The determinants of quantile autocorrelations: Evidence from the UK

We empirically analyse the cross-sectional determinants of stock return autocorrelations in the UK in different quantiles of conditional return distributions. Autocorrelations in low quantiles are predominantly positive, whereas those in the remaining quantiles are negative. Autocorrelations in different quantiles depend on different sets of firm and trading characteristics: when returns are normal or high, prices react quickly to information, are driven by positive feedback traders, instantaneous news arrivals, and overshoot, trades are predominantly motivated by hedging/liquidity needs, and measured autocorrelations can be biassed by the bid–ask bounce effect and nonsynchronous trading. However, when returns are unusually low, prices are driven by information arriving sequentially and react sluggishly to it, and are influenced by trading on private information and/or negative feedback traders.     

Are investors compensated for their sophistication and informedness for company takeovers – An Australian study

I determine the sophistication and information level in takeovers for four investor classes which are individuals, nominees (fund managers), superannuation (pension) funds and incorporated companies. I also calculate their takeover returns. I find that the superannuation funds are informed and sophisticated; individuals are informed but unsophisticated; nominees are uninformed but sophisticated; and incorporated companies are uninformed and unsophisticated traders, and that the investors realise a return which is commensurate with their information and sophistication. This study improves on existing takeover return research which assumes, as a group, institutions are synonymously informed and sophisticated, and individuals are synonymously unsophisticated and uninformed.     

Corrections for Trading Frictions in Multivariate Returns

When observed stock returns are obtained from trades subject to friction, it is known that an individual stock's beta and covariance are measured with error. Univariate models of additive error adjustment are available and are often applied simultaneously to more than one stock. Unfortunately, these multivariate adjustments produce non-positive definite covariance and correlation matrices, unless the return sample sizes are very large. To prevent this, restrictions on the adjustment matrix are developed and a correction is proposed, which dominates the uncorrected estimator. The estimators are illustrated with asset opportunity set estimates where daily returns have trading frictions.     

Bayesian estimators of the lognormal–Pareto composite distribution

In this paper, Bayesian methods with both Jeffreys and conjugate priors for estimating parameters of the lognormal–Pareto composite (LPC) distribution are considered. With Jeffreys prior, the posterior distributions for parameters of interest are derived and their properties are described. The conjugate priors are proposed and the conditional posterior distributions are provided. In addition, simulation studies are performed to obtain the upper percentage points of Kolmogorov–Smirnov and Anderson–Darling test statistics. Furthermore, these statistics are used to compare Bayesian and likelihood estimators. In order to clarify and advance the validity of Bayesian and likelihood estimators of the LPC distribution, well-known Danish fire insurance data-set is reanalyzed.     

Divestments and financial distress in leveraged buyouts

This paper investigates the wealth effects of 134 divestments by 41 firms that underwent leveraged buyouts in the 1980s. Stock in these companies is privately owned. Bond returns for publicly traded debt are used to measure the wealth effects of the divestment announcement. These divestments are, on average, not associated with significant wealth effects for the full sample. However, firms that experience financial distress have negative and significant abnormal returns associated with their divestments, while returns in non-event months are insignificant. In contrast, non-distressed firms gain when asset sales are announced. The losses suffered by bondholders in distressed sellers are large and significant when core assets are divested. Bondholders in these firms do not suffer significant losses when non-core assets are divested. Finally, abnormal bond returns are related to the structure of the firms' post-buyout debt. Returns are negatively related to the use of private debt in the capital structure and positively related to the use of subordinated debt.     

Elements of a talent strategy for effective relationship building: A study among bank sales and service providers

This study considers equity sensitivity, emotional labor and organizational commitment as three important variables that play a critical role among sales and service providers at a bank and the effect these variables ultimately have on corporate performance. Using an equity theory perspective, research hypotheses linking the various constructs are formulated. Data are collected from sales and service managers at a community bank and partial aggregation followed by structural equation modeling is used to test the hypotheses. Results are reported, implications to a bank’s talent strategy are drawn, limitations are noted and directions for future research are indicated.     

