strikes as a result of imperfect information this paper proposes a model of the bargaining process that recognizes that negotiators have only imperfect information at their command the author argues that the probability of a strike occurring will increase if one party bases its perception of the opponent s position on the same variables employed to form its own position when the opponent s position is in fact based on different variables strike probability is therefore assumed to be related to movements in variables of interest to only one side the model is tested on a sample of fourteen bargaining relationships drawn from the series wage chronology published by the bureau of labor statistics which details settlements between particular firms and unions over a period of about thirty years estimates of strike probability are derived from the maximum likelihood logit procedure the findings suggest that although both relative and absolute wage increases in a firm have a negative effect on strike frequency relative changes are more important

moral hazard adverse selection and health expenditures a semiparametric analysis theoretical models predict asymmetric information in health insurance markets may generate inefficient outcomes due to adverse selection and moral hazard however previous empirical research has found it difficult to disentangle adverse selection from moral hazard in health care consumption we propose a two step semiparametric estimation strategy to identify and estimate a canonical model of asymmetric information in health care markets with this method we can estimate a structural model of demand for health care we illustrate this method using a claims level data set with confidential information from a large self insured employer we find significant evidence of moral hazard and adverse selection

collective bargaining in the public sector the effect of legal structure on dispute costs and wages this paper examines the impact of collective bargaining legislation on dispute costs and wages using a panel of canadian public sector contracts the authors results suggest that policymakers designing collective bargaining legislation face a trade off between reducing dispute costs and increasing wages dispute costs are lower under compulsory arbitration than under the right to strike or when no collective bargaining legislation exists hence a switch to compulsory arbitration could potentially make both the union and the employer better off by reducing dispute costs however the authors find that wages are higher under compulsory arbitration than under other legal structures copyright 1991 by american economic association

strikes and holdouts in wage bargaining theory and data we develop a private information model of union contract negotiations in which disputes signal a firm s willingness to pay previous models have assumed that all labor disputes take the form of a strike yet a prominent feature of u s collective bargaining is the holdout negotiations often continue without a strike after the contract has expired production continues with workers paid according to the expired contract we analyze the union s decision to strike or hold out and highlight its importance to strike activity strikes are more likely to occur after a drop in the real wage or a decline in unemployment

collective bargaining firm size and pensions in canada abstract the following paper analyzes the provision of job related pensions in canada the empirical results indicate that both unions and firm size have significant effects on the distribution of pensions the significance of unions on the provision of pensions does decline as firm size increases

globesity the effects of globalization on obesity and caloric intake abstract we examine the effect of globalization in its economic and social dimensions on obesity and caloric intake namely the so called globesity hypothesis our results suggest a robust association between globalization and both obesity and caloric intake a one standard deviation increase in globalization is associated with a 23 8 percent increase in obese population and a 4 3 percent rise in calorie intake the effect remains statistically significant even after using an instrumental variable strategy to correct for some possible reverse causality and ommited variable bias a lagged structure and corrections for panel standard errors however we find that the primary driver of the globesity phenomenon is the social rather than the economic dimension of globalization and specifically the effect of changes in information flows and social proximity on obesity a one standard deviation increase in social globalization increased the percentage of obese population by 13 7 percent

unions and strikes with asymmetric information strikes seem to be a pareto inefficient outcome of bargaining between a union and a firm however this paper shows that strikes can be the outcome of rational behavior by both agents if the firm has more information than the union concerning the state of nature the union can use strikes as a way of gaining information the paper uses an asymmetric information model where the firm has information about the state i e profitability that the union does not know the schedule of wage offers by the union then depends on the probability that a given state will occur

cyclical fluctuations in strike activity using a set of data on contracts and strikes for the period 1970 81 the author distinguishes among the roles of aggregate business conditions labor market conditions and product market conditions in the determination of strike incidence and duration strike incidence is found to be highest in industries that are depressed relative to the rest of the economy but in regions with low unemployment this finding is consistent with the theory that the cost of a strike to a firm increases with the demand for its product and the cost of a strike to the union increases with unemployment another finding however is that strikes are longest in industries that are booming relative to the rest of the economy

home equity in retirement retired homeowners dissave more slowly than renters which suggests that homeownership affects retirees saving decisions we investigate empirically and theoretically the life cycle patterns of homeownership housing and nonhousing assets in retirement using an estimated structural model of saving and housing decisions we find first that homeowners dissave slowly because they prefer to stay in their house as long as possible but cannot easily borrow against it second the 1996 2006 housing boom significantly increased homeowners assets these channels are quantitatively significant without considering homeownership retirees net worth would be 28 44 lower depending on age

on the distribution and dynamics of health care costs using data from the health and retirement survey and the assets and health dynamics of the oldest old survey we estimate the stochastic process that determines both the distribution and dynamics of health care costs we find that the data generating process for log health costs is well represented as the sum of a white noise process and a highly persistent ar 1 process we also find that the innovations to this process can be modelled with a normal distribution that has been adjusted to capture the risk of catastrophic health care costs simulating this model we find that in any given year 0 1 of households receive a health cost shock with a present value of at least 125 000 copyright 2004 john wiley sons ltd

contracts and strikes in canada 1952 1988 between 1952 and 1979 labour canada collected data on something in excess of 5300 contracts an earlier subset of these data covering 19531973 was used in work by inter alia riddell 1979 1980 but in recent years they have not been widely studied the reason is perhaps that in the early 1960s while labour canada was still assembling what is usually referred to as the wage chronologies file work also began on the collection of contract data for what is known as the wage file this data collection which continues to the present day has generated what many view as an unparalleled source of detail about wage agreements and most analyses of canadian contracts focus on the wage file alone this short paper briefly describes some aspects of the preparation of both data sets for analysis including the incorporation of information on strikes when they occurred a longer version of this paper that is available from the author dwells in considerably more detail on these issues the other main focus of this paper is on some preliminary evidence from a combination of the two samples covering contracts from 1952 to 1988 specifically the combined sample reveals several insights into changes over time in strike behaviour and contract length in future papers it is planned to use an extended version of the data beyond 1988 to explore these and other issues for a period of over 40 years the paper is organized as follows section ii describes the two sets of contract data paying particular attention to the use of labour canada s work stoppage file to supplement the information on those contracts that were settled only after a strike section iii outlines one way of combining the contract data sets and reports on the changes over time in strike behaviour and contract duration thus revealed

