Tariffs and privatization policy in a bilateral trade with corporate social responsibility

Corporate social responsibility (CSR) has become a global business strategy and thus it provides significant welfare implications for designing optimal policies. This paper investigates the impact of CSR on policy interaction between tariffs and privatization in an international bilateral trade model. We find that CSR is closely related to the government's policy decisions on tariffs. In particular, we find that the strategic tariff for increasing domestic welfare is always higher (lower) than the efficient tariff for improving global welfare when the degree of CSR is low (high). We also show that a privatization policy raises tariff and worsens (improves) domestic welfare when the degree of CSR is low (high). Finally, we demonstrate that both countries choose a nationalization policy even though the privatization policy is globally optimal when the degree of CSR is high.     

Trade liberalization and markups: Micro evidence from China

This paper presents evidence from highly disaggregated Chinese firm-product data that, given productivity, input tariff reductions induce an incumbent importer/exporter to increase product markups. We further investigate empirically the mechanisms underlying this trade liberalization effect, and find that input tariff reductions decrease marginal costs, and their effects on markup adjustments are more profound among firms with higher import dependence. Moreover, we exploit unique features of Chinese data by comparing results for two trade regimes: ordinary trade (wherein firms pay import tariffs to import) and processing trade (wherein firms are not subject to import tariffs). While the aforementioned trade liberalization effects and mechanisms only apply to ordinary trade, processing trade samples are used in a placebo test. The paper also shows that more productive firms charge higher markups for products. All these findings are robust to alternative markup measures including one estimate using physical-quantity output data, different production function specifications, a subsample consisting only of pure exporters, and estimations based on our theoretical derivations.     

Reducing tariff evasion: The role of trade facilitation

Can simplifying customs procedures reduce tariff evasion? We measure tariff evasion as the mis-representation of import values in response to increasing tariffs. In a dataset covering 121 countries and the whole set of HS6 product categories in 2012, 2015, and 2017, we show that simplifying border procedures, that is trade facilitation, reduces tariff evasion. Holding tariff rate constant at its mean, improving a country’s overall trade facilitation performance from the 25th percentile to the median reduces tariff evasion by almost 20%. The moderating effect is especially due to improving the pre-shipment legal certainty of customs procedures. Among the potential mechanisms, improving trade facilitation performance is effective in reducing tariff evasion due to under-reporting of import prices, as well as in countries with weaker control of corruption. The results suggest that countries can gradually implement trade facilitation reforms to cost-effectively minimize tariff evasion.     

Regional Blocs and Foreign Direct Investment

The paper examines the impact of the emergence of regional blocs on the patterns of interbloc and intrabloc trade when firms have the option to engage in foreign direct investment (FDI). For exogenously given external tariffs, when firms have the option to engage in FDI, all interbloc trade may cease—complete trade diversion that is replaced by interbloc FDI investment creation. In such an event the volume of world trade declines but this is more than offset by the increase in world output due to direct investment. The paper also investigates the optimal tariff that a trading bloc levies on imports from nonmember countries. The tariffs are restricted by the option to engage in two‐way direct investment; hence, the regional blocs are hampered from mutually harming one another through an escalation in the tariff war. Finally, the formation of two regional blocs enhances the welfare of all countries.     

Reconciling Observed Tariffs and the Median Voter Model

Median voter theory applied to trade policy predicts positive tariffs in capital‐abundant countries and negative tariffs in labor‐abundant countries. Negative tariffs are rare, and this paper reconciles the median voter theory with observed protectionism across countries. By considering large countries, I show the optimal tariff is a sum of the median voter component and a positive term of trade component. Positive terms of trade effects raise tariffs in all countries, and can overcome the negative median voter component in labor‐abundant countries. Testing the tariff prediction with cross‐section and panel data from the 1990s, I show the median voter component is negative in labor‐abundant countries and positive in capital‐abundant countries. As expected, terms of trade effects raise tariffs across all countries and are stronger among nonmembers of the WTO.     

Revenue-Constrained Combination of an Optimal Tariff and Duty Drawback

A duty drawback is an export subsidy determined as a percentage of the tariffs paid on the imported inputs used in its production. This paper examines the revenue-constrained optimal tariff structure in a small open economy including a duty drawback as a trade policy tool. This paper has two main aims. First, we show that the revenue-constrained optimal combination of tariff and duty drawback for a given revenue level is not unique. Second, we show that if the optimal import tariff rates are all positive when the duty drawback rate is zero, then the optimal import tariff rates are always positive when the duty drawback is positive.     

