PurposeThe study aims to examine the characteristics of product portfolio on the price premium of an umbrella brand. Specifically, the study seeks to explore three aspects of a product portfolio: the presence of attribute compatibility, similarity, and portfolio size.Design/methodology/approachA total of 232 subjects participated in the 2 (with/without compatibility)×2 (product sets: high similarity/low similarity)×3 (portfolio size: small, medium and large). Results support the hypothesis about the three factors.FindingsExperimental results show that subjects on average are willing to pay a 9.45 percent price premium for the brand with the attribute‐compatible portfolio. The effect of attribute‐compatibility is more obvious for a similar than a dissimilar portfolio. In addition, larger portfolios dilute the price premium.Originality/valueThe study first addresses the factor of attribute compatibility among a product portfolio. A product portfolio with attribute compatibility has features linking products together. For example, the “direct‐print” feature among Canon products allows its cameras to print directly on Canon printers. The study finds that such a feature increases a brand price premium by 9.45 percent.

This article concerns feminist engagements with epistemologies. Feminist epistemologies have revealed and challenged the exclusions and denigrations at work in knowledge production processes. And yet, the emphasis on the partiality of knowledge and the non-innocence of any subject position also cast doubt on the possibility of feminist political communities. In view of this, it has been argued that the very parameter of epistemology poses limitations for feminism, for it leads to either political paralysis or prescriptive politics that in fact undoes the political of politics. From a different perspective, decolonial feminists argue for radical epistemic disobedience and delinking the move beyond the confines of Western systems of knowledge and its extractive knowledge economy. Nevertheless, the oppositional logic informs both feminist epistemologies and its critiques, which I argue is symptomatic of the epistemic habits of academic feminism. This article ends with a preliminary reconsideration of the question of origin through the figure of zero. It asks whether it might be possible to conceive of feminist epistemologies as performing the task of counting zero -accounting for origin, wholeness, and universality -that takes into account specificities without forfeiting coalition and claims to knowledge.
