We propose an alternative formu- lation of the augmented Olley-Pakes decomposition that includes entry and exit, and applies to both levels of productivity and the percentage change. The key idea is to recognize that productivity is fundamentally a residual, which allows us to measure the Olley-

We show that an index restriction plays a crucial role in the identification, especially if the capital stock is measured by the perpetual inventory method.
Webinvestment decisions made by the farm in the past. The decision to adopt improved genetics is an investment into future productivity based on current conditions including productivity of the exis-ting cohort. Much like the framework of Olley and Pakes (1996), dairy farms make investments every year in the genetics of their herd. Web2.1 Olley and Pakes OP addres the endogeneity problem as follows. First, they assume that cap-ital is a fixed input subject to an investment process.
