds a negative effect of education on productivity and the other finds no significant effect this indicates that while there is evidence supporting the beneficial effect of education on productivity

governmental interventions and household behavior in a developing country anticipating the unanticipated consequences of social programs abstract estimates of the joint effects of governmental health education and family planning programs as well as sources of water on fertility child mortality and schooling are obtained from combined district level and household level data from rural india the estimates are used both to test the implications of a model of household decision making and to assess the effectiveness of the joint public provision of such services in shifting resources from increasing family size to augmenting human capital per person the results appear consistent with household optimizing behavior and suggest that reductions in the costs of medical services contraceptives and schooling and the improvement of water sources are mutually reinforcing alternatives for implementing the joint policy goals of reduced population growth and increased human capital formation

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

the nowhere children patriarchy and the role of girls in india s rural economy abstract this paper analyses the contribution that girls make to the rural economy in india through their involvement in the labour market as well as in household chores we model this in the context of the very different institutional and familial arrangements for girl children prevalent in different parts of india analysing the determinants of these activities within a multivariate probit model we find that the best possible outcome for girls is in districts with high female literacy because here the probability of schooling increases and the probability of work decreases less satisfactory but still acceptable outcomes arise in districts where the female labour participation is high our results also show that the presence of very young siblings in the household worsens the probability of girls going to school or even working the presence of older female siblings improves the chances of schooling while that of older male siblings increases the probability of girls doing household chores

self command in practice in policy and in a theory of rational choice an increasingly familiar occurrence for obstetricians is being asked by patients to withhold anesthesia during delivery the physician often proposes that a facemask be put beside the patient who may inhale nitrous oxide as she needs it but some determined patients ask that no such opportunity be provided if gas is available they will use it and they want not to be able to the request is interesting for decision theory and raises questions of ethics policy and physician responsibility even if the woman is merely making a mistake if she simply does not know how painful labor will be and how glad she will be even in retrospect if the pain is relieved but some women who make this request have had earlier deliveries during which they demanded anesthesia and received it they are acquainted with the pain they anticipate asking for relief and they want it withheld when they do they expect to regret afterwards any recourse to anesthesia this particular instance of attempted selfdenial has features that are special but many that are common the woman is so far as we know in good health physically and mentally she anticipates a transient period when her usual values and preferences will be suspended or inaccessible she has reasons for wanting to frustrate her own wishes at the critical time she needs cooperation she may ratify her choice afterward by expressing herself grateful that no anesthesia was offered even when requested there are ethical dilemmas and legal issues and there is conflict if say the husband disagrees with the physician in the delivery room about what his wife really wants

off farm labour allocation decisions in small scale rural households in zimbabwe the double hurdle model is used to analyse the off farm labour decisions of small scale agricultural household members in the shamva district of zimbabwe the approach permits the joint modelling of the decision to participate in the labour market and the decision regarding the amount of time allocated to work results indicate that a number of variables notably gender education and assets indeed have effects which are qualitatively and quantitatively different in terms of participation and hours worked overall the empirical analysis confirms the importance of individual characteristics such as gender and education and household farm characteristics e g land area accessible to the household productive assets remittances and the agricultural terms of trade in influencing the labour market decisions of rural household members

accounting for stochastic shadow values of time in discrete choice recreation demand models abstract in this paper a discrete choice recreation demand model that explicitly accounts for a stochastic shadow value of time function is proposed using data from a survey of san diego beach users the stochastic shadow value of time labor supply and beach choice are jointly estimated results from this joint estimation approach are compared with the familiar two step approach that estimates labor supply first and uses predicted values of time in the recreational site choice model the approaches produce markedly different welfare measures with the two step model which does not account for unobserved variability of time values predicting significantly higher values a monte carlo simulation illustrates how ignoring the stochastic nature of shadow value of time in discrete choice recreation demand models can bias model parameters and hence welfare estimates

searching for the opportunity cost of an individual s time a traditional assumption made in the literature is that the value of an individual s time spent in any activity is equal to his or her wage rate this result stems from the derivation of the value of leisure time in the context of the standard labor supply model this paper pre sents some reasons why the relationship be tween the wage rate and the value of time does not hold suggestions for what to do when the relationship breaks down and the investigator needs some value to impute to the individual are given in the final section of the paper

