The authors consider risk-neutral valuation of a contingent claim under bilateral counterparty risk using the well-known reduced-form approach.
In this paper, the author builds dynamic networks based on correlation and transfer entropy, using both the log returns and the volatilities of 97 stock market indexes from various parts of the world between 2000 and 2016
In this paper the authors study insolvency cascades in an interbank system, in which banks are permitted to insure their loans with credit default swaps sold by other banks.
Lifecycle investing with the profitable dividend yield strategy: simulations and nonparametric analysis
Using simulations, the author shows that life-cycle investing implemented on highly profitable and high dividend yield stocks (the profitable dividend yield strategy) provides a compelling solution to the suboptimality problem by leveraging on the…
This paper considers the problem of enhancing an investment activity by regularly adding an option trade to the portfolio mix and presented results for the single underlier of the S&P 500 index, with the underlying activity being either long the index or…
The authors present a methodological framework for quantifying interdependencies in the global market and for evaluating risk levels in the worldwide financial network.
The purpose of this paper is to review the literature on asset price bubbles to study the impact that the existence of bubbles has on standard risk management methodologies.
In this paper, the author presents an easy-to-implement, fast and accurate method for approximating extreme quantiles of compound loss distributions (frequency + severity), which are commonly used in insurance and operational risk capital models.
This paper studies tiering in the case of a national payment system in an emerging economy: the large-value payment system Sistemas de Cuentas de Depósito (CUD, the Spanish acronym for the Deposit Accounts System) operated by the Colombian central bank.
In this paper, the authors answer three questions about the appropriate allocation of nondefault losses at central counterparties.
Estimating “hedge and auction” liquidation costs in central counterparties: a closeout risk approach
