Who among the following theorists has written on affective economies?

The correct option is Sara Ahmed.

Sara Ahmed is a prominent feminist writer and independent scholar whose work lies at the intersection of feminist theory, queer theory, critical race theory, and postcolonialism.
She is widely recognized for developing the concept of "affective economies" in her influential 2004 journal article titled "Affective Economies" (published in Social Text) and further elaborating on it in her landmark book, The Cultural Politics of Emotion (2004).

In her theory of affective economies, Ahmed argues that emotions do not reside within individuals or objects as private or inherent properties. Instead, emotions function as an economy: they circulate, accumulate, and align individuals with collectives. Through this circulation, emotions shape the surfaces of bodies and create boundaries between the "self" and the "other," as well as "us" and "them." According to Ahmed, affect is social, material, and deeply political rather than purely psychological.
