economic and spatial effects of land value taxation in an urban area an urban computable general equilibrium approach this paper studies the effects of switching from a capital property tax to a land value tax using an urban computable general equilibrium model calibrated to the features of the atlanta georgia area our model differs from prior simulation studies in that we assume that residents own a fixed amount of land rather than assuming an absentee landowner we consider three income groups rather than just one we consider cases in which housing capital is not completely mobile and we allow for a labor leisure choice

policy uncertainty and household savings using german microdata and a quasi natural experiment we provide evidence on how households respond to an increase in uncertainty we find that household saving increases significantly following the increase in political uncertainty observed in the run up to the 1998 german general election we also find evidence of a labor supply response by workers who can use the margin offered by part time employment our results are suggestive of the economic effects of wars of attrition when political disagreement leads to delays in adopting a reform or the possibility that earlier reforms may be revoked the increased uncertainty could slow the economy

the illusion of fiscal illusion unsticking the flypaper effect recognizing that it is difficult to prove a negative this paper marshals evidence in support of the hypothesis that the widely documented flypaper effect of federal grants to state and local governments is purely a statistical artifact a review of previous studies and a monte carlo investigation suggest that the use of an inappropriate functional form may generate an illusory flypaper effect a local expenditure equation is then estimated in alternative specifications with ten years of state level data empirical results confirm the sensitivity of the flypaper effect to specification and tests of fit unambiguously favor one functional form that specification yields no statistical evidence of a flypaper effect

reforming taxes and raising revenue part of the fiscal solution this paper reviews the fiscal outlook in the united states discusses why revenue increases are a critical aspect of any enduring fiscal solution and outlines constructive policies to reform the tax system and simultaneously raise revenues in particular this paper highlights the merits of curtailing income tax expenditures introducing a value added tax and imposing levies on consumption and production of non renewable energy copyright 2011 oxford university press

are contributions to public pension programmes a tax on employment many studies describe the potentially adverse impact on employment of the payroll costs of financing public pension programmes conventionally empirical studies treat contributions to public pension programmes as a pure tax in for example calculations of the tax wedge by oecd but this approach ignores any future rights to benefits that are perceived by contributors in fact public pension programmes contain both an actuarial and a redistributive component the former closer to saving the latter a tax the paper constructs indicators of the tax component of pension programmes both between and within generations across a range of oecd countries and time periods it uses these measures in a cross country panel analysis of the determinants of age and gender specific economic activity rates the results reveal robust evidence that when public pension programme contributions are broken down into a tax component and a savings component the tax component of the payroll contribution reduces economic activity rates among women while a higher retirement saving component has the opposite effect there is little evidence that average tax rates however constructed have any adverse impact on the economic activity rates of men richard disney

public policy and saving in the united states and canada canadians have largely unrestricted access to tax preferred saving through the registered retirement saving plan rrsp programs no comparable program exists in the united states previous research has noted that household saving in canada grew relative to saving in the united states after the rrsp program was initiated suggesting that a program like the rrsp can increase saving this paper shows that the difference in household saving in the united states and in canada is more plausibly characterized as a simple life cycle response to differences in the overall intertemporal income reallocation built into tax and public pension systems rather than as a response to rrsp availability

risk pooling along a fixed delivery route using a dynamic inventory allocation policy this paper examines static and dynamic policies for replenishing and allocating inventories amongst n retailers located along a fixed delivery route each retailer faces independent normally distributed period demand and incurs a proportional holding or backorder cost on end of period net inventory a warehouse places a system replenishment order every m periods which is received after a fixed leadtime of t periods immediately upon receipt a delivery vehicle leaves the warehouse with the system replenishment quantity and travels to the retailers along a fixed route with fixed leadtimes between successive retailers the warehouse holds no inventory under the static policy allocations are determined for all retailers simultaneously at the moment the delivery vehicle leaves the warehouse under the dynamic policy allocations are determined sequentially upon arrival of the delivery vehicle at each retailer our major analytical results under appropriate dynamic static allocation assumptions are 1 optimal allocations under each policy involve bringing each retailer s normalized inventory to a corresponing normalized system inventory 2 optimal system replenishments are base stock policies 3 the minimum expected cost per cycle of dynamic static policy can be derived from an equivalent dynamic static composite retailer given this we prove that the risk pooling incentive a simple measure of the benefit from adopting dynamic allocation policies is always positive our simulation tests confirm that dynamic allocation policies yield lower costs than static policies regardless of whether or not their respective allocation assumptions are valid however the magnitude of the cost savings is very sensitive to some system parameters

