Verified Answer :

  • The business cycle moves through phases of expansion, peak, contraction, and trough.
  • Economic output and unemployment have an inverse relationship; as output declines during contraction, unemployment rises.
  • The unemployment rate hits its minimum at the peak (point 3) and begins its upward trend immediately as the economy enters the contraction phase.
  • Therefore, the unemployment rate begins to increase at point 3.
  • The final answer is \(\boxed{3}\).

Explanation

  1. Understanding the Business Cycle

The business cycle is a central concept in economics representing the fluctuations in economic activity over time. It is typically visualized as a wave-like curve on a graph where the horizontal axis represents time and the vertical axis represents economic output (such as GDP). The cycle is divided into four distinct phases:

  1. Expansion: The economy is growing, with increasing output and declining unemployment.
  2. Peak: The economy reaches its highest point of output; unemployment is at its lowest point.
  3. Contraction (or Recession): The economy is shrinking, characterized by declining output and rising unemployment.
  4. Trough: The economy hits its lowest point before the next expansion phase begins.
  1. The Relationship Between Output and Unemployment

Economic theory, specifically Okun's Law, describes the inverse relationship between economic output and unemployment. When economic output is increasing (expansion), firms hire more workers to meet demand, lowering the unemployment rate. When the economy reaches its peak, output is at its maximum and the unemployment rate is at its minimum. As the economy begins to shift from the peak into a contraction phase, output starts to decline. Because businesses reduce production in response to falling demand, they begin to lay off workers, causing the unemployment rate to rise. Therefore, the transition point from peak to contraction is where the unemployment rate begins to turn from its lowest point and start increasing.

  1. Identifying the Turning Point

In a standard business cycle graph, points are generally mapped to the sequence of the cycle. Given the cycle's progression, point 1 typically represents the trough, point 2 represents the expansion phase, point 3 represents the peak, and point 4 represents the contraction phase. Since the peak (point 3) is the turning point where economic growth ends and contraction begins, it is the specific stage where the downward trend of unemployment stops and the upward trend begins. Thus, the unemployment rate begins to increase at point 3.

Examples

Consider a national economy that has been growing steadily for three years, with new businesses opening and record-low unemployment. This is the peak of the economic cycle. As consumer demand slows, companies scale back their expansion projects and pause hiring. Even before the official declaration of a recession, economists observe a slight uptick in the unemployment rate. This demonstrates the critical role of identifying the peak as the moment the economic trend reverses, which helps policymakers and businesses make timely adjustments to their strategies.
