The recent literature on monetary policy in the presence of a zero lower bound on interest rates has shown that forward guidance regarding the path of interest rates can be very effective in preserving macroeconomic stability in the face of a contractionary demand shock; moreover, that...

connections to ongoing research in marketing and consumer behavior.

Although the Dixit-Stiglitz aggregator is the workhorse specification of monopolistic competition, this framework and related variants abstract from a key stylized fact from empirical studies of consumer behavior and product marketing, namely, that the price elasticity of demand for a given...

In this paper, we show that strategic complementarities--such as firm-specific factors or quasi-kinked demand--have crucial implications for the design of monetary policy and for the welfare costs of output and inflation variability. Recent research has mainly used log-linear approximations to...

Macroeconometric equivalence means that estimates of DSGE models using first-order approximations to equilibrium conditions fail to distinguish between alternative preference/technology configurations. Microeconomic dissonance means that the underlying microeconomic differences between...
