Since 2011, we have struggled to reconcile the poverty trends from two complementary poverty monitoring sources in Malawi. From 2005 to 2009, the Welfare Monitoring Survey (WMS) was used to predict consumption and showed a solid decline in poverty. In contrast, the 2004/05 and 2010/11 rounds of the Integrated Household Survey (IHS) that measured consumption through recall-based modules showed no decline.
Today’s blog post is about a household survey experiment and our working paper, which can, at least partially, explain why complementary monitoring tools could provide different results. The results are also relevant for other tools that rely on vastly different instruments to measure the same outcomes.

Imagine you are out on a pretest of a survey. Part of the goal is to measure the rights women have over property. The enumerator is trying out a question: "can you keep farming this land if you are to be divorced?" The woman responds: "it depends on whose fault it is." Welcome to yet another land where no one has heard of no-fault divorce.
One of the things I learned in my first field work experience was that keeping interviews private was critical if you wanted unbiased information. Why? I guess at the time it should have been kind of obvious to me – there are certain questions that a person will answer differently depending on whom else is in the room. We were doing a socio-economic survey of rural households in Ghana, and we thought that income, in particular, would be sensitive, since spouses tended to share information on this selectively and perhaps in a strategic way.
