The Parliament of India

The Parliament of India comprises the head of state—the President of India—and the two Houses, which constitute the legislature. The President of India is elected for a five-year term by an electoral college consisting of members of federal and state legislatures.

Principles of Economics

Scarcity and Economics

Scarcity refers to the limited nature of society's resources. Economics is the study of how society manages its scarce resources.

How People Make Decisions

1. People Face Tradeoffs

Every decision involves tradeoffs. A significant tradeoff society faces is between:

• Efficiency: When society gets the most from its scarce resources.
• Equality: When prosperity is distributed uniformly among society's members.

Tradeoff Example: To achieve greater equality, income could be redistributed from the wealthy to the poor. However, this can reduce the incentive to work and produce, shrinking the overall economy.

2. The Cost of Something Is What You Give Up to Get It

Decision-making requires comparing the costs and benefits... Continue reading "Principles of Economics: A Comprehensive Guide" »

Qualitative Variables

Nominal Variables

Nominal variables are qualitative variables that cannot be ordered in an ascending or descending manner; that is, they cannot be ranked. For example, blood group.

Ordinal Variables

Ordinal variables are variables that can be ordered in an ascending or descending manner; that is, they can be ranked.

Quantitative Variables

Discrete Variables

Discrete variables are variables whose values are obtained by counting.

Continuous Variables

Continuous variables are variables whose values are obtained by measurement using a scale.

Mean

Advantages

• Has many good theoretical properties
• Used as the basis of many statistical tests
• Good summary statistic for symmetrical distribution
• Easy to calculate
• Possible for further algebraic treatment

Disadvantages

• Less

Metaphysics: An Introduction

The term *metaphysics* was coined by students of Aristotle. The literal meaning was "after the physics." Metaphysics is the branch of philosophy that addresses basic questions about the nature of reality.

Determinism and Freedom

According to determinism, everything that happens is determined by prior causes. The state of the universe at any moment could not be otherwise. One implication of this view is that all future states of the universe are, in principle at least, completely predictable. The principle that every event is caused is known as the *causal principle*. It is presupposed in science in everyday life. Most of the astonishing progress that science has made over the past four centuries has been made on the...

Negotiation Strategies: A Comprehensive Overview

Understanding Your Interests

• Your Interests: List them. What would be a great deal for you? Why do you want these things? What is the relative value of the different issues for you?
• Options: What are the range of options you have on each interest?

Alternatives and Communication

• Your Alternatives: What happens for you if there is no deal? What is your BATNA (Best Alternative To a Negotiated Agreement)? What is the worst possible deal you would still accept?
• Your Communication: What will you ask/what will you convey? What information do you need to get? What questions should you ask to test them? What facts can you use to convince? How to best frame them? What tough questions are they likely to ask?
