WSJ: Drive-Thru AI Chatbot vs. Fast-Food Worker

In this video from The Wall Street Journal, senior personal tech columnist Joanna Stern examines the performance of an AI chatbot versus a fast-food worker. Are these two inputs clearly substitutes or are their complementarities that could be exploited by companies? If the goal were only to produce the same amount of food as before with lower costs, we might expect to see a reduction in fast-food workers. However, this technological improvement may end up increasing output and subsequently requiring more tech and more labor.

The Office — Automated Assitant

A new phone system can replace many of Pam’s tasks. She normally spends her day connecting incoming calls to different sales people and departments, but this new phone system will make it so that anyone calling Dunder Mifflin can dial directly to the department they want. She thinks she still has value at putting our candy, but then realizes a vending machine can do that as well.

Jim swoops in to save Pam and play the role of Michael Scott, the branch manager. Jim is in love with Pam and doesn’t want to see her fired, so he acts like Michael and tells the salesman that they aren’t interested. He’s almost busted, but luckily gets away with it.

Construction Site in Thailand

A few years back there was a popular video of a human powered ferris wheel in India. I use that clip to talk about labor abundance in the Heckscher–Ohlin model of trade since India is so labor-abundant. Earlier we came across this fantastic video of a construction site in Thailand (another labor rich country). For small construction jobs, the workers will use manpower (literally) instead of machines to drive piles into the ground. This clip could also be used in a labor economics setting if you’re talking about substitutes in production. Either way, this is a fun-video for class with a pretty nice beat from the tambourine-wielding foreman.
