　View Summary

First, using the sequential linear panel data-estimation model and maps, we demonstrate the relocation of job-posting places, especially for part-time jobs. We use data on the number of job postings at the public employment security office in Japan. These changes in the posting places are clearly observable in the retail trade for part- and full-time jobs. In contrast, we do not find discernible relocation in the information-services industry. The impact of the COVID-19 shock varies by geographic location. However, if people’s mobility rate, the number of infected people, or the declaration of the state of emergency are controlled for, the number of job postings differs among areas.
Therefore, second, this study explores the factors that account for the differences in the number of job offers among areas. We find that industrial diversity increases the number of job postings for part- and full-time jobs in 2021, that is, one year after the first wave of the pandemic began. In contrast, industrial specialization has a negative impact in 2021. Higher rigidity of finance decreases the number of part-time job postings immediately after the first wave of the pandemic because local governments cannot provide various support measures to create jobs. However, this financial effect disappears with time. Furthermore, higher financial capability positively affects part-time job postings, although they are not efficient in creating full-time jobs. The unemployment rate in 2015 negatively affects the regional differences in job postings after 2021. Regarding whether firms seek regions with rich human resources, the result is unexpectedly unclear.

Mechanisms to improve labor productivity by performing telework

　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.

　View Summary

This study demonstrates the regional differences in the epidemic shock on the local labor market and evaluates the spread from the non-tradable sectors damaged by the COVID-19 pandemic to the other sectors. We use the number of job posting data in Japan to demonstrate this difference.
This study controls mobility, the monthly average of infected people, and the industrial structure in the pre-pandemic era that determines the local consumption and labor demand. Under such controlled conditions, the diversity of industrial structure measured by the number of establishments positively impacted the number of job postings from April to December in 2020 after the first wave of the COVID-19 pandemic. By contrast, the financial rigidity of the local government negatively impacts the number of job postings. This study examines whether firms consider the human capital resources of the local labor market. However, unlike our expectations, the rate of admissions into universities from high school decreases the number of job postings. The unemployment rate does not affect the job offers.
This study examines the Tokyo and Osaka commuting zones between April and December 2020, to investigate where jobs are offered. We find that the surrounding areas of the central cities in the commuting zones recover the number of job posting faster than the central cities. The dramatic increase in the prefectures outside of Tokyo and Osaka commuting zones was not observed from April to December 2020. The pandemic has affected the non-tradable sectors, while the economic crisis affected the tradable sectors such as manufacturing. This study demonstrates that the spread effect from the shock in the non-tradable sectors maybe smaller than that in the tradable sectors.
