Abstract

Do well-informed politicians make more effective spending decisions? In experiments with 70% of all elected politicians in Malawi ($ N=460 $), we tested the effects of information on public spending. Specifically, we randomly provided information about school needs, foreign aid, and voting patterns prior to officials making real decisions about the allocation of spending. We show that these information interventions reduced inequalities in spending: treatment group politicians were more likely to spend in schools neglected by donors and in schools with greater need. Some information treatment effects were strongest in remote and less populated communities. These results suggest that information gaps partially explain inequalities in spending allocation and imply social welfare benefits from improving politicians’ access to information about community needs.

Figure 1. Sources of Constituency Information for Elected CouncilorsNote: This figure summarizes responses from a survey of a randomly selected sample of 110 councilors involved in this study.

Figure 1

Figure 2. Distance and Councilor VisitsNote: This figure shows the mean number of citizens reporting at least one visit from their councilor grouped by how far away (in percentiles) they are from the councilor’s hometown. Vertical lines show 95% confidence intervals adjusted for village-level clustering. See SM Table S1 for tabular estimates.

Figure 3. School Knowledge QuestionsNote: The x-axis shows the percentage of politicians responding correctly to questions about the characteristics of three randomly selected schools in their constituencies. All questions are multiple-choice except for the question on the name of the donor. The top dark line shows the proportion of correct answers we would expect if politicians answered randomly.

Figure 4. Sampled ConstituenciesNote: This figure shows the constituencies of politicians in the sample.

Figure 7. Association between School Characteristics and School SelectionNote: This figure shows exponentiated coefficients from separate conditional logistic regressions of school selection on each variable. The sample is limited to maps that do not contain the information treatment related to each school characteristic. Ninety-five percent confidence intervals are shown in the horizontal lines. Standard errors are clustered on politician. Continuous variables are normalized for comparison purposes. See SM Tables S2–S7 for tabular estimates.

Figure 8. Effects of Need Information on School SelectionNote: Circles indicate estimated effects of School Need Index on the odds of a school being selected in the control group (those appearing on maps without the Need Information Treatment). Triangles indicate estimated effects in the treatment group (those appearing on maps with the Need Information Treatment). Horizontal lines indicate 95% confidence intervals. The p-values on the left indicate the probability our treatment estimate is consistent with a null effect. For estimates in tabular form, see SM Tables S8 and S9.

Effects of Aid Information on School SelectionNote: Circles indicate estimated effects of Aid Project Count or Aid Good Types on the odds of a school being selected in the control group (those appearing on maps without the Aid Information Treatment). Triangles indicate estimated effects in the treatment group (those appearing on maps with the Aid Information Treatment). Horizontal lines indicate 95% confidence intervals. The p-values on the left indicate the probability our treatment estimate is consistent with a null effect. For estimates in tabular form, see SM Tables S10 and S11.

Effects of Voting Information on School SelectionNote: Circles indicate estimated effects of Percent Votes on the odds of a school being selected in the control group (those appearing on maps without the Voting Information Treatment). Triangles indicate estimated effects in the treatment group (those appearing on maps with the Voting Information Treatment). Horizontal lines indicate 95% confidence intervals. The p-values on the left indicate the probability our treatment estimate is consistent with a null effect. For estimates in tabular form, see SM Tables S12 and S13.

Figure 11. Interaction Effects of Information Treatments and Distance, Population, and VotingNote: This figure shows conditional average treatment effects of each information treatment (in odds). In columns A, B, and C, we show the effects for Need Information, Aid Information, and Voting Information, respectively. In rows 1, 2, and 3, we show how these conditional average treatment effects vary by the school’s distance from the politician’s hometown, population density at the school, and the percentage of votes for the politician at the nearest polling station to the school. All x-axes are shown in percentiles. For estimates in tabular form, see SM Tables S14–S16.
