6	12
8	6
10	0

Budget line/  budget constraint

b). Answer:

When the Annie's income increases from $60 to $80 then budget line will shift right or outward.

c). Answer:

There are two features of indifference curve (IC):

1). Higher IC, refers higher satisfaction level for the consumers.

2). Any point on an IC, refers the equal level of satisfaction for the consumers.

According to the the indifference curve features,

A>C

C = B (because both are plotted on the same IC)

A = B (because both are plotted on the same IC and B is the intersection point)

So, if

C= B and A = B

then A = C

But According to the curve A>C

So, IC never intersect proof.

2)(a) The Nash Equilibrium is a decision-making theorem within game theory that states a player can achieve the desired outcome by not deviating from their initial strategy. ... Every player wins because everyone gets the outcome they desire.

(b) In marketing strategy, first-mover advantage(FMA) is the advantage gained by the initial ("first-moving") significant occupant of a market segment. First-mover advantage may be gained by technological leadership, or early purchase of resources.

A market participant has first-mover advantage if it is the first entrant and gains a competitive advantage through control of resources.With this advantage, first-movers can be rewarded with huge profit margins and a monopoly-like status.

(c) Examples of games with two nash equilibrium:

Example: coordination between players with different preferences

Two firms are merging into two divisions of a large firm, and have to choose the computer system to use. In the past the firms have used different systems, I and A; each prefers the system it has used in the past. They will both be better off if they use the same system then if they continue to use different systems.

We can model this situation by the following two-player strategic game.

	Player 2
	I	A
Player 1	I	2,1 0,0 0,0 1,2
A

To find the Nash equilibria, we examine each action profile in turn.

(I,I)

Neither player can increase her payoff by choosing an action different from her current one. Thus this action profile is a Nash equilibrium.

(I,A)

By choosing A rather than I, player 1 obtains a payoff of 1 rather than 0, given player 2's action. Thus this action profile is not a Nash equilibrium. [Also, player 2 can increase her payoff by choosing I rather than A.]

(A,I)

By choosing I rather than A, player 1 obtains a payoff of 2 rather than 0, given player 2's action. Thus this action profile is not a Nash equilibrium. [Also, player 2 can increase her payoff by choosing A rather than I.]

(A,A)

Neither player can increase her payoff by choosing an action different from her current one. Thus this action profile is a Nash equilibrium. We conclude that the game has two nash equilibrium.

(d) In game theory, the Nash equilibrium, named after the mathematician John Forbes Nash Jr., is a proposed solution of a outcome by not deviating from their initial strategy. ... Every player wins because everyone gets the outcome they desire.

(e) If each player has chosen a strategy—an action plan choosing its own action based on what it has seen happen so far in the game—and no player can increase its own expected payoff by changing its strategy while the other players keep theirs unchanged, then the current set of strategy choices constitutes a Nash .
