micro vs macro explanations of post war us unemployment movements abstract this paper considers contributions of industry sectoral micro shocks vs aggregate macro shocks a dynamic factor model is estimated with maximum likelihood method in the frequency domain and decomposes us unemployment movements into industry sectoral and common components sectoral shocks account for around half unemployment movements

the role of information on retirement planning evidence from a field study i introduction modern financial planning is dominated by discussions of one topic retirement savings retirement planning behaviors are widely studied yet population data show perplexing patterns of savings especially among households who reasonably should expect to live long and healthy lives after separating from the workforce savings choices are increasingly focused on the decisions of individuals rather than on public plans or employer mandated pensions poterba 2014 however policymakers attempts to stimulate more individual level savings have not shown strong effects duflo et al 2007 one problem appears to be related to people failing to fully plan ahead for retirement and neglecting longer run financial management in general ameriks caplin and leahy 2003 according to the employee benefit research institute 2015 more than one in four workers have less than 1 000 in retirement savings fewer employees today have access to defined benefit pensions than they did in the past and instead rely on employer based 401 k savings accounts and nonemployer based individual retirement accounts iras munnell 2006 however participation rates remain low 43 of private sector workers of age 25 64 take part in retirement savings programs calabrese 2011 even among active savers there are concerns about how well people are able to manage their retirement accounts in ways that reflect optimal planning horizons several policies have been designed to increase participation in retirement plans first firm level programs requiring employees to opt out vs opt in to a 401 k plan have increased participation in retirement savings plans madrian and shea 2001 however as choi laibson and madrian 2011 highlight because individuals have heterogeneous savings preferences these default options may be costly to individuals as some might save more in the absence of the default and others might prefer to save less second government designed tax breaks for individuals investing in retirement accounts and increases in maximum income deferral limits for these accounts could increase retirement savings however income tax deductions and credits can be costly tax expenditures and individuals especially lower and middle income savers may not respond to these incentives engen gale and scholz 1996 third firms can try to help people better understand their savings options and make plans for retirement effectively lowering the costs of information with workshops and or counseling retirement planning requires information in order to form expectations about lifetime income years of work expected investment returns adjusted for risk and consumption levels in retirement people who lack information about these issues may fail to make a plan or proceed to design a plan based on incomplete information educational programs targeted to workers hold promise to help people recalibrate their expectations and shift their savings behavior well targeted financial education might facilitate people to pursue their individual retirement saving preferences in ways that default rules or incentives alone cannot this article studies the effect of financial education on retirement savings offered to employees in an online format online information offers several advantages over traditional seminars for example online courses can be delivered to a large audience and at a lower cost per participant than classroom delivery it also poses relatively low marginal costs to the employee because of the flexibility and convenience of the mode of delivery it may serve employees who would not attend in person sessions while participants in online education do not benefit from group interactions online delivery provides participants privacy to explore financial issues that they might shy away from in more public settings several studies document that employer based education is associated with improvements in employees financial knowledge clark and d ambrosio 2002 holland goodman and stich 2008 skimmyhorn forthcoming

a new method of estimating risk aversion i show existing evidence on labor supply behavior places an upper bound on risk aversion in the expected utility model i derive a formula for the coefficient of relative risk aversion in terms of the ratio of the income elasticity of labor supply to wage elasticity and degree of complementarity between consumption and labor i bound the degree of complementarity using data on consumption choices when labor supply varies across states using labor supply elasticity estimates i find a mean estimate of 1 then show generating 2 requires that wage increases cause sharper labor supply reductions jel d81 j22

the link between pensions and retirement timing lessons from california teachers abstract i exploit a major unanticipated reform of the california teachers pension to provide quasi experimental evidence on the link between pension features and retirement timing using two large administrative data sets i conduct a reduced form analysis that leverages the nonlinearities in the return to work generated by the pension features and the reform induced shifts of these nonlinearities for identification the implied estimates of the elasticity of lifetime labor supply with respect to the return to work are centered around 0 04 in the medium run and are less than 0 1 in the long run

why do parents socialize their children to behave pro socially an information based theory we present a model of intergenerational transmission of pro social values in which parents have information about relevant characteristics of society that is not directly available to their children dierently from existing models of cultural transmission of values such as bisin and verdier 2001 and tabellini 2008 we assume that parents are exclusively concerned with their children s material welfare if parents coordinate their educational choices a child would look at her system of values to predict the values of her contemporaries with whom she may interact a parent may thus choose to instil prosocial values into his child in order to signal to her that others can generally be trusted this implies that parents may optimally decide to endow their children with values that stand in contrast with maximization of material welfare even if their children s material welfare is all they care about jel codes d64 d82 h41 z13

job exit behavior of older men a dynamic programming model of job exit behavior and retirement is constructed and estimated using the method of simulated moments the model and estimation method allow for both unobserved individual effects and unobserved job specific match effects the model is estimated using two different assumptions about individual discount factors first a static model with the discount factor equal to zero is estimated then a dynamic model with the discount factor equal to 95 is estimated in both models it is found that bad health age and lack of education increase the probability of retirement the dynamic model performs better than the static model and has different implications for retirement behavior the job specific effects are an important source of unobserved heterogeneity copyright 1991 by the econometric society