saving puzzles and saving policies in the united states in the past two decades the widely reported personal saving rate in the united states has dropped from double digits to below zero first we attempt to account for the decline in the national income and product accounts nipa saving rate the macroeconomic literature suggests that 40 50 per cent of the drop since 1988 can be attributed to households spending stock market capital gains another 30 per cent is accounting transfers from personal saving into government and corporate saving because of the way pensions and capital gains taxes are treated in the nipa second while nipa saving measures are well suited to measuring the supply of new funds for investment and capital accumulation it is not clear that they should be the target of government saving policies finally we emphasize that the nipa saving rate is not useful in judging whether households are preparing for retirement or other contingencies many households have accumulated significant wealth primarily through retirement saving vehicles and capital gains even as the saving rate slid there remains a segment of the population who save little and whose behaviour appears untouched either by the stock market boom or the slide in personal saving we explore reasons and policy options for their puzzling low saving rate copyright 2001 oxford university press

do tax incentives for saving in pension accounts cause debt accumulation evidence from danish register data abstract this paper applies a quasi experimental research design on a danish 2010 policy that reduced tax incentives for saving in annuity pension schemes to show significant substitution of savings from retirement accounts to gross debt repayments we find that for every 1 danish currency unit reduction in retirement savings 31 cents goes to debt repayments taking into account all types of savings we find full crowding out consistent with previous findings we document that the effect is driven by a minority about 23 percent who actively rebalance their savings

pension wealth and household saving evidence from pension reforms in the united kingdom using three major u k pension reforms as natural experiments we investigate the relationship between pension saving and discretionary private savings unlike most differences in differences approaches which rely on average differences between control and treatment group we use economic theory to model the response of each individual household the empirical analysis based on the family expenditure survey uses both time series and cross sectional variation to identify the behavioral response the earnings related tier of the pension scheme is found to have a negative impact on private savings with relatively high substitution elasticities the impact of the flat rate tier is not significantly different from zero jel h55 h91 the relationship between pension wealth and household savings is crucial for important policy issues such as establishing the effects of changes in pension legislation on saving behavior from a theoretical point of view the lifecycle framework suggests that the provision of public benefits after retirement constitutes a negative incentive to accumulate wealth during one s working life quantifying the resulting relationship between pension wealth and saving even within a simple theoretical frame

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

tax reform and automatic stabilization an income tax provides implicit insurance by dampening the variability of disposable income and consumption using an empirical framework derived from the consumption insurance literature and data from the panel study of income dynamics we examine the effect of federal income tax reforms of the 1980 s on automatic stabilization of consumption overall erta and tra86 reduced consumption stability by about 50 percent recently increased eitc generosity restored or enhanced consumption insurance the welfare cost of moving to the post tra86 system is sizable for relatively risk averse households facing large income risk but is much more modest for the typical household jel h21

lessons from the u s unemployment insurance experiments recent social experiments have evaluated two reforms of the unemployment insurance ui system reemployment bonuses and job search programs the bonus experiments show that economic incentives affect the length of ui receipt and provide weak evidence that an earlier return to work does not decrease earnings the experiments do not show the favorability of a permanent bonus program as they ignore its effect on the number of the claimants the job search experiments test several more promising reforms nearly all of the combinations of services and increased enforcement reduce ui receipt and have favorable cost benefit analyses earnings often increase though the estimates are imprecise

the effects of public pensions on private wealth evidence on the german savings puzzle based on german panel data between 1984 and 1999 we test for the interaction of social security benefits and private wealth formation in a simple life cylce model benefits from public pension systems should displace equal amounts of private retirement accumulation our estimate for the offset effect corrected for several possible measurement biases is much lower however than expected from pure life cycle considerations and less than comparable estimates for the us and the uk this result thus supports other evidence on a particular german savings puzzle which might be due to market imperfections and or bounded rational behaviour

