So it is not safe to assume that a price increase is always the way to greater revenues. Elasticity of demand equal to one, or in other words; unit elasticity of demand, therefore, represents the dividing line between elastic and inelastic demand. Smoked salmon is seen as a treat to most people, a luxury rather than a necessity. Demand responses to a change in the price of chocolate should be completed within a few months, but the full adjustment to changes in the price of oil or cigarettes may take years.

Indeed, if prices are above £6 per unit in our example, total revenue can only be increased by cutting prices. Elasticity of Demand on a Linear Demand Curve 4. The accuracy of the percentage method is questioned on the ground that the value of the elasticity depends on which value is taken as the starting point in the calculation of percentage.

So, when the price of petrol rises, I am likely to buy more or less the same amount of petrol, unless I make a concerted effort to use public transport unlikely, especially if one lived in the countryside or give up the car even more unlikely! The three demand schedules in the table below show how many rounds of golf per year Lorena will demand at each price under three different scenarios. The same proposition also applies to supply. Since our formula is equal to the inverse of our slope multiplied by a point on the graph, it will only equal 1 when our point is equal to the slope of our graph. Elasticity of Demand and Supply 9. The proportionate change in demand is smaller than the proportionate change in price. This is significant because the newspaper supplier can calculate or estimate how revenue will be affected by the change in price.
