- Abstract
- We study whether it is desirable for the central bank to supply reserves abundantly, i.e. beyond the level that satisfies financial institutions’ aggregate liquidity needs. Using a theoretical framework, we demonstrate that abundant reserves would help fulfil the private sector’s demand for safe and liquid assets, because reserves affect financial institutions’ leverage constraints. More specifically, systematic central bank purchases of medium-term government bonds from financial institutions would relax those institutions’ leverage constraints and allow them to expand their balance sheets and issue more private liquidity, in the form of deposits. However, a very large increase in the average size of its balance sheet would expose the central bank to the risk of large financial losses. On balance, only amoderately larger supply of reserves than the level that satisfies financial institutions’ aggregate liquidity needs appears desirable.

- Abstract
- We compare supermarket price setting in the US and the euro area and assess its impact on food inflation. We introduce a novel scanner dataset of Germany, the Netherlands, France, and Italy (EA4) and contrast it with an equivalent dataset from the US. We find that both higher frequency and stronger state dependence of price changes contribute to higher flexibility of supermarket inflation in the US relative to the euro area. We argue that the driving force behind both factors is higher cross-sectional volatility in the US. Larger product-level fluctuations both force retailers to adjust prices more frequently and increase price misalignments, which increase the selection of large price changes. [...]

- Abstract
- The coronavirus (COVID-19) pandemic caused a deep recession globally, as well as in the euro area, accompanied by a steep decline in inflation rates in 2020. This paper reviews some of the main challenges created by the pandemic for inflation measurement and provides micro price data analysis of how price setting has reacted to the strong COVID-19 shock. For this purpose, we use three different, but complementary, microdata sources for specific countries and sectors: micro price data underlying the official consumer price indices in Germany, Italy, Latvia and Slovakia; (scanner) data from German and Italian supermarkets; and online (web-scraped) prices for Poland. A common finding of the micro price studies in this paper is that state dependence significantly contributed to the price-setting response to the COVID-19 shock. Nevertheless, the extent and degree of responses varies widely by sector and even country, also depending on the severity of the pandemic situation.

- Abstract
- This paper documents five stylised facts relating to price adjustment in the euro area, using various micro price datasets collected in a period with relatively low and stable inflation. First, price changes are infrequent in the core sectors. On average, 12% of consumer prices change each month, falling to 8.5% when sales prices are excluded. The frequency of producer price adjustment is greater (25%), reflecting that the prices of intermediate goods and energy are more flexible. For both consumer and producer prices, cross-sectoral heterogeneity is more pronounced than cross-country heterogeneity. Second, price changes tend to be large and heterogeneous. For consumer prices, the typical absolute price change is about 10%, and the distribution of price changes shows a broad dispersion. For producer prices, the typical absolute price change is smaller, but nevertheless larger than inflation. Third, price setting is mildly state-dependent: the probability of price adjustment rises with the size of price misalignment, mainly reflecting idiosyncratic shocks, but it does not increase very sharply. Fourth, for both consumer and producer prices, the repricing rate showed no trend in the period 2005-19 but was more volatile in the short run. Fifth, small cyclical variations in frequency did not contribute much to fluctuations in aggregate inflation, which instead mainly reflected shifts in the average size of price changes. Consistent with idiosyncratic shocks as the main driver of price changes, aggregate disturbances affected inflation by shifting the relative number of firms increasing or decreasing their prices, rather than the size of price increases and decreases.

- Abstract
- We use microdata to estimate the strength of price selection { a key metric for the effect of monetary policy on the real economy. We propose a product-level proxy for mispricing and assess whether products with larger mispricing respond with a higher probability to identified monetary and credit shocks. We find that they do not, suggesting selection is absent. Instead, we detect state-dependent adjustment on the gross extensive margin. Our results are broadly consistent with second-generation state-dependent pricing models and sizable effects of monetary policy on the real economy.

- Abstract
- We explain the role of the Phillips Curve in the analysis of the economic outlook and the formulation of monetary policy at the ECB. First, revisiting the structural Phillips Curve, we highlight the challenges in recovering structural parameters from reduced-form estimates and relate the reduced-form Phillips Curve to the (semi-)structural models used at the ECB. Second, we identify the slope of the structural Phillips Curve by exploiting cross-country variation and by using high-frequency monetary policy surprises as instruments. Third, we present reduced-form evidence, focusing on the relation between slack and inflation and the role of inflation expectations. In relation to the recent weakness of inflation, we discuss the role of firm profits in the pass-through from wages to prices and the contribution of external factors. Overall, the available evidence supports the view that the absorption of slack and a firm anchoring of inflation expectations remain central to successful inflation stabilisation.

