We document a divergence in the duration of rule for monarchs in Western Europe and the Islamic world beginning in the medieval period. While leadership tenures in the two regions were similar in the 8th century, Christian kings became increasingly long lived compared to Muslim sultans. We argue that forms of executive constraint that emerged under feudal institutions in Western Europe were ass...

This paper studies early childhood health in India, Bangladesh and Nepal, focusing on inequalities in anthropometric outcomes by religious adherence. India and Nepal have Hindu majorities, while Bangladesh is predominantly Muslim. Results confirm a relative Muslim advantage for children less than 12 months of age in height-for-age and weight-for-age z scores primarily in India, possibly reflect...

The newly emerging branch of research of Computer Science received encouragement from the successors of the Warsaw mathematical school: Kuratowski, Mazur, Mostowski, Grzegorczyk, and Rasiowa. Rasiowa realized very early that the spectrum of computer programs should be incorporated into the realm of mathematical logic in order to make a rigorous treatment of program correctness. This gave rise t...

There are two reasons why medieval logic is of interest to modern logician: One is to see how similar it is to modern logic and the other is to see how different it is. We study three 13th-century works on modal logic and give two examples their views of modal logic differ from modern views of the same: the nature of modality and the truth conditions for modal sentences. Because of the differen...

Using a difference-in-differences framework, we estimate the impact of Ramadan on educational outcomes of Muslim students living in a non-Muslim country. For identification we exploit the fact that the number of Ramadan weeks during the course that we study, varies from year to year, ranging from zero to four. Our main finding is that Ramadan observance has a negative impact on performance; one...

Fetal Malnutrition and Academic Success: Evidence from Muslim Immigrants in Denmark* This paper examines the impact of potential fetal malnutrition on the academic proficiency of Muslim students in Denmark. We account for the endogeneity of fetal malnutrition by using the exposure to the month of Ramadan during time in utero as a natural experiment, under the assumption that some Muslim women m...

The events of September 11 have focused attention on just how bad things can be for women living under the rule of Islamic extremists. The Taliban’s inhumane treatment of women in Afghanistan has led many in the West to conclude that Islam itself defines a subordinate role for women that is incompatible with reproductive choice. In reality, however, Islamic thought is flexible on reproductive m...

Many societies became Muslim gradually, without conquest by Muslim rulers. Explanations of this process typically focus on Muslim traders, proselytizing ‘holy men’, and the conversion of ruling elites, as the limited sources suggest. Yet it cannot be assumed that Islamization always made sense for elites as a power-enhancing stratagem, or that rulers or holy men were willing or able to shape th...
