Guess Who Loses?

Game theory tells us that a risk neutral gambler would pay $50 dollars for a coin flip that paid $0 for Heads and $100 for Tails. Game theorists would call $50 the value of the bet.

Suppose someone is willing to fund your gambling problem, and lend you $80 at zero interest. Better still, if you lose the bet you don’t have to pay him back. Under that scenario, the same gambler would pay $90 for the bet, giving him an even chance of winning or losing $10.




This is a microcosm of what the Public-Private Investment Program (PPIP) is intended to do: create an incentive for investors to pay $90 for a bet that is only worth $50. It is bad economics and bad public policy and it is probably fraudulent. Congress should act pre-emptively to halt Treasury Secretary Tim Geithner’s latest scheme.

Paul Krugman pointed out that the plan is a “disguised way to subsidize purchases of bad assets.” Josef Stiglitz commented that Geithner’s plan “only works if the taxpayer loses big time.”