analyzing the effects of insuring health risks on the trade off between short run insurance benefits vs long run incentive costs this paper constructs a dynamic model of health insurance to evaluate the short and long run effects of policies that prevent firms from conditioning wages on health conditions of their workers and that prevent health insurance companies from charging individuals with adverse health conditions higher insurance premia our study is motivated by recent us legislation that has tightened regulations on wage discrimination against workers with poorer health status americans with disability act of 2009 ada and ada amendments act of 2008 adaaa and that will prohibit health insurance companies from charging different premiums for workers of different health status starting in 2014 patient protection and affordable care act ppaca in the model a trade off arises between the static gains from better insurance against poor health induced by these policies and their adverse dynamic incentive effects on household efforts to lead a healthy life using household panel data from the psid we estimate and calibrate the model and then use it to evaluate the static and dynamic consequences of no wage discrimination and no prior conditions laws for the evolution of the cross sectional health and consumption distribution of a cohort of households as well as ex ante lifetime utility of a typical member of this cohort in our quantitative analysis we find that although a combination of both policies is effective in providing full consumption insurance period by period it is suboptimal to introduce both policies jointly since such policy innovation induces a more rapid deterioration of the cohort health distribution over time this is due to the fact that combination of both laws severely undermines the incentives to lead healthier lives the resulting negative effects on health outcomes in society more than offset the static gains from better consumption insurance so that expected discounted lifetime utility is lower under both policies relative to only implementing wage nondiscrimination legislation

wage bargaining with time varying threats we study wage bargaining in which the union is uncertain about the firm s willingness to pay and threat payoffs vary over time strike payoffs change as replacement workers are hired as strikers find temporary jobs and as inventories or strike funds run out we find that bargaining outcomes are substantially altered if threat payoffs vary if dispute costs increase in the long run then dispute durations are longer settlement rates are lower and wages decline more slowly during the short run and may even increase the settlement wage is largely determined from the long run threat rather than the short run threat

the use of replacement workers in union contract negotiations the u s experience 1980 1989 it is argued in many circles that a structural change occurred in u s collective bargaining in the 1980s strike incidence declined dispute incidence increased and the composition of disputes shifted away from strikes and toward holdouts we investigate the extent to which the hiring of replacement workers can account for these changes for a sample of over 300 major strikes since 1980 we estimate the likelihood of replacements being hired we find that the risk of replacement is lower for bargaining units with more experienced workers and declines during tight labor markets the composition of disputes shifts away from strikes as the predicted risk of replacement increases in addition the overall level of disputes increases as a result of the shift in the composition of disputes based on our estimates reducing the predicted replacement risk faced by bargaining units to the pre 1982 levels would have lead to a reduction in the dispute incidence by around 5 percentage points an increase in the fraction of disputes involving a strike by around 4 percentage points and an increase in the strike incidence by around 0 8 percentage points

the strategic bequest motive although recent research suggests that intergenerational transfers play an important role in aggregate capital accumulation our understanding of bequest motives remains incomplete we develop a simple model of strategic bequests in which a testator influences the decisions of his beneficiaries by holding wealth in bequeathable forms and by conditioning the division of bequests on the beneficiaries actions the model generates falsifiable empirical predictions that are inconsistent with other theories of intergenerational transfers we present econometric and other evidence that strongly suggests that bequests are often used as compensation for services rendered by beneficiaries

an empirical study of the adverse selection model of strikes problems with existing empirical studies of the asymmetric information theory of strikes are 1 industry level data are used as proxies for firm level variables 2 studies using firm level data potentially suffer from simultaneity bias and 3 one of the key predictions of the theory is not tested the present paper addresses these issues while estimating a probit model of strike incidence using data comprising 2 459 contracts from canadian industry for 1964 85 that are merged with firm specific data under a number of alternative specifications results support the main predictions of the asymmetric information theory of strikes

the spirit of capitalism and savings behavior abstract this paper presents a capitalist spirit model of savings by including wealth in the intertemporal utility function while this model includes the life cycle model and bequest model as two special cases it sheds light on why wealth holding has tended to increase with age why decumulation of wealth after retirement has not happened and why households with and without children have not shown significant differences in their savings behavior the capitalist spirit approach is especially useful for understanding savings by the rich and savings across countries and over time jel e21 b10

the incidence of medicare abstract the medicare program transfers nearly 300 billion annually from taxpayers to beneficiaries this paper considers the incidence of such transfers in the context of a life cycle model with uncertainty about future health care expenditures we find the distributional consequences of the medicare program are roughly neutral in dollar terms households living in high income neighborhoods pay more in taxes but they also receive more in benefits these dollar flows however ignore the insurance value of the medicare system given the incomplete insurance coverage of lower income elderly households prior to the medicare program the money metric benefits to lower income groups exceed the dollar flows suggesting that medicare redistributes more than a simple accounting exercise would suggest

is strike behavior cyclical we examine cyclicality of strike frequency and incidence using canadian data on strikes and contracts total strike frequency exhibits significant procyclicality to which within contract strikes contribute appreciably evidence is weaker for procyclical behavior of contract expiry strikes both in total and disaggregated by issue strike incidence is also procyclical particularly in manufacturing though the procyclicality here is confined to strikes over nonwage issues these results mirror those obtained by analyzing the frequency of strikes in the contract data industry specific cyclical variables positively affect strike incidence in manufacturing but region specific variables have no effect

