    Economics is the science of how business works. As chemistry makes love work. Economics makes business work.

    Conventional wisdom can often be wrong. As outlined in Freakonomics by Steven Levitt, Levitt provides an in-depth discussion that shatters the conventional wisdom that most drug dealers are wealthy. His analysis of the financial records of a the Black Disciples, a Chicago gang, proved that most street-level dealers earned far less than minimum wage. In fact, they earned an average of three dollars an hour. With this story, the authors introduce the concept of a "winner takes all" labor market, as well as three other Freakonomics concepts. Concept 1: Winner Takes All Labor Market This describes a situation in which many laborers compete for a position in the market, but few actually succeed in finding employment. Those few who do are paid extraordinarily large salaries. In the example of the Chicago drug gang, only 2.2% of the members earned more than half the profits. Levitt and Dubner refer to this labor market as a “tournament.” A tournament, of course, refers to a situation in which many players compete against each other and, one by one, are eliminated. Similar dynamics exist in music, sports and entertainment. Concept 2: Supply, Demand & Equilibrium Price The example of the Black Disciples street vendors demonstrates an immutable law of economics: Whenever there are a lot of people willing and able to perform a job, that job doesn’t pay well. In a capitalist society, intense competition will drive prices down. If many people are able and willing to sell drugs for a gang, each person ends up competing with everyone else. This drives wages down. Concept 3: Incentives Matter Given the low wages and the fact that the chance of being violently and ignominiously murdered is one in four, why are so many willing and able to perform the job of dealing crack? This is because the winners in such a labor market are handsomely rewarded, and each budding drug dealer believes he or she can succeed.
