Evening Must-Read: Simon Wren-Lewis: Greece: A Simple Macroeconomic Guide

What is one supposed to do when confronted by arguments that seem to me--and to everybody else who has been right about the evolution of the North Atlantic economy since 2008--so unprofessional as this piece in Vox? Simon Wren-Lewis begins the needed labor of Hercules here:

Simon Wren-Lewis: Greece: A Simple Macroeconomic Guide: "In 2010 periphery Eurozone countries...

This Vox piece [by Lars P Feld, Christoph M Schmidt, Isabel Schnabel, Benjamin Weigert, Volker Wieland]... displays so much that is wrong with macro arguments coming out of the Eurozone at the moment... ignores the basic macro... denial of the importance of wage and price rigidities... the speed of adjustment matters, and... the article makes no attempt to address this central issue... a complete collapse in GDP, where over half of young people are unemployed... [was not] just par for the course, [but] rather than a function of the amount of austerity imposed... lenders are demanding Greece run significant primary surpluses now, and they need not make this demand.
