Time-Series Wage Differential in Taiwan: The Role of International Trade

Rising relative wages between skilled and unskilled workers in developed countries has been a popular subject of recent studies. This paper analyzes Taiwan, a semi-developed economy, where the relative wage reveals a declining trend since the mid-1980s. The authors study the role of international trade. A major point of departure is to distinguish the effects of net exports to OECD countries from those to non-OECD countries. The paper also differentiates the effects of net exports to China from those to non-OECD countries except China. It is found that net exports to the OECD countries raise the relative wage of skilled workers, whereas net exports to non-OECD countries and China diminish the relative wage. Moreover, the impacts of net exports to China are much larger than those to OECD and other non-OECD countries. The documented wage effects of international trade in this work diverge from what existing works have argued based on Heckscher–Ohlin theory.     

人民币汇率对我国对外贸易结构的影响分析

作者利用贸易特定化系数衡量了我国2005年7月21日人民币汇率形成机制改革之后的对外贸易结构，结果显示随着人民币汇率的爬行式缓慢升值，我国大部分资源密集型商品的净出口减少，劳动密集型商品和资本、技术密集型商品的净出口增加，竞争力增强，进出口商品的贸易结构得到优化。因此，进一步完善人民币汇率形成机制，推动人民币汇率稳步升值对我国进出口商品贸易结构是长期利好的。     

Do oil price changes really matter to the trade balance? Evidence from Korea-ASEAN commodity trade data

The contribution of this article is to assess the effect of oil prices have on the trade balance in the framework of bilateral commodity trade data between Korea and each of the four ASEAN member countries—Indonesia, Malaysia, Singapore, and Thailand. To examine this subject thoroughly, we first assume the effects of oil price changes to be symmetric and apply the linear autoregressive distributed lag (ARDL) method to the subject. We find that the price of crude oil indeed has an important role in affecting Korea's trade balance with those four ASEAN economies in both the long- and short-run. We then separate oil price hikes from oil price plunges and implement the nonlinear ARDL method to reveal that there is evidence that changes in oil prices appear to have asymmetric effects on the trade balance for certain products in the long- and short-run.     

Does the role of observer countries in the regional trade agreement matter for intra-regional trade ?

This article investigates the effects of trade by observed economies on the intra-regional trade by South Asian Association for Regional Cooperation (SAARC) members using Poison pseudo maximum likelihood estimator (PPML) gravity models with panel data over the period 2008–2014. Eight SAARC members and eight observed countries, including the EU, are analysed in capturing the trade effect of observed economies on intra-regional trade in SAARC. This article provides an empirical measure of observers’ trade, FDI and Official development assistance (ODA) with SAARC if the exports and imports of observers to/from SAARC have positive or negative signs for intra-regional exports and imports. The results show that the exports and imports of observers to SAARC members have positive effects on bilateral exports among the members. The FDI of observers reduces the bilateral intra-imports in SAARC and ODA also has a negative effect on bilateral exports among the members. These results imply that the imports by SAARC members from observer countries increase intra-regional trade in the region. The FDI and ODA increase and decrease intra-regional trade in SAARC, respectively, implying that the policies for both FDI inflow from observers and efficient aid management are needed to increase regional welfare. The study also recommends that trade between SAARC members and its observers help to increase intra-regional trade in SAARC.     

Trading Goods or Human Capital: The Gains and Losses from Economic Integration

In this paper, I quantify the economic consequences of liberalizing migration in the OECD and compare them with those of a hypothetical liberalization of trade across the OECD. First, I investigate the bilateral migration and trade agreements between the EU and Australia, Canada, Japan, Turkey, and the US. Second, I show that the overall impact of reducing all legal restrictions on migration in the OECD is moderate (1.6 percent in real GDP), while the gains from removing tariff and non‐tariff barriers to trade among all of the OECD economies are slightly lower (1.1 percent in real GDP). Finally, both the theoretical and numerical findings suggest that the direction of relationships between trade and migration (either substitutability or complementarity) depends on the type of shock imposed in the system.     

International Economies of Scale and the Gains from Trade

In this paper, we present a two-country trade model with external economies of scale that emerge on an international level but are partially localized in each country. First, we show that the larger country exports the good produced in an industry with external economies of scale in the trading equilibrium. Second, we investigate the welfare effects of trade for the following two cases: (I) the case where external economies are completely localized in autarky; (II) the case where external economies are internationally effective in autarky. In case (II), it is shown that trade can be welfare-decreasing for both countries.     

