Measuring the Economic Costs and Benefits of the EU

The EU has pursued protectionist policies not merely in food but also in manufacturing at the customs union level. In services it has not dismantled much of the existing national protectionism. The economic costs are calculated here at some 3% of GDP for the UK and some 2% for the rest of the EU. Added to its social interventionism, these costs suggest that the EU has put political integration before economic efficiency. This paper draws heavily on my book with Vidya Mahambare and Eric Nowell (Minford et al., 2005). I am grateful for helpful comments to Kim Huynh, Michele Fratianni and other participants at the IU 2006 conference in Fratianni’s honour. I contributed this paper in recognition of many pleasurable discussions with Michele over the years on this and many other topics. JEL Classification Numbers: F13, F14     

论适度保护关税税率

面对日益加速的经济全球化进程,各国仍然在普遍使用关税措施来保护本国产业的发展.在这方面,发展中国家需要解决的问题是设定一个适度的保护关税税率,以让国内产业既有生存和发展的空间,同时又有足够的竞争压力来提高效率.根据国内与国际平均生产成本的差异来确定保护关税的税率是一个可行的办法.进一步削减关税是我国加入WTO后需要承担的义务,应当按照适度保护关税的原则把平均关税的税率稳定在一个合理的水平上,并根据国内不同产业的发展状况,提供必要而有效的保护.     

Real Versus Tariff Liberalization: A Welfare Comparison Under Monopolistic Competition

A distinction between real trade costs (e.g., administration, border formalities, transport costs) and tariff costs is introduced into a standard monopolistic competition trade model. Driven by the number of firms, welfare under real trade barriers turns out to be lower than under an equivalent tariff barrier. Based on this finding, the paper shows that integration or rather liberalization measures (generating a certain increase in world trade) that reduce real trade barriers generate a larger welfare gain than integration consisting of a reduction in tariffs.     

我国关税调整对广东经济贸易的影响分析

2011年以来,我国对进口关税进行了一系列新的结构性调整。这是我国外贸政策调整和转变的一次具体表现,从我国外贸战略角度看,贸易平衡发展和转型升级是当前我国外贸发展面,晦的紧迫任务。本文收集近年我国关税调整方案及其对广东经济贸易的影响,首先是对近年来我国关税调整政策内容进行了归纳和总结,提炼了关税调整政策的指导思想和主要特征,进而分析了这一系列调整对广东的经济特别是对外贸易增长和发展转型所造成的影响,最后从政府和企业两个层面提供了政策建议。     

Beyond the flat rate bias: The flexibility effect in tariff choice

Flat rates are a prominent pricing scheme for telecommunications services and are often preferred by consumers although average costs would be lower in an alternative usage-based tariff. Reasons are that flat rates protect against unexpectedly high costs (insurance effect), are more likely to be chosen if actual usage is overestimated (overestimation effect), and prevent any disutility that is associated with the immediate perception of marginal costs (taximeter effect). This study complements the literature on tariff biases by highlighting that a lack of tariff flexibility is a major impediment to choosing a flat rate: empirical support for this flexibility effect is found, while, at the same time, the insurance and overestimation effect that run in favor of flat rates are confirmed. Finally, the managerial implications of the findings for the introduction of the new cost cap tariff are discussed. The hybrid cost cap tariff can combine the flexibility and the insurance property, and may, therefore, exert a cost cap bias on consumers.

On estimating Armington elasticities for Japan's meat imports

By fully accounting for the distinct tariff regimes levied on imported meat, we estimate substitution elasticities of Japan's two-stage import aggregation functions for beef, chicken and pork. Although the regression analysis crucially depends on the price that consumers face, the post-tariff price of imported meat depends not only on ad valorem duties but also on tariff rate quotas and gate price system regimes. The effective tariff rate is consequently evaluated by utilising monthly transaction data. To address potential endogeneity problems, we apply exchange rates that we believe to be independent of the demand shocks for imported meat. The panel nature of the data allows us to retrieve the first-stage aggregates via time dummy variables, free of demand shocks, to be used as part of the explanatory variable and as an instrument in the second-stage regression.     

Impact of Donald Trump’s tariff increase against Chinese imports on global economy: Global Trade Analysis Project (GTAP) model

Donald Trump’s presidential campaign contains several trade protectionism plans. This paper aims to analyze possible global impact of United States’ plan to impose import tariff increase against China. The GTAP model is implemented. The simulations present possible short-run effects of full-protection and manufacturing-only protection with appropriate retaliation response from China. The policy might lead to GDP, terms-of-trade, and welfare decline in United States and China; and an increase in trade balance for United States. Trade diversion pattern is observed in the simulation results, predicting shrinking bilateral trade between the two countries and increasing export toward their third trading partners.     

Water pricing reform analysis: alternative scenarios

This paper compares alternative transition paths to efficient water pricing. The analysis is based on representative agent model, where two sources of water supply exist: exhaustible groundwater stock and a renewable substitute. Two alternative water pricing reforms are considered: gradual tariff increase and multipart pricing with first block sold at the initial pre-reform tariff and additional water sold at higher prices (block pricing reform). Under block pricing reform, the amount of water offered at low price gradually diminishes. The results of comparative analysis prove that under the same reform time horizon block pricing is preferred to the gradual tariff increase.     

Modelling New Zealand dairy products: evidence on export survival and duration

This article presents evidence concerning the pattern of New Zealand dairy exports duration and survival from 1989 to 2017. It also analyses the influence of a set of supply, demand and gravity‐type drivers on the hazard rate for New Zealand dairy export relationships. The findings are summarised as follows. First, New Zealand dairy export relationships are dynamic with numerous entries and exits to and from foreign markets. Around half of the relationships survived for only 1–2 years at the sequence level. Second, duration of sequence, left‐censoring, initial export, decomposed sequences, New Zealand export price index, the number of cows available for dairy production, the number of origins and destinations, and destination partner’s GDP are the most significant factors reducing the hazard rate of export relationships. As regards the effects of the non‐tariff measures, it is interesting that technical barriers of trade are found to significantly decrease the hazard rate. Only pre‐shipment inspection and contingent trade protective measures are significant impediments to New Zealand dairy export relationships. Finally, hazard probabilities for New Zealand dairy export relationships are estimated to be ‘L‐shaped’ over time, whether or not non‐tariff measures are applied to New Zealand dairy products.
