This article derives a model of self-regulation where banks issue insurance products to hedge their own leverage ratio. This approach is an alternative policy to Basel regulation for controlling systemic risk without increasing equity level.Then, we construct two insurability indicators...

This paper revisits the pricing of options, in a context of financial stress, when the underlying asset's returns displays skewness and excess kurtosis. For that purpose, we use a Cornish-Fisher transformation for valuing option contracts with an exact formula allowing for heavy-tails.An...

This article adopts the asymmetric DCC with one exogenous variable (ADCCX) model developed by Vargas (2008), by updating the concept of ‘volatility surprise' to capture cross-market relationships. Current methods for measuring spillovers do not focus on volatility interactions, and neglect...

This article derives a model of self-regulation where banks issue insurance products to hedge their leverage ratio. This approach is an alternative policy to Basel regulation for controlling systemic risk without increasing equity level. We show some conditions under which the model can be...

The capital structure of banks has become the focus of an extended debate among policymakers, regulators and academics. The seminal Modigliani-Miller (1958) theorem is seen as supportive of regulators' drive to require higher equity capital to banks. This raises the question on to what extent...

Should employers pay their employees better? Although this question might appear provoking because lowering production costs remains a cornerstone of the contemporary economy, we present new evidence highlighting the benefits a company might reap by paying its employees better. We introduce an...

Following seminal works of Knight (1921) and Ellsberg (1961), we distinguish uncertainty from risk and examine the impact of aggregate uncertainty on return dynamics of size and book-to-market ratio sorted portfolios. Using VVIX as a proxy for aggregate uncertainty and controlling for market...