disentangling retirement and savings responses in january 2006 the dutch government implemented a pension reform that substantially reduced the public pension wealth of workers born in 1950 or later at the same time a tax facilitated savings plan was introduced that implied a large savings subsidy for all workers irrespective of birth year this paper uses linked administrative and survey data to assess the effect of the reform on the savings and retirement expectations and realizations of two virtually identical male cohorts that differ only in treatment status the treated having been born in 1950 and the controls having been born in 1949 we show that retirement expectations are in line with realizations and that the reform increased the labor supply for the larger part of the workers namely those without sufficient means to substantially increase private savings to counter the effect of the reform these workers have zero substitution rates between private and public wealth on the other hand there is a group of mostly high wage workers who participate in the tax facilitated savings plan and increase their private savings to fully counter the impact of the drop in public wealth an unintended side effect of the introduction of the tax facilitated savings plan is that high wage earners who are not affected by the drop in pension wealth retire even sooner than initially planned

the nature of precautionary wealth abstract this paper uses the panel study of income dynamics to provide some of the first direct evidence that wealth is systematically higher for consumers with predictably greater income uncertainty however the apparent pattern of precautionary wealth is not consistent with a standard parameterization of the life cucle model in which consumers are patient enough to begin saving for retirement early in life wealth is estimated to be far less sensitive to uncertainty than implied by that model instead our results suggest that over most of their working life time consumers behave in accordance with the buffer stock models of saving described in carroll 1992 1997 or deaton 1991 in which consumers hold wealth principally to insulate consumption against near term fluctuations in income

exact and approximate cost functions for product aggregates we show that certain large multiproduct problems can be well approximated by smaller models of the same form representing only one aggregate product or a few such products this reduction follows from a new technique to approximate the minimal cost of a special allocation or disaggregation problem by a simple closed form aggregate cost function this function moreover has the same form as the cost functions for the original individual products for special cases the approximation is exact this latter result is related to economic theoretic research on aggregation with homothetic preferences the results are applied to a one stage multiperiod multi item production smoothing model and then to a similar model of a two stage system yielding a reduction in the number of items to one or to relatively few

pension coverage and retirement savings of young and prime aged workers in canada 1986 1997 in this paper we assemble data from several household surveys to document how pension coverage of young and prime aged workers has evolved in canada between the mid 1980s and the mid 1990s we show that between 1986 and 1997 pension coverage has fallen significantly for men has dropped slightly for young women and has increased for prime aged women the decline in union density and employment shifts towards low coverage industries explain most of the decline in pension coverage of men and young women in contrast most of the increase in coverage of prime aged women remains unexplained while pension coverage has fallen for men and young women their real average contributions to registered retirement savings plan rrsps have increased substantially as a result the sum of the amounts they contributed to registered pension plans rpps and rrsps has increased markedly jel classification j26 j32 couverture des regimes de rentes et epargnes pour la retraite des travailleurs jeunes et de ceux dans la force de l ge au canada 1986 1997 dans ce memoire les auteurs assemblent des donnees de plusieurs enquetes sur les menages pour documenter l evolution de la couverture des regimes de rentes des travailleurs jeunes et dans la force de l ge entre le milieu des annees 80 et le milieu des annees 90 on montre que cette couverture a chute de maniere significative pour les hommes a decline legerement pour les femmes et s est accrue pour les femmes dans la force de l ge la chute du taux de syndicalisation et les deplacements de l emploi vers des secteurs ou la couverture est plus faible expliquent le gros du declin de couverture pour les hommes et les jeunes femmes quant a l accroissement de la couverture pour les femmes dans la force de l ge il demeure inexplique alors que la couverture des deux premiers groupes a decline leurs contributions aux regimes enregistres d epargne retraite reer ont augmente substantiellement en consequence le total des sommes qu ils ont contribuees aux regimes de rentes enregistres et aux reer ont augmente de maniere importante

savings in times of demographic change lessons from the german experience pension reforms in many developed countries make individuals shoulder a bigger share of longevity and income risks the desired response is that individuals accumulate private assets for retirement whether this actually takes place is of paramount relevance for scientists and policy makers we take germany as an example twenty years of pension reform have transformed the monolithic german pension system into a multi pillar system formerly generous public pension benefits are gradually being reduced while substantial incentives are granted to occupational and private saving schemes has this transition worked out we survey the reform steps and household s reactions how did individuals adjust their labor market behavior how did private and occupational pension plans take off how do behavioral adjustments vary in the population most germans adapted to the new situation both actual and expected retirement decisions changedand the share of households without supplementary pensions decreased from 73 to 39 in little more than a decade this is a remarkable success nonetheless households with low education low income and less financial education did neither adjust their retirement behavior nor pick up supplementary pension plans and are thus likely to face difficulties in bridging the gap arising in future pension income

