Help with d and e parts

Consider the full version of the Solow model with both population growth and technology: Y; = F (Kg, LtEE). We will extend this version of Solow to also explicitly include the government. The national income accounts identity becomes: K=C+Ig+al where G: is government spending in period t. In order to fund its spending the government collects a tax Tc. Suppose for simplicity that the government runs a balanced budget G; = T; and that the tax collected is a constant fraction 0' of output: G; = T; = 0%. The remaining disposable income for households each period is (1 a)Yt. As in Solow we still assume that households save/invest a constant fraction .5 of their (now disposable) income. The population growth rate is n, techonology grows at g, and the depreciation rate is d. (a) Assume for now that there is only private and no public investment (i.e all government purchases are spent on consumer goods and none of G; is used to invest in capital). Write down the standard system the equations for output, consumption, investment, and the capital accumulation equation. Dene: ye: Ei'h,kt=,it=.ct=.gt=h. (b) Transform the model from. part (a) in per eective worker form and derive the steady~state equation for capital per effective worker. Draw a graph depicting the steady state. (c) What is the effect of higher tax rate or on the steady state? Show the eect on your graph and explain the intuition for your answer. (d) Now suppose that, in addition to the case in part (a), a. fraction d: of I} is also invested in the capital stock, i.e. public investment equals (9T; = aYt. What is total investment equal to now? Similarly to part (b) derive the steady-state equation for capital per worker and depict your answer on a graph. (e) Sh0w that if 95 is sufciently high (i.e. you will need to nd a specic threshold value), then the steady state capital per effective worker will increase as a result of higher taxation. Explain the intuition for your
