    Abstract: While almost all charities rely on a set of donor appreciation strategies, their effectiveness for the success of fundraising campaigns is underresearched. Through two preregistered field studies conducted in collaboration with a leading German opera house (N=10, 000), we explore the significance of expressing gratitude and examine two different approaches to doing so. Our first study investigates the impact of a "thank you in advance" statement in fundraising letters, a common strategy among fundraisers. In the second study, we explore the effectiveness of handwritten thank-you postcards versus printed postcards, shedding light on the roles of personalization and handwriting in donor appeals. Our findings challenge conventional wisdom, revealing that neither "thank you in advance" nor handwritten thank-you notes significantly affect donor contributions.

    Abstract: Despite growing enthusiasm about the potential of digital innovations to transform agrifood systems, adoption among smallholder farmers in Africa remains low and heterogeneous. While the proliferation of digital tools targeting smallholder farmers is encouraging, the vast majority remain at pilot stages, facing important demand and supply-side barriers to adoption. This paper evaluates alternative digital literacy interventions designed to address these demand-side barriers. Following a Training of Trainers (TOT) model, we designed and implemented a randomized control trial to test three variants of digital literacy training: standard classroom-based digital literacy training (T1), digital training complemented (preceded) by a video-based play (T2), digital training complemented (preceded) by a live community play (T3), and a control group (C). We find that all variants of digital training significantly increased the uptake and utilization of digital tools by smallholder farmers. Specifically, the standard digital training alone increased uptake by 20 percentage points and utilization by 26 percentage points. The interventions also significantly enhanced farmer trust in digital tools by 8–13 percentage points. Surprisingly, for some outcomes, the digital literacy training alone outperformed the combined approaches that incorporated edutainment nudges. We explore possible explanations, including group size effects and social influence dynamics during the plays. We also document heterogeneity in the impact of these interventions across farmers’ gender and age. Our findings offer insights for designing cost effective and scalable interventions to build digital capabilities and trust among smallholder farmers.
