Abstract: |
After three years in the National Collegiate Athletic Association (NCAA),
collegiate football players face a trade-off between spending more time in the
NCAA and pursuing a career in the National Football League (NFL) by declaring
for the draft. We analyze the starting salaries and signing bonuses for 1,673
rookies in the NFL, who entered the league between 2001 and 2009 through the
NFL draft. We instrument the endogenous decision to enter the professional
market with a player's month of birth. A player's true talent is only
imperfectly observed and the instrument provides a causal link between time at
college and subsequent salaries in the NFL through the relative age effect.
Our estimates suggest that a player enjoys a 6% higher starting salary in the
NFL, and a 15% higher first-year signing bonus, for each year with the college
team. On average, a rookie is estimated to earn $131,000 more in his rookie
season, if he enters the NFL one year later. Our analysis of a typical labor
market in professional sports shows that the returns to education in sports
are sizeable and surprisingly similar to returns to formal education. The
results of our analysis provide information for the players who are deciding
about declaring for the draft, however, also colleges and the teams in the NFL
may find the results of interest. |
