If a country produces more of Good A, which is known to have a high marginal cost, what is the opportunity cost associated with this decision in terms of Good B production?

When a country decides to produce more of Good A, which has a high marginal cost, it means that it has to give up a significant amount of Good B. This is because resources like land, labor, and capital are limited, so using them to make more of Good A means they cannot be used to make Good B. The opportunity cost is the value of the Good B that could have been produced instead. For example, if producing an additional unit of Good A requires sacrificing the production of two units of Good B, then the opportunity cost is those two units of Good B that the country could have had. This concept helps us understand the trade-offs that come with resource allocation in an economy.
