Use economics to explain the important elements to consider in the decision to open the economy under threat of Covid 19.

You should consider the relevance of the economic principles, standard assumptions , models, and problems you have learned so far (marginal thinking, opportunity costs, scarcity, rationality, free rider problem and others). Limit your answer to 200 words.

(You can get a good score with fewer words than that. You will be penalized for incorrect economic thinking, so more is not always better. If you answer in bullet points your statements should still be complete and understandable.)
