Beyond Rationality: Deconstructing Behavioral Economics and Paternalism

Mario Rizzo, Professor of Economics at NYU, offers a critical perspective on behavioral economics, acknowledging its refreshing challenge to standard neoclassical assumptions but questioning its policy implications. He introduces the core concept of \"decision-making failure\" – where individuals act against their own best interests – as the foundation for behavioral policy analysis, drawing a parallel to market failure. Rizzo highlights the extensive catalog of cognitive biases, with \"present bias\" being a central example illustrating the conflict between short-run myopia and long-term rational decisions, which often forms the basis for interventionist policies.\n\nThe discussion then shifts to \"behavioral paternalism,\" which purports to guide individuals toward their \"bias-free true preferences,\" unlike classic paternalism based on objective criteria. Rizzo argues that discovering these bias-free preferences is an epistemically challenging task, often oversimplified by focusing on only one or two biases. He cites examples like the ineffectiveness of \"fat taxes\" or \"soda taxes,\" where studies show people often switch to alternatives (e.g., artificially sweetened sodas) or engage in compensatory eating, negating the intended health benefits. Similarly, he suggests that the success of automatic enrollment in retirement programs might stem more from increased information and employer recommendations than from a mere behavioral nudge.\n\nRizzo critiques the narrow definition of rationality in traditional economics, which demands complete preference ordering and consistency. He advocates for \"inclusive rationality,\" a broader standard that considers reasonable behavior, even if inconsistent, especially in contexts of high information costs or experimentation. He references economist Itsak Gilboa's pragmatic definition of rationality and psychologist George Ainslie's work, which suggests that some biases may have functional value and contribute to broader rationality, such as procrastination serving as a valuable timeout. Furthermore, Rizzo emphasizes Frank Knight's distinction between risk (known probabilities) and radical uncertainty (unknown future outcomes), arguing that many long-term decisions, like health risks, fall under uncertainty, making a single "unique rational decision" impossible to determine.\n\nFinally, the podcast explores the broader implications of paternalistic policies, particularly the substitution effect between external and internal self-control. Rizzo notes studies indicating that increased external control can diminish internal self-regulation, potentially generalizing to unrelated areas and making individuals less capable of self-management. He delves into the \"political economy of paternalism,\" describing it as a \"coalition of the bootleggers and the baptists\" often influenced by \"clueless voters,\" which can lead to an \"all or nothing\" political dynamic where interventions become increasingly severe due to the inherent difficulty in defining an optimal standard. Rizzo concludes by encouraging young economists to critically engage with mainstream approaches, noting a growing movement outside the mainstream (e.g., INET, Austrian school) that seeks to re-evaluate traditional notions of rationality.

what are the welfare implications of satisfying people's true preferences if they don't recognize that they are their true preferences does it make them happier in fact it might make them worse off

the fundamental concept of behavioral economics is something called decision-making failure... when individuals do not make decisions that are consistent with their own best interests

present bias is the idea uh that people when they're making decisions for the farther future tend to make quote-unquote rational decisions but when these decisions are upfront... people tend to be myopic

behavioral paternalism is a little different it it purports to be about not objective criteria but the true preferences of individuals what they really want to do not what somebody else thinks they should do

there are really important epistemic problems here that i think need to be further explored

we think that's too narrow there are plenty of reasons why people might be inconsistent in their choice that doesn't make them irrational it may be that they're experimenting with different options

inclusive rationality is the idea that we want to be broader about what we consider reasonable behavior so that reasonable behavior ought to be the standard not technically rational behavior

psychologists have done studies that indicate that self external control and internal control are treated by people as substitutes

the political economy of paternalism is uh is fraught really because it oftentimes it politically is a combination of what we call and has been called in the literature the coalition of the bootleggers and the baptists

you have to understand keynesianism better than the keynesians in order to criticize it so you have to understand standard new classical economics better than they do in order to criticize
