The book's chapters cover: Chapter 1: Discovering cheating as applied to teachers and sumo wrestlers, as well as a typical Washington, D. Chapter 5: The negligible effects of good parenting on education Chapter 6: Steven Levitt Essays socioeconomic patterns of naming children nominative determinism One example of the authors' use of economic theory involves demonstrating the existence of cheating among sumo wrestlers.
Steven Levitt Essays In a sumo tournament, all wrestlers in the top division compete in 15 matches and face demotion if they do not win at least eight of them. The sumo community is very close-knit, and the wrestlers at the top levels tend to know each other well.

Statistically, the 7—7 wrestler should have a Steven Levitt Essays below even chance, since the 8—6 wrestler is slightly better. Levitt uses visit web page statistic and other data gleaned from sumo wrestling matches, along with the effect that allegations of corruption have on match results, to conclude that those who already have eight wins collude with those who are 7—7 and let them win, since they have already secured their position for the following tournament. Despite condemnation of the claims by the Japan Sumo Association following the book's publication inthe Grand Tournament in Tokyo was canceled for the first time since because of allegations of match-fixing. The authors posit that various incentives encourage teachers to cheat by assisting their students with multiple-choice high-stakes tests.

Levitt asks, "What would the pattern of answers look like if the teacher cheated? Second edition[ edit ] In Chapter 2 of Esxays, the authors wrote of their visit to folklorist Stetson Kennedy 's Florida home where the topic tSeven Kennedy's investigations of the Ku Klux Klan were discussed. In the "Revised and Expanded Edition" this embellishment was noted and corrected: "Several Steven Levitt Essays after Freakonomics was first published, it was brought to our attention that this man's portrayal of his crusade, Steven Levitt Essays various other Klan matters, was considerably overstated Israeli economist Ariel Rubinstein criticized the Steen for making use of dubious statistics and complained that "economists like Levitt This paper has Steven Levitt Essays much controversy, to which Levitt has said The numbers we're talking about, in terms of crime, are absolutely trivial when you compare it to the broader debate on abortion.
From a pro-life view of the world: If abortion is murder then we have a million murders a year through abortion. And the few Leevitt homicides that will be prevented according to our analysis are just nothing—they are a pebble in the ocean relative to the tragedy that is abortion. So, my own view, when we [did] the study and it hasn't changed is that: our study shouldn't change anybody's opinion about whether abortion should be legal and easily available or not. It's really a study about crime, not abortion. Inthe authors published a response, [8] in which they argued that Joyce's argument was flawed due to omitted-variable bias. In NovemberFederal Essay About Pirates Bank of Boston economist Christopher Foote and his research assistant Christopher Goetz published a working paper, [9] in which they argued that the results in Donohue and Levitt's abortion and crime paper were due to statistical errors made by the authors: the omission of state-year interactions and the use of the total number of arrests instead of the arrest rate in explaining changes in the murder rate.
When the corrections were made, Foote and Goetz argued that abortion actually increased violent crime instead of decreasing it and did not affect property crime.

The Economist remarked on the news of the errors that "for someone of Mr Levitt's iconoclasm and ingenuity, technical ineptitude is a much graver charge than moral turpitude. To be politically incorrect is one thing; to be simply incorrect click the following article another. The authors argued that, after making necessary changes to fix the original errors, the corrected link between Steven Levitt Essays and crime was Stevne weaker but still statistically significant, contrary to Foote and Goetz's claims. Foote and Goetz, however, soon produced a rebuttal of their own and said that even after analyzing the data using the methods that Levitt and Donohue recommend, the data does not show a positive correlation between abortion rates and crime rates.
Freakonomics commented on the effects of an abortion ban in Romania Decreestating that "Compared to Essay children born just a year earlier, the cohort of children born after the abortion ban would do worse in every measurable way: they would test lower in school, Steven Levitt Essays would have less success in the labor market, and they would also prove much more likely to become criminals. John DiNardo, a professor at the University of Michiganretorts that the paper cited by Freakonomics states "virtually the opposite of what is actually claimed": On average, children born in just after Steven Levitt Essays became illegal display better educational and labor market achievements than children born prior to the change.

This outcome can be explained by a change in the composition of women having children: urban, educated women were more likely to have abortions prior to the policy change, so a higher proportion of children were born into urban, educated households. Pop-Eleches,p. Children born after the abortion ban attained more years of schooling and greater labor market success. This is because urban, educated women were more likely to have abortions prior to Steven Levitt Essays policy change, and the relative number of children born to this type of woman increased after the ban.
