1. News from Rwanda: An evaluation of the use of small-scale household solar panels in Rwanda finds that there are benefits but those are small and diffuse enough that subsidies will be needed to scale adoption. At the conference itself I learned that while 89% of Rwandans are "financially included" only 6% are "adequately served" according to recent FinScope data--a healthy reminder that heavy caveats are required when setting inclusion goals. The next step is to recognize (with a nod to James Scott) that in markets with high "inlcusion," under-served is a strategy not a condition. And while this isn't news about Rwanda, I learned about it in Rwanda: MFO is conducting garment worker financial diaries in southeast Asia which should help us understand a bit more of the difference between Blattman and Dercon's results in Ethiopia and Heath and Mobarak's results in Bangladesh.
2. The Cost of Volatility: One of the common findings from financial diaries work around the world is the prevalence of income volatility, perhaps most surprisingly among US households. In the US Diaries data we see a lot of the volatility coming from variations in amount earned per week in the same job. There are lots of reasons to suspect that volatile schedules and the income volatility that flows from it is bad for households, but how bad? A new field experiment hints that it's really bad. Mas and Pallais randomize wage offers to potential staff for a national call center and find that workers aren't willing to sacrifice pay for a flexible schedule, but are willing to give up 20% of their wage to avoid having a schedule set by the employer with a week's notice.
