WELFARE GAINS FROM MACRO-HEDGING
Abstract
Macro-hedging is one of the most important issues in hedging, but there are very few studies on the welfare impact of macro-hedging. To bridge a gap in the literature of macro-hedging, this paper introduces a method that generalizes and extends existing models of macro-hedging in several significant ways. We first assume the existence of basis risk in a small country to hedge in futures markets instead of forward contracts and relax the full-hedging assumption. We use the quantity being hedged in futures contracts as a decision variable. We also relax the restrictive assumption regarding the form of the spot price. We then derive the formula to estimate the welfare gain which can be easily implemented in any empirical case. In contrast to quasi-simulation being used in some existing approaches, our proposed method can be used for any real data, including future data, but existing methods in the literature cannot. Our approach is for investors for their investment decision-making when they use macro-hedging as their trading strategy.