Trade and information in the corporate bond market

This paper examines the impact of shifting liquidity and institutional trading in the corporate bond market on inferences regarding informational efficiency. We find that when institutional trade dominance and other bond trading features are accounted for, stock leads evidenced in earlier studies surprisingly disappear. Short windows after firm-specific news releases are examined, and bond trading advantages are shown to be pronounced particularly when equity market liquidity is low (during after-market hours). Cross-sectionally, the effect of credit risk and other firm/bond level characteristics are determined. Finally, ‘top bonds’ are identified, and their common ex ante identifiable characteristics are determined.     

When time is (not) money: preliminary guidance on the interchangeability of time and money in laboratory-based risk research

The familiar adage that ‘time is money’ may not be entirely accurate according to research involving hypothetical choice: People’s decisions are less sensitive to temporal expenditures and outcomes than monetary ones. We provide a novel examination of whether similar patterns of risky choice are found for time and money when choices are consequential (i.e. monetary outcomes are obtained and temporal outcomes are experienced) – both for one-shot and repeated choices, over gains and losses. On the aggregate, across decision contexts (described and experienced), choices are similar for time and money. However, on the level of the individual, little relationship between risk preferences for time and money are observed. We discuss the theoretical and practical implications of these findings.     

Prediction in chaotic time series: methods and comparisons with an application to financial intra-day data

Different prediction methods for chaotic deterministic systems are compared. Two methods of reconstructing the dynamics of the systems are considered with a view to producing a profitable trading model. The methods developed are the ‘nearest neighbours’ method and the ‘radial basis functions’ method. The optimal prediction horizon according to the sampling time step, and a reliable method to measure the prediction error are discussed. These methods are applied to the intra-day series of exchange rates, namely DEM/FRF. Developments concerning the importance of noise when chaotic systems are studied are provided.     

The effects of corporate bailout on firm performance: International evidence

Not all corporate bailouts are the same. We study corporate bailouts from around the world during 1987–2005. Among these bailed-out firms, some firms are economically distressed while others are financially distressed. Some firms are bailed out with cash (either as equity or as loans) while others are bailed out with debt relief. Some firms are bailed out by the government while others are bailed out by other stakeholders. We examine these firms’ operating performance before and after their bailouts, but specifically across different bailout types, and we also measure their stock returns surrounding their bailout announcements.     

The Dynamics of Dealer Markets Under Competition

The behavior of competing dealers in securities markets is analyzed. Securities are characterized by stochastic returns and stochastic transactions. Reservation bid and ask prices of dealers are derived under alternative assumptions about the degree to which transactions are correlated across stocks at a given time and over time in a given stock. The conditions for interdealer trading are specified, and the equilibrium distribution of dealer inventories and the equilibrium market spread are derived. Implications for the structure of securities markets are examined.     

Understanding in‐house transactions in the real estate brokerage industry

About 20% of residential real estate transactions in North America are in‐house transactions, for which buyers and sellers are represented by the same brokerage. We examine to what extent in‐house transactions are explained by agents' strategic incentives as opposed to matching efficiency. Using home transaction data, we find that agents are more likely to promote internal listings when they are financially rewarded and such effect becomes weaker when consumers are more aware of agents' incentives. We further develop a structural model and find that about one third of in‐house transactions are explained by agents' strategic promotion, causing significant utility loss for home buyers.     

Can Audit Partners Predict Subordinates' Ability to Detect Errors?

This study examines audit partners' predictions of the ability of managers and seniors to detect financial statement errors. If partners are unable to predict the ability of their subordinates to detect errors, audit effectiveness may be affected. Audit partners are asked to predict which members of the audit team (managers or seniors) are able to detect specific types of errors. These predictions are then compared to errors detected by managers and seniors that are seeded in working papers. The results show that partners (1) exhibit significant overconfidence in the ability of subordinates to detect errors, (2) are more accurate in predicting managers' performance than seniors, (3) are more accurate at predicting subordinates' ability to detect mechanical (simple) errors than conceptual (complex) errors, and (4) are not better at predicting subordinates' ability to detect more frequent and more important errors than less frequent and less important errors.     

