A pretty good post over at FDV by DertritusCap on the impact on productivity of religion in Muslim countries and the special season of Ramadan.

Reduced working hours is common during Ramadan. A two-hour workday reduction, as occurs in Pakistan and Egypt, brings an estimated 7.7% decrease in the country’s monthly GDP. For countries that only cut an hour of its workday – such as Indonesia and Malaysia – the decrease is around 3.8%.Workers’ productivity tends to decline during Ramadan. A rough figure of decrease in productivity in Muslim majority countries is between 35% and 50%. However, the slowing down of productivity in Ramadan is predictable, meaning the economy can anticipate it."
