snap benefits and crime evidence from changing disbursement schedules in this paper we study the effects of the timing of nutritional aid disbursement on crime using two main sources of variation a a policy change in illinois that substantially increased the num

measuring the impact of water supply interruptions on household welfare water scarcity frequently leads to a need for rationing the choice of an adequate rationing method should be based on the impact on consumer welfare that is produced by each rationing plan some rationing schemes such as the frequently used supply interruption method can be regarded as changes in the characteristics of the good in this case time availability that do not modify the pre set consumer budget under the standard theoretical restrictions on consumer behavior compensating or equivalent variations surpluses cannot be used to identify the impacts of these methods on household welfare in this paper we propose a set of sufficient conditions with respect to the utility function that allows for the evaluation of the compensating or equivalent variations surpluses associated with changes in goods quality even if those goods are considered to be essential for consumers we use these conditions to compare the welfare losses associated with the water supply cuts implemented in seville spain to those that would result if water was instead rationed using price changes

the effects of the macroeconomy and welfare reform on food stamp caseloads since 1994 there has been an unprecedented decline in the number of people receiving food stamp benefits from a record high of 27 5 million in 1994 the number of food stamp recipients fell over 30 to 18 0 million by mid 1999 during this period the united states has experienced the third longest economic expansion of the twentieth century this has resulted in a dramatic growth of new jobs and the lowest unemployment rate in a generation simultaneously the welfare system has undergone a major transformation beginning in the early 1990s when many states made changes to their welfare programs through federal waivers from aid to families with dependent children afdc requirements the personal responsibility and work opportunity reconciliation act of 1996 prwora furthered these changes by replacing afdc where states contributions were matched by the federal government with a block grant program called temporary assistance for needy families tanf prwora introduced new rules on tanf recipients such as terminal time limits work requirements and personal responsibility measures it also directly changed the food stamp program by ending the eligibility of some recipients and reducing average benefit levels at the same time innovative changes in the delivery of food stamp benefits have been taking place with the introduction of electronic benefit trans

would harassing drug users work when harassed users adopt new ways of transaction supply changes in predictable ways this linkage between demand and supply can explain a number of puzzling consequences of the decriminalization of marijuana and the war on heroin and cocaine

do husbands and wives pool their resources evidence from the united kingdom child benefit common preference models of family behavior imply income pooling a restriction on family demand functions such that only the sum of husband s income and wife s income affects the allocation of goods and time testing the pooling hypothesis is difficult because most family income sources are not exogenous to the allocations being analyzed in this paper we present an alternative test based on a natural experiment a policy change in the united kingdom that transferred a substantial child allowance to wives in the late 1970s using family expenditure survey data we find strong evidence that a shift toward greater expenditures on women s clothing and children s clothing relative to men s clothing coincided with this income redistribution

discrete choice experiments in developing countries willingness to pay versus willingness to work a concern when conducting stated preference valuation studies in rural developing or very low income contexts is the use of monetary willingness to pay wtp estimates in circumstances where cash incomes are extremely low a significant proportion of the population are not engaged in waged labour and the exchange of goods or services is augmented through barter or work exchange the role of money is likely to be different from that within an urban developed setting as such ability to pay using money may be impaired and downwardly biased when compared with other mediums of exchange in recognition of this several studies have used hypothetical labour contributions as payment vehicles and a common finding is that households are more often willing to contribute labour than they are money in this paper we present the results of a split sample dce using money and labour contributions as payment vehicles for improved drinking water quality in kandal province cambodia we find little differences between the payment vehicles in terms of attribute non attendance marginal utilities of attributes or derived welfare values we argue that this provides support for the use of wtp in rural developing areas where there are functioning labour markets

dietary effects of the food stamp program based on data from the 1979 80 survey of food consumption in low income households this paper estimates the effects of changes in cash income and the food stamp benefit on household nutrient availability while controlling for two potential sources of selection bias the major finding of the empirical analysis is that the estimated dietary effects of changes in food stamp benefits are considerably larger than those resulting from changes in cash income with estimates of the ratios of the mpc for the food stamp benefit to the cash income mpc ranging from three to seven across nutrients no significant evidence of selection bias was found and the estimated dietary effects of food stamp benefits from the selection bias models are similar to those from the basic model estimated by ordinary least squares regression

