keresletváltozás

Keresletváltozás, meaning "demand change" in Hungarian, refers to a shift in the quantity of a good or service that consumers are willing and able to purchase at various price levels. This change is distinct from a movement along the demand curve, which is caused solely by a change in the price of the good itself. Instead, a keresletváltozás is driven by factors external to the price of the specific product.

Several factors can lead to a keresletváltozás. Changes in consumer income are a primary driver. If incomes rise, demand for normal goods typically increases, shifting the demand curve to the right. Conversely, demand for inferior goods may decrease. Consumer preferences and tastes also play a significant role; a trend or fad can boost demand, while a decline in popularity can reduce it.

Furthermore, the prices of related goods can influence demand. If the price of a substitute good rises, the demand for the original good will likely increase as consumers switch. Conversely, an increase in the price of a complementary good, one that is often used together with the original good, will tend to decrease the demand for the original good.

Expectations about future prices or income can also cause a keresletváltozás. If consumers anticipate a price increase, they may buy more now, shifting demand to the right. Similarly, expectations of future income gains can lead to increased current demand. Finally, the number of buyers in the market is a direct determinant of aggregate demand; an increase in the population or market size will generally increase demand. These shifts in demand have important implications for market equilibrium, influencing both price and quantity traded.
