Today I am writing about the sectoral balances which are derived from the national accounts. A recent article in the Financial Times uses these balances to demonstrate that attempts to reduce the UK public deficit can only be successfully achieved by engineering growth in non-government spending. That is an insight that is core to Modern Monetary Theory (MMT) but typically escapes the understanding of most commentators. The article is interesting because it shows how the sectoral balances – which are accounting statements and thus true by definition – can be interpreted in different ways and influence different policy strategies. But the fundamental understanding you gain from knowledge of these balances is that at present public deficits are here to stay … and if you don’t like them … you better get used to it!
