Oil prices plummeted from over​ $100 per barrel in​ mid- 2014 to under​ $30 in early 2016. According to a Reuters​ article, oil traders in 2015 and 2016 put massive amounts of oil in storage​ (even on tankers at​ sea), anticipating higher prices in the future. The article noted that in early​ 2017, "traders are turning the spigots to drain the priciest storage tanks holding U.S. crude stockpiles as strengthening markets make it unprofitable to store for future​ sale." Holding some oil in storage rather than selling it would

decrease the supply of oil, shifting it to the left.

Like many other​ cities, Denver experienced a sharp decline in construction of new houses in the years following 2006. Many​ carpenters, roofers, and other skilled workers left the area or found jobs in other industries. In​ addition, builders stopped buying and preparing home lots for construction.

In the future, the price increases of new houses in Denver can be expected to be

smaller because supply is more elastic over time.
