"Éléments d'économie politique pure" is a foundational work by the French economist Jean-Baptiste Say, published in 1803. The book outlines the principles of political economy, focusing on production, distribution, and consumption of goods. Say emphasizes the role of entrepreneurs in driving economic growth and the importance of free markets. In this work, Say introduces the concept of the "Say's Law," which posits that supply creates its own demand. This idea suggests that production inherently generates the means and desire for consumption, challenging the notion of overproduction. The book significantly influenced classical economics and laid the groundwork for future economic theories.
