Sectoral Price Facts in a Sticky - Price
نویسندگان
چکیده
We develop a multi-sector sticky-price DSGE model that can endogenously deliver differential responses of prices to aggregate and sectoral shocks. Input-output production linkages induce across-sector pricing complementarities that contribute to a slow response of prices to aggregate shocks. In turn, labor-market segmentation at the sectoral level induces within-sector pricing substitutability, which helps the model deliver a fast response of prices to sector-specific shocks. Estimating the Factor Augmented Vector Autoregression specification of Boivin, Giannoni and Mihov (2009) on data generated by a parameterized version of our model, we find results that resemble what they obtain with disaggregated data for the U.S. economy. We then employ Bayesian methods to estimate the model using aggregate and sectoral data, and find that it accounts extremely well for a wide range of sectoral price facts.

Modelling the Heterogeneous Price Setting Behavior of Firms (DSGE Approach)
Despite the empirical evidence of the difference in the degree of price stickiness of goods and services, in the new standard Keynesian models, the same price stickiness is considered for all firms producing intermediate goods. In recent years, a new generation of pricing models has been introduced to simulate the heterogeneous price setting behavior in which, unlike standard pricing models, th...

متن کاملNominal Price Rigidities in a Multisector Model
This paper uses a multisector sticky price model with cash-in-advance constraint to examine the implications of sectoral nominal price rigidities for the cyclical behavior of sectoral and aggregate movements in prices and output. The data suggest that correlations between sectoral output and price changes are substantially lower than would be implied by a flexible price model with sectoral tech...
متن کاملSectoral price data and models of price setting∗
We use a statistical model to estimate impulse responses of sectoral price indices to aggregate shocks and to sector-specific shocks. In the median sector, 100 percent of the long-run response of the sectoral price index to a sector-specific shock occurs in the month of the shock. The Calvo model and the sticky-information model match this finding only under extreme assumptions concerning the p...
متن کاملA Tale of Two Volatilities: Sectoral Uncertainty, Growth, and Asset-Prices
What is the impact of higher technological volatility on asset-prices and macroeconomic aggregates? I find the answer hinges on its sectoral origin. I document several novel empirical facts: Volatility that originates from the consumption sector plays the “traditional” role of depressing the real economy and stock prices, whereas volatility that originates from the investment sector boosts pric...
