Advocates of “libertarian paternalism” cite experimental evidence showing that people often make irrational decisions, and argue that we need government regulation to guard against such problems. Economist Richard McKenzie challenges part of this rationale by citing experimental evidence showing that markets actually give people incentives to act more rationally than they would otherwise, thus undercutting claims of irrational behavior based primarily on surveys or experiments that don’t mimic the incentives and other conditions of real-world markets:

People, including economists, are imperfect decision makers because of their mental limitations. But this fact does not mean that markets fail. Indeed, markets do far more than induce improved allocation of resources, given wants and resources. Markets induce market participants to be more rational than they otherwise would be because they must pay a price for being irrational. Thus, markets allow—no, require—economists to assume that people are more rational than they are likely to be found to be in laboratory settings, absent meaningful information and incentives and absent market pressures.

One underappreciated fact about the experimental and survey evidence relied on by advocates of the new paternalism is that it models voter decision-making far more closely than market decisions. Unlike market participants, voters have little or no incentive to either acquire information about the issues they decide, or to analyze the information they do have in an unbiased fashion. The same is true, to a lesser extent, of libertarian paternalist policies established by expert regulators insulated from democratic control (the “rule of experts” is often proposed as a means by which paternalist regulation can be enacted without being influenced by voter ignorance and irrationality). Such regulators may be more knowledgeable than voters. But unlike consumers, they do not have their own money at stake, and therefore don’t suffer any penalty if they [...]

Advocates of the “new paternalism” (sometimes also called “libertarian paternalism”) argue that carefully calibrated government interventions can help consumers avoid mistakes caused by their own cognitive biases. In this interesting new article, economist Mario Rizzo and legal scholar Glen Whitman argue that new paternalist policies are vulnerable to slippery slopes that will extend them far beyond the areas where they might be genuinely need to correct consumer errors. Here is the abstract:

The “new paternalism” claims that careful policy interventions can help people make better decisions in terms of their own welfare, with only mild or nonexistent infringement of personal autonomy and choice. This claim to moderation is not sustainable. Applying the insights of the modern literature on slippery slopes to new paternalist policies suggests that such policies are particularly vulnerable to expansion. This is true even if policymakers are fully rational. More importantly, the slippery-slope potential is especially great if policymakers are not fully rational, but instead share the behavioral and cognitive biases attributed to the people their policies are supposed to help. Accepting the new paternalist approach creates a risk of accepting, in the long run, greater restrictions on individual autonomy than have been heretofore acknowledged.

I have myself previously criticized the new paternalism here, here, here, and here. Rizzo and Whitman argue that the danger of slippery slope effects is greater if policymakers themselves suffer from cognitive biases. In this post, I pointed out that the voters who elect the policymakers also suffer from ignorance and cognitive bias, often to a greater extent than the consumers whose biases new paternalist policies are intended to correct. Giving more power to cognitively biased government officials elected by rationally ignorant and cognitively biased voters is likely to exacerbate the effects of cognitive error more [...]
