sequential labor decisions under uncertainty an estimable household model of west african farmers this paper reports estimates of the structural parameters of a stochastic control model that describcs the labor decisions of small farmers in burkina faso west africa the focus of the estimation is on measuring flexibility in production and intertemporal substitutability in consumption full information maximum likelihood estimates of the primitive parameters of the model are computed even though optimal labor decision rules cannot be derived analytically vuong s non nested model specification test shows that this method yields parameter estimates that are superior to those derived by assuming that farmers solve a deterministic control problem the low levels of agricultural labor effort commonly observed in the survey area are shown to be a consequence both of the low productivity of labor in archaic rainfed agriculture and of farmers awareness that in the absence of a labor market overly ambitious production plans lead to seasonal manpower constraints to meet rainfed farmers concerns agricultural research institutes and extension services should factor flexibility into their research agendas

rational household labor supply traditionally household behavior is derived from the maximization of a unique utility function in this paper we propose an alternative approach in which the household is modeled as a two member collectivity taking pareto efficient decisions the consequences of this assumption are analyzed in a three good model in which only total consumption and each member s labor supply are observable if the agents are assumed egoistic i e they are only concerned with their own leisure and consumption it is possible to derive falsifiable conditions upon household labor supplies from both a parametric and nonparametric viewpoint if alternatively agents are altruistic restrictions obtain in the nonparametric context useful interpretation stems from the comparison with the characterization of aggregate demand for a private good economy

to remit or not to remit that is the question a remittance field experiment we conduct a remittance field experiment among salvadoran migrants in the metro dc area migrants need to decide whether or not to remit funds to a recipient in el salvador and if so how much we maintain a 2x2 design in which the remittance budget has a value of 400 or 200 and the remitted funds arrive as cash or grocery vouchers that are non transferable and applicable to basic necessities that do not include alcohol and cigarettes each migrant is randomly allocated to one of the resulting four treatments we test across these treatments whether control over remittance spending in the form of grocery vouchers affects remittance behavior we find the following our quantitative findings suggest that migrants prefer a remittance to arrive as cash than as groceries when stakes are high this result is robust to inclusion of a wide set of covariates and is consistent with a conceptual framework in which migrants have preferences over how recipients spend remittances our qualitative findings suggest that migrants integrate amounts sent in the experiment with the external environment for sending remittances we explore the mechanisms underlying the main effect and find that migrants who more recently sent a remittance and in certain specifications male migrants exhibit a greater preference for cash some implications of our findings are discussed

a test for moral hazard in the labor market contractual arrangements effort and health moral hazard plays a central role in many models depicting contractual relationships involving worker effort the authors show how time series information on worker health consumption and work time can be used to measure the effort effects of payment schemes estimates from longitudinal data describing farming rural households indicate that time wage payment schemes and share tenancy contracts reduce effort compared to piece rate payment schemes and on farm employment the evidence also indicates consistent with moral hazard that the same workers consume more calories under a piece rate payment scheme or in on farm employment than when employed for time wages copyright 1994 by mit press

a utility consistent combined discrete choice and count data model assessing recreational use losses due to natural resource damage abstract a two stage budgeting approach can often be taken when analyzing consumer choice situations in this paper we examine the particular situation where a consumer makes purchases of a discrete commodity of which there are a number of brands in the first stage the consumer decides how many purchases to make in the second stage the consumer decides how to allocate these purchases across brands our econometric approach to this type of situation uses a utility consistent combined discrete choice and count data model the second stage which is specified as a multinomial choice model produces a price index for the commodity which is used to estimate the first stage which is specified as a count data model we apply the model to recreational demand behavior in alaska in order to estimate the welfare losses suffered by recreational users due to the exxon valdez oil spill these results may provide useful input to government agencies attempting to estimate the appropriate level of taxes fines or regulations for deterring damage to the environment

when are forest visits valued the most an analysis of the seasonal demand for forest recreation in poland while the demand for forest recreation has been a topic covered in many studies little attention has been paid so far to seasonal demand in a forest context the seasonal analysis is particularly interesting because of inter temporal change in forest attributes throughout the year which can influence trip taking behavior in this paper the model of seasonal forest visitation is developed to provide a richer understanding of the role played by seasonal fluctuation on a distribution of forest social benefits the analysis is based on an on site survey conducted in four forests in poland results show that the most valuable forest trips are those taken in fall and that seasonal trips are separable

