This study analyzed whether research collaboration patterns differ across higher education systems based on maturity of the systems, their language, and their geographical region. This study found that collaboration patterns differ across higher education systems: academics in developed systems are more collaborative than their colleagues in developing systems; academics in English-speaking countries are no more collaborative than their colleagues in non-English speaking countries; and academics in European countries are more collaborative internationally than their colleagues in non-European countries. In addition, it was found that publication is not associated with collaboration, either domestically or internationally. This finding implies that collaboration is a different dimension from publication. Finally, the article discusses implications of the findings for evaluation systems. (Contains 4 tables.)

This paper is a macro study on higher education R&D and its impact on productivity growth. I measure the social rate of return on higher education R&D in 17 high-income OECD countries using country level data on the percentage of gross expenditure on R&D performed by higher education, business, and government sectors over the period 1981-2006. Empirical results suggest that lagged R&D performed by higher education is positively affecting productivity growth in all specifications. The long-run propensity of productivity growth to R&D performed by the higher education sector is also found to be positive and significant while it is found be insignificant to business R&D.

The dramatic growth in health expenditures is an important health policy concern worldwide. Therefore, understanding the factors that increase health expenditures provides policy makers with evidence for decision-making. We aim to examine long-term effects of carbon dioxide emission, urbanization rate and GDP per capita on health expenditures. This study investigates the effect of carbon dioxide emission, urban population, and GDP per capita on health expenditure for 21 OECD countries over the period 1992–2018. Panel ARDL Approach and Gengenbach, Urbain and Westerlund Panel Co-integration Test have been used in the article. Test results indicate the long-run relationship among health expenditure and carbon dioxide emission, urban population, and GDP per capita. Effect of carbon dioxide emission (CO2), urban population, and GDP per capita is significant and positive on health expenditure. Rapid economic growths of OECD countries recently and environmental pollution have increased health expenditures in the long term. [ABSTRACT FROM AUTHOR]
