This study discusses the influence of product involvement and decision complexity on consumer perceived time pressure involving time constrained marketing offerings. This study further proposes one model integrating product characteristics (product involvement and decision complexity), perceived time pressure, perceptions regarding shopping tasks (perceived risk, perceived quality, and perceived fulfillment of shopping task), and shopping consequences (price level of the chosen item and customer satisfaction). Findings include: (1) decision complexity (compared with product involvement) is more influential to perceived time pressure given the same time constraint imposed on participants and (2) perceived time pressure increases perceived risk and lowers perceived quality and perceived fulfillment of shopping task, and then indirectly lowers customer satisfaction.
