Ranking friends
Kets, Willemien; Feinberg, Yossi - 2012
We investigate the scope for cooperation within a community engaged in repeated reciprocal interactions. Players seek the help of others and approach them sequentially according to some fixed order, that is, a ranking profile. We study the ranking profiles that are most effective in sustaining...

Correlation of types in Bayesian games
De Castro, Luciano - 2012
Despite their importance, games with incomplete information and dependent types are poorly understood; only special cases have been considered and a general approach is not yet available. In this paper, we propose a new condition (named richness) for correlation of types in (asymmetric) Bayesian...

Jump bidding and budget constraints in all-pay auctions and wars of attrition
Dekel, Eddie; Jackson, Matthew O.; Wolinsky, Asher - 2007
We study all-pay auctions (or wars of attrition), where the highest bidder wins an object, but all bidders pay their bids. We consider such auctions when two bidders alternate in raising their bids and where all aspects of the auction are common knowledge including bidders.valuations. We analyze...

Affiliation, equilibrium existence and revenue ranking of auctions
De Castro, Luciano I. - 2010
Affiliation has been a prominent assumption in the study of economic models with statistical dependence. Despite its large number of applications, especially in auction theory, affiliation has limitations that are important to be aware of. This paper shows that affiliation is a restrictive...

Existence, Uniqueness, and Determinacy of Equilibria in Complete Security Markets with Infinite Dimensional Martingale Generator
Kusuda, Koji - 2002
There is a strong evidence that most of financial variables are better described by a combination of difusion and jump processes. Considering such evidence, researchers have studied security market models with jumps, in particular, in the context of option pricing. In most of their models, jump...

On the smoothness of value functions
Strulovici, Bruno; Szydlowski, Martin - 2012
We prove that under standard Lipschitz and growth conditions, the value function of all optimal control problems for one-dimensional diffusions is twice differentiable, as long as the control space is compact and the volatility is uniformly bounded below, away from zero. Under similar...

Dufhues, Thomas; Buchenrieder, Gertrud; Fischer, Isabel - 2006
definitions are in use. Recently, social capital in the form of social networks has gained much attention in rural development … theory and empirical research. But social networks or structural components of social capital are a largely missing dimension … review, this work proposes a lean and clear definition of social capital: Social capital is conceived as networks plus …
