The market value of government debt equals the present discounted value of primary surpluses. Applying present value decompositions from asset pricing to this valuation equation, I find that half of the variation in the market value of debt to GDP ratio corresponds to varying forecasts of future...

Conventional models of production under uncertainty specify that output is produced in fixed proportions across states of nature. I investigate a representation of technology that allows firms to transform output from one state to another. I allow the firm to choose the distribution of its...

How should long-term investors form portfolios in our time-varying, multifactor and friction-filled world? Two conceptual frameworks may help: looking directly at the stream of payments that a portfolio and payout policy can produce, and including a general equilibrium view of the markets'...

I use the valuation equation of government debt to understand fiscal and monetary policy in and following the great recession of 2008-2009, to think about fiscal pressures on US inflation, and what sequence of events might surround such an inflation. I emphasize that a fiscal inflation can come...

Bennett McCallum (2009), applying Evans and Honkapohja's (2001) results, argues that "learnability" can save New-Keynesian models from their indeterminacies. He claims the unique bounded equilibrium is learnable, and the explosive equilibria are not. However, he assumes that agents can directly...

If one accepts the new-Keynesian solution, the parameters of the Taylor rule relating interest rates to inflation and other variables are not identified without unrealistic assumptions. Thus, Taylor rule regressions cannot be used to argue that the Fed conquered inflation by moving from a...

To question the statistical significance of return predictability, we cannot specify a null that simply turns off that predictability, leaving dividend growth predictability at its essentially zero sample value. If neither returns nor dividend growth are predictable, then the dividend-price...
