Business, Economics, or Finance versions of RSI/TASP?

I see good recommendations for LEAD or LBW at Wharton; however, I would like to know the competitiveness of the programs.

Is there business/finance/economics summer program AS (or close to being) competitive as TASP or RSI?

As of now it only looks like the two I mentioned are the best, but I still believe there is at least one extremely selective business/finance/economic summer program out there.
