This morning Treasury Secretary Geithner will hold a briefing to lay out the details of the government's plan to deal with the toxic assets problem of American banks. He provided an overview of the plan in the Wall Street Journal . He writes that the new Public-Private Investment Program is designed to "increase the flow of credit and expand liquidity ." The Public-Private Investment Program will purchase real-estate related loans from banks and securities from the broader markets. Banks will have the ability to sell pools of loans to dedicated funds, and investors will compete to have the ability to participate in those funds and take advantage of the financing provided by the government. The funds established under this program will have three essential design features. First, they will use government resources in the form of capital from the Treasury, and financing from the FDIC and Federal Reserve, to mobilize capital from private investors. Second, the Public-Private Investment Program will ensure that private-sector participants share the risks alongside the taxpayer, and that the taxpayer shares in the profits from these investments. These funds will be open to investors of all types, such as pension funds, so that a broad range of Americans can participate. Third, private-sector purchasers will establish the value of the loans and securities purchased under the program, which will protect the government from overpaying for these assets. Mark Thoma provides a useful way of understanding Geithner's plan. In Thoma's explanation, the toxic assets are cars, and he uses the toxic car problem to demonstrate three possible goverment responses: 1) The government purchases the toxic cars; 2) Subsidies and private partnerships (the Geithner plan); and 3) Nationalization.