time and the recreational demand model in this paper a theoretically consistent approach to including time costs in recreational demand models is developed the demand model is conditional on the recreationist s labor market situation for individuals at corner solutions in the labor market utility maximization is subject to two constraints leading to a demand function with travel costs and travel time as independent variables with interior solutions in the labor market time is valued at the wage rate and combined with travel costs to produce one full cost variable in an illustration welfare measures based on the new model are estimated for a sample of sportfishermen

real options and demographic decisions abstract the theory of real options is used to incorporate the influence of uncertainty on demographic decision making the decision to have children is formulated as an investment using portfolio theory the timing of the decision to have a child is modelled as a real options decision with uncertainty affecting a woman s ability to exercise the option to wait in order to delay or space births an increase and reduction in uncertainty on this option is explored compared to the widely used net present value npv framework the real options approach roa better explains the process of demographic decision making in poor countries

income and employment effects of micro credit programmes village level evidence from bangladesh micro credit programmes having made their mark in providing credit and other development services to the poor in a non traditional way are able to make significant changes in a rural economy this article attempts to quantify the village level impacts of the three most important micro credit programmes of bangladesh namely grameen bank bangladesh rural advancement committee brac and bangladesh rural development board s brdb rd 12 project descriptive and econometric analyses show that these programmes have positive impacts on income production and employment particularly in the rural non farm sector also growth in self employment has been achieved at the expense of wage employment which implies an increase in rural wages the article emphasises that an upward shift in the labour demand curve is required for both improved productivity and wage gains on a sustainable basis which can only be supported through a structural transformation of the rural economy

non linearities in returns to participation in grameen bank programs abstract this paper studies the benefits of participation in micro finance programs where benefits are measured in terms of the ability to smooth the effect of seasonal shocks that cause consumption fluctuations it is shown that although membership in these programs is an effective instrument in combating inter seasonal consumption differences there is a threshold level of length of participation beyond which benefits begin to diminish returns from membership are modelled using an euler equation approach fixed effects non linear least squares estimation of parameters using data from 24 villages of the grameen bank suggests that returns to participation as measured by the ability to smooth seasonal shocks begin to decline after approximately two years of membership this implies that membership alone no longer has a mitigating marginal effect on seasonal shocks to per capita consumption after four years of participation such patterns suggest that the ability to smooth consumption as a function of l

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

access to water women s work and child outcomes abstractpoor rural women in the developing world spend considerable time collecting water do women living in places where more time is needed for water collection tend to participate less in income earning market based activities do the education outcomes of their children tend to be worse we use micro data for nine developing countries to help address these questions our primary aim is to describe the patterns in the data rather than to infer causality although we do treat the household level access to water as endogenous assuming that community level access is exogenous conditional on a wide range of geographic factors better access to water is not found to be associated with greater off farm paid work but is associated with less unpaid work for women in countries where substantial gender gaps in schooling exist both boys and girls enrollments also tend to be better

health nutrition and economic development the relationship between health and economic development is explored focusing on nutrition based health indicators the spotlight is placed on the inter related feedbacks between the influence of health on productivity on one hand and the influence of income on health status on the other disentangling causality in these relationships has preoccupied much of the literature we evaluate different empirical strategies that have been adopted and assess the results there is now a body of evidence based on careful empirical studies that demonstrates a causal relationship between health and labor productivity there is also evidence that at least among the very poor additional income is spent on improved nutrition there are two issues that have received little attention although we argue they are likely to be very important first measurement of health is discussed in detail evidence is presented on how taking into account differences in the extent of measurement error is critical for interpreting the impact of health on wages the same theme emerges in studies of the effect of income on health specifically calorie intake the key role of non linearities in these relationships is highlighted and we demonstrate that a good deal of the variation in estimates of income elasticities of demand for calories can be ascribed to the role of measurement and functional form authors

the effects of rural electrification on employment new evidence from south africa this paper estimates the impact of electrification on employment growth by analyzing south africa s mass roll out of electricity to rural households using several new data sources and two different identification strategies an instrumental variables strategy and a fixed effects approach i find that electrification significantly raises female employment within five years this new infrastructure appears to increase hours of work for men and women while reducing female wages and increasing male earnings several pieces of evidence suggest that household electrification raises employment by releasing women from home production and enabling microenterprises migration behavior may also be affected jel h54 l94

