The market for Sony's Playstation5 game console has changed from 2021 to 2023. With restrictions from the Covid-19 pandemic ending people are finding other entertainment options available such as concerts, movies, and travel. Additionally, the microchip shortage is beginning to lessen, the custom-made AMD Zen 2 chip used in the PS5 has been decreasing in cost. Identify the appropriate market conditions and draw a clear graph to illustrate the market for Sony's Playstation5 game consoles in 2023 as compared to 2021.
1. Explain which non-price determinant(s) of demand and/or supply are changing.
2. Draw a graph on a piece of paper - label all axes, lines, and equilibriums. Include all relevant information.
3. Explain what is happening in the market with regard to equilibrium price and equilibrium quantity.
Draw a demand and supply graph for each of the following questions. For each question, start by drawing a correctly labeled graph of the market for cookies in equilibrium. Your starting graphs should each have correctly labeled axes and demand and supply curves. Label the equilibrium price and quantity as p1 and p2 on the axes of each of the starting graphs.
Show the effect on the equilibrium price and quantity in the market for cookies if the price of flour decreases. Determine which curve is affected by the change in the price of flour and whether it increases or decreases. On your graph, draw a new curve indicating the shift—either to the right or the left. Label the new equilibrium price and quantity as p2 and q2.

On the following graph, plot the demand for shoes using the blue point (circle symbol). Next, plot the supply of shoes using the orange point (square symbol). Finally, use the black point (plus symbol) to indicate the equilibrium price and quantity in the market for shoes.
Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.

Suppose that a new educational study has proven that the practice of writing, erasing, and rewriting improves students' ability to process information, leading parents to steer away from pen use in favor of pencils. Moreover, the price of ink, an important input in pen production, has increased considerably. On the following graph, labeled Scenario 1, indicate the effect these two events have on the demand for and supply of pens.

(graph in photo 2) Compare both the Scenario 1 and Scenario 2 graphs. Notice that after completing both graphs, you can now see a difference between them that wasn't apparent before the shifts because each graph indicates different magnitudes for the supply and demand shifts in the market for pens.

The demand curve has shifted significantly rightward. However, the price of a bunch of kale in the grocery store has been fairly stable. Draw a supply and demand diagram showing the market for kale, and show how the price of kale could remain stable in the face of such an enormous growth in demand. 1.) please plot the new supply and demand curves on a diagram and label the lines properly. 2.) please also indicate the new equilibrium point at the same price as the original equilibrium and label it.arrow_forwardPlease Help Me: Draw a demand and supply graph for each of the following questions.

- Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph. Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly. The equilibrium price in this market is__________________ per teapot, and the equilibrium quantity is__________________ teapots bought and sold per month. Complete the following table by indicating at each price whether there is a shortage or surplus in the market, the amount of that shortage or surplus, and whether this places upward or downward pressure on prices. Price Shortage or Surplus Shortage or Surplus Amount Pressure (Dollars per teapot) (Teapots) 48 Shortage 32arrow_forwardAssume that the equilibrium price is at $3 and equilibrium quantity is at 40 units of a product. Then, imagine that suddenly any of determinants of demand, other than the price of the product, caused demand to increase while, at the same time, one of determinants of supply, other than the price of the product, caused supply to decrease. TASK: First, draw the demand and supply graph to show the original equilibrium price at $3 and equilibrium quantity at 40 units. Second pick ONE specific DETERMINANT of DEMAND and ONE specific DETERMINANT of SUPPLY Third, show in the graph what it looked like if demand increased and supply decreased (select where you think that the new price and quantity would change to), what the new equilibrium price and equilibrium quantity would be, after both changes in demand and supply occurred. Fourth, in a couple of words, write down what would be YOUR new equilibrium price and equilibrium quantity.
