In economics, every choice involves a trade-off. Because resources like time and money are limited (a concept called scarcity), choosing one option means giving up the chance to pursue another. The opportunity cost is a fundamental concept that helps us understand the true cost of any decision.
Opportunity cost is defined as the value of the next best alternative that must be given up when making a choice. It's not just about the money spent; it's about what you could have had instead.
Consider the formula:
$Opportunity Cost = Value of the Next Best Alternative Forgone$
Let's look at why each option relates to the concept of opportunity cost:
This option accurately defines opportunity cost. When you choose to spend your Saturday studying, the opportunity cost is the value you place on the next best thing you could have done, like going to a movie with friends.
This describes a 'sunk cost'. Sunk costs are irrelevant to future decisions because they have already happened and cannot be changed. Opportunity cost, however, relates to future alternatives.
This is too broad. Opportunity cost specifically focuses on the *single next best* alternative, not the combined cost or value of every single option not chosen.
While the monetary cost is often part of the decision, opportunity cost isn't limited to money and isn't necessarily about the *most expensive* alternative, but rather the *most valuable* alternative that was given up.
Understanding opportunity cost is crucial for making rational decisions, both in personal life and in business. It highlights the hidden costs associated with any choice by focusing on the value of the best path not taken.
| Column A (Laws) | Column B (Descriptions) |
| A. Law of Demand | 1. After a certain point, increasing input leads to declining marginal product. |
| B. Law of Diminishing Marginal Product | 2. Demand and price move in opposite directions when income increases. |
| C. Law of Variable Proportions | 3. Marginal product initially rises with input usage, then falls. |
Which of the following statement is correct?
I. Indifference curves are sloping from left to right.
II. Higher indifference curve gives a higher level of utility.
If in a production process, all inputs are tripled, which of the following statements follows?
I. If the output is tripled, then decreasing returns to scale apply.
II. When the output is doubled, constant returns to scale apply.
III. If the output is more than tripled, then increasing returns to scale apply.
A market, in which there are a large number of firms, homogeneous product, infinite elasticity of demand for an individual firm and no control over price by firms, is termed as________.
If the two goods are substituted, then the indifference curve will be:
