Introducing a New Broad-based Index of Financial Development

TLDR

Existing research on financial development relies on simple depth measures such as private credit or stock market capitalization, yet these fail to capture its multidimensional nature. This paper introduces nine indices that jointly assess depth, access, and efficiency of financial institutions and markets. The indices are combined into a single overall financial development index. The resulting database covers 183 countries annually from 1980 to 2013, providing a valuable resource for researchers and policymakers.

Abstract

There is a vast body of literature estimating the impact of financial development on economic growth, inequality, and economic stability. A typical empirical study approximates financial development with either one of two measures of financial depth – the ratio of private credit to GDP or stock market capitalization to GDP. However, these indicators do not take into account the complex multidimensional nature of financial development. The contribution of this paper is to create nine indices that summarize how developed financial institutions and financial markets are in terms of their depth, access, and efficiency. These indices are then aggregated into an overall index of financial development. With the coverage of 183 countries on annual frequency between 1980 and 2013, the database should offer a useful analytical tool for researchers and policy makers.
