Uncertainty, exchange rate regimes, and national price levels
Large differences in national price levels exist across countries. In this paper, I develop a general equilibrium model predicting that these differences should be related to countries? exchange rate regimes. My empirical findings confirm that countries with fixed exchange rate regimes have higher national price levels than countries with flexible regimes. At the disaggregate level, the relationship between exchange rate regimes and national price levels is stronger for nontraded goods than for traded goods. I also find that measuring the misalignment in national price levels around times of ...

Macroeconomic Drivers and the Pricing of Uncertainty, Inflation, and Bonds
This paper analyzes a new stylized fact: According to financial market prices, the correlation between uncertainty shocks, as measured by changes in the VIX, and changes in break-even inflation rates has declined and turned negative over the past quarter century. It rationalizes this uncertainty-inflation correlation within a standard New Keynesian model with a lower bound on interest rates combined with a decline in the natural rate of interest. With a lower natural rate, the likelihood of the lower bound binding increased and the effects of uncertainty on the economy became more pronounced. ...

Paradoxes and Problems in the Causal Interpretation of Equilibrium Economics
Equilibrium assumptions posit relations between different people's beliefs and behavior without describing a process that causes these relations to hold. I show that because equilibrium models do not describe a causal process whereby one endogenous variable affects another, attempts to decompose the effects of shocks into “direct” and “indirect” effects can suggest misleading predictions about how these models work. Equilibrium assumptions also imply absurd paradoxes: history can determine future behavior without affecting any intervening state variables today; individuals can learn ...
