Introduction

In this tutorial, we will explore the concept of opportunity cost, its significance in economics, and how to calculate it. Understanding opportunity cost can help individuals and businesses make better decisions when faced with choices. This guide will provide you with definitions, examples, and practical applications of opportunity cost.

Step 1: Understand the Definition of Opportunity Cost

Opportunity cost refers to the value of the next best alternative that is foregone when making a choice. It is important to recognize that this cost isn't always measured in monetary terms. Key definitions include:

• Gregory Mankiw: Opportunity cost is everything sacrificed to obtain something else.
• Paul A. Samuelson and William D. Nordhaus: It is the value of the product (goods or services) that is lost as a result of a choice.
• Robert B. Ekelund, Jr. and Robert D. Tollison: It represents the economic resources used for a specific purpose, measured against the profits that could have been earned from an alternative choice.

Step 2: Identify Examples of Opportunity Cost

To grasp the concept better, consider these examples:

• Personal Example:

  • Suppose you have IDR 20,000,000. You can either travel to Bali or buy a motorcycle.
  • If you choose the motorcycle, your opportunity cost is the vacation in Bali, and vice versa.

• Professional Example:

  • After graduation, Aji has two job offers: a management position at PT XYZ and a marketing position at PT OPQ.
  • If Aji chooses PT XYZ, the opportunity cost is the potential earnings and experience from the marketing job.

• Business Example:

  • PT Widyatama has a commercial property that they can either rent out for IDR 250,000,000 per year or use as a warehouse.
  • Choosing to use it as a warehouse means they incur the opportunity cost of not earning rental income.

Step 3: Recognize the Characteristics of Opportunity Cost

Understanding the characteristics will aid in applying the concept effectively:

1. Opportunity cost is not solely financial; it can involve time, enjoyment, or future benefits.
2. There are multiple potential uses related to the benefits derived from choices.
3. Decisions regarding opportunity costs depend on the individual's or company's goals and circumstances.
4. Typically, opportunity costs relate to secondary or tertiary needs rather than primary ones.

Step 4: Understand the Benefits of Analyzing Opportunity Cost

Evaluating opportunity costs provides several advantages:

1. It opens up business opportunities and reduces risks.
2. It aids in calculating capital and investment strategies.
3. It simplifies prioritization in decision-making.
4. It helps in minimizing business expenses.

Step 5: Calculate Opportunity Cost

Calculating opportunity cost is straightforward. Follow these steps:

1. Identify Your Choices: Consider at least two alternatives.
2. Determine What You Will Give Up: Identify the option you will not choose.
3. Evaluate the Foregone Option: Assess the value or benefits of the alternative that you are not selecting.

Example Calculation

Using the earlier example of choosing between a motorcycle and a vacation:

• If the vacation is valued at IDR 25,000,000, the opportunity cost of purchasing the motorcycle is IDR 25,000,000.

Conclusion

Opportunity cost is a fundamental concept in economics that helps individuals and businesses make informed decisions. By understanding its definition, recognizing its examples, and learning how to calculate it, you can apply this knowledge to both personal and professional situations. Next, consider how opportunity costs might influence your decision-making in your life and work.
