Banning genetically modified (GM) food is just another example of promoters of “incumbent products” seeking to restrict competition argues Calestous Juma in yesterday’s Financial Times:
Take coffee: in the 1500s Catholic bishops demonised coffee as “Satan’s drink” and urged a ban. It was competing with wine. In its defence, Pope Clement VIII proclaimed: “Why, this ‘Satan’s drink’ is so delicious it would be a pity to let the infidels have exclusive use of it. We shall fool Satan by baptising it and making it a truly Christian beverage.”
More than a century later, coffee was pitted against tea as the incumbent English drink. To defeat the competition, King Charles II decreed the banning of coffeehouses in 1675 only to revoke the decision two days before it came into effect.
In Germany, coffee was outlawed or its sale severely restricted for economic reasons. “It is disgusting to notice the increase in the quantity of coffee used by my subjects, and the like amount of money that goes out of the country in consequence. My people must drink beer. His Majesty was brought up on beer, and so were his ancestors,” declared Frederick the Great in 1777.
Historical cases of technological competition were limited in their reach. Today’s global economy demands that governments find ways to ensure that the benefits of new technologies are widely shared. Judicial rulings will safeguard the integrity of international trading rules. But they will not guarantee consumer enthusiasm for products that threaten their settled ways.
Calestous Juma was writting about a WTO finding, published earlier this week, that the current European Union moratorium on GM food crops breaches trade rules, click here for earlier post.
