What is the principle of transition dynamics? Why does the Solow model leadto this principle, and why is it useful?
Why is the Malthusian model no longer regarded as an explanation for
modern economies? What are the main differences between the Malthusian and the Solow models?
Consider the basic Solow model with no population growth and no technological progress and a production function of the form F (K, H ), where H denotes the efficiency units of labor (human capital) given by where N is the set of all individuals in the population, and hi is the human capital of individual i. Assume that H is fixed. Suppose there are no human capital externalities and factor markets are competitive. (a) Calculate the steady-state equilibrium of this economy. (b) Prove that if 10% higher h at the individual level is associated with a% higher earnings, then a 10% increase in the country’s stock of human capital H will lead to a% increase in steadystate output. Compare this result to the immediate impact of an unanticipated 10% increase in H (i.e., consider the impact of a 10% increase in H with the stock of capital unchanged).

- Why is Solow Model important for any Economy?arrow_forwardConsider the Solow Model. Suppose a country enacts a tax policy that discourages investment, and the policy reduces the investment rate immediately and permanently from sbar to sbarprime . Assuming the economy (and hence the initial capital stock) is ABOVE its initial steady state (note: this is different from the standard case where we start at the intial steady state), use the Solow diagram to explain what happens to the economy over time and in the long run. Draw a graph showing how output evolves over time (put Y_t on the vertical axis with a ratio scale and time on the horizontal axis), and explain what happens to economic growth over time.arrow_forwardConsider the Solow model. Draw the paths over time for the log of y, c and k for an economy that starts below its balanced-growth path.arrow_forward
- Consider two countries in a Solow economy with growth in population but no growth in technological change. Assume both start from below their steady-state k∗, but one starts further below than the other, and all parameters are identical. On the same diagram, plot transition paths for each country.arrow_forwardWhat determines whether a curve shifts in the Solow diagram? Make a listof the parameters of the Solow model, and state whether a change in eachparameter shifts a curve (which one?) or is simply a movement along bothcurves.arrow_forwardIn the Solow model, population growth leads to steadystate growth in total output, but not in output per worker. Do you think this would still be true if the production function exhibited increasin g or decreasing returns to scale? Explain.arrow_forward
- Technical Progress in the Solow Model Suppose an economy that follows the assumptions of the Solow model saves a proportion s of its income every period, population grows at rate n, capital depreciates at rate d, and technical progress takes place at rate g. Assume it is not yet at steady state. a) Draw a graph to show initial level of capital k* < kss, output y* as well as the steady state levels of each. Be sure to draw and label the production function, investment and the line of effective depreciation, as well as k*, y*, kss and yss b) Explain what will happen to y* in the short run given this information (i.e. starting where k* < kss), according to the assumptions of the Solow growth model). c)At steady state, what is the growth rate of y*, y and Y?