inheritance and wealth inequality the case of the punjab abstract this study follows a wealth function approach to quantify the role of inheritance in wealth inequality in the region of punjab india using household data from the national sample survey 25th round the specification of the wealth function is fairly general it is used to test the hump shaped pattern of wealth age relationship and also to decompose the reported wealth holding of each sample household into inherited and accumulated components it is found that inheritance accounts for 53 38 and 24 13 percent of wealth inequality in the rural and urban sectors respectively some policy implications of our results are stated

expanding the life cycle model precautionary saving and public policy one of the key puzzles in understanding saving behavior is not so much why people save the title of this session but why people don t save according to the familiar life cycle model households should accumulate wealth to provide for their retirement consumption the surprising result from the data is the sizable fraction of the population who have accumulated so little even among those nearing retirement given that earnings will almost surely decline when households retire such behavior can imply poor living standards for the elderly some might interpret the low wealth accumulation as being evidence of myopia irrationality or a failure of households to enforce mental accounting richard thaler 1994 while others might view the low level of wealth accumulation as evidence of high individual rates of time preference determining the underlying causes of low wealth is crucial for public policies that seek to alleviate low aggregate saving rates in the united states as well as policies that seek to buttress the adequacy of financial resources for the elderly in this paper we outline what we believe to be the causes of why many people do not save we conclude by speculating about government policies that may be most effective at encouraging saving much of the research examining levels of consumption saving and wealth as well as their responsiveness to policy has been done using a life cycle model with the simplifying assumption of perfect certainty alan auerbach and laurence kotlikoff 1987 for example developed a model with 55 overlapping generations of individual lifecycle households each with empirically plausible age earnings profiles and utility parameters and used the model to address tax policy and demographic issues in a regime in which all households are identical within a generation and all generations know future earnings and interest rates more recently a line of inquiry has examined the effects of uncertainty on saving generally in the context of highly stylized models this research has shown that in these models uninsured earnings uncertainty can alter optimal saving behavior in a variety of important ways for a partial review of this precautionary saving literature see hubbard et al 1994 in two recent papers hubbard et al 1993 1994 we have combined these two strands of the literature by examining the implications of a life cycle model of consumption saving and wealth accumulation subject to what we think are the three most important sources of uninsured idiosyncratic risk facing households uncertainty about earnings medical expenses and length of life our intent has been to create a realistic model in which families live for many periods working for part of their lives and retiring later in life to parameterize the uncertainty facing families we estimate tdiscussants christopher carroll federal reserve board john b shoven stanford university laurence kotlikoff boston university

is there a retirement savings puzzle in this paper we ask whether households are saving enough for their retirement we use data on income expenditure and expenditure components to analyse patterns of behaviour at and around the time of retirement for successive date of birth cohorts we compare periods of unemployment to periods of retirement and separate expenditures into categories reflecting work related expenditures basic necessities and other goods we find that income typically falls by more at unemployment than retirement but the reverse is true for expenditure we observe falls in expenditure at retirement for all expenditure categories using a stochastic life cycle model including mortality rates we assess the anticipated impact of retirement on consumption against that of unemployment the inter relationship between goods and leisure explains a large part of the persistent fall in expenditure at retirement we argue that the only way in which the life cycle hypothesis could be reconciled with the remaining unanticipated dip in consumption would be with the systematic arrival of unexpected adverse information at the time of retirement

paradoxical effects of increasing the normal retirement age a prospective evaluation abstract a life cycle model that incorporates both disability insurance di and old age insurance oai is developed to study social security reforms and is compared to an alternative model without di the model with di predicts that increasing the normal retirement age nra causes a decrease in employment and an increase in di receipt and that the decrease of payroll tax revenue and the increase of di expenses combined offset about 40 of the decrease of oai expenses these paradoxical effects of increasing the nra are absent from the model without di i employ both models to search for reforms that will balance the government budget in an economy with an aging population which has the demographics for the year 2100 and find that the required change in tax and benefit rules differ substantially across the two models

uncertain medical expenses and precautionary saving near the end of the life cycle this paper introduces a dynamic structural model of household consumption decisions in which elderly families consider the effects of uncertain future medical expenses when deciding current levels of consumption the model with uncertain medical expenses implies a potentially important role for precautionary saving incentives to explain slow rates of dissaving among elderly americans during retirement rather than just simulating the stochastic dynamic model preference parameters are estimated using panel data on health wealth and expenditures for retired families the health uncertainty model predicts consumption levels closer to observed expenditures than a life cycle model with uncertain longevity however elderly families typically dissave their financial assets more slowly than even the baseline health uncertainty model predicts is optimal

the vp function a survey of the literature on vote and popularity functions after 25 years vp functions explain the support for the government at votes and polls by economic and political variables most studies analyze macro time series we also cover studies of individual voters socio economic groups and regional cross sections the theory starts from the responsibil ity hypothesis voters hold the government responsible for economic conditions it works in two party block systems but not else voters in most countries are found to be sociotropic egotropic voting also occurs voters myopia is well established voting is retrospective as expectations are static it costs the average government almost 2 of the vote to rule

pay as you go social security and the distribution of altruistic transfers this paper studies the impact of an unfunded social security system on the distribution of altruistic transfers in a framework where savings are due to both life cycle and random altruistic motivations we show that the effect of social security on the distribution of these transfers depends crucially on the strength of the bequest motive in explaining savings behaviour we measure this strength by the expected weight that individuals attach to the utility of future generations on the one hand if the bequest motive is strong then an increase in the social security tax raises the bequests left by altruistic parents on the other hand when the importance of altruism in motivating savings is sufficiently low the increase in the social security tax could result in a reduction of the bequests left by altruistic parents under some conditions on the attitude of individuals toward risk and on the relative returns associated with private saving and social security some implications concerning the transitional effects of introducing an unfunded social security scheme are also discussed

