The practice of child marriage is still prevalent in several pockets in Indonesia and often leads to discontinuation of post-primary education, particularly among girls. Our proposed intervention aims to reduce the incidence of child marriage and improve post-primary education outcomes by addressing the underlying factors of child marriage: religious beliefs and present bias. An information campaign, which provides an alternative religious view about child marriage and raises awareness about the risks associated with child marriage, will be delivered through short videos shown as intermissions during community movie screenings or religious gatherings. We design a three-arm cluster randomized controlled trial at the school level to test the effectiveness of information campaign and the content of the information campaign. We deliver the intervention via WhatsApp to mitigate the limitations of face-to-face interaction. The impact evaluation will be conducted in Central and East Java, in districts with high incidences of child marriage. The immediate outcomes of interest are perception and attitudes toward child marriage issues, while the long-run outcomes are educational attainment.

Experimental Details


We plan to screen short narrative videos, aimed at changing the viewers’ perceptions and attitudes towards child marriage. First, the videos will provide an alternative religious view delivered by a male religious leader which discourages child marriage, aimed to address societal pressure that is shaped by the perceived religious code.

Second, the short videos are intended to raise awareness about the costs of child marriage and the benefits of delaying such practice. The message about the costs and benefits aims to address myopic preferences toward child marriage. Lastly, the messages in the videos will be delivered through scripted narration to be acted by actors to ensure that messages are accessible to audience from various socioeconomic and educational background.

Experimental Design

Experimental Design
Our intervention design includes three treatment arms: control schools A, treatment schools B, and treatment schools C. In the control schools (A), we will only screen a video that conveys health messages about the Covid-19 pandemic. Whereas in treatment schools, we will show the health message video and a short movie. In treatment schools B, the key messages in the short movie address the issue of present bias. In treatment schools C, the key messages in the short movie address the issues of present bias and religious beliefs.