the level and distribution of global household wealth the level of average household wealth in all countries is estimated via the determinants of assets and debts for 39 countries which have balance sheet or survey data the distribution of wealth in all countries is inferred from information on the pattern of wealth ownership for 20 countries covering 59 of world population combining the level and distribution figures suggests that median global wealth was ppp 8 635 in the year 2000 and that ppp 518 361 was needed to belong to the top percentile the top decile owned 71 of world wealth and the global gini value was 0 802

population policies demographic structural changes and the chinese household saving puzzle abstract using combined data from population censuses and urban household surveys we study the effects of demographic structural changes on the rise of household savings in china variations in fines across provinces for unauthorized births under the one child policy and in cohort specific fertility influenced by the implementation of population control policies are exploited to facilitate identification we find evidence that older households with fewer adult children saved more middle aged households with fewer dependent children experienced increase in savings and younger households with fewer siblings also saved more these findings lend support to a simple economic model in which the effects of population control policies are investigated in the context of household saving decisions in china

have iras increased u s saving evidence from consumer expenditure surveys the vast majority of individual retirement account contributions represent net new saving based on evidence from the quarterly consumer expenditure surveys ces the results are based on analysis of the relationship between ira contributions and other financial asset saving the data show almost no substitution of iras for other saving estimates are based on a flexible constrained optimization model with the ira limit the principal constraint the implications of this model for saving in the absence of the ira option match very closely the actual non ira financial asset saving behavior prior to 1982 ira saving does not show up as other financial asset saving in the pre ira period

political economy of pension plans impact of institutions gender and culture abstract national pension systems are an important part of financial intermediation and worker welfare in most countries but how and why do they differ internationally controlling for important political economic and social institutions we document that international differences in pension progressivity or how pensions reflect lifetime earnings are negatively related to masculinity uncertainty avoidance individualism long term orientation employment rights average pension levels social trust and economic inequality we also find that pension progressivity is positively related to the economic and societal role of women the extent of catholicism as well as political voice and accountability these results provide important insights for both public policy and mnc managers

the role of intergenerational transfers and life cycle saving in the accumulation of wealth he purpose of this paper is to review what economists know at present about the following question how large a portion of the existing wealth is the result of a bequest motive that is of accumulation for the specific purpose of leaving bequests i will also endeavor to clarify why an answer to this question is of interest in the early keynesian period when the study of national saving first attracted wide interest relatively little attention was paid to what led people to save though it was generally understood that the main systematic reason was to leave bequests j m keynes in the famous chapter 9 of the general theory of employment interest and money 1936 had listed seven distinct motives for saving besides the leaving of bequests but five of these which include to increase one s future income or to insure one s independence and power implied that all or nearly all the accumulation would finally wind up as bequeathed wealth this in turn meant that most private wealth originated through bequests that is it either had been received through bequests or was destined to be bequeathed and indeed how else could society accumulate wealth however keynes 1936 p 107 also mentioned two further motives precaution that is to build up a reserve against unforeseen contingencies and foresight that is to provide for an anticipated future relation between the income and the needs of the individual or his family different from that which exists in the present as for example in relation to old age family education or the maintenance of dependents these motives in contrast to most of the previous ones have the

intergenerational transfers and capital market imperfections evidence from a cross section of italian households abstract we investigate whether a system of family finance exists and to what extent it is able to offset capital market imperfections a simple model of intergenerational transfers implies that the probability of a liquidity constrained consumer receiving a transfer is negatively correlated with his current endowment and positively correlated with his future resources we test this proposition using a recent survey of italian households in which both transfer recipients and liquidity constrained households are readily observable the results indicate that private transfers help to ease borrowing constraints however a substantial number of liquidity constrained households remain after transfers have been made

dynamic balancing of inventory in supply chains abstract we consider the dynamic version of the classic problem of allocation of inventories to a set of retailers to rectify the imbalance of inventories amongst them while most research is focussed on analyzing different allocation strategies with a predetermined time of shipment static policy we investigate the benefit of using real time demand inventory information to schedule rebalancing shipments in a retail network we model the dynamic rebalancing problem that has two decisions the timing of the balancing shipments and determination of the new stocking levels at the retailers as a dynamic program dp we obtain structural properties for the optimal allocation rebalancing and timing strategies we also present conditions under which a greedy heuristic to decide how much to ship from one retailer to another is optimal the dp for determining the optimal timing and quantity of shipments has a very large state space we present an algorithm to solve this dp efficiently we also provide a heuristic solution procedure to the dynamic problem that performs very close to optimal numerical results show that dynamic allocation policies can lead to substantial benefits over the static policy especially in systems in which the starting inventories at the retailers are balanced or when high service levels are required

how strong are bequest motives evidence based on estimates of the demand for life insurance and annuities this paper presents new empirical evidence in support of the view that a significant fraction of total saving is motivated by the desire to leave bequests specifically i find that social security annuity benefits significantly raise life insurance holdings and depress private annuity holdings among elderly individuals these patterns indicate that the typical household would choose to maintain a positive fraction of its resources in bequeathable forms even if insurance markets were perfect evidence on the relationship between insurance purchases and total resources reinforces this conclusion

a welfare analysis of social security in a dynastic framework in this article we study the welfare effects of unfunded social security in a general equilibrium model populated with overlapping generations of altruistic individuals that differ in lifetime expectancy and earnings ability contrary to previous research our results indicate that steady state welfare increases with social security for most households although by very different amounts this result is mainly due to two factors first the presence of two sided altruism significantly mitigates the crowding out effect of unfunded social security second ability shocks and uncertain lifetimes generate significant heterogeneity among households to yield different induced preferences for social security

on five hot issues on wealth distribution throughout the last twenty years a lot of attention has been devoted by economists to the accumulation and distribution of wealth it appears clearly that we are now quite rich in hypotheses and models but still very poor in data this brief paper will focus on five hot issues on the distribution of wealth 1 is wealth inequality mainly due to income differences 2 what is the quantitative importance of inheritance on wealth accumulation and inequality 3 is equal sharing an egalitarian rule 4 do consumers segmentation or assets distinction help understanding wealth distribution 5 is there a long term increase or decrease of the strikingly similar degree of wealth inequality among industrialized countries

the impact of pension schemes on saving in israel israeli micro and macro data indicate that consumption smoothing is limited and thus pension savings increase private and national savings since private savings rates are to a great extent unequal across different income groups saving is almost exclusively concentrated in the upper two quintiles

savings the policy debate in europe thre issues dominate the public policy debate over savings in continental europe first can private savings substitute for public pensions in the provision of retirement income given that the current generosity of pay as you go financed pensions is hardly sustainable in the light of population ageing and if so which policy steps have to be taken to alleviate this transition second does the evolution of a new financial landscape in europe necessitate policy response in terms of taxation and regulation specifically considering the increase in pension funds and third closely related to the other two issues is there too much or too little saving in an ageing europe do we need to subsidise saving more or less than we currently do the paper reviews economic theory and empirical evidence on these intertwinded issues most importantly it identifies many gaps in our theoretical and empirical knowledge that caution us against overly strong policy recommendations

a head to head comparison of augmented wealth in germany and the united states we examine the composition of augmented household wealth i e the sum of net worth and pension wealth in the united states and germany pension wealth makes up a considerable portion of household wealth of about 48 percent in the united states and 61 percent in germany when pension wealth is included in household wealth the gini coefficient falls from 0 889 to 0 700 in the united states and from 0 755 to 0 508 in germany if the wealth shares in germany were the same as in the united states this would lead to a 12 6 percent increase in the gini coefficient in the augmented wealth distribution in germany

pension wealth and household savings tests of robustness abstract a substantial literature exists on the impact of pension schemes both public and private on the level of household saving yet there is no clear consensus on the impact of pensions on private saving in this paper we show how beliefs about this displacement effect are modified by prior beliefs both about variables which might be relevant in an equation for private savings and about the magnitude of the displacement effect using data for 8279 canadian households and estimates of pension wealth both private and social security which we construct for each household in the sample the estimated displacement effects are found to be relatively robust with respect to both types of prior belief

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

state and local impacts of a revenue neutral shift from a uniform property to a land value tax results of a simulation study this paper reports on the results of simulating a revenue neutral shift from a statewide uniform property tax to a land value tax the statewide economic impacts of such a tax reform are projected to be generally positive and also persistent in a state like new hampshire however substantial variations in those impacts among the state s counties could be expected to occur

