The loan productivity shock is treated as the supply side financial disturbance. Together with NT’s net worth shock that resembles the credit demand perturbation, both of the two-sided shocks are robustly extracted by combining the model with US quarterly data. The two shocks are found to be tightly linked with the post-war recessions. Each recession happens when both of the two shocks become contractionary. A few potential economic downturns seem to have been avoided because of the expansion of credit which offset the simultaneous contraction of entrepreneurial net wealth.