价格上限、产品同质性与成本竞争——对再生资源产业竞争问题的新解释

由于再生资源对初始资源的有限替代作用,使得再生资源具有"天然"的价格上限,再生资源企业是在有限的需求空间内进行竞争.同时,用再生资源替代初始资源会带来信息收集、设备技术更换等替代成本,进一步压缩了再生资源企业所面对的需求空间.而资源产品的同质性,以及再生资源产品之间的转换成本,不仅使价格成为影响消费者选择的决定性因素,而且促使大企业在小企业的降价策略下,被淘汰出市场.因此,开拓新的再生资源消费领域,并采取服务差异化战略能够帮助大企业免于在成本竞争中被淘汰.     

The economic woman in Africa

A common theme in traditional African cultures is that God made women the custodians of fire, water, and earth (the elements). Modern African cultures are still based on this belief. African women are responsible for firewood collection, water fetching, and food production. However, there are 2 distinct types of African women that are beginning to evolve as the influences of Western culture begin to set in. Westernized African women are those women who have completed at least 2 years of post secondary school training in a Western educational setting. When these women return to their native cultures, rather than taking positions of power and influence like their male colleagues, they end up working as clerks, telephone operators, and teachers. These Westernized African women rarely return to rural areas to take on the role of custodian of the elements. In cases where modernization does reach the rural areas, women are commonly excluded. Tractors are driven by men, dams and water systems are designed and built by men, trees are cut down by men, trees are cut down by men, and men make the furniture. Technology is having a marginalization effect upon the women of Africa similar to the Westernization of African women. This is not to say that Western education is something to be avoided; however, policies must be put in place to tap this great resource instead of holding it back. Rural women need to gain access to the technology that will help ease their burdens and they must be allowed into planning and decision making process since, after all, they are the custodians of the elements.     

Implied volatilities,stochastic interest rates,and currency futures options valuation: an empirical investigation

Different models of pricing currency call and put options on futures are empirically tested. Option prices are determined using different models and compared to actual market prices. Option prices are determined using historical as well as implied volatility. The different models tested include both constant and stochastic interest rate models. To determine if the model prices are different from the market prices, regression analysis and paired t-tests are performed. To see which model misprices the least, root mean square errors are determined. It is found that better results are obtained when implied volatility is used. Stochastic interest rate models perform better than constant interest rate models.     

The Pricing of Initial Public Offers of Corporate Straight Debt

This study examines the initial-day and aftermarket price performance of corporate straight debt IPOs. We find that IPOs of speculative grade debt are underpriced like equity IPOs, while those rated investment grade are overpriced. IPOs of investment grade debt are typically issued by firms listed on the major exchanges and underwritten by prestigious underwriters. In contrast, junk bond IPOs are more likely to be handled by less prestigious underwriters and are typically issued by OTC firms. Our analysis also reveals that bond rating, market listing of the firm, and investment banker quality are significant determinants of bond IPO returns.     

Insider trading and share repurchases: Do insiders and firms trade in the same direction?

Signaling undervaluation is often considered a primary motive for repurchasing stock, but insider trading activity by repurchasing firms is not always consistent with undervaluation. Net insider buying and selling are both more frequent in quarters when firms are repurchasing non-trivial amounts of stock, with the odds of observing a repurchase the highest in quarters with net insider selling. In multinomial logit models, share repurchases associated with net insider selling are positively related to illiquidity, option exercises by insiders, and pre-repurchase returns and negatively correlated with industry-adjusted book to market ratios when compared to other repurchases. Hence, repurchases when insiders are selling stock are more likely done to support share prices or avoid dilution and are less likely undervaluation signals. We find that insider trades either validate or mitigate the undervaluation signal of the repurchase. Abnormal returns of repurchasing firms with net insider buying versus net insider selling in a given quarter are significantly higher for the quarter immediately after the repurchase and the three subsequent years. For repurchases accompanied by net insider selling, abnormal returns are negligible after only one year.     

Customer value analysis in financial services

This study investigates what creates value for customers and how providers can improve value for their customers. A comprehensive analytical model with a four-step approach is presented and applied in the field of financial services. In a first step, the main customer value drivers are identified and five value dimensions are derived, based on qualitative interviews with customers. These results are then compared to value assumptions made by customer-contact employees, and gaps between customer and employee perceptions are analysed. Based on these identified gaps, a multitude of implications for managing company customer value at the normative, strategic, and operational level of management are derived, and finally implications of findings for service marketing practice and research are discussed.
