"In finance, as in physics, a good theory should be simple and beautiful."
This quote suggests that the principles of finance and physics share similarities, particularly in the quality of theories. A good theory, whether it's about the movement of particles in physics or the behavior of financial markets, should be not only accurate but also simple and aesthetically pleasing to understand. The simplicity and beauty in a theory make it easier for others to comprehend and apply its concepts, thus contributing significantly to progress in the respective fields.
"I think it's important to understand that finance is a science, not an art."
This quote by Robert F. Engle emphasizes that finance should be approached as a systematic, methodical discipline based on empirical evidence and statistical analysis rather than relying solely on intuition or subjective judgment (art). The implication is that financial decision-making should be rooted in rigorous research, quantitative analysis, and a deep understanding of financial principles to ensure sound and effective outcomes.
"Econometrics is applied mathematics, and like all of mathematics, it involves both beauty and power."
Robert F. Engle's quote emphasizes that econometrics, a branch of economics dealing with statistical methods for analyzing economic data, is not just a set of mathematical tools but also an aesthetic discipline. He suggests that, like mathematics in general, it has both an artistic (beauty) and functional (power) aspect. The beauty lies in its abstract principles, theories, and models, while the power comes from its ability to make predictions, analyze economic phenomena, and inform policy decisions.
"The time-series properties of financial returns are among the most fascinating aspects of finance."
This quote emphasizes that one of the intriguing features of finance is the time-dependent characteristics of financial returns, often referred to as 'time-series properties.' It suggests that understanding how these properties evolve over time can provide valuable insights into the behavior and trends of financial markets. These properties may include auto-correlation (the tendency for returns on a given asset or market to be similar in consecutive periods), heteroscedasticity (volatility changes with the level of returns), or seasonality (recurring patterns in return distributions at specific time intervals). Analyzing these properties helps financiers forecast future market movements, manage risk, and make informed investment decisions.
"I have always believed that econometrics can contribute much to our understanding of finance, if only we are willing to make the effort to do it right."
This quote emphasizes the potential power of econometrics – a statistical method used in economics to study relationships among economic variables – in deepening our understanding of finance. Engle suggests that the key lies in properly applying econometric techniques, indicating that careful, meticulous work is necessary for meaningful insights into financial systems and behaviors.
The advantage of knowing about risks is that we can change our behavior to avoid them. Of course, it is easily observed that to avoid all risks would be impossible; it might entail no flying, no driving, no walking, eating and drinking only healthy foods, and never being touched by sunshine. Even a bath could be dangerous.

If the Chinese economy can be opened so that currencies are convertible, Chinese tourists can take money and go see the world. Chinese businessmen can go and buy property in the U.S. and France and every place. All of a sudden, it's just going to be a blossoming global economy. I think it's going to be good for everybody.

My mother says that my father truly enjoyed having a son. My two-years-younger twin sisters felt that he didn't quite know how to enjoy them. But I wasn't aware of those things then. So many of my childhood memories involve him. All the excursions into science were shaped by his knowledge and enthusiasm.
