Price-setting models with monopolistic competition and costs of changing prices exhibit coordination failure: in response to a monetary policy shock, individual agents lack incentives to change prices even when it would be Pareto-improving if all agents did so. The potential welfare gains are in...

The Producer Price Index (PPI) for the United States suggests that semiconductor prices have barely been falling in recent years, a dramatic contrast to the rapid declines reported from the mid-1980s to the early 2000s. This slowdown in the rate of decline is puzzling in light of evidence that...

Starting from the assumption that firms are more likely to adjust their prices when doing so is more valuable, this paper analyzes monetary policy shocks in a DSGE model with firm-level heterogeneity. The model is calibrated to retail price microdata, and inflation responses are decomposed into...

In an abstract economic model, we study optimal monetary policy from the timeless perspective under a general state-dependent pricing framework. We find that when firms are monopolistic competitors subject to idiosyncratic menu cost shocks, households have isoelastic preferences, and there is no...

We study the implications for optimal monetary policy of introducing habit formation in consumption into a general equilibrium model with sticky prices. Habit formation affects the model's endogenous dynamics through its effects on both aggregate demand and households' supply of output. We show...

We present a new way of empirically evaluating various sticky price models used to assess the degree of monetary non-neutrality. While menu cost models uniformly predict that price change skewness and dispersion fall with inflation, in the Calvo model both rise. However, CPI price data from the...

This paper reexamines wage and price dynamics in response to permanent shocks to productivity. We estimate a micro-founded dynamic general equilibrium (DGE) model of the U.S. economy with sticky wages and sticky prices using impulse responses to technology and monetary policy shocks. We utilize...

We propose an explanation for the rapid post-entry growth of surviving firms found in recent studies. At the core of our theory is the interaction between adjustment costs and learning by entering firms about their efficiency. We show that linear adjustment costs, i.e., proportional costs,...

This paper develops a framework for measuring digital services in the face of ongoing innovations in the delivery of content to consumers. We capture what Brynjolfsson and Saunders (2009) call "free goods" as the capital services generated by connected consumers' stocks of IT digital goods; this...

We study the term structure of default-free interest rates in a sticky-price model with an occasionally binding effective lower bound (ELB) constraint on interest rates and recursive preferences. The ELB constraint induces state-dependency in the dynamics of term premiums by affecting...
