GROWTH MODEL WITH FINANCIAL DEEPENING AND PRODUCTIVITY HETEROGENEITY

摘要

This paper studies the effects of financial deepening on growth dynamics and productivity in an economy where heterogeneous entrepreneurs face endogenous borrowing constraints. Quantitative results from a calibrated model suggest that 38% of Japan's total factor productivity from 1961 to 1991 can be explained by the financial deepening effects and the convergence speed is 29% slower than that implied by neoclassical models. The present paper also theoretically shows that an economy with a higher degree of productivity heterogeneity is more likely to avoid the poverty trap and converge with a slower speed to its steady state.