consumption versus expenditure previous authors have documented a dramatic decline in food expenditures at the time of retirement we show that this is matched by an equally dramatic rise in time spent shopping for and preparing meals using a novel data set that collects detailed food diaries for a large cross section of u s households we show that neither the quality nor the quantity of food intake deteriorates with retirement status we also show that unemployed households experience a decline in food expenditure and food consumption commensurate with the impact of job displacement on permanent income these results highlight how direct measures of consumption distinguish between anticipated and unanticipated shocks to income whereas measures of expenditures obscure the distinction

the effects of benefit timing and income fungibility on food purchasing decisions among supplemental nutrition assistance program households the supplemental nutrition assistance program snap is the largest nutritional safety net in the united states prior research has found that participants have higher consumption shortly after receiving their benefits followed by lower consumption towards the end of the benefit month known as the snap benefit cycle this consumption pattern has been found to have negative effects on beneficiaries we hypothesize two behavioral responses of snap participants may work in tandem to drive much of the cycle 1 short run impatience a higher preference to consume today and 2 fungibility of income the degree of substitutability between a snap dollar and a cash dollar using data from the national food acquisition and purchase survey foodaps a newly developed nationally representative survey of daily food acquisitions by snap households we find evidence of both behavioral responses however the degree of short run impatience and fungibility of income is found to differ significantly across poverty levels and use of grocery lists to plan food purchases snap households could gain from food purchase planning education

model selection for the mixed logit with bayesian estimation in this paper the mixed logit ml using bayesian methods was employed to examine willingness to pay wtp to consume bread produced with reduced levels of pesticides so as to ameliorate environmental quality from data generated by a choice experiment model comparison used the marginal likelihood which is preferable for bayesian model comparison and testing models containing constant and random parameters for a number of distributions were considered along with models in preference space and wtp space as well as those allowing for misreporting we found strong support for the ml estimated in wtp space little support for fixing the price coefficient a common practice advocated and adopted in the environmental economics literature and weak evidence for misreporting

estimating the willingness to pay for reliable electricity supply a choice experiment study abstract this research examines households willingness to pay wtp for an improved electricity service households stated wtp is estimated using the choice experiment ce method the data used in the estimations come from 350 in person interviews conducted during the period 5 22 august 2008 in north cyprus compensating variation cv estimates for a zero outage scenario are calculated using the parameter estimates from the mixed logit ml model these are 6 65 ytl turkish lira per month 3 02 usd for summer and 25 83 ytl per month 11 74 usd for winter in order to avoid the cost of outages households are willing to incur a 3 6 and a 13 9 increase in their monthly electricity bill for summer and winter respectively the wtp per hour unserved is 0 28 ytl 0 13 usd for summer and 1 08 ytl 0 49 usd for winter a preliminary cost benefit analysis indicates that the annualized economic benefits are approximately 42 7 million ytl 19 4 million usd for the residential sector this would justify an investment in additional generation capacity of approximately 268 mw which is far more than that which is needed to eliminate the service reliability problem

illegal drug use and employment this article investigates the relationship between employment and the use of marijuana and cocaine for males in national longitudinal survey of youth data from 1984 and 1988 previous studies yielding mixed evidence may have inadequately accounted for the simultaneity between drug consumption and employment i implement an instrumental variable procedure that identifies drug use with variables that are empirically unrelated to employment including the regional cocaine price and a state marijuana decriminalization indicator results indicate that the use of each drug substantially reduces the likelihood of employment exogeneity tests reveal that standard probit estimates are severely biased toward zero

