anticipating regret why fewer options may be better we study preferences over menus which can be represented as if the agent selects an alternative from a menu and experiences regret if her choice is ex post inferior since regret arises from comparisons between the alternative selected and the other available alternatives our axioms reflect the agent s desire to limit her options we prove that our representation is essentially unique we also introduce two measures of comparative regret attitudes and relate them to our representation finally we explore the formal connection between the present work and the literature on temptation

market approval of phytosanitary active substances in europe an empirical duration analysis abstract the aim of this paper is to analyze empirically the main determinants of delays to market approval of active substances in europe an interesting feature of this regulation is that it is based on both a decentralized examination by the rapporteur country and a centralized examination by the european food safety authority efsa our econometric analysis is based on standard survival and competing risks models the data cover 393 active substances reviewed between 1993 and 2013 we show that the review process is affected by regulatory factors the characteristics of the active substances and the characteristics of agri chemical firms log logistic and log normal survival models are the preferred parametric specifications and the results suggest that the hazard function is non monotonic over time

choice proliferation simplicity seeking and asset allocation abstract in settings such as investing for retirement or choosing a drug plan individuals typically face a large number of options in this paper we analyze how the size of the choice set influences which alternative is selected we present both laboratory experiments and field data that suggest larger choice sets induce a stronger preference for simple easy to understand options the first experiment demonstrates that in seeming violation of the weak axiom of revealed preference subjects are more likely to select a given sure bet over non degenerate gambles when choosing from a set of 11 options than when choosing from a subset of 3 the second experiment clarifies that large choice sets induce a preference for simpler rather than less risky options lastly using records of more than 500 000 employees from 638 institutions we demonstrate that the presence of more funds in an individual s 401 k plan is associated with a greater allocation to money market and bond funds at the expense of equity funds

how product standardization affects choice evidence from the massachusetts health insurance exchange this paper examines the effect of choice architecture on massachusetts health insurance exchange a policy change standardized cost sharing parameters of plans across insurers and altered information presentation post change consumers chose more generous plans and different brands but were not more price sensitive we use a discrete choice model that allows the policy to affect how attributes are valued to decompose the policy s effects into a valuation effect and a product availability effect the brand shifts are largely explained by the availability effect and the generosity shift by the valuation effect a hypothetical choice experiment replicates our results and explores alternative counterfactuals

reinventing public r d patent policy and the commercialization of national laboratory technologies when innovations are heterogeneous it may be advantageous to provide a variety of patents by trading off patent breadth for length it is possible that fees are not needed in the optimal policy we present two examples the first is a quality ladder model in which innovations benefit society directly as well as through their use as building blocks to future inventions and the rate of arrival for the future innovation is unobserved more fertile innovations get more breadth for a shorter time menus may also be useful in the case of horizontal product differentiation copyright 2001 by the rand corporation

personal traits and individual choices taking action in economic and non economic decisions abstract in a large number of decisions the option that does not require a specific action such as filling in a form is chosen frequently it is a stylized fact that opt in or opt out designs for otherwise identical choices lead to vastly different outcomes choice options are chosen more frequently simply because they are the no action alternative or default option however direct empirical evidence on the reasons for the popularity of defaults is scarce we devised a special survey module for the dutch dnb household survey to study potential explanations for default choices we find that the popularity of the default option is related to different personal traits in economic and non economic decisions financially literate individuals are more likely to take action and opt out the default option in economic decision making in non economic decisions procrastination increases the popularity of the default while individuals who care much about the opinion of others are more inclined to deviate from the default

the impact of local unemployment rates on reservation wages and the duration of search for a job evidence about the relationship of local unemployment rates and individuals reservation wages and duration of search for a job if unemployed is sparse and mixed this study uses us data from the panel study of income dynamics psid to test whether relatively high local unemployment rates reduce the reservation wages of area residents or increase the duration of search labour search theory provides the grounding for the sample selection corrected simultaneous equations econometric model in neither ols nor 2sls results is evidence found that local unemployment rates affect either reservation wages or the duration of search these results suggest that policies targeted at alleviating unemployment should focus on increasing the demand for labour rather than hope that such policies will be beneficial if pursued in high unemployment areas because of their effects on labour force characteristics

