Neutralizing Free Choice Items via Maximal Domain Restriction: Farsi -i Indefinites

This paper identifies two types of free choice items (FCIs) in Farsi: yek-i DPs and har -i DPs. Their distribution and interpretation pose a puzzle: yek -i DPs pattern with other existential FCIs, and har -i DPs with other universal FCIs, but both items lose their prototypical FCI behavior when they combine with the accusative marker -ro. The paper shows that the loss of FCI behavior follows from an alternative-based analysis of FCIs (Chierchia 2013) under some assumptions about the semantic effect of -ro. The analysis parallels the explanation for the loss of FCI status of Spanish algunos presented in Alonso-Ovalle & Menéndez-Benito 2011 in that it also relies on the derivation of alternatives that are equivalent to the assertion, hence not excludable.

The maximal domain of meromorphic continuation of a Dirichlet series

Many Dirichlet series are either continuable to the whole complex plane or admit half-planes as their maximal domain of meromorphic continuation. Here we prove that this need not always be true.

On the domain of meromorphy of a multivariate Euler product of Igusa type

This work is an answer to a problem posed by N. Kurokawa and H. Ochiai concerning the natural boundary of meromorphy of a multivariate Euler product of Igusa type. More generally, we introduce and determine the maximal domain of meromorphy of a class of multivariate non-uniform Euler products.

Matching in Networks with Bilateral Contracts

We introduce a model in which firms trade goods via bilateral contracts which specify a buyer, a seller, and the terms of the exchange. This setting subsumes (many-to-many) matching with contracts, as well as supply chain matching. When firms' relationships do not exhibit a supply chain structure, stable allocations need not exist. By contrast, in the presence of supply chain structure, a natural substitutability condition characterizes the maximal domain of firm preferences for which stable allocations are guaranteed to exist. Furthermore, the classical lattice structure, rural hospitals theorem, and one-sided strategy-proofness results all generalize to this setting. (JEL C78, D85, D86, L14)
