Understanding Value Judgment in Welfare Economics

When economists debate what’s best for society, they aren’t just crunching numbers or analyzing data. Behind every policy recommendation, every statement about social welfare, lies something deeper and more personal: a value judgment. These are the ethical beliefs that shape how we think about what’s good or bad for society, and they’re fundamental to the entire field of welfare economics.

What are value judgments? 🔗

Value judgments are ethical beliefs about what is good or bad that aren’t based on scientific logic or laws. Unlike empirical facts that can be tested and verified, value judgments spring from our ethical, political, philosophical, or religious convictions. They’re the lens through which we view what’s desirable for societal well-being.

Think about it this way: when you believe that reducing poverty is good for society, or that everyone deserves equal opportunities, you’re making a value judgment. These aren’t statements you can prove in a laboratory or deduce from mathematical equations. They’re normative claims about how the world ought to be, not positive descriptions of how it is.

Why value judgments matter in welfare economics 🔗

Here’s the thing about welfare economics: it’s inherently an ethical enterprise. The moment we talk about social welfare, we’re stepping into the territory of what’s good for people and society. Any policy prescription or economic theorem about improving welfare automatically carries with it certain assumptions about what constitutes a better state of affairs.

Consider a simple example: Should the government tax wealthy citizens to provide healthcare for the poor? Your answer depends entirely on your value judgments about fairness, individual rights, and social responsibility. Do you value equality of outcomes? Personal property rights? The greatest good for the greatest number? These underlying beliefs shape economic recommendations in ways that pure data analysis never could.

The inevitable ethical dimension 🔗

Modern economists have largely accepted that welfare economics cannot be separated from value judgments because any statement about increasing or decreasing social welfare necessarily involves ethical positions. Unlike studying how markets work or how prices are determined, welfare analysis requires us to make normative claims about what’s desirable.

The great value judgment debate 🔗

Not everyone has always been comfortable with this reality. In the 1930s, economist Lionel Robbins launched a powerful critique, arguing that value judgments were fundamentally unscientific. Robbins believed that if economics was to be an objective, scientific study, economists should refrain from making interpersonal comparisons or ethical recommendations. After all, how can you scientifically prove that one person’s happiness is more important than another’s?

The rise of “value-free” economics 🔗

In response to Robbins’ criticism, economists Nicholas Kaldor and John Hicks attempted something ambitious: creating a welfare economics free from value judgments. Their solution was the compensation principle, which formed the foundation of New Welfare Economics.

The compensation principle works like this: if those who gain from a policy change could theoretically compensate those who lose and still be better off, then the change increases social welfare. Notice the clever move here-by focusing on potential compensation rather than actual distribution, Kaldor and Hicks thought they could avoid making value judgments about whose welfare matters more.

But critics weren’t convinced. As it turns out, even the compensation principle smuggles in hidden value judgments, particularly the assumption that potential gains can be meaningfully compared using monetary values.

Bergson’s solution: embracing explicit value judgments 🔗

Enter Abram Bergson with a radically different approach. Rather than trying to eliminate value judgments, why not acknowledge them openly and work with them systematically? In his groundbreaking 1938 article, Bergson introduced the concept of the social welfare function-a mathematical framework that formally incorporates value judgments into welfare analysis.

Bergson’s insight was brilliant in its simplicity: instead of pretending value judgments don’t exist, make them explicit. This way, economists can systematically trace the implications of any set of ethical assumptions within a rigorous scientific framework. You start with a clear statement of your values, then use economic analysis to determine what policies would promote those values.

The scientific approach to ethics 🔗

What makes Bergson’s approach scientific isn’t the absence of value judgments but the transparency and logical consistency with which they’re used. As Professor Baumol noted, to decide whether one economic state is better than another, we must employ value judgments. The key is making those judgments explicit rather than hiding them behind supposedly neutral criteria.

Common value judgments in welfare studies 🔗

While value judgments vary across cultures and individuals, welfare economists have identified several that appear frequently in economic analysis. These common assumptions help create a shared foundation for policy discussions.

Consumer sovereignty 🔗

This principle holds that individuals are the best judges of their own welfare, and their preferences should count in determining social welfare. When you choose chocolate over vanilla ice cream, that choice reveals something meaningful about your wellbeing. The economy should respond to these individual preferences rather than imposing what a paternalistic authority thinks is good for people.

Equal consideration 🔗

Many welfare analyses assume that each person’s welfare should be given equal weight when calculating social welfare. A gain in happiness for one person matters just as much as an identical gain for anyone else, regardless of their income, social status, or other characteristics. This seemingly simple assumption has profound implications for how we think about distributing resources.

The Pareto principle 🔗

Perhaps the most widely accepted value judgment in welfare economics is the Pareto principle: if a change makes at least one person better off without making anyone worse off, then social welfare has increased. This principle is attractive because it seems minimally controversial-surely we can all agree that win-win situations are good?

Yet even this apparently neutral criterion embodies value judgments. It assumes that individual welfare is what matters, that we can trust people’s own assessments of their wellbeing, and that improving someone’s situation without harming others is inherently valuable. These may seem obvious, but they’re not universal truths-they’re ethical positions.

The path forward: honest economics 🔗

Today’s consensus among welfare economists is clear: value judgments are unavoidable, but that doesn’t make welfare economics unscientific. What matters is being honest about our ethical assumptions and rigorous in tracing their logical implications.

When an economist recommends a policy to reduce inequality, they should acknowledge the value judgment that equality matters. When someone argues for efficiency over equity, they should recognize they’re prioritizing one ethical goal over another. This transparency doesn’t weaken economic analysis; it strengthens it by making clear exactly what assumptions drive our conclusions.

The alternative-pretending economics can be purely objective-only hides value judgments rather than eliminating them. And hidden assumptions are far more dangerous than explicit ones because they can’t be debated, questioned, or refined.

What do you think? Are there certain value judgments about social welfare that seem universally valid to you? Or does acknowledging the role of ethics in economics make you more skeptical of policy recommendations from experts?