the effect of ordering decisions by choice set size on consumer search consumers frequently engage in sequential decisions this article explores whether the order of these decisions can influence the manner in which consumers search through the possible choice options results from five studies suggest that ordering decisions by increasing vs decreasing choice set size leads to greater search depth measured by both sampling count and decision time initial smaller choice sets in increasing sequences appear to initiate a maximizing mind set which then persists even as participants encounter later larger choice sets these participants report a greater desire to maximize and are less satisfied with their decisions consistent with research on chronic maximizers in addition they continue to exhibit maximizing behavior in subsequent unrelated tasks supporting a mind set account of the differences in search in sum decision makers are proposed to be sticky adapters initial decision strategies seem to constrain the extent to which they adapt to new contexts

the questionable value of having a choice of levels of health insurance coverage in most health insurance markets in the united states consumers have substantial choice about their health insurance plan however additional choice is not an unmixed blessing as it creates challenges related to both consumer confusion and adverse selection there is mounting evidence that many people have difficulty understanding the value of insurance coverage like evaluating the relative benefits of lower premiums versus lower deductibles also in most us health insurance markets people cannot be charged different prices for insurance based on their individual level of health risk this creates the potential for well known problems of adverse selection because people will often base the level of health insurance coverage they choose partly on their health status in this essay we examine how the forces of consumer confusion and adverse selection interact with each other and with market institutions to affect how valuable it is to have multiple levels of health insurance coverage available in the market

ballot position choice fatigue and voter behaviour in this paper we examine the eect of choice fatigue on decision making we exploit a natural experiment in which voters face the same contest at dierent ballot positions due to dierences in the number of local issues on their ballot facing more decisions before a given contest signi cantly increases the tendency to abstain or rely on decision shortcuts such as voting for the status quo or the rst listed candidate we estimate that without choice fatigue abstentions would decrease by 8 and 6 of the propositions in our dataset would have passed rather than failed

heterogeneity in choice inconsistencies among the elderly evidence from prescription drug plan choice abstract this paper investigates the degree to which choice inconsistencies documented in the context of medicare part d plan choice vary across consumers and geographic regions our main finding is that there is surprisingly little variation regardless of age gender predicted drug expenditures or the predictability of drug demand consumers underweight out of pocket costs relative to premiums and fail to consider the individualized consequences of plan characteristics as a result they frequently choose plans which are dominated in the sense that an alternative plan provides better risk protection at a lower cost we find limited evidence that the sickest individuals had more difficulty with plan choice and we document that much of the variation in potential cost savings across states comes from variation in choice sets not variation in consumers ability to choose

a survey of the economics of patent systems and procedures the last several decades have seen increases in patenting activity worldwide as well as growing issues related to patent quality in response to these quality issues a recent patent literature has emerged that investigates the behavior and incentives of patent examiners applicants and third parties in this paper we provide an overview of patent procedures patent systems and a survey of the new economic literature on patent systems both theoretical and empirical papers are considered policy implications coming from this literature are presented

price competition with consumer confusion this paper proposes a model in which identical sellers of a homogenous product compete in both prices and price frames i e ways to present price information we model price framing by assuming that firms frame choices affect the comparability of their price offers consumers may fail to compare prices due to frame differentiation and due to frame complexity in the symmetric equilibrium the firms randomize over both price frames and prices and make positive profits this result is consistent with the observed coexistence of price and price frame dispersion in the market we also show that i the nature of equilibrium depends on which source of consumer confusion dominates and ii an increase in the number of firms can increase industry profits and harm consumers

naive diversification strategies in defined contribution saving plans there is a worldwide trend toward defined contribution saving plans and growing interest in privatized social security plans in both environments individuals are given some responsibility to make their own asset allocation decisions raising concerns about how well they do at this task this paper investigates one aspect of the task namely diversification it is shown that some investors follow the 1 n strategy they divide their contributions evenly across the funds offered in the plan consistent with this naive notion of diversification it is found that the proportion invested in stocks depends strongly on the proportion of stock funds in the plan

selection on observed and unobserved variables assessing the effectiveness of catholic schools in this paper we measure the effect of catholic high school attendance on educational attainment and test scores because we do not have a good instrumental variable for catholic school attendance we develop new estimation methods based on the idea that the amount of selection on the observed explanatory variables in a model provides a guide to the amount of selection on the unobservables we also propose an informal way to assess selectivity bias based on measuring the ratio of selection on unobservables to selection on observables that would be required if one is to attribute the entire effect of catholic school attendance to selection bias we use our methods to estimate the effect of attending a catholic high school on a variety of outcomes our main conclusion is that catholic high schools substantially increase the probability of graduating from high school and more tentatively attending college we find little evidence of an effect on test scores

