HOW many days does it take to correct a misleading newspaper interview? Four, in the case of Paul Romer, the World Bank’s chief economist. On January 12th a surprising article in the Wall Street Journal alleged that one of the bank’s signature reports—on the ease of doing business around the world—may have been tainted by the political motivations of bank staff. The story was based on an interview with Mr Romer, who pointed out that Chile’s ranking in the yearly report had dropped sharply during the presidency of Michelle Bachelet, a left-leaning politician who took office for the second time in 2014. Chile sank so heavily not because doing business had become harder, but because the bank had repeatedly changed its method of assessment.
That method mostly entails answering measurable questions, such as how many days does it take to start a business, register a property or file taxes. The answers determine a country’s score (known as its “distance to...Continue reading
AS A boy, Antoine Hubert used to catch butterflies. These days, the agro-engineer has eyes only for meal worms. In a demonstration factory near Dole in eastern France, he shows how trayfuls of plump, half-grown worms are fed, left to grow in a darkened dormitory, and then—after two months—slaughtered and cleaned with a blast of steam. A machine divides the resulting mush into oil and protein powder.
Around 70% of a worm is protein, making it ideal for animal feed. Demand is soaring, notably at fish and shrimp farms. Mr Hubert predicts aquaculture businesses will need 70m tons of feed annually in ten years’ time, up from 40m now. The global market for animal feed, he reckons, is already worth €500bn ($610bn).
Ynsect, his firm, thus expects to grow once it opens a new factory this year. He dreams of annual output exceeding 1m tonnes, hinting at a hunger for scale often left unsatisfied in a French entrepreneur: local...Continue reading
THE most distractingly unrealistic feature of most science fiction—by some margin—is how the great soaring cities of the future never seem to struggle with traffic. Whatever dystopias lie ahead, futurists seem confident we can sort out congestion. If hope that technology will fix traffic springs eternal, history suggests something different. Transport innovation, from railways to cars, reshaped cities and drove economic advance. But it also brought crowded commutes. Now, as tech firms and carmakers aim to roll out fleets of driverless cars, it is worth asking: might this time be different? Alas, artificial intelligence (AI) is unlikely to succeed where steel rails and internal-combustion engines failed.
More’s the pity. In America alone, traffic congestion brings economic losses estimated in the hundreds of billions of dollars each year. Such costs will rise unless existing transport systems receive badly needed investment. For example, fixing New York’s beleaguered, overcrowded subway will...Continue reading
IT IS usually considered quaint to predict foreign-exchange movements by reference to whether currencies are dear or cheap. Metrics such as The Economist’s Big Mac index, a lighthearted guide to exchange rates, hint at how far currency values are out of whack. But they are often driven further out of kilter by capital flows, by fear and greed, by the interventions of policymakers, and so on.
Since our last look at the index in July, cheap currencies have narrowed the valuation gap against the dollar—almost completely in case of the Canadian dollar (see chart). Fundamentals, such as fair value, seem (at last) to have greater sway in the foreign-exchange market.
The index is based on the idea of purchasing-power parity, which says exchange rates should move towards the level that would make the price of a basket of goods the same in different countries. Our basket contains only one item, but it is found in around 120 countries: a Big Mac hamburger. If the local cost of...Continue reading
PERHAPS the most vexing thing for those watching the oil industry is not the whipsawing price of a barrel. It is the constant updating of theories to explain what lies behind it. In March 2014, when the price of a barrel of Brent crude was in three figures, the then boss of Chevron, an oil giant, observed that the scarcity of cheap oil meant “$100 per barrel is becoming the new $20”. Two years later, when the oil price slumped below $28, the talk was of a global oil glut caused by the furious efforts of the OPEC cartel to regain market share. Now that oil prices have tested $70, analysts are again scratching their heads.
In “1984”, George Orwell coined the term “doublethink”, the ability to believe two contradictory things. Oil analysis seems to require similar cognitive gymnastics. Three big questions arise. First, why has the oil price more than doubled in the space of two years, against all expectation? Second, why has this surge been met with cheers from global stockmarkets and not...Continue reading
