INTRODUCTION: The Hidden Side of Everything
In which the book’s central idea is set forth: namely, if morality represents how people would like the world to work, then economics shows how it actually does work.
Why the conventional wisdom is so often wrong . . . How “experts”— from criminologists to real-estate agents to political scientists—bend the facts . . . Why knowing what to measure, and how to measure it, is the key to understanding modern life . . . What is “freakonomics,” anyway?

1. What Do Schoolteachers and Sumo Wrestlers Have in Common?

In which we explore the beauty of incentives, as well as their dark side—cheating. Contents

Who cheats? Just about everyone . . . How cheaters cheat, and how to catch them . . . Stories from an Israeli day-care center . . . The sudden disappearance of seven million American children . . . Cheating schoolteachers in Chicago . . . Why cheating to lose is worse than cheating to win . . .
Could sumo wrestling, the national sport of Japan, be corrupt? . . . What the Bagel Man saw: mankind may be more honest than we think.
2. How Is the Ku Klux Klan Like a Group of Real-Estate Agents?

Freaknames

...Segregation” (Levitt) (Freakonomics ). There are names that are different between African American and Caucasians but, none of these shouldn’t define you as a person or create a image for yourself. First, does your name cause a problem in the work force? According to Levitt and Dubner, they created a experiment by typing up 5000 of the same resume and just changing the names to half caucasion names to the other half African American names. The resume were sent out to companies acrossed from Chicago and New York. 33% African American names are less likely to get an interview then a Caucasian name. When someone is looking for a job with a Casucasin name in ten weeks they are most likely to get a job but if an African American would take fifteen weeks being unemployed. (Freakonomics ) When African Amercians can get an opportunity in the work force they generally earn less compared to a Caucasians person. As giving your child a name that is “Uneek” can be harder for them in the work force. Also, can living in a different society or coming from a different background change the view on your name? In the 50s African American had basic names such as John or Micheal and etc.,but the Black Power movement began in the 80s and wanted African American to define who they were so they started to make names up so people would realize who they were. Parents that were unmarried and had lower education was most likely to name their child with an unique name (Freakonomics ). But when......

Levitt And Dubner's Freakonomics

...Freakonomics by Steven D. Levitt and Stephen J. Dubner focuses on our economy and the study of incentives. The two authors discuss comparisons that seem so foreign such as “What do school teachers and sumo wrestlers have in common?” and “How is the Ku Klux Klan like a group of real-estate agents?” Questions like these stir up the novel and essentially unravel the untold stories of life and consumption. Core economic principals are discovered within each story of the book. The title Freakonomics in itself has a humorous connotation with the combination of two words: freak and economics. Freak, by definition, means abnormality or oddity and most people might familiarize economics solely with finance or commerce. However, Levitt and Dubner break this common misconception and reveal how...

Freakonomics

...Freakonomics, Steven D. Levitt, Stephen J. Dubner "(Feldman wondered if perhaps the executives cheated out of an overdeveloped sense of entitlement.What he didn't consider is that perhaps cheating was how they got to be executives.)... If morality represents the way we would like the world to work and economics represents how it actually does work, then the story of Feldman's bagel business lies at the very intersection of morality and economics"(46)Levitt, and Dubner. Levitt implements his first rhetorical device, diction, through the use of the phrase "overdeveloped sense of entitlement", this shows that the belief of the author, was that they were stealing simply because they felt that their higher social status made it ok. However the connotation that comes with the word "entitlement" under the circumstances it is used makes me think of more of a snobby stereotypical movie rich persona, such that in a typical celebrity matter they feel that they are in fact above the law.The second thing he does is use italics to emphasize the word "be", the purpose of emphasizing be in this case is to show the contrasting in between his ideas, and of the Feldman, the business man. It also seems to shine an eerie light on to the fact that perhaps, the cheating to get ahead in the corporate ladder was the same principle they applied to stealing the bagels, it was ok, as long as they didn't get caught. Levitt's final rhetorical device was a metaphor when he says " If morality represents......

