A study on the Factors Influencing Disposable Income of Self-employed Households : Focusing on Comparison with Workers' Households before and after COVID-19

This study used data from the Household financial welfare survey to conduct a regression analysis on the factors affecting disposable income of self-employed households and compared them with the analysis results of workers' households before, and after COVID-19. As a result of the analysis, gender, number of household members, less than 132.2㎡, residential housing prices, and financial assets had a positive effect on disposable income in common before and after COVID-19, regardless of the distinction between self-employed and worker households, and on the contrary, ‘jeonse’ all had a negative effect. The age of the head of the household had the opposite negative effect in self-employed and worker households, respectively. All but self-employed households showed a positive effect on 132.2㎡ in 2019. Apartments showed a positive effect in 2022 except for self-employed households. Monthly rent was negatively affected only in 2019 for both self-employed and worker households. Mortgage loans were positive in 2019 for self-employed households and negative in 2022 for worker households. Housing expenditure showed a positive effect only on self-employed households in 2019. This study is significant in that it analyzed the effect on disposable income, which is the real income of self-employed people, in multiple dimensions through comparison with worker households before and after COVID-19.