Removing export-credit subsidies to the Soviet bloc: Who gets hurt and by how much

Estimates of Soviet Bloc import elasticities and of the value of credit subsidies on loans to the bloc in 1981 are used in order to simulate the impact on OECD exports, if these subsidies had been eliminated in that year. The elasticity estimates indicate that price changes have little bearing on hard currency spent on a particular commodity by the Soviet Bloc. If subsidies had been eliminated in 1981, the total decline in OECD exports to the Bloc would have been less than 5%, and for any country, if proportionally distributed among suppliers, no more than 6%, no less than 2%.     

A comparative analysis of the impact of oil prices on oil-rich emerging economies in the Pacific Rim

This paper examines the relationship between raw materials prices and economic growth through two channels, the terms of trade (ToT) and energy efficiency (EF), in three emerging Pacific Rim economies, Russia, Indonesia and Malaysia. We demonstrate positive relationships between changes in output and oil prices and between changes in GDP and energy efficiency (EF). We examine the impact of oil prices on output growth through the ToT and EF channels. The effect of oil prices on ToT in Russia and Malaysia is positive but negative in Indonesia. Oil prices have a positive effect on EF in all three countries.     

人民币升值对农产品进出口影响的实证分析

人民币升值直接影响的是农产品的进出口贸易价格,不一定会显著影响农产品的进出口贸易额。利用偏自相关函数(PACF)和互相关函数(CCF)方法进行实证分析,我们可以看到:(1)人民币缓慢的升值速度给进出口商提供了充足的调整时间;(2)我国进出口农产品的价格弹性比较低,勉强超过ML条件的临界值;(3)由农业生产资源禀赋决定的农产品贸易格局很难改变;(4)人民币升值预期对农产品贸易产生的正向促进作用对冲了实际升值的滞后负面影响。由于这些原因,人民币的缓慢升值并没有对我国农产品贸易产生明显的冲击。     

A model of trade and growth for the developing world

This paper describes structure, assumptions and projection results of the SIMLINK model. The purpose of this modelistosimulate the trade linkages between the developed and developing world. By taking the growth expectations of the OECD countries and the price of petroleum as a starting point, the model estimates the price and volume of a series of commodities important in LDC exports. The export earnings for seven LDC regions are estimated from the commodity projections, and combined with a predetermined estimate of capital inflows to calculate import capacity. A simple growth model for each region then determines the import constrained growth rate for that region.     

Commodity Prices and the Dynamics of Inflation in Commodity‐Exporting Nations: Evidence from Australia and Canada*

A commodity‐price boom is under way. What does this boom mean for inflation in countries with substantial net commodity exports? The answer depends on movements in commodity prices, changes in foreign exchange rates and the determinants of domestic price inflation. We estimate equations to provide indications of the strength of each of these forces for both Australia and Canada. The results show that world commodity prices move pro‐cyclically with world industrial production and that rates of change in commodity prices are directly related to domestic inflation in both countries. However, there is an offsetting impact of exchange‐rate changes, which is strong enough in the case of Australia, but not Canada, to substantially eliminate the inflationary impact of a commodity‐price boom.     

Export and import composition as determinants of bilateral trade in goods: evidence from Russia

Conventional theory and several empirical studies state that incomes and exchange rates are the key determinants of the trade balance. Here, we argue that export and import composition are also key explanatory variables because some goods are inelastic and/or with a high added value, directly and indirectly affecting income and price elasticities and trade balance. Thus, if exports and/or imports significantly consist of price inelastic products, then, a positive and a negative effect, respectively, should be expected on the trade balance. Using bilateral trade data and dynamic panel models, we found that the ratio of exports of crude petroleum and natural gas (price inelastic goods) to total exports is significantly and positively associated with the Russian trade balance in goods. For its part, Russian imports of high-tech goods (income elastic and price inelastic with a high added value) show a negative association. The goods balance of Russia also responded to changes in relative income, but there is only weak evidence of reactions to changes in the exchange rate. These findings partially explain the persistent surplus in the Russian trade balance and current account.     

Metrics capturing the degree to which individual economies are globalized

We discuss metrics of globalization for individual economies as distance measures between fully integrated and trade restricted equilibria in economies initially operating under less than full integration with the global economy. Such metrics can be used to construct country globalization metrics reflecting the distance of economies from full global integration due to trade barriers, barriers to factor flows, barriers to international financial intermediation, solved technological diffusion and other economy-specific features yielding less than full integration into the global economy. Many distance metrics present themselves and none are wholly satisfactory since they each behave differently across various displacements from integration. Distance measures can, for instance, be small in goods space but large in price space. We present alternative measures constructed for eight OECD economies and comment in a concluding section on other measures used elsewhere in the literature such as trade/GDP ratios.     

