The purpose of this paper is to investigate the impact of short selling and margin trading on the price discovery and price informativeness of cross-listed firms, using a sample of Chinese firms listed on the China and Hong Kong stock exchanges.

The sample consists of 67 Chinese cross-listed firms on A-share and H-share markets out of which 18 firms are allowed to be sold short/ traded on margin since March 2010. Using pre- and post-event period, the authors compare and contrast various market microstructure variables. The contributions of the home (A-share) and overseas (H-share) markets to the incorporation of new information into prices are calculated following the permanent-transitory approach of Gonzalo and Granger (1995) as well as the adverse selection component of Lin et al. (1995).

The findings indicate that for the group of Chinese cross-listed firms that are not allowed to be sold short or bought on margin, the home (A-share) market contributes more to the price discovery process over time. However, for the group of cross-listed firms that are eligible for short selling and margin trading, the authors observe no significant difference in the contribution of either A- or H-share markets to the price discovery. The contribution of home market for these firms is even lower around the announcement of major events. The authors further find that while the short sale activities appears to be informative, measured by the adverse selection (AS) component of spread, on the whole they have not led the A-share markets to be more informative.

The sample of cross-listed Chinese firms that are allowed to be sold short or bought on margin are rather limited. Hence, the results should be read with some caution.

The removal of short selling constraints appears to improve the contribution of the respective markets to the process price discovery, in the case for larger cross-listed firms.

The authors shed new lights on how the introduction of short selling and margin trading impacts on the price discovery of the Chinese cross-listed firms. A further contribution of the study is the use of high frequency data, while most of the previous studies on the Chinese markets use daily data.

The purpose of this paper is to examine the effects of gravity variables and trade costs on China's export margins.

Following the structural gravity model with firm heterogeneity, the paper measures the extensive margins and intensive margins of China's export across 46 export destinations and estimates the linkage between export margins and its potential determinants.

The empirical results confirm the gravity relationship hold for bilateral trade and export margins. Furthermore, trade costs have different influence on extensive margins and intensive margins as the structural gravity model with firm heterogeneity expected. The paper also shows the rapid growth of China's export is mainly along the intensive margins which are increasing in fixed cost for export.

The paper contributes to the measurements of China's export margins and the empirical research on effects of trade liberalization on China's foreign trade.

The purpose of this paper is to investigate how the announcement and implementation of short sales and margin trading regulation affects Chinese stock returns and trading volume. On 31 March 2010, the Chinese regulators launched a pilot programme, allowing short sales and margin trading for 50 Shanghai Stock Exchange and 40 Shenzhen Stock Exchange stocks.

This paper uses an event study approach to compare market model abnormal returns (ARs) of the pilot firms with two distinct matched firm samples. A volume event study is also conducted to examine abnormal trading activity surrounding the key events in the pilot stocks.

Negative ARs follow both the announcement and implementation of short selling and margin trading. This suggests the negative impact of short sales dominates the positive impact of margin trading on an average. Volume also declines, which is consistent with uninformed investors’ seeking to avoid trading against informed traders.

The paper appears to be the first to address the impact of both the announcement and implementation of short selling and margin trading rule changes on returns and liquidity using individual stock data.

This chapter presents a global computable general equilibrium model with firm heterogeneity based on the Melitz (2003) framework and examines the relative importance of the intensive and extensive margins in the trade expansion following trade liberalization. Using a set of plausible parameters values suggested by empirical studies and calibrating the model to the recent Global Trade Analysis Project (GTAP) global database, our illustrative simulations indicate that the extensive margin accounts for around one-third of the trade growth induced by a reduction in tariffs or variable trade costs. In the case of reducing fixed trade costs, the extensive margin contributes almost 200 percent of the trade expansion, with the intensive margin contributing negatively to trade growth.

The purpose of this paper is to study whether, of China's food and agriculture (agri-food) export, the trade relationships along the extensive margin can transform into short-term ones, and further convert into long-term ones along the intensive margin with survival and maintenance, especially, under what kind of conditions these transformation realize successfully, and what the factors are and how they impact on the length of the trade relationships duration.

The paper comprises three stages: decomposing China's agricultural export data (1999-2008) into highly disaggregated three distinct parts; with the Kaplan-Meier (KM) nonparametric estimation, discovering the practical source of stable and long-term export growth, and the threshold at which the short-run trade relationships deriving from newly established ones convert into long-run ones successfully; by semi parametric estimation through Cox proportional hazard model, preliminarily examining the possible impact of different factors on the trade relationship's hazard rate and duration.

The paper reveals that China agri-food trade pattern at the product level is surprisingly dynamic with newly established trade relations being more likely to fail. While the frequent volatilities of short-term relations at the extensive margin could be used to evaluate the source of short-term export growth especially and effectively, the pattern of negative dependence together with the threshold effect of duration indicates, only when these short-term relations live longer than four years will they substantially contribute to a stable and prolonged export growth. Simultaneously, trade duration significantly correlates to importing country's development status, region it belongs to, product processing degree, export experience and geographical space between trading partners.

To avoid the likelihood of misleading when estimating quantitatively the source of long-term export growth, researchers should be cautious in accurately evaluating the impacts of all possible factors on the two trade margins' performances, which is beyond the scope of this paper though, and a matter of ongoing work on the research agenda.

The study presents a set of important policy implications. Now that turnovers along the extensive margin have little impact on long-term China agri-food export growth, it turns out that improving export survival would result in significantly higher and stable export growth.

By distinguishing the survival of trade relationship channels from their deepening, the discoveries in the paper are crucial to understand the different role the intensive and extensive margins play in China agri-food export growth. The diversified hazard rates of export relations in different duration intervals suggest that the constant hazard rate assumption in Melitz and Bernard et al. is in some sense not appropriate.

The purpose of this paper is to investigate whether the change of margin in Chinese futures markets has policy spillover effects.

The paper constructs a model based on Harzmark and on Chng, taking Chinese futures markets status quo as a single species and restrictions on foreign investment into consideration, introduces the assumptions of spillover effect of speculators, then obtains investor's demand function. Subsequently, the effects of Shanghai Futures Exchange's 11 instances of margin changing are analyzed.

The paper finds that in the Chinese futures market, margin changing has impact on the open interest (OI) and the speculator spillover effect is validated.

The irrational behavior of investors in markets is not taken into account in the model and data about spillover speculators were not directly available.

The paper usefully analyzes the effects of the Shanghai Futures Exchange's 11 instances of margin changing from 2000 to 2007 and examines the actual effects of margin‐changing policy, in the views of OI, trading volume and the externality, the results showing that margin changing has impact on investor structure and validates the existence of the assumed speculator spillover effect.

The purpose of this paper is to discuss the trial implementation of stock index futures trading, margin trading and securities lending in China – approved in principle by the State Council and confirmed by the China Securities Regulatory Commission (CSRC) on January 8, 2010.

The paper describes various preliminary rules and regulations for stock index futures trading, margin trading, and securities lending that have been issued starting in 2006 and the latest regulatory developments, requirements and timing related to the trial implementation.

The stringent requirements imposed by CSRC highlights its cautious approach to the trial process for margin trading and securities lending. By defining “securities lending” as the borrowing of securities and the subsequent sale of those securities in the 2006 Trial Administrative Measures, the regulator appears to leave open the possibility of short selling.

The Announcement has been warmly welcomed by market participants because index futures trading, margin trading and securities lending are expected to significantly add to the Chinese equity market's liquidity and price discovery process in the long run.

The paper provides practical guidance from experienced securities lawyers.

To achieve a full understanding of the role of marketing from plan to profit requires a knowledge of the basic building blocks. This textbook introduces the key concepts in the art or science of marketing to practising managers. Understanding your customers and consumers, the 4 Ps (Product, Place, Price and Promotion) provides the basic tools for effective marketing. Deploying your resources and informing your managerial decision making is dealt with in Unit VII introducing marketing intelligence, competition, budgeting and organisational issues. The logical conclusion of this effort is achieving sales and the particular techniques involved are explored in the final section.

This study aims to consider how migrants may act as channel of diffusion of knowledge which contributes to the dynamics of trade and comparative advantages of EU and MENA countries for the period 1990–2015.

Adopting an IV approach and a gravity framework to instrument for migration, the authors document how variations in stocks of migrants coming from (in) countries that are already competitive exporters of a given product impact on the probability that the destination (home) country starts to export competitively new products or succeed in exporting more intensively.

Controlling for potential confounding factors which can be correlated to knowledge flows and productivity shifts, the authors find trade-promoting effects via migration flows (mostly immigration) between the two areas, testing our hypotheses by different technology classes of products and different specifications.

The contribution of this work to the literature is threefold. First, by providing evidence on international knowledge diffusion induced by migration flows between MENA and EU regions, like no other work before, the authors document the effects of migration on trade and comparative advantages. Second, unlike standard literature on migration-trade link, the authors focus more on long-term structural changes in comparative advantages than on trade volumes. Third, we exploit how the effect of migration on margins of trade varies according to different types of goods, classified by technological level.

Using an original product level database, this article analyzes the nature and dynamics of Swiss specializations during the “first globalization” (1850–1913). I study the comparative advantages, as well as the evolution of the trade structure, in order to understand economic performance differences between Switzerland and France. Despite differences in terms of market size, some common trends are identified. I also argue that Switzerland's skilled labor force, along with an intelligent choice of economic policy, allowed this country to adapt its specialization structure to global demand and enjoy rapid economic growth.
