Robotics technology and firm-level employment adjustment in Japan

Unlike studies that analyze the impact of robotics technology on overall employment at the industry or firm level, this study investigated cross-division employment adjustment within a firm in an industry with greater diffusion and penetration of robotics technology. By examining changes in the composition of employment, we measured job creation and destruction at the division level and explored whether robotics technology, as a leading example of automation, not only displaces workers but also introduces new jobs in favor of labor. We made use of unique, division-level employment data for Japan’s manufacturing firms, together with industry-level data on the installation of industrial robots. We found that industry-level adoption of robots positively affects the firm-level job creation rate and the job destruction rate. Because the magnitude of the impact is larger for job destruction, robot adoption has an overall negative impact on firms’ net employment growth. Our findings suggest that the labor displacement effect of robotics technology and the emergence of new jobs due to technological change coexist even at the firm level.     

人口老龄化与劳动生产率的量化关系研究

在理论分析上,将劳动生产率和人口老龄化引入索洛经济增长模型,利用数理推导得出老龄化与劳动生产率存在非线性关系。实证层面上,基于2000-2017年省级面板数据,通过面板固定效应回归以及面板门槛回归分析了老龄化对劳动生产率的影响。研究结果表明:一、老龄化与劳动生产率存在"U"型曲线关系,二者现阶段处于"U"型曲线的左侧,即现阶段老龄化降低了劳动生产率;二、当企业转型升级或生产技术增长到一定阶段,老龄化与劳动生产率就呈同方向变化;三、虽处于"U"型曲线的左侧,但老龄化对劳动生产率的反向效应并不平滑,存在门槛效应。     

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.     

资源配置、全要素生产率与农业经济增长愿景

对2004~2010年我国不同地区农业的资源配置扭曲情况的分析表明:由于"二元经济"的影响,我国农业的资本和劳动存在着明显的跨部门配置扭曲。如能有效消除此类扭曲,我国农业TFP能提高6%~36%。各地区的资源再配置效应对农业TFP增长率有着显著影响,并且各地区的资源再配置效应存在明显差异。对全国各个地区而言,土地资源再配置效应都是影响农业资源再配置效应的主要因素,资本和劳动再配置效应则相对较弱。由此可见,促进城乡资本和劳动力市场一体化以及进一步完善农村土地流转市场是现阶段降低农业资源配置扭曲、促进农业TFP增长的主要途径。     

Medium and long-term impact of SARS on total factor productivity（TFP): Empirical evidence from Chinese industrial enterprises

This study examines the impact of the 2003 SARS epidemic on the total factor productivity (TFP) of Chinese industrial enterprises using a difference-in-differences (DID) approach. The results exhibit that SARS significantly reduces TFP by 3.12–5.81%, lasting for three to five years. Further, this impact is heterogeneous across industries. A significantly negative impact is found in labor intensive industries, while capital and technology intensive industries is less affected. Contrarily, a significantly positive impact is observed in those industries necessary for life and production. Mechanism tests show that the impact on TFP is caused by a reduction in labour productivity and a decrease in innovation investment after SARS outbreak. This study highlights the importance of more targeted policy on Covid-19 and similar epidemics both in industrial, national and international level.     

Does the productivity J-curve exist in Japan?-Empirical studies based on the multiple q theory

Brynjolfsson, Rock, and Syverson (2021) argued that the standard TFP growth is low during an investment boom for new technology such as the IT revolution. As the new capital is operated and productivity improves, the shape of the movements in the standard productivity growth resembles a J-curve. However, when costs associated with investment for new technology are recognized as intangible investment - which is not counted in the conventional value added –, the revised TFP growth including these unmeasured intangibles show different movements from the standard TFP growth. Following Brynjolfsson, Rock, and Syverson (2021), we examine the gap between the standard TFP growth and the revised TFP growth. According to their theory, unmeasured intangibles are estimated by the gap between the shadow value and the price of investment goods. We obtain this shadow value of investment through an estimated parameter in each asset using listed firm-level data and revise the standard TFP growth rate. In the case of all industries, the standard TFP growth is overestimated in most years in the late 1990s and the 2000s, because the growth in intangible investment associated with measured investment is lower than measured capital accumulation rate. When we focus on the IT-intensive industries, we find the productivity J-curve in the late 1990s, at the early stage of the IT revolution, as indicated by Brynjolfsson, Rock and Syverson (2021).     

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.     

Imperfect Competition, Economic Miracle, and Manufacturing Productivity Growth: Empirical Evidence from Taiwan

Several recent studies on total factor productivity (TFP) concluded that the East Asian economies benefited little from TFP growth. This study claims that the failure by previous studies to consider the effect of net indirect taxes and market imperfections resulted in the underestimation of the share of the contribution of labor input to factor income, which consequently led to the overestimation of capital share and understatement of TFP growth. Therefore, this study has modified the conventional approach of calculating factor shares by taking account of net indirect taxes and market imperfections and used the modified approach to estimate TFP growth in 16 Taiwanese manufacturing industries during the period 1979–1999. The conclusion drawn by the study is that TFP growth was the driving force behind the success of Taiwan's manufacturing industries, although many of these industries experienced a sharp decline in TFP during the 1990s.     

