The accumulation of the capital stock in the Solow model is given by: K. sY. In the Solow model, per-capita income depends on the capital stock. Solow sets up a mathematical model of long-run economic growth. He assumes full employment of capital and labor. For a difference in the stock of physical capital per man. 1. Output and capital per worker grow at the same constant, positive rate in BGP of model. In long run model reaches BGP.