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

using revealed preferences to estimate the value of travel time to recreation sites the opportunity value of travel time vtt is one of the most important elements of the total cost of recreation day trips and arguably the most difficult to estimate most studies build upon the theoretical framework proposed by becker 1965 by using a combination of revealed and stated preference data to estimate a value of time which is uniform in all activities and under all circumstances this restriction is relaxed by deserpa s 1971 model which allows the value of saving time to be activity specific we present the first analysis which uses actual driving choices between open access and toll roads to estimate a vtt specific for recreation trips thereby providing a value which conforms to both becker s and deserpa s theoretical models using these findings we conduct a monte carlo simulation to identify generalizable results for subsequent valuation studies our results indicate that 3 4 of the wage rate provides a reasonable approximation of the average vtt for recreation trips while the commonly implemented assumption of 1 3 of the wage rate generates downward biased results

value of time speeding behavior and gasoline prices abstract value of time vot is a key parameter in economics and policy this paper presents an alternative method to estimate vot by analyzing an hourly dataset on drivers speeding behavior as a function of the gasoline price our identification strategy is novel as it is based on the intensive margin in comparison previous studies reveal vot on the extensive margin but choice alternatives have multiple attributes thereby potentially confounding estimates consistent with the range of the prior literature we find a vot of about 50 of the wage rate and analyze sources of bias from accidents and traffic tickets these bias functions suggest that previous stated preference vot estimates are likely downward whereas previous revealed preference estimates are likely upward biased

savings in transnational households a field experiment among migrants from el salvador abstract we implemented a randomized field experiment that tested ways to stimulate migrants savings in their origin country we find that migrants value opportunities to exert greater control over financial activities in their home countries we offered u s based migrants bank accounts in el salvador randomly varying migrant control over el salvador based savings by offering different accounts across treatments migrants offered the greatest degree of control accumulated the most savings impacts likely represent increases in total savings there is no evidence that savings increases were simply reallocated from other savings mechanisms enhanced control over home country savings does not affect remittances sent home

combining contingent valuation and travel cost data for the valuation of non market goods the travel cost method tcm has long been used to infer the economic value of nonmarket resources and public goods more recently contingent valuation cvm survey methods have gained popularity for eliciting these values here cvm survey responses are combined with tcm data on actual market behavior to estimate jointly both the parameters of the underlying utility function and its corresponding ordinary demand function this is a prototypical empirical example of a new modeling strategy variants of which should prove useful in many applications especially where reliance on a single valuation method is undesirable

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

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

asymmetric information about migrant earnings and remittance flows this paper examine asymmetric information about migrant earnings and its implications for remittance behavior using a sample of indian households with husbands working overseas in qatar on average wives underreport their husbands income and underreporting is more prevalent in households with higher earning migrants the discrepancy in earning reports is strongly correlated with variation in remittances greater underreporting by wives is associated with lower remittances an exchange model of remittances is developed with asymmetric information and costly state verification the optimal remittance contract prescribes a threshold for remittances that invites verification only if unmet the model s predictions closely match our empirical findings

gender differentials in farm productivity implications for household efficiency and agricultural policy abstract within many african households agricultural production is simultaneously carried out on many plots controlled by different members of the household detailed plot level agronomic data from burkina faso provides striking evidence of substantial inefficiencies in the allocation of factors of production across the plots controlled by different members of the household production function estimates imply that the value of household output could be increased by 10 15 by reallocating currently used factors of production across plots this finding contradicts standard models of agricultural households a richer model of behaviour which recognizes that the individuals who comprise a household compete as well as co operate has important implications for the structure of agricultural production and for the design of agricultural policy

recovering individual preferences for non market goods a collective travel cost model traditional recreation demand models do not make a distinction between a household and an individual as the reference decision making unit thus assuming that a family maximizes a single utility function even if the family consists of different individuals such models ignore the possibility of family members divergent preferences for non market goods this study proposes a novel approach the collective travel cost model ctcm to eliciting individual preferences for a non market good such as a recreation site by using revealed preference data this approach accounts for the intra household resource allocation and the role of each household member s preferences we show that the collective travel cost model can be applied to estimating a recreation demand model that yields individual welfare estimates appropriate for policy analysis of non market goods such as the willingness to pay to access a recreation site we find that how resources are distributed within the household reflects significant differences in welfare measures

the long term impact of international migration on economic decision making evidence from a migration lottery and lab in the field experiments this paper studies how migration from a poor to a rich country affects key economic beliefs preference parameters and transnational household decision making efficiency the setting is the migration of tongans to new zealand through a migration lottery program in a 10 year follow up survey of individuals applying for this program the study elicited risk and time preferences and pro market beliefs it also linked migrants and potential migrants to a partner household consisting of family members who would stay behind if the migrants moved survey participants played lab in the field games designed to measure the degree of intra family trust and the efficiency of intra family decision making migration provides a large and permanent positive shock to income a large change in economic institutions and a reduction in interactions with partner household members despite these changes the study finds no significant impacts of migration on risk and time preferences pro market beliefs or the decision making efficiency of transnational households this stability in the face of such a large and life changing event lends credence to economic models of migration that treat these determinants of decision making as time invariant and contrasts with recent evidence on preference changes after negative shocks

