In this paper, we study the Nash implementation in an allocation problem with single-dipped preferences. We show that, with at least three agents, Maskin monotonicity is necessary and sufficient for implementation. We examine the implementability of various social choice correspondences (SCCs)...

In this paper we explore the problem of Nash implementation providing two new properties called I-monotonicity and I-weak no-veto power. These properties form together with unanimity a new sufficient condition for a social choice correspondence to be implementable in Nash equilibria with at...

In exchange economies with single-peaked preferences, we find that: (1) several solutions satisfy Theorem 1 of Doghmi and Ziad [Doghmi, A., Ziad, A., 2008-this issue. Reexamination of Maskin's theorem on Nash implementability. Economics Letters.], (2) strict monotonicity is equivalent to Maskin...

We reexamine Maskin's Theorem by proposing slight modifications on Maskin's conditions of monotonicity and no veto power. We show that any social choice correspondence (SCC) that satisfies strict monotonicity, strict no veto power and unanimity can be implemented in Nash equilibria.

We analyze the impact of institutional and cultural factors on the supply side of open source software (OSS). OSS is a privately provided public good: it is marked by free access to the software and its source code, and is developed in a public, collaborative manner by thousands of volunteers as...

This paper analyzes the development of the German knowledge base measured by co-classifications of patents by German inventors and relate this technological development to changes in the structure of the underlying inventor networks. The central hypothesis states that technologies that become...
