基于CGE模型定量分析国际贸易绿色壁垒对我国经济的影响——以发达国家对我国出口品征收碳关税为例

美、欧发达国家为促进本国绿色产业发展,以"碳关税"为突破口,在国际贸易中试图设置绿色壁垒。本文以剖析碳关税的潜在影响为例,建立了国际贸易壁垒对我国经济影响的系统分析框架,并利用动态可计算一般均衡模型(SIC-GE)定量测算了各方面经济影响。结果表明,碳关税对我国实体经济的影响要小于对名义价格水平的影响;对高耗能产品出口抑制作用明显,而对高附加值产品出口影响很小,甚至会有刺激作用。

FTA,Exchange rate pass‐through and export price behavior – Lessons from the Australian dairy sector

The growing number of bilateral and regional free trade agreements (FTAs) alongside exchange rate volatility has raised a question on whether these affect exporters’ pricing behaviors, hence competitiveness. This study contributes to this topic by examining Australian dairy export price behavior across eight major markets taking into account the extent of pass‐through of exchange rate and tariff as well as FTAs between Australia and its trading partners. Commodity‐level dairy trade data from 1996 to 2016 and the feasible generalized least squares methods are employed. The study finds incomplete pass‐through at the industry level. The dairy export prices decrease by 1.7% if Australian dollar depreciates by 10%, while 10% tariff reduction is associated with 0.7% export price cut. Results at the commodity level show different pricing behaviors across destination and commodity markets. Overall, apart from the tariff effects, there is minimal evidence of the impacts of FTAs on dairy export prices.     

Market Integration and Market Efficiency under Seasonal Tariff Rate Quotas

Switzerland applies seasonal tariff rate quotas (TRQs) for the import of many fruits and vegetables during the domestic harvest season. We examine how this system affects the relationship between Italian and Swiss tomato prices and test for physical market integration and spatial equilibrium conditions over time. We use detailed, transaction‐based data on trade flows and trade costs and estimate an extended parity bounds model, following Barrett and Li (2002). We confirm that in the summer season, when TRQs are in place, markets are inefficient. While quota holders receive positive rents, the marginal rents for importers without quota shares are negative. This inhibits trade flows above the in‐quota import quantity allowed by TRQs. Hence, despite leading to inefficiencies and creating rents for importers, seasonal TRQs are effective in protecting domestic production against competing imports.

Tariff quota administration in China's grain markets: An empirical assessment

In 2016, the U.S. launched a trade dispute against China at the World Trade Organization, arguing that China has been restricting its grain imports via tariff quota administration. Despite sharp criticisms by the U.S., the extent to which the grain imports were restricted in China remains largely unknown, primarily due to that China's grain import behaviors are still under-researched. The U.S. grain export sector might actually gain little from China's grain trade liberalization in the short run, since China has become less import dependent on the U.S. through the pursuit of import diversification. In this context, this article aims to quantify impacts of the tariff quota administration on China's grain imports from its trading partners. We calculate ad valorem tariff equivalents of the tariff quota administration and then estimate import demand elasticities using a source differentiated import demand model. We find that the tariff quota administration might have reduced China's quota fill rates for the grain commodities by 10–35% during 2013–2017. In particular, the U.S. wheat exports to China were largely negatively affected. We also find that the tariff quota administration in China acts like a variable import levy—its import restrictiveness varies negatively with world prices, leading to lower import demand elasticities.     

碳关税征收对双边贸易的预期影响——基于中美两个碳经济大国的微观分析方法

文章用微观经济分析方法,基于中美两个碳经济大国的视角分析了碳关税的征收对双边贸易的预期影响。分析结果为:美国征收碳关税,短期内会由于美国进口需求减少和其他不被施加碳关税国家的价格优势导致中国出口量下降;长期中出口商需要提高价格来补偿技术投入的支出,国际价格上涨将进一步导致需求降低,贸易量减少;同时碳关税征收将导致出口国贸易条件恶化,社会福利损失;而进口国可能由于贸易条件的改善在短期内获得收益。     

The Liberalisation of Tariff Rate Quotas under Oligopolistic Competition

Several proposals for liberalising agricultural tariff rate quotas (TRQs) have been proposed within the WTO Doha Development Round. The literature suggests that the effectiveness of liberalisation depends upon which of the three elements of a TRQ constrains imports. Most contributions assume perfect competition. This article uses an oligopoly two‐stage capacity constrained model, in which the mode of competition is endogenous, to investigate the impact of different liberalisation options of TRQs, that is, the reduction in the in‐quota and out‐of‐quota tariffs and the expansion of the quota. This article shows that consideration of the nature of competition between traders may provide unconventional conclusions about the effectiveness of the various TRQ liberalisation options; furthermore, the article shows how an increase in the number of rivals, under certain circumstances, may be more effective in increasing trade than reducing tariffs.

Detecting origin fraud with trade data: the case of U.S. honey imports*

Following the 2001 U.S. imposition of antidumping tariffs on imported honey from China and Argentina, industry press noted patterns of trade suggesting that honey was being transshipped to circumvent tariffs, origin fraud that was later uncovered in criminal cases. This article presents three approaches that use trade and production data to flag countries for possible instances of origin fraud and then compares these countries with those implicated in criminal cases and media reports. In our preferred empirical method, we also find that countries with higher corruption scores are more likely to show increases in suspicious trade patterns following the tariffs.
