## Understanding Cross Elasticity of Demand Therefore concentration on price elasticity of demand is very important in designing advertising programs. Thus, bumper crop instead of raising their incomes reduces them. A grasp of demand elasticity guides firms toward more optimal competitive behavior and allows them to make precise forecasts of their production needs. They must be aware that demand falls with rise in price. In this formula, the price elasticity of demand will always be a negative number because of the inverse relationship between price and quantity demanded. Likewise, if the objective of devaluation is to reduce the imports of a country, then this will be realized only when the demand for the imports is elastic. If the cross elasticity of demand equals a negative number, this means the two products measured are complementary.

## Price Elasticity of Demand Applications Elasticity can be quantified as the ratio of the in one variable to the percentage change in another variable, when the latter variable has a causal influence on the former. The elasticity of demand also determines to what extent a tax on commodity can be shifted to the consumer. In other words, if the in a specific product causes a decrease in the quantity demand for another product, the two goods are connected in a complementary relationship. During depression period, demand for such goods decrease rapidly and sellers are adversely affected. At present its total earning is Rs. Demand for things like non-staple food - like cookies - is elastic.

## Understanding Cross Elasticity of Demand Assuming that there are no costs in producing the product, businesses would simply increase the price of a product until demand falls. Useful for forecasting demand: The concept of income elasticity of demand can be used for forecasting demand for a product over a period. Impact on Business Management Problems Price elasticity of demand affects a business's ability to increase the price of a product. When under perfect competition no signal firm exercises any control over the price of the product, it implies that the firm encounters perfect elastic demand curve. Wage Bargaining: The capacity of trade unions to raise wages depends on the elasticity of demand for the product in which labour is used as a major input.

## Demand Elasticity/Elasticity of Demand Since the result is less than 1, it is inelastic; the change in price has little effect on the quantity demanded. A simple ex­ample may make the point clear. If demand is price inelastic, then a higher tax will lead to higher prices for consumers e. Uses of Income Elasticity of Demand 1. This creates a problem in the area of law enforcement. This fact is elaborated below with the help of some leading areas in which elasticity of demand is used. Instead, they could try advertising to increase brand loyalty and make demand more inelastic 3.

## 12 Importance of Price Elasticity of Demand The symbol Q 1 represents the new quantity demanded that exists when the price changes to P 1. The price elasticity of demand as well as cross elasticity would determine the substitution between goods and hence useful in fixing the output mix in a production period. The fall in the income or revenue of the farmers as a result of this bumper crop is due to the fact that with greater supply the prices of the crops decline drastically and in the context of inelastic demand for them, the total expenditure on the crop output declines, bringing about fall in the incomes of the farmers. A variable can have different values of its elasticity at different starting points: for example, the quantity of a good supplied by producers might be elastic at low prices but inelastic at higher prices, so that a rise from an initially low price might bring on a more-than-proportionate increase in quantity supplied while a rise from an initially high price might bring on a less-than-proportionate rise in quantity supplied. Truck drivers can't stop when diesel fuel gets too expensive.

## How to Determine the Price Elasticity of Demand If demand in inelastic sales will not fall much due to price rise. Demand for normal goods increases during prosperity and decreases during regression. However, if demand for such goods in the importing country is elastic, then the exporting country will have to fix lower prices. This is because change in the price of a product will bring about a change in the quantity demanded depending upon the coefficient of elasticity. This helps the trade unions in knowing that where they can easily get the wage rate increased. It is a tool for measuring the responsiveness of one variable to changes in another, causative variable. The producers of cotton can gain maximum profit by setting high price of cotton, as demand of cotton in market is not easily altered.

## Practical Applications of Price Elasticity of Demand The coefficient of income elasticity of these goods is always positive. The Finance Minister has to take into account the elasticity of the product on which he proposes to impose the tax if the revenue for the Government is to be increased. Uses in Economic Policy regarding Price Regulation, especially of Farm Products—Governments of many countries, especially the United States of America, regulate the prices of farm products. The question here is : What should be the optimal tax on petrol which will reduce consumption by the desired amount? Demand elasticity helps firms model the potential change in demand due to changes in the price of a good, the effect of changes in prices of other goods, and many other important market factors. If demand for the product is elastic, then he will fix low price.

## Elasticity (economics) The high price of a product with demand remaining the constant helps in generating the large revenue for an organization. Now we will see how the supply and the demand can be classified according to the value of the elasticity. However, if the cross elasticity of demand equals a positive number, this means the two products measured are substitutive. A businessman chooses the optimum product- mix on the basis of elasticity of demand for various products. Thus a higher tax on a product, the demand for which is elastic, will re­duce the tax revenue of the government.

## Demand Elasticity/Elasticity of Demand This is because employers will move back to the left along this downward sloping demand curve for labour. They neither measure change of price in currency nor change of quantity demanded in weighs. Firstly, the concept of elasticity is crucial in the theory of price determination, especially under imperfect competition and monopoly. In this situation, public bus is an inferior good while the cab is a normal good. The advertisement elasticity is positive. They use different methods to calculate elasticity of demand including percentage, total expenditure and graphic.

## Types of Elasticity of Demand As a result output may increase to such an extent that 100 unemployed workers or even more are reab­sorbed by the firm. The resulting curve is downward-sloping; thus, increases in price result in a fall in demand for a given product. As a result output may increase to such an extent that 100 unemployed workers or even more are reab­sorbed by the firm. But this fear is not always true because use of machines may not reduce demand for labour. The success of the policy of devaluation to correct the adverse balance of payment depends upon the elasticity of demand for exports and imports of the country.
