This paper evaluates the empirical relation between the level of financial
intermediary development and (i) economic growth, (ii) total Factor product
ivity growth, (iii) physical capital accumulation, and (iv) private savings
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 with simultan
eity and unobserved country-specific effects. After controlling for these p
otential biases, we End that(1) financial intermediaries exert a large, pos
itive impact on total factor productivity growth, which feeds through to ov
erall GDP growth and (2) the long-run links between financial intermediary
development and both physical capital growth and private savings rates are
tenuous. (C) 2000 Elsevier Science S.A. All rights reserved. JEL classifica
