Question 1: Market for lobster (20 points) The annual demand and supply for Atlantic lobster is given by the following equations:
100 0.2 DP Q= − , and 25 0.1 SP Q= + , where P is the price per Kg in dollars, QD and QS are respectively the quantity demanded and the quantity supplied (in thousand of Kgs).
1. Construct the Demand and Supply curves to scale. Show all the work, and intercepts and make sure that all axis and curves are labelled properly (10 points).
2. Let P* and Q* be the equilibrium price and quantity for lobster. Explain the concept of the equilibrium price and quantity. Calculate P* and Q* and show them in the graph. Provide all theoretical justifications for your calculations (10 points).
Question 2: Market for Handmade Acoustic Guitars (30 points) After several years of decline the market for handmade acoustic guitars is making a comeback. These guitars are usually made in small workshops employing relatively few highly skilled workers. Using the Supply and Demand model fully explain the changes in the market in each of the following cases. Illustrate your answers with simple graphs by indicating the demand and/or supply changes and the resulting equilibrium price and quantity and their direction of change (show whether the price and quantity in the new equilibrium has increased or decreased).
1. Music using handmade acoustic guitar makes a comeback as audiences tire of heavy metal and grunge music.
2. A foreign producer reengineers the guitar making process and floods the market with guitars
3. Canada goes in deep recession in which the income of the average Canadians falls sharply
4. Environmentalists succeed in having the use of Brazilian rosewood banned in Canada, forcing producers to seek out alternative, more costly woods
Question 3: Market for Chocolate (25 marks) An article in the New York Times stated:
While the world’s appetite for chocolate grows more voracious each year, cocoa farmers around the globe are failing, under siege from fungal and viral disease and insects….. Researchers predict a shortfall in beans from the cocoa tree, the raw material from which the chocolate is made, in as little as five to ten years.
1. Describe in terms of supply and demand mechanism what is described in the
quote. 2. What is the implied prediction for the equilibrium price of chocolate?

3. What is the implied prediction for the equilibrium quantity of chocolate, considering that the effect on supply is much more significant than the effect on demand?
Fully explain your answers and illustrate them with a simple graph of S and D. .Question 5: Market for Illegal Drugs (25 points) Few years ago the Canadian government proposed a new legislation on drug control. According to the proposal, much harsher penalties would be imposed on marijuana production, while the possession of small amounts of the drug would no longer constitute a criminal offence. It was understood that the more severe penalties would have a stronger effect than the decriminalization of the possession of small amounts.
a. Show the effects of such legislation on the market for marijuana by fully explaining the shifts in Demand and Supply curves if this legislation came into force;
b. Show the resulting new equilibrium price and quantity and fully explain their direction of change.
c. Illustrate your answers graphically in a simple D&S model. Hint: Consider a simultaneous shift on both the demand and supply curves.
