David Forrest is two different authors...

... or three, depending on how you count. David Eliades and Robert Forrest Webb teamed up to write And to My Nephew Albert I Leave the Island What I Won Off Fatty Hagan in a Poker Game and some other humorous topical fiction. I'd be willing to bet the David Forrest who wrote the economics books needs his own author page. Thanks for confirming & separating!
