What are the applications of income elasticity of demand?
Income elasticity of demand deals with how consumers respond to changes in their income. Generally, when individuals have a low income, much of it is spent on necessities like food, water, shelter, medical bills and clothing. But as ones income increases, less of it is spent on those necessities so save or spend on luxury items.
Is price elasticity of demand considered elastic or inelastic with food?
price elasticity of food would be inelastic, as there are no substitutes and food is a necessity.
What is the difference between price elasticity and cross elasticity of demand?
Cross price elasticity of demand measures how much demand of one good, say x changes when the price of another good, say y changes, holding everything else constant. For example, you can measure what happens to the demand of bread when the price of milk changes. The cross price elasticity is calculated as the percentage change in the quantity demanded of good x divided by the percentage change in the price of good y. If the cross price elasticity is negative, then we call such goods Complements (example: pizza and soft drinks -- they are consumed together). If the cross price elasticity is positive, then we call such goods Substitutes (example: pizza and burgers -- you usually consume either or). The income elasticity of demand measures the change in the quantity demanded of some good, when the income changes, holding everything else constant. For example you can measure what happens to the demand for expensive red wine when income increases. The income elasticity is calculated as the percentage change in the quantity demanded of the good divided by the percentage change in income. If the income elasticity for a good is positive we call them normal goods. It can be between 0 and 1, and we call it income inelastic demand for goods such as food, clothing, newspaper. If it is above 1, we call it income elastic demand. Examples are the red wine, cruises, jewelry, art, etc. If the income elasticity is negative, this means that as income increases, the quantity demanded for those goods actually decreases, we call those goods inferior goods. Examples are "Ramen noodles", cheap red wine, potatoes, rice. etc.

1 Define elasticity of demand Provide an example?
Responsiveness of the demand for a good or service to the increase or decrease in its price. Normally, sales increase with drop in prices and decrease with rise in prices. As a general rule, appliances, cars, confectionary and other non-essentials show elasticity of demand whereas most necessities (food, medicine, basic clothing) show inelasticity of demand (do not sell significantly more or less with changes in price).
Suppose good food's supermarket raises the price of its steak and finds its total revenue from steak sales does not change this is evidence that price elasticity of demand for steak is?
elastic
What has the author Greg M Allenby written?

Is there a difference between a normal good and inferior good?
Yes, a normal good is a good that's demand increases as your income increases, an inferior good is a good that's demand decreases when income increases. An example of a normal good, is easy to find, most goods are normal, meaning you want more of them when you have more money. An inferior good is something like fast food, as you earn more income, you will usually demand less of it.
What are the uses of price elasticity of demand to the business firms and to the government?
Elasticity measures help the sales manager in fixing the price of his product. The concept is also important to the economic planners of the country. In trying to fix the production target for various goods in a plan, a planner must estimate the likely demand for goods at the end of the plan. This erequires the use of income elasticity concepts.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 concept is also useful to the policy makers of the government, in particular in determining taxation policy, minimum wages policy, stabilization programmer for agriculture, and price policies for various other goods (where administered prices are used).The managers are concerned with empirical demand estimates because they provide summary information about the direction and proportion of change in demand, as a result of a given change in its explanatory variables. From the standpoint of control and management of external factors, such empirical estimates and their interpretations are therefore, very relevant.
Why has there been an increase in food poisoning?
World wide there is not an increase. What has increased is our demand from forgeign countries which do not have the same standards as we do for clean produce and food.
