Suppose a country enacts a tax policy that discourages investment, and the policy reduces the investment rate immediately and permanently from  to ʹ. Assuming the economy starts in its initial steady state, use the Solow model to explain what happens to the economy over time and in the long run. Draw a graph showing how output evolves over time (put Yt on the vertical axis with a ratio scale and time on the horizontal axis), and explain what happens to economic growth over time.