- Abstract
- This paper examines the interactions of macroprudential and monetary policies. We find, using a range of macroeconomic models used at the European Central Bank, that in the long run, a 1% bank capital requirement increase has a small impact on GDP. In the short run, GDP declines by 0.15-0.35%. Under a stronger monetary policy reaction, the impact falls to 0.05-0.25%. The paper also examines how capital requirements and the conduct of macroprudential policy affect the monetary transmission mechanism. Higher bank leverage increases the economy's vulnerability to shocks but also monetary policy's ability to offset them. Macroprudential policy diminishes the frequency and severity of financial crises thus eliminating the need for extremely low interest rates. Countercyclical capital measures reduce the neutral real interest rate in normal times.

- Abstract
- This paper provides a detailed description of an extended version of the ECB’s New Area-Wide Model (NAWM) of the euro area (cf. Christoffel, Coenen, and Warne 2008). The extended model—called NAWM II—incorporates a rich financial sector with the threefold aim of (i) accounting for a genuine role of financial frictions in the propagation of economic shocks and policies and for the presence of shocks originating in the financial sector itself, (ii) capturing the prominent role of bank lending rates and the gradual interest-rate pass-through in the transmission of monetary policy in the euro area, and (iii) providing a structural framework useable for assessing the macroeconomic impact of the ECB’s large-scale asset purchases conducted in recent years. In addition, NAWM II includes a number of other extensions of the original model reflecting its practical uses in the policy process over the past ten years.

- Abstract
- Central bank announcements simultaneously convey information about monetary policy and the economic outlook. We use changes in interest rate expectations and stock prices around the time of policy announcements to disentangle the impact of news about monetary policy from that of news about the economic outlook. We find that both play a significant role in the dynamics of inflation and economic growth, and that controlling for news about the economy helps us to measure more accurately the transmission of monetary policy.

- Abstract
- Central bank announcements simultaneously convey information about monetary policy and the central bank’s assessment of the economic outlook. This paper disentangles these two components and studies their effect on the economy using a structural vector autoregression. It relies on the information inherent in high-frequency comovement of interest rates and stock prices around policy announcements: a surprise policy tightening raises interest rates and reduces stock prices, while the complementary positive central bank information shock raises both. These two shocks have intuitive and very different effects on the economy. Ignoring the central bank information shocks biases the inference on monetary policy non-neutrality. We make this point formally and offer an interpretation of the central bank information shock using a New Keynesian macroeconomic model with financial frictions.

- Abstract
- Stable and well-anchored longer-term inflation expectations bolster the ability of the European Central Bank (ECB) to achieve its medium-term inflation objective. This article assesses the effectiveness of non-standard monetary policy measures in guiding longer-term inflation expectations in an environment where standard interest rate policy approaches the lower bound. This causal channel is identified by looking at the change in five-year-ahead inflation expectations following announcements of non-standard measures in the period since 2013. The results suggest that non-standard measures, and in particular the asset purchase programme (APP), were conducive to preventing a potential unanchoring of longer-term inflation expectations.

- Abstract
- This paper analyses the effects of the European Central Bank’s expanded asset purchase programme (APP) on yields and on the macroeconomy, and sheds some light on its trans-mission channels. It shows, first, that the January 2015 announcement of the programme has significantly and persistently reduced sovereign yields on long-term bonds and raised the share prices of banks that held more sovereign bonds in their portfolios. This evidence is consistent with versions of the portfolio rebalancing channel acting through the removal of duration risk and the relaxation of leverage constraints for financial intermediaries. It then presents a stylised macroeconomic model that incorporates the aforementioned trans-mission channels. The model suggests that the macroeconomic impact of the programme can be expected to be sizable.

- Abstract
- How do prices react to large aggregate shocks? Our new micro-data evidence on value-added tax changes shows that prices react (i) flexibly and (ii) asymmetrically to large positive and negative shocks. We use it to quantitatively evaluate the performance of prominent pricing models. We show that standard time-dependent models are unable to reproduce either of these facts. A realistically calibrated state-dependent menu cost model, in contrast, is successful in matching the observed price responses. Its success lies in its ability to capture the exploding fraction of price changes for large shocks. The evidence facilitates comparison of different menu cost models and raises doubts on alternative pricing models with information or search frictions as sole reasons for price rigidity.
