‘Voice’ and ‘exit’ in Japanese firms during the Second World War: Sanpo revisited*

During the Second World War, the Japanese government and private sector searched for and implemented new mechanisms for coordination and motivation. One of these was sangyo hokokukai (sanpo). The Sanpo unit was basically an organization of the employer and employees of each firm, which held meetings to moderate labour relations. As a result of government policy to promote sanpo units, around 70 per cent of the total workers in Japan were organized into sanpo units in the early 1940s. As the members of trades unions and the workers of the companies that had factory committees were only 7 per cent and 5 per cent of the total workers in 1936 respectively, sanpo was the first large‐scale mechanism for Japanese employees to have a voice. This article examines the role of sanpo, using prefecture‐level and firm‐level data, based on a framework integrating the ‘voice view’ of unionism and transaction cost economics. It was found that sanpo reduced the participation rate in labour disputes, and enhanced labour productivity at least for some of the time.     

All entrepreneurial productivity increases are not created equal

We examine the impact of productivity increases in a setting where wealth‐constrained entrepreneurs are privately informed about whether their project will succeed with high (p_H) or low (p_L) probability. Not surprisingly, many productivity increases (e.g., an increase in p_H) generate gains for entrepreneurs and/or venture capitalists. However, some productivity increases (e.g., an increase in p_L) can generate widespread losses. Furthermore, entrepreneurs with low‐productivity projects can benefit more from policies that increase the productivity of high‐quality projects than from policies that increase their own productivity. Therefore, the design of policy to enhance welfare in the entrepreneurial sector can entail important subtleties.     

Male–female earnings differentials in early 20th century Manila

How might earnings of men and women have differed in poor countries a century ago? We know very little but a one-worker-in-ten labor market survey conducted in Manila in 1900 can help to establish baseline earnings patterns. In terms of raw means, women's earnings were about 30 percent less than men's, but both were distributed so that in some industries there were women who earned more than the average man. Controlling for hours, occupations and firm characteristics left female earnings discounts that varied by occupation from nothing to nearly half, ceteris paribus. Women workers concentrated in relatively skilled tobacco processing work, paid by the piece. Within this industry, productivity differentials were confounded by occupational segregation, however, in which men made the more expensive cigars and women the cheaper cigars and cigarettes.     

Population dynamics and economic growth in China

This paper focuses on two major elements of China's population dynamics—the rising proportion of workers in the population and the shift of rural workers from agriculture into industry and services—in a provincial-level analysis of per capita income and productivity growth during the last three decades. We measure the ‘mechanical’ contributions of these dynamics to per capita income as revealed by growth decompositions, before assessing the determinants of per capita income and productivity growth in a series of regressions that include the growth of the working-age to total population (WAP) ratio and a measure of sectoral employment change. Our results indicate that sectoral change has made a significant positive contribution to both per capita income growth and aggregate productivity growth, stemming from its positive impact on agricultural productivity growth—as predicted by the Lewisian dual economy model. However, the negative impact of sectoral change on productivity growth in the industrial and service sectors, combined with the negative impact of growth of the WAP ratio on both per capita income and aggregate productivity growth, suggests that the benefits of China's population dynamics during the last three decades have been overstated.     

The long march of history: Farm wages,population, and economic growth,England 1209–18691

The article forms three series for English farm workers from 1209–1869: nominal day wages, the implied marginal product of a day of farm labour, and the purchasing power of a day’s wage in terms of farm workers’ consumption. These series suggest that labour productivity in English agriculture was already high in the middle ages. Furthermore, they fit well with one method of estimating medieval population that suggests a peak English population c.1300 of nearly 6 million. Lastly, they imply that both agricultural technology and the general efficiency of the economy were static from 1250 till 1600. Economic changes were in these years entirely a product of demographic shifts. From 1600 to 1800, technological advance in agriculture provided an alternative source of dynamism in the English economy.     

Productivity-Wage Gaps Among Age Groups: Does the ICT Environment Matter?

This paper disentangles the age-productivity-wage nexus by estimating productivity and wage equations with longitudinal employer-employee panel data for Belgium. Results indicate that workers above 49 years are significantly less productive than their younger colleagues. Moreover, while relative productivities across age groups are not found to differ significantly between ICT and non ICT firms, the upward sloping age-wage profile appears to be somewhat steeper in ICT firms. Yet, whatever the ICT environment, findings show that young workers are paid below and older workers above their marginal productivity. This pattern is in line with the deferred payment model developed by Lazear (J Polit Econ 87:1261–1284, 1979).     

