Greg Mankiw on Government Data Accuracy and Modernization

Antiquated Government Data Systems

• 💡 The current government data systems are described as antiquated, making it difficult to gauge the US economy accurately.
• 📌 Data collected can be significantly different from initial estimates, with revisions occurring months later, questioning the reliability of real-time economic indicators.

The BLS Commissioner Firing

• ⚠️ Greg Mankiw views the firing of the BLS commissioner as a petulant move, not a smart one, despite potential valid complaints about data collection methods.
• 🎯 The claim that government data is rigged is stated as completely wrong, with even the former BLS commissioner appointed by the president disagreeing.
• 🚫 Firing individuals every time data is unfavorable or revised is a dangerous precedent that sets wrong incentives for statistical agencies.

Modernizing Data Collection

• 🚀 Modernizing data systems is an important task, especially with new ways to collect data faster and from different sources.
• 💰 However, modernization efforts are hampered by decreasing funding for statistical agencies, which have been cut over time.
• 🧩 Modernization must be done carefully to ensure new data remains broadly consistent with historical data for proper interpretation.

Alternative Data Sources

• 🔬 Initiatives like the Billion Prices Project track prices on the internet to monitor inflation before official CPI data is released.
• 📊 Data from sources like ADP could potentially be incorporated into unemployment data, offering more timely insights.

Restoring Credibility

• 🗣️ To restore credibility, it's crucial to stop blaming individuals who are not at fault, as there is no evidence of data rigging.
• 🤝 Creating a commission to study the organization of statistical agencies and exploring the combination of private and public sector data could improve accuracy and trust.
• 💰 Increased resources and funding are necessary for statistical agencies to undertake modernization and develop more accurate measures, a step that has been neglected by recent administrations.