applied welfare economics with discrete choice models economists have been paying increasing attention to the study of situations in which consumers face a discrete rather than a continuous set of choices such models are potentially very important in evaluating the impact of government programs upon consumer welfare but very little has been said in general regarding the tools of applied welfare economics indiscrete choice situations this paper shows how the conventional methods of applied welfare economics can be modified to handle such cases it focuses on the computation of the excess burden of taxation and the evaluation of quality change the results are applied to stochastic utility models including the popular cases of probit and logit analysis throughout the emphasis is on providing rigorous guidelines for carrying out applied work this abstract was borrowed from another version of this item

migration and imperfect monitoring implications for intra household allocation studies of the impact of migration on sending households e g dean yang 2004 alejandra c edwards and manuelita ureta 2003 have largely neglected the fact that certain allocations can only be imperfectly monitored when household members are not coresident see ralph chami et al 2003 for an exception in this case allocations can be coordinated only to the extent that they can be verified and household decision making may not be fully cooperative the existence of such behavior among household members would suggest that expanding opportunities for migration will have different effects on expenditure patterns than simply increasing the amount of income received by the household changes in earned income and the potential to earn income will affect bargaining among spouses but noncooperative behavior will have an additional effect on the final distribution of household resources with the

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

integrating non monetary and monetary valuation methods softgis and hedonic pricing abstract in order to address the increasing need for improved linkages between different value perspectives we examine the possibility of integrating two valuation methods the non monetary softgis and monetary hedonic pricing we find them compatible and their output more comprehensive compared to traditional valuation based on one value perspective the public participatory softgis survey delivers information on the perception of urban green spaces which we use as a criterion for dividing green space categories in a hedonic pricing model we find that the perception expressed in the survey is generally consistent with the impact on property prices in the case of formal green spaces however it is inconsistent when it comes to informal ones places identified as lacking well maintained greenery exert a positive influence on property prices while positively evaluated informal green spaces had no impact at all we identify the latter as a typical trade off between different value perspectives informal green spaces are perceived differently following a monetary and a non monetary approach

the opportunity cost of travel time as a noisy wage fraction few issues are more important to welfare estimation with recreation demand models than the specification of the opportunity cost of travel time the two most common approaches to specifying this cost treat it as a fixed fraction of the recreationist s wage and either estimate the fraction done infrequently or assume it takes some value done commonly with references to results from the commute time literature used to justify the latter however these approaches lack firm conceptual rationales and the consequences of using them are not fully understood recognizing that information limitations often preclude more general approaches we use a joint recreation travel labor supply model to show that under relatively modest assumptions the opportunity cost of travel time can be expressed as a wage fraction with noise this formulation is straightforward to implement as part of random parameters based recreation demand models we then evaluate the welfare consequences of using the two approaches noted above which are special cases of the noisy wage fraction specification our results suggest that the more critical restriction to relax in opportunity cost of travel time specifications is the absence of noise rather than the specific level of the wage fraction

optimal management of a confined groundwater system abstract dynamic programming is applied to a relatively simple economic and hydrologic model of a confined aquifer system in southwest montana to determine an optimal interseasonal allocation schedule the derived decision rule demonstrates the economic advantage of maintaining a confined groundwater system while localized intraseasonal loss of the artesian pressure may occur it is important to maintain this pressure from year to year because of its role in reducing extraction costs the welfare gap as measured by differences in the net present value of economic returns to the basin under an optimal use policy versus an uncontrolled common pool situation is not trivial sensitivity analysis indicates that assumptions about uniformity of land productivity vis a vis their impact on the shape of the returns function the discount rate and the level of electric power rates are particularly critical with respect to the magnitude of the commonality problem

non cooperative institutions for sustainable common pool resource management application to groundwater as demands for limited natural resources increase developing management institutions that ensure the sustainability of such resources is essential many natural resources are common pool resources cprs managed under different non cooperative cooperative and externally imposed management frameworks while early studies of non cooperative cpr management suggest inevitable tragedy of the commons here we discuss how users can avoid tragic outcomes by changing their decision making rationales and exploitation strategies even in a non cooperative environment this paper introduces and compares various types of non cooperative institutions that are available to manage cprs these management institutions are then applied using a numerical groundwater exploitation example to determine how different planning variables are affected by the choice of management institution results indicate that cpr users can improve their gains by considering the externalities and developing long term exploitation plans as opposed to short term plans with no consideration of externalities that result in rapid exhaustion of the resource and lead to the so called tragedy of the commons

valuing the benefits of coastal water quality improvements using contingent and real behaviour recent moves in the european union have beenmade towards a toughening of legislation onbathing water quality this has focussedpolicy makers thoughts on the welfare benefitsresulting from such improvements especiallygiven their cost our paper uses a combinedstated and revealed preference approach tovalue coastal water quality improvements focussing on an area of scotland which hasconsistently failed to meet standards under thebathing waters directive we combine data onreal behaviour with data on contingentbehaviour using a random effects negativebinomial panel model this allows us to predictboth the change in participation trips shouldwater quality be improved and the welfareincrease per trip our model includes allowancefor the existence of substitute sites and forchanges in recreational behaviour during abeach visit