Productivity, efficiency, scale economies and technical change: A new decomposition analysis of TFP applied to the Japanese prefectures

This paper aims to examine the productivity change of the Japanese economy using the data pertaining to the 47 prefectures during the period 1981–2000. The decomposition analysis of the Hicks–Moorsteen–Bjurek productivity index is conducted to explore the sources of the productivity change. In summary, technical change and efficiency change are two of the most important components driving procyclical productivity. We find that relative their importance varies over periods. Supply shocks captured by technical change component caused upturns in productivity in the mid and late 1980s and in 1999 and 2000. Supply shocks also caused downturns in the early and mid 1990s. On the other hand, demand shocks captured by efficiency change component drove upturns of productivity in 1984, 1990 and 1996, when supply shocks were not detected. J. Japanese Int.

Aging,automation, and productivity in Korea

This paper examines the impact of aging in the Republic of Korea on productivity as measured by labor productivity or total factor productivity (TFP). It also assesses the effect of robot adoption on the relation between aging and productivity using industrial level data. We find that aging is negatively associated with labor productivity and TFP growth. This is true particularly when aging is measured by increases in shares of old workers. If aging is measured by increases in the median age of workers, the negative effect is weaker. Evidence also suggests that robot technology mitigates aging's negative effect on productivity growth, particularly when productivity is measured by TFP. However, there is no evidence that robots are more heavily adopted in aged industries. While robot technology does not directly contribute to higher productivity growth, our findings suggest that the robot adoption can alleviate the negative impact of aging by helping workers in their 50s and 60s contribute less adversly to productivity growth.     

Flexibility versus Commitment in Personnel Management

This paper compares human resources (HR) policies embedded in the Japanese and U.S. management systems. We adapt a model from the literature on irreversible investment and use it to examine the trade-off between flexibility to adjust the labor force and higher productivity stemming from the greater commitment of the firm to its employees. In the model, two types of contracts with otherwise identical workers can coexist. One possibility is for firms to commit to a permanent employment contract that precludes dismissal at will. The alternative is a temporary employment contract that allows flexibility to adjust the firm's labor force during demand downturns, but involves higher labor cost per unit of output. Using an example, we illustrate the possible magnitude of the value of flexibility and suggest that adopting long-term contracts in the wrong environment can significantly reduce firm value. The model yields predictions for the optimal labor force composition and its relation to the characteristics of the firm's market. We also consider practices that develop to complement permanent employment. The predictions are then examined in light of evidence on the HR practices in Japan and the United States in the past 50 years and are found to be consistent with the stylized facts in the literature.

Some Evidence on the Relationship between Performance-Related Pay and the Shape of the Experience-Earnings Profile

We investigate the relationship between performance-related pay (PRP) and the shape of workers' experience-earnings profiles. In particular, we argue that the slope of the profile depends critically upon the degree of ‘equity’ held by workers in their enterprise as measured by the extent of PRP. The implication is that the slope of the profile for PRP workers falls between those of their zero-equity fixed-wage, and one hundred per cent equity self-employed, counterparts. Our empirical analysis of three British data sets, namely the British Social Attitudes Survey, the British Household Panel Survey, and the British Family Expenditure Survey, supports this prior.     

The industry origins of Japanese economic growth

This paper presents new data on the sources of growth for the Japanese economy over the period 1960–2000. The principal innovation is the incorporation of detailed information for individual industries, including those involved in the production of computers, communications equipment, and electronic components as information technology equipment. We show that economic growth is dominated by investments and productivity growth in information technology, both for individual industries and the economy as a whole. We also show that the revival of total factor productivity growth accounts for the modest resurgence of the Japanese economy since 1995. J. Japanese Int. Economies 19 (4) (2005) 482–542.     

Productivity loss and reinstatement as a legal remedy for unjust dismissal

There are two types of legal remedies for unjust dismissal, damages or reinstatement. Although workers' motivation is negatively influenced by employment adjustments such as a wage cut or layoffs, fired workers can receive a remedy when they are protected by dismissal regulations. We consider which legal remedy policy is better, damages or reinstatement, from the viewpoint of workers' motivation at workplaces. Under a reinstatement policy, firms are more likely to make an employment adjustment, and reinstatement is dominated by damages from the viewpoint of social welfare when the productivity loss caused by employment adjustment is minor. On the other hand, when the productivity loss is serious, employment adjustment is more likely made under the damages policy, and reinstatement can be desirable. J. Japanese Int.

Can older workers stay productive? The role of ICT skills and training

This paper quantitatively examines the effects of aging on labor productivity using individual worker data in Korea. We find that information and communications technology (ICT) skills and participation in job-related training can help older workers stay productive. The estimation results present that ICT skills, a measure incorporating an individual’s proficiency in ICT skills and their utilization in the workplace, has a positive effect on the wages of the older workers aged 50–64 with a high level of education or in a skill-intensive occupation. Job training also has a significant positive effect on the wages of older workers. These results imply that compared to younger workers, well-educated older workers can obtain greater productivity increase through ICT skill attainment and their adequate use, and job-training. The evidence suggests that a productivity decrease in line with the aging process can be mitigated by training aging workers to equip themselves with ICT skills.     

