D) it is constant.

46) Suppose that two countries share identical levels of total factor productivity, identical labor force growth rates and identical savings rates. According to the Solow model

D) the country with the smaller initial level of output per worker will grow more rapidly than the country with the greater initial level of output per worker.

4) In an exogenous growth model, growth is caused by

C) forces that are not explained by the model itself.

37) With the Golden Rule,

D) savings maximize consumption.

10) All of the following increase total factor productivity except

D) more capital.

A) 2%.

33) In Solow's exogenous growth model, the steady-state growth rate of capital can be increased by

A) higher population growth.

28) In the steady state of Solow's exogenous growth model, an increase in the savings rate

A) increases output per worker and increases capital per worker.

40) In the steady state of Solow's exogenous growth model, an increase in total factor productivity

35) The Golden Rule of capital accumulation maximizes the steady-state level of

B) consumption per worker.

17) The biggest contribution to real GDP growth in the "East Asian Tigers" during the period 1966-1991 was due to growth in

39) In the steady state of Solow's exogenous growth model, an increase in the growth rate of labor force

C) decreases output per worker and decreases capital per worker.

20) The slope of the output per worker function is equal to the

C) marginal product of capital.

45) In the Solow growth model, countries with identical total factor productivities, identical labor force growth rates, and identical savings rates

D) in equilibrium, have identical levels of capital per worker and output per worker.

36) In the Golden Rule steady state, the marginal product of capital is equal to the

D) procyclical and have about equal magnitude as percentage deviations from trend in GDP.

22) In Solow's model of economic growth, suppose that s represents the savings rate, z represents total factor productivity, k represents the level of capital per worker, and f(k) represents the per-worker production function. Also suppose that n represents the population growth rate and d represents the depreciation rate of capital. The equilibrium level of capital per worker, k, will satisfy the equation

D) szf(k*) = (n + d)k*.

24) In Solow's exogenous growth model, the principal obstacle to continuous growth in output per capita is due to

D) the declining marginal product of capital.
