Many regulations that affect firms and banks in the economy are based on size thresholds. We develop a model that shows that such regulations distort risk-taking incentives, providing above-threshold firms with greater incentives to take risk and below-threshold firms the opposite. Risk...

This paper evaluates the model risk of models used for forecasting systemic and market risk. Model risk, which is the potential for different models to provide inconsistent outcomes, is shown to be increasing with market uncertainty. During calm periods, the underlying risk forecast models...

The financial crisis of 2008 focused increasing attention on corporate America and, in particular, the risk-taking behavior of large financial institutions. A growing appreciation of the “public” nature of the corporation resulted in a substantial number of high profile enforcement actions....

Choosing a proper external risk measure is of great regulatory importance, as exemplified in the Basel II and Basel III Accord which use Value-at-Risk (VaR) with scenario analysis as the risk measures for setting capital requirements. We argue a good external risk measure should be robust with...

The incremental risk charge (IRC) is a new regulatory requirement from the Basel Committee in response to the recent financial crisis. Notably few models for IRC have been developed in the literature. This paper proposes a methodology consisting of two Monte Carlo simulations. The first Monte...

This article provides an in-depth analysis of the pricing and structuring of contingent convertibles (CoCos) with extension risk. Under the new regulatory Basel III framework, CoCo bonds can be categorised as either belonging to the Additional Tier 1 or Tier 2 capital category. The Tier 1 CoCo...

PurposeThe purpose of this paper is to examine the effects of bank mergers on systemic and systematic risks on the relative merits of product and market diversification strategies. It also observes determinants of M&A deals criteria, product and market diversification positioning, crisis...

The paper provides an axiomatic characterization of dynamic risk measures for multi-period financial positions. For the special case of a terminal cash flow, we require that risk depends on its conditional distribution only. We prove a representation theorem for dynamic risk measures and...

Through the lens of market participants' objective to minimize counterparty risk, we investigate central clearing in derivatives markets, and its interaction with systematic risk, portfolio directionality, and loss sharing. Previous studies suggest that central clearing always reduces...

Through the lens of market participants' objective to minimize counterparty risk, we provide an explanation for the reluctance to clear derivative trades in the absence of a central clearing obligation. We develop a comprehensive understanding of the benefits and potential pitfalls with respect...
