Learning by doing, organizational forgetting, and the business cycle

Abstract

AbstractThis paper supplements a learning‐by‐doing real business cycle model with endogenous organizational forgetting. Empirical evidence shows that the accumulated experience decay rate is not constant over the business cycle, but that forgetting is a function of economic activity. Learning reinforces the effects of productivity shocks, and organizational forgetting exacerbates their impact and increases their persistence. This is of particular interest when a negative productivity shock hits the economy, as the increasing speed of forgetting aggravates the negative shock and delays recovery.
