Suppose that a Labour Market determines the Quantity of Labour (L) as functions of the wage
rate (w), according to the following Supply and Demand functions:
Supply: L = w
Demand: L=210 - 2w
9. [2 points] What is the free-market wage rate (w*) and Labour quantity (L*)?
Now suppose that the Labour Force forms a union, and collectively bargains to a price floor of
W = $80.
10. [3 points] What would be the Labour Decline and the Unemployment caused by this union
policy?
11. [2 points] Who wins and who loses from this union policy?
Suppose now that this union finds a way to push out the Demand for Labour to reduce this
Labour Decline.
12. [3 points] How much does the union need to increase the Demand function by in order
to reduce this Labour Decline to zero?

This monopolist also faces the demand: Q = 28-p 5. [3 points] If this monopolist is a single-price monopolist, then what price would it charge and what Quantity would it produce? What would be the Consumer Surplus (CS), Producer Surplus (PS), and Total Surplus (TS) in the single-price case? Now suppose that this firm can first-degree price discriminate. 6. [2 points] What would be the Consumer Surplus (CS), Producer Surplus (PS), and Total Surplus (TS) in the case where this monopolist can first-degree price discriminate? Now suppose that this firm cannot first-degree price discriminate, but can instead second-degree price discriminate. Now suppose that this monopolist offers the menu of: 12 units for p = $16 • 18 units for p = $10 7. [2 points] Will the above make consumers better off? Will it make firms better off?

Profit maximization Consider Blewitt's Farm, a small blueberry grower relative to the size of the market whose production has no impact on wages and prices. The following table presents Blewitt's production schedule for blueberries: Labor Output (Number of workers) (Pounds of blueberries) 0 0 1 18 2 34 3 48 4 60 5 70 Suppose that the market wage for blueberry pickers is $170 per worker per day, and the price of blueberries is $12 per pound. On the following graph, use the blue points (circle symbol) to plot Blewitt's labor demand curve when the output price is $12 per pound. Note: Remember to plot each point between the two integers. For example, when the number of workers increases from 0 to 1, the value of the marginal product of for the first worker should be plotted with a horizontal coordinate of 0.5, the value halfway between 0 and 1. Line segments will automatically connect the points.
