Krugman's Graph on Food Stamps
By David Henderson
Check out Paul Krugman’s graph of participation in the food stamp (SNAP) program and U6 unemployment. MAKE SURE YOU LOOK ONLY AT THE GRAPH. Don’t read his words around the graph.
Then ask yourself what you think the relationship is between the two variables.
Then, and only then, read what Krugman writes about the relationship, specifically his last sentence. What do you think? Did he get it right?
