Please help me out with those questions

1. Perpetual Inventory Method Calculate the capital productivity of China using information from the national income accounts. Use data from the United Nations Main Aggregate Database Link . Get data on GDP by Expenditure, at constant 2015 prices - National currency for China, People's Republic of, from 1970 to 2019. a. Guess the capital level in 1970. A reasonable first guess is that the investment in 1970 was just enough to replace depreciation 17 = 6 . K, Ko =[/, / 8]. Assume a constant depreciation rate, 6 =.05, and /, is constant dollar Gross Fixed Capital Formation. b. Use the equation K,4, = (1-8) . K, + 1,, to calculate the level of capital from 1971 to 2019. c. Use constant price GDP for output, Y,, and calculate the productivity of capital, APK, , in all periods from 1980 to 2019. In which period, was China's capital productivity the highest? d. Check to see if the initial guess matters. Guess the capital in 1970 was 5 times as large as your initial guess. K, =5x[17 / 8]. Use the alternative guess, to calculate estimates for capital through 2019. How large is the difference between capital productivity using your answer to Q1c. and your calculation using the different capital stock. e. Go back and get data for the Republic of Korea and do a similar exercise which you will use in the next session assuming K,, = [/7. / 8]. f. Use this data to calculate the ratio of investment to output for China, s, = [1, / Y, ]. Calculate the average investment rate, s, for the period 2010-2019.2. Productivity. A useful database for examining international productivity and growth issues are the Penn-World Tables hosted now at the University of Groningnen. M- Both the People's Republic of China and Korea have had extraordinary growth performance. Many analysts examine the trajectory of Korea to examine the likely trajectory. Go to Thematic gelggt to get data to calculate average labor productivity for Korea and China. This can be calculated using M series from Real GDP, Employment and Population Levels. Download series 1} Expenditure-side real GDP at chained PPPs {in mil. 2017055]; 2] Number of persons engaged (in millions); and 3) Average annual hours worked by persons engaged. Hours 3. Calculate the number of total hours as L: L, = x Workers. Workers, b. Calculate Labor productivity per hour for both China and Korea from 1980-2019. Korea's productivity level was somewhat similar to China's productivity in 2017 was 1990. We can think of Korea in this year, T: 1990, as a useful point of comparison for current day China in terms of the income per capita.

Use your measures of labor productivity, capital productivity, and human capital for Korea in 2000 to calculate the level of technology of Korea in 2000, 142%\".
