교육투자가 가구 창업과 고소득 가구 확률에 미치는 영향

This study examines the impact of household education investments on the likelihood of household start-ups and their success, using data from the Korean Labor and Income Panel Study (KLIPS) conducted by the Korea Labor Institute from 2013 to 2022. The analysis utilized 186,128 observations and employed fixed-effects panel logit models and propensity score matching (PSM) models. The key findings are as follows: (1) Education Levels: The year of education has a significant inverted U-shaped effect on household income, indicating that beyond an optimal level, additional education negatively impacts income. (2) Certifications: Holding more certifications significantly and negatively affects the income of start-up business households. (3) Science and Engineering Majors: Majoring in science and engineering fields significantly positively impacts the income of start-up business households. (4) Short-term vs. Long-term Effects: While majoring in science and engineering fields negatively affects high-income start-ups in the short-term, it boosts their income after three years. (5) Unpaid Family Workers: The number of unpaid family workers significantly positively affects high-income start-ups, with stronger short-term effects than long-term ones. These findings suggest that policies to promote household investment in STEAM (Science, Technology, Engineering, Arts and Mathematics) education and expand educational opportunities may enhance the job opportunities through start-ups at the household level and their success probability and that governmental support for educational programs aimed at enhancing technical and managerial skills can have such positive effects on household income through start-ups in the long run.
