Willingness to take risk depends on whether the risk affects others as well as oneself and on how the risk affects oneś position vis-á-vis others. Taking a bet can improve oneś position relative to others or threaten it. We present an experiment that explores individual attitudes to lotteries...

We study in the laboratory the impact of private information revelation on the selection of partners when forming individual networks. Our experiment combines a "network game" and a "public-good game". In the network game, individuals decide with whom to form a link with, while in the...

We investigate the decision of experimental subjects to incur the risk of revealing personal private information to other participants. We do so by using a novel method to generate personal information that reliably induces privacy concerns in the laboratory. We show that individual decisions to...

This paper deals with the role of reciprocation in the formation of individuals’ social networks. We follow the activity of a panel of bloggers over more than a year and investigate the extent to which initiating a relation brings about its reciprocation. We adapt a standard capital investment...

It has been argued that cognitively constrained consumers respond sub-optimally to complex decision problems, and that firms can exploit these limitations by introducing spurious complexity into tariff structures, weakening price competition. We model a countervailing force. Restricting one's...

Those lecture notes cover the basics of a course in microeconomic theory for MSc students in Economics. They were developed over five years of teaching MSc Economic Theory I in the School of Economics at the University of East Anglia in Norwich, UK.The programme of this course is divided in...

Behavioural and industrial economists have argued that, because of cognitive limitations, consumers are liable to make sub-optimal choices in complex decision problems. Firms can exploit these limitations by introducing spurious complexity into tariff structures, weakening price competition....

We run a laboratory experiment where some participants are selected to make investment decisions on behalf of others. We test whether a democratic context influences the social preferences of decision makers in terms of efficiency, altruism and concern for inequality. We find that decision...

This paper traces the history of TeX, the open source typesetting program. TeX was an early and very successful open source project that imposed its standards in a particularly competitive environment and inspired many advances in the typesetting industry. Developed over three decades, TeX came...
