  • Ted Miguel on plans for long-term follow-ups of child health and cash transfer programs.
  • Priced out of citizenship? From Stanford News, with the cost of U.S. naturalization now $725, an experiment gave vouchers to cover these costs to low-income immigrants in NYC and found naturalization application rates rose 41%.
  • David Deming in the NBER reporter on the value of soft skills in the labor market: “the very term soft skills reveals our lack of understanding of what these skills are, how to measure them, and whether and how they can be developed... Social interaction is perhaps the most necessary workplace task for which there is currently no good machine substitute... Researchers ought to stop relying on convenient, off-the-shelf measures of soft skills and start creating metrics that are theoretically sound and suitable for the task at hand”

Money matters in education. Recent evidence from the United States shows that increased education spending results in more completed years of schooling and higher subsequent wages for adults. Spending cuts during the Great Recession – also in the U.S. – were associated with reduced student test scores and graduation rates.

  • Duncan Green summarizes Stefan Dercon’s view of 10 top thinkers in development. E.g. on Acemoglu and Robinson “their policy advice is just ‘buy yourself a better history/don’t start from here’. Not very useful for aid”. Alice Evans responds to the lack of women on Stefan’s list with five big problems in development and female scholars to learn from on these.
  • How did Chinese consumption respond to changes in the minimum wage? Dautovic and co-authors on VoxEU report that “For the period 2002-2009, we identify more than 13,874 changes in the local minimum wage across China's 2,183 counties and 285 cities…many counties experienced substantial nominal increases in their minimum wage above 20%...we show that low-income households spend their entire additional income from a higher minimum wage…for poorer households, 40% of the additional minimum wage income is spend on health care and educational expenditure”
  • Looking to try out machine learning for poverty prediction? The World Bank has launched a competition (with prize money) to see how well you can predict poverty.

Statistical Power and the Funnel of Attribution

Often there are many steps or stages between the starting point of some intervention and its ultimate goal, and at each step, people can drop out. The result can be extremely low power to measure impacts on this end outcome, even though we might be able to detect impacts on the intermediate steps. This post illustrates this point, with the goal of making clear the importance of trying to measure intermediate outcomes, and concludes with suggestions of ways to partially overcome this problem.