the effect of pension design on employer costs and employee retirement choices evidence from oregon abstract we use administrative data from oregon s public employees retirement system pers to study the effect of pension design on employer costs and employee retirement timing decisions during our 1990 2003 sample period pers calculates each member s retirement benefit using up to three different formulas defined benefit db defined contribution dc and a combination of db and dc and pers pays the maximum benefit for which the member is eligible we show that this maximum benefit calculation results in average ex post retirement benefits that are 54 higher than if they had been calculated using only the db formula and that employees receiving dc benefits are significantly more likely than employees receiving db benefits to retire before the plan s normal retirement age monte carlo simulations verify that the higher costs could have been predicted at the start of our sample period exploiting exogenous plan changes we show that employees respond to within year variation in their retirement incentives and consistent with peer effects that they respond more strongly to these incentives when more of their coworkers face similar incentives finally consistent with the emerging literature on financial mistakes by households we show that a small but noteworthy fraction of retirees would have benefited from shifting their retirements by as little as one month

cognitive constraints on valuing annuities this paper documents consumers difficulty valuing life annuities using a purpose built experiment in the american life panel we show that the prices at which people are willing to buy annuities are substantially below the prices at which they are willing to sell them we also find that buy values are negatively correlated with sell values and that the sell buy valuation spread is negatively correlated with cognition this spread is larger for those with less education weaker numerical abilities and lower levels of financial literacy our evidence contributes to the emerging literature on heterogeneity in financial decision making abilities particularly regarding retirement payouts jel d14 d91 g11 h55

the econometrics of kinked budget constraints in the last several years a branch of applied econometrics has developed which is devoted to the development of techniques for the estimation of demand and other functions when the budget constraint is piecewise linear or kinky that is when the constraint consists of a number of segments joined together at kink points such constraints most frequently arise from government tax and transfer programs for example the federal income tax imposes a piecewise linear schedule by the use of constant marginal tax rates within brackets a problem analyzed by hausman 1981 the payroll tax in the social security system likewise generates a kinked schedule inasmuch as the marginal tax rate on earnings is zero above a certain earnings maximum federal and state transfer programs for the poor result in piecewise linear constraints because transfer benefits are taxed in the sense of a negative income tax as income rises and because that tax rate falls to zero at the kink point where an individual or family loses eligibility for the benefit altogether many government transfer programs impose additional nonlinearities by altering this tax rate by discrete amounts over the range of positive benefits as well but kinked constraints sometimes arise in nongovernment contexts a well known example being the block pricing schedule commonly set by utilities and volume discounting in general kinked budget constraints create two difficulties that have several interesting facets one difficulty is that changes in tax and transfer schedules can have unexpected effects that can be exactly the opposite in sign to those expected from economic theory examples of this phenomenon are given below the second difficulty that with which this paper is mostly concerned relates to the implications of kinked budget

financial incentives and retirement evidence from federal civil service workers we examine the retirement behavior of federal civil service workers employed by the department of defense these workers provide an interesting population for studying retirement because they face relatively simple financial incentives high quality administrative data are available and they are not covered by the social security system we find that these workers respond to their financial incentives in a similar manner to what others have found when analyzing much different retirement systems we also find no evidence of excess retirement at key ages of the social security system which does not support the existence of societal wide norms regarding retirement

harvest reporting timely information and incentives for technology adoption natural resource managers typically adopt precautionary quota buffers to account for scientific and management uncertainty such buffers ensure compliance with harvest targets up to a confidence level set by the manager but represent foregone profits and create incentives for firms voluntary investment in the provision of information that lessens the regulator s uncertainty this paper characterizes conditions under which the fishing industry would willingly upgrade its reporting technology to provide accurate and timely catch data wireless technologies currently available to harvesters make the provision of real time information feasible and affordable industry s incentives critically depend on the manager s expected choice of effort restrictions under the alternative technologies upgrading is attractive if the new distribution of reporting error shifts probability mass away from large errors so that the quantile at the confidence level is reduced first order stochastic dominance by the distribution under the baseline technology is a sufficient condition evidence from the maryland blue crab accountability pilot program an industry led initiative that tested the feasibility of adopting e logbooks illustrates the results real time availability of accurate catch information under electronic reporting would translate into in season adjustments of the manager s controls that could increase the industry s total harvest

an experimental analysis of optimal renewable resource management the fishery this paper experimentally studies the extraction decisions of a sole owner in a fishery the population dynamics of which behave according to the standard deterministic logistic growth model four treatments were implemented which differed in the level of information supplied to the subjects compared to the theoretic benchmark the data reveal that efficiency losses increase as the information on population dynamics and stock size deteriorates three common patterns of behaviour are identified the distribution of these patterns is significantly affected by the informational setting

