Employing the error correction method and historical decomposition with direct acyclic graphs, we quantify the impacts of domestic and overseas animal disease crises on the Korean meat market. We have the following findings: (a) the market partially recovered 16 months after the domestic...

Causal relationships are used to investigate information flows and directions of control in a decentralized multi-echelon supply chain where no central authority has system level control over optimizing decisions. We use secondary time-series data representing the US beef industry to investigate...

Among the various ocean energy resources in Korea, the tidal currents in the South western sea have a large potential for development tidal current power generation. The biggest advantage of tidal power is that it is not dependent on seasons or weather and is always constant. This makes power...

Since Georgia unveiled its HOPE Scholarship in 1993, at least 15 other states have implemented or proposed merit-aid programs based on the HOPE model. A common justification for these actions is to promote and reward academic achievement, thereby inducing greater investments in human capital....

A common justification for HOPE-style merit-aid programs is to promote and reward academic achievement, thereby inducing greater investments in human capital. However, grade-based eligibility and retention rules encourage other behavioral responses. Using data extracted from the longitudinal...

A common justification for HOPE-style merit-aid programs is to promote and reward academic achievement, thereby inducing greater investments in human capital. However, grade-based eligibility and retention rules encourage other behavioral responses. Using the longitudinal records of all...

A common justification for state-sponsored merit scholarships like Georgia’s HOPE program is to promote academic achievement. However, grade-based retention rules encourage other behavioral responses. Using longitudinal records of enrolled undergraduates at the University of Georgia between...

This study proposes a semiparametric estimate and a test for base-independence equivalence scale. Our semiparametric approach is based on nondensity weighted loss function in contrast to Pendakur's (1999) density weighted loss function. Simulation results indicate that our specification tends to...

This study compares parametric and nonparametric quantile regression methods using Monte Carlo simulations. Simulation results indicate that the nonparametric quantile regression approach is more appropriate, particularly when the underlying model is nonlinear or the error term follows a...
