The problem of unobservables in strategic management research

In this paper we argue that unobservable constructs lie at the core of a number of influential theories used in the strategic management literature—including agency theory, transaction cost theory, and the resource-based view of the firm. The debate over how best to deal with the problem of unobservables has raged in the philosophy of science literature for the best part of the current century. On the one hand, there are the positivists, who believe that theories containing unobservable constructs are only useful as tools for making predictions. According to positivists, such theories do not inform us about the deep structure of reality. On the other hand, there are the realists, who believe that our theories can give us knowledge about unobservables. Herein we review this debate, we argue for adopting a realist position, and we draw out the implications for strategic management research.

Construct measurement in strategic management research: illusion or reality?

Strategic management research has been characterized as placing less emphasis on construct measurement than other management subfields. In this work, we document the state of the art of measurement in strategic management research, and discuss the implications for interpreting the results of research in this field. To assess the breadth of measurement issues in the discipline, we conducted a content analysis of empirical strategic management articles published in leading journals in the period of 1998–2000. We found that few studies discuss reliability and validity issues, and empirical research in the field commonly relies on single‐indicator measures. Additionally, studies rarely address the problems of attenuation due to measurement error. We close with a discussion of the implications for future research and for interpreting prior work in strategic management. Copyright © 2004 John Wiley & Sons, Ltd.

Production Efficiency and Discriminatory Hiring Practices in the National Hockey League: A Stochastic Frontier Approach

This paper studies the production process in the National Hockey League (NHL) and attempts to identify the sources of production inefficiency, including potential inefficiencies associated with preferences for, or against French-Canadians. Employing the method of stochastic frontier estimation, it is shown that production inefficiencies are prevalent in the NHL and can, in part, be traced to differences in coaching ability, team ownership, local sports competition, and management experience. In addition, it is found that teams with unusually high (or low) numbers of French-Canadian players tended to be less efficient, implying that discriminating hiring practices are costly.Jel Classifications: D21, J71, L83     

Consequences of measurement problems in strategic management research: the case of Amihud and Lev

Strategic management research has been characterized as placing less emphasis on construct measurement than other management subfields. To illustrate the consequences of measurement error, we revisit the debate on the causes of diversification. Our research suggests that the divergent findings between studies on this topic are largely the result of measurement error, and that prior work has underestimated the true effect of size in the relationships between variables.

An assessment of the use of structural equation modeling in strategic management research

Structural equation modeling (SEM) is a powerful, yet complex, analytical technique. The use of SEM to examine strategic management phenomena has increased dramatically in recent years, suggesting that a critical evaluation of the technique's implementation is needed. We compared the use of SEM in 92 strategic management studies published in nine prominent journals from 1984 to 2002 to guidelines culled from methodological research. We found that the use and reporting of SEM often have been less than ideal, indicating that authors may be drawing erroneous conclusions about relationships among variables. Given these results, we offer suggestions for researchers on how to better deploy SEM within future inquiry. Copyright © 2004 John Wiley & Sons, Ltd.     

Use of partial least squares (PLS) in strategic management research: a review of four recent studies

Advances in causal modeling techniques have made it possible for researchers to simultaneously examine theory and measures. However, researchers must use these new techniques appropriately. In addition to dealing with the methodological concerns associated with more traditional methods of analysis, researchers using causal modeling approaches must understand their underlying assumptions and limitations. Most researchers are well equipped with a basic understanding of LISREL‐type models. In contrast, current familiarity with PLS in the strategic management area is low. The current paper reviews four recent studies in the strategic management area which use PLS. The review notes that the technique has been applied inconsistently, and at times inappropriately, and suggests standards for evaluating future PLS applications.

Sample selection bias and Heckman models in strategic management research

Research summary: The use of Heckman models by strategy scholars to resolve sample selection bias has increased by more than 700 percent over the last decade, yet significant inconsistencies exist in how they have applied and interpreted these models. In view of these differences, we explore the drivers of sample selection bias and review how Heckman models alleviate it. We demonstrate three important findings for scholars seeking to use Heckman models: First, the independent variable of interest must be a significant predictor in the first stage of a model for sample selection bias to exist. Second, the significance of lambda alone does not indicate sample selection bias. Finally, Heckman models account for sample‐induced endogeneity, but are not effective when other sources of endogeneity are present. Managerial summary: When nonrandom samples are used to test statistical relationships, sample selection bias can lead researchers to flawed conclusions that can, in turn, negatively impact managerial decision‐making. We examine the use of Heckman models, which were designed to resolve sample selection bias, in strategic management research and highlight conditions when sample selection bias is present as well as when it is not. We also distinguish sample selection bias, a form of omitted variable (OV) bias, from more traditional OV bias, emphasizing that it is possible for models to have sample selection bias, traditional OV bias, or both. Accurately identifying the type(s) of OV bias present is essential to effectively correcting it. We close with several recommendations to improve practice surrounding the use of Heckman models.

