Q3 Economics, Econometrics and Finance Pub Date : 2020-03-30 DOI: 10.55596/001c.116307
Chappell Lawson, Alan Bersin
This article challenges the conventional approach to border management, which despite many innovations in recent decades still involves unilateral efforts to protect territorial boundaries. A better alternative for neighbouring country-dyads, wherever the prospect of war has become implausible, is collaborative border management. This approach involves extensive, deep collaboration to facilitate legitimate trade and travel through authorized ports of entry, combat transnational criminal activity, and manage crossborder ecological resources.
尽管近几十年来进行了许多创新,但边界管理的传统方法仍然是单方面努力保护领土边界。对于邻国来说,只要战争的前景已变得不可信,更好的替代办法就是合作式边境管理。这种方法涉及广泛、深入的合作,通过授权入境口岸促进合法贸易和旅行,打击跨国犯罪活动,管理跨境生态资源。

The Extent of the Illicit Cigarette Market in Australia: Using Publicly Available Data in a ‘Top-Down’ Approach to Estimation 澳大利亚非法卷烟市场的规模:利用公开数据进行 "自上而下 "的估算

There have been several recent attempts to estimate the size of the Australian illicit tobacco market. The two most recent studies have provided significantly different results, with the Australian Taxation Office (ATO) arriving at an estimate of 5 per cent as the extent of the illicit component of the market, while a tobacco industry–funded approximation conducted by KPMG has suggested this figure to be 14.1 per cent. This paper investigates whether a new methodology for undertaking such an estimate could produce more accurate results and examines publicly available information to explore if there are datasets that could help determine which estimate of the illicit market may be more accurate. The resulting ‘top-down’ approach identifies an estimate lying between the ATO and KPMG estimates, although it is limited to the illicit cigarette market in Australia. Implications of the results are discussed, and suggestions for further research are presented.
最近曾多次尝试估算澳大利亚非法烟草市场的规模。澳大利亚税务局(ATO)估算的非法烟草市场规模为 5%,而毕马威会计师事务所(KPMG)由烟草业资助进行的近似估算则认为这一数字为 14.1%。本文探讨了采用新方法进行估算是否能得出更准确的结果,并研究了可公开获得的信息,以探讨是否有数据集可帮助确定哪种非法市场估算可能更准确。由此产生的 "自上而下 "方法确定了介于 ATO 和毕马威会计师事务所估算之间的估算值,尽管该估算值仅限于澳大利亚的非法香烟市场。讨论了结果的影响,并提出了进一步研究的建议。

The Role and Importance of Customs Representation to the Old Customs Control System in the Republic of Bulgaria 海关代表处对保加利亚共和国旧海关监管系统的作用和重要性

The complex nature of foreign trade operations and related customs formalities are some of the prerequisites giving rise to the need for customs representation to form part of the customs process. Such representation is a necessary part of international supply chains, as the requisite professional knowledge in the sphere of customs compliance serves to protect the interests of both the economic operators involved and the state represented by the customs administration. The services provided by the customs representatives facilitate the smooth passage of the consignments through the relevant customs formalities, lead to a reduction in the time for customs clearance and, through consultation, lead to increasing the wellbeing of the economic operators who trust them. At the same time, customs administrations generally have a trustworthy and predictable partner: the customs representative who understands the customs formalities and actively assists in fulfilling the tasks and objectives assigned to them. In the context of the Republic of Bulgaria, customs representatives play an important role in customs procedures and participate in a substantial part of import, export and transit operations.
外贸业务的复杂性和相关的海关手续是导致海关代理成为海关流程一部分的先决条件。这种代理是国际供应链的必要组成部分,因为海关合规方面的必要专业知识有助于保护相关经济运营商和海关管理部门所代表的国家的利益。海关代表提供的服务有助于货物顺利通过相关的海关手续,缩短通关时间,并通过协商提高信任他们的经济经营者的福利。同时,海关管理部门一般都有一个值得信赖和可以预测的合作伙伴:海关代表,他了解海关手续并积极协助完成分配给他的任务和目标。在保加利亚共和国,海关代表在海关程序中发挥着重要作用,并参与了进口、出口和过境业务的很大一部分。

Tariff Barriers and Non-Tariff Barriers: Appraising Colombia’s Protectionism 关税壁垒与非关税壁垒:评估哥伦比亚的保护主义

