  • The power of preferences: productivity and stress in new teleworkers during COVID-19

    Georg D Blind, Stefania Lottanti von Mandach, Masahiro Kotosaka, David Chiavacci

    Social Science Japan Journal (Oxford University Press)  jyae017 ( 2 ) 241 - 259 2024.08

    Joint Work, Accepted,  ISSN  1369-1465

    　View Summary

    This study of teleworking during the COVID-19 pandemic avoids a common self-selection bias by controlling for preferences and whether the introduction of teleworking was voluntary or mandatory. In a survey (n = 1,500) conducted in December 2020, we inquired about working arrangements and agent preferences in January, April, and December 2020. Productivity levels initially did not significantly differ for newly teleworking individuals after correcting for age, gender, marital status, breadwinner and management roles, childcare gap, area, job type, and general awareness, but were negatively affected by a preference mismatch (PM; around −3pp) and cognitive dissonance (not going with one’s preference in spite of having a chance to do so, adding another −5pp). By December 2020, individuals with a PM lost as much as 9pp of their productivity levels, but the net effect for those in partially remote work was only about −2pp. Similarly, stress levels initially did not differ for newly teleworking individuals using largely the same controls as before. By December 2020, stress levels for individuals newly undertaking fully remote telework were significantly lower than for the control group of individuals with unchanged working arrangements, but the PM contributed significantly to higher stress levels.

  • When professionals become entrepreneurs: identity construction of lawtech startup founders in Japan

    Masashi Goto, Masahiro Kotosaka, Mari Sako

    Journal of Professions and Organization (Oxford University Press)   2024.04

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  20518803

    　View Summary

    How do professionals develop their identity when they become digital venture founders, and how does such identity affect their venture strategy? This article examines this understudied yet important question. The recent wave of digitalization has created opportunities for various professionals to participate in creating new firms. However, studies of professions and entrepreneurship to date have narrowly focused on professionals’ intrapreneurship efforts within professional service firms (PSFs). This inductive study of lawtech ventures in Japan examines the sources of Founder Social Identity (FSI). The study shows that founders’ professional role identity developed during prior work experience influences their identity work to become an entrepreneur; moreover, the resulting FSI shapes founders’ strategic decisions on market segment choice. This study highlights the significance of a distinct type of FSI, which we call ‘professional communitarian’, for professionals who engage in entrepreneurship beyond the boundary of PSFs.

  • When Top Managers’ Temporal Orientations Collide: Middle Managers and the Strategic Use of the Past

    Innan Sasaki, Masahiro Kotosaka, Alfredo De Massis

    Organization Studies (European Group for Organizational Studies)  45 ( 6 ) 825 - 853 2024.02

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  01708406

    　View Summary

    Use-of-the-past research has advanced our understanding of how top managers instrumentalize past knowledge, events and rhetorical constructions to advance their present-day interests. However, it is unclear how they use the past when they have divergent understandings of the past and different visions of the future. Temporal tensions can lead to a period of unsettlement in organizations, undermine the top management’s power base, and open up space for middle managers to take a central role in using the past. Through a longitudinal case study of a Japanese craft firm with a history of over 200 years, we examine how middle managers progressively take an active role in using the past through three processes: temporal mobility, temporal socialization and coalescing the past. Our findings challenge the somewhat linear conception of time in the use-of-the-past literature by elucidating the emergent, in-the-moment evolution of middle managers’ strategic use of the past. By adopting a process-analytic lens, our findings extend current understanding of the strategic use of the past as not undertaken by a few powerful individuals in a given moment, but a continually changing process enacted by multiple middle managers with different temporal orientations. Moreover, our findings contribute to the use-of-the-past literature by taking a relational perspective of temporality. Finally, we reconceptualize the strategic flexibility of middle managers from a temporality perspective, showing that they can alter the temporal orientations of those at the top and the bottom.

  • Environmental uncertainty and the entrepreneurial orientation–performance relationship among East Asian new technology-based firms: an institutional perspective

    Martin Hemmert, Adam R. Cross, Ying Cheng, Jae-Jin Kim, Masahiro Kotosaka, Franz Waldenberger & Leven J. Zheng

    Asian Business and Management (Asian Business and Management)  22 ( 4 ) 1683 - 1711 2023.04

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  14724782

    　View Summary

    Most extant research on the performance implications of entrepreneurial orientation (EO) has focused on established firms and on firm-specific and organizational factors. We contribute to EO research by studying the performance effects of EO sub-dimensions on the performance of new technology-based firms (NTBFs) and by examining environmental uncertainty, which is related to national institutional development, as an important boundary condition in an East Asian context. We analyze survey data from 2023 NTBFs in China, South Korea, and Japan and find that while the NTBFs’ performance is positively related to their entrepreneurial behavior, it is negatively related to their managerial attitude toward risk-taking. Furthermore, the positive performance effect of entrepreneurial behavior is weakened by environmental uncertainty, which is higher in China than in South Korea and Japan. Our findings suggest that for NTBFs, the performance implications of EO sub-dimensions need to be studied separately.

  • Human Capital of East Asian Start-up Founders and Entrepreneurial Orientation: A Three-Country Study

    Martin Hemmert, Ying Cheng, Adam Cross, Agata Kapturkiewicz, Jae-Jin Kim, Masahiro Kotosaka, Franz Waldenberger

    Academy of Management Annual Meeting 2024 (Chicago) ,

    　View Summary

    While the performance implications of firms’ entrepreneurial orientation (EO) have been extensively studied, less is known about EO antecedents. Furthermore, most studies that have examined EO predictors have focused on external or organizational factors. We identify start-up founders’ human capital, which has been found to influence business outcomes of start-ups, as an antecedent of the firms’ EO. We study the influence of four sub-dimensions of founders’ human capital (higher education, business leadership experience, entrepreneurial experience, and international experience) on three EO sub-dimensions (innovativeness, proactiveness, and risk-taking) in a longitudinal study of 1,029 start-ups from China, South Korea and Japan. While the founders’ higher education is not related to any EO sub-dimension, their entrepreneurial experience is positively related to the start-ups’ proactiveness, and their business leadership experience and international experience are positively related to all three EO sub-dimensions. From a theoretical perspective, our findings demonstrate a need to differentiate between sub-dimensions of founders’ human capital when studying their influence on start-ups’ EO. In addition to commonly used sub-dimensions, we highlight the importance of international experience. From a practical perspective, our results indicate that founders can leverage their business leadership experience, entrepreneurial experience and international experience to strengthen their firms’ EO.
