Explaining the Paradox of the Trader's Dilemma
Two traders, Dimitrios and Ameera, are being investigated for market manipulation. They are held separately and must decide simultaneously whether to 'Accuse' their colleague or 'Deny' the crime. The table below shows the prison sentence in years for each choice, with Dimitrios's outcome listed first and Ameera's second.
| Ameera: Deny | Ameera: Accuse | |
|---|---|---|
| Dimitrios: Deny | (1, 1) | (10, 0) |
| Dimitrios: Accuse | (0, 10) | (5, 5) |
Explain why, despite the fact that both traders would be better off if they both chose to 'Deny' (1 year each), the most likely outcome is that they both 'Accuse' (5 years each). In your explanation, analyze the decision-making process from the perspective of one of the traders.

Payoff Matrix for the Dimitrios and Ameera Game
Two traders, Dimitrios and Ameera, are being investigated for market manipulation. They are held in separate rooms and cannot communicate. Each must decide whether to 'Accuse' the other or 'Deny' the crime. The potential prison sentences (in years) are shown in the table below, with Dimitrios's sentence listed first and Ameera's second.
Ameera: Deny Ameera: Accuse Dimitrios: Deny (1, 1) (10, 0) Dimitrios: Accuse (0, 10) (5, 5) Based on a rational self-interest, what is Ameera's single best course of action, and why?
Predicting the Outcome of the Trader's Dilemma
Evaluating Outcomes in the Trader's Dilemma
Two foreign exchange traders, Dimitrios and Ameera, are under investigation for market manipulation. They are held separately and must decide simultaneously whether to 'Accuse' their colleague or 'Deny' the crime. The table below shows the prison sentence in years for each choice, with Dimitrios's outcome listed first and Ameera's second.
Ameera: Deny Ameera: Accuse Dimitrios: Deny (1, 1) (10, 0) Dimitrios: Accuse (0, 10) (5, 5) Statement: The most stable and likely outcome of this situation is that both traders will choose to deny the crime, as this leads to the best collective result (a total of 2 years in prison).
Two foreign exchange traders, Dimitrios and Ameera, are under investigation for market manipulation. They are held separately and must decide simultaneously whether to 'Accuse' their colleague or 'Deny' the crime. The table below shows the prison sentence in years for each choice, with Dimitrios's outcome listed first and Ameera's second.
Ameera: Deny Ameera: Accuse Dimitrios: Deny (1, 1) (10, 0) Dimitrios: Accuse (0, 10) (5, 5) Match each game theory concept to its corresponding description or outcome within this specific scenario.
Evaluating a Policy Change in the Trader's Dilemma
Analyzing the Incentive to Defect
Consider a scenario where two traders, Dimitrios and Ameera, are under investigation. They are held separately and must decide simultaneously whether to 'Accuse' their colleague or 'Deny' the crime. The authorities have structured the plea bargain such that the prison sentences (in years) are as follows, with Dimitrios's outcome listed first and Ameera's second:
Ameera: Deny Ameera: Accuse Dimitrios: Deny (2, 2) (10, 0) Dimitrios: Accuse (0, 10) (1, 1) Assuming both traders are rational and act solely in their own self-interest, what is the predicted outcome of this situation?
