This paper studies the entry strategies of firms on risky markets. We focus on markets where demand is affine and cost is linear, moreover, the demand includes a normally distributed random variable. In such a model, we show that the leader's strategy changes with the level of market risk even when firms are risk neutral. Therefore, the availability of future information for a Stackelberg follower has a feedback effect on the leader's strategy. We also show that compared with traditional markets with no risk, the basic trade-off between flexibility and pre-commitment is only slightly changed in the qualitative game where firms are free to choose when to enter the market.
