Finance and Growth: Schumpeter Might Be Right

Joseph Schumpeter argued in 1911 that the services provided by financial intermediaries - mobilizing savings, evaluating projects, managing risk, monitoring managers, and facilitating transactions -stimulate technological innovation and economic development. The authors present evidence that supports this view. Examining a cross-section of about 80 countries for the period 1960-89, they find that various measures of financial development are strongly associated with both current and later rates of economic growth. Each measure has shortcomings but all tell the same story: finance matters. They present three main findings, which are robust to many specification tests: The average level of financial development for 1960-89 is very strongly associated with growth for the period. Financial development precedes growth. For example, financial depth in 1960 (the ratio of broad money to GDP) is positively and significantly related to real per capita GDP growth over the next 30 years even after controlling for a variety of country-specific characteristics and policy indicators. Financial development is positively associated with both investment rate and the efficiency with which economies use capital. Much work remains to be done, but the data are consistent with Schumpeters view that the services provided by financial intermediaries stimulate long-run growth.

Financial Development and Economic Growth: Views and Agenda

The author argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth. There is evidence that the financial development level is a good predictor of future rates of economic growth, capital accumulation, and technological change. Moreover, cross-country, case-style, industry level and firm-level analysis document extensive periods when financial development crucially affects the speed and pattern of economic development. The author explains what the financial system does and how it affects, and is affected by, economic growth. Theory suggests that financial instruments, markets and institutions arise to mitigate the effects of information and transaction costs. A growing literature shows that differences in how well financial systems reduce information and transaction costs influence savings rates, investment decisions, technological innovation, and long-run growth rates. A less developed theoretical literature shows how changes in economic activity can influence financial systems. The author advocates a functional approach to understanding the role of financial systems in economic growth. This approach focuses on the ties between growth and the quality of the functions provided by the financial systems. The author discourages a narrow focus on one financial instrument, or a particular institution. Instead, the author addresses the more comprehensive question: What is the relationship between financial structure and the functioning of the financial system?

Africa's Growth Tragedy: Policies and Ethnic Divisions

Explaining cross-country differences in growth rates requires not only an understanding of the link between growth and public policies, but also an understanding of why countries choose different public policies. This paper shows that ethnic diversity helps explain cross-country differences in public policies and other economic indicators. In the case of Sub-Saharan Africa, economic growth is associated with low schooling, political instability, underdeveloped financial systems, distorted foreign exchange markets, high government deficits, and insufficient infrastructure. Africas high ethnic fragmentation explains a significant part of most of these characteristics.

Stock Markets, Banks, and Economic Growth

Using data on 49 countries from 1976 to 1993, the authors investigate whether measures of stock market liquidity, size, volatility, and integration in world capital markets predict future rates of economic growth, capital accumulation, productivity improvements, and private savings. They find that stock market liquidity-as measured by stock trading relative to the size of the market and economy - is positively and significantly correlated with current and future rates of economic growth, capital accumulation, productivity growth, even after controlling for economic and political factors. Stock market size, volatility, and integration are not robustly linked with growth. Nor are financial indicators closely associated with private savings rates. Significantly, banking development -as measured by bank loans to private enterprises divided by GDP -when combined with stock market liquidity predicts future rates of growth, capital accumulation, and productivity growth when entered together in regressions. The authors determine that these results are consistent with views that (1)financial markets and institutions provide important services for long-run growth, and (2)stock markets and banks provide different financial services.

Financial Intermediation and Growth: Causality and Causes

The authors evaluate: a) whether the level of development of financial intermediaries exerts a casual influence on economic growth; and b) whether cross-country differences in legal and accounting systems (such as creditor rights, contract enforcement, and accounting standards) explain differences in the level of financial development. Using both traditional cross-section, instrumental-variable procedures and recent dynamic panel techniques, they find that development of financial intermediaries exerts a large causal impact on growth. The data also show that cross-country differences in legal and accounting systems help determine differences in financial development. Together, these findings suggest that legal and accounting reform that strengthens creditor rights, contract enforcement, and accounting practices boosts financial development and accelerates economic growth.

Finance, entrepreneurship and growth☆

Abstract How do financial systems affect economic growth? We construct an endogenous growth model in which financial systems evaluate prospective entrepreneurs, mobilize savings to finance the most promising productivity-enhancing activities, diversify the risks associated with these innovative activities and reveal the expected profits from engaging in innovation rather than the production of existing goods using existing methods. Better financial systems improve the probability of successful innovation and thereby accelerate economic growth. Similarly, financial sector distortions reduce the rate of economic growth by reducing the rate of innovation. A broad battery of evidence suggests that financial systems are important for productivity growth and economic development.

Finance and the Sources of Growth

The authors evaluate whether the level of development in the banking sector exerts a causal impact on economic growth and its sources-total factor productivity growth, physical capital accumulation, and private saving. They use (1) a pure cross-country instrumental variable estimator to extract the exogenous component of banking development and (2) a new panel technique that controls for country-specific effects and endogeneity. They find that: Banks do exert a large, causal impact on total factor productivity growth, which feeds through to overall GDP (Gross Domestic Product) growth. The long-run links between banking development and both capital growth and private savings are more tenuous.

A New Database on Financial Development and Structure

The authors introduce a new database of indicators of financial development and structure across countries and over time. This database is unique in that it unites a variety of indicators that measure the size, activity, and efficiency of financial intermediaries and markets. It improves on previous efforts by presenting data on the public share of commercial banks, by introducing indicators of the size and activity of non bank financial institutions, and by presenting measures of the size of bond and primary equity markets. The compiled data permit the construction of financial structure indicators to measure whether, for example, a countrys banks are larger, more active, and more efficient than its stock markets. These indicators can then be used to investigate the empirical link between the legal, regulatory, and policy environment and indicators of financial structure. They can also be used to analyze the implications of financial structure for economic growth. The authors describe the sources and construction of, and the intuition behind, different indicators and present descriptive statistics.

Bank Regulation and Supervision: What Works Best?

This paper uses our new database on bank regulation and supervision in 107 countries to assess the relationship between specific regulatory and supervisory practices and banking-sector development, efficiency, and fragility. The paper examines: (i) regulatory restrictions on bank activities and the mixing of banking and commerce; (ii) regulations on domestic and foreign bank entry; (iii) regulations on capital adequacy; (iv) deposit insurance system design features; (v) supervisory power, independence, and resources, (vi) loan classification stringency, provisioning standards, and diversification guidelines; (vii) regulations fostering information disclosure and private-sector monitoring of banks; and (viii) government ownership. The results, albeit tentative, raise a cautionary flag regarding government policies that rely excessively on direct government supervision and regulation of bank activities. The findings instead suggest that policies that rely on guidelines that (1) force accurate information disclosure, (2) empower private-sector corporate control of banks, and (3) foster incentives for private agents to exert corporate control work best to promote bank development, performance and stability.

Stock Markets, Banks, and Growth: Panel Evidence

This paper investigates the impact of stock markets and banks on economic growth using a panel data set for the period 1976-98 and applying recent GMM techniques developed for dynamic panels. On balance, we find that stock markets and banks positively influence economic growth and these findings are not due to potential biases induced by simultaneity, omitted variables or unobserved country-specific effects.
