Francois Bourguignon’s is an interesting companion to Tony Atkinson’s , which I reviewed here recently. It’s a different kind of book, a relatively short argument about why and how to make the globalization process fairer, as contrasted with Atkinson’s longer and detailed description and analysis of inequality in the UK with a substantial list of policy recommendations. It’s useful to have the global picture alongside the national one, however, because the story globally is of much increased incomes in the middle of the distribution in a few countries – largely China – as well as gains among the richest groups.
In the first chapter and its data annexe Bourguignon sets out the figures in careful detail, distinguishing between increases in inequality within countries and changes between countries. “Inequality in the standard of living between countries has started to decline … On the other hand, inequality within many countries has increased.” The book’s central question is then whether these two phenomena are related, linked by the process of globalization, of trade and investment flows between high and low (average) income countries. This is addressed in the second and third chapters of the book. He answers broadly yes, through the far greater intensity of competitive forces operating on industries in the rich economies that couldn’t cope – although he also attributes a significant part of the explanation to the politics of deregulation and tax cuts, and the expanding role of finance.
The final part of the book turns to whether anything ought to be done about inequality in this global context, and if so what can be done. Bourguignon argues that it is worth trying to get the best of both worlds and combine the trend towards less inequality between countries while tackling greater inequality within countries. He rejects the idea of a sharp trade-off between equity and economic efficiency on the grounds that inequality of the degree seen now in the US and UK is politically and institutionally destabilising. Indeed, he says, many aspects of inequality inhibit the efficient operation of markets.
The final chapter turns to policies, and it is the least satisfactory. This is in large part because in a short book like this, there is little room for the persuasive detail. However, I don’t think the policies he favours – more development aid for the poorer economies, taxes and transfers within the rich economies – would be particularly effective. I’m far more in sympathy with Atkinson’s emphasis on market incomes, and the need to address the structures of markets that are the root causes of the increase in inequality.
Having grumbled about that, it is certainly important to keep the biggest of big pictures in mind when thinking about inequality, even at the national level. The fact that the economy is globalized is an important factor in any assessment of the causes of inequality and therefore what it might be practical to do about it.