poverty and economic decision making evidence from changes in financial resources at payday we study the effect of financial resources on decision making low income u s households are randomly assigned to receive an online survey before or after payday the survey collects measures of cognitive function and administers risk and intertemporal choice tasks the study design generates variation in cash checking and savings balances and expenditures before payday participants behave as if they are more present biased when making intertemporal choices about monetary rewards but not when making intertemporal choices about non monetary real effort tasks nor do we find before after differences in risk taking the quality of decision making the performance in cognitive function tasks or in heuristic judgments

regimen changes and duration in the european monetary system this article examines the regime changes in the exchange rate mechanism erm of the european monetary system ems applying the duration model approach to weekly data of eight currencies participating in the erm covering the complete ems history when using the non parametric univariate analysis it was found that for those regimens with long durations the erm would have been relatively stable while for the more common regimes associated with short durations would have been more unstable the probability of maintaining a certain regime is estimated to be 0 685 when applying a parametric multivariate analysis to investigate the role of other variables in the probability of a regime change it is concluded that the interest rate differential with germany and the magnitude of the realignment would have negatively affected the duration of a given regime while credibility would have positively influenced such duration finally when distinguishing between groups of currencies it is observed that

duopolistic competition with choice overloaded consumers a large body of experimental work has suggested the existence of a choice overload effect in consumer decision making faced with large menus of choice options decision makers often defer or avoid choice a suggested reason for the occurrence of this effect is that the agents attempt to avoid the cognitive effort that is associated with choosing from larger menus building on this explanation we propose and analyse a model of duopolistic competition where firms compete in menu design in the presence of a consumer population with heterogeneous preferences and overload menu size thresholds the firms strategic trade off is between offering a large menu in order to match the preferences of as many consumers as possible and offering a small menu in order to avoid losing choice overloaded consumers to their rival assuming uniformly distributed preferences we focus on symmetric pure strategy equilibria under various assumptions on the overload distribution and product markups we also propose and analyse a measure of consumer welfare that applies to this environment among other things we provide conditions for maximum and minimum variety equilibria to be possible whereby both firms either offer the entire set of available products or the same one product respectively

health insurance choice and risk preferences under cumulative prospect theory an experiment we investigate how consumers choose insurance contracts when using a measure of decision quality based on individual risk preferences for this we use a laboratory experiment with a sequential design first subjects face insurance choices then we elicit risk preferences allowing for different latent decision making theories i e cumulative prospect theory and expected utility theory we find that the vast majority are cumulative prospect theory types analyzing whether subjects choose contracts consistent with their risk preferences we find that about 14 of all participants show inconsistent behavior and low decision quality yet the majority shows consistent behavior and good decision quality our results suggest that one explanation for inconsistent choices is the application of heuristics

individual account investment options and portfolio choice behavioral lessons from 401 k plans abstract this paper examines how the menu of investment options made available to workers in defined contribution plans influences portfolio choice using unique panel data of 401 k plans in the u s we present three principle findings first we show that the share of investment options in a particular asset class i e company stock equities fixed income and balanced funds has a significant effect on aggregate participant portfolio allocations across these asset classes second we document that the vast majority of the new funds added to 401 k plans are high cost actively managed equity funds as opposed to lower cost equity index funds third because the average share of assets invested in low cost equity index funds declines with an increase in the number of options average portfolio expenses increase and average portfolio performance is thus depressed all of these findings are obtained from a panel data set enabling us to control for heterogeneity in the investment preferences of workers across firms and across time

small cues change savings choices we present evidence from randomized field experiments that 401 k savings choices are significantly affected by one to two sentence anchoring goal setting or savings threshold cues embedded in emails sent to employees about their 401 k plan even though these cues contain little to no marginal information cues that make high savings rates salient increased 401 k contribution rates by up to 2 9 of income in a pay period and cues that make low savings rates salient decreased 401 k contribution rates by up to 1 4 of income in a pay period cue effects persist between two months and a year after the email

product variety and endogenous pricing with evaluation costs one important decision firms must make is to select the product line characteristics and number of products to offer consumers this paper explores the effect of the interaction between consumer evaluation costs and pricing on the optimal product line length to offer consumers before deciding to buy a product among all products offered a consumer learns the product line length given the product line length a consumer decides whether to evaluate the products available and their prices this decision to evaluate depends on the expected consumer surplus after the evaluation being greater than the evaluation costs when the firm offers few products the firm may not attract many consumers because of lack of product fit and may be forced to offer low prices when the firm offers many products all consumers will find a great product fit that is the variance of consumer valuations per product chosen is lower this allows the firm to charge high prices to extract ex post consumer surplus resulting in lower ex ante expected consumer surplus which may lead consumers not to evaluate the products in the first place that is by offering fewer products a firm can commit not to extract all possible consumer surplus these two forces may then lead to the existence of an interior optimal number of products to offer the optimal number of products offered is decreasing in the evaluation costs

