研究了中世纪埃及和伊拉克非熟练工人工资购买力的长期趋势，并估算人均GDP，发现查士丁尼瘟疫和黑死病导致工资长期高于生存水平，高工资环境促进了伊斯兰黄金时代。
This study establishes long-term trends in the purchasing power of the wages of unskilled workers and develops estimates for GDP per capita for medieval Egypt and Iraq. Wages were heavily influenced by two long-lasting demographic shocks, the Justinian Plague and the Black Death and the slow population recovery that followed. As a result, they remained above the subsistence minimum for most of the medieval era. We also argue that the environment of high wages that emerged after the Justinian Plague contributed to the Golden Age of Islam by creating demand for higher income goods.