Females,the elderly,and also males: Demographic aging and macroeconomy in Japan

The speed and magnitude of ongoing demographic aging in Japan are unprecedented. A rapid decline in the labor force and a rising fiscal burden to finance social security expenditures could hamper growth over a prolonged period. We build a dynamic general equilibrium model populated by overlapping generations of males and females who differ in participation rate, employment type and labor productivity as well as life expectancy. We study how changes in the labor market over the coming decades will affect the transition path of the economy and fiscal situation of Japan. We find that a rise in the labor supply of females and the elderly of both genders in an extensive margin and in labor productivity can significantly mitigate effects of demographic aging on the macroeconomy and reduce fiscal pressures, despite their negative effects on equilibrium wages during the transition. The study suggests that a combination of policies that remove obstacles hindering labor supply and that enhance a more efficient allocation of male and female workers of all age groups will be critical to keeping government deficit under control and raising income across the nation.     

New,disaggregated, British railway total factor productivity growth estimates, 1875 to 19121

Total factor productivity (TFP) growth in Britain's railways in the last part of the nineteenth century and the first decade of the twentieth has been widely studied, not least because it can throw light on the question of the causes of overall slowdown in industrial growth. This article is concerned with the detailed mechanics of measuring TFP growth and with the use of results to compare growth across different companies. The article disaggregates TFP growth between different activities performed by railway companies (provision of locomotive power, operation of carriages and wagons, provision of permanent way, and working of traffic), and it also develops detailed measures of capital stock and capital costs using disaggregate data on assets employed in each activity. These improvements to existing methodology reduce, rather than increase, existing estimates of TFP growth. Consequently the results confirm the previously observed conclusion that productivity growth was slow. They show that while there were significant increases in goods train operating efficiency in the first decade of the twentieth century, the additional resources that were employed meant that these increases were slow to translate into overall TFP growth.     

Aging Workforce,Firm Productivity and Labor Costs in Korea: Are Older Workers Costly to Firms?

Are older workers costly to firms? This study aims to investigate the relationship between an aging workforce on firm productivity and labor costs using a unique Korean firm‐level panel dataset (WPS) covering the period from 2007 to 2011. The primary results show no evidence of a negative relationship between the proportion of older workers and firm productivity, and no significant relationship between the proportion of older workers and labor costs. In addition, the findings of this study implies that failure to account for unobserved firm heterogeneity and endogeneity of changes in age structure biases the results toward finding a correlation between the age structure of workers and firm productivity and labor costs. Consequently, there is a tendency to underestimate the true value of older workers for firms.     

Human capital and economic growth in Spain, 1850–2000

We investigate human capital accumulation in Spain using income- and education-based alternative approaches. We, then, assess human capital impact on labor productivity growth and discuss the implications of its alternative measures for TFP growth. Trends in human capital are similar with either measure but the skill-premium approach fits better Spanish historical experience. As education is a high income elastic good, human capital growth computed with the education-based approach seems upward biased for the recent past. Human capital provided a positive albeit small contribution to labor productivity growth facilitating technological innovation.     

服务业劳动者年龄结构对劳动生产率和工资的影响研究

将年龄结构引入到Cobb-Douglas 生产函数中,采用全国第六次人口普查和全国第七次人口普查的截面数据研究中国服务业劳动者年龄结构对劳动生产率和工资的影响,研究发现不同年龄区间劳动者比重对劳动生产率和工资的影响程度和影响方向存在差异。劳动者数量对劳动生产率影响为负向,16-24 岁、25-34 岁和45-54 岁劳动者比重对劳动生产率产生正向影响,而55-64 岁和65-74 岁对劳动生产率的影响分别由负转正和由正转负。劳动者数量及各年龄段劳动者比重对工资水平产生正向影响。因此,提出对不同行业劳动者教育水平进行合理要求、综合考虑不同年龄段劳动者能力以及给予老年劳动者合适的工作岗位等政策建议。     

Openness and total factor productivity in Swedish manufacturing, 1980–1995

Openness and Total Factor Productivity in Swedish Manufacturing, 1980–1995. — This paper studies the effect of openness on total factor productivity (TFP) growth. Using industry-level data for Swedish manufacturing from 1980 to 1995, the paper shows that integrated industries tend to be more engaged in R&D and have more entry and exit activity than other industries. The results show that domestic R&D intensity does not contribute to the TFP growth rate. Instead, openness to international markets, which helps facilitate technology spillovers, is an important factor. There is also some evidence that producers exiting the market are less productive, implying that such exits will increase the average productivity of the industry.     

