UNIT 1
Market Reactions to Events
Prices do not react immediately to market-changing events.
Changes in prices may precede actual events due to various factors.
Anticipation in Price Changes
Prices might rise or fall before the market-changing event.
Example of how anticipation causes price fluctuations:
After a hurricane, prices of tinned items typically increase.
Hypothetical scenario:
Anticipation of a storm at sea making landfall leads consumers to buy tinned items before prices increase.
As more consumers act on anticipation, scarcity of these items increases before the storm actually hits.
Anticipation Explained
Buyers who anticipate supply reductions stock up before the event, causing immediate scarcity, which then stimulates price increases.
This phenomenon is observed in multiple markets, such as:
Oil market: Prices rise with threats of military action or political instability in the Middle East, where according to historical data, the region accounts for about 50% of global oil supply.
Delayed Price Changes
Labor Market as an Example
Price changes may be delayed after market events occur.
Labor market characteristics:
Employees are suppliers of labor, while businesses are the demanders.
Example:
Sudden falloff in economic activity reduces demand for labor, which should theoretically lower wages.
However, wage changes do not happen instantaneously due to fixed contracts.
Workers sign contracts that may extend for years, hindering immediate wage adjustments.
Price Controls
Government Intervention
Governments may implement price controls that hinder price adjustments.
Example of price ceiling:
Government caps bread prices at $400 when market price is $650.
The impact of price ceilings:
Market forces ultimately drive prices; sellers may use alternative methods to effect price increases.
Examples include reducing product quantities while maintaining price (shrinkflation) and reducing quality without altering price.
Strategies to Counter Price Controls
Selling underpriced goods in bundle deals with overpriced items is a typical market response to maintain margins, known as "marrying" products.
Example of a retailer bundling bread with an overpriced item like jam to recover profit margins after the price ceiling enactment.
Scarcity and Surpluses
Understanding Shortages and Prices
Shortages occur when demand exceeds supply, resulting in price increases.
Surpluses occur when supply exceeds demand, causing prices to decrease.
However, price changes may lag in response to these imbalances.
Price Gouging and Responses
Price gouging accusations arise post-natural disasters, such as hurricanes, where sellers raise prices.
This often occurs in response to actual scarcity of products like food and water.
Example from 2021:
A glut in tomatoes led to excess supply, resulting in lower prices, negatively impacting tomato farmers financially.
One suggested remedy is converting surplus tomatoes into products such as sauces at a processing facility.
Foundational Economic Principles
Principle of Diminishing Returns
Each additional input incrementally provides less output over time.
Example to illustrate this principle:
An individual (John) consuming multiple cans of a product (supplicant) experiences diminishing satisfaction with each additional can consumed.
Economic Application of Diminishing Returns
It applies to production, where the addition of inputs without varying others leads to decreasing marginal products.
Example:
A farmer hires workers to produce wheat:
The first worker might yield 10 bushels, the second 8, the third only 5, and so forth.
In production settings, at some point, additional workers may become less productive due to limited equipment or space.
Marginal Product Defined
Marginal product: the increase in output resulting from using an additional unit of an input while keeping all other inputs constant.
Law of diminishing returns highlights that non-variable inputs lead to declining marginal productivity in the face of excess additional inputs.
Interconnection of Markets
Case Study of Coffee and Alternatives
Economic interconnection is evident when market conditions in one sector affect another.
Example with Brazil's coffee:
A disruption in Brazil's coffee supply raises prices, leading consumers to seek alternatives like tea.
Increased demand for tea encourages farmers to allocate more resources towards tea production, reducing rubber production, thus raising rubber prices as well.
Summary of Market Interconnections
All markets are interlinked, and shifts in one market's prices will influence others, demonstrating the interconnected nature of global economies.
The principle of supply and demand acts as a signaling mechanism to guide those changes, often referred to by Adam Smith as the "invisible hand" of the marketplace.
