The Great Accretion and the Great Depression

The abridged abstract:

"The Second Industrial Revolution sparked a wave of new products and industrial processes, fueling an optimistic Roaring Twenties. But did excitement about technological progress contribute to an over accumulation of investment, despite a slowdown in new product development and satiated demand during the 1920s? And, was this over investment worsened by continuous process innovation? Could these factors have played a role in triggering the Great Depression? ... The answer is yes."
