Using a micro-level model to generate a macro-level model of productive successful aging

Area of Science:

• Gerontology
• Sociology
• Public Health

Background:

• Successful aging involves physical, cognitive, and social-productive engagement.
• Productive activity is a key factor in successful aging.
• Existing micro-level models explain individual productivity; macro-level models are needed.

Purpose of the Study:

• Develop and test a macro-level model of productive activity.
• Examine predictors of productivity and its relationship with well-being.
• Analyze labor force participation rates and average life expectancy across OECD countries.

Main Methods:

• Used random effects regression and path analysis.
• Analyzed longitudinal data from 24 high-income OECD countries (1980-2010).
• Included 168 observations, examining male and female data.

Main Results:

• Higher older worker labor force participation correlates with higher life expectancy.
• Labor force participation mediates the impact of GDP per capita on life expectancy.
• It also mediates self-employment effects for men and suppresses public spending effects.

Conclusions:

• A micro-level model of productive activity can be adapted for macro-level analysis.
• This macro-level model effectively explains cross-national variations in productivity and well-being.
• Findings underscore the link between economic participation and longevity.
