If the daily demand curve for gasoline is as provided in the following graph, then how much consumer surplus would consumers receive if the market price for gasoline was $1.60 per litre? What about for a price of $1.20 per litre?

Suppose the Canadian demand for and the Japanese supply of cars to Canada is shown in the table below (quantities in thousands). Quantity Supplied (before tariff) Quantity supplied (after tariff) Price ($) 13,000 14,000 15,000 16,000 17,000 18,000 19,000 20,000 Quantity Demanded 170 150 130 110 90 70 50 30 50 70 90 110 130 150 170 190 a) The present equilibrium price is $ and quantity is b) Suppose that the Canadian government imposes a $2,000 per car tariff on imported Japanese cars. Show the new supply in the last column above. thousand. thousand. c) The new equilibrium price is $ and quantity is d) The total revenue received by the government will be $ e) Assume, instead, that the government imposes an import quota of 90,000 cars. The new equilibrium price is $ quantity is thousand. f) Does the government now receive any revenue? No million. and

Consider a hypothetical market for copper (q), where q is measured in 1000 tons. Suppose the supply of virgin copper is Sv = 10+5q. Suppose that the supply for recycled copper is Sr = 15+2.5q. Demand for copper is P = 65 - 1.5q. Note, buyers don't distinguish between recycled and virgin copper. The equilibrium price and output for copper is (hint: draw a graph) q=8.46, p = $52.31. q=0, p = $65. q=12.50, p = $46.25. O q=4.44, p = $58.33.

In the market for hand sanitizers the demand function is given by: q = 80 - p, where q is the quantity of hand sanitizers (in thousands) and p is the price of hand sanitizers in dollars. Suppose the current market price for hand sanitizers is $4. 1. What is the inverse demand function equal to? Draw it in a diagram. 2. At a price of $4, what is the level of consumer surplus? 3. Due to the unprecedented COVID-19 pandemic, people's preferences for sanitizing their hands change in favor of hand sanitizers. In fact, for any given price of hand sanitizers, people now want to purchase 20 units (in thousands) more hand sanitizers. o What is the new demand curve? o What is the new inverse demand curve? o Draw the new inverse demand curve in your diagram. 4. Suppose that after the increase in demand, the new price becomes $8. What is consumer surplus equal to at this new price (and with the new inverse demand curve)? 5. [Challenge Question] What would the consumer surplus be if the government…
