The Effect of Benefit Reductions on the Retirement Age: The Heterogeneous Response of Manual and Non‐Manual Workers

I estimate the effect of benefit reductions on the timing of retirement. The introduction of actuarial adjustments in the German public pension system serves as a source of exogenous variation to estimate discrete time transition rates into retirement for individuals of age 60–66. Responses to benefit reductions are elaborated separately for manual and non‐manual workers. On average, individuals postpone retirement by 13.2 months if pension benefits are reduced by 3.6 percent for each year of early retirement. This result is in line with the previous quasi‐experimental literature and suggests that people respond to the incentive of reducing the implicit tax on further periods of work. However, among men the response is about 50 percent lower for manual workers compared to non‐manual workers. Surprisingly, this does not necessarily indicate that retirement incomes of manual workers deteriorate. The explanation is that disability pensions are available at age 63—without benefit reductions.     

我国农民工养老保障制度安排及其创新

目前,我国农民工养老保障基本上仍处于低保障状态,其原因主要在于没有形成全国统一层面的农民工养老保障制度安排,致使各地政策之间缺乏衔接,制度运行绩效较低。因此,农民工养老保障制度的构建应该坚持灵活性原则,同时兼顾效率与公平。应建立全国层面的可转移、可持续、完全积累且富有弹性的新型农民工养老保障制度,为今后实现城乡养老保障的对接创造一个良好的制度平台。     

Social insurance for the elderly

We study the effects of retirement benefits provided by social insurance programs on consumption, portfolio choice, and retirement in a continuous-time theoretical model. We show that people tend to retire earlier with an increase in retirement social insurance benefits (SIBs), consistent with empirical evidence. We show also that people tend to increase savings before retirement in anticipation of increased retirement benefits, a counter-intuitive result. The response of risky investment with an increase in the SIBs is ambiguous, depending on parameter values. The overall social welfare will increase with an increase in SIBs if the balanced budget constraint is satisfied. We also investigate the effects of changes in the two streams of the SIBs (paid in perishable goods and cash) and the proportion of workers in entire population on social welfare.     

Pension expectations,reforms and macroeconomic downturn in Italy. What can microdata tell us?

We use different years of the Bank of Italy’s Survey on Household Income and Wealth (SHIW) to explore how Italian workers’ expectations regarding their future level of pension benefits and retirement age changed from 2000 to 2014. Comparing expected and statutory values for future pension benefits and retirement ages, we find that knowledge of the pension system and its rules are not evenly distributed among workers. Some sections of the population, in particular, younger workers, women and the self-employed, are less precise in estimating their future pension benefits. As for retirement age, a large share of the working population still has not completely assimilated the implications of the linkage with the evolution of lifetime expectations at 65. Expectations in the final part of the period observed are dominated by increasing pessimism, which may be related to the macroeconomic crisis of the Italian economy and to the approval of a severe pension reform in 2011. Checking whether a household’s total wealth is consistent with lifetime consumption, we find that households where the head overestimates the future value of the pension benefit accumulate fewer resources than the remaining part of the population.     

Social Security Benefits and Employer Behavior: Evaluating Social Security Early Retirement Benefits As a Form of Unemployment Insurance

Employers often shed older workers by encouraging them to "take" early retirement. An implicit contract model suggests that this behavior will be influenced by the social security early retirement program. When demand is weak and layoffs are necessary, social security benefits can act like a form of unemployment insurance, effectively subsidizing workforce reductions by lowering the cost to the firm of shedding older workers. Since social security benefits are not subject to experience rating, the result is an inefficiently high level of early retirements. This paper concludes with a discussion of policies for restoring early retirements to efficient levels.     

Not so voluntary retirement decisions? Evidence from a pension reform

Firms may encourage their workers to retire early. Experience-rating of early retirement benefits creates incentives for firms to avoid this. We use a pension reform as a natural experiment in order to evaluate the effect of this experience-rating. The key result is that experience-rating of early retirement benefits reduces early exits of older workers.     

