uestion 3 In 2,010, the average price of a certain industrial material was SR 16.08 per liter. Suppose the base year is 2,005 and the price of such material during that year was SR 11.4 per liter. What is the average inflation rate between the given periods? Write your answer in decimal format and round-off only the final answer in four dec Formulas: log() log1+0 d, - 4,0+* -a

Each term (3 months) the current group of economics students completed a questionnaire as to how much they would spend on new purchases compared to how much they would save/pay off bills, if they suddenly and unexpectedly received a check for $1,000. The average MPC is shown in the table below. Month in which student poll was taken Average of students’ responses as MPC March 0.41 June 0.30 September 0.22 December 0.56   What do these MPC’s imply about the students’ thinking over the course of the year?   (Enter response here.)   What is likely happening in the economy during the same period of time?

13. (Use this information to answer qustion 13 - 16) Suppose a household solves the following two-period consumption-savings problem max u(c₁) + Bu(c2) {C1,C2} s.t. aw Y1 - C1 C2y2 (1+r)a with u(c) = √c where c₁ is consumption at time 1, c2 is consumption at time 2, y₁ is houshold income at time 1, 2 is houshold income at time 2 and w is the initial wealth. Suppose the incomes of the household are $50 in time 1 and $210 in time 2. The initial wealth is $100, the discount factor is 0.975 and interest rate is 5%. Solve for the household's choice of C1. (a) 125.12 (b) 126.58 (c) 175.16 (d) 341.88 14. Now a government wants to introduce income tax in both time 1 and time 2 {1, 2} to finance a construction project that costs $50 in time 1 and another $52.5 in time 2. Which ones of the following are the household intertemporal budget constraints. (a) y1 + 1/2 =C1+ 1+1 Y2 (b) w+y1 + = C₁ + 1+r 1+r (c) wy1T1 + Y2 T2 1+r Y2 1+r = €1 + 12 1+r (d) wy171 + =C1+ 1+r C2 (1+72) 1+r 15. Solve for the…

3. [Sometimes, it's useful to think about what fraction of a consumer's money they spend on each good, rather on how many units they buy. (a) Show that every x EX(p,m) can be written as x = f1(m/p₁,0) + f2(0, m/p2 ) + (1-f1-f2)(0,0) for some numbers f1,f2 20 with f1 + f2 ≤1. (b) Let f1 and f2 be as in part (a). Give an expression, in terms of f1 and f2, for the fraction pix₁/m of the consumer's money that they spend on good 1. (c) Let f1 and f2 be as in part (a). Give an expression, in terms of f1 and f2, for the fraction p2x2/m of the consumer's money that they spend on good 2
