Different sources of data on “entrepreneurship” have led to contradictory or inconclusive empirical findings on its dynamics (Hoffman and Oxholim, 2006). Country-specific differences may contribute to this problem, as well as varied sources of data used for research. For this reason, we compare datasets from the Global Entrepreneurship Monitor (GEM) and World Bank Group Entrepreneurship Survey (WBGES). The GEM data measures early-stage entrepreneurial activity and the WBGES dataset measures formal business registration. Studies using both datasets have produced contradictory results: No relationship is found between GEM data and administrative barriers to starting a business (van Stel et al, 2007) but a significantly negative effect is found with WBGES data (Klapper et al, 2007).
