Difficulty: Very hardEconomic Indicators and Business Cycle Phases

A macro research desk is mapping how financial and economic metrics respond as the overall economy reaches a peak and transitions into a contraction. Order the following four macroeconomic indicators based on their historical timing relative to the peak of the business cycle, starting with the earliest indicator to turn downward (most leading) and ending with the latest indicator to turn downward (most lagging).

  1. 1S&P 500 Index of common stock prices
  2. 2Personal income excluding government transfer payments
  3. 3Prime rate charged by commercial banks
  4. 4Ratio of consumer installment credit outstanding to personal income

Answer

The correct chronological sequence from earliest turning point to latest turning point is: S&P 500 Index of common stock prices, Personal income excluding government transfer payments, Prime rate charged by commercial banks, and Ratio of consumer installment credit outstanding to personal income.
The correct ordering places the leading indicator first, followed by the coincident indicator, and ending with the short-lag and long-lag indicators. Financial markets (S&P 500) discount future economic conditions and peak first. Real-time measures of output and income (Personal income excluding transfers) turn at the peak itself. Interest rate benchmarks (Prime rate) and consumer leverage metrics (Consumer installment credit to personal income) adjust only after the downturn is established, with debt-to-income ratios exhibiting the longest delay.

Step-by-Step Solution

1
Identify the leading indicator among the choices
The S&P 500 Index is a recognized leading indicator because asset markets anticipate future corporate earnings and economic shifts well before they materialize in real output.
Leading indicators turn prior to peak economic activity.
2
Identify the coincident indicator among the remaining items
Personal income less transfer payments directly measures current economic activity in real time and turns concurrently with the broader business cycle peak.
Coincident indicators reflect current economic conditions.
3
Differentiate between short-lag and long-lag indicators
The prime rate changes in response to short-term market interest rate movements and Fed policy adjustments following an economic turning point.
Prime rate is a primary lagging indicator.
4
Determine the indicator with the longest lag window
The ratio of consumer installment debt to personal income peaks long after a recession begins because consumers adjust borrowing habits slowly and existing balances linger relative to falling income.
Consumer credit ratios exhibit the longest lag among standard financial metrics.

Key Concept

Classification and relative chronological timing of leading, coincident, and lagging economic indicators across business cycle turning points.
