The supply of money in the economy.

Answer to Problem 1QCMC
Option 'c' is the correct answer.
Explanation of Solution
Any commodity or item that a community accepts as payment for the goods and services is known as money. It can be any commodity that the consumer gives in exchange for goods and services. The banks are financial institutions that play an important role in a financial market.
Option (c):
The use of the lines of credit which are accessible with credit card cannot be considered as money supply because it is a debt instrument and there is no supply of money. Therefore, the lines of credit accessed through credit card are not included in the money supply. Thus, option 'c' is correct.
Option (a):
The metal coins are a form of money that is used by an economy for the purpose of the exchange of goods and services. They are accepted as payment for the goods and services. Hence, they are included in the money supply. Thus, option 'a' is incorrect.
Option (b):
Paper currency is a widely accepted form of money all over the world. Hence, it is included in the money supply of the economy. Thus, option 'b' is incorrect.
Option (d):
Bank balances that are accessible with debit cards are the savings of the customers and they are included in the money supply of the economy. When the bank balance increases, the money supply increases, and vice versa. Thus, option 'd' is incorrect.
Concept introduction:
Money: Money is any item that is accepted as payment for the goods and services provided by an economy.
Banks: Banks are financial institutions that accept deposits of money from the general public and use it to provide loans to the public.

- Richard has just opened a new restaurant. Not being good at deserts, he has contracted with Carla to provide pies. Carla’s costs are $10 per pie, and she sells the pies to Richard for $25 each. Richard resells them for $50, and he incurs no costs other than the $25 he pays Carla. Assume Carla’s costs go up to $30 per pie.

Suppose you are interested in studying the effect of the legalizing of fireworks on the number of house fires in North Dakota. Unlike North Dakota, South Dakota did not legalize fireworks and continued to ban them. You decide to use a Difference-in-difference (DID) Model. The numbers of house fires in each state at the end of 2000 and 2001 are as follows: Number of house fires in Number of house fires in Year North Dakota 2000 2001 35 50 South Dakota 54 64 a.

In the United States, if a baby has a birthweight below 1500 grams, the newborn is classified as having “very low birth weight". Suppose you want to study the effect of having very low birth weight on the number of hospital visits made before the baby's first birthday. You decide to use Regression Discontinuity to answer this question.

While laptop usage can help students take lecture notes faster, some argue that the laptops may be a source of distraction for the students. Suppose you are interested in looking at the effect of using laptops in class on the students' final exam scores out of 100. You decide to conduct a randomized control trial where you randomly assign some students at UIC to use a laptop in class and other to not use a laptop in class.
