# Hakekat Ilmu Ekonomi sebagai Ilmu yang Mempelajari Upaya Manusia dalam Memenuhi Kebutuhan Hidupnya ## A. Pengertian Ilmu Ekonomi * The term "economics" was first coined by Xenophon (430-355 BC). * Economics comes from the Greek word "Oikonomia", meaning “household management” or “rule of the house”. * In a narrow sense, economics is the rules of household management, while in a broader sense, it is the study of how people meet their needs. * According to Paul A. Samuelson (American Economist), economics is the study of how individuals and societies make choices under conditions of scarcity. * The basic principles that form the foundation of economics are: 1. Scarcity 2. Choice ## B. Branches of Economics * Based on scope/range, economics can be divided into three branches: 1. **Descriptive Economics**: This branch of economics describes economic phenomena in a society using tables, graphs, and charts. 2. **Economic Theory**: This branch analyzes the relationship between economic events to formulate theories or laws of economics. Examples include the law of demand and the law of supply. * Economic theory can be further divided into: * **Microeconomics**: This branch studies the behavior of individual economic units like consumers, producers, and markets. * **Macroeconomics**: This branch studies the economy as a whole, focusing on issues like national income, employment, inflation, and economic growth. 3. **Applied Economics**: This branch uses economic theory to solve real-world economic problems. It focuses on practical applications of economic principles. ## C. Benefits of Studying Economics * Economics can help individuals and businesses prioritize their needs. * Economics can help understand human behavior in fulfilling limited needs with limited resources. * Economics can help choose the most efficient and effective way to use resources. * Economics can help allocate scarce natural resources. * Economics can help understand global issues. * Economics can teach people to manage their finances effectively. * Economics can develop individuals to be socially conscious, precise, and economical in their approach. ## II. Economic Activities * There are three main economic activities in society: 1. **Production**: Converting raw materials into finished goods. This process increases a good's utility. People involved in this process are called producers. * Factors of production: * **Land**: Natural resources such as land, water, air, and minerals. * **Labor**: Human effort that contributes to the production process. * **Capital**: Goods used in the production of other goods. * **Entrepreneurship**: The ability to combine the other inputs to create a product or service. * Objectives of production: * Profit maximization * Fulfilling societal needs 2. **Distribution**: The process of transferring finished goods from producers to consumers. The individuals or organizations involved are called distributors. * Types of distribution: * **Direct distribution**: Goods flow directly from the producer to the consumer. * **Semi-direct distribution**: An intermediary helps connect the producer and consumer. * **Indirect distribution**: Several intermediaries between the producer and consumer handle the distribution. * Factors affecting distribution: * Type of goods: Durable or non-durable goods. * Market location: Proximity to the target market. * Producer's financial capacity: Ability to finance distribution channels. 3. **Consumption**: Using goods and services to satisfy wants and needs. Individuals involved are called consumers. * Factors affecting consumption: * Price of goods * Income * Consumer preferences * Price of related goods * Size of the household ## III. Needs ### A.

Definition of Scarcity * Scarcity refers to the fundamental economic problem of having unlimited wants and needs but limited resources to satisfy them. ### B. Factors Affecting Scarcity * **Natural resource limitations:** Earth has finite natural resources to meet all human needs. * **Human limitations:** Limited human capabilities and skills restrict production efficiency. * **Capital limitations**: Limited resources for investment lead to fewer opportunities. * **Technological limitations:** Limited technological advancements hinder production efficiency. ### C. Dealing with Scarcity * Prioritize needs. * Utilize resources efficiently. * Explore new resources. * Manage finances effectively. ## V. Economic Principles * Economic principles provide guidelines for making rational economic decisions. * These principles help individuals and businesses make optimal choices to maximize value and minimize costs. * Key economic principles include: * **Scarcity:** Understanding that resources are limited. * **Choice:** Making decisions based on trade-offs and opportunity costs. * **Rationality:** Making decisions based on logical cost-benefit analysis. * **Incentives:** Responding to rewards and penalties associated with choices. ## VI. Economic Motives * Economic motives are the driving forces behind economic actions. * Motives can be intrinsic or extrinsic. * **Intrinsic motives:** Internal motivations like personal satisfaction, growth, or self-achievement. * **Extrinsic motives:** External motivations like financial gain, social status, or recognition. * Major Economic Motives: * **Meeting needs and wants:** Driving force for production and consumption. * **Profit maximization**: Seeking to increase income and revenue. * **Power:** Obtaining control and influence in economic activities. * **Social responsibility:** Contributing to the well-being of society and the environment. * **Personal fulfillment:** Finding meaning and satisfaction in one's economic endeavors. The study of economics offers insights into how individuals and societies respond to scarcity. Understanding economic principles and motives provides individuals and businesses with a framework for making rational decisions and contributing to economic development.
