Fair Division Concepts and Principles

The video introduces the concept of fair division, a method for dividing goods or assets among people so each receives a fair share. It covers the assumptions needed for fair division methods, such as non-cooperation and rationality, and explains that fair division doesn't need to be envy-free, Pareto optimal, or equitable. An example using pies illustrates how individual valuations affect fair shares. The video concludes with a classification of divisible items into continuously and discreetly divisible categories.

What is the primary goal of fair division?

• To ensure each party receives an equal share

• To minimize the number of items divided

• To maximize the total value of the division

• To ensure each party receives their fair share

Which of the following is NOT an assumption made in fair division methods?

• Parties act rationally

• Parties are non-cooperative

• Parties have knowledge of others' valuations

• No outside arbitrator is required

What does it mean for a division to be envy-free?

• No party prefers another's share over their own

• The division is completed quickly

• Each party receives an equal portion

• The division maximizes total value

What is a fair share when dividing something equally among N parties?

• Half of the total value

• N times the total value

• Twice the total value

• 1/Nth of the total value

Why does fair division not need to be Pareto optimal?

• Because it focuses on equal distribution

• Because it ensures no one is worse off

• Because it maximizes total value

• Because it only needs to ensure each party's fair share

In the example with Manny and the pies, what is Manny's valuation of the berry pie?

• $12

• $9

• $6

• $3

If Rita is allergic to berries, what is her fair share of the pies?

• One piece of apple pie

• One piece of berry pie

• Two pieces of apple pie

• Two pieces of berry pie

What is the value of each piece of apple pie for Manny?

• $1.00

• $0.75

• $2.00

• $1.50

What is the difference between continuously and discretely divisible items?

• Both can be divided into any size

• Discretely divisible items can be divided into any size, continuously divisible items cannot

• Continuously divisible items can be divided into any size, discretely divisible items cannot

• Neither can be divided into any size

Which of the following is an example of a continuously divisible item?

• A piece of land

• A piece of furniture

• A car

• A house
