Tariffs for international mobile roaming (IMR) are often viewed by governments as an additional tax on international trade and on tourism. IMR customer bills may appear to be arbitrary and sometimes excessive. The purpose of this paper is therefore to set out a pragmatic approach to assessing international charges for mobile roaming, making use of a realistic cost model of the international roaming process and its cost elements, at a level that is useful to regulatory authorities and operators.

The discussion presented is based on industry practices for handling voice calls and data sessions with the mobile network operators (MNOs) business model, based on industry sources. The basic mechanisms use two common constructs from business analysis – business processes and use-cases – to provide a simplified form of activity-based costing. This provides a model suitable for national regulatory authorities to move towards cost-based IMR tariffs.

Using a perspective on costs based on a bottom-up survey procedure for elucidating the key information, the paper presents the cost elements for the various IMR network components and business processes, with an approach suitable for analysing both wholesale and retail pricing.

The method is specifically designed to overcome the key problem of such approaches, the limitations set by differences in network technologies, network topology, operational scale and the engineering, as well as MNO business model and accounting practices, which otherwise would preclude the method presented here from being vendor neutral.

Vendor and network engineering neutrality implies the approach can be used to compare different MNOs in terms of the validity of their IMR charges and whether they are cost based.

Impacts on society of so-called “bill-shock” have become quite common, increasingly for data sessions. The cost model presented here was developed with the intention of improving the accountability and transparency of the mobile roaming market. It thus assists in the introduction of cost-based tariffs over an economic region, such the European Union.

The paper examines the practical implications of building large-scale cost models for assessing the real IMR costs, a modelling exercise that has not been seen elsewhere in terms of its approach and neutrality as to MNO structure and assets.

The purpose of this paper is to review the economic arguments for and against raising the tariff on imports of cotton into China.

The paper reviews first the possible arguments for raising the tariff, and particularly the possibility that such an increase in tariffs would have a favorable distributional effect by redistributing from those involved in the production of textiles and clothing to the producers of cotton. The core analysis of the paper examines the policies in place using descriptions of policies and interviews with policymakers. It also assembles statistics designed to assess the export status of cotton, whether in raw or processed form.

The paper reviews the situation with respect to WTO commitments and confirms that such an increase, up to 40 percent, would be permitted under WTO rules. The paper then examines other constraints on the effective use of such higher tariffs on cotton. Policies that are better than tariff increases in dealing with the serious problems of rural incomes are identified.

The paper is unable to assess the distributional impacts of an increase in the tariff on cotton. It raises a number of cautions about the issues that need to be confronted in making such an assessment.

The issue of raising the tariff on cotton has been a subject of intense debate in China and this paper is intended to provide an input into this debate. The paper agrees that urgent action is clearly needed to mitigate the poverty problems in rural China, but concludes that a number of policy options appear likely to be more effective in dealing with these problems than protection of cotton.

Substantial economies can be achieved by judicious selection of energy tariffs. National Utility Service, international tariff analysts, saved 3,000 clients in the United Kingdom and Ireland £6 million on energy bills last year, but making the most of the tariff system is a full‐time job.

Chester Whitney Wright (1879–1966) received his A.B. in 1901, A.M. in 1902 and Ph.D. in 1906, all from Harvard University. After teaching at Cornell University during 1906–1907, he taught at the University of Chicago from 1907 to 1944. Wright was the author of Economic History of the United States (1941, 1949); editor of Economic Problems of War and Its Aftermath (1942), to which he contributed a chapter on economic lessons from previous wars, and other chapters were authored by John U. Nef (war and the early industrial revolution) and by Frank H. Knight (the war and the crisis of individualism); and co-editor of Materials for the Study of Elementary Economics (1913). Wright’s Wool-Growing and the Tariff received the David Ames Wells Prize for 1907–1908, and was volume 5 in the Harvard Economic Studies. I am indebted to Holly Flynn for assistance in preparing Wright’s biography and in tracking down incomplete references; to Marianne Johnson in preparing many tables and charts; and to F. Taylor Ostrander, as usual, for help in transcribing and proofreading.

One of the major objectives of India's National Auto Policy (NAP) (2018) is to help the country emerge as a hub for automotive production and research and development (R&D). In order to fulfill this long-term objective, two policies had been proposed by NAP (2018). First, possibility of exploring regional trade agreements (RTAs) with leading countries, having attractive markets for Indian players, was considered. Second, the policy aimed to evaluate the potential implications of joining the United Nations Economic Commission for Europe (UNECE) WP.29 1958 agreement within the next 5 years for tackling the potential major technical barriers to trade (TBT), as India's current accession in UNECE WP.29 1998 agreement may not be sufficient for ensuring mutual recognition of standards in many of the partner countries. India is presently engaged in RTA negotiations with several developed and developing countries, with potentially beneficial repercussions for automobile exports. However, the question of accession to UNECE WP.29 1958 agreement has not received similar attention of late, which may restrain the anticipated sectoral export growth, particularly through RTA-led market access outcomes. Given this background, the current analysis considers India's potential sectoral trade growth with eight partner countries, in the case of RTA-led tariff reforms, through a WITS-SMART simulation exercise. The obtained simulation results indicate that India needs to focus on the technical standard harmonization question for reaping the full benefits arising from tariff reforms in several upcoming RTAs, for boosting auto-exports in the post-RTA period.

The chapter attempts to develop a micro-theoretic model to explain the genesis of trade war in light of the behavioral interdependence of two countries connected through international trade and, thereof, it analyses its welfare implication with respect to the countries at feud. In this regard, it is important to mention that the evolution of trade war herein has been articulated in terms of the retaliation of one country as reaction to the one time-tariff imposition by the other. The fundamental takeaways are twofold. First, how evolution of tariff war can be articulated in light two-stage game governments are coming to decide on tariff policy a priori, followed by second-stage featuring firms being decisive on the production level and then the games repeats where governments again come up to introspects if the a priori tariff rates are compatible with welfare optimization to be followed up by firms. Second, the nature of the ultimate fallout of the tariff retaliation will depend crucially on how welfare function of each country is paced with the country’s tariff policy.

The purpose of this paper was to understand the experience of those living with the Imprisonment for Public Protection (IPP) sentence.

Interpretative Phenomenological Analysis (IPA) was used to analyse seven interviews with Young Offenders aged 18-21 who were serving an IPP sentence. Two participants were past their tariff expiry date, two had less than a year until their tariff date and three had more than a year until their tariff date.

Several themes were found, each with their own subthemes: Injustice of the Justice System, Not Knowing, Coping, Change and Walking on Eggshells. Participants still detailed negative aspects of the sentence but within this was one, important, positive aspect, namely the inspiration the sentence gave for them to change their offending behaviour. However, this has come at a cost with participants feeling as though they have been treated unfairly, finding it difficult to cope, feeling victimised and finding it difficult to see a future.

Lapses in motivation do not necessarily reflect the risk of the person but the difficulty of the sentence. Motivation can be fostered and developed through motivational interviewing, praise and peer support IPPs should be given more credit for the way they manage themselves daily and more understanding when they struggle. IPPs could be victimised by determinate prisoners or by staff. Establishments should be aware of this and help IPPs resolve situations without feeling like they are a victim. Consideration should be given to converting IPP sentences to determinate sentences.

Previous research focused on the negative aspects of the sentence, the purpose was therefore to approach the situation with an open mind and by using a method that allows those with an IPP sentence to share their experience of the sentence. IPA allowed for exploration of the effects of the sentence on those serving it and therefore gains a further understanding of the impact of the sentence.