testing between competing models of sharecropping the marshallian approach assumes a prohibitively high cost of monitoring the sharecropper s activities while the monitoring approach argues that landlords stipulate and effectively monitor sharecroppers activities i present new evidence using detailed data collected from eight indian villages most tenants own some land of their own this provides a controlled environment in studying the impact of contractual arrangements the differences in input and output intensities on owned minus sharecropped land of the same household are found to be sizable and significant suggesting a rejection of the monitoring approach and supporting the notion of the marshallian productive inefficiency of sharecropping

augmenting travel cost models with contingent behavior data this paper proposes contingent behavior survey questions as a valuable supplement to observed data in travel cost models of non market demand for recreational resources a set of observed and contingent behavior results for each survey respondent allows the researcher to control for individual heterogeneity by taking advantage of panel data methods when exploring the nature of respondent demands the contingent scenarios also provide opportunities to a test for differences between observed and contingent preferences and or b assess likely demands under conditionsbeyond the domain of observed variation in costs or resource attributes most importantly contingent scenarios allow the researcher to imposeexogenously varying travel costs exogenous imposition of travel costs together with panel methods reduces the omitted variables bias that plagues observed data travel cost models of recreational demand using a convenience sample of data for illustrative purposes we show how to estimate the demand for recreational angling by combining observed and contingent behavior data we begin with simple naive pooled poisson models and progress to more theoretically appropriate fixed effects panel poisson specifications

noncooperative bargaining models of marriage in this paper we discuss some simple noncooperative models of distribution within marriage in which the equilibria are not necessarily pareto optimal in which history and culture can affect which equilibrium is realized and in which distribution may depend on whether resources are controlled by the husband or by the wife recent moves away from single decision maker models of the family have permitted economists to address distribution within marriage and cooperative bargaining models have played the central role in these moves the next step is to permit strategic interaction between family members by modeling distribution within marriage as a noncooperative game noncooperative game theory allows great flexibility in specifying the rules of the game and unlike cooperative game theory imposes few a priori restrictions on the nature of equilibrium outcomes in particular noncooperative models neither assume nor imply that all equilibria are pareto optimal

inefficiency of male and female labor supply in agricultural households evidence from uganda this article analyzes the efficiency of the intra household allocation of female and male labor inputs in agricultural production in a collective household model spouses optimal on farm labor supply is such that the marginal rate of technical substitution between male and female labor is equated over different crops using the uganda national household survey 2005 06 we test whether this condition holds by estimating production functions and controlling for endogeneity using a method proposed by gandhi navarro and rivers 2009 we find that women are less productive than men that there is more female labor input on low productivity parcels and that men are relatively more productive on female controlled plots compared with male controlled plots total farm output could be higher and pareto improvements could be possible if male labor was reallocated to female controlled plots and or female labor was reallocated to male controlled plots

determinants and effects of income diversification amongst farm households in burkina faso using four years of household data from three agroecological zones in burkina faso sahelian sudanian and guinean the article examines the determinants and effects of household income diversification harvest shortfalls and terms of trade are found to drive diversification but land constraints do not income diversification is associated with higher incomes and food consumption and more stable income and consumption over years

intrahousehold allocation and bargaining power evidence from chile abstract until 1999 children born out of wedlock in chile had fewer child support rights than those born to married couples i interpret a change in this law as an increase in the household bargaining power of women in cohabiting relationships using a panel of cross sectional data i find a decrease of 1 8 percentage points in the probability of working among men and an increase of 1 2 percentage points in school attendance of children under 19 these results provide evidence that contradicts the predictions of the unitary household model as well as the nash bargaining model the labor market outcomes support a model in which a reduction in men s relative bargaining power is understood as a tax on their wages

baby boomer retirement security the roles of planning financial literacy and housing wealth abstract we compare wealth holdings across two cohorts of the health and retirement study the early baby boomers in 2004 and individuals in the same age group in 1992 levels and patterns of total net worth have changed relatively little over time though boomers rely more on housing equity than their predecessors most important planners in both cohorts arrive close to retirement with much higher wealth levels and display higher financial literacy than non planners instrumental variables estimates show that planning behavior can explain the differences in savings and why some people arrive close to retirement with very little or no wealth

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

collective labor supply and welfare the paper develops a general collective model of household labor supply in which agents are characterized by their own possibly altruistic preferences and household decisions are only assumed to be pareto efficient an alternative interpretation is that there are two stages in the internal decision process agents first share nonlabor income according to some given sharing rule then each one optimally chooses his or her own labor supply and consumption this setting is shown to generate testable restrictions on labor supplies moreover the observation of labor supply behavior is sufficient for recovering individual preferences and the sharing rule up to a constant finally the traditional tools of welfare analysis can be adapted to the new setting

