This week in research #138

Here's what caught my eye in research over the past week:

• Akter et al. argue that New Zealand’s low-risk drinking advice is outdated and now overdue for review
• Jones (open access) outlines two scenarios for the impact of artificial intelligence on the economy, providing some guidance about the potential future consequences of AI
• Lee and Porter (open access) provide a simple introduction to the 'weak instruments' problem, including some practical do’s and don’ts implied by the findings of the weak instruments research literature
• Poterba and Werning (open access) summarise the work of last year's John Bates Clark medal winner, Stefanie Stantcheva
