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

10/31/2022 European Central Bank Central banks

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.

Green QE and carbon pricing: looking at potential tools to fight climate change

09/28/2022 European Central Bank Central banks

While there is broad consensus that carbon pricing is an effective instrument for combatting climate change, the potential contribution of central banks is still debated. Central banks around the world have adopted different strategies to consider climate change in their monetary policy frameworks. This article focuses on green quantitative easing (QE). Compared with a carbon tax, we find that green QE would contribute only moderately to reducing global temperatures, while partially crowding out green private investment.

Striking a bargain: narrative identification of wage bargaining shocks

07/27/2022 European Central Bank Central banks

Labour market developments are important drivers of the business cycle and are therefore closely watched by monetary policymakers. One process with significant macroeconomic ramifications are wage negotiations, where workers and employers bargain over the surplus income generated by an employment relationship. Bargaining power determines how this surplus is split between negotiating parties. However, it is unobserved, and can be driven by a number of factors.

Systemic risk and policy interventions: monetary and macroprudential policy

06/24/2022 European Central Bank Central banks

Throughout the world, the global financial crisis fostered the design and adoption of macroprudential policies to safeguard the financial system. This raises important questions for monetary policy, which, by contrast, primarily focuses on maintaining price stability. What, if any, is the relationship between (conventional) monetary policy and macroprudential policy? In particular, how does the effectiveness of macroprudential policies influence the conduct of monetary policy? This article reviews recent theoretical and empirical research addressing these questions.

Europe's growing league of small corporate bond issuers: new players, different game dynamics

06/15/2022 European Central Bank Central banks

While historically only very large firms issued in the European corporate bond market, recent years have seen the entry of many new players: small, private, and unrated issuers. Firm-level data show these new players face different game dynamics. They are disconnected from aggregate market movements and still depend heavily on banks. This means hey could potentially affect financial stability and be less responsive to policy interventions.

Tax thy neighbour: local corporate taxes and consumer prices across German regions

05/27/2022 European Central Bank Central banks

To what extent are corporate taxes passed on to consumers? And more generally, how do wholesaleproducers affect retail prices? Using data from Germany, where individual municipalities set local corporate taxrates, we shed new light on these questions. To estimate the impact of changes in producers’ tax rates onconsumer prices, we link 1,058 tax changes between 2013 and 2017 to changes in the retail prices of morethan 125,000 food and personal care products sold across Germany.
