A behavior over time graph and causal loop diagram Instructions: Read Jay Forrester's description died through the National Model), and then answer the questions that follow. > The National Economy When consumer demand increases, as it did in the 1950s, after World War 11, production rises. With expanding production, the need for more workers means manufacturing wages rise. At the same time, increasing production leads manufacturers to want to make even more profits. They need to expand, building more factories, warehouses, and distribution facilities, and they need to invest in more labor and raw materials. They have an insatiable demand for capital. With optimism high, banks are willing to finance a growing stream of loans, which go into, among other things, wages for the workers who construct the new plant and build the new equipment. In gen- eral, wages for both construction and production workers boom. This newly affluent middle class of workers satisfies its desire for the \"good life\" by spending ever more on cars, appliances, clothing, and electronics. QUESTIONS 1. Write a brief synopsis of the story. 12 Angry Jurors" is a play about a murder case concerning a son who has supposedly murdered his father and the decision-making and arguing that goes on behind the case. This play is not centered around the case itself, but rather on the 12 citizens chosen to decide the fate of the son, to decide whether he is innocent or guilty through observation of evidence as well as endless discussions. If there is any reasonable doubt at all, then they must decide that the boy is not guilty. The jury meets on a hot day, and their debate reflects the weather. With the endless clash of opinions, the argument grows to a high temperature, and only rises throughout the play. A decision is difficult to reach, and the jury is unable to agree on anything. 2 Identify the story's key variables. (Hint: Try to list seven.) 3. Graph these variables' behavior over time. 4 Draw the causal loop diagram. (Hint: The diagram contains two loops of the same type.)
