Asean+3 Monetary And Financial Integration: What We Need For A New Framework?, Reza Moosavi Mohseni

Reza Moosavi Mohseni

In this paper at first we investigate the viability of creating an optimum currency area (OCA) in the East Asia. Then we try to find the currency bloc which is more suitable for this region. A ten-variable VAR model employed to estimate the underlying shocks and test the symmetry of them. The results show that forming an OCA for all of the countries in the region is costly and difficult to sustain. But at first five countries called Japan, China, Korea, Malaysia, and the Philippine with symmetric supply shocks can create the single currency area. The rest of the countries …

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.

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 …

Empirical Methods For Predicting Student Retention- A Summary From The Literature, Matt Bogard

Economics Faculty Publications

The vast majority of the literature related to the empirical estimation of retention models includes a discussion of the theoretical retention framework established by Bean, Braxton, Tinto, Pascarella, Terenzini and others (see Bean, 1980; Bean, 2000; Braxton, 2000; Braxton et al, 2004; Chapman and Pascarella, 1983; Pascarell and Ternzini, 1978; St. John and Cabrera, 2000; Tinto, 1975) This body of research provides a starting point for the consideration of which explanatory variables to include in any model specification, as well as identifying possible data sources. The literature separates itself into two major camps including research related to the hypothesis testing …

Forest Biomass Utilization In The Southern United States: Resource Sustainability And Policy Impacts, Zhimei Guo

Doctoral Dissertations

As an alternative renewable source for bioenergy, forest biomass has recently drawn more attention from the U.S. government and the general public. Woody biomass policies have been adopted to encourage the new bioenergy industry. A variety of state policy incentives attempt to create a desirable legal climate and lure new firms, imposing two important questions regarding state government policies and the sustainable use of forest resources. This dissertation sheds some light on these questions.

The first paper constructs a woody biomass policy index through scoring each statute and weighting different categories of policies from the vantage point of renewable energy …

Instrumental Variable Quantile Estimation Of Spatial Autoregressive Models, Liangjun Su, Zhenlin Yang

Research Collection School Of Economics

We propose a spatial quantile autoregression (SQAR) model, which allows cross-sectional dependence among the responses, unknown heteroscedasticity in the disturbances, and heterogeneous impacts of covariates on different points (quantiles) of a response distribution. The instrumental variable quantile regression (IVQR) method of Chernozhukov and Hansen (2006) is generalized to allow the data to be non-identically distributed and dependent, an IVQR estimator for the SQAR model is then defined, and its asymptotic properties are derived. Simulation results show that this estimator performs well in finite samples at various quantile points. In the special case of spatial median regression, it outperforms the conventional …

Industrial Diversity And Economic Performance: A Spatial Analysis, Hoa Phu Duy Tran

College of Business: Dissertations, Theses, and Student Research

This study examines the linkage between industrial diversity and economic growth in the 48 contiguous states of the United States. The period of analysis is 1992 through 2009. Five diversity indices are considered and economic growth is measured as the growth rate of nonfarm earnings. Other variables thought to influence economic growth are included in the analysis. They are the growth rate of nonfarm employment, capital, and farm earnings. Tests for the endogeneity of variables are conducted and the need for instrumental variable estimation methods is demonstrated.

First, I consider multivariate model that relates nonfarm earnings growth to the diversity …

Status Of Usa Rebound Effect Activities: The Debate, The Progress, Harry D. Saunders

Harry D. Saunders

This presentation describes the nature of the rebound debate in the United States in 2011, provides estimates of US rebound, compares embedded vs. end use energy, and estimates the economic costs of taxes aimed at mitigating rebound effects.

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 …

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

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 …

Target Industry Study: An Empirical Analysis Of Intertemporal Trends In Regional Industrial Base Composition, David M. Smith

Undergraduate Theses and Capstone Projects

This paper follows existing literature on local industrial conditions and agglomeration economies in an adapted shift-share framework. The purpose of this study is to develop a cost-efficient empirical model that meets the needs of local government in analyzing changes in industrial composition. The data for this model is obtained from the Bureau of Labor Statistics' Quarterly Census of Employment and Wages (QCEW) with nondisclosed data provided by the Virginia Employment Commission which is sorted by North American Industrial Classification System (NAICS) 2-digit industrial sectors. The model developed in this paper identifies certain industrial sectors which exert significant influence on the …

Infinite Density At The Median And The Typical Shape Of Stock Return Distributions, Chirok Han, Jin Seo Cho, Peter C. B. Phillips

Research Collection School Of Economics

Statistics are developed to test for the presence of an asymptotic discontinuity (or infinite density or peakedness) in a probability density at the median. The approach makes use of work by Knight (1998) on L(1) estimation asymptotics in conjunction with nonparametric kernel density estimation methods. The size and power of the tests are assessed, and conditions under which the tests have good performance are explored in simulations. The new methods are applied to stock returns of leading companies across major U.S. industry groups. The results confirm the presence of infinite density at the median as a new significant empirical evidence …

Bias In Estimating Multivariate And Univariate Diffusions, Xiaohu Wang, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

Multivariate continuous time models are now widely used in economics and finance. Empirical applications typically rely on some process of discretization so that the system may be estimated with discrete data. This paper introduces a framework for discretizing linear multivariate continuous time systems that includes the commonly used Euler and trapezoidal approximations as special cases and leads to a general class of estimators for the mean reversion matrix. Asymptotic distributions and bias formulae are obtained for estimates of the mean reversion parameter. Explicit expressions are given for the discretization bias and its relationship to estimation bias in both multivariate and …

Asymptotic Theory For Zero Energy Functionals With Nonparametric Regression Applications, Qiying Wang, Peter C. B. Phillips

Research Collection School Of Economics

A local limit theorem is given for the sample mean of a zero energy function of a nonstationary time series involving twin numerical sequences that pass to infinity. The result is applicable in certain nonparametric kernel density estimation and regression problems where the relevant quantities are functions of both sample size and bandwidth. An interesting outcome of the theory in nonparametric regression is that the linear term is eliminated from the asymptotic bias. In consequence and in contrast to the stationary case, the Nadaraya-Watson estimator has the same limit distribution (to the second order including bias) as the local linear …
