Another Post On Glass, This Time With "The Alchemist's Fallacy" (And Professor Nordhaus)

Following up on yesterday's "Dark Crystal: The Secrets of Swarovski".
From FT Magazine's Undercover Economist:

It’s tough turning ideas into gold
‘If innovators make no money at all, they will end up creating for the love of creation rather than for any financial reward’ 
Alchemy, the ancient art of turning base metals into precious ones, was built on more than one misapprehension. The obvious error is that it is impossible to turn lead into gold. (Not quite impossible, actually. Chemistry will not do the job but a particle accelerator will, although not cheaply. In 1980, researchers bombarded the faintly lead-like metal bismuth and created a few atoms of gold. The cost was a less-than-economical rate of one quadrillion dollars an ounce.)

But there is a subtler mistake — not a scientific one but a matter of economics. “The alchemist fallacy” is the belief that once a simple method is found for turning lead into gold, gold will continue to be precious. We don’t have to rely on economic theory to refute this conclusion, because we have a fascinating case study of a close parallel.

Twenty-six million years ago, some cataclysmic event in the Eastern Sahara raised the temperature of silica sand to well over 1,000 degrees. The result was a large deposit of a lustrous material the colour of a lemon’s flesh. A fragment of this precious stuff was used to make jewellery for Tutankhamun’s tomb. (The story is well told in Steven Johnson’s book How We Got to Now.) The substance could be quarried but not manufactured.

While alchemists never figured out how to turn lead into gold, other craftsmen did develop a process with much the same economic implications. They worked out how to transform silica sand, one of the most common materials on earth, into the beautiful, versatile material we know as glass. It has an astonishing variety of uses from fibre optics to microscopes to aeroplane fuselages. But while gold remains highly prized, glass is now so cheap that we use it as disposable packaging for water.

When it was possible to restrict access to the secret of glassmaking, the guardians of that knowledge profited. Venetian glassmakers were clustered together on the island of Murano, where sparks from the furnaces would not endanger Venice itself. Venice had less success in preventing the secrets of glassmaking from spreading. Despite being forbidden on pain of death to leave the state of Venice, some of Murano’s glassmakers sought fortunes elsewhere. The wealth that could be earned as a glassmaking monopolist in some distant city must have been worth the risk.

That is the way of new ideas: they have a tendency to spread. Business partners will fall out and set up as rivals. Employees will leave to establish their own businesses. Time-honoured techniques such as industrial espionage or reverse engineering will be deployed. Sometimes innovators are happy to give their ideas away for nothing, whether for noble reasons or commercial ones. But it is very hard to stop ideas spreading entirely.

A few years ago, the economist William Nordhaus tried to estimate just how fallacious the alchemist fallacy is — how much of the social gains from innovation does the innovator manage to keep hold of? If the answer is anywhere near 100 per cent — even 50 per cent — then there is no fallacy at all. But if the answer is near zero, then innovations are swiftly copied, benefiting competitors and above all consumers.

Nordhaus was writing in the wake of the dotcom bubble, and pointed out that the valuations of “new economy” companies could be justified only if they were able to retain about 90 per cent of their value to society. This is a slice of the pie to make the most powerful and sophisticated monopolist dream. Nordhaus, pointing to the rapid demise of many dotcom firms and the tight margins of others, reckoned that the proportion was rather lower than that.

Looking at data from the United States between 1948 and 2001, Nordhaus estimated that corporations were able to keep about 3.7 per cent of the social value of their innovations. The remaining 96.3 per cent went to everyone else, mostly to consumers.....MORE
Nordhaus is one of the heavyweights of the econ biz and has shown up on our pages a half-dozen times.
We don't always agree with him but he is a heavyweight.

A look at his c.v. turns up at least three Nobel Laureates among his co-authors and he hangs his hat at Yale's Cowles Foundation which also has some Nobelist connections:

Robert Shiller
Tjalling Koopmans
Kenneth Arrow
Gerard Debreu
James Tobin
 Franco Modigliani
Herbert Simon
Lawrence Klein
Trygve Haavelmo
Harry Markowitz

Not as prolific as Cambridge's Cavendish Lab, 29 Laureates, mainly in physics, at last count but then the econ version isn't one of the original Nobels and is much more recent.
