Except for Arizona and Hawaii, the United States ended this calendar's observance of Daylight Saving Time at 2 a.m. local time today. In a fascinating book titled A Time for Every Purpose: Law and the Balance of Life, Harvard University Byrne Professor of Administrative Law Todd D. Rakoff argues that social regulation of time can and should create more room for people to balance time at work with time away from work.

In the article Losing Sleep at the Market: The Daylight-Savings Anomaly, three financial economists document that in international financial markets, the average Friday-to-Monday return on daylight-savings weekends is much lower than expected, with a magnitude 200 to 500 percent larger than the average negative return for other weekends of the year. This finding is consistent with psychological research about how changes in sleep patterns have impacts on accidents, anxiety, decision-making, judgment, reaction time, and problem solving. In this article Winter Blues: A SAD Stock Market Cycle, financial economists found that the lack of sunlight during winter months tends to depress stock prices across international markets. More recently, the article This is Your Portfolio on Winter: Seasonal Affective Disorder and Risk Aversion in Financial Decision Making reported that people with SAD (Seasonal Affect Disorder) exhibited financial risk aversion that varied across seasons because of their seasonally changing affect. SAD-sufferers had much stronger preferences for safe choices during winter than non-SAD-sufferers, and SAD-sufferers did not differ from non-SAD-sufferers during summer.

In two articles, The Psychophysiology of Real-Time Financial Risk Processing and Fear and Greed in Financial Markets: An Online Clinical Study, Andrew Lo and co-authors find traders who respond with too little or too much emotion tend to be less profitable than traders with middle of the range types of emotional responses. Another article Endogenous Steroids and Financial Risk Taking on a London Trading Floor documents that traders tend to make more money on days when their testosterone levels are higher than average.

All of the above differing strands of empirical research share in common the finding that emotions play important roles in how people arrive at financial judgments and financial decisions. Of course, even just a moment of introspection is enough for us to realize that we are like other people in making emotional judgments and emotional decisions. In the article Who's Afraid of Law and Emotions?, the Herma Hill Kay Distinguished Professor of Law at Boalt Hall Kathryn Abrams and Southestern law school professor Hila Keren analyze the ambivalent reactions by mainstream legal academics to law and emotions scholarship and conclude that part of the reason for such responses is the persistence of rationalist tendencies within the legal academy. 

I have often heard after making a presentation about emotions in financial markets and regulation the view that emotions could matter in non-financial areas of life and law, but emotions in general and happiness in particular are not what business and business law are and should be about. Such a point of view strikes as being wrong and closed-minded. As economist Andrew J. Oswald cogently observes in the opening paragraphs of his article Happiness and Economic Performance: 

"Economic performance is not intrinsically interesting. No-one is concerned in a genuine sense about the level of gross national product last year or about next year's exchange rate. People have no innate interest in the money supply, inflation, growth, inequality, unemployment, and the rest. The stolid greyness of the business pages of our newspapers seems to mirror the fact that economic numbers matter only indirectly.

The relevance of economic performance is that it may be a means to an end. That end is not the consumption of beefburgers, nor the accumulation of television sets, nor the vanquishing of some high level of interest rates, but rather the enrichment of mankind's feeling of well-being. Economic things matter only in so far as they make people happier."

I will expand in a later post on decisions to measure happiness by an increasing number of governments of countries, states, and cities as diverse as Bhutan, England, Guandong province in China, Maryland, and Somerville in Massachusetts. For now, check out:
