Determining Opportunities for U.S. Exports of Consumer-Oriented Foods to African Regional Markets

Abstract

This study examines the level of trade between the U.S. and Africa for consumer-oriented agricultural products during the 1990s. To achieve this objective, we propose six congruent regional African markets and examine patterns of U.S. trade with Africa on consumer-oriented agricultural products. The reason for such groupings is to identify trade flow differences and similarities between the U. S. and each of these regional groups. The results shed light on the extent to which U.S. exporters of consumer food products are capitalizing on the emerging markets of Africa. The graphing technique used in the study, in combination with trend stability measures for the six proposed congruent regional African markets, introduce a method for identifying market opportunity.     

Intraday Price Discovery in the DJIA Index Markets

Abstract:  This paper explores the dynamics of price discovery between the Dow Jones Industrial Average (DJIA) index and its three derivative products: the DIAMOND exchange-traded fund (ETF), the floor-traded regular futures, and the electronically traded mini futures. Even though the American Stock Exchange is the primary listing exchange for the ETF, the analysis indicates that the electronically traded ETF on the Archipelago (ArcaEx) electronic communications network dominates the price discovery process for DIAMOND shares. The E-mini futures contribute the most to price discovery, followed by the ArcaEx DIAMOND. The DJIA index and regular futures contribute least to price discovery. The analysis is repeated using the derivatives of the S&P 500 index as a robustness check. The results indicate that multi-market trading ensures greater pricing efficiency. Informed traders favor electronic trading because of immediate and anonymous trade execution.     

Trading volume and stock market volatility: The Polish case

Relying on the mixture of distributions hypothesis (MDH), this paper investigates the relationship between daily returns and trading volume for 20 Polish stocks. Our empirical results show that in the majority of cases volatility persistence tends to disappear when trading volume is included in the conditional variance equation, which is in agreement with the findings of studies on developed stock markets. However, we cannot confirm the testable implications of the MDH in all cases, which indicates that future research on the causes and modeling of Polish stock market volatility is necessary.     

Does trading volume detect information content in earnings reconciliations of foreign firms?

Currently, foreign firms trading securities on U.S. markets provide periodically a quantitative reconciliation of selected financial data consistent with U.S. GAAP (hereafter referred to as reconciled information) in Form 20-F. The SEC is examining whether users believe that this reconciliation process provides additional information above that provided by the foreign GAAP earning announcement and whether this incremental information enhances usefulness for market participants. We examine whether the reconciliation affects a primary indicator of information usefulness: the trading volume of capital markets participants.We use a regression model to examine the relation between a measure of abnormal trading volume and four firm-specific variables in the firm's information environment: similarities of accounting systems, analyst following, difference between reconciled earnings and foreign GAAP earnings, and dispersion of analysts’ expectations. We find a significant relation between abnormal volume and the reconciled earnings number and between abnormal volume and the dispersion of analysts forecasts. Our findings suggest that market participants may use the 20-F reconciliation in trading decisions.     

中国经济增长与环境污染——基于时序数据的经验分析(1985～2003)

本文选用1985￣2003年期间我国的六类环境污染指标,从时序维度考察了环境污染与我国人均收入变化之间的长期均衡关系和相互作用机制。首先,基于MaddalaandKim提出的改进的Johansen协整检验结果表明,在具有协整关系的四类变量中,只有二氧化硫排放总量与人均GDP之间存在正的协整关系,其他三类污染指标(工业废水排放量、工业烟尘排放量、工业固体废弃物排放量)与人均GDP之间协整关系均为负,这表明发展中国家的经济增长并不必然导致环境的恶化;其次,分别基于误差修正模型的因果关系检验与TodaandYamamoto提出的Granger因果检验方法考察了六类污染指标与人均GDP之间的双向因果关系,研究发现环境污染与我国人均GDP之间的一般规律:人均GDP是导致污染排放量变化的重要原因,但污染排放并不是导致人均GDP变化的原因。     

Internet auctions with many traders

We study a multi-unit auction environment similar to eBay. Sellers, each with a single unit of a homogeneous good, set reserve prices at their own second-price auctions. Each buyer has private value for the good and wishes to acquire a single unit. Buyers can bid as often as they like and move between auctions. We characterize a perfect Bayesian equilibrium for this decentralized dynamic mechanism in which, conditional on reserve prices, an efficient set of trades occurs at a uniform price. In a large but finite market, the sellers set reserve prices equal to their true costs under a very mild distributional assumption, so ex post efficiency is achieved. Buyers’ strategies in this equilibrium are simple and do not depend on their beliefs about other buyers’ valuations, or the number of buyers and sellers.     

The effectiveness of FERC’s transmission policy: is transmission used efficiently and when is it scarce?

We investigate the impact of FERC’s policy to create Independent System Operators (ISOs) that independently manage regional electricity transmission resources and institute regional electricity exchange markets. Our analysis examines how the formation of the PJM ISO affected inter-regional electricity trading costs during the period from March 1997 to June 2002. We also examine how ISO formation affected the likelihood of encountering “congestion” in trading electricity between PJM and adjoining regions (particularly the New York ISO and the more loosely organized East Central Area of Reliability (ECAR)). In addition, our analysis estimates the marginal economic value of increased inter-regional transfer capability.      

投资者交易对信息的不平衡性反应——基于交易量视角的研究

一直以来,国内学者从交易量视角研究信息如何影响交易行为的文献并不多见。本文采用Bessembinder等(1996)定义的度量信息的代理变量对2000年1月至2006年12月A股市场上750只股票构建组合的交易量进行实证研究,发现市场层面的利好和利空信息对交易量有着非对称的影响,而公司层面信息的影响却是对称的;进一步的研究表明交易量在牛市和熊市中受到上述两个层面信息影响程度也是不相同,最后本文尝试从我国特有的制度因素以及行为金融学的角度对上述实证结果给出解释。     

FTA betwee China and Korea

Under the regional cooperation being a main trend of the World’s economic development,East Asia should make China and Korea as a breakthrough,build Sino-Korean free trade district,and then push the development of the whole East Asia’s regional economic cooperation.Both China and Korea want to contribute to FTA and keep the dose geographic,humanistic and trade relation.Both countries’ political relation has been improving.In the IT industry,the focus of sino-Korean FTA,sino-Korean IT industries develop quickly and possess the cooperative basis.While in the FTA’s construction,IT industries’ cooperation faces the obstacles:Sino-Korean economic nationalism; the existence of huge china trade deficit for sino-Korean trade;the copyright dispute in the software development.Sino-Korea must take the corresponding measures in order to push the sino-Korean substantial development.     

Entry, exit and trading profits: A look at the trading strategies of a proprietary trading team

We examine the behavior of a 15 strong proprietary stock trading team and show how consistent intraday trading profits were generated. The team, who worked for a large US direct access trading firm, executed over 96 thousand trades in 3 months in 2000. Profitable intraday trading occurred in an anonymous dealer capacity, on both long and short positions, especially when volume and price volatility were higher. The traders rapidly entered long (short) positions when the number of dealers and size become greater on the bid (offer) side of the spread. Profits were taken early against the trend.
