A sustainable energy system is key for addressing the world’s environmental and social challenges. The U.S is the second largest consumer of energy, with increased energy consumption in the previous half-century. To curb energy demand, it is essential to understand the relative price...

Agricultural production is often exposed to several sources of risks, uncertainties and random shocks. These risks and random shocks make the evaluation the influence of policy interventions in the agricultural sector difficult due to the existence of limited data about random events....

This paper examines the possibility that insurance for row crops, livestock, and aquaculture can be used effectively to encourage producers to adopt practices that will improve environmental behavior. Examples of agricultural environmental insurance are provided and considered in the context of...

In this paper, we estimate the time-varying betas or input elasticities and returns to scale in a stochastic frontier cumulative rolling regression analysis framework using FAO data of Southeast Asian countries from 1960-2002. Empirical results indicated returns to scale are overestimated by...

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...

Here, using input, output and nitrogen pollution data related to one state, we propose to extend the elasticity concept to include environmental pollution treated as undesirable output to provide the environmentally adjusted elasticity measures for the period, 1936-1997 in a two-step procedure.

This paper has a three fold contribution to the existing literature - 1) Indian state level sorghum input and output data for the period 1970-71 to 2000-01 is collected, 2) non-parametric linear programming productivity measures are estimated, and 3) examine the impact of policy variables like...

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...

The purpose of this study is to evaluate the technical efficiency of trucking carriers on a national basis by commodity groups for the year 2001. In this analysis, the efficiency measures are estimated using stochastic frontier analysis. Results reveal efficiency measures of trucking carriers...