加工贸易、企业生产率和关税减免-来自中国产品面的证据

本文研究两个问题:一是不断深化的进口关税减免对我国企业生产率提升有何影响,二是企业参与加工贸易能否有助于促进企业生产率的提升。一方面,最终产品的进口关税减免强化了企业间在本土市场的竞争,从而有助于提高生产率;另一方面,企业参与加工贸易能得到额外的贸易所得,从而促进企业生产率的增长。通过采用2000—2006年间我国外贸产品的海关数据和规模以上制造业企业生产方面的大型微观数据,本文构建了各企业所面临的关税税率,并精确计算出企业的全要素生产率。基准回归结果显示,关税下降10%,企业生产率会上升大约3%—6%。更重要的是,在考虑企业间由所有权造成的差异性后,发现加工贸易企业相对于非加工贸易企业有更高的生产率。     

The United States is a Small Country in World Trade*

Despite being the largest country in world trade and thus presumably having high optimal tariffs, the United States has long had low and declining levels of protection. This paradox suggests that the United States is failing to exploit its monopsony power by levying optimal tariffs. Using data on world output and trade flows, we find that the United States is a small country in world trade in that its trade policies have negligible impacts on world prices. In the median manufacturing industry, US tariffs reduce world prices by only 0.12%. United States optimal tariffs are also typically small (3.6% in the median industry) and are lower than existing US tariffs in most industries. It is no puzzle that the United States has been a champion of free trade since the 1930s—the United States, like other small countries, benefits economically from tariff reductions.     

Tariffs and non-tariff barriers to trade in Hungary: The impact of the Uruguay Round and EU accession

International trade has featured prominently in Hungary's rapid transition to a market economy. This paper reports some relatively simple summary and complementary indicators for tariffs and non-tariff barriers (NTBs) to trade, which are designed to reflect the level and structure of tariffs and the scope of NTBs in Hungary. The existence of tariff 'spikes' and highly pervasive NTBs in certain sectors constitutes prima facie evidence that the domestic dead-weight efficiency and net welfare losses caused by tariff and non-tariff protection as well as the costs to consumers could be high. The indicators are used to highlight several key developments associated with Hungary's transition to a market economy, implementation of the Uruguay Round (UR) agreements and possible accession to the EU.     

Fortress Europe: Jericho or Château d’If?

Traditional analysis of customs union formation suggests that it leads to an increase in members' external tariffs. This paper stresses two aspects of European trade and trade policy—a large volume of intra-industry trade between similar countries and a political motivation for tariffs—and highlights a role for tariff coordination in a model of differentiated products in which tariffs affect domestic costs and thus export prices and the magnitude of monopolistic rents. We show that when workers choose the tariffs and receive but a small portion of tariff revenues, the union's tariff wall falls.     

Trade Liberalization in the Presence of Foreign Direct Investment and Tax Credits: Estimates for Costa Rica

The paper uses a calibrated general-equilibrium model to quantify the welfare impact of trade liberalization—and compute the optimal tariff structure—for Costa Rica when trade-policy-induced foreign direct investment and international capital taxation with credits are present. It shows that complete trade liberalization reduces Costa Rica's welfare, as it leads to an outflow of capital and loss of tax revenue which more than offset the efficiency gains from an enhanced resource allocation. The optimal tariff structure for the Costa Rican economy turns out to be a mixture of relatively small import tariffs and subsidies.     

Industrial labour productivities and tariffs in South Africa

The analysis of the effect of tariffs for labour productivity faces the challenge of tariff policy endogeneity. Tariff policy is designed to promote economic development and the industrial sector tariff structure may reflect characteristics of the industries protected. We seek to identify the effect of tariffs by taking advantage of multilateral tariff liberalization using reductions in industrial sector tariffs in other world regions as instruments for sectoral tariff reductions in South Africa. The data cover 28 manufacturing sectors over the period 1988–2003. We find that tariff reductions have stimulated labour productivity when instrumented by multilateral tariffs. The ordinary least‐squares estimates show downward bias and this confirms the endogeneity of tariffs. Investigation of channels of effects shows some support for the importance of competitive pressure and technology spillover from trade liberalization.     

