가계소비의 회복력과 소득탄력성의 변동패턴 분석

As the income gap between worker households and non-worker households in Korea gradually widens, the purpose of this study is to identify differences in consumption patterns between worker households and non-worker households. By estimating the error correction equation, it was found that both worker households and non-worker households have small error correction coefficients for communication, health, and food expenses, and in particular, the adjustment speed of communication and health expenses is small, so they experience considerable difficulty in adjusting communication and health expenses. The error correction coefficients of worker households are larger than those of non-worker households in food, clothing, shoes, housing, transportation, and education, so expenditure adjustments are made quickly. However, the error correction coefficients of worker households are smaller than those of non-worker households in communications, entertainment, food, lodging, and non-consumption expenditures, so expenditure reductions are more likely to occur for non-worker households. It is revealed that adjustments are made more slowly compared to maternal households. In particular, the speed of adjustment in non-consumption expenditures for non-working households is much greater, showing that working households are taking a much more cautious approach to reducing spending for retirement. Moving regression analysis shows that the increase in expenditures for items excluding health and food expenses tends to gradually decrease, and while the non-consumption expenditures of working households gradually increase, the non-worker households gradually become smaller, leading to worker households becoming self-employed due to retirement anxiety. It is revealed that they are preparing more than before.
