Over the past 100 years or so, the development experience of many countries
is described by two facts: (1) The economy’s capital/labor ratio rises, and (2) The share
of labor and capital in national income are roughly constant. How can this be? What do
these two empirical facts suggest about the form of the production function? (Hints: (1) The
share of labor is w · L/Y and the share of capital is R · K/Y , (2) Assume factor markets are
competitive, so factors are paid their marginal products).
