The Rules of a Game in Game Theory
Sequential vs. Simultaneous Games
The fundamental difference between sequential and simultaneous games lies in the timing of player actions and the information available to them. In simultaneous games, like the prisoners' dilemma, players act concurrently without knowledge of their opponents' choices. Conversely, in sequential games, such as the ultimatum game, players move in a specified order, allowing later players to observe and react to the moves of those who acted before them.

Sequential Game
Sequential vs. Simultaneous Games
Simultaneous Game
Two competing food trucks, 'Taco Town' and 'Burrito Boulevard', are the only vendors in a park. Each morning, they must independently decide whether to set a 'High Price' or a 'Low Price' for their lunch specials. Their daily profit depends on the combination of prices they both choose. Now, suppose the park management introduces a new rule: 'Taco Town' must publicly post its price for the day at 9 AM, while 'Burrito Boulevard' can wait to post its price until 10 AM, after seeing Taco Town's price. Which fundamental component of this strategic interaction has been altered by the new rule?
Analyzing a Business Competition
In the formal description of a strategic interaction, there are four key components that define the 'rules of the game'. Match each component with its correct description.
Deconstructing a Strategic Scenario
In a strategic interaction, the specific choices that players will ultimately make are considered one of the fundamental 'rules of the game' that must be defined beforehand.
Consider the following strategic situation: Two coffee shops, 'The Daily Grind' and 'Espresso Express,' are the only coffee shops in a small town. Each morning, they must simultaneously decide whether to offer a 'Discount' or maintain a 'Regular Price' on their main product. For this situation to be formally defined as a 'game,' which of the following essential components is missing from the description?
Altering Strategic Advantage
Two competing firms, Innovate Inc. and TechCorp, must simultaneously decide whether to invest in 'High-Cost R&D' or 'Low-Cost R&D'. The profits for each firm depend on the choices made by both. For example, if Innovate Inc. chooses 'High-Cost' and TechCorp chooses 'Low-Cost', Innovate Inc. earns a profit of 2 million. The complete set of potential profit outcomes for both firms, determined by every possible combination of their choices, constitutes the ________ of the game.
When formally describing a strategic interaction, it is necessary to establish a clear set of rules. Arrange the following components into the most logical sequence for defining such an interaction.
Consider the following situation: A single farmer must decide whether to plant wheat or corn. The farmer's profit depends solely on the weather conditions for the growing season, which are unpredictable. Based on the formal definition of a strategic interaction, why does this scenario NOT qualify as a 'game'?
