Business cycle co-movements between South Africa and the BRIC countries

This article examines the relationships between South African economy and the economies of the BRIC (Brazil, Russia, India and China). In particular, it identifies the nature and key features of the co-movement of South African business cycles with cycles of the BRIC countries. It uses the dynamic factor model to a set of 307 macroeconomic series during the period 1995Q2 to 2009Q4. We found significant evidence of synchronization between South Africa and the BRIC countries over the business cycle, although the magnitude of co-movement differs with each country. India portrays strong ties with South Africa over time. Moreover, Brazil, China and Russia lead South Africa in the long run, while India is contemporaneous. Further, the findings imply that the first two factors are BRICS factors while the third one is a US factor.     

EU Enlargement and Trade Integration: Lessons from a Gravity Model

The authors estimate gravity models using a large panel of bilateral trade flows across 61 countries between 1980 and 2003, which are applied as a benchmark for the integration of Central and South Eastern European countries with the euro area. They show that a careful examination of the fixed effects of the model is crucial for the proper interpretation of the results. The results suggest that trade integration between most new EU member states and the euro area is already relatively advanced, while the remaining Central and Eastern European countries have significant scope to strengthen trade links with the euro area.     

双边自由贸易协定深度异质性及区内全球价值链效应*——基于GVC修正引力模型实证研究

双边自由贸易协定深度嬗变,全球价值链引致贸易形成机制和形式变化,使得自由贸易区理论基础、影响机制和功能效应更替。本文基于对双边自由贸易协定深度演化以及相较于其他区域贸易协定的深度异质性研究,将公司产权理论纳入自由贸易区理论框架,形成双边自由贸易区内全球价值链效应的多维理论机制,并且运用适应全球价值链发展的修正引力模型和世界银行的贸易协定内容数据库对理论机制假设结论进行实证检验。研究发现：双边自由贸易协定总深度对区内成员国之间的全球价值链关联产生正向影响,相较于贸易相关条款深度而言,投资相关条款深度影响更大。此外,自由贸易区对象国差异性也会影响双边自由贸易区全球价值链效应的发挥。根据对象国不同选择差异化的自由贸易区深度在双边自由贸易区构建中重要性凸显。本文将为全球价值链背景下中国构建高标准自由贸易区网络的对象国选择、自由贸易区模式选择等提供政策参考。     

Gradual globalization and inequality between and within countries

Abstract.  This paper investigates the effects of gradual trade liberalization on intra‐country and inter‐country inequality. It assumes two countries, North and South, and two factors, skilled labour and unskilled labour. North is defined as the one that is relatively skilled‐labour abundant and larger. A marginal trade liberalization from autarky is shown to (a) increase (decrease) in skilled‐unskilled wage differential in the North (South) and (b) raise the inequality between North and South. As the global economy approaches free trade, a marginal trade liberalization has effects, which are the opposite of (a) and (b); that is, the relative wage falls in the North and rises in the South, and North‐South inequality decreases.     

Business-cycle synchronization in the EMU

This article asks whether the business cycles of the EU countries have become more or less synchronized after the introduction of the euro. Our findings show that all countries in our EU sample are better synchronized with the EMU-wide economy in the post-EMU period than they were before the euro. We also show that this increase in synchronization is present in all components of aggregate demand, as well as two supply-side variables, but it is more pronounced in the trade components (imports and, particularly, exports). It is also shown that the increase in trade within the EMU area is at least partly responsible for the increase in cyclical synchronization.     

The role of China in the world economy: evidence from a global VAR model

Since the 1980s, China has experienced very high economic growth, and its share in global trade has increased rapidly. Currently, however, the Chinese economy is rebalancing, and its growth is slowing. This paper investigates the spillover effects on other countries of a negative demand shock and negative stock price shock in the Chinese economy. We apply a global vector autoregressive model, which enables us to model international linkages between countries. Our results show that a one per cent negative China GDP shock reduces global growth by 0.22% in the short run. We find that GDP shock affects emerging economies more strongly than advanced economies. We also show that a stock price shock affects only emerging economies and does not affect advanced economies.     

