To comprehend the"expansive dynamism of capitalism"9 one needs an understand- ing of the micro processes underlying macro outcomes.0 Although social interaction is partly based on routines,the"reflexive"part of human agency can be described as decisions.It is this part of social interaction that I am focusing on.Decisions are based on expectations regarding outcomes.Thus it is expectations that establish which eco- nomic activities are pursued or abstained from.However,under conditions of funda- mental uncertainty,expectations cannot be understood as being determined through calculation of optimal choices taking into account all available information,but rather are based on contingent interpretations of the situation in the context of prevailing institutional structures,cultural templates,and social networks. The suggestion brought forward is that the dynamics of capitalism looked at from the perspective of social interaction can be analyzed proceeding from the notion of fictional expectations.By the term"fictional expectations"I refer to present imaginar- ies of future situations that provide orientation in decision making despite the incalcu- lability of outcomes.12"Fictionality"in economic action does not mean the "falsity"or "fantasy"that is also conveyed in the word fiction.Instead,it refers to the future being unforeseeable so that expectations,rather than being forecasts,must inhabit the mind as imagined future states of the world.Expectations under conditions of uncertainty should be understood as pretending future states of the world,allowing actors to act as ifthis imaginary would indeed become the"future present."13 Actors are motivated in their actions by the imagined future state and organize their activities based on these mental representations.Fictional expectations in the economy take narrative form as stories,theories,and discourses.Because these representations are not confined to empirical reality,fictionality is also a base of creativity in the economy and thereby a source of the dynamics of capitalism.Including the notion of fictionality opens up a way to understanding the microfoundations of the economy's dynamics and growth.
