The beginning of the US economy’s second year under the Tax Cuts and Jobs Act was largely positive, though some troubling signs lurked just beneath the good news.

The government’s initial estimate of first quarter Gross Domestic Product (GDP) reported a surprisingly strong annualized growth rate of 3.2 percent, up from 2.2 percent in the fourth quarter of 2018 and a solid improvement from the 2.1 percent pace of a year ago.

The major reasons for the quarter’s strong growth: a burst in exports, a decline in imports, and a rise in inventories that, combined, accounted for about half of the economy’s first quarter growth. It is hard to attribute any of those factors to tax cuts. And they likely are temporary factors that could well reverse in coming months.

Increased state and local government spending also contributed to a significant chunk of growth. Personal spending, the biggest driver of the US economy, rose at an annual rate of only 1.2 percent as households purchased more services and consumer goods but spent less on durable goods such as large appliances. It at least makes one wonder whether the Keynesian stimulus of the TCJA is fading.  

While workers and others may not have been spending robustly, the labor market remained strong.  Except for a weak February, job creation so far this calendar year has been solid, up an average of about 193,000 through April. That, however, is roughly the same as the pre-TCJA levels of 2016 and 2017, and down somewhat from the monthly average of 227,000 last year.  

Wage growth remains modest. The Federal Reserve Board of Atlanta’s three-month moving average of   median wage growth has shown little change since 2017.

Capital spending as measured by non-residential fixed investment grew at an annual rate of 2.7 percent in the first quarter, well below the pace of the first half of 2018—the period right after passage of the TCJA. 

The growing economy and low inflation, combined with the Federal Reserve’s decision to hold short-term interest rates steady, has resulted in continuing growth in equity values. Only President Trump’s on-again, off-again, threats of renewed trade wars with China and Europe seem to slow the steady upward movement of the stock market

The state of federal finances continued to deteriorate, a surprise to few outside the White House given the $1.5 trillion loss in federal revenues due to the TCJA and higher federal spending.

In the first three months of 2019, the Treasury collected about $351 billion in individual income taxes and about $17 billion in corporate income taxes. In the same period in 2017, before the TCJA passed but when the economy was smaller, Treasury collected about $342 billion in individual income taxes and $24 billion in corporate income taxes.  Overall, Treasury collected roughly the same $730 billion in the first three months of 2019 as it did in same period of 2017. Federal spending, by contrast, continues to grow, up from $4.1 trillion in fiscal year 2018 to $4.5 trillion in fiscal 2019.

Despite growing deficits—likely to top $900 billion this year—Treasury bond prices remain high and yields low.

In sum, the post-TCJA economy remains healthy, essentially continuing the recovery that began after the economy bottomed out during the Great Recession a decade ago. But despite last quarter’s strong results, the economy may be returning to pre-TCJA growth rates following 2018’s Keynesian bump.
