There are two neighboring countries, Rich and Poor. The diagram above represents the annual labor market for each. K stands for thousands and M for millions. All supply and demand curves are straight lines. Initially, migration between Rich and Poor is not allowed. a. What is the equilibrium annual wage and level of employment in Rich? In Poor?
