Albert Saiz, an economist at the University of Pennsylvania, and Elena Zoido, an economist at the consulting group LECG, published a study comparing wage premiums for American college graduates who spoke Spanish, French, German, Italian, Russian and Chinese as a second language.In their findings, the law of supply and demand prevailed. With its 1.7% wage premium, Spanish was the least valuable, followed by French (2.7%). Knowledge of German, Italian, Russian and Chinese was slightly more valuable, translating into an average 4% income boost.
For a recent MBA, or a new graduate in engineering, this could mean $2300 or more in your pocket each year. For an experienced worker several years out of college, it would be double that or more.
