There are four main components to the Gross Domestic Product: Gross Private Domestic Investments (GPDI,) Personal Consumption Expenditures (PCE,) Imports/Exports, and Government Consumption Expenditures. This column has written an article pointing out that the growth ion retail sales, part of the PCE component, may have been undervalued. Will they be undervalued in the Second Quarter Advance GDP report? It depends how the data is recorded, non-seasonally adjusted, and how it is reported, seasonally adjusted.
The seasonally adjusted quarter to quarter Retail sales grew at 1.8%. Retail sales almost contracted during the second quarter of 2016. Retail sales did contract during the second quarter of 2013. The quarter to quarter growth reflects the "Table 1" headline GDP growth number. Non-seasonally adjusted quarter to quarter growth approached 10% at 9.44%. While this sounds good, it is fairly normal for spikes in sales during June and December. It was better than 2017Q2 Q2Q growth of 8.61 and slightly slower than 2016Q2 when we recorded a NSA growth rate of 9.83%. We were under 7.0% during the second quarter of 2012, 2013, and 2014.
The seasonally adjusted same quarter data spiked by 5.95% This makes sense when you compare the quarter to quarter growth rate of 2017Q2 and 2018Q2. We have recorded record levels of sales for the current month data each of the first six months of this year. This means that January was the best total sales month for the month of January ever. The same was true with the best February total sales, best March total sales, and the best April, May, and June total MARTS retail sales, non-seasonally adjusted.
Gross Private Domestic investment has been up during April and May. The Value in Place Construction data for April was up 7.6% April 2018 versus April 2017. The May to May change was up 4.3%. We do not have the June value at the time of this writing so it is not really possible to calculate the Quarter to Quarter data or the Same Quarter growth. We know that the new construction starts for residential sales is ahead of where we were during the first six months of 2017.
The Import - Export data is incomplete, too. The Census provides information on the import and export of goods and services. This is seasonally adjusted data. First quarter we had exports of $619 billion versus $576 billion 2017Q1. Imports were up from $711 billion to $774 billion. So far imports are up $38 billion 2017Q2 and exports are up $42 billion. Again, this is all seasonally adjusted data, and again we do not have the June data. This net improvement in Q2Q growth should be a positive, or less of a negative, than it was last year.
The Government spent less money second quarter than first quarter. There is no seasonally adjusted data published for this. Outlays 2017Q1 was 1.049 trillion and 2018Q1 (calendar year) was 1.102T. Outlays 2017Q2 was $1.01 trillion and $1.051 trillion 2018Q2. Same quarter data was up 1.97% while Q2Q was down 4.63% This means that there could be a drag on the GDP without seasonally adjusted data.
If personal consumption expenditures are 70% of GDP then that component could add 4% to GDP. The "final" 2018Q1 value was 2.0% growth with 0.6% coming from PCE and 1.22% coming from GPDI. Last year the PCE provided a bump of 2.2% to GDP and GPDI provided 0.64%. If April and May Value in place were both up over last year, and June had better starts data than June 2017 then GPDI should rise. Let's say that we see a 1.5% "spiff" to 2018Q2 data from PCE - that places us well above 4% to nearly 4.5%. Will we exceed the GDP of 2014Q2? The devil is in the seasonal factors.
One more thing. The same quarter GDP, Table 8 data, has been steadily rising for seven consecutive quarters. Last month this value was at 2.8%. We should poke through 3%. That will be better than the second quarter value for 2010, 2012, and 2014, an in fact we are already there as of 2018Q1.
Expect good numbers. Expect revisions as the GPDI and import-export number data is released and revised.
It's the economy.
