A Conceptual Model To Evaluate Decisions For Service Profitability, Eng Lieh Ouh, Stan Jarzabek Mar 2015

A Conceptual Model To Evaluate Decisions For Service Profitability, Eng Lieh Ouh, Stan Jarzabek

Research Collection School Of Computing and Information Systems

Service profitability depends on the cost of engineering a service for a given base of tenants, on service provisioning cost, and on the revenue gained from selling the service to that tenant base. The tenant base depends on the range of service variability, i.e., on Service Provider's ability to vary service requirements to meet tenant expectations. These various factors that have to do with service profitability form a complex web of information that makes it difficult to analyze and see the exact impact of decisions regarding the choice of service architecture or the use of service adaptation techniques. To make …


A Regime Switching Model For The Term Structure Of Credit Risk Spreads, Seungmook Choi, Michael D. Marcozzi Feb 2015

A Regime Switching Model For The Term Structure Of Credit Risk Spreads, Seungmook Choi, Michael D. Marcozzi

Mathematical Sciences Faculty Research

We consider a rating-based model for the term structure of credit risk spreads wherein the credit worthiness of the issuer is represented as a finite-state continuous time Markov process. This approach entails a progressive drift in creditquality towards default. A model of the economy is presented featuring stochastic transition probabilities; credit instruments are valued via an ultraparabolic Hamilton-Jacobi system of equations discretized utilizing the method-of-lines finite difference method. Computations for a callable bond are presented demonstrating the efficiency of the method.

Dept. of Marketing & International Business Conference Material

In the contemporary landscape, human interaction is characterized by the pervasive mediation of intelligent agents. Owing to advances in computer science and engineering, phenomena once limited to fixed locations are metamorphosing from extraneous entities to implicit components of the everyday. Computing power has simultaneously enhanced and miniaturized to the extent that contemporary consumer devices demonstrate power equivalent to or greater than that of personal computers of recent memory. At the same time, network connectivity has proliferated to ubiquitous levels, reflected in the fact that the amount of inanimate objects connected to the Internet has recently surpassed the human population of …


A Simulation-Based Approach To Solve A Specific Type Of Chance Constrained Optimization, Lijian Chan Feb 2015

A Simulation-Based Approach To Solve A Specific Type Of Chance Constrained Optimization, Lijian Chan

MIS/OM/DS Faculty Publications

We solve the chance constrained optimization with convex feasible set through approximating the chance constraint by another convex smooth function. The approximation is based on the numerical properties of the Bernstein polynomial that is capable of effectively controlling the approximation error for both function value and gradient. Thus, we adopt a first-order algorithm to reach a satisfactory solution which is expected to be optimal. When the explicit expression of joint distribution is not available, we then use Monte Carlo approach to numerically evaluate the chance constraint to obtain an optimal solution by probability. Numerical results for known problem instances are …

It-Enabled Coordination In Electronic Markets: An Experimental Investigation Of The Effects Of Social Communication On Group Buyers, Alexander Pelaez

Dissertations, Theses, and Capstone Projects

Coordination, and the mechanisms by which coordination occurs, represents a significant area of study for economic research, and information technology. Technology enhances communication in both speed and quantity of information and when aligned with appropriate tasks can improve decision-making and task performance. Examining the effect of technology based coordination mechanisms on market platforms provides insight into outcomes as represented by buyer surplus and task completion as well as behaviors, such as network structure and emotional attitudes in economic experiments. Drawing on theory from economics and information systems, larger buyer groups should be able to obtain better prices and extract higher …


Linking Sustainability To Quality Management And Firm Performance, Rajat Mishra, Randy Napier Jan 2015

Linking Sustainability To Quality Management And Firm Performance, Rajat Mishra, Randy Napier

Faculty Publications

Environmental management practices have evolved significantly over the past two decades. During that time, sustainable operations management practices have purportedly made positive contributions to overall firm performance. This paper develops two conceptual frameworks regarding the relationships among specific elements of environmental management, quality management, and firm performance. We suggest that innovation in quality management mediates the relationship between design for environment and firm performance, and that statistical process control techniques moderate the relationship between environmental management systems and firm performance. We identify future research possibilities, based on these frameworks, to inform scholarly research and practice in environmental management and quality …

Derivatives Pricing With Accelerated Trinomial Trees, Conall O'Sullivan, Stephen O'Sullivan Jan 2015

Derivatives Pricing With Accelerated Trinomial Trees, Conall O'Sullivan, Stephen O'Sullivan

Articles

Accelerated Trinomial Trees (ATTs) are a derivatives pricing lattice method that circumvent the restrictive time step condition inherent in standard trinomial trees and explicit finite difference methods (FDMs) in which the time step must scale with the square of the spatial step. ATTs consist of L uniform supersteps each of which contains an inner lattice/trinomial tree with N non-uniform subtime steps. Similarly to implicit FDMs, the size of the superstep in ATTs, a function of N, are constrained primarily by accuracy demands. ATTs can price options up to N times faster than standard trinomial trees (explicit FDMs). ATTs can be …

Decoy Effect And Student Preference With Regard To Usb Flash Drives, Jeff Arapoc Jan 2015

Decoy Effect And Student Preference With Regard To Usb Flash Drives, Jeff Arapoc

Journal of Economics, Management and Agricultural Development

Standard economic theory assumes that individuals make decisions that are consistent across different choice situations. Behavioral economics challenges the standard economic theory account of individual behavior. This budding field suggests that consumer preference for one option over another changes as a result of adding another option. This study aims to determine the effect of a decoy option on consumer preference for USB flash drives. A quasi-experiment was conducted among 100 UPLB students wherein each respondent was initially asked to choose between two kinds of flash drive. The researcher then adds a decoy option to test if the respondent will change …

Building Disaster Resilience To Address Household Food Security: The Case Of Sta. Rosa-Silang Subwatershed, Roberto F. Ranola Jr., Mi Cuesta, Bam Zaraf

Journal of Economics, Management and Agricultural Development

The Laguna Lake Region is one of the places in the Philippines that are most vulnerable to natural disasters because of their location and ecological condition. Among the natural calamities that regularly hit the country, one of the most frequent and disastrous is flooding. The most affected are the poor who are faced with the double risk of being food insecure and living in conditions that are very vulnerable to natural hazards. The most negative and long-term effect of flooding is reduction in food security because flooding erodes the asset base of households that in turn results in the adoption …
