A Single-blinded Randomized Controlled Trial to Estimate the Impact of Information to Change Japanese Attitudes towards ODA

Using a survey-embedded experiment, this paper tests whether the active provision of information can generate support, albeit tentatively, for ODA and/or the intention to participate in development aid among Japanese citizens. Results reveal that the treatment can increase the level of support for ODA on average, especially in terms of the efficient use of money irrespective of citizens’ attributes and pre-intervention opinions on development cooperation. Based on these results, development education featuring Aid-effectiveness is strongly recommended as the most efficient communication strategy.
