Mechanical ability reduces the likelihood of attending four-year college.

This study investigates the role of mechanical ability as another dimension that, jointly with cognitive and socio-emotional, affects schooling decisions and labor market outcomes.  

In contrast to the other dimensions, mechanical ability reduces the likelihood of attending four-year college. 

 On average, for individuals with high levels of mechanical and low levels of cognitive and socio-emotional ability, not attending four-year college is the alternative associated with the highest hourly wage (ages 25-30).
