Final answer:
Germany's doubling of productivity does not change its specialization if it does not alter its comparative advantage. Germany should continue specializing in video cameras, while Poland should specialize in televisions, according to current comparative advantages.
Step-by-step explanation:
If Germany's productivity doubles for everything it produces, it will not necessarily alter its prior pattern of specialization if it has not altered its comparative advantage. Even if Germany acquires an absolute advantage in the production of both goods, it is the comparative advantage that determines specialization. Based on the example given, Germany should specialize in the production of video cameras because the opportunity cost of producing video cameras is lower in Germany than in Poland. Conversely, despite Germany's increase in productivity, Poland retains a comparative advantage in the production of televisions and should continue to specialize in them.
It is crucial to recognize that comparative advantage can evolve over time, suggesting that countries should be flexible and adapt to ongoing changes in comparative advantages. This means that while Germany's productivity increase doesn't currently alter its comparative advantage, it could potentially do so in the future as the economic landscape changes and new skills are developed.