Tariff barriers (TBs) are regulated under the provisions of the General Agreement on Tariffs and Trade (GATT), such as the most-favoured-nation treatment article, which establishes that trade concessions granted to one member are applied immediately and without conditions to all other members. Likewise, the schedule of concessions on goods, which indicates that all trade concessions made by members must be reported under the legal agreement’s ‘bound’ rates. Then, if one World Trade Organization (WTO) member raises applied tariffs above their bound level, any WTO member can sue the country for this action. However, on the other hand, the non-tariff barriers (NTBs) are more complex to regulate due to a state’s ability to adopt many different new measures, which makes the measures hard to identify as barriers. Furthermore, the opacity of many NTBs also makes enforcement of regulations a complicated international endeavour. Thus, the international trading system assumes that there will be essential challenges and seeks to develop explicit provisions for this kind of protectionism. This paper, which is based on the findings of a comprehensive review of Colombia’s situation, provides a general explanation of TBs and NTBs as protectionist measures within the foreign trade of this Latin American country. In doing so, the research identifies the TBs and NTBs currently adopted, the effects of these barriers on this economy, and the sectors that are meaningfully affected by these measures.
关税壁垒(TBs)受《关税及贸易总协定》(GATT)条款的制约,如最惠国待遇条款,该条款规定给予一个成员的贸易减让应立即无条件地适用于所有其他成员。同样,货物减让表也规定,各成员做出的所有贸易减让都必须按照法律协定的 "约束 "税率进行报告。那么,如果世界贸易组织(WTO)的某一成员将适用关税提高到约束水平以上,任何 WTO 成员国都可以对该国的这一行为提起诉讼。但另一方面,非关税壁垒(NTBs)的监管更为复杂,因为一个国家可以采取许多不同的新措施,这使得这些措施很难被认定为壁垒。此外,许多非关税壁垒的不透明性也使得法规的执行成为一项复杂的国际工作。因此,国际贸易体系假定会存在基本的挑战,并试图为这类保护主义制定明确的规定。本文基于对哥伦比亚情况的全面审查结果,对作为拉美国家外贸保护主义措施的贸易壁垒和非关税壁垒进行了一般性解释。在此过程中,研究确定了目前采用的贸易壁垒和非关税壁垒、这些壁垒对经济的影响以及受这些措施影响的部门。

In the Name of Legal Certainty? Comparison of Advance Ruling for Tariff Classification Systems in the European Union, China and Taiwan 以法律确定性的名义?欧盟、中国和台湾地区关税分类制度预先裁定的比较
Q3 Economics, Econometrics and Finance Pub Date : 2016-08-29 DOI: 10.2139/SSRN.2831508

In many jurisdictions, international traders can apply to customs authorities for an advance ruling for tariff classification before they import or export their goods. The advance ruling system for tariff classification is expected to grant more legal certainty to international traders because they can communicate with customs authorities and receive a legally binding tariff classification decision in advance. Such a system is important in the facilitation of international trade. In this paper, the advance ruling systems for tariff classification in the European Union (EU), China and Taiwan will be compared. It is shown that the advance ruling systems for tariff classification in these three jurisdictions all emphasise the efficiency of customs administration more than the legitimate expectation and procedural rights of the applicants. This imbalance might result from the complicated nature of tariff classification; however, it can also make the advance ruling system less attractive for international traders to use.
在许多司法管辖区,国际贸易商可以在进口或出口货物之前向海关当局申请关税分类的预先裁定。关税分类预先裁定制度将为国际贸易商提供更多的法律确定性,因为他们可以与海关当局沟通,并提前获得具有法律约束力的关税分类决定。这种制度对促进国际贸易很重要。本文将对欧盟、中国大陆和台湾的关税分类预先裁决制度进行比较。研究表明,这三个司法管辖区的关税分类预先裁决制度都强调海关管理的效率,而不是申请人的合法期望和程序权利。这种不平衡可能是由于关税分类的复杂性造成的;然而,这也可能降低预先裁决系统对国际交易者的吸引力。

Managing security in global supply chains has been gaining increasing attention in business and governmental agendas since the terrorist attacks in the United States in 2001. Since then several new voluntary government-business partnership programs have emerged to enhance security in end-to-end supply chains. However, a few programs have existed for a longer time, one of them is the BASC (Business Alliance for Secure Commerce) program, active as a business alliance in Latin America since 1996, originally fi ghting narcotics smuggling, and later converted into a holistic supply chain security management program. Understanding the implications – costs, tradeoffs, benefi ts, etc. – of security management programs is a complicated task, with very limited existing literature. This paper, being the fi rst survey of its kind, presents the results of the survey carried out with 102 BASC member companies, including: (1) the most commonly implemented security measures; (2) the most (and least) efficient security measures; (3) the relationship between the cost and effectiveness of the measures; and (4) the benefi ts obtained while implementing these security measures. Finally, the paper provides recommendations for governmental and company decision makers on designing future ‘win-win’ supply chain security programs.
自2001年美国发生恐怖袭击以来,全球供应链的安全管理越来越受到企业和政府议程的关注。从那时起,出现了几个新的自愿政府-企业合作项目,以加强端到端供应链的安全性。然而,一些项目已经存在了很长时间,其中之一是BASC(安全商业商业联盟)项目,自1996年以来作为拉丁美洲的商业联盟活跃,最初是打击毒品走私,后来转变为整体供应链安全管理项目。理解安全管理程序的含义——成本、权衡、收益等——是一项复杂的任务,现有文献非常有限。本文是首个此类调查,介绍了对102家BASC成员公司进行的调查结果,包括:(1)最常用的安全措施;(2)最(和最)有效的安全措施;(三)措施成本与效果的关系;(四)实施这些安全措施所获得的效益。最后,本文为政府和公司决策者提供了设计未来“双赢”供应链安全方案的建议。
