讲座主要内容：

Crowdsourced freight logistics platforms have adopted Context-Aware Finite Recommender Services (FRS) to cater to time-sensitive service demands. Presenting users with a reduced set of matched recommendations in batches, FRS is devised to induce users’ choice urgency and avoid choice delay. However, there is a dearth of research that attempts to unravel the effects of batch presentation on choice urgency. Anchored on expected utility theory, we scrutinize the role of current and historical choice variability within and across batches in generating choice urgency by first mathematically analyzing users’ decision models and then empirically validating the propositions in a massive dataset of order recommendation records from a leading crowdsourced platform. Both mathematical models and empirical results reveal that current intra-batch diversity induces choice urgency while current inter-batch growth, historical intra-batch diversity and historical inter-batch diversity discourage choice urgency. Findings from this study contribute to extant literature on recommender services by unraveling how the design of FRS impacts user choice behavior, with critical insights offered to relevant practitioners around crowdsourced freight logistics.
