Regional Integration and Economic Growth

The rapid economic growth of developing countries that openedtheir markets to free international trade during the past twodecades has stimulated a large empirical and theoretical literatureon the impact of trade on growth. This literature concludesthat free trade and growth were positively correlated duringthe 1970s and 1980s. However, most studies focus on nondiscriminatoryopenness. Does regional integration matter for economic growth?Do regional trade agreements have any impact on growth? This article presents empirical evidence that countries withopen, large, and more developed neighboring economies grow fasterthan those with closed, smaller, and less developed neighboringeconomies. The results are robust to different specificationsof the empirical model and different definitions of openness,suggesting that small economies should grow faster when theyform regional trade agreements with large and more developedeconomies. However, testing for the impact of five regionaltrade agreements during the 1970s and 1980s finds that noneled to faster growth. The main reason seems to be that mostof these agreements were among small, closed, and developingeconomies.     

Cross-Border Mergers and Acquisitions and the Role of Free Trade Agreements

This article investigates the impact of the formation of free trade agreements (FTAs) on cross-border mergers and acquisitions (M&As). Using the comprehensive M&As dataset of Securities Data Company, we find that FTA relationship is associated with more bilateral cross-border M&As. Second, the cross-border M&As activities between a FTA country-pair do not increase faster than the acquiring country’s total foreign acquisitions, suggesting no evidence of investment diversion effect of FTA. Third, we find that existing FTA relationship with other countries positively affect cross-border M&As between a FTA country-pair. But these third-country FTA effects differ for acquiring country and target country when we look at the ratio of a country-pair’s FTA relative to the acquiring country’s total foreign M&As. Moreover, by exploring the detailed information on acquiring and target firms, we reveal that the effect of FTA differs for horizontal, vertical and conglomerate cross-border M&As. Our results are robust to various measures of M&As activities and econometric methods used.     

东盟自由贸易协定的基本特征、推动因素与前景展望

近年来,东盟积极参与自由贸易协定签署,已经成为亚洲地区重要的自由贸易协定中心之一。推动东盟积极参与自由贸易协定的因素,既有内部的经济一体化要求、大国均衡战略以及国际地位提升需要,也有主要发达国家东南亚战略变化的原因。东盟自由贸易协定格局的形成,一方面会削弱中国-东盟自由贸易区的经济效应,另一方面会对中国形成战略制约,积极调整我国的自由贸易协定战略势在必行。     

Southeastern European Trade Analysis: A Role for Endogenous CEFTA-2006?

The objective of this paper is to analyze the impact the Central European Free Trade Agreement of 2006 (CEFTA-2006) has had on trade and provide quantitative comparison with the original CEFTA and with trade liberalization under the EU integration process. The paper belongs to the strand of literature analyzing a free trade agreement in a gravity framework but treating the agreement as being potentially endogenous. The empirical evidence suggests that CEFTA-2006 exerted a positive, significant, and large effect on trade in Southeast Europe. This finding can be largely attributed to the distracted trade flows in the region over the 1990s. The effect of CEFTA-2006 has been estimated to be larger than the effect of the stabilization and association agreements. This counteracts the concern that the EU and the Southeastern European countries formed a "hub-and-spoke" structure in terms of trade.     

Short sales and speed of price adjustment: Evidence from the Hong Kong stock market

We present empirical evidence that short sales contribute to market efficiency by increasing the speed of price adjustment to not only private/public firm-specific information but also market-wide information. Shortable stocks are characterized by weaker trade continuity and stronger quote reversals. They adjust faster to new information than non-shortable counterparts. These findings remain robust even in an “up” market condition in which short sales are not binding. The amount of information incorporated in each trade is also significantly higher for shortable than non-shortable stocks in both “up” and “down” market conditions. After controlling for firm size, trading volume, liquidity, price and option trading, short sales stand out as one of the significant factors that speed up the price adjustment.     

