Explain how a surplus of a product, such as strawberries, can lead to both financial losses for farmers and food wastage.

A surplus of strawberries drives down prices, diminishing farmers' revenue and potentially causing financial losses. At the same time, the excess supply can make it difficult for farmers to sell all of their produce before it spoils, leading to wasted strawberries. Signup and view all the answers

Study Notes

Demand and Supply

Black Friday is a time when consumers are eager to buy new products, like sneakers, at affordable prices
Consumers are closely monitoring product prices to determine if they can afford products within their budget
The announcements of Black Friday sales create buzz and market interest, influencing competitors' pricing strategies
Price and quantity of goods and services are determined by demand and supply
Demand is the value consumers place on goods and services they are willing and able to purchase
Supply is the willingness and ability of producers to sell goods and services
Demand is inversely related to price; as price increases, quantity demanded decreases
Law of demand states that as product prices increase, the quantity demanded decreases, and vice versa
The law of demand shows an inverse relationship between price and quantity demanded
This relationship can be shown in a demand function (Qd = a - bP) and a demand schedule
Qd = quantity demanded
a= all factors other than price that affect demand (ex. income)
b= slope of the demand curve
P = Price of the good
Supply is directly related to price; as price increases, the quantity supplied increases
Law of supply states that as the price of a product increases the quantity supplied by producers also increases; and vice versa
This positive relationship between price and quantity supplied can be shown in a supply function (Qs = c + dP)
Qs = quantity supplied
c = plots the start point of the supply curve, typically on the Y-axis
d = slope of the supply curve
P = Price of the good
Market equilibrium occurs when quantity demanded (Qd) equals quantity supplied (Qs).
Equilibrium price is the price at which Qd and Qs are equal.
Equilibrium quantity is the quantity at which Qd and Qs are equal.
Graphs can be used to graphically depict the relationship between price and quantity for demand and supply
Supply and demand curves visually represent the relationship between price and quantity on a graph for a particular market.

Factors Affecting Demand

Consumer income: higher income leads to higher demand for normal goods
Prices of related goods (substitutes and complements): increases in substitute prices increase demand, and increased prices of complements decrease demand

Factors Affecting Supply

Prices of inputs: rise in input prices decrease supply
Number of Firms: more sellers in a market lead to higher competition, and prices tend to fall
Expectations of future prices: future price increases cause decrease in present supply
Technology: advancements typically lead to increases in supply
