The increase in the price of gold between 2002 and 2011 appears to be a candidate for a potential asset price ‘bubble', suggesting that chartists (feedback traders) were highly active in the gold market during this period. Hence, this paper develops and tests empirically several models...

We develop two models for index futures arbitrage that take the financing constraints faced by real-world arbitrageurs into account. Our models predict that the price of an index futures contract and the value of its underlying index should deviate further from their theoretical cost-of-carry...

We formulate a continuous-time model of a deposit taking bank, operating subject to capital adequacy regulation, and where the bank's loans are exposed to default risk. The bank maximises their market value of equity by appropriately controlling loan and equity issuance, dividend payments, and...

We analyse the effect of mean-reverting cash flows on the costs of shareholder-bondholder conflicts arising from partially debt-financed investments. In a partial equilibrium setting we find that such agency costs are significantly lower under mean-reverting (MR) dynamics, when compared to the...

To investigate the effect of short-selling constraints on investor behaviour, we formulate an optimal stopping model in which the decision to cover a short position is affected by two short sale-specific frictions—margin risk and recall risk. Margin risk is introduced by assuming that a short...
