3Labor Demand and Supply
The labor supply curve of Plain City is steeper than the labor supply curve of Island City.
The reasons behind this mismatch between the slopes of the supply curves of these two cities are
the difference in cost of living and lack of resources (Seeley, 2017). Plain city is featureless and
thus it has less resources than Island City. Therefore, cost of living is higher in the Plain City as
it has to build all means of living and also depend on imports unlike Island City (Neuman et al.,
2015). Therefore, wage of labor will be higher and with rise in employment the cost of
expanding Plain City is more and thus labor supply curve is steeper in the case of Plain City.
Answer 3
Equilibrium employment and equilibrium wage in Growville are 100, 000 and $100
respectively. Additionally, the wage elasticity of demand is -1 and wage elasticity of supply is
5.0. Therefore, with increase in labor demand by 18% the equilibrium wage of labor increases by
Percenatge increase∈wage= Percentage increase∈labor demand
∑ of wage elasticity of demand∧wage elasticity of supply
¿ , Percenatge increase∈ wage= 18
(1+5)
¿ , Percenatge increase∈wage=3 %
Therefore, after 18% increase in demand equilibrium wage increases to $103.
Similarly, with increase in equilibrium price and demand by 3% and 18% respectively, the
percentage increase in equilibrium wage is given by
Percentage increase ∈equilibrium employment =Increase∈equilibrium price × Wage elasticity of supply
¿ , Percentage increase∈ equilibrium employment = ( 3× 5 ) %

4Labor Demand and Supply
¿ , Percentage increase∈equilibrium employment =15 %
Therefore, after 18% increase in labor demand the equilibrium employment increases to 115,
000.
From the above calculations it is found that wage and employment has both increased in
Growville. Therefore, with increase in income there will be more demand for houses and thus
there will be rise in demand in the real estate market (Carvalho & Rezai, 2015). Subsequently,
the real estate market would expand and there will be more revenue and thereby profit in the
market.

pollution. It means the firms in cities U and T generate 50 tons of pollution each. City T
implements a tax policy to reduce the pollution and owing to that the firms in the city has to
reduce their production. Consequently, the pollution of City T reduced by 20% to 80 tons (Hanna
& Oliva, 2015). However, the equilibrium employment reduced by (LT-LT1) as shown in diagram
3. Similarly, City U also implemented the same policy to reduce pollution. It is observed that in
City U that each of the two firms reduced pollution by 20% that means each now produces 40
tons of pollution. It implies that City U produces 80 tons of pollution in total which is similar as
City T. Thus, it can be inferred that equilibrium employment in City U has reduced by the
amount equal to (LT-LT1).
