Economics comes from the Greek word oikonomia which means household chores. Economics is considered a field of social science. Economics is relevant because it is part of everybody’s life. As a science, Economics is related to other sciences.
Microeconomics: Introduction and basic conceptsPie GS
1.1 Meaning and definition of microeconomics
1.2 Basic microeconomic issues: scarcity, efficiency and
alternative uses of resources
1.3 Differences between microeconomics and macroeconomics
1.4 Opportunity cost, normative economics and positive
economics
1.5 Importance of microeconomics in business decision making
1.6 Economic models: meaning and use of economic models
The activity of seeking wealth is as old as Human
Civilization. Human beings either as individuals or as groups
or as large kingdoms and empires have always been engaged
in acquiring and increasing the material wealth.
However, a discipline study of the wealth producing
activities was commenced about 230 years back when Adam
Smith, the father of Economics, published “The Nature and
Causes of Wealth of Nations”. Economics, as a discipline,
constitute the most important subject to analyze activities
related to wealth creation and distribution. The dimensions of
the subject of Economics are truly vast and encompasses all
aspects of our lives.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Concept of Scarcity
Scarcity exists because individuals want more than
can be produced. It implies that there are not
enough resources to satisfy human wants.
The condition in which our wants are greater than
the resources available to satisfy them.
Scarcity means making choices. Wants are
unlimited and resources are limited. Therefore,
scarcity exists, and people must make choices.
12. BACHELOR OF ARTS IN ECONOMICS SOC SCI 104 – BASIC ECONOMICS W/ TAR

Wants versus Needs
Wants are desires that can be satisfied by
consuming a good or service.
Needs are things, such as food, clothing, and
shelter, that are necessary for survival.
Necessities are few but our wants are endless.

This is a key concept in economics, and has been
described as expressing "the basic relationship
between scarcity and choice“.
It is the cost of any activity measured in terms of the
value of the best alternative that is not chosen (that
is foregone).
It is the sacrifice related to the second best choice
available to someone, or group, who has picked
among several mutually exclusive choices.

Pangasinan State University
Social Science Department – PSU Lingayen
Individuals do make their choices randomly. Rather,
they carefully looked at the benefits they would gain
and the opportunity costs they would incur from their
decisions. This practice of examining the costs and
the expected benefits of a choice as an aid to decision
making is called cost-benefit analysis. It is an
approach that weighs the benefits of an action against
its costs. Cost-benefit analysis is one of the most
useful tools for individuals, businesses, and
governments when they need to evaluate the relative
worth of economic choices.

Economic System is the way in which a society decides
what goods to produce, how to produce them, and for
whom goods will be produced. Whether rich or poor, every
nation must answer the same three fundamental economic
questions:
1. What to produce?
2. How to produce?
3. For whom to produce?
Three Economic Questions
27. BACHELOR OF ARTS IN ECONOMICS SOC SCI 104 – BASIC ECONOMICS W/ TAR

Social Science Department – PSU Lingayen
What to Produce?
To answer the first fundamental economic question, a society
must decide the mix of goods and services it will produce. Will
it produce mainly food, or will it also produce automobiles,
televisions, computers, furniture, and shoes? The goods and
services a society chooses to produce depend, in part, on the
natural resources it possesses.
Because of scarcity, no country can produce every good it
wants in the quantity it would like. More of one good (say,
television sets) leaves fewer resources to produce other
goods (such as cars). No matter what nation we are talking
about—the United States, China, Japan, India, Russia, Cuba,
or Brazil—each must decide what goods will be produced.
28. BACHELOR OF ARTS IN ECONOMICS SOC SCI 104 – BASIC ECONOMICS W/ TAR
Pangasinan State University
Social Science Department – PSU Lingayen
How to Produce?
The next question every society has to answer deals with
the ways in which people produce the goods. Will farmers
using modern tractors produce food, or will farmers using
primitive tools produce it? Will the food be produced on
private farms, where production decisions are made by
individual farmers, or will it be produced on collective farms,
where production decisions are made by people in the
government?
Answering this second question involves using scarce
resources in the most efficient way to satisfy society’s wants.
Again, decisions on methods of production are influenced, in
part, by the natural resources society possesses.
29. BACHELOR OF ARTS IN ECONOMICS SOC SCI 104 – BASIC ECONOMICS W/ TAR
Pangasinan State University
Social Science Department – PSU Lingayen
For Whom to Produce?
This answers how goods and services are distributed among
people in society. This actually involves two questions.
Exactly how much should people get and how should their
share be delivered to them? Should everyone get an equal
share of the goods and services? Or should a person’s
share be determined by how much he or she is willing to
pay? Once the question of how much has been decided,
societies must then decide exactly how they are going to get
these goods to people. To do this, societies develop
distribution systems, which include road and rail systems,
seaports, airports, trains, ships, airplanes, computer
networks—anything that helps move goods and services
from producers to consumers in an efficient manner.

