Ep76 “How Should You Deal with Uncertainty in Today's World?” with Nick Bloom

Key Concepts

• Uncertainty Measures: Quantitative methods to assess economic instability, categorized into financial market data (e.g., VIX), text-based analysis (NLP of news), and surveys.
• Real Options Theory: A framework explaining that when uncertainty increases, the "option to wait" becomes more valuable, leading firms to delay investment and hiring.
• VIX (Volatility Index): A forward-looking measure of stock market volatility derived from option prices, representing market expectations of future economic activity.
• Economic Policy Uncertainty (EPU) Index: A metric developed by Nick Bloom and Steve Davis that uses text-scraping of newspapers to quantify uncertainty related to policy and economic events.
• Mean Reversion: The tendency of economic variables to return to their long-term average after a shock.
• "If it bleeds, it reads": A media industry adage suggesting that negative news generates higher engagement, potentially skewing public perception of uncertainty.

1. Measuring Uncertainty: Methods and Discrepancies

The podcast identifies three primary ways to measure uncertainty:

• Financial Markets: Uses option prices (VIX) to gauge forward-looking volatility. It is real-time but often biased toward sectors like tech and finance and tends to over-react to negative news while ignoring positive structural changes (e.g., the fall of the Berlin Wall).
• Text-Based Analysis: Scrapes news outlets for keywords related to uncertainty. Recent data shows a massive divergence: while market volatility remains moderate, text-based indices have spiked to 2–3 times their historical levels.
• Surveys: Direct inquiries to business leaders regarding their outlook.

The "Conundrum": A significant divergence has emerged in the last 18 months. Text-based measures suggest "10 out of 10" uncertainty, while markets and surveys suggest "5 out of 10." Professor Nick Bloom suggests the truth lies in the middle, noting that mainstream media may be over-indexing on political drama (e.g., "Trump Derangement Syndrome"), whereas local newspapers—which focus on regional business—show much lower levels of uncertainty.

2. Real-World Applications and Case Studies

• Brexit: Cited as a prime example of "persistent uncertainty." Unlike short-term shocks that cause sharp, temporary dips, the decade-long uncertainty surrounding Brexit resulted in a permanent reduction in UK GDP by approximately 6%.
• The "Greenspan Put" / Policy Intervention: The hosts discuss the theory that markets may be less volatile because investors expect government intervention (e.g., the "Trump put") to stabilize the economy during crises, effectively suppressing market-based volatility signals.
• Labor Markets: Current hiring rates are at a 10-year low (excluding the 2020 pandemic drop). This is attributed to a combination of AI-related disruption and geopolitical uncertainty (e.g., Iran, energy prices).

3. Methodologies: The Text-Based Approach

Professor Bloom explains the evolution of his EPU index:

• Data Sources: Scrapes leading national newspapers (e.g., WSJ, NYT) and specialized reports like the Economist Intelligence Unit (EIU) country reports.
• Refinement: By comparing national papers with 2,000 local newspapers, researchers can filter out "chattering class" noise to see if uncertainty is truly pervasive or merely a media-driven narrative.
• Sentiment Analysis: Research indicates a steady, unprecedented decline in the positivity of news reporting since 1970, suggesting that the competitive, ad-driven nature of modern media incentivizes increasingly negative coverage.

4. Key Arguments and Perspectives

• The "Chicken Little" Effect: The media’s tendency to sensationalize bad news can create a "paranoid state" among decision-makers, which then becomes a self-fulfilling prophecy by causing firms to pause hiring and investment.
• The Role of AI and Politics: Unlike past shocks, current uncertainty is driven by structural shifts—AI and political polarization—which are likely to be persistent rather than transitory.
• Policy Stability: Bloom argues that politicians should "tie their hands" by supporting independent central banks and stable, predictable budget processes to minimize their own role as a source of economic volatility.

5. Actionable Insights for Business Leaders

Professor Bloom recommends three strategies for navigating high-uncertainty environments:

1. Prioritize Flexibility: Favor renting/leasing over buying/owning to maintain the ability to pivot.
2. Monitor Politics: Acknowledge that "the business of business" now includes navigating political landscapes; firms should invest in political intelligence and lobbying.
3. Contingency Planning: Develop "fleet-of-foot" plans that allow for rapid responses to unexpected shocks, even if the specific scenario (e.g., a pandemic or outage) is not perfectly predicted.

Synthesis

The core takeaway is that uncertainty is no longer a simple, singular metric. While financial markets provide a "market-clearing" view of risk, text-based indices capture the psychological and political climate. Business leaders must distinguish between "noise" (media-driven negativity) and "signal" (structural shifts like AI and geopolitical instability). Because current drivers of uncertainty are persistent, firms must shift from a "wait-and-see" approach to one defined by structural flexibility and proactive contingency planning.