Xvc Cost of Soemthing

...The Value of Curiosity- Exploring the Hidden Side of Everything Freakonomics, by Steven Levitt and Stephen Dubner, is an important economical book that shows examples of economics that most people do not understand or realize. This book displays the value of incentives, how the average consumer does not know much about the markets they buy in, cause and effects of these markets, and showing the distrust in most experts. To me, it proves that an average person can’t really look at the economic trends of a lot of markets because the patterns and information are so deep, that the average consumer can’t just ‘dig’ up. Freakonomics allows hidden information and small things that mean so much to come to surface, so the economy that surrounds us can be better understood for a more promising financial future. In chapter one, Levitt and Dubner really focus on incentives. Incentives are the motivator in which I do everything in my life. Sometimes incentives strike negative behavior in people because the amount of power in the motivation. In the chapter, they demonstrate three examples of this bad behavior. The remainder of this chapter brings together schoolteachers, sumo wrestlers, and a bagel salesman. The school teachers are under so much pressure to present excellent grade scores by their students in order to look good in front of the state, that they lose focus in the actual importance. Teachers begin to teach for a test and not for the benefit of the children’s futures. I......

Freaky Economimcs

...Langstaff Hnrs Economics Critical Analysis March 11, 2013 Freaky Economimcs Which is more dangerous, a gun or a swimming pool? What do schoolteachers and sumo wrestlers have in common? Why do drug dealers still live with their moms? How much do parents really matter? Why am I asking you all of these seemingly irrelevant questions? Well I’ll tell you why, because to economists Steven D. Levitt and Stephen J. Dubner, these questions aren’t irrelevant at all. “The conventional wisdom is often wrong” (Levitt Dunbar 14) so Levitt looks at the economy in a very unconventional way. Often times, the study of economics is seen as dry, boring, and consisting of mind numbing numbers, uninteresting financial trends, and statistics. Yet in Freakonomics Levitt and Dubner make it interesting, and dare I say, funny. They show us that economics is the study of incentives and how people get what they want, or need, and especially when other people want or need the same thing. I’m very fond of the idea that there is no one cause for an effect. I believe that there are multiple tiny causes that build up over time and then suddenly, and oddly to many people’s surprise, you have this looming and terrible effect. So I was a bit put off at how Levitt only offers one cause for some of the arguments he tries to make. He even says himself in the introduction that, "If you learn how to look at data in the right way, you can explain riddles that otherwise might have seemed impossible.”......

Freakonomics

...MIGUEL, Karl Ann D. INTSOCI C33 Freakonomics by Stephen Levitt and Stephen J. Dubner Introduction: The Hidden Side of Everything There are several things required to understand the world through economics: first, knowing the incentives of all parties; second, realizing that conventional wisdom is usually wrong; third, understanding that most effects have subtle and distant causes and the most obvious is often the wrong one; fourth, specialists like salesman and lawyers use obscure knowledge to achieve their own ends and the internet helps to erode this advantage by making knowledge more freely available to people; lastly, data is invaluable to understanding the world. Chapter 1: What Do Schoolteachers and Sumo Wrestlers Have in Common? People all learn to respond to incentives, whether positive or negative from the outset of life. An incentive is simply a means of urging people to do more of a good thing and less of a bad thing. There are three basic flavors of incentive: economic, social and moral. Economic incentive is something material or tangible; moral is based of self-judgments; social is terribly powerful as it depicts what other people think of you resulting from your own actions or choices. Any incentive is inherently a trade-off; whatever the incentive, whatever the situation, dishonest people will try to gain an advantage by whatever means necessary. Cheating is a natural act getting more for less. The government required the High-Stakes Testing as part......

