Loan Disbursement as Bank Deposits in the Marco-Julia Model

Consider a simple economy with two individuals. One individual, the 'Saver', begins with 100 units of a good but has no immediate way to make it more productive. The other individual, the 'Investor', has a project that can turn 30 units of the good into 60 units in the future, but currently has no units. A financial institution is established. The Saver deposits 50 units into the institution. The institution then lends 50 units to the Investor, who uses 20 for immediate needs and invests the remaining 30 in the project. Based on this scenario, what is the primary economic function performed by the financial institution?

Consider a simple economy where one individual has an initial endowment of 100 units of a good. They consume 50 units and deposit the remaining 50 units in a newly established bank. The bank then lends these 50 units to another individual who had no initial endowment. True or False: The bank's intermediation has increased the total quantity of the good available for use (i.e., for consumption and investment) in the economy during this initial period.

Calculating Economic Aggregates with a Financial Intermediary

Analyzing Financial Positions in a Simple Economy

In a simple two-person economy with a financial intermediary, a 'Saver' starts with 100 units of a good and a 'Borrower' starts with none. The Saver consumes half of their endowment and deposits the other half with the intermediary. The intermediary then lends the full deposited amount to the Borrower, who uses 30 units for a productive project and consumes the rest. Match each economic agent to their correct financial position after these initial transactions.

In a simple economy, a 'saver' starts with 100 units of a good, and a 'borrower' starts with none. A bank acts as an intermediary. Arrange the following transactions into the correct logical sequence to show how the saver's funds are channeled to the borrower for consumption and investment.

The Role of Financial Intermediation in a Simple Economy

In a simple economy, a 'Saver' starts with 100 units of a good. They consume 50 units and deposit the remaining 50 units in a bank. The bank lends these 50 units to a 'Borrower', who invests 30 units and consumes the rest. In this initial period, the total consumption for the entire economy is ____ units.

Consider a simple economy with two individuals and one good. A 'Saver' starts with an endowment of 100 units of the good, while an 'Investor' has a productive project but no units of the good. The Saver consumes 50 units and deposits the other 50 in a newly formed financial institution. This institution then lends the 50 units to the Investor, who uses 30 units for the productive project and 20 units for their own consumption. Which of the following statements most accurately evaluates the role of the financial institution in this initial period?
