We argue that US welfare would rise if unemployment insurance were increased for younger and decreased for older workers. This is because the young tend to lack the means to smooth consumption during unemployment and want jobs to accumulate high-return human capital. So unemployment insurance is most valuable to them, while moral hazard is mild. By calibrating a life cycle model with unemployment risk and endogenous search effort, we find that allowing unemployment replacement rates to decline with age yields sizeable welfare gains to US workers.

Monograph on economic implications of unemployment benefit for older workers in the USA - comments on legislation restricting unemployment insurance when old age benefits are received, examines impacts on equality of income distribution by age group, consumption, labour force participation and retirement decision making, and argues against restrictions and for a more stringent system of job searching requirements.

Unemployment compensation in the United States is provided through a federal-state system of unemployment insurance (UI). UI provides temporary partial wage replacement to active job seekers who are involuntarily out of work. For older workers, UI is an important source of income security and a potential influence on work incentives. For many, the transition from full-time work in a career job to retirement is voluntary and orderly. For others, job displacement greatly disrupts plans. The transition often involves many intermediate steps. The chain of transitions may include full- or part-time work on another job which most often is not in the same industry and occupation (a bridge job). There may also be movement between bridge jobs, perhaps back from a bridge job to a career job, and finally a gradual movement into full retirement while out of the labor force. Many issues at the forefront of current UI policy debate are also issues of prime importance to those in the second half of their working life. Issues occur in all the standard areas of UI policy: coverage, eligibility, benefit adequacy, duration of benefits, work incentives, benefit financing, and interaction with other programs. This paper provides a brief background sketch of the labor market situation of older workers to examine issues of prime concern to older workers in these areas of UI policy. Our survey of policy issues suggests that changes in UI rules concerning, initial eligibility, continuing eligibility, wage replacement, and partial benefits should all be examined to evaluate effects on the likely employment patterns of older workers. Particular attention should be given to UI features affecting the choice of self-employment, part-time work, seasonal work, and agricultural jobs. The financing consequences of possible UI program changes should also be estimated, as should the macroeconomic impact of broadening recipiency. UI program features which would promote flexible and extended labor force participation by older workers should also enrich the employment choice environment for other workers. Therefore, it would be useful to examine the impact of such program changes on UI as a built-in stabilizer of aggregate expenditures. While younger workers are usually committed to long-term participation in the labor force, older citizens are often more flexible in choosing to use their time. Worsening labor shortage conditions in the United States mean that efforts to retain older workers in the labor force will intensify. The current and potential influence of UI on the income security and labor force participation of older workers should be well understood.

Designing a good unemployment insurance scheme is a delicate matter. In a system with no or little insurance, households may be subject to a high income risk, whereas excessively generous unemployment insurance systems are known to lead to high unemployment rates and are costly both from a fiscal perspective and for society as a whole. Andreas Pollak investigates what an optimal unemployment insurance system would look like, i.e. a system that constitutes the best possible compromise between income security and incentives to work. Using theoretical economic models and complex numerical simulations, he studies the effects of benefit levels and payment durations on unemployment and welfare. As the models allow for considerable heterogeneity of households, including a history-dependent labor productivity, it is possible to analyze how certain policies affect individuals in a specific age, wealth or skill group. The most important aspect of an unemployment insurance system turns out to be the benefits paid to the long-term unemployed. If this parameter is chosen too high, a large number of households may get caught in a long spell of unemployment with little chance of finding work again. Based on the predictions in these models, the so-called "Hartz IV" labor market reform recently adopted in Germany should have highly favorable effects on the unemployment rates and welfare in the long run.
