One product, two prices: the border effect in retail prices

(Why) do prices and inflation rates differ within the euro area? We study the relevance of a national border for grocery prices in the otherwise homogenous and highly integrated border region between Austria and Germany. Using transaction data on prices and quantities from a large household panel survey, we compare the prices of identical products within a narrow band along the border. We find large assortment and price differences between the two countries. Even within multinational retail chains the prices of identical products on each side of the border differ on average by about 21%.

Understanding the impact of COVID-19 supply disruptions on exporters in global value chains

We assess the impact of the pandemic and the ensuing disruptions to global value chains (GVCs) on exporting firms. We find that firms’ participation in GVCs increased their vulnerability to the pandemic shock, in terms of export sales and probability of survival. Firms further downstream in GVCs were more severely affected by supply disruptions. At the same time, our results suggest that exporting firms benefited from sourcing their core inputs from different countries, supporting the hypothesis that diversification in global value chains fosters supply chain resilience.

Recent changes in consumers’ medium-term inflation expectations – a detailed look

In this article we exploit the richness and flexible design of the CES to explore in detail recent changes in consumers’ medium-term inflation expectations. The data suggest that over the course of 2022 these expectations became less well anchored around the ECB’s 2% inflation target. By taking the necessary actions and actively communicating how monetary policy is contributing to stabilising future inflation, the ECB can help strengthen public trust and prevent recent price and cost shocks from having longer-lasting inflationary effects.

The safe asset potential of EU-issued bonds

A safe asset is of high credit quality, retains its value in bad times and is traded in liquid markets. We show that bonds issued by the European Union (EU) are widely considered to be of high credit quality, and that their yield spread over German Bunds remained contained during the 2020 COVID-19 pandemic recession. Recent issuances under the EU’s SURE and NGEU initiatives helped improve EU bonds' market liquidity from previously low levels, also reducing liquidity risk premia. Eurosystem purchases and holdings of EU bonds did not impair market liquidity.

Model-based regulation: lending in times of Covid

When the coronavirus (COVID-19) pandemic struck, it was vital for many firms to retain access to funding from banks. In order to calculate their capital requirements, banks measure borrowers’ credit risk using either “their own”, internal ratings-based (IRB) models, or a standardised approach. This analysis examines whether model-based bank regulation constrained lending during the COVID-19 crisis. Results show that banks using their own models extended less credit than banks using a standardised approach.

Financial stability and macroprudential regulation under diagnostic expectations

Recent empirical findings (Bordalo et al., 2018, 2019; Greenwood et al., 2022) have vindicated the view thatsystemic risk in financial markets is also influenced by cognitive misperceptions about future economicdevelopments in addition to being influenced by financial frictions. Most of the literature on macroprudentialregulation, nonetheless, has omitted those misperceptions and instead has derived policy implicationsassuming rational expectations.

Cold hard (digital) cash: the economics of central bank digital currency

Central banks around the world are exploring the case for central bank digital currency (CBDC) – essentially a digital version of cash. In this article, we provide an overview of the economics of CBDC (Ahnert et al., 2022a). First, we outline the economic forces that shape the rise of digital money and motivate the current debate. We then look at the implications for monetary policy and financial stability before discussing policy issues and challenges. Finally, we highlight several areas where our understanding of digital money could be improved by further research.
