what points on, below and above the PPF represent.

- Q. 4 The goal of this assignment is to think about the Productions Possibilities Frontier model and use it to describe a trade-off that you personally have experienced. You will have to identify two simultaneously produced economic outputs (goods, services, benefits, etc.) and the relationship between them. You will need to draw a graph and give information about the graph you made. Each point on the graph is a unique production point representing an amount of health care and military (H and M). We know that the set of production points possible is limited, given our limited resources in society. We can't have infinite amounts of H and M, so naturally, our representation of a productive economy must have a boundary where we have reached our productive capacity.arrow_forwardOn the following graph, use the blue line (circle symbol) to plot Nick's production possibilities frontier (PPF), and use the purple line (diamond symbol) to plot Rosa's PPF.
