Market integration and contagion: Evidence from Asian emerging stock and foreign exchange markets

This paper examines whether Asian emerging stock markets (India, Korea, Malaysia, Philippines, Taiwan, and Thailand) have become integrated into world capital markets since their official liberalization dates by estimating and testing a dynamic integrated international capital asset pricing model (ICAPM) in the absence of purchasing power parity (PPP) using an asymmetric multivariate GARCH(1,1)-in-Mean approach. Also examined in this paper is whether there are pure contagion effects between stock and foreign exchange markets for each Asian country during the 1997 Asian crisis. The empirical results show that first, both currency and world market risks are priced and time-varying, suggesting that an international asset pricing model under PPP and constant price of risk might give rise to model misspecification. Second, the stock markets for India, Korea, Malaysia, Philippines, and Thailand were segmented from the world capital markets before their liberalization dates, but all six markets have become fully integrated since then. Third, the market liberalization has reduced the cost of capital and price volatility for most of the countries. Finally, as for the contagion effects, strong positive impact of return shocks originating from the domestic stock market to its foreign exchange market during the crisis is found. This dynamic relationship between stock market and foreign exchange market is consistent with stock-oriented exchange rate models.     

International financial markets: Control or liberalization?

Exchange rates, interest rates and share prices are subject—at least occasionally—to great fluctuations. Diverse economists regard the volatility of international financial markets as a threat to the goods and labour markets. They blame the price turbulences on the speculative behaviour of a large section of market participants, and claim that the deregulation and liberalization of the international financial markets in the eighties has therefore already gone too far. Under discussion today are approaches to a re-regulation of the money, capital and foreign exchange markets. These proposals are evaluated in the following paper.     

Market presence, contestability, and the terms-of-trade effects of regional integration

This paper examines the impact of market presence and contestability on the price behavior of US exporters in Brazil’s market when MERCOSUR and MFN trade liberalization take place. Using detailed panel data on trade and tariff rates, we find that both the preferred supplier’s market presence and threat of entry lower (raise) the US price reaction to MFN (preferential) trade liberalization, with similar quantitative effects. Thus, presence in, or threat of entry into, partners’ markets implies lower optimal MFN tariffs, and regional agreements can have pro-competitive effects in contestable markets. We also examine the ‘symmetry’ hypothesis between the effect of tariffs and exchange rates.     

Trade liberalization and the allocation of labor between households and markets in a poor country

We consider the relationship between relative price changes and the allocation of labor between households and the formal wage labor market in the context of Vietnam's liberalization of its rice trade in the 1990s. Many individuals in poor economies work within their own household rather than in formal labor markets. We find that larger rice price increases in a community are associated with declines in hours adults devote to work within the household and increases in time spent in the wage labor market. We also observe increased specialization in household economic activities accompanying these shifts in hours towards wage work. Our results are consistent with the idea that a growth in the extent of the market shifts production and labor from households to markets during development, thereby inducing gains from specialization. Thus, the reallocation of labor between households and markets in response to a trade liberalization might be an important component in understanding the link between trade and growth in very poor economies, currently the focus of the Doha WTO negotiation round.     

The impacts of RMB internationalization on onshore and offshore RMB markets

Using the DCC-GARCH model, this study considers distinctive features of China's foreign exchange market to investigate the impacts of RMB internationalization on exchange rates in onshore and offshore markets in different stages during 2010–2017. The results show that policies concerning RMB internationalization, such as interest rate liberalization, exchange rate liberalization, and capital market internationalization, have different impacts on the central parity rate, onshore exchange rate, and offshore exchange rate. In terms of exchange rate liberalization, as the daily trading band was gradually widened in 2012–2015, the onshore exchange rate followed the offshore exchange rate more closely. The central parity rate functioned as a managed floating role. It stabilized onshore and offshore exchange rate fluctuations, while allowing partial marketization. After the exchange rate reform on August 11, 2015, the central parity rate plays a benchmark role based on a more market-oriented price formation mechanism. It makes the central parity rate regain pricing power in onshore and offshore markets. Further, it promotes exchange rate liberalization and RMB internationalization. Nevertheless, with the slowdown of China's economic growth and the narrowing of the interest rate differential between China and the US, the RMB is under pressure to depreciate, and its volatility increases significantly.     

