Preference Erosion,Government Revenues and Non‐tariff Trade Barriers

Developing countries benefiting from developed country unilateral trade preferences fear that Doha Round tariff cuts will erode the value of those preferences. That these programmes confer significant benefits, however, is not clear. Studies indicate that the impact of preference erosion would be minimal for most developing countries. But for a small subset of middle‐income and least‐developed countries, concern may be warranted. WTO members, should address affected countries’ concerns, perhaps by tailoring WTO tariff negotiations to lessen adjustment pressures and providing development assistance. Developing countries also are anxious that lower tariffs will reduce government revenues. Dependence on tariff revenue is diminishing and trade liberalisation need not result in lower total tax revenues or even lower customs revenues. Much depends on a country's current tariff and trade regime, its tax structure and its overall economic structure. At some point, a country does need to broaden its tax base and look to other revenue sources to offset declining tariff revenues. Tax reform, therefore, complements trade reform. A third area of developing country concern is non‐tariff barriers (NTBs), which may limit market access even after tariffs are reduced. Despite prior WTO work in this area, NTBs remain a thorny issue for all WTO members.     

Trade openness,tax reform and tax revenue in developing countries

This article investigates empirically whether the effect of tax reform (involving the progressive replacement of trade tax revenue with domestic tax revenue) in developing countries' tax revenue performance (measured by tax revenue‐to‐GDP ratio) depends on the degree of trade openness of these countries. The analysis has used an unbalanced panel data set of 95 developing countries over the period 1981–2015 and the two‐system GMM approach. Results suggest that tax reform is positively and significantly associated with tax revenue performance in developing countries, with the magnitude of this positive effect increasing as countries experience a higher development level. Additionally, and more importantly, countries that further open up their economies to international trade enjoy a higher positive effect of tax reform on tax revenue than countries that experience a lower degree of trade openness. Therefore, these findings should help dissipate the concerns of policymakers in developing countries that greater openness to international trade would further erode their tax revenue, including by lowering their international trade tax revenue. In fact, the implementation of an appropriate tax reform in the context of greater trade openness would generate higher tax revenue, while concurrently allowing countries to reap the well‐known benefits of international trade.     

The welfare impacts of a revenue-neutral switch from tariffs to VAT with intermediate inputs and a VAT threshold

The debate about replacing tariffs with value-added tax (VAT) in developing countries has paid little attention to the role of VAT as an input tax on the informal sector and has overlooked the usefulness of changing the VAT threshold in a revenue-neutral switch from tariffs to VAT. This paper contributes to the literature by addressing these two issues via a heterogeneous firm model of a small open economy with endogenous firm entry and VAT compliance. The results found indicate that the VAT collected on intermediate inputs consumed by the informal sector not only reduces the benefits of evading VAT, but also diminishes the production distortion between the formal and the informal sectors. The use of a change in the VAT threshold to offset lost tariff revenue leads to welfare gains; however, the source of such gains is different from that of a change in the VAT rate. While an increase in the VAT rate expands informality, a revenue-equivalent decrease in the VAT threshold reduces informality. These novel results suggest that the VAT threshold plays an important role in the design of revenue-neutral tax reforms.     

The impact of trade facilitation on poverty and inequality: Evidence from low- and middle-income countries

This paper using a trade model of imperfect competition and product differentiation, examines the welfare effects of two popular tariff-tax reforms: (i) a tariff cut combined with an equal increase in the consumption tax and (ii) a tariff cut combined with an increase in the consumption tax that leaves the consumer price of the imported good unchanged. It is shown that if tax revenues are lump-sum distributed and firms compete over prices, then coordinated tariff-tax reforms improve welfare for a low degree of product differentiation, whereas these reforms are welfare-reducing for any degree of product differentiation under Cournot competition. When, instead, revenues are used to finance the provision of public goods, then the total effect of these reforms on welfare depends, under plausible assumptions, on the strength of the consumer's valuation of the public good.     

