We model networks of relational (or implicit) contracts, exploring how sanctioning power and equilibrium conditions change under different network configurations and information transmission technologies. In our model relations are the links, and the value of the network lies in its ability to...

This paper reviews a number of recent contributions that demonstrate that a blend of welfare economics and statistical analysis is useful in the evaluation of the citations received by scientific papers in the periodical literature. The paper begins by clarifying the role of citation analysis in...

This paper explains why people value self-confidence, and how this concern shapes their informational strategies and intertemporal decisions. The theory has applications in areas as diverse as labour supply, savings and investment, or education and career decisions. People generally have...

This Paper studies the internal commitment mechanisms or ‘personal rules’ (diets, exercise regimens, resolutions, moral or religious precepts, etc.) through which people seek to achieve self-control. Our theory is based on the idea of self-reputation over one’s willpower, which potentially...

The main aim of this paper is to demonstrate that a blend of welfare economics and statistical analysis is useful in the evaluation of the distribution of the citations received by scientific papers in the periodical literature. The paper begins by reviewing the connection between basic...

Implementing incentive systems can sometimes backfire in practice: experimental evidence and folklore both suggest that offers of explicit rewards can expose surprising discontinuities in behaviour. This Paper models two such discontinuities that have been claimed by psychologists and...

This paper studies the interactions between an individual's self-esteem and his social environment - in the workplace, at school, and in personal relationships. Because a person generally has only imperfect knowledge of his own abilities, people who derive benefits from his performance (parent,...

This paper draws on a natural experiment to identify the relationship between income and trust. We use a unique panel dataset on Russia where GDP experienced an 8 percent drop in 2009. The effect of the crisis had been very uneven among Russian regions because of their differences in industrial...

We present a tractable stochastic endogenous growth model that explains how social capital influences economic development. In our model, social capital increases citizens' awareness of government activity. Hence, it alleviates the electoral incentives to under-invest in education, whose returns...

Recent Eurobarometer survey data are used to document and explain the stock of social capital in 27 European countries. Social capital in Central and Eastern Europe – measured by civic participation and access to social networks – lags behind that in Western European countries. Using...
