Signals and Human Capital
An interesting portion of The Best We Could Do is on page 286 when Thi’s parents are allowed to take classes as part of a government program to earn certificates for future employment. This would help them replace the degrees they had earned in Vietnam that employers wouldn’t recognize. They would take various classes on computers, programming, math, etc. excelling at all of them and earning the credits. Later in their life, these classes were critical for them to gain jobs as part of the American workforce and help them support their family. The question posed by this section is in what way did taking these classes truly benefit them when looking for a job?
Traditional thinking says this: the answer is obvious, of course taking those classes helped them earn a job by teaching them new skills and improving their knowledge. Education is one of the determinants of the productivity of labor, an economic concept that measures the value of the output of a worker, and increasing education increases productivity. This causes them to become more desirable to employers, raising the wage that employers are willing to rent (hire) them at. Education creates a better worker, which a firm is willing to pay more for. This relationship allowed the education to benefit Thi’s parents by moving them from struggling to find minimum wage jobs to being able to receive more lucrative job offers.
However, a newer school of thought threatens to upset this previously clear relationship established by classical economics. In 1970, George Akerlof published a paper that proposed an alternate explanation for why education increases wages. He outlined a market of asymmetrical information, where the seller knows whether his product is high or low quality, and the buyer hopes to buy a high-quality product. The certificates don’t increase the innate talent that Thi’s parents have, having already earned degrees as teachers in Vietnam. The certificates are instead “signals” to potential employers that they are highly productive workers and are worth hiring. This allows them to have higher wages and an easier time during the job search.
Johnny, I love you. To add on, having strong credentials often creates a "halo effect" that clouds peoples judgement. For example, if Ms. Valentino grades a classes mock AP tests 1 by 1, with each test consisting of 3 essays, then a student who performed well on the first essay will likely have mistakes overlooked or go unmarked on the second or third essay. I wonder, then, how much of a facade our education is, and how much substance there is when that mask is lifted.