They Say I Say

...They Say/I Say Journal 1 Subject: Freakonomics Chapter 1 “School Teachers and Sumo Wrestlers” They Say: In this chapter the author, Steven D. Levitt and Stephen J. Dubner, define the economic as root to pursue of incentives. The author define an incentive as “a means of urging people to do more of a good thing of a bad thing”. Sometimes these incentives are so irresistible that people are driven to obtain them through a bad behavior. In addition the authors describe some circumstances of cheating. There is an analysis of data to detect some cheating patterns. The most prominent cases are included the Chicago public schools teacher who changed answers on their students’ test, and Japanese sumo wrestlers who conspired to discard certain high stakes matches. Basically the main point of this chapter analyzed different scenarios to explain that humans always are looking for incentives. These incentive are categorized as economic, social, and moral. All of this, are explained in a different scenarios starting with the situation of the day care and finalized with the business man who run a bagel business. The author focused at the end explaining that humans are honest even when no one is watching them. I say: I am completely agreed with the ideas described by the author in this chapter related how human behavior depends of the incentives. To better understanding of these behavior the author states that: “economists love incentives....The typical economist believes the world...

Discrimination in the Workplace

...discrimination has been around for years. However, there are laws that try to protect employees from that type of behavior today. The Employment Non-Discrimination Act (EDNA) prohibits discrimination in the workplace based on gender, race, disability, and recently included, sexual orientation (Anonymous, 2009). Yet despite existing laws about discrimination, many employees still suffer from some type of discrimination or harassment in the workplace. I will discuss the most common types of discrimination and some solutions that may work in your organization. Sexism is still prevalent even in 2009. For example co-authors Levitt and Dubner were featured on ABC’s 20/20 promoting their new book called Super Freakonomics which is the sequel to their original book called Freakonomics. On the show Steven Levitt stated that, “Women’s liberation has been great for high end prostitutes but not for our children.”(2009) Levitt and Dubner believe that in the 1940’s, more than half of Americas brightest women were schoolteachers. Now they have gone on to become doctors, lawyers, and bankers. Therefore, teachers are now left up people that are not as qualified. Levitt stated that successful women with MBA’s end up marrying men with MBA’s and staying home. This is the reason they are not paid as well. They believe that men are motivated by money and women are motivated by families. The authors go on to say that it is not discrimination that caused the “glass ceiling”, it is motivation.......

...Is there a causal link between the drastic crime-drop , at the turn of the millennium , to the remote event of the legalization of abortion in the mid 90 's ? Steven Levitt and Stephen Dubner would have us believe , in their movie Freakonomics , that there is a statistically definable and clear relationship between the decision of the Supreme Court in Roe v .Wade and the reduction of criminality In brief , they posit that the legalization of abortion in the 70 's set into motion a chain of causal events which would eventually lead to a dramatic decrease in criminal incidence and crime rates in the last twenty years . The argument is buttressed by the fact that the statistical data in the rise of legalized abortion appear to militate criminal incidence throughout the country .
 In the decision of the Court , the majority believe that the woman has the right to decide whether or not to continue with the pregnancy .However , such right is not absolute since the moment the first trimester ends , the State acquires the right to prevent or intervene with such 
decision by the mother because of a valid compelling state interest . At any rate , the Supreme Court reveals that this will help reduce the incidence of bearing unwanted children and causing more trauma for both the mother and the child in the long run . Levitt and Dubner , on the 
hand , added color into this line of argument by stretching the correlation of unwanted children to either the rise or fall of crime. The less...

Freakonomics Summary

...Working paper Summarization The term Asymmetric information is defined as the unequal knowledge possessed by the parties to a market transaction. Information is crucial for buyers and sellers in the business world today, and sometimes the buyers don’t always have all the information. The second chapter in the book FREAKONOMICS tells us how individuals, organizations, and businesses often exploit their access to crucial information at the expenses of others. The KKK used to be a very profitable organization in America until the 1940’s. Stenson Kennedy had a hatred for the Klan, and in the 1940’s joined the KKK to exploit the Klan’s secrets. What Kennedy found was the Klan was a slick moneymaking organization for those near the top of the organization. The Klan had a number of revenue sources: thousands of dues from membership fees, businesses that would hire the Klan to scare off unions, or pay the Klan protection money, and Klan rallies that generated huge cash donations. When Kennedy discovered this he wrote a letter to the governor of Georgia requesting the charter be revoked. The reason for this was the Klan had been designated a non profit organization, but Kennedy had proof it was clearly devoted to profit. Kennedy still wasn’t getting the desired affect he wanted because even though this would damage the clan in Georgia there would still be other clans around the country that wouldn’t be hurt. He then decided to turn to the radio, once he knew the secrets of......