Is the European integration speeding up the economic convergence process of the Central and South-Eastern European countries? A shock perspective

In the current context of continuous reassessment of the sustainability of the single currency and gradual enlargement of the euro area during the last decade, the objective of this research is to obtain new insights into the factors that determine the synchronisation of shocks in the Central and South-Eastern European countries vis-à-vis the euro area. The research contributes to the previous work by making a novel use of error correction model in a dynamic panel context which is extended by adding several important omitted variables related to the trade structure and policy coordination. We find that an increase in trade intensity, intra-industry trade and financial integration leads to less frequent asymmetric shocks. On the other hand, divergent fiscal policies are estimated in some model specifications to increase the shock divergence process, although the estimated impact is rather small to counteract the positive effects associated with trade and financial integration. The identified relationships in this research are affected by the significant trade and growth slowdown in the crisis period; while the global economic turmoil has boosted a demand shock convergence, its impact on the supply shocks is in the opposite (diverging) direction.     

Out of Africa? Locational determinants of South African cross-border mergers and acquisitions

South Africa is the Africa’s biggest source of outward foreign direct investment. This study examines the principal locational motives of cross-border mergers and acquisitions CBMA by South African firms for the 1990–2014 period. The role of inter-country cultural and economic linkages is also studied. Firm-level data of South African merger and acquisition activities in 74 host countries are used to estimate a number of model specifications that control for host-country economic, geographical, cultural and institutional characteristics. Estimations are carried out using random-effects negative binomial panel model. Capturing the host-economy market and enhancing efficiency are found to be the two major motives driving South African corporations’ CBMA activities. Natural resources acquisition seems a less important motive, while strategic assets such as patents and technology do not appear to be attractive. The role of cultural and economic linkages between the home and the host country is found to be substantial. South African firms prefer investing in Africa, particularly in countries bordering South Africa. In light of the study’s findings, South African CBMA activities can be compared with those from other emerging economies.     

中国对南非纺织业投资与贸易中的竞争与互补关系

中国＂走出去＂的产业和产品定位无意对发展中国家形成竞争关系,但作为新兴发展中经济大国,中国对外经贸活动不仅引起发展中国家的重视,也得到了发达国家的格外关注。非洲是中国南南合作的重点地区,中国低品质的投资和贸易对当地低端产品形成冲击,一方面影响中国形象,另一方面由于低端产品的附加值低,中方也得不偿失。相应的中国＂走出去＂战略应该调整投资和贸易结构,对发展中国家多输入资本密集型、高技术含量的产品和产业;避免对非洲国家的低端产品和就业产生竞争。本文以南非的纺织业市场为例,通过计算1990-2010年行业比较优势指数、边际行业内贸易指数等指标,详细分析了中-南经贸合作的竞争和互补关系,结论发现,中国在南非的纺织品投资和贸易活动有待进一步深化升级。为此,中国需要利用优势,吸收当地劳动力,放弃低端市场,占据高端市场,在竞争中促互补。     

Going global: differential accumulation and the great U-turn in South Africa and Israel

This paper offers a new theoretical approach for comparing the current political-economic U-turns in South Africa and Israel. Our principal focus is on a revised notion of capital, emphasizing the central role of differential accumulation by dominant capital groups. We further distinguish between an antagonistic “depth” regime in which differential accumulation is achieved via stagflation, and a less conflictual “breadth” regime where redistribution occurs through growth. Within this framework, we argue that both the recent transition in the two countries, as well as their former regimes, were greatly affected by global developments. Until the 1980s, accumulation in both countries depended largely on depth, characterized by a marked disparity between deepening crisis on the one hand, and rapid differential accumulation on the other. In South Africa, the large companies benefited disproportionately from the impact on gold profit of global inflation, and were therefore reluctant to abandon apartheid. Similarly, Israel’s leading firms recorded spectacular gains riding the global arms race and regional conflict, and hence voiced little opposition to the continuation of a war economy at home. Recently, however, these global forces went into reverse, triggering in both countries a shift from depth to breadth. The disinflation associated with rapid globalization undermined gold profit in South Africa, while the end of the Cold War pulled the rug from under the global arms race, drying up the flow of war profit in Israel. In these new conditions, dominant capital groups in the two countries can sustain their differential accumulation only by investing outside their own borders. Capital mobility, though, requires political-economic stability, hence the support of these groups for democracy in South Africa and to regional reconciliation in Israel.     

