In this session of Yale instructor Paul North's chapter by chapter study of Marx's Capital, Volume 1, the lecture addresses what Marx calls expanded or expanding reproduction, the process by which value continuously valorizes itself and becomes capital on an ever-larger scale. North builds on the prior class's introduction of simple reproduction, showing how Marx extends the concept into a dynamic model of capitalist growth. The lecture continues the course's close, chapter by chapter reading of the 1872 text, preparing the ground for the following session's focus on the general law of capital accumulation.
