an economic theory of self control the concept of self control is incorporated in a theory of individual intertemporal choice by modeling the individual as an organization the individual at a point in time is assumed to be both a farsighted planner and a myopic doer the resulting conflict is seen to be fundamentally similar to the agency conflict between the owners and managers of a firm both individuals and firms use the same techniques to mitigate the problems which the conflicts create this paper stresses the implications of this agency model and discusses as applications the effect of pensions on saving saving and the timing of income flows and individual discount rates

propensity to consume farm family disposable income from separate sources farm family disposable income is generated from farm operations off farm sources and government payments if these three income components are fungible a dollar from one source is a perfect substitute for a dollar from another source then the propensities to consume each should be the same this study examines the farm family propensity to consume from separate income sources results indicate that the propensity to consume off farm income and government payments is higher than the propensity to consume farm income

can self control explain avoiding free money evidence from interest free student loans abstract this paper uses insights from behavioral economics to explain a particularly surprising borrowing phenomenon one in six undergraduate students offered interest free loans turns them down models of impulse control predict that students may optimally reject subsidized loans to avoid excessive consumption during school using the national postsecondary student aid study we investigate students take up decisions and identify a group of students for whom the loans create an especially tempting liquidity increase students who would receive the loan in cash are significantly more likely to turn it down suggesting that consumers choose to limit their liquidity in economically meaningful situations

consumer response to the reagan tax cuts abstract this paper uses micro data from the consumer expenditure survey to estimate the response of household consumption to the second and third phases of the reagan tax cuts since these phases were pre announced they allow for an unusually clean test of the canonical life cycle permanent income model consumption is found to be excessively sensitive to the tax cuts counter to the model liquidity constraints and other standard explanations do not appear to explain this excess sensitivity the consumption response is larger than previously estimated for tax refunds and more concentrated in nondurables these differences have important implications for the structure of tax changes in particular for choosing between varying withholding rates versus varying lumpy final tax payments and refunds

why have private savings rates in the united states and canada diverged abstract one of the central questions in macroeconomics for many years has been whether government policy can affect private saving rates and if so to what extent and through what channels the question has remained controversial because as with other macroeconomic questions experiments to check divergent hypotheses cannot be deliberately performed so economists must rely upon the often dubious evidence from the limited experiments with which nature and history have endowed us this paper discusses the results of an exceptionally good natural experiment that has been provided by canada and the u s over the past thirty five years after moving in tandem for almost twenty five years american and canadian private saving rates have diverged dramatically over the last decade the primary conclusion emerging from our analysis of this phenomenon is that tax policies can have a potent impact on private savings behavior differences in tax structures and in the interactions of taxation and inflation appear to be important factors explaining the divergent behavior of the american and canadian private savings rates recognizing the importance of asset revaluations caused partially but not entirely by tax effects also helps to explain the different behavior of u s and canadian savings there may also be a relationship between government deficits and the private savings differential

the hyperbolic consumption model calibration simulation and empirical evaluation ur preferences for the long run tend to conflict with our short run behavior when planning for the long run we intend to meet our deadlines exercise regularly and eat healthfully but in the short run we have little interest in revising manuscripts jogging on the stairmaster and skipping the chocolate souffleala mode delay of gratification is a nice long term goal but instant gratification is disconcertingly tempting this gap between long run intentions and short run actions is apparent across a wide range of behaviors including saving choices a 1997 survey found that 76 percent of respondents believe they should be saving more for retirement looking only at respondents who believed they were at an age where you should be seriously saving already the survey found that 55 percent reported being behind in their savings and only 6 percent reported being ahead farkas and johnson 1997 the report on the survey concluded t he gaps between people s atti tudes intentions and behavior are troubling and threaten increased insecurity and dissatisfaction for people when they retire americans are simply not doing what logic and their own reasoning suggests they should be doing a 1993 luntz webber merrill lynch survey found similar answers when baby boomers were asked what percentage of your annual household income do you think you should save for retirement and what percentage of your annual

