gone with the wind valuing the visual impacts of wind turbines through house prices this study provides quantitative evidence on the local benefits and costs of wind farm developments in england and wales focussing on their visual environmental impacts in the tradition of studies in environmental public and urban economics housing sales prices are used to reveal local preferences for views of wind farm developments estimation is based on quasi experimental research designs that compare price changes occurring in places where wind farms become visible with price changes in appropriate comparison groups these groups include places close to wind farms that became visible in the past or where they will become operational in the future and places close to wind farms sites but where the turbines are hidden by the terrain all these comparisons suggest that wind farm visibility reduces local house prices and the implied visual environmental costs are substantial

an evaluation of the life cycle effects of minimum pensions on retirement behavior in this paper we explore the effects of the minimum pension program on welfare and retirement in spain this is done with a stylized life cycle model which provides a convenient analytical characterization of optimal behavior we use data from the spanish social security to estimate the behavioral parameters of the model and then simulate the changes induced by the minimum pension in aggregate retirement patterns the impact is substantial there is a threefold increase in retirement at 60 the age of first entitlement with respect to the economy without minimum pensions and total early retirement before or at 60 is almost 50 larger copyright 2007 john wiley sons ltd

social security pensions and retirement behavior within the family this paper estimates a structural model of family retirement using us data from the health and retirement study hrs it provides further insight into household retirement decision making and the reasons for interdependence in the retirement decisions of each spouse improvements in hrs data and matched employer provided pension histories allow more precise identification of key parameters governing interdependent behaviour within the household in an earlier study we found that interdependence was due to preferences rather than coordination of retirement incentives in the budget and in particular that it is not a correlation in preferences but the appearance of the spouse s retirement status in the husband s and wife s utility function that is largely responsible for coordination of retirement between spouses we now find that a measure of how much each spouse values being able to spend time in retirement with the other accounts for a good portion of that apparent interdependence for the wife the husband s retirement status influences her retirement decision only if she values spending time in retirement with her husband for husbands the effect of having the wife already retired on his retirement decision is roughly doubled if he enjoys spending time in retirement with his wife but there is some effect even if he does not this is consistent with our earlier findings that the husband is more influenced by having a retired spouse than the wife is the increase in the extent of the dependence of the wife s labour supply on the husband s retirement from our past work probably is traceable to better measurement of the opportunity set facing the husband in hrs data once estimated we use the model to investigate the labour supply effects of alternative social security policies examining the effect of dividing credit for earnings evenly between spouses or of basing social security benefits on the amounts accumulated in private accounts both policies change the relative importance of spouse and survivor social security benefits within the household and both raise the relative reward to work later in the life cycle the incentives created are modest and retirement responds accordingly nevertheless at some ages such as 65 there may be as much as a 6 increase in the old age work force under privatized accounts copyright 2004 john wiley sons ltd

distinctively different a new approach to valuing architectural amenities we propose a method to estimate the capitalized value of the architectural design quality of a neighbourhood our economic design premium is identified by spatially differentiating property prices and design quality within neighbourhoods and comparing the differences across neighbourhoods we apply our method to 47 conservation area neighbourhoods in england in which we analyse around 7900 property transactions and interview more than 500 residents we find a capitalization effect of about 25 4 38 7k associated with a one step increase on a five step scale ranging from not at all distinctive to very distinctive our results suggest that this effect is at least partially driven by an architectural externality

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

valuing school quality using boundary discontinuities abstract existing research shows that house prices respond to local school quality as measured by average test scores however higher test scores could signal higher academic value added or higher ability more sought after intakes in our research we show that both school value added and student prior achievement linked to the background of children in schools affect households demand for education in order to identify these effects we improve the boundary discontinuity regression methodology by matching identical properties across admissions authority boundaries by allowing for boundary effects and spatial trends by re weighting our data towards transactions that are closest to district boundaries by eliminating boundaries that coincide with major geographical features and by submitting our estimates to a number of novel falsification tests our results survive this battery of tests and show that a one standard deviation change in either school average value added or prior achievement raises prices by around 3

the effect of pension plan type on retirement age distinguishing plan incentives from career length preferences the widespread movement from dened benet db plans to dened contribution dc plans over the past few decades has transferred much of the retirement savings risk from the institution to the individual particularly in the private sector this study uses the retirement condence

the impact of supply constraints on house prices in england we test the theoretical prediction that house prices respond more strongly to changes in local earnings in places with tight supply constraints using a unique panel dataset of 353 local planning authorities in england between 1974 and 2008 exploiting exogenous variation from a policy reform vote shares and historical density to identify the endogenous constraints measures we find that regulatory constraints have a substantive positive impact on the house price earnings elasticity the effect of constraints due to scarcity of developable land is largely confined to highly urbanised areas and uneven topography has a quantitatively less meaningful impact

