International financial integration and real exchange rate long-run dynamics in emerging countries: Some panel evidence

The aim of this article is to provide new empirical evidence on the impact of international financial integration on the long-run Real Exchange Rate (RER) in 39 developing countries belonging to three different geographical regions (Latin America, Asia and MENA). It covers the period 1979–2004, and carries out ‘second-generation’ tests for non-stationary panels. Several factors, including international financial integration, are shown to drive the long-run RER in emerging countries. It is found that the new financial environment characterised by international financial integration leads to a depreciation of the RER in the long run. Further, RER misalignments take the form of an under-valuation in most MENA countries and an over-valuation in most Latin American and Asian countries.     

How do trade and financial integration affect the relationship between growth and volatility?

The influential work of Ramey and Ramey [Ramey, G., Ramey, V.A., 1995. Cross-country evidence on the link between volatility and growth. American Economic Review 85, 1138-1151 (December).] highlighted an empirical relationship that has now come to be regarded as conventional wisdom—that output volatility and growth are negatively correlated. We reexamine this relationship in the context of globalization—a term typically used to describe the phenomenon of growing international trade and financial integration that has intensified since the mid-1980s. Using a comprehensive new data set, we document that, while the basic negative association between growth and volatility has been preserved during the 1990s, both trade and financial integration significantly weaken this negative relationship. Specifically, we find that, in a regression of growth on volatility and other controls, the estimated coefficient on the interaction between volatility and trade integration is significantly positive. We find a similar, although less robust, result for the interaction of financial integration with volatility.     

Stock return dynamics,option volume,and the information content of implied volatility

This article reports new empirical results on the information content of implied volatility, with respect to modeling and forecasting the volatility of individual firm returns. The 50 firms with the highest option volume on the Chicago Board Options Exchange between 1988 and 1995 are examined. First, the results indicate that the ability of implied volatility to subsume all relevant information about conditional variance depends on option trading volume. For the most active options in the sample, implied volatility reliably outperforms GARCH and subsumes all information in return shocks beyond the first lag. For these active options, implied volatility performs substantially better than indicated by the prior results of Lamoureux and Lastrapes ( 1993 ), despite significant methodological improvements in the time‐series volatility models in this study including the use of high‐frequency intraday return shocks. For the lower option‐volume firms in the sample, the performance of implied volatility deteriorates relative to time‐series volatility models. Finally, compared to a time‐series approach, the implied volatility of equity index options provides reliable incremental information about future firm‐level volatility. © 2003 Wiley Periodicals, Inc.

International capital flows,returns and world financial integration

International capital flows have increased dramatically since the 1980s, with much of the increase being due to trade in equity and bond markets. Such developments are often attributed to the increased integration of world financial markets. We present a model that allows us to examine how greater integration in world financial markets affects the behavior of international capital flows and financial returns. Our model predicts that international capital flows are large (in absolute value) and very volatile during the early stages of financial integration when international asset trading is concentrated in bonds. As integration progresses and households gain access to world equity markets, the size and volatility of international bond flows decline. This is the natural outcome of greater risk sharing facilitated by increased integration. This pattern is consistent with declining volatility observed during 1975–2007 period in the G-7 countries. We also find that the equilibrium flows in bonds and stocks predicted by the model are larger than their empirical counterparts, and are largely driven by variations in equity risk premia. The model also predicts that volatility of equity and bond returns decline with integration, again consistent with the data for G-7 economies.

Stock index futures markets: stochastic volatility models and smiles

This study examined whether the inclusion of an appropriate stochastic volatility that captures key distributional and volatility facets of stock index futures is sufficient to explain implied volatility smiles for options on these markets. I considered two variants of stochastic volatility models related to Heston (1993). These models are differentiated by alternative normal or nonnormal processes driving log‐price increments. For four stock index futures markets examined, models including a negatively correlated stochastic volatility process with nonnormal price innovations performed best within the total sample period and for subperiods. Using these optimal stochastic volatility models, I determined the prices of European options. When comparing simulated and actual options prices for these markets, I found substantial differences. This suggests that the inclusion of a stochastic volatility process consistent with the objective process alone is insufficient to explain the existence of smiles. © 2001 John Wiley & Sons, Inc.

The economic value of volatility transmission between the stock and bond markets

This study has two main objectives. Firstly, volatility transmission between stocks and bonds in European markets is studied using the two most important financial assets in these fields: the DJ Euro Stoxx 50 index futures contract and the Euro Bund futures contract. Secondly, a trading rule for the major European futures contracts is designed. This rule can be applied to different markets and assets to analyze the economic significance of volatility spillovers observed between them. The results indicate that volatility spillovers take place in both directions and that the stock‐bond trading rule offers very profitable returns after transaction costs. These results have important implications for portfolio management and asset allocation. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:1066–1094, 2008     

Return and volatility transmission between China's and international crude oil futures markets: A first look

We examine return and volatility transmission between the newly established crude oil futures in China and international major crude oil futures markets using intraday data. For the first time, we document evidence for cointegration relationships among these oil futures markets. Both China's and Oman's oil futures markets react to deviations from their long-run equilibrium with West Texas Intermediate and Brent oil futures. There is also new evidence for asymmetric volatilities and correlations across these oil futures markets. Furthermore, the Chinese oil futures have stronger linkages with the international major futures markets than Oman futures.     

