This paper models learning by experience beyond the experience curve, including the possibility of
‘‘learning to learn’’: the pace of learning increases over time by building on what has already been learned. We compare the extended deterministic learning model with Jovanovic and Nyarkos’ [26] stochastic learning. The theoretical models are tested with data on the total factor productivity of a car-assembly plant in its first months of operation. We find that the deterministic ‘‘mixed learning model’’, where the speed of learning is equal to a constant plus a learning to learn effect, is the one that best fits the empirical data. The mixed learning model results in a time pattern of total factor productivity growth, first increasing and later decreasing, different from the always decreasing rate of growth of the learning curve, opening new perspectives on the study of learning by experience.

1. Introduction
Productivity, or the rate at which input quantities are turned into outputs, has received much attention at the macro (as determinant of differences in the per capita income of countries
[43]), at the firm (as explanatory of differences in competitiveness and