Economic System
An economic system is a set of economic
institutions that dominates a given economy.
a particular set of institutional arrangements and a
coordinating mechanism—to respond to the
economizing problem. It is a society decides what
goods to produce, how to produce them, and for
whom goods will be produced.
The way a society uses its scarce resources to
satisfy its people’s unlimited wants.

1. To produce the goods for consumption of the
population
2. To utilize the resources in efficient method of
production
3. To employ the labor force in occupations where
productivity is at optimum
4. To apportion the wealth and income available to
everyone in an equitable manner
5. To encourage innovation and technology in order to
maximize efficiency, optimize satisfaction and minimize
waste

Social Science Department – PSU Lingayen
Traditional economy is an economic system
in which the society produces what best
ensures its survival.
Resources are allocated according to long-lived
practices from the past.
People make economic decisions based on
customs and beliefs that have been handed
down from generation to generation.
Traditional Economy
34. BACHELOR OF ARTS IN ECONOMICS SOC SCI 104 – BASIC ECONOMICS W/ TAR
Pangasinan State University
Social Science Department – PSU Lingayen
Market economy is characterized by the private
ownership of resources and the use of a system of
markets and prices to coordinate and direct
economic activity.
Private individuals own most, if not all, the resources
and control their use.
The prices of goods and services are determined in a
free price system .
Market economy or capitalism is sometimes called
laissez-faire; translated from the French, this phrase
means “to let do,” or to let people do as they choose
without government intervention.

an economy characterized by public ownership of
virtually all property resources and the rendering of
economic decisions through central economic
planning.
Government owns most of the businesses and
makes all economic decisions.
There is no free competition because the
government is the only seller.
Countries using mainly the command system include
Turkmenistan, Laos, Belarus, Libya, Myanmar, Iran,
North Korea and the former Soviet Union.
Command Economy
37. BACHELOR OF ARTS IN ECONOMICS SOC SCI 104 – BASIC ECONOMICS W/ TAR
Pangasinan State University
Social Science Department – PSU Lingayen
Flaws of Command Economy
1. Running an economy is so complicated that some
resources are used inefficiently.
2. Because nobody in particular owns resources, each
person has less incentive to employ them in their highest-
valued use, so some resources are wasted.
3. Central plans may reflect more the preferences of central
planners than those of society.
4. Because government is responsible for all production, the
variety of products tends to be more limited than in a
capitalist economy.
5. Each individual has less personal freedom in making
economic choices.
In practice, the pure command system also has flaws, most notably:

Mixed Economy is a blend of market system and
some form of government regulation and control.
Private ownership of resources exists side by side
with substantial public ownership of resources and
government participation in economic activities.
This involves a degree of private economic
freedom mixed with a degree of government
regulation of markets.
The major and strategic industries are owned and
managed by the state while the minor industries
belong to the private sector.

To study economic problems, economists employ a
process of theoretical investigation called the
scientific method. Scientific method consists of four
steps.
1. Step One: Identify the Question and Define
Relevant Variables
2. Step Two: Specify Assumptions
3. Step Three: Formulate a Hypothesis
4. Step Four: Test the Hypothesis

Households are individuals or groups of people
living together and considered the consuming-unit of
the economy. They sell economic resources and buy
goods and services
Firms are the institutions that organize the
production of goods and services and are
considered the producing-unit of the economy. They
buy economic resources and they sell goods and
services.

