This paper explores implications of nominal rigidity characterized by a non-constant hazard function for aggregate dynamics. I derive the NKPC under an arbitrary hazard function and parameterize it with the Weibull duration model. The resulting Phillips curve involves lagged inflation and lagged...

This paper demonstrates that tractability gained from the Calvo pricing assumption is costly in terms of aggregate dynamics. I derive a generalized New Keynesian Phillips curve featuring a generalized hazard function, non-zero steady state inflation and real rigidity. Analytically, I find that...

This paper explores what can be lost when assuming price adjustment is a time - independent (memoryless) process.I derive a generalized NKPC in an optinizing model with the non- constant hazard function and trend inflation. Memory emerges in the resulting Phillips curve through the presence of...

This paper presents a new formulation of conflict inflation labeled the "pass-through" approach, which contrasts with the existing "pressure balance" approach. The model generates Phillips styled inflation - unemployment dynamics that are a hybrid of Keynesian and NAIRU dynamics. Conflict...

Real rigidities are an important feature of modern sticky price models and are policyrelevant because of their welfare consequences, but cannot be structurally identified from time series. I evaluate the plausibility of capital specificity as a source of real rigidities using a two-dimensional...

This paper provides an alternative explanation for the recent empirical evidence (Stock and Watson, 2007 and Cogley et al., 2010) showing that a random walk dynamic component accounts for much of the persistence in inflation. I use a time-dependent sticky price model and study the mapping from...

We show that after monetary policy announcements, the conditional volatility of stock market returns rises more for firms with stickier prices than for firms with more flexible prices. This differential reaction is economically large and strikingly robust to a broad array of checks. These...

We show that a negative relative demand shock in a sector with downwardly rigid prices, like the service sector, can generate substantial inflation. Such a shock induces an equilibrium decline in the relative price of services. If price adjustment costs are non-existent or symmetric, then this...
