Widely published on issues concerned with economics and peace studies, Neild is also the author of the essential The English, The French and the Oyster. Written on his retirement and spurred by a holiday in France, this is a historical-economic exploration of relative prices of oysters in Britain and France and the political and economic origins of these. He has also written Public Corruption: The Dark Side of Social Evolution (Anthem Press).
Among memorable recent quotes, Neild, rebuffing Blair’s claims about Sadam Hussein's alleged biological weapons, wrote: 'To say that the UN inspectors found "enough to have killed the world's population several times over" is equivalent to the statement that a man in his prime can produce a million sperm any day, therefore he can produce a million babies a day. The problem in both cases is that of delivery systems.' (Financial Times, 16 February, 1998)
