A century of corporate takeovers: What have we learned and where do we stand?

This paper reviews the vast academic literature on the market for corporate control. Our main focus is the cyclical wave pattern that this market exhibits. We address the following questions: Why do we observe recurring surges and downfalls in M&A activity? Why do managers herd in their takeover decisions? Is takeover activity fuelled by capital market developments? Does a transfer of control generate shareholder gains and do such gains differ across takeover waves? What caused the formation of conglomerate firms in the wave of the 1960s and their de-conglomeration in the 1980s and 1990s? And, why do we observe time- and country-clustering of hostile takeover activity? We find that the patterns of takeover activity and their profitability vary significantly across takeover waves. Despite such diversity, all waves still have some common factors: they are preceded by technological or industrial shocks, and occur in a positive economic and political environment, amidst rapid credit expansion and stock market booms. Takeovers towards the end of each wave are usually driven by non-rational, frequently self-interested managerial decision-making.     

A Puzzle in SRI: The Investor and the Judge

As Socially Responsible Investment (SRI) enters the mainstream of professional and institutional investment practice, some perplexities arise. Some SRI market participants are well schooled in finance but are hesitative as to how to apply non-financial criteria in the management of portfolios. Governments too are giving SRI more attention and, in some countries, are discussion whether and how to regulate the SRI market. Advocacy groups are targeting SRI projects through media campaigns using political discourse. Many of the pertinent questions that come with these perplexities are of the philosophical or ethical type and concern legitimisation, demarcation of responsibilities, interpretation of norms and policy formulation. The inclusion of non-financial criteria into investment decision-making leads to a ‹puzzle in SRI’ for which this article offers a solution. The puzzle arises when the day-to-day implementation of an SRI-policy coincides with the process of administering justice. Three questions make up that puzzle: (1) what should an␣investor do when allegations arise about a corporation, (2) what should an investor do when a corporation is brought before a court, (3) what should an investor do when a corporation is found guilty by a court. This article argues, by distinguishing between the rationality of the investor and that of the judge, that allegations, court cases or court verdicts should not be reasons to disinvest from a corporation. This article offers examples from investor practice and points out in which way allegations, court cases and court verdicts make sense for investor behaviour.     

Scalability and robustness of a network resource allocation system using market-based agents

In this paper, we consider issues associated with scalability and robustness in designing a market-based multi-agent system that allocates bandwidth in a communications network. Specifically, an empirical evaluation is carried out to assess the system performance under a variety of design configurations in order to provide an insight into network deployment issues. This extends our previous work in which we developed an application that makes use of market-based software agents that compete in decentralised marketplaces to buy and sell bandwidth resources in a network that is partitioned into regions, each with a separate market server. We investigate the average call success rate and average message load per market server, as the number of markets are scaled up in a fixed size network. The same investigations are performed in the presence of single market failures. Finally, for both the failure and non-failure cases, a trade-off is found between their average call success rates and message load per server in order to find an optimum number of regions to deploy in the network.     

An empirical model of a household's choice of activities

This paper analyses how households of school-age children choose to participate in the labour force, volunteer work, democratic assemblies, and child-related leisure activities. Contrary to previous studies, the model presented in this paper treats all of these household's choice of activities involving time allocation decisions as simultaneously determined. The empirical section uses qualitative data estimation techniques which permit a wide range of joint and interaction effects among the variables of the model. The results confirm the importance of time-opportunity cost variables as major determinants of household's choice of activities with the mother's education consituting a particularly important factor.     

How relative income affects work hours preferences

In this article, we look at explanations for why people want to change their working hours. We focus on the role of income and differentiate between the effect of household income, personal income and self-perceived relative income. Using Flemish data on 1435 workers, we perform binary logistic regressions in which we compare those who are over- or underemployed with those who are currently working their preferred number of hours. Our results show that the desire to work fewer hours is mostly related to a bad work–life balance, while the wish to increase working hours is associated with relative income rather than absolute income. Based on our findings we recommend governments to not only focus on increasing flexibility at the individual level but to also consider these positional effects by taking measures (e.g. decreasing the duration of the standard working week) at the population level.     

SMEs' Radical Product Innovation: The Role of Internally and Externally Oriented Knowledge Capabilities

This study examines the role and contribution of specific internally (knowledge diversity and sharing capabilities) and externally oriented knowledge‐related capabilities (exploratory, transformative, and exploitative learning processes of absorptive capacity) to radical product innovation in small and medium‐sized enterprises (SMEs). It extends the current literature on the topic by considering both types of knowledge‐related capabilities and by hypothesizing and testing connections between both. Our path analysis results, based on a sample of 194 SMEs in dynamic environments, indicate that radical innovation is positively affected by exploitative learning and by the knowledge sharing capability. Implications and suggestions for future research are discussed.