privatization and the british electorate microeconomic policies macroeconomic evaluations and party support despite much scholarly research on the link between macroeconomic evaluations and political behavior relatively little is known about the influence of government economic policy on this process margaret thatcher s recent sales of public assets privatization in britain provide a unique opportunity to examine the link between microeconomic activity measured by privatization macroeconomic evaluations and voting by applying multivariate analysis to data collected during the 1983 and 1987 general elections we show that privatization measured by share purchases and council house ownership stimulates positive judgments about the country s economy however the effect of privatization on the vote is almost entirely indirect via these retrospective judgments about the economy while privatization has undoubtedly benefited the conservatives electorally the evidence on council house purchases suggests that the impact may be temporary

the vp function revisited a survey of the literature on vote and popularity functions after over 40 years nannestad and paldam public choice 79 213 245 1994 published herein an extremely influential review of the literature linking economics and elections what they called the vp functions in that work they offered a number of conclusions in proposition form about the state of the evidence in this field we present the key ones 16 in all and assess the extent to which they continue to hold in light of the new evidence about what has come to be known as economic voting as shall be shown nannestad and paldam were prescient in their early establishment of many of the principal results explaining how the economy moves the vote choice

estimating strike effects in a general model of prices and quantities estimates of the effect of strikes on the production price and purchases of north american automobiles are provided over the period 1966 79 the estimates are based on a model that reflects the decisions of both consumers and producers and that captures important intertemporal adjustments before during and after the strike to allow for inventory buildup in anticipation of the strike as well as inventory depletion during the strike and replacement afterward the results generally indicated that both consumers and producers rationally responded to the expected and the actual event of the strike through a variety of related intertemporal adjustments and while the initial effects are in some instances quite pronounced the long run effects are usually minimal

logit estimates of strike incidence from canadian contract data logit estimates of strike incidence are made based on a unique and comprehensive data set of 2 437 collective agreements the appropriate level of aggregation since that is where bargaining occurs the results are interpreted through a theoretical framework emphasizing that strikes are more likely when the joint costs of using the strike mechanism are low relative to the cost of alternative mechanisms for achieving the same purposes such functions of strikes are to generate information elicit truth telling establish reputations provide catharsis and solve intraorganizational conflict

health and mortality delta assessing the welfare cost of household insurance choice we develop a pair of risk measures health and mortality delta for the universe of life and health insurance products a life cycle model of insurance choice simplifies to replicating the optimal health and mortality delta through a portfolio of insurance products we estimate the model to explain the observed variation in health and mortality delta implied by the ownership of life insurance annuities including private pensions and long term care insurance in the health and retirement study for the median household aged 51 to 57 the lifetime welfare cost of market incompleteness and suboptimal choice is 3 2 of total wealth

explaining the decline of the u s saving rate the role of health expenditure between 1980 and 2007 the u s personal saving rate declined from 11 percent to 3 percent in this paper we provide evidence that most of the decline can be explained by rising health expenditures we rst employ reduced form methods and exogenous variation in medical expenses generated by fda drug approvals to document that a 1 percentage point increase in health expenditure generated a decline in the saving rate that is between 0 73 and 0 89 percentage points using this result we calculate that the rise in health expenditure explains about 90 percent of the drop in the saving rate we then develop and estimate a model of consumption saving and health decisions to evaluate which mechanisms are behind the decline using the estimated model we document that the rise in medical expenses and drop in the saving rate are driven mainly by progress in health technology during the years 1995 2010 by the reduction in co payment rates in the period 1986 1994 and by improvements in income processes for the years 1980 1985

the wealth age relation among the aged aged people face the problem of allocating over the rest of their lifetimes the wealth that they have accumulated during their working years this problem is fairly complex because they are uncertain about the dates of their death and because they may wish to use their wealth to finance general consumption or hold it to meet emergencies leave estates or maintain power or status whether skilled at dynamic programming or not aged people effectively do make these decisions what are the results some studies of the entire lifetime pattern of saving and wealth tend to support the simple life cycle model in which the aged use up their wealth to help finance consumption harold lydall for example found saving rates to increase and then decrease with age in the whole population and to be negative for the group aged 65 and over guarded support for the theory was found by franco modigliani and albert ando in britain and by dorothy projector in the united states more recently a f shorrocks examined the lifetime pattern of wealth holding in estate tax data for a single cohort and found the hump pattern that is characteristic of life cycle saving other evidence on wealth holding runs contrary to this however in a study of estate tax returns in washington d c james d smith found that wealth increased with age among the aged after controlling for other demographic variables examining national estate tax data john brittain found wealth to increase with age in the united states and a b atkinson and a j harrison reported the same pattern in england and wales in a sample of tiaa annuity recipients analyzed by james mulanaphy over half reported that their total savings had increased during retirement and another quarter reported that their savings had remained about the same in this paper i examine wealth holding patterns among aged married couples using survey data representing the entire aged population of the united states in 1968 the statistical analysis serves as a test of the hypothesis that emerges from life cycle theory and provides some further exploration into the economic behavior of the aged i find that the aged tend to increase their wealth over time

the causes of bargaining failure evidence from major league baseball abstract final offer arbitration in major league baseball provides an ideal setting for examining the empirical regularities that are associated with bargaining failure since final offers salaries and player statistics which provide the fundamental facts for the case are all readily available using data for players eligible for arbitration for 1990 93 we conduct a wide variety of empirical tests regarding the relationship between aggressive offers and arbitration outcomes we find that aggressive offers by players trigger arbitration and that more aggressive offers are associated with inferior financial outcomes in arbitration overall clubs appear to outperform players in arbitration unexpectedly high or low offers are less common for players who have previously been through arbitration which suggests that learning occurs our results are inconsistent with simple one sided asymmetric information models of arbitration the results are more consistent with an optimism model or a model in which so

