We investigate the extent to which competitors’ presence in a given export market has an impact on a firm's decision to enter such a market and, more precisely, under what conditions imitation is more likely to take place. We show that firms with greater export knowledge are more likely to enter those countries where their competitors are already present. Furthermore, experiential knowledge seems necessary to absorb valuable information provided by the presence of competitors in those markets. Thus, imitation should not be regarded as the option best suited for firms with reduced expertize that follow blindly their competitors into new markets. Through a panel analysis of Brazilian exporters during the 2001–11 period, our study contributes to research on market entry decisions, especially stressing the critical role of prior relevant knowledge in facilitating imitation among players.
