Market Dynamics: Competition, Supply, and Demand

Posted on Dec 8, 2024 in Economy

Characteristics of Market Lambs

  • Homogeneity: If the consumer goes down in price or other aspects, it can be different. Now, the specific characteristics can be objective or subjective.
  • Perfect Information: If the consumer knows all the characteristics and conditions, and the company that offers them is uniform, it is easier to have perfect information. We look only at the price.
  • Entry Barriers: Obstacles that exist to dedicate oneself to some activity (legal barriers, capital, a very prestigious company, exclusivity, companies producing low-cost bivalve).
  • No Bidding: If there is little or a lot of competition, barriers mean more companies offer the good. In a perfectly competitive market, stay informed, be consistent, no barriers, and many companies.



Demand

Consumers. Characteristics: Demand depends on:

  1. Price of a good: When a lamb is expensive, people purchase less and vice-versa.
    • Substitution effect: People will buy goods that look like the ones whose rates have not risen (perfect information and consistency).
    • Income effect: If a lamb goes up in price, and its consumer can not afford it, they will stop consuming it or decrease consumption.
  2. Consumer income: If you have more money, you will want to buy more.
  3. Consumer expectations: If they are optimistic, they will buy more goods. Price expectations: If they think the price of the asset will increase, they will want to buy more before.
  4. Other goods’ prices: If goods are complementary, if the price of one of them goes up, people buy more of the other.
  5. A change in population: If the population increases, there will be more people to buy.
  6. Consumer tastes: If a lamb becomes fashionable, people will buy more.



Demand Function

Relationship between the amount buyers want to buy and its price. It is decreasing; when the price is higher, the quantity is much lower.

  • Movement of the curve: When the price goes down, the quantity goes up, and vice-versa.
  • Displacement of the curve: The curve changes for any reason other than money.



Supply

What companies offer, charge a fee for this, and have a production cost. The objective is to achieve the greatest gain. The supply of lambs depends on:

  1. The price: When the price increases, the supply also increases because new companies enter the market, attracted by the high price that makes production profitable. But the price falls when there are many companies offering the good.
  2. Price of inputs used: The company. If the factors are expensive, costs will increase, and the administration will sell more expensively, and vice-versa.
  3. Technological and organizational level: Improvement so companies can offer cheaper production.
  4. Price of similar goods.
  5. Company strategies: Sales, wanting to increase even if they earn less.
  6. Factors/laws: Legal barriers restricting the actions of companies.
  7. Maximum production capacity: Companies have limited resources, and the amount of some of them cannot be changed quickly.



Supply Function

Relationship between the price and quantity that is offered. It grows; when the price varies, the quantity does the same way because companies earn more money or lose less.

Market Balance

The price situation in which the quantity offered is equal to demand, the market tends to achieve it. If the price is below equilibrium, consumers seek more quantity and start to pay higher prices. In this way, some companies stop offering this good, and some consumers stop wanting to buy it because it is expensive. The price will go up to the equilibrium level, and they will sell just what is needed.

  • Shortage: Demand is greater than supply.
  • Surplus: Supply is greater than demand.


Balance and Price Control

  1. Maximum price: Established to avoid prices being too high and people not being able to pay. If the maximum price is below equilibrium, there will be a shortage; more people will buy than the quantity offered.
  2. Minimum prices: Established to ensure manufacturing companies a minimum income; it is the minimum guaranteed price. If the price is above equilibrium, there will be a permanent surplus, and equilibrium cannot be reached.



External Sector

  1. Imports: Consumers buy from foreign companies in a country.
  2. Exports: Companies in a country sell to foreign countries.
  • The difference between the monetary value of all goods exported and imported in a country is called the balance of trade. If imports are larger than exports, we say the country has a trade deficit, and if it is the other way around, it has a surplus.



Imperfect Competition

A type of market where there is a lack of the four characteristics of perfect competition.

Monopoly

There is only one company that offers the good.

Causes
  1. Entry barriers:
    • High capital needs
    • Legal constraints on the entry of competitors: The government determines that some lambs may only be offered by one company (e.g., RENFE).
    • Sole control of a factor or resource
    • Cost advantage: When a company can produce much cheaper than other competitors, it can eliminate them. Sometimes there is only one company that offers a lamb because of high fixed costs (e.g., electricity).
  2. The good will be uniform, and the information perfect: The company can set the price it wants within its interests; it faces a decreasing demand.
  3. It is bad because: The company has market power; it can take advantage of its dominance and prevent the entry of competitors. It does not strive for maximum efficiency and satisfaction for its consumers.
  4. The government can intervene:
    1. Avoid the appearance of monopolies, eliminating entry barriers.
    2. Supervise and monitor the operation to prevent abuse (standards, higher taxes, setting prices, etc.).
    3. Divide the company into more than one to increase competition.
