Many technology projects in government are developed and implemented with third party organizations through public-private partnerships. This project studies how e-government collaborations between third parties and government affect people’s trust in government and uptake of online public services in Kenya. We use an endorsement-style survey experiment to study whether trust can be transferred from a trusted company to the government. Randomizing respondents into learning about a new online public service portal delivered by 1) a firm, 2) government, or 3) a partnership between the firm and government, we find that learning about the partnership does not increase respondents’ trust in government and thus do not find support for trust transfer. However, we do find support for other pathways where this online portal impacted trust in government. Specifically, we find a substitution effect, where respondents are more willing to use the online portal when they learn it is delivered by the company, but also trust the government less. We also find that respondents’ pre-existing levels of trust in government lead to differing results, where the substitution effect seems to be driven by those who already have low trust in government at baseline. This study helps us understand conditions under which trust transfer is more likely to occur and highlights other ways trust can be affected through digitization efforts.
