We document the importance of import prices and domestic profits as a counterpart to the recent increase in euro area inflation. Through a novel consumption deflator decomposition, we show that import prices account for 40 percent of the average change in the consumption deflator over 2022Q1 – 2023Q1, while domestic profits account for 45 percent. The increase in nominal profits was largest in sectors benefiting from increasing international commodity prices and those exposed to recent supply-demand mismatches. While the results show that firms have passed on more than the nominal cost shock, and have fared relatively better than workers, the limited available data does not point to a widespread increase in markups. Looking ahead, assuming nominal wage growth of around 4.5 percent over 2023-24 – slightly below the level seen in Q1 2023 – and broadly unchanged productivity, a normalization of the profit share to the average level over 2015-19 will be necessary to achieve a convergence of inflation to target over the next two years. Monetary policy will thus need to remain restrictive to anchor expectations and maintain subdued demand such that workers and firms settle on relative price setting that is consistent with disinflation.

This article explores the relationship between labor costs and price inflation under two conditions. Firstly, with linear assumption and classical techniques. Secondly, without assuming linearity, by a novel non-parametric machine learning method, namely gradient boosting. With quarterly data from 1996 to 2022 for V4 countries, we find linear and non-linear dependency between labor cost and price inflation. However, the magnitude of the connection is country-specific and changes over time. Our findings indicate that a significant linear relationship between considered variables does not lead to the higher predictability power of labor cost in a non- parametric model, which predicts inflation. Even opposed, the Czech Republic, the country with the highest correlation between unit labor cost(ULC) and deflator, shows better prediction in a case when the ULC is not in the set of independent variables. This fact highlights the importance of non-linearity for the inflation model.

Wages have been rising faster than productivity in many European countries for the past few years, yet signs of underlying consumer price pressures remain limited. To shed light on this puzzle, this paper examines the historical link between wage growth and inflation in Europe and factors that influence the strength of the passthrough from labor costs to prices. Historically, wage growth has led to higher inflation, but the impact has weakened since 2009. Empirical analysis suggests that the passthrough from wage growth to inflation is significantly lower in periods of subdued inflation and inflation expectations, greater competitive pressures, and robust corporate profitability. Thus the recent pickup in wage growth is likely to have a more muted impact on inflation than in the past.

This book collects results from ad hoc surveys on firms pricing behavior conducted in 2003 and 2004 by nine National central banks of the Euro area in the context of a joint research project (Eurosystem Inflation Persistence Network). These surveys have proved to be an efficient way to test theories on the pricing strategies of economic agents, documenting, in qualitative terms, the underlying rationale of the observed pricing patterns. The book provides an unprecedented amount of information from more than 11,000 euro area firms, addressing issues such as the relevance of nominal and real rigidities, the information set used by firms in the price setting process, the strategy followed to review prices, the frequency of both price reviews and price changes, the reasons underlying price stickiness, and asymmetries in price adjustment. It also compares results for the euro area to those obtained for other countries by similar studies. Finally, it draws the main implications for theoretical modeling and for monetary policy.

We provide evidence on the fit of the New Phillips Curve (NPQ for the Euro area over the period 1970-1998, and use it as a tool to compare the characteristics of European inflation dynamics with those observed in the U.S. We also analyze the factors underlying inflation inertia by examining the cyclical behavior of marginal costs, as well as that of its two main components, namely, labor productivity and real wages. Some of the findings can be summarized as follows: (a) the NPC fits Euro area data very well, possibly better than U.S. data, (b) the degree of price stickiness implied by the estimates is substantial, but in line with survey evidence and U.S. estimates, (c) inflation dynamics in the Euro area appear to have a stronger forward- looking component (i.e., less inertia) than in the U.S., (d) labor market frictions, as manifested in the behavior of the wage markup, appear to have played a key role in shaping the behavior of marginal costs and, consequently, inflation in Europe.

This paper estimates the importance of the cost channel of monetary policy in a New Keynesian model of the business cycle. A model with nominal rigidities is extended by assuming that a fraction of firms need to borrow money to pay their wage bill. Hence, monetary policy tightenings increase effective unit labor costs of production, and might imply an increase in inflation. The model explains the joint dynamics of output, inflation, real wages, and interest rates, and is estimated using a Bayesian framework and data for the United States and the euro area. The main result is that cost channel effects are absent in both cases. Moreover, it is not possible to obtain a "price puzzle" type of behavior from estimated impulse responses to monetary policy shocks.
