Maximum Trimmed Likelihood Estimation For Discrete Multivariate Vasicek Processes, Thomas M. Fullerton Jr., Michael Pokojovy, Andrews T. Anum, Ebenezer Nkum

Mathematics & Statistics Faculty Publications

The multivariate Vasicek model is commonly used to capture mean-reverting dynamics typical for short rates, asset price stochastic log-volatilities, etc. Reparametrizing the discretized problem as a VAR(1) model, the parameters are oftentimes estimated using the multivariate least squares (MLS) method, which can be susceptible to outliers. To account for potential model violations, a maximum trimmed likelihood estimation (MTLE) approach is utilized to derive a system of nonlinear estimating equations, and an iterative procedure is developed to solve the latter. In addition to robustness, our new technique allows for reliable recovery of the long-term mean, unlike existing methodologies. A set of …

A Novel Parking Management In Smart City Vehicular Datacenters, Syed Rizvi, Susan Zehra, Steven Olariu

College of Sciences Posters

Researchers have shown that most vehicles spend the majority of their time parked in parking garages, lots, or driveways. During this time, their computing resources are unused and untapped. This has led to substantial interest in Vehicular Cloud, an area of research in which each vehicle acts as a computation node. The main difference between traditional cloud computing and vehicular cloud computing is the availability of nodes. In traditional clouds, nodes are available 24/7, while in vehicular clouds, nodes (vehicles) are only available while parked in parking lots. This creates a dynamic environment as vehicles enter and exit parking garages …

Macroeconomic Aspects Of Maintenance Optimization Of Critical Infrastructures, S. A. Timashev, A. V. Bushinskaya

Engineering Management & Systems Engineering Faculty Publications

The main goal of maintenance is prevention, timely detection and elimination of failures and damage. From the point of view of critical infrastructures (CIs), the main purpose of their maintenance is to increase the safety of CIs and / or to ensure life safety. CIs should be optimal in terms of their purpose, cost, as a source of income and profit at all stages of their life cycle, and also acceptable in terms of possible loss of human lives or injuries. The paper considers the assessment of necessary optimal investments in the maintenance (time interval between subsequent maintenance), to increase …

Health Care Use, Out-Of-Pocket Expenditure, And Macroeconomic Conditions During The Great Recession, Juan Du, Takeshi Yagihashi

Economics Faculty Publications

We study how macroeconomic conditions during the Great Recession affected health care utilization and out-of-pocket expenditures of American households. We use two data sources: the Consumer Expenditure (CE) Survey and the Survey of Income and Program Participation (SIPP); each has its own advantages. The CE contains quarterly frequency variables, and the SIPP provides panel data at the individual level. Consistent evidence across the two datasets shows that utilization of routine medical care was counter-cyclical, whereas hospital care was pro-cyclical during the Great Recession. When we examine the pre-recession period, the relationship between macroeconomic conditions and health care use was either …

Two Essays On The Effect Of Macroeconomic News On The Stock Market, Ajay Kongera

Theses and Dissertations in Business Administration

This dissertation uses macroeconomic variables. In the first essay I use macroeconomic variables to determine if these variables affect the market's returns and volatilities, and in the second essay I examine whether the 11-month returns can be explained by these variables.

Using macroeconomic variables and forecasts of these variables on a quarterly basis from the Survey of Professional Forecasters, I first develop macroeconomic surprise variables. The macroeconomic surprise variables are then modified by dispersion of forecasts to adjust for surprises from uncertainty. Dispersion adjusted forecast surprises have not been used extensively in the literature. I also use a monetary shock …

An Empirical Analysis Of Macroeconomic And Political Determinants Of Private Investment In Sub-Saharan Africa, Ralph Cann-Tamakloe

School of Public Service Theses & Dissertations

The general macroeconomic and political difficulties experienced by many Sub-Saharan African countries in the late 1980s has led to economic and political reforms to improve private investment performance. It has been estimated that Sub-Saharan African countries needed to boost private investment in gross domestic product some 25% in the 1990s to achieve sustainable growth and development (Pfefferman and Madarassy, 1989). However, private investment performance has fallen short of the estimated 25%, and remained stagnant between 12.4% and 14.1% per annum from 1993 to 2002.

The purpose of this study therefore is to examine the influence of macroeconomic factors and democracy, …

The Effects Of Local And Global Risk Factors On Industry Stock Returns: Across Country Analysis, Mahdy Farag Elhossiny

Theses and Dissertations in Business Administration

This dissertation studies the local and global sources of risk and industries stock returns across national equity markets. We examine several local and global economic risk factors and ask whether and to what extent these risk factors can explain the variation in the industries' stock returns of five countries, namely Canada, Germany, Japan, the U.K., and the U.S. Specifically, the main objective of this dissertation is to find answers for three main questions: First, whether and to what extent do returns on local industries respond to changes in local macroeconomic risk factors? Second, whether and to what extent do returns …
