law of markets

The "law of markets," often associated with economist Jean-Baptiste Say, posits that supply creates its own demand. This means that the production of goods and services generates the income necessary to purchase them, preventing long-term gluts.12

In essence, the interaction of supply and demand determines prices in a market. When the quantity producers want to sell matches what consumers want to buy, the market reaches equilibrium. While Say's law suggests automatic adjustments, critics like John Maynard Keynes have argued that imbalances can occur, especially in the short term. The concept is fundamental to understanding how economies function and allocate resources.3124