insurance induced moral hazard a dynamic model of within year medical care decision making under uncertainty health insurance may lead individuals to overconsume medical care many studies explore this moral hazard using models that aggregate medical care decisions up to the annual level using employer employee matched data from the medical expenditure panel survey meps i estimate moral hazard using a dynamic model of within year medical care consumption that allows for endogenous health transitions variation in medical care prices and individual uncertainty within a health insurance year i then estimate moral hazard under a second set of conditions that are consistent with the assumptions of most annual decision making models the within year decision making model produces a moral hazard estimate that is 19 2 larger than the alternative model i highlight the importance of controlling for within year dynamics in a model of medical care consumption using a counterfactual policy simulation that implements the individual mandate provision of the 2010 patient protection and aordable care act i nd that full implementation of the policy decreases the percentage of uninsured individuals in the population being analyzed from 11 8 to 6 0 furthermore when all uninsured individuals are forced into coverage their predicted annual medical care expenditure increases by 45 5

civil war and u s foreign influence we study how foreign interventions affect civil war around the world in an infinitely repeated game we combine a gambling for resurrection mechanism for the influencing country with the canonical bargaining model of war in the influenced country to micro found sudden shifts in power among the domestic bargaining partners which are known to lead to war due to commitment problems we test two of our model predictions that allow us to identify the influence of foreign intervention on civil war incidence i civil wars around the world are more likely under republican governments and ii the probability of civil wars decreases with the u s presidential approval rates these results withstand several robustness checks and overall suggest that foreign influence is a sizable driver of domestic conflict

the persistence of financial distress using recently available proprietary panel data we show that while many 35 us consumers experience financial distress at some point in the life cycle most of the events of financial distress are primarily concentrated in a much smaller proportion of consumers in persistent trouble roughly 10 of consumers are distressed for more than a quarter of the life cycle and less than 10 of borrowers account for half of all distress events these facts can be largely accounted for in a straightforward extension of a workhorse model of defaultable debt that accommodates a simple form of heterogeneity in time preference but not otherwise

measurement error and earnings dynamics some estimates from the psid validation study previous empirical work on measurement error in survey earnings data has shown that the variance of the measurement error is roughly constant over time it is negatively correlated with true earnings and it is autocorrelated with previous measurement errors this article proposes a simple model in which the measurement error stems from underreporting of transitory earnings fluctuations and a white noise component the model fits well to data from the panel study of income dynamics validation study the results imply that autocorrelations in the changes of earnings can be estimated relatively accurately despite the presence of measurement error

health insurance and the demand for medical care evidence from a randomized experiment we estimate how cost sharing the portion of the bill the patient pays affects the demand for medical services the data come from a randomized experiment a catastrophic insurance plan reduces expenditures 31 percent relative to zero out of pocket price the price elasticity is approximately 0 2 we reject the hypothesis that less favorable coverage of outpatient services increases total expenditure for example by deterring preventive care or inducing hospitalization

private information and insurance rejections across a wide set of nongroup insurance markets applicants are rejected based on observable often high risk characteristics this paper argues that private information held by the potential applicant pool explains rejections i formulate this argument by developing and testing a model in which agents may have private information about their risk i first derive a new no trade result that theoretically explains how private information could cause rejections i then develop a new empirical methodology to test whether this no trade condition can explain rejections the methodology uses subjective probability elicitations as noisy measures of agents beliefs i apply this approach to three nongroup markets long term care disability and life insurance consistent with the predictions of the theory in all three settings i find significant amounts of private information held by those who would be rejected i find generally more private information for those who would be rejected relative to those who can purchase insurance and i show it is enough private information to explain a complete absence of trade for those who would be rejected the results suggest that private information prevents the existence of large segments of these three major insurance markets publication abstract

are americans saving optimally for retirement we solve each household s optimal saving decisions using a life cycle model that incorporates uncertain lifetimes uninsurable earnings and medical expenses progressive taxation government transfers and pension and social security benefits with optimal decision rules we compare household by household wealth predictions from the life cycle model using a nationally representative sample we find making use of household specific earnings histories that the model accounts for more than 80 percent of the 1992 cross sectional variation in wealth fewer than 20 percent of households have less wealth than their optimal targets and the wealth deficit of those who are undersaving is generally small

does medicare save lives health insurance characteristics shift at age 65 as most people become eligible for medicare we measure the impacts of these changes on patients who are admitted to hospitals through emergency departments for conditions with similar admission rates on weekdays and weekends the age profiles of admissions and comorbidities for these patients are smooth at age 65 suggesting that the severity of illness is similar on either side of the medicare threshold in contrast the number of procedures performed in hospitals and total list charges exhibit small but statistically significant discontinuities implying that patients over 65 receive more services we estimate a nearly 1 percentage point drop in 7 day mortality for patients at age 65 equivalent to a 20 reduction in deaths for this severely ill patient group the mortality gap persists for at least 9 months after admission

the economic effects of social security toward a reconciliation of theory and measurement abstract in this paper we argue that actuarial valuation of social security benefit streams is theoretically inconsistent with the assumption of pure life cycle motives instead we show that the simple discounted value of future benefits ignoring the possibility of death is often a good approximation to the relevant concept of value this observation motivates a re examination of existing empirical evidence concerning the economic effects of social security we focus our attention on studies of distributional equity and personal saving behavior in both cases we argue that the use of simple rather than actuarial discounting of survival contingent income streams produces results that differ dramatically from previous findings specifically estimates based on actuarial valuation may overstate the importance of redistribution between and within generations and may understate the depressive effect of social security on personal wealth accumulation by a factor of three or more

work stoppages and the theory of the offset factor evidence from the british columbian lumber industry one method of estimating losses resulting from work stoppages is to multiply the total number of man days lost during disputes by the average product of workers this statistic can be easily calculated using information typically available from government agencies but has obvious flaws for example the behavior of other firms not involved in disputes is ignored moreover when output is durable the impact on consumption is unknown since inventories can be used as buffers to assess the importance of these and other considerations i develop an alternative empirical framework and implement it using data from the british columbian lumber industry

