) In a closed-market economy with unionized labor, suppose unions suddenly get a significant negotiation power on labor contracts at time t and thereby enforced a real wage rate that is 10 percent higher than the market-clearing real wage rate.

Explain in detail by showing the changes in the relevant markets.
