We are thrilled that Steven Landsburg will be guest blogging at Marginal Revolution over the next week! No one is better at explaining complicated ideas than Steven, his columns and books are a marvel of both clarity and depth. When you read a Landsburg column you first learn why the obvious idea is wrong but uniquely by the time you get to the end of a Landsburg column you also know why the correct idea is obvious! I remember my reaction the first time I read Steven’s explanation of Ricardian Equivalence (in Macroeconomics written with Lauren Feinstone). What a revelation! It’s so obvious! And that was after I already “understood” the idea!
