I investigate a Danish policy reform that postpones social security eligibility tied to an increase in life expectancy. The reform creates sharp discontinuities based on exact birth dates, allowing for the identification of causal effects. Using both administrative and survey data, I document a...

We study retirement incentives with augmented option value model à la Stock and Wise (1990). We propose methodological extensions to better reflect the respective incentives faced by singles and couples. Our results show that a more comprehensive modelling of couples' incentives leads to very...

We study the relationship between early claiming of pensions and incentives in the highly flexible Norwegian public pension system, measuring incentives to claim based on an estimated model for expected longevity. Despite a strong correlation between incentives and claiming decisions, the...

Many Americans claim Social Security benefits early, though this leaves them with lower benefits throughout retirement. We build a lifecycle model that closely tracks claiming patterns under current rules, and we use it to predict claiming delays if, by delaying benefits, people received a lump...

The gains in life expectancy are expected to double the dependency ratio and increase population by 10% in Switzerland until 2050. To quantify the effects on social security and public finances, we use an overlapping generations model with five margins of labor supply: labor market...

A much higher old-age dependency ratio together with more generous pension benefits will lead to a substantial increase in the future pension burden in Norway. The challenges of financing the increasing pension expenditures depend on the development in demographic characteristics like fertility,...

A much higher old-age dependency ratio, together with more generous pension benefits, will lead to a substantial increase in the future public pension expenditures burden in Norway. A pension reform implemented from 2010 will imply a shift to a quasi-actuarial system, seeking to neutralise the...

As a preliminary step, we first provide some new empirical evidence that labor market conditions affect retirement decisions at the individual level: unemployed people are more likely to retire. Our main objective in this paper is then to propose an equilibrium unemployment approach to...

While the effect of social security systems on retirement decisions has received much attention, the impact of these systems on individuals incentives to invest in their human capital has not been analyzed. We integrate human capital investment and retirement decisions in a simple analytical...
