About the Book — Standard economics is predicated on rationality, operating with the presumption that buyers understand what they want and make rational decisions. However, in market economies, realities and complications exist. Buyers don’t always know what is best for them, and are susceptible to sly psychological and informational tactics (phools). And whenever there is profit to be made, sellers will try to take advantage by exploiting gaps in buyers’ knowledge, or lack thereof (phishing).
Phishing for Phools covers the economics of manipulation and deception, giving a coherent and compelling explanation of why markets can and do lead to undesirable outcomes, often resulting in widespread economic distress. Akerlof and Shiller make use of many examples to demonstrate how phishing works, on both macro- and micro-economic scales; in housing and automobile markets, with the acquisition of credit cards, from junk bonds to gym memberships, in drug and alcohol consumption, even showing how it was behind the financial crisis of 2008-2009.
This behavior generates a lot of misery no matter one’s socioeconomic status, but also, as the book argues, phishing is a symptom of an otherwise healthy economy. The goal is to isolate the bad, and the authors call for public education, civic engagement, and government regulation to combat the worst effects of phishing.
The authors make two distinct contributions to economic thinking. First, they propose a ‘phishing equilibrium,’ and argue that if one seller doesn’t exploit this profit opportunity, another will. This makes consumers pay more than they should and contributes to broad-based social anxiety. They also observe that while they enable economic growth, markets also create constant opportunities for phishing.
