Recent experiments have established that, at least for van der Waals glass formers, volume fluctuations contribute significantly to the slowing down of the dynamics near T(g). Accordingly, we use the Cohen-Grest (CG) free-volume model to analyze dielectric relaxation data for six van der Waals liquids. The CG equation accurately describes the structural relaxation times over broader ranges of t...

We characterize the revenue maximizing mechanism in a two-period model. A risk neutral seller owns one unit of a durable good and faces a risk neutral buyer whose valuation is private information. The seller has all the bargaining power; she designs an institution to sell the object at t=0 but she cannot commit not to change the institution at t=1 if trade does not occur at t=0. The seller’s ob...

We revisit the known problem whether each compact topology is contained in a maximal compact topology and collect some partial answers to this question. For instance we show that each compact topology is contained in a compact topology in which convergent sequences have unique limits. We also answer a question of D.E. Cameron by showing that each sequentially compact topology is contained in a ...

In this paper, we examine the questions of which coalition structure is formed and how payoãis distributed among players in cooperative games with externalities. We introduce a sequential stability concept called a sequentially stable payoãconåguration in a game with a coalition structure by extending the concept of the equilibrium binding agreements by Ray and Vohra (1997). Ray and Vohra captu...
