Ok, #econtwitter. I want to introduce my 101 students this fall to many economists and show them the variety of interesting questions we work on! So tell me in 2 sentences or less, "What do you do?" Make it accessible to 18-20 year olds in the first (or second) econ class. Thx!

Today, we know that Sahara Desert as a vast sea of sand and salt flats. But up until around 5,000 years ago, this is how it looked.
It was a green landscape of Savannahs, lakes and rivers where early humans lived, hunted and fished.

k = number of heists
p = probability of escape
N = amount of money per heist
After k successful heists, the expected payoff of the next is pN + (1-p)(-kN). Stop robbing when this hits zero. After that payoff is negative.
Thus k = p/(1-p), as De Niro notes in the scene below. https://t.co/OehynnYIqS
