Essential Economic Concepts: Break-Even, Markets, and GDP
Break-Even Point
The point of coverage where there is neither profit nor loss.
- Fixed Costs (CF): Costs that do not vary according to the units produced.
- Variable Costs (CV): Costs that vary with the units produced.
Elasticity
Measures the sensitivity or degree of variation in the quantity demanded relative to changes in variables within the demand function.
Key distinction: Elastic goods have various replacement options, while inelastic goods have few or no substitutes.
Monopoly
Exists when there is a single vendor in the market.
Features:
- The government grants exclusive rights to provide goods or services to one company.
- A company controls all funding sources required to produce a good or service.
- Unit costs decrease as production volume increases.
Perfect Competition Market
- Large number of participants: Numerous bidders and applicants ensure no single entity influences the price.
- Homogeneous goods: Consumers are indifferent between offerings. Companies are anonymous, and there are no trademarks, patents, or distinguishing elements.
- Freedom of entry and exit: Low barriers to enter or leave the market.
- Market transparency: Buyers and sellers have full knowledge of traded prices.
In perfect competition, each producer must make decisions based on the market price.
Gross Domestic Product (GDP)
GDP represents the total value of final goods and services produced in an economy during a specific period.
Measurement Methods:
- Measure the value added at each activity produced in the country.
- Measure the total amount of added value produced in each activity.
- Measure the total revenue generated in each production activity.
Inflation
A continuous increase in the prices of all goods and services in an economy over time.
Types of Inflation:
- Excess Demand: Price growth driven by consumption exceeding the company's production capacity.
- Cost-Push Inflation: Price increases resulting from rising production costs.
- Structural Inflation: Arises from imbalances in specific sectors affecting particular goods.
Business Cycles
Fluctuations in total output or GDP accompanied by changes in key economic variables.
Phases:
- Depression: The lowest point of economic activity; low demand and minimal new investment.
- Expansion: An upswing characterized by increased demand and sales.
- Peak (Auge): The highest point, featuring full utilization of production factors.
- Contraction (Descendente): Declining profitability, lower output, reduced employment, and economic difficulties.
