Dad’s Brains More Important to Son’s Success Than Money

Dads Brains More Important to Sons Success Than Money New research shows that sons of fathers with high incomes tend to end up with higher incomes themselves, but it’s not just dad’s money that helps the son succeed.

Rather, it’s what researchers call the “human capital endowments” passed from father to son, such as “smarts,” advice, work ethic, and other intangibles that are more important to a son’s success than the size of their dad’s bank account.

“We know there’s a correlation between fathers’ income and sons’,” said David Sims, an economics professor at Brigham Young University and one of the study’s authors.

“What’s gotten less attention is the mechanism. We wanted to see if the intergenerational income correlation is due to money — what we can buy for our kids— or if human capital attributes passed from father to son play a role as well.”

The problem is that separating the two inputs is tricky, he said. On average, fathers with higher human capital endowments also tend to have higher incomes, so it’s hard to tell which factor is doing what.

The researchers began with the following thought experiment:

Take two smart, similarly skilled and educated fathers. Say one lived in a town with a robust labor market and had a big salary.

The other father wasn’t so lucky. He lived in a town with a depressed labor market, and had much lower earnings despite his comparable human capital.

If money is the only thing that matters in the transfer of income between generations, then we’d expect that the son of the lucky father would end up with a higher income than the son of the unlucky father. However, if human capital matters, the two sons may end up with more similar incomes.

To test this idea, the researchers used detailed government administrative data on a large sample of Swedish fathers with sons born between 1950 and 1965. The data included salary information for fathers and sons as well as clues about fathers’ human capital: education levels and the nature of their occupations.

Fathers with more education or those who work in jobs that require specialized skills are considered to have higher human capital endowments that could be passed to sons, the researchers postulated.

Sims and his colleagues looked for a raw correlation between fathers’ incomes and their sons’, which, as expected, was quite strong. Then they employed a statistical methodology to isolate differences in fathers’ income due to something other than human capital, as in the example of similar fathers who worked in differing labor market conditions.

If the income correlation weakens for fathers and sons in these types of situations, the researchers could conclude that money isn’t the only thing that matters.

And that’s exactly what the study found. Income differences not related to a father’s human capital were weaker predictors of a son’s income. In other words, human capital matters, the researchers said.

In fact, human capital endowments passed from father to son accounted for about two-thirds of the overall intergenerational income relationship, according to Sims said.

“We don’t offer a final answer here, but we do offer some boundary conditions and present a methodology that could help unravel the question,” he concluded.

The study was recently published in the Journal of Political Economy.
