Abstract: This paper attempts to identify the significance of
Information and Communications Technology (ICT) and
competitiveness to the profit efficiency of commercial banks in
Malaysia. The profit efficiency of commercial banks in Malaysia, the
dependent variable, was estimated using the Stochastic Frontier
Approach (SFA) on a sample of unbalanced panel data, covering 23
commercial banks, between 1995 to 2007. Based on the empirical
results, ICT was not found to exert a significant impact on profit
efficiency, whereas competitiveness, non ICT stock expenditure and
ownership were significant contributors. On the other hand, the size
of banks was found to have significantly reduced profit efficiency,
opening up for various interpretations of the interrelated role of ICT
and competition.
Abstract: Environmental factors affect agriculture production
productivity and efficiency resulted in changing of profit efficiency.
This paper attempts to estimate the impacts of environmental factors
to profitability of rice farmers in the Red River Delta of Vietnam. The
dataset was extracted from 349 rice farmers using personal
interviews. Both OLS and MLE trans-log profit functions were used
in this study. Five production inputs and four environmental factors
were included in these functions. The estimation of the stochastic
profit frontier with a two-stage approach was used to measure
profitability. The results showed that the profit efficiency was about
75% on the average and environmental factors change profit
efficiency significantly beside farm specific characteristics. Plant
disease, soil fertility, irrigation apply and water pollution were the
four environmental factors cause profit loss in rice production. The
result indicated that farmers should reduce household size, farm
plots, apply row seeding technique and improve environmental
factors to obtain high profit efficiency with special consideration is
given for irrigation water quality improvement.
