Consider:
–The economist Greg Mankiw had an essay in the New York Times last week on five theories as to why growth has been so sluggish for so long (Greg’s focus was on the US, but it could have applied to Europe as well). Mankiw, a Harvard professor and writer of widely used textbooks, has long been at the top of the field. Almost a decade after a deep recession that “no one saw coming” (as is widely claimed) and seven years of a tepid recovery, he presents five different diagnoses, ranging from mismeasurement to weak demand to “policy missteps.”
