Financial pricing formulas actively construct the markets they purport to measure

Evidence

Whether it is Callon’s investigations of financiers’ use of modelling technology or MacKenzie’s analysis of the production of financial instruments, these scholars are interested in what we might call the sociology of financial meaning-making. MacKenzie, for instance, has been at the forefront of identifying financial instruments as ā€œperformativeā€: according to MacKenzie, formulae like the famous Black–Scholes mechanism for derivative pricing do not simply reveal underlying market realities. Because they influence and shape subsequent financial decisions and the financial milieu more broadly, these formulae actively shape and build market realities. They are, in MacKenzie’s words, ā€œan engine, not a cameraā€: they do not simply measure market realities; they help bring them into being. — Max Haiven, Cultures of Financialization, 84

Categorization

  • DEFINE: Defines the performativity thesis in the sociology of finance — the claim that instruments like Black-Scholes shape rather than merely measure markets.
  • XREF: Connects directly to deWaard’s cultural argument about finance colonizing imagination — this is the intellectual foundation for that claim. — connects to: Traders’ arbitrage activity made the pricing model appear empirically true — Donald MacKenzie & Yuval Millo, Constructing a Market, Performing Theory, 126; Markets carry explicit traces of the specific pricing models they use — Donald MacKenzie, An Engine, Not a Camera: How Financial…, 899; Financial instruments shape markets rather than merely read them — Max Haiven, Cultures of Financialization, 401 (+10 more)
  • ADDENDUM: Feeds the financialization-into-culture argument this chapter builds toward; supports the bridge to the reader’s stated goal.
  • SEED: Angle: how the ā€˜engine not a camera’ insight extends beyond derivatives to everyday financial tools — credit scores, mortgage calculators, retirement planning apps all construct behavior they claim to measure.
