42. DEMAND AND SUPPLY Factors that affect both demand and supply

43. Demand The total amount of commodity that all households wish to purchase in some time period is called the quantity demanded of the commodity.

44. What determines Quantity demanded? Commodity’s own price Average household income Prices of related commodities Tastes Distribution of income among households Size of population Commodity’s own price Average household income Prices of related commodities Tastes Distribution of income among households Size of population

45. Demand and price A basic economic hypothesis is that the lower the price of a commodity, the larger the quantities that will be demanded other things being equal.

46. Supply The amount of a commodity that firms wish to sell in some period is called the quantity supplied. The amount of a commodity that firms wish to sell in some period is called the quantity supplied.

47. What determines Quantity Supplied Commodity’s own price Price of inputs Goals of firms State of technology Commodity’s own price Price of inputs Goals of firms State of technology

48. What is Macroeconomics As it is study of how the economy behaves in broad outline without dwelling on much of its interesting.the price levels, employment, total output and the interest rate are key macroeconomic variables for the domestic side of economy.

49. DEMAND INCOME The higher the income the greater the quantity of goods demanded The lower the income the greater the quantity of goods demanded The graph shows a decrease in income. INCOME The higher the income the greater the quantity of goods demanded The lower the income the greater the quantity of goods demanded The graph shows a decrease in income.

50. POPULATION This affects the number and type of buyers. The size, age of the population etc all affect demand. E.g a rise in the birth rate will increase the demand for baby products The graph shows a rise in population. This affects the number and type of buyers. The size, age of the population etc all affect demand. E.g a rise in the birth rate will increase the demand for baby products The graph shows a rise in population.

51. TASTES Each consumer has a particular set of preferences. These change over time and businesses need to continue to provide appropriate products. The graph shows the change in demand over the years for flared trousers. Each consumer has a particular set of preferences. These change over time and businesses need to continue to provide appropriate products. The graph shows the change in demand over the years for flared trousers.

52. ADVERTISING A business will need to be aware of the tactics of its competitors so as to respond. If businesses advertise their business then it stands to reason that demand for a good or service will increase. A business will need to be aware of the tactics of its competitors so as to respond. If businesses advertise their business then it stands to reason that demand for a good or service will increase.

53. SUBSTITUTES If the price of a similar good falls then the demand for the original good is likely to decrease because more people will buy the substitute good. E.g The price of crunchy nut cornflakes fall so the demand for rice crispies fall. If the price of a similar good falls then the demand for the original good is likely to decrease because more people will buy the substitute good. E.g The price of crunchy nut cornflakes fall so the demand for rice crispies fall.

54. SUPPLY COSTS These costs may include the costs for raw materials, labour, expenses etc. Obviously if costs are reduced then the company will be able to supply more and vice versa The graph shows a decrease in costs. COSTS These costs may include the costs for raw materials, labour, expenses etc. Obviously if costs are reduced then the company will be able to supply more and vice versa The graph shows a decrease in costs.

55. CHANGES IN TECHNOLOGY New production methods using computer-controlled systems and new materials can reduce production costs. This means a company can supply more of a good. New production methods using computer-controlled systems and new materials can reduce production costs. This means a company can supply more of a good.

56. PHYSICAL CONDITIONS World events often affect the supply of resources. This may include war in other countries or physical conditions such as an earthquake or disease. These factors will all limit supply. World events often affect the supply of resources. This may include war in other countries or physical conditions such as an earthquake or disease. These factors will all limit supply.

57. SUBSIDIES The government use subsidies to protect industries. Here producers do not bear all the costs, goods become cheaper to produce and they are supplied to the market at a lower price This has the affect of increasing supply.