South African trade policy mattersTrade performance and trade policy*

South African trade policy has exerted a major influence on the composition and aggregate growth of trade. In the Apartheid period, South Africa developed a comparative advantage in capital‐intensive primary and manufactured commodities partly because of its natural resource endowments, but also because the pattern of protection was particularly detrimental to exports of non‐commodity manufactured goods. By contrast, trade liberalization from 1990 not only increased imports, but by reducing both input costs and the relative profitability of domestic sales also boosted exports. This evidence suggests that additional trade liberalization and policies that afford South African firms access to inputs at world prices could well be part of the strategy to enhance export diversification.     

Exchange Rate Volatility,Earnings Uncertainty and Bidirectional Trade Flows: Empirical Evidence on Ghana

Although the empirical findings on the impact of exchange rate volatility on trade is diverse, the growing consensus in the literature appears to suggest that for developing economies, the theoretically expected negative relationship almost always exists. The paper takes a different approach to empirically assess this relationship by analysing the impact of exchange rate volatility independently on total trade, imports and exports. The intuition behind this approach is to assess exactly how exporters and importers are incentivised (differently or similarly) by exchange rate volatility costs. Whereas adequately risk-aversed Ghanaian exporters in the presence of higher exchange rate volatility and the absence of hedging facilities effectively compensated against exchange rate risk by increasing volume of exports, import decisions were to some extent (although not effectively) negatively affected by exchange rate volatility. The different responses by Ghanaian exporters and importers to higher exchange rate volatility costs are reflected in the relationship between volatility and total trade. The useful policy lessons and the challenges that the empirical evidence present are discussed.     

The convergence in domestic value-added of exports in the EU

Difficulties in measuring domestic value-added in exports (DVA) have led to the development of alternative measures of trade in value-added terms. These new measures have enabled more accurate estimates that reveal that the EU countries from Central and Eastern Europe (CEE10) exhibit an approximately five percentage points lower DVA share of exports compared with other EU countries (EU15). The lag is on average the highest in knowledge-intensive manufacturing sectors (eight percentage points) and the lowest in knowledge-intensive services (0.3 percentage points). However, this article argues that the CEE10 economies have acquired new knowledge by participating in GVCs and thus have gradually started increasing their level of DVA. Based on EU trade data, this article presents evidence of convergence of DVA in manufacturing and especially in the services sector. It is also shown that a negative relationship exists between participation in GVCs and DVA in the CEE10 economies that is declining over time in both manufacturing and services exports.     

The determinants of service exports from Central and Eastern Europe

The transition economies of Central and Eastern Europe (CEE) have become important exporters of many types of services to Western Europe. We identify the sources of CEE’s advantages over competing exporters, such as India, China and Brazil, using disaggregated data on service exports and a novel estimation technique for the gravity equation. Our results indicate that the importance of geographical distance varies substantially across types of service exports. Geography is important for exports of construction services, but it has a negligible impact on computer‐related services. However, the relative quality of legal institutions influences trade across a broad range of service categories. The results demonstrate that aggregating services that are not homogeneous could conceal important differences in the effects of geographical distance and other variables on the pattern of service trade.     

Habit persistence and the structure of international commodity trade

The paper analyzes the commodity structure of exports and imports of nine industrialized countries, using a dynamic version of the Linear Expenditure System. The hypothesis implied by this approach is that the structure of commodity trade can be explained by a combination of habit persistence and constant marginal expenditure shares. Application of the model to the trade composition of nine countries shows that there are considerable differences in the strength of habit persistence across countries and across commodity groups as well as between exports and imports. These are crucial for the explanation of the associated expenditure and price elasticities.     

The trade impact of European Union agricultural preferences

We assess the impact on agricultural trade of European Union (EU) trade policies, using a gravity model based on disaggregated trade flows from 161 developing countries (DCs) to 15 EU member countries. We use a sample selection framework to account for potential selection bias of positive trade flows and provide an explicit measure for relative preference margins. From a policy perspective, our results debunk some of the most widespread criticisms of preferential policies: EU preferences matter and have a positive impact on DCs agricultural exports at both the extensive and intensive margins, although with significant differences across sectors.     

Adjustment costs and factor demands in Canadian manufacturing industries

This paper examines whether there is a relationship between the commodity terms of trade (the price of primary commodities relative to the price of manufactures) and the net barter terms of trade of 42 Sub-Saharan African countries. For most countries, there is little evidence of a stable, long-run relationship between the two terms of trade series. Accordingly, the practice in the literature of proxying for movements in any given country's terms of trade by using an aggregate index of relative commodity prices is inappropriate, and is likely to engender misleading policy conclusions.
