- Banking firm and hedging over the business cyclePublication . Broll, Udo; Kit, Pong WongThis paper examines the behavior of a banking firm under risk. The banking firm can hedge its risk exposure by trading futures contracts. The banking firm is risk averse and possesses a utility function defined over its end-of-period income and a state variable that denotes the business cycle of the economy. We show that the banking firm optimally opts for an overhedge or an under-hedge, depending on whether the returns on the futures contracts are negatively or positively correlated with the business cycle of the economy, respectively. Thus, the business cycle of the economy is an important determinant in shaping the banking firm’s optimal hedging strategy.
- The impact of inflation risk on forward trading and productionPublication . Broll, Udo; Kit Pong, WongThis paper examines the behavior of a competitive firm that faces joint price and inflation risk. Given that the price risk is negatively correlated with the inflation risk in the sense of expectation dependence, we show that the firm optimally opts for an over-hedge (under-hedge) if the firm’s coefficient of relative risk aversion is everywhere no greater (no smaller) than unity. We show further that banning the firm from forward trading may induce the firm to produce more or less, depending on whether the price risk premium is positive or negative, respectively. While the price risk premium is unambiguously negative in the absence of the inflation risk, it is not the case when the inflation risk prevails. In contrast to the conventional wisdom, forward hedging needs not always promote production should firms take inflation seriously.
