Ep76 “How Should You Deal with Uncertainty in Today's World?” with Nick Bloom
TL;DR
Stanford economist Nick Bloom explains the growing divergence between text-based uncertainty measures (newspapers) and market-based metrics (VIX), arguing that while media negativity has hit 200-year highs, actual economic uncertainty likely sits at a moderate 7/10—high enough to freeze hiring but not as extreme as headlines suggest.
📊 Three Lenses for Measuring Uncertainty 3 insights
GDP volatility tracks historical swings
Traditional measures use historical GDP volatility to assess economic stability, but these look backward and miss long-term structural questions like AI's impact over the next decade.
VIX provides real-time market expectations
The VIX index uses option prices to measure implied stock market volatility, averaging 18% annually but spiking to 60-70% during crises like COVID while remaining available instantaneously unlike lagging GDP data.
Text-based indices quantify media sentiment
Bloom's Economic Policy Uncertainty indices scrape thousands of newspapers to count words like 'uncertainty' near policy terms, offering a daily real-time measure of narrative-driven anxiety.
📉📈 The Great Divergence 3 insights
Text and market measures have decoupled sharply
Since 2017 and particularly during 'Trump 2,' text-based uncertainty indices have exploded to 2-3x historical levels while the VIX and business surveys remain near average levels of 5/10.
National versus local media tell different stories
While major national newspapers (New York Times, Wall Street Journal) show extreme uncertainty spikes, an index of 2,000 local newspapers focused on business conditions shows significantly less volatility.
Market composition creates blind spots
Stock markets overweight tech and finance while underweighting manufacturing, agriculture and retail, causing them to miss structural shifts that affect Main Street but not necessarily quarterly earnings.
🔍 Why Markets Ignore Certain Risks 3 insights
Markets overweight bad news
Financial volatility spikes exclusively around negative events like wars or assassinations while ignoring positive long-term developments such as the fall of the Berlin Wall, creating an asymmetric sensitivity.
Media negativity hits 200-year highs
Sentiment analysis reveals news reporting has grown steadily more negative since 1970, reaching the most negative levels since 1850 by 2020 due to 'if it bleeds it reads' editorial incentives.
Text captures long-term political uncertainty
Newspaper measures pick up slow-burning risks like NATO instability, trade arrangement changes and immigration policy that threaten long-run growth but don't immediately impact next quarter's earnings.
💼 Real Economic Consequences 2 insights
Perception drives business decisions
US hiring rates have fallen to 10-year lows as decision-makers react to elevated media uncertainty regardless of market calm, proving that perceived uncertainty matters more than objective 'ground truth.'
True uncertainty sits between extremes
Bloom estimates actual uncertainty at 7/10—significantly higher than markets suggest but lower than national headlines indicate—sufficient to cause business nervousness and investment delays.
Bottom Line
When uncertainty measures conflict dramatically, assume moderate-to-high risk (7/10) and prepare for conservative business behavior like hiring freezes and delayed investments, regardless of whether markets appear calm.