Tax and transfer programs,retirement behavior,and work hours over the life cycle

In this paper, we use a computable overlapping generations model economy to analyze the quantitative effects of some reforms on tax and transfer programs, aimed at easing the tax burden on the labor supply of older workers. We focus on retirement behavior, work hours over the life cycle, and efficiency gains. We find that the labor supply of older workers is very responsive to changes in tax and transfer programs and show that the gains, in terms of old-age work hours, are non-trivial. However, we also find that longer careers may not substantially increase aggregate hours because workers may reallocate labor supply over the life cycle in response to retiring later. Moreover, since longer careers may also reduce saving rates, we also find that changes in tax and transfer programs aimed at boosting the employment rates of the elderly may reduce output per head.     

Labour-incentive reforms at preretirement age in Austria

Low participation rates of older workers in the labour market threaten the sustainability of the pension system in Austria. Given the current political debate on this issue, we try to shed light on employment and retirement behaviour of Austrian couples when income support is provided and pension benefits are reduced. Using a sample of married couples with both partners aged 50–65, we find that the proposed reform increases the labour supply of middle-income men whereas the effects on women are weaker. However, somehow surprisingly, we find that these reforms have an increasing effect on unemployment/inactivity probabilities which in turn is outweighed by a decreasing effect on the retirement probabilities in case of women. These findings emphasize the importance of a joint consideration of labour supply and retirement behaviour of married couples when introducing pension reforms and tax-benefit policies.     

Social Security and Early Retirement: The Relationship Between Workers,Firms and Governments

In this paper we survey a number of theoretical and empirical studies in order to propose explanations to the fall of labour force participation at older age. Starting from the largely studied effect of social security schemes on labour supply, we explore the employers behaviour and the role of governments in the development of early retirement schemes. We show that early retirement is the result of a global agreement between firms and government where workers have incentives to early exit the labour market due to generous non actuarial benefits. Firms have an advantage to separate older workers because they are costly compared to young workers and governments hope that by pushing elderly into early retirement they will solve the massive unemployment problem.     

Social Security and Old Age Unemployment Risk with Efficient Wage Bargaining

I analyze a life‐cycle economy with old age productivity risk where wages, employment, and severance payments are set through efficient bargaining between risk averse unions and risk neutral firms. Allocations with limited union membership are second‐best inefficient as they generate too little labor supply in young age, too much consumption before retirement, too little employment of older workers (early retirement), and too little insurance against old age unemployment. Providing public transfers to early retirees (disability benefits or early pensions) might help to increase the degree of risk sharing at the cost of lower old age employment. Depending on whether absolute risk aversion is increasing or decreasing in consumption, these policies might or might not produce efficiency gains at equilibrium.     

Labor supply responses to marginal Social Security benefits: Evidence from discontinuities

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.     

Labor market shocks and retirement: Do government programs matter?

This paper argues that labor market conditions are an important and often overlooked determinant of retirement transitions. In our analysis, we examine how the unemployment rate affects retirement and whether the Social Security (SS) system and Unemployment Insurance (UI) system influence how older workers respond to labor market shocks. We use pooled cross-sectional data from the March Current Population Survey (CPS) in our analysis. We find that downturns in the labor market increase retirement transitions and that the magnitude of this effect is comparable to that associated with moderate changes in financial incentives to retire and to the threat of a health shock facing older workers. Interestingly, retirements only increase in response to an economic downturn once workers become SS-eligible, suggesting that retirement benefits may help to alleviate the income loss associated with a weak labor market. We also estimate the impact of UI generosity on retirement and find little consistent evidence of an effect. This suggests that in some ways SS may serve as a more effective form of unemployment insurance for older workers than UI.     

Welfare effects of automatic-IRAs

Several states require employers who do not offer retirement benefits to automatically enroll their employees in individual retirement accounts (IRAs). We quantify the welfare effects of this program for individuals who follow a rule-of-thumb to make savings decisions. We find workers who save more than 3% would be willing to give up 0%–1.4% of lifetime consumption to avoid an IRA. We also consider a fully rational model with credit frictions, stochastic income and pre-retirement withdrawals, and costly IRA opt-outs. We find that being enrolled in an IRA is most likely to benefit workers who do not borrow during the life-cycle.     

Equilibrium unemployment and retirement

We first propose some new empirical evidence on the fact that the labor market conditions matter for the retirement decision at the individual level: we investigate whether unemployed workers retire before employed workers, other things being equal. Our main objective in this paper is then to propose an equilibrium unemployment approach to retirement decisions that allows us to derive the positive and normative features of retirement decisions when search and matching frictions are considered. Two main conclusions emerge: the retirement decision of unemployed workers depends on the labor-market frictions whereas that of employed workers does not; the existence of search externalities makes the retirement age of unemployed workers intrinsically suboptimal. Considering Social Security policy issues, we show that the complete elimination of the implicit tax on continued activity is not necessarily welfare-optimizing in a second best world where the labor market equilibrium suffers from distortions.     

