Macro Eco
Question 1:
Assume that Econoland produces haircuts and shirts with inputs of labor. Econoland has 1000 hours of labor available. A haircut requires ½ hour of labor, while a shirt requires 5 hours of labor. Construct Econolands PPF.
Answer 1:
To construct Econolands Production Possibility Frontier (PPF) we first need to understand what is a PPF.
A production possibilities frontier (PPF) is a graph showing the different quantities of two goods that an economy can efficiently produce with limited productive resources.
Points along the curve describe the trade-off between the two goods, that is, the opportunity cost. Opportunity cost here measures how much an additional unit of one good costs in units forgone of the other good. The curve illustrates that increasing production of one good reduces maximum production of the other good as resources are transferred away from the other good.
Given:
Econoland produces two goods
o Shirts
o Haircuts.
1000 hours of labor is the constraint
Haircut requires 0.5 hours of labour
Shirt requires 5 hours of labour
HS = Line indicating the PPF (which in this case is a straight line)
With the given constraint of 1000 hours of labour we get the cases where:
o Pt H indicates the situation when all labour units are being employed to produce 2000 haircuts ( As haircut requires 0.5 hrs => 2000*0.5 = 1000 labor hours)
o Pt S indicates the situation where all labour units are being employed to produce 200 shirts ( As shirt requires 5 hrs => 200*5 = 1000 labor hours)
The slope of the production possibilities frontier (PPF) at any given point is called the marginal rate of transformation (MRT) or the marginal rate of technical substitution (MRTS). It describes numerically the rate at which one good can be transformed into the other. It is also...
