Daiji Kawaguchi of University of Tokyo reviews “Building a New Economy: Japan's Digital and Green Transformation” by D. Hugh Whittaker. The Econlit abstract of this book begins: “Explores institutional and ideational change in Japan and whether or not these are coming together to form a new growth model, focusing on the changing nature of the Japanese state and state–market relations, corporate governance, management and employment, education and training, and innovation and entrepreneurship.”

Firms frequently provide general skill training for workers. Theories propose that labor market frictions entail wage compression, generate larger productivity gains than wage growth to skill acquisition, and motivate a firm to offer general skill training, but few studies directly test them. We use unusually rich data from a temporary help service firm that records both workers’ wages and their productivity as measured by the fees charged to client firms. We find that skill acquired through training and learning by doing increases productivity more than wages, with such wage compression accounting for half of the average 40% productivity growth over 5 years of tenure.

This paper studies the relationship between industrial robots and employment in Japan on the basis of a unique dataset that allows us to calculate the unit price of robots. Our model combines standard factor demand theory with a recent task-based approach to derive a simple estimation equation between robot prices and employment, and our identification strategy leverages heterogeneous applications of robots across industries and heterogeneous price changes across applications. We find that the decline in robot prices increased both the number of robots and employment by raising the productivity and production scale of robot-adopting industries.

We design and conduct a firm-level survey on the use of COVID-19-related government programs, in collaboration with Tokyo Shoko Research, LTD (TSR). Combining the survey results with the financial statements of the respondent firms, we investigate the factors behind the allocation of various government programs. We find that firms that had low credit scores in 2019, before the COVID-19 pandemic, were more likely to apply for and receive the subsidies and concessional loans offered by the Japanese government in 2020, controlling for the sales growth after the onset of the pandemic. Firms with low credit scores are not necessarily zombies, which are defined to be the firms that are non-viable but kept alive by assistance from creditors and/or the government. Our result suggests that the government assistance may have subsidized some poorly performing firms that were not yet zombies before the pandemic.

How would people spend additional time if confronted by permanent declines in market work? We examine the impacts of cuts in legislated standard hours which raised employers' overtime costs in Japan around 1990 and in Korea in the early 2000s. Using time-diaries from before and after, we show the shocks were effective -- per-capita hours of market work declined discretely. The economy-wide drops in market work were reallocated solely to leisure and personal maintenance. In the absence of changing household technology a permanent time gift leads to no increase in time spent in household production by the average individual.
