The Buffer Stock Model Redux? An Analysis of the Dynamics of Foreign Reserve Accumulation

Cointegration analysis suggests that the buffer stock precautionary model accounts for the optimal reserve demand in nine developing countries located in Asia and Latin America. The corresponding VECMs are further interpolated, using the permanent and transitory innovation decomposition procedure, in order to assess the relative impact of the time series on the convergence to equilibrium after a shock. Finally the (asymmetric) effect on the speed of convergence of positive/negative changes in signal variables—such as the excess reserves of the previous period, relative competitiveness and US monetary stance—is found to be significant, in line with mercantilistic and fear of floating motives for hoarding reserves.     

Do Global Trade Distortions Still Harm Developing Country Farmers?

We estimate the impact of global merchandise trade distortions and services regulations on agricultural value added in various countries. Using the latest versions of the GTAP database and the GTAP-AGR model of the global economy, our results suggest real net farm incomes would rise in developing countries with a move to free trade, thereby alleviating rural poverty—despite a terms of trade deterioration for some developing countries that are net food importers or are enjoying preferential access to agricultural markets of high-income countries. We also show, for several large developing countries, the contribution of their own versus other countries’ trade policies. JEL no. C68, D58, F17, Q17     

Is devaluation expansionary or contractionary: Evidence based on vector autoregression with sign restrictions

The purpose of the paper is to examine the impact of real exchange rate changes – real devaluation or real depreciation – on outputs in 16 countries that fall within one of the three groups: Latin American countries, Asian countries, and non-G3 developed countries. For the first time in the contractionary devaluation literature, the analysis is based on a Vector Autoregression (VAR) model with sign restrictions method by Uhlig (2005) and Fry and Pagan (2011). The exchange rate shock is identified by imposing restrictions on the signs of impulse responses for a small subset of variables. The findings are as follows: (1) whether output increases after a real devaluation or not has little to do with whether the current account improves or not; (2) Latin American countries are quite homogenous in that the current account generally improves while output decreases after real devaluation; and (3) contractionary devaluation could happen in developed countries as well as in developing countries.     

Comments on S. Edwards: “Monetary unions, external shocks and economic performance: a Latin American perspective”

I discuss Sebastian Edwards’ most recent paper with great pleasure. As so much of the work of this distinguished economist, this paper provides new insights on a burning issue in international economics. Here Edwards provides empirical evidence on the resilience to external shocks of countries that lack a national currency (“monetary-union” or MU countries). The paper starts by reviewing the issues and literature relevant on exchange-rate regimes, dollarization, and MU in Latin America, with an emphasis on the question if countries in the region satisfy key optimal currency area criteria. Then the paper provides extensive new evidence on economic performance in MU countries, in comparison to countries with a national currency, using a large world panel sample. Performance tests are conducted for the comparative likelihood of MU countries of sudden stops in capital flows (SS) and large current (deficit) reversals (CAR), as well as their ability to absorb terms-of-trade shocks, SS, and CAR. The results are generally negative and significant for the comparative performance of MU countries. To set the stage, I start my comments by documenting first how country selection of exchange-rate and monetary regimes is quickly evolving in the world during the last decades, discussing subsequently how economists’ views follow suit (Section 1). Then I discuss some aspects of Edwards’ paper, focusing in particular on the data and model specification (Section 2). I end with brief implications for exchange-rate and monetary regime choice in Latin America.     

Trade adjustment in the WTO system: are more safeguards the answer?

For countries to engage successfully in the international tradingsystem, their industries, firms, and workers must respond continuallyto new conditions of competition. The continuing need to adjustarises both from policy changes approved in multilateral negotiations—e.g.implementation of trade liberalization commitments, preferenceerosion, or adverse terms-of-trade consequences of export subsidyelimination—and from ongoing changes in competitive pressuresinherent in a liberal trading system—e.g. effects on comparativeadvantage of changes in technology or factor supplies. But thepolitical response to a situation calling for adjustment isoften a call for ‘safeguards’—whether as anex ante provision in negotiated agreements or as an ex postmeasure once the agreement has been signed and the reality ofnew conditions takes shape. This paper examines the range ofadjustment problems confronting the current and future internationaltrading system, the economic arguments for intervention to dealwith these problems, the adjustment environment as set out inthe current World Trade Organization (WTO) Agreements, and proposalsfor reform. While the adjustment problems we discuss apply toboth rich and poor WTO member countries, we highlight the issuesof adjustment especially relevant for developing countries.     

Measuring Restrictiveness of Bilateral Trade Policies: A Comparison between Developed and Developing Countries

This paper compares the degree of openness to trade of three developed countries markets—the European Union, Japan, the United States—with that of three middle-income countries, namely Brazil, India, and China. A theoretically consistent protection measure—the Mercantilistic Trade Restrictiveness Index (MTRI)—is employed to average tariffs at different levels of aggregation. The computation relies on a comparative static applied general equilibrium model (Global Trade Analysis Project—GTAP) featuring imperfect competition as well as on the bilateral applied tariffs included in the most recent version of the GTAP database. Results provide a different picture from what could have been expected given the widely publicized diffusion of preferential schemes supposedly favoring developing countries exports.

