Solow sets up a mathematical model of long-run economic growth. He assumes full employment of capital and labor.Output and capital per worker grow at the same constant, positive rate in BGP of model. In long run model reaches BGP. 2. Write consumption per worker as a function of the capital stock in steady-state. We will examine how the model works when growth comes through capital accumulation, and how it works when growth is due to innovation. The Solow Growth Model is an exogenous model of economic growth that analyzes changes in the level of output in an economy over time.

The change in capital stock in the solow model is given by: a.