what makes annuitization more appealing we conduct and analyze two large surveys of hypothetical annuitization choices we find that allowing individuals to annuitize a fraction of their wealth increases annuitization relative to a situation where annuitization is an all or nothing decision very few respondents choose declining real payout streams over flat or increasing real payout streams of equivalent expected present value highlighting the effects of inflation increases demand for cost of living adjustments frames that highlight flexibility control and investment significantly reduce annuitization a majority of respondents prefer to receive an extra bonus payment during one month of the year that is funded by slightly lower payments in the remaining months concerns about later life income spending flexibility and counterparty risk are the most important self reported motives that influence the annuitization decision

the impact of sectoral shifts and the aggregate labour market on unemployment duration this study investigates the effects of sectoral shifts among industries on unemployment duration these effects are decomposed into two subeffects the overall effect and the specific industrial effect the former is equal for all of the unemployed in all industries while the latter depends on the tightness of the demand for labour of the industry in question in addition the impact of the aggregate labour market on unemployment duration is also explored the empirical results show that most of the overall and all of the specific effects are significant indicating that the sectoral shifts among industries as well as the aggregate labour market do in fact impact unemployment duration and that the effects on unemployment duration vary in terms of their tightness in the different industrial labour markets

institutional and individual investors saving for old age this paper brings together the academic literature on individual and institutional investors in order to understand the nature of difficulties faced by them and set the background for the special issue this introductory article and the papers in the special issue contribute to the debate on how to support individuals in their savings commitments and investment decision making and whether and how institutional investors have fulfilled their role in supporting the development of the funded pension industry there are three main conclusions i individual investors are not ready for the role that has been assigned to them in the pension industry ii institutional investors are a long way short of establishing healthy relational contracts and trustworthy relationships with their clients and iii more effective regulation may be needed

contextual inference in markets on the informational content of product lines context can influence decisions this malleability of choice is usually invoked as evidence that people do not maximize stable preference orderings in a market equilibrium however context conveys payoff relevant information to consumers consequently these consumers rationally violate naive formulations of standard choice theoretic principles i identify informational asymmetries under which apparently anomalous behaviors namely the compromise effect and choice overload arise as market equilibria firms respond to consumers contextual inference in case of the compromise effect a firm may introduce premium loss leaders expensive goods of overly high quality that increase the demand for other goods

lottery rationed public access under alternative tariff arrangements changes in quality quantity and expected utility abstract a recent phenomenon is the emergence of quotas restricting individual access to public resources as regulators commonly ration access opportunities by lottery this paper extends the traditional open access destination choice framework for non market demand and welfare analysis conceptual results for one and two part tariff lotteries indicate that individuals may sustain welfare losses from improvements in quality or increases in the quota if aggregate demand is sufficiently responsive relative to individual utility nested random expected utility models reums are estimated with a panel dataset of individual choices of lottery rationed harvest rights for wild game empirical results indicate that the types and timing of tariff payments affect participation choices over rationed and open access alternatives and the benefits derived from changes in the quality and quantity of the lottery rationed access opportunities

financial literacy financial education and downstream financial behaviors policy makers have embraced financial education as a necessary antidote to the increasing complexity of consumers financial decisions over the last generation we conduct a meta analysis of the relationship of financial literacy and of financial education to financial behaviors in 168 papers covering 201 prior studies we find that interventions to improve financial literacy explain only 0 1 of the variance in financial behaviors studied with weaker effects in low income samples like other education financial education decays over time even large interventions with many hours of instruction have negligible effects on behavior 20 months or more from the time of intervention correlational studies that measure financial literacy find stronger associations with financial behaviors we conduct three empirical studies and we find that the partial effects of financial literacy diminish dramatically when one controls for psychological traits that have been omitted in prior research or when one uses an instrument for financial literacy to control for omitted variables financial education as studied to date has serious limitations that have been masked by the apparently larger effects in correlational studies we envisage a reduced role for financial education that is not elaborated or acted upon soon afterward we suggest a real but narrower role for just in time financial education tied to specific behaviors it intends to help we conclude with a discussion of the characteristics of behaviors that might affect the policy maker s mix of financial education choice architecture and regulation as tools to help consumer financial behavior this paper was accepted by uri gneezy behavioral economics

