Phillipe Legrain has followed up his recent pieces in the Financial Times and Prospect, in which he argues the case for taxing land values, with another in today's Guardian.
I have been a follower of Phillipe's work for some time. He is an excellent economist, and like all the best practitioners of that discipline, always places his economic thinking in the larger context of the real world and the daily experience of ordinary people.
His recent arguments for the economic benefits of immigration, which bravely challenge the unthinking bombast of those who blame the influx of non-Britons for all the country's problems, have been quite inspiring.
And now, it seems, Mr Legrain has come to the conclusion that the taxation of land values has a role to play in preventing another disastrous housing boom, and helping us out of the mess created a financial crisis that was sparked by the previous one.
This is excellent news. Land value Taxation needs all the supporters it can get. When someone of Legrain's repute comes on board, we have cause for celebration.
Just one word of caution though: In today's article he proposes that a tax on land values should be introduced now to
"help curb property speculation, fund new social housing and reduce the budget deficit."
All of these are important aims. But we should remember that the budget deficit is only a pressing problem because the financial markets determine that government borrowing should be kept within certain limits. Britian's current budget deficit would be quite sustainable were it not for the fact that the financial markets are able to hold democratically-elected governments to ransom.
Were the next government to follow Legrain's advice and attempt to plug the deficit with revenue from a tax on land values, you can be sure the markets would take immediate and devastating fright, and the UK would quickly find itself in a position not dissimilar to that of Greece.
This is why I continue to argue that while land value taxation is a crucial part of any economy which aspires to be just, its implementation has to be coordinated internationally so as to neutralise the anti-democratic power of the financial markets.
