The Economics of Star Trek
Leonard suggests that the reference in the movie is a shout-out to Paul Romer's work. Maybe so, but that is less obvious to me. Paul certainly used the terms "excludable" and "rival" in his famous work on economic growth, and to great effect, but these terms predate Paul's work. Indeed, they are the standard terms that public finance economists have long used to distinguish private and public goods. Today at Harvard, most students first learn these words when studying the basics of public finance rather than the theory of long-run growth. I won't venture a guess about the Vulcan curriculum.
By the way, the Star Trek movie is a lot of fun.
