1. Demand (4 points) a. What is Willingness-to-Pay (WTP) and what are three(3) determinants of WTP? b. Consider a market that consists of 3 groups of individuals. The table below illustrates the marginal willingness to pay for each group of individuals:   Individual 1 Individual 2 Individual 3 WTP for first ton coal ($/ton) $60/ton $80/ ton $50/ ton WTP for second ton coal ($/ton) $52/ ton $70/ ton $35/ ton WTP for third ton coal ($/ton) $40/ ton $50/ ton $20/ ton WTP for fourth ton coal ($/ton) $20/ ton $35/ ton $18/ ton WTP for fifth ton coal ($/ton) $18/ ton $30/ ton $13/ ton WTP for sixth ton coal ($/ton) $16/ ton $20/ ton $9/ ton Using the table above, graph the market demand curve for coal at a market price of $20/ton, illustrating the quantity demanded.   c. Illustrate the change in demand if all individuals receive an increase in income. 2. Supply (3 points) a. What are two(2) determinants of supply? b. The table below gives the marginal costs for three(3) individual coal producers.   Individual 1 Individual 2 Individual 3 MC for first ton coal ($/ton) $18/ton $3/ton $1/ton MC for second ton coal ($/ton) $20/ton $5/ton $2/ton MC for third ton coal ($/ton) $24/ton $9/ton $4/ton MC for fourth ton coal ($/ton) $30/barrel $13/ton $7/ton MC for fifth ton coal ($/ton) $38/barrel $20/ton $12/ton MC for sixth ton coal ($/ton) $50/barrel $30/ton $20/barrel Using the table above, draw the market supply curve for the coal market given a market price of $20/ton, illustrating the quantity supplied.  b. Illustrate the change in supply for a policy implemented that requires increases the price of coal permits required for mining coal.   3. Coal Market (8 points) a. Using the information in questions (1) and (2), draw the market diagram for the coal market. b. Indicate the market equilibrium and the equilibrium condition. c.
