This paper examines whether nancial development facilitates economic growth by scrutinizing one rationale for such a relationship; that nancial development reduces the costs of external nance to rms. Speci cally, we ask whether industrial sectors that are relatively more in need of external nance develop disproportionately faster in countries with more developed nancial markets. We nd this to be true in a large sample of countries over the 1980s. We show this result is unlikely to be driven by omitted variables, outliers, or reverse causality. (JEL O4, F3, G1) A large literature, dating at least as far back as Joseph A. Schumpeter (1911), emphasizes the positive in uence of the development of a country's nancial sector on the level and the rate of growth of its per capita income. The argument essentially is that the services the nancial sector provides { of reallocating capital to the highest value use without substantial risk of loss through moral hazard, adverse selection, or transactions costs { are an essential catalyst of economic growth. Empirical work seems consistent with this argument. For example, on the

This paper evaluates (1) whether the exogenous component of financial intermediary development influences economic growth and (2) whether cross-country differences in legal and accounting systems (e.g., 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, we find that the exogenous components of financial intermediary development is positively associated with economic growth. Also, the data show that cross-country differences in legal and accounting systems help account for differences in financial development. Together, these findings suggest that legal and accounting reforms that strengthen creditor rights, contract enforcement, and accounting practices can boost financial development and accelerate economic growth.

Abstract: This paper evaluates the empirical relationship between the level of financial intermediary development and (i) economic growth, (ii) total factor productivity growth, (iii) physical capital accumulation, and (iv) private saving rates. We use (a) a pure cross-country instrumental variable estimator to extract the exogenous component of financial intermediary development, and (b) a new panel technique that controls for biases associated to simultaneity and unobserved country-specific effects. After controlling for these potential biases, we find that (1) financial intermediaries exert a large, positive impact on total factor productivity growth, which feeds through to overall GDP growth; and (2) the long-run links between financial intermediary development and both physical capital growth and private saving rates are tenuous.

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

The manufacturing sectors of less developed countries (LDCs) have traditionally been relatively protected. They have also been subject to heavy regulation, much of which is biased in favor of large enterprises. Accordingly, it is often argued that manufacturers in these countries perform poorly in several respects: (1) markets tolerate inefficient firms, so cross-firm productivity dispersion is high; (2) small groups of entrenched oligopolists exploit monopoly power in product markets; and (3) many small firms are unable or unwilling to grow, so important scale economies go unexploited. In this paper I assess each of these conjectures, drawing on plant and firm-level studies of LDC manufacturers. I find none to be systematically supported. Turnover is substantial, unexploited scale economies are modest, and convincing demonstrations of monopoly rents are generally lacking. Nonetheless I find some evidence that protection increases firms ’ price-cost margins and reduces average efficiency levels at the margin. Finally, although the econometric evidence on technology diffusion in LDCs is limited, it does suggest that protecting “learning ” industries is unlikely to foster productivity growth. All of this suggests that the general trend toward trade liberalization has yielded larger benefits that the traditional gains from trade.

This paper examines the relationship between the legal system and banking development and traces this connection through to long-run rates of per capita GDP growth, capital stock growth, and productivity growth. The data indicate that countries where the legal system (1) emphasizes creditor rights and (2) rigorously enforces contracts have better developed banks than countries where laws do not give a high priority to creditors and where enforcement is lax. Furthermore, the exogenous component of banking development -- the component defined by the legal environment -- is positively and robustly associated with per capita growth, physical capital accumulation, and productivity growth.

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.
