Using the per-worker production function graph from Figures 22.3 and 22.4 on pages 738 and 740, show the effect on real GDP per hour worked of an increase in capital per hour worked, holding technology constant. Now, again using the per-worker production function graph, show the effect on real GDP per hour worked of an increase in technology, holding constant the quantity of capital per hour worked.
