Accommodation Or Deterrence In The Face Of Commercial Piracy: The Impact Of Intellectual Property Rights (Ipr) Protections, Yuanzhu Lu, Sougata Poddar
Accommodation Or Deterrence In The Face Of Commercial Piracy: The Impact Of Intellectual Property Rights (Ipr) Protections, Yuanzhu Lu, Sougata Poddar
Economics Faculty Articles and Research
In this paper, we address the issue of illegal copying or counterfeiting of the original product and Intellectual Property Rights (IPR) protections. The original product developer makes costly investment to deter piracy in a given regime of IPR protection. In the presence of a commercial pirate, we find that it is profitable for the original producer to accommodate the pirate when there is weak IPR protection, and deter when the IPR protection is strong. However, in the comparative statics analysis, we find that there is a non-monotonic relationship between the optimal level of deterrence (chosen by the original producer) and …
Impacts Of Social Upbringing On Family Integration In Military Life In Sudan, Professor Issam A.W. Mohamed
Impacts Of Social Upbringing On Family Integration In Military Life In Sudan, Professor Issam A.W. Mohamed
Professor Issam A.W. Mohamed
In a country on the eve of losing one third of its land, 80% of potential natural resources and 75% of external exports value, economic future seems gloomy. Many opinions were given for economic solutions after the Southern Sudan secession. However, that does not support a theoretical framework that those are the only reasons for the expected economic collapse. Our theory here is that such collapse already happened because of economic mismanagement, corruption and hoarding initiated by the calls for empowerment and carried out by the regime's members. Such acts extended to the banks, economic institutions and randomized privatization. The …

Chinese companies of multinationalities currently control the newly born oil industry in the country. Needless to say that the dire needs of the government because of its international isolation and sanctions compelled it to be subjected to bellow standards conditions in all economic and environmental aspects. The government accepted the conditions for the past twelve years. However, the secession of Southern Sudan into new country gives better re-negotiations opportunity to the newly …

Impacts Of Formal Financing On The Development Of The Sudanese Agricultural Sector, Issam A.W. Mohamed Professor
Professor Issam A.W. Mohamed
The agricultural sector of Sudan is faced by many problems. In the irrigated schemes, the government who officially owns most of them there are entrenched managerial problems that brewed for more than six decades. Moreover, the privatization policies of those schemes provoked many outcries and protests. Large schemes like Gezira have collapsed, this year 2011, only 10% of its over one million hectares were cultivated. The rainfed farming is not different with lack of machineries, shortages of available labor and high priced agricultural inputs, it is not expected to fare better than the irrigated schemes. However, even if those problems …
African Economic Blocs And Trade: Case Study Of Comesa And Sudan, Issam A.W. Mohamed Professor
African Economic Blocs And Trade: Case Study Of Comesa And Sudan, Issam A.W. Mohamed Professor
Professor Issam A.W. Mohamed
Comprehensively, Economic Trade Partnerships and Blocs are important to a member country. However, with the continuing global financial distresses it is useful to evaluate them to maximize possible benefit. The question of joining, continue membership with the Comesa is vital to the Sudanese economy that presently stands in a very decisive time. The Common Market for Eastern and Southern Africa is a free trade area with nineteen member states stretching from Libya to Zimbabwe. COMESA formed in December 1994, replacing a Preferential Trade Area which had existed since 1981. Nine of the member states formed a free trade area in …

Testing For Weak Form Market Efficiency In Indian Foreign Exchange Makret, Anoop Sasikumar
Testing For Weak Form Market Efficiency In Indian Foreign Exchange Makret, Anoop Sasikumar
Anoop Sasikumar
This paper attempts to examine the weak form of market efficiency in the Indian foreign exchange market using a family of variance ratio tests. Monthly Nominal Effective Exchange Rate (NEER) data from April 1993-June 2010 were used for the analysis. NEER series was considered for the analysis as it is supposed to capture more information compared to the bilateral exchange rates. Three individual variance ratio tests as well as three joint variance ratio tests were used for the purpose of analysis. After analyzing the results from both individual and joint variance ratio test, it was concluded that Indian foreign exchange …

Global Financial Crisis And Effects On The Agricultural Sector Of Sudan, Issam A.W. Mohamed Professor
Professor Issam A.W. Mohamed
The severe impacts of the global financial crisis had effects on all world. However, in Sudan scientists and researchers were greatly shocked because of the governmental camouflaging on their real effects on the economy. Minister of National Economy and Finance denied the effects on the Sudanese economy. The governor of the Sudan Central bank did the same with emphasis from both that everything are quite and normal and that Sudan can absorb all shocks on its economic performance. Truly, they ave eaten their words in the following months and confessed the partial effects on the Sudanese economy. Moreover, after they …