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

approximations of dynamic multilocation production and inventory problems consider a central depot or plant which supplies several locations experiencing random demands orders are placed or production is initiated periodically by the depot the order arrives after a fixed lead time and is then allocated among the several locations the depot itself does not hold inventory the allocations are finally received at the demand points after another lag unfilled demand at each location is backordered linear costs are incurred at each location for holding inventory and for backorders also costs are assessed for orders placed by the depot the object is to minimize the expected total cost of the system over a finite number of time periods this system gives rise to a dynamic program with a state space of very large dimension we show that this model can be systematically approximated by a single location inventory problem all the qualitative and quantitative results for such problems can then be applied

crowd out education and employer contributions to workplace pensions evidence from canadian tax records this study assesses whether workplace pensions help individuals overcome knowledge barriers to saving for retirement using administrative data from canada and exploiting unique features of the pension system i find compelling evidence that each 1 contributed to workplace pensions partially crowds out other retirement saving by approximately 0 50 among interior savers in a regression kink design centering on unionized workers for methodological reasons further analysis indicates active versus passive decisions are influenced by education exploiting compulsory schooling reforms for identification i conclude by showing pension and education reform are both viable mechanisms for boosting saving from a life cycle perspective jel codes e21 h30 i21 j32

why do most italian youths live with their parents intergenerational transfers and household structure more than 80 of italian men aged 18 30 live with their parents we argue that one contributing factor to this remarkably high rate of cohabitation is parents tastes for co residence in order to investigate the role of parental preferences we estimate the effect of exogenous changes in parental income on rates of cohabitation in italy using shiw micro data from 1989 to 2000 the key econometric issue is the potential endogeneity of parental income in order to identify a source of exogenous variation in parental income we use changes in fathers retirement age induced by the 1992 reform of the italian social security system as an instrumental variable for parental income by raising retirement age this reform forced some fathers to remain in the labour market longer than they would have otherwise therefore raising their disposable income we use a two sample instrumental variable tsiv strategy our tsiv estimates indicate that a rise in parents income significantly raises the children s propensity to live at home a 10 increase in annual parental income results in approximately a 10 rise in the proportion of boys living with their parents although we cannot definitely rule out alternative interpretations these results are consistent with our hypothesis that cohabitation is a normal good for italian parents

motor fuel taxation energy conservation and economic development a regional approach abstract combustion of motor fuels has a variety of environmental impacts on local regional and global scales taxing motor fuels more heavily would mitigate those environmental impacts however many governments are reluctant to increase motor fuel taxes because they fear that the tax incidence will be regressive and that economic development will be impeded using data for the new england region of the united states this paper argues that an oil importing region can conserve energy avoid regressive impacts and encourage economic development by taxing motor fuels more heavily and rebating the incremental revenues to owners of motor vehicles

pensions and household wealth accumulation abstract economists have long suggested that higher private pension benefits crowd out other sources of household wealth accumulation we exploit detailed information on pensions and lifetime earnings for older workers in the 1992 wave of the health and retirement study and employ an instrumental variable iv identification strategy to estimate crowd out the iv estimates suggest statistically significant crowd out each dollar of pension wealth is associated with a 53 67 cent decline in nonpension wealth with less precision we use an instrumental variable quantile regression estimator and find that most of the effect is concentrated in the upper quantiles of the wealth distribution

health spending and public pension evidence from panel data abstractthis article empirically investigates the determinants of aggregate health expenditure in a panel of oecd countries from 1980 to 2005 we differ from most existing studies by testing some new determinants motivated by recent theoretical advances in the literature we find that a one percentage increase in public pension payments per elderly person leads to approximately a one third percentage increase in aggregate health spending and this effect is significant and robust across a variety of model specifications a back of the envelope calculation based on this estimate suggests that the expansion of the public pension programme on average accounts for approximately over one fifth of the rise in aggregate health expenditure as a share of gdp in the set of oecd countries during 1980 2005 in addition we find that the estimated effect of gdp per capita in our model ranges from 0 66 to 0 80 which is consistent with the results from some recent studies and thus further reinforces the finding in the

