We study optimal monetary policy design in a simple model that deviates from the linear-quadratic paradigm and provides a rationale for the practice of inflation zone targeting. We show that the presence of either zone-quadratic preferences or a zonelinear relationship between inflation and economic activity provides strong incentives to deviate from conventional linear policies. We calibrate t...

We formulate a consumption-based asset pricing model in which aggregate risk aversion is time-varying in response to both news about consumption growth (as in a habit formation model) and news about inflation. We estimate our model and explore its pricing implications for the term structure of interest rates and the cross-section of stock returns. Our empirical results support the hypothesis th...

This paper provides an empirical investigation into the relationship between ex ante U.S. labor contract durations and uncertainty over the period 1970 to 1995. We construct measures of inflation uncertainty as well as aggregate nominal and real uncertainty. The results not only corroborate previous findings of an inverse relationship between contract duration and inflation uncertainty, but als...

I nvestors and market analysts generally believe that the yield on a nominal bond includes an inflation risk premium to compensate investors for bearing the inflation risk associated with the bond. Knowing how much of a risk premium investors require on nominal bonds can be valuable information for policymakers. For government Treasuries, the size of the risk premium represents the potential in...

String/M theory inspires an uncertainty relation between space and time which deviates from general relativity. It is possible to explore this deviation from cosmological observations, in particular from the CMB fluctuation spectrum. This paper extends some previous observations to more general inflation schemes, we find that the noncommutative spacetime effects always suppress the power spectr...