directing remittances to education with soft and hard commitments evidence from a lab in the field experiment and new product take up among filipino migrants in rome this paper tests how migrants willingness to remit changes when given the ability to direct remittances to educational purposes using different forms of commitment variants of a dictator game in a lab in the field experiment with filipino migrants in rome are used to examine remitting behavior under varying degrees of commitment these range from the soft commitment of simply labeling remittances as being for education to the hard commitment of having funds directly paid to a school and the student s educational performance monitored the analysis finds that the introduction of simple labeling for education raises remittances by more than 15 percent adding the ability to directly send this funding to the school adds only a further 2 2 percent the information asymmetry between migrants and their most closely connected household is randomly varied but no significant change is found in the remittance response to these forms of commitment as information varies behavior in these games is shown to be predictive of take up of a new financial product called edupay designed to allow migrants to pay remittances directly to schools in the philippines this take up seems largely driven by a response to the ability to label remittances for education rather than to the hard commitment feature of directly paying schools

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

current issues in the economics of groundwater resource management the issue of groundwater management remains a practical concern in many regions throughout the world while water managers continue to grapple with the question of how to manage this resource in this article we attempt to bring the most advanced and appropriate tools to bear on the issue of resource allocation involving groundwater our objective is to demonstrate the state of the art in the literature on ways to think about this complex resource and to deal with the important economic issues emanating from its complexity we present the conceptual framework within which economists examine the elements interacting in the management of groundwater resources indicate why the role of the market is limited with respect to the price of this very complex resource and point to the mechanisms that can pull competitive groundwater price and quality graded quantity of groundwater in line with their equilibrium levels in particular we critically review economic models of groundwater use examine the potential for groundwater management discuss the difficulties encountered in the estimation of the relevant control variables of such models and identify the advantages and limitations of the instruments devised for the efficient use allocation of this resource finally we argue that devised regulatory schemes usually ignore the information and knowledge needed for their implementation and we suggest a core of conditions necessary for successful groundwater management reforms

gender agricultural production and the theory of the household virtually all models of the household assume that the allocation of resources is pareto efficient within many african households agricultural production occurs on many plots controlled by different members of the household pareto efficiency implies that factors should be allocated efficiently across these plots i find in contrast that plots controlled by women are farmed much less intensively than similar plots within the household controlled by men the estimates imply that about 6 percent of output is lost because of inefficient factor allocation within the household the paper suggests a new approach to modeling intrahousehold allocation consistent with the empirical results

efficient intra household allocations a general characterization and empirical tests the neoclassical theory of demand applies to individuals yet in empirical work it is usually taken as valid for households with many members this paper explores what the theory of individuals implies for households that have more than one member we make minimal assumptions about how the individual members of the household resolve conflicts all we assume is that however decisions are made outcomes are efficient we refer to this as the collective setting we show that in the collective setting household demands must satisfy a symmetry and rank condition on the slutsky matrix we also present some further results on the effects on demands of variables that do not modify preferences but that do affect how decisions are made we apply our theory to a series of surveys of household expenditures from canada the tests of the usual symmetry conditions are rejected for two person households but not for one person households we also show that income pooling is rejected for two person households we then test for our collective setting conditions on the couples data none of the collective setting restrictions are rejected we conclude that the collective setting is a plausible and tractable next step to take in the analysis of household behavior

the effects of well management and the nature of the aquifer on groundwater resources we compare groundwater use under collective well management in china where village leaders allocate water among households and under private well management where farmers either pump from their own wells or buy water from wells owned by other farmers villages are divided into connected or isolated groups depending on whether there are lateral groundwater flows between aquifers underlying a village and neighboring ones in rural china households under collective well management use less water even under collective management households located in connected villages use more water indicating that the connectedness of the aquifers may undermine leaders incentives to conserve water

competitive versus efficient extraction of a common property resource the groundwater case abstract in this paper socially optimal and private extraction of a common property aquifer are compared open loop equilibrium and feedback equilibrium in linear strategies have been computed to characterize private extraction the use of these two equilibrium concepts allows us to distinguish between cost and strategic externalities as long as the open loop solution captures only the cost externality and the feedback solution captures both the results show that strategic behaviour increases the overexploitation of the aquifer compared to the open loop solution however if the groundwater storage capacity is large the difference between the socially optimal and private extraction the latter characterized by a feedback equilibrium is negligible

valuing water quality as a function of water quality measures employing a unique and rich data set of water quality attributes in conjunction with detailed household characteristics and trip information we develop a mixed logit model of recreational lake usage and undertake thorough model specification and fitting procedures to identify the best set of explanatory variables and their functional form for the estimated model our empirical analysis shows that individuals are responsive to the full set of water quality measures used by biologists to identify the impaired status of lakes thus changes in these quality measures are not simply a scientific exercise but they also translate into changes in the recreational usage patterns and well being of individual households willingness to pay wtp estimates are reported based on improvements in these physical measures

short run constraints and the increasing marginal value of time in recreation leisure activities such as local recreation trips usually take place in discrete blocks of time that are surrounded by time devoted to other commitments it can be costly to transfer time between blocks to allow for longer outings these observations affect the value of time within those blocks and suggest that traditional methods for valuing time using labor markets miss important considerations this paper presents a new model for time valuation that uses non employment time commitments to infer the shadow value of time spent in recreation a unique survey that elicited revealed and stated preference data on household time allocation is used to implement the model the results support the conclusion that there is an increasing marginal value of time for recreation as the trip length increases

spousal control and intra household decision making an experimental study in the philippines i elicit causal effects of spousal observability and communication on financial choices of married individuals in the philippines when choices are private men put money into their personal accounts when choices are observable men commit money to consumption for their own benefit when required to communicate men put money into their wives account these strong treatment effects on men but not women appear related more to control than to gender men whose wives control household savings respond more strongly to the treat ment and women whose husbands control savings exhibit the same response changes in information and communication interact with underlying control to produce mutable gender specific outcomes

migrant remittances and information flows evidence from a field experiment do information flows matter for remittance behavior we design and implement a randomized control trial to quantitatively assess the role of communication between migrants and their international n

altruism in networks we provide the first analysis of altruism in networks agents are embedded in a fixed network and care about the well being of their network neighbors depending on incomes they may provide financial support to their poorer friends we study the nash equilibria of the resulting game of transfers we show that equilibria maximize a concave potential function we establish existence uniqueness of equilibrium consumption and generic uniqueness of equilibrium transfers we characterize the geometry of the network of transfers and highlight the key role played by transfer intermediaries we then study comparative statics a positive income shock to an individual benefits all for small changes in incomes agents in a component of the network of transfers act as if they were organized in an income pooling community a decrease in income inequality or expansion of the altruism network may increase consumption inequality

remittances and the use of formal and informal financial services summary while recent literature has pointed to a positive effect of migrants remittances on the financial development of receiving countries findings with respect to access to and the use of loans have been ambiguous this paper investigates the effect of remittances on the use of formal and informal financial services using mexican household data and finds positive and statistically significant effects of remittances on the ownership of savings accounts the existence of debts and on recent borrowing the fact that the effect of remittances on borrowing is driven by informal finance rather than by traditional bank loans points to deficiencies of the formal financial sector in addressing the financial needs of remittance receiving households we address methodological concerns of selection bias and reverse causality through household fixed effects and an instrumental strategy that exploits distance to train lines and labor market conditions in the us as exogenous determinants of remittances

alimony rights and intrahousehold allocation of resources evidence from brazil can family policy affect well being of individuals without altering the resources available to their families this article examines the extension of alimony rights and obligations to cohabiting couples in brazil for women in intact relationships alimony rights upon dissolution should improve outside options strengthening their negotiating positions and increasing their influence over intrahousehold allocation of resources robust econometric evidence indicates that more decision power in the hands of women impacts hours worked by female adults and investments in the education of children this suggests that family policy and models of family decision making should take intrahousehold heterogeneity of preferences into account

don t tell on me experimental evidence of asymmetric information in transnational households although most theoretical models of household decision making assume perfect information empirical studies suggest that information asymmetries can have large impacts on resource allocation i demonstrate the importance of these asymmetries in transnational households where physical distance between family members can make information barriers especially acute i implement an experiment among migrants in washington dc and their families in el salvador that examines how information asymmetries can have strategic and inadvertent impacts on remittance decisions migrants make an incentivized decision over how much of a cash windfall to remit and recipients decide how they will spend a remittance migrants strategically send home less when their choice is not revealed to recipients recipients make spending choices closer to migrants preferences when the migrants preferences are shared regardless of whether or not the spending choices are revealed to the migrants suggesting that recipients choices are inadvertently affected by imperfect information

shadow wages and peasant family labour supply an econometric application to the peruvian sierra a striking feature of developing economies is the large proportion of the work force that is self employed lack of widespread labor market participation in the agricultural sector can pose a major obstacle to the empirical implementation of economic models of the peasant household whether because wage data are simply not available or because the assumptions required to make use of wage data stretch the bounds of credulity this paper develops a methodology for estimating a structural labor supply model for primarily self employed peasant households which holds under a general agricultural technology and set of labor market conditions the unique feature of the approach is that the opportunity cost of time or shadow wage of household workers is explicitly estimated from an agricultural production function and is subsequently used to identify a set of structural labor supply parameters recent household survey data from rural peru is employed to estimate and perform various diagnostic tests on the model the empirical findings lend support to the hypothesis that peasant households allocate their members time as if to maximize a family utility function and moreover demonstrate the tractability of the shadow wage methodology and its usefulness in estimating more elaborate time allocation models

directed giving evidence from an inter household transfer experiment abstract we investigate the determinants of giving in a lab in the field experiment with large stakes study participants in urban mozambique play dictator games where their counterpart is the closest person to them outside their household when given the option dictators do a large fraction of giving in kind in the form of goods rather than cash in addition they share more in total when they have the option of giving in kind compared to giving that can only be in cash qualitative post experiment responses suggest that this effect is driven by a desire to control how recipients use gifted resources standard economic determinants such as the rate of return to giving and the size of the endowment also affect giving but the effects of even large changes in these determinants are significantly smaller than the effect of the in kind option our results support theories of giving where the utility of givers depends on the composition not just the level of gift recipient expenditures and givers thus seek control over transferred resources

