Methodology of Positive Economics: Model Building and Theorization

Theories in economics do not appear out of nowhere. They are the result of a thorough scientific examination of economic processes. This approach entails close observation, thorough data collection, and analysis to establish correlations between economic factors. When these linkages have been adequately validated, they are formalised as theories or hypotheses, a process known as theorization.

In addition, model building is an important part of the scientific method of inquiry. An analytical model distils a real-world economic occurrence, making reality more understandable. Economic models are mathematical equations that describe how economic factors interact. They are important tools for deducing the implications of economic theories and formulating forecasts. This will enable us to create more effective and inclusive approaches to addressing complicated economic concerns.

Model Building and Economic Theorization

The following steps are how the scientific method of inquiry is carried out in sequence:

1. Specifying the problem: It commences with defining the economic phenomenon under scrutiny. For instance, the effect of petrol price hikes on car demand or the causes behind a surge in onion prices and its impact on food inflation.

2. Formulating hypotheses: This involves articulating statements or equations that elucidate cause-and-effect relationships. For instance, an increase in gasoline prices leads to a decrease in car demand.

3. Making Assumptions: Assumptions are indispensable for simplifying complexities and isolating variables under scrutiny. These assumptions span behavioural, institutional, technological, and input-related realms.

4. Building a Relevant Model: A model is constructed to test the hypotheses, specifying the relationship between the chosen variables either mathematically or verbally.

5. Collection and Analysis of Relevant Data: Relevant data is gathered and analysed according to the model constructed, guiding the deduction of conclusions.

6. Testing the Validity of the Model: The model's validity is scrutinised through its predictive power. If the model accurately forecasts outcomes, it is deemed valid.

7. Formulation of the Theory: Finally, the findings are encapsulated in the form of a theory, offering insights into economic phenomena.

Uses and Limitations of Microeconomic Theories

While microeconomic theories provide useful analytical frameworks, they are not without limitations. These limitations derive from the assumptions on which they are based. Some significant limitations include:

1. Assumption of Static Macroeconomic Variables: Microeconomic theories assume constant macroeconomic variables, which diverge from real-world dynamism.

2. Assumption of a Free Enterprise System:
In reality, government interventions are prevalent, limiting the applicability of microeconomic theories.

3. Partial Analysis: Microeconomics solely analyses individual economic elements rather than the entire economic system, thus providing only a partial understanding.

Yet, these limitations do not diminish the importance of microeconomic theories. They offer a structured approach to understanding economic challenges, aiding in decision-making, policy formulation, and resource allocation.

The Uses of Microeconomic Theories

Regardless of their limitations, microeconomic theories provide invaluable perspectives on economic behaviour and decision-making. Here are some of the major applications:

1. Understanding Economic Dynamics: Microeconomic theories provide a structured framework for comprehending the complexities of economic systems. By distilling real-world phenomena into simplified models, they facilitate a clearer understanding of economic behaviour and interactions.

2. Predictive Analysis: These theories establish causal relationships between economic variables, enabling predictions about future economic trends and outcomes. This predictive capacity aids individuals, businesses, and policymakers in planning and decision-making.

3. Policy Formulation: Microeconomic theories serve as guiding principles for formulating effective economic policies. By analysing the implications of alternative policies, policymakers can make informed decisions to address economic challenges and promote economic welfare.

4. Business Decision-making: In the business realm, microeconomic theories offer valuable insights for decision-makers. By providing analytical tools and frameworks, these theories assist businesses in forecasting market trends, optimising resource allocation, and formulating strategic plans.

5. Optimal Resource Allocation: Microeconomic theories provide guidelines for optimising resource allocation, ensuring efficient utilisation of scarce resources. By identifying inefficiencies and market distortions, these theories help in achieving allocative efficiency and maximising social welfare.

Limitations of microeconomic theories

Despite their utility, microeconomic theories have certain limitations that warrant consideration:

1. Assumptions and Simplifications: Microeconomic theories often rely on simplifying assumptions, which may not accurately reflect real-world complexities. These assumptions can limit the applicability of theories to specific contexts and conditions.

2. Partial Analysis: Microeconomic theories focus on individual economic agents and markets, neglecting systemic interactions and interdependencies. This partial analysis may overlook broader economic phenomena and systemic risks.

3. Dynamic Nature of the Economy: The economy is dynamic and subject to constant change. Microeconomic theories, based on static assumptions, may fail to capture the evolving nature of economic phenomena and behaviours.

4. Government Interventions: Microeconomic theories assume a free-market environment, overlooking the role of government interventions and regulations. In reality, government policies often shape economic outcomes, complicating the application of microeconomic theories.


Microeconomics is a significant field of study with numerous justifications for its application. Liebhafsky highlights the influence of price theory, which is widely applied in economic analysis to categorise and organise economic activities and magnitudes. Marshall highlights the intrinsic motivation of individuals to understand and manipulate human behaviour, whether self-interested or altruistic. The primary objective of economic analysis is to provide a logical structure for economic reasoning, not to provide an impregnable solution but to provide a methodical framework for addressing challenges.

Economic principles and laws serve numerous practical functions in our daily existence, such as providing reasoning and instruments to forecast economic outcomes, ensuring effective resource distribution, and serving as standards for efficiency measurement. They also guide the development of suitable public policies to regulate economic activities and promote societal goals. Despite its inherent limitations, microeconomic theory remains an essential tool for understanding, scrutinising, and influencing economic phenomena to achieve broader societal objectives.
