Relating Macro-economic Efficiency to Financial Efficiency: A Comparison of Fifteen OECD Countries Over an Eighteen Year Period

This paper examines the role of the banking sector in the overall economic activity and its contribution to the convergence/divergence in fifteen OECD countries over the time period of 1980–1997. We resort to a non-parametric technique (DEA) and estimate a world wide macro-economic as well as a worldwide banking frontier. We find a very similar pattern in the evolution of banking and macro-economic efficiency. We further study the evolution of the macro-economic and banking productivity and discover, in both cases, convergence over time. Our first finding is that the performance of the banking sector helps to explain the overall economic performance. Our second finding is that the financial orientation of each country constitutes a relevant feature for the last mentioned explanation.
