Applying a systems approach to human resource management

One reason why organizational improvement efforts often fall short of expectations is that they are rarely systematic. This article describes both the theory and practice of improving human resource management (HRM) using an example from McDonnell Douglas Corporation, in which an integrated systems approach was applied. A model of various, specific HRM initiatives is presented. The plan for undertaking these initiatives is also described. A key factor in the success of this approach is in changing the mental models that executives hold regarding how organizations really function. A major part of this shift is appreciating that organizational improvement initiatives are not additive but interactive. © 1999 John Wiley & Sons, Inc.     

Medical Insurance Coverage and Health Production Efficiency

Conventional economic theory predicts that medical insurance coverage causes an inefficient production of health because of  ex ante  and  ex post  moral hazard effects. However, no research has empirically examined the magnitude of the inefficiency. This study empirically examines the impact of medical insurance on the technical efficiency of health production at the metropolitan level. The underlying health production function allows for preventive care, curative care, and behavioral factors. Data envelopment analysis determines relative technical efficiency. The multiple regression results indicate that insurance coverage generates inefficiency but the efficiency loss appears to be relatively small on the extensive margin.     

Liquidity: Considerations of a Portfolio Manager

This paper examines liquidity and how it affects the behavior of portfolio managers, who account for a significant portion of trading in many assets. We define an asset to be perfectly liquid if a portfolio manager can trade the quantity she desires when she desires at a price not worse than the uninformed expected value. A portfolio manager is limited by both what she needs to attain and the ease with which she can attain it, making her sensitive to three dimensions of liquidity: price, timing, and quantity. Deviations from perfect liquidity in any of these dimensions impose shadow costs on the portfolio manager. By focusing on the trade-off between sacrificing on price and quantity instead of the canonical price-time trade-off, the model yields several novel empirical implications. Understanding a portfolio manager's liquidity considerations provides important insights into the liquidity of many assets and asset classes.     

Woman to women: Social marketing an idea to the new world

In 1971, Kotler and Zaltman developed a formal planning process for social marketing. But this article highlights the marketing of the idea of Britain's moral cause to American women in 1939–41, a clever example of social marketing thinly disguised to avoid the abhorrence attached to propaganda. The authors show how Ruth Drummond's letters in Ladies' Home Journal contain an effective mix of communication elements dedicated to winning women to a way of thinking that they had rejected initially. © 1998 John Wiley & Sons, Inc.     

The implication of discount rate changes for market timing

This study implements and tests a market timing trading rule using the public information contained in discount rate changes as signals to enter or exit the stock market. The trading rule entails entering the market on an initial discount rate cut and remaining fully invested through any subsequent cuts. Alternatively, an initial discount rate increase signals an exit from the market and remaining out of the market through any subsequent increases. It is presumed that short-term Treasury instruments are held in out-market periods. We test and report the results of this market timing strategy in comparison to a benchmark buy-and-hold strategy through the use of various investment performance measures. Analysis of ex-post returns indicates that the market timing trading rule produces higher risk-adjusted returns than a buy-and-hold-the-market strategy. Even without a risk adjustment, the returns of the strategy exceed those of the passive buy-and-hold strategy in the three subperiods analyzed. The strategy's predictive accuracy for timing the market clearly exceeds the minimum predictive accuracy suggested by earlier market timing literature. Finally, the results of the statistical analysis indicate that the strategy is successful in outguessing the market as defined in the classical Treynor and Mazuy illustration.     

Downsizing and the hyper-effective manager: The shifting importance of managerial roles during organizational transformation

This article describes how managerial roles change in importance during periods of significant organizational transition. An interdisciplinary approach reveals that (1) the competing values framework is a useful framework for examining this question; (2) the transformational roles increase as expected during downsizing; (3) three of four transactional roles also increase during downsizing. This last counterintuitive finding is illuminated by the interdisciplinary model developed. Overall, managers show significant evidence of hyper-effectivity—a state of high performance that is likely to be unsustainable in the long term. Implications for human resource practitioners and researchers are discussed. © 1996 by John Wiley & Sons, Inc.     

