Economics Demand and Supply Shifters

Study Notes

Demand Shifters (TIRES)

Taste and Preference of Consumers: Influenced by celebrity endorsements, brand reputation, and trends; examples include popularity of brands like Lululemon.
Income of Consumers: Changes in fiscal or monetary policies and minimum wage affect purchasing ability, determining whether consumers opt for off-brand or premium products.
Related Goods: Includes substitutes (e.g., alternative products) and complements (e.g., products that go together like hot dogs and buns, pens and paper).
Expectations of Future Price Changes: Anticipation of rising prices prompts consumers to make purchases sooner; for example, college education decisions based on expected future tuition hikes.
Size of Population/Market: Population decline, such as the situation in Syria due to war, negatively impacts market demand and production capacities, such as oil.

Supply Shifters (TIGERS)

Technology: Technological advancements typically lead to increased supply; for instance, the cotton gin boosted cotton production, while the complexity of producing advanced technology like new iPhones can slow supply increases.
Inputs (Natural Resources): The availability of raw materials directly affects supply; for example, the difference in supply potential between mined and lab-grown diamonds is critical.
Government Intervention, International Events, and Disasters: Natural disasters can alter supply dynamics, such as in cases of sex trafficking rising in disaster-struck areas, indicating shifts in market conditions.
Expectations of Future Price Changes: Anticipation of price hikes encourages early spending; for instance, rising lumber prices lead to increased house prices, prompting consumers to buy now.
Related Goods and Resource Costs: Destruction of vanilla crops leads to increased prices and reduced supply among local creameries that rely on vanilla for their products.
Number of Sellers in the Market: An increase in sellers typically accompanies rising prices; conversely, a decrease in sellers occurs when prices fall, highlighting the responsive nature of supply to market prices.
