Prof. Alexander Teytelboym (University of Oxford): "The Equilibrium Existence Duality: Equilibrium with Indivisibilities & Income Effects" – We show that, with indivisible goods, the existence of competitive equilibrium fundamentally depends on agents’ substitution effects, not their income effects. Our Equilibrium Existence Duality allows us to transport results on the existence of competitive equilibrium from settings with transferable... [more]