Economy size and performance: An efficiency analysis in the telecommunications sector

The existing empirical evidence on the relationship between economy size and performance has been inconclusive. This paper employs stochastic frontier analysis to estimate economic measures of efficiency for the telecommunications sectors of 139 economies and examine their relationship with economy size. Simultaneously, it controls for the effects of competition in telecommunications, privatization of state-owned providers, independent regulators, and the quality of political institutions on sector performance. The findings suggest that economy size has a positive but decreasing impact on sector performance. Small economies have an incentive to grow to improve sector performance, though larger size is not a sufficient condition for efficiency. Sector policy and the quality of polity may contribute significantly to sector performance.     

Evaluating the efficiency and productivity change within government subsidy recipients of a national technology innovation research and development program

This study analyzes the efficiency and productivity change within government subsidy recipients of a national technology innovation research and development (R&D) program. We examine 6,990 government‐sponsored, completed R&D projects during the last three performance follow‐up survey years from 2010 to 2012, and present a design of the sample of panel data to cope with the typical R&D performance time lag using a set of massive observations associated with completed R&D projects for the past 7 years from 2005 to 2011. In particular, data envelopment analysis is adopted to measure the efficiency and productivity change, which is measured in the Malmquist index. Parametric and nonparametric statistical tests are carried out to check for statistically significant differences among the characteristics regarding the types of government subsidy recipients. This study's major findings are as follows. First, during the entire period analyzed (2010–2012), there was a similar yearly pattern of statistically significant differences in the government subsidy means among the recipient types. In contrast, there were no obviously equivalent differences in the efficiency and productivity change. Second, the productivity had increased year on year, but the increments were reduced from year to year. Third, the productivity change was induced mainly by the Frontier‐shift, which indicates overall technology innovation progress, compared with the Catch‐up, which only indicates a simple increase in the efficiency. In particular, in this empirical analysis, the recipient types of ‘national laboratory’ and ‘large company’ had relatively larger sizes of government subsidies per project. However, the efficiency and productivity change of these types was not better than the others. This implies, therefore, that the government should control the ratio of the subsidy to the total R&D budget with an appropriate upper limit.

• I empirically evaluate the productivity change within a national technology innovation R&D program.
• I design a sample of panel data to cope with the typical R&D performance time lag using massive observations.
• There is no obvious relationship between the government subsidy size and R&D productivity change.
• Some particular types of government subsidy recipient are inferior in terms of R&D productivity change.
• It practically implies that the government should control the ratio of the subsidy to the total R&D budget.

Technical efficiency and use of information and communication technology in Spanish firms

The literature concerned with the relationship between performance and information and communications technology (ICT) is usually focused on the ICT investments. This paper shows that it is the level of use of ICT within organisations, with preference as regards the expenses of ICT, which is responsible for the effect on performance. A general sample of 2255 Spanish companies has been used. Firms’ performance is measured as technical efficiency, which is determined by a data envelopment analysis (DEA), in which special attention is paid to the problem of the outliers. Finally, the analysis of the level of use of ICT is focused on a key area of the organisations, the supply chain, which affects the technical efficiency of the firms analysed. Results show that there is evidence of a positive effect of the use of ICT on technical efficiency. This effect is especially notable at intensive use levels in activities related to operations/manufacturing, purchasing or sales.

Market Structure and Hospital Efficiency: Evaluating Potential Effects of Deregulation in a National Health Service

In this article we examine the potential effect of market structure on hospital technical efficiency as a measure of performance controlled by ownership and regulation. This study is relevant to provide an evaluation of the potential effects of recommended and initiated deregulation policies in order to promote market reforms in the context of a European National Health Service. Our goal was reached through three main empirical stages. Firstly, using patient origin data from hospitals in the region of Catalonia in 1990, we estimated geographic hospital markets through the Elzinga–Hogarty approach, based on patient flows. Then we measured the market level of concentration using the Herfindahl–Hirschman index. Secondly, technical and scale efficiency scores for each hospital was obtained specifying a Data Envelopment Analysis. According to the data nearly two-thirds of the hospitals operate under the production frontier with an average efficiency score of 0.841. Finally, the determinants of the efficiency scores were investigated using a censored regression model. Special attention was paid to test the hypothesis that there is an efficiency improvement in more competitive markets. The results suggest that the number of competitors in the market contributes positively to technical efficiency and there is some evidence that the differences in efficiency scores are attributed to several environmental factors such as ownership, market structure and regulation effects.     