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

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

the economic functions of private pensions an empirical analysis this paper presents an empirical analysis of the economic functions of defined benefit db pensions firms providing pensions choose between db and defined contribution formats the latter is essentially a tax preferred savings account the former may fill other roles determinants of firms choice of plan are estimated using plan sponsors reports to the internal revenue service firms that are larger are unionized employ mainly one sex invest in specific training and pay lower wages are more likely to provide db coverage these results suggest that the economic role of pensions is broader than mere provision of tax preferred savings accounts

flexible practices for mass production goals economic governance in the indian automobile industry this paper explains the remarkable restructuring of the indian automobile industry it argues that firms have had to deploy new governance modes flexible industrial practices for economic coordination to overcome supply bottlenecks and meet expanding demand firms that failed to adopt these practices performed poorly while firms that attained economies of scale were able to graduate to exploiting economies of scope the industry experience suggests that new governance modes can serve mass production goals in developing economies and not just cushion market volatility for which they were designed

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

labor force dynamics of older married couples this article analyzes the dynamics of joint labor force behavior of older couples in the united states using the retirement history survey rhs i analyze the determinants of joint retirement and the effect of one spouse s labor force status on the labor force transitions of the other spouse the results reveal strong associations between the labor force transition probabilities of one spouse and the labor force status of the other spouse these result from structural differences in exit and entry behavior by the spouse s status several lagged endogenous variables have substantial effects on behavior even after controlling for unobserved heterogeneity

what are cities worth land rents local productivity and the total value of amenities abstract this paper models how to use widely available data on wages and housing costs to infer land rents local productivity and the total value of local amenities in the presence of federal taxes and locally produced nontraded goods i apply the model to u s metropolitan areas with the aid of visually intuitive graphs the results improve measures of productivity and feature large differences in land rents wage and housing cost differences across metropolitan areas are accounted for more by productivity than quality of life differences regressions using individual amenities reveal that the most productive and valuable cities are typically coastal sunny mild educated and large

the perceived budget constraint under social security evidence from reentry behavior if as is usually assumed older individuals face a continuous choice of work hours without fixed costs or take account of the actuarial adjustment of social security benefits postponed as a result of the earnings test the earnings limit should not affect their labor supply before age 65 we test and reject these assumptions by estimating the hazard function for labor market reentry after retirement using white men in the retirement history survey we find that the earnings limit does affect reentry and that older men behave myopically responding to current benefits rather than to social security wealth several policy implications follow

income tax policy and lifetime labor supply abstract a progressive income tax structure provides incentives for individuals to alter their rate of work and their age of retirement compared to a zero tax or proportional tax equilibrium progressive taxation induces individuals to take less leisure in the form of retirement in exchange for more leisure during the worklife especially at high wage levels the imposition of a special pension tax provision on top of a progressive tax structure offsets the distortion on leisure alternatives imposed by progressivity indeed the pension tax deferral provision can neutralize the impact of tax progressivity on the work profile over life the magnitude of these tax inducements in the u s tax structure are non trivial and therefore are expected to alter labor supply decisions over the lifetime the model finds empirical support using data from the social security newly entitled beneficiaries survey

the implicit pension contract developments and new directions pension economics has emerged as a separate literature over the past decade some of the early pension work was devoted to financial issues including implications of pensions for savings rates and portfolio allocation most new developments however have stemmed from research surrounding labor markets this research has led to an implicit contract theory of pensions a theory that has pensions playing a more complicated role in worker firm relation than heretofore realized the theory explains much of economic behavior in labor markets and bridges a gap between labor and financial literatures this essay describes the genesis for these ideas and traces some of the most important research results in the area an equal amount of spece is devoted to a consideration of likely directions for future research

social security and retirement across the oecd abstract employment to population ratios differ markedly across organization for economic cooperation and development oecd countries especially for people aged over 55 years in addition social security features differ markedly across the oecd particularly with respect to features such as generosity entitlement ages and implicit taxes on social security benefits this study postulates that differences in social security features explain many differences in employment to population ratios at older ages this conjecture is assessed quantitatively with a life cycle general equilibrium model of retirement at ages 60 64 years the correlation between the simulations of this study s model and observed data is 0 67 generosity and implicit taxes are key features to explain the cross country variation whereas entitlement age is not

effects of social security policies on benefit claiming retirement and saving abstract an enhanced version of a structural model jointly explains benefit claiming wealth and retirement including reversals from states of lesser to greater work the model is estimated with health and retirement study data alternative beliefs about the future of social security affect claiming behavior effects of three potential policies are also examined increasing the early entitlement age increasing the full retirement age and eliminating the payroll tax for seniors predicted responses to increasing the full entitlement age are sensitive to beliefs

