Exploring Portfolio Decision‐Making Processes*

Portfolio management is the set of activities that allows a firm to select, develop, and commercialize a pipeline of new products aligned with the firm's strategy that will enable it to continue to grow profitably over the long term. To appropriately manage the firm's new product portfolio, decisions must be made about which projects to fund, to what levels, at what point in time. Previous research has investigated portfolio management decisions as individually discrete decisions. Significant streams of research have investigated both project selection and project termination decisions. This research project shows, however, that portfolio decision making may be better understood if it is considered as an integrated system of processes that considers these decisions simultaneously, along with other decisions such as those to continue a project with reduced funding. Using in‐depth data from four diverse case studies, we use a grounded theory approach to develop a general model of how firms make new product portfolio decisions. According to the findings from these cases, effective portfolio decision‐making processes produce a portfolio mindset, focus effort on the right projects, and allow agile decision making across the portfolio's set of projects. Effective portfolio decision making is the result of the interaction between three types of decision‐making processes that managers use in making decisions: evidence‐, power‐, and opinion‐based. Being able to use each of these types of processes to make decisions depends upon having the data inputs that they require. Three domain‐based decision input‐generating processes (i.e., cross‐functional collaboration, practices of critical thinking, and practices of market immersion) are associated with making evidence‐based portfolio decisions. In addition, organizational politics produces the inputs that are associated with power‐based portfolio decision making, while managerial intuition is associated with opinion‐based portfolio decision making. Firm cultural factors, including trust, collective ambition, and leadership style, are associated with how these evidence‐, power‐ and opinion‐based processes are combined into an overall portfolio decision making process, and whether the firm's processes are more rational and objectively made, or more politically and intuitively made. The article presents propositions for how the decision‐making processes interact in their associations with decision‐making effectiveness.     

Worker Participation and Firm Performance: Evidence from Germany and Britain

The Freeman–Lazear works council/worker involvement model is assessed over two distinct industrial relations regimes. In non-union British establishments our measures of employee involvement are associated with improved economic performance, whereas for unionized plants negative results are detected. The suggestion is that local distributive bargaining can cause the wrong level of worker involvement to be chosen. Also consistent with the model is our finding that mandatory works councils do not impair, and may even improve, the performance of larger German establishments. Yet smaller plants with works councils under-perform, illustrating the problem of tailoring mandates to fit heterogeneous populations.     

Marketing and Organisational Innovations in Entrepreneurial Innovation Processes and their Relation to Market Structure and Firm Characteristics

This paper analyses the influence of marketing and organisational changes on the innovation process. Using data from the German community innovation survey 2007, two topics are investigated: First, we analyse whether firm and market characteristics trigger certain innovation strategies. Second, this paper investigates whether marketing and organisational innovations (MO innovations) are complementary to product and process innovations (PP innovations) or whether they are substitutes. Our results suggest that firms choose broad innovation strategies, which combine MO and PP innovations, if they have large internal resources and intermediate market power. We also find that marketing innovations make product and process innovations more successful.     

Firm Growth Under Sample Selection: Conditional <Emphasis>σ</Emphasis>-Convergence in Firm Size?

This paper tests the second, widely neglected implication of Gibrat’s law stating that the variance of firm size distribution increases over time. In contrast, learning models imply conditional σ-convergence in firm size. A unique data set of Austrian firms especially suited to account for sample selection effects is used to analyze the growth/size nexus of firms. The estimation results suggest that the predicted variance in firm size decreases only for firms of age 30 or below. For older age cohorts the hypothesis of a constant variance either cannot be rejected or increasing variances are found.     

Inter‐Firm Training Co‐ordination in Britain

This paper examines employer co‐operation in the provision of training. Such collective action has a long history in Britain, but has varied over time in extent and strength. It exists in a strong form in the German‐speaking countries, where employers’ organizations and chambers of commerce are a fundamental part of the training system. On the basis of new data, we argue that this form of training is important in the UK and has a positive effect on the quantity and quality of training. Case studies are presented on several examples of collective action — a local chamber of commerce, an industry‐wide employers’ organization, a group training association, a network of firms in a large company’s supply chain and a local consortium of big employers. Although such forms of organization have much to commend them, in the UK coverage is uneven and stability is fragile.     

