Document Summary
Ch 7 economic growth i: capital accumulation and population. Differences in income come from differences in capital, labor and technology. Solow growth model: theory of economic growth in per-capita income: shows how saving, population growth, and technological progress affect the level of an economy"s output and its growth over time. Supply & demand for goods determine the accumulation of capital: assumptions: labor force & technology is fixed. Supply of goods is based on the production function : y = f(k,l) Since the solow model assumes constant returns to scale: y/l = f(k/l, l/l, therefore, y = f(k) Shows that the amount of output per worker (y/l) is a function of the amount of capital per worker (k/l) Slope of the production function shows how much extra output a worker produces when given an extra unit of capital: mpk = f(k+1) f(k)
