Expert Solution

Explanation of Solution

Tabular presentation of player 1 and 2 game.

Player 2
Player 1		D	E	F
	A	-200,150	350,100	-50,600
	B	200,-300	400,400	300,100
	C	-150,200	-250,550	750,-350

Dominant strategy is the selection of move in the game which pays the maximum payoff given other player strategy.

According to the table,

Selection by Player 2	Reaction of player 1
D	B
E	B
F	C

It is noted that, when player 2 selects D, for getting the maximum payoff, player 1 selects B. Similarly, If E is selected by 2ⁿ^d player, 1 will choose B and so on. Thus, no dominant strategy exists for player 2 as player 2 choices rely on player 1 moves.

Thus, dominant strategy does not occur as players do not have independent moves.

b)

Expert Solution

Explanation of Solution

According to the game, there are various moves available for player second.

When player 2 choses strategy D, Player 1 has two options, that is, strategy A and C. With selection of A strategy, worst outcome is $-200 and at strategy C, worst outcome is -150.

When player 2 choses strategy E, player 1 has a worst outcome of -50 when strategy E is selected.

When player 2 choses strategy F, Player 1 has two options, that is, strategy A and C. With selection of A strategy, worst outcome is -50 and at strategy C, worst outcome is -350.

To get the secure strategy, maximum payoff available which is $200, $400 or $300 when strategy B is selected. Hence, strategy B is considered as secure strategy for player 1.

Economics Concept Introduction

Introduction:

A strategy is secure when any deviation from player 2 does not affect the payoff of player 1 having no dominant strategy.

c)

To determine

To ascertain: The Nash equilibrium.

c)

Expert Solution

Explanation of Solution

Nash equilibrium occurs when both players are maximizing their payoffs given other player’s move.

Therefore, Nash equilibrium occurs when player A choses B strategy while player B choses strategy E which gives payoff equal to each player.

Therefore, the Nash equilibrium in the game is (B,E).

Economics Concept Introduction

Introduction:

Nash equilibrium is a stable state in which different participants interact each other, in which no participant gain unilaterally, if strategy of other remains unchanged.
