  • Mechanisms to improve labor productivity by performing telework

    Sachiko Kazekami

    Telecommunications Policy (Elsevier)  掲載決定済 2019

    Research paper (scientific journal), Single Work, Accepted,  ISSN  0308-5961

     View Summary

    This study investigates mechanisms underlying the influence of telework on labor productivity in Japan. First, this study finds that appropriate telework hours increase labor productivity, but when telework hours are too long, telework decreases labor productivity. Second, telework increases life satisfaction, and life satisfaction improves labor productivity. However, telework increases the stress of balancing work and domestic chores, contrary to Japanese governmental expectations, and the stress decreases life satisfaction. The stress, fortunately, does not directly reduce labor productivity. Although telework increases happiness and work satisfaction, these factors do not influence labor productivity. Third, this study clarifies that telework is more efficient for improving labor productivity if workers commute more than 1 hour or commute by trains or buses that are usually very crowded during rush hours in Japan. Finally, the effect of telework for workers who have a greater number of potential trivial duties is insignificantly larger. Supervisors and colleagues often ask others to perform trivial, extra tasks without regard for schedules. Telework may help workers avoid such trivial duties and increase labor productivity. However, the importance of trivial duties is also demonstrated in this study.

  • Local Multipliers, Mobility and Agglomeration Economies

    KAZEKAMI Sachiko

    Industrial Relations 56 ( 3 ) 489 - 513 2017.07

    Research paper (scientific journal), Single Work, Accepted

     View Summary

    This paper demonstrates that when one new job is generated by attracting a new
    business in the tradable sector in a local economy, a significant number of additional
    jobs are created in the nontradable sector when labor mobility is high.
    However, these multipliers disappear when labor mobility is low. This paper confirms
    that regions with higher labor inflow have larger multipliers. Furthermore,
    the spillover effect of agglomeration economies in the tradable sector is significantly
    positive on the nontradable sector.

  • Do service sectors need core sectors to improve their productivity?

    KAZEKAMI Sachiko

    Eurasian Economic Review 7 ( 3 ) 389 - 410 2017.05

    Research paper (scientific journal), Single Work, Accepted

     View Summary

    Examining Japanese micro-data, this study demonstrates that large core
    sectors (specialized or manufacturing sectors) in a local economy improve the
    productivity in the local non-tradable service sectors, and thereby increase
    employment. The size of service sector demand is determined by the size of the
    local economy, which, in turn, is determined by these large core sectors. The core
    sectors are generally sectors with tradable goods and services and their demand is
    not limited by the local market size as their goods and services supply multiple
    regions. A large demand for the service sectors induces heightened competition and
    improves their productivity through Darwinian selection or efficiency improvements
    within firms. Moreover, the spillover effect from core sectors might affect local
    service sectors. As a result, a 1% increase in added value in the specialized sectors
    in the previous estimation period, as well as a 1% increase in the change in added
    value in the specialized sectors, and a 1% increase in added value in the manufacturing
    sectors in the previous estimation period affect an increase in the productivity
    of the service sectors by approximately 4–5, 4 and 2.5%, respectively.
    Moreover, an increase of 100 thousand dollars of added value in the specialized
    sectors increases employment by 26 employees in the local service sectors. Furthermore,
    this study confirms efficiency improvements within firms as a productivity
    mechanism.

  • Evaluating place-based job creation programs in Japan

    KAZEKAMI Sachiko

    IZA Journal of Labor Policy    1 - 27 2017.01

    Research paper (scientific journal), Single Work, Accepted

     View Summary

    First, this paper empirically evaluates the incidence of the Japanese place-based job
    creation program, which has rarely been studied in Japan. The program increases
    employment, especially in the agricultural, retail trade, and service sectors, which
    most treated municipalities promote. Second, this paper explores the municipalities
    that the program affects most. Those with large aging populations and those with
    small working age populations decrease the effects of the program. Third, this paper
    assesses the externality effect of this program and does not observe a strong
    reduction in sales, workers, or establishments in the neighboring municipalities of a
    treated municipality.
