Ques 1
The government is planning to build a bridge which connnects the North and South of the country. The cost of building the bridge is $2,000,000. The marginal cost of building the bridge is zero. The government must decide if it will build the bridge or contract the sole construction company in the country to build the bridge. If the company builds the bridge, it will recover its costs and possibly earn a profit from charging residents to use the bridge. The demand schedule is shown in the table below:
