This report is not a thesis for the degree of Ph. D. but is an
"exposition" referred to in Regulation 14-9 of the Institute, which
allows the presentation of published work on one particular theme,
instead of an original thesis. The publications submitted with this
exposition are the reports of four studies of the evolution of concentration
in the United Kingdom - (i) in paper manufacture and conversion,
(ii) certain parts of the textile industry, (iii) selected vehicle
accessories and (iv) press and general publishing. These studies
were undertaken under contract for the Commission of the European
Communities and form part of an extensive research programme directed
by the Directorate General for Competition. The four projects were
undertaken over the period April 1974 to November 1977.
For the first of these projects a full-time research associate
(Mrs. W. Hull) was employed. She was responsible for most of the
data collection and prepared the first draft of much of this report.
The other three projects were my own exclusive responsibility and the
texts of the reports were entirely written by me - assistance being
confined to clerical staff for data collection and a research assistant
for data processing. Mr. Robert Cornu negotiated the first two of
the contracts and assisted in communication with the predominantly
French-speaking liaison staff in Brussels but he was not involved in
any of the actual investigations.
The four projects were undertaken in accordance with guidelines
prescribed by the Directorate General for Competition. These guidelines
changed over the 1974-7 period and this is reflected in the reports.
Because the statistical framework and methods of analysis were defined
by the Commission, the investigations and the reports do not entirely
reflect my own views on the analysis of concentration. For this
reason this exposition of the work is of somewhat greater length than
that which Regulation 14-9 appears to imply.
Chapter One contains an explanation of the Commission's interest in
concentration as an aspect of market dominance, followed by summaries
of the relevant literature and of empirical research into the effects
of concentration. The objective of this chapter is to place the
studies financed by the Commission into the context of economic
theory and recent research by industrial economists. Chapter Two
examines problems of definition and of sample design in investigations
of this kind. Chapter Three presents and compares indices of concentration
based on the entire sample of firms. Chapter Four is
concerned with the statistical analysis of oligopoly and concentrates
particularly upon the innovative parts of the Commission's methodology.
Chapter Five is a preliminary assessment of the value of the studies
and contains some tentative suggestions for changes in the existing
approach.
Throughout this exposition I have drawn evidence from the four
reports but have only occasionally quoted from any, of the large
number (over 100) reports completed by other research organisations
in the nine member countries of the European Economic Community. I
have estimated the total cost of this research programme at December 1977
prices and up to that date to be around £1.2 millions. |
