This article investigates the critical issue of how Appalachian coal supply flows vary in response to changes in national coal markets and policies, with emphasis on the relative stability of traditional flows. The approach taken to analyze this stability involves the use of a quadratic...

The main objective of the paper is to decipher the military expenditure--economic growth relationship, taking the level of economic development (income) into consideration. Our findings suggest the following: (i) military expenditure has a significantly negative relationship to economic growth...

This paper replicates two spatial monopoly models by Takayama and Judge. The first one is a simple spatial monopoly model. The second model allows the activity of arbitrage between any pains of consumption regions if the price differential exceeds the corresponding unit transportation cost. With...

The combinatorial nature of integer programming is inevitable even after takingspecific model structure into consideration. This is the root problem in implementing large-scale nonlinear integer programming models regardless of which algorithm one chooses to use. Consequently, we suggest that...

It has been long recognized that an ad valorem tax rate on revenues (demand) has its counterpart in costs (supply). Such a one to one correspondence is referred to as the Musgravian transformation. The transformation is monotonic and nonlinear. However, the property of concavity of the tax...
