a. Draw the PPF (Production Possibility Frontier) of a country under normal times, with the two goods: health on the xaxis and economy on the yaxis. Discuss if the PPF curve slopes upward/downward and the tradeoff between the health and economy that countries face. Production Possibility Frontier of Japan under normal time: Based on the above diagram we have seen that the PPF curve slopes downward. According to the Libraries (n.d.), if the PPF curve slopes downward is an implication of scarcity. When PPF is downward sloping you need to make a trade-off. Because resources are limited, in order to maintain its economic growth over the years, Japan chooses to trade off the health of its people. The scarcity resource is personal time. Although the Japanese government has regulated working hours for employees ( 40 hours! week), 22% of the population continues to work for more than 50 hours per week (Eli Civil 2020). Overwork will greatly affect the health of the Japanese people. Japanese researchers have also found a relationship between overwork and heart-related diseases. (Der-Shin Re 2012)