基于VAR模型的中欧贸易“J曲线效应”实证分析

欧元作为一种新兴世界货币既在全球经济中发挥日益重要的作用,也是人民币汇率形成机制中的重要权重货币,由于欧盟是中国最大的贸易伙伴,故欧元兑人民币实际汇率变动对中欧贸易平衡产生重要影响。本文采用1999—2008年间欧元兑人民币汇率数据和中国与欧元区贸易季度数据构建VAR模型,并运用单位根检验、协整检验和脉冲响应函数的分析方法对欧元汇率变动对中欧贸易相对差额的影响进行实证分析。结果表明,人民币兑欧元的贬值初期会引起中国对欧元区贸易收支的短期恶化,但经过一段时间后由于我国对欧元区出口数量增加,贸易盈余趋于稳定,中国对欧元区贸易存在汇率贬值的"J曲线效应"。     

Trade imbalances within the euro area and with respect to the rest of the world

Many studies have explored the determinants of current account balances in Europe. However, only in a few studies has trade balance been decomposed into intra balance, trade balance vis-à-vis the euro area, and extra balance, trade balance vis-à-vis the rest of the world. This decomposition is necessary for us to understand why some core euro area countries are acting as financial intermediaries for the periphery countries. Furthermore, the determinants of intra and extra balances might be different because nominal exchange rate cannot adjust between the EMU countries while their financial markets are highly integrated. Thus, we apply this decomposition and supplement the previous studies by including a larger set of theoretically plausible explanatory variables, which is derived from the current account literature. Our contribution is twofold: We observe that, contrary to Schmitz and von Hagen (2011), the introduction of a common currency has not increased the elasticity of net capital flows to per capita incomes within the euro area for the member countries. On the other hand, there is a great heterogeneity among the usual determinants of trade balances whether those contribute to intra balances or extra balances. These results increase our understanding of the imbalances in the euro area.     

International Trade and Manufacturing Employment: Is India following the Footsteps of Asia or Africa?

The Indian manufacturing sector has rapidly increased its integration with the world economy since the 1991 trade reforms. We examine whether trade integration created or destroyed jobs in the Indian manufacturing sector, and compare India's employment outcomes with four other countries—Bangladesh, Kenya, South Africa, and Vietnam. We find that the impact of international trade on manufacturing employment seems to be similar to those found for the two African countries rather than the two Asian countries, a surprising result for a country with an apparent comparative advantage in labor-intensive manufacturing goods, and a large excess supply of unskilled labor.     

Trade implications of the Euro in EMU countries: a panel gravity analysis

In this paper, we study the intra-EMU and intra-Eurozone trade effects of the euro adoption on 29 European Economic and Monetary Union countries (including 17 Eurozone economies and Iceland) from the period 1994 through 2011. We employ a generalized gravity model that controls for an extended set of trade theory and policy variables. The gravity model is estimated using the robust panel data techniques that includes times effects, besides country-specific effects. The various econometric specifications of the gravity equation, on the whole dataset of 29 economies, yield positive and significant impact (to be around 14 %) of the euro currency adoption on bilateral trade flows. Next, euro effect on bilateral trade and exports on a smaller dataset is estimated. The estimated results suggest that bilateral trade and exports increase by 20.81 and 18.57 %, respectively, when both the countries belong to the Eurozone. This effect is larger than the one obtained when only one of the two trading partners uses the euro as its currency. In addition, the validity of the assumptions of Heckscher–Ohlin (H–O) theory are checked for the countries under study. The estimated results reject the H–O theory in favor of Modern Trade theories. However, the low value of the coefficient on respective variable suggests that, over the period, the type of trade among these countries has transited from inter-industry trade to horizontal intra-industry trade. This suggests that these developed European economies are on the path of economic convergence via intra-industry trade.     

