Poor Charlie's Almanack: The Essential Wit and Wisdom of Charles T. Munger · chapter 2

Academic Economics: Strengths and Faults

Munger argued in 2003 that economics was broken by physics envy and willful blindness to psychology. Three Nobel Prizes (Kahneman 2002, Fama/Shiller 2013, Thaler 2017) and the 2008 crisis proved him substantially right. His investment examples check out against SEC filings. The weak point: his implicit claim that skilled investors can routinely exploit inefficiencies is contradicted by the SPIVA data showing 90%+ failure rate among professionals.

So what

Munger’s 2003 critique of academic economics was ahead of its time and has been largely vindicated by the 2008 crisis, Paul Romer’s ‘pseudoscience’ indictment, and the behavioral economics Nobel prizes. His investment examples (See’s, Coca-Cola) are verified by SEC filings. But the SPIVA data creates a paradox: if Munger is right that markets are exploitable, why do 90% of professionals fail? The answer he gives – that most lack interdisciplinary thinking – is unfalsifiable.

Verdict

MostlyAccurate

Claims checked in this chapter (10)

needs context✓ verified
The Efficient Market Hypothesis is substantially wrong -- markets exhibit predictable bubbles and mispricings that skilled investors can exploit.
holds✓ verified
Economics suffers from 'physics envy' -- excessive mathematization that obscures rather than illuminates, because human systems are fundamentally different from physical systems.
holds✓ verified
Berkshire bought See's Candies for $25 million in 1972 when it had pre-tax earnings of approximately $4 million, and the investment has generated over $2 billion in cumulative pre-tax profits.
holds✓ verified
Coca-Cola has been a paradigm investment -- Berkshire invested approximately $1.3 billion starting in 1988 and the position generates annual dividends exceeding 56% of the original cost basis.
holds✓ verified
Munger argues that the Capital Asset Pricing Model (CAPM) and beta as a risk measure are fundamentally flawed because volatility does not equal risk.
holds✓ verified
Munger critiques the 'rational agent' assumption in economics, arguing that real humans are predictably irrational and economics must incorporate psychology to be useful.
holds✓ verified
Munger argues that 'man with a hammer syndrome' -- using a single tool for every problem -- is a major cause of professional failure, particularly in academia where disciplines remain siloed.
holds✓ verified
Munger argues the Efficient Market Hypothesis is approximately right for most participants but pockets of inefficiency exist that skilled investors can exploit.
needs context✓ verified
Munger claims economics departments fail students by not teaching enough psychology, leading to flawed models of human behavior.
holds✓ verified
Munger uses the Coca-Cola case study to argue that franchise businesses with strong consumer brands possess 'moats' that justify paying premium valuations, contradicting Graham's strict emphasis on buying below book value.
