Research note and communication mergers that last: A predictable pattern?

This paper examines the current ownership of 434 large acquisitions made by publicly traded U.S. firms between 1967 and 1969. It is found that the majority of these acquisitions are still held by the acquiring firms. Unrelated acquisitions were resold at a moderately higher, though not significantly different, rate than related acquisitions. These results are discussed in the context of the commonly held view that unrelated acquisitions of that period were poorly conceived additions.     

Comparative Industrial Relations Research: Towards Reversing the Gender Bias

This paper seeks to begin the reversal of the gender bias in comparative industrial relations research which is still focused on comparing and contrasting the regimes that cover mainly male manual workers. There is little systematic evidence on industrial relations practices in private or even public services, for non-manual workers or for atypical workers. These employment areas are central for women's employment and are of increasing importance in the labour market, but few attempts have been made to compare industrial relations regimes by reference to the protection they afford to women. Taking into account industrial relations practice in these areas can change significantly the classification and estimated coverage of collective bargaining systems. By 'mainstrearning' gender issues it also becomes clear that current macroeconomic policy proposals have major gender implications that are ignored in current debates     

The sustainable growth model: A tool for evaluating the financial feasibility of market share strategies

Market share objectives constitute a key element of a firm's corporate strategy. Market share strategy decisions—to build, maintain, or harvest share—are generally based on a careful consideration of the long-term and short-term profitability and cash flow implications of such decisions. The product sales growth rate and capacity expansion implications of share building strategies, the sustainability of implied sales growth targets and its consistency with the established financial policies and objectives of the firm are the subject of this report. The sustainable growth model outlined provides a framework for evaluating the financial feasibility of sales growth objectives at the strategic business unit level and the firm level, from the standpoint of expected return on sales, investment requirements per dollar of sales, target capital structure and the dividend policy of the firm.     

Research notes and communications a note on global strategies

This article augments, as well as takes issue with, the recent review by Ghoshal on international competition. The central question is what changes strategically when a firm moves from domestic to overseas competition. In analyzing this question, it is shown that there exists a neglected line of relevant research by two schools of thought: the Cambridge (Massachusetts) axis and internalization theory. The recent focus of research is described as understanding the multinational corporation as a network competing on its flexibility and the transfer of acquired capabilities across borders.     

Research notes and communications management and organizational change: A note on the railroad industry

Hypotheses which relate top-level managers' age, years of company and industry service, and education to strategic change are studied with a sample of 855 managers from 27 railroads. Results generally support hypotheses that younger managers and those with less experience are more likely to alter their strategies with changing environmental conditions.

Path analysis of the relationship between market share,business-level conduct and risk

This study evaluated the impact of market share on three measures of business-level risk: ROI variation, share instability and the difference between growth in price and growth in cost. The analysis also included conduct variables which might bear upon these relationships. The sample was drawn from the PIMS data base and consisted of mature industrial businesses separated into three types of market environments. Path analysis was employed and yielded partial support for the risk-reduction benefits of market share.     

Market share inequality,the HHI,and other measures of the firm-composition of a market

Data for individual markets suggest that the Herfindahl- Hirschman Index does not fully account for the inequality of market shares and the number of firms in a market. An empirical investigation is conducted to determine whether share inequality, number of firms, and major firm presence affect market profit rates independent of the HHI. The analysis controls for efficiency, among other things. Test results based on 1,684 banking markets during 1990–1992 indicate that the HHI, market share inequality, and the importance of major firms are positively related and the number of firms is negatively related to profit rates. Results on several other variables also suggest that market imperfections exist in local banking markets.     

Auction cartels and the absence of efficient communication

This paper examines the feasibility of collusive mechanisms in single-unit auctions. A model is constructed with private and common value information asymmetry and continuous type space. We show that an incentive compatible bid coordination mechanism (BCM) does not exist if common value uncertainty is present. This result contradicts actual antitrust cases, where common effects or resale opportunities created uncertainty about valuations, but a price-fixing cartel was formed. We solve the puzzle by relaxing the assumption that all bidder types truthfully reveal their private information. The introduced Bayesian bid coordination mechanism (BBCM) exists if the main source of information asymmetry is private value. In that case, a designated ring member can signal high valuation and suppress competition. Our results demonstrate the rationale behind cartel mechanisms with pre-auction knockouts.

A note on the sensitivity analysis of the internal rate of return

In this note we discuss the sensitivity analysis of the internal rates of return (IRR). We show that the use of partial derivatives can be misleading in the identification of key drivers of an investment project's performance. To remedy this shortcoming, we propose the use of an alternative sensitivity measure called the Differential Importance Measure. The analysis shows that, even if the theoretical conditions for using the Net Present Value or the IRR as valuation criteria apply, the sensitivity analysis results for the two indicators may differ.     

Characterizing and comparing the evolution of the major global economies in information and communication technologies

In this paper, we characterise and compare status and evolution of the ICT industry of the six major global economies in ICT: China, the EU, Japan, Korea, Taiwan and the USA. For this, we employ official data covering the period 2006–2009. Our analysis shows that although the EU is the largest economy of the world, it is the least ICT-specialised economy of all six major ICT economies. The USA is clearly the top global player in ICT in many respects. In both ICT Manufacturing and ICT Services it has the largest Value Added, BERD, BERD intensity and labour productivity. We further observe that China has, by far, the largest number of employees in both ICT Manufacturing and Services, while its level of ICT BERD remains low. China is however an emerging economy and economic indicators of its ICT sector have strongly grown from 2006 to 2009. Japan׳s ICT sector has a larger weight in the national economy than those of the USA, EU, and China. Moreover, it is the country from which the highest number of ICT patent applications originate. We also find that, of all six major global economies in ICT, Taiwan and Korea have the most ICT-specialised economies, with a strong orientation towards Manufacturing. Finally, we discuss selected results of our analysis and conclude the paper with tentative policy implications for the EU.     

Consequences of the shifts in U.S. Research and Development policy

This paper is an edited version of a talk given in Copenhagen, Denmark on June 19, 1984 on a panel on public policy at the 26th international meeting of The Institute of Management Sciences (TIMS). The talk deals with the consequences of the recent marked shifts in the research and development policy of the U.S. government, as seen by the top federal science and technology administrator in three major areas: defence, aeronautics and space, and energy. Collectively they put the shifts into good perspective, see them in the main as being beneficial, and describe certain needed modifications to what in some respects have been evolving policies.

New new technologies: the future and the present of work in information and communication technology

This paper outlines a selection of technological and organisational developments in the information and communication technology (ICT) sector and analyses their likely challenges for workers and trade unions around the globe. It addresses the convergence of telecommunications and information technology, the related developments of ubiquitous computing, ‘clouds’ and ‘big data’, and the possibilities of crowdsourcing and relates these technologies to the last decades' patterns of value chain restructuring. The paper is based on desk research of European and international sources, on sector analyses and technology forecasts by, for instance, the European Union and Organisation for Economic Co‐operation and Development, and some national actors. These prognoses are analysed through the lens of recent research into ICT working environments and ICT value chains, identifying upcoming and ongoing challenges for both workers and unions, and outlining possible research perspectives.
