What is economics?
Origin - greek word 'oikou + nomos'
Think of the monthly income that your parents earn. Using this money, they have to cover many expenses such as food, clothing, rent, various bills and even save some money for future occasions. Your parents have to thus take care of your needs and wants from the limited income they earn. Similarly, a society needs to fulfill unlimited wants of people using limited resources. Economics in turn studies how efficiently society uses these scarce resources to produce goods and services that people need. Thus, the two important themes of economics are scarcity (of resources) and multiplicity (of wants).
What are the questions that economics tries to answer?
Every country has limited resources with which it has to decide what goods to produce, how to produce these goods and for whom to produce these goods. For example, each country has limited supplies of land, labour, technical knowledge, factories and money. When trying to satisfy its people's wants, the economy has to decide how to allocate these resources to various activities. How much land to allocate to agriculture? How many textile factories to set up? Should the government build houses for its people? These are some questions that economics tries to answer.

Economists generally use two main types of theoretical models – a static economy and a dynamic economy.
Static economy: is one in which normal economic activities (production, consumption, etc.) take place but there is no change in the size of the economy or in the level of national output, stock of capital, prices and employment. Such an economy is not realistic but is useful for theoretical analysis. Another feature is that the variables used in this analysis are in the same point of time. A static economy is therefore a timeless economy. The purpose of using such a model is to understand relationships between related variables under static conditions.
Dynamic economy: is one in which economic forces and factors are constantly changing. Such a model takes time into account and is therefore useful to predict the future course of an economy.
Some differences between the two are outlined below:
Static analysis is an abstraction from reality, and dynamic analysis is the study of the real world.
In static analysis, the variables are taken at a single point in time, whereas in dynamic analysis their movement across different time periods is known.
Static analysis is timeless, whereas in dynamic analysis, time is one of the variables considered.
In static analysis, basic economic conditions are known and taken as given, but in dynamic analysis they change over time.
Dynamic analysis is useful in making predictions (for e.g., about economic output), which static analysis does not allow.

How do economies answer the three fundamental questions?
Markets: Think of the word 'market'. You may immediately think of a vegetable market or a arts-and-crafts market. These are good examples, but in economics, the term market refers to a system where several buyers and sellers interact to determine prices to exchange goods and services, just like in a real market. In economics, however, the term market does not necessarily refer to an actual, physical place. It is merely a concept. The section below will make things clearer.
Buyers and sellers interact in a market and their interaction helps answer the three fundamental questions raised above. For example, when many consumers go to the supermarket and buy coffee instead of tea, they are expressing their desire for coffee and thus implicitly help producers decide that more coffee should be produced instead of tea. This answers the question of what to produce.
Now that producers are going to produce more coffee, they will determine the technique of production based on their profit goals and budget constraints. They can hire labourers to handpick the coffee beans and dry them by hand, or buy a machine to do this. They may find that a machine is faster and more efficient, so they invest in some machinery, thus deciding how to produce.
The coffee producers have bags of coffee powder lying in their godowns. Who will consume this coffee? Again, the answer is in the market mechanism. It may be the case that Bangaloreans drink more coffee than Delhites. So, the producers are selling coffee to consumers in Bangalore. The quantity bought will depend upon the consumer's income and desire for coffee.
Interaction of firms, households and government in the market1:
When the three principal actors in the market – firms (producers), households (consumers) and the government interact, we can observe a circular flow of income as pictured [http://www.bized.co.uk/virtual/dc/copper/theory/th11.htm here].
Households (consumers) buy goods and services from firms (producers), in turn for selling factors of production; firms sell goods and services to households in turn for buying factors of production. Consumers offer factors of production such as land and labour, and receive rent and wages as payment. They use their income to buy goods and services produced by firms. Both, firms and households pay taxes to the government, and in turn receive basic goods such as roads, schools, hospitals and safety services. Thus, the above figure neatly summarizes the roles of the three fundamental players in an economy.
