We use city-level data from the daily air pollution index and meteorological data on wind movement to see whether air pollution in China spills over from one city to another.

Even though antiretroviral treatment is becoming more efficient and available, new HIV infections still occur, and this is particularly evident in the sub-Saharan Africa region. Heterosexual intercourse is still the main mode of HIV transmission in the region, and multiple and concurrent sex partners are arguably crucial for the spread of the epidemic.

Using a unique city-level panel on the daily air pollution index (API) and fine-scale meteorological data from 2009 to 2013 in China, we examine the existence and the magnitude of spatial spillover effects of urban air pollution in Chinese cities.

In this article we present results from the Cape Area Panel Study investigating
how income comparisons affect the subjective well-being of young adults and parents.

A driving restriction policy, as one of the control-and-command rationing measures, is a politically acceptable policy tool to address traffic congestion and air pollution in some countries and cities in the world. Beijing is the first city in China to implement this policy.

Even though antiretroviral treatment is becoming more efficient and available, new HIV infections still occur. This is particularly the case in sub-Saharan Africa.

This study measures the link between expected health and contextual health uncertainty on sexual behaviours associated with the risk of HIV infection. We extend similar studies on the subject by focusing on contextual factors as a way of explaining individual sexual behaviour in low and high HIV infection areas across sub-Saharan Africa.
