Note on Uzawa's Two-Sector Model of Economic Growth

This Note has two objectives: one expository and one analytical. I am afraid that many readers will be put off by the apparent mathematical difficulty of Uzawa’s paper. I say “ apparent ” advisedly, because the paper is in part very easy; it requires only a little arithmetic and the bare elements of the calculus of functions of one variable. Any economist who cannot read it ought at least to insist that his students do so. My first objective is to describe in plain English how the model works, because I think it is an interesting extension of earlier work in this branch of macro-economics.
