First-Quarter Seasonal Chicanery

Leftists look for a copout instead of admitting their self-inflicted causes.

In just six weeks, economists, analysts and the business press have become obsessed with “residual seasonality.”

You see, they’re all getting tired of telling us how awful the economy’s performance has been during so many of the year-opening quarters during President Barack Obama’s administration. Friday’s announcement that first-quarter Gross Domestic Product contracted by an annualized 0.7 percent marked the third time since the recession officially ended in mid-2009 that the economy has begun the year with a downturn. Since the remaining quarters have shown better results, they’re all too eager to latch onto any hint that there might be something wrong with the government’s reporting. Enter “residual seasonality.”

All of this appears to have started when CNBC’s Steve Leisman published “Why is the economy always so weak in the first quarter? Nobody Really Knows” on April 22.

I didn’t take Liesman’s column seriously. It’s hard to feel guilty about that. He’s not a serious commentator.

The Keynesian koolaid-drinking Liesman, whose name I consider eponymous, has two primary missions at CNBC: first, to claim that all is well no matter how weak the economy is; and second, to rudely interrupt, shout down and otherwise bully the eminently sensible Rick Santelli when he dares to insert actual facts and historical perspectives into discussions.

Leisman accurately but disingenuously informed readers that first-quarter GDP growth during the past 30 years has averaged 1.87 percent, while the full-year average during that time has been 2.7 percent. After he found “several economists” who characterized that difference as “statisticially significant,” he went into “we’ve got to fix this” mode (the quote is from the story’s accompanying two-minute video, as the text dispatch has since been updated):

… such large differences, they shouldn’t appear if the data was correctly adjusted for seasonality … given the failure of the data to correct itself over time, the government should be involved in trying to correct it. But the Bureau of Economic Analysis, they do the GDP work for the government, they declined to comment.

The BEA, suspiciously moving at warp speed instead of the speed of government, almost instantly broke its silence after the CNBC report appeared. In Liesman’s revised writeup, we see that its spokesman even said that they were already working on the alleged problem:

Brent Moulton, associate director for national economic accounts, said even though the data is adjusted for seasonal patterns, it can still show so-called “residual seasonality.”

“BEA is currently examining possible residual seasonality in several series, which may lead to improvements in …. the regular annual revision to GDP scheduled for July,” he added.

How convenient. Excuse me for believing that someone inside the government who wishes to massage the historical GDP results, scheduled for retroactive revision on July 30, might have planted the idea with Liesman to give the issue, which BEA has clumsily admitted it was already “examining,” a veneer of outside respectability before publicly recognizing it.

Where is this “residual seasonality,” defined as ”the manifestation of seasonal patterns in data that have already been seasonally adjusted,” hiding?

An economics letter published by the Federal Reserve in San Francisco in mid-May contended that there’s evidence of it in “all of the major components of GDP—consumption, business investment, net exports, government spending, and inventory investment.” The authors believe that the first quarter’s originally reported annualized 0.2 percent growth should have come in 1.6 percentage points higher.

Shortly after the San Fran Fed’s letter, the BEA, without quantifying, published two blog posts indicating that its scope might be far narrower. On May 20, it said that it was investigating potential residual seasonality in government defense services spending and certain items in the Census Bureau’s quarterly services survey. On May 22, it added “certain inventory investment series that currently aren’t seasonally adjusted.”

Demonstrating that the problem’s existence is not a given, a May 14 research paper from the Fed in Washington declared that it could not find “convincing evidence of material residual seasonality in GDP in recent years.”

Residual seasonality’s unconfirmed existence hasn’t stopped it from becoming the excuse du jour in the business press. The Associated Press, Bloomberg and Reuters all included it in their roster of potential rationalizations for Friday’s reported contraction. Bloomberg went so far as to claim that it “probably distorted the data.”

Spin doctors posing as financial experts are piling on. Joe LaVorgna, described by the contrarians at Zero Hedge as “Wall Street’s best paid, yet worst weatherman,” claimed after Friday’s reported contraction that a properly presented first quarter would show annualized growth of 1.2 percent.

Given all the hype and hoopla, it’s amazing how easy it was to deconstruct this nonsense.

All that was necessary, for reasons which will soon become quite obvious, was to group the yearly results into four ranges:

Looking at each range presented:

  • 1985 to 1992 contained virtually no net variance between first-quarter and full-year results. There was no reason for Liesman to have included these years in his analysis. He appears to have done so purely to distract.
  • From 1993 to 2000, first-quarter versus full-year variances netting out to 10.6 points were significant, amounting to about 40 percent of the total of 24.4 points seen during the entire period.
  • From 2001 to 2007, the variances once again netted out to nearly nothing.
  • Finally, from 2008 to 2014, the net variances involved totaled a whopping 12.9 points — over half of the total.

How can it be that virtually no net variances between first-quarter and full-year results occurred in the red-labeled ranges, while large variances occurred in the blue ones?

The red ranges represent the years during which Republicans held the presidency and during which their economic and philosophies dominated government operations and economic policy discussions. The blue ranges are the years when Democrats held the White House or held philosophical sway. I assigned 2008 to the Democrats because the economy’s Keynesian calamity began with George W. Bush’s decision to enact a then-seen as significant $170 billion stimulus package early that year.

Contrary to what Steve Liesman claims, the economy isn’t “always so weak in the first quarter.” It’s only weak when we have Democratic Party presidents or when Keynesian “thought,” to use the term very loosely, dominates.

Why is that? That’s easy:

  • Far more than Republicans, Democratic administrations have imposed new taxes. These have largely gone into effect at the beginning of each calendar year, dampening first-quarter economic activity
  • Far more than Republicans, Democratic administrations have imposed new regulations on businesses, entrepreneurs and investors. These have also largely taken effect at the beginning of each calendar year, also impeding economic activity.

In subsequent quarters, the economy adjusts. But as we have seen in recent years, the adjustments have usually been to a level of unprecedented mediocrity.

A longtime commenter at my home blog coined the term for results like these many years ago: ”The Democrat Effect.” Adapted to the current analysis, it is “the rational response by entrepreneurs, businesspeople, and investors to excessive government intervention, overbearing regulation, crippling litigation, and taxation, all of which seriously curtail first-quarter economic activity to a greater extent than initially estimated.”

Those making noise about residual seasonality are trying to falsely “seasonalize” away the visible results of the left’s misguided policies, particularly those of President Obama, his White House, and his regulatory apparatus.

In the name of reporting results with integrity, the BEA must leave things alone.
