1. Positive Economics
● What it is: Positive economics focuses on
describing and explaining economic phenomena as they exist in the real world.
It deals with facts, data, and cause-and-effect relationships. The key here is
objectivity; positive economic statements can be tested and either proven or
disproven using empirical evidence.
●Measurable and Testable: The beauty of positive economics lies
in its measurability. Economists can gather data, conduct experiments, and use
statistical analysis to verify or refute their hypotheses. For example, they
might examine the impact of a tax cut on consumer spending by analyzing sales
data before and after the tax cut.
● Example: The statement "An increase in the
minimum wage leads to higher unemployment" is a positive economic
statement. It doesn't express an opinion on whether raising the minimum wage is
good or bad; it simply states a potential relationship between two variables
that can be investigated through data.
2. Normative Economics
● What it is: Normative economics is concerned with
what "should" be in the economy. It involves making value judgments
and recommendations about economic policies. It's inherently subjective, as
different people and societies may have different values and priorities.
●Subjective and Value-Laden: Normative economic statements cannot be
definitively proven or disproven because they are based on opinions and
beliefs. For instance, the statement "The government should provide
universal healthcare" is a normative statement. It reflects a particular
viewpoint on the role of government and the importance of healthcare access.
● Requires Societal Debate: Normative economics often sparks
debates and discussions about the best course of action for society. Different
stakeholders, including citizens, politicians, and economists, may have
conflicting views on what constitutes a fair and just economic system.
● Examples: Questions like "Should the
government increase taxes on the wealthy?" or "Should we prioritize
environmental protection over economic growth?" fall under the realm of
normative economics. They require weighing different values and considering the
potential consequences of different policy choices.
3. Descriptive Economics
● What it is: Descriptive economics serves as the
foundation for economic theory. It involves observing and collecting data on
economic activities and behaviors in the real world. Economists then use this
data to develop theories and models that explain how the economy works.
● Building Economic Theory: Descriptive economics is the starting
point for formulating economic theories. By observing patterns and trends in
economic data, economists can develop generalizations about how individuals and
businesses make decisions. These theories help us understand the underlying
mechanisms of the economy.
● Assumptions and Simplifications: Economic theories often rely on
simplifying assumptions about human behavior, such as the assumption of
rational self-interest. While these assumptions may not perfectly reflect
reality, they allow economists to create models and theories that are manageable
and provide valuable insights.
● Example: The law of demand, which states that as
the price of a good increases, the quantity demanded decreases, is an example
of an economic theory based on descriptive economics. Economists have observed
this pattern consistently in various markets, leading to the formulation of
this fundamental principle.
Economic Theory, Economic
Policy, and Economic Models: Tools for Exploring the Economic World
1. Economic Theory: The Compass in the Economic World
We all know that to reach a
new destination, we need a map or a compass for guidance. In the vast and
complex world of economics, economic theory is the compass that helps us find
the right direction.
● From Observation to Theory: Economists are not merely people who
sit in research rooms and come up with hypotheses. They are keen observers of
the world around them, from the daily shopping decisions of consumers to the
business strategies of large corporations. From these real-world observations,
they deduce general rules and basic principles about how the economy works.
That is economic theory.
● The Practicality of Economic Theory: One of the appealing aspects of
economic theory is its practicality. Economic theories are not just dry
mathematical formulas; they reflect what is happening in the real world. For
example, the theory of supply and demand explains why prices of goods change
over time, or the theory of comparative advantage helps us understand why
countries trade with each other.
● Economic Behavior and Choice: People are at the center of economic
activities, and economic theory helps us understand the motivations and ways in
which people make economic decisions. From choosing to buy a new phone or save
money for the future, to a business deciding whether to invest in a new
project, everything involves weighing benefits and costs, and considering
different options.
2. Economic Policy: From Theory to Action
If economic theory is the
guiding compass, then economic policy is the concrete steps that help us move
forward.
● Tools to Change the World: Governments have many powerful tools to
influence the economy. From adjusting interest rates to control inflation, to
investing in education to improve the quality of human resources, or enacting
regulations to protect the environment, all are examples of economic policy.
● Choices and Trade-offs: Making economic policy decisions is not
simple. Each policy has its own advantages and disadvantages and often involves
trade-offs between different goals. For example, raising taxes can help the
government have more revenue to invest in important areas, but at the same
time, it can also reduce people's purchasing power and hinder economic growth.
● Vision and Values: Economic policy is not merely the
mechanical application of economic tools. It also reflects the vision and
values of a society. For example, a society that values social justice may
prioritize policies that support the poor and reduce inequality, while a
society that values economic freedom may focus on minimizing government
intervention in the market.
3. Economic Models: Simplified Maps of the Economic World
Just like a map helps us
visualize a vast land, economic models help us have an overview of the economy,
thereby making more accurate forecasts and analyses.
● From Complex to Simple: The real economy is an extremely
complex system, with millions of individuals and businesses interacting with
each other. Economic models help us simplify this system by focusing on the
most important factors and eliminating unnecessary details.
● The Power of Assumptions: To build an economic model, economists
have to make certain assumptions. Although these assumptions may not fully
reflect reality, they help us create a model simple enough to understand and
analyze.
● Forecasting and Analysis: Economic models not only help us
understand how the current economy works but also allow us to forecast future
changes. For example, an economic model can help us predict the impact of an
interest rate increase on inflation and economic growth.
In Conclusion
Economic
methodology provides a framework for understanding and analyzing the complex
world of economics. Positive economics focuses on objective analysis and
empirical evidence, while normative economics deals with subjective value
judgments and policy recommendations. Descriptive economics serves as the
bridge between the real world and economic theory, leading to the development
of models and theories that explain economic behavior. Economic policies are
the practical applications of economic theories, reflecting societal values and
priorities. Economic models, such as the Production Possibility Curve, help
simplify complex economic systems and provide insights into trade-offs and
choices. By understanding these concepts, we can gain a deeper appreciation for
the intricacies of the economic world and make more informed decisions in our
personal and professional lives.
