Consider three imaginary countries. In Aire, saving amounts to $4,000 and consumption amounts to $12,000; in Bovina, saving amounts to $3,000 and consumption amounts to $24,000; and in Cartar, saving amounts to $10,000 and consumption amounts to $50,000. The saving rate is

higher in Aire than in Cartar, and it is higher in Cartar than in Bovina.

Which of the following is a determinant of productivity?

human capital per worker, physical capital per worker, natural resources per worker

Productivity is the

key determinant of living standards, and growth in productivity is the key determinant of growth in living standards.

lower this year than last year. A possible source of this change in productivity is a change in the size of the capital stock.

Country A has twice as many workers as Country B. Country A also has twice as much physical capital, twice as much human capital, and access to twice as many natural resources as Country B. Assuming constant-returns to scale, which of the following is higher in Country A?

neither productivity nor output per worker

In the equation for the production function Y/L represents