信息传导与市场整合——基于商品期货上市的准自然实验

从制度设计上打破市场分割、促进市场整合,对提高市场效率、促进经济有序健康发展具有重要意义。本文以商品期货上市作为准自然实验,构建双重差分模型,实证检验了商品期货上市交易对现货商品市场价格整合的影响。研究发现,现货商品市场价格整合程度在相应商品期货上市后显著提升,这是因为商品期货上市显著地促进了价格信息在全国范围内的传导,且这种提升效应主要体现在价格信息传导比较顺畅的地区。此外,商品期货上市提高了现货商品市场价格同步性,缓解了现货商品价格信息滞后程度,降低了现货商品交易成本。进一步研究发现,商品期货市场的交易信息质量越高,越有利于提高现货商品市场的整合程度。本研究为当前我国建设全国统一大市场提供了一定参考。     

Sticky prices or economically-linked economies: The case of forecasting the Chinese stock market

We explore whether economic links via trade affect aggregate Chinese stock market returns. We find that market return indices from countries that China net imports from can forecast the Chinese aggregate market return at the weekly time horizon. The stock returns of countries that China net exports to have no consistently significant OOS predictability.The economic intuition for our results follows from the fact that China has positioned itself as a low-cost provider competing on price. As a low-cost provider China has a more difficult time passing cost increases through to export customers because of sticky prices. However, import costs, e.g., raw materials, are subject to both consumption and speculative demand and thus vary. We can conclude that costs will drive short term economic gains for the overall Chinese economy. One interpretation of our results is that supply shocks are absorbed within 2 weeks.     

Liquidity operations during the financial crisis 2008/09: evidence from the relations between Korean won onshore and offshore markets

This paper addresses the interrelation of onshore and offshore markets before and after the Bank of Korea intervened in 2008/09. During the financial crisis, Korea faced a liquidity crunch and leveraged its high level of reserves to conduct swap agreements in late 2008. To analyse how the reforms affected the mean and volatility spillover in between the spot and NDF markets, an extended GARCH model is used. The main findings of this paper are that prior to the financial crisis, the spot market dominated the offshore market. This changed after South Korea addressed the won’s liquidity crunch at the height of the crisis. Mean and volatility spillover between the markets diminished and the price gap narrowed. In addition to the empirical results, the paper also underlines the significance of liquidity and robust capital requirements for central banks.     

Equity market liberalization and corporate governance

Equity market liberalizations open up domestic stock markets to foreign investors. A puzzle in the literature is why developing countries exhibit relatively small financial impacts associated with liberalizations. We use cross-firm variation in corporate governance at the time of the official liberalization of the equity market in Korea to test whether governance can explain the extent to which firms benefit when countries liberalize. The results show that better-governed firms experience significantly greater stock price increases upon equity market liberalization. Following the liberalization in Korea, foreign ownership in firms with strong corporate governance was significantly higher than that in firms with weak governance. Better-governed firms also exhibit higher rates of physical capital accumulation after liberalization.     

The Determinants of Execution Costs in Short‐Term Money Markets

Prior research attributes the observed negative relation between execution costs and trade size in opaque markets to two factors—information asymmetry and broker‐client relationships. We provide evidence that a trader's ex ante transaction price information and the relationship traders have with their brokers are both significant determinants of a trader's execution costs in an opaque market; however, traders who establish strong relationships with their brokers will achieve a greater reduction in execution costs than traders with ex ante transaction price information. We also find evidence that trade size has little explanatory power after controlling for a trader's ex ante transaction price information and broker‐client relationships.     

Systematic risk, and oil price and exchange rate sensitivities in Asia-Pacific stock markets

This paper examines the relationship between beta risk and realized stock index return in the presence of oil and exchange rate sensitivities for 15 countries in the Asia-Pacific region using the international factor model. Thirteen of the 15 countries have the expected beta signs and show significant sensitivity to domestic risk when the world stock market is in both up and down modes. In terms of oil sensitivity, only the Philippines and South Korea are oil-sensitive to changes in the oil price in the short run, when the price is expressed in local currency only. Basically no country shows sensitivity to oil price measured in US dollar regardless whether the oil market is up or down. Nine countries are affected by changes in the exchange rate. In terms of relative factor sensitivity distribution, one is willing to conclude that these stock markets are more conditionally sensitive to local currency oil price changes than to beta risk wherever the relationships are significant.     

