The construct of entrepreneurial alertness has been gaining considerable interest from academics because it is at the heart of the entrepreneurial process. Consequently, there has been a substantial increase in the number of academic papers over the years. However, this is a highly fragmented field of research that aggregates contributions from researchers in the fields of economics and strategy, entrepreneurship, and psychology. Also, in recent decades, the concept of entrepreneurial alertness has been studied from different perspectives, being considered, on one hand, as cognitive capacity, a dynamic capacity or a skill of the entrepreneur and, on the other hand, as an organizational factor that affects a company’s performance and a source of competitive advantage. The analysis reveals a set of future research avenues that may contribute to the development of the entrepreneurial alertness research field.
