Assortment optimization is a fundamental problem in revenue management, in which the objective usually is to select a subset of products to offer to customers in order to maximize expected revenue or profit. However, business practices often involve multiple, and potentially conflicting goals....

The main goal of this was to examine the impact of the SNAP program on the allocation of food and nonfood spending expenditures across six subgroups: food, utilities, apparel, transportation, medical care, and other nonfood spending. The empirical analysis is conducted using a consumer demand...

This paper investigated a 12-slot/11-pole flux switching permanent magnet (FSPM) machine used for electric vehicles (EVs). Five novel rotor teeth shapes are proposed and researched to reduce the cogging torque and torque ripple of the FSPM machine. These rotor teeth shapes are notched teeth,...

This paper presents a novel five-phase permanent magnet synchronous motor (PMSM), which contains dual rotors and a single stator, equivalent to two five-phase motors working together. Thus, this kind of motor has the potential of good fault tolerant capability and high torque density, which...

In this paper we show that sorting different ability contestants in piece rate tournaments into more homogeneous groups alters incentives for agents to exert effort. In particular we show that for a given mean of the tournament group's ability parameters, larger variance (more heterogeneous...

In this paper we propose a game-theoretic model of a rank-order tournament with private information and characterize its equilibrium solution. The model captures many important features of the production contracts once observed in the poultry industry. We use the contract settlement data from a...

This study analyzes the factors that determine the demand for milk products and the consumer benefits from organic milk introduction. Estimating a structural model, the welfare effect is decomposed into two parts: the effect of having an additional product and the effect from the price changes...

Motivated by several interesting features of the highway mowing auction data from Texas Department of Transportation (TDoT), we propose a two-stage procurement auction model with endogenous entry and uncertain number of actual bidders. Our entry and bidding models pro vide several interesting...

The competing risks technique is applied to the analysis of times to execution and cancellation of limit orders submitted on an electronic trading platform. Time-to-execution is found to be more sensitive to the limit price variation than time-to-cancellation, even though it is less sensitive to...

In this paper we study the productivity-survival link in the U.S. poultry processing industry using the longitudinal data constructed from five Censuses of Manufactures between 1987 and 2007. First, we study the effects of physical productivity and demand-specific factors on plant survival and...
