The Dunning-Kruger effect and entrepreneurial self-efficacy: How tenure and search distance jointly direct entrepreneurial self-efficacy
研究创业者的任期和搜索距离如何共同影响其自我效能感，发现进行远距离搜索的创业者其自我效能感随任期呈U型变化，而低搜索距离者则相对稳定。
Are people with more experience running an entrepreneurial venture also more confident? How does that confidence look for those who gathered those experiences outside of their comfort zone? This paper advances the entrepreneurial self-efficacy (ESE) literature by integrating the Dunning-Kruger perspective into the experience-ESE relationship, and by conceptualizing experience as a combination of tenure and search distance (a venture searches distantly if its new products are dissimilar to its existing ones). In a unique sample of small businesses, between-entrepreneur analyses reveal a U-shaped association between venture tenure and ESE for entrepreneurs who engage in distant search with their venture, and a relatively stable ESE over venture tenure if distant search is low.
