This paper reviews, appraises, and critiques theoretical and empirical research on the connections between the operation of the financial system and economic growth. While subject to ample qualifications and countervailing views, the preponderance of evidence suggests that both financial intermediaries and markets matter for growth and that reverse causality alone is not driving this relationship. Furthermore, theory and evidence imply that better developed financial systems ease external financing constraints facing firms, which illuminates one mechanism through which financial development influences economic growth. The paper highlights many areas needing additional research.

Abstract: We document five stylized facts of economic growth. (1) The "residual" rather than factor accumulation accounts for most of the income and growth differences across nations. (2) Income diverges over the long run. (3) Factor accumulation is persistent while growth is not persistent and the growth path of countries exhibits remarkable variation across countries. (4) Economic activity is highly concentrated, with all factors of production flowing to the richest areas. (5) National policies closely associated with long-run economic growth rates. We argue that these facts do not support models with diminishing returns, constant returns to scale, some fixed factor of production, and that highlight the role of factor accumulation. Empirical work, however, does not yet decisively distinguish among the different theoretical conceptions of "total factor productivity growth." Economists should devote more effort towards modeling and quantifying total factor productivity.

A New Database on Financial Development and Structure iii Summary This paper introduces a new database of indicators of financial development and structure across countries and over time. This database is unique in that it unites a wide 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 nonbank financial institutions and by presenting measures of the size of bond and primary equity markets. This paper describes the sources, the construction and the intuition for the different indicators and presents descriptive statistics. A New Database on Financial Development and Structure v

We show that equity market liberalizations, on average, lead to a one percent increase in annual real economic growth over a five-year period. The effect is robust to alternative definitions of liberalization and does not reflect a business cycle effect. The channel of growth is both increased investment post liberalization which partially reflects a decreased cost of capital and increased factor productivity. The additional investment is largely financed by foreign capital leading to deteriorating trade balances. Some of the liberalization effect can be accounted for by coincidental macroeconomic reforms as well as financial development. However, our analysis shows that even after controlling for a broad range of variables, a statistically significant and economically important role is played by equity market liberalization. We appreciate the helpful comments of Wayne Ferson, Peter Henry, Ross Levine, Graciela Kaminsky,

Average incomes of the poorest fifth of society rise proportionately with average incomes. This is a consequence of the strong empirical regularity that the share of income accruing to the bottom quintile does not vary systematically with average income. In this paper we document this empirical regularity in a large sample of 92 countries spanning the past four decades, and show that it holds across regions, time periods, income levels, and growth rates. We next ask whether the factors that explain cross-country differences in growth rates of average incomes have differential effects on the poorest fifth of society. We find that several determinants of growth -- such as good rule of law, openness to international trade, and developed financial markets -- have little systematic effect on the share of income that accrues to the bottom quintile. Consequently these factors benefit the poorest fifth of society as much as everyone else. There is some weak evidence that stabilization from high inflation as well as reductions in the overall size of government not only raise growth but also increase the income share of the poorest fifth in society. Finally we examine several factors commonly thought to disproportionately benefit the poorest in society, but find little evidence of their effects. The absence of robust findings emphasizes that we know relatively little about the broad forces that account for the cross-country and intertemporal variation in the share of income accruing to the poorest fifth of society. _________________________ 1818 H Street N.W., Washington, DC, 20433 (ddollar@worldbank.org, akraay@worldbank.org).

For over a century, economists and policy makers have debated the relative merits of bank-based versus market-based financial systems. Recently, however, proponents of the legal-based view of financial development have argued that the century long debate concerning bank-based versus market-based financial systems is analytically vacuous. According to this view, the critical issue is establishing a legal environment in which both banks and markets can operate effectively. This paper represents the first broad, cross-country examination of which view of financial structure and economic growth is most consistent with the data.

Abstract: This paper uses new statistical techniques and two new databases to reassess the relationship between economic growth and FDI. After resolving biases plaguing past work, we find that the exogenous component of FDI does not exert a robust, independent influence on growth.

Are market-based or bank-based financial systems better at financing the expansion of industries that depend heavily on external finance, facilitating the formation of new establishments, and improving the efficiency of capital allocation across industries? We find evidence for neither the market-based nor the bank-based hypothesis. While legal system efficiency and overall financial development boost industry growth, new establishment formation, and efficient capital allocation, having a bank-based or market-based system per se does not seem to matter much.

The Difference and System generalized method of moments (GMM) estimators are growing in popularity, thanks in part to specialized software. But as implemented in these packages, the estimators easily generate results by default that are at once invalid yet appear valid in specification tests. The culprit is their tendency to generate instruments that are a) numerous and, in System GMM, b) suspect. A large collection of instruments, even if individually valid, can be collectively invalid in finite samples because they overfit endogenous variables. They also weaken the Hansen test of overidentifying restrictions, which is commonly relied upon to check instrument validity. This paper reviews the evidence on the effects of instrument proliferation, and describes and simulates simple ways to control it. It illustrates the dangers by replicating two early applications to economic
