Episode Title: Can We Just Change How We Measure GDP?
Introduction
In this episode of Planet Money, hosts Mary Childs and Nick Fountain delve into the intricacies of Gross Domestic Product (GDP)—a primary indicator of economic health—and explore the contentious proposal to alter its traditional measurement. The episode examines historical challenges, political pressures, and the potential implications of redefining GDP.
Understanding GDP: Definition and Calculation
The episode begins by demystifying GDP, explaining its role as the total tally of all goods and services bought and sold within the economy over a year.
-
Steve Landefeld, former head of the Bureau of Economic Analysis (BEA), defines GDP as:
“[00:03:36] GDP is the statistic that captures all final transactions in the US economy. Buying and selling of goods and services within a one year period.”
The hosts break down the GDP formula, highlighting its components:
- Consumption (C): All goods and services purchased by households.
- Investment (I): Business investments in factories, machinery, and equipment.
- Government Spending (G): Expenditures on public services like schools and roads, excluding government transfers.
- Net Exports (X - M): The difference between exports and imports.
They emphasize the significance of GDP in shaping government budgets, business investments, and presidential evaluations.
The Integrity of GDP Measurements: Steve Landefeld's Perspective
Steve Landefeld discusses his two-decade tenure at the BEA, focusing on maintaining the integrity and accuracy of GDP measurements amidst external pressures.
“[00:05:51] Steve Landefeld: ...he was the defender of GDP's integrity.”
He recounts the constant attempts by various industries to influence GDP figures to present their sectors favorably. Landefeld remained committed to ensuring that GDP accurately reflected economic realities, resisting pressures to inflate sector-specific contributions artificially.
Political Pressures on GDP Calculations: Clinton and Greenspan
The episode explores historical instances where political figures sought to influence GDP metrics:
-
President Bill Clinton's Administration:
-
Proposal to Adjust Real GDP: In the mid-1990s, the BEA, under Landefeld, proposed a more accurate measure of inflation-adjusted GDP. This adjustment aimed to better reflect true economic growth by using improved inflation metrics.
-
Clinton's Reaction: Clinton's administration interpreted these changes as politically damaging, believing they would retrospectively benefit his predecessors and unfavorably impact his own administration's GDP figures.
“[00:07:07] Steve Landefeld: Experts agree it's a much more accurate measure of real GDP growth. But what it's going to do is it's going to raise growth prior to your administration and lower it after you came into office.”
-
Outcome: Despite initial resistance, Landefeld and his team successfully implemented the changes, prioritizing statistical accuracy over political convenience.
-
-
Alan Greenspan's Influence:
-
The Fed Chair's Agenda: Alan Greenspan, chair of the Federal Reserve, pressured the BEA to enhance productivity measurements in the service sector. His goal was to justify maintaining low interest rates by showcasing robust productivity growth.
-
BEA's Response: Landefeld resisted manipulating data but acknowledged that accurate adjustments did find significant productivity improvements.
“[00:13:04] Steve Landefeld: No, no, no, no, no.”
-
Long-term Implications: These adjustments were later scrutinized as factors contributing to the 2008 financial crisis, highlighting the complexities of accurate economic measurements in policy-making.
-
Efforts to Improve GDP: Green Adjusted GDP
Addressing criticisms that GDP overlooks crucial aspects like environmental degradation and unpaid household labor, Landefeld recounts the BEA's attempts to create supplementary measures:
-
Unpaid Household Labor:
-
Advocacy for Inclusion: Groups argued that activities like cooking, cleaning, and child-rearing, predominantly performed by women, significantly contribute to the economy and should be quantified.
-
Challenges: The BEA struggled to incorporate these non-monetary transactions due to the lack of direct financial exchanges, leading to reliance on theoretical estimates.
-
Outcome: Despite recognizing the importance, the BEA did not integrate unpaid labor into GDP, maintaining the focus on transactional economic activities.
-
-
Environmental Impact:
-
Green Adjusted GDP: In the early 1990s, Landefeld spearheaded the development of an environmentally adjusted GDP to account for pollution and resource depletion.
“[00:17:04] Nick Fountain: ... instead of changing GDP, he tried something else.”
-
Political Backlash: The introduction of green GDP faced fierce opposition from congressional representatives of coal-dependent regions, resulting in budget cuts and the eventual discontinuation of the initiative.
“[00:18:09] Mary Childs: Did that surprise you? How did that feel?...”
-
Current Debate: Removing Government Spending from GDP
The central focus of the episode is the Trump administration's proposal, led by Commerce Secretary Howard Lutnick, to exclude government spending from GDP calculations.
-
Technical Feasibility:
-
Simplistic Subtraction: Given that GDP components are already disaggregated, Lutnick could theoretically subtract government spending from the total GDP figure.
“[00:19:38] Steve Landefeld: You subtract line 50 from line one and you got the number he wants.”
-
Creating New Indicators: Instead of altering GDP, Landefeld suggests introducing new metrics that isolate government spending without disrupting the established GDP framework.
“[00:20:21] Nick Fountain: So just make up a new. Not make up, make up a new indicator.”
-
-
Potential Consequences:
-
Erosion of Trust: Altering fundamental GDP calculations undermines the autonomy and objectivity of national statistics, potentially leading to mistrust in economic data.
“[00:21:01] Steve Landefeld: If it were dramatically changed, I'd be very concerned...”
-
Historical Precedence: Landefeld references past attempts to modify GDP for political gains, emphasizing the risks associated with such changes.
-
The Autonomy and Trustworthiness of GDP
Landefeld underscores the importance of GDP's integrity for reliable economic analysis and policymaking. He cautions against politicizing economic metrics, stressing that:
-
Objective Measurements: GDP must remain an unbiased measure to accurately reflect economic health and guide informed decision-making.
-
Potential Catastrophic Impact: Manipulating GDP figures for political advantage could lead to misguided policies and erode public confidence in economic institutions.
Conclusion
The episode concludes with a reinforcement of GDP's critical role in economic assessment and policy formulation. Hosts Mary Childs and Nick Fountain, alongside Steve Landefeld, advocate for maintaining GDP's integrity against political and ideological pressures. The potential alteration of GDP measurement by excluding government spending is portrayed as a dangerous move that could compromise the reliability of one of the most vital economic indicators.
