conversations Where’s the Optimal Place to Park a Food Truck? Pursuing a love of food and cooking, I completed the basic pastry certificate at Le Cordon Bleu in Paris the summer before starting the PhD program. So I was thrilled to see a crêpe truck, Paris Ouh La La, serving lunch during the school year. After several good meals at the food trucks on Ellis Avenue, and observing the variation in the trucks parked each day, I started thinking about how the trucks decide where to park. Where you choose to locate a business is a fundamental economic question—one that food trucks must re-answer every day. The classic location choice model was offered by the mathematician and economist Harold Hotelling in 1929. Consider two ice cream vendors who parked their carts on a one-mile stretch of beach. Assuming the venders offer roughly the same treats, beachgoers will naturally choose to walk to the closest cart. The vendor on the left will serve all the beachgoers to its left, and the vendor on the right will serve all the beachgoers to its right.
