Equilibrium Modeling And Policy Analysis Of A Biofuel Supply Chain With A Hydroelectric Reservoir, Jinwoo Bae Aug 2019

Equilibrium Modeling And Policy Analysis Of A Biofuel Supply Chain With A Hydroelectric Reservoir, Jinwoo Bae

Theses and Dissertations

This research proposesd a game theoretic model of a biofuel supply chain (BSC) where a utility company supplies reservoir water to two farmers, located in downstream and upstream of a hydropower dam. The decision-making process of the model is formulated as a three-stage Stackelberg game. We analyze the equilibrium of the decentralized systems and the effect of the government subsidy on energy crop (switchgrass) production for cellulosic biofuel industries, with two forms of subsidy: (1) discriminated subsidies and (2) equalized subsidies.

The results show that both forms of subsidy improve social welfare in the BSC unless the amount of subsidy ...

Economics Of Non-Neutrality In The Internet, Mohammad Hassan Lotfi Jan 2017

Economics Of Non-Neutrality In The Internet, Mohammad Hassan Lotfi

Publicly Accessible Penn Dissertations

Net-neutrality on the Internet is the set of policies that prevents a paid or unpaid discrimination by Internet Service Providers (ISPs) among different types of transmitted data. The recent moves to change the net neutrality rules and the growing demand for data have driven the ISPs to provide differential treatment of traffic to generate additional revenue streams from Content Providers (CPs). In this thesis, we consider economic frameworks to investigate different questions about the departure toward a non-neutral regime and its possible consequences. In particular, we i) assess whether different entities of the market have the incentive to adopt a ...


The Long Term Effects Of An Aging Fleet On Operational Availability And Cost: Evidence From The Us Coast Guard, Christopher W. Lavin, Robert M. Mcnab, Ryan S. Sullivan Jan 2017

The Long Term Effects Of An Aging Fleet On Operational Availability And Cost: Evidence From The Us Coast Guard, Christopher W. Lavin, Robert M. Mcnab, Ryan S. Sullivan

Economics Faculty Publications

This paper empirically examines whether the aging of a fleet affects operational availability and operating cost using a unique data-set on the 117 47-foot Motor Lifeboats (MLBs) of the United States Coast Guard (USCG). Procured from 1997 to 2003, the 47-foot MLB is the standard lifeboat of the USCG and all 117 MLBs remain in service. The aging of the MLB fleet has resulted in higher annual operating costs and lower operational availability, although the nature of this relationship remains unclear. Our estimation strategy utilizes an error components estimator to examine these issues. We employ three variants of the dependent ...

Analysis Of Six Monthly Distribution System For Food Grains In The Public Distribution System Of Punjab, India: A Beneficiary's Perspective, Abhay Kumar Grover

Graduate Theses and Dissertations

Public distribution system is a food security program in India providing safety net for the below poverty line citizens of the country. Its objective is to feed the most vulnerable population by providing subsidized food grains and other essential commodities on a monthly basis through its integrated network of supply chain. But the system is affected by various inefficiencies and malpractices. To improve the efficacy of the system, the state of Punjab introduced the new atta-daal (wheat pulses) scheme. One of the features of the scheme was to distribute grains to the beneficiaries on a six monthly basis (semi-annually) instead ...


Strategic Inventories In A Supply Chain With Vertical Control And Downstream Cournot Competition, Vijayendra Viswanathan May 2016

Strategic Inventories In A Supply Chain With Vertical Control And Downstream Cournot Competition, Vijayendra Viswanathan

Theses and Dissertations

Strategic Inventory (SI) has been an area of increased interest in theoretical supply chain literature recently. Most of the work so far however, has only considered a supply chain without downstream competition between retailers. Competition is ubiquitous in most market situations, hence, interactions between SI and retailer competition merits study as a first step in bringing the conversations and insights from this stream of literature to the real world.

We present here a two-period and a three-period model of one manufacturer supplying an identical product to two retailers who form a Cournot duopoly. We also study a Commitment contract, where ...


The Bakken Goes Boom: Oil And The Changing Geographies Of Western North Dakota, William Caraher, Kyle Conway Feb 2016

The Bakken Goes Boom: Oil And The Changing Geographies Of Western North Dakota, William Caraher, Kyle Conway

Digital Press Books

In 2008, the Bakken went boom. Thanks to advances in hydraulic fracturing, oil production in western North Dakota exploded. As the price of oil went up, so did the oil rigs. People came from all over the country (and the world) in search of work, and cities and towns struggled to keep up. This book is about the challenges they faced. It is about the human dimensions of the boom, as told by artists, poets, journalists, and scholars. It captures the boom at its peak, before the price of oil fell and the boom went bust.

This is the only ...


Evolution Of The Secondary Spectrum Market, Arnob Ghosh Jan 2016

Evolution Of The Secondary Spectrum Market, Arnob Ghosh

Publicly Accessible Penn Dissertations

The secondary spectrum market where primaries (license holders) lease the secondaries (unlicensed users) in lieu of the financial remuneration can eliminate the inefficiencies of the "static" spectrum allocation policy. We redress some of the challenges that have inhibited the wide scale deployment of the secondary spectrum market.

