The informal sector accounts for a substantial fraction of employed population in Mexico and other Latin American countries.

Early 2009 saw the emergence of an H1N1 influenza epidemic in North America that spread to eventually become a global pandemic. Previous work has suggested that pandemics can have large macroeconomic effects on highly affected regions; here we estimate what those effects might be for Australia....