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

a difficulty with the travel cost method instead of observable prices of recreational visits travel cost method tcm re searchers are obliged to substitute researcher assigned visitation cost estimates i argue that visitation costs are inherently subjective but are ordinally measurable so long as the cost in creases with distance travelled it follows that traditional tcm yields only ordinally measur able welfare estimates the household produc tion function formulation of tcm resolves this problem only by imposing severe and un testable analytical restrictions tcm cannot serve as a stand alone technique for estimating recreation benefits rather it must be calibrated using information generated with fundamentally different methods jel q26

strategic behavior and efficiency in the common property extraction of groundwater groundwater has always been regarded as a common property resource where entry is restricted by land ownership and private exploitation is inefficient in 1980 gisser and sanchez presented a first estimation of this inefficiency cornparing socially optimal exploitation with private competitive exploitation using a model with linear water demand average extraction cost independent of the rate of extraction and linearly decreasing with respect to the water table level they characterized the private exploitation of the aquifer assuming that farmers are myopic and choose their rate of extraction to maximize their current profits whereas optimal exploitation is obtained by maximizing the present value of the stream of aggregate profits their results show that if the storage capacity of the aquifer is relatively large the difference between the two systems is so small that it can be ignored for practical consideration this result has been called the gisser sanchez rule by nieswiadomy 1985 and it has and important policy implication regulation of the resource does not seem justified since the profits it brings are not very high 1

the value of purchase history data in target marketing an important aspect of marketing practice is the targeting of consumer segments for differential promotional activity the premise of this activity is that there exist distinct segments of homogeneous consumers who can be identified by readily available demographic information the increased availability of individual consumer panel data open the possibility of direct targeting of individual households the goal of this paper is to assess the information content of various information sets available for direct marketing purposes information on the consumer is obtained from the current and past purchase history as well as demographic characteristics we consider the situation in which the marketer may have access to a reasonably long purchase history which includes both the products purchased and information on the causal environment short of this complete purchase history we also consider more limited information sets which consist of only the current purchase occasion or only information on past product choice without causal variables proper evaluation of this information requires a flexible model of heterogeneity which can accommodate observable and unobservable heterogeneity as well as produce household level inferences for targeting purposes we develop new econometric methods to implement a random coefficient choice model in which the heterogeneity distribution is related to observable demographics we couple this approach to modeling heterogeneity with a target couponing problem in which coupons are customized to specific households on the basis of various information sets the couponing problem allows us to place a monetary value on the information sets our results indicate there exists a tremendous potential for improving the profitability of direct marketing efforts by more fully utilizing household purchase histories even rather short purchase histories can produce a net gain in revenue from target couponing which is 2 5 times the gain from blanket couponing the most popular current electronic couponing trigger strategy uses only one observation to customize the delivery of coupons surprisingly even the information contained in observing one purchase occasion boasts net couponing revenue by 50 more than that which would be gained by the blanket strategy this result coupled with increased competitive pressures will force targeted marketing strategies to become much more prevalent in the future than they are today

who you train matters identifying complementary effects of financial education on migrant households there has long been a concern among policymakers that too much of remittances are consumed and too little saved limiting the development impact of migration financial literacy programs have become an increasingly popular way to try and address this issue but to date there is no evidence that they are effective in inducing savings among remittance receiving households nor is it clear whether such programs are best targeted at the migrant the remittance receiver or both the authors conducted a randomized experiment in indonesia which allocated migrants and their families to a control group a migrant only training group a family member only training group and a training group in which both the migrant and a family member were trained three rounds of follow up surveys are then used to measure impacts on the financial knowledge behaviors and remittance and savings outcomes of the remaining household they find that training both the migrant and the family member together has large and significant impacts on knowledge behaviors and savings training the family member alone has some positive but smaller effects whilst training only the migrant leads to no impacts on the remaining family members the results show that financial education can have large effects when provided at a teachable moment but that this impact varies greatly with who receives training

tying odysseus to the mast evidence from a commitment savings product in the philippines we designed a commitment savings product for a philippine bank and implemented it using a randomized control methodology the savings product was intended for individuals who want to commit now to restrict access to their savings and who were sophisticated enough to engage in such a mechanism we conducted a baseline survey on 1777 existing or former clients of a bank one month later we offered the commitment product to a randomly chosen subset of 710 clients 202 28 4 percent accepted the offer and opened the account in the baseline survey we asked hypothetical time discounting questions women who exhibited a lower discount rate for future relative to current trade offs and hence potentially have a preference for commitment were indeed significantly more likely to open the commitment savings account after twelve months average savings balances increased by 81 percentage points for those clients assigned to the treatment group relative to those assigned to the control group we conclude that the savings response represents a lasting change in savings and not merely a short term response to a new product

