12. What happens with no diminishing returns? Consider a Solow model where the production function no longer exhibits diminishing returns to capital accu- mulation. This is not particularly realistic, for reasons discussed in Chapter 4. But it is interesting to consider this case nonetheless because of what it tells us about the workings of the Solow model. Assume the production function is now Y, = AK. The rest of the model is unchanged. (a) Draw the Solow diagram in this...

Consider the Solow growth model with the following production function where y is output. K is capital, s is the productivity and is labor. Assume that 0 < α < 1 Further, suppose that labor grows at a constant rate n. That is. 1 + n. Also, assume that capital depreciates at rate d and that gross investment in capital is fraction s of output. a Letting k-N, obtain the law of motion for capital accumulation...
2. Consider the Solow growth model. Suppose that the production function is constant returns to scale and it is explicitly given by: Y = K L l-a a. What is the level of output per capita, y, where y = Y/L? b. Individuals in this economy save s fraction of their income. If there is population growth, denoted by n, and capital depreciates at the rate of d over time, write down an equation for the evolution of capital per...
Consider the Solow growth model. The production function is given by Y = K αN1−α , with α = 1/3. Depreciation rate δ = 0.05, and saving rate s = 0.25. Labor force grows at the rate n = 0.01. (a) Write down the law of motion for capital per worker. (b) Compute steady state capital per worker. (c) Suppose the economy has initial capital per worker k0 = 4. Describe the dynamics of this economy, i.e., how does capital...
Consider a version of the Solow model where the population growth rate is 0.05. There is no technological progress. Capital depreciates at rate ? each period and a fraction ? of income is invested in physical capital every period. Assume that the production function is given by: ?t = ?t1/2 ?t1/2 where ?t is output, ?t is capital and ?t is labour. a. Derive an expression for the accumulation of capital per worker in this economy, i.e. ∆?t+1 where ?t...
Consider the Solow growth model without labor force or technology growth. Suppose y = k^1/4, total factor productivity is constant and equal to 1, s = 0.40, and d = 0.05. Find the steady-state capital––labor ratio for this economy. Find the steady-state real GDP per worker for this economy. Find the steady-state level of investment per worker for this economy. Find the steady-state level of consumption per worker for this economy.
2. Consider a Solow growth model with Cobb-Douglas production function Y Ko (AN)-a with constant savings rate s, depreciation rate d and no growth in productivity or labor (gA = gN = 0) (a) Suppose A = 1, a = 1/3, s = 0.2 and 5 = 0.1 (annual). Calculate the steady state capital per worker and steady state output per worker (b) Suppose that the real wage w and real return to capital r are equal to the marginal...
Consider the Solow growth model. Output at time t is given by the production function Yt = AKt3 L3 , where A is total factor productivity, Kt is total capital at time t and L is the labour force. Total factor productivity A and labour force L are constant over time. There is no government or foreign trade and Yt = Ct + It where Ct is consumption and It is investment at time t. Every agent saves s share...
Given the Solow model, a production function y = Ak1/3; depreciation =δ , and an investment rate=γ. (a) Draw the basic Solow model from class, labeling all lines, axes, and the steady state. (b) Start a new diagram. Assume a country in its steady state is hit by an earthquake that destroys physical capital but does not kill anyone. Draw a Solow model that describes the transition of the country from (1) its original steady state to (2) its immediate...
