Empirical estimations of the New Keynesian Phillips curve support hybrid versions with a positive weight on lagged infl ation and a weight less than one on expected infl ation. We argue that myopic price setting of some agents explains the low weight on expected infl ation. The lagged term can...

We experimentally test the price-setting behavior of firms in the Rotemberg (1982) model in order to explain puzzles in the New Keynesian Phillips curve (NKPC). By constructing categories and a quantitative measure that compare behavior with optimum we find heterogeneous price-setting behavior...
