The Effect of SMS on Participation: Evidence from Uganda

I’ve been wanting to post about this paper for a while. At the intersection of technology and citizen participation this is probably one of the best studies produced in 2013 and I’m surprised I haven’t heard a lot about it outside the scholarly circle.

One of the fundamental questions concerning the use of technology to foster participation is whether it impacts inclusiveness and, if it does, in what way. That is, if technology has an effect on participation, does it reinforce or minimize participation biases? There is no straightforward answer, and the limited existing evidence suggests that the impact of technology on inclusiveness depends on a number of factors such as technology fit, institutional design and communication efforts.

If the answer to the question is “it depends”, then the more studies looking at the subject, the more we refine our understanding of how it works, when and why. The study, “Does Information Technology Flatten Interest Articulation? Evidence from Uganda” (Grossman, Humphreys, & Sacramone-Lutz, 2013), is a great contribution in that sense. The abstract is below (highlights are mine):

We use a field experiment to study how the availability and cost of political communication channels affect the efforts constituents take to influence their representatives. We presented sampled constituents in Uganda with an opportunity to send a text-message to their representatives at one of three randomly assigned prices. This allows us to ascertain whether ICTs can “flatten” interest articulation and how access costs determine who communicates and what gets communicated to politicians. Critically, contrary to concerns that technological innovations benefit the privileged, we find that ICT leads to significant flattening: a greater share of marginalized populations use this channel compared to existing political communication channels. Price matters too, as free messaging increase uptake by about 50%. Surprisingly, subsidy-induced increases in uptake do not yield further flattening since free channels are used at higher rates by both marginalized and well-connected constituents. More subtle strategic hypotheses find little support in the data.

But even if the question of “who participates” is answered in this paper, one is left wondering “as to what effect?”. Fortunately, the authors mention in a footnote that they are collecting data for a companion paper in which they focus on the behavior of MPs, which will hopefully address this issue. Looking forward to reading that one as well.