search and collusion in electronic markets we examine the impact of reduced search costs on prices of commodity products in electronic marketplaces conventionally reduced consumer search costs may be expected to engender stronger price competition between firms resulting in lower prices and improved consumer welfare this notion was formalized in stahl 1989 oligopolistic pricing with sequential consumer search american economic review vol 79 no 4 pp 700 712 in a model of static firm competition in this paper we show that these standard welfare conclusions may be neutralized or reversed in a dynamic environment we focus on self enforcing collusion by firms and characterize the conditions under which collusive equilibria exist we show that less costly consumer search can facilitate firms abilities to collude resulting in higher prices and reduced consumer welfare even with imperfect or no monitoring by sellers of each other s prices if the same technology that eases consumer search also allows firms to monitor each other s prices more easily then firms can more easily detect cheating on a collusive price arrangement allowing an even greater scope for collusion this raises antitrust concerns with respect to the electronic marketplace and suggests that at least some of the anticipated competitive gains from electronic market systems may be difficult to realize

pension plan characteristics and framing effects in employee savings behavior abstract defined contribution pensions in many postsecondary institutions are funded by a combination of an employer premium and a mandatory employee premium individuals can also contribute to a supplemental savings account holding constant total compensation standard reasoning suggests that supplemental savings should depend negatively on the sum of the employer and employee pension contributions contrarily we find that the supplementary savings of professors are significantly more sensitive to employee contributions than to employer contributions this asymmetry is consistent with different marginal propensities to save out of the salary and pension components of compensation nevertheless impacts on lifetime utility are relatively modest

consumer response to tax rebates many households received income tax rebates in 2001 of 300 or 600 these rebates represented advance payments of the tax cut from the new 10 percent tax bracket based on a survey of a representative sample of households this paper finds that only 22 percent of households receiving the rebate would spent it instead they would either save it or use it to pay off debt this very low rate of spending represents a striking break with past behavior which would have suggested a much higher rate of spending the low spending rate implies that the tax rebate provided a very limited stimulus to aggregate demand this abstract was borrowed from another version of this item

static modeling of dynamic recreation behavior implications for prediction and welfare estimation abstract this paper examines the consequences of using a static model of recreation trip taking behavior when the underlying decision problem is dynamic specifically we examine the implications for trip forecasting and welfare estimation using a panel dataset of lake michigan salmon anglers for the 1996 and 1997 fishing seasons we derive and estimate both a structural dynamic model using bellman s equation and a reduced form static model with trip probability expressions mimicking those of the dynamic model we illustrate an inherent identification problem in the reduced form model that creates biased welfare estimates and we discuss the general implications of this for the interpretation of preference parameters in static models we then use both models to simulate trip taking behavior and show that although their in sample trip forecasts are similar their welfare estimates and out of sample forecasts are quite different

do free goods stick to poor households experimental evidence on insecticide treated bednets summary if the market allocates goods to those willing and able to pay the most for them efforts to target durable health goods such as insecticide treated bednets itns to poor populations may prove ineffective with the poor reselling donated goods to the non poor who value them more highly however low market demand may be due to liquidity constraints rather than low valuation of nets the endowment effect also militates against the resale of in kind transfers we quantify these two effects through a field experiment in uganda our results indicate that very few nets will be resold by recipient households

opportunity costs in buying and short selling do they really matter abstract the experimental results of the paper reveal that people do not take into consideration opportunity costs or opportunity profits when buying and short selling lottery tickets these results are inconsistent with basic economic and finance theories

microenterprise growth and the flypaper effect evidence from a randomized experiment in ghana standard models of investment predict that credit constrained firms should grow rapidly when given additional capital and that how this capital is provided should not affect decisions to invest in the business or consume the capital we randomly gave cash and in kind grants to male and female owned microenterprises in urban ghana for women running subsistence enterprises we find no gain in profits from either treatment for women with larger businesses we strongly reject equality of the cash and in kind grants only in kind grants cause growth in profits suggesting a flypaper effect whereby capital coming directly into the business sticks there but cash does not the results for men also suggest a lower impact of cash but differences between cash and in kind grants are less robust there is suggestive evidence that the difference in the effects of cash and in kind grants is associated more with lack of self control than with external pressure

