1.2.7 Price Mechanism (Edexcel)


Last updated 19 Sept 2023

This study note for Edexcel covers the Price Mechanism

A) Functions of the Price Mechanism to Allocate Resources

1. Rationing Function

  • Prices act as a rationing mechanism to allocate scarce resources among competing uses.
  • When demand exceeds supply, prices rise, discouraging some consumers from buying, and ensuring that goods are allocated to those willing to pay the highest prices.

Example: During a natural disaster, like a hurricane, there may be a shortage of essential supplies like bottled water. As prices rise due to increased demand, those in urgent need may be willing to pay more, while others may reduce their consumption, allowing resources to go where they are most needed.

2. Incentive Function

  • Prices provide incentives for producers to allocate resources efficiently.
  • Higher prices indicate increased demand, motivating producers to produce more of a particular good or service.
  • Lower prices signal decreased demand, encouraging producers to reallocate resources to more profitable uses.

Example: If the price of crude oil rises significantly, oil-producing countries have a greater incentive to increase production as they can earn higher revenues. This can lead to increased oil supply in the market.

3. Signaling Function

  • Prices convey information about changing market conditions, allowing consumers and producers to make informed decisions.
  • Rising prices may signal potential shortages, prompting consumers to conserve and producers to increase supply.
  • Falling prices may indicate oversupply, prompting consumers to buy more and producers to cut back on production.

Example: The fluctuation of gasoline prices at the pump can signal changes in global oil markets. If prices rise, consumers may consider carpooling or using public transportation, while oil companies may invest more in exploration and production.

B) The Price Mechanism in Different Types of Markets

1. Local Markets

  • In local markets, prices are determined by supply and demand conditions within a specific geographic area.
  • Local factors, such as weather or local preferences, can influence prices.
  • Example: The price of fresh produce at a local farmers' market may vary based on seasonal factors and local supply.

2. National Markets

  • National markets cover an entire country and consider supply and demand at a broader scale.
  • National policies and regulations, such as taxes and trade policies, can impact prices.
  • Example: The national housing market may be influenced by government policies related to interest rates and mortgage regulations.

3. Global Markets

  • Global markets involve international trade and can be influenced by factors like currency exchange rates, global supply chains, and geopolitical events.
  • Prices in global markets are interconnected and can impact local and national markets.
  • Example: The price of oil in global markets affects fuel prices around the world, impacting consumers and industries in various countries.

Numerical Example:

  • Consider a global market for smartphones. A new model is released, and its price is initially high due to high demand and limited supply. As production ramps up, the price gradually decreases. This price adjustment signals to consumers that the product is becoming more affordable, incentivizing them to purchase. Over time, as competition increases and new models are released, the price may continue to fall, leading to efficient allocation of resources and innovation in the industry.

Understanding the functions of the price mechanism and its role in different types of markets is crucial for analyzing how resources are allocated, responding to changing market conditions, and making informed economic decisions at the local, national, and global levels.