Interindustry effects of productivity growth in Japan: 1960–2000

Combining conventional sectoral growth accounting and the static open input–output price model, we analyze the sources of growth of product prices in Japan during the period 1960–2000. Using the input–output framework, we take into account not only the effects of factor costs and productivity within a sector, but also their impacts outside of the sector. We find that Japan's deflation in the 1990s was characterized by low growth of wage rates, low productivity growth, and a low rate of return on capital. Until 1990, productivity improvements compensated for factor cost pressures on output price, especially the rapid growth of labor cost. In contrast, during the 1990s, decreasing rates of return on capital, not productivity improvements, canceled out the inflationary effect of wage growth. J. Japanese Int.

Technological Progress and Youth Employment in South Korea

ABSTRACT

This paper analyzes the extent to which technology progress and youth employment are related. In doing so, we divide workers into two groups – young workers and old (prime-aged) workers - and then estimate the elasticity of substitution between (physical) capital and workers à la Jaimovich et al. (2013. “The Demand for Youth: Explaining Age Differences in the Volatility of Hours.” American Economic Review 103 (7): 3022–3044) by using the Korean labour market data between 2000 and 2014. Our findings indicate that the elasticity of substitution is greater (or at least not smaller) for young workers than for old workers.     

Fluctuations in Unemployment and Industry Labor Markets

Throughout the 1990s, and particularly in the mid- to late-1990s, the Japanese employment situation went from bad to worse. We investigate the causes of rising unemployment in Japan, using data on individual workers from the “Special Survey of the Labor Force” between 1988 and 1999. This research focuses on the effect of labor market segmentation by industry on labor flows. Our findings reveal that unemployment in the construction industry and, more recently, in the service industry has contributed greatly to the national unemployment rate. We also find that most successful job transfers occur within the same industry, even though workers may experience some periods of unemployment. Finally, our results show that labor market conditions in each industry affect the probability that a worker will fall into unemployment as well as the probability that an unemployed worker will find new employment. These findings suggest that the Japanese labor market is segmented by industry and this segmentation contributed to the worsening unemployment in Japan. J. Japan. Int.

Golden Rules of Wages

We consider a neoclassical growth model where labor collectively chooses labor share to maximize its steady‐state wage rate. In the basic two‐factor model, labor maximizes the steady‐state wage rate by setting labor share equal to the elasticity of output with respect to labor. This is precisely the competitive outcome. Only when we consider the model with organized and unorganized labor types can organized labor raise its steady‐state wage by choosing a higher than competitive labor share. Organized labor can benefit by choosing a higher labor share only at the expense of unorganized workers; not capital. We also analyze a version of the model that incorporates a tradeoff between collective bargaining opportunities and skill acquisition. All else equal, a higher skill premium leads organized labor to choose a higher labor share. Organized labor benefits again at the expense of skilled workers; not capital.     

Competition and productivity in Japanese manufacturing industries

This paper examines the determinants of productivity in Japanese manufacturing industries, looking particularly at the impact of product market competition on productivity. Using a newly available panel data on around ten thousand firms in Japanese manufacturing for the years 1994–2000, I show that competition, as measured by lower level of industrial price–cost margin, enhances productivity growth, controlling for a broad range of industrial and firm-specific characteristics. Moreover, I suggest that market power, as measured by either individual firm's price–cost margin or market share, has negative impact on productivity level of R & D performing firms. J. Japanese Int.

Aging labor,ICT capital,and productivity in Japan and Korea

This study examines how aging affects labor productivity using industry-level data of Japan and Korea. The analysis shows that, for both Japan and Korea, aging has positive effects on labor productivity when older workers are working in industries with a large share of information and communication technology (ICT) in the capital stock. We also find that, on average, older workers exert positive effects on labor productivity across all industries when they are low-educated in Japan and high-educated in Korea. In addition, a complementary effect between ICT capital and older workers is observed for both high- and low-educated workers in Japan but only for low-educated workers in Korea. The complementarity between ICT and old workers existed in both manufacturing and services industries of Korea and Japan.     

Estimating the Impact of Transgenic Bt Cotton on West and Central Africa: A General Equilibrium Approach

West and Central Africa (WCA)’s cotton sector is experiencing rising production costs and lower yields, reversing decades of growth. Declining input use, soil fertility and inefficient chemical pest controls are contributing factors. We evaluate the potential impact of Bt cotton on WCA using a multiregion general equilibrium model and multicountry estimates of Bt-induced productivity. We find that Bt cotton raises growers’ returns, land value and welfare. Released labor from cotton is shifted to food crops hence reducing labor shortage constraints. Overall, results indicate that potential gross benefits from Bt cotton are substantial for WCA cotton sector, and that the economic costs of nonadoption are equally significant.
