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.
