How far can efficiency be pursued without sacrificing equity? Do fiscal changes designed to improve incentives necessarily lead to greater inequality of incomes? Does the profitability of 'big business' really reflect economies of scale and scope or is it also a reflection of market power? In addressing these and other key questions, a group of internationally acclaimed economists demonstrates why issues of concentration and inequality in economic life are moving to the top of the political agenda in the 1990s. Drawing upon the pioneering work of Peter Hart, this volume reflects the range of his influence from theoretical examinations of measures of industrial concentration and income inequality, to detailed empirical explorations of changes in concentration over time. The volume includes essays on, among other issues, the Hart measure of income mobility, income distribution in Eastern Europe, the UK state pension scheme, trends in the concentration of UK manufacturing in the 1980s, the EC Merger Control Regulation, corporate research and development strategies and corporate technological specialization in international industries. Industrial Concentration and Economic Inequality will be particularly relevant for government policy makers, social analysts and economists concerned with income distribution and industrial policy.
