21 Questions
What is the goal of behavioral finance?
To explain and predict behaviors and dynamics in financial markets
What is the efficient market hypothesis (EMH)?
A theory that assumes non-transaction costs, costless information, homogeneous expectations, and rational investors
What are the empirical facts about private households' investment behavior?
Low rates of stock market participation, under diversification, poor trading performance, and investment in costly mutual funds
What is return predictability in financial markets?
Past long-term returns predict future returns with a negative sign, while past medium-term returns predict future returns with a positive sign
What is the equity premium in financial markets?
Stocks have outperformed treasury bonds by about 5% per year
What are bubbles in financial markets?
Episodes where an asset becomes substantially overvalued for a significant period of time, with characteristics such as a sharp price rise and subsequent decline, high trading volume, and positive investor expectations
What are the limits to arbitrage in financial markets?
Fundamental risk, noise trader risk, synchronization risk, and costs of trading and discovery, which can allow mispricing to survive

What is return predictability?
A theory that suggests past long-term returns predict future returns with a negative sign
What is the equity premium?
The rate at which stocks have outperformed treasury bonds over the years
What are bubbles in financial markets?
Episodes where an asset becomes substantially overvalued for a significant period of time
Why do limits to arbitrage exist?
Due to fundamental risk, noise trader risk, synchronization risk, and costs of trading and discovery
What is empirical research in behavioral finance based on?
Surveys and experiments in the lab and field
Study Notes
Behavioral Finance and the Importance of Experimentation
- Controlled variation is necessary for empirical scientific knowledge.
- Randomized trials in experiments avoid selection bias and isolate true causes.
- Exogenous variables that are changed by the experimenter allow for observation of variables that cannot be directly observed in the field.
- The goal of behavioral finance is to explain and predict behaviors and dynamics in financial markets.
- Behavioral finance integrates insights from psychology, sociology, and neuroscience into traditional finance theory.
- Empirical research in behavioral finance includes surveys and experiments in the lab and field.
- Realistic assumptions about individuals' beliefs and preferences are important for improving the psychological realism of traditional finance theory.
- The efficient market hypothesis (EMH) assumes non-transaction costs, costless information, homogeneous expectations, and rational investors.
- Empirical facts show low rates of stock market participation, under diversification, poor trading performance, and investment in costly mutual funds among private households.
- Return predictability shows that past long-term returns predict future returns with a negative sign, while past medium-term returns predict future returns with a positive sign.
- The equity premium shows that stocks have outperformed treasury bonds by about 5% per year, which is difficult to explain.
- Bubbles are defined as episodes where an asset becomes substantially overvalued for a significant period of time, and empirical definitions include several characteristics such as a sharp price rise and subsequent decline, high trading volume, and positive investor expectations.
- Limits to arbitrage exist due to fundamental risk, noise trader risk, synchronization risk, and costs of trading and discovery, which can allow mispricing to survive.
