Through clear explanations and insightful analysis, this episode equips listeners with a deeper understanding of how these statistics shape economic decisions and influence global markets.
Introduction to Economic Statistics
Gary Arndt opens the discussion by emphasizing the pivotal role that economic statistics play in both public and private sectors. He highlights how these metrics influence billions of dollars in investments and inform critical economic policies.
"Trillions of dollars globally are spent and invested on the basis of this data."

Gross Domestic Product (GDP)
Definition and Calculation Methods
Gary delves into GDP as the most widely recognized measure of economic activity. He explains the two primary methods of calculating GDP:
-
Expenditure Approach:
GDP = Consumer Spending + Business Investment + Government Spending + (Exports - Imports)"GDP equals total consumer spending plus total business investment plus total government spending plus the difference between exports minus imports."
(Host, 03:10) -
Income Approach:
GDP = Wages + Rents + Interests + Profits + Taxes"GDP equals wages plus rents plus interests plus profits plus taxes."
(Host, 03:25)
GDP vs. GNP
Gary distinguishes GDP from Gross National Product (GNP), noting that GDP focuses on economic activity within a country's borders, while GNP accounts for the production by a country's residents globally.
"GDP measures the total value of goods and services produced within a country's borders, while GNP includes the value of goods and services produced by a country's residents, regardless of whether the production occurs domestically or abroad."
(Host, 04:00)
Nominal vs. Real GDP
He further differentiates between nominal GDP, which uses current prices, and real GDP, which adjusts for inflation to reflect true economic growth over time.
"Nominal GDP measures the total value of goods and services using current prices, while real GDP adjusts for inflation to reflect the true value of economic output over time."
(Host, 04:30)
Limitations of GDP
Gary critiques GDP by pointing out its inability to capture informal or black market activities, which can constitute a significant portion of the economy in developing countries.
"GDP does not measure informal or black market activity... in some developing countries as high as 25 to 40% of GDP."
(Host, 05:15)
He also notes that GDP might include spending that doesn't necessarily improve living standards, such as disaster recovery or large infrastructure projects funded by foreign debt.
Unemployment Rate
Understanding the Unemployment Rate
Gary breaks down the unemployment rate, clarifying that it represents the percentage of the labor force that is unemployed and actively seeking work.
"The unemployment rate is calculated as the number of unemployed people divided by the total labor force multiplied by 100 to make it a percent."
(Host, 07:20)
Challenges in Measurement
He discusses the complexities involved in accurately measuring unemployment, highlighting issues such as "discouraged workers" who have stopped seeking employment and thus are not counted in the statistics.
"The higher the unemployment rate is, the greater the odds that it's actually under reporting because it doesn't count discouraged workers."
(Host, 08:00)
Gary also mentions that full employment isn't synonymous with 0% unemployment, with most economists estimating full employment at around 4 to 5%.
"Most economists would put full employment at around 4 to 5%."
(Host, 08:45)
Inflation and the Consumer Price Index (CPI)
Measuring Inflation with CPI
Inflation, a crucial economic indicator, is traditionally measured using the Consumer Price Index (CPI). Gary explains how CPI tracks the change in prices of a fixed basket of goods over time.
"The CPI is the change in the price of a basket of goods that is tracked as a proxy for the overall economy."
(Host, 10:10)
Problems with CPI
However, Gary outlines several limitations of CPI:
-
Representativeness of the Basket:
It's challenging to ensure that the basket of goods accurately reflects consumer spending patterns. -
Frequent Adjustments:
With around 30 changes to the CPI in the last 20 years and six major methodological shifts since 1919, historical comparisons can be unreliable."Since 1919, when it was first calculated, there have been no fewer than six major changes to how the CPI is calculated and weighed."
(Host, 11:30) -
Technological Advancements:
Rapid improvements in technology make it difficult to compare prices over time meaningfully."How do you compare a modern computer with something that's decades old?"
(Host, 12:15) -
Substitution Bias:
When prices of certain goods rise, consumers may switch to cheaper alternatives, affecting the accuracy of CPI. -
Housing Costs Measurement:
Instead of actual rent or mortgage payments, CPI uses "owner’s equivalent rent," which may not accurately reflect housing expenses."The CPI doesn't actually measure rent directly... it measures owner's equivalent rent."
(Host, 14:00)
Potential for Manipulation
Gary warns that the opacity of CPI makes it susceptible to manipulation, with governments potentially adjusting the basket to present a more favorable economic picture.
"Because the CPI is so opaque compared to other economic statistics, it's more prone to manipulation."
(Host, 15:20)
Money Supply as an Alternative Measure
Understanding M1 and M2
As alternatives to CPI, Gary introduces the concept of money supply metrics:
-
M1:
Includes all physical money like cash and checking accounts. -
M2:
Encompasses M1 plus savings accounts and short-term time deposits like Certificates of Deposit (CDs).
"M2 is considered a measure of inflation because inflation is usually considered to be a reflection of growth in the money supply."
(Host, 17:45)
Gary suggests that monitoring M2 can provide insights into potential inflationary trends, as an increasing money supply often correlates with rising prices.
Stock Market as an Economic Proxy
Role of Stock Indices
Gary examines the stock market's use as an economic indicator, focusing on various indices:
-
Dow Jones Industrial Average (DJIA):
Comprises 30 large, publicly-owned companies based in the United States. -
Standard and Poor's 500 (S&P 500), NASDAQ Composite, NASDAQ 100, Russell 500, Wilshire 5000:
Broader indices that include a more extensive range of companies, offering a more accurate reflection of the overall economy.
"The broader the index with more stocks, the more accurately it represents the state of the economy."
(Host, 20:30)
Limitations of Stock Indices
Gary points out that smaller indices like the DJIA may not fully capture economic realities since they represent only a subset of the market.
"The Dow Jones is nothing more than a collection of 30 popular and successful stocks... it's just 30 stocks."
(Host, 21:15)
He also highlights that stock indices are not adjusted for inflation, necessitating manual adjustments for accurate long-term comparisons.
Impact of Index Funds
The rise of index funds has introduced artificial demand for stocks included in indices, potentially skewing their performance and not necessarily reflecting underlying economic conditions.
"Any stock that's listed on an index will have, at least at some level, some artificial demand for the stock compared to other stocks that are not in the index."
(Host, 22:50)
Manipulation of Economic Data
Gary underscores the potential for governments to manipulate economic statistics for propaganda or political gains, citing historical examples like the Soviet Union's fabricated growth rates.
"Even exaggerating growth by 1% every year will have compounding effects over just a few years that will make the economy out to be something that it isn't."
(Host, 24:10)
He warns that such manipulations can distort economic perceptions and lead to misguided policies and investments.
Conclusion
In wrapping up, Gary reiterates the importance of understanding the definitions, calculations, and limitations of economic statistics. He urges listeners to approach these metrics with a critical eye to make informed decisions.
"Economic statistics are very important... it's just important to know what they are, what they're actually measuring, and what their potential flaws are."
(Host, 25:50)
