Supply changes shift demand for market equilibrium

 Quantity supplied brings a shift in the demand curve against changes to keep the market in equilibrium

It's important to note that the quantity supplied is typically a response to changes in a good or service price, rather than a direct cause of shifts in the demand curve. The demand curve shows the relationship between the quantity demanded and the price of a good, while the supply curve reflects the relationship between the quantity supplied and the price.

However, if we consider a scenario where the quantity supplied indirectly affects the demand curve, we might think about the concept of feedback loops or dynamic adjustments in a market:

Increase in Quantity Supplied:

If producers increase the quantity supplied (perhaps due to improved technology or increased resources), this could lead to a temporary oversupply in the market.

The oversupply might put downward pressure on prices, causing consumers to respond by buying more, thus potentially increasing overall demand.

Over time, this increased demand could contribute to a shift in the demand curve to the right as consumers' preferences and expectations adjust.

 Decrease in Quantity Supplied:

Conversely, if producers reduce the quantity supplied (due to factors like increased production costs), there might be a temporary shortage in the market.

The shortage could result in higher prices, leading consumers to buy less, potentially decreasing overall demand.

Over time, this decreased demand could contribute to a shift in the demand curve to the left as consumers adjust their preferences.

It's crucial to understand that these processes are complex, and changes in quantity supplied usually affect prices and, subsequently, consumer behavior. The demand curve may then shift over time in response to these changes. Additionally, other factors, such as consumer income, preferences, and expectations, can also influence demand curve shifts.

In summary, while changes in quantity supplied may indirectly influence the demand curve over time through price adjustments and consumer responses, the direct relationship is between quantity supplied and price and between quantity demanded and price
