The paper implements a consistent empirical strategy in order to investigate the behaviour of the markup over the cycle and its contribution to inflation movements.We model the price series as I(2) components and use polynomial cointegration in order to recover a long-run price schedule. We do...

The real interest rate gap or IRG - the gap between the short term real interest rate and its "natural" level - is a theoretical concept that has attracted much attention in central banks in recent years. This paper aims at clarifying its practical relevance for monetary policy in real time. For...

This paper proposes new bridge equations for the Monthly Index of Business Activity (MIBA) published by the Banque de France. The MIBA is a forecasting tool for the quarterly GDP growth in France both for the current quarter and the next quarter, originally based on the surveys in the industrial...

Governments and central banks need to have an accurate and timely assessment of Gross Domestic Product's (GDP) growth rate for the current quarter, as this is essential for providing a reliable and early analysis of the current economic situation. This paper presents a series of models conceived...

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...

We study how changes in the value of the steady-state real interest rate affect the optimal inflation target, both in the U.S. and the euro area, using an estimated New Keynesian DSGE model that incorporates the zero (or effective) lower bound on the nominal interest rate. We find that this...

I provide a microfounded theory for one of the oldest, but so far informal, explanations of price rigidity: the kinked demand curve theory. Assuming that some customers observe at no cost only the price of the store they happen to be at gives rise to a kink in firms' demand curves: a price...

Relying on a menu-cost model augmented with a time-dependent (Calvo) component, we investigate the structural sources of cross-sectoral heterogeneity in patterns of price setting. We use a large micro dataset of French consumer prices to estimate the model at the product level for 227 products....

The sensitivity of inflation to domestic slack has declined in developed countries since the mid-1980s. This article shows why this might result from globalization favoring concentration. To do so, I add three ingredients to an otherwise standard general equilibrium two-country new-Keynesian...
