1、Name: _ Date: _1.The Solow growth model describes:A)how output is determined at a point in time.B)how output is determined with fixed amounts of capital and labor.C)how saving, population growth, and technological change affect output over time.D)the static allocation, production, and distribution o
2、f the economys output.2.Unlike the long-run classical model in Chapter 3, the Solow growth model:A)assumes that the factors of production and technology are the sources of the economys output.B)describes changes in the economy over time.C)is static.D)assumes that the supply of goods determines how m
3、uch output is produced.3.In the Solow growth model, the assumption of constant returns to scale means that:A)all economies have the same amount of capital per worker.B)the steady-state level of output is constant regardless of the number of workers.C)the saving rate equals the constant rate of depre
4、ciation.D)the number of workers in an economy does not affect the relationship between output per worker and capital per worker.4.The production function y = f(k) means:A)labor is not a factor of production.B)output per worker is a function of labor productivity.C)output per worker is a function of
5、capital per worker.D)the production function exhibits increasing returns to scale.5.When f(k) is drawn on a graph with increases in k noted along the horizontal axis, the:A)graph is a straight line.B)slope of the line eventually gets flatter and flatter.C)slope of the line eventually becomes negativ
6、e.D)slope of the line eventually becomes steeper and steeper.6.When f(k) is drawn on a graph with increases in k noted along the horizontal axis, the slope of the line denotes:A)output per worker.B)output per unit of capital.C)the marginal product of labor.D)the marginal product of capital.7.Two eco
7、nomies are identical except that the level of capital per worker is higher in Highland than in Lowland. The production functions in both economies exhibit diminishing marginal product of capital. An extra unit of capital per worker increases output per worker:A)more in Highland.B)more in Lowland.C)b
8、y the same amount in Highland and Lowland.D)in Highland, but not in Lowland.8.The consumption function in the Solow model assumes that society saves a:A)constant proportion of income.B)smaller proportion of income as it becomes richer.C)larger proportion of income as it becomes richer.D)larger propo
