Abstract
This paper assumes that the spot price follows a skewed Student t distribution to analyze the effects of skewness and kurtosis on production and hedging decisions for a competitive firm. Under a negative exponential utility function, the firm will not over-hedge (under-hedge) when the spot price is positively (negatively) skewed. The extent of under-hedge (over-hedge) decreases as the forward price increases. Compared with the mean-variance hedger, the producer will hedge more (less) when negative (positive) skewness prevails. In addition, an increase in the skewness reduces the demand for hedging. The effect of the kurtosis, however, depends on the sign of the skewness. When the spot price is positively (negatively) skewed, an increase in kurtosis leads to a smaller (larger) futures position.
