Mueller, M.B. (2019, in press). The impact of worklife on male and female executives’ psychological health. Organization Development Journal.

This quantitative study surveyed N=481 senior executives to explore gender differences in the relationship between senior executives’ worklife and their subjective well-being as an indicator of their physical and cognitive performance. Results show significant differences between female and male senior executives in the profiles of seven worklife factors in terms of their relationship with subjective well-being. Therefore, the seven factors should be taken into consideration for organizational design as well as executive training and development programs.


Mueller M.B. (2019. Show me the money: Towards a model for a cost-benefit analysis of employee engagement interventions. International Journal of Organization Theory & Behavior, Volume 22, Issue 2.

This research contributes the first economic model for employee engagement interventions. The Economic Value Added (EVA) model allows for detailed cost/benefit analyses such as return on investment (ROI) calculations as a basis for executive decision-making. The EVA model is tested in a real life situation with 387 employees of a European pharmaceutical company. The test case yielded an ROI of 148.5% for the first twleve months on a specific organizational training and devleopment intervention.


Mueller M.B., Lovell G.P. (2018) Gender difference in the psychology of senior executives: Is it different at the top? Management and Economics Research Journal, Volume 4.

This quantitative study (1) investigated the relationship between basic psychological need satisfaction (BPNS) at work and subjective well-being (SWB) in 142 senior executives as indicator of their physical and cognitive performance and (2) compared the results to two other managerial level samples of 260 managers and 445 employees. The findings contribute new theoretical perspectives of differences in the relationship between BPNS at work and SWB by managerial level and senior executives’ gender (‘complementarity effect’). The findings can have a significant impact on organizational design, training and development measures.


Menize, A., Rune, K.T., Mueller, M.B., & Lovell, G.P. (2017). Using technology to enhance self-regulation of eating behavior. Journal of  Food & Nutritional Disorders, Volume 6, Issue 3.

The increasing prevalence of overweight and obesity has become a serious health problem impacting nearly a third of all people in the developed world. Negative health outcomes associated with being overweight or obese include increased risk of cardiovascular disease, Type 2 diabetes, and some forms of cancer. A commonly accused and suspected villain responsible for recent increases in obesity and decreased physical activity is technology, particularly screen-time. We argue that society needs to embrace technology, not fight it, to successfully manage future global obesity and health issues. To this end, this current research evaluates how an iPhone app could help support peoples’ attempts to manage their eating behavior; specifically, adhering to one’s diet despite the lure and temptation of our toxic food environment.


Lovell G.P., Gordon J.A.R., Mueller M.B., Mulgrew K. & Sharman R. (2015). Satisfaction of basic psychological needs, self-determined exercise motivation, and psychological well-being in mothers exercising in group-based versus individual-based contexts. Health Care for Women International, August 2015.

Motherhood is a complex and often a challenging transition period for women including hormonal changes, social changes including increased social isolation, loss of identity, actual and perceived negative changes in body image, role overload, weight retention, changes in sleep patterns, fatigue, and variation of daily routine. With these challenges and changing roles, depression during and after pregnancy is a major issue. While exercise is often lauded as an effective tool for enhancing psychological well-being and reducing the psychosocial impact of challenges faced by mothers, the mechanisms by which exercise helps and how to supports mothers’ motivation to exercise is not well understood. Our research into how mothers’ exercise contexts relate to their motivation to exercise, as well as psychological outcomes, was with the intention that our findings would help practitioners better design exercise programs to more successful facilitate exercise adherence and ameliorate the challenges of motherhood


Mueller, M.B. (2015). Mut zur Veränderung. Lichtblick - Journal für praktizierte Individualpsychologie, Special Edition IP Forum 2015, Seite 4-5.

This article reviews ‚change’ from an evolutionary perspective suggesting ‘courage’ as a link between ‘change’ and ‘well-being’. The mental vitamins of autonomy (vitamin A), belonging (vitamin B), and competence (vitamin C) are suggested as motivators for courage and as a tool for coaching and training.


Mueller, M.B., & Lovell, G.P. (2015). Theoretical constituents of relatedness need satisfaction in senior executives. Human Resource Development Quarterly, Volume 26, Issue 2.

Senior executives are the key organisational decision makers whose actions have a material impact on organizations and society. Apart from provoking claims by newspapers and business magazines, there is very little academic evidence to either support or reject claims that senior executives were greedy, short-term-oriented oligarchs only pursuing their self-interest. This qualitative study explored the theoretical constituents of relatedness need satisfaction, suggested by literature as a predictor of individuals’ motivation, behavior, performance, and well-being. The theoretical constituents could be addressed by executive development programs to raise senior executives’ effectiveness as a key contributor to organizational performance and societal welfare.


Mueller, M. B., & Lovell, G.P. (2013). Relatedness need satisfaction in senior executives. European Journal of Business and Social Sciences, Volume 2, Issue 7, 105-135.

Academic studies have identified senior executive actions as a predictor of corporate functioning, behavior, and performance. Hambrick et al. (2005) suggest that senior executives are “finite flawed human beings” who “reside in jobs where the stakes associated with their humanness – both positive and negative – are enormous” (p. 503). For example, the 2008 financial crisis has been proposed by literature, at least in part, to be a result of senior executives’ actions related to negative aspects of humanness such as unethical behavior. Given the potentially far-reaching negative implications of senior executives’ behavior for organizations and society, this research examined senior executives’ inner lives, specifically relatedness need satisfaction in senior executives’ as antecedent of their behavior.

We are not proposing senior executives as the source of all dysfunctional, organizational developments Instead we suggest that there is a strong need to monitor senior executives’ psychological well-being from a corporate risk management point of view and to support senior executives to function efficiently not only for the benefit of themselves, but also in terms of their influential role within society. Our model is intended to provide a framework for the direction of future research as well as the development of programs, interventions, and monitoring tools. Effective corporate governance strategies that help better monitor and manage senior executives’ self-regulation challenges have the clear benefit of contributing to individual, organizational, and social welfare.


Kraeussl, R., Lehnert, T., Martelin, N. (2016). Is there a bubble in the art market? Journal of Empirical Finance, 35, 99-109

Record-breaking prices in the art market raise the question of whether we are experiencing a speculative bubble. Defining a bubble is not a straightforward process. In this study, we apply a new statistical test that looks at how « explosive » prices are over time. We study six different art market segments for the period from 1970 to 2014 and identify two historical speculative bubbles. We also find an explosive movement in today's “Impressionist and Modern”, “Post-war and Contemporary”, “American”, and “Old Masters” fine art market segments.


Lehnert, T., Yuehao, L., Martelin, N. (2016). Stein's overreaction puzzle: Option anomaly or perfectly rational behavior? The Journal of Derivatives, 23(3), 22-35

An option is a financial instrument whose value depends on the value of an underlying asset. Options come with different maturity (expiration) dates. In the late 80s, Stein (an economist from Harvard) looked at the relationship between implied volatilities of options of different maturities. He found out that implied volatility of longer maturity (two- months) options did not move in a smoothing manner to changes in implied volatility of shorter maturity (one-month) options. He called that an anomaly because it contradicted what theory had predicted. We show in this study that investors’ risk aversion appears to be the main factor driving this persistence.
