Investment - Demand and Supply
Properly functioning markets are vital to capitalism because the interaction of buyers and sellers determines the price and amount of a product or service exchanged. The structuring of markets is crucial in microeconomics.
Demand
Buyers desire a product, and sellers supply the product. Consumers buy things, such as vehicles, books, and furniture, from manufacturers and retailers who sell them in markets. These marketplaces can take the form of physical facilities, such as supermarkets or shops, or they might be virtual, internet-based markets, such as eBay or Amazon.
In certain markets, there is a single provider of a product or service, whereas in other markets, there are several companies providing the same or similar products or services. There may be only one regional power company producing electricity, for example, but multiple companies providing home insurance. How markets are arranged can affect how the enterprises engaged in these markets set pricing.
When economists refer to demand, they mean the desire for a product or service paired with the ability and willingness to pay a specific price for it. Consumers will want and pay for a product as long as the perceived advantage is greater than its cost or price.
The Law of Demand
It seems natural that if the price of a product goes higher, people will typically buy less of the product.
For instance, if the price of fuel rises, car owners will use their cars less and hence buy less fuel. The quantity desired of a product and its price are usually inversely connected, which is known as the law of demand.
The Demand Curve
The law of demand can be represented on a graph, with the amount demanded on the horizontal axis and the price of the product on the vertical axis. The curve that depicts the quantity demanded at different prices is the demand curve.

Shift in Demand Curve to the Right
If people’s tastes change and they cease like pizza as much, demand will shift to the left, suggesting that consumers would demand less of the product at a given price. The range of pricing for the product has not changed, but the quantity requested at each price has reduced.
The figure depicts how a change in a factor that has made the product more attractive alters the demand curve to the right from D to D1.
Now, we will take a deeper look at the primary elements that affect the demand curve.
Effect of Income on Demand
A change in demand for a product coming from a change in purchasing power is called the income effect.
For most items, which are called typical goods, if income improves, demand increases too. Meat is an example of a normal good in most emerging nations.
For lesser commodities, the relationship works in the reverse direction. That is, demand for lesser things diminishes as income increases. Grain is frequently regarded an inferior good. So, when incomes are higher, individuals consume more meat relative to grain.
Demand for poor products often grows during recessions. When faced with a time of downturn in economic activity, people prefer to move to lower-cost brands and purchase more at discount stores than at department stores. During such a period, investors may focus on companies that sell inferior goods because they expect their stocks to perform better.
Effect of the Expected Future Price of a Product on Demand
There is a positive association between the predicted future price of a product and its current demand. In other words, the predicted future price and current demand move in the same direction.
If consumers predict that the price of rice will increase as a result of a shortage, the current quantity of rice requested may grow as consumers accumulate it to avoid paying a higher price in the future.
The amount demanded at all prices will rise in anticipation of the price increase, resulting to a change in the demand curve to the right.
In contrast, if the price of a product is predicted to reduce in the future, present demand may go down as people wait for the price to decrease before purchasing.
Effect of Changes in General Tastes and Preferences on Demand
Changes in consumers’ likes and preferences might impact a product’s demand curve.
If a report that linked eating chocolate to greater health is published, demand for chocolate bars may soar.
In that circumstance, the demand curve for chocolate will shift to the right. Investors and analysts typically examine demographic changes and shifts in consumers’ interests and preferences when appraising an investment.
Effect of Prices of Other Products on Demand
As we observed earlier, if the price of sandwiches increases, individuals may eat more pizza instead. The influence of a change in the prices of other items on a product’s demand curve relies on the sort of link between the products.
Substitute Products
A substitute product or substitute might normally take the place of another product. For many customers, Coke and Pepsi are regarded reasonably close replacements. Consumers exchange relatively cheaper products for relatively more expensive ones. If the price of a substitute product lowers, demand for the alternative may increase and demand for the original product may decline.
Example: The Effect of a Change in Coke’s Price on the Demand for Coke and Pepsi
If the price of Coke lowers, there is likely to be an increase in demand for Coke and a decrease in demand for Pepsi.
If a bottle of Coke and Pepsi each sell for USD1, individuals will have no preference based on price. But if the Coca-Cola Company seeks to boost its market share, it might decrease — possibly just momentarily — the price of a bottle of Coke to 90 cents.
Although there will still be many faithful Pepsi fans, there will probably be a number of people who will buy Coke instead of Pepsi because it is now cheaper.
Coca-Cola expects that some of these people then develop a preference for Coke over Pepsi and become loyal Coke drinkers, and Coca-Cola may subsequently return its price to USD1.
Complementary products or complements are products that are frequently consumed together. When the price of a product lowers, it leads to an increase in demand for both the product and for its complimentary products.
For example, printing paper and ink cartridges are complementary products. If the price of ink cartridges lowers, consumers may print more and purchase both more ink cartridges and printing paper.
Demand for a given product may be altered by the prices of other products that are not replacements or complements. A big increase in oil prices sometimes causes demand for other products, including pizzas, to decline. The reason is that many people use automobiles to travel to work, school, or shopping, and they will have to pay more to put petrol in their cars if the price of oil rises. As a result, they will have less money to buy other things.
Psychology is typically engaged in decision making, which makes the effects of price changes on demand challenging to analyze. Because individuals commonly buy oil-related products, they constantly watch how the price of these things fluctuates, and they may consume less overall if oil prices climb. And yet, an increase in the price of cars, which has a greater effect on the household budget, may not lead to a fall in demand.
The explanation is that consumers tend to pay less attention to the price adjustments of things that they purchase infrequently. Evaluating these types of psychological aspects helps investors determine if, for instance, a pizza company may notice a decline in sales when oil costs increase.
Supply
The supply curve illustrates the quantity supplied at different prices. The law of supply states that when the price of a commodity increases, the amount supplied increases too. Thus, the supply curve is upward sloping from left to right. The law of supply and the supply curve are represented in the following exhibit. S and S1 are supply curves.

Thus, the supply curve is upward sloping from left to right. The law of supply and the supply curve are represented in the following exhibit. S and S1 are supply curves.
Supply Curve
Lower manufacturing costs, which may be the result of improvements in technology, cheaper raw materials or labour, or lower taxes, will result in higher supply for a given price. The supply curve will move to the right. Changes in the supply curve are of major interest to investors and analysts. A shift in the supply curve induced by greater or lower costs might alter the profits generated by a corporation. A car manufacturer facing increased steel prices may be willing to build fewer automobiles at a given price level, which affects the supply curve. Whether a corporation can pass on any cost increases to customers helps investors assess the company’s potential profits.
A corporation that cannot cover its costs and earn a profit at prices along particular regions of the supply curve would not supply products at those prices. Companies may perceive factors affecting the supply curve as transient and be ready to continue operating despite short-term losses. But if the discrepancy between sales and costs remains for extended periods, it can trigger corporate shutdowns and bankruptcy.
Many airlines have confronted this dilemma as their manufacturing expenses, such as the cost of fuel, increased.
Their capacity to hike fares was constrained since passengers may have selected an alternate airline or mode of travel.
Equally, they could not readily raise or reduce the number of seats on their planes. Some airlines have accrued enormous losses and been forced to declare bankruptcy.
