Lecture Notes: Neuroscience and Behavioral Economics

Key Concepts

  • Behavioral Economics: Integrates psychology and social sciences to make economics more reflective of human behavior.
  • Neuroeconomics: Examines brain activity during economic decision-making.

Hypothetical Bias

  • Occurs when individuals overstate their intentions in surveys without real consequences.
  • Example: Discrepancy in reported voting behavior versus actual voting.
  • Marketing implications: Many new products fail due to inaccurate market testing based on hypothetical biases.

Measuring Hypothetical Bias

  • Challenges in quantifying and adjusting hypothetical bias to reflect real behavior.
  • Research involves identifying brain signatures predictive of false affirmative responses ("Yes") that don't translate into action.

Research Methodologies

  1. Brain Imaging Studies

    • Participants were shown images of goods and asked if they would buy them at specific prices.
    • Follow-up with actual purchase decisions after brain scanning to study neural patterns.
    • Specific brain activity correlated with stated intent versus actual purchasing action.
  2. Eye Tracking and Mouse Tracking

    • Eye Tracking: Measures gaze duration and pupil dilation as indicators of interest or arousal.
    • Mouse Tracking: Movement speed and trajectory correlate with valuation and decision certainty.
    • Both methods provided insights into actual versus stated purchase intentions.

Applications and Future Research

  • Smart Vending Machines: Used to study habits and the impact of small price changes.
    • Features a programmable display to test consumer reactions.
    • Potential for using cameras to track consumer focus, particularly on price awareness.

Conclusion

  • The current era is a 'golden age' for social sciences due to diverse measurement technologies.
  • Continued research aims to better understand decision-making processes and refine economic models.
