1.4. Positive and Normative Economics

It was mentioned earlier that in principle there are more than one ways of solving the central problems of an economy. These different mechanisms in general are likely to give rise to different solutions to those problems, thereby resulting in different allocations of the resources and also different distributions of the final mix of goods and services produced in the economy.

In economics, there are various approaches to solve an economy's central problems. Each approach can lead to different outcomes, such as how resources are allocated and how goods and services are distributed among people. Understanding these different approaches helps economists determine which method might work best for the economy as a whole.

Think of it like choosing how to bake a cake. You can use different recipes (mechanisms) that might use different ingredients (resources) to create cakes with various flavors (outcomes). Some recipes might call for chocolate, while others might use vanilla, leading to different cakes but all aiming to satisfy the same need for dessert.

In positive economic analysis, we study how the different mechanisms function.

Positive economics focuses on understanding how the economic systems work without making judgments about whether the outcomes are good or bad. It aims to describe and predict economic phenomena, such as how changes in pricing will affect supply and demand.

Consider a scientist observing a chemical reaction in a lab. They describe the process as it happens, noting how certain chemicals react with one another without stating whether the reaction is good or harmful. Similarly, positive economics simply describes economic behaviors and outcomes.

In normative economics, we try to understand whether these mechanisms are desirable or not.

Normative economics evaluates the outcomes of different economic mechanisms to determine if they are good or desirable for society. It involves judgments about what should be done to improve economic welfare and the distribution of wealth and resources.

Imagine a teacher assessing student performance. They not only describe what a student has achieved (positive) but also suggest ways to improve their learning (normative). Normative economics similarly suggests improvements or changes based on the outcomes of different economic practices.

However, this distinction between positive and normative economic analysis is not a very sharp one. The positive and the normative issues involved in the study of the central economic problems are very closely related to each other and a proper understanding of one is not possible in isolation to the other.

The line between positive and normative economics can blur because understanding how an economic mechanism works (positive) often informs whether its outcomes are desirable (normative). Both analyses can influence each other, as evaluating outcomes can lead to new insights about how to improve economic mechanisms.

Consider a doctor diagnosing a health condition (positive) and then recommending treatments (normative). The diagnosis provides necessary information that is crucial for determining the best treatment options, demonstrating how one informs the other.