the demand for illicit drugs i introduction illicit drug use and alcohol abuse imposes significant costs on society and on the individual users these costs include increased crime health problems and employment problems because of these considerable costs government at all levels has made drug control and the control of alcohol abuse important priorities the federal government has undertaken an aggressive program of interdiction of drug shipments and eradication of drug crops in the field the federal government and the state governments have also increased their criminal justice efforts in analyzing the effect of government drug control programs economists have applied the conventional supply and demand model to illicit drug markets the model includes a demand function that is downward sloping with respect to price and a supply function that is upward sloping or horizontal with respect to price drug programs like interdiction and drug sanctions are assumed to reduce supply and raise equilibrium price other policy options such as some form of drug legalization could increase supply and reduce equilibrium price the effect of these policies on equilibrium quantity is dependent on the elasticity of demand and on whether demand shifts since not much is known about drug price elasticities the potential effects of various drug control policies remain a speculative exercise the purpose of this paper is to estimate the effects of alcohol and drug prices on alcohol use and drug participation both own price and cross price effects are estimated there are few prior empirical studies of the effect of drug prices because data have been difficult to acquire this paper makes use of newly available data on drug prices and is the first paper to link these data to a nationally representative drug use data set of 49 802 individuals estimates of drug price elasticities are important empirical evidence that drug sales can be characterized by market forces drug price elasticities are also important in estimating the likely impact of policies that affect drug prices and in estimating the effects of drug prohibition cross price elasticities are important to estimate since they suggest the likely effects of policies such as an increase in alcohol taxes on illicit drug participation and the effects of marijuana decriminalization on alcohol cocaine and heroin use ii prior studies while there are a number of prior studies of the effects of alcohol prices and policies there are few prior studies of drug prices and polices the reason for so few prior drug studies is the limited amount of data on drug prices and the limited options for linking these data to an individual record by residential area this study uses a new data set of cocaine and heroin prices from the drug enforcement agency that was linked to individual records by the office of applied studies at the substance abuse and mental health services administration leung and phelps 1993 provide a review of a number of recent alcohol demand studies the empirical literature provides considerable evidence that shows increasing the price of alcoholic beverages to decrease alcohol use alcohol demand studies generally estimate price elasticities for beer wine and spirits separately most studies employ aggregate data but a few use individual data studies using aggregate data find price elasticities for beer from about 2 to about 1 0 for wine from about 3 to about 1 8 and for spirits from about 3 to about 1 8 studies using individual data estimate price elasticities for beer from about 5 to about 3 0 for wine at about 5 and for spirits from about 5 to about 4 0 the few prior studies of the effect of decriminalization on marijuana use generally find that marijuana decriminalization has no effect on participation pacula 1994 thies and register 1993 dinardo and lemieux 1992 and johnston o malley and bachman 1981 all used samples of young people and found no effect of marijuana decriminalization

designing conjoint choice experiments using managers prior beliefs abstract the authors provide more efficient designs for conjoint choice experiments based on prior information elicited from managers about the parameters and their associated uncertainty the authors use a bayesian design procedure that assumes a prior distribution of likely parameter values and optimizes the design over that distribution the authors propose a way to elicit prior information from managers and show in monte carlo studies that the procedure provides more efficient designs than the current procedures the authors provide an empirical application in which they elicit prior information on the parameter values and the associated uncertainty from managers here the bayesian design provides 30 50 lower standard errors of the estimates and an expected predictive validity that is approximately 20 higher

asking for individual or household willingness to pay for environmental goods implication for aggregate welfare measures the aggregate welfare measure for a change in the provision of a public good derived from a contingent valuation cv survey will be higher if the same elicited mean willingness to pay wtp is added up over individuals rather than households a trivial fact however once respondents are part of multi person households it becomes almost impossible to elicit an uncontaminated wtp measure that with some degree of confidence can be aggregated over one or the other response unit the literature is mostly silent about which response unit to use in wtp questions and in some cv studies it is even unclear which type has actually been applied we test for differences between individual and household wtp in a novel web administered split sample cv survey asking wtp for preserving biodiversity in old growth forests in norway two samples are asked both types of questions but in reverse order followed by a question with an item battery trying to reveal why wtp may differ we find in a test between samples that the wtp respondents state on behalf of their households is not significantly different from their individual wtp however within the same sample household wtp is significantly higher than individual wtp in particular if respondents are asked to state individual before household wtp our results suggest that using individual wtp as the response unit may overestimate aggregate wtp thus the choice of response format needs to be explicitly and carefully addressed in cv questionnaire design and further research in order to avoid the risk of unprofitable projects passing the benefit cost test

