Tim Harford asks “what’s next for behavioral economics?” – nice discussion about the difficulty of knowing when behavioral factors apply, and of the difference between social psychology and behavioral econ.
The big data news this week was the revision of Nigeria’s GDP – the Economist explains “ON SATURDAY, April 5th, South Africa was Africa’s largest economy. The IMF put its GDP at $354 billion last year, well ahead of its closest rival for the crown, Nigeria. By Sunday afternoon that had changed. Nigeria’s statistician-general announced that his country’s GDP for 2013 had been revised from 42.4 trillion naira to 80.2 trillion naira ($509 billion). The estimated income of the average Nigerian went from less than $1,500 a year to $2,688 in a trice. How can an economy grow by almost 90% overnight?” The Economist explains the changes in the base and in data collection which led to this massive change. Morten Jerven offers his take at African Arguments : including why did it take so long “The main reason the rebasing has been delayed has been a lack of basic information from businesses, farmers and households on their output, consumption and income.”
