Abstract: This is the introduction and summary to the fifth phase of an ongoing project on Social Security Programs and Retirement Around the World. The first phase described the retirement incentives inherent in plan provisions and documented the strong relationship across countries between social security incentives to retire and the proportion of older persons out of the labor force. The second phase documented the large effects that changing plan provisions would have on the labor force participation of older workers. The third phase demonstrated the consequent fiscal implications that extending labor force participation would have on net program costs-reducing government social security benefit payments and increasing government tax revenues. The fourth phase presented analyses of the relationship between the labor force participation of older persons and the labor force participation of younger persons in twelve countries. We found no evidence that increasing the employment of older persons will reduce the employment opportunities of youth and no evidence that increasing the employment of older persons will increase the unemployment of youth.
This phase is intended to set the stage for and inform future more formal analysis of disability insurance programs, with this key question: Given health status, to what extent are the differences in LFP across countries determined by the provisions of disability insurance programs? Here we first consider changes in mortality over time and in particular the relationship between mortality and labor force participation, thinking of mortality as one indicator of health that is comparable across countries and over time in the same country. We then consider how mortality is related to other indicators of health status, in particular self-assessed health and then how trends in DI participation are related to changes in health. Finally we consider the effect on disability insurance participation of "natural experiments" in which the disability insurance reforms were not prompted by changes in health status or by changes in the employment circumstances of older workers. We find that these "exogenous" reforms can have a very large effect on the labor force participation of older workers.NBER Working Paper No. 16719, January, 2011: Abstract/Paper.
Abstract: In this paper, we begin an examination of the impact of disability insurance on elderly Canadians. To do so, we pursue an analysis of the long-run trends in Canada Pension Plan disability insurance participation. We relate these trends to observed changes in different measures of health and an institutional analysis of policy changes, in order to understand what is driving the changes in disability insurance receipt through time.Pre-publication draft, April, 2011: PDF.
Abstract: In this paper, I pursue two goals. First, I provide long time-series of data from a variety of sources related to Social Security Disability Insurance. These long time series, with data stretching almost 60 years from 1950 to 2009, allow for perspective and context on the different potential causes of the growth of the program. The second goal is to provide data that are comparable to what is available in other countries in this project. This comparability will help place the experience in the United States in context, and the cross-country comparisons may also yield important insights.Pre-publication draft, April, 2011: PDF.
