자가주택소유의 묵시적 소득을 고려한 소득불평등 연구 = Impact of Imputed Income from Owner-Occupied Housing on Income Inequality

다국어 초록 (Multilingual Abstract)

This paper examines the impact of imputed income from owner-occupied housing on household`s income inequality. An ower-occupier earns implicit income from not paying rent for her house whereas she has to pay rent if renting. This imputed income is found to take unignorable portion of the household`s total income. Using KLIPS data in 2005, we measured total income inequality and then decomposed it by income sources including imputed income from owner-occupied housing. We then analyzed the marginal contribution of imputed income to total income inequality. It was found that, based on owner-occupier sample, the Gini coefficient of imputed income was 0.55, higher than that of labor income but much lower than other income sources such as financial income and property income. The relative marginal impact of imputed income on total income inequality was-0.023, meaning that 1% increase in imputed income decreases total income inequality by 0.023%. Imputed income worked as an equalizing factor of total income inequality for owner-occupiers. Based on full sample including non owner-occupiers, the Gini coefficient of imputed income was found to be 0.73, greater than that from owner-occupier sample. The relative marginal impact of imputed income was 0.007, meaning that imputed income has a negligible impact on total income inequality. These results indirectly suggest that government policies to support homeownership can moderately contribute to lessen income inequality.