Doha development agenda: implications for the US and world cotton markets

This study analyzed two scenarios that considered a reduction of the US aggregate measure of supports (AMS) payments by 60% over a five-year period. In the first scenario, which considered a unilateral action by the US, the targeted AMS payments reduction would require a 12% cut in the US target price and an 8% cut in the loan rate. This would lead to a 3% decline in US cotton production, a 3% rise in world cotton price, and a 26% decline in US cotton net farm income at the end of the implementation period. The second scenario analyzed the case in which the US AMS payments reduction is concomitant with multilateral tariff and subsidy eliminations from the rest of the world. Under this scenario, fewer cuts in the US loan rate and target price (i.e. 9 and 4%) were required to achieve the 60% AMS reduction because of market liberalization from the from the rest of the world. However, US cotton producers' net farm income still declined by 18%.     

The effect of trade liberalization on child labor

The question of how trade liberalization affects the employment of children in developing economies is at the core of the debate on globalization. Trade theory predicts that an increase in the price of an exported good could either increase or decrease child labor depending on the magnitudes of the substitution and income effects. In this paper, we study the relationship between changes in the relative price of an exported commodity and child labor using household-level data from within a poor country. In particular, we relate child labor to regional and intertemporal variation in the real price of rice surrounding national and international rice market integration in Vietnam. We find that higher rice prices are associated with declines in child labor. Income effects play an important role in this relationship. Rice price increases are associated with the largest declines in child labor in households that are large net producers of rice. These findings show that greater market integration can be associated with less child labor. Moreover, our results suggest that the use of punitive trade sanctions on exports from developing countries to eradicate child labor is unlikely to yield the desired outcome.     

Measuring Prices and Price Competition Online: Amazon.com and BarnesandNoble.com

Despite the interest in measuring price sensitivity of online consumers, most academic work on Internet commerce is hindered by a lack of data on quantity. In this paper we use publicly available data on the sales ranks of about 20,000 books to derive quantity proxies at the two leading online booksellers. Matching this information to prices, we can directly estimate the elasticities of demand facing both merchants as well as create a price index for online books. The results show significant price sensitivity at both merchants but demand at BarnesandNoble.com is much more price-elastic than is demand at Amazon.com. The data also allow us to estimate the magnitude of bias in the CPI due to the rise of Internet sales.     

市场潜力、贸易自由化与地区工资差距

在新经济地理学的框架下,本文构建理论模型研究市场潜力和贸易自由化与地区工资差距的关系,根据中国1993－2012年的省际面板数据,采用工具变量二阶段最小二乘法实证检验市场潜力和贸易自由化对地区工资水平的影响效应。研究结果表明,市场潜力和贸易自由化对地区工资水平均有显著为正的影响作用,且二者还存在替代关系。进一步的分析发现,贸易自由化程度较高的沿海地区,其市场潜力对地区工资水平的影响较小,而在内陆地区则恰好相反。     

Hedonic study on mobile telephony market in France: pricing–quality strategies

This paper provides a hedonic price analysis of mobile telephony services for the French market. We adopt the hedonic price theory to examine the relationship between changes in price levels and the evolution of the market for mobile telecommunications industry in France from June 1996 to December 2002. The results support the hypothesis that there was price competition between service providers in the earlier period. There were also large differences in prices set by individual service providers which, however, did not persist over time. Next, using estimates from hedonic-price equation for each operator separately, we found that the three-mobile providers seemed to adopt similar pricing strategies over the period 1996–2002. Quality indexes are also calculated. The results of a comparative analysis indicate that in the period 2000–2002 neither the quality nor the price indexes show significant changes for the three mobile providers. These results are of some consequence, especially after the French competition authority decision in December 2005 which stated the existence of collusion on the mobile market during the same period (2000–2002). Surprisingly, our primer results supporting the assumption of potential collusive conduct in France are not re-affirmed when comparing the French and German markets.     

