Social security, provision of public sector services, job security legislation, minimum wages and centrally regulated (bargained) relative wages are important elements of the modern welfare state -- each designed, often quite successfully, to enhance economic security and to redistribute income. The consequences of these policies for the unemployment issue are the topic of this paper.

We characterize pension systems along three dimensions: 1) actuarial vs. non-actuarial, 2) funded vs. pay-as-you-go, 3) defined-contribution vs. defined-benefit. Increasing the degree of actuarial fairness, by strengthening the linkage between contributions and benefits, reduces labor market distortions and may increase welfare in a Pareto-efficiency sense. Increasing the degree of funding implies mainly a redistribution of income among generations, although a partial shift to funding also provides better risk-return combinations for individuals. Shifting from defined-benefit to defined-contribution schemes (with fixed contribution rates) shifts the income risk from workers and taxpayers to pensioners.
