In classical economics, decision-makers are assumed to be rational actors who maximize utility. However, behavioral economists have identified numerous cognitive biases that lead to systematic departures from rationality. To address these biases without restricting choice, researchers introduced the concept of 'nudges'—subtle changes in the choice architecture that steer individuals toward optimal decisions. While initial studies demonstrated that nudges can significantly increase retirement savings and healthy food choices, recent meta-analyses have questioned their long-term efficacy and generalizability across diverse cultural contexts, prompting a call for more robust research designs.
Which choice best describes the overall structure of the text?
- AIt compares two competing theories of human behavior, details a series of experiments testing both theories, and argues that one theory has been definitively disproven.
- BIt defines a specific cognitive bias, explains how that bias affects financial decision-making like retirement savings, and proposes a policy change to eliminate the bias.
- It outlines a foundational economic assumption, introduces an intervention designed to address departures from that assumption, and highlights both the initial success and subsequent scrutiny of that intervention.Answer
- DIt details a history of economic thought, explains how traditional models have replaced modern behavioral theories, and calls for an end to experimental research in economics.