is there a daily discount rate evidence from the food stamp nutrition cycle abstract quasi hyperbolic discounting predicts impatience over short run tradeoffs i present a direct non laboratory test of this implication using data on the nutritional intake of food stamp recipients caloric intake declines by 10 to 15 percent over the food stamp month implying a significant preference for immediate consumption these findings constitute a rejection of the permanent income hypothesis and are extremely difficult to reconcile with exponential discounting the data support an explanation based on time preference and reject several alternative explanations including highly elastic intertemporal substitution i explore implications for the optimal timing of transfer payments under alternative assumptions about preferences

does it matter when a power outage occurs a choice experiment study on the willingness to pay to avoid power outages using a choice experiment survey the marginal willingness to pay wtp among swedish households for reductions in power outages is estimated the results from the random parameter logit estimation indicate that the marginal wtp increases with the duration of the outages and is higher if the outages occur during weekends and during winter months moreover the random parameter logit model allows us to estimate a sample distribution of wtp and we find a significant unobserved heterogeneity in some of the outage attributes given that households have negative welfare effects from outages it is important that policy makers consider these negative impacts on household utility when regulating the swedish electricity market

long run impacts of childhood access to the safety net a growing economics literature establishes a causal link between in utero shocks and health and human capital in adulthood most studies rely on extreme negative shocks such as famine and pandemics we are the first to examine the impact of a positive and policy driven change in economic resources available in utero and during childhood in particular we focus on the introduction of a key element of the u s safety net the food stamp program which was rolled out across counties in the u s between 1961 and 1975 we use the panel study of income dynamics to assemble unique data linking family background and county of residence in early childhood to adult health and economic outcomes the identification comes from variation across counties and over birth cohorts in availability of the food stamp program our findings indicate that the food stamp program has effects decades after initial exposure specifically access to food stamps in childhood leads to a significant reduction in the incidence of metabolic syndrome obesity high blood pressure and diabetes and for women an increase in economic self sufficiency overall our results suggest substantial internal and external benefits of the safety net that have not previously been quantified

paycheque receipt and the timing of consumption this article examines the consumption response to monthly paycheque receipt since the amount and arrival date of paycheques are known in advance the receipt of a paycheque does not coincide with the receipt of new information under the basic rational expectations life cycle permanent income hypothesis household consumption should not respond to paycheque arrival using data from the uk s family expenditure survey this article finds that household consumption is excessively sensitive to paycheque receipt the results cannot be explained by any underlying monthly expenditure fluctuations common to all households the presence of liquidity constraints as measured by wealth and age can account for the excess sensitivity results

the effects of male and female labor supply on commodity demands we examine the effects of male and female labor supply on household demands and present a simple and robust test for the separability of commodity demands from labor supply using data on individual households from six years of the uk fes we estimate a demand system for seven goods which includes hours and participation dummies as conditioning variables allowance is made for the possible endogeneity of these conditioning labor supply variables we find that separability is rejected furthermore we present evidence that ignoring the effects of labor supply leads to bias in the parameter estimates

unemployment insurance and disability insurance in the great recession social security disability insurance ssdi awards rise during recessions if marginal applicants are able to work but unable to find jobs countercyclical unemployment insurance ui benefit extensions may reduce ssdi uptake exploiting ui extensions in the great recession as a source of variation we find no indication that expiration of ui benefits causes ssdi applications and can rule out effects of meaningful magnitude a supplementary analysis finds little overlap between the two programs recipient populations only 28 of ssdi awardees had any labor force attachment in the prior calendar year and of those only 4 received ui

aching to retire the rise in the full retirement age and its impact on the social security disability rolls abstract the social security amendments of 1983 reduced the generosity of social security retired worker benefits in the u s by increasing the program s full retirement age from 65 to 67 and increasing the penalty for claiming benefits at the early retirement age of 62 these changes were phased in gradually so that individuals born in or before 1937 were unaffected and those born in 1960 or later were fully affected no corresponding changes were made to the program s disabled worker benefits and thus the relative generosity of social security disability insurance ssdi benefits increased in this paper we investigate the effect of the amendments on ssdi enrollment by exploiting variation across birth cohorts in the policy induced reduction in the present value of retired worker benefits our findings indicate that the amendments significantly increased ssdi enrollment since 1983 with an additional 0 6 of men and 0 9 of women between the ages of 45 and 64 receiving ssdi benefits in 2005 as a result of the changes our results further indicate that these effects will continue to increase during the next two decades as those fully exposed to the reduction in retirement benefit generosity reach their fifties and early sixties

