### “If markets are competitive, the rate of return on capital equals its marginal product, $f'(k)$ minus depreciation $\delta$”?

Consider Solow model with $Y=(AL)^{1-a}K^a$. Then output per effective labor is $y=k^a$ where $k=\frac{K}{AL}$. "If markets are competitive, the rate of return on capital equals its marginal product,...
