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...

This paper discusses the likely evolution of U.S. inflation in the near and medium term on the basis of (1) past U.S. experience with very low levels of inflation, (2) the most recent Japanese experience with deflation, and (3) recent U.S. micro evidence on downward nominal wage rigidity. Our...

I investigate the welfare maximizing steady-state inflation rate in a heterogeneous-agent New Keynesian model with Downward Nominal Wage Rigidity (DNWR). After matching the annual wage change distribution in the U.S., I show that DNWR has a very significant impact on the economy when the...

We document empirical regularities of disaggregated inflation and consumption and study whether multisectoral New Keynesian models can explain them. We focus on higher moments of the inflation and consumption growth distributions as well as on the contemporaneous comovement of these two...

Existing menu cost models, when parameterized to match the micro-price data, cannot reproduce the extent to which the fraction of price changes increases with inflation. In addition, in the presence of strategic complementarities, they predict implausibly large menu costs and misallocation. We...

The price system, the adjustment of prices to changes in market conditions, is the primary mechanism by which markets function and by which the three most basic questions get answered: what to produce, how much to produce and for whom to produce. To the behaviour of price and price system,...

Inflationary processes are closely linked to wage-price spirals - such spirals can be triggered by many factors, including natural resource price shocks, depreciation and inflationary demand. Empirically, the correlation between changes in nominal unit labour costs and the price level is strong...

This paper examines the asset pricing implications of nominal rigidities. Firms that adjust their product prices infrequently earn a return premium of 4% per year. Merging unique product-price data at the firm level with stock returns, I document that the premium for sticky-price firms is a...
