We present a model of risk averse exporting firm subject to liquidity constraints. The firm enters an unbiased futuresmarket to hedge exchange rate risk and may not be able to satisfy high margin calls. Then the firm is forced toprematurely liquidate the futures position. We show that preferences and expectations become important for optimumexport and hedging decisions, i.e. separation theorem and full hedge theorem are violated. Furthermore, internationaltrade is affected, for only firms that have sufficient financial resources fully exploid gains from trade.