the monthly food stamp cycle shooping frequency and food intake decisions in an endogenous switching regression framework mean food spending by food stamp households peaks sharply in the first three days after benefits are received for those who conduct major grocery shopping trips only once per month 42 of all food stamp households mean food energy intake drops significantly by the fourth week of the month for the remaining households intake remains steady over the course of the month these patterns motivate an empirical model that simultaneously accounts for the shopping frequency and food intake decisions over time results have implications for policies that may affect the frequency of grocery shopping by food stamp households

model selection and misspecification in discrete choice welfare analysis this study extends the work by herriges and kling 1997 to further evaluate the impact of discrete choice modelling techniques on welfare measures particularly we evaluate the performance of the increasingly popular mixed logit model and the computational strategy for deriving discrete choice welfare measures our simulation results show that model misspecification can have profound effects on welfare measures in general the flexible mixed logit model performs relatively well in the presence of misspecification however when the nesting structure can be appropriately identified via statistical tests and a priori knowledge experience the nested logit model provides more reliable welfare measures than the mixed logit model

supplier choice and wtp for electricity attributes in an emerging market the role of perceived past experience environmental concern and energy saving behavior abstract this study analyzes customers preferences and their willingness to pay wtp for certain service attributes in an electricity supplier choice context specifically a stated preference choice experiment is conducted in the canary islands residential market where limited competition exists preferences for different electricity suppliers and three level of service attributes are investigated namely supply reliability share of renewable energies and availability of a complementary energy audit service the results might be interpreted as an indication of different aspects new firms need to consider if they plan to enter in the market there is an opportunity for new companies to establish in the market though evidence of brand loyalty to the current company and or significant switching costs are also found especially in the case of older people regarding the estimated wtp several results should be highlighted first customers who have experienced more serious outages in the past tend to show a higher wtp to reduce the outage frequency second highly educated respondents those who state a great concern for the greenhouse gases ghg emissions and those who carry out energy saving actions in their homes exhibit a larger wtp for renewable energies this empirical evidence provides useful information for authorities responsible for energy policy design

estimation in a class of simultaneous equation limited dependent variable models estimation in a class of simultaneous equation limited dependent variable models is considered the minimum chi squared method is used to compare the asymptotic relative efficiency of marginal and new conditional maximum likelihood estimators for this class of models efficient minimum chi squared estimation procedures are described a two step algorithm based on a conditional maximum likelihood estimator provides a natural framework for both computing a linearized and locating the joint maximum likelihood estimator the unimodality of the simultaneous equation tobit likelihood function is proved and this model is used to illustrate the empirical application of some of the estimators considered in the paper the relative efficiency of these estimators in the simultaneous equation tobit model is examined in a set of monte carlo experiments many applications of microeconomic theory to individual data face the joint problems of censoring and simultaneity in particular the dependent variable under investigation may not be continuously observed and some of the conditioning variables representing the outcome of other decisions by the individual may be simultaneously determined smith and blundell 1986 developed an asymptotically efficient test for exogeneity or simultaneity in the simultaneous equation tobit model as a byproduct a conditional maximum likelihood estimator was obtained which is consistent under the alternative hypothesis of simultaneity nelson and olsen 1978 amemiya 1978 1979 and heckman 1978 consider a number of consistent marginal maximum likelihood estimators based on marginal maximum likelihood estimators of the reduced form parameters for the probit and tobit models in contrast the estimator derived from smith and blundell 1986 is based on the corresponding conditional maximum likelihood estimators this paper is concerned with estimation in a class of simultaneous limited dependent variable regression models which includes the simultaneous probit and tobit models as special cases analogous marginal and conditional maximum likelihood estimators to those of nelson and olsen 1978 amemiya 1978 1979 heckman 1978 and smith and blundell 1986 are derived and other new estimators are suggested the minimum chi squared approach discussed by ferguson 1958 malinvaud 1970 and rothenberg 1973 is used to compare the asymptotic relative efficiency of various estimators considered a simple two step algorithm based on the conditional maximum likelihood

