The new reality and big debate with the Covid pandemic have been "To wear a mask or not to wear a mask?" "To get the COVID-19 vaccine or not to get the COVID-19 vaccine?".

1) From an economics viewpoint, does wearing masks and/or getting the vaccine promotes positive externality or negative externality in the current COVID-19 environment? Explain.

2) Many governments worldwide (including the Canadian Federal Govt and the Ontario Provincial Govt) have implemented a "Vaccine Passport" policy for many sectors and specific industries in the economy. From an economic perspective, what is your opinion on this policy? Explain and substantiate your answer. Ensure you apply/incorporate economic topics learned in this course.

3) Reflection: We have discussed and learned many microeconomic topics in this course. Which one has made (or will make) a material impact in your future endeavours as a consumer, employee, or employer/entrepreneur? Why?
