Suppose the production function for widgets is given byq = kl - 0.8k2 - 0.2l2where q represents the annual quantity of widgets produced, k represents annual capital input, and l represents annual labor input.a. Suppose k = 10; graph the total and average productivity of labor curves. At what level of labor input does this average productivity reach a maximum? How many widgets are produced at that point?b. Again assuming that k = 10, graph the MPl curve. At what level of labor input does MPl = 0?c. Suppose capital inputs were increased to k = 20. How would your answers to parts (a) and (b) change?d. Does the widget production function exhibit constant, increasing, or decreasing returns to scale?
Indicate whether the following statement is TRUE or FALSE and explain your answer: ‘Consider threeinputs of production: labour, physical capital and natural resources, and an economy with decreasingreturns to scale. If you increase all three inputs x times then the total gross domestic product (GDP) inthe economy will increase exactly x times, but GDP per capita will decrease.’
Assume instead that pharmacists and robots dispense prescriptions according to the following production function: Y = 10*KO.8L0.2 where Y is the number of prescriptions dispensed; L is the number pharmacist hours, and K is the number of robot hours.

The economy of Ouratricot has 50 units of labor and 30 units of capital. Ouratricot has a production unit that produces knitted goods with a technology described by the production function QT=min{2KT,LT} where QT is the quantity of knitted goods produced, KT is the quantity of capital used in the knitted goods production unit, and LT is the quantity of labor used in the knitted goods production unit. Ouratricot has a production unit that produces Ouras with a technology described by the production functionQO=min{KO,LO} where QO is the quantity of Ouras produced, KO is the quantity of capital used in the production unit of Ouras, and LO is the quantity of labor used in the production unit of Ouras. Find all of the capital and wage allocations between the two production units that are likely to be part of an optimal allocation in the sense of Pareto in the economy of Ouratricot. Justify your answer with precision and clarity.
0.5 0.5 Given a production function: Y = AK N If output grows at 5%, capital grows at 2% and the number of workers grows at 4%, then technology (or total factor productivity) grows at % ? (Answer in integer only, no decimal place.) Your Answer: Answer Given a production function: Y = AK0.5 N0.5. If output grows at 5%, capital grows at 2% and the number of workers grows at 4%, then technology (or total factor productivity) grows at %? (Answer in integer only, no decimal place.) Your Answer: Answer
Consider the following graph of a production function when capital is constant. (The following is a description of the figure: it shows a two-axis graph; the horizontal axis measures labor and the vertical axis measures output; for a K fixed, the graph shows that maximal production that the firm can achieve with different levels of labor; the graph starts at cero production for zero labor; then it is increasing in all of its range; three levels of labor are shown as reference; there are L1, L2, and L3; they are related as follows L1<L2<L3; the graph is convex from 0 to L1, that is, its slope is increasing; the graph is concave from L1 on, that is, its slope is decreasing; the line that is tangent to the curve at L2, passes through the origin of the graph.) Denote by APL(L,K)=f(L,K)/L the so-called average product of labor (here f is the production function of the firm). From the graph we know that for the corresponding K: APL(L1,K)=MPL(L1,K) APL(L2,K)>MPL(L2,K)…