the ricardian approach to budget deficits persistent budget deficits have increased economists interest in theories and evidence about fiscal policy this paper develops the ricardian approach and contrasts it with standard models the discussion considers from major theoretical objections to ricardian equivalence finite lifetimes imperfect capital markets uncertainty about future taxes and incomes and the distorting effects of taxation the paper then considers empirical evidence on interest rates consumption and saving and current account deficits the conclusion is that the ricardian approach is a useful first order approximation and that this approach will probably become the benchmark model for assessing fiscal policy this abstract was borrowed from another version of this item

estimating the effect of unearned income on labor supply earnings savings and consumption evidence from a survey of lottery players this paper provides empirical evidence about the effect of unearned income on earnings consumption and savings using an original survey of people playing the lottery in massachusetts in the mid 1980 s the effects of the magnitude of lottery prizes on economic behavior are analyzed the critical assumption is that among lottery winners the magnitude of the prize is randomly assigned it is found that unearned income reduces labor earnings with a marginal propensity to consume leisure of approximately 11 percent with larger effects for individuals between 55 and 65 years old after receiving about half their prize individuals saved about 16 percent

saving more in groups field experimental evidence from chile abstract we test the impact of a peer group program on savings in a sample of microcredit clients we conduct two randomized trials among these 2687 microcredit clients the first finds that a savings group treatment which combines public goal setting monitoring in the group and non financial rewards increases savings in a new savings account significantly the number of deposits grows 3 7 fold and the average balance almost doubles in contrast a more classical measure a substantially increased interest rate has no effect for most participants and raises the savings balance only for the very top of the distribution a second experiment conducted a year later tests an alternative delivery mechanism and shows that effects of similar size can be achieved through feedback text messages without meetings rewards or peer pressure given that participants are borrowing at 90 apr we discuss how and when saving more could be harmful or beneficial

wage subsidies and fair wages abstract wage subsidies can be provided directly to the worker or indirectly by subsidizing the employer with reduced cost of labor employers offer higher wages the standard literature stipulates that this statutory incidence bears no implications for the economic incidence we propose and test a mechanism by which indirect subsidies lead to higher social welfare studies show that workers reciprocate higher wages with higher effort indirect subsidies are shifted to the workers as higher wages leading workers to reciprocate with higher effort and productivity a controlled laboratory experiment supports our behavioral hypotheses and confirms the behavioral and welfare implications

mental accounting and decision making the relationship between relative and absolute savings abstract the formation of mental accounts by individuals has been hypothesised to explain an apparent departure from rationality in certain decision making scenarios in particular the potential monetary saving on an item is viewed topically relative to the original expected cost of that item rather than relative to the original expected cost of all items purchased on the same shopping trip in other words in a number of contexts the relative saving to be made has been found to be more important than the absolute saving this paper extends previous experimental work by describing a new experiment that seeks to discover whether this mental accounting characteristic applies more widely we find that the effect is not detected as the level of absolute saving to be gained increases suggesting that topical accounts are less important in such contexts

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

the effect of liquidity constraints on consumption a cross sectional analysis this paper examines the effect of liquidity constraints on consumption expenditures using a single year cross section data set a reduced form equation for consumption is estimated on high saving households by the tobit procedure to account for the selectivity bias since high saving households are not likely to be liquidity constrained the estimated equation is an appropriate description of how desired consumption that would be forthcoming without liquidity constraints is related to the variables available in the cross section data when the reduced form equation is used to predict desired consumption the gap between desired consumption and measured consumption is most evident for young households

the citizen versus consumer distinction an exploration of individuals preferences in contingent valuation studies abstract contingent valuation has been used extensively in estimating the value of environmental goods one criticism of this approach however is that respondents in referendum style contingent valuation surveys may express citizen assessments that take into account benefits to others rather than benefits that accrue purely to the respondent themselves within this context the aim of this paper is to examine to what extent individuals express different preferences when adopting a personal or a social citizen perspective while this paper provides some support for the hypothesis that individuals express different preferences when adopting collective as opposed to personal choices reported willingness to pay wtp was found to be insensitive to whether or not the respondents were asked the wtp question from a personal or social perspective