We first consider a secondary spectrum market where the primaries quote their prices for their available channels at a single location. The transmission rates offered by the channels of primaries evolve randomly because of the fading and noise. The secondaries decide to buy among the channels based on the transmission rate and the ...


The Economic Costs Of Natural Disasters, Terrorist Attacks, And Other Calamities: An Analysis Of Economic Models That Quantify The Losses Caused By Disruptions, Amro Al Kazimi, Cameron A. Mackenzie Jan 2016

The Economic Costs Of Natural Disasters, Terrorist Attacks, And Other Calamities: An Analysis Of Economic Models That Quantify The Losses Caused By Disruptions, Amro Al Kazimi, Cameron A. Mackenzie

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Over the past decade, numerous studies have estimated the economic impacts of a variety of disruptions. Most of these studies are based on macroeconomic models that quantify the direct and indirect economic losses from a disruption. Direct economic losses occur due to damaged facilities or when consumers change their purchasing behavior because of the disruption. Indirect economic losses occur when directly impacted businesses consequently reduce their orders to their suppliers. Indirect economic losses are often larger than direct economic losses. This paper compiles the results from these economic models in order to compare the costs of different disruptions and help ...


Cloud Computing, Contractibility, And Network Architecture, Christopher S. Yoo Apr 2015

Cloud Computing, Contractibility, And Network Architecture, Christopher S. Yoo

Faculty Scholarship at Penn Law

The emergence of the cloud is heightening the demands on the network in terms of bandwidth, ubiquity, reliability, latency, and route control. Unfortunately, the current architecture was not designed to offer full support for all of these services or to permit money to flow through it. Instead of modifying or adding specific services, the architecture could redesigned to make Internet services contractible by making the relevant information associated with these services both observable and verifiable. Indeed, several on-going research programs are exploring such strategies, including the NSF’s NEBULA, eXpressive Internet Architecture (XIA), ChoiceNet, and the IEEE’s Intercloud projects.


Strategic Flexibility, Kihyung Kim Oct 2014

Strategic Flexibility, Kihyung Kim

Open Access Dissertations

A flexible system is defined as one that can change the entity's stance, capability or status reacting to a change of the entity's environment. Flexibility has gathered the attention of academic researchers and industry practitioners as an efficient approach to cope with today's volatile environment. As the environments become more unpredictable and volatile, it is imperative for a flexible system to respond quickly to a change in its circumstance. How much flexibility is embedded into the system also has a critical impact on the long-term effectiveness of the flexible system. Moreover, this research focuses on the strategic ...


Interpreting, Stephanie Jo Kent May 2014

Interpreting, Stephanie Jo Kent

Doctoral Dissertations

What do community interpreting for the Deaf in western societies, conference interpreting for the European Parliament, and language brokering in international management have in common? Academic research and professional training have historically emphasized the linguistic and cognitive challenges of interpreting, neglecting or ignoring the social aspects that structure communication. All forms of interpreting are inherently social; they involve relationships among at least three people and two languages. The contexts explored here, American Sign Language/English interpreting and spoken language interpreting within the European Parliament, show that simultaneous interpreting involves attitudes, norms and values about intercultural communication that overemphasize information and ...

Economic Decision Making Of Renewable Power Producers Under Uncertainty, Chenlu Lou Jan 2014

Economic Decision Making Of Renewable Power Producers Under Uncertainty, Chenlu Lou

Graduate Theses and Dissertations

The recent booming development of renewable power generation and government subsidies are constantly under scrutiny and various opinions exist regarding whether subsidies should be continued or not. Motivated by the controversies and debates, this dissertation attempted to address the investment decision making problem under uncertainties in the renewable power industry from the perspective of an individual power producer.

Given that independent power producers still dominate the renewable power production and that majority of their output are sold through long-term power purchase agreements, this study focused on two types of uncertainties that could represent most of their kinds: the operations & maintenance ...


Securing Access To Lower-Cost Talent Globally: The Dynamics Of Active Embedding And Field Structuration, Stephan Manning, Joerg Sydow, Arnold Windeler Mar 2013

Securing Access To Lower-Cost Talent Globally: The Dynamics Of Active Embedding And Field Structuration, Stephan Manning, Joerg Sydow, Arnold Windeler

Stephan Manning

This article examines how multinational corporations (MNCs) shape institutional conditions in emerging economies to secure access to high-skilled, yet lower-cost science and engineering talent. Based on two in-depth case studies of engineering offshoring projects of German automotive suppliers in Romania and China we analyze how MNCs engage in ‘active embedding’ by aligning local institutional conditions with global offshoring strategies and operational needs. MNCs thereby contribute to the structuration of field relations and practices of sourcing knowledge-intensive work from globally dispersed locations.Our findings stress the importance of institutional processes across geographic boundaries that regulate and get shaped by MNC activities.


