Alasdair M. Blair (1997), Professor of International Relations and Head of the Department of Politics and Public Policy at De Montfort University, has explored the history of British Steel since the Second World War to evaluate the impact of government intervention in a market economy. He suggests that entrepreneurship was lacking in the 1940s; the government could not persuade the industry to upgrade its plants. For generations, the industry had followed a piecemeal growth pattern that proved relatively inefficient in the face of world competition.
