This paper examines the pricing of public debt in a quantitative macroeconomic model with government default risk. Default may occur due to a fiscal policy that does not preclude a Ponzi game. When a build-up of public debt makes this outcome inevitable, households stop lending such that the...

We investigate expectation formation in a controlled experimental en-vironment. Subjects are asked to predict the price in a standard asset pricingmodel. They do not have knowledge of the underlying market equilibrium equa-tions, but they know all past realized prices and their own predictions....

Empirical measures of world consumption growth risk have failed to rationalize the cross-section of country equity returns. We propose a new factor, termed “the global consumption factor”, to explain the patterns in risk premiums on international equity markets. We identify this factor as...

We test whether asymmetric preferences for losses versus gains as in Ang, Chen, and Xing (2006) also affect the pricing of cash flow versus discount rate news as in Campbell and Vuolteenaho (2004). We construct a new four-fold beta decomposition, distinguishing cash flow and discount rate betas...
