Questions

  1. Identify the factors on the demand and supply sides that have led to the rise in tea prices. Draw a diagram to illustrate your answer.

  3. If the price of tea in the shops rises, will this necessarily mean a rise in the price to tea growers and in the wages of workers on tea plantations? Explain using concepts of competition and market power.
  4. What will be the effect of using more land for growing tea on (a) the price of tea and (b) the incomes of tea growers?

  5. If the price of crude oil goes up by x per cent, is the price of petrol at the pump likely to go up by x per cent or by more or less than x per cent? Explain your answer.

According to both the Lloyds Banking Group’s Halifax price index and the Nationwide Building Society, the annual rate of decline in house prices is reducing and the three-monthly figures now show a small increase in house prices. So does this mean that the housing market is now recovering?

The Centre for Economics and Business Research (CEBR) is forecasting a rise of 2 per cent in house prices between the end of 2009 and the end of 2010. Other forecasters are predicting higher price increases. Part of the reason lies on the demand side, but part also lies on the supply side. The following linked articles explore these determinants of demand and supply.