Does China have an impact on foreign direct investment to Latin America?

We analyze empirically whether the emergence of China as a large recipient of FDI has affected the amount of FDI received by Latin American countries. Allowing for the structural break related to China's WTO accession, we found a significant negative impact of Chinese inward FDI on that of Mexico until 2001 and on that of Colombia after that date. The rest of Latin American countries do not seem to be affected by Chinese inward FDI. For the region as a whole, there is no significant Chinese effect on Latin America’s FDI.     

新兴发展中国家中TFP指标的适用性分析——基于模型的证明

全要素生产率(TFP)指标是衡量经济增长效率最常用的指标,本文回顾了关于全要素生产率(TFP)的相关争论。我们认为,基于完善市场经济条件下得到的TFP指标很难用来评价后发国家的经济增长质量。进一步,我们用技术进口模型和古诺竞争模型证明了在非均衡条件下,TFP指标可能低估了新兴发展中国家技术进步,而建立在投资基础上的经济增长策略是发展中国家不可逾越的一个阶段。     

Agricultural productivity growth in traditional and transitional economies in Asia

This paper reports estimates of agricultural productivity growth in Asian countries, with special attention to the transition economies. A parametric output distance function approach is formulated to decompose total factor productivity (TFP) growth into its associated components and to examine how input and output intensities shift in response to the adoption of innovations. The results show that by including the transition economies, Asia achieved healthy TFP growth at an annual average rate of 1.9 per cent. However, TFP growth and its components differ widely across the transition countries and at different stages of the transition periods within these countries.     

China's post-economic reform growth: The role of FDI and productivity progress

China has become the top FDI destination among all developing countries and remained host to the world's largest share of foreign direct investment receipts since its accession to the WTO in 2001. Given the impressive growth performance and FDI influx into China, the two globalized delta economies (GDEs), Pearl River Delta (PRD) and Yangtze River Delta (YRD), have continued to out-perform all other regions in China in terms of FDI absorption and growth. The role that inward FDI plays in the process of regional development and the exact channels through which economic growth would be affected are investigated by panel data estimations of the GDEs at the city level since China's economic opening and reform. This research shows consistent results with some recent findings in other developing countries in that FDI exerted spillover effects and affected productivity (TFP) growth of the recipients. While TFP was found to be increasing overtime in the GDEs cities and facilitated economic growth in both PRD/YRD regions, major technology- and knowledge-related factors including R&D and human capital other than FDI also played critical roles in TFP enhancement and regional growth. The endogeneity of TFP and the simultaneous relations of FDI in affecting TFP and output growth are also addressed in this regard.     

Inward and outward foreign direct investment and poverty: East Asia vs. Latin America

Using panel data of 12 middle-income countries in East Asia as well as Latin America, this paper examines how openness in general and outward FDI in particular affects poverty. While economic growth and trade openness are found to be associated with lower poverty, both outward and inward FDI adversely affect the mean income of the poorest quintile of the population. The results hold in both regions, though the Latin American countries seem to be in a somewhat less favorable situation.     

Cooperation among national drug manufacturers: Asociación Latinoamericana de Industrias Farmacéuticas (ALIFAR)

This article examines the background to the establishment of the Latin American Association of Pharmaceutical Industries (ALIFAR) and describes its activities and achievements. The national firms in Latin America lacked an institutionalized organization to present their collective viewpoints to governments and international organizations when they held important deliberations affecting the development of the pharmaceutical industry. Transnational corporations, on the other hand, were supported very effectively by a global organization. The creation of ALIFAR was, therefore, a logical and a strategical step in the fight for survival of the national firms in Latin America. Since its establishment in November 1980, ALIFAR has shown significant results and encouraging promise, which are described in the article and which may serve as useful guidelines for action in other developing countries.     

How do Chinese industries benefit from FDI spillovers?

Recently, Foreign Invested Enterprises (FIEs) in China have increased their investment in not only production activity but also R&D activity. This paper examines the impact of spillovers from such activities by FIEs on two types of innovations by Chinese domestic firms: Total Factor Productivity (TFP) and invention patent application, using comprehensive industry and province-level data. We evaluate such spillovers according to FIEs' ownership structure, the origin of foreign funds and whether they are from the same industry or from other industries. We find an interesting asymmetry between spillovers to TFP and invention patent applications; while we do not find significant intra-industry spillovers from FIEs but find robust inter-industries spillover related to TFP, we find substantial intra-industry spillovers promoting invention patent applications but no evidence of inter-industries spillovers. Furthermore, whereas spillovers from FIEs to Chinese firms' TFP stem from their production activities, the source of spillovers related to invention patent applications is mostly through their R&D activity. Our findings indicate a need for multidimensional evaluation of the role of FDI in developing countries.     

Slow Pass-through Around the World: A New Import for Developing Countries?

