Lean remains popular in a wide range of private and public sectors and continues to attract a significant amount of research. However, most of this research is not grounded in theory. This paper presents and discusses different expert viewpoints on the role of theory in lean research and practice and provides guidelines for future research.

Seven experienced lean authors independently provide their views to the question “is Lean a theory?” before Rachna Shah summarizes the viewpoints and provides a holistic outlook for lean research.

Authors agree, disagree and sometimes agree to disagree. However, a close look reveals agreement on several key points. The paper concludes that Lean is not a theory but has plenty of theoretical underpinnings. Many lean-related theories provide promising opportunities for future research.

As researchers, we are asked to justify our research drawing on “theory,” but what does that mean for a practice-driven phenomenon such as lean? This paper provides answers and directions for future research.

The purpose of this paper is to identify the main determinants of foreign direct real estate investments (foreign direct investment (FDI)) in selected Middle Eastern and North African (MENA) countries.

The empirical work of this study is an econometric analysis of FDI in the commercial real estate sector for eight MENA markets, namely Algeria, Egypt, Morocco, Qatar, Saudi Arabia, Turkey, Tunisia and the UAE during the period 2003-2009. The econometric analysis is carried out using the pooled Tobit model technique for panel data.

The paper finds that both country-specific factors and real estate sector-specific variables consistently support hypotheses explaining commercial real estate-related FDI, and find evidence that political stability explains why some selected MENA countries attract more real estate investments than other MENA countries.

The findings should be seriously considered in any policy making effort on the part of governments in the region.

The authors contribute to the existing literature in many ways. First, the study aims to develop econometric models, using both conventional and unique variables, to be generalised and applied to any developed or emerging market. The study applies relevant techniques in estimating the models, including the pooled Tobit model. Second, the research studies eight selected MENA real estate markets from 2003 to 2009, a timeframe and geography not examined in previous published empirical work on commercial real estate investments. Lastly, and for the first time in real estate literature, the study applies the location dimension of Dunning’s OLI paradigm as a theoretical explanation for the behaviour of foreign investors in commercial real estate towards the selected MENA markets.

Trust involves making oneself vulnerable to another person with the prospect of receiving some benefit in return. Contemporary theoretical accounts of trust among strangers emphasize its instrumental nature. People are assumed to trust to the extent that they can tolerate the risk and are sufficiently optimistic that their trust will be reciprocated. We describe evidence from laboratory economic games showing that this account empirically fails. Participants often trust even though their risk tolerance and social expectations suggest they should not. We propose, instead, that trust is largely an expressive act. People trust because of dynamics that surround the act itself rather than its potential outcomes. Evidence for the expressive nature of trust comes in two forms. First, studies of the emotions surrounding trust indicate that it is significantly predicted by how people feel about the act itself, not how they feel about its potential outcomes. Second, trust rates rise significantly if people are placed in a relationship with another person, no matter how anonymous, fleeting, or minimal that relationship is – presumably because being placed in a relationship evokes social norms that promote trust. We end our discussion by explaining a curious fact that participants grossly underestimate the trustworthiness of others. We also discuss possible motives for reciprocating trust and questions for future research.

Structural equation modeling (SEM) has been widely used to examine complex research models in international business and marketing research. While the covariance-based SEM (CB-SEM) approach is dominant, the authors argue that the field’s dynamic nature and the sometimes early stage of theory development more often require a partial least squares SEM (PLS-SEM) approach. The purpose of this paper is to critically review the application of SEM techniques in the field.

The authors searched six journals with an international business (and marketing) focus (Management International Review, Journal of International Business Studies, Journal of International Management, International Marketing Review, Journal of World Business, International Business Review) from 1990 to 2013. The authors reviewed all articles that apply SEM, analyzed their research objectives and methodology choices, and assessed whether the PLS-SEM papers followed the best practices outlined in the past.

Of the articles, 379 utilized CB-SEM and 45 PLS-SEM. The reasons for using PLS-SEM referred largely to sampling and data measurement issues and did not sufficiently build on the procedure’s benefits that stem from its design for predictive and exploratory purposes. Thus, the procedure’s key benefits, which might be fruitful for the theorizing process, are not being fully exploited. Furthermore, authors need to better follow best practices to truly advance theory building.

The authors examined a subset of journals in the field and did not include general management journals that publish international business and marketing-related studies. Fur-thermore, the authors found only limited use of PLS-SEM in the journals the authors considered relevant to the study.

The study contributes to the literature by providing researchers seeking to adopt SEM as an analytical method with practical guidelines for making better choices concerning an appropriate SEM approach. Furthermore, based on a systematic review of current practices in the international business and marketing literature, the authors identify critical challenges in the selection and use of SEM procedures and offer concrete recommendations for better practice.

This paper seeks to offer a model on the evolution of the multinational business enterprise (MBE). It is meant to be an alternative to the eclectic paradigm, the preeminent theoretical tool applied in studies of the multinational enterprise (MNE) and foreign direct investment. The label MBE aims at moving focus from structure of production to change processes in business relations and entrepreneurship.

While the eclectic paradigm is grounded in neo-classical economics meant primarily to be applied in studies of macroeconomic interest and is based on assumptions not applicable in studies of individual firms, the model of the MBE is meant to be used in studies at the micro-level. It is rooted in assumptions consistent with behavioural theory consequently being more realistic. The model is based on the Uppsala model with input from studies on dynamic capabilities, entrepreneurship research and research on management under uncertainty.

The realistic assumptions of the model imply that it is relevant for understanding the dynamics of strategy and management of the MBE.

As the model aims at enriching our understanding of the dynamics of the MBE the paper recommends empirical longitudinal studies of firms.

