Economics serving society

Graph | When urban density does not bring about productivity: the role of air pollution | P. Champalaune

Dense cities are considered both “greener” since they would emit less CO2 per capita and more productive, since they would allow agglomeration economies (infrastructure sharing, technological spillovers...).

However, urban density also induces higher local pollution, which reduces overall productivity.

Through this graph, Pascale Champalaune deciphers this phenomenon and proposes solutions to remedy this problem.
