Show the effect of this change on the market for peanut butter by shifting one or both of the curves on the following graph, holding all else constan
it will shift the demand curve up and the supply curve will not move
If a shortage exists in the car market, then the current price must be (higher/lower) than the equilibrium price. For the market to reach equilibrium, you would expect (buyers to offer higher prices/ sellers to offer lower prices)
lower and buyers to offer higher prices Prices below the equilibrium price generate excess demand because buyers are willing to purchase more cars than sellers are willing to sell—the quantity supplied is less than the quantity demanded at that price. Some buyers who wish to purchase cars at the current price will be unable to do so. In order to purchase cars, some buyers will offer higher prices. As buyers bid and drive prices upward, some sellers will be willing to sell additional cars. Therefore, the market will move toward the equilibrium price, where the quantity of cars demanded by buyers equals the quantity supplied by sellers.
When economists say an individual has made a rational choice, they mean the individual has
made the choice by weighing their own subjective costs and benefits.
An economy produces hot dogs and hamburgers. If a discovery of the remarkable health benefits of hot dogs were to change consumers' preferences, it would

possible to increase production of all goods simultaneously.
Refer to Table 2-3. The farmer and the rancher both could benefit if the farmer were to specialize in
potatoes and the rancher were to specialize in meat.

resources are specialized, that is, some are better at producing particular goods rather than other goods.

C- the government imposing excessive levels of taxation. D- firms using their monopoly power to enforce excessive price hikes.
A- If a nation has high and persistent inflation, the most likely explanation is the central bank creating excessive amounts of money The usual suspect in cases of large or persistent inflation is growth in the quantity of money. When a government's central bank creates large quantities of money, the value of that money falls, causing prices to rise and resulting in inflation.

John is selling his pizza for $6 per slice in an area of high demand. However, customers are not buying his pizza. Using what you learned about the principles of equilibrium, write three to four sentences about how John could solve his problem.
John's prices are too high. This is causing excess supply: John's workers can make many pizzas, but at these high prices, consumers are only demanding a small amount. If the price per slice decreased, consumers would demand more of John's pizza. This means that business would move toward a point of equilibrium, where supply matches demand at the appropriate price.

1 hour working in problems, 3 hours reading
The teaching assistant in Felix's economics course gives him some advice. "Based on past experience," the teaching assistant says, "working on 100 problems raises a student's exam score by about the same amount as reading the textbook for 1 hour." For simplicity, assume students always cover the same number of pages during each hour they spend reading. Given this information, in order to use his 4 hours of study time to get the best exam score possible, how many hours should he have spent working on problems, and how many should he have spent reading
