We show that consumer effort may not be necessarily malevolent and that some sources and measures of greater consumer effort can lead to beneficial outcomes. A better understanding of the role of consumer effort may help firms to evaluate their investments in reducing consumer effort and justify the cost associated with implementing such strategies. First, we suggest that user effort reduction can be beneficial when it concerns the size of the content of the information but not when it regards the involvement of users in the process of getting the information. These opposing effects can be attributed to the mediating role of content learning. Second, we use the complexity of the composition of the recommended choice set as a source of consumer effort and we propose that greater complexity (through increasing consumer effort) increases objective consumer knowledge due to greater required cognitive elaboration but decreases choice confidence and subjective product knowledge. We validate that these effects on product knowledge are managerially meaningful due to their positive effect on website conversion and consumer willingness to pay. In the third study, we examine the role of time as a measure of consumer effort in the context of online product recommendations. We distinguish between consumer inspection time-based effort at the choice set and at the product-level and suggest that whereas in the first case, inspection time decreases website conversion, at the product level, greater inspection time has the opposite effect due to the different antecedents. Accordingly we suggest improvements on the composition of the recommended choice sets in a way that the allocation of consumers’ time spent is effectively balanced. http://repub.eur.nl/res/pub/37703/ 2012-09-14T00:00:00Z The development of advanced recommendation agents (RA's) has rendered more product information available for consumers at a minimal cost. However these decision aids require more effort exerted by users in order to offer recommendations based on their preferences. The construct of effort has showed contradictory effects on outcome quality and evaluation of the decision making process, as effort can be considered as a direct cost (cognitive or time) but also as a benefit (expected accuracy of decision). We conducted an experimental study to test the effect of three different types of perceived effort on the quality perception of a RA. We found a positive effect of perceived RA effort on RA quality perception. This suggests that users want to and should be aware of the RA effort in creating accurate recommendations. The effect of perceived user effort on RA quality is negative, but only when the own effort is perceived as higher than the perceived RA effort. However, this does not hold when user effort regards the navigational aspect of use of the RA which decreases the quality of the RA. We also show that RA quality is a core driver of RA acceptance.
