Question 1:

 A group of rogue French farmers has gone on a furious egg breaking rampage, destroying tens of thousands on roads and pledging to smash many more in protest against low egg prices.

"More than 100,000 eggs were destroyed in the Cotes d'Armor (a division of Northwest Brittany) a spokesman for the unnamed collective of angry poultry farmers told AFP.

Poultry farmers in France have for months complained of rock-bottom egg prices due to overproduction - a problem that also affects other countries in the European Union.They say that current prices do not compensate for a rise in production costs or investments that they made as part of an EU directive of January 2012 to protect the well-being of laying hens.Their spokesman said that masked farmers had broken the 100,000 eggs overnight from Tuesday to Wednesday near Lidl supermarket and on a roundabout as reported in local media. 

"We will continue to destroy 100,000 eggs a day until Sunday and become more radical with inevitable collateral damage if the group's demands are not met" said their spokesman".  He also said that destroying 100,000 eggs a day equated to "five per cent of the production" of poultry farmer members of the collective.

The group called for France's entire production to be reduced by five per cent to help raise prices, and asked the government to set up a specific area for eggs to be destroyed.  According to Yves-Marie Beaudet of the egg section of the union that represents poultry farmers in Brittany, producers currently get paid 75 cents ($1.12 AUD) for a kilogram of eggs whereas the cost price is 95 cents.  The UGPVB union says that the EU has "15 to 20 million" excess laying hens out of a total of approximately 350 million.

(a) Explain and illustrate with a suitable diagram the cause(s) of low egg prices in France. 

(b) Explain and illustrate with a suitable diagram how the egg breaking rampage affects egg prices?

(c) Explain and illustrate with a suitable diagram the impact on egg prices if demand fell by 5% 

d) Would you consider the demand for eggs to be elastic or inelastic?  Explain your reason. 

(e) Illustrate and explain with a diagram how can the Government intervene and correct this situation? 

Question:

(a) Explain the concept of a concentration ratio.  Is the concentration ratio in a monopolistically competitive industry likely to be higher than for a perfectly competitive industry? 

b) Suppose the minimum point on the Long-run Average Cost (LRAC) curve of a soft drink firm's lemonade is $1 per litre.  Under conditions of monopolistic competition, will the price of a litre bottle of lemonade in the long-run be above $1, equal to $1, less than $1 or impossible to determine.  Illustrate your answer using a diagram (2 marks for diagram plus 2 marks for explanation)

Question:

What will happen to the equilibrium price and quantity of butter in each of the following cases?  Illustrate with a diagram and explain whether demand or supply (or both) have shifted and in which direction.  (In each case, assume ceteris paribus).

(b) A rise in the demand for yoghurt;

(c) A rise in the price of bread;

(d) A rise in the demand for bread;

(e) An expected rise in the price of butter in the near future;

(f) A tax on butter production;

(g) The invention of new, but expensive, process for removing all cholesterol from butter, plus the passing of a law which states that all butter producers must use this process.

Question:

(a) Suppose the income elasticity of demand for pre-recorded music compact disks is +4 and the income elasticity of demand for a cabinet maker's work is +0.4.  Compare the impact on pre-recorded music compact disks and the cabinet maker's work of a recession that reduces consumer incomes by 10 per cent. (b) How might you determine whether the pre-recorded music compact discs and MP3 music players are in competition with each other?

(c) Interpret the following Income Elasticities of Demand (YED) values for the following and stateif the good is normal or inferior;

YED= +0.5 and YED= -2.5

XED= + 0.64 and XED= -2.6