Beyond property: Rural politics and land‐use change in the Colombian sugarcane landscape

Analysing the sugarcane landscape in the flat valley of the Cauca River (Colombia) reveals that agricultural industrialization in the region required the concentration of land use by regional industrialists and the corresponding exclusion of landowners and poor peasants from territorial decision‐making processes. The analytical lens used in this article, based on the use and control over land and land‐based natural commons, allows for the characterization of three periods in a non‐linear process of articulation and dispute between poor peasant and capitalist agents in the expansion of the sugarcane monoculture during the 20th century. The different constellations of social agents, governmental nexus, and capital enclosures have enacted through mechanisms that, beyond concentrating land property, have managed to deprive rural ethnic communities from their cultural and environmental heritage, traditional economies, and possible futures.     

An analysis of Australian exchange traded options and warrants

This study focuses on the price discovery process in Australian option and warrant markets. Characterizing these two markets in terms of their cost structures and institutional features, we formally test competing price discovery hypotheses. The general findings indicate that the warrants market is the dominant market suggesting that their lower trading cost outweigh their less attractive institutional features. Additionally, we find that idiosyncratic differences among firms may result in a clientele effect thus providing justification for the coexistence of these seemingly redundant markets.     

Creating new growth platforms

Sooner or later, most companies can't attain the growth rates expected by their boards and CEOs and demanded by investors. To some extent, such businesses are victims of their own successes. Many were able to sustain high growth rates for a long time because they were in high-growth industries. But once those industries slowed down, the businesses could no longer deliver the performance that investors had come to take for granted. Often, companies have resorted to acquisition, though this strategy has a discouraging track record. Over time, 65% of acquisitions destroy more value than they create. So where does real growth come from? For the past 12 years, the authors have been researching and advising companies on this issue. With the support of researchers at Harvard Business School and Insead, they instituted a project titled "The CEO Agenda and Growth". They identified and approached 24 companies that had achieved significant organic growth and interviewed their CEOs, chief strategists, heads of R&D, CFOs, and top-line managers. They asked, "Where does your growth come from?" and found a consistent pattern in the answers. All the businesses grew by creating new growth platforms (NGPs) on which they could build families of products and services and extend their capabilities into multiple new domains. Identifying NGP opportunities calls for executives to challenge conventional wisdom. In all the companies studied, top management believed that NGP innovation differed significantly from traditional product or service innovation. They had independent, senior-level units with a standing responsibility to create NGPs, and their CEOs spent as much as 50% of their time working with these units. The payoff has been spectacular and lasting. For example, from 1985 to 2004, the medical devices company Medtronic grew revenues at 18% per year, earnings at 20%, and market capitalization at 30%.     

Resource use in patients hospitalized with complicated skin and soft tissue infections in Europe and analysis of vulnerable groups: the REACH study

Background:

Hospitalized patients with complicated skin and soft tissue infections (cSSTI) present a substantial economic burden, and resource use can vary according to the presence of comorbidities, choice of antibiotic agent, and the requirement for initial treatment modification. REACH (NCT01293435) was a retrospective, observational study aimed at collecting empirical data on current (year 2010–2011) management strategies of cSSTI in 10 European countries.

Methods:

Patients (n?=?1995) were aged ≥18 years, hospitalized with a cSSTI and receiving intravenous antibiotics. Data, collected via electronic Case Report Forms, detailed patient characteristics, medical history, disease characteristics, microbiological diagnosis, disease course and outcomes, treatments before and during hospitalization, and health resource consumption.

Results:

For the analysis population, mean length of hospital stay (including duration of hospitalizations for patients with recurrences) was 18.5 days (median 12.0). Increased length of hospital stay was found for patients with comorbidities vs those without (mean?=?19.9; [median?=?14.0] days vs 13.3 [median?=?8.0] days), for patients with methicillin-resistant Staphylococcus aureus compared with patients with methicillin-sensitive S. aureus (mean?=?27.7 [median?=?19.5] days vs 18.4 [median?=?13.0] days) and for patients requiring surgery (mean?=?24.4 [median?=?16.0] days vs 15.0 [median?=?11.0] days). Patients requiring modification of their initial antibiotic treatment had an associated increase in mean length of hospital stay of 10.9 days (median?=?6.5) and additional associated hospital resource use. A multivariate analysis confirmed the association of nosocomial infections, comorbidities, directed treatment, recurrent infections, diabetes, recent surgery, and older age (≥65 years), with longer hospital stay.

Conclusions:

This study provides real-life data on factors that are expected to impact length of hospital stay, to guide clinical decision-making to improve outcomes, and reduce resource use in patients with cSSTI.
