概要	We investigate the product positioning decisions of two firms that enter a market sequentially under a duopoly competition. Two important assumptions are made: differential marginal production costs between the two firms, and endogenous entry timing of a follower in a continuous-time setting. We analyze a standard location-pricing Hotelling game with quadratic transportation costs with the points of departure being that the two firms (i) are allowed to have different (constant) marginal costs; (ii) enter sequentially in a pre-determined order in a market in which the consumers are growing over time; and (iii) are not restricted to choosing positions inside the interval in which consumer preferences are located. For the first mover, the dynamic market growth can give rise to a trade-off between exploiting short-run monopoly and long-run duopoly profits.
