DYNASIM2 AND PRISM: EXAMPLES OF DYNAMIC MODELING 136 and incomes far into the future. Changes in demographic events and labor supply are quite likely once a significant policy change has occurred. For example, policy changes that make the social security system less generous are likely to lead to compensating changes in labor supply, savings behavior, and retirement plans by people who are 30 years away from the “normal” retirement age. Currently, the dynamic models could incorporate a response if an analyst changed parameters for labor force participation, but this response would not be based on an explicit relationship between the policy change and labor supply decisions. New development work on the DYNASIM2 model will improve its flexibility by fully integrating the retirement decision with other demographic and economic events and with policy changes. Further development to expand opportunities for policy changes to feed back to demographic and economic events would enable both of these models to reflect current theory and estimates of behavioral responses to policy. Finally, the models would be better served by documentation that is clear, well-organized, and up-to-date. These are very large and complex computer models, and the documentation for both PRISM and DYNASIM2 contains sections that are too tersely written to provide a full understanding of essential features of the models and how those features interact. Leaving so muc h to the imagination does not help to convince an analyst that the model is a sound policy analysis tool. In addition, at least one of the module descriptions included in the current documentation of DYNASIM2 is from a prior version of that module. Accessible, current documentation should be integrated with model development efforts. This would, at least, help market the models to potential users and funders, and, at best, help analysts to more fully exercise the capabilities of these models for policy analysis.

This volume, second in the series, provides essential background material for policy analysts, researchers, statisticians, and others interested in the application of microsimulation techniques to develop estimates of the costs and population impacts of proposed changes in government policies ranging from welfare to retirement income to health care to taxes.

The material spans data inputs to models, design and computer implementation of models, validation of model outputs, and model documentation.
