Abstract

Container terminal efficiency is a critical factor in the contemporary global trade. We apply the DEA and SFA methods to evaluate efficiency of 6 major ports in the West Africa region to investigate whether these ports can become the main hubs of container transport to African inland in the future. The DEA and SFA methods were applied to a number of inputs such as total quay length; total terminal area, number of quayside cranes, number of gantry cranes and number of reach stackers and single output, to measure efficiency.

Abstract

The overall globalization in wine industry and the search for sustainability of the sector has increased competition which highlights the importance of productivity gains. The purpose of this paper is to analyse the productive efficiency of the viticulture sector for the Portuguese regions, over the period 1989 to 2007, with data from the EUFADN, using both a deterministic and stochastic approach. The results show an increase of Technical Efficiency (TE) when used the stochastic frontiers analysis (SFA) in all regions, while the data envelopment analysis (DEA) approach through the Malmquist index reveals a stabilization of TE.

Keywords: Efficiency, productivity, Portuguese regions, viticulture.

Abstract

Urban pollution continues to be a crucial issue in cities across the globe, especially in developing countries. Examining the effect pollution tax has on a firm’s decision to locate closer/further to the urban centre will be worthy from an environmental preservation perspective. This paper analyses the relationship between pollution tax and the firm’s location when considering the firm’s efficiency of pollution abatement and its efficiency of production. The results find that a firm which has exhibited increasing returns to scale in pollution abatement performance in response to pollution tax increases its output level. It also shows that the firm’s location depends on the efficiency of pollution abatement and production efficiency. The changes to pollution level at the urban centre due to pollution tax depends on the changes to the firm’s output level, the firm’s location choice, and the firm’s pollution abatement performance.
