Set 3: Inferences (Advanced)
Explanation
PASSAGE
Behavioral economists have documented 'hyperbolic discounting'—our tendency to prefer smaller immediate rewards over larger delayed ones, even when delay is brief. This explains why people struggle to save for retirement despite knowing its importance. Standard economic models assuming consistent time preferences cannot account for this pattern, necessitating revised theories of rationality.
What does hyperbolic discounting suggest about conventional economic assumptions?
Detailed Explanation
This question asks you to draw a logical conclusion from the text. Standard models 'cannot account for this pattern' = actual behavior deviates from assumed consistency. A valid inference must be supported by evidence in the passage, even if not stated directly. Look for clues in the text that strongly suggest the answer. Avoid conclusions that require assumptions beyond what's written. Valid inferences are strongly supported by multiple pieces of evidence in the text. Be cautious of choices that go too far beyond what the passage actually states. The best inference is the one most directly supported by textual evidence.
Key Evidence:
• "Standard economic models assuming consistent time preferences cannot account for this pattern"
Why others are wrong: B (People 'struggle to save.'), C (People 'prefer smaller immediate rewards' irrationally.), D (Models cannot account for the behavior.).
