In the following scenarios, you will be given a product and an event. Determine what will happen to the demand for the product based on the event, what happens to the demand curve, and give the non-price determinant that caused it to occur. (chose from the 7 determinants listed in the notes). The first one is answered for you as an example.
EXAMPLE/ Product - Hamburgers Event - The price of steak increases Answer/ Demand increases - Curve shifts right - Price of substitutes
1. Pepsi - The price of Coke decreases dramatically.
2. Steak - Incomes fall due to the recession
3. Hair dye - Hair dye is successfully advertised in the media.
4. Computer software - The price of computers goes down.
The following graph shows the supply curve for sedans in an imaginary market. For simplicity, assume that all sedans are identical and sell for the same price. Two factors that affect the supply of sedans are the level of technical knowledge—in this case, the speed with which manufacturing robots can fasten bolts, or robot speed—and the wage rate that auto manufacturers must pay their employees. Initially, the graph shows the supply curve when robots can fasten 2,500 bolts per hour and autoworkers earn $25 per hour.
Suppose that the price of a sedan increases from $21,000 to $26,000. This would cause the quantity supplied of sedans to ________ (options: increase, decrease) , which is reflected on the graph by a ________ (options: shift of, movement along) the supply curve.
Suppose the workers' union negotiates a pay raise. This causes a _________ (options: leftward movement along, rightward movement along, leftward shift of, rightward shift of) the supply curve because the pay raise…

- Suppose that the quantity of corn supplied depends on the price of corn (P) and the amount of rainfall (R). The demand for corn depends on the price of corn and the level of disposable income (I). The equations describing the supply and demand relationships are Qs = 20R + 100P and Qd = 4000 − 100P + 10I. a) Sketch a graph of demand and supply curves b) Sketch a graph that shows the effect of an increase in rainfall on the equilibrium price and quantity of corn. c) Sketch a graph of demand and supply curves that shows the effect of a decrease in disposable income on the equilibrium price and quantity of corn.arrow_forwardThink of a relevant example in your own life of how a change in the market (including information, preferences, technology, price of alternative goods, regulations, taxes, etc.) has shifted either the supply or demand of a good. How did this change affect the market equilibrium for that good or service? Explain. Next, find a relatively recent news article (within the past year) to support your finding (the news search feature in Google is helpful with this). If you cannot find an article specific to your example, you may find an article about another similar good or service. Summarize the article and its findings, then include the URL in your discussion post. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.arrow_forwardSuppose one of your friends offered the following argument: a rightward shift in demand will cause an increase in price. The increase in price will cause a rightward shift of the supply curve, which will lead to an offsetting decrease in price. Therefore, it is impossible to tell what effect an increase in demand will have on price. Do you agree with your friend? If not, what is the flaw in your friend’s reasoning?arrow_forward

The law of demand states that as price of a good or service increases, the quantity demand decreases and vice versa. While the law of supply states that as prices of goods and services increase, the quantity supplied increases. The law of demand is a good concept for businesses when setting prices. As businesses raise prices, consumers may buy less of the product because their incomes are mostly stagnant. For example, a parent may buy 4 loaves of bread at $2 each which is $8, but may decide to only buy 2 loaves of bread when the price of a loaf of bread increases to $4. This is because the parent’s income is stagnant and he or she has allocated only $8 for bread.