Tariffs,Quotas, and Forward Contracts under Asymmetric Information*

We consider optimal trade policy for a large country with private information. We show that the optimal tariff leads to a signaling equilibrium with higher tariffs and lower welfare than under complete information, whereas the optimal import quota replicates the complete information equilibrium and thus is superior to the tariff. We also show that, with the tariff, the country may be better off being uninformed. Finally, we show that if the importing nation cannot commit to its tariff, the use of futures contracts together with the dynamically consistent tariff leads to the same equilibrium as under complete information with commitment.     

Optimal Tariffs with Endogenous Production Location

This paper attempts to examine how the inclusion of economic space affects trade policies and to make a comparison between optimal tariffs with endogenous location and those with exogenous location. In particular, it is shown that the output effect of a tariff change with endogenous location is greater than that with exogenous location if the production function is non-CRS. Moreover, when the production function is CRS (resp. not CRS), the optimal tariff under endogenous location is the same as (lower than) the one under exogenous location.     

Strategic tariffs, tariff jumping, and heterogeneous firms

The majority of research to date investigating strategic tariffs in the presence of multinationals finds a knife-edge result where, in equilibrium, all foreign firms are either multinationals or exporters. Utilizing a model of heterogeneous firms, we find equilibria in which both pure exporters and multinationals coexist. We utilize this model to study the case of endogenously chosen tariffs. As is standard, Nash equilibrium tariffs are higher than the socially optimal tariffs. Unlike existing models with homogeneous firms, we find that non-cooperative tariffs promote the existence of low-productivity firms relative to the socially optimal tariffs. This highlights a new source of inefficiency from tariff competition not found in models of homogeneous firms. In addition, we find that in many cases the Nash equilibrium tariff when FDI is a potential firm structure is lower than when it is not. As a result, FDI improves welfare by mitigating tariff competition.     

中美贸易协商:不确定性与最优选择

本文试图为中美贸易协商提供一个理论框架,并从更一般化的意义上对削减关税之谜(tariff reduction paradox)给出了一个新的理论解释:从一个高关税的初始环境出发,在一定条件下政府之间会相互协商以降低关税,但不会完全取消关税。这是由于在某些情况下,关税可以减少多重瓦尔拉斯均衡带来的不确定性。进一步而言,通过外商直接投资发生的"禀赋互换(endowment swaps)"可成为优于关税和贸易管制的一种替代选择。     

Optimal Tariff Policy on Imports from Multinationals*

Using partial equilibrium analysis, it is shown that for small countries there is an optimal tariff on imports from a monopolistic multinational. There is also (under specified circumstances) a tariff at which the multinational finds subsidiary production more profitable than exports: the switchover tariff. The interaction between the optimal and switchover tariffs is analyzed from the small country's welfare standpoint. The conclusion is that there is not one, but a variety of possible optimal policies for the country: trade at the optimal tariff, with or without prohibition of subsidiary production, or tariff-protected subsidiary production.     

Price Discrimination by a Many-Product Firm

Determining the optimal selling strategy for a multiproduct firm facing consumers with unobservable tastes is a difficult task. This paper aims to show how almost optimal nonlinear tariffs can often be found when the number of products is large. Moreover, such tariffs take a simple form: (i) when taste parameters are independently distributed across products, the almost optimal tariff is a single cost-based two-part tariff which can extract virtually all consumer surplus; (ii) when tastes are correlated across products, perhaps because of income differences across consumers, the almost optimal tariff can be implemented as a menu of two-part tariffs each of which has prices proportional to marginal costs.     

全球价值链影响下的中国关税水平*——来自中国制造业的证据

本文基于中国政治经济背景,构建了一个关税影响因素理论模型,且利用2005—2011年中国制造业134个部门的数据,通过OLS和Tobit方法进行了经验验证。结果表明：（1）外国最终产品中的中国增加值越高,或者中国最终产品中的外国增加值越高,则中国对于该产品的关税水平越低;（2）贸易协定的签署不仅会直接降低中国的关税,还会扩大中国增加值上升对关税的负影响,削弱外国增加值上升对关税的负影响。
