Mobile money services give trade benefits such as bill payment, decreased transaction costs and time, expanded savings possibilities, sales, and convenience. Despite the benefits, traders in Uganda are still slow to adopt and use mobile money services. This article reflects on the findings of a study that looked at the barriers that merchants experience while utilizing and implementing mobile money services in Uganda. A self-administered questionnaire was utilized to obtain data from 394 survey respondents. A model for encouraging traders to use mobile money services is offered. The suggested model expands on the Unified Theory of Technology Acceptance and Use. According to regression study, performance expectancy, social factors, and sensitization components all have a substantial impact on the behavioral intention of mobile money service uptake for trade. On the other hand, security and effort expectation had no significant affect on traders' behavioral intention to use mobile money services. Furthermore, the data show that enabling conditions affected the utilization of mobile money services for commercial transactions. The suggested approach is adaptable and generic, and it may be used in other developing nations with comparable circumstances to Uganda.

Abstract. The mixed-effects location scale model is an extension of a multilevel model for longitudinal data. It allows covariates to affect both the within-subject variance and the between-subject variance (i.e., the intercept variance) beyond their influence on the means. Typically, the model is applied to two-level data (e.g., the repeated measurements of persons), although researchers are often faced with three-level data (e.g., the repeated measurements of persons within specific situations). Here, we describe an extension of the two-level mixed-effects location scale model to such three-level data. Furthermore, we show how the suggested model can be estimated with Bayesian software, and we present the results of a small simulation study that was conducted to investigate the statistical properties of the suggested approach. Finally, we illustrate the approach by presenting an example from a psychological study that employed ecological momentary assessment.
