Long-term food demand scenarios are an important tool for studying global food security and for analysing the environmental impacts of agriculture. We provide a simple and transparent method to create scenarios for future plant-based and animal-based calorie demand, using time-dependent regression models between calorie demand and income. The scenarios can be customized to a specific storyline ...

An assessment of current available data on income inequality, at global, international and national levels.

Introduction In 2010, the Global Vaccine Action Plan called on all countries to reach and sustain 90% national coverage and 80% coverage in all districts for the third dose of diphtheria-tetanus-pertussis vaccine (DTP3) by 2015 and for all vaccines in national immunization schedules by 2020. The aims of this study are to analyze recent trends in national vaccination coverage in the World Health...

Diabetes is among the biggest of the 21st-century global health challenges. In the U.S. and other high-income countries, thanks to investments in science, dedication to implementing these findings, and measurement of quality of care, there have been improvements in diabetes management and declines in rate of diabetes complications and mortality. This good news, however, is overshadowed by the e...

Using transnational terrorism data from 1980 to 2000, this study empirically examines the relationships between frequency of participation in transnational terrorism acts and economic development and education improvement. We find an inverse U-shaped association between the frequency of various nationals acting as perpetrators in transnational terrorism acts and per capita income in their respe...

One typically observes differing trends in the distribution of gross incomes across countries. Where do these inequalities originate from? We consider a simple model where individuals have identical preferences but different abilities, and we investigate the impact on the distribution of gross income of changes in the way abilities are distributed among the individuals. Journal of Economic Lite...

We use a firm-CEO assignment framework to model the market for CEO effective labor. In the model’s equilibrium more talented CEOs match with and supply more effort to larger firms. Taxation of CEO incomes affects the equilibrium pricing of CEO effective labor and, hence, spills over and affects firm profits. Absent the ability to tax profits or a direct concern for firm owners, a standard presc...
