<span>Game theory is the study of math and logic behind problems and cooperation. It has logical steps that can be used in making life choices. In game theory, a dominant strategy of Nash equilibrium exist. Nash equilibrium is reach when players choose their own dominant strategy in no unilateral profitable deviation from any other players. In addition, no players would take action as long as other players remain the same. Therefore, Nash equilibrium is self-enforcing strategy. </span>

<em>in-game theory, a dominant strategy </em><em>Nash equilibrium</em><em> exists. </em>

<h2>Further explanation </h2>

As a theory derived from mathematics, of course game theory is also closely related to non-social sciences such as computer science, electronics, to physics. While from the standpoint of social science, it can be said that game theory seeks to explain human interactions and behavior (social science) from the rational side. In economics, the game theory explains business behavior, for example in marketing competition between two or several large companies that dominate the market (cartel).

<h3>In the following we discuss some basic interaction strategies as an introduction to game theory: </h3>

Dominant strategy

In the dominant strategy, each player has 1 optimal choice that is not dependent on the choice of other players. In this case, A will always choose "bottom" because rewards 2 ("bottom" - "left") or 1 ("bottom" - "right") are never worse than 1 ("top" - "left") or 0 ("top" - "right"). Likewise, for B, choosing "left" will never be worse than choosing "right", regardless of choice A. Thus, "down" and "left" are the dominant strategies for each player A and B.

Nash Balance (Nash Equilibrium)

When a dominant strategy does not occur, a balance can still be achieved if each player can choose optimally based on the expectations of the actions taken by other players. In the above situation, if player A chooses "top", the optimal choice for B is "left". Conversely, if B chooses "left", optimal choice A is "top". Thus, the "top" - "left" (yellow cell) is also a position of balance, which is called the Nash balance (Nash equilibrium). Thus, Nash's balance is a pair of strategies when choice A is the optimal choice for the condition of choice B, and vice versa.

The prisoner's dilemma

Another problem in Nash's balance is that if an equilibrium position is reached, the two parties make a choice that is not the most optimal. This condition is known as the prisoner's dilemma. We imagine, there are 2 prisoners (suspects) who were investigated separately without being able to guess at each other's choice of action.

There are still many variations of strategies in game theory and their assumptions that were not explained here. The real game theory application is very close to daily life. <em>Have you ever faced situations such as prisoners' dilemmas or other strategic interactions? Could there be a way of taking a solution that hasn't been conceived by game theory formulators until now? </em>

Since nominal wages were constant as the price level changed, you explain that a decrease in the price level leads to an _______

Wittaler [7]

Answer:

increase in real wages, hiring less workers

Explanation:

In the case when the nominal wages are remain same but at the same time the level of the price should changed so if there is an decrease in the level of the price so that means there is an increased in the real wages as it is an inverse relationship between the real wages and the price level due to this the firm could hired less workers as the wages are increased

Which of the following statements best characterizes a basic difference between market economies and centrally-planned economies

Alika [10]

Answer:

d. None of the above are correct.

Explanation:

In a centrally planned environment, the government make decisions on production.

In a market economy, market forces make production decisions.

Society relies more upon prices to allocate resources when the economy is centrally planned than a market economy.

The self-interest of households is reflected more fully in the outcome of a market planned economy than in the outcome of a centrally planned economy

Government plays a larger role in the economic affairs of a centrally planned economy than in the economic affairs of a market planned economy.

Maria currently earns a REAL/NOMINAL wage of $12.00 per hour; in other words, the amount of her paycheck each week is $12.00 per

Temka [501]

Answer:

1) 12/3= 4 gallons of milk per hour is her real wage

Her nominal wage is $12 per hour, we then divide her nominal wage by the price of gallon of milk in order to find out how many gallons of milk can she afford from one hour of work. 12/3=4 so 4 gallons of milk is her real wage per hour.

2) Workers and firms negotiate compensation packages and agree on a Nominal wage with those expectations in mind, as nominal wage is the actual amount of money that they get. If the price level turns out to be lower than expected, a workers nominal wage is the same because he will be paid the same amount of money, but his real wage will be higher than expected, because real wage refers to the purchasing power of your money and when price levels are lower than expected the worker can buy more goods and services from the same nominal wage, which means that his real wage is higher than expected

3) Her Nominal wage increased from 12 to 12.36 which is

(12.36-12) =0.36

0.36/12= 3%

So her Nominal wages increased by 3%

If inflation was 3% the price of milk would have been (1.03*3)= 3.09 but because inflation was 2% the price of milk was (1.03*3) = 3.06 so in order to find out the increase in real wage we will subtract inflation from the increase in nominal wage

Increase in nominal wage 3%

Inflation 2%

Real wage increase =3-2

= 2% real wage increase.

An insurance company faces an ethical dilemma. A faulty computer program designed to evaluate insurance claims has been denying

kicyunya [14]

Answer: B) Whistleblowing

Explanation:

Whistleblowing is an act where someone in a company discloses unethical practices usually from the entity that they work in. It is a very risky thing to do because it could signal the end of one's career in a certain industry.

Whistleblowing however helps in contributing to entities staying ethical because they'd rather avoid the bad publicity that comes with it and this is why most companies have a whistleblowing policy to make it easier for people to come forward.

Whistleblowing can be done to the Government, the press or even the entity at fault itself.

Lori by giving an anonymous tip to the press about unethical behavior has engaged in Whistleblowing.

Examples of some well known Whistleblowers include, Edward Snowden and Chelsea Manning.
