We study the Bertrand equilibrium in duopoly in which two firms produce a homogeneous good under quadratic cost functions, and they seek to maximize the weighted sum of their absolute and relative profits. We show that there exists a range of the equilibrium price in duopolistic equilibria. This...

: The concept of rethinking, reorganizing or reengineering dysfunctional business processes has been approached from many aspects both by professionals and academic researchers. However, service processes do not get as much attention as their importance would deserve. One reason can be the usage...

The authors study pure strategy Bertrand equilibria in a duopoly in which two firms produce a homogeneous good with convex cost functions, and they seek to maximize the weighted sum of their absolute and relative profits. They show that there exists a range of the equilibrium price in...

The study used a sample of 188 maize farmers to determine the economic efficiency of maize production in Swaziland. Descriptive statistics, Cobb-Douglas production function and Tobit regression were used to analyse the data. The results indicated technical efficiency of 64.7% suggesting that...

In this paper we propose an approach to evaluation of the environmental effects of consumption goods. The approach consists of two steps, namely (1) an assignment of environmental effects of different types to the consumption activities, followed by (2) a comparison of the consumption activities...

This study examines the relative performance of Japanese cooperative banks between 1998 and 2009, explicitly modeling non-performing loans as an undesirable output. Three key findings emerge. First, the sector is characterized by increasing returns to scale which supports the ongoing...
