A shift in demand means at the same price, consumers wish to buy more. A movement along the demand curve occurs following a change in price. Movement along the demand curve A change in price causes a movement along the demand curve. It can either be contraction (less demand) or expansion/extension. (more demand) Contraction in …
Price elasticity of demand measures the responsiveness of demand to a change in price. Price inelastic – a change in price causes a smaller % change in demand. Price elastic – a change in price causes a bigger % change in demand. Price inelastic demand We say a good is price inelastic, when an increase …
A kinked demand curve occurs when the demand curve is not a straight line but has a different elasticity for higher and lower prices. One example of a kinked demand curve is the model for an oligopoly. This model of oligopoly suggests that prices are rigid and that firms will face different effects for both …
A look at the different factors affecting the price of oil in both short term and long. Readers Question: I’m trying to update myself on what’s happening with oil prices at the moment (partly to prepare myself for uni interviews) but I’m finding very conflicting articles, such as: Article warning of oil rising to $150 …
In a recent post, we looked at food inflation and noted how prices were often volatile. Primary products like food and oil tend to be volatile because: Supply is inelastic in short run. (Supply is unresponsive to temporary shortages of food) Supply can vary due to the weather/geopolitical events. Demand is price inelastic – a …
Changes in price cause signals in the market mechanism. For example, if there is an increase in demand this will lead to a higher price and a movement along the supply curve. However, in the long run, high prices act as an incentive for firms to supply more. Therefore firms will expand their production or …
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:
Earlier in the year, Sony reduced the price of its PlayStation VR bundle from $499 to $449, a significant 10% reduction in price. Given there is significant brand loyalty towards PlayStation (and inelastic demand), what are the possible economic reasons behind cutting the price? Complementary products One very strong reason is to make profit from …
