This is a fairly wide ranging conversation that the economist Tyler Cowen had with...the Economist magazine! Cowen has become an important voice in the popular and academic econ conversation through his blog, Marginal Revolution, and his e-book, "The Great Stagnation: How America Ate All The Low-Hanging Fruit of Modern History, Got Sick, and Will (Eventually) Feel Better."
I zeroed in on his comments about firing bad teachers, a major issue in Southern California. This has come to a head recently, as LAUSD is conducting an experiment in teacher evaluation but hasn't asked the teachers' union for input, according to this UPI report.
You might not agree with Cowen's views on this controversial subject. But he's usually worth listening to. Or in this case, listening to while he drinks tea and discusses the impending crack-up of the Chinese economy.
