Risk diversification is the basis of insurance and investment. It is thus crucial to study the effects that could limit it. One of them is the existence of systemic risk that affects all the policies at the same time. We introduce here a probabilistic approach to examine the consequences of its...

Expected Shortfall (ES) has been widely accepted as a risk measure that is conceptually superior to Value-at-Risk (VaR). At the same time, however, it has been criticized for issues relating to backtesting. In particular, ES has been found not to be elicitable which means that backtesting for ES...

This paper proposes a framework for the surveillance of financial institutions' derivatives activities. The designed framework builds on information likely to be collected by financial market regulators for supervisory purposes, and/or information collected by market participants for the purpose...

The increasing ability to trade credit risk in financial markets has facilitated its dispersion across the financial and other sectors. However, specific risks attached to credit risk transfer (CRT) instruments in a market with still-limited liquidity means that its rapid expansion may actually...

The financial turmoil of the late 1990s prompted a broad search for tools and techniques for detecting and preventing financial crises, and more recent episodes of instability have high lighted the importance of continuous monitoring of financial systems as a tool for preventing crises. This...

How to entrench hard-won gains, increase resilience to shocks, and improve growth performance to reduce poverty? As Central America moves forward in regaining macroeconomic stability, these are the challenges. This study analyzes Central America’s real, fiscal, monetary, and financial...

Using a new dataset of bid and offer quotes for credit default swaps, we investigate the relationship between theoretical determinants of default risk and actual market premia using cross sectional regressions. These theoretical determinants are variance risk premia, implied volatility and the...

Through a long-period analysis of the inter-temporal relations between the French markets for credit default swaps (CDS), shares and bonds between 2001 and 2008, this article shows how a financial innovation like CDS could heighten financial instability. After describing the operating principles...

Results from portfolio models for credit risk tell us that loan concentration in certain industry sectors can substantially increase the value-at-risk (VaR). The purpose of this paper is to analyze whether a tractable "infection model" can provide a meaningful estimate of the impact of...