A Mechanism Design Approach To Bandwidth Allocation In Tactical Data Networks, Ankur Mour Jan 2013

A Mechanism Design Approach To Bandwidth Allocation In Tactical Data Networks, Ankur Mour

Open Access Theses

The defense sector is undergoing a phase of rapid technological advancement, in the pursuit of its goal of information superiority. This goal depends on a large network of complex interconnected systems - sensors, weapons, soldiers - linked through a maze of heterogeneous networks. The sheer scale and size of these networks prompt behaviors that go beyond conglomerations of systems or `system-of-systems'. The lack of a central locus and disjointed, competing interests among large clusters of systems makes this characteristic of an Ultra Large Scale (ULS) system. These traits of ULS systems challenge and undermine the fundamental assumptions of today's software and ...

Measuring Changes In International Production From A Disruption: Case Study Of The Japanese Earthquake And Tsunami, Cameron A. Mackenzie, Joost R. Santos, Kash Barker Jan 2012

Measuring Changes In International Production From A Disruption: Case Study Of The Japanese Earthquake And Tsunami, Cameron A. Mackenzie, Joost R. Santos, Kash Barker

Cameron A. MacKenzie

The earthquake and tsunami that struck Japan on March 11, 2011 caused a tremendous loss of life and property. The disaster also disrupted global supply chains, which was blamed for anemic growth in the global economy. A multiregional input-output model can quantify the international impacts on production due to changes in demand from companies reducing their orders because of a disruption. Using the input-output model to conceptualize a supply chain, we present a unique method for calculating indirect production losses caused by disabled production facilities. Methods for calculating the possible transfer of demand to industries in other countries are also ...

Electricity System Expansion Studies To Consider Uncertainties And Interactions In Restructured Markets, Shan Jin Jan 2012

Electricity System Expansion Studies To Consider Uncertainties And Interactions In Restructured Markets, Shan Jin

Graduate Theses and Dissertations

This dissertation concerns power system expansion planning under different market mechanisms. The thesis follows a three paper format, in which each paper emphasizes a different perspective. The first paper investigates the impact of market uncertainties on a long term centralized generation expansion planning problem. The problem is modeled as a two-stage stochastic program with uncertain fuel prices and demands, which are represented as probabilistic scenario paths in a multi-period tree. Two measurements, expected cost (EC) and Conditional Value-at-Risk (CVaR), are used to minimize, respectively, the total expected cost among scenarios and the risk of incurring high costs in unfavorable scenarios ...


Cap-And-Trade Modeling And Analysis For Electric Power Generation Systems, Patricio Rocha Jan 2011

Cap-And-Trade Modeling And Analysis For Electric Power Generation Systems, Patricio Rocha

Graduate Theses and Dissertations

Cap-and-trade is the most discussed CO2 emissions control scheme in the U.S. It is a market-based mechanism that has been used previously to successfully reduce the levels of SO2 and NOx emitted by power generators. Since electricity generators are responsible for about 40% of the CO2 emissions in the U.S., the implementation of CO2 cap-and-trade will have a significant impact on electric power generation systems. In particular, cap-and-trade will influence the investment decisions made by power generators. These decisions in turn, will affect electricity prices and demand. If the allowances (or emission permits) created by a cap-and-trade program ...

Economic Efficiencies Of The Energy Flows From The Primary Resource Suppliers To The Electric Load Centers , Ana Margarida Quelhas Alves De Freitas Jan 2006

Economic Efficiencies Of The Energy Flows From The Primary Resource Suppliers To The Electric Load Centers , Ana Margarida Quelhas Alves De Freitas

Retrospective Theses and Dissertations

The economic efficiency of the electric energy system depends not only on the performance of the electric generation and transmission subsystems, but also on the ability to produce and transport the various forms of primary energy, particularly coal and natural gas. However, electric power systems have traditionally been developed and operated without a conscious awareness of the energy system-wide implications, namely the consideration of the integrated dynamics with the fuel markets and infrastructures. This has been partly due to the difficulty of formulating models capable of analyzing the large-scale, complex, time-dependent, and highly interconnected behavior of the integrated energy system ...

Generation Planning For Electric Power Utilities Under Market Uncertainties: A Real Options Approach , Chung-Hsiao Wang Jan 2001

Generation Planning For Electric Power Utilities Under Market Uncertainties: A Real Options Approach , Chung-Hsiao Wang

Retrospective Theses and Dissertations

The generation business in the U.S. is currently undergoing a transition from a regulated monopoly toward an uncertain, competitive market. Under the competitive market, the price of electric power as well as the corresponding revenue may be much less certain than before. These market uncertainties have increased the significance of two critical factors in generation planning. These factors are financial risks and managerial flexibilities.;In order to quantitatively and objectively address these two factors in generation planning, in this dissertation, we design and analyze a series of mathematical models based on the real options approach for generation planning. Hence ...