new evidence on pensions social security and the timing of retirement using a unique dataset that links the economic and demographic information of households with the details of their pension formulas i estimate the combined effect of social security and pension benefits on the probability of retirement in a cross section of the population near retirement age the accrual rate of retirement wealth is shown to be a significant determinant of the probability of retirement simulations of extensions in pension coverage comparable to those that occurred in the early postwar period can account for one fourth of the contemporaneous decline in labor force participation rates 1998 elsevier science s a all rights reserved

health insurance availability and the retirement decision because individuals aged 55 64 face large and uncertain medical expenditures without the guarantee of public insurance coverage provided by medicare the availability of post retirement health insurance could be an important determinant in the retirement decisions of this group we investigate the effect of health insurance on retirement by focusing on state and federal continuation of coverage mandates which grant the retiree the right to continue purchasing health insurance through a previous employer for a specified number of months after leaving the firm we exploit variation in the timing and generosity of these laws to identify the effect of the availability of continuation coverage on retirement decisions using data on 55 64 year old males from the current population survey and the survey of income and program participation we find a sizeable and significant effect of continuation coverage on retirement one year of mandated continuation benefits raises retirement rates by 20 the effect appears to be uniform at all ages rather that larger near the age of medicare eligibility there is also a large increase in the insurance coverage of individuals who would have retired in the absence of continuation benefits our findings have important implications for policies which change the insurance coverage of early retirees such as national health insurance this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was b this abstract was borrowed from another version of this item

did soviet elderly employment respond to financial incentives evidence from pension reforms abstract this study answers the open question of whether workers respond to financial incentives in a command economy to do this i evaluate pension reforms in soviet russia in 1964 and 1969 that allowed pensioners to receive a greater share of their pensions if they worked resulting in a progressive elimination of benefit reduction rates variation in group eligibility and variation in benefit reduction rates in eastern and western regions allow for the use of several difference in differences frameworks i collect and digitize novel data from the soviet archives on pensioner employment constructing the first database of the soviet old age labor market i find that soviet pensioners are responsive to financial incentives by 1969 after the benefit reduction rate fell from an average of 47 8 to 24 1 pensioner employment rates rose by 5 7 percentage points representing a 47 increase finally i provide illustrative estimates of the employment elasticity with respect to the average net of tax rate that range from 0 6 to 1 4

do changes in pension incentives affect retirement a longitudinal study of subjective retirement expectations this paper investigates the responsiveness of individuals retirement decisions to forward looking measures of pension accumulations in contrast to previous research we use within person variation in retirement incentives and are able to control for unobserved heterogeneity in tastes for retirement by studying a panel of subjective retirement expectations we confirm that individuals do respond as expected to pension incentives even when we control for individual fixed effects however the magnitude of these responses differs when estimated from models based on within person versus cross sectional variation the inclusion of fixed effects reduces the response by about half

the effect of social security on labor supply a cohort analysis of the notch generation this article uses aggregate birth year calendar year level data derived from the current population survey cps to estimate the effect of social security wealth on the labor supply of older men in the 1970s and 1980s the analysis focuses on measuring the impact of the 1977 amendments to the social security act which created a substantial unanticipated reduction in social security wealth for individuals born after 1916 this differential in benefits has become known as the benefit notch results indicate that labor supply continued to decline for the notch babies who received lower social security benefits than earlier cohorts

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

policy variation labor supply elasticities and a structural model of retirement this paper exploits a combination of policy variation from multiple pension reforms in austria and administrative data from the austrian social security database using the policy changes for identification we estimate social security wealth and accrual elasticities in individuals retirement decisions next we use these elasticities to estimate a dynamic programming model of retirement decisions finally we use the estimated model to examine the labor supply and welfare consequences of potential social security reforms

on uncertain renewable resource stocks optimal harvest policies and the value of stock surveys abstract annual harvest quotas are commonly employed in the management of renewable resource stocks commercial fisheries being a prime example such resource stocks often undergo quite significant natural fluctuations to which quotas must be adapted a further complication arises from the fact that estimates of stock abundance are often highly uncertain in this paper a bayesian approach is used to model optimal quota decisions for an uncertain fluctuating renewable resource stock

labor supply responses to marginal social security benefits evidence from discontinuities abstract a key question for social security reform is whether workers respond to the link on the margin between the social security taxes they pay and the social security benefits they will receive we estimate the effects of the marginal social security benefits that accrue with additional earnings on three measures of labor supply retirement age hours and labor earnings we develop a new approach to identifying these incentive effects by exploiting five provisions in the social security benefit rules that generate discontinuities in marginal benefits or non linearities in marginal benefits that converge to discontinuities as uncertainty about the future is resolved we find that individuals approaching retirement age 52 and older respond to the social security tax benefit link on the extensive margin of their labor supply decisions we estimate that a 10 increase in the net of tax share reduces the two year retirement hazard by a statistically significant 2 0 percentage points from a base rate of 15 the evidence with regard to labor supply responses on the intensive margin is more mixed we estimate that the elasticity of hours with respect to the net of tax share is 0 42 and statistically significant but we do not find a statistically significant earnings elasticity though we lack statistical power to estimate results within subsamples precisely the retirement response is driven mostly by the female subsample while the hours response comes from the male subsample

