Q & A

What is the primary focus of financial economics?

Financial economics is the study of how individuals allocate their scarce resources over time under conditions of uncertainty, focusing on decision-making related to consumption, saving, borrowing, and investment.

Why is the financial system important for an individual's lifetime utility?

The financial system enables individuals to enhance their lifetime utility by providing mechanisms to manage the gap between consumption and income, offering various financial instruments for investment, and facilitating better decision-making throughout one's life.

What are the three financial transactions Kaleab engaged in to secure his business's operating fund?

Kaleab engaged in borrowing KRW 5 billion, issuing KW 4 billion in bonds, and issuing KW 1 billion in stock to secure the required operating fund for his business.

How does Kaleab's balance sheet look after securing the funds for his business?

Kaleab's balance sheet shows KW 10 billion in cash on the right-hand side, with KW 5 billion as short-term borrowing, KW 4 billion from bond issuance, and KW 1 billion from equity issuance.

What does Kaleab do with the USD 5 million he earned from exporting cabbage kimchi to the United States?

Kaleab converts the USD 5 million into KW, as he needs the local currency for transactions in Korea, through the FX spot market.

What is the difference between FX spot and FX forward transactions?

FX spot transactions involve the immediate buying or selling of currency, settled within two business days (T+2), whereas FX forward transactions involve a deal to buy or sell currency at a specified future date at a rate agreed upon today.

Why might Kaleab be interested in using FX forward contracts?

Kaleab might use FX forward contracts to hedge against the risk of currency fluctuations, ensuring a fixed exchange rate for the USD 5 million he will receive in three months, thus managing the uncertainty of future exchange rates.

What is the concept of negative carry in the context of Kaleab's financial transactions?

Negative carry occurs when the cost of funding an investment, such as through short-term borrowing, is higher than the yield received from the investment, like the 3% yield from KTB, resulting in a net loss over time.

How can Kaleab change a negative carry to a positive carry?

Kaleab can change a negative carry to a positive carry by replacing his short-term borrowing with a repo transaction, which is a form of short-term borrowing based on collateral, often at a lower rate, thus reducing the cost of funding.

What is the difference between repo sell and repo buy transactions?

Repo sell transactions involve selling a security and receiving cash in exchange, effectively borrowing against the security as collateral. Repo buy transactions, on the other hand, involve buying a security and lending cash, with the security acting as collateral for the loan.