the behavioral life cycle hypothesis self control mental accounting and framing are incorporated in a behavioral enrichment of the life cycle theory of saving called the behavioral life cycle blc hypothesis the key assumption of the blc theory is that households treat components of their wealth as nonfungible even in the absence of credit rationing specifically wealth is assumed to be divided into three mental accounts current income current assets and future income the temptation to spend is assumed to be greatest for current income and least for future income considerable empirical support for the blc theory is presented primarily drawn from published econometric studies

the sunk cost fallacy in penny auctions this article theoretically and empirically analyses behaviour in penny auctions a relatively new auction mechanism as in the us dollars or war of attrition players in penny auctions commit higher non refundable costs as the auction continues and only win if all other players stop bidding i first show that in any equilibria that does not end immediately players bid probabilistically such that the expected profit from every bid is zero then using two large data sets covering 166 000 auctions i calculate that average profit margins actually exceed 50 to explain this deviation i incorporate a sunk cost fallacy into the theoretical model to generate a set of predictions about hazard rates and player behaviour which i confirm empirically while players do slowly learn to correct this bias and there are few obvious barriers to competition activity in the market is rising and concentration remains relatively high

social security benefits consumption expenditure and the life cycle hypothesis this paper examines the impact of changes in social security benefits on aggregate consumption expenditure under the null hypothesis there should be no contemporaneous effect at the monthly frequency because increases in benefits have always been announced at least 6 weeks prior to payment the paper develops overwhelming evidence contrary to the null that benefits have affected aggregate spending the results have strong implications for several important issues including ricardian equivalence government policy irrelevance and the excess sensitivity of consumption to changes in income

economic valuation of the environment how citizens make sense of contingent valuation questions this study adopts a qualitative approach in order to investigate how people make sense of contingent valuation cv questions of a global environmental amenity the objective is not only to capture people s motivations and considerations of willingness to pay wtp but also to determine if they adequately comprehend an economic valuation of such public goods the findings indicate that a large proportion of respondents do not interpret the valuation task as intended however this lack of understanding is not always expressed unless probed in relation to the elicitation question and some people have the tendency to provide monetary estimates anyway whatever meaning they attach to these

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

estimating the benefit incidence of an antipoverty program by propensity score matching this brief summarizes the results of a gender impact evaluation study entitled estimating the benefit incidence of an antipoverty program by propensity score matching conducted between 1997 and 1998 in argentina the study observed that the average direct gain to the participant is found to be about half the gross wage over half of the beneficiaries are in the poorest decile nationally and 80 percent are in the poorest quintile the propensity score matching psm estimator is reasonably robust to a number of changes in methodology participants are more likely to be poor than non participants participants are less well educated live in poorer neighborhoods and are more likely to be members of neighborhood associations and political parties average gains are similar between men and women but are higher for younger workers funding for the study derives from the world bank research committee

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

the life cycle model of consumption and saving a central implication of life cycle models is that agents smooth consumption we review the empirical evidence on smoothing at frequencies from within the year up to across a lifetime we find that life cycle models particular those which incorporate realistic features of markets and goods have more empirical successes than failures we also show that some apparent deviations from theoretical predictions imply very small welfare losses for agents finally we emphasize that the coherence of life cycle models imposes an important discipline when incorporating new features into models

sensitivity to market incentives the case of policy loans the standard neoclassical theory is rejected as an explanation for the observed reluctance of most holders of whole life insurance to borrow against the cash value of their policies at favorable rates of interest even when the neoclassical theory is augmented with transactions costs and short awareness lags several empirical tests using survey and time series data reject the standard theory in favor of an explanation invoking self imposed rules against borrowing or the debt ethic this evidence lends support to the psychology based theories of thaler and shefrin 1981 copyright 1987 by mit press

mental accounting access motives and overinsurance people exercising mental accounting have an additional motive for buying insurance they perceive a risk of having insu cient funds available to self insure in this way insurance protects the consumption value of the insured asset beyond the expenditure to acquire replace it this complements previous approaches based on probability weighting and loss aversion to explain the high pro tability of warranties and an aversion toward deductibles it helps to account for why the value of a warranty is found to be positively related to the value of the product and why there is seemingly contradictory empirical evidence on how household income a ects demand for warranties the adapted model rationalizes a strong aversion to deductibles and explains the observed sensitivity of this aversion to the insurance context finally it predicts a strong impact of how an insurer pays out bene ts on the value and cost of insurance this can explain both the evidence on strong deductible aversion for ood insurance and the lack of such evidence for long term care insurance jel classi cation d11 d14 d81 g22

