Table of Contents Introduction to Elasticity We've already studied how supply and demand curves act together to determine market equilibrium, and how shifts in these two curves are reflected in prices and quantities consumed.
Posted by admin May 3, Microeconomics 19 Determining the Shutdown Point of a Firm This continues a previous post on profit maximization. The question we want to continue with is when should a firm shutdown?
This is the output where firms are indifferent between producing the profit-maximizing quantity ie.
Take a look at this graph to help you understand the when and where. The supply curve for each firm is simply its marginal cost MC curve above the minimum point on the average variable cost AVC curve. Carrying on, what about the items that dictate and influence long run decision making? Forces in a competitive industry ensure that firms earn zero economic profits in the long-run.
Competitive industries will adjust in two ways: Entry and exit, 2. Changes in plant size Entry and Exit: The prospect of persistent profit of loss causes firms to enter or exit an industry. If firms are making economic profits, other firms enter the industry. This graph shows how where there is room for new entrants in the market and how it eliminates industry profits in the long run.
If firms are making economic losses, some of the existing firms exit the industry. This entry and exit of firms influences prices, quantities, and economic profits. This graph depicts economic losses in the industry. As firms leave an industry, the price rises and the economic loss of each remaining firm decreases.
When a firm changes its plant size, it can lower its costs and increase its economic profit. Therefore, in the long-run equilibrium for a competitive industry, all firms must be: Unable to increase profits by altering its scale of operations. And that concludes our intro into profit maximization and shut down points for firms.Class 12 Economics Notes.
Key Notes for Economics Subject for Class 12 Students are given here. Important topics of 12th Economics are covered. Economics is divided into two parts i.e.
Part A – Microeconomics and Part B – Macroeconomics. These notes will provide you overview of all the chapters and important points to remember. ECO— PRINCIPLES OF MICROECONOMICS—Notes Overview This chapter deals with demand and supply, two of the most fundamental concepts in economics.
We will analyse the factors that determine the behaviour of individuals with regard to demand for goods and services, the respective behaviour of business firms with regard to the supply of goods. Intro to Microeconomics Exam 1: Chapters 15 Monday, October 1, Objectives Chp 1- Define economics and distinguish between micro and macro economics- Explain the notion of opportunity cost- Identify the opportunity cost of a given action/choice- Use marginal analysis to predict decisions- Describe the benefit of allocating resources using economic markets and the limits of such markets.
The prefix micro means small, indicating that microeconomics is concerned with the study of the market system on a small scale.
Microeconomics looks at the individual markets that make up the market system and is concerned with the choices made by small economic units such as individual consumers, individual firms, or individual government agencies.

Microeconomics (from Greek prefix mikro-meaning "small" + economics) is a branch of economics that studies the behaviour of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms.