compensating differentials and the social benefits of the nfl abstract we use hedonic rent and wage equations to measure compensating differentials in central cities and metropolitan areas with franchises of the national football league rents are about 8 percent higher in the central cities but this impact may not carry over to broader geographical areas wages are about 2 percent lower in areas with teams but the standard error on this parameter is large the central city results indicate that sports franchises appear to be a public good once these quality of life benefits are included in the calculus the large public expenditure on new stadiums appears to be a good investment for cities and their residents

health insurance and retirement of married couples summary most health insurance in the usa is provided by employers until eligibility for public health insurance medicare begins at age 65 retiring before 65 exposes workers who lack retiree health insurance coverage to the risk of catastrophic medical expenditure we solve and estimate a dynamic model of the employment behavior of older married couples that includes risky medical expenditure and health insurance parameter estimates imply that the risk reducing feature of health insurance can account for about half of the observed association between retiree health insurance and employment for married men but can account for only one tenth of the much larger observed association for married women policy simulations imply very small effects on employment of changing the age of eligibility for medicare from 65 to 67 copyright 2006 john wiley sons ltd

capitalising the value of free schools the impact of supply characteristics and uncertainty there has been a growing literature in both the us for example haurin and brasington 1996 and black 1999 and the uk for example gibbons machin 2003 that estimates the way in which school quality is capitalised into house prices cheshire and sheppard 1995 and 1999 estimated hedonic models in which the quality of the secondary school to which a household was assigned was a significant variable which provided evidence that secondary school quality was being capitalised into the price of houses in contrast gibbons and machin concluded that primary schools were more significant each of these analyses is predicated on the assumption that the value of local schools should be reflected in the value of houses we argue here that this is rather too simple we should expect variation in the capitalised price of a given school quality at either primary or secondary level according to the elasticity of supply of school quality in the local market the certainty with which that quality can be expected to be maintained over time and the suitability of the dwelling to accommodate children these factors will vary systematically between and perhaps within cities this paper explores the sources and the impact of such variations as well as the impact of model specification the results provide new evidence on the complex and subtle ways in which housing markets capitalise the value of local public goods such as school quality and perhaps most importantly suggest that this is highly non linear houses in the catchment areas of only the best state schools command substantial premiums but such capitalised values can be very substantial indeed

towards a micro founded theory of aggregate labour supply we build a heterogeneous agents life cycle model that captures a large number of salient features of individual male labour supply over the life cycle by education both along the intensive and extensive margins the model provides an aggregation theory of individual labour supply firmly grounded on individual level micro evidence and is used to study the aggregate labour supply responses to changes in the economic environment we find that the aggregate labour supply elasticity to a transitory wage shock is 1 75 with the extensive margin accounting for 62 of the response furthermore we find that the aggregate labour supply elasticity to a permanent compensated wage change is 0 44

a direct test of the homevoter hypothesis abstract we propose a methodology that facilitates a direct test of the homevoter hypothesis which posits that homeowners vote in favor of public projects they perceive increase residential property values and against those that do not first we estimate how pre referendum events that signal a higher probability that the public project will be undertaken impact local residential property values before the referendum is held these pre referendum impacts are considered noisy signals to homeowners about the market s assessment of the net marginal benefits of the project second we aggregate these market signals to the precinct level and relate them to precinct level voting results concerning the proposed project we apply this two step approach to the 2004 referendum in arlington texas for a publicly subsidized stadium for the nfl dallas cowboys the analysis supports the homevoter hypothesis and establishes a possible methodology for future evaluations in this small but growing empirical literature

explaining applications to the u s disability system a semiparametric approach this study investigates the determinants of applications for u s disability benefits between 1986 and 1993 using a semiparametric discrete factor procedure separately for men and women approximating a dynamic optimization model the estimation accounts for a variety of potential biases that were unaddressed in prior studies our results indicate different responses of men and women to variations in policy measures past labor earnings and fringe benefits as well as benefit eligibility and benefit amounts clearly affect application behavior

separating urban agglomeration economies in consumption and production abstract in this paper we estimate the net agglomeration economies on the consumption side as well as the production side using japanese city based data from 1992 when interregional net migration nearly ceased we show that doubling city size increases the nominal wage by approximately 10 but decreases the real wage by approximately 7 12 the 10 increase of the nominal wage is attributed to the productivity increase in production activities while the 7 12 decrease of the real wage is a compensation for the net agglomeration economies which are the benefits from product variety minus the costs of congestion in other words city bigness not only enhances the productivity of firms but also brings net agglomeration economies to households in this way we separate the net agglomeration economies on the production side from those on the consumption side

