Multi-unit questions in institutional interactions: Sequential organizations and communicative functions

Tag Questions in Persian: Investigating the Conversational Functions

This article intends to identify the use and typify the functions of tag questions (TQs) in Persian everyday conversations and dialogic interaction.  The analyses were made based on two data sources:  A documentary film titled Commander in which the participants are engaged in free interactions, and an audio-recorded instrument named CALLFRIEND which consists of Iranian native...

Sequential Auctions with Multi-Unit Demand: Theory, Experiments and Simulations

Approximation Schemes for Sequential Posted Pricing in Multi-unit Auctions

We design algorithms for computing approximately revenue-maximizing sequential postedpricing mechanisms (SPM) in K-unit auctions, in a standard Bayesian model. A seller has K copies of an item to sell, and there are n buyers, each interested in only one copy, who have some value for the item. The seller must post a price for each buyer, the buyers arrive in a sequence enforced by the seller, an...

Strategic interactions in multi-institutional epidemics of antibiotic resistance.

The increasing frequency of antibiotic resistance in hospital-acquired infections is a major public health concern that has both biological and economic causes. Here we develop conceptual mathematical models that couple the economic incentives and population biology of hospital infection control (HIC). We show that the optimal investment by a hospital for HIC changes with the proportion of pati...

An Empirical Model of Multi-unit, Sequential, Ascending-price Auctions∗

We construct a model of participation and bidding at multi-unit, sequential, ascending-price auctions when bidders can potentially have multi-unit demand. We then describe conditions sufficient to characterize a strategic equilibrium of the auction game. Subsequently, we demonstrate that this equilibrium induces an efficient allocation and then propose an algorithm to calculate the expected win...
