Location Choices under Strategic Interactions

The literature on location choices has mostly emphasized the impact of location and firm characteristics. However, most industries with a significant presence of multi-location firms are oligopolistic in nature, which suggests that strategic interaction among firms plays an important role in firms' decision-making processes. This paper explores how strategic interaction among competitors affects firms' geographic expansion across time and markets. Specifically, we build a model in which two firms that differ in their capabilities enter sequentially into two markets with different potentials for profit. The model is solved using game theory under three learning scenarios that capture the ability of a firm to transfer its capabilities across markets: no learning, local learning, and global learning. Three equilibrium strategies arise: accommodate, marginalize, and collocate. We identify how these strategies emerge depending on the tradeoff between the opportunity costs of absence (giving competitors a lead in a market) and the entrenchment benefits (the cost advantage firms develop through learning-by-doing when they enter early). Both the opportunity costs of absence and the entrenchment benefits vary according to initial relative firm capabilities, relative market profitability, and learning rates. Our model offers a comprehensive approach to understanding the drivers of firm location choices by modeling not only the impact of location and firm heterogeneity, but also the strategic interaction among firms.
