Preferences and the labour supply of married women

The paper reports the main results of using British cross-section data to estimate a labour supply function in which preference variables are interacted with terms measuring the slope and position of the budget constraint.     

Some fallacies in futures research

Can we study the future “rationally” and “scientifically”? This paper examines the methods now in use and finds the assumptions shaky, the tools faulty, and the implications dangerous. With data as the driver, analysis the watchword, quantification the rule, and model-building the prime preoccupation, futurology rests heavily on two key pillars, the information base and cost/benefit calculations. Because these are shown to rest on quicksand, the elaborate methodological structure based on them totters precariously.     

THE DETERMINANTS OF THE INTER-INDUSTRY PATTERN OF DIVERSIFICATION BY U.K. MANUFACTURING ENTERPRISES*

Evidence of the diversity of output of larger U.K. manufacturing enterprises’in 1958, 1963 and 1968 is provided in the Reports on the Census of Production. The Censuses show that between 1958 and 1968 diversification was a significant and general trend in manufacturing industries and an important element in the growth of firms during the period. Moreover diversification seems to be part of a longer term trend in U.K. industry and part of the typical development pattern of the large firm. A theory of the firm's diversification decision is proposed and from this theory predictions are made of the structural features both of a firm's primary industry and of outside industries which are likely to encourage diversification from the one industry to the other. The power of the model in explaining the pattern of diversification between SIC manufacturing orders in the period 1963–68 is weak, due in part to the wide variety of factors influencing diversification and to the aggregated form of the data. Nevertheless, the results show the importance of research and development effort in encouraging diversification and the stimulus to diversification given by profitability and risk in firms’primary industries and high rates of output growth in outside industries. While the findings offer no clear conclusions regarding the impact of diversification upon economic performance, the results are consistent with the propositions that (i) diversification encourages technical progress in industry and (ii) diversification increases the efficiency with which resources are allocated between industries.
