siders the importance of the family as an institution. Little attention, however, has been given to the impact of the family structure and its dynamics on institutions. This limits our ability to understand distinct institutional developments-and hence growth-in the past and present. This paper supports this argument by highlighting the importance of the European family structure in one of the most fundamental institutional changes in history and reflects on its growth-related implications. What constituted this change was the emergence of the economic and political corporations in late medieval Europe. Corporations are defined as consistent with their historical meaning: intentionally created, voluntary, interest-based, and self-governed permanent associations. Guilds, fraternities, universities, communes, and city-states are some of the corporations that have historically dominated Europe; businesses and professional associations, business corporations, universities, consumer groups, counties, republics, and democracies are examples of corporations in modern societies. The provision of corporation-based institutions to mitigate problems of cooperation and conflict constituted a break from the ways in which institutions had been provided in the past. Historically, large kinship groups-such as clans, lineages, and tribes-often secured the

This paper presents an economic institution which enabled eleventh-century traders to benefit from employing overseas agents despite the commitment problem inherent in these relations. Agency relations were governed by a coalition--an economic institution in which expectations, implicit contractual relations, and a specific information-transmission mechanism supported the operation of a reputation mechanism. Historical records and a simple game-theoretical model are used to examine this institution. The study highlights the interaction between social and economic institutions, the determinants of business practices, the nature of the merchants' law, and the interrelations between market and nonmarket institutions.

This paper integrates game-theoretical and sociological concepts to conduct a comparative historical analysis of the relations between culture and institutions. It indicates the importance of culture, and in particular cultural beliefs, in determining institutions, in institutional path dependence, and in forestalling intersociety successful adoption of institutions. Examination of institutional change in two premodern societies from the Muslim and the Latin worlds yields that their distinct institutional structures resemble those found by social psychologists to differentiate contemporary developing and developed economies. This suggests the historical importance of distinct cultures and the related societal organizations in economic development.

Social institutions were often founded by the elite to avoid social upheavals. Institutions helped mitigate the threat of violent social responses to labor-saving innovations. But their organizational forms were influenced by preexisting cultural and social factors. The differences in Chinese and English social institutions explain why England became the first modern economy. Using an English panel of poor relief and social unrest from 1650 to 1830, we document that poor relief was statistically significant in reducing social disorder. Social instability, in turn, negatively influenced innovations, while innovations were positively and significantly related to poor relief.

The authors interpret historical evidence in light of a repeated-game model to conclude that merchant guilds emerged during the late medieval period to allow rulers of trade centers to commit to the security of alien merchants. The merchant guild developed the theoretically required attributes, secured merchants' property rights, and evolved in response to crises to extend the range of its effectiveness, contributing to the expansion of trade during the late medieval period. The authors elaborate on the relations between their theory and the monopoly theory of merchant guilds and contrast it with repeated-game theories that provide no role for formal organization.