Non-preferential trading clubs

This paper examines the welfare implications of non-discriminatory tariff reforms by a subset of countries, which we term a non-preferential trading club. We show that there exist coordinated tariff reforms, accompanied by appropriate income transfers between the member countries, that unambiguously increase the welfare of these countries while leaving the welfare of non-members unaltered. In terms of economic policy implications, our results show that there exist regional, MFN-consistent arrangements that lead to Pareto improvements in world welfare.     

Coordinating tariff reduction and domestic tax reform

A key obstacle to fundamental tariff reform in many countries is the revenue loss that it ultimately implies. This paper establishes and explores a simple and practicable strategy for realizing the efficiency gains from tariff reform without reducing public revenue, showing that for a small economy a cut in import duties (respectively, export taxes) combined with a point-for-point increase in domestic consumption taxes (production taxes) increases both welfare and public revenue. Increasingly stringent conditions are required, however, to ensure unambiguously beneficial outcomes from this reform strategy when allowance is made for such important features of reality as non-tradeable final goods and tradeable intermediate inputs.     

Would Freeing Up World Trade Reduce Poverty and Inequality? The Vexed Role of Agricultural Distortions

Trade policy reforms in recent decades have sharply reduced the distortions that were harming agriculture in developing countries, yet global trade in farm products continues to be far more distorted than trade in non‐farm goods. Those distortions reduce some forms of poverty and inequality but worsen others, so the net effects are unclear without empirical modelling. This article summarises a series of new economy‐wide global and national empirical studies that focus on the net effects of the remaining distortions to world merchandise trade on poverty and inequality globally and in various developing countries. The global Linkage model results suggest that removing those remaining distortions would reduce international inequality, largely by boosting net farm incomes and raising real wages for unskilled workers in developing countries, and would reduce the number of poor people worldwide by 3 per cent. The analysis based on the Global Trade Analysis Project model for a sample of 15 countries, and nine stand‐alone national case studies, all point to larger reductions in poverty, especially if only the non‐poor are subjected to increased income taxation to compensate for the loss of trade tax revenue.     

Welfare implications of trade liberalization and fiscal reform: A quantitative experiment

This paper studies the welfare implications of revenue-neutral trade liberalization and fiscal reform programs for developing economies using a multi-sector dynamic general equilibrium model of a small open economy. We analyze how different combinations of tariffs – on imported consumption goods, intermediate inputs, and capital goods – and taxes – on consumption, labor income and capital income – affect the transitional and long-run welfare. We report three main findings. First, trade liberalization programs financed by consumption and labor income taxes tend to result in substantial welfare gains, but financing the lost tariff revenue through capital income taxes can have an adverse impact on welfare. Second, a significant fraction of welfare changes is due to transitional effects stemming from the allocation of resources in response to changes in tariffs and taxes. Third, trade liberalization and fiscal reform programs often translate into much larger welfare gains in countries that are more open to international financial markets.     

Optimal tariffs,optimal taxes and economic development

Cross-section and time-series data suggest that nations substitute income taxes for tariffs as they develop. This paper confronts the data within the context of a two-country open-economy endogenous growth model in which public expenditure is financed by an optimal tariff and income tax. When the latter is subject to administrative costs, the model predicts that the government will optimally substitute the income tax for the tariff as output rises along the transition. The model is calibrated and a simulation yields time paths for the shares of total government revenue derived from the tariff and the income tax that are consistent with the data.     

Tax reforms in developing countries

Given the low level of tax revenue and the contradictory structure of tax legislation in many developing countries, there is broad agreement on the need for tax reforms in those countries. The following article reviews the problems associated with instituting such changes.     

