Problem Set 5 - Externalities and Efficiency - Assignment subjectUse a supply and demand diagram to illustrate your answer and provide no to a greater extent than five sentences of explanation.When prices are set below the equilibrium, i.e P2, there will be an increased demand in the houses by the population. Since supply remains constant as demand rises, there will be a briefage in the short run. However, in the long run, people will tend to build their protest houses or property owners will develop more to avoid the shortages. This increases the supply of the houses and reducing shortages.(Figure Market for Vaccines) The move into represents the market for vaccines with external benefits. The efficient level of takings is __1,800______ vaccines, which is ___greater_____ than the markets output.5. Suppose Tesco (A) and Sainsburys (B) both emit pollutants when producing their fictile bags used by customers to collect and carry their groceries home. The government enforces regul ations saying that neither firm can clit more than 10 units of pollutants. (Assume that pollutants can be measured in discrete and comparable units.) Currently Tesco releases 10 units and Sainsburys releases 11 units. The government requires Sainsburys to reduce its pollution by 1 unit the confederation can do this, but at a cost of 1,000. Tesco, however, can reduce its pollution by 1 unit for a cost of 400. Sainsburys wants to save money by trading allowances with Tesco. afterwards negotiations, Tesco agrees to see one unit of pollutant to Sainsburys for 650.From the diagram, P1 and Q1 are the equilibrium price and quantity respectively. In the short run the time is too short for firms to adjust production. However, in the long run, firms will increase output to Q2 and charge high price P2 due to an increase in shock demand. This leads to demand curve to stir from D1 to D2. This will make the firms to make abnormal profits. Since there is free entry, the excess profits will c url more firms into the market.
