Using Game Theory to Optimize the Pace of New Technology Adoption

Innovators of new technology systems requiring users to combine both hardware and software components often face delays in adoption of their new systems.  Users will not buy the hardware until enough software or content is available, while at the same time software providers will not provide content until enough users have adopted the new system.  This book examines the dynamics of this adoption process and provides methods for optimizing the pace of adoption of new technology systems.     Read more...

This brief analysis examines how retail sales have changed over the past 25 years, both in size and distribution.

As seen in Figure 1, total retail sales have grown by 2.7% - 2.8% per year, excluding the short drop in spending during the Financial Crisis (2007 – 2009).

As seen in Figure 2, the top six general categories of retail sales,

  1. Automobiles
  2. Food Stores
  3. Eateries
  4. General Merchandise
  5. Gas stations
  6. E-Commerce

have accounted for about three-quarters of total sales during the period, and they grew slightly as a portion of total sales, 2.2%, from 73.2% in 1992 to 75.4% in 2016.

The big loser was Food Stores, which decreased its share of total retail sales between 1992 and 2016 by 5.7%. Some of that decrease was offset by an increase in share of Eateries, by 1.9%. However, overall, the food and beverage category has taken a smaller share of retail spending in recent than in previous years.

The big winner was – no surprise – E-Commerce. 6.3% more retail sales have been captured by online vendors over the past 25 years. Of course, some (small?) portion of this is for food, which makes up for a bit of the loss in that category.

If we take a closer look at the details (see Figure 3), we see that there has been another shift. Within the General Merchandise category, there has been a shift away from Department Stores, whose share decreased by 6.0%, and towards Warehouse Clubs and Supercenters, whose share increased by 6.2%. The increase in share of Warehouse stores surely accounts for a large portion of the drop in sales at Food Stores.

Figure 3 also indicates that there has been an increase in sales at Pharmacies and Drugs Stores, whose share of retail sales increased by 1.1% during the period.

A closer look at the smaller categories of retail sales in Figure 4 shows that Clothing Stores have taken a hit, as have Sports and Hobby Stores. It’s likely that most of these decreases have simply shifted from bricks-and-mortar stores to online purchases.

In short, over the past 25 years, we have seen the following trends in retail sales:

  • Large shifts towards bricks-and-mortar warehouse clubs and superstores
  • Large shifts away from bricks-and-mortar grocery stores and department stores 
  • A large shift towards e-commerce
  • Small shifts towards bricks-and-mortar restaurants and pharmacies/drug stores
