This paper develops a simple model in which unemployment arises from a combination of selection and bad luck. During recessions, the proportion of workers who are laid off due to low productivity declines during recessions, diminishing the adverse signaling effect of an unemployment spell. Wage regressions estimated using the Displaced Workers Supplement support this basic prediction of the mod...

This article revisits Akerlof’s (1970) classic adverse-selection market and asks the following question: do greater information asymmetries reduce the gains from trade? Perhaps surprisingly, the answer is no. Better information on the selling side worsens the “buyer’s curse,” thus lowering demand, but may shift supply as well. Whether trade increases or decreases depends on the relative sizes o...

A k-uniform hypergraph is s-almost intersecting if every edge is disjoint from exactly s other edges. Gerbner, Lemons, Palmer, Patkós and Szécsi conjectured that for every k, and s > s0(k), every k-uniform s-almost intersecting hypergraph has at most (s + 1) ( 2k−2 k−1 ) edges. We prove a strengthened version of this conjecture and determine the extremal graphs. We also give some related result...
