Answer: The equilibrium price of a magazine decreases and equilibrium quantity remains the same.
Step-by-step explanation:
The magazine and newspaper are substitute goods. So, if the price of a newspaper decreases as a result the demand for magazine decreases.
This shifts the demand curve of magazine leftwards from DD to D'D' in the diagram.
And, if the wage rate paid to the magazine production workers decreases as a result the cost of magazine production decreases.
This will increase the supply of magazine and shift the supply curve towards right from SS to S'S' in the diagram.
Hence, the equilibrium price of a magazine decreases from P to P' and equilibrium quantity remains the same at Q0 = Q1.
