  1. Arnold Kling gives an An Opinionated Guide to Educational Technology
    Here, I offer my own assessment of the prospects for technologies to revolutionize education.
  2. Peter Klein on The Wrong Way to Measure Returns to Public Science Funding
    A new Milken Institute report purports to show that “[t]he benefit from every dollar invested by National Institutes of Health (NIH) outweighs the cost by many times. When we consider the economic benefits realized as a result of decrease in mortality and morbidity of all other diseases, the direct and indirect effects (such as increases in work-related productivity) are phenomenal.” There are so many problems with the study I hardly know where to begin.
  3. Robert J. Gordon asks Is US economic growth over?
    Global growth is slowing – especially in advanced-technology economies. This column argues that regardless of cyclical trends, long term economic growth may grind to a halt. Two and a half centuries of rising per-capita incomes could well turn out to be a unique episode in human history.
  4. Harun Onder asks What does trade have to do with climate change?
    As multilateral attempts for climate-change mitigation stall, the two-way relationship between trade and climate change is likely to come under further scrutiny. This column explains how liberalised trade has several climate-related consequences. It argues that trade policy could enforce mitigation policies but that multilateral conventions are crucial in preventing undesired protectionist consequences.
  5. Chris Dillow on The Productivity Puzzle
    UK labour productivity is falling. Today's figures show that total hours worked have risen 1.6% in the last year, whilst the NIESR estimates that GDP fell 0.2% in the time. GDP per hour is now 4.5% below 2007Q4's level. Had productivity continued to grow at its 1977-2007 rate, it would be 10.8% higher.
  6. Erik Brynjolfsson on Big Data’s Management Revolution
    Big data has the potential to revolutionize management. Simply put, because of big data, managers can measure, and hence know, radically more about their businesses, and directly translate that knowledge into improved decision making and performance. Of course, companies such as Google and Amazon are already doing this. After all, we expect companies that were born digital to accomplish things that business executives could only dream of a generation ago. But in fact the use of big data has the potential to transform traditional businesses as well.
  7. John Taylor on A New Chart Cast on the Bad News Recovery
    As many have observed the employment report for August released today was disappointing news, but it really is a continuation of a steady stream of bad employment news that has been the story of this recovery since its beginning. The economy is growing too slowly to increase jobs at a pace that matches the growing population—unlike previous recoveries from deep recessions.
