This paper analyzes the implications of heterogeneity in price setting for both price and inflation inertia. Standard models based on Taylor- or Calvo-style price setting usually assume ex-ante identical firms, while Calvo's approach implies only ex-post heterogeneity. While it is known that...

This paper analyzes the implications of heterogeneity in price setting for the real effects of monetary shocks. Starting from otherwise standard sticky price and sticky information models, I introduce ex-ante heterogeneity in terms of price setting frictions, and compare the resulting dynamics...

The real effects of an imperfectly credible disinflation depend critically on the extent of price rigidity. Therefore, the study of how the policymaker's credibility affects the outcome of an announced disinflation should not be dissociated from the analysis of the determinants of the frequency...

When policy rules are changed, the effect of nominal rigidities should be modelled through endogenous pricing rules. We endogenize Taylor (1979) type pricing rule to examine the output effects of monetary disinflations. We derive optimal fixed-price time-dependent rules in inflationary steady...

Myopic loss aversion has been used to explain why a high equity premium might be consistent with plausible levels of risk aversion. The intuition is that it plays the role of high risk aversion in portfolio choice. But if so, should these agents not perceive larger gains from international...