Market is a place or any arrangement that brings
buyers and sellers together and enables them to get
information and do business with each other. The
circular flow model has two classifications of market.
Resource Market is a market in which a resource
(land, labor and capital) is bought and sold.
Land market, capital market, labor market
Product Market is a market in which a good or
service is bought and sold.
Components of the Circular-Flow Model:
Resource Market and Product Market

Real Flows (input-output flows) depicts the
flows of the economic resources (inputs) that go
from households through resource markets to
firms and of the goods and services that go from
firms through goods markets to households.
Money Flows indicates the flows of payments
made in exchange for the services of factors of
production and of expenditures on goods and
services.

When households choose the quantities of services of land,
labor, capital, and entrepreneurship to offer in resource
markets, they respond to the incomes they receive—rent for
land, wages for labor, interest for capital, and profit for
entrepreneurship. When firms choose the quantities of
factor services to hire, they respond to the rent, wages,
interest, and profits they must pay to households. Similarly,
when firms choose the quantities of goods and services to
produce and offer for sale in goods markets, they respond to
the amounts that they receive from the expenditures that
households make. And when households choose the
quantities of goods and services to buy, they respond to the
amounts they must pay to firms

The production-possibility frontier (or PPF )
shows or measures the maximum quantity of goods
that can be efficiently produced by an economy,
given its technological knowledge and the quantity of
available inputs.
Production Possibility Frontier
53. BACHELOR OF ARTS IN ECONOMICS SOC SCI 104 – BASIC ECONOMICS W/ TAR
Pangasinan State University
Social Science Department – PSU Lingayen
Like all other economic models, the PPC is based on
assumptions that simplify the economic interactions. For the
PPC these assumptions are:
1. Resources are fixed. There is no way to increase the
availability of land, labor, capital, and entrepreneurship.
2. All resources are fully employed. There is no waste of
any of the factors of production. In other words, the
economy.
3. Only two things can be produced. This assumption
simplifies the situation and suits the graphic format, with
one variable on each axis.
4. Technology is fixed. There are no technological
breakthroughs to improve methods of production.
Production Possibility Frontier
54. BACHELOR OF ARTS IN ECONOMICS SOC SCI 104 – BASIC ECONOMICS W/ TAR
Pangasinan State University
Social Science Department – PSU Lingayen
The PPF model demonstrates the following economic principles:
The economy is said to be operating efficiently if it is
operating on the production possibilities frontier (e.g. Point
A or B) because it is producing a mix of output that is the
maximum possible from the resources available.
Points inside the curve (e.g. Point C) are therefore
inefficient while points outside the curve (e.g. Point D) are
currently unattainable.
If the economy is operating on the production possibilities
frontier, we can see the tradeoffs society faces. To produce
more of one good, it must produce less of the other. The
amount of one good given up when producing more of
another good is the opportunity cost of the additional
production.
PPF: An Analysis
55. BACHELOR OF ARTS IN ECONOMICS SOC SCI 104 – BASIC ECONOMICS W/ TAR
Pangasinan State University
Social Science Department – PSU Lingayen
The production possibilities frontier is bowed outward
because the opportunity cost of producing more of a
good increases as we near maximum production of that
good. This is because we use resources better suited
toward production of the other good in order to continue
to expand production of the first good.
A technological advance in production shifts the
production possibilities frontier outward. This is a
demonstration of economic growth.

One way to express the relationship between
variables is with a graph.
Graphs serve two purposes:
1. Graphs offer a way to visually express
ideas that might be less clear if described
with equations or words.
2. When analyzing economic data, graphs
provide a way of finding how variables are
related in the world.

Variable and Constant
Variable is q quantity that assumes different values in a
particular problem. It is a value that may change within
the scope of a given problem or set of operations.
Constant is a quantity whose value remains unchanged
throughout a particular problem.
Numerical Constant – has the same value in all
problems
Parametric Constant (Parameter) – has the same
value throughout the problem but may assume
different values in different problems

Dependent and Independent Variables
Function is a relationship between two or more variables
such that a unique value of one variable is determined by
the values taken by the other variables in the function.
These variables can be:
Independent Variable – the variable representing the value
being manipulated or changed.
Dependent Variable – observed result of the independent
variable being manipulated
If every value of x is associated with exactly one value of y,
then y is said to be a function of x.
In the function, 𝑦 = 𝑓 𝑥 , 𝑦 is the dependent variable and
𝑥 is the independent variable.