a theoretical foundation for count data models the paper develops a theoretical foundation for using count data models in travel cost analysis two micro models are developed a restricted choice model and a repeated discrete choice model we show that both models lead to identical welfare measures

the economics of polygyny in sub saharan africa female productivity and the demand for wives in cote d ivoire polygyny is still practiced throughout much of sub saharan africa with important social consequences this paper makes the first attempt to link african polygyny directly to the productivity of women in agriculture using micro data i develop a structural model of the demand for wives that disentangles wealth and substitution effects using a large household survey from cote d ivoire i find that marked geographic diversity in cropping patterns leads to regional variation in female labor productivity i also find that conditional on wealth men do have more wives when women are more productive that is cheaper this substitution effect may explain why polygyny declined in rural areas of cote d ivoire during agricultural development

separate spheres bargaining and the marriage market this paper introduces the separate spheres bargaining model a new model of distribution within marriage it differs from divorce threat bargaining models e g manser brown mcelroy horney in that the threat point is not divorce but a noncooperative equilibrium within marriage this noncooperative equilibrium reflects traditional gender roles the predictions of our model thus differ from those of divorce threat bargaining models in the separate spheres model cash transfer payments to the mother and payments to the father can but need not imply different equilibrium distributions in existing marriages in the long run the distributional effects of transfer policies may be substantially altered by changes in the marriage market equilibrium

on the commodity value of travel time in recreational activities the allocation of individual time can have a commodity value if the use of time is enjoyable this paper investigates the commodity value of travel time in recreational activities the study focuses on recreational boating in east texas after specifying a model of multisite recreational demand for boating the commodity value of travel time to each site is estimated implications of the results for the analysis of outdoor recreation are discussed

income and outcomes a structural model of intrahousehold allocation there is evidence from several sources that one cannot treat many person households as a single decision maker if this is the case then factors such as the relative incomes of the household members may affect the final allocation decisions made by the household we develop a method of identifying how incomes affect outcomes given conventional family expenditure data the basic assumption we make is that household decision processes lead to efficient outcomes we apply our method to a sample of canadian couples with no children we find that the final allocations of expenditures on each partner depend significantly on their relative incomes and ages and on the level of lifetime wealth

pareto improving water management over space and time the honolulu case we model welfare gains from efficient allocation of groundwater over space and time relative to the status quo policy of financial cost recovery in order to promote political feasibility an intertemporal compensation plan is devised that renders the reform pareto improving gainers from the reform finance the compensation in proportion to their benefits through a block pricing scheme for the honolulu case only 7 of the 441 million in gains to winners is needed to compensate losers from the reform future winners from the reform also repay the deficit created by the compensation package much as state and local governments finance capital improvements copyright 2009 oxford university press

modeling recreation demand in the presence of unobservable travel costs toward a travel price model an important issue in the application of travel cost models is the construction of a travel cost variable this paper develops an econometric approach that views travel costs as an unobserved latent variable the latent variable approach utilizes indicators to capture the role of individual travel costs in recreational demand models the latent variables approach has at least two advantages over conventional approaches one the indicators can include both traditional components such as time and distance and non traditional components such as the scenic beauty second the estimation procedure results in each indicator being valued in dollar terms

value of recreational fishing in the brazilian pantanal a travel cost analysis using count data models abstract recreational fishing value of the brazilian pantanal is measured using travel cost method tcm we compare non linear poisson and negative binomial count data models to estimate recreational fishing trip demands the count data and truncated models are used primarily to account for non negative integer and truncation properties of recreational fishing trips as suggested by the recreation valuation literature the results reveal that non linear and truncated count data models perform relatively well in our study the economic values of recreational fishing in terms of consumer surplus cs are derived using non linear and truncated models we estimate the cs values from 540 54 to 869 57 per trip resulting in the total social welfare estimate range from 35 to 56 million the study demonstrates a relatively high value of recreational fishing in the pantanal in comparison to similar studies conducted in other parts of the world the findings of this study would be important for resource management decisions in the pantanal and could serve as a reference in valuing similar resources in other ecosystems around the world

can unobserved land quality explain the inverse productivity relationship abstract an inverse relationship between both farm productivity and labor intensity and farm size is a common empirical finding in developing country agriculture the traditional explanation has been imperfect labor markets recently it has been suggested instead that the inverse relationship is a statistical artifact resulting from omitted land quality using a farm level data set from java i investigate whether omitted variable bias can explain the inverse relationship i show that the inverse relationship and accompanying wage responses are inconsistent with a model of neoclassical farm behavior that ignores omitted variable bias instrumental variables techniques yield parameter estimates in which the inverse relationship is eliminated and the estimated wage elasticities are more in line with economic theory further econometric investigation hints that a model of omitted land quality may be a possible source of the inverse relationship these results emphasize the importance of considering the sources of cross sectional variation in estimating microeconomic relationships