Developing countries traditionally experience pass-through of exchange rate changes that is greater and more rapid than high-income countries experience. This is true equally of the determination of prices of imported goods, prices of local competitors’ products, and the general CPI. But developing countries in the 1990s experienced a rapid downward trend in the degree of pass-through and speed of adjustment, more so than did high-income countries. As a consequence, slow and incomplete pass-through is no longer exclusively a luxury of industrial countries. Using a new data set—prices of eight narrowly defined brand commodities, observed in 76 countries—we find empirical support for some of the factors that have been hypothesized in the literature, but not for others. Significant determinants of the pass-through coefficient include per capita incomes, bilateral distance, tariffs, country size, wages, long-term inflation, and long-term exchange rate variability. Some of these factors changed during the 1990s. Part (and only part) of the downward trend in pass-through to imported goods prices, and in turn to competitors’ prices and the CPI, can be explained by changes in the monetary environment—including a fall in long-term inflation. Real wages work to reduce pass-through to competitors’ prices and the CPI, confirming the hypothesized role of distribution and retail costs in pricing to market. Rising distribution costs, due perhaps to the Balassa-Samuelson-Baumol effect, could contribute to the decline in the pass-through coefficient in some developing countries.     

From protectionism to free trade fever? Recent reforms in developing countries

During the 1980s, increasing numbers of developing countries unilaterally liberalized their trade regimes. This paper presents an overview of this dramatic shift from protectionism toward freer trade. South Asia, Latin America, and East Asia have implemented extensive reforms, yet each region has shown a distinct difference in approach and in the degree of liberalization actually achieved. Latin America stands out as moving sharply toward the level of openness of the East Asian Newly Industrialized Countries (NICs). Only in Africa is there little progress toward freer trade.     

Competition among developing countries for foreign investment in the eighties — Whom did OECD investors prefer?

Conclusions Developing countries including the NIEs failed to maintain their shares in total foreign investment of all major OECD countries in the eighties. Shares were generally lower by 1988 than ten years ago. This negative trend can be observed for investment in manufacturing in particular, but also for non-manufacturing. Middle East and SubSaharan African countries came down to negligible shares, while shifts in shares mainly occurred between Latin America as a losing region and the Asian NIEs as winners. In absolute terms, however, Latin America remained a major host area. Within the regions, trends towards concentrating investment on few countries proliferated from Latin America where such concentration was traditionally high, to Asia with Singapore, Malaysia, Indonesia, and partly Hong Kong, in the lead. Against this background, home countries widely continued to maintain their traditionally preferred strongholds as did Japan in Southeast Asia, West Germany in Brazil and Argentina, the US in Latin America in general, and the UK in Commonwealth countries. Such patterns remained stable over time, but differed from each other.     

Fixed Exchange Rates and Disinflation in Emerging Markets: How Large Is the Effect?

We examine developing countries which have institutional quality ratings for the effects of exchange rate rigidity on inflation. The level of institutional development exerts no effect on the impact of currency regimes. However, the interaction of institutional quality and exchange rates has, in the most plausible specifications, a negative impact on inflation. This suggests that fixed exchange rates exert at most a contingent effect on inflation, and indicates that countries in Eastern Europe and Latin America contemplating currency pegs would be better off improving institutional quality prior to adopting the euro or dollar and expecting a large subsequent disinflationary effect.

The New Economy in Europe, 1992-2001

Despite the fast catching up in the diffusion of informationand communication technologies (ICT) experienced by most EUcountries in the last few years, information technologies haveso far delivered few productivity gains in Europe. In the secondhalf of the past decade, the growth contributions from ICT capitalrose in six EU countries only (the UK, Denmark, Finland, Sweden,Ireland, and Greece). Unlike in the USA, this has not generallybeen associated with higher labour or total factor productivity(TFP) growth rates, the only exceptions being Ireland and Greece.Particularly worrying, the large countries in Continental Europe(Germany, France, Italy, and Spain) showed stagnating or mildlydeclining growth contributions from ICT capital, together withdefinite declines in TFP growth compared to the first half ofthe 1990s. It looks as though the celebrated ‘Solow paradox’on the lack of correlation between ICT investment and productivitygrowth has fled the USA and come to Europe.     

Synergies and competition: Export survival in Africa and Latin America

Using firm-level export data from six African (Burkina Faso and Senegal) and Latin American (Guatemala, Mexico, Peru, and Uruguay) countries, we examine factors that determine the survival of export flows. We explore the effects on export survival of changes in the number of home-country exporters serving the same destination, firm-level export diversification, and country-level factors. Unlike previous studies, we find that export survival rates decrease with the number of co-exporters selling the same product to the same country. We also find that the relationship between firm-level product diversification and export flow survival is hump-shaped: firms that do not diversify or are highly diversified have lower survival of product-destination flows. Our findings are robust to various alternative specifications. The main findings hold across both regions and all countries. However, the number of co-exporters negatively affects survival in Africa more than in Latin America.
