Synergies or Trade-Offs in University Life Sciences Research

Major legislative, legal, and technological changes paved the way for a period of remarkable growth in the patenting of life science research by U.S. universities in the 1980s and 1990s. Using a multiple-output cost framework and two decades of panel data on ninety-six universities, this article examines whether economies of scope and/or scale are present in university production of three major life science research outputs: journal articles, patents, and doctorates. The results show strong evidence of economies of scale in life science research production with mixed evidence of economies of scope between articles and patents.     

House Money Effects in Public Good Experiments

Are decisions in economics experiments distorted because the money subjects risk comes from the experimenter rather than their own pockets? There is some evidence that people receiving small, one time “windfall gains” have a higher marginal propensity to consume them, and when doing so, exhibit greater risk-seeking behaviour. This has been found in individual decision making experiments when anticipated wealth effects have been controlled, and labelled the “house money effect.” In public good experiments, house money effects could be driving the high levels of voluntary contributions commonly observed. This possibility is tested by comparing VCM contribution rates when subjects supply their own endowments with those when endowments are provided, while holding constant the distribution of promised earnings. No evidence of house money effects is found, suggesting that use of “free” initial money endowments does not distort subsequent contributions in VCM environments.     

HRM as a predictor of innovation

There is growing evidence available to suggest that HR practice is an important predictor of organisational performance. In this article, we argue that HR practices also have the potential to promote organisational innovation. We describe a longitudinal study of 22 UK manufacturing companies and examine the relationship between such practices and product and technological innovation. Results reveal that training, induction, team working, appraisal and exploratory learning focus are all predictors of innovation. Contingent reward, applied in conjunction with an exploratory learning focus, is positively associated with innovation in technical systems. Furthermore, training, appraisal and induction, combined with exploratory learning focus, explain variation between companies in product and technological innovation above and beyond the main effects observed.     

Is the Term Premium a Risk Premium?

This paper explores whether excess holding period returns on long vis-a-vis short-term securities behave in a manner that is consistent with (1) market efficiency, (2) the time-varying-term-premium variant of the expectations hypothesis, and (3) theories of the term premium that view it as a reward for risk bearing. Both traditional and modern theories of the term premium imply that it should evolve fairly slowly over time as attitudes toward risk and/or perceived covariances with wealth or consumption change. This implies that this period's term premium should have some predictive ability for next period's. However, we find that this quarter's ex-post term premium has zero predictive ability. For monthly rates and returns, the evidence is less clear cut, but again the implied term premia do not behave in a manner consistent with existing theories.     

The Role of Community and Farm Characteristics in Farm Input Purchasing Patterns

This work uses unique data from three dairy-dependent communities in rural Wisconsin to test established theory and empirical studies that link farm structure to local purchasing patterns. A theoretical model of purchasing choices is developed to derive the demand determinants of local purchasing. This model is tested empirically across eleven major dairy farm inputs using a double-bounded Tobit model that also includes community characteristics. The empirical estimations find little support for a general linkage between farm-level characteristics and local purchasing patterns. The results do suggest that different community characteristics provide some explanations for diverse purchasing patterns.     

Membership retention in the public sector

Based on a survey of UNISON members, this article examines the reasons underpinning membership retention in the public sector. It shows that collective reasons are central to retention and that packages of financial services have little impact on retention. An article to be published in the next issue of this journal develops the themes raised here by reference to a survey of union leavers.     

An Empirical Model of the Sources of Innovation in the U.S. Manufacturing Sector

This paper estimates a simple model of innovation in the U.S. manufacturing sector and derives summary indicators of product and process innovation. Our empirical work reveals that the drivers of innovation extend well beyond business research and development spending. Capital investment, cutting-edge scientific output from academic institutions, and the growth of the science and engineering workforce all matter. The dynamic structure of our model suggests that policymakers must look beyond the short-term when developing and evaluating innovation initiatives because there can be lags of several years before inputs are fully realized in innovative performance. But simple simulations conducted with our equations indicate that even a modest increase in key innovation inputs reaps significant benefits. JEL Classification O31     

Can information and communication technologies be pro-poor?

There is over 20 years of accumulated cross-country evidence on the link between telecommunications provision and economic growth. Looking at micro-studies from a range of countries including Bangladesh, Botswana and Zimbabwe, there is also some evidence that provision of telephony has a dramatic effect on the income and quality of life of the rural poor. This paper examines cross-country evidence to discover if teledensity (the number of telephones per capita) has a pro-poor growth impact—fostering increased average incomes while reducing inequality. It also examines the impact of telecommunications rollout on quality of life variables including infant mortality and literacy. It finds that, historically, telecommunications rollout has had a positive and significant impact on increasing inequality and little impact on quality of life variables. A reason for this is tested and preliminarily confirmed that rollout has (historically) only benefited the wealthy. The paper will then turn to emerging evidence on the role of the Internet in poverty relief and statistics on the access gap in provision between rich and poor, suggesting that this new ICT will also be a force for income divergence. Using the results of the cross-country analysis on telecommunications, the paper will conclude with a discussion of potential policy responses (such as sector reform and universal access programs) to turn telecommunications from a source of growth that also increases inequality to a source of growth that diminishes it.
