Outline of Final Research Achievements

In this research project, we modify the individual agent-simulation-model to a household agent-simulation-model. Based on the model, we estimate the replacement rate for various types of households in order to consider measures the government or the household should take. We introduce a marital model in our model to produce six types of households such as (1, 1), (1, 2), (2, 1), (2, 2), (2, 3), and (3,2) where 1 is the first-grade insured person, 2 is the second-grade insured person, and 3 is the third-grade insured person. We calculate the replacement rate for those couples, and find that the average replacement rate the couple of (1, 1) will be 36.7% toward the average wage that a current worker earns. That shows some support should be needed for those couples.
