In the last two decades, happiness has moved into the focus of economic inquiry. Frey and Stutzer (“What Can Economists Learn from Happiness Research”, Journal of Economic Literature 20, 2002, pp. 402-435) argue convincingly that gross domestic product (GDP), unemployment, inflation, and many other indicators of economic performance are primarily interesting because they are correlated with the well-being of people.

As argued by Omer Moav and Zvika Neeman in a 2012 paper (Moav taught at ISET in the past), boasting is a way to pretend that one has hidden income (“Saving Rates and Poverty: The Role of Conspicuous Consumption and Human Capital”, Economic Journal 122, pp. 933-956). While people may have a rough idea of the incomes of their neighbors, colleagues, friends, and other people they interact with, they usually do not know exactly how much they make.

One of the first things tourists in Georgia notice is how crazy that drive from the airport to the city is. Jumping red lights, breaking rules to take over the jeep in front, the Georgian taxi driver risks his (and not only his!) life to deliver his passenger to the destination. As a distraction from the dangerous ride, the driver might offer the famous “dzhigit” (a brave equestrian) joke: a dzhigit passes on the red light but stops on the green – in case another dzhigit is crossing the road.

One of the most fundamental assumptions in mainstream economics is the rationality of humans. Yet, as argued by Timothy A. Pychyl, professor of psychology at Carleton University in Canada, frequently observed procrastinating behavior, i.e. the “needless voluntary delay” (Pychyl), cannot be reconciled with the rational man paradigm.

When I left Russia back in late 2006, attempting to cross a busy Moscow street bordered on suicide. Instead of slowing down before a zebra crossing, Russian drivers were in the habit of accelerating so as to signal their intention NOT to stop. Understandably, pedestrians had no choice but to adjust their street crossing strategies accordingly.