Realistic and relevant assumptions imply that the model differs in critical respects from received theory in international business.

Front-line lean leadership is critical for implementing and sustaining lean production systems (LPS). The purpose of this paper is to analyze the relationships between front-line lean leader (FLL) capacities (cognitive, social, motivational, knowledge and experience), lean leader practices (developing people and supporting daily kaizen) and the degree of implementation of lean tools (pull system, involvement of employees and process control) in manufacturing companies.

A survey was conducted with FLLs from large Brazilian manufacturing companies. The survey collected 103 responses, 99 of which were validated. Data were analyzed using partial least squares structural equation modeling.

There was a positive, significant and direct relationship between FLL capacities, leadership practices and a degree of implementation of LPS tools on the shop floor. The validated model is a reference base for planning FLL capacities and practices that result in more effectively implementing LPS on the shop floor.

The findings provide managers with a new perspective on the importance of the development and training of FLLs focusing on leadership capacities. As decisions about developing lean capabilities impact the application of Lean leadership practices and the use of lean tools, they are also related to day-to-day lean activities and improved operational results. Additionally, the proposed model can be used by managers as a basis to diagnose, develop and select lean leaders.

This study seeks to fill a theoretical gap of knowledge on front-line lean leadership as it jointly addresses and empirically analyzes the existing relationships between lean leadership capacities, encompassing the perspective of psychology, lean practices and tools on the shop floor.

The complexity and uncertainty of healthcare operations increasingly require agility to safeguard a high quality of care. Using a microfoundations of dynamic capabilities perspective, this study investigates the effects of nurses' implicit voice theories (IVTs) on the behaviors that influence their individual agility.

This research uses quantitative survey data collected from 2,552 Canadian nurses during the fourth wave of the Covid-19 pandemic in the fall of 2021. Structural equation modeling is used to test a conceptual model that hypothesizes the effects of three different IVTs on nurses' creativity, spontaneity, agility and the quality of care they deliver to patients.

The results reveal that voice-inhibiting cognitions (like “suggestions are criticisms for higher-ups”, “I first need a solution or solid data”, and “speaking up has negative repercussions”) negatively impact nurses' creativity and spontaneity in crafting solutions to problems they face daily. In turn, this affects nurses' individual agility as they attempt to adapt to changing circumstances and, ultimately, the quality of care they provide to their patients.

Even if organizations have little control over employees' pre-held beliefs regarding voice, they can still reverse them by developing and nurturing a voice-welcoming culture to boost their workers' agility.

This study combines two theoretical frameworks, voice theory and dynamic capabilities theory, to study how individual-level factors (cognitions and behaviors) contribute to nurses' individual agility and the quality of care they provide to their patients. It answers the recent calls of scholars to study the mechanisms through which healthcare operations can develop and sustain dynamic capabilities, such as agility, and better face the “new normal”.

Internalization theory explains the existence and functioning of the multinational enterprise. It contributes to understanding the boundaries of the multinational enterprise, its interface with the external environment and its internal organizational design. Much work in the international strategic-management sphere has unfortunately not taken on board internalization-theory thinking and lacks the insights provided by this comparative institutional approach. In this chapter, we show how well-known international strategic-management models could be enriched and their normative implications altered by adopting an internalizing-theory lens.

I am honored to receive the Booz Allen Hamilton/strategy+business Eminent Scholar Award in International Management. I am even more honored to follow in the footsteps of such distinguished previous recipients of the AOM-IMD (Academy of Management-International Division) Distinguished Scholar Award as: John Child, Christopher Bartlett, Sumantra Ghoshal, John Dunning, and Yves Doz. Like them, I shall reflect here on my past contributions to scholarship, and then use this work as a building block for the major part of this paper, which is on the need for new and relevant theory in the field of international management.

The purpose of this paper is to examine the determinants of Greenfield emerging market (EM) outward foreign direct investment (OFDI) into the UK, a developed market (DM) host. Despite the increasing significance of EM OFDI, this particular theme of EM OFDI to a DM host has received relatively little attention from researchers. This paper seeks to address this shortfall.

Considering the distinctiveness of EM OFDI in its firm-specific characteristics, given circumstances and motivations, this paper applies adapted “Resource-based view (RBV)” framework and institutional theory to build a theoretical framework. A range of hypotheses regarding “strategic-asset seeking”, “market seeking” and “institution seeking” motivations of EM OFDI, which reflect both “pull factors” (advantages in hosts) and “push factors” (disadvantages at home), were then developed. Using panel data for the years 2003–2012, the research questions were analysed using a sample of the then most important EM source countries which had undertaken Greenfield FDI into the UK.

The analysis results supported the hypotheses that strategic-asset seeking and institution seeking motivations were important in determining EM OFDI to the UK, with the coefficients of relevant variables showing statistical significance and expected sign (i.e. positive). However, the hypothesis on market seeking motivation of EM OFDI cannot be supported as the coefficient of the relevant variable, whilst showing the expected sign, had a statistically insignificant coefficient. Amongst the three control variables, the source countries’ exports and imports as a percentage of GDP was statistically significant and had the correct sign whilst, the UK’s share of intra-EU trade, whilst statistically significant, had the opposite sign to that expected. The third control variable, the exchange rate was not statistically significant, though it had the correct sign.

This paper provides an adjusted theoretical framework for the analysis of EM OFDI to DM with a novel application of institutional theory and RBV. It also qualifies and extends existing works on EM OFDI by including a wider range of EM source countries and DM hosts with empirical analysis results as well as theoretical suggestions. In addition, the paper offers up a range of policy implications for DM hosts.
