I need help with questions 1-4 inclusively, if anyone can help with any of the above I would really appreciate it

1. Discuss how housing, both new construction and rents (included imputed ones), are treated in the three approaches to GDP. 2. If GDP does not account for improvements in quality, then the GDP deflator tends to understate the true rate of inflation. True/false and explain. 3. The real interest rate can never be negative since you can always keep your wealth in the form of money which pays a nominal interest rate of zero. True/false and explain. 4. Suppose the government deficit is 5, tax revenues are 15, consumption expenditures are 60, the current account surplus is 10 and national saving (private plus public) is 20. Calculate GDP. What is the private saving rate in this economy? What is the investment rate in this economy? Explain why these rates can be different. 5. Convergence in the Solow model. The following figure, reproduced from the lecture notes, plots the average yearly growth rates for OECD countries against their initial level of income in 1960. . a) Is the Solow model consistent with the negative relationship between initial income level and subsequent growth? Explain your answer. b) Over the same period, Africa as a whole grew at an average rate of 2% per year. A growth rate similar to that of the US although capital per worker in the US is 80 times higher than in an average African country. Is this evidence against the Solow model? Explain your answer. 6. Assume that the Solow model provides an accurate representation of the two Germanies around the late 80s and early 90s. Although in 1989 both countries re-unified, for this problem we will treat them as two separate economies and we will model the effects of the reunification as
