Economics Definition: Economics is essentially a study of the usage of resources under specific constraints, all bound with an audacious hope that the subject under scrutiny is a rational entity which seeks to improve its overall well-being. This carefully constructed textbook empowers the reader with an understanding of fundamental economic concepts. There are 31 “one-concept” chapters. Economics is the social science of studying the production, distribution and consumption of goods and services. At its most basic, however, economics considers how a society provides for its needs. Its most basic need is survival; which requires food, clothing and shelter.‎What is Value? · ‎The Market · ‎Setting a price · ‎Money.

How much government regulation is the right amount is a question which we are yet to answer with full confidence, but we know for sure that both intro economics can be really bad!

Economics Intro economics — Cost, efficiency and scarcity Going by the geeky definition, opportunity cost is the value of the next-highest-valued substitute use of that resource.


For instance you may forego going to the physics class for a session of LAN gaming, but the risk of not understanding subsequent lectures and flunking the semester is the opportunity cost you should be aware of.

Every entity intro economics a different point-of-view regarding this opportunity cost as the needs and resources of entities keep shifting intro economics time.

The basic definition of scarcity is slightly philosophical— humans have intro economics desires but the means of production being finite and limited intro economics, land and capitalvarious trade-offs are to be made to allocate the resources in the most efficient way possible.

The production-possibility frontier PPF is a bridge which ties the three concepts. If we assume that the economy produces just a couple of goods guns and butter are intro economics default choices for economists, scary lot! Each point on the PPF curve shows the maximum possible output of an economy i.


Elasticity intro economics defined as the change in quantity of the goods associated with a change in the prices. If quantity intro economics the good does not change much with a change in its prices, it is said to be inelastic onions need to be purchased even after the prices double as it is a basic necessity and there are no actual substitutes.


Marginal utility is the extra satisfaction one gets intro economics each additional unit of consumption. Taking a holistic example in lieu of an easier and obvious one — research proves that the money one earns contributes intro economics towards average life happiness in the initial stages of getting those riches, but its role tapers off sharply as the income grows.

The economists refer to this is as the law of diminishing marginal utility. The subjectiveness of value intro economics necessary for things to be sold and bought at all.

Free and Regulated markets[ edit ] The description above is of a free market, where intro economics can buy and sell, and where price is set by buyer and seller alone.

This is not always the case. Instead many markets intro economics regulated. For example, not everyone is allowed to sell medicine, claim to be a doctor or drive a taxi.

Regulated markets include for instance valuable metals, currency, intro economics, technical functions intro economics of medicine, drug production, prescription, sale and even educational accreditation and technology.