Freakonomics

...Freakonomics The book, Freakonomics by Steven Levitt and Stephen Dubner, addresses a variety of questions that one may not typically ask. From finding connections between school teachers and sumo wrestlers to addressing the issue of crime through legalizing abortion, this book provides an interesting perspective on issues and real life situations, one that most people are not unable to make out at first sight. Firstly, Levitt attempts to analyze the issue of crime which has become relatively commonplace in the early 1990's. A generation of young teenage criminals have arisen and roamed the streets, threatening to create all kinds of pandemonium. This increase of crime rates led many criminologists, political scientists, and forecasters to believe that there will continue to be a spike in murders by teenagers in the upcoming years. Surprisingly, the opposite held true and crime deteriorated at a fast rate. Here, Levitt unravels the misconception that the roaring 1990s economy, proliferation of gun control laws, and innovative policing strategies did not contribute to the plummet of crime rates. Rather, we need to shift our attention to the legalization of abortion laws which, according to Levitt, what was actually led to the decrease of crime rates. Levitt draws the connection between crime rates and legalizing abortion by introducing a young Dallas woman named Norma McCorvey, who had already given up her two children for adoption but found herself pregnant once again....

I don’t agree with this option because even it is good for AH biotech Company, but for those how are in Albania suffering from anxiety attacks will stop there free treatment and cannot afford after marketing the Drug and it will be difficult for them to buy it as they are poor people. 2. Do the clinical trials in the United States. Even though it will certainly be more expensive and time-consuming, you’ll feel as if you’re living up to the part of the Hippocratic Oath that instructed you to “prescribe regimens for the good of my patients according to my ability and my judgment and never do harm to anyone.” In my view this is the best option for hassan, even though it is expensive to conduct the tests in the US, because the based clinical studies are far more stronger and in turn will give the company higher returns in the future, also the patients in the US can afford the treatment after the initial free doses are given by the investigators because of the insurance system in place. 3.

...Chromatography INTRODUCTION IN THIS LAB, WE WILL BE EXPRESSING THE GREEN FLUORESCENT PROTEIN (GFP) IN BACTERIA AND PURIFYING IT USING COLUMN CHROMATOGRAPHY. THE SPECIFIC TYPE OF CHROMATOGRAPHY WE WILL BE USING IS HYDROPHOBIC INTERACTION CHROMATOGRAPHY (HIC). THE FOLLOWING IS INFORMATION FROM BIO-RAD INC., THE SUPPLIER OF THE REAGENTS: GFP has several stretches of hydrophobic amino acids, which results in the total protein being very hydrophobic. When the supernatant, rich in GFP, is passed over a HIC column in a highly salty buffer (Binding Buffer), the hydrophobic regions of the GFP stick to the HIC beads. Other proteins which are less hydrophobic (or more hydrophilic) pass right through the column. This single procedure allows the purification of GFP from a complex mixture of bacterial proteins. Loading the GFP supernatant onto the chromatography column When students load the GFP supernatant onto their columns, it is very important that they do not disturb the upper surface of the column bed when performing the chromatography procedure. The column matrix should have a relatively flat upper surface. A slightly uneven column bed will not drastically affect the procedure. However, subsequent steps of loading, washing, and eluting should minimize disrupting the column such that beads "fluff up" into the buffer. When loading the GFP supernatant onto the column, the pipette tip should be inserted into the column and should rest against the side of the......
