Depending on the size of the price increase, reduced consumption of tobacco products following increases in tobacco taxes can be quite substantial. In 1999, a World Bank review concluded that, all else being equal, price rises of about 10% would on average reduce tobacco consumption by about 4% in developed countries and about 8% in developing countries. In their 2003 meta-analysis reviewing 86 studies published to the year 2001 which examined the price elasticity of demand for tobacco products, Gallet and List found a mean price elasticity of –0.48, meaning that, on average, a 10% increase in price will be followed by a decrease in consumption of 4.8%.

Cross elasticity of demand - Wikipedia

In the chapter that introduced the model of demand and supply, we saw that an inferior good is one for which demand falls when income rises. It is likely to be a good that people do not really like very much. When incomes are low, people consume the inferior good because it is what they can afford. As their incomes rise and they can afford something they like better, they consume less of the inferior good. When the price of an inferior good falls, two things happen:

Income elasticity of demand - Wikipedia

Because each consumer’s response to a price change depends on the sizes of the substitution and income effects, these effects play a role in determining the price elasticity of demand. All other things unchanged, the larger the substitution effect, the greater the absolute value of the price elasticity of demand. When the income effect moves in the same direction as the substitution effect, a greater income effect contributes to a greater price elasticity of demand as well. There are, however, cases in which the substitution and income effects move in opposite directions. We shall explore these ideas in the next section.

When the elasticity is calculated over a certain arc or section of the demand curve, it is

Price Elasticity of Demand (PED) - Investing Answers

If the quantity demanded changes a when prices change a little, a product is said to be . This often is the case for products or services for which there are many alternatives, or for which consumers are relatively price sensitive. For example, if the price of Cola A doubles, the quantity demanded for Cola A fall when consumers switch to less-expensive Cola B.

Price Elasticity of Demand [Mackinac Center]

When there is a small change in demand when prices change a lot, the product is said to beinelastic. The most famous example of relatively demand is that for gasoline. As the price of gasoline increases, the quantity demanded doesn't decrease all that much. This is because there are very few good substitutes for gasoline and consumers are still willing to buy it even at relatively high prices.

IB Economics notes on 2.2 Cross price elasticity of demand (XED)

It is also a sensitivity of quantity towards changes of price and it is measured using the elasticity concept with a diagram of demand and supply curve.

Cross price elasticity of demand (XED) - IB guides

Price elasticity is usually negative, as shown in the above example. That means that it follows the law of demand; as price increases quantity demanded decreases. As gas price goes up, the quantity of gas demanded go down.

Price elasticity that is positive is uncommon. An example of a good with positive price elasticity is caviar. The buyers of caviar are generally individuals who believe that the more expensive the caviar, the better it must be. Thus, as the price of caviar goes up, the quantity of caviar demanded by wealthy people goes up as well.

Price elasticity of demand - Economics Online

There are mainly two types of elasticity, the elasticity of demand which includes price elasticity of demand, income elasticity of demand, and cross elasticity of demand as well as elasticity of supply (McConnell, Brue, & Flynn, 2009)ii.
