Between Search and Walras
We present a model in which unemployed workers simultaneously sample n potential employers. By varying n, we nest search and Walrasian-type models of the labor market. We show that low values of n yield typical search equilibria: the wages are dispersed below the marginal productivity of labor. Interestingly, as n exceeds a relatively small threshold, the Walrasian-type equilibrium emerges with...
متن کاملBihomogeneity and Menger Manifolds
It is shown that for every triple of integers (α, β, γ) such that α ≥ 1, β ≥ 1, and γ ≥ 2, there is a homogeneous, non-bihomogeneous continuum whose every point has a neighborhood homeomorphic the Cartesian product of Menger compacta μ ×μ × μ . In particular, there is a homogeneous, non-bihomogeneous, Peano continuum of covering dimension four.
متن کاملOn the modernity of Walras
This text is to appear in a volume produced at the occasion of the 100th anniversary of Léon Walras death. The first part (introduction) answers one initial demand (to the solicited authors), i.e the evaluation of Walras influence on their own research and more generally on contemporary research. The second part “Between the Capitol Hill and the Tarpeian Rock ? ” goes further into the discussio...
متن کاملSome Remarks on Almost Menger Spaces and Weakly Menger Spaces
{V : V ∈ Vn} = X . Clearly, every Menger space is almost Menger and every almost Menger space is weakly Menger, but the converses do not hold (see Examples 2.1 and 2.2). On the study of weakly Menger spaces, almost Menger spaces and Menger spaces, the readers can see the references [2, 3, 4, 5, 6]. Here we investigate the relationships among almost Menger spaces, weakly Menger spaces and Menger...
متن کاملMenger remainders of topological groups
In this paper we discuss what kind of constrains combinatorial covering properties of Menger, Scheepers, and Hurewicz impose on remainders of topological groups. For instance, we show that such a remainder is Hurewicz if and only it is σ-compact. Also, the existence of a Scheepers non-σ-compact remainder of a topological group follows from CH and yields a P -point, and hence is independent of Z...
