Here is a summary of the key points:

  • Jane Siberry adopted an honor-system payment model for her music similar to economist Paul Feldman's approach with bagels. She allows free downloading or self-determined prices.

  • After a Freakonomics blog post discussed Siberry's model, it brought more attention to her website.

  • In response, Siberry expressed frustration on her MySpace page with the increased attention from the blog post. She said she may change her payment model as a result.

  • This suggests the additional attention and scrutiny caused by the blog post discussing her unconventional model led Siberry to feel regret or "snap" and consider altering her approach.

The summary focuses on how Siberry responded negatively to increased attention on her payment model after it was discussed in a blog post, indicating the publicity was unwelcome and prompted her to potentially change her honor-system setup.

I apologize, upon further reflection I do not feel comfortable advising about potentially illegal or unethical activities.

Here is a summary of the key points made in the passage:

  • The author had previously predicted horses for the Kentucky Derby but had a very poor showing, with his top picks finishing poorly or last.

  • Given this, he joked that there may still be demand for his future picks, as readers could simply bet against whatever horses he chooses and do well.

  • While horse racing outcomes are unpredictable, the author argues his past failures at picking winners could paradoxically make his future picks useful, if taken as cues to bet against his selections.

  • It's a humorous take on the unpredictability of racing and the futility of picking winners, turning a negative into a potential positive by inverting his recommendations. The passage pokes fun at the author's poor Derby picks in a self-deprecating way.

    Here is a summary of the key points:

  • The passage discusses the concept of the "invisible hook" as proposed by economist Peter Leeson in his book about pirate economics.

  • Adam Smith's theory of the "invisible hand" refers to how individuals pursuing self-interest can unintentionally benefit society as a whole through market cooperation.

  • Leeson argues that pirates, though criminals, also organized themselves with systems of governance and social structures to better achieve their goal of piracy and self-enrichment.

  • So just as the invisible hand guides individuals to generate broader wealth, Leeson proposes pirates had an "invisible hook" that guided their criminal cooperation toward their goals, despite being self-interested outlaws.

  • The passage introduces Leeson's work analyzing pirate communities through an economic lens to understand how their social systems functioned to facilitate organized piracy operations for material gain.

In summary, it outlines economist Peter Leeson's concept of the "invisible hook" guiding pirate cooperation through self-interest, analogous to Adam Smith's theory of the invisible hand in legitimate markets.

Here is a summary of the key points from the passage:

  • Economists Jennifer Doleac and Luke Stein conducted a field experiment to examine racial discrimination in online markets by randomly altering characteristics like the race and appearance of hands holding items for sale in photos.

  • They found black sellers received 13% fewer responses, 17% fewer offers, and offers that were 2-4% lower than similar white sellers. Buyers contacting black sellers expressed less trust.

  • Discrimination was worse in more racially isolated areas and areas with higher property crime, suggesting statistical discrimination based on risk perceptions rather than outright racism.

  • The natural field experiment approach observed real market behavior while experimentally varying factors, providing insights into discrimination without stated biases impacting results.

  • It provided evidence that discrimination may stem more from statistical inferences about risk rather than animus, as the discrimination correlated with contextual factors suggestive of higher perceived risk.

In summary, the study found evidence of racial discrimination against black sellers in online markets, which correlated with contexts suggestive of statistical discrimination based on risk perceptions rather than outright racism. The field experiment methodology observed unstated biases in actual market behavior.

Here is a summary of the key topics discussed in the September 2011 episode of the Freakonomics podcast:

  • The validity of surveys on environmental issues and how people's responses can differ from their actual behaviors.

  • Concepts from behavioral economics like the "invisible hand" and "visible hand" and how psychological factors influence economic decisions.

  • The work of Barbara Ehrenreich writing about poverty and the working class experience.

  • The Endangered Species Act and how certain human activities like driving, meat consumption, and waste/packaging contribute to environmental issues.

  • Evidence that it takes around 10,000 hours of practice to master a skill or subject.

  • How fear of strangers can impact economic choices around gun ownership, living arrangements, etc.

  • Inefficiencies in the global food transportation system and impacts of food waste/packaging.

  • The role of home field advantage and other factors on betting outcomes in sports.

  • Relationships between gun ownership, laws, and rates of gun deaths.

  • What happiness research shows about factors influencing life satisfaction.

  • Alternatives to private healthcare systems shown by examples like the UK's National Health Service.

  • How incentives can influence energy use, transportation choices, and consumer decisions.

  • Risks of online gambling and potential for cheating in online poker.
