Explanation of Solution

The required reserves are evaluated as follows:

Required Reserves=Required Reserve Ratio×Checkable deposits                             =0.25×200 billion                             =$50 billion

Hence, the required reserves are $50 billion.

The excess reserves are evaluated as follows:

Excess Reserves=Actual Reserves-Required Reserves                          =$52 billion-$50 billion                          =$2 billion

Hence, the excess reserves are $2 billion.

The maximum amount of a banking system is obtained by taking the product of the monetary multiplier and the amount of excess reserves. Thus, the monetary multiplier can be calculated as follows:

Monetary multiplier=1Required Reserve Ratio                             =10.25                            =4

Hence, the monetary multiplier is 4.

Then, the maximum amount of loans is evaluated as follows:

Maximum amount of loans=4×$2 billion                                         =$8 billion

Hence, the maximum amount of loan is $8 billion.

Table -1 shows the consolidated balance sheet obtained from the given diagram.

Reserves $52 $52 Checkable deposits $200 $208
Securities 48 48

Explanation of Solution

The required reserves are evaluated as follows:

Required Reserves=Required Reserve Ratio×Checkable deposits                             =0.20×$200 billion                             =$40 billion

Hence, the required reserves are $40 billion.

The excess reserves are evaluated as follows:

Excess Reserves=Actual Reserves-Required Reserves                          =$52 billion-$40 billion                          =$12 billion

Hence, the excess reserves are $12 billion.

Thus, the monetary multiplier is evaluated as follows:

Money multiplier=1Required Reserve ratio                          =10.2                          =5

Hence, the money multiplier is 5.

Then the maximum amount of loans is evaluated as follows:

Maximum amount of loans=Money multiplier×Excess Reserves                                         =5×$12 billion                                         =$60 billion

Hence, the maximum amount of loans is $60 billion.

Table -2 shows the new consolidated balance sheet obtained from the given diagram.

Table -2

Assets Liabilities and Net worth
(1) (2)
Reserves $52 $52 Checkable deposits $200 $260
Securities 48 48
Loans 100 160

With the required reserve ratio of 20% (rather than 25%), the difference in the amount of the commercial banking system is evaluated as follows:

Difference in the amount that the banking system can lend                                                        =(1st Maximum amount of loan-2nd Maximum amount of loan)                                                         =$60 billion-$8 billion                                                         =$52 billion

Hence, the banking system can lend $52 billion more.

. 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? They said that investment has declined, and government spending has declined too. They also said that GDP is expected to shrink in the next 6 to 10 months. I wonder what is next." Then, she looked at you and said: How…
