Maximax | Minimax | Minimax Regret | Payoff Tables | Decision Making | Risk | Commerce Specialist |
TLDRIn this video, the Commerce Specialist explores decision-making under risk and uncertainty using three methods: Maximax, Maximin, and Minimax Regret. The Maximax method is favored by risk-seeking managers aiming for maximum profit, demonstrated through a payoff table comparing three projects. Maximin is used by risk-averse managers, focusing on the worst-case scenario to minimize losses. The Minimax Regret rule helps to identify the project with the least regret or loss if a wrong decision is made. The video is educational, targeting academic and professional qualifications.

Q & A
What are the three decision-making methods discussed in the video?
-The three decision-making methods discussed in the video are Maximax, Maximin, and Minimax Regret Rule.
What type of managers are likely to use the Maximax decision rule?
-Risk-seeking managers who prioritize maximum profit regardless of the risk involved are likely to use the Maximax decision rule.
How does the Maximax decision rule work?
-The Maximax decision rule involves identifying the maximum potential profit for each project under various scenarios and then selecting the project with the highest maximum profit.
What is the difference between Maximax and Maximin decision rules?
-Maximax focuses on the maximum potential profit in any scenario, while Maximin focuses on the minimum potential profit to ensure the least loss in the worst-case scenario.
Why would a manager choose the Maximin decision rule?
-A manager would choose the Maximin decision rule if they are risk-averse and want to minimize potential losses by focusing on the highest minimum return among the projects.
How is the Minimax Regret Rule different from the other two methods?
-The Minimax Regret Rule involves calculating the opportunity cost or 'regret' of choosing a project over the one that could have provided the highest profit in each scenario, and then selecting the project that would result in the least regret if a wrong decision is made.
What is the purpose of creating a regret table in the Minimax Regret Rule?
-The purpose of creating a regret table is to measure the difference between the maximum profit that could have been achieved and the actual profit of the chosen project for each scenario, which helps in identifying the project with the least potential regret.
How does the video script illustrate the application of these decision rules?
-The video script uses a table with three projects (Alpha, Bravo, Charlie) and three economic scenarios (very good, good, poor) to demonstrate how each decision rule would be applied to choose the best project.
What is the significance of the 'maximum regret' in the Minimax Regret Rule?
-The 'maximum regret' in the Minimax Regret Rule signifies the highest potential loss if the wrong decision is made. It helps in selecting the project that would minimize the loss in case of an incorrect decision.
What advice does the commerce specialist give at the end of the video?
-The commerce specialist advises viewers to subscribe to the channel for regular updates, join the focus group for ACC and CMA classes, and share the video with friends and family to benefit from the content.
Outlines
📈 Decision Making Under Risk and Uncertainty
This paragraph introduces the topic of decision making under conditions of risk and uncertainty, focusing on three specific methods: maximax, maximin, and minimax regret rule. The speaker presents a scenario involving three projects (Alpha, Bravo, and Charlie) and three economic conditions (very good, good, and poor), each with different profit or loss outcomes. The maximax decision rule is explained as a strategy for risk-seeking managers who aim for the highest possible profit regardless of risk. The maximin rule is introduced for risk-averse managers who prioritize the best possible outcome in the worst-case scenario. The paragraph concludes with a brief mention of the minimax regret rule, which will be explained in the next paragraph.
🔢 Maximax, Maximin, and Minimax Regret Decision Rules
The second paragraph delves deeper into the maximin and minimax regret decision rules. The maximin rule is described as a strategy for managers who are very risk-averse, focusing on the minimum potential loss in any scenario to ensure financial safety. An example is given where the minimum returns for each project under different economic conditions are compared, and the project with the highest minimum return (Charlie) is chosen. The minimax regret rule is introduced, which involves creating a regret table to calculate the opportunity cost of not choosing the project with the highest profit in each scenario. The table is used to determine the maximum regret for each project, and the project with the lowest maximum regret (Charlie) is selected as the best option to minimize potential loss even when a wrong decision is made. The paragraph ends with a call to action for viewers to join the speaker's focus group for further learning and to subscribe to the channel for more informative videos.

Highlights
Today's video discusses decision-making under risk and uncertainty.
Three methods for decision-making are introduced: maximax, maximin, and minimax regret rule.
Maximax is used by risk-seeking managers who aim for maximum profit regardless of risk.
Maximin is favored by risk-averse managers who focus on the minimum return to avoid loss.
Minimax regret rule is for managers who want to minimize potential regret from wrong decisions.
A payoff table is used to compare the profits of different projects under various economic scenarios.
Under maximax, the manager selects the project with the highest potential profit.
Under maximin, the choice is the project that guarantees the highest minimum return.
A regret table is prepared by comparing the opportunity cost of not choosing the best option.
In a regret table, the highest profit in each scenario is identified to calculate regret.
The minimax regret rule selects the project that offers the least regret even in the worst-case scenario.
The video provides a practical example using three projects and three economic scenarios.
Project Alpha, Bravo, and Charlie are evaluated under different decision criteria.
The maximax decision leads to the selection of Project Bravo for its highest potential profit.
The maximin decision results in choosing Project Charlie for its highest minimum return.
The minimax regret rule concludes with Project C as the safest choice to minimize regret.
The video is aimed at commerce students and professionals looking to enhance decision-making skills.
The channel offers focus classes for ACC and CMA qualifications and other benefits.
