The Marginal Propensity to Splurge

A forthcoming book and academic series from The SCHISM


What happens when equilibrium fails?

For decades, macroeconomic models have relied on elegant assumptions: representative agents, rational optimization, steady-state growth. But what if these assumptions obscure more than they reveal? What if the real engine of economic expansion lies not in productivity, but in pressure—psychological, cultural, and systemic?

A new framework for understanding consumption

The Marginal Propensity to Splurge is a radical rethinking of macroeconomic theory. It proposes that consumption is not merely a function of income, but a dynamic, expressive force shaped by inequality, aspiration, and behavioral heuristics. Drawing on evolutionary psychology, distributional data, and nonlinear modeling, this work introduces a new metric—MPΔC—to capture the agent-level impulse to expand consumption envelopes.

Why it matters

  • Challenges the foundations of orthodox macroeconomic models
  • Explains stagnation, inequality, and growth through endogenous consumption dynamics
  • Reframes consumption as cultural performance, not just utility maximization
  • Offers a new lens for policy, taxation, and fiscal design

What’s coming

This project will be released in two forms:

  • A book, accessible for lay readers of economics, politics, and philosophy
  • A series of academic papers introducing a new macroeconomic model grounded in heterogeneity and emergent behavior

Join the rupture

The SCHISM is more than a platform—it’s a community of critique. If you’re tired of equilibrium dogma, if you believe economic theory should reflect lived reality, if you want to be part of a movement that challenges orthodoxy with precision and polemic—this is your moment.
