Wealth Effects of Takeovers in Merger Activity Eras: Empirical Evidence from the UK

Existing studies on the assessment of shareholders' gains in takeovers have not taken the characteristics of the prevailing economic activity period into consideration. This study investigates the wealth effects to shareholders in the event of a merger and acquisition transaction by analysing 124 cases in the UK. The paper differs from previous studies in that it examines the abnormal returns found in two different economic periods. These include a boom period, characterised by high merger activity era (HMAE) and a trough period, characterised by low merger activity era (LMAE). The sample firms were categorised into friendly mergers and hostile takeovers— both successful and unsuccessful. The empirical findings derived from this work revealed that upon the differentiation of the two periods, the wealth effects to shareholders in the different transactions is related to the prevailing performance of the economy.     

中国出口面临双重挑战

【新加城星展银行4月16日】目前，中国出口部门面临着结构性与周期性的双重挑战。结构性挑战在于，原材料、能源和劳动力成本都在攀升，人民币也在升值周期性挑战在于，全球需求已陷入疲软。这种双重挑战虽不会击垮中国经济，但也会造成明显的影响。     

Price discovery in the foreign exchange futures market

Examination is made of the relative contributions to price discovery of the floor and electronically traded euro FX and Japanese yen futures markets and the corresponding retail on‐line foreign exchange spot markets. GLOBEX electronic futures contracts provide the most price discovery in the euro; the on‐line trading spot market provides the most in the Japanese yen. The floor‐traded futures markets contribute the least to price discovery in both the euro and the Japanese yen markets. The overall results show that electronic trading platforms facilitate price discovery more efficiently than floor trading. Futures traders may also extract information from on‐line spot prices. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:1131–1143, 2006     

The Impact on IPO Performance of More Stringent Listing Rules with a Pre-listing Earnings Requirement: Evidence from Hong Kong

Abstract:  This study considers the impact of a change to listing rules covering IPO performance in the Hong Kong stock market. The change, introduced in 1994, imposed a three-year prelisting earning requirement on new issues. The objective of this research is to screen out a subset of poor IPO performers. We find there is no significant difference in performance between IPOs before and after the regulatory change. We further divide our sample of IPOs registered before the regulatory change into two sub-samples: those that did and those that did not fulfil the earnings requirement. The result shows that there is no significant difference in performance between the two IPO sub-samples. This implies that the existence of pre-listing earnings does not guarantee good long-term IPO performance and the pre-listing earnings of new issues is not an effective screen for 'bad' IPO performers. This study further analyses the rationale for rule change in the context of recent developments in the Hong Kong stock market and concludes that the rule change is part of the reform programme aimed at introducing a second board market for small companies and at attracting more China-related listings to the main board.     

Risk Premia in Foreign Currency Futures: A Reexamination

This paper reexamines the significant autocorrelation results of foreign currency futures reported by Liu and He [12] in this journal. It argues that extremely thin trading early in the life of individual futures contracts induces unreliable results in [12]. Moreover, the Monte Carlo results clarify the power performance between Lo and MacKinlay's [13] variance ratio tests and Diebold's [3] Q-statistics; both tests are used by Liu and He.     

A fixed point algorithm with economic applications

A new fixed point algorithm applicable to large scale economic problems is developed. Motivated by successive approximation the algorithm iterates on a convex combination of the traditional price to price map and the identity map. The actual combination used is determined from the convergence error of the previous iteration. The specified convex combination is guaranteed to be a contraction if the original map is Lipschitz continuous and antitonal. These sufficient conditions are shown to be weaker than the contraction requirement. A simple supply-demand example is presented to show the advantages of this algorithm over successive approximation.     

ESTIMATION OF TIME‐VARYING ADJUSTED PROBABILITY OF INFORMED TRADING AND PROBABILITY OF SYMMETRIC ORDER‐FLOW SHOCK

Recently, Duarte and Young (2009) studied the probability of informed trading (PIN) proposed by Easley et al. (2002) and decomposed it into two parts: the adjusted PIN (APIN) as a measure of asymmetric information and the probability of symmetric order‐flow shock (PSOS) as a measure of illiquidity. They provide some cross‐section estimates of these measures using daily data over annual periods. In this paper we propose a method to estimate daily APIN and PSOS by extending the method in Tay et al. (2009) using high‐frequency transaction data. Our empirical results show that while PIN is positively contemporaneously correlated with variance, APIN is not. On the other hand, PSOS is positively correlated with daily average effective spread and variance, which is consistent with the interpretation of PSOS as a measure of illiquidity. Compared to APIN, PSOS exhibits clustering and sporadic bursts over time. Copyright © 2012 John Wiley & Sons, Ltd.     

Single-stock futures: Evidence from the Indian securities market

Although single-stock futures (SSFs) are useful multi-purpose stock derivatives, they have not received much attention in developed markets. We analyze SSFs in the Indian market to understand their contribution in price leadership. The findings indicate that trades in the stock market contribute more to price discovery than trades in the SSF market (72% and 28%, respectively), while quotes in the SSF market are more price innovative than quotes in the stock market (39% and 61%, respectively). Our analysis suggests that while stock and SSF trade returns have predictive ability for each other, in the case of quotes, only SSF quotes have predictive ability for stock and SSF returns.     

The Resource-Based View of Competitive Advantage in Two-Sided Markets

abstract    Using two-sided markets as a specific market context, we show that cross-group network effects can turn the participants of a two-sided network into critical resources. In two-sided markets such as payment cards and personal computer operating systems, two groups of agents interact with each other via a common network platform; the value of joining the network for agents in one group depends on the number of participants in the other group. In these markets, resource heterogeneity is represented by different sizes of existing networks; resource accumulation possesses all five characteristics of asset-stock accumulation summarized by Dierickx and Cool. The unique resource accumulation process provides an isolating mechanism for large networks to sustain their resource and competitive advantages. Using two dynamic systems models, we show that resource heterogeneity (i.e. varying initial network sizes) is a source of sustained competitive advantage for two-sided networks and has significant impact on long-term competition dynamics. The findings illustrate the importance of incorporating market context in the research of the resource-based view of competitive advantage.     

Multi-market trading in the Eurodollar futures market

On March 18, 2004, the London International Financial Futures and Options Exchange launched trading in Eurodollar futures contracts in an attempt to compete with a U.S. rival, the Chicago Mercantile Exchange. The Chicago Mercantile Exchange responded to the challenge by introducing several policy changes that aided the transfer of its trading volume in Eurodollar futures from open outcry to the electronic trading platform, Globex, thereby retaining its market share. We compare trading volume, effective spread, and price discovery in Eurodollar futures at the Chicago Mercantile Exchange before and after the London International Financial Futures and Options Exchange began trading the same contract. We find a general increase in trading volume on Globex beginning October 2003, way before the London International Financial Futures and Options Exchange launched its contract. Globex provides greater price discovery than open outcry during the entire time period under study. Our research thus supports the global trend of conversion of traditional open outcry systems into electronic exchanges.
