[…] Swing music, also known as swing jazz or simply swing, is a form of jazz music that developed in the early 1930s and became a distinctive style by 1935 in the United States. Swing uses a strong rhythm section of double bass and drums as the anchor for a lead section of brass instruments such as trumpets and trombones, woodwinds including saxophones and clarinets, and sometimes stringed instruments such as violin and guitar, medium to fast tempos, and a “lilting” swing time rhythm. The name swing came from the phrase ‘swing feelwhere the emphasis is on the off-beat or weaker pulse in the music (unlike classic music). Swing bands usually featured soloists who would improvise on the melody over the arrangement. The danceable swing style of bandleaders such as Benny Goodman and Count Basie was the dominant form of American popular music from 1935 to 1945. The verb “to swing” is also used as a term of praise for playing that has a strong rhythmic “groove” or drive. […] from Wikipedia (link).

I met Death today. We are playing chess. (…) My life has been a futile pursuit, a wandering, a great deal of talk without meaning. I feel no bitterness or self-reproach because the lives of most people [plague] are very much like this. But I will use my reprieve for one meaningful deed.”, Antonius Block.

The Seventh Seal (Det sjunde inseglet). Written and directed by Ingmar Bergman, Sweden 1957 – (…) Disillusioned knight Antonius Block and his squire Jöns return after fighting in the Crusades and find Sweden being ravaged by the plague. On the beach immediately after their arrival, Block encounters Death, personified as a pale, black-cowled figure resembling a monk. Block, in the middle of a chess game he has been playing alone, challenges Death to a chess match, believing that he can forestall his demise as long as the game continues. Death agrees, and they start a new game. The other characters in the story do not see Death, and when the chess board comes out at various times in the story, they believe Block is continuing his habit of playing alone. (…)

(…) In the confessional, the knight says “I use a combination of the bishop and the knight which he hasn’t yet discovered. In the next move I’ll shatter one of his flanks.” Death (in disguise as the priest) replies “I’ll remember that.” When they play by the beach, the knight says: “Because I revealed my tactics to you I’m in retreat. It’s your move.Death captures his opponent’s knight. “You did the right thing“, states the knight, “you fell right in the trap. Check! Don’t worry about my laughter, save your king instead.Death‘s response is to lean over the chess board and make a psychological move. “Are you going to escort the juggler and his wife through the forest? Those whose names are Jof and Mia and who have a small son.” “Why do you ask?” says the knight. “Oh, no reason”, replies Death“.

You have much probably noticed by now how is emerging as a powerful platform for those collecting interesting research papers. There are several good examples, but let me stress one entitled “Bounded Rationality and Beyond” ( web page) curated by Alessandro Cerboni (blog). On a difficult research theme, Alessandro is doing a great job collecting nice essays and wonderful articles, whenever he founds them. One of those articles I really appreciated was John Conlisk‘s “Why Bounded Rationality?“, delivering into the field several important clues, for those who (like me) work in the area. What follows, is an excerpt from the article as well as part of his introductory section. The full (PDF) paper could be retrieved here:

In this survey, four reasons are given for incorporating bounded rationality in economic models. First, there is abundant empirical evidence that it is important. Second, models of bounded rationality have proved themselves in a wide range of impressive work. Third, the standard justifications for assuming unbounded rationality are unconvincing; their logic cuts both ways. Fourth, deliberation about an economic decision is a costly activity, and good economics requires that we entertain all costs. These four reasons, or categories of reasons, are developed in the following four sections. Deliberation cost will be a recurring theme.

Why bounded rationality? In four words (one for each section above): evidence, success, methodology, and scarcity. In more words: Psychology and economics provide wide-ranging evidence that bounded rationality is important (Section I). Economists who include bounds on rationality in their models have excellent success in describing economic behavior beyond the coverage of standard theory (Section II). The traditional appeals to economic methodology cut both ways; the conditions of a particular context may favor either bounded or unbounded rationality (Section III). Models of bounded rationality adhere to a fundamental tenet of economics, respect for scarcity. Human cognition, as a scarce resource, should be treated as such (Section IV). The survey stresses throughout that an appropriate rationality assumption is not something to decide once for all contexts. In principle, we might suppose there is an encompassing single theory which takes various forms of bounded and unbounded rationality as special. cases. As with other model ingredients, however, we in practice want to work directly with the most convenient special case which does justice to the context. The evidence and models surveyed suggest that a sensible rationality assumption will vary by context, depending on such conditions as deliberation cost, complexity, incentives, experience, and market discipline. Beyond the four reasons given, there is one more reason for studying bounded rationality. It is simply a fascinating thing to do. We can mix some Puck with our Hamlet.