labor supply elasticity and social security reform abstract previous literature on social security reform has used a variety of period utility functions and calibrated values for the intertemporal elasticity of substitution ies in labor in this paper we show that the effects of social security reforms on aggregate labor supply are invariant to plausible values of the ies but the effect of such reforms on the profile of hours over the life cycle is highly sensitive to the ies we first establish these results analytically in a simple partial equilibrium setting and then demonstrate their robustness in a general equilibrium model calibrated to match key u s macroeconomic indicators we find that the aggregate effects are similar regardless of the wide range of the values of ies used in calibrated economies however social security reform leads to a large reallocation of hours worked over the life cycle from early years to later working years and the size of this reallocation significantly increases with the ies

understanding domestic savings an empirical approach abstractthere are two unusual and important features in the evolution of the savings rate in chile first the economy increased the average savings rate by 11 percentage points in the period 1985

implications of a land value tax with error in assessed values land value taxation has numerous potential advantages compared to conventional property taxes on capital and land the models that establish these advantages however are grounded in the unlikely assumption that land values are assessed without error this paper demonstrates that levying taxes based on land values assessed with error is equivalent to the application of one tax rate to the true value of land and a different effective tax rate to capital the model demonstrates that a land value tax will have at most the distortion effects of a property tax even with the worst possible land value assessment errors

aching to retire the rise in the full retirement age and its impact on the social security disability rolls abstract the social security amendments of 1983 reduced the generosity of social security retired worker benefits in the u s by increasing the program s full retirement age from 65 to 67 and increasing the penalty for claiming benefits at the early retirement age of 62 these changes were phased in gradually so that individuals born in or before 1937 were unaffected and those born in 1960 or later were fully affected no corresponding changes were made to the program s disabled worker benefits and thus the relative generosity of social security disability insurance ssdi benefits increased in this paper we investigate the effect of the amendments on ssdi enrollment by exploiting variation across birth cohorts in the policy induced reduction in the present value of retired worker benefits our findings indicate that the amendments significantly increased ssdi enrollment since 1983 with an additional 0 6 of men and 0 9 of women between the ages of 45 and 64 receiving ssdi benefits in 2005 as a result of the changes our results further indicate that these effects will continue to increase during the next two decades as those fully exposed to the reduction in retirement benefit generosity reach their fifties and early sixties

a multiechelon inventory model with fixed replenishment intervals this paper develops a new model for studying multiechelon inventory systems with stochastic demand for the model we assume that each site in the system orders at preset times according to an order up to policy that delivery times are deterministic and that the demand processes are stochastic with independent increments we introduce a new scheme for allocating stock in short supply which we call virtual allocation and which permits significant tractability we exercise the model on a set of test problems for two echelon systems to get insight into the structure of good policies the primary findings are that both the central warehouse upper echelon and the retail sites lower echelon should hold safety stock but that most of the safety stock should be at the retail sites consequently the central warehouse will stock out with high probability furthermore we show that the virtual allocation rule is near optimal for the set of test problems

what accounts for the variation in retirement wealth among u s households even among households with similar socioeconomic characteristics saving and wealth vary considerably life cycle models attribute this variation to differences in time preference rates risk tolerance exposure to uncertainty relative tastes for work and leisure at advanced ages and income replacement rates these factors have testable implications concerning the relation between accumulated wealth and the shape of the consumption profile using the panel study of income dynamics and the consumer expenditure survey we find little support for these implications the data are instead consistent with rule of thumb mental accounting or hyperbolic discounting theories of wealth accumulation jel di d91 e21

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

the consumption and wealth effects of an unanticipated change in lifetime resources in 2000 italy replaced its traditional system of severance pay for public employees with a new system under the old regime severance pay was proportional to the final salary before retirement under the new regime it is proportional to lifetime earnings this reform entails substantial losses for future generations of public employees in the range of 20 000 30 000 depending on seniority using a difference in difference framework we estimate the impact of this unanticipated change in lifetime resources on the current consumption and wealth accumulation of employees affected by the reform in line with theoretical simulations we find that each euro reduction in severance pay reduces the average propensity to consume by 3 cents and increases the wealth income ratio by 0 32 the response is stronger for younger workers and for households where both spouses are public sector employees this paper was accepted by amit seru finance

social security and households saving this paper provides new evidence on the substitutability between private and pension wealth by exploiting the italian pension reform of 1992 we use a difference in difference estimator that exploits the differential effects of the reform on individuals belonging to several yea of birth cohorts and different occupational groups we find convincing evidence that saving rates increase as a result of a reduction in pension wealth by allowing for the possibility that substitutability changes with age we find that substitutability is particularly high and precisely estimated for workers between 35 and 45

iras and household saving this paper examines the effects of individual retirement accounts iras on private and national saving the authors construct a formal model of dynamic utility maximization that generates closed form equations for ira and other saving their empirical estimates indicate that raising the annual ira contribution limit between 1983 and 1986 would have resulted in little if any increase in national saving results from sensitivity analysis imply substantially smaller effects on national saving than most previous researchers have estimated the authors results are consistent with new evidence they present indicating considerable potential among ira holders to shift taxable forms of saving into iras copyright 1994 by american economic association

declining public pensions in an era of demographic ageing will private provision fill the gap abstract demographic crisis and imprudent commitments have induced a crisis in public pension programmes in oecd countries will present and prospective cutbacks lead to greater private saving either in the form of private pension provision or in other forms of saving the paper surveys existing evidence and provides new results on three questions do individuals substitute private for public provision of savings when public pension programmes are cut back voluntarily do individuals respond to incentives to join sponsored or tax subsidised arrangements if encouraged by the government and if individuals are prepared to make such arrangements and where saving is voluntary do they save enough to replace previous prospective public pension flows

retirement expectations pension reforms and their impact on private wealth accumulation abstract we estimate the effect of pension reforms on households expectations of retirement outcomes and private wealth accumulation decisions exploiting a decade of intense italian pension reforms as a source of exogenous variation in expected pension wealth the survey of household income and wealth a large random sample of the italian population elicits expectations of the age at which workers expect to retire and of the ratio of pension benefits to pre retirement income between 1989 and 2002 we find that workers have revised expectations in the direction suggested by the reform and that there is substantial offset between private wealth and perceived pension wealth particularly by workers that are better informed about their pension wealth

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

pension wealth and individual saving some new evidence attemprs to measure the tmpact of soctal security and private pensions on household saving have occupied much of the literature in empirical public finance over the past decade empirical estimates of those impacts have been quite varied see the discussion in aaron 1982 this paper provides new estimates of the impact of changes in holdings of social security and private pension annuities on the level of non pension wealth the data examined are drawn from surveys conducted for the u s president s commission on pension policy the impact of the social security system on individual saving has been a concern since feldstein s 1974 pioneering paper l the theoretical argument of feldstein and of barro 1974 1978 centers around the funding status of social security i e the degree to which an unfunded social security system reduces private saving empirical tests of the effects of social security on saving in this line of research have been conducted in the perfect certainty version of the life cycle model modigliani and ando 1957 modigliani and brumberg 1954 in that approach social security affects non pension saving through its impact on individual intertemporal budget constraints disposable income during the working period falls by the amount of

pension reform and saving in britain the paper examines the pension programme in britain focusing on reforms that have increased the fraction of the work force opting out of public provision and that have permitted individuals to choose their private pension provider it also examines the issue of pension provision and household saving the paper highlights the disparities in retirement saving behaviour across types of pension provision and different households the paper discusses the policy issues of the adequacy of household saving and the impact of pension reform on household saving and the public finances

is pension reform conducive to higher saving declining fertility mortality and productivity rates in developed countries and the popularity of the social security privatization in chile as a pathway to financial development have sparked a global interest in social security reform this paper analyzes the effect of social security on saving using a panel of countries over 25 years variation in the characteristics of social security systems is used to determine whether less reliance on a pay as you go unfunded system is associated with higher national saving there is little evidence that countries that implement defined contribution reforms have higher trends in saving rates after the reform cross sectionally countries with pay as you go systems tend to have lower saving rates and this effect increases with the coverage rate on the system

pension wealth and household savings in europe evidence from sharelife we use recently collected retrospective survey data to estimate the displacement effect of pension wealth on household savings the third wave of the survey of health ageing and retirement in europe sharelife collects information on the entire job history of the respondent a feature missing in most previous studies we show that addressing measurement error problems is crucial to estimate the displacement effect when using survey data we find that each euro of pension wealth is associated with a 47 61 cent decline in non pension wealth using robust median regression in the presence of biases from measurement errors and omitted unobserved variables we estimate a lower bound to the true offset between 17 and 30 significantly different from zero instrumental variables regression estimates although less precise suggest full displacement