moral hazard vs liquidity and optimal unemployment insurance this paper presents new evidence on why unemployment insurance ui benefits affect search behavior and develops a simple method of calculating the welfare gains from ui using this evidence i show that 60 percent of the increase in unemployment durations caused by ui benefits is due to a liquidity effect rather than distortions on marginal incentives to search moral hazard by combining two empirical strategies first i find that increases in benefits have much larger effects on durations for liquidity constrained households second lump sum severance payments increase durations substantially among constrained households i derive a formula for the optimal benefit level that depends only on the reduced form liquidity and moral hazard elasticities the formula implies that the optimal ui benefit level exceeds 50 percent of the wage the exact identification approach to welfare analysis proposed here yields robust optimal policy results because it does not require structural estimation of primitives

the role of information for retirement behavior evidence based on the stepwise introduction of the social security statement abstract in 1995 the social security administration started sending out the annual social security statement it contains information about the worker s estimated benefits at the ages 62 65 and 70 i use this unique natural experiment to analyze the retirement and claiming decision making first i find that despite the previous availability of information the statement has a significant impact on workers knowledge about their benefits these findings are consistent with a model where workers need to gather costly information in order to improve their retirement decision second i use this exogenous variation in knowledge to analyze the optimality of workers decisions several findings suggest that workers do not change their retirement behavior i workers do not change their expected age of retirement after receiving the statement ii monthly claiming patterns do not show any change after the introduction of the social security statement iii workers do not become more sensitive to social security incentives after receiving the statement more research is needed to establish whether workers are already behaving optimally but the information contained in the statement is not sufficient to improve their retirement behavior

valuation optimal asset allocation and retirement incentives of pension plans we provide a framework in which we link the valuation and asset allocation policies of defined benefits plans with the lifetime marginal productivity schedule of the worker and the pension plan formula in turn we examine the retirement policies that are implied by the primitives of the model and the value of pension obligations our model provides an explicit valuation formula for a stylized defined benefits plan the optimal asset allocation policies consist of the replicating portfolio of the pension liabilities and the growth optimum portfolio independent of the pension liabilities we show that the worker will retire when the ratio of pension benefits to current wages reaches a critical value which depends on the parameters of the pension plan and the discount rate using numerical techniques we analyze the feedback effect of retirement policies on the valuation of plans and on the asset allocation decisions article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

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

the effects of health insurance and self insurance on retirement behavior this paper provides an empirical analysis of the effects of employer provided health insurance medicare and social security on retirement behavior using data from the health and retirement study we estimate a dynamic programming model of retirement that accounts for both saving and uncertain medical expenses our results suggest that medicare is important for understanding retirement behavior and that uncertainty and saving are both important for understanding the labor supply responses to medicare half the value placed by a typical worker on his employer provided health insurance is the value of reduced medical expense risk raising the medicare eligibility age from 65 to 67 leads individuals to work an additional 0 074 years over ages 60 69 in comparison eliminating 2 years worth of social security benefits increases years of work by 0 076 years

income and substitution effects of a disability insurance reform abstract disability insurance di systems are widely criticized for their inherent work disincentives this paper evaluates the effects of a swiss di reform that aims to lower di benefits for a group of existing di beneficiaries and introduces an additional level to the di benefit schedule the reform has only modest effects on earnings and employment but increases the disability degree of those threatened by a di benefit decline we estimate bounds on the income and substitution effects by employing the principal stratification framework the income effect is quantitatively important whereas the substitution effect is smaller and has bounds that include zero the evidence suggests that caseworkers helped the insured with low labor market attachment to maintain a full di benefit

distinguishing income from substitution effects in disability insurance a set of studies conducted over the last 15 years has produced a near consensus that the social security disability insurance system ssdi has substantial disincentive effects on the labor supply of near elderly males diminishing labor force participation increasing the sensitivity of labor force exit decisions to adverse economic shocks and encouraging those nearing retirement to claim disability benefits and subsequently transfer into the social security retirement program yet efforts by the social security administration ssa to encourage labor supply among the disabled by removing the work disincentives built into ssdi have been almost entirely unsuccessful most notably in 1999 congress authorized the ticket to work program which provides an array of inducements for current ssdi beneficiaries to take up employment including permitting a trial work period of up to nine months providing 7 75 years of ongoing medicare eligibility following return to work and providing three years of automatic benefit reinstatement when claimants workplace earnings fall below a threshold level each of these steps reduces the implicit tax placed on labor supply by the ssdi program despite these lures fewer than 1 400 0 01 percent of the 12 2 million tickets issued to date have led to successful workforce integration autor and duggan 2006

the response of employees to severance incentives the university of california s faculty 1991 94 in response to huge budgetary shortfalls in the early 1990s the university of california offered its older and longer service employees financial inducements to leave this paper analyzes the responses of uc s faculty to three waves of buyout incentives it is estimated that an individual presented with 10 percent higher severance benefits has a 7 8 percent higher probability of quitting however quit probabilities are very difficult to forecast with accuracy this casts doubt on arguments that maintain that buyouts are superior to employer initiated layoffs as a mechanism to effect large employment changes

