Labor Market Demand for Lecturers

Steps:

• Identify wages as determined by supply and demand in the labor market for lecturers.
• Consider how each option affects demand for lecturers or supply of labor.
• Evaluate shifts: increased student demand raises lecturer demand, while others impact supply or unrelated factors.
• Select the option that directly boosts lecturer demand, leading to higher wages.

Why D is correct:

• Increased student demand for university shifts the demand curve for lecturers rightward (law of supply and demand), raising equilibrium wages.

Why the others are wrong:

• A: Tuition fee increases may fund universities but do not directly increase lecturer demand.
• B: Fringe benefits are non-wage compensation, not affecting base wages.
• C: Shorter training increases lecturer supply, lowering wages via leftward supply curve shift.

Final answer: D