Impacts Of Sudan Macroeconomic Policy On Agriculture, Issam A.W. Mohamed Professor
Professor Issam A.W. Mohamed
The crisis of Southern Sudan and eminent secession in 9 July 2011 is a nightmare to the Sudanese national economy. The dependence on oil revenue that controlled the country for the past 11 years and negligence of the other real economy's economic sectors, agriculture and industry severely threatens the country. That is not only with diminished returns but with also with economic nightmarish economic catastrophe, famine and internal implosion. Short-sightedness on utilizing the oil money that bubbled the economy atrophied the real economic sectors and disabled it from responding to secession consequences of parting with 75% of revenues from oil …

Wto-Doha Multilateral Trade Negotiations And Agriculture, Professor Issam A.W. Mohamed
Professor Issam A.W. Mohamed
The Doha Development Round or Doha Development Agenda (DDA) is the current trade-negotiation round of the World Trade Organization (WTO), which launched in November 2001. With the start of this round, non-trade concerns (NTCs) were explicitly renowned and integrated into the negotiation process. Generally, multi-functionality proponents attempt to resist agricultural trade liberalization by giving high support to protect their domestic producers. These are net food importing countries, some small countries with highly protected agricultural sector and large trade deficits in some main outputs and unfavourable agro-climatic conditions. The opponents of the multi-functionality argument all claim to recognize the legitimacy of …
Evidence For A Peak Shift In A Humoral Response To Helminths: Age Profiles Of Ige In The Shuar Of Ecuador, The Tsimane Of Bolivia, And The U.S. Nhanes, Aaron D. Blackwell, Michael D.

Evidence For A Peak Shift In A Humoral Response To Helminths: Age Profiles Of Ige In The Shuar Of Ecuador, The Tsimane Of Bolivia, And The U.S. Nhanes, Aaron D. Blackwell, Michael D. Gurven, Lawrence S. Sugiyama, Felicia C. Madimenos, Melissa A. Liebert, Melanie A. Martin, Hillard Kaplan, J. Josh Snodgrass
ESI Publications
Background: The peak shift model predicts that the age-profile of a pathogen’s prevalence depends upon its transmission rate, peaking earlier in populations with higher transmission and declining as partial immunity is acquired. Helminth infections are associated with increased immunoglobulin E (IgE), which may convey partial immunity and influence the peak shift. Although studies have noted peak shifts in helminths, corresponding peak shifts in total IgE have not been investigated, nor has the age-patterning been carefully examined across populations. We test for differences in the agepatterning of IgE between two South American forager-horticulturalist populations and the United States: the Tsimane …

Economics Of Water Use For Commodity Production In Scarcity Arid Regions: Kutum, Darfur, Issam A.W. Mohamed Professor
Economics Of Water Use For Commodity Production In Scarcity Arid Regions: Kutum, Darfur, Issam A.W. Mohamed Professor
Professor Issam A.W. Mohamed
The paper investigates water use in a rural village in semi-arid of Darfur region. Water use is viewed from the perspective of four production sectors: agriculture, rural industry, trade and services as well as domestic: drinking, cooking and sanitary uses. Water for these uses may be from three sources: rain water, surface water, and groundwater. This study focuses on groundwater. Results of a detailed survey indicate that groundwater use is dominated by agricultural activities including irrigated vegetables and grains, tree crops, and animal rearing. A ratio of water use to income generated is used as a measure of water intensity …
Value, Cooperatives, And Class Justice, David Kristjanson-Gural
Value, Cooperatives, And Class Justice, David Kristjanson-Gural
Faculty Journal Articles
In this article I argue that elimination of exploitation at the firm level is necessary to eliminate exploitation, but is not sufficient, in and of itself, to support class justice. I distinguish exploitation as one of several aspects in the more inclusive category of class justice developed by George DeMartino. I then demonstrate that when the formation and distribution of value at the more complex level of Marx’s analysis in volume 3 of Capital is considered, workers may collectively appropriate surplus value but nonetheless be subject to an unfair redistribution of labor time. I use the example of the Mondrago …

Impacts Of The Political Regime On The High Education System Of Sudan, Professor Issam A.W. Mohamed
Professor Issam A.W. Mohamed
In totalitarian systems, especially that of dogmatic nature, education is often targeted to be devoted for the preparations of young generations and dedicating them to the regimes' structure and principles. However, such method negatively influences the educational system and renders the efficient inputs to students. The results can be manifested in deterioration of knowledge, human capital development and the future performance per se.