Endogenous pricing to market and financing costs

This paper explains why relative PPP should hold more tightly in emerging markets, and why pricing to market would be observed more frequently in the OECD countries. It studies the endogenous determination of pricing to market, in a real option model with time-dependent transportation costs, where the future terms of trade are random. Allowing time-dependent transportation costs adds a dimension of investment to the pre-buying of imports, implying that financial considerations determine the frequency of pricing to market, and the deviations from relative PPP. If the expected discounted cost of last minute delivery is higher than pre-buying, one exercises the option of spot market imports if the realized terms of trade are favorable enough. Pricing to market is observed in countries characterized by low terms of trade volatility and low financing costs. In these circumstances, imports are pre-bought, and the spot market for imports is inactive. In countries where the financing costs and the terms of trade volatility are high, few imports are pre-bought, the price of imports is determined by the realized real exchange rate, and a version of relative PPP holds. With an intermediate level of terms of trade volatility and of financing costs, a mixed regime is observed. If the realized real exchange rate is weak, pricing to market would prevail, increasing consumers’ welfare by shielding them from the adverse purchasing power consequences of weak terms of trade. If the realized real exchange rate is favorable enough, more imports are purchased in the spot market, and the relative PPP would hold. Higher financing costs increase the cost of pre-buying imports, reducing thereby the frequency of pricing to market, increasing the expected relative price of imports, reducing the expected deviations from relative PPP, and reducing welfare.     

Dynamics and Politics in Regional Integration Arrangements: An Introduction

Overwhelming evidence links openness and economic growth. Inrecent years many developing countries have attempted to liberalizetheir trade and investment regimes, mostly through autonomousunilateral liberalization. At the same time, a growing numberof governments have begun to explore and participate in regionaltrading agreements. The agreements grant reciprocal trade preferencesto participating countries, resulting in discrimination againstnonmembers. The causes and consequences of regional integration have givenrise to an extensive and vigorous debate among both scholarsand policymakers. However, the quality of this debate has beenseriously hampered by the absence of clear analytical modelsand empirical evidence on many of the factors under discussion.Few of the recent arguments in favor of regional integrationarrangements have been satisfactorily formalized or tested.To address some of these issues, a World Bank research programfocuses on new and developing country aspects of regionalism.The program explores lacunae in the traditional static analysisof regional integration arrangements; addresses the dynamiceffects of integration, the economics of deep integration, andthe politics and political economy of regional integration arrangements;and compares regionalism with multilateralism. The articlesin this symposium address the topics of dynamics, politics,and political economy in regional integration agreements.     

Efficiency and the Bear: Short Sales and Markets Around the World

We analyze cross‐sectional and time‐series information from 46 equity markets around the world to consider whether short sales restrictions affect the efficiency of the market and the distributional characteristics of returns to individual stocks and market indices. We find some evidence that prices incorporate negative information faster in countries where short sales are allowed and practiced. A common conjecture by regulators is that short sales restrictions can reduce the relative severity of a market panic. We find strong evidence that in markets where short selling is either prohibited or not practiced, market returns display significantly less negative skewness.     

Adverse selection costs,trading activity and price discovery in the NYSE: An empirical analysis

This paper studies the role that trading activity plays in the price discovery process of a NYSE-listed stock. We measure the expected information content of each trade by estimating its permanent price impact. It depends on observable trade features and market conditions. We also estimate the time required for quotes to incorporate all the information content of a particular trade. Our results show that price discovery is faster after risky trades and also at the extreme intervals of the session. The quote adjustment to trade-related shocks is progressive and this causes risk persistency and unusual short-term market conditions.     

