Financial development and productive efficiency in OECD countries: An exploratory analysis

The recent literature provides evidence for a positive relationship between financial deepening and growth but is quite silent on the exact channels through which it materializes. Theory suggests that production efficiency should be one of those main channels. We attempt to capture this channel by modeling productive efficiency explicitly and constructing efficiency frontiers using data envelopment analysis. We apply this procedure to consider whether financial development creates productive efficiency gains in the industrialized OECD countries. Our results show that financial development contributes to productive efficiency. However, this effect weakens over time during the period under scrutiny. Moreover, we find that the effects of financial deepening on productive efficiency depend on the degree of efficiency already achieved.