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

employment transitions and computer use of older workers in our work we study the role of information and communication technology ict skills and their utilization in the retirement decision we provide empirical evidence based on italian panel data in favour of the hypothesis that ceteris paribus better educated male employees with ict know how retire later such effect is stronger the longer the time horizon considered and its magnitude is remarkably larger than the one observed in us and germany in previous studies we also document that ict do not play a crucial role in the retirement decision of women our results are robust to the estimation strategy adopted

policy effects in hyperbolic vs exponential models of consumption and retirement this paper constructs a structural retirement model with hyperbolic preferences and uses it to estimate the effect of several potential social security policy changes estimated effects of policies are compared using two models one with hyperbolic preferences and one with standard exponential preferences sophisticated hyperbolic discounters may accumulate substantial amounts of wealth for retirement we find it is frequently difficult to distinguish empirically between models with the two types of preferences on the basis of asset accumulation paths or consumption paths around the period of retirement simulations suggest that despite the much higher initial time preference rate individuals with hyperbolic preferences may actually value a real annuity more than individuals with exponential preferences who have accumulated roughly equal amounts of assets this appears to be especially true for individuals with relatively high time preference rates or who have low assets for whatever reason this affects the tradeoff between current benefits and future benefits on which many of the retirement incentives of the social security system rest simulations involving increasing the early entitlement age and increasing the delayed retirement credit do not show a great deal of difference whether exponential or hyperbolic preferences are used but simulations for eliminating the earnings test show a non trivially greater effect when exponential preferences are used

health longevity and retirement reform abstract in this paper we study alternative retirement reforms designed to achieve fiscal sustainability in the face of demographic change we are particularly interested in the heterogeneous effects across demographic groups as improvements in health and longevity have not been uniform across the population to this end we develop a dynamic structural life cycle model of heterogeneous agents who face health mortality and income risk we consider the following policy reform measures 1 increasing the early access age to old age retirement 2 raising income taxes 3 lowering old age retirement benefits and 4 lowering old age retirement and disability benefits we find that of the considered policies proportionally lowering old age retirement and disability benefits results in the highest average welfare for all education categories it is also the most successful at boosting employment

valuing rail access using transport innovations this paper uses a powerful empirical method to evaluate the benefits of rail access to consumers we study the effects on house prices of a transport innovation that altered the distance to the nearest station for some households but left others unaffected the transport innovation we study is the construction of new stations in london in the late 1990s using this innovation we implement a quasi experimental approach that allows us to avoid the biases inherent in cross sectional valuation work our evidence on distance station effects on local prices identified through distance changes induced by the transport innovation suggests that households value rail access and that these valuations are large compared to the valuations of other local amenities

the energy costs of historic preservation we explore the impact of historic preservation policies on domestic energy consumption using panel data for england from 2006 to 2013 and employing a fixed effects strategy we document that i rising national energy prices induce an increase in home energy efficiency installations and a corresponding reduction in energy consumption and ii this energy saving effect is significantly less pronounced in conservation areas and in places with high concentrations of listed buildings where the adoption of energy efficiency installations is typically more costly and sometimes legally prevented altogether historic preservation policies increase private energy costs and the social cost of carbon per designated dwelling by around 11 600 19 100 and 2 400 4 000 respectively these costs ought to be weighed against any benefits of preservation

the welfare economics of land use planning abstract this paper presents an empirical methodology for the evaluation of the benefits and costs of land use planning the technique is applied in the context of the town and country planning system of the uk and examines the gross and net benefits of land use regulation and their distribution across income groups the results show that the welfare and distributional impacts can be large

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

age discrimination laws and labor market efficiency in lazear s model of long term incentive contracts age discrimina tion laws barring age based involuntary terminations preclude such contracts reducing efficiency alternatively such laws may serve as precommitment devices for these contracts without pre venting firms from offering strong financial incentives to induce retirement at specific ages in this case age discrimination laws may encourage lazear contracts hence increasing efficiency we assess evidence on these alternative interpretations using variation in state and federal age discrimination laws the evidence indicates that age discrimination laws steepen age earnings profiles for co horts entering the labor market suggesting that these laws encour age the use of lazear contracts

intergenerational mobility in the very long run florence 1427 2011 we examine intergenerational mobility in the very long run across generations that are six centuries apart we exploit a unique dataset containing detailed information at the individual level for all people living in the italian city of florence in 1427 these individuals have been associated using their surnames with their pseudo descendants living in florence in 2011 we find that earnings elasticity is about 0 04 much higher than predicted by traditional models of intergenerational mobility we also find an even stronger role for real wealth inheritance and evidence of persistence in belonging to certain elite professions our results are confirmed when we account for the quality of the pseudo links and when we address the potential selectivity bias due to the differential survival rates across surnames we argue that the quasi immobility of pre industrial society and the positional advantages in the access to certain professions might explain in part the long lasting effects of ancestors socioeconomic status

