Economic Impacts Of Falling Energy Costs

"If you repeat a falsehood long enough, it will eventually be accepted as fact."

In the financial markets and economics it is a common occurrence that the media and commentators will latch on to a statement that supports a cognitive bias and then repeat that statement until it is a universally accepted truth.

When such a statement becomes universally accepted and unquestioned, well, that is when I begin to question it.

One of those statements has been in regards to plunging oil prices. The majority of analysts and economists have been ratcheting up expectations for the economy and the markets on the back of lower energy costs. The argument is that lower oil prices lead to lower gasoline prices that give consumers more money to spend. The argument seems to be entirely logical since we know that roughly 80% of households in America effectively live paycheck-to-paycheck meaning they will spend, rather than save, any extra disposable income.

As an example, Steve LeVine recently wrote:

"US gasoline prices have dropped for more than 90 straight days. They now average $2.28 a gallon, which is remarkable considering that just a few months ago, some of us were routinely paying $4 and sometimes close to $5. Not so coincidentally, the US economy surged by 5% last quarter, and does not appear to be slowing down. "

If you read the statement, how could one possibly disagree with such a premise? If I spend less money at the gas pump, I obviously have more money to spend elsewhere. Right?

The problem is that the economy is a ZERO-SUM game and gasoline prices are an excellent example of the mainstream fallacy of lower oil prices.

Example:

  • Gasoline Prices Fall By $1.00 Per Gallon
  • Consumer Fills Up A 16 Gallon Tank Saving $16 (+16)
  • Gas Station Revenue Falls By $16 For The Transaction (-16)
  • End Economic Result = $0

Now, the argument is that the $16 saved by the consumer will be spent elsewhere. This is the equivalent of "rearranging deck chairs on the Titanic."

Increased consumer spending is a function of increases in INCOME, not SAVINGS. Consumers only have a finite amount of money to spend. Let's use another example:

Example:

Big John Has $100 To Spend Each Week On Retail Related Purchases

  • Big John Fills Up His Truck For $60 (Used To Cost $80) (+$20)
  • Big John Spends His Normal $20 Per Week On His Favorite Craft Beer
  • Big John Then Spends His Additional $20 Savings On Roses For His Wife (He Makes A Smart Investment)

-------------------------------------------------
Total Spending For The Week = $100

Now, economists quickly jump on the idea that because he spent $20 on roses, there has been an additional boost to the economy. However, this is false. John may have spent his money differently this past week but here is the net effect on the economy.

Gasoline Station Revenue = (-$20)
Flower Show Revenue = +$20
----------------------------------------------------
Net Effect To Economy = $0

Graphically, we can show this by analyzing real (inflation adjusted) gasoline prices compared to retail "control purchases." I am using "control purchases" as it removes retail gasoline sales, automobiles, and building materials from the retail sales number to focus more on what consumers are buying on a regular basis.
