Economic Basics and Market Functions
Economic statements can be either positive (factual, provable claims) or normative (value judgments about how things should be). In any economy, we classify goods as either capital goods (durable items used to produce other goods) or consumer goods (products used by consumers).
The concept of specialisation forms the foundation of modern economies. When workers focus on specific tasks, becoming experts in particular areas of production, it leads to greater efficiency and productivity. This division of labour has transformed how we produce goods and services.
Money serves several crucial functions in our economy. It works as a store of value, allowing people to save for future purchases. It also acts as a measure of value, a means of exchange, and enables deferred payment through credit systems.
Did you know? Consumer behaviour isn't always rational! People often make economic decisions based on habit, herd mentality, or emotional comfort rather than pure logic.
Understanding elasticity is essential for predicting market reactions. Price Elasticity of Demand (PED) measures how responsive quantity demanded is to price changes, while Income Elasticity of Demand (YED) measures response to income changes. For related products, Cross Elasticity of Demand shows how demand for one product responds to price changes in another product.
Economic systems range from command economies (government control) to free markets (driven by consumer choice). Both have strengths and weaknesses - command economies ensure basic necessities for all but may lack innovation, while free markets offer choice but might not provide equitable access to goods.
The price mechanism serves three key functions: rationing resources based on willingness to pay, providing incentives for production, and signalling to producers what to supply.
Market Efficiency and Government Intervention
When markets function efficiently, they create both consumer surplus (the difference between what consumers are willing to pay and what they actually pay) and producer surplus (the difference between what producers receive and their cost of supply). These surpluses represent economic value created by market transactions.
Governments can influence markets through various tools. Indirect taxes include ad valorem taxes (based on transaction value) and specific taxes (applied to each unit sold). Conversely, subsidies are payments to suppliers that reduce production costs.
Markets often generate externalities - costs or benefits that affect parties not directly involved in transactions. Negative externalities create social costs (like pollution), while positive externalities create social benefits (like education). These externalities represent a form of market failure.
Important concept: The free rider problem occurs when people can benefit from goods without paying for them - a key issue with public goods that are both non-excludable and non-rival in consumption.
To address market failures, governments employ various interventions. They might impose taxes on goods with negative externalities or provide subsidies for goods with positive externalities. For environmental issues, pollution permits create economic incentives for firms to reduce emissions through trading schemes.
Government regulation offers another approach to market failures. While often simpler to implement than market-based solutions, regulations may be less efficient. The most effective policy mix typically combines multiple approaches tailored to the specific market failure being addressed.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

Economics is the study of how societies manage scarce resources, balancing between theoretical principles and practical applications. It explores how economic systems function, how markets determine prices, and how government interventions affect outcomes in both the micro and macro environments.
