key term - Decrease in Supply

Definition

A decrease in supply occurs when the quantity of a good or service that producers are willing and able to sell at every price level decreases. This shift can lead to a higher equilibrium price and a lower quantity sold in the market, creating a new market situation that may lead to disequilibrium if demand remains unchanged. Factors such as increased production costs, government regulations, or natural disasters can trigger this decrease.

5 Must Know Facts For Your Next Test

1. A decrease in supply is represented by a leftward shift of the supply curve on a graph, indicating less quantity available at each price.
2. When there is a decrease in supply, consumers may face higher prices for goods and services due to the reduced availability.
3. External factors like increases in production costs, such as wages or raw materials, can cause a decrease in supply.
4. Government interventions, like new taxes or stricter regulations, can also lead to a decrease in supply by increasing costs for producers.
5. In markets experiencing a decrease in supply, producers may respond by increasing prices to maintain profitability amid lower output.

Review Questions

• How does a decrease in supply affect market equilibrium?
  • A decrease in supply causes the supply curve to shift leftward, leading to a higher equilibrium price and a lower equilibrium quantity sold in the market. As producers are willing to sell less at each price point, consumers will compete for the reduced quantity available, driving prices up. If demand remains constant while supply decreases, this change can create disequilibrium, leading to potential shortages.
• What are some potential causes of a decrease in supply, and how might these impact consumers?
  • Potential causes of a decrease in supply include rising production costs due to increased wages or material prices, government regulations such as new taxes or restrictions, and external shocks like natural disasters. These factors can restrict producers' ability to supply goods at previous levels. As a result, consumers may face higher prices and fewer choices, impacting their purchasing decisions and overall market satisfaction.
• Evaluate the long-term implications of a persistent decrease in supply on an industry and its consumers.
  • A persistent decrease in supply can lead to significant long-term changes within an industry. Producers may be forced to innovate or streamline operations to cope with higher costs and reduced output. This could result in industry consolidation as weaker firms exit the market. For consumers, prolonged decreases in supply typically lead to consistently higher prices and less product availability. In turn, this could shift consumer preferences towards substitutes or alternative markets, permanently altering consumption patterns.