further evidence of excess sensitivity of consumption nonseparability among goods and heterogeneity across households the standard theoretical framework for analysing households intertemporal decisions is the life cycle permanent income model among its implications testing the model allows to analyse the response of consumption to fiscal policy however the empirical literature with microdata has yielded mixed results this article examines the sensitivity of the results to the assumption of separability among goods and of homogeneity across households for that purpose we test a rational expectations permanent income model with household data drawn from the spanish family expenditure survey this survey contains detailed information on total expenditure and the income presents large exogenous quarterly changes due to an institutional feature the article shows that assuming separability among commodities biases the test against the model when separability is not imposed we show that the rejection of the model depends on heterogeneity across households in terms of their members being unemployed or not for those

parental net wealth and personal consumption this paper uses data from the 1988 to 1991 psid to examine the relationship between parental net wealth and consumption behavior of adult children in a model where the probability of receiving a future transfer from the parent is an increasing function of the level of parental net wealth a non linear relationship is expected the results in this study are consistent with such a relationship parental net wealth is found to have a positive influence on children s consumption only at very high levels in addition this relationship appears to apply only to parental housing wealth and not parental non housing wealth

mental accounting in portfolio choice evidence from a flypaper effect this paper documents a lack of coordination between the asset allocations of different financial accounts in a household portfolio our findings are predicted by the theory of mental accounting richard h thaler 1985 1990 1999 agents sometimes make decisions about individual accounts in their portfolio without considering their other accounts the setting for our analysis is a large u s firm when an employee at this firm makes a 401 k contribution the company makes a matching contribution proportional to the employee s contribution up to a match threshold in march 2003 the firm changed its 401 k matching rules creating a natural experiment both before and after the rule change the initial allocation of participants own contribution flows was determined by the participants 1 the change in march 2003 was to the policy determining the initial asset allocation of the employer match contributions in the first regime before march 2003 the firm directed matching contribution flows entirely into employer stock this was not a binding restriction as participants could freely reallocate their match balances after matching contributions were made although in practice participants rarely did so in march 2003 the company changed its match policy requiring new enrollees to actively choose the asset allocation for both their own and match contribution flows the change between these regimes was economically neutral any allocation of balances in one regime could be replicated in the other nevertheless allocations to employer stock differed vastly across the two regimes employees who enrolled in february 2003 just before the regime change allocated 23 of their own contribution flows to employer stock since all of their match contributions were directed into employer stock this resulted in a 56 total 401 k allocation to employer stock combining the own contribution and match contribution accounts few of these february enrollees made subsequent trades to reduce their employer stock balances in either account employees who enrolled in march 2003 right after the change allocated 23 of their total own plus match contribution flows to employer stock notice that own contribution allocations to employer stock in the first regime precisely match the combined allocation of own and match contributions in the second regime 23 in both cases even though combined allocations differ greatly across the regimes these results imply that each dollar of employer stock contributed to enrollees through the match in the first regime increased the employees total holdings of employer stock by a full dollar rather than being offset by reduced employer stock holdings elsewhere or being sold off directly in other words money sticks where it hits a phrase attributed to arthur okun generating an asset allocation flypaper effect that is akin to the flypaper effects of public finance corporate finance and intra household consumption 2 after considering several explanations for the asset allocation flypaper effect we conclude that it is due in part to mental accounting our results can be explained by the following simple model in the first regime new enrollees actively allocated only their own contribution flows effectively ignoring the fact that their matching contributions were entirely directed into employer stock in the second regime the match allocation became salient because new enrollees were required to choose both their match and own contribution allocations during the enrollment process this caused enrollees to consider their entire 401 k portfolio instead of just their own contribution accounts as a result the fraction of total contributions allocated to employer stock under the second regime equaled the fraction of own contribution flows allocated to employer stock under the first regime the average participant allocated roughly one quarter of assets to employer stock in whatever accounts were salient whether the set of salient accounts was narrow regime one or broad regime two the dependence of portfolio outcomes on account salience is inconsistent with investors having a clear target asset allocation for their entire portfolio which they efficiently implement through their investment choices in accordance with much prior research we also find that investors are quite passive rarely reallocating their portfolios 3 however our central finding concerns asset allocation decisions made at enrollment a point when people have overcome their passivity and are taking action investor passivity thus cannot account for the unresponsiveness of own contribution allocations to the match allocation at enrollment under the first regime although passivity helps explain why these initial decisions are rarely reversed subsequently

