Economics without Preferences

A new microeconomics when agents lack the preferences that economics normally relies on. Parts of economic orthodoxy go out the window: prices can be volatile, cost-benefit analysis no longer supplies easy answers. This book offers policy alternatives that deliver the productivity growth that capitalism can potentially provide.

Economics without Preferences lays out a new microeconomics - a theory of choice behavior, markets, and welfare - for agents who lack the preferences and marginal judgments that economics normally relies on. Agents without preferences defy the rules of the traditional model of rational choice but they can still systematically pursue their interests. The theory that results resolves several puzzles in economics. Status quo bias and other anomalies of behavioral economics shield agents from harm; they are expressions rather than violations of rationality. Parts of economic orthodoxy go out the window. Agents will fail to make the fine-grained trade-offs ingrained in conventional economics, leading market prices to be volatile and cost-benefit analysis to break down. This book provides policy alternatives to fill this void. Governments can spur innovation, the main benefit markets can deliver, while sheltering agents from the upheavals that accompany economic change.
