Diverging against All Odds? Regulatory Paths in Embryonic Stem Cell Research across Western Europe

An interest-driven account of Embryonic Stem Cell Research would, given the considerable financial and scientific concerns, likely predict regulations to converge towards permissive policies. However, across Western Europe, national regulations of embryonic stem-cell research vary considerably, from general bans to permissive policies. There is a lack of systematic accounting for the non-convergence, and the sparse attempts at explanation are contradictory. Drawing on qualitative comparative analysis and configurational causality, we assess the interaction of a number of explanatory factors. Our empirical analysis reveals the importance of one factor in particular, path-dependence, insofar as prior policies on assisted reproduction exert a strong and systematic effect on the subsequent regulation of ESCR.