aging and the income value of housing wealth abstract the potential of reverse annuity mortgages to increase the current income of the elderly is analyzed we conclude that most low income elderly also have little housing equity in general a reverse annuity mortgage would substantially affect the income only of the single elderly who are very old whose life expectancy is short on the other hand if the transfer were in the form of a lump sum payment rather than an annuity the payment would increase the liquid wealth of most elderly families by a large fraction thus legislation that would facilitate the market for reverse mortgages could improve substantially the financial status of a small proportion of the elderly

the response of household consumption to income tax refunds a central implication of the life cycle or permanent income theory is that consumption should not respond to predictable fluctuations in income tests of this implication have yielded mixed results especially on micro data angus deaton 1992 martin browning and annamaria lusardi 1996 in large part this might be due to the difficulties of isolating the predictable component of income at the micro level most tests proceed by instrumenting for income but since the available instruments are typically poor such tests might be prejudiced against finding significant excess sensitivity of consumption to income john shea 1995 also it is not clear how closely the resulting econometric predictions of income coincide with agents actual expectations of income to avoid these difficulties this paper examines the response of household consumption to a particular type of income that is both predictable and transitory income tax refunds since a refund depends on events in the previous calendar year it is predictable income as regards consumption in the year of its receipt consequently under the life cycle theory consumption should not increase on receipt of a refund 2 in addition to testing the canonical model of consumption this paper provides estimates interpretable as the marginal propensity to consume mpc out of refunds since federal tax refunds now amount to over 80 billion per year averaging well over 1 000 per refund these estimates are of interest in themselves more generally they bear on the impact of even preannounced and temporary changes in fiscal policy the paper begins by surveying related studies in section i section ii describes the data the consumer expenditure survey cex which of the leading u s micro data sets has the most comprehensive coverage of expenditure the empirical specification is set out in section hi section iv reports the results and section v concludes

the effects of pensions on household wealth a reevaluation of theory and evidence this paper examines the extent to which households offset pension wealth with reductions in other wealth systematic econometric biases imply that the estimated offsets in previous empirical studies are smaller than the true offset and may even have the wrong sign new empirical estimates that do not correct for the biases generate little offset between pensions and other wealth estimates that correct for the biases show substantially more offset a smaller impact of pensions on overall saving than in most previous studies the estimates also indicate that the effects of pensions on wealth vary significantly across households

does purchase price matter for the waiting time to start using energy efficient technologies experimental evidence from rural ethiopia abstract in this study we conducted a randomized experiment in rural ethiopia to test on how quickly energy efficient technology an improved stove is put in use after the technologies is disseminated we evaluate two concepts that may affect usage of a product screening related to valuation of a product and sunk cost effects based on the price the potential user paid for the product a standard tobit and iv tobit methods of estimations are used for testing sunk cost and screening effects respectively results based on the baseline survey and follow up data shows that there is no difference in the length of waiting time to start using the energy efficient technology between those who got the stove for free and those that paid money for it in other words the sunk cost effect is absent however we find a difference in the waiting time between those with high valuation for the stove and those with lower valuation for it in other words we find an evidence of the screening effect the result has pricing policy implications for government and non government organizations involved in dissemination of such technologies that have both public environmental and private benefits

