This paper compares parametric and non-parametric estimates of productivity change in European banking between 1994 and 2000. Productivity change has also been further decomposed into technological change, or change in best practice, and efficiency change. Both the parametric and non-parametric approaches consistently identify those systems that have benefited most (and least) from productivity change during the 1990s. The results also suggest that (where found) productivity growth has mainly been brought about by improvements in technological change and there does not appear to have been `catch-up' by non-best-practice institutions. Competing methodologies sometimes identify conflicting findings for the sources of productivity for individual years. However, the two approaches generally do not yield markedly different results in terms of identifying the components of productivity growth in European banking during the 1990s.

This paper investigates the dynamics between the financial freedom counterparts of the economic freedom index drawn from the Heritage Foundation database and bank efficiency levels. We rely on a large sample of commercial banks operating in the 27 European Union member states over the 2000s. After estimating bank-specific efficiency scores using Data Envelopment Analysis (DEA), we develop a truncated regression model combined with bootstrapped confidence intervals to test our main hypotheses. Results suggest that the higher the degree of an economy’s financial freedom, the higher the benefits for banks in terms of cost advantages and overall efficiency. Our results also show that the effects of financial freedom on bank efficiency tend to be more pronounced in countries with freer political systems in which governments formulate and implement sound policies and higher quality governance.
