Some 2017 Recommendations

Here are some curated recommendations for your holiday watching/reading/listening. I limit my consumption of media (not books). So, like all lists, this one is also highly subjective. (I have no financial interest in recommending these). Movies Kubo and the two strings.  Animated movie (from Laika studios) with a layered and complex narrative. Great for families with kids interested in slightly mature themes (similar to Miyazaki movies). Features a beautiful cover of While My Guitar Gently Weeps by Regina Spektor. On NetFlix. Contratiempo. (The Invisible Guest).  Spanish Crime Thriller and morality play. On NetFlix. Get Out. A brilliant genre-bending film, with the audacity of vision, and taut storytelling. What a directorial debut. Wonder woman. All praise well-deserved.  A blockbuster movie that…

Containers!

The Containers Podcast mini-series (with eight self-contained 30-minute episodes) by Alexis Madrigal at Atlantic is amazing! As an Operations academic in a business school, I am a fan of both nitty-gritty details and narrative story-telling canvas. When I came across the Containers podcast my stoicism vanished, and I was giddy with excitement. Containers are one of those mundane things that fundamentally changed global trade and turned supply chains into complex organisms.  You would be completely mistaken to think that a podcast on containers would be boring. Alexis Madrigal brilliantly weaves logistics facts with human interest stories that form the cogs in gigantic machinery of global trade. He talks about the history of Oakland, the “deaths” of longshoremen, poetry, Filipino lives, logistics,…

Death by a Single Cut? Evaluating “Deals” on E-commerce

An Amazon worker at Chattanooga, Tenn., fulfillment center in August. Photo Credit: Doug Strickland/Associated Press A fascinating article by Laura Stevens on WSJ  (Subscription required) talks about how Amazon sets its third-party “deal of the day”.  The first compelling fact that stood out from the article was the scale of revenues generated by third-party sellers on Amazon. A graph of the total gross merchandise volume (GMV) sold by Amazon, shows that in the recent years, the third-party share of Amazon revenues have increased from 50% to about 70% (even as Amazon’s revenues have exploded). How are these deals evaluated and picked by Amazon? Amazon’s deal of the day selections hinge on two important factors—whether it thinks an item will be…

E-commerce Sales vs. Price

The above chart from Quartz shows how much e-commerce sales in the US have grown because of the low price. In fact, the price level is now comparable to 2000 prices. In short, many goods on e-commerce are being sold on very marginal and progressively diminishing profits.

Dynamic Pricing of Parking Spots

Wired Magazine reports that San Francisco is planning to adjust parking spot prices based on demand, essentially moving to dynamic pricing of parking spots.  Note that SF has been experimenting with the dynamic pricing of spots already. This proposal by San Francisco Municipal Transportation Agency (SFMTA) — which has not been voted by the City Council yet — expands the dynamic pricing spots from the current 7000 meters to 28,000 meters. I’ll make 4 salient points about the issue: (a) Success depends on operational transparency, (b) Roads utilization, not spots, is the main source of congestion,  (c) Dynamic pricing may not improve utilization, and  (d)  Dynamic pricing may hurt consumer welfare. (In fact, I will discuss research evidence that SFPark…

Pricing Hula Hoops

The Hudsucker Proxy is my second favorite Coen brothers movie on rewatchability.1 Within their oeuvre, The Hudsucker Proxy is closest to capturing the humor in American manufacturing/business culture (exceeded only by William H. Macy’s exasperated car salesman role in Fargo). While talking about Dynamic pricing in class, I typically refer to the funny story in Hudsucker Proxy, which has a retailer (ostensibly, all retailers) adjusting the price of HulaHoops in the light of the increased demand. Here is the embedded video from the movie that shows the design of the product, progression into the production process, and testing, leading to its retail sales —  the lifecycle of hope, demise, and rebirth of a product. The movie also features Jennifer Jason…

E-Commerce Boom in China

Online Sales in China exceeded USD 366B in 2016, almost comparable to e-commerce sales in the United States (360B in 2016).  Note that online retail is “only” about 8.5% of the overall retail market in the United States. According to Fortune Magazine, Amazon was 34% of the US e-commerce market.  However, China is an entirely different story. Amazon barely makes an appearance among the big e-commerce contenders.  Taobao – an e-Bay like electronic market place owned by Alibaba commands a lion’s share of the China e-commerce market. Perhaps, even more, impressive is the scale of vertical integration of mobile payment systems with their corresponding e-commerce websites.  For instance, the largest third-party payment system, Alipay, the mobile payment arm of Alibaba, has…