aging in place housing maintenance and reverse mortgages we study the role of housing wealth in financing retirement consumption in our model retirees 1 derive utility benefits from remaining in their home aging in place and 2 choose in each period whether to maintain their house the evidence that we present shows that these features are important in explaining the saving decisions of the elderly the costs and the maintenance requirement of reverse mortgages rms reduce or eliminate the benefits of the loans for retirees who wish to do less maintenance we evaluate the impact of different loan features on retirees utility cash flows to lenders and to the government agency that provides mortgage insurance we show that combining rms with insurance against a forced home sale e g due to a move to a nursing home is pareto improving and can lead to increased demand for the loans due to product complementarities

the oregon health insurance experiment evidence from the first year in 2008 a group of uninsured low income adults in oregon was selected by lottery to be given the chance to apply for medicaid this lottery provides an opportunity to gauge the effects of expanding access to public health insurance on the health care use financial strain and health of low income adults using a randomized controlled design in the year after random assignment the treatment group selected by the lottery was about 25 percentage points more likely to have insurance than the control group that was not selected we find that in this first year the treatment group had substantively and statistically significantly higher health care utilization including primary and preventive care as well as hospitalizations lower out of pocket medical expenditures and medical debt including fewer bills sent to collection and better self reported physical and mental health than the control group

selection on moral hazard in health insurance economic analysis of market failure in insurance markets tends to analyze selection and moral hazard as distinct phenomena in this paper we explore the potential for selection on moral hazard in insurance markets by this we mean the possibility that moral hazard effects are heterogenous across individuals and that individuals selection of insurance coverage is affected by their anticipated behavioral response to coverage we examine these issues empirically in the context of employer provided health insurance in the united states specifically we break down the general

saving and the life cycle a cohort analysis abstract this paper examines the life cycle hypothesis with reference to japanese employees the study is based on panel data created from successive cross section data which is expected to give better results than past studies the sample was categorized by many elements one important result is that empirical testing of saving and the life cycle is crucially dependent upon the samples it is found that the majority of japanese employees have not accumulated wealth enough to assure consumption during retirement the paper however did not reject a hump shaped course of wealth accumulation under the assumption of myopic behavior

medicaid insurance in old age the old age provisions of the medicaid program were designed to insure retirees against medical expenses we estimate a structural model of savings and medical spending and use it to compute the distribution of lifetime medicaid transfers and medicaid valuations across currently single retirees compensating variation calculations indicate that current retirees value medicaid insurance at more than its actuarial cost but that most would value an expansion of the current medicaid program at less than its cost these findings suggest that for current single retirees the medicaid program may be of the approximately right size

the elasticity of intergenerational substitution parental altruism and fertility choice dynastic models common in macroeconomics use a single parameter to control the willingness of individuals to substitute consumption both intertemporally or across periods and intergenerationally or across parents and their children this article defines the concept of elasticity of intergenerational substitution egs and extends a standard dynastic model in order to disentangle the egs from the eis or elasticity of intertemporal substitution a calibrated version of the model lends strong support to the notion that the egs is significantly larger than one in contrast estimates of the eis suggests that it is at most one what disciplines the identification is the need to match empirically plausible fertility rates for the u s we illustrate the potential role of the egs in macroeconomics

the importance of bequests and life cycle saving in capital accumulation a new answer as the workhorse of consumption and saving research for the past four decades the life cycle model has proved flexible and useful for examining a variety of questions in a classic paper albert ando and franco modigliani 1963 p 56 stated a key assumption of the basic model t he individual neither expects to receive nor desires to leave any inheritance although the authors contended that the absence of a bequest motive was not critical to the heart of their results the assumption set off a long standing battle over the relative importance of different motives for saving in an influential study laurence kotlikoff and laurence summers 1981 estimated that a large fraction of the u s capital stock was attributable to intergenerational transfers modigliani and his collaborators vigorously disagreed and based on their own empirical work claimed that life cycle saving was the primary source of capital accumulation modigliani 1988 subsequent work has failed to reach a consensus since this debate began an important advance in the consumption literature has been the incorporation of uncertainty in life cycle models see e g r glenn hubbard et al 1995 we argue that allowing for uncertainty resolves the controversy over the importance of life cycle and bequest saving by showing that these motives for saving are overlapping and cannot generally be distinguished a dollar saved today simultaneously serves both a precautionary life cycle function guarding against future contingencies such as health shocks or other emergencies and a bequest function because in the likely event that the dollar is not absorbed by these contingencies it will be available to bequeath to children or other worthy causes under this view households have a bequest motive but bequests are given i e the motive is operative in only some states of the world wealth is something like traveler s checks you take them along on vacation just in case but odds are they will remain uncashed and available for sundry goods after the journey is complete we first demonstrate the result using a simple model and then argue that this approach reconciles the apparent importance of bequests with households declared focus on life cycle saving finally we consider implications of our analysis