on the price of land and the value of amenities a house represents not only a bundle of structural characteristics but also a set of location specific characteristics adding locational coordinates and site area to other house characteristics makes it possible to estimate a land rent surface as well as thle hedonic prices attached to local patterns of land use and other neighbourhood characteristics one can then estimate how the value of such location specific characteristics are capitalized into land prices this analysis illustrated with estimates based on data from two british towns has a number of wider implications it generates a more parsimonious method of estimating amenity values it also reveals likely systematic biases produced by conventional hedonic studies which exclude land and location finally it clarifies the conceptual definition of land and suggests that monocentric models can perform well despite recent criticism

dangerous flexibility retirement reforms reconsidered flexible retirement is supposed to increase labor supply of older workers without touching the third rail of pension politics the highly unpopular increase of the retirement age while this may have intuitive appeal this paper shows that it might be wishful thinking economic theory tells us that flexible retirement policies can have a zero or positive effect on labor force participation while the effect on hours worked can be positive or negative depending on the distribution of leisure preferences thus the overall effect is ex ante unclear empirical results from nine oecd countries show that the effect on labor force participation is ex post small and positive while the effect on hours worked is negative overall there is no evidence of the desired positive effect on total labor supply rather we see evidence of a dangerous decline in total labor supply we conclude that the flexibility reforms enacted so far have failed to increase old age labor supply and delineate several alternative options to achieve this aim

the labour supply effect of the abolition of the earnings rule for older workers in the united kingdom high effective tax rates on work at and around state pension age deter participation an example is the earnings test operating in several oecd countries the united states abolished its test for the 65 age group in 2000 the united kingdom offers a natural experiment of this reform as it abolished its test known as the earnings rule in 1989 we examine the effect of this change taking account of the opportunity to defer pension rights abolition of the rule raised working hours of older male workers by around 4 hours a week with a lesser impact on women s behaviour

lifetime consumption and investment retirement and constrained borrowing retirement flexibility and inability to borrow against future labor income can significantly affect optimal consumption and investment with voluntary retirement there exists an optimal wealth to wage ratio threshold for retirement and human capital correlates negatively with the stock market even when wages have zero or slightly positive market risk exposure consequently investors optimally invest more in the stock market than without retirement flexibility both consumption and portfolio choice jump at the endogenous retirement date the inability to borrow limits hedging and reduces the value of labor income the wealth to wage ratio threshold for retirement and the stock investment

social security and cross country differences in hours a general equilibrium analysis abstract i develop a general equilibrium life cycle model with an intensive and extensive margin of labor supply and endogenous human capital accumulation i use the model to assess the effects of changes to various features of social security on labor supply outcomes of particular interest are changes to the scale of the program and to the relevant eligibility rules i find that the cross country differences in social security programs account for at least 79 of the differences in employment rates of people aged 55 64 and 17 31 of the differences in aggregate hours worked between the us and continental europe

the value of school facility investments evidence from a dynamic regression discontinuity design author s cellini stephanie riegg ferreira fernando rothstein jesse abstract despite extensive public infrastructure spending surprisingly little is known about its economic return in this paper we estimate the value of school facility investments using housing markets standard models of local public goods imply that school districts should spend up to the point where marginal increases would have zero effect on local housing prices our research design isolates exogenous variation in investments by comparing school districts where referenda on bond issues targeted to fund capital expenditures passed and failed by narrow margins we extend this traditional regression discontinuity approach to identify the dynamic treatment effects of bond authorization on local housing prices student achievement and district composition our results indicate that california school districts underinvest in school facilities passing a referendum causes immediate sizable increases in home prices implying a willingness to pay on the part of marginal homebuyers of 1 50 or more for each 1 of capital spending these effects do not appear to be driven by changes in the income or racial composition of homeowners and the impact on test scores appears to explain only a small portion of the total housing price effect c 2010 by the president and fellows of harvard college and the massachusetts institute of technology

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

a life cycle model of health and retirement the case of swedish pension reform abstract sweden is one of the few western economies to have undertaken a large pension reform in recent years this was done with great expectations but little formal analysis in this paper we develop a life cycle labor supply model to quantify the predicted labor supply implications of this reform in our framework individuals choose when to stop working and given eligibility criteria when if to apply for disability and pension benefits agents are heterogeneous in skills and receive exogenous shocks to health throughout their life we find that the new pension system creates large incentives for the continued employment of older workers this is promising news for countries grappling with pension reform and indicates that there are significant lessons to be learned from the swedish case

