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...

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...

The popular practice of selling market volatility through selling straddles exposes traders and investors to substantial risk, especially in equity markets. The returns can be very lucrative, but the probability of large negative returns far exceeds the probability of large positive returns. In...

This Economic Letter is adapted from a speech delivered by Janet L. Yellen, president and CEO of the Federal Reserve Bank of San Francisco, to the 18th Annual Hyman P. Minsky Conference on the State of the U.S. and World Economies on April 16, 2009, in New York City.

There has been a long debate about whether speculators are stabilizing or not. We consider a model where speculators have a stabilizing role in normal times, but may also provoke large risk panics. The very feature that makes arbitrageurs liquidity providers in normal times, namely their...

Measuring value creation by comparing the RAROC of an exposure (the return on risk capital) with a single institution-wide hurdle rate is inconsistent with the standard theory of financial valuation. We use asset pricing theory to determine the appropriate hurdle rate for such a RAROC...
