This paper introduces a new theory about why firms exist, focusing on how they learn and adapt. It compares when it's better for a firm to learn within itself or from the market. The theory suggests that firms can be more efficient when they align their learning processes with their organization structure. The study identifies factors that determine whether a firm or the market is more advantageous for learning. Overall, the research suggests that understanding how firms learn can help explain why some companies perform better than others.