the econometrics of nonlinear budget sets traditional empirical analysis of consumer demand has usually made the assumption of linear budget sets that is the consumer is assumed to purchase any desired quantity at a constant price subject to a budget constraint the major exception to this framework is the analysis of demand when some goods are rationed 2 in the rationed case the price is constant up to a quantity limit in contrast to the rationed case here i consider the situation where the price varies with the amount of the good purchased empirical situations with nonconstant prices come readily to mind and of course they have received much recent attention from theorists since mirrlees 44 paper on optimal nonlinear taxation the following examples are meant to give a partial listing of cases when nonlinear budget sets occur i electricity prices many electric utilities engage in declining block pricing that is the marginal price of successive kwh s of electricity decrease at a given number of points determined by total demand thus the budget set is piecewise linear houthakker 36 was the first to propose an approach to this problem taylor 51 analyzes the problem at length and hausman kinnucin and mcfadden 31 use an instrumental variables estimator to provide consistent estimates of the demand function

retirement and consumption in a life cycle model consumption expenditure declines sharply at the time of retirement for many households but the majority maintain a smooth consumption path a simple life cycle model with uncertainty about the time of retirement can account for this pattern a richer version of the model is calibrated to data from the health and retirement study hrs the median change in consumption expenditure at retirement generated by the model is zero while the mean is negative matching the hrs data however the magnitude of the drop in consumption among households that experience a decline is too small in the model compared to the data

network effects and welfare cultures we empirically examine the role of social networks in welfare participation using data on language spoken at home to better infer networks within an area our empirical strategy asks whether being surrounded by others who speak the same language increases welfare use more for those from high welfare using language groups this methodology allows us to include local area and language group fixed effects and to control for the direct effect of being surrounded by one s language group these controls eliminate many of the problems in previous studies the results strongly confirm the importance of networks in welfare participation

the role of information and social interactions in retirement plan decisions evidence from a randomized experiment this paper analyzes a randomized experiment to shed light on the role of information and social interactions in employees decisions to enroll in a tax deferred account tda retirement plan within a large university the experiment encouraged a random sample of employees in a subset of departments to attend a benee ts information fair organized by the university by promising a monetary reward for attendance the experiment multiplied by more than e ve the attendance rate of these treated individuals relative to controls and tripled that of untreated individuals within departments where some individuals were treated tda enrollment e ve and eleven months after the fair was signie cantly higher in departments where some individuals were treated than in departments where nobody was treated however the effect on tda enrollment is almost as large for individuals in treated departments who did not receive the encouragement as for those who did we provide three interpretations differential treatment effects social network effects and motivational reward effects to account for these results

future social security entitlements and the retirement decision abstract a critical question for social security policy is how program incentives affect retirement behavior we use the health and retirement survey hrs to examine the impact of social security incentives on male retirement we implement forward looking models whereby individuals consider the incentives to work in all future years we find that forward looking incentive measures for social security are significant determinants of retirement we also find that private pension incentives have roughly similar effects our findings suggest that social security policies that increase the incentives to work at older ages can significantly reduce the labor force exit rate of older workers

what you don t know can t help you pension knowledge and retirement decision making abstract this paper provides an answer to an important empirical puzzle in the retirement literature while most people know little about their own pension plans retirement behavior is strongly affected by pension incentives we combine administrative and self reported pension data to measure the retirement response to actual and perceived financial incentives and document an important role for self reported pension data in determining retirement behavior well informed individuals are far more responsive to pension incentives than the average individual ill informed individuals seem to respond systematically to their own misperceptions of pension incentives

models of labour services and estimates of total factor productivity this article examines the manner in which labour services are modelled in the aggregate production function concentrating on the relationship between numbers employed and average hours worked it argues that numbers employed and hours worked are not perfect substitutes and that conventional estimates of total factor productivity which by using total hours worked as the measure of labour services assume they are perfect substitutes will be biased when there are marked changes in average hours worked the relevance of the theoretical argument is illustrated using data for the united states and the united kingdom

uncertain measurements of renewable resources approximations harvesting policies and value of accuracy abstract this paper deals with the management of renewable resources subject to measurement error the method stochastic optimization in policy space sops allows for more general solutions to problems that are not lq than earlier attempts measurement errors are found to be more important for quota policies than natural stochastic variation with little error filtering in time or in policy space is important with considerable error caution becomes important various approximations are compared policies based simply on historical measurements are found to give higher expected values than policies based on advanced kalman filter estimates values of measurement accuracy are estimated

the effects of health wealth and wages on labour supply and retirement behaviour this paper estimates a life cycle model of labour supply retirement and savings behaviour in which future health status and wages are uncertain individuals face a fixed cost of work and cannot borrow against future labour pension or social security income the method of simulated moments is used to match the life cycle profiles of labour force participation hours worked and assets that are estimated from the data to those that are generated by the model the model establishes that the tax structure of the social security system and pensions are key determinants of the high observed job exit rates at ages 62 and 65 removing the tax wedge embedded in the social security earnings test for individuals aged 65 and older would delay job exit by almost one year by contrast social security benefit levels health and borrowing constraints are less important determinants of job exit at older ages for example reducing social security benefits by 20 would cause workers to delay exit from the labour force by only three months

