The prime objective of this paper is to empirically investigate the nature of technological progress in selected STUs. To examine this issue, a translog cost function is estimated jointly with factor share equations subject to required coefficient restrictions by using the method of 'Zellner's...

The prime objective of this paper is to empirically investigate the nature of scale economies in State Transport Undertakings (STUs) in India on the basis of a sample of medium- and large-size Indian states for which consistent data are available. To examine this issue, a translog cost function...

We estimate the effect of Internet on volume of trade in a major distributed marketplace. From 1997 to 2007, a period during which residential Internet use tripled, Internet increased the volume of used cars traded in California by 7.2 percent. This implies a substantial welfare gain due to...

Different social sciences study human beings. Economics is one of them and it is focused on a specific field of human action and social cooperation. The entire human collaboration is based on significant moral and ethical standards. If we want to understand how people are involved in economic...

A theoretical model is adopted in order to examine optimal fare and optimal quality of supply schemes for a transport operator. The analysis shows how fares and quality of supply are related to travel distance and to the transport operator's weight on profit versus consumer surplus. Under...

While the Telecommunications Act of 1996 introduces competition into local telephone markets at a national level, prior to the Act many states had already restructured their regulatory methods. In particular, many states allowed for competition in both local service and "local long distance"...

Theoretical models of spatial competition usually assume an uniform consumer distribution. In the real world, firms frequently compete for consumers who are not uniformly located. The equilibrium duopoly locations of several types of commonly used distributions were discussed in Meagher, Teo and...
