    Long-Run international diversification
    (University College Dublin. Geary Institute, 2015-02-27) ; ;
    Prevailing wisdom in finance suggests long-run investors have a competitive advantage, since they can ride out short-run fluctuations and mispricing, and pursue illiquid investments. This paper investigates if this advantage holds in a portfolio context, examining benefits of international diversification across short- and longrun horizons. Employing a multi-horizon non-parametric filter, increased long-run correlations between international equity markets are detailed, even for synchronized markets. A model replicating the temporal aggregation properties of intermarket correlation is developed, indicating that short-run correlations are downward biased by frictions. Finally, the impact on portfolio allocation is investigated, demonstrating decreased risk reduction benefits in the long-run.

    Commodity Futures Hedging, Risk Aversion and the Hedging Horizon
    (UCD Geary Institute, 2012) ; ;
    This paper examines the impact of investor preferences on the optimal futures hedging strategy and associated hedging performance. Explicit risk aversion levels are often overlooked in hedging analysis. Applying a mean-variance hedging objective, the optimal futures hedging ratio is determined for a range of investor preferences on risk aversion, hedging horizon and expected returns. Wavelet analysis is applied to illustrate how investor time horizon shapes hedging strategy. Empirical results reveal substantial variation of the optimal hedge ratio for distinct investor preferences and are supportive of the hedging policies of real firms. Hedging performance is then shown to be strongly dependent on underlying preferences. In particular, investors with high levels of risk aversion and a short horizon reduce the risk of the hedge portfolio but achieve inferior utility in comparison to those with low risk aversion.
