JD/MBA’s in law departments more than in law firms?

Wouldn’t it make sense a priori that many who obtain the two degrees – an LLB or JD and an MBA – would gravitate toward the overlap of business and law – a law department? Someone could pore through directories and gather some data on the incidence of in-house lawyers who have the combined degrees.

Or do such students value and excel at academics, which draws them toward teaching? Then again, being hardworking and disciplined, do JD/MBAs end up as partners in a law firm?

Or do none of these outcomes dominate, as joint degree holders chuck the law and move into business? The resident advisor on my floor sophomore year, Jim Koch, got a JD and an MBA from Harvard, and now is the CEO of Sam Adams Brewing.
