Study Notes

Economics

The discipline of economics studies market economies, assuming a well-functioning market economy with well-functioning systems of legislation, jurisdiction, and government.
Economics assumes that fundamental institutions (rules, norms, and laws) of a market economy are given but sometimes break down, necessitating a multidisciplinary approach.
Economics is a social science, and the economy is embedded into the society.

Methodology

Most economic processes can be measured and expressed by numbers, making mathematics the most important language of the discipline.
Myriads of models and econometric (statistical) methods have been developed to analyze economic issues.

Models

It’s important to understand the world around us to be able to form it according to our needs.
Models are abstractions used to “understand” observations or experience and to express principles that can be applied to different problems.
The power of a model stems from its simplicity and how it can capture the essence of the problem.
A model’s suitability depends on the purpose for which it’s used, and assumptions must be tailored to those purposes.

The Economy

The society as a system has numerous parts with different purposes, and the economic subsystem covers the production and distribution of goods and services.
Economics deals with the economic subsystem (the economy).
The broader (or substantive) meaning of economic activity is that goods and services are produced to meet the material needs of people.
The narrower (formal) meaning of economic activity is that actors make decisions to promote their own interests within limited options.

The Market Mechanism

In market economies, prices are determined by the simultaneous decisions of actors on both the supply and the demand sides.

The Market Economy

The market economy is an economic system where answers to the fundamental questions of economics are predominantly left to the market:
- What to produce?
- How to produce?
- How to allocate productive resources?
- How to distribute goods and services?

Social sciences are not natural sciences, and one cannot design experiments to verify or falsify theories.
In social sciences, people, enterprises, or governments are not molecules or atomic particles, and therefore, the degree of freedom of processes is higher than in nature.

Laws in Economics

While the law of demand, the law of supply, and the law of diminishing returns exist, they are not like laws in natural sciences: they don’t predict perfectly what will happen.
Laws in social sciences (as well as all models) are like “rules of thumb”, providing orientations on what to expect in different situations.

The Mainstream

Since no models can have exclusive vindication in social sciences, we must conform to the multiplicity of approaches.
Some models and approaches are more useful than others, have more predicting power, or explain situations more accurately, and are considered the mainstream.

Microeconomics & Macroeconomics

Economics has two main branches:
- Microeconomics deals with the behavior, incentives, and choices of different actors of the economy.
- Macroeconomics examines the functioning of the economy as a whole.
This course is an introduction to microeconomics.