households willingness to pay for water service attributes water consumption and disposal are often taken for granted as essential services with required levels of service quality yet little is known about how much consumers are willing to pay for specific service levels as customers in many countries face changing levels of water availability especially shortages linked possibly to climate change and limited catchment capacity the need to assess the value and hence benefit to society of varying service levels and prices in an effort to secure the provision of and disposal of water has risen on public agendas in an attempt to establish how much customers are willing to pay for specific levels of service we use a series of stated choice experiments and mixed logit models to establish the willingness to pay to avoid interruptions in water service and overflows of wastewater differentiated by the frequency timing and duration of these events the empirical evidence is an important input into the regulatory process for establishing service levels and tariffs as well as useful planning information for agencies charged with finding cost effective ways of delivering services at prices that customers deem to be value for money

alcoholism work and income this article reports on an empirical analysis of the relationships between alcoholism and income and working we show that the relationships between alcoholism and labor market success have important age or life cycle dimensions we present evidence that alcoholism may affect income more by restricting labor market participation than by affecting the wages of workers finally we demonstrate that the effects of alcoholism on earnings depend on the extent to which one controls for other covariates associated with alcoholism as such we suggest that there may be important indirect as well as direct effects of alcoholism on labor market success

inside the war on poverty the impact of food stamps on birth outcomes this paper evaluates the health impacts of a signature initiative of the war on poverty the introduction of the modern food stamp pro gram fsp using variation in the month fsp began operating in each u s county we find that pregnancies exposed to fsp three months prior to birth yielded deliveries with increased birth weight with the largest gains at the lowest birth weights we also find small but statistically insig nificant improvements in neonatal mortality we conclude that the sizable increase in income from fsp improved birth outcomes for both whites and african americans with larger impacts for african american mothers n this paper we evaluate the health consequences of a sizable improvement in the resources available to ameri ca s poorest in particular we examine the impact of the food stamp program fsp which in 2007 provided 34 billion in payments to about 13 million households on infant health our paper makes two distinct contributions first although the goal of the fsp is to increase the nutri tion of the poor few papers have examined its impact on health outcomes second building on work by hoynes and schanzenbach 2009 we argue that the fsp treatment represents an exogenous increase in income for the poor our analysis therefore represents a causal estimate of the impact of income on health an important topic with little convincing evidence due to concerns about endogeneity and reverse causality currie 2009 we use the natural experiment afforded by the nation wide rollout of the modern fsp during the 1960s and early 1970s our identification strategy uses the sharp timing of the county by county rollout of the fsp which was initially constrained by congressional funding authorizations and ultimately became available in all counties by 1975 speci fically we use information on the month the fsp began operating in each of the roughly 3 100 u s counties and examine the impact of the fsp rollout on mean birth weight low birth weight gestation and neonatal mortality throughout the history of the fsp the program para meters have been set by the u s department of agriculture usda and are uniform across states in the absence of the state level variation often leveraged by economists to eval uate transfer programs previous fsp research has typically resorted to strong assumptions as to the comparability of fsp participants and eligible nonparticipants currie 2003 not surprisingly the literature is far from settled as to what casual impact if any the fsp has on nutrition and health hoynes and schanzenbach 2009 use this county rollout to examine the impact of the fsp on food consumption using the psid they found that the introduction of the fsp increased total food spending and decreased out of pocket food spending importantly consistent with the predictions of canonical microeconomic theory the magnitude of the increase in food expenditures was similar to an equivalent sized income transfer implying that most recipient house holds were inframarginal that is they would spend more on the subsidized good than the face value of the in kind transfer as one of the largest antipoverty programs in the united states comparable in cost to the earned income tax credit eitc and substantially larger than temporary assistance to needy families tanf understanding fsp effects is valuable both in its own right and for what it reveals about the relationship between income and health 1

exogenous shocks and related goods drinking and the legalisation of marijuana abstract the paper uses the substitutability between goods to model the transmission to other products of a consumption shock to one product the framework is used to analyse the impact on drinking of legalisation of marijuana for all types of consumers for example the results indicate that legalisation would lead to approximately a 4 increase in marijuana consumption while beer wine and spirits consumption would fall by 1 2 and almost 4 respectively