Labor adjustment,productivity and output volatility: An evaluation of Japan’s Employment Adjustment Subsidy

This paper provides a quantitative examination of the impact of Japan’s Employment Adjustment Subsidy, a major employment insurance policy since 1975, on labor adjustment, productivity and output fluctuation in the iron and steel sector. A partial equilibrium industry model with heterogeneous establishments and aggregate uncertainty shows that the EAS reduces steady-state labor productivity by encouraging labor hoarding, and in some cases, preventing the exit of least efficient establishments. The EAS also reduces job flows and increases average establishment-level employment. Although the impact on productivity is roughly proportional to the size of subsidized workers in most cases, the effects of the subsidy on output and employment volatility are more than proportional. First, the subsidy can lead to a sizable increase in output fluctuations over business cycles by symmetrically increasing the output response to shocks. This result is achieved through lower output via a subsidy during unfavorable times and higher output via less time and money spent on hiring during favorable times. Second, the subsidy meets its primary objective of reduced employment volatility. The reduction can be considerable when firing costs are high.     

Process Versus Product Innovation: Do Consumption Data Contain Any Information?

In a model of endogenous growth in which product and process innovations are the joint outputs of an unspecified research program, we show that if quality growth is not captured by official price indices the usual isomorphism of product and process innovations breaks down. We derive and estimate a Euler equation for a representative consumer under the assumption of measurement error. Unobserved quality improvements account for at least half of growth, and real productivity growth in postwar United States was two to five times greater than measured total factor productivity (TFP) growth. We also find that at least 15% of the measured slowdown in TFP growth can be attributed to unobserved increases in the relative importance of product innovations.     

Public capital formation and labor productivity growth in Mexico

This paper addresses the important question whether public investment spending on economic infrastructure enhances economic growth and labor productivity in Mexico. Following the lead of the endogenous growth literature, it presents a modified production function which explicitly includes the positive or negative externality effects generated by additions to the public capital stock. Using cointegration analysis, the paper proceeds to estimate a dynamic labor productivity function for the 1955–94 period that incorporates the impact of the growth rate in the stocks of both private and public capital (as opposed to the flows) and the economically active population (EAP) (rather than the rate of population growth). The results suggest that (lagged) increases in public investment spending on economic infrastructure—as opposed to overall public investment spending—have a positive and highly significant effect on the rate of labor productivity growth. In addition, the estimates suggest that increases in government consumption expenditures may have a negative effect on the rate of labor productivity growth, thus suggesting that the composition of government spending may also play an important role in determining the rate of labor productivity growth. Finally, the findings call into question the politically expedient policy in many Latin American countries of disproportionately reducing public capital expenditures on economic and social infrastructure to meet targeted reductions in the fiscal deficit as a proportion of GDP.     

Can trade liberalisation in South Africa reduce poverty and inequality while boosting economic growth? Macro–micro reflections

South Africa is trapped in a cycle of modest growth, unacceptable poverty levels and record unemployment. This has led to renewed interest on the relationship between macro (growth) and micro (poverty and distribution) issues. This paper uses a macro–micro tool that couples a computable general equilibrium model with microsimulation models to examine the impact of further unilateral trade policy reforms on growth, poverty and welfare. Trade liberalisation alone has very minimal short-run macroeconomic consequences while its long-term impacts are positive and magnified by technical factor productivity (TFP) effects. Trade liberalisation has no appreciable impact on poverty in the short run even if we allow for trade-induced TFP increases. In the long run, however, poverty reduces even in the case when we do not allow for TFP increases. Trade liberalisation policy has been found to be progressive despite the low level of tariff protection remaining in South Africa.     

基于技能偏向性技术进步的经济增长动能分解

在传统Solow增长核算框架基础上引入异质性劳动投入以及技能偏向性技术进步,从而将经济增长分解为固定资本投入增长、劳动投入增长、技能结构深化、技能偏向性技术进步、中性技术进步及效率改进等五种动能。研究发现：第一,中国经济增长主要由固定资本投入以及全要素生产率增长共同驱动,其中资本投入对经济增长年均贡献率为61.64%,全要素生产率增长的年均贡献率则为35.66%,中国区别于其他中低收入国家的发展奇迹背后正是较快的全要素生产率增长;第二,即使对于高收入国家而言,资本投入仍然是主要的经济增长动能;第三,技能结构深化以及技能偏向性技术进步是全要素生产率的主要来源,二者对中国经济增长的年均贡献率分别为32.04%和21.27%;第四,资源配置效率变化是引起全要素生产率波动的主要因素,资源配置效率下降是导致2008年后中国以及大部分高收入国家全要素生产率增速放缓的主要原因。     

The Contribution of Associate's Degree Holders to U.S. Earnings,Labor Quality,Productivity, and Overall Economic Growth

There is substantial evidence on the importance of education as a driver of earnings, productivity, and economic growth. However, knowledge of the specific role of associate's degrees in U.S. economic growth is limited. We analyze the sources of U.S. economic growth and identify the contribution of associate's degree holders to improvements in earnings, labor quality, productivity, and overall economic growth. We find evidence that substitution toward workers with associate's degrees has increased U.S. earnings, aggregate labor quality, and productivity, and that these effects are concentrated in the health care, trade, and government sectors. While the average educational attainment of people entering the labor force has plateaued, our results suggest that shifting workers from some college to associate degrees could improve earnings, the quality of the workforce, productivity, and growth, potentially without more time spent in school.