migration selectivity and the effects of public programs abstract a model of the spatial distribution of mobile heterogeneous agents is formulated to assess how a price change or program subsidy that is location specific affects the composition of local residents via selective migration and thus biases evaluations of the effectiveness of the program based on its local consequences longitudinal data from colombia are used to test the implications of migration selectivity the findings confirm the existence of selective migration suggesting that local subsidies to human capital attract high income but within income groups low fertility households and those with low human capital endowments these migration patterns are shown to be consistent with the dominance of endowment over tastes heterogeneity in the population under plausible behavioral assumptions

rainfall uncertainty and occupational choice in agricultural households of rural nepal abstract although agriculture is the main occupation in rural nepal evidence suggests that households strive to diversify their sources of income this paper investigates why this is the case using household data from the world bank and information on rainfall for the various rural districts of nepal we find that occupational choice is highly correlated to the uncertainty associated with historical rainfall patterns where the head is employed in agriculture other family members are less likely to choose agriculture as an occupation in districts where rain is more uncertain estimates indicate that for a 1 per cent increase in the coefficient of variation of rain there is a 0 61 per cent decrease in the probability of choosing the same occupation as the household head where the head is classified as self employed in agriculture the negative effect of rainfall uncertainty on occupational choice is less evident in households that have access to credit and in households with relatively high levels of

the impact of exogenous child mortality on fertility a waiting time regression with dynamic regressors in this paper the authors develop and implement an econometric methodology estimating a family specific exogenous component of life expectancy in order to determine the responsiveness of fertility to exogenous changes in child mortality they use a generalized waiting time regression model applied to length of life which is viewed as the output of a production process they allow for family specific heterogeneity in duration of life and for time varying explanatory variables the heterogeneity component retrieved from the production function estimation is used to estimate the impact of exogenous child mortality on a measure of fertility the data concern 1938 children from 311 families included in the 1976 malaysian family life survey this paper was previously published in econometrica chicago ill vol 51 no 3 may 1983 pp 731 49 excerpt

public infrastructure and private costs water supply and time allocation of women in rural pakistan the role of infrastructure in promoting development has been established it is noted that improvements in infrastructure increase the efficiency of production in this case study the authors investigated how the quality and quantity of infrastructure affect the time women in pakistan allocate to their various activities the focus is on the relationship between access to water at both the household and the community levels and the time allocation of rural women who have the primary responsibility for water collection findings indicate that changes in the availability of infrastructure affect time use both at the household and individual levels at the household level it is shown that poor infrastructure induces women to reduce their market oriented work and thus their contribution to household income moreover poor infrastructure also causes an increase in the total work burden of women and a decrease in leisure however with improved public water supply infrastructure the total time women spend in all activities would be lowered with a substitution of water collection and income generating activities in addition a public water supply system may also reduce the pathogen content of water thereby improving its quality this increase in quality will most likely to bring health and sanitary benefits

taxation regulation and addiction a demand function for cigarettes based on time series evidence this work analyzes the effects of prices taxes income and anti smoking regulations on the consumption of cigarettes in california a 25 cent per pack state tax increase in 1989 enhances the usefulness of this exercise analysis is based on monthly time series data for 1980 through 1990 results show a price elasticity of demand for cigarettes in the short run of 0 3 to 0 5 at mean data values and 0 5 to 0 6 in the long run we find at least some support for two further hypotheses that antismoking regulations reduce cigarette consumption and that consumers behave consistently with the model of rational addiction

evaluating the effects of optimally distributed public programs child health and family planning interventions this paper develops and tests an optimizing model determining the distribution of family planning and health subsidies across heterogeneous households and assesses the biases in cross area estimates of the health effects of such subsidies due to public resource optimization the model incorporates both health externalities and the endogenous response of the size of the recipient population to program subsidies longitudinal data describing child health and publicly provided family planning and health programs in 20 barrios in laguna province in the philippines are used to estimate the effects of such programs on child health and the relationships between the distribution of the programs and preprogram health levels the impact of a program on a particular childs health status is viewed as dependent upon the childs length of exposure to the program a basic feature of the model is the presence of health externalities which is shown to be sufficient along with plausible features of household behavior to make selective subsidization of fertility control either alone or in combination with health investment subsidies pareto efficient the model suggests that subsidization of fertility control is likely to be pareto efficient in the presence of health or human capital externalities when human capital and family size are gross substitutes and or when any per child human capital subsidies may substitute for direct subsidies to health investment and an equalizing distribution of the subsidies the highest family planning subsidies to the lowest health recipient households is efficient when both health and family planning subsidies are used fertility control subsidies minimize the subsidy burden for donors and are highest when total subsidy expenditures per child are greatest
