Recent research on the pioneering advantage has shown that consumers often prefer pioneering brands to follower brands. Recent research on consumer choice suggests that information about brands is filtered through a series of sequential cognitive processes. This study attempts to integrate these two separate lines of research by investigating the effects of pioneering on each stage of the multistage decision process. A within-subjects longitudinal experiment was conducted to simulate brand order of entry into a new market. We also developed a sequential logit model to isolate the direct impact of pioneering on each stage of the decision process while controlling for indirect effects of pioneering on previous stages. The results revealed that the pioneering brand (vs. followers) is more likely to be retrieved, considered, and selected. Moreover, the results revealed that consumers are more likely to bypass consideration set formation when the choice decision is simple (vs. complex). Theoretical and practical implications of the results are discussed.