how will 401 k pension plans affect retirement income two decades ago most workers with pensions had a defined benefit db plan the employer made necessary contributions and investments to meet promised pension benefit payments when the employee retired by 1993 the tide had turned more than half of covered employees participated primarily in defined contribution dc pensions such as 401 k plans employee benefit research institute ebri 1997 this dramatic shift was associated as well with growing concerns about the emerging 401 k plans some viewed 401 k plans as a crisis waiting to happen when current generations having made minimal or no contributions to their dc plan retired with inadequate pension asset balances karen ferguson and kate blackwell 1995 anne willette 1995 another concern was that workers switching jobs would use the lump sum distributions for houses boats or other purchases rather than reinvesting them in another retirement account ellen e schultz 1995 u s department of labor usdol 1998a in a similar vein newly retired workers may not roll over the assets into an annuity and therefore risk spending down their retirement wealth too early e g jeffrey r brown and mark j warshawsky 2001 the most serious charge against 401 k plans

collective efficiency growth path for small scale industry this study is concerned with the growth of small local industry in developing countries and explores one particular route for understanding and fostering such growth it focuses on the clustering of firms and the competitive advantage which they derive from local external economies and joint action captured in the concept of collective efficiency following a conceptual discussion the article explores the economic and institutional conditions which enhance or hinder collective efficiency this includes a case study which suggests that responding to opportunity and crisis requires shifting from mere reliance on external economies to joint action and from ascribed to earned trust

saving and investing for early retirement a theoretical analysis we study optimal consumption and portfolio choice in a framework where investors adjust their labor supply through an irreversible choice of their retirement time we show that investing for early retirement tends to increase savings and reduce an agent s effective relative risk aversion thus increasing her stock market exposure contrary to common intuition an investor might find it optimal to increase the proportion of financial wealth held in stocks as she ages and accumulates assets even when her income and the investment opportunity set are constant the model predicts a decrease in risk aversion following strong market gains like those observed in the nineties

a structural dynamic analysis of retirement behaviour in the netherlands this study focuses on determinants of elderly labour force participation and retirement decisions in the netherlands this is analysed by a dynamic programming model for the simultaneous choice of retirement age and route which includes social insurance and private pensions eligibility conditions for early retirement lifecycle wage and health profiles and layoffs special attention is given to opportunities for and the effect of participation policies results show that institutional structures of benefit and pension programmes are prime determinants of retirement particularly eligibility conditions and potential substitution between exit routes and that dynamic aspects are relevant for understanding retirement behaviour copyright 2004 john wiley sons ltd

economic determinants of workers retirement decisions the landscape for older workers has changed dramatically in recent decades governments have made cuts to public pension programs private pensions have shifted from defined benefit to defined contribution plans equity and housing markets have been unusually volatile and workers have experienced declining morbidity and mortality at the same time the labor force participation rate for older men and women has been rising over the past two decades implying later retirement are these phenomena related this paper reviews the large and growing body of literature exploring the economic determinants of workers retirement decisions including public and private pensions wealth and savings health and health insurance and labor demand

social security liquidity and early retirement abstract this paper investigates the effect of social security on retirement decisions it argues that it is important to take realistic account of how recipients evaluate potential benefit flows the paper presents a simple retirement model in which liquidity constraints prompt individuals to use higher than market discount rates in evaluating future pension benefits as a consequence even an apparently actuarially fair early retirement benefit could on average discourage continued work using data on individual retirement decisions i find support for the argument that this phenomenon contributes to some of the observed increase in early retirement

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

crowd out effects of place based subsidized rental housing new evidence from the lihtc program abstract since its inception in 1987 the low income housing tax credit lihtc program has ballooned into the largest ever source of subsidized construction of low income housing in the united states accounting for one third of all recent multi family rental construction this paper examines the crowd out effects of this increasingly important source of low moderate income housing to do so we analyze the impact of lihtc construction at three different levels of geography msa county and 10 mile radius circles this allows us to employ increasingly extensive geographic fixed effects that help to difference away unobserved factors political variables are also used as instruments to further facilitate identification in all of our models iv estimates yield substantially greater crowd out than ols confirming the endogenous attraction of lihtc development to areas ripe for new construction our most robust iv estimates indicate that nearly 100 of lihtc development is offset by a reduction in the number of newly built unsubsidized rental units although the confidence band around this point estimate allows for less dramatic assessments additional estimates suggest that lihtc development has a much more moderate impact on construction of owner occupied housing but these estimates are imprecise overall while lihtc development may well affect the location of low moderate income rental housing opportunities our estimates suggest that the impact of the program on the number of newly developed rental housing units appears to be small

economic determinants of workers retirement decisions economic determinants of workers retirement decisions the landscape for older workers has changed dramatically in recent decades governments have made cuts to public pension programs private pensions have shifted from defined benefit to defined contribution plans equity and housing markets have been unusually volatile and workers have experienced declining morbidity and mortality at the same time the labor force participation rate for older men and women has been rising over the past two decades implying later retirement are these phenomena related this paper reviews the large and growing body of literature exploring the economic determinants of workers retirement decisions including public and private pensions wealth and savings health and health insurance and labor demand

