We begin by posing questions about the basic definition of FMA and whether advantage should be measured in terms of profit, market share or business survival — which often yield conflicting results. We then probe the related question of duration — over what period of time must superior performance be sustained to constitute first mover advantage? Next we consider problems of identifying the starting date of a market and the basic question of how markets should be defined. Last, we consider a potentially important type of sample selection bias that has largely been overlooked. We conclude by assessing recent progress in entry order research.
