Implementation theory tackles the following problem: given a social choice correspondence, find a decentralized mechanism such that for every constellation of the individuals’ preferences, the set of outcomes in equilibrium is exactly the set of socially optimal alternatives (as specified by the correspondence). In this paper we are concerned with implementation by mediated equilibrium; under s...
We study the political economy of social insurance with double heterogeneity of voters (i.e., different income and risk levels). Social insurance is financed through distortionary taxation and redistributes across income and risks. Individuals vote over the extent of social insurance, which they can complement on the private market. Private insurance suffers from adverse selection which results...
This work presents a theory for games with symmetric externali-ties, where the externalities by any one player imposed on another is same as the vice versa. The theory connects a social optimum outcome with its eigen-equilibrium, a Nash equilibrium of a game that is attained by transforming a social optimum. An implication of the theory is that social optimum could be implemented in a way with ...
This paper analyzes equilibrium and welfare for a tractable class of economies (games) that have externalities, strategic complementarity or substitutability, and heterogeneous information. First, we characterize the equilibrium use of information: complementarity heightens the sensitivity of equilibrium actions to public information, raising aggregate volatility, whereas substitutability heigh...
A social network in which individuals seek to be early adopters of a popular trend has as its equilibrium structure a (unique) leader and hierarchy of followers. The analysis generating this equilibrium fails to offer a mechanism for the equilibrium to emerge from an initially unstructured social environment. A dynamic model with evolving social links is employed to test for and understand the ...
This paper describes the relationship between two different binary choice social interaction models. The Brock and Durlauf (2001) model is essentially a static Nash equilibrium model with random utility preferences. In the Blume (forthcoming) model is a population game model similar to Blume (1993), Kandori, Mailath, and Rob (1993) and Young (1993). We show that the equilibria of the Brock-Durl...
This chapter addresses the relationship between sociology and NonEquilibrium Social Science (NESS). Sociology is a multiparadigmatic discipline with significant disagreement regarding its goals and status as a scientific discipline. Different theories and methods coexist temporally and geographically. However, it has always aimed at identifying the main factors that explain the temporal stabili...
We study techniques to incentivize self-interested agents to form socially desirable solutions in scenarios where they benefit from mutual coordination. Towards this end, we consider coordination games where agents have different intrinsic preferences but they stand to gain if others choose the same strategy as them. For non-trivial versions of our game, stable solutions like Nash Equilibrium m...

abstract deviation or in other words committing a crime is literally a social problem. this research that was conducted in 1389 and 1390 has tried to investigate the causes of crimes committed by young male inmates qazvin central prison and effective variables on their tendency to deviation. accordingly after collecting theoretical framework and offering theoretical model including both hirsch...