saving in developing countries theory and review in the literature on economic development much of the interest in saving has been focused on the relation between saving and growth but saving is not only about accumulation it is about smoothing consumption in the face of volatile and unpredictable income and helping to ensure the living standards of poor people whose lives are difficult and uncertain this paper develops a model of households which cannot borrow but which accumulate assets as a buffer stock to protect consumption when incomes are low such households dissave as often as they save do not accumulate assets over the long term and have on average very small asset holdings but their consumption is markedly smoother than their income much of the evidence is as consistent with this view of saving as it is incosistent with standard views of smoothing over the life cycle and with explanations of the link between saving and growth in terms of life cycle saving behavior consumption smoothing is also a useful way of thinking about government policy where volatility in the world prices of taxed commodities can generate sharp fluctuations in government revenues as well as reallocations of revenue between the private and public sectors many important policy issues in developing countries hinge on issues of consumption and smoothing and research on these issues is currently likely to be more productive than work on the relation between saving and growth

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

imprecise preferences and survey design in contingent valuation during recent years the contingent valuation cv method has been widely used to value non marketed goods and services we present the results of a cv study of the value of road safety we find that stated preferences for road safety exhibit considerable imprecision appear subject to various systematic biases and are insensitive to variations in the quantity and quality of the safety improvements concerned one broad implication of these findings may be that for an important class of goods of which safety is one example standard assumptions about the structure of people s preferences may be much too strong a more specific implication concerning the design and conduct of cv surveys is that the noaa panel s widely cited blueprint for good cv practice may rely far too heavily on assumptions about the precision and sensitivity of people s preferences

the benefits of emergency reserves greater preference and persistence for goals that have slack with a cost abstractmarketers of programs that are designed to help consumers reach goals face dual challenges of making the program attractive enough to encourage consumer signup while still motivating consumers to reach desirable goals and thus stay satisfied with the program the authors offer a possible solution to this challenge the emergency reserve or slack with a cost they demonstrate how an explicitly defined emergency reserve not only is preferred over other options for goal related programs but can also lead to increased persistence study 1 demonstrates that consumers prefer programs with emergency reserves to programs that do not have them and study 2 further clarifies that consumers preference for an emergency reserve depends on the presence of a superordinate goal study 3 reveals that consumers prefer goals with emergency reserves because they perceive them to have both higher attainability and value than other goals study 4 demonstrates that reserves can lead to increased goal persistence in a

private pensions mortality risk and the decision to annuitize abstract this paper examines household decisions about whether or not to annuitize retirement resources a life cycle model of consumption implemented with the use of dynamic programming techniques is used to construct a utility based measure of annuity value for individuals and couples in the health and retirement survey variation in the calculated annuity equivalent wealth arises from differences in mortality risk marital status risk aversion and the presence of pre existing annuities such as social security i find that a one percentage point increase in the annuity equivalent wealth leads to nearly a one percentage point increase in the ex ante probability of annuitizing balances in defined contribution pension plans however because much of the variation in the expected annuity decision is left unexplained by the life cycle model other factors are also analyzed health status and an individual s time horizon for financial decision making are significant determinants of the decision there is no evidence that bequest motives are an important factor in making marginal annuity decisions

stock market wealth and consumption this paper explores the link between changes in the aggregate value of corporate stock and changes in consumer spending it presents data on the distribution of corporate stock ownership based on the 1998 survey of consumer finances it also uses time series evidence on the comovement of stock market wealth and various categories of consumer spending to calibrate the wealth effect it concludes that in the year after a change in stock market values consumer spending is likely to rise by between one and two cents for each dollar increase in the value of corporate stock

did tax flattening affect rrsp contributions in 1988 marginal personal income tax rates changed in canada for some individuals by reasonably substantial amounts in this note a large sample of tax filer data is examined and the conclusion is drawn that when attention is paid to the possible confounding of marginal tax rate and non linear income effects there is no convincing evidence that the tax rate changes affected contributions to registered retirement saving plans rrsps est ce que l aplatissement des taux d imposition influence les contributions au reer en 1988 les taux marginaux d imposition du revenu personnel ont change au canada et pour certaines personnes ces changements ont ete substantiels cette note examine un grand echantillon de rapports d impots et en arrive a la conclusion que quand on prend en compte le melange possible des effets du taux marginal d imposition et des effets de revenu non lineaires il n y a pas de resultats qui montrent de facon probante que les changements dans les taux d imposition ont influence les contributions au reer
