  9. Case Study Using A Regression Model: A Huge Sports Contract • Alex Rodriguez hired by the Texas Rangers for something like $25 million per year in 2000. • Costs – the salary plus and minus some fine tuning of the numbers • Benefits – more fans in the stands. • How to determine if the benefits exceed the costs? Use a regression model.

  10. Baseball Data (Panel Data – 31 Teams, 17 Years)

  13. Marginal Value of an A Rod • 8 games * 32,757 fans + 1 All Star = 35957 = 298,016 new fans • 298,016 new fans * • $18 per ticket • $2.50 parking etc. • $1.80 stuff (hats, bobble head dolls,…) • $6.67 Million per year !!!!! • It’s not close. (Marginal cost is at least $16.5M / year)

  14. Course Prerequisites • Basic algebra. (Especially summation) • Geometry (straight lines) • Logs and exponents • NOTE: I (you) will use only base e (natural) logs, not base 10 (common) logs in this course. • Previous course in basic statistics – up to testing a hypothesis about a mean
