In production economics, little attention is paid to transportation costs in any discussion of cost minimization by the firm. When the output is produced at multiple locations, transportation costs can become quite important in light of the geographical dispersion of plants and markets. In...

The dual cost function is partially super-additive when an output quantity bundle of a given quality can be produced at a lower cost by breaking up the output into a number of smaller bundles of the same quality to be produced by several firms instead of the entire bundle being produced by a...

Varian's Weak Axiom of Cost Minimization provides a nonparametric test of cost minimization, which can be applied only when both input price and quantity data are available for individual firms. In this paper we propose a Weak Axiom of Cost Dominance (WACD), which serves as the basis of an...

In parametric analysis based on a frontier production function, usually the scale elasticity rather than scale efficiency level is reported. In this paper we show how one can use an estimated translog production function to obtain output- and input-oriented measures of scale efficiency at an...

In nonparametric analysis of production efficiency, the focus of attention is typically on the individual firm. In this article, we evaluate efficiency in resource utilization at the industry level. We propose an integer programming model to measure the extent of input saving possible if the...

Over the past decades Data Envelopment Analysis (DEA) has emerged as an important nonparametric method of evaluating performance of decision making units through benchmarking. Although developed primarily for measuring technical efficiency, DEA is now applied extensively for measuring scale...

In the present study we evaluate the overall cost efficiency of a network of branches of a single large public sector bank in India within the city of Calcutta using the data for the year 2012. Our objective is to determine the optimal number of branches within a postal district that could...

In this paper technical efficiency is introduced via the intercept that evolve over time as a AR(1) process in a stochastic frontier (SF) framework in a panel data framework. Following are the distinguishing features of the model. First, the model is dynamic in nature. Second, it can separate...

Using the non parametric approach of Data Envelopment Analysis (DEA) this paper examines firm’s heterogeneity in the Indian pharmaceutical industry by measuring their input and output efficiencies for the period 1991 to 2005. The analysis establishes that even though firms have been able to...

In most countries the government is empowered by the Constitution to acquire privately owned land for public use on payment of fair compensation for the land acquired. For infrastructure projects like a highway or a dam, the land acquired remains under public ownership. In many cases, however,...
