“THE retirement-savings crisis is a women’s crisis,” says Sallie Krawcheck, co-founder of Ellevest, a financial-advice firm for women in America. When it comes to retirement income, women are far worse-off than men. The gender pension-gap may be less well-known than the gender pay-gap, but it is in fact far larger.

Among those retired in the EU, women on average receive 39% less in pension income—from state and workplace pensions—than men do (see chart). This puts women at greater risk of old-age poverty. The European Institute for Gender Equality, a think-tank, warned in a study in 2015 that it also makes them more likely to stay with abusive partners. Reforms to European pensions, tying benefits even closer to individual contributions and thus income, mean the gap may widen further.

IN RICH countries, people’s diets are getting worse and they are getting fatter. Hence the increasing popularity of a “fat tax”, to make unhealthy food cost more. Since Hungary led the charge in 2011 with a “chip tax” on fatty and sugary foods, other countries have followed. Britain is to join a long list next year.

Since the poor both spend a higher proportion of their income on food and tend to eat less healthily, they are the main targets of such taxes. In France, for instance, adult obesity is seen in over 20% of households with monthly incomes under €1,500 ($1,765) compared with less than 10% of those who earn over €3,000.

Punishing consumers, however, is politically painful. So “thin subsidies” have been gaining ground. But data on the impact of such policies are scarce. A recent study on the distributional impacts of fat taxes and thin subsidies from researchers at the universities of Oklahoma and Grenoble suggests policymakers should be wary. It...

IN APRIL 1956 the world’s first container ship—the Ideal X—set sail from New Jersey. A year later in Seattle the world’s first commercially successful airliner, Boeing’s 707, made its maiden flight. Both developments slashed the cost of moving cargo and people. Boeing still makes half the world’s airliners. But America’s shipping fleet, 17% of the global total in 1960, accounts for just 0.4% today.

Blame a 1920 law known as the Jones Act, which decrees that trade between domestic ports be carried by American-flagged and -built ships, at least 75% owned and crewed by American citizens. After Hurricane Irma, a shortage of Jones-Act ships led President Donald Trump on September 28th to waive the rules for ten days to resupply Puerto Rico. This fuelled calls to repeal the law completely.

Like most forms of protectionism, the Jones Act hits consumers hard. A lack of foreign competition drives up the cost of coastal transport. Building a...

SWITZERLAND, which developed cross-border wealth-management in the 1920s, was once in a league of its own as a tax haven. Since the 1980s, however, tax-dodgers have been spoilt for choice: they can hide assets anywhere from the Bahamas to Hong Kong. The percentage of global wealth held offshore has increased dramatically. But it has been hard to say how much that is, and who owns it.

Few offshore centres used to disclose such data. But in 2016 many authorised the Bank for International Settlements (BIS) to make banking statistics publicly available. Using these data, a new study by Annette Alstadsaeter, Niels Johannesen and Gabriel Zucman, three economists, concludes that tax havens hoard wealth equivalent to about 10% of global GDP. This average masks big variations. Russian assets worth 50% of GDP are held offshore; countries such as Venezuela, Saudi Arabia and the United Arab Emirates climb into the 60-70% range. Britain and continental Europe come in at 15%, but...

A COMPANY that moves up the value chain from refrigerator parts to cars is impressive but not that surprising. A car company that buys an investment bank is audacious. But Zhejiang Geely Holding Group, a conglomerate based in Hangzhou, China, did not become big by paring its ambitions. Having successfully made the fridge-parts-to-cars transition at home, it went global in 2010. It acquired Volvo, a Swedish carmaker, from Ford of America. Now Geely is back in Scandinavia for another acquisition. This time it is buying one of Denmark’s biggest banks.

Saxo Bank announced on October 2nd that Geely would acquire 51.5% of its shares. It will spend over $800m on the deal, which still requires regulatory approval. Sampo Group, a Finnish insurance company, will acquire 19.9% of Saxo shares for €265m ($311m), and Kim Fournais, Saxo’s co-founder and chief executive, will retain 25.7%. The sellers are Sinar Mas, an Indonesian conglomerate, and TPG, an American private-equity firm....

EVERY market mania reaches a point when pitches to would-be investors enter the realm of the surreal. So it goes for “initial coin offerings”, or ICOs. A new one by a firm called POW invites Facebook users to claim tokens for nothing; when they later become convertible into other tokens, the first to take advantage of the offer could “become worth $124bn…making them the richest person on Earth”, the blurb says. Not a bad return for no money invested and no risk borne. However bizarre, bubbles are hard to resist: no one wants to be the only one of their friends left out. They can also be financially ruinous. But gambling on a craze, even a highly dubious one, can be about more than blind greed.

The ICO boom is an outgrowth of the emerging, occasionally inscrutable world of cryptocurrencies. These are a form of money (bitcoin and ether are examples) used in transactions which are recorded on a distributed public ledger called a blockchain. An ICO is a scheme to raise funds for an...
