NCERT Book Class 12 Economics (Macroeconomics) Chapter 1 Introduction

Chapter 1
You must have already been introduced to a study of basic
microeconomics. This chapter begins by giving you a
simplified account of how macroeconomics differs from the
microeconomics that you have known.
Those of you who will choose later to specialise in
economics, for your higher studies, will know about the
more complex analyses that are used by economists to
study macroeconomics today. But the basic questions of
the study of macroeconomics would remain the same and
you will find that these are actually the broad economic
questions that concern all citizens – Will the prices as a
whole rise or come down? Is the employment condition of
the country as a whole, or of some sectors of the economy,
getting better or is it worsening? What would be reasonable
indicators to show that the economy is better or worse?
What steps, if any, can the State take, or the people ask
for, in order to improve the state of the economy? These
are the kind of questions that make us think about the
health of the country’s economy as a whole. These
questions are dealt within macroeconomics at different
levels of complexity.
In this book you will be introduced to some of the basic
principles of macroeconomic analysis. The principles will
be stated, as far as possible, in simple language.
Sometimes elementary algebra will be used in the
treatment for introducing the reader to some rigour.
If we observe the economy of a country as a whole it will
appear that the output levels of all the goods and services
in the economy have a tendency to move together. For
example, if output of food grain is experiencing a growth, it
is generally accompanied by a rise in the output level of
industrial goods. Within the category of industrial goods
also output of different kinds of goods tend to rise or fall
simultaneously. Similarly, prices of different goods and
services generally have a tendency to rise or fall
simultaneously. We can also observe that the employment
level in different production units also goes up or down
together.
If aggregate output level, price level, or employment
level, in the different production units of an economy,