adjustment costs firm responses and micro vs macro labor supply elasticities evidence from danish tax records we show that the effects of taxes on labor supply are shaped by interactions between adjustment costs for workers and hours constraints set by firms we develop a model in which firms post job offers characterized by an hours requirement and workers pay search costs to find jobs we present evidence supporting three predictions of this model by analyzing bunching at kinks using danish tax records first larger kinks generate larger taxable income elasticities second kinks that apply to a larger group of workers generate larger elasticities third the distribution of job offers is tailored to match workers aggregate tax preferences in equilibrium our results suggest that macro elasticities may be substantially larger than the estimates obtained using standard microeconometric methods

how social security and medicare affect retirement behavior in a world of incomplete markets this paper provides an empirical analysis of how the u s social security and medicare insurance system affect the labor supply of older males in the presence of incomplete markets for loans annuities and health insurance we estimate a detailed dynamic programming dp model of the joint labor supply and social security acceptance decision focusing on a sample of males in the low to middle income brackets whose only pension is social security the dp model delivers a rich set of predictions about the dynamics of retirement behavior and comparisons of actual vs predicted behavior show that the dp model is able to account for wide variety of phenomena observed in the data including the pronounced peaks in the distribution of retirement ages at 62 and 65 the ages of early and normal eligibility for social security benefits respectively we identify a significant fraction of health insurance constrained individuals who have no form of retiree health insurance other than medicare and who can only obtain fairly priced private health insurance via their employer s group health plan the combination of significant individual risk aversion and a long tailed pareto distribution of health care expenditures implies that there is a significant security value for these individuals to remain employed until they are eligible for medicare coverage at age 65 overall our model suggests that a number of heretofore puzzling aspects of retirement behavior can be viewed as artifacts of particular details of the social security rules whose incentive effects are especially strong for lower income individuals and those who do not have access to fairly priced loans annuities and health insurance

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

labor supply effects of the recent social security benefit cuts empirical estimates using cohort discontinuities abstract in response to a crisis in social security financing two decades ago congress implemented an increase in the normal retirement age nra of 2 months per year for cohorts born in 1938 and after these cohorts began reaching retirement age in 2000 this paper studies the effects of these benefit cuts on recent retirement behavior the evidence suggests that the mean retirement age of the affected cohorts has increased by about half as much as the increase in the nra if older workers continue to increase their labor supply in the same way there might be important implications for the estimates of social security trust fund exhaustion that have played such a major role in recent discussions of social security reform

expenditure response to health insurance policies evidence from kinks in rural china abstract this paper utilizes administrative data to analyze expenditure responses to the health insurance policy in rural china and clear visual evidence of bunching is observed at the kink point a static response model with optimization frictions estimates that a complete elimination of the reimbursement would cause the total expenditure per visit to decrease by 34 5 and approximately one third of the studied population makes decisions with errors heterogeneous expenditure responses and optimization frictions are observed across demographic groups cost benefit and counterfactual analyses indicate that the current policy generates the greatest welfare gains

optimal growth with unobservable resources and learning abstract this paper examines the problem of choosing optimal resource consumption from an imperfectly observable aggregate capital wealth or resource stock which the decision maker learns about over time learning is complicated by the fact that the planner receives information about an object the true resource stock which is a moving target under the assumption that the utility of zero consumption is we show that the optimal policy follows a completely deterministic cautious or minmax policy that assumes the worst in each period and optimizes against that when this model is compared to a model with completely observable wealth levels the following insights are obtained 1 there is over saving 2 investment and output processes are more volatile than consumption and 3 regressions underestimate the risk aversion of agents information about the wealth or stock level is only valuable if it alters the support of the agent s beliefs thus information may be statistically informative yet economically valueless if information changes the support of the agent s beliefs then the optimal solution features an endogenous resource discovery process

worker retirement responses to pension incentives do they respond to pension wealth abstract pension enhancements generate pension wealth spikes at the eligibility milestones i analyze two major enhancements that generated different gains in pension wealth for eligible workers the responsiveness of retirement behavior to these enhancements depends on how well workers understand their pension incentives to test the retirement response to pension wealth i use administrative data from missouri teachers and leverage variation in enhancement impacts on teacher pension wealth owing to differences in teachers entering ages i find that retirements respond strongly to pension enhancements but the strength of the response does not align with their pecuniary value my findings contribute to a growing body of research showing that workers have imperfect knowledge of their pension benefits and they use imprecise information to make retirement timing decisions

