The direct and indirect effects of geographic diversification on an MNC’s stock market
April 7, 2017
3-4 p.m., Stephens Hall, Room 310
Presented by Chaodong Han
Using a mediating model and firm-level data collected from CompuStat database during
2000-2011, we examine the direct and indirect effects of geographic diversification
on an MNC’s stock market (Tobin’s q) and financial performances (ROA), with inventory
level as a mediator. Additionally, our examination is implemented separately under
two heterogeneous economic situations: financial crisis vs. without financial crisis.
Our results show that geographic diversification enhances an MNC’s stock market performance,
while deteriorating its financial performance in the presence of a financial crisis.
In contrast, geographic diversification has little direct impact on an MNC’s stock
market and financial performances during periods without financial crisis. The indirect
effects of geographic diversification are mediated by changes in inventory levels.
Humanitarian Logistics and Supply Chain Management Research: A Bibliometric study
on central themes and trends
Nov. 4, 2016
3 p.m., Stephens Hall, Room 310
Presented by Tobin Porterfield
Humanitarian logistics and supply chain management research is a relatively new area
with much of the published journal articles having been generated in the past fifteen
years. The area of research has been evolving with motivation from major natural disasters
and increased pressure from donors to improve the efficiency of humanitarian operations.
In order to organize and understand the existing literature, a bibliometric analysis
is conducted applying quantitative tools for the analysis of trends, citations, and
co-citations. Preliminary results suggest an increasing volume but a concentration
of journals and a fragmentations of contributing authors. Co-citation relationships
are being evaluated using a dense network subgrouping algorithm which results in clusters
or communities of interest around topics within the area.
Information Cues and Online Product Sales Performance
April 1, 2016
Presented by Xiaolin Li
The study empirically explores the impact of different information cues on sales performance
of online products. The analysis of a big dataset about the reviews and sales of products
on Amazon.com reveals diverse effects of different information cues on the sales performance
of products. The findings have significant implications for both business practice and research.
U.S. Department of Energy Office of Fossil Energy Quadrennial Technology Review 2015
Oct. 2, 2015
Presented by Rana Rassipour
Fossil fuel resources account for 82% of total U.S. primary energy use because they
are abundant, have a relatively low cost of production, and have a high energy density—enabling
easy transport and storage. The infrastructure built over decades to supply fossil
fuels is the world’s largest enterprise with the largest market capitalization. Of
fossil fuels, oil and natural gas make up 63% of energy usage.[i] Across the energy
economy, the source and mix of fuels used across these sectors is changing, particularly
the rapid increase in natural gas production from unconventional resources for electricity
generation and the rapid increase in domestic production of shale oil.
While oil and gas fuels are essential for the United States’ and the global economy,
they also pose economic, security and environment challenges. Oil and gas have advantages
and disadvantages with respect to these challenges. Since these needs are vital to
the national interest, it is essential to demonstrate improvement across all three
dimensions and maintain a robust set of options for rapidly changing conditions.
The primary research needs for the oil and gas are related to resource extraction.
Current technology is reviewed and key research and development (R&D) opportunities
are identified that could help resolve sector challenges with specific technology
assessments in these major areas: unconventional oil and gas, Co2- enhanced oil recovery
(EOR), offshore oil spill prevention, gas hydrates and transportation infrastructure.
Coordination in Humanitarian Supply Chain Management
April 10, 2015
Presented by Chaodong Han
Grounded in systems thinking and coordination theory, this study intends to build
a typological framework of coordination in humanitarian supply chain management, disaster
relief operations in particular. Following established case study methodologies, we
collect archival data on five relief operations - 2010 Haiti Earthquake, 2010 Chile
Earthquake, 2008 China Earthquake, 2005 U.S. Katrina and 2004 South Asia Tsunami and
conduct a comparative case study. Through identifying coordination problems and assessing
coordination mechanisms used accordingly, we build a typological coordination framework
for disaster relief operations.
Does donation facilitate electricity saving?
Nov. 7, 2014
Presented by Hiroko Okajima
Smart meters present new opportunities that have not been possible with traditional
meters. They can facilitate improving energy efficiency by providing near real-time
usage information. Motivated by the growing interests on electricity saving programs
using smart meters, we conduct laboratory experiments to explore how people react
to individual and group monetary/nonmonetary incentives to save electricity. Specifically,
we examine the effects of donation on electricity saving.
Assessing and Standardizing Military Unit Readiness
April 4, 2014
Presented by Natalie Scala
One of the most difficult measurements to obtain with some level of accuracy is military
readiness to provide defense. The U.S. military has a requirement for units to report
an overall readiness rating based on a multitude of factors. This research examines
the current readiness reporting method and proposes a new benchmarking system based
on desirability functions from quality theory, assessing readiness on quantitative
and qualitative scales with aggregation so that a holistic approach is taken.
Modeling Agent Auctions in the Two Dimensions of Price and Quantity
Nov. 1, 2013
Presented by Barin Nag
In agent-based multi-period auction trading, inventory costs and trading penalties
affect two dimensional decisions of price and quantity to trade or carry over. Cooperation
and collaboration between buyer agents and seller agents respectively facilitate trades.
Heuristic algorithms implementing a mathematical model demonstrate the effectiveness
in a simulation experiment.