Assessing farm performance by size in Malawi,Tanzania, and Uganda

Many Sub-Sahara African countries have long endured sluggish agricultural productivity growth and a farm structure dominated by smallholders. This prevailing structure has led to public policies focusing on access to land and its distribution as ways to boost agricultural supply. Drawing on data from the Living Standards Measurement Study–Integrated Surveys on Agriculture (LSMS-ISA) for three East African countries (Malawi, Tanzania, and Uganda), our purpose is to: test whether smaller farms in these countries are more productive than larger ones; examine how managerial performance varies with farm size; and assess how public policy may improve farm performance. We adopt the Random Parameters Stochastic Production Frontier model to estimate and then decompose Total Factor Productivity (TFP) across different farm size classes. In doing so, we test for possible measurement errors of farmer self-reported land area using Global Positioning System (GPS) data, and explore the imperfect factor markets hypothesis. The results show that across the three countries TFP is higher for smaller farms than for larger ones. Overall, managerial performance is low suggesting that programs designed to enhance managerial capacity would promote farm productivity across all sizes. Other policies are size specific. Access to agricultural input markets improves the productivity of the small farms, while greater spending on transportation infrastructure and extension services enhances the productivity of the large.     

Using meta‐analytic structural equation modeling to advance strategic management research: Guidelines and an empirical illustration via the strategic leadership‐performance relationship

This paper demonstrates how meta‐analysis can be combined with structural equation modeling (MASEM) to address new questions in strategic management research. We review this integration, describe its implementation, and compare findings from bivariate meta‐analyses, a direct‐effect structural equations model, and two mediating frameworks using data on the strategic leadership and performance relationship. Results drawn from 208 articles that collectively included data on 495,638 observations demonstrate the new insights available from MASEM while also suggesting a revision to conventional thinking on strategic leadership. Whereas some theories posit that boards of directors influence firm performance through monitoring and disciplining the top management team, MASEM provides more support for the view that boards mediate the top management teams' decisions. Implications for applying MASEM in strategic management are offered. Copyright © 2014 John Wiley & Sons, Ltd.     

Polychronicity in top management teams: The impact on strategic decision processes and performance of new technology ventures

This study focuses on polychronicity as a cultural dimension of top management teams (TMTs). TMT polychronicity is the extent to which team members mutually prefer and tend to engage in multiple tasks simultaneously or intermittently instead of one at a time and believe that this is the best way of doing things. We explore the impact of TMT polychronicity on strategic decision speed and comprehensiveness and, subsequently, its effect on new venture financial performance. Contrary to popular time‐management principles advocating task prioritization and focused sequential execution, we found that TMT polychronicity has a positive effect on firm performance in the context of dynamic unanalyzable environments. This effect is partially mediated by strategic decision speed and comprehensiveness. Our study contributes to research on strategic leadership by focusing on a novel value‐based characteristic of the TMT (polychronicity) and by untangling the decision‐making processes that relate TMT characteristics and firm performance. It also contributes to the attention‐based view of the firm by positioning polychronicity as a new type of attention structure. Copyright © 2010 John Wiley & Sons, Ltd.     

Stakeholder management as a predictor of CEO compensation: main effects and interactions with financial performance

We test the effects of stakeholder management on CEOs' salaries, bonuses, stock options, and total compensation. We also examine the extent to which the interaction of stakeholder management and financial performance determines compensation. Using a longitudinal database of 406 Fortune 1000 firms, our results suggest that stakeholder management is relevant to boards of directors when setting CEO compensation. Specifically, we found a significant, negative main effect of stakeholder management on CEO salaries. Further, we found that stakeholder management typically reduces the rewards CEOs may get for increasing levels of financial performance. In tandem, these results indicate that CEOs may jeopardize their personal wealth by pursuing stakeholder‐related initiatives. Copyright © 2005 John Wiley & Sons, Ltd.