heterogeneity in perceptions of national economic conditions empirical findings concerning economic voting differ according to the level of analysis employed a widely accepted explanation for the inconsistency between macroand microlevel evidence of economic voting is the high degree of random variation that plagues survey data according to this explanation aggregation purges individual level noise from mass opinions on policy issues and outcomes building on the research of bartels 1996 we debate the validity of this explanation by demonstrating that public evaluations of the national economy vary systematically with information media exposure political attitudes personal experiences and demographic characteristics furthermore we show that these sources of subjective heterogeneity produce systematic biases when national economic evaluations are aggregated these findings challenge a widely accepted notion that because error in individual level measures or expressions of preferences is random the aggregation of these individual measures ensures that they correctly represent the collective preference mpirical findings concerning the influence of the economy on political behavior differ depending on the level of analysis employed using aggregate level data numerous studies have established a statistical relationship between economic conditions and election outcomes or executive popularity e g kramer 1971 mackuen erikson and stimson 1992 on the basis of the macro level evidence alone one would have little reason to doubt that the economy matters in contrast individual level studies using survey data have produced only mixed evidence that voters consider economic conditions when evaluating the incumbent government and its leaders e g fiorina 1978 1981 kinder and kiewiet 1979 1981 moreover the strongest survey evidence of economic voting suggests that voters primarily care about national economic conditions not their personal financial situation this finding contradicts the egocentric theory posited by early macro level research that national economic indicators matter because they are correlated with personal financial circumstances the micro macro dichotomy in economic voting research reflects a similar dichotomy in research on voter sophistication and representation aggregate level studies tend to indicate that voters are reasonably well informed about the economy and make forward looking rather sophisticated voting decisions e g alesina londregan and rosenthal 1993 suzuki and chappell 1996 palmer and whitten 1999 these studies infer that mass political decisions conform to rational expectations or at least limited information rationality e g mackuen erikson and stimson 1992 in contrast to this macro level image of the voter individual level survey research has shown that the public in general has low levels of political sophistication lacking much knowledge of and interest in politics e g

strategic bargaining models and interpretation of strike data attrition screening and signalling models of strategic bargaining are characterized in terms of their predictions about the incidence mean duration and settlement rates of strikes and the terms of wage settlements these predictions are compared with the general features observed in empirical studies of strikes in canada and the united states conclusions are drawn about the types of models capable of generating these features and about the conformity of the models to the evidence methods are described for computing the numerical examples used to illustrate the models

old sick alone and poor a welfare analysis of old age social insurance programmes all individuals face some risk of ending up old sick alone and poor is there a role for social insurance for these risks and if so what is a good programme a large literature has analysed the costs and benefits of pay as you go public pensions and found that the costs exceed the benefits this article instead considers means tested social insurance mtsi programmes for retirees such as medicaid and supplemental security income we find that the welfare gains from these programmes are large moreover the current scale of mtsi in the u s is too small in the following sense if we condition on the current social security programme increasing the scale of mtsi by 1 3 benefits both the poor and the affluent when a payroll tax is used to fund the increase

life expectancy and old age savings rich people women and healthy people live much longer than their poor male and sick counterparts two extremes taken from our analysis of single people in the assets and health dynamics of the oldest old ahead dataset illustrate this point an unhealthy 70 year old male at the twentieth percentile of the permanent income distribution expects to live only 6 more years that is to age 76 in contrast a healthy 70 year old woman at the eightieth percentile of the permanent income distribution expects to live 16 more years thus making it to age 86 such significant differences in life expectancy could all else equal lead to significant differ ences in saving behavior a related observation is that people with high permanent incomes keep large amounts of assets until very late in life table 1 also based on the

what did medicare do the initial impact of medicare on mortality and out of pocket medical spending abstract we study the impact of the introduction of one of the major pillars of the social insurance system in the united states the introduction of medicare in 1965 our results suggest that in its first 10 years the establishment of universal health insurance for the elderly had no discernible impact on elderly mortality however we find a substantial reduction in the elderly s exposure to out of pocket medical expenditure risk specifically we estimate that the introduction of medicare was associated with a 40 decline in out of pocket spending for the top quartile of the out of pocket spending distribution a stylized expected utility framework suggests that the welfare gains from such reductions in risk exposure alone may be sufficient to cover almost two fifths of the costs of medicare these findings underscore the importance of considering the direct insurance benefits from public health insurance programs in addition to any indirect benefits from an effect on health

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

the interaction of public and private insurance medicaid and the long term care insurance market a long tradition in public finance examines how public programs can crowd out private activ ity in areas as diverse as education savings and insurance among others these studies typi cally focus on aggregate economic implications particularly for government expenditures and national savings in this paper we demonstrate that crowd out can also have an important effect on individual welfare specifically we show that the provision of even very incomplete public insurance can crowd out more comprehensive private policies by imposing a large implicit tax on private insurance benefits thus potentially increasing overall risk exposure for individuals we examine the interaction of public and private insurance for one of the largest uninsured financial risks facing the elderly in the united states long term care expenditures at 135 bil lion in 2004 long term care expenditures represented over 8 5 percent of total health expendi tures or all ages or roughly 1 2 percent of gdp moreover real long term care expenditures are projected to triple over the next 35 years due to rising medical costs and the aging of the baby boomers only 10 percent of the elderly however have any private long term care insurance and one third of expenditures are paid for out of pocket congressional budget office cbo 1999 cbo 2004 brown and finkelstein 2007 one potential explanation for the small size of the private market is that the public insurance provided by medicaid may crowd out demand for private insurance medicaid was designed to provide long term care insurance for the poor elderly mark v pauly 1989 1990 has established the qualitative result that as an incomplete but publicly funded source of long term care insur ance medicaid has the potential to reduce substantially demand for private long term care insur ance even among the nonpoor our work builds on this insight by quantifying the magnitude of medicaid s crowd out effect and the incomplete nature of medicaid coverage we also illustrate the mechanism behind medicaid s crowd out effect and are therefore able to assess the likely impact of alternative policies on private insurance demand we develop a utility based model of a 65 year old risk averse individual who chooses an opti mal intertemporal consumption path in the presence of uncertainty about long term care expen ditures we calibrate the model using data on the distribution of long term care expenditure risk common state medicaid rules and the prices and coverage of typical private long term care insurance policies

