This paper analyzes a randomized controlled trial of a personalized digital counseling intervention addressing informational constraints and choice architecture, cross-randomized with discounts for LARCs. The counseling intervention encourages shared decision-making (SDM) using a tablet-based app, which provides a tailored ranking of modern methods to each client according to their elicited needs and preferences. Take-up of LARCs in the status quo regime at full price was 11%, which increased to 28% with discounts. SDM roughly tripled the share of clients adopting a LARC at full price to 35% and discounts had no incremental impact in this group. Consistent with theoretical models of consumer search, SDM clients evaluated more methods, which led to higher adoption rates for second- or lower-ranked LARCs. Our findings suggest that low-cost individualized recommendations can potentially be as effective in increasing unfamiliar technology adoption as providing large subsidies.","coll_dates":[{"start":"2021-03-09","end":"2022-12-31","cycle":"All"}],"nation":[{"name":"Cameroon","abbreviation":"CMR"}],"analysis_unit":"Client level","data_kind":"Sample survey data [ssd]","notes":"This study is a randomized controlled trial of a personalized digital counseling intervention for long-acting reversible contraceptives (LARCs).
