- Abstract
- Climate change and the public policies to arrest it are and will continue reshaping the global economy. This Discussion Paper draws on economic research to identify some key medium- and long-run economic implications of these developments. It explores implications for growth, innovation, inflation, financial markets, fiscal policy, and several socio-economic outcomes. The main message that emerges is that climate change will cause income divergence across individuals, sectors, and regions, adjustment in energy markets, increased inflation variability, financial markets stress, intensified innovation, increased migration, and rising public debt. These challenges appear manageable for EU member states, especially under an early and orderly transition scenario. At the same time, the direction, scope, and speed of economic transformation is subject to large uncertainty due to two separate factors: the wide range of climate scenarios for a given trajectory of greenhouse gas emissions and the exact policy path governments choose, especially in the context of the ongoing Russian aggression in Ukraine.

- Abstract
- What is the effect of Central Bank Digital Currency (CBDC) on financial stability? We answer this question by studying a model of financial intermediation with an endogenously determined probability of a bank run, using global games. As an alternative to bank deposits, consumers can also store their wealth in remunerated CBDC issued by the central bank. Consistent with widespread concerns among policymakers, higher CBDC remuneration increases the withdrawal incentives of consumers, and thus bank fragility. However, the bank optimally responds to the additional competition by offering better deposit rates to retain funding, which reduces fragility. Thus, the overall relationship between CBDC remuneration and bank fragility is U-shaped.

- Abstract
- 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.

- Abstract
- This paper provides a structured overview of the burgeoning literature on the economics of CBDC. We document the economic forces that shape the rise of digital money and review motives for the issuance of CBDC. We then study the implications for the financial system and discuss of a number of policy issues and challenges. While the academic literature broadly echoes policy makers’ concerns about bank disintermediation and financial stability risks, it also provides conditions under which such adverse effects may not materialize. We also point to several knowledge gaps that merit further work, including data privacy and the study of end‐user preferences for attributes of digital payment methods.

- Abstract
- Does the level of deposits matter for bank fragility and efficiency? By augmenting a standard model of endogenous bank runs with a consumption-saving decision, we obtain two novel results. First, depositors’ incentives to run are a function of the level of savings held as bank deposits. Second, a saving externality emerges in that individual depositors do not internalize the effect of their saving decisions on the bank-run probability. As a result, the economy features an inefficient level of savings and bank liquidity provision as well as excessive bank fragility. These results are robust to different sources of bank fragility, as they emerge both when runs are panic- and fundamental-driven.

- Abstract
- Policy rates in advanced economies are unusually low. What effect does this have on bank stability? I identify two competing effects. On the one hand, low rates harm bank profits by squeezing interest margins. On the other hand, they boost the value of long-term assets held by banks. Using a standard banking model, I determine the policy rate level at which these two forces cancel each other out, i.e. the tipping point. Past this tipping point, the net effect of low rates on bank capital is negative. Applying the model to the US economy, I quantify the tipping point in August 2007 as a policy rate of 0.55%.

- Abstract
- This paper studies how interest rates impact bank stability in a standard banking model. There are two opposite effects. While higher rates widen banks’ interest margins, they also reduce the value of their long-term assets. First, the paper characterizes conditions under which an effect dominates. Second, it shows that banking crises are triggered by interest rates crossing a tipping point. Quantitatively, I find that the effect on interest margins is dominant. Hence, low rates are the threat to bank stability. Moreover, I estimate the tipping point at 0.32% for the US economy in the decade before the Global Financial Crisis.