a structural retirement model the life cycle model analyzed here constrains most work on the main job to be full time partial retirement entails a wage reduction and frequently a job change maximum likelihood estimates of utility function parameters are designed to incorporate information on the age of leaving full time work and the age of full retirement the model closely tracks retirement behavior including peaks in retirement activity at 62 and 65 the paper explores the relation of these peaks to nonlinearities in the budget constraint created by various retirement programs policy analyses based on this and on earlier models with simpler structures are compared the retirement choice is one of the more prominent manifestations of life cycle behavior the decision is the result of an interplay between an individual s preferences and a set of incentives which change in complicated ways as the individual progresses through his or her late 50 s and 60 s the purpose of this study is to formulate and estimate a structural model which incorporates in a fundamental way this interplay between lifetime preferences and incentives and to illustrate how such a model may be used to investigate retirement behavior a structural model of this type is essential for analyzing potential policy changes which can be expected to affect incentives in varying ways over a number of years in the life cycle the current study incorporates two structural features which have frequently been omitted from previous studies first the model requires that an individual who wishes to reduce work effort below full time must accept a reduced hourly wage rate in order to do so this reflects empirical evidence from micro data sets which indicates that around one third of older individuals engage in part time work at one time or another and that regardless of whether or not these older workers change jobs to obtain part time work they usually take wage cuts as compared to their previous full time work 2 the fact that an individual is willing to accept a lower wage rate in return for the opportunity to work fewer than full time hours contains important information about the preferences of the

the labor supply effects of the social security earnings test the social security earnings test taxes away benefits at a 33 50 rate once earnings pass a threshold amount i investigate the response to three past changes in the earnings test rules each applying to some age groups and not others i find that beneficiaries bunch in substantial numbers just below the earnings threshold and the bunching shifts when the earnings test rules change these shifts in the budget constraint are incorporated into an econometric model to identify income and substitution effects the estimation yields significant elasticities that suggest considerable deadweight loss suffered by working beneficiaries

pension spiking free riding and the effects of pension reform on teachers earnings in many states local school districts are responsible for setting the earnings that determines the size of pensions but are not required to make contributions to cover the resulting state pension fund liabilities in this paper i document evidence that this intergovernmental incentive inherent in public sector defined benefit pension systems distorts the amount and timing of income for public school teachers i use the introduction of a policy that required experience rating on earnings increases above a certain limit in a differences in differences framework to identify whether districts are willing to pay the full costs of their earnings promises because of the design of the policy overall earnings of teachers near retirement did not change instead districts that previously provided one time pay increases shifted to smaller increments spread out over several years in addition some districts that did not practice pension spiking prior to the reform appear to begin providing payments up to the new lower limit perhaps due to increased salience of the fiscal incentive therefore the policy was ineffective at decreasing pension costs

discounting climate and sustainability climate policy recommendations differ widely because of disagreements over what discount rates to use disagreement reduces the impact of economic models and signals a need for improved methodology the problem is related to the choice of intergenerational welfare functions a first questionnaire finds that the standard welfare function swf fails to capture people s dislike of overshooting and fluctuating consumption paths a second questionnaire reveals that when very long term sustainability of well being is threatened people s implicit discount rates resemble the low estimates used by the stern review an alternative welfare function awf reflecting consumption growth can potentially capture the preference structure revealed in both questionnaires this makes the awf an interesting candidate when searching for policies for sustainable development under uncertainty importantly the questionnaires demonstrate that people are able to choose among policies by inspecting time graphs of policy consequences thus it is possible to circumvent the complexities and disagreements introduced by welfare functions and discounting

total factor productivity an unobserved components approach this work examines the presence of unobserved components in the time series of total factor productivity tfp which is an idea central to modern macroeconomics the main approaches in both the study of economic growth and the study of business cycles rely on certain properties of the different components of the time series of tfp in the study of economic growth the neoclassical growth model explains growth in terms of technical progress as measured by the secular component of tfp while in the study of business cycles the real business cycle approach explains short run fluctuations in the economy as determined by temporary movements in the production function which are reflected by the cyclical component of the time series of the same variable the econometric methodology employed in the estimation of these different components is the structural time series approach developed by harvey 1989 harvey and shephard 1993 and others an application to the time series of tfp for the 1948 2002 us priva

active vs passive decisions and crowd out in retirement savings accounts evidence from denmark using 41 million observations on savings for the population of denmark we show that the effects of retirement savings policies on wealth accumulation depend on whether they change savings rates by active or passive choice subsidies for retirement accounts which rely on individuals to take an action to raise savings primarily induce individuals to shift assets from taxable accounts to retirement accounts we estimate that each 1 of government expenditure on subsidies increases total saving by only 1 cent in contrast policies that raise retirement contributions if individuals take no action such as automatic employer contributions to retirement accounts increase wealth accumulation substantially we estimate that approximately 15 of individuals are active savers who respond to tax subsidies primarily by shifting assets across accounts 85 of individuals are passive savers who are unresponsive to subsidies but are instead heavily influenced by automatic contributions made on their behalf active savers tend to be wealthier and more financially sophisticated we conclude that automatic contributions are more effective at increasing savings rates than subsidies for three reasons i subsidies induce relatively few individuals to respond ii they generate substantial crowd out conditional on response and iii they do not increase the savings of passive individuals who are least prepared for retirement jel codes h2 h3

from cradle to grave how to loot a 401 k plan abstract the regulations governing asset distributions from many retirement plans give participants the option to time retirement or rollovers from the plan strategically they possess a long lived put option whose exercise price resets periodically to the current value of the assets in the plan i derive a recursive closed form valuation formula for the option and develop a numerical algorithm for implementing the result i find that for reasonable assumptions about volatility and life expectancy the option s value may approach 40 of the value of the assets in the plan financed entirely by those still contributing this wealth transfer can however be easily avoided by making a simple change to the current regulations governing valuation and payout of these retirement plans