Reinforcing the Link Between Contributions and Pensions: The Effect of the Population Aging

In this paper, we analyze a majority voting process on the earnings-related part of pension benefits in a Social Security system with flexible retirement. We show that the aging of the population may make it easier to implement one of the proposed reforms to achieve a delay in the average retirement age of workers, to reinforce the link between contributions and pensions.     

Spatial incentives to coordinate contiguous habitat

This paper discusses a series of economic experiments designed to explore whether a set of conservation subsidies—called the agglomeration bonus—can induce a socially optimal spatial pattern of conservation given landowner land retirement decisions are voluntary. The novelty of our approach is the use of the agglomeration bonus idea which depends on explicit topological relationships between a unit of conserved land and its neighboring conserved land; specifically, subsidies paid when one conserved land unit borders other conserved units. The agglomeration bonus approach is refined by providing a menu of subsidies and penalties that can used to encourage particular patterns of land preservation voluntarily. Our results suggest the agglomeration bonus—once our subjects gain experience with coordination—can achieve the specific contiguous land preservation pattern that was targeted.

Estimating the social cost of pesticide use: An assessment from acute poisoning in Brazil

The intensive use of pesticides in countries like Brazil has ignored structural and institutional shortfalls, such as the lack of workforce training for the new, difficult to implement technologies, and the institutional vulnerability of the environmental protection, health, and safety sectors. As a result we have “invisible” or social, environmental and health costs which end up being socialised with the farmer, in general, having no incentives to recognise and internalise them. This study is intended to review and develop this problem in the light of the Brazilian reality. To this end, we make use of an empirical exercise to illustrate estimation of the social cost associated with acute poisoning by pesticide using the PREVS/IBGE data (Harvest Forecast Research) in the state of Paraná, Brazil. The results suggest that, for maize, the costs of acute poisoning could represent 64% of the benefits of using herbicides and insecticides, and, in the best of hypotheses, when some risk factors are eliminated, they may reach 8% of the benefits of the use of these products. Similarly, when we examine future scenarios for five and ten years, we find less encouraging results, as in ten years the costs of acute poisoning could reach around 85% of the benefit of using insecticides and herbicides for maize. However, there is the encouraging news that, if preventive measures were taken during this time, the gains would be considerable, about 6.5 times greater. We conclude that an assessment of the real benefits involved with pesticides in Brazil is required, principally in regard to the smallholder, where farmers need more training in the use — or even the elimination — of these hazardous substances. There are sustainable technological options available which are economically efficient, especially if we consider the social, environmental and health costs. In this context it is worth highlighting the role of regulatory measures as a mechanism which can reorient generation of negative external costs through the reduction of current incentives in the socialisation of private costs.     

Phasing out: Routine tasks and retirement

This paper studies the link between task content of jobs and exits to retirement by older workers. This research provides a comparative analysis of retirement timing in Germany and Great Britain. In Germany, workers in more routine jobs had between one and two percentage points higher probability leaving the labor market faster when compared to workers in less routine occupations. The relationship is robust and relatively constant over time. In Great Britain, by contrast, workers from routine and non-routine jobs appear to leave the labor market with a similar timing. I contend that institutional characteristics can explain the differences across countries.     

人口年龄结构对农村居民消费的影响研究——以浙江省为例

以生命周期假说为依据,通过引入人口年龄结构因素,构建了消费理论模型;利用2003~2011年的浙江省地市级面板数据,考察了少儿人口抚养比、老年人口抚养比与农村居民消费之间的关系。实证结果表明,少儿人口抚养比对农村居民消费呈显著的负向作用,少儿人口抚养比每增加1个单位,消费将平均减少0.044%;老年人口抚养比对农村居民消费呈显著的正向作用,老年人口抚养比每增加1个单位,消费将平均增加0.76%。当前浙江省少儿人口抚养比呈递减态势,而老年人口抚养比则呈递增态势,两者协同促进了农村居民的消费。