ESI Publications
The Tsimane of lowland Bolivia are an indigenous forager-farmer population living under conditions resembling pre-industrial European populations, with high infectious morbidity, high infection and inflammation, and shortened life expectancy. Analysis of 917 persons ages 5 to 60+ showed that allele frequencies of 9 SNPs examined in the apolipoprotein E (apoE), C-reactive protein (CRP), and interleukin-6 (IL-6) genes differed from some European, African, and north Asian-derived populations. The apoE2 allele was absent, whereas four SNPs related to CRP and IL-6 were monomorphic: CRP (rs1800947, rs3093061, and rs3093062) and IL-6 (rs1800795). No significant differences in apoE, CRP, and IL-6 variants across age …
Effects Of Social Edification And Family Integration In Military Life In Sudan, Professor Issam A.W. Mohamed
Effects Of Social Edification And Family Integration In Military Life In Sudan, Professor Issam A.W. Mohamed
Professor Issam A.W. Mohamed
The Sudanese army human components are unique in its composition. That is reflected in the country's political and social life. The independence of 1956 means fifty five of turmoil and turbulences. Democratically elected governments controlled the country for only ten years while the military institution's coup de etats took the rest. This paper studies the impacts of social upbringing on the families, military or civilians in order too shed lights on why all military, seemingly are possessed by the illusion of grasping power. The military seems built into the Sudanese society in superior form, i.e., above the law. Thus if …
An Overview Of Economic Patterns Of Partnerships Between Developing And Rich Countries With Special Reference To Usa And Sudan, Issam A.W. Mohamed Professor
An Overview Of Economic Patterns Of Partnerships Between Developing And Rich Countries With Special Reference To Usa And Sudan, Issam A.W. Mohamed Professor
Professor Issam A.W. Mohamed
The current paper presents unique approach to economic analysis where the theoretical framework applied here postulates that relationships between rogue countries, such as Korea, Syria, Iran and Sudan necessarily are potential parts for an economically mutual and viably profitable partnership. The paper reviews such relationships, especially between African and European countries like Lume and kotono. I first present a review of existing trade and economic partnerships. Next, I discuss economic relationships between developed and developing countries. It is revealed that in some instances, the predatory nature of those agreements and partnerships are manifested which atrophy the basic potentials of the …
Opening The System: (Re)Writing Value Theory Discursively, David Kristjanson-Gural
Opening The System: (Re)Writing Value Theory Discursively, David Kristjanson-Gural
Faculty Journal Articles
In this article I argue that modern and postmodern critics of value theory share the premise that Marx’s theory of value disables the project of emancipatory social change. The modern critics claim the theory is logically flawed and must be either resituated in a consistent logical framework or replaced by a Sraffian alternative. The postmodern critics claim that the theory is necessarily reductionist and excludes or renders secondary important axes of social struggle. I argue that by using a poststructural logic, Marx’s theory of value can be interpreted in a way that both overcomes the perceived consistencies of the modern …

Poverty Alleviation, Banks' Structures And Islamic Financing In Sudan, Professor Issam A.W. Mohamed
Professor Issam A.W. Mohamed
The continuous regressions in the per capita income of the Sudanese people have triggered many suggestions to ameliorate their productive capabilities. One of them was the facilitations in financing programs through official channels. However, there are many structural impediments that inhibit those programs. One of the financial programs was the Small or miniature financing in addition to the establishment to specialized Banks as the Family Bank. The current paper discusses issues of financing in Sudan as part of programs initiated to improve income per capita. Islamic and regular financing systems are analyzed in order to explain existing impediments. Then Family …
An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders
An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders
Harry D. Saunders
This paper introduces a new decomposition of energy consumption to reveal the effects of consumer income levels on energy use. It concludes that the great bulk of energy consumption in the US is embedded in goods and services purchased by consumers and that this component of energy demand is growing more rapidly than direct use of energy by households owing to the preferences of high-income consumers. Significantly, this embedded component of energy demand has historically experienced large rebound magnitudes. The analysis also concludes that energy consumption is driven by more than just income level, with the lowest-income consumers using more …
