Is the spread of prosperity in the interests of citizens of today’s high-income countries? Is globalisation of their economies in their interest?

These distinct questions are raised in my mind by two important columns from Lawrence Summers (“America needs to make a new case for trade” on April 27 and “A strategy to promote healthy globalisation” on May 4). In these, Mr Summers argues that the international economic policies of the US need to be coupled more closely to the interests of its workers. Many Europeans will concur.

This is not to argue that the interests of citizens of high-income countries are more important than those of others. On the contrary, the view that increases in incomes of the poor offset equivalent losses for the rich is morally compelling. But politics is national. Unless or until a global political community emerges, politics will respond only to perceptions of national interest.

In the summer of 1972, as a “young professional” at the World Bank, I went on a mission to South Korea. It was my first experience of something extraordinary: a country that was developing at a breathtaking rate. The country had already enjoyed a decade of economic growth at close to 10 per cent a year. It continued to grow at close to that rate for another quarter of a century.

What struck me about Korea was the determination of its policy-makers to sustain rapid industrialisation. I saw the construction from scratch of the vast Hyundai shipyard at Ulsan that was soon to join the first rank of ship-builders. That bet itself demonstrated something even more remarkable: Koreans’ belief in their country’s ability to achieve global competitiveness.

For the Koreans, exports were both a tool of development and a test of its success. How different this was from east Africa and India, on which I was to work for the following five years. India was almost as sealed from the world economy as it was possible to be. Its annual growth in income per head had fallen in the 1970s to about 1 per cent a year, while industrial productivity seemed to be declining, despite its desperately low level.

The contrast between South Korea’s success and India’s failure was striking. Both used protection and other tools of industrial policy. Yet the orientation of India’s policies was inward-looking and anti-competitive, while that of South Korea was the opposite. In the literature on development and trade, the Korean strategy came to be called “export promotion”, because its economy did not have an overall bias towards the home market.

The contrast between South Korea and India raised the biggest questions in economics: why have some countries succeeded with development and others failed? Why has Korea jumped from poverty to prosperity in a lifetime? Why did India do badly then, but much better recently?

The broad question is the one Erik Reinert states in his title: How Rich Countries Got Rich… and Why Poor Countries Stay Poor. Reinert is a Norwegian professor who now teaches at Tallinn, Estonia. Ha-Joon Chang, a well-known Korean development economist, teaches at Cambridge. But both give strikingly similar answers to this question.