on optimal congestion abstract a number of classic papers conclude that if a congestible facility is the property of a profit maximizing entrepreneur he will impose a charge for use that induces the socially optimal level of use and congestion all these papers happen to deal with a special case in which that conclusion holds but it is not true in general in general the socially optimal level of use of a congestible facility is the level at which the marginal cost of providing the service is equal to the sum of the decreases in the users willingnesses to pay for a unit of service when the level of congestion is optimal and need not coincide with the level resulting from a profit maximizing charge this sum is derived from the integral under a fictitious demand curve constructed by imagining that the level of congestion is the same and optimal at all levels of the use charge

offering versus choice in 401 k plans equity exposure and number of funds records of over half a million participants in more than 600 401 k plans indicate that participants tend to allocate their contributions evenly across the funds they use with the tendency weakening with the number of funds used the number of funds used typically between three and four is not sensitive to the number of funds offered by the plans which ranges from 4 to 59 a participant s propensity to allocate contributions to equity funds is not very sensitive to the fraction of equity funds among offered funds the paper also comments on limitations on inferences from experiments and aggregate level data analysis how much and how to save for retirement is one of the most important financial decisions made by most people defined contribution dc pension plans such as the popular 401 k plans are important instruments of such savings by 2001 year end about 45 million american employees held 401 k plan accounts with a total of 1 75 trillion in assets holden and vanderhei 2001 an important characteristic of these plans is that the participant has responsibility over his savings among a plan s various funds how responsibly do the participants behave in particular how sensitive are participants choices to possible framing effects associated with the menu of choices they are offered to explore these questions this paper analyzes a data set recently provided by the vanguard group consisting of records of more than half a million participants in about 640 dc plans these plans offer between 4 and 59 funds in which participants can invest all plans offer at least one stock fund 635 plans

choice inconsistencies among the elderly evidence from plan choice in the medicare part d program we evaluate the choices of elders across their insurance options under the medicare part d prescription drug plan using a unique data set of prescription drug claims matched to information on the characteristics of choice sets we document that elders place much more weight on plan premiums than on expected out of pocket costs value plan financial characteristics beyond any impacts on their own financial expenses or risk and place almost no value on variance reducing aspects of plans partial equilibrium welfare analysis implies that welfare would have been 27 higher if patients had all chosen rationally

a survival analysis of the approval of us patent applications we model the length of time that it takes for a patent application to be granted by the us patent and trademark office uspto conditional on the patent actually being awarded eventually survival analysis is applied and both the nonparametric kaplan meier and parametric accelerated failure time models are used to analyse the data we find that the number of claims a patent makes the number of citations a patent makes the patent s technological category and the type of applicant all have significant effects on the duration that a patent is under consideration a log normal survival model is the preferred parametric specification and the results suggest that the hazard function is nonmonotonic over time

the discriminating consumer product proliferation and willingness to pay for quality abstract the authors propose that a crowded product space motivates consumers to better discriminate between options of different quality specifically this article reports evidence from three controlled experiments and one natural experiment that people are prepared to pay more for high quality products and less for low quality products when they are considered in the context of a dense as opposed to a sparse set of alternatives to explain this effect the authors argue that consumers uncertain about the importance of quality learn from observing market outcomes product proliferation reveals that other consumers care to discriminate among similar alternatives and in turn this inference raises the importance of quality in decision making

modelling the duration of interest rate spells under inflation targeting in canada we use survival models to analyse the duration of the spells associated with the interest rate used by the bank of canada as its monetary policy instrument both nonparametric and parametric models are estimated allowing for right censoring of the data and time varying covariates we find that the data are explained well by an accelerated failure time weibull model with the annual rate of inflation and the quarterly rate of growth in gross domestic product gdp as covariates the model indicates that there is positive duration dependence in the interest rate spells and that unemployment and exchange rate effects are insignificant

optimal defaults and active decisions defaults often have a large influence on consumer decisions we identify an overlooked but practical alternative to defaults requiring individuals to make an explicit choice for themselves we study such active decisions in the context of 401 k saving we find that compelling new hires to make active decisions about 401 k enrollment raises the initial fraction that enroll by 28 percentage points relative to a standard opt in enrollment procedure producing a savings distribution three months after hire that would take 30 months to achieve under standard enrollment we also present a model of 401 k enrollment and derive conditions under which the optimal enrollment regime is automatic enrollment i e default enrollment standard enrollment i e default non enrollment or active decisions i e no default and compulsory choice active decisions are optimal when consumers have a strong propensity to procrastinate and savings preferences are highly heterogeneous financial illiteracy however favors default enrollment over active decision enrollment
