Problem 3

According to leading coffee merchants, there will be a shortage in the global coffee market due to Brazil's declining coffee production in 2014-2015. ${ }^{\omega 2}$ Brazil is the world's largest producer of coffee beans.
a. Using demand and supply analysis, illustrate the effect of Brazil's declining coffee production on the global coffee market in 2014. Show the shortage of coffee beans in your graph.
b. With the shortage, how would you expect the price of coffee beans to change in 2014 ?
c. Arabica coffee beans were being traded at seven-year lows in November 2013. If the demand for coffee beans decreases further in 2014 , along with the change mentioned above, how would you expect the equilibrium price and quantity of Arabica coffee beans to change? Draw a graph to explain your answer.

Problem 4

Consider the following discussion. ${ }^{63}$
It has been a tough year in the poultry business, with supply outpacing demand and feed-grain prices rising substantially. But producers are hoping all that changes when the summer cook-out season starts.
The seasonal upswing in chicken consumption, along with the anticipated jump in spot-market poultry prices, could bring some relief to producers whose profit margins have been slashed by surging corn and soybean-meal costs.
Rising feed-grain prices, accelerated by the diversion of corn to make ethanol, have pushed up the cost of producing a live chicken by as much as 65 percent over the past two years.
Three factors make analysts more optimistic:
Companies are cutting production, weekly egg-set numbers are declining (egg sets are fertile eggs placed in incubators), and prices are responding positively to the decreasing supply.
The production slowdown is a response to the surge in feed-grain prices last fall.
Profit margins at producers will not improve unless spot-market prices for chicken move up fast enough to cover costs paid for corn and soybean meal to feed chicken flocks. Production cutbacks and seasonal demand have helped fuel a 20 -cent increase in boncless, skinless breast-meat prices to $$\$ 1.46$$ a pound. Prices are expected to reach at least $$\$ 1.80$$ by summer 2008 .
a. Use demand and supply analysis to illustrate the changes in chicken prices described in the above article.
b. Describe what has happened in the corn and soybean-meal markets and how that has influenced the chicken market.

Problem 5

In early 2014, China decided to cancel the 1.2 million ton rice import contract with Thailand. ${ }^{64}$ Using demand and supply analysis, answer the following questions with supporting graphs.
a. What will be the effect of the cancellation of the import contract on the equilibrium price and quantity of rice in Thailand? b. What will be the effect of the cancellation of the import contract on the equilibrium price and quantity of rice in China?
c. If China increases the import of rice from Vietnam in order to stabilize the domestic price of rice, how will it affect the equilibrium price and quantity of rice in Vietnam?
d. Suppose the Vietnamese rice producers have built the storehouses and expect the increasing demand for rice from China will keep pushing the price up in the future. How would you expect the current equilibrium price and quantity of rice in Vietnam to change, compared to those before China increases the import of rice from Vietnam?
