Abstract

Using a dataset of Japanese multinational firms that contains firm-level sales forecasts, we provide new evidence on imperfect information and learning over the firm's life cycle. We find that firms make non-negligible and positively correlated forecast errors over time. However, they make more precise forecasts and less correlated forecast errors, as they become more experienced. We then build a model with heterogeneous firms that gradually learn about their demand. We quantify the learning and real options channels along the age dimension, through which greater micro-level uncertainty adversely affects resource allocation at the extensive margin and thus depresses productivity.