开发性金融在推动周边金融合作中的战略选择:中国与东南亚国家双边的视角

东盟有两类国家对开发性金融存在需求:(1)老挝、缅甸、柬埔寨;(2)越南、马亚西亚、菲律宾等。前者虽与中国友好,但宏观环境不利于企业投资;后一类国家投资环境较好,但也面临一些特定的发展问题,且同时与中国在南海问题上存在分歧。我们提出建立准经济飞地的模式,使中国的开发性金融参与到周边金融合作当中。其中,第一类国家适用于经济特区模式。该模式有利于为中国企业的投资创造较好的小环境。对第二类国家,中国的首选策略是分化,菲律宾是可能的突破口;开发性金融的介入也应以此为考虑。从经济角度看,可借鉴新加坡"主题园区模式";从政治角度看,园区主题的选择要体现分化策略,使之与其他东盟国家构成竞争关系,以达到示范和分化的效果。     

International briefing 18: training and development in Vietnam

Vietnam provides a typical case of an emerging economy, which has attempted to develop the country and join the world economic mainstream with a highly agricultural base, large and young labour force, and a dynamically growing private sector. After a long period of quantitative growth, it is now focusing on achieving quality of development, with a view to balance economic growth and quality of life improvement for its population. Education has been chosen to be the key plank in the successful implementation of this strategy. This article reviews the general socio‐economic background of the country, the high need for skilled labour, the structure of its educational system, the pitfalls at the high education level, and its strategy to overhaul the whole system in order to ensure quality from the input phase of the development process.     

Financial development,sectoral reallocation,and volatility: International evidence

This paper studies how financial development affects the volatility of GDP growth through the channel of sectoral reallocation. For 28 OECD countries over the period 1970–2007, we construct a benchmark industrial portfolio that minimizes the economy's long-term volatility for a given level of long-term labor productivity growth. We find that financial development substantially increases the speed with which the observed industrial composition of output converges toward the benchmark. To overcome endogeneity concerns, we exploit sectoral sensitivities to financial deepening and exogenous liberalization events.     

Terms-of-trade shocks and macroeconomic volatility in developing countries: panel smooth transition regression models

This paper investigates the relationship between terms-of-trade shocks and macroeconomic volatility for a panel of 58 developing countries from 1980 to 2015. Using a Panel Smooth Transition Regression model, we prove first, that terms-of-trade volatility have a statistically significant and positive impact on the volatility of output growth, although the magnitude of this effect is not the same by the report to the threshold that has been identified. Second, the terms-of-trade volatility affect macroeconomic fluctuation differently depending on whether the country is a net exporter of the commodity, fuel or manufactured goods.     

International trade in durable goods: Understanding volatility, cyclicality, and elasticities

Data for OECD countries document: 1. imports and exports are about three times as volatile as GDP; 2. imports and exports are pro-cyclical, and positively correlated with each other; 3. net exports are counter-cyclical. Standard models fail to replicate the behavior of imports and exports, though they can match net exports relatively well. Inspired by the fact that a large fraction of international trade is in durable goods, we propose a two-country two-sector model in which durable goods are traded across countries. Our model can match the business cycle statistics on the volatility and comovement of the imports and exports relatively well. The model is able to match many dimensions of the data, which suggests that trade in durable goods may be an important element in open-economy macro models.     

EU integration of transition countries: Overlap of requisites and remaining tasks

Transition and reorientation towards Western Europe have been the two decisive challenges for the Central and Eastern European countries (CEECs) since 1989. Whereas in the early 1990s the transition from the central planning system to a market economy was the main goal of economic policies, the requirements for closer integration with the Western European countries have since then increasingly gained in importance. How do the two processes overlap? What requirements remain to be met before the candidate countries can join the European Union?     

Institutional Ownership and Future Stock Returns: An International Perspective

We investigate the risk‐adjusted performance of the aggregate equity holdings and trades of 13,807 active mutual funds located in 16 countries between 2001 and 2014. Using portfolio sorts, we find weak evidence that institutional holdings exhibit positive subsequent risk‐adjusted returns. However, any outperformance is unlikely to stem from short‐term informational advantage: stocks bought do not outperform stocks sold in the subsequent quarter. This finding is robust to regressions of subsequent stock returns on changes in institutional ownership and holds for different measurements of institutional trading.     

Stock Price Informativeness and Corporate Governance: An International Study

This study investigates the cross‐country relationship between firm‐level corporate governance and stock price informativeness. Using firm‐level data from 22 developed countries, we find that stock price informativeness, as measured by firm‐specific stock return variation and future earnings response coefficients, increases with the quality of a firm's corporate governance. Further analyses show that all mechanisms except board‐related governance relate positively to stock price informativeness. Finally, firm‐level corporate governance plays a more significant role in strengthening the stock return–earnings associations for firms in countries with strong institutional environments. This evidence highlights the role of country‐level legal investor protections in shaping the relationship between firm‐level corporate governance and stock price informativeness.     

Stock market development and economic growth: Evidence from seven sub-Sahara African countries

The paper examines the long run and causal relationship between stock market development and economic growth for seven countries in sub-Saharan Africa. Using the autoregressive distributed lag (ARDL) bounds test, the study finds that the stock market development is cointegrated with economic growth in Egypt and South Africa. Moreover, this test suggests that stock market development has a significant positive long run impact on economic growth. Granger causality test based on vector error correction model (VECM) further shows that stock market development Granger causes economic growth in Egypt and South Africa. However, Granger causality in the context of VAR shows evidence of bidirectional relationship between stock market development and economic growth for Cote D’Ivoire, Kenya, Morocco and Zimbabwe. In Nigeria, there is a weak evidence of growth-led finance using market size as indicator of stock market development. Based on these results, the paper argues that stock markets could help promote growth in Africa. However, to achieve this goal, African stock markets need to be further developed through appropriate regulatory and macroeconomic policies.
