Implementation theory assumes that participants’ choices are rational,in the sense of being derived from the maximization of a contextindependent preference. The paper investigates implementation under complete information when the mechanism designer is aware that individuals suffer from...

In this paper, we argue that an important function fulfilled by intermediaries is to facilitate trust by enabling social pressure towards the enforcement of informal agreements. To that end, we develop a new model that uses network theory to show that intermediaries who have exclusivity over a...

We study the evolutionary robustness of strategies in innitely repeated prisoners' dilemma games in which players make mistakes with a small probability and are patient. The evolutionary process we consider is given by the replicator dynamics. We show that there are strategies with a uniformly...

All since the rise of the first civilizations, economic development has been closely intertwined with the evolution of states. In this paper, we contribute to the literature on state history and long-run economic development in four ways. First, we extend and complete the state history index...

This research examines the economic origins and spread of Islam in the Old World and uncovers two empirical regularities. First, Muslim countries and ethnic groups exhibit highly unequal regional agricultural endowments. Second, Muslim adherence is systematically higher along the pre-Islamic...

The business model of companies such as Facebook, MySpace, and Twitter, relies on mon- etizing the information on the interactions and in uences of their users. How valuable is such information, and is its use benecial or detrimental for consumer welfare? We study these questions in a model...

This research establishes that migratory distance from the cradle of anatomically modern humans in East Africa and its effect on the distribution of genetic diversity across countries has a hump-shaped effect on nighttime light intensity per capita as observed by satellites, reflecting the...

Harsanyi (1974) criticized the von Neumann-Morgenstern notion of a stable set on the grounds that it implicitly assumes coalitions to be shortsighted in evaluating their prospects. He proposed a modification of the dominance relation to incorporate farsightedness. In doing so, however, Harsanyi...

We conduct a laboratory experiment to study how demand for redistribution of income depends on self-interest, insurance motives, and social concerns relating to inequality and efficiency. Our choice environments feature large groups of subjects and real world framing, and differ with respect to...

This research explores the biocultural origins of human capital formation. It presents the first evidence that moderate fecundity was conducive for long-run reproductive success within the human species. Exploiting an extensive genealogy record for nearly half a million individuals in Quebec...
