International Comparison of Japanese and Korean Banking Efficiency
Tomohiko Inui,Jungsoo Park,Hyun-Han Shin 서울대학교 경제연구소 2008 Seoul journal of economics Vol.21 No.1
This study investigates the pattern of changes in efficiency and productivity of the banking sectors at the firm level for the period of 1991-2005 using output distance function and applying the one-stage stochastic frontier approach. This study pools Japanese and Korean bank dataset to effectively compare the pattern of change between Japanese and Korean banking efficiency. Our results indicate that estimates of technical progress, technical efficiency, and total factor productivity (TFP) depend on the viewpoint about the true function of bank: intermediation approach, value-added approach, or operating approach. While intermediation approach results imply that the productivity has overall declined over the sample period for the both country banks, operating approach results are mixed for the two countries. Value-added approach indicates positive TFP growth for the both countries. In most cases, the levels of technical efficiency were further behind the technological frontier for the Korean banks than for the Japanese banks.

Import Competition, Industrial Agglomeration and Japanese Manufacturing Plants Performance
( Tomohiko Inui ),( Toshiyuki Matsuura ),( Kazuma Edamura ) 서강대학교 경제연구소 2010 시장경제연구 Vol.39 No.3
During the 1980s and 1990s, Japanese manufacturers began to relocate production from sites in Japan to low-wage East Asian countries such as China, Malaysia and Thailand. Imports of manufacturing goods increased substantially over the same period. This rapid rise in imports, and the quickening spread of globalization, has led to concerns among policymakers that employment growth and plant survival may suffer, with some regions more affected than others. This is the first paper which attempts to examine empirically effect of industrial agglomeration in the region on employment growth and plant survival to increased import penetration from low-wage countries. A rich, plant-level dataset on Japanese manufacturing sectors is used to examine this effect. We find that exposure to low-wage country imports has a negative effect on plant employment growth rates and its survival. However, where plants have high productivity, the effect of low-wage imports is ameliorated. We also find evidence that the advance of globalization has led Japanese firms to consider inter-industry agglomeration, such as output linkage to be less important. However, regions with more input linkages and intra-industry agglomeration remain firms` preferred location for the plants when exposure to low-wage countries is high.

A Decomposition of the Decline in Japanese Nominal Wages in the 1990s and 2000s
Naomi Kodama,Tomohiko Inui,Hyeog Ug Kwon 서울대학교 경제연구소 2015 Seoul journal of economics Vol.28 No.1
In the 1990s and the 2000s, the average nominal wage in Japan declined continuously. This is a sharp contrast to wage trends in other developed countries in the same period. This study seeks to provide new quantitative evidence on the possible factors contributing to the nominal wage decline in Japan’s so-called “two lost decades” employing the Blinder-Oaxaca decomposition method using data from the Basic Survey on Wage Structure for 1993-2008. We find that half of the decline of the average wage in the total economy is due to the growing employment share of low-wage industries. Further, we decompose changes in average wages at the industry level for three subperiods representing different phases of the business cycle in Japan. Controlling for worker characteristics, we find the wages of workers in the manufacturing, wholesale, and medical, health care, and welfare industries declined between 1998 and 2003. Further, our results show that 1997 was the turning point in terms of changes in the wage structure. In addition, we find that wages for workers with the same characteristics continued to decline in the 2000s, albeit at a slower pace, and the main factor responsible for the wage decline was changes in the composition of the workforce in the wholesale, retail, and medical, health care, and welfare industries.

An International Comparison of the TFP Levels of Japanese, South Korean, and Chinese Listed Firms
Kyoji Fukao,Tomohiko Inui,Shigesaburo Kabe,Deqiang Liu 서울대학교 경제연구소 2008 Seoul journal of economics Vol.21 No.1
To compare the TFP level of firms in Japan, China, and South Korea, we first estimated the TFP of firms in each country using the method of Good, Nadiri, and Sickles (1997). Then we estimated the relative TFP by industry in the benchmark year using Japanese industries as benchmarks and combined the estimated TFP of firms. When estimating relative TFP by industry for South Korea and China, we applied the industry-level price estimates of the three countries from the ICPA project and converted industry outputs and inputs into the same currency unit (Japanese Yen). The estimation results obtained indicate that the productivity of Japanese firms is still higher than that of their Chinese and South Korean counterparts but that the productivity of South Korean firms is rapidly increasing, with the emergence of some firms that are now overtaking their Japanese rivals in terms of productivity, particularly in the electric machinery sector.

What Determines R&D Intensity? Evidence from Japanese Manufacturing Firms
( Hyeog Ug Kwon ),( Tomohiko Inui ) 서강대학교 시장경제연구소(구 서강대학교 경제연구소) 2013 시장경제연구 Vol.42 No.1
We examine the determinants of research and development (R&D) intensity in Japanese manufacturing industries using a large sample of 13,000 firms for 1994. The results show that the technological opportunity and appropriability conditions of an industry play a central role in R&D investment. We also find that internal funds, firm size, advertising intensity, diversification, intra- and inter-firm networking technologies, licensing, export intensity, and foreign ownership positively affect R&D investment, while the effects of outsourcing, domestic ownership and market concentration are negative.
