In the paper titled "Behavioral Finance -- Asset Prices Predictability, Equity Premium Puzzle, Volatility Puzzle: The Rational Finance Approach," authors Svetlozar Rachev, Stoyan Stoyanov, Stefan Mittnik, Frank J. Fabozzi, and Abootaleb Shirvani address three main objections of behavioral finance to the theory of rational finance. These objections are considered as anomalies that the theory of rational finance cannot explain: predictability of asset returns, the equity premium puzzle, and the volatility puzzle. The authors offer resolutions to these objections within the framework of rational finance by proposing statistical models that can be used without relying on behavioral finance assumptions when searching for explanations for these anomalies. It is important to note that while they provide possible explanations for these anomalies, they do not claim that their proposed resolutions are the only ones. This paper provides valuable insights into understanding and addressing some key challenges in financial theory. By offering alternative explanations within a rational framework it contributes to expanding our understanding of asset pricing and market behavior. The findings presented in this paper have implications for both academics and practitioners in the field of finance.

The paper talks about three problems in how we understand money: knowing how much money we will make from investments, why some investments are riskier than others, and why the value of things can change a lot. The authors suggest using math to help solve these problems. They say their ideas are not the only answers, but they can help us learn more about money and how it works. This is important for people who study money and for people who work with money."
Definitions
- Predictability: being able to guess or figure out what will happen in the future.
- Asset returns: the amount of money you make or lose from an investment.
- Equity premium puzzle: a question about why some investments that seem risky actually make more money than safer ones.
- Volatility puzzle: a question about why the value of things can change a lot even if nothing big happens.
- Anomalies: things that don't fit with what we expect or understand.
- Framework: a way of thinking or organizing ideas.
Behavioral Finance: Asset Prices Predictability, Equity Premium Puzzle, Volatility Puzzle: The Rational Finance Approach
In the paper titled "Behavioral Finance -- Asset Prices Predictability, Equity Premium Puzzle, Volatility Puzzle: The Rational Finance Approach," authors Svetlozar Rachev, Stoyan Stoyanov, Stefan Mittnik, Frank J. Fabozzi and Abootaleb Shirvani address three main objections of behavioral finance to the theory of rational finance. These objections are considered as anomalies that the theory of rational finance cannot explain: predictability of asset returns, the equity premium puzzle and the volatility puzzle.
Predictability Of Asset Returns
The authors propose a resolution to this anomaly within a framework of rational finance by introducing statistical models which can be used without relying on behavioral assumptions when searching for explanations for these anomalies. They suggest that asset prices may be predictable due to factors such as market liquidity constraints or investor sentiment which can cause deviations from fundamental values in certain situations.
Equity Premium Puzzle
The authors offer an explanation for this anomaly by proposing that investors may have different risk preferences which could lead them to demand higher expected returns from stocks than bonds in order to compensate for their higher riskiness. This would explain why stock returns tend to exceed bond returns over long periods of time despite having similar levels of riskiness.
Volatility Puzzle
The authors propose a resolution for this anomaly by suggesting that it could be explained by differences in investor preferences between high-volatility and low-volatility assets. Investors may prefer low-volatility assets because they provide more stable returns while still offering some potential upside if markets move favorably towards them. This preference could lead investors to demand higher expected returns from high-volatility assets in order to compensate for their greater uncertainty and potential downside risks associated with them compared to lower volatility assets.
Conclusion
This paper provides valuable insights into understanding and addressing some key challenges in financial theory. By offering alternative explanations within a rational framework it contributes to expanding our understanding of asset pricing and market behavior. The findings presented in this paper have implications for both academics and practitioners in the field of finance as they provide possible resolutions which do not rely on behavioral assumptions when attempting to explain anomalies such as predictability of asset prices, equity premium puzzles or volatility puzzles within a rational framework instead .
