This paper systematically analyses and enriches the observational learning paradigm of Banerjee (1992) and Bikhchandani, Hirscleifer, and Welch (1992).

In this paper, we derive a general Hajek-Renyi type inequality for vector-valued martingales. Several well known inequalities are shown to be special cases of this general inequality. We also derive a similar inequality for dependent sequences. We then apply the inequality to the problem of...

The paper provides a general analysis of the types of models with E-Perturbations which have been used recently to discuss the evolution of social conventions. Two new measures of the size and structure of the basins of attraction of dynamic systems, the radius and coradius, are introduced in...

Social commentators from William Julius Wilson to Charles Murray have argued that increased sorting people into internally homogeneous neighborhoods, schools, and marriages is spurring long- run inequality. Calibration of a formal model suggests that these fears are misplaced.

This paper has pushed Becker's matching insights into a quite plausible search setting. Exploiting the implicit integral equation (10), we gave a thorough characterization of cross-sectional matching patterns in the equilibrium and constrained s ocial optimum of a frictional matching model. In...

Happiness research is on the rise, but is confounded by competing definitions of subjective well-being based on co-existing concepts, resulting in differing measures and giving rise to different potential policy applications. This paper motivates the societal necessity for using well-being...
