Toby Daglish and Nimesh Patel discuss the rationale behind banks charging break-fees to recoup their losses as a result of customers prepaying loans. Next they chart the historical levels of these for New Zealand. Lastly they develop a model which allows for fluctuations both in banks' wholesale...

We present a closed form solution for the optimal hedging strategy in discrete time of an option whose underlying security follows the Heston Stochastic Volatility process. Our Monte Carlo simulations indicate that this significantly improves hedging performance at weekly and longer hedging...

It is common practise in industry for traders to use copula models combined with observed market prices to calculate implied correlations for firm defaults. The actual feasibility of this calculation depends on the assumption that there is a one-to-one mapping between values of CDO tranches and...

We explore calibration of single factor no-arbitrage short rate models to yield and volatility information. We note that the calculation of Arrow-Debreu prices for interest rate securities is analogous to solving the Kolmogorov Forward Equation. This insight allows us to implement implicit...

This paper models a spectrum auction as a multi-unit auction where participantsuse the goods purchased to participate in a constrained multi-good downstream market. We use dynamic programming techniques to solve for the optimal bidding strategy for firms in a clock auction. Firms often value...

Toby Daglish's presentation at the Reserve Bank of NZ, May 2012.

This paper proposes a fully-specified equilibrium approach which provides both financial and utility metrics for comparing alternative beliefs about the conditional distribution of a stock price. In this paper we focus on differences in volatility dynamics which are inputs to investors'...

This paper studies residential, commuting and car ownership decisions in the Greater Wellington Region of New Zealand. We establish an estimation methodology that is robust to endogeneity between house prices and residential decisions. The paper also makes extensive use of Geographic Information...

We examine the decision to prepay a fixed rate mortgage in the UK Canada Ireland Australia and New Zealand. These countries are characterised by having substantial fees which are associated with breaking a fixed rate mortgage. We develop a model which allows for fluctuations both in banks'...

Electricity is a non-storable commodity frequently traded in complex markets characterized by oligopolistic structures and uniform-price auctions. These particularities confer to electricity prices idiosyncratic patterns not addressed by the usual commodity pricing literature. This paper allows...
