Trades and Quotes: A Bivariate Point Process

This article formulates a bivariate point process to jointlyanalyze trade and quote arrivals. In microstructure models,trades may reveal private information that is then incorporatedinto new price quotes. This article examines the speed of thisinformation flow and the circumstances that govern it. A jointlikelihood function for trade and quote arrivals is specifiedin a way that recognizes that an intervening trade sometimescensors the time between a trade and the subsequent quote. Modelsof trades and quotes are estimated for eight stocks using Tradeand Quote database (TAQ) data. The essential finding for thearrival of price quotes is that information flow variables,such as high trade arrival rates, large volume per trade, andwide bid–ask spreads, all predict more rapid price revisions.This means prices respond more quickly to trades when informationis flowing so that the price impacts of trades and ultimatelythe volatility of prices are high in such circumstances.     

Strategic Internet application trends in supply chain management

The Internet is evolving as a powerful force in the new marketplace where the nexus of competition has changed from individual firms to efficient supply chain networks both between firms and within industries. This study explores Internet adoption patterns and operational applications in US supply chain networks. The data reveal that the integration of the Internet into supply chain management applications has increased and has moved away from indiscriminate application of novel Internet technologies towards becoming a focused endeavor with precise expectations and measurable goals. Specifically, the study finds that Internet usage within supply chains is maturing as evidenced by enhanced and increased productivity, reduced costs and increased profit for participating firms.     

Pseudo empirical likelihood method in the presence of missing data

In this paper, we propose an estimator for the population mean when some observations on the study and auxiliary variables are missing from the sample. The proposed estimator is valid for any unequal probability sampling design, and is based upon the pseudo empirical likelihood method. The proposed estimator is compared with other estimators in a simulation study.     

Mixed oligopoly, optimal privatization, and foreign penetration

This paper examines the impact of foreign penetration on privatization in a mixed oligopolistic market. In contrast to the simple framework of single domestic market with foreign entry by entry mode of foreign direct investment (FDI) or exports, our result shows that government should increase the degree of privatization along with increasing proportion of domestic ownership of multinational firms. Furthermore, we show that an increase in domestic ownership of multinational firms raises all domestic private firms' profit and social welfare, while it may either increase or decrease public firm's profit. With the aid of numerical example, intensive competition from private firms in general will enhance the degree of privatization gradually; in particular, the degree of privatization is lower in the presence of multinational firms.     

The price adjustment and lead-lag relations between stock returns: microstructure evidence from the Taiwan stock market

This paper investigates the price adjustment and lead-lag relations between returns on five size-based portfolios in the Taiwan stock market. It finds evidence that the price adjustment of small-stock portfolios is not slower than that of large-stock portfolios. Additionally, limited evidence supports a positive leading role of large-stock portfolio returns over small-stock portfolio returns. These two findings are substantially different from the results of previous research on developed markets.     

They're not employees, they're people

In this essay, business thinker Peter Drucker examines the changing dynamics of the workforce--in particular, the need for organizations to take just as much care and responsibility when managing temporary and contract workers as they do with their traditional employees. Two fast-growing trends are demanding that business leaders pay more attention to employee relations, Drucker says. First is the rise of the temporary, or contract, workers; 8 million to 10 million temp workers are placed each day worldwide. And they're not just filling in at reception desks. Today, there are temp suppliers for every kind of job, all the way up to CEO. Second, a growing number of businesses are outsourcing their employee relations to professional employee organizations (PEOs)--third-party groups that handle the ever mounting administrative tasks associated with managing a company's employees. (Managers can easily spend up to one-quarter of their time on employee-related rules, regulations, and paperwork.) Driving these trends, Drucker observes, is the shift from a dependency on manual labor to create wealth and jobs to a dependency on specialization and knowledge. Leaders are increasingly trying to keep up with the needs of many small groups of product or service experts within their companies. Temps and PEOs free up leaders to focus on the business rather than on HR files and paperwork. But if organizations outsource those functions, they need to be careful not to damage relationship with their people in the process, Drucker concludes. After all, developing talent is business's most important task--the sine qua non of competition in a knowledge economy.     

The moderating influence of strategic orientation on the strategy formation capability–performance relationship

An effective strategy formation capability is a complex organizational resource—a dynamic capability that should lead to superior performance. Strategy scholars have examined the strategy formation capability from many perspectives. However, no study has examined a comprehensive model of strategy formation in the context of the firm's strategic orientation. We develop and examine such a model. The results show that strategic orientation moderates the relationship between different elements of the strategy formation capability and performance. Copyright © 2006 John Wiley & Sons, Ltd.
