The purpose of this study is to examine longitudinally the effect of life satisfaction on the slope of income and the effect of income on the slope of life satisfaction. It also reveals how life satisfaction and income trajectory has been influenced by the factors of health condition and productive activities. The subjects for the study were drawn from the aged older than 55 years old from Korean Retirement and Income Study Data. We find that the life satisfaction and income is positively correlated, however, life satisfaction has negative impact on the slope of income while income also has negative impact on the slope of life satisfaction. The health condition did explain life satisfaction and income trajectory, and the productive activities also show some significant importance. These findings suggest that life satisfaction and income play important roles each other and it is necessary to develop programs for improving the physical and psychological health and to provide appropriate jobs and wage for the elderly.