Making the Processes of Designing Explicit Within an Information Technology Environment

In this paper, technology is described as involving processes whereby resources are utilised to satisfy human needs or to take advantage of opportunities, to develop practical solutions to problems. This study, set within one type of technology context, information technology, investigated how, through a one semester undergraduate university course, elements of technological processes were made explicit to students. While it was acknowledged in the development and implementation of this course that students needed to learn technical skills, technological skills and knowledge, including design, were seen as vital also, to enable students to think about information technology from a perspective that was not confined and limited to `technology as hardware and software'. This paper describes how the course, set within a three year program of study, was aimed at helping students to develop their thinking and their knowledge about design processes in an explicit way. An interpretive research approach was used and data sources included a repertory grid `survey'; student interviews; video recordings of classroom interactions, audio recordings of lectures, observations of classroom interactions made by researchers; and artefacts which included students' journals and portfolios. The development of students' knowledge about design practices is discussed and reflections upon student knowledge development in conjunction with their learning experiences are made. Implications for ensuring explicitness of design practice within information technology contexts are presented, and the need to identify what constitutes design knowledge is argued.     

A Two–Tier Wage Structure in a Nonunion Firm

This study examines the perceptions of nonunion workers in a permanent two–tier wage structure. Consistent with the predictions of equity and justice theories, low–tier employees are found to be more likely to perceive the wage structure as unfair, have lower pay satisfaction and organizational commitment, and report poorer worker–management relations than high– tier employees. These attitudes may make nonunion firms more vulnerable to certification campaigns since they are the same factors that have been repeatedly linked to employee intentions to vote for a union.     

Firm Survival in the Netherlands

The purpose of this paper is to examine whether the dynamics of industrial organization differ in the Netherlands from what has emerged as a Stylized Fact in other countries. Because the Netherlands has pursued a unique set of institutions and policies comprising what has become known as the Polder Model, the factors leading to firm failure may systematically differ from those in other countries. We address this question using a longitudinal database from Statistics Netherlands (CBS) that identifies over two thousand firms in manufacturing and then tracks their performance over time.     

Exclusion and Disarticulation: The Transport and General Workers' Union in the Road Haulage Industry, 1979–1998

The attrition of trade union organization and collective bargaining in the UK is accepted as having been a principal feature of industrial relations since 1980, but there is no general agreement as to the causes. This paper explores trade union disarticulation and exclusion in a 1979–98 study of the Transport and General Workers' Union Road Transport Commercial trade group, which organizes in the road haulage industry. It emphasizes the importance of the legal framework established by the Conservative government in inhibiting union power at a time of the ongoing restructuring of road haulage, providing companies with the opportunity and incentive to exclude trade union organization and fragment union bargaining power.     

Union Representation Elelctions and Firm Profitability

Union representation elections are associated with significant declines in firm profitability. In addition to the significant mean effect of union elections on the equity value of firms, there exists substantial variation in the magnitude of equity losses across individual election events. Cross-sectional variation in shareholder equity losses can be explained by the labor intensity of the firm, the size of the union wage premium and fraction of workers organized in "the firm's industry,." the presence or absencse of right-to-work lows in the state where the election is held, the member of workers covered in the representaion election, and the number of previous union representation election in the firm. The empirical results indiacte the equity losses are the greatest in industries where union wage gain are the highest and unionization rates are the largest, and in the most labor-intensive firms, independent of the size of the bargaining unit involved in the election. The latter result indicates the presence of union spillover effects.     

Unions and the Duration of Workers' Compensation Claims

This paper examines the effect of union status on workers' compensation claim duration in Canada. I find that unionized workers have shorter claims than nonunionized workers and that relatively little of this difference can be attributed to differences in worker or job characteristics. I interpret this as being consistent with a strong union effect that reduces union member's claim duration. Plausible explanations for this finding and directions for future research are also discussed.
