Housing tenure and labor market impacts: The search goes on

We develop two search-theoretic models emphasizing firm entry to examine the Oswald hypothesis, the idea that homeownership is linked to inferior labor market outcomes, and compare their predictions to three extant theories. The five models have surprisingly different predictions about the labor market at both the aggregate and micro levels. Using a suitable instrumental variable strategy, we estimate both micro and aggregate level regression models of wages and unemployment and compare the estimates to those predictions. We find that while homeowners are less likely to be unemployed, they also have lower wages, all else equal, compared to renters. In addition, higher regional homeownership rates are associated with a greater probability of individual worker unemployment and higher wages. The outcome of a horserace between our new search-theoretic models is mixed—the wage-posting model predicts observed unemployment impacts while a bargaining variant does a better job explaining observed wages and aggregate labor market outcomes. Overall, we conclude that firm behavior is important for understanding the labor market impacts of homeownership. Because this is the case, regional homeownership rates are not good instruments for individual tenure choice in empirical work. And while individual homeowners may have inferior labor market outcomes as compared to renters, from the viewpoint of society, higher homeownership rates may result in greater job creation and overall production, among other benefits.     

Gender diversity and firm performance: evidence from Dutch and Danish boardrooms

Drawing on the business case for gender diversity, this article examines whether board gender diversity has a positive effect on firm performance, based on evidence from the Netherlands and Denmark. We use empirical data on 186 listed firms observed in 2007. Almost 40% have at least one woman in the boardroom. Within boards, the average share of women is only 5.4%. To investigate the impact of board gender diversity, two-stage least-squares estimation is applied, using Tobin’s Q as a measure of performance. Our findings indicate that on the basis of this data-set, there is no relation between board diversity and firm performance.     

A semantics-based method for clustering of Chinese web search results

Information explosion is a critical challenge to the development of modern information systems. In particular, when the application of an information system is over the Internet, the amount of information over the web has been increasing exponentially and rapidly. Search engines, such as Google and Baidu, are essential tools for people to find the information from the Internet. Valuable information, however, is still likely submerged in the ocean of search results from those tools. By clustering the results into different groups based on subjects automatically, a search engine with the clustering feature allows users to select most relevant results quickly. In this paper, we propose an online semantics-based method to cluster Chinese web search results. First, we employ the generalised suffix tree to extract the longest common substrings (LCSs) from search snippets. Second, we use the HowNet to calculate the similarities of the words derived from the LCSs, and extract the most representative features by constructing the vocabulary chain. Third, we construct a vector of text features and calculate snippets’ semantic similarities. Finally, we improve the Chameleon algorithm to cluster snippets. Extensive experimental results have shown that the proposed algorithm has outperformed over the suffix tree clustering method and other traditional clustering methods.     

Reconstructing british rail: In search of a profitable railway

The objective of a profitable British Rail might be achieved by a segregation of its operating services and its permanent way (infrastructure). In the absence of a system of road pricing, only the operating services have the potential to be profitable. A segregation of railway operating services and infrastructure is also supported by an examination of fundamental characteristics of all modes of transport. While operating services exhibit the characteristics of competitive markets, infrastructure tends to monopoly. The reconstruction of British Rail in this way would improve the provision of transport services, by allowing competitive market pressures to be exerted more fully.     

In search of relevance: Project management in drifting environments

It can be assumed that projects are designed to produce relevant outcomes. However, it cannot be assumed that originally intended outcomes will necessarily remain relevant over time. This article explores the challenges to project management that stem from the possibility of relevance becoming eroded in the course of implementation. Relevance can become eroded when the environment of a project starts drifting. This may happen if, for example, customers change their preferences, competitors their strategies or corporate management their commitments. Alternative strategies for coping with drifting environments are discussed.     

In search of one set of categories

A method is described for transferring the categories as developed by several raters on the basis of the answers given to open-ended questions to one set of categories. This set covers all possible answers in an adequate way.     

