My expertise was in public finance, particularly corporate taxation, since I had worked at the US Treasury.

My main interest, however, was in economics, not law.

Of course. I favor passive investing for most investors, because markets are amazingly successful devices for incorporating information into stock prices.

My research interests since then have shifted strongly towards the economic and regulatory problems of the financial services industry, and especially of the securities and options exchanges.

One of my biggest problems with comedy was that I did not understand some of the jokes.

My father tried to discourage me from going into comedy, mainly because he felt like it wasn't promising. It was pie in the sky.

I hadn't done just a straight-out comedy in a long time, just letting an ensemble do really good character acting, having them carry the movie as in my earlier pictures.

The main thing about doing a comedy is that you spend most of your days really happy and laughing.
