Trading Off Business and Family Investments: Evidence from U.S. Entrepreneurial Households

Investing in children’s human capital reduces business investments for U.S. entrepreneurial households. Using financial account data of 90,000 small businesses linked to their owners and a regression discontinuity design that compares the business performance of households with college-aged dependents (18–22) to those with near-college-aged dependents (14–17), I show that business revenues and expenses decline sharply when owners’ children reach age 18. Despite the declines, profitability and productivity remain largely unaffected, suggesting a general downsizing rather than a loss in efficiency. Heterogeneity analysis shows that downsizing is concentrated among highly indebted owner households and businesses with volatile cash flows. For each dollar increase in household spending associated with a child turning 18, business expenses decline by $2.26. These findings are consistent with entrepreneurial parents reallocating capital from business investments toward their children’s human capital, as both compete for the same pool of internal family financial resources.
