Individual Choice and Social Welfare with Viktor Vanberg

Episode Summary

Executive Summary: Victor Van Berg argues that economics should abandon "normative economics" in favor of "applied economics": economists should give hypothetical, testable advice to specific addressees based on their goals, not pronounce social values. He extends this to public choice and constitutional economics, emphasizing that policy outcomes depend on rules of the game and that economists should focus on institutional reform, incentives, and mutual gains rather than assuming social welfare maximization.

Main Topics: From political economy to economics (Priority: 5/5): Van Berg explains why economists dropped "political economy": they wanted scientific legitimacy and to avoid explicit value judgments, even though policy advice remained central to the discipline. Applied economics vs. normative economics (Priority: 5/5): He argues economics should be framed as applied science, like engineering, where advice takes the form of hypothetical imperatives tied to the addressee's own goals and is therefore testable and refutable. Social welfare, addressees, and methodological individualism (Priority: 5/5): Van Berg criticizes welfare economics for assuming a social-welfare-maximizing decision-maker, insisting that only individuals choose and that economists must identify who the advice is actually for. Politics, incentives, and public choice (Priority: 5/5): He says politicians and bureaucrats do not necessarily share the public's welfare-maximizing goals, so public choice theory is needed to analyze political failure just as welfare economics analyzes market failure. Buchanan and constitutional economics (Priority: 5/5): Van Berg presents Buchanan's contribution as shifting the focus from diagnosing failures to reforming the rules of markets and politics so that institutions better align private incentives with the common interest. Rent seeking and special privileges (Priority: 4/5): The discussion emphasizes how special interests lobby for protection and exemptions, producing social losses when everyone seeks privileges while wanting competition for others. Competition, mutual gains, and social contract (Priority: 4/5): He uses Adam Smith and Buchanan to argue that market competition and constitutional rules can generate mutual gains, but only if the rules prevent producer interests from overriding consumer interests.

Key Arguments: Economics became "economics" rather than "political economy" because economists wanted to appear value-free and scientifically rigorous, but policy relevance never disappeared. Applied economics should replace the label "normative economics" because advice can be framed as hypothetical imperatives: if an agent wants goal Y, then policy X is a suitable means. Such advice is scientific because it is testable, refutable, and incomplete if alternative means exist or if the addressee does not share the goal. Welfare economics often omits the crucial question of who the addressee is; without a real decision-maker seeking social welfare, social-welfare-maximizing recommendations have limited practical force. In democratic politics, politicians maximize re-election prospects and bureaucrats have their own incentives, so economists cannot assume political actors will pursue the public interest automatically. Public choice theory is the necessary counterpart to welfare economics because it studies political failure just as welfare economics studies market failure. Buchanan's constitutional economics goes further by asking how rules themselves should be designed to generate mutual gains and limit rent seeking. Adam Smith's insight about self-interest works only under competitive rules; competition and institutional constraints, not self-interest alone, align private and public interests. Special-interest lobbying creates a prisoner's-dilemma-like outcome where each group wants privileges for itself while opposing privileges for others, reducing welfare overall. Economists should continue factual analysis of policy consequences, but should present recommendations in terms of the audience's own interests rather than abstract appeals to social welfare.

Pivotal Quotes: "we should not talk about normative economics, but should talk about applied economics" — Victor Van Berg: Defines the central thesis of his paper and the interview's main conceptual distinction. "the real contribution economists can make is actually to show to people how they can realize mutual gains" — Victor Van Berg: Describes Buchanan's view of economics and the purpose of constitutional economics. "what you are offering are hypothetical imperatives" — Victor Van Berg: Explains why economic policy advice can remain scientific without making explicit value judgments.

Implications: Listeners should view policy advice as audience-specific and institutional, not as universal welfare claims. For economists and policymakers, the key task is designing rules that align incentives, reduce rent seeking, and make mutual gains politically feasible.
