The purpose of this study is to investigate the issue of efficiency in the U.S. motor carrier industry using DEA and SFA. While both methods used the same variables, the resulting efficiency scores were significantly different. This leads to the question of which method is a better measure of...

Using an econometric model the economic impact of the September 11, 2001(9/11) terrorists' attacks on the U.S. homeland on the trucking transportation sector in the United States is examined. Also, the econometric model was modified to show how this event may have inflicted economic damage on...

Dynamic shift-share analysis reveals that national growth effects were positive while industrial mix, competitive, and allocation effects were negative. Results also show the time(technology) variable were significantly and positively related to the competitive effects for coal, chemical...

The purpose of this study was to estimate the impact of internal and external variables on the net profit margins of Class I railroads for the period 1996-2009. Parameter coefficients show that market concentration had a significant and negative impact on the net profit margins of the carriers.

The overall objective of this paper is to measure the impact of the undesirable outputs from NAFTA (agricultural production and trade) on the environment by years in post-NAFTA period. Data Envelopment Analysis (DEA) was used to measure environmental efficiency by considering desirable (corn...

The primary objective of this study is to empirically determine whether North American Free Trade Agreement (NAFTA) has contributed to increased agricultural productivity in any of its member countries. Implementation of the NAFTA began on January 1, 1994. This agreement removed most barriers to...

The potential impact of a BSE outbreak on the US economy is modeled in input-output setting using 2002 US IMPLAN data. An outbreak of BSE would hurt the US beef industry, other agriculturally-related industry, and the rest of the economy as a whole. The worse effects occur in the beef cattle and...

In this paper, the impact of entry and exit of firms on the overall efficiency of the industry is examined in the efficiency framework, using agribusiness-trucking firms for the period 1994-2003. Specifically, industry efficiency is compared with and without firms that enter and exit using panel...

Econometric models were developed to estimate factors that influence strategic changes and evaluate the impacts that strategic changes will have on the subsequent performance of agricultural commodity trucking firms. Results reveal that GDP and change in firm size will have positive impacts on...
