Business cycles

A business cycle is an uneven pattern of expansion and contraction. It is not a clock with identical intervals.

Expansion and Peak

Objective: Explain expansion and peak, distinguish their meanings, and apply them to a described case.

Expansion: An expansion is a period of broadly increasing economic activity. Peak: A peak marks the transition from expansion toward contraction in a dated cycle. Growth and business cycles address different timescales. A short recovery need not restore every household's position, and rising total output need not imply equal gains. Shocks can affect demand or production capacity and may interact. Cycle boundaries are analytical assessments rather than a fixed calendar. Historical observations and model assumptions should be distinguished when assessing causes and possible responses. Application: Output and employment generally rise across several indicators. This most directly illustrates expansion. Activity reaches a turning point before declining. This most directly illustrates peak.

Step 1 — Read the observation: Output and employment generally rise across several indicators. Step 2 — Recall the relevant idea: An expansion is a period of broadly increasing economic activity. Step 3 — Connect the observation to the idea: The scenario is an illustration of expansion. Step 4 — Check the limit: This short scenario illustrates the concept; it does not establish every detail or exclude every other influence in a real situation.

Contraction and Trough

Objective: Explain contraction and trough, distinguish their meanings, and apply them to a described case.

Contraction: A contraction is a broad decline in economic activity over a period. Trough: A trough marks the transition from contraction toward recovery. Growth and business cycles address different timescales. A short recovery need not restore every household's position, and rising total output need not imply equal gains. Shocks can affect demand or production capacity and may interact. Cycle boundaries are analytical assessments rather than a fixed calendar. Historical observations and model assumptions should be distinguished when assessing causes and possible responses. Application: Production and employment fall across several sectors. This most directly illustrates contraction. Activity stops declining before sustained improvement. This most directly illustrates trough.

Aggregate demand and Economic shock

Objective: Explain aggregate demand and economic shock, distinguish their meanings, and apply them to a described case.

Aggregate demand: Aggregate demand represents planned economy-wide spending in a macroeconomic model. Economic shock: A shock is an unexpected disturbance affecting economic conditions. Growth and business cycles address different timescales. A short recovery need not restore every household's position, and rising total output need not imply equal gains. Shocks can affect demand or production capacity and may interact. Cycle boundaries are analytical assessments rather than a fixed calendar. Historical observations and model assumptions should be distinguished when assessing causes and possible responses. Application: Households, firms, and governments change total planned expenditure. This most directly illustrates aggregate demand. A sudden supply disruption changes production possibilities. This most directly illustrates economic shock.
