Triphon Phumiwasana Milken Institute Conference on Political Economic Indicators and International Economic Analysis: Measuring Quality and the Quality of Measures October 12-13, 2007 Diversified Financial Structure: Implications for Economic Growth and Stability

Why Study Financial Structure? “Diversity within the financial sector provides insurance against a financial problem turning into economy-wide distress” Alan Greenspan, 1999 “It is the financial services themselves that matter more than the form of their delivery. … It is better to focus policies on development of a solid infrastructure, rather than specific structures.” World Bank, 2001

Motivation   Increasing number of financial market reforms in Latin America and Asia, encompassing the stock, bond and derivative markets   Long economic downturns in major bank-based systems—Japan and Germany   Empirical Evidence: Mixed  No cross-country relationship between financial structure and growth (Levine, 2002).  Market-based systems outperform bank-based systems among developed countries, while bank-based systems outperform market-based systems among developing countries (Tadesse, 2002).  Bank-based systems promote long-run growth better than market-based systems (Arestis et al, 2001)   Bank-based systems can reduce the impact of interest rate shocks.

Measuring Financial Structure “Because financial structure is determined by a combination of financial instruments and financial institutions, several aspect must be taken into account and given quantitative expression when ever possible. They are:  the relation of total financial assets to total tangible assets;  the distribution of total financial assets and liabilities among various types of financial instruments;  and the position of financial assets and liabilities in the accounts of the various economic sectors. Each of these stock relations has a corresponding flow aspect, doubling the number of relation relevant for the study of financial structure” Raymond Goldsmith Financial Structure and Development, 1969

How to Define Financial Structure? Financial institutions vs. financial markets? Banks vs. stock market? Insurance companies? Bonds? Derivatives? Private equity? Hedge funds? Personal funding? Cooperative banks? Microfinance? Domestic vs. cross-border funding? Financial sector: Depth? Activity? Size? Efficiency? The composition of the source of funding of firms in a country?

Composition of Financial Assets Held By Households June 2007 United States $44.3 Trillion Japan $13.5 Trillion Source: Bank of Japan

Simplified Version of “Financial Structure”   Examine the two widely used channels which connect saving to investment   Classification of channels: market-based vs. bank-based systems   Most evidence shows that finance promotes growth, but do channels of finance matter?

Why Do Bank-Based Systems Develop First?   High initial cost to develop financial infrastructure for broader market development.   Banks lobby to keep out competitor.

Role of Market-Based Systems   Allow portfolio diversification for investors and widening the choice of finance for firms.   “Spare Tire”: At macro level, so long as both systems are not perfectly correlated, having two system may produce a more stable economy.

Factors Effecting Financial Structure Level of Development (Boyd and Smith, 1996; Gurley and Shaw, 1955) Legal Origin (La Porta et al,1998) Laws and Regulations (Levine, 2002; World Bank, 2001)) Demographics and Human Capital (Black, 2002)

Common Measurements of Financial Structure  Activities: Bank Credit to Private Sector relative to Stock Market Traded Value  Size: Bank Credit to Private Sector (some authors use Bank Assets) relative to Stock Market Capitalization  Efficiency:  Efficiency: Reciprocal of Bank Overhead Cost to Total Asset Multiplied by Stock Market Traded Value / GDP

Estimation Y it = Five-year average GDP Growth X it = Control variables (Initial income, Government Expenditure, Trade and Schooling) B it = Natural log of bank credit to private sector as a share of GDP F it = Financial structure (higher value indicates more bank-based system) I i = Lack of Property rights, Corruption, Costly of Contract Enforcement Z it = Instrumental variables B it (hat) = estimated B it Time-Fixed Effects with Instrumental Variables:

Dependent Variable: Growth of Real GDP Per Capita All Countries Developed Countries Developing Countries

Dependent Variable: Standard Deviation of Growth in Real GDP Per Capita All Countries Developed Countries Developing Countries

Conclusions  Bank-based financial structures in general have a negative impact on growth. The results are stronger for developed countries.  Evidence is inconclusive as to whether a bank-based or market-based system is better for growth for developing countries.

Conclusions  On average, evidence does not indicate that a bank- based system either lowers or increases volatility of growth  Among developed countries, however, a bank-based system is positively associated with higher volatility of growth.  Some evidence exists, however, that for developing countries a bank-based system is negatively associated with volatility of growth.

Suggestions for Future Research  Improve financial structure measurements  Examine whether government ownership of banks affects the relationship between a bank- based financial structure and growth.  Examine the degree to which cross-border financing impacts the domestic structure, and whether the inflow through each channel impacts economic growth differently.  Examine bond market development and growth