Economywide impacts of climate change on agriculture in Sub-Saharan Africa

Two possible adaptation scenarios to climate change for Sub-Saharan Africa are analyzed under the SRES B2 scenario. The first scenario doubles the irrigated area in Sub-Saharan Africa by 2050, compared to the baseline, but keeps total crop area constant. The second scenario increases both rainfed and irrigated crop yields by 25% for all Sub-Saharan African countries. The two adaptation scenarios are analyzed with IMPACT, a partial equilibrium agricultural sector model combined with a water simulation module, and with GTAP-W, a general equilibrium model including water resources. The methodology combines the advantages of a partial equilibrium approach, which considers detailed water-agriculture linkages, with a general equilibrium approach, which takes into account linkages between agriculture and nonagricultural sectors and includes a full treatment of factor markets. The efficacy of the two scenarios as adaptation measures to cope with climate change is discussed. Due to the limited initial irrigated area in the region, an increase in agricultural productivity achieves better outcomes than an expansion of irrigated area. Even though Sub-Saharan Africa is not a key contributor to global food production (rainfed, irrigated or total), both scenarios help lower world food prices, stimulating national and international food markets.     

Trade,Skill Biased Technical Change and Wage Inequality in South Africa

Trade openness influences the wage structure via technology adoption in middle income countries. Given the econometric challenges of handling endogenous trade and technology interaction, we offer an alternative quantification based on calibration of a general equilibrium model. We expand the standard open economy Ramsey model to include comparative advantage, technology adoption and skill bias influenced by investment decisions. The calibration constructs a reference path for South Africa and allows counterfactual analysis of trade openness. The quantitative results imply that trade effects via technology adoption and skill bias can be an important determinant of wage inequality in middle income countries.

Exchange market pressure,stock prices,and commodity prices in West Africa

As Africa continues its decade of rapid economic growth, the continent also faces the risk of becoming more susceptible to financial ‘contagion.’ Capital flows and trade linkages might cause one country’s currency market to influence those of its neighbors. Likewise, shocks to global commodity or asset markets might induce a crisis in one or more countries in the region. This study generates monthly measures of exchange market pressure (EMP) for four individual West African countries, as well as for the WAEMU franc zone, from 2002 to 2012. Vector Autoregressive (VAR) methods are then used to test for linkages among them, as well as to analyze the effects of various external price shocks. A number of spillovers are uncovered. More importantly, local connections dominate global ones in the case of stock- and commodity-price declines. Ghana, for example, is shown to be a ‘commodity currency’ when West African commodity prices are included in the VAR, but not when a global index is used.     

International portfolio reallocation: Diversification benefits and European monetary union

We investigate the determinants of bilateral international equity and bond portfolio reallocation across a large cross-section of countries spanning over two sample periods: 1997-2001 and 1997-2005. We find that the strongest drivers are the marginal diversification benefits arising from the pure asset component and the initial degree of underweight. This evidence suggests that global portfolio reallocations over the asset boom and bust period were determined by optimal diversification considerations. We also find that due to economic and monetary union (EMU) the weight assigned by euro area investors to investment in euro area countries increased significantly in equity and fixed income portfolios, with a trade diverting effect against the British bond market.     

The transmission of business cyclesImplications for EMU enlargement1

We show that countries characterized by large bilateral trade and financial flows tend to have more correlated business cycles. However, we also find that countries with divergent fiscal policies and highly regulated labour markets are subject to idiosyncratic cycles. Applying these results to the new member states of the EU weakens the optimistic view towards the monetary integration of these countries into the euro area, which is frequently found in the literature. Although our results suggest that extensive trade and financial linkages are likely to result in further increases in business cycle correlation, an increase in labour market regulation and the pursuit of national fiscal policies may result in a counteracting effect.
