How to Make Better Economic Policy Choices

Dec 21, 2020 Mariana Mazzucato , Simon Sharpe

While public policy organizations are increasingly diversifying their decision-making approaches, many remain overly reliant on static tools such as cost-benefit analysis. Such tools have severe limitations, leading to policy errors with serious long-term consequences.

LONDON– The United Kingdom is entering its deepest recession in 300 years. Millions of jobs are at risk. And national debt has exceeded 100% of GDP. Now is hardly the time to explore the conceptual underpinnings of economic theory, right?

In fact, as governments everywhere are borrowing, spending, and regulating on an unprecedented scale, a deeper understanding of economic decision-making is essential both to accelerate the recovery and to avoid longer-term risks. That is why the UK Treasury’s new guidance on decision-making for transformational change is so welcome, and why finance ministries everywhere should follow suit.

In a recent study for the UK’s Better Regulation Executive, we found that, while public policy organizations are increasingly diversifying their approaches to decision-making, many remain overly reliant on static tools such as cost-benefit analysis. Such tools are ill-suited to understanding, predicting, and driving innovation and structural change in the economy.

Cost-benefit analysis is not static; however, some unscrupulous users might choose to cite such an analysis in announcing a public policy decision. The late British economist Alan Williams argued compellingly in an illuminating 1972 article entitled "Cost-Benefit Analysis: Bastard Science? And/Or Insidious Poison in the Body Politick?", that CBA seeks to assist policy makers, but not replace them, in making effective judgments by explicitly presenting key assumptions, identifying all relevant evidence, and communicating the resulting judgments in a way that can be replicated. American economist Victor Fuchs made a similar argument in his 1980 article entitled "What Is CBA/CEA And Why Are They Doing This To Us?" Both Williams and Fuchs sought to make decision-makers both transparent in the tradeoffs they make in their analyses and accountable for the results.

While all the excessive exposures that could bring down bank systems are built-up with assets perceived as safe, few things more static than the risk weighted bank capital requirements based on how credit risks are perceived risky, at this moment.
