Main takeaways: November

2

Holiday season discounts resulted in steep deflation in November for categories such as televisions (-12.9% MoM), appliances (-6.7%), tablets (-6.2%), toys (-4.5%) and domestic hotels (-4.5%)

While international flights saw a 1.9% MoM increase in November, flights to Europe saw 5.1% deflation driven by double-digit MoM deflation for flights to Madrid’s MAD (-10.3%) and Rome’s FCO (-11.6%)

In a reversal from October’s DPI, several DPI categories show MoM deflation in November as a result of deep discounts from holiday sales over the Thanksgiving holiday

Holiday discounts in 2016 were higher for televisions, tablets, and toys, compared to the holiday season in 2015

Groceries, a category that represents the largest share of consumer spending in the DPI showed 0.5% deflation MoM

Sugar and sweets (-0.6%), flour (-0.6%), fruits and vegetables (-0.6%), and meats (-0.4%) saw the largest MoM deflation, while eggs (1.6%), ice cream (1.2%), and juice (0.7%) saw MoM inflation

In the U.K., the DPI shows the first MoM increase in the price index for computers (1.0%), an increase in the price of groceries (0.5%), and a slowing of deflation for TVs (-0.7%), suggesting that Brexit impacts on durable imports coupled with a strong U.S. dollar could be pushing prices upward

Overall U.S. results signal a slight uptick in inflation, a strong labor market, and a stable housing market:

The U.S. Job Seeking Index finds that online job searches are down sharply YoY for another month in a row, with November searches down -17.5% YoY, suggesting continued strength in the U.S. labor market, though momentum maybe slowing

Our U.S. Digital Housing Index an increase of 11.5% YoY in online housing searches. While a strong increase over the prior year, November’s rise is the the second lowest YoY increase over the past 6 months

Adobe DPI in the United Kingdom

8

• Our Digital Price Index in the U.K. for groceries shows that grocery prices have deflated by 1.6% YoY in October. Prices increased 0.5% between October and November, the largest MoM increase in food prices in the U.K over the past 12 months

• For computers, the DPI reveals a YoY deflation of 8.9% while MoMprices increased by 1.0%, the first time in the past 12 months that prices have increased MoM

• Similarly TV prices in the UK continue to fall YoY; the DPI shows YoY deflation of 19.3% between November 2015 to November 2016. Prices are declining slower this month (down 0.7% in November) than they were between September and October (down 1.7%) suggesting that Brexit impacts on durables imports might be beginning to put upward pressure on prices

Inflation rates by price ranges

11

• Televisions have seen higher-ticket items deflate faster than lower-ticket items

• In computers, models priced above $1,200 showing the least deflation in the category

*Price bins are determined based on the price the product had when originally launched (first price).

The Importance of detail: Black Friday

12

• DPI captures the effect of major discount holidays like Black Friday and Cyber Monday because it measures quantities and does so in real-time

• Lowest prices for TVs in 2015 & 2016 were Thanksgiving and Black Friday

• Data demonstrates retailers trying to start sales earlier – the Sunday and Monday before Thanksgiving see low prices

• The Fisher Ideal Price Index uses quantities purchased on the current period (month) and a previous period (previous month) to determine actual consumer’s preferences. Instead of assuming that consumers preferences for what goods to buy are constant over a certain number of years, it is able to account for the fact that they are constantly changing what they buy.
