Final answer:
To determine which country has a comparative advantage, calculate the opportunity cost of producing one more television in Germany and Poland. Germany would have a comparative advantage if it has a lower opportunity cost compared to Poland. For radios, a similar comparison between Japan and Malaysia would indicate the comparative advantage.
Step-by-step explanation:
To calculate the opportunity cost of producing one additional television set in Germany and in Poland, we need to know what each country must give up in terms of the next best alternative when they decide to produce that television. However, since the specific production data is missing in the question, we will consider a general case where these countries can produce either televisions or some other good, let's say radios.
If Germany can produce 10 televisions or 15 radios, the opportunity cost of one television in terms of radios is 1.5 radios (15/10). Similarly, for Poland, if it can produce 5 televisions or 20 radios, the opportunity cost of one television is 4 radios (20/5).
A country has a comparative advantage in the production of a good if it can produce it at a lower opportunity cost than another country. So between Germany and Poland, Germany has the comparative advantage in producing televisions because it has a lower opportunity cost (1.5 radios compared to Poland's 4 radios for one television).
In the case of calculating the opportunity cost of producing 80 additional radios in Japan and in Malaysia, a similar method would be used, comparing the opportunity costs between the two countries to determine which one has a comparative advantage in producing radios.