voluntary and involuntary early retirement an international analysis recent literature makes a distinction between voluntary and involuntary early retirement where involuntary early retirement results from employment constraints rather than from a preference for leisure relative to work this article analyses voluntary and involuntary early retirement based on international microdata covering 19 industrialized countries the results show that involuntary early retirement is particularly widespread in continental europe countries facing economic recessions and having strict employment protection legislation have higher shares of involuntary retirements among early retirees generous early retirement provisions of the social security system do not only make voluntary early retirement more attractive for individuals but also induce firms to push more employees to retire early

retirement pensions and ageing we study the effects of demographic shocks and changes in the pension system on the macroeconomic performance of an advanced small open economy facing a given world interest rate we construct an overlapping generations model which includes a realistic description of the mortality process individual agents choose their optimal retirement age taking into account the time and age profiles of wages taxes and the public pension system the early retirement provision in most pension systems acts as a trap inducing most workers to retire well before the normal retirement age simulations show that pension reform must be drastic for it to have any effects on the retirement behaviour of workers

housing market spillovers evidence from the end of rent control in cambridge massachusetts we measure the capitalization of housing market externalities into residential housing values by studying the unanticipated elimination of stringent rent controls in cambridge massachusetts in 1995 pooling data on the universe of assessed values and transacted prices of cambridge residential properties between 1988 and 2005 we find that rent decontrol generated substantial robust price appreciation at decontrolled units and nearby never controlled units accounting for a quarter of the 7 8 billion in cambridge residential property appreciation during this period the majority of this contribution stems from induced appreciation of never controlled properties residential investment explains only a small fraction of the total

quality of the business environment versus quality of life do firms and households like the same cities this paper develops a new measure of the quality of business environment that complements existing measures of the quality of life an annual panel of these measures is constructed and analyzed for 37 cities from 1977 to 1995 findings indicate that many cities attractive to firms are unattractive to households and vice versa in addition the size of a city s workforce increases with improvements in the quality of the business environment in contrast cities most likely to be dominated by retirees are those that are less attractive to firms additional specifications support theoretical arguments that retirees are drawn to cities in which local attributes are capitalized into lower wages rather than higher rents

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

spillovers from foreign direct investment within or between industries this paper contributes an estimation framework to measure both technological and linkage externalities from foreign direct investment fdi empirical research dealt mainly with intra industry spillovers from fdi with restrictive treatment of inter industry effects until recently however as optimal organization of the multinational corporation mnc involves minimization of profit losses due to leakage of technical information to competitors host country firms within the mnc s sector experience limited productivity gains ensuing fdi host country producers in other sectors may benefit for example mncs transfer knowledge to local downstream clients or outsource to local upstream suppliers hence fdi substitutes within sector domestic investment but complements it across sectors the net impact on aggregate capital formation by host country producers hinges on the interaction between linkages and spillovers estimations based on the colombian manufacturing census yield the sectoral pattern of fdi spillovers displaying knowledge propagation between but not within industries the findings reveal outsourcing relationships of mncs with local upstream suppliers as the channel of diffusion

technique and system the spread of japanese management techniques to developing countries in this paper a distinction is drawn between the isolated use of individual japanese management techniques and their adoption in an integrated package as part of a production system although the use of individual techniques does confer significant benefits to innovating firms it is clear from international experience that the major gains arise from systemic application the central objective of this paper is to explore whether there are obstacles specific to less developed countries ldcs in the systemic application of japanese management techniques the major forces driving the adoption of these new management techniques are reviewed based upon research in latin america india and zimbabwe then three major ldc specific factors affecting systemic adoption are considered human resources interfirm cooperation and management

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

interactive property valuations this paper estimates models of social interactions within residential neighborhoods using data on neighborhood clusters for standard metropolitan areas in the united states from the american housing survey for 1985 and 1989 it examines eects of social interactions in the form of reaction functions for homeowners valuation of their properties at the level of the immediate residential neighborhood with neighborhoods consisting of a randomly chosen dwelling unit and about ten nearest neighbors the paper identifies the eect of endogenous social interactions to be significant and large ranging from 0 587 to 0 770 and much more important then the dynamic autoregressive structure of the model when both variables are present and both are significant the interactive regressions that it reports improve upon commonly used hedonic regressions as well the paper provides empirical support for the notion common in the real estate world of the importance of neighboring properties in property valuations

