The rational decisionmaker
I hold individual preferences that are
self-interested, consistent, stable
I form beliefs that are rationalizable and based
on all available information
My choices reflect the best-possible course of action to ensure my own well-being
My decision process is to maximize my well-
being based on perceived constraints

What Is “Behavioral” Economics?
Behavioral economists contend that people deviate from these standard assumptions in ways that are (i) systematic and (ii)
significant for economic modeling
– Can be measured and modeled using insights from psychology, cognitive science and biology
– Have strong and testable implications for choice

Policy in a Rational World
Households choose what to consume
subject to their budget, given what goods and services firms produce
Firms choose what to produce and how to
produce it, given what consumers demand
Governments intervene to correct market failures i.e. socially suboptimal outcomes
Externalities Public goods Natural monopolies
Information asymmetry
Maximum ProfitMaximum Utility

Policy in a BE World

subject to their budget, given what goods and services firms produce
Firms choose what to produce and how to
produce it, given what consumers demand,
exploiting biases

For example, financial regulation
I hold individual risk and time preferences that are consistent, stable and self-interested
I form rational beliefs about my investment
choices and the market based on all the
information I have
Optimal portfolio conditionally maximizes
my private utility (subject to budget)
The regulator intervenes to ensure market efficiency and correct market failures
Investor education
Investor protection Disclosure Systemic risk
management Equity and
fairness

For example, financial regulation
E.g., CFPB mandate defines “abusive” practices as ones that among other things “take unreasonable advantage of…the inability of the consumer to protect the interests of the consumer in selecting or using a consumer financial product or service…”

Defaults for preventive care Pre-commitment to advance planning for finance and health care
“Automatic hovering” + incentives to promote desirable behaviors and socialization in smart city environment
Economicanalysis of alternatives
