2. Suppose we have the following data to study if a country's per capita income (measured in thousands of dollars) is a function of its R&D spending (measured as a percentage of GDP). ( country 1 2 3 4 xi yi 1 4 2 6 3 7 4 10 (1) Calculate beta hats with OLS. (2) Calculate R2 and adjusted R².
5. Using the accelerator model in which the level of inventories in current period depends on the expected sales following this equation: Nt= a ESt Where N stands for the current level of inventories, ESt stands for the level of expected sales and alpha is a parameter equal to 0.6. The growth or increase in inventories is given by AN, = B(N₁-N₁-1), where Beta parameter is equal to 0.3 a) Suppose that the initial level of inventories is zero and the forecasting for sales for this period is equal to 200. Can you quantify the level of inventory investment? What would it be total production in period 1? b) Now suppose that in the second period there growth of inventories is 12%. What is the value of inventory investment for period 2 and forecasting sales for period 2?
Graph and label as either direct or indirect the relationships you would expect to find between (a) the number of inches of rainfal per month and the sale of umbrellas, (b) the amount of tuition and the level of enrollment at a university, and (c) the popularity of an entertainer and the price of her concert tickets.

2. Question 2: Suppose that you estimate a model of the aggregate annual retail sales of new cars that specifies that sales of new cars are a function of real disposable income, the average retail price of a car adjusted by the consumer price index, and the number of sports utility vehicles sold (you decide to add this independent variable to take account of the fact that some potential new car buyers purchase sports utility vehicles instead). You use the data (annual from 2000 to 2014) and obtain the following estimated regression equation: CARS, = 1.32 + 4.91Y D; + 0.0012 PRICE, - 7.14 SUV (2.39) (0.00045) (71.40) 1 where CARS = new car sales (in hundreds of thousands of units) in year t, YD; = real disposable income (in hundreds of billions of dollars), PRICE = the average real price of a new car in yeart (in dollars), SUV = the number of sports utility vehicles sold in year t (in millions). You expect the variable YD to have a positive coefficient and the variables PRICE and SUV to…
(1)The following macroeconomic model describes the economy of Sunderland. 1. Y= C +I + G + NX 2. C = 220 + 0.63 Y 3. 1 = 1000- 2000R 4. G = Go 5. NX = 525-0.10Y-50OR 6. M (0.1583Y-1000R)P (a)ls it a fair characterization to refer to equation #2 as a "simple" consumption function? Explain. (b)Derive the expression for equilibrium real output, Y, for this economy. Note: In your final expression for Y, restrict coefficient values to three decimal points.
