Technological trajectories and R&D for environmental innovation in UK firms

This article reports results of a 1993 questionnaire survey of how UK companies have been innovating technologically in response to environmental pressures. The survey sought to identify factors stimulating UK firms to innovate more environmentally friendly products and processes, and to investigate the changes in R&D activity they have undertaken to facilitate such innovation. In devising the questionnaire and interpreting the results, we have been strongly influenced by the theoretical frameworks developed over the past 15 years which describe technological developments in terms of ‘selection environments’ and ‘technological trajectories’. Useful though such frameworks are, we conclude that they need to be supplemented by concepts derived from the sociology of technology and from studies of corporate strategies.     

Economic Development and Income Distribution: A Cross-National Analysis

Abstract . The relationship between level of economic development and income distribution is analyzed using both a relative measure of income distribution and, for the first time, an absolute measure of income distribution which corrects for purchasing power differences between nations. Cross sectional regression analysis findings indicate support for non-linear relationships both in the total sample of 68 nations, and also in sub-samples of 54 developing nations and 14 industrial democracies. Our findings suggest that the poorest 40 percent of the population lose income both relatively and absolutely in the early stages of economic development. Thereafter there are gains in income although with diminishing marginal returns at the highest levels of development.     

Moving from the lab to the field: Exploring scrutiny and duration effects in lab experiments

The most important issue facing experimental economists is the generalizability of lab results. This letter examines more than 1200 doctor/patient consultations, in which scrutiny and duration of treatment were varied. We show that scrutiny has an important but short-lived effect.     

Do regional economies converge?

Current interest in the new economic growth theory, linked with the development of new, innovative methods of measurement, has resurrected interest in spatial economic convergence. The primary objective of this paper is to examine the extent that regional economies seem to be converging or diverging. It explores the expanding theoretical literature in the field and examines the growing body of empirical evidence that has emerged in recent years not only in the U.S. but also internationally. The paper is retrospective but also embraces new findings relating to the United Kingdom and the U.S., putting particular emphasis on long- and short-term indicators of economic convergence.     

Technical Change in a Model with Fair Wages and Unemployment

This paper uses a variable rate-of-growth model of life-cycle saving as developed by Fry and Mason (1982) to show that demographic factors were behind the rapid rise in saving in Japan, Korea, and Taiwan. The steady decline in the population dependency ratio in an environment of rapid economic growth was the determining factor driving the trend rise in savings in these three countries. Furthermore, demographic trends can also explain the difference in saving ratios in Japan, Korea, and Taiwan. When one compares these countries at the same stage in their development, Koreans did save "little" relative to Japan, but not relative to Taiwan, and this difference in saving can be explained by Korea's higher rate of dependency.

Cross-sectional and time-series momentum returns and market dynamics: evidence from Japan

We test the behavioural theories of overconfidence and underreaction on cross-sectional (CS) and time-series (TS) momentum returns in the Japanese stock markets. Both CS and TS momentum returns are large and significant when the market continues in the same state and turns into losses when the market transitions to another state, consistent with the overconfidence but not the underreaction model. We find that TS conditional momentum returns exceed conditional CS momentum returns because of its active position since TS takes a net long (short) position following UP (DN) markets while CS is a zero-cost strategy irrespective of the market state. Finally, we find no relation between idiosyncratic volatility (IV) and momentum returns which is not supportive of either the overconfidence or underreaction model but implies that IV is not a significant limit to arbitrage in Japan.
