In practical applications of micro-simulation models (MSMs), very little is usually known about the properties of the simulated values. This paper argues that we need to apply the same rigorous standards for inference in micro-simulation work as in scientific work generally. If not, then MSMs...

This paper focuses on three issues. First, it analyzes the increasing inequality of wealth in Sweden in terms of percentile age and birth cohort differences, and finds very weak evidence of life-cycle savings. There are rather strong birth cohort differences in wealth accumulation. Second, it is...

For the purpose of studying the consequences of the ageing of the Swedish population a group of scientists have enlarged the microsimulation model SESIM - originally developed at the Swedish Ministry of Finance - with modules that simulate health status, take up of sickness benefits, retirement,...

Influenced by major tax reform in the early 1990s and by the exceptional boom in the stock market at the end of that decade, overall wealth in Swedish households increased. So did wealth inequality. The large baby- boom cohorts of the 1940s have been successful in accumulating wealth and they...

Many Western countries with an aging population consider reforms of their pay-as-you-go pension systems. In Sweden a new pension system has already been decided and implemented. This paper gives a brief background to the Swedish reforms in the 1990s and explains the structure of the new system.

Reviewing trends in the Swedish distribution of wealth it is demonstrated that the baby-boom cohorts have become relatively wealthy, both in terms of private wealth and in claims on the pension system. Results from a simulation model suggest that the elderly in the future will no longer belong...
