Using a novel dataset from a large supermarket retailer in a European country that never engages in temporary sales, we establish that prices are actually as sticky as regular prices. Circumventing the debate on whether sales have to be included or excluded from price adjustments, we find...

We provide a quantitative assessment of the impact of imports from low-wage countries (LWCs) on CPI inflation in France during 1994-2014, using detailed micro data on imports and exports. The share of imports from low-wage countries in consumption increased from about 2% to 7%, and resulted in a...

This paper proposes an empirical investigation of the impact of oil price forecast errors on inflation forecast errors for two different sets of recent forecasts data: the median of SPF inflation forecasts for the U.S. and the Central Bank inflation forecasts for France. Mainly two salient...

We characterize the dispersion of grocery prices in France based on a large original data set of prices in more than 1500 supermarkets. On average across products, the 90th percentile of relative prices is 17 percentage points higher than the 10th and the mean absolute deviation from quarterly...

Using CPI micro data for 11 euro area countries covering about 60% of the euro area consumption basket over the period 2010-2019, we document new findings on consumer price rigidity in the euro area: (i) each month on average 12.3% of prices change (vs 19.3% in the United States); when we...

Using micro price data covering the Great Recession period, we document new facts on price rigidity in France: (i) each month, 17% of prices are changed versus 23% in the United States. When sales are excluded, only 14% of prices are modified in France versus 15% in the United States; (ii) the...

This paper presents a simple model of state-dependent pricing that allows identification of the relative importance of the degree of price rigidity that is inherent to the price setting mechanism (intrinsic) and that which is due to the price's driving variables (extrinsic). Using two data sets...

This paper describes a forecasting model of the French consumer price index. Its purpose is to allow for rapid and detailed analysis of recent inflation developments, as well as frequent forecasts. Its characteristics are therefore the following: a small number of equations, a monthly frequency,...

Based upon a large fraction of the price records used for computing the French CPI, we document consumer price rigidity in France. We first provide a methodological discussion of issues involved in estimating average price duration with micro-data. The average duration of prices in the sectors...

This paper uses disaggregated CPI time series to show that a break in the mean of French inflation occurred in the mid-eighties and that the 1983 monetary policy shift mostly accounted for it. CPI average yearly growth declined from nearly 11% before the break date (May 1985) to 2.1% after. No...
