Production function estimation with micro-data shows that a persistent unobserved variable varies within firm or plant over time but resists treatment and may cause biases. This paper presents an estimation model of the firm under endogenous productivity change. The model implies that (i) the...

How strong are strategic complementarities in price setting across firms? In this paper, we provide a direct empirical estimate of firms' price responses to changes in prices of their competitors. We develop a general framework and an empirical identification strategy to estimate the...
