When economic professors making simple (MS Excel) coding mistakes …


Basic MS Excel mistake in a paper published by two Harvard Economic Professors in a top-tier Economic journal!?

This week, the hottest topic in economics or even in academia as a whole would be the paper publishes by Thomas HerndonMichael Ash and Robert Pollin |  (HAP) on 4/15/2013 critiquing a widely cited paper by Reinhart and Rogoff on the debt ration and GDP of many countries titled “Growth in a Time of Debt“.

What is exciting is that HAP argue that R&R has made an error when using MS Excel to analysis such macroeconomic data. That paper by HAP titled “Does High Public Debt Consistently Stifle Economic Growth? A Critique of Reinhart and Rogo ff” would probably one of legendary critique papers in economics to date.
