➤ How do I calculate the MRS when dealing with different bill denominations?
Calculate the marginal utility from an additional $5 and from an additional $1, then take the ratio MU_5/MU_1. If utility is linear in dollars, marginal utility per dollar is constant and MRS equals five. You can also estimate MRS from the slope of an indifference curve at the current bundle.

➤ Why does a 10% reserve ratio limit a bank’s lending capacity?
A 10% reserve ratio requires banks to hold one‑tenth of deposits as required reserves. The remaining 90% can be lent as excess reserves in the first round. Each loan creates a deposit elsewhere, so lending recycles and declines by 10% each round. Cumulative lending equals initial reserves times the 1/R multiplier.

➤ Is capital income the same as capital gains?
No. Capital income usually refers to recurring returns like interest, dividends, rent, and profits. Capital gains are one-time or realized increases in asset prices when you sell an asset. Gains can become taxable income, but they differ conceptually because gains reflect changes in asset value, not ongoing payments for capital services.

➤ Why did some economies contract in 2001?
Several factors caused contractions in 2001. The global slowdown after the late 1990s investment boom, the dot‑com bubble collapse, reduced business investment, falling exports, and the 9/11 shocks in the United States all weakened demand. Tight credit conditions and banking stress also amplified declines in output and hiring in affected economies.

➤ How are assets classified on financial statements?
Accountants group assets by liquidity and purpose. Current assets include cash, short-term investments, receivables, and inventory. Noncurrent (long-term) assets include property, plant, equipment, long-term investments, and intangible assets like patents and goodwill. Classification affects reporting, ratios, depreciation and amortization on the balance sheet and informs liquidity and solvency analysis.