Economic integration and the choice of commodity tax base with endogenous market structures

This paper analyzes the choice of commodity tax base when countries set their taxes noncooperatively in a two-country symmetric reciprocal dumping model of intraindustry trade with free entry and trade costs. We show that the consumption base (destination principle) dominates the production base (origin principle) when trade costs are high or demand is linear. For lower levels of trade costs and nonlinear demand, the welfare ranking of the two tax bases is ambiguous. Hence, there is no clear preference for a tax principle with an ongoing movement toward closer economic integration.     

亚太自贸区法律框架构建路径研究

习近平主席在2014年APEC北京峰会上倡议“启动亚太自贸区建设”,这表明中国愿意引领和推动这项重要工作。面对“一带一路”倡议带动的中国新一轮对外开放以及亚太地区大国之间在经济一体化进程中的激烈博弈,亚太自贸区建设何去何从,是考验中国人智慧和能力的议题。如果选择TPP这一路径,等于将构建亚太自贸区的主导权拱手让给别人;如果与TPP分道扬镳另辟蹊径,会分化亚太地区,进而影响“一带一路”倡议的整体部署。一个务实的选择是以中国目前正在推动的“区域全面经济伙伴关系协定”(RCEP)为基础,结合中国韩国自由贸易协定建立中、日、韩自由贸易区,进而引导亚太自贸区法律制度向TPP等国际高标准靠拢,同时采取开放姿态,允许个别APEC成员暂时不加入亚太自贸区,也允许非APEC国家和地区加入亚太自贸区。     

Profitability of pairs trading strategy in an illiquid market with multiple share classes

We investigate the practical issues of implementing the self-financing pairs portfolio trading strategy presented by Gatev et al. (2006). We also provide new evidence on the profitability of pairs trading under different weighting structures and trade initiation conditions. Using data from the Finnish stock market over the period 1987–2008, we find pairs trading to be profitable even after allowing for a one day delay in the trade initiation after the signal. On average, the annualized return can be as high as 12.5%, though requiring trading on days a pair is traded lowers the return approximately by three percentage points. On the other hand, lowering the threshold for opening a pair is found to increase returns even after accounting for trading costs, indicating that there might be a more optimal trade initiation threshold available than that presented in earlier literature. The profits are not related to market risk. Pairs trading strategy is found to produce positive alpha during the sample period.     

Bonus schemes and trading activity

Little is known about how different bonus schemes affect traders' propensity to trade and which bonus schemes improve traders' performance. We study the effects of linear versus threshold bonus schemes on traders' behavior. Traders buy and sell shares in an experimental stock market on the basis of fundamental and technical information (past share price evolution, realized earnings, analysts' earnings forecasts, and evolution of the market index). We find that linear and threshold bonus schemes have different effects on trading behavior: traders make more transactions but of a smaller size under the threshold than under the linear bonus scheme. Furthermore, transaction frequency significantly decreases when bonus thresholds are reached but only after building in a safety margin. Under the threshold scheme, the traders' performance is lower (even when there are no transaction costs) than under the linear bonus scheme as a consequence of poorer market timing. This is especially the case when earning money by trading is relatively difficult (i.e., under low profitability conditions). Nevertheless, under low profitability conditions, traders seem to collect more information about the relationships between share price and market returns, earnings, and earnings forecasts, put more effort into understanding those relationships, and thus eventually learn to perform better.     

Brokers and Order Flow Leakage: Evidence from Fire Sales

Using trade‐level data, we study whether brokers play a role in spreading order flow information in the stock market. We focus on large portfolio liquidations that result in temporary price drops, and identify the brokers who intermediate these trades. These brokers’ clients are more likely to predate on the liquidating funds than to provide liquidity. Predation leads to profits of about 25 basis points over 10 days and increases the liquidation costs of the distressed fund by 40%. This evidence suggests a role of information leakage in exacerbating fire sales.
