1. Output and capital per worker grow at the same constant, positive rate in BGP of model. In long run model reaches BGP.In this video I introduce the Solow growth model and show how to solve for the steady state. The steady state is the key to understanding the solo model. At the steady state investment is equal to depreciation. The solo model begins with a production function which is simply a mathematical model describing how output is produced. Solow sets up a mathematical model of long-run economic growth. He assumes full employment of capital and labor. Assume capital is the same as the final good of the economy, but used in the production process of more goods. Wealth stock measures the financial value of the capital stock, rather than its productive capacity.
