We study the implications of increased price flexibility on output volatility. In a simple DSGE model, we show analytically that more flexible prices always amplify output volatility for supply shocks and also amplify output volatility for demand shocks if monetary policy does not respond...

Using micro-data on U.S. producer prices, we establish three new facts about price setting by multi-product firms. First, firms selling more goods adjust prices more frequently but on average by smaller amounts. Moreover, their fraction of positive price changes is lower and the dispersion of...

We prove that the Generalized Taylor Principle, under which the nominal interest rate reacts more than one-for-one to a change in inflation in the long run, is a necessary and (under some extra mild restrictions on parameters) sufficient condition for determinacy in a sticky price model with...

Using a micro-founded model and a likelihood-based inference method, we show that while a passive monetary and passive fiscal policy regime prevailed in the U.S. before Paul Volcker's chairmanship at the Federal Reserve, an active monetary and passive fiscal policy regime prevailed after his...

We explain why international nominal bonds and equity portfolios are biased domestically. In our model, holding domestic government nominal debt provides a hedge against shocks to bond returns and the impact on taxes they induce. For this result, only two features are essential: nominal risk and...
