1. Illustrate and explain the individual labour supply curve. 2. The Government of Ghana's tight regulations on working conditions of coal mining have resulted in decrease in the danger of mining. Use graph to analyse what would likely happen to employment and wages in the coal mining industry in Ghana. 3. The supply curve for private schoolteachers in Eastern bloc is given as Ls =-20 + 3w, and the corresponding demand curve is L,=40-2w, where L is the number of schoolteachers in thousands and w is the hourly wage in cedis. Determine the equilibrium wage and employment levels in this market. 4. One major cause of juvenile delinquency in Ghana is the high rate of unemployment among SHS graduates.
