Flagged for no other reason than it might be provocative or inflammatory to a few atheist bloggers who I know stop by every now & then:

"A pair of Harvard researchers recently examined 40 years of data from dozens of countries, trying to sort out the economic impact of religious beliefs or practices. They found that religion has a measurable effect on developing economies - and the most powerful influence relates to how strongly people believe in hell....

The two collected data from 59 countries where a majority of the population followed one of the four major religions, Christianity, Islam, Hinduism, or Buddhism. They ran this data - which covered slices of years from 1981 to 2000, measuring things like levels of belief in God, afterlife beliefs, and worship attendance - through statistical models. Their results show a strong correlation between economic growth and certain shifts in beliefs, though only in developing countries. Most strikingly, if belief in hell jumps up sharply while actual church attendance stays flat, it correlates with economic growth. Belief in heaven also has a similar effect, though less pronounced. Mere belief in God has no effect one way or the other. Meanwhile, if church attendance actually rises, it slows growth in developing economies"