In search of efficient network structures: the needle in the haystack

Searching for efficient networks can prove a very difficult analytical and even computational task. In this paper, we explore the possibility of using the genetic algorithms (GA) technique to identify efficient network structures in the case of non-trivial payoff functions. The robustness of this method in predicting optimal networks is tested on the two simple stylized models introduced by Jackson and Wolinsky (1996), for which the efficient networks are known over the whole state space of the parameters’ values. This approach allows us to obtain new exploratory results in the case of the linear-spatialized connections model proposed by Johnson and Gilles (Rev Econ Des 5:273–299, 2000), for which the efficient allocation of bilateral connections is driven by contradictory forces that push either for a centralized structure around a coordinating agent, or for only locally and evenly distributed connections.

Socio-economic constraints on Jamaica''s stabilization efforts: the importance of supply-side programs

Recently, there has been considerable interest in alternative stabilization programs in developing countries. This paper examines the possibility of implementing this type of program in a country that traditionally has had considerable difficulty in complying with International Monetary Fund programs. The macro-economic simulations of Jamaica's economy clearly show that successful supply-side policies could have mitigated the adverse income effects of stabilization associated with the standard IMF approach to stabilization.     

In search of management development in Europe: from self-fulfilling prophecies to organizational competence

This paper gives an overview and a critical analysis of the concept of High Flyer programmes in management development. Based on a discussion of the need for management development in modern knowledge- and service-based organizations, strengths and weaknesses of traditional management development programmes are discussed. In particular, the so-called ‘fast-track’programmes for high-potential employees are presented. This analysis shows that, although management development is supposed to be a vital contributor to organizational competence, learning, and change, High Flyer Programmes are (still) mainly an instrument for individual and personal career development. An alternative interpretation of management development is presented which emphasizes the match between personal growth and organizational learning and which links career, organization development and competitive advantage of the organization. In conclusion, implications for practice and research are discussed.

Quantitative results from the most recent Cranfield Network on European HRM Survey are presented and analysed.

In search of rationality: the purposes behind the use of formal analysis in organizations.

This paper describes the results of a study that examines how formal analysis is actually used in practice in three different organizations. Four main groups of purposes for formal analysis--information, communication, direction and control, and symbolic purposes--are identified and related to the nature of the social and hierarchical relationships between those who initiate analysis, those who do it, and those who receive it. It is concluded that, far from being antithetical as often assumed, formal analysis and social interaction are inextricably linked in organizational decision making and that different structural configurations may generate different patterns of use of analysis.     

In search of content validity: facet analysis as a qualitative method to improve questionnaire design

In this paper, two scales are examined for the measurement of self-regulation. The item content is evaluated for its specific usefulness for measuring self-regulation of obesity patients. Qualitative facet analysis (QFA), an application of Guttmann’s Facet Theory, is used to investigate whether item content sufficiently covers the intended content area. This form of content analysis constitutes a systematic, effective and critical tool for improving the content validity of questionnaires. It discovers topics that are underrepresented or overrepresented. The method offers a way to clarify the relationship between concrete item phrases and the desired content as defined by construct and theory. It allows the researcher to improve his or her understanding of the items as a stimulus and of the similarities of items, and allows the formulation of a possible structure for confirmative factor analysis. Various ways to improve the content of both scales are identified.     

Project‐as‐practice: In search of project management research that matters

Research on projects is not only an immature field of research, but it is also insubstantial when it comes to understanding what occurs in projects. This article contributes to making project management research matter to the academic as well as to the practitioner by developing a project‐as‐practice approach, in alignment with the ongoing debate in social science research. The article outlines a framework and argues that there are two major challenges to the researcher and also suggests how these challenges can be met. Underlying notions of the practice approach are outlined to ensure a development of the project‐as‐practice approach that makes project management research matter!

In search of a kingdom: Determinants of subsequent career outcomes for chief executives who are fired

Research on forced CEO succession has focused on determinants of exit, impact on the organization, or implications for the incoming CEO. Generally unexamined is what happens to the ousted CEO. Using a sample of 60 forced exits from the Business Week 1000 from 1988 to 1992, this study seeks to identify factors which influence the career outcomes for the ousted CEO. The study found that age matters—older CEOs were less likely to obtain other active executive positions, but were more likely than younger ousted CEOs to enter advisory roles. Further, the reason for the CEO's exit had a significant impact on the likelihood of subsequently assuming either an active or an advisory role. No relationship was found between career outcomes and the following: media coverage, levels of compensation at exit, board memberships. © 1995 by John Wiley & Sons, Inc.
