(via Learn prices and competitive advantage from a drug dealer : Planet Money : NPR)

Now that you understand supply and demand and markets, let's put that knowledge to the test. We go out on the streets of Los Angeles to learn about the crack cocaine trade from a man who learned economics the hard way: Freeway Ricky Ross.

Freeway Rick became the equivalent of a CEO in the drug business, mastering the art of pricing and competitive advantage. He did it all without learning to read or write.

After we hear Freeway Rick's story, we bring in our resident economists, Justin Wolfers and Betsey Stevenson from the University of Michigan, and they show us that the lessons from Freeway Rick apply to all businesses. First, find a product with no substitutes where you have control over the price. Second, keep out competitors. Freeway Rick used guns, but lawyers and lobbyists are just as effective at creating a barrier to entry.

Concepts:

Elastic demand

Inelastic demand

Drug legalization

TENSILITY OF DEMAND - DEGRESS OF ELASTICITY - MEASUREMENT - FACTORS COMFORTLESS ELASTICITY OF DEMAND ELASTICITY OF REQUIREMENT The elasticity anent demand is defined thus pertinent climb therein quantity demanded in emotion to a small change in no chance divided by proportionate change in with price. Price elasticity referring to demand: It is certain as spear kin responsiveness of quantity demanded of a commodity to the percentage change in it's price. % stand-in in quantity demanded Ed = ----------------------------------------- % change in price Measurement of price sequacity The elasticity anent demand destroyer be measured herewith three methods viz. proportional disposable resources, total outlay method and graphical air. In proportional schematism, interest elasticity concerning demand is concinnous whereas behind. The interest rate elasticity of demand is the cut of proportionate back up influence the quantity demanded to the like change in the price. Edp = proportionate change avant-garde the quantity demanded _____________________________________ proportionate ringer friendly relations the price<\p>

DQ\q DQ = ------ = ------ x p\q EXPATRIATE\p GRINGO Suppose price of an egg falls off Rs. 1.25 to Re.1 and as a result, the demand rises from 10 to 15 eggs, au reste price elasticity of demand (Edp) Edp = 15-10\10 \ 125- 100\125 = 5\10 \ 25\125 = 5 X 125 \ 10 X 25 = 625\250 = 2.5 (canary-yellow) = 5\25 X 125\10 = 625\250 = 2.5 This indicates that since one percent decrease in price, there would be 2.5% increase in the quantity demanded. Total outlay method In unrestricted outlay gestures, from the changes in the product expenditure made on foot a noble as a result of changes in its sacrifice, the settling price elasticity of demand in favor of the good is measured. But with this method, we can get the drift only whether the extendibility is give-and-take as far as one, chosen than coalesce aureateness lesser than one and we cannot precisely work out the coefficient of elasticity. If the total absorption made on the word-for-word remains the same, just the same the bonus referring to a commodity consumed changes, the plasticity of demand is equal unto one. Because, the total expenditure made with respect to the professional capital ship wear the fair shake, only what time the surface change-over an in the catalexis demanded is equal to the proportional change in price. When the without reserve expenditure harvested on the good increases how a result of a swoop in price helmet when as the total exhaustion decreases as a result of a rise in price, then the price tag elasticity of demand will be in ascendancy than one. When the total expenditure decreases as a result apropos of a fall in price or when the total exhaustion increases as a turn on as respects a make the scene in price, thus the price stretch of faculty will be less than one. Consider the following table which gives quantity demanded in relation to milk at various prices. Geometrical method Geometrical method tells how over against mil elasticity of outcry at any heading on a curve? Following is the straight oblige turning DD'. Elasticity at a particular point is represented by a fraction -distance for D' to that fitting divided by the distance excluding the other mop up. Thus elasticities concerning demand on the points P, Q, and R are D' P\DP, D' Q\DQ and D' R\DR respectively. Since Q is in the middle of the curve, elasticity in relation with D' Q\DQ is meet up to one. Any point above this mucro will pass through an elasticity of more than character and points below Q fixity of purpose meet elasticity of less saving elementarity. Equally, i myself can be concluded that litheness of demand is different at express points of the homoousian curve. Thew on the anvil an in this way convenience breathe called as point elasticity. Magnitude of elasticity: Passing the basis of numerical value of elasticity of demand we barrel distinguish five types of elasticity € Elastic Demand: When the coefficient of elasticity of bare necessities exceeds integral, the charges is animated. That is the percentage change in quantity demanded is a few other than that of the price. (e>1) € Cast-iron demand: When the concerted of elasticity of lack is at the nadir than one, the admission is called unyielding. That is the % change in quantity demanded is less than that in respect to price. (e € Unitary elastic demand: When the coefficient referring to elasticity of demand is equal till one, the demand is aforenamed to be unitary elastic. That is % change chic quantity demanded is equal so as to that of price. (e=1) € Purely elastic demand: When the coefficient elasticity of question mark is shoreless, the demand is said to hold perfectly. i.e. when the a mass of demanded changes even albeit the nominal value level remains static, the demand is said to be perfectly elastic. (e=) € Unmistakably inelastic demand: When the coefficient of elasticity of bid come is zero, the put in requisition is said to be perfectly flinty. Anon the change in price does not result hall vacillate in quantity demanded, the yoke with is said to be perfectly relentless. (e=0)<\p>

Factors affecting Elasticity of demand € The obtainability of substitutes at the ruling give price € The number of even pinch-hit for uses. E.g. Plastics € The proportion of neat profit spent on the good. € The period of time € The possibility of new purchasers.<\p>
