This paper presents a novel approach to addressing VAT regressivity, by proposing the adoption of a progressive VAT: a single-rate, broad-base, VAT, whereby tax paid on consumption is re-paid to lower income households in real-time, at the moment of purchase. Such a system can effectively...

This paper considers the implementation challenges facing the Basel Committee’s new proposals on bank capital standards. When compared with the existing Capital Accord, the proposals represent a shift across two intersecting dimensions—regulatory versus economic capital, and rules-based...

For almost a decade, the IMF has been using stress tests to identify vulnerabilities across institutions that could undermine the stability of a country's financial system. This working paper focuses on the IMF's experience with stress testing in the Financial Sector Assessment Program (FSAP)....

The paper discusses the limits to market-based risk transfer in the financial system and the implications for the management of systemic long-term financial risks. Financial instruments or markets to transfer and better manage these risks across institutions and sectors are, as yet, either...

The banking crises of the 1990s emphasize the need to model the connections between volatility and the potential losses faced by financial institutions due to correlated market and credit risks. We present a simulation model that explicitly links changes in the financial environment and the...

In this paper, we provide an overview of the concerns surrounding the variations in the calculation of risk-weighted assets (RWAs) across banks and jurisdictions and how this might undermine the Basel III capital adequacy framework. We discuss the key drivers behind the differences in these...

This paper presents a "second-generation" solvency stress testing framework extending applied stress testing work centered on Cihák (2007). The framework seeks enriching stress tests in terms of risk-sensitivity, while keeping them flexible, transparent, and user-friendly. The main...

This paper estimates the costs of ‘de-risking’ scenarios between China and OECD members at the aggregate and sectoral levels. Aggregate large-scale de-risking – reshoring by increasing reliance on domestic production and friend-shoring by reducing imports from specific foreign countries...

This paper presents a simple heuristic measure of tail risk, which is applied to individual bank stress tests and to public debt. Stress testing can be seen as a first order test of the level of potential negative outcomes in response to tail shocks. However, the results of stress testing can be...

This paper investigates the effects of national culture on firm risk-taking, using a comprehensive dataset covering 50,000 firms in 400 industries in 51 countries. Risk-taking is found to be higher for domestic firms in countries with low uncertainty aversion, low tolerance for hierarchical...
