The demand curve shows the amount of goods consumers are willing to buy at each market price. A linear demand curve can be plotted using the following equation. Qd = a – b(P) Q = quantity demand a = all factors affecting QD other than price (e.g. income, fashion) b = slope of the demand …
Since the 1980s, UK train travel has increased sharply. Despite above-inflation price increases, demand for travel by train continues to grow. This is due to several factors including – economic growth, congestion on roads, higher rents in city centres, causing more demand for commuting. Three interesting graphs from Social Trends vol 40.

Definition of composite demand Demand for a good that has multiple different uses. e.g. People may demand oil because it can be used to create either petrol or plastics. Examples of composite demand People may demand wheat for producing bread, biofuels or feeding livestock. Land can be used for farming or building houses. Steel could …
When calculating elasticity of demand there are two possible ways. Point elasticity of demand takes the elasticity of demand at a particular point on a curve (or between two points) Arc elasticity measures elasticity at the midpoint between the two selected points:
Cross elasticity of demand (XED) measures the percentage change in quantity demand for a good after a change in the price of another. For example: if there is an increase in the price of tea by 10%. and the quantity demanded for coffee increases by 2%, then the cross elasticity of demand = 2/10 = …
Demand deficient unemployment occurs when there is insufficient demand in the economy to maintain full employment. In a recession (a period of negative economic growth) consumers will be buying fewer goods and services. Selling fewer goods, firms sell less and so reduce production. If firms are producing less, this leads to lower demand for workers …
Demand for labour is a derived demand. This means it depends on demand for the product the worker is producing. If there is an increase in demand for visiting coffee shops, it will lead to an increase in demand for baristas (people who make coffee) The demand for labour will also depend on labour productivity, …
Derived demand occurs when there is a demand for a good or factor of production resulting from demand for an intermediate good or service. Example – mobile phones and lithium batteries The rise in demand for mobile phones and other mobile devices has led to a strong rise in demand for lithium. Lithium is used in …
