In this paper we present a Markov-Functional hybrid interest rate/foreign exchange model that allows calibration to given market volatility surfaces in both dimensions simultaneously. This is achieved by extending the approach introduced by Fries and Rott by a functional for the foreign exchange...

This paper highlights a framework for analysing dynamic hedging strategies under transaction costs. First, self-financing portfolio dynamics under transaction costs are modelled as being portfolio affine. An algorithm for computing the moments of the hedging error on a lattice under portfolio...

This paper investigates volatility persistence in Southern and East African stock markets taking into account the rate of volatility decay. Generalised autoregressive conditional heteroscedaticity (GARCH) and GARCH-in-mean (GARCH-M) models are used to estimate volatility persistence and risk...

We test for the presence of a systematic tail risk premium in the cross-section of expected returns by applying a measure on the sensitivity of assets to extreme market downturns, the tail beta. Empirically, historical tail betas help to predict the future performance of stocks under extreme...

Presentation to the 18th Annual Hyman P. Minsky Conference on the State of the U.S. and World Economies—“Meeting the Challenges of the Financial Crisis”

The dangers of shouting ``fire'' in a crowded theater are well understood, but the dangers of rushing to the exit in the financial markets are more complex. Yet, the two events share several features, and I analyze why people crowd into theaters and trades, why they run, what determines the...

We use the returns on a set of international financial securities to identify exogenous shocks to the Canadian federal surplus. We find that a large portion of the variation in the surplus can be replicated by a linear combination of these returns and that the rising debt observed in the 1980s...

Traditional capital budgeting models price only systemic risk. However, insurers and banks seek to manage their total risk. With the help of modern information systems and information technology, bankers and insurers are able to get timely information on the risk exposures of their multiple...