Access of Tunisian Fruits and Vegetables to the EU Market: Potential Impacts of the Revision of the Entry Price System

Agricultural trade flows worldwide continue to be subject to country restrictions of a tariff and non-tariff nature. This is more so in the case of fruits and vegetables in view of their multiplicity. This hinders the exports of these products, which is an important objective sought by the economy of Tunisia. This article simulates the potential consequences of a possible opening up of the European market borders on fruits and vegetables coming from Tunisia and the rest of the world (ROW), following alternative tariff reduction schemes of the entry price mechanism practiced by the EU, particularly in its ad-valorem duty. The analysis uses a partial equilibrium model that takes into consideration economic aspects related to the exports of these products, regardless of their interactions with other agricultural commodities. The model is composed of a series of behavioral equations describing excess demand and supply of fruits and vegetables of all trading partners and attempts to simulate “international” market equilibrium for these commodities. Tomatoes, oranges and peaches were selected for the analysis and three trading blocs were taken into consideration: The European Union, Tunisia and the ROW. Two policy scenarios were examined (a) reduction by one third of the ad-valorem tariff and (b) its total elimination. The results suggest that the impacts would be concentrated in specific periods, varying with products and regions. In addition to possible trade volumes, Tunisia and other countries may also gain in value from exports. A significant increase in the prices of peaches and tomatoes for Tunisia would result from the liberalization process of the EU market. Volumes and prices of EU domestic supplies would however exhibit moderate reductions.     

Estimating demand for cellular phone service under nonlinear pricing

Cellular phone carriers typically offer complicated nonlinear tariffs. Consumers make a discrete choice among several rate plans. Each plan has a nonlinear price schedule, and price is usually lower for in-network calls. I present an empirical framework to estimate demand under such nonlinear pricing schemes by using parsimonious carrier-level data and apply the estimation method to analyze the market in Taiwan. I evaluate the impacts of termination-based pricing schemes on the market structure by counterfactual simulations. There is no evidence showing that the network effect resulting from termination-based pricing has significant effects on market structure.

非流通股与过度股权融资

In the Chinese stock market, the price of exchangeable stock is determined by the discounted future uncertain cash flow, while the price of non-circulating stock depends on per book value. In general, because investors holding non-circulating equity maintain the control power, corporate finance and investment decisions reflect their interests. The pricing mechanism of non-circulating stock violates the basic pricing principle of the capital market. Therefore, corporate finance decisions deviate from the NPV (net present value). As a result, excessive equity financing problems would occur in the listed companies. Translated from Shijie Jingji Wenyuan 世界经济文源 (World Economic Forum), 2004, (4): 41–50     

How does stock market liberalization influence corporate innovation? Evidence from Stock Connect scheme in China

Using China's Stock Connect program as a quasi-natural experiment, we assess the impact of stock market liberalization on corporate innovation. The baseline result based on a difference-in-differences (DID) estimation suggests that allowing foreign investors to buy domestic stocks has a beneficial effect on Chinese firms' innovative outputs. Specifically, eligible firms affected by the Stock Connect scheme generate more and higher quality patents than other unaffected firms subsequently. Furthermore, we explore potential channels that may explain this beneficial effect in terms of improving corporate governance, reducing information asymmetry, and mitigating financial constraints. In addition, the effect is more pronounced for firms in high-tech industries. However, we find that the influence of stock market liberalization is insignificant in state-owned firms. Besides, the findings are generally robust to different measures of innovation and different methods of estimation. Overall, this paper provides new insights into understanding the positive effect of stock market liberalization in emerging market economies.     

Trade liberalization and strategic outsourcing

This paper develops a model of strategic outsourcing. With trade liberalization in the intermediate-product market, a domestic firm may choose to purchase a key intermediate good from a more efficient foreign producer, who also competes with the domestic firm for a final good. This has a strategic effect on competition. Unlike the outsourcing motivated by cost saving, the strategic outsourcing has a collusive effect that could raise the prices of both intermediate and final goods. Trade liberalization in the intermediate-good market has a very different effect compared with trade liberalization in the final-good market.     

