goodsmarkets

Goods markets, also called product markets, are where households and firms exchange final goods and services. In these markets, the price and quantity of goods are determined by the interaction of buyers' demand and sellers' supply. The primary price signal is the market price, which coordinates production decisions and resource allocation. Demand for goods comes from households' consumption, firms' planned investment, government spending on goods and services, and net exports. Supply comes from firms' production decisions, influenced by costs, technology, and capacity.

Equilibrium in the goods market occurs where planned expenditure equals output (or where aggregate demand equals aggregate supply). If demand exceeds supply, inventories fall and firms respond by increasing production or prices; if supply exceeds demand, inventories rise and production and prices may fall. Over time, price adjustments, inventory signals, and expectations guide how the market returns to equilibrium. In the short run, prices may be sticky, delaying adjustment and producing fluctuations in output and employment.

In macroeconomic models, goods markets interact with other markets: monetary policy affects demand via interest rates, fiscal policy through government spending and taxes, and open-economy channels through exchange rates and net exports. The state of goods markets is often summarized by the level of aggregate demand and the level of real GDP. In microeconomics, goods markets may exhibit competition, pricing, and market structure that influence consumer welfare and producer profits.