economics party and the vote causality issues and panel data conventional wisdom argues that national economic perceptions generally have an important impact on the vote choice in democracies recently a revisionist view has arisen contending that this link regularly observed in election surveys is mostly spurious according to the argument partisanship distorts economic perception thereby substantially exaggerating the real vote connection these causality issues have not been much investigated empirically despite their critical importance utilizing primarily american and secondarily british and canadian election panel surveys we confront directly questions of the time dynamic and independent variable exogeneity we find after all economics clearly matters for the vote indeed once these causality concerns are properly taken into account the impact of economic perceptions emerges as larger than previously thought as well the actual impact of partisanship is clearly reduced

strikes and wages a test of an asymmetric information model this paper describes a simple model of labor disputes based on the hypothesis that unions use strikes to infer the profitability of the firm the model posits the existence of a negatively sloped resistance curve between wages and strike duration in addition it offer a series of predictions relating wage and strike outcomes to changes in the expected profitability of the firm and changes in the alternative opportunities of striking workers these implications are tested using data on wage outcomes strike probabilities and strike durations for a large sample of collective bargaining agreements

cyclical uncertainty precautionary saving and economic growth this paper studies the interaction between cyclical uncertainty precautionary saving and economic growth in a stochastic endogenous growth model the analysis provides insight into the potential connection between technological uncertainty of the sort popularized in real business cycle models and the determinants of economic growth in a stochastic version of a popular model of endogenously determined economic growth the magnitude of the link between cyclical uncertainty and growth is quantified and found to be small in terms of its effect on the growth rate but possibly large in terms of its effect on levels of macroeconomic variables moreover the welfare costs of reduced cyclical uncertainty can be substantial owing to the lower historical rate of capital accumulation induced by a decrease in precautionary saving the chief implications of the model are found to be roughly consistent with the postwar experience of several countries although the predictions of the model with regard to growth rates are too small to explain much of the variation in growth rates across time or across countries

longitudinal analysis of strike activity this article presents an empirical study of strike activity in a panel of contract negotiations for some 250 firm and union pairs evidence is presented on two sources of variation in dispute rates changes in the characteristics of the collective bargaining agreement that affect subsequent strike outcomes and the effects of lagged strikes on the incidence and duration of subsequent disputes strike probabilities are significantly affected by the duration and expiration month of the previous agreement dispute rates are also increased by the occurrence of a short strike during the previous negotiations and reduced by the occurrence of a long strike

does medicare benefit the poor abstract measuring the progressivity of age targeted government programs is difficult because no single data set measures income and benefit use throughout life previous research using zip code as a proxy for lifetime income has found that medicare benefits flow primarily to the most economically advantaged groups and that the financial returns to medicare are often higher for the rich than the poor however our analysis produces the starkly opposed result that medicare is an extraordinarily progressive public program in dollar terms or welfare terms these new results owe themselves to our measurement of socioeconomic status as an individual s education rather than the geographically aggregated measures of income used by previous research we argue that individual education has important practical and conceptual advantages over geographically aggregated measures of income our results suggest the crucial importance of accurate poverty measurement in evaluating the progressivity of complex government programs like medicare or social security

the effect of labour relations legislation on strike incidence the impact on strike incidence of nine labour relations policy variables representing legislation in eleven canadian jurisdictions is estimated using logit analysis of 3 347 individual collective agreements mandatory strike votes compulsory dues check off and compulsory conciliation boards are associated with significantly lower strike probabilities prohibition of replacement workers and employer initiated strike votes are associated with significantly higher strike probabilities no significant association was found between strike incidence and the length of cooling off period following conciliation and negotiated or automatic reopeners policy impacts are interpreted in a framework emphasizing the influence of asymmetric inforrnation and joint costs on strikes

democratic accountability and retrospective voting a laboratory experiment understanding the incentives of politicians requires understanding the nature of voting behavior i conduct a laboratory experiment to investigate whether voters focus on the problem of electoral selection or if they instead focus on electoral sanctioning if voters are forward looking but uncertain about politicians unobservable characteristics then it is rational to focus on selection but doing so undermines democratic accountability because selection renders sanctioning an empty threat in contrast to rational choice predictions the experimental results indicate a strong behavioral tendency to use a retrospective voting rule additional experiments support the interpretation that retrospective voting is a simple heuristic that voters use to cope with a cognitively difficult inference and decision problem and in addition suggest that voters have a preference for accountability the results pose a challenge for theories of electoral selection and voter learning and suggest new interpretations of empirical studies of economic and retrospective voting

the determinants of strikes in the united states 1900 1977 this study aims to assess the recent debate that has emerged in the literature over the economic and organizational political models of strikes and to propose and test a synthesis of those models as an explanation for the pattern of strike activity in the united states since 1900 the paper begins with a review of strike activity in the post 1900 period and then develops a conceptual framework incorporating six factors the size of union membership economic conditions political events institutional arrangements psychological variables and the extent of rival unionism to explain this historical pattern the second part of the paper contains a regression analysis of strike activity over the 1900 1977 period the regression results show that both the economic factors of unemployment and inflation and various noneconomic factors such as changes in union membership the outbreak of world war ii and enactment of new deal legislation are significant in explaining variations in strike activity during t

learning in sequential wage negotiations theory and evidence when union firm pairs bargain sequentially and when unobserved components of firms abilities to pay are subject to correlated shocks unions that bargain later in a sequence can acquire valuable information by observing previous bargaining outcomes in their industry we derive the implications of this kind of learning in an asymmetric information model of wage negotiations and argue that the most robust implication is a lower incidence of strikes among followers than leaders in wage negotiations considerable empirical support for this implication is found in a long panel of canadian contract negotiations

the effects of public policy on strike duration hazard function estimates are utilized to analyze the effect of numerous public policy variables on strike duration based on 7 546 strikes in canada between 1967 and 1985 we find that only the mandatory strike vote substantially reduced conditional duration however the policy variables generally had a more favorable effect on reducing strike incidence so that on net they tended to reduce unconditional duration incidence times conditional duration specifically reduced unconditional duration was associated with the existence of conciliation and the requirement of a mandatory strike vote but the prohibition on replacement workers had a perverse effect
