This paper attempts a first-cut listing of global public goods and international spillover activities, as well as providing some data on their global distribution alongside basic correlational analysis. Few if any goods are “pure” global public goods and there is a spectrum of the extent of spillovers. Some global public goods are not well measured. The listing is far from exhaustive, nor is it based on rigorous selection criteria. But it does suggest considerable diversity in trends, levels and sources of public good and spillover activities.
How much innovation will be needed to meet the United Nations’ Sustainable Development Goals? Our results suggest that (i) best performers are considerably outperforming the average performance at a given income level, suggesting considerable progress could be achieved through policy change but that (ii) the targets set in the SDGs are unlikely to be met by 2030 without very rapid, ubiquitous technological progress alongside economic growth.
This analysis examines the relationship between legal reform and social norms surrounding homosexuality. First, about a fifth of the variation in individual preferences can be explained at a country level. Second, using a difference-in-differences strategy, legalizing homosexuality improves how individuals view the tone of their communities. Third, we provide further evidence supporting a legal origins argument by examining former colonies. We conclude that adopting legal reform can improve societal attitudes.
This paper analyzes six waves of responses from the World Values Survey to understand the determinants of beliefs about women’s roles in society and their relationship with the legal system and outcomes.
