Financial frictions and the persistence of history

"We quantify the role of financial frictions and the initial misallocation of resources in explaining development dynamics. Following a reform that triggers efficient reallocation of resources, our model economy with financial frictions converges slowly to the new steady state-it takes twice as long to cover half the distance to the steady state as the neoclassical growth model. Investment rates and total factor productivity start out low and rise over time. These model dynamics are endogenously determined by the extent of initial resource misallocation and the degree of financial frictions. We present data from post-war miracle economies on the evolution of macro aggregates, factor reallocation, and establishment size distribution, which support the aggregate and micro-level implications of our theory"--National Bureau of Economic Research web site.
