Fluctuations in commodity prices are a major concern to many market participants. This paper uses realized volatility … methods to calculate daily volatility and correlation estimates for three grain futures prices (corn, soybean and wheat). The … realized volatility estimates exhibit the properties consistent with the stylized facts observed in earlier studies. According …

This paper investigates whether the risk-return relation varies, depending on changing market volatility and up …/down market conditions. Three market regimes based on the level of conditional volatility of market returns are specified - 'low … premium in the three market volatility regimes is priced. These significant results are uncovered only in the pricing model …

This paper proposes a new test for simultaneous intraday jumps in a panel of high frequency financial data. We utilize intraday first-high-low-last values of asset prices to construct estimates for the cross-variation of returns in a large panel of high frequency financial data, and then employ...

We review the past 25 years of time series research that has been published in journals managed by the International Institute of Forecasters (Journal of Forecasting 1982-1985; International Journal of Forecasting 1985-2005). During this period, over one third of all papers published in these...

Empirical tests of option pricing models are joint tests of the 'correctness' of the model, the efficiency of the market and the simultaneity of price observations. Some degree of nonsimultaeity can be expected in all but the most liquid markets and is therefore evident in many non-US markets....

In this paper Bayesian methods are applied to a stochastic volatility model using both the prices of the asset and the … price of volatility risk are produced via a hybrid Markov Chain Monte Carlo sampling algorithm.

In this paper we apply Bayesian methods to estimate a stochastic volatility model using both the prices of the asset … and the prices of options written on the asset. Implicit posterior densities for the parameters of the volatility model …, for the latent volatilities and for the market price of volatility risk are produced. The method involves augmenting the …
