The use of social networks in the workplace has been documented by many authors, although the reasons for their widespread prevalence are less well known. In this paper we present evidence based on a lab experiment that suggests quite strongly that social networks are used by employers to reduce...

We study ex-post hiring risks in low income countries with limited legal and regulatory frameworks. In our theory of employee referral, the new re- cruit internalises the rewards and punishments of the in-house referee meted out by the hiring firm. This social mechanism makes it cheaper for the...

The use of social networks in the workplace has been documented by many authors, although the reasons for their widespread prevalence are less well known. In this paper we present evidence based on a combined eld-laboratory experiment that social networks are used by employers to reduce worker...

This paper studies a strategic aspect of profit-sharing in an oligopolistic industry with a monopoly union. Whenever a uniform profit share exists in the industry, we show that a union that values the per worker remuneration positively, may have incentives to reduce industry employment,...

This chapter gives a flavour of recent theoretical work on coalition formation and political parties. I survey recent work on both pre-election coalition formation and post election coalition (or government) formation. A number of alternative rationales for the formation of parties are compared...

This paper studies the dominance-solvability (by iterated deletion of weakly dominated strategies) of general scoring rule voting games. The scoring rules we study include Plurality rule, Approval voting, Negative Plurality Rule, Borda rule and Relative Utilitarianism. We provide a...

This paper compares default incentives in competitive sovereign debt markets when leaders can be either democratically elected or dictators. When leaders can be replaced as in democracies, the incentives for repayment are mainly the ego rents from office and the possibility of getting a corrupt...

In a classic model of tax competition, we show that the level of public good provision and taxation in a Nash equilibrium can be efficient or inefficient with either too much, or too little public good provision. The key is whether there exists a unilateral incentive to deviate from the...

Many firms have more than one blockholder, but finance theory suggests that one blockholder should be sufficient to bestow all benefits on a firm that arise from concentrated ownership. This paper identifies a reason why more blockholders may arise endogenously. We consider a setting where...

Both complete and incomplete game Theoretic Models of Voter Turnout (Palfrey and Rosenthal, 1983,1985) have the problem of multiple equilibria, some of which seem unreasonable. How can the counter intuitive high turnout equilibria be explained? Palfrey and Rosenthal (1985) suggest that the main...
