The causes of the Protestant Reformation have long been debated. This paper seeks to revive and econometrically test the theory that the spread of the Reformation is linked to the spread of the printing press. I test this theory by analyzing data on the spread of the press and the Reformation at...

Using a gift exchange experiment, we show that the ability of reciprocity to overcome incentive problems inherent in principal-agent settings is greatly reduced when the agent’s effort is distorted by random shocks and transmitted imperfectly to the principal. Specifically, we find that gift...

Handbook on Islam and Economic Life is a unique study, one of the first of its kind to consider Islam within a broader economic sphere. Covering a wide breadth of topics and research, it explores how Islam impinges upon and seeks to shape major aspects of economic life including economic...

New technologies have not always been greeted with great enthusiasm. Although the Ottomans were quick to adopt advancements in military technology, they waited for almost three hundred years to allow the first book to be printed in Arabic script. We explain differential reaction to technology...

A vast economic history literature suggests that medieval institutions supporting contract enforcement were necessary for impersonal exchange to emerge. Yet this literature cannot account for the bill of exchange, an important financial instrument that had positive legal standing in both the...

A fundamental question of economic and technological history is why some civilizations adopted new and important technologies and others did not. In this paper, we construct a simple political economy model which suggests that rulers may not accept a productivity-enhancing technology when it...

Why do sudden and massive social, economic, and political changes occur when and where they do? Are there institutional preconditions that encourage such changes when present and discourage such changes when absent? I employ a general model which suggests that cascades which induce massive...

Recent uprisings in the Arab world consist of individuals revealing vastly different preferences than were expressed prior to the uprisings. This paper sheds light on the general mechanisms underlying large-scale social and institutional change. We employ an agent-based model to test the impact...

New technologies have not always been greeted with full enthusiasm. Although the Ottomans were quick to adopt advancements in military technology, they waited almost three centuries to sanction printing in Ottoman Turkish (in Arabic characters). Printing spread relatively rapidly throughout...