who feels the calorie crunch and when the impact of school meals on cyclical food insecurity abstract monthly welfare programs such as the supplemental nutrition assistance program snap produce consistent cycles of expenditure and consumption among recipients food insecurity health status crime poor behavior and test scores track these cycles this paper leverages new data from the usda the foodaps survey to better understand these cycles in three ways first i find that expenditure and consumption cycles are correlated within households a fact not previously established second i study diet quality over the benefit month and find that it worsens potentially compounding the harmful consequences of cyclical food insecurity third i find that kids bear less of the burden of the consumption cycle than adults and that much of this difference may be driven by school meal programs this finding suggests large potential gains in child welfare from expanding summer meal programs

the value of household water service quality in lahore pakistan most existing literature focuses on the benefits of establishing basic drinking water access for unserved populations the extensive water supply margin in contrast this article examines the intensive margin the benefits of improving water service to under served households a growing population in developing country cities we use contingent valuation to estimate willingness to pay wtp for improved piped water quality and reductions in supply interruptions among a sample of 193 households in lahore pakistan the distribution of wtp is described using parametric and non parametric models results indicate that households in lahore are willing to pay about 7 50 to 9 per month for piped water supply that is clean and drinkable directly from the tap comparable to the monthly cost of in home water treatment and about three to four times the average monthly water bill for sample households using piped water estimates of wtp for reducing supply interruptions are both smaller and more difficult to interpret since a significant fraction of the estimated wtp distribution for supply improvements is negative all of our wtp estimates are well below 4 of monthly household income the world bank s benchmark upper bound for affordable water service

the impact of stricter criteria for disability insurance on labor force participation this paper studies the effect of a large scale policy change in the austrian disability insurance program which tightened eligibility criteria for men above a certain age using administrative data on the universe of austrian private sector employees the results of difference in difference regressions suggest a substantial and statistically significant decline in disability enrollment of 6 to 7 4 percentage points and an increase in employment of 1 6 to 3 4 percentage points the policy change had important spillover effects into the unemployment and sickness insurance program specifically the share of individuals receiving unemployment benefits increased by 3 5 to 3 9 percentage points and the share receiving sickness insurance benefits by roughly 0 7 percentage points

risk aversion and willingness to pay for energy efficient systems in rental apartments abstract this paper uses a random utility model to estimate consumers valuation of energy efficient insulation and ventilation systems in rental apartments given consumers limited experience in residential buildings and the perceived uncertainty about their comfort benefits and resulting energy savings these relatively new technologies might be undervalued by risk averse consumers using the concept of certainty equivalence this paper proposes a model to assess the consumers risk aversion for adopting energy efficient systems these systems are treated as risky assets while conventional commodities are assumed to be risk free the curvature of the utility function is interpreted as a measure of aversion to perceived risks as opposed to explicit risks measured by observed variances the proposed formulation is applicable in stated preference data with qualitative variables the model is applied to data from a choice experiment conducted among 264 apartment tenants in switzerland the estimated curvatures reject the risk neutrality hypothesis the range of the estimated risk premiums suggests that risk considerations remain a central issue in dealing with energy efficiency in residential buildings the analysis also indicates that assuming same risk attitudes toward new and conventional systems could bias the estimates of the willingness to pay especially when the system is comprised of several components

3rd of tha month do social security recipients smooth consumption between checks this paper examines the response of consumption expenditures to the monthly receipt of social security checks since the amount and arrival date of these checks are known to the recipients the basic life cycle permanent income hypothesis lcpih predicts that consumption should not respond to the receipt of these checks using daily diary data from the consumer expenditure survey this paper finds evidence that both the dollar amount and probability of expenditures increase immediately following the receipt of this check most relevant to testing the lcpih categories of instantaneous consumption expenditure such as food away from home increase on the check arrival date the response is found primarily amongst households for whom social security is the primary source of income however the magnitude of the estimated responses are relatively small and do not suggest that the utility losses are large from this non smoothing behavior this abstract was borrowed from another version of this item
