For a given frequency of price changes, the real effects of a monetary shock are smaller if adjusting firms are disproportionately likely to have last set their prices before the shock. This type of selection for the age of prices provides a complete characterization of the nature of pricing...

Price selection is a simple, model-free measure of selection in price setting and its contribu- tion to in ation dynamics. It exploits comovement between in ation and the level from which adjusting prices departed. Prices that increase from lower-than-usual levels tend to push in a- tion above...

Ordinary Least Squares (OLS) estimation of monetary policy rules produces potentially inconsistent estimates of policy parameters. The reason is that central banks react to variables, such as in ation and the output gap, which are endogenous to monetary policy shocks. Endogeneity implies a...

We study a unique dataset with comprehensive coverage of daily prices in large multi-product retailers in Israel. Retail stores synchronize price changes around occasional "peak" days when they reprice around 10% of their products. To assess aggregate implications of partial price...

We propose a model that reconciles microeconomic evidence of frequent and large price changes with sizable monetary non-neutrality. Firms incur separate lump-sum costs to change prices and to gather and process some information about marginal costs. Additional relevant information is...

We develop a theory of low-frequency movements in in ation expectations, and use it to interpret joint dynamics of in ation and in ation expectations for the United States and other countries over the post-war period. In our theory long-run in ation expectations are endogenous. They are driven...

Estimamos um modelo dinâmico, estocástico, de equilíbrio geral para a economia brasileira, levando em conta explicitamente a transição do sistema de bandas cambiais para o regime de metas para a inflação com câmbio flutuante, ocorrida em 1999. O modelo estimado produz dinâmicas bastante...

We estimate a dynamic, stochastic, general equilibrium model of the Brazilian economy taking into account the transition from a currency peg to inflation targeting that took place in 1999. The estimated model exhibits quite different dynamics under the two monetary regimes. We use it to produce...

The demographic transition can affect the equilibrium real interest rate through three channels. An increase in longevity - or expectations thereof - puts downward pressure on the real interest rate, as agents build up their savings in anticipation of a longer retirement period. A reduction in...
