I want to talk a little bit today about labor and work.
    When we think about how people work, the naive intuition we have is that people are like rats in a maze—that all people care about is money, and the moment we give them money, we can direct them to work one way, we can direct them to work another way. This is why we give bonuses to bankers and pay in all kinds of ways. And we really have this incredibly simplistic view of why people work, and what the labor market looks like.
    At the same time, if you think about it, there’re all kinds of strange behaviors in the world around us.
    Think about something like mountaineering and mountain climbing. If you read books of people who climb mountains, difficult mountains, do you think that those books are full of moments of joy and happiness? No, they are full of misery. In fact, it’s all about frostbite and having difficulty walking, and difficulty breathing-cold, challenging circumstances. And if people were just trying to be happy, the moment they would get to the top, they would say, ’’This was a terrible mistake. I’ll never do it again. ’’
    ’’Instead, let me sit on a beach somewhere drinking mojitos. ’’But instead, people go down, and after they recover, they go up again. And if you think about mountain climbing as an example, it suggests all kinds of things. It suggests that we care about reaching the end, a peak. It suggests that we care about the fight, about the challenge. It suggests that there’s all kinds of other things that motivate us to work or behave in all kinds of ways.
    And for me personally, I started thinking about this after a student came to visit me. This was one of my students from a few years earlier, and he came one day back to campus. And he told me the following story: He said that for more than two weeks, he was working on a PowerPoint presentation. He was working in a big bank, and this was in preparation for a merger and acquisition. And he was working very hard on this presentation—graphs, tables, information. He stayed late at night every day. And the day before it was due, he sent his PowerPoint presentation to his boss, and his boss wrote him back and said, ’’Nice presentation, but the merger is canceled. ’’And the guy was deeply depressed. Now at the moment when he was working, he was actually quite happy. Every night he was enjoying his work, he was staying late, he was perfecting this PowerPoint presentation. But knowing that nobody would ever watch it made him quite depressed.