100 bills on the sidewalk suboptimal investment in 401 k plans we identify employees at seven companies whose 401 k investment choices are dominated because they are contributing less than the employer matching contribution threshold despite being vested in their match and being able to make penalty free 401 k withdrawals for any reason because they are older than 59 at the average firm 36 of match eligible employees over 59 forego arbitrage profits that average 1 6 of their annual pay or 507 a survey educating employees about the free lunch they are foregoing raised contribution rates by a statistically insignificant 0 67 percent of income among those completing the survey

the effect of age targeted tax credits on labor force participation of older workers abstract i analyze the effect of income tax policy changes on labor force participation of older workers i exploit two age targeted policy initiatives to promote work at older ages simultaneously implemented in sweden in 2007 an earned income tax credit and a payroll tax credit for workers above age 65 using an age based discontinuity in eligibility criteria i conduct a difference in differences analysis with the reform as an instrument for the net of tax rate i find a participation elasticity with respect to the net of participation tax rate of about 0 22 in the year following the 65th birthday for individuals who were working four years earlier

employment and retirement following a late career job loss the frequency of job loss among workers in late career has risen disproportionately in recent years the effects of job loss on these workers are potentially severe their earnings capacity savings and retirement expectations are likely to be dramatically affected and they may take substantially longer to be re employed however despite these reasons for heightened concern relatively little is known about the economic consequences of late career job loss among recent cohorts of workers this paper presents findings from an ongoing research project using the health and retirement study that focuses on the economic impacts of late career job loss on employment and retirement patterns as well as on earnings and assets this abstract was borrowed from another version of this item

social security unanticipated benefit increases and the timing of retirement between 1969 and 1972 real u s social security retirement benefits rose by 20 the rise was unanticipated and followed over 15 years of relatively constant real benefits this paper proposes a model of retirement behaviour in which workers respond differently although in a theoretically consistent manner to the anticipated and unanticipated components of the social security benefit they can receive upon retirement the retirement age decision in the presence of unanticipated benefit changes is shown to be a special case of utility maximization under a nonlinear budget constraint the model is estimated using the longitudinal retirement history survey between 1969 and 1973 real social security benefits for u s workers with fixed earnings histories were raised by more than 20 these increases were the first significant increases in social security since the early 1950 s at the same time that retirement benefits were rising the trend toward early retirement among older american men accelerated in the period from 1965 to 1970 the labour force participation rate of men aged 55 to 64 fell 1 6 percentage points from 84x6 to 83 0 but in the five years after 1970 the rate fell an additional 7 4 points to 75 6 the participation rate of men over 65 fell by 1 1 points in the five years after 1965 but by 5 2 points during the mid 1970 s 1 not surprisingly a large share of this labour force decline has been attributed to the effects of the social security increases enacted in 1969 and 1972 the purpose of this paper is to determine the precise effect of the unanticipated benefit increases on the timing of retirement the effect of social security on the age at retirement has been the subject of lively debate in recent years the literature has been reviewed in two recent papers by mitchell and fields 1982 and hurd 1983 who reach nearly opposite conclusions about the lessons that can be drawn from past empirical research mitchell and fields find that no definite judgment can be reached about the effects of social security on retirement while hurd argues that more careful studies have all found a significant and meaningful effect of social security on early retirement certainly the earlier studies by boskin 1977 and boskin and hurd 1978 found very large social security effects with boskin concluding that the social security system has been the major factor in the explosion in earlier retirement boskin 1977 p 1 very recent studies by burkhauser and quinn 1983 burtless and moffitt 1984 diamond and hausman 1984 fields and mitchell 1984 and hausman and wise 1985 have found smaller social security effects however none of them dealt explicitly with the rapid rise in real benefits during the early 1970 s the approach taken in this paper differs significantly from that in the earlier research just cited the proposed econometric model takes full account of the nonlinear relationship between goods consumption and the age at retirement introduced by social security

car notches strategic automaker responses to fuel economy policy notches where small changes in behavior lead to large changes in a tax or subsidy gure prominently in many policies but have been rarely examined by economists in this paper we analyze a class of notches associated with policies aimed at improving vehicle fuel economy we provide several pieces of evidence showing that automakers respond to notches in fuel economy policy by precisely manipulating fuel economy ratings so as to just qualify for more favorable treatment we then describe the welfare consequences of this behavior and derive a welfare summary statistic applicable to many contexts
