We use a simple framework where firms in two countries serve their respective domestic markets and a world market to analyze under which conditions cost-reducing mergers will be beneficial for the merging firms, the home country, and the world as a whole. For a national merger, the policies enacted by a national merger authority tend to be overly restrictive from a global efficiency perspective...

This paper tries to reconcile reciprocity with a fundamentally `subjectcentred' ethic by interpreting the reciprocity condition as a consequence of the fact that justice is in part a relational value. Duties of egalitarian distributive justice are not grounded on the duty to reciprocate bene ts already received, but limited by a reasonable assurance of compliance on the part of those able to re...

In Australia, Japan, Sweden, and Switzerland, the average life expectancy is now greater than 80 years. But in Angola, Malawi, Sierra Leone, and Zimbabwe, the average life expectancy is less than 40 years. The situation is even worse than these statistics suggest because average figures tend to mask inequalities within countries. What are we to make of a world with such inequal health prospects...

One of the key issues for transportation companies is to produce an optimal plan for the work of crew members. Crew planning consists of a sequence of phases, the first two corresponding to planning duties (sequences of trips to be done by crew members from their home base to their home base) and planning rosters (sequences of duties and rest days to be followed by crew members during a certain...

In response to the growing contribution of the trucking sector to global warming and local air quality impacts, many nations and regions around the world have developed programs and policies to improve the environmental performance of heavy-duty vehicle fleets. To date, Japan, the U.S., Canada, and China have enacted mandatory fuel efficiency or greenhouse gas (GHG) standards for new heavy-duty...

This paper presents global scenarios of sulphur dioxide (SO(2)), nitrogen oxides (NO(x)), and particulate matter (PM) emissions from road transport through to 2050, taking into account the potential impacts of: (1) the timing of air pollutant emission regulation implementation in developing countries; (2) global CO(2) mitigation policy implementation; and (3) vehicle cost assumptions, on study ...

In this paper, the Vector Based Swarm Optimization method is used for designing an optimal controller for the maximum power point tracker of a stand-alone PV System. The proposed algorithm is executed on vectors in a multi-dimension vector space. These vectors by appropriated orientation converge to a global optimum while the algorithm runs. The Remarkable point of the VBSO algorithm is how us...
