We study the pricing of political uncertainty in a general equilibrium model of government policy choice. We find that political uncertainty commands a risk premium whose magnitude is larger in poorer economic conditions. Political uncertainty reduces the value of the implicit put protection...

We develop a simple approach to valuing stocks in the presence of learning about average profitability. The market-to-book ratio (M/B) increases with uncertainty about average profitability, especially for firms that pay no dividends. M/B is predicted to decline over a firm's lifetime due to...

We calculate the costs and benefits of the largest ever U.S. Government intervention in the financial sector announced the 2008 Columbus-day weekend. We estimate that this intervention increased the value of banks’ financial claims by $131 billion at a taxpayers’cost of $25 -$47 billions...

We analyze how changes in government policy affect stock prices. Our general equilibrium model features uncertainty about government policy and a government that has both economic and non-economic motives. The government tends to change its policy after performance downturns in the private...

Not necessarily. The fundamental value of a firm increases with uncertainty about average future profitability, and this uncertainty was unusually high in the late 1990s. We calibrate a stock valuation model that includes this uncertainty, and show that the uncertainty needed to match the...

We survey the recent literature on learning in financial markets. Our main theme is that many financial market phenomena that appear puzzling at first sight are easier to understand once we recognize that parameters in financial models are uncertain and subject to learning. We discuss phenomena...

The housing crisis threatens to destroy hundreds of billions of dollars of value by causing homeowners with negative equity to walk away from their houses. A house in foreclosure is worth 30 to 50 percent less than a house that a homeowner either retains or sells on the market, and a foreclosed...
