Investment in an uncertain world Part A. Part A (50 per cent of the marks) 1a. Consider a closed economy with households, firms and a government sector, where total current government expenditure is equal to total current revenue (from taxation). Table 1 reports data from the economy’s national accounts: (i) Calculate public expenditure as a percentage of GDP.?


10,000,000 = 6,000,000 + 1,000,000 + G G = 10,000,000 – 6,000,000 – 1,000,000 = G = 3,000,000 G as a percentage of GDP = (G divided by Y) and multiplied by 100. =(3,000,000/10,000,000) *100 = = 30 per cent. (ii) Calculate households’ savings as a percentage of GDP. Explain your calculations.