consumption retirement and social security evaluating the efficiency of reform that encourages longer careers abstract this paper proposes and analyzes a social security reform in which individuals no longer face the oasi payroll tax after say age 54 or a career of 34 years and their subsequent earnings have no bearing on their benefits we first estimate parameters of a life cycle model our specification includes non separable preferences and possible disability it predicts a consumption expenditure change at retirement we use the magnitude of the expenditure change together with households retirement age decisions to identify key structural parameters the estimated magnitude of the change in consumption expenditure depends importantly on the treatment of consumption by adult children of the household simulations indicate that the reform could increase retirement ages one year or more equivalent variations could average more than 4000 per household and income tax revenues per household could increase by more than 14 000

disability benefit generosity and labor force withdrawal abstract a key component for estimating the optimal size and structure of disability insurance di programs is the elasticity of di claiming with respect to benefit generosity yet in many countries including the united states all workers face identical benefit schedules which are a function of one s labor market history making it difficult to separate the effect of the benefit level from the effect of unobserved preferences for work on individuals claiming decisions to circumvent this problem we exploit exogenous variation in di benefits in austria arising from several reforms to its di and old age pension system in the 1990s and 2000s we use comprehensive administrative social security records data on the universe of austrian workers to compute benefit levels under six different regimes allowing us to identify and precisely estimate the elasticity of di claiming with respect to benefit generosity we find that over this time period a 1 increase in potential di benefits was associated with a 1 2 increase in di claiming

tiebout sorting and neighborhood stratification tiebout s classic 1956 paper has strong implications regarding stratification across and within jurisdictions predicting in the simplest instance a hierarchy of internally homogeneous communities ordered by income typically urban areas are less than fully stratified and the question arises how much do departures from standard tiebout assumptions contribute to observed within neighborhood mixing this paper quantifies the separate effects of employment geography via costly commuting and preferences for housing attributes on neighborhood stratification it does so using an equilibrium sorting model estimated with rich census micro data simulations based on the model and credible preference estimates show that counterfactual reductions in commuting costs lead to marked increases in racial and education segregation and to a lesser degree increases in income segregation given that households now find it easier to locate in neighborhoods with like households while turning off preferences for housing characteristics increases racial segregation especially for blacks doing so reduces income segregation indicating that heterogeneity in the housing stock serves to stratify households based on ability to pay further we show that differences in housing help to accentuate differences in the consumption of local amenities

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

part time work and health among older workers in ireland and britain part time pt work is viewed as a viable option for people who wish to have a gradual transition to retirement from a policy viewpoint this may help to alleviate some labour supply shortages and fiscal pressures especially in the context of the ageing population factors such as health or pension provision may influence a person s decision to work pt this article considers the impact of health on the work decision of people aged 50 and over in the uk and ireland methodological issues are discussed and the impact of unobserved individual effects is estimated using the mundlak 1978 estimator applied to the multinomial probit model we find that health problems increase the probability of retirement for this age group in both countries in britain those with health problems are less likely to work full time and more likely to work pt however in ireland health problems appear to have no effect on the probability of pt work this article discusses the potential reasons for these impacts and current

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

the social security early entitlement age in a structural model of retirement and wealth abstract a structural life cycle model of retirement and wealth attributes retirement peaks at both ages 62 and 65 to social security rules and wide heterogeneity in time preferences those with high discount rates often retire at 62 they have few assets and heavily value lost benefits from working after 62 largely ignoring potential increases in later benefits declining actuarial adjustments beginning at 65 induce those with low discount rates to retire at 65 raising the social security early entitlement age to 64 induces 5 of the population to delay retiring shifting the retirement spike from 62 to 64

retirement measures in the health and retirement study this paper highlights unanswered research questions in the economics of retirement and shows how these questions can be addressed using the health and retirement study hrs unique features of the survey are described including administrative records on earnings and social security benefits and employer provided data on pensions and health insurance also collected by the survey are indicators of retirement plans health status family structure income wealth and employer policies affecting job opportunities and constraints data from the first wave of the hrs are used to analyze retirement outcomes and constraints shaping retirement behavior

crash and wait the impact of the great recession on the retirement plans of older americans this study uses data from pre and post crash surveys from the cognitive economics study to examine the impact of recent stock and labor market wealth losses on the planned retirement ages of older americans regression estimates imply that the average wealth loss between july 2008 and may june 2009 is associated with an increase in planned retirement age of approximately 2 5 months furthermore pessimism about future stock market returns is found to amplify the impact of wealth losses on retirement timing

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

changing the social security rules for work after 65 this paper simulates the effects of proposed changes in the social security rules including the elimination of the retirement earnings test for men who work after normal retirement age a policy change that was given serious consideration by the social security administration in 1988 89 and that is similar to other proposals made in congress and elsewhere since then is projected to raise long run costs by 43 billion net of taxes and to induce an increase of 3 5 in the number of full time male workers between the ages of 65 and 69 the outcome especially in the short run is greatly affected by the timing of workers decisions to apply for benefits
