Explanation of Solution

- The law of demand is a fundamental economic principle. It states that as the price of a good increases, its quantity demanded decreases and vice versa. In other words, there is an inverse relationship between the quantity demanded and product price. The law is based on the assumption of ceteris paribus, that is, when all other factors affecting the demand remain constant. The other factors like consumer income, consumer tastes and preferences, prices of compliments and substitutes etc are exogenous factors which are assumed to be constant.

The figure below shows a downward sloping demand curve from left to right based on the law of demand. When the price of the good is $30, the quantity demanded is 50 thousand units and when the price increases to $60, the quantity demanded falls to 20 thousand units and so on.

. What the heck is this GDP thingy? It is Thursday afternoon, just a few days before the holiday season starts in your region, and you decided to visit your uncle Chao who owns a local delivery company. While sitting in the living room watching the evening news with your uncle, you heard the news reporter stating the following with an optimistic tone: "According to recent studies, gross domestic product (GDP) is rising due to an increase in consumer spending. The increase in spending was due to an increase in consumer confidence because the job market has shown a positive increase in both employment and income." Immediately, your uncle Chao looked at you with some confusion on his face and asked: What the heck is GDP, and why does the news dude seem excited about its increase? Does this “good” change in this GDP thingy have any effect on my delivery business? How? Do I need to do something different to prepare for the rise in GDP? How?
3. I need people who don’t want me! As an operations manager at a factory that produces manual tools, you were tasked with preparing a new site for expansion. The plan is to start production in the new location within 6 months from the current date. The new location requires 100 workers to operate fully. The workers you need don’t require any form of education or special skills because the tasks at the factory are simple and straightforward. In other words, you typically hire lower-skilled workers. In recent years, your company has been having problems finding workers who meet those criteria because the demand for them is so high. While sitting in your office, your teammate, Alejandra, walked to your office and said, "Have you heard the recent news about the economy?