Financial market liberalization and the pricing of idiosyncratic risk

We test the impact of idiosyncratic risk on stock returns for emerging markets that experience financial market liberalizations. Idiosyncratic risk is positively associated with returns prior to financial market liberalization, but liberalization diminishes this effect. Moreover, prior to liberalization, the number (concentration) of stocks available in the market is negatively (positively) correlated with the pricing of idiosyncratic risk. The decrease in the pricing of idiosyncratic risk can explain the reduction in the cost of capital around liberalizations. Additionally, the change in the pricing of idiosyncratic risk may be a useful measure of the success of financial market liberalization.     

Global agricultural trade liberalization: Is Sub-Saharan Africa a gainer or loser?

This paper analyzes the potential impact of agricultural trade liberalization on Sub-Saharan Africa. We used the Agricultural Trade and Policy Simulation Model to estimate the potential effects of agricultural trade liberalization, mainly in the US and EU, on the world-market prices of agricultural commodities. We then used the estimated price changes to assess the impact of these reforms on net-food importers as well as other Sub-Saharan African countries that enjoy preferential trade agreements with the EU and US. The results indicate that the world market prices of all commodities imported by Sub-Saharan Africa are expected to rise while the prices of the key export commodities of the region would either decline or remain unchanged. Given that the prices of major food commodities are expected to rise, net-food-importing countries will experience increasing import bill, thus leading to welfare loss. Major Sub-Saharan Africa sugar exporters who are beneficiaries of preferential agreements such as the EU sugar protocol and US AGOA initiative will become losers as preferences erode due to global liberalization. Thus, the region is expected to generally become a net loser from the current WTO reform modalities.     

论中国利率市场化进程与利率期货的推出

中国利率市场化的进程正在有步骤地加速推进,利率的市场化必然带来利率波动幅度的加大,如果没有有效的利率风险管理工具作为配套机制,必然会影响利率市场化的顺利进展,也影响到整个金融市场应有作用的发挥.发达国家的经验表明,利率市场化要求利率期货作为利率风险管理的机制予以配合,因此,在推进中国利率市场化的进程中应研究推出利率期货交易的问题.利率期货的最主要承载体是国债期货.根据中国目前利率市场化进展的实际情况,从各类经济实体已经或可能面临的利率风险看,对国债期货的需求日渐强烈.本文的主旨是,在论述中国利率市场化进程中,分析各类经济实体所面临的各种利率风险,以及国债期货对于这一风险管理所起的应有作用,从而得出应当推出国债期货的结论.     

A nearly perfect market?

Internet shopbots allow consumers to almost instantly compare prices and other characteristics from dozens of sellers via a single website. We estimate the magnitude of consumer search costs and benefits using data from a major shopbot for books. For the median consumer, the estimated benefit from simply scrolling down to search lower screens is $6.55. This amounts to about 60% of the observed price dispersion and suggests that consumers face significant search costs, even in this “nearly-perfect” market. Price elasticities are relatively high compared to offline markets (−7 to −10 in our base model). Furthermore, contrary to the common assumption, search intensity is not correlated with greater price sensitivity. Instead, consumers who search multiple screens put relatively more weight on non-price factors like brand.     

Setting price or quantity: Depends on what the seller is more uncertain about

We consider a seller with uncertain demand for its product. If the demand curve were certain, then setting price and setting quantity would be equivalent ways to frame the seller’s problem of choosing a profit-maximizing point on its demand curve. With uncertain demand, these become distinct sales mechanisms. We distinguish between uncertainty about the market size and uncertainty about the consumers’ valuations. Our main results are that (i) for a given marginal cost, an increase in uncertainty about valuations favors setting quantity whereas an increase in uncertainty about market size favors setting price; (ii) keeping demand uncertainty fixed, there is a nonmonotonic relationship between marginal costs and the optimal selling mechanism (setting price or quantity); and (iii) in a bilateral monopoly channel setting, coordination occurs except for a conflict zone in which the retailer’s choice of a selling mechanism deviates from the coordinated channel selling mechanism.
