the backward bending supply curve of labour indicates?

Step 1: Analyze the question The question asks what a backward-bending supply curve of labour tells us about labour supply.

Step 2: Explain the concept Normally, the law of supply says that as the price rises, quantity supplied rises. For labour, the "price" is the wage rate.

• At low wages, workers offer more hours as the wage rises, because working becomes more rewarding (the substitution effect). The curve slopes upward.
• Beyond a certain wage, workers already earn enough, so they prefer more leisure and work fewer hours (the income effect outweighs the substitution effect). The curve bends backward.

So at high wage levels, a higher wage leads to a lower quantity of labour supplied. This is the opposite of the normal law of supply, so it is regarded as an abnormal (atypical) supply situation.

Step 3: Check each option

• A. An abnormal supply situation: Correct. Supply falls even though the price (wage) rises, which contradicts the usual pattern.
• B. The law of supply: Wrong. The law says price and quantity supplied move in the same direction, and the backward bend violates this.
• C. Labour supply and wage are directly related: Wrong. This is true only on the upward part of the curve. The bending back shows an inverse relationship at higher wages.
• D. Uniform elasticity of supply: Wrong. The elasticity changes along the curve and even becomes negative on the backward-bending part.

Step 4: Answer The correct option is A. an abnormal supply situation.

Tip: Remember "backward bend = abnormal supply". Whenever a supply curve slopes downward or bends back, think "exception to the law of supply". Link it to the income effect: when people are rich enough, they choose leisure over extra work.
