The historiography of British economic performance in the twentieth century has undoubtedly undergone a dramatic shift in the last decade or so. During the 1970s and the early 1980s, in particular, assessments were extremely critical, giving the impression that the British economy would soon be sinking to the ranks of the Third World. The move to a less critical judgment seems to have come with the shift of attention towards levels of productivity rather than simply growth rates. Following important papers in 1986 by Moses Abramovitz in the Journal of Economic History and by William Baumol in the American Economic Review, economic historians and economists have increasingly recognized the inverse relationship between initial levels of productivity and subsequent growth rates. Slow growth during the post-World War II period in countries such as Britain and the United States, can now be understood in terms of the relatively high starting levels of productivity. But there is a danger in the British case of Panglossian overstatement. For whereas the United States has remained the world productivity leader, Britain has not only been caught up by most West European countries, but has also fallen behind. The lag may not be as great as was once feared, but it should not be ignored. One way of guarding against the Panglossian view is to take account of the variation in performance across sectors, and to identify the poor performers that can be seen as holding back Britain's aggregate productivity growth. Since this book aims to refute the commonly held view that public enterprise performed badly in postwar Britain, there is a danger that it could be seen as contributing to the Panglossian view.

Iordanoglou attempts to defend Britain's public enterprise by comparing labor productivity growth between 1954 and 1979 in a sample of five public industries with labor productivity growth in a sample of twenty-nine private industries over the same period. The sample is selected on the basis of (1) market expansion, as measured by the increase in the nominal value of sales, (2) plant size and, (3) investment expenditure per employee measured over ten years in current prices. The effect of this is to produce a much narrower study than might be expected from the introduction. It must be emphasized that (1) since the study is limited to expanding industries, there is no attempt to defend the performance of declining public industries such as coal or the railways, (2) the analysis is limited to labor productivity, with no assessment of total factor productivity, (3) the analysis stops in 1979 before the privatization program and productivity improvements of the 1980s and, (4) the large-scale, capital-intensive, heavy industry that public enterprise is compared with has traditionally been seen as an under-performing part of British private industry. This is a fairly limited defense, then, but even this is not really convincing if we take account of the catching-up perspective. For although labor productivity growth was a bit faster in the public industries than in the private industries, the initial labor productivity difference between Britain and the United States was much greater in the public industries. This means that the opportunity for catching-up growth was greater in the public industries.

Iordanoglou's defense of Britain's public enterprise is unconvincing, then, but there is another potential use for the book -- as a source of data. Here, however, it is unfortunate that the data are presented in a less than ideal way. The first problem is that the use of a sample means that the data appendices that make up nearly half of the book are a seriously incomplete reference source. The manufacturing data are anyway available for the full sample of industries and including capital and TFP growth as well as labor productivity growth for a longer period in Nicholas Oulton and Mary O'Mahony's, Productivity and Growth: A Study of British Industry, 1954-1986 (Cambridge University Press, 1994). The second problem is that, as already noted, the sample stops in 1979. This is not only a long time ago, but is also just before the privatization program that has been accompanied by dramatic changes in productivity performance. It is hard to see many economists or historians being content with a data set that stops at this crucial point in time.