Regional Trade Agreements versus Global Trade Liberalisation: Implications for a Small Island Developing State

This study undertakes an empirical investigation of the macroeconomic and sectoral impacts of two forms of regional trade agreements vis‐à‐vis global trade liberalisation on a small island country, using Fiji as a case study. In order to capture the feedback effects of such a complex set of policies, we employ a dynamic computable general equilibrium model of the Fijian economy to investigate (i) the impact of the Pacific Island Countries Trade Agreement (PICTA), (ii) the impact of PICTA, the Pacific Agreement for Closer Economic Relations (PACER), and the Economic Partnership Agreements (EPAs), (iii) the impact of full tariff liberalisation (i.e. tariff removal only), and (iv) the impact of full trade liberalisation, with removal of both tariff and non‐tariff barriers. While PICTA consistently provides the least benefits across a range of macroeconomic indicators including real output, welfare, trade volumes and employment, full trade liberalisation involving the removal of tariff and non‐tariff barriers provides the greatest benefits compared to the other scenarios in terms of real output. However, the latter scenario is outperformed by PICTA, PACER, the EPAs and full tariff liberalisation in terms of welfare effects, trade volumes and employment. The policy implications hold important lessons for developing countries considering trade liberalisation.     

Trade liberalization, product variety and growth in a small open economy: a quantitative assessment

We develop a numerical growth model that quantifies the welfare effects of trade liberalization. Additional intermediate input varieties provide the engine of growth and dramatically magnify the welfare gains from trade liberalization. In our central model, a 10% tariff cut leads to a 10.6% estimated gain in Hicksian EV. Systematic sensitivity analysis shows that there is virtually no chance of a welfare increase less than 3%, but a 6.6% chance of a welfare gain greater than 18%. We show that complementary reforms are crucial to fully realize the potential gains from the trade reform.     

Beyond Border Barriers: The Liberalisation of Services Trade in Tunisia and Egypt

Tunisia and Egypt have both recently undertaken significant steps toward trade reform. They have committed to a partnership agreement with the European Union. Both countries have also joined the WTO and are participating in Doha Round discussions on the liberalisation of non‐tariff barriers on both goods and services trade. These developments provide an interesting context within which to investigate not only the changes in welfare associated with reforms affecting the trade in goods, but also the impacts of services liberalisation. Using open‐economy computable general equilibrium models for both Tunisia and Egypt, this paper explores the reasons why structural differences in these two economies imply different opportunities and challenges with trade reform and services liberalisation. The gains from eliminating barriers at the border for goods trade are significantly greater for Tunisia than Egypt. Both countries, however, gain substantially from liberalisation of foreign direct investment in services. Furthermore, economic growth is more evenly distributed across sectors than with liberalisation of trade in goods alone. In addition to reporting on the impact of alternative policies on income, output, employment and trade, sector‐level effects are also considered.     

Trick or Treat? Development Opportunities and Challenges in the WTO Negotiations on Industrial Tariffs

Negotiations on industrial tariffs in the current WTO work programme have turned out to be surprisingly difficult. On the one hand, developing countries, particularly in Africa, are concerned about the potential negative effect on their industrial development of developed country efforts to push them into deep cuts in applied tariffs: after the disillusion of the Uruguay Round, promises of welfare gains seem unconvincing. On the other hand, a number of the more complex formula proposals for tariff‐cutting make it difficult for participants to evaluate what they have to do compared with what they hope to receive. The developing countries may achieve greater exports and welfare gains from the more ambitious proposals, but computations show that these also imply greater imports, lower tariff revenues, some labour market adjustments and reduced output in some politically sensitive sectors. Some way of assisting the developing countries in coping with these adjustments is required to take advantage of the opportunities presented by the negotiations.     

