Holiday Home Work - Economics

11 AS

Section A

Venezuela is suffering the worst economic crisis in its history. Ordinary people in this oil-rich country

are regularly going without food. Angry, hungry mobs are queuing outside almost empty

supermarkets. The government has declared a state of emergency, food is being transported under

armed guard, and basic necessities are being rationed. People have to queue for hours and

sometimes overnight to receive basic commodities, such as rice and cooking oil.

Venezuela has the largest known oil reserves in the world — even greater than Saudi Arabia. In the

past the government used money from oil exports to fund its own expenditure and to support

domestic consumption. In addition, more than 1200 private companies in a wide range of sectors,

such as sugar plantations and dairy farms, were nationalised. But in 2015 the oil price fell by 50%

and this resulted in a shortage of money to fund government spending. The government maintained

their spending by printing money, fuelling inflation.

As Venezuela’s currency, the bolivar, was losing value, those holding bolivars increasingly exchanged

them for US dollars. As a result, a restriction was placed upon those who could legally buy US dollars

and the exchange rate was fixed. Unable to buy US dollars legally, businesses turned to the black

market, where the value of the US dollar soared. While the official exchange rate is 10 bolivars per

US dollar, the bolivar now trades on the black market at more than 1000 bolivars per US dollar. The

collapse of the currency is made worse by oil’s continuing low price — Venezuela can no longer rely

on its oil exports bringing back enough US dollars, which means it can’t import enough goods,

leading to shortages.

The government tried to ration basic foodstuffs and fix their prices, but as a result it became

unprofitable for Venezuelan companies to make such things, and as a consequence they have simply

disappeared from the shops into other illegal markets.

Source: The Guardian, 22 June 2016

(a) Use a production possibility curve diagram to show what is expected to happen to the

Venezuelan economy between 2014 and 2017. [2]

(b) Explain what the change in the price of oil in 2015 and the resulting fall in Venezuela’s

earnings from oil exports suggest about the price elasticity of demand for Venezuelan oil. [2]

(c) Explain why price controls have resulted in shortages of basic foodstuffs in the shops in

Venezuela. Use a demand and supply diagram to support your answer. [4]

Section B

2. (a) Explain why both merit goods and demerit goods are examples of private goods. [8]

(b) Discuss whether merit goods and demerit goods are best provided by a market

economy. [12]

3. (a) Explain the factors that can affect the price elasticity of demand for a product. [8]

(b) Discuss the extent to which knowledge of a product’s cross-elasticity of demand is

likely to be important to a firm supplying that product. [12]

4. (a) Explain the way in which economists measure how much the supply of a good changes

as its price changes. Explain two factors that influence the result. [8]

(b) Discuss whether decision-making is more effective when undertaken by governments

in a planned economy rather than by individuals in a free market economy. [12]
