The recipe for economic growth

Singapore’s GDP per head has eclipsed Britain’s for the past two decades

I am offering my services for a ridiculously modest fee to any poor country keen to double the size of its economy in real (inflation-adjusted) terms over the next 11 years. That means GDP growth of 6.5% a year. For the first five years, I require no payment; then perhaps a tiny 0.1% of GDP for each of the last six years.

There is no great mystery in how to make a low-income economy boom. Ideally, start with a young population, because the old tend to become a state expense and hoard money, hampering GDP growth. Then move most of those people working on the land to the cities (tourist brochures showing charming paddy fields with workers bent double are exemplars of low value-added – the products add little to the economic pile).

Next, allow women to work. Wherever female participation rates have soared so too has the economy. The rate in America doubled to 66% in the 30 years to 1980, its golden era. Add widely available and cheap contraception and half of the workforce has more time to be productive. Wherever women have the choice they have fewer children, which is why over the last 60 years the average global birth rate has fallen from five children per woman to 2.4.

This pattern has allowed many countries to become less poor. The next phase ideally includes minimum expenditure on defence, given its low economic impact; throwing money at infrastructure (especially power, roads and ports); and mass production by semi-skilled workers. To make an economy work at this stage, money spent on education or welfare is a waste. Workers’ and other rights pose a distinct disadvantage; nor is democracy a particularly helpful ingredient.

The formula worked well for the very early movers – England especially, France and Holland at the start of the 19th century, America, Japan and Germany at the end. The latter quarter of the 20th century saw the rise of the Tiger economies in Asia (and a few cubs globally). These four Tigers – South Korea, Taiwan, Hong Kong and Singapore – became role models of how to escape poverty. For two decades Hong Kong and Singapore have enjoyed higher real disposable income per capita than their one-time coloniser, the UK.

Definitions of how this is measured vary considerably and all are clunky. I use a common benchmark – “adjusted net national income per capita in constant 2010 dollars of between $9,000 to $13,000” – because the data provides good comparisons. Yet this must be qualified, as much of it is little more than guesswork. Not only are many GDP measures poorly collated or completely made up (as in the old USSR or China today), but they fail to capture the huge role of the black market, which in countries such as Mexico or Russia is thought to be over 40% of GDP and 20% in Greece and Italy.

In 1960 there were an estimated 101 countries in the middle-income trap (MITs). Of these less than 15 had broken out by 1990; by 2019, only 20. Thus the majority of MITs are locked in the waiting room where most are now doomed to remain. Some will even regress. To advance from poverty to MIT is relatively easy. To become a developed economy requires dramatic changes, almost to the extent of tearing up earlier, successful plans.

Higher wages and better education create their own dynamic, but also lead to a surge in welfare demands. Many MITs fail at this stage. The tax base is insufficient because of the black market and corruption. In early development corruption can be beneficial: the big cheese bribes the leaders to allow him to build factories and roads. The few labour or environment laws or individual rights are weakly enforced. Hong Kong’s success grew out of textiles where all these factors applied.

Many countries have enjoyed rapid growth up to MIT status with a handful of family businesses running the show in a cosy club with money-hungry politicians. It works for a while. It took five years from 1835 to build the London to Bristol Great Western Railway. Many of us will be six feet under by the time HS2 is finished. Yet as economies advance they become more complex, so a transparent legal system with an independent judiciary is vital to referee competing interests. So yes, for all its flaws a form of genuine representative rule is required.

Permanent members of the MIT club tend to share certain characteristics. One is having the same leader in power for over a decade, or the same party for even longer. Examples include Argentina, Brazil, Malaysia and Turkey. In downturns these leaders resort to populism and handouts to supporters. Another hallmark is low investment rates in capital plant and machinery, or in research and development, where MITs spend proportionally less than a third compared with developed countries. Then there is inequality. The Gini coefficient measures how widely wealth is spread: zero represents absolute equality (20th-century communist experiments proved that zero created near universal misery); 100 represents total inequality.

Most developed countries are between 28 and 38; they have a broad consumer base. MIT countries score much higher. The four countries mentioned above, along with Colombia, Mexico, South Africa, and Thailand fall come into this category. Finally there is “leakage”: the fear of seizure by government results in much needed capital at home being squirrelled into offshore sanctuaries – witness the hefty Russian and Chinese ownership of London’s skyline.

These problems mean that many MITs are largely ignored by two overlapping sources of money that otherwise can turbocharge an economy: foreign direct investment (FDI) and multinational corporations (MNCs). FDI can be passive – you and I buy shares in a country’s bonds or equities because we think they look a good long-term investment. MNCs are even more opportunistic. Their investment goes to the country offering the best longer-term bang for their buck; it takes time to get money back from building a factory.

They know “unbeatable deals” from national governments are too good to be true. They want stability. In February I visited Uruguay’s largest business, a giant, Finnish-owned paper mill on the River Uruguay. On the other side is Argentina. It had offered the company knockout terms, but after politicians and businessmen from each municipality, district and central government had demanded their cut, Uruguay came in at half the price.

The problems facing MITs today are stark. The key drivers are stalling. Growth in world trade has been slowing for nearly a decade while barriers and tariffs have been rising. As a result MNCs tend to invest less in these developing nations while FDI is being diverted to safer homes (the largest European recipient of the last decade was the UK). There is excess capacity in many industries. Most important is demographics. The growth rate of the global population has been falling since the 1980s with the birth rate below the replacement rate in diverse countries. The populations of Japan, Italy, France and China are all ageing rapidly, with the attached costs and loss of production. The easy gains have been had; structural reforms have stalled.

This matters to investors because the MIT club and its wannabe members comprise over half the world’s population. If they turn sour we are all affected. Progress in North Africa and the Middle East has ceased. In Latin America the likely winners such as Chile and Uruguay are economic minnows. Forget Russia, while in Asia the dreams of a modern India are turning to dust. Populous countries such as Indonesia are about to reverse, while even the once safe bets of Malaysia and Thailand look economically iffy.