US–China rivalry: The macro policy choices

Stylised representations of recent US and Chinese tax reforms, tariffs against imports and alternative Chinese monetary targeting are examined using a calibrated global macro model that embodies both trade and financial interdependencies. For both countries, unilateral capital tax relief and bilateral tariffs are shown to be ‘beggar thy neighbor’ policies. As large economies, both enjoy ‘optimal tariffs’, even bilaterally, though net outcomes are shown to depend on the allocation of revenues. Bilateral tariffs are most advantageous for the US if the additional revenue finances indirect tax relief. Once US bilateral tariffs are imposed, China is a net loser irrespective of its policy response, though a currency float is shown to cushion the effects on its GDP in the short run. Equilibria in normal form non-cooperative tariff games have the US imposing tariffs while China liberalises.     

The economics of taxes with equivalent effects to tariffs

Developing countries are faced with the issue of tariff replacement at an early stage of their development, due to their increased commitments through Free Trade Arrangements with developed countries. As tariff replacement through VAT, or more sophisticated tools such as income tax, is neither practically nor economically desirable in these economies, this paper investigates the effects of an alternative replacement tax that only affects categories of goods not produced locally. This tax, denominated tax with equivalent effects to tariffs (TEET), is indeed a consumption tax as it concerns all goods, whether imported or potentially produced in the country. Based on a simple diagrammatic approach, the study shows that this tool tends to generate more welfare than tariffs if final prices of goods are left unchanged. It shows that a government can continue to maintain its revenues and increase the welfare of consumers through this fiscal replacement. Additionally, the political and economic reserves associated with this tool are discussed. The TEET are therefore useful mainly for small and non-diversified economies. It also remains that the use of this tool is, in practice, conditioned by the level of tolerance of developed countries, which tend to prohibit it in bilateral agreements with developing countries.     

数字经济国际税收改革:理论探源、方案评析与中国抉择北大核心CSSCI

数字经济国际税收改革是百年变局之际世界格局转换的焦点问题之一。数字经济加剧了全球化中的经济失衡,导致市场国征税权随之兴起,国际社会随之提出了税改的初步依据,但是仍需结合政府征税原理创新展开进一步探索。综观以经合组织双支柱为代表的市场国征税权改革方案,在数字经济居民国与市场国、政府征税与跨国公司避税、发达国家与发展中国家的复杂博弈中,“选择性”改革和复杂的规则设计展示了重大历史进步意义,但也凸显了欧美的妥协及其对既得利益的保护,同时更阻断了发展中国家对工业经济税基公平权的追溯,压制了落后地区和新兴行业启动经济的发展权。作为全球数字经济第二大国的中国,基于发展中社会主义市场经济的基本前提和税基安全、公平和发展的复杂目标,需要审慎参与反避税全球竞争与合作、全面协调数字经济与实体经济平衡、科学安排税收收入与经济成长的战略关系,才能在增强以中国为代表的发展中国家在税收和经济利益上的全面的、实质性公平权利的前提下,推动形成更加科学合理的国际税收秩序。     

Product-level estimation of import demand: Simulating the effects of tariff harmonisation

Developing countries have traditionally used import tariffs to protect infant industries and raise revenues to finance government expenditure plans. This approach, however, has tended to protect inefficient industries and to some extent hindered economic development. A disaggregated import demand model is estimated using monthly observations on 91 of the most frequently imported product items in Barbados. The results are then employed to evaluate the feasibility of harmonising tariff rates to some single rate across product categories. The results suggest that the estimation of aggregate import demand equations is not accepted by the data and therefore could result in misleading inferences. The policy simulation exercise indicates that a single applied tariff at the 30% level would essentially be revenue neutral, while rates above this level would lead to reductions in tax receipts.     

外国直接投资对我国税收贡献及影响的实证分析

在实证分析外国直接投资对我国各项税收总额及关税的定量贡献的基础上,采用行业分析的方法分析了外国直接投资对我国税收贡献的现状及存在的问题。本文认为虽然外国直接投资极大地促进了我国涉外税收、各项税收总额以及关税的增长,但给予其税收优惠也在一定程度上侵蚀了我国的税基,减少了税收收入。有必要分步骤地进行现有税收制度改革,最终统一内外资企业的税收制度。
