Answer:
Reducing trade barriers
Explanation:
<u>If governments choose protectionism, they harm citizens who could benefit from the products, services or jobs offered by foreign companies.</u>
If, for example, the “A” government sets <em>tariffs to protect the domestic market</em>, the “B” government <em>could respond with tariffs in retaliation</em>, which would result in both countries being harmed. So, the problem of trade warfare is still represented by a “Prisoner's Dilemma” game because it says that two people, in this case, two governments, can decide not to cooperate even if it goes against the interest of both.
On the other hand, <em>unrestricted free trade could go against governments that develop trade policies based on national economic well-being.</em>
The game's equilibrium solution would be for both countries to opt to reduce their trade barriers through negotiations.
