The Power and Effects of Entrepreneurship Research

This study summarizes and analyzes average statistical power and effect sizes in empirical entrepreneurship research. Results show that statistical power was higher than expected, and was particularly high in studies employing archival measures. Statistical power has also increased over time. Effect sizes were higher than expected, a finding that remained consistent for different levels of analysis and across multiple subdomains. We discuss these findings, compare them to related disciplines, and draw implications for the design of future studies.
