R&D subsidies and business R&D: Evidence from high-tech manufacturing firms in Jiangsu

We investigate how R&D subsidies affect business R&D investments using cross-section data of high-tech manufacturing firms in Jiangsu province of China. Our estimations based on propensity score matching suggest that public subsidies positively influence business R&D investments. Further classifying firms into different groups by size, financial constraints, and ownership, we find that the stimulation effect is more significant and stronger for smaller firms, more financially constrained firms, and private-owned firms. The heterogeneity of policy effects with respect to export status, Relative Comparative Advantage index, region, and industry are also discussed.     

TFP growth slowdown and the Japanese labor market in the 1990s

Unemployment in Japan nearly tripled during the 1990s. Underlying this upsurge lie an increase in the probability of workers to lose their jobs and a decrease in the probability that the unemployed find jobs. This paper analyzes the sources responsible for these labor market changes in Japan in the decade of the 1990s. We build, calibrate, and simulate a neo-classical growth model with search frictions in the labor market. Using actual TFP data, the model is able to reproduce the path of unemployment and the job flows, as well as that of output. We find it to be the decrease in productivity, coupled with the reduction in hours worked, which curtails the profits of firms, inducing a drop in employment and an increase in unemployment.     

Debt,R&D investment and technological progress: A panel study of Japanese manufacturing firms' behavior during the 1990s

Based on a panel data set of Japanese manufacturing firms in research-intensive industries, we investigate quantitatively the extent to which outstanding debt affected firms' R&D activities during the 1990s. We find that massive amounts of outstanding debt had a significant, negative effect on R&D investment during that time. We also find that R&D expenditures were closely linked to firm-level total factor productivity growth over the same period. In fact, a ten-percentage-point increase in the debt–asset ratio lowered the rate of firm-level total factor productivity growth by 0.26 percentage points between 1999 and 2001, because it reduced R&D activities.

R&D intensity and domestic and cross-border M&A of Japanese firms before domestic M&A deregulation

In this paper, we examine the determinants of mergers and acquisitions (M&A) in Japan prior to the deregulation of domestic M&A transactions. We reveal that firm growth strategies and institutional differences in domestic and cross-border transactions are key determinants of the differences in M&A behavior. Our estimates show that domestic M&A activities are negatively related to research and development (R&D), suggesting that low technology-intensive firms have a tendency to engage in domestic M&A. For cross-border M&A, firm R&D activities have a significant positive effect, implying that a firm's own technology is important for absorbing foreign technology or competing in the host country.     

R&D,unemployment, and labor market policies

This paper studies the effects of labor market policies on R&D activities and unemployment. I develop a search and matching model in which firms’ R&D decisions are endogenously determined. The model demonstrates that more intensive labor market policies that protect workers reduce the levels of R&D activities. This study offers a theoretical framework to understand the relationship between R&D activities, labor market policies, and unemployment which is discussed in empirical studies.     

R&D and patenting activities of foreign firms in China: The case of Japan

This study investigates the research and development (R&D) and patenting activities of foreign firms in China. Utilizing a panel dataset of Japanese affiliates during the period 2001–2007, we first examine the determinants of R&D activity and find that local market-oriented firms place more emphasis on R&D, whereas process export-oriented firms are less likely to conduct R&D. Affiliates within a large business group that has more affiliates have a higher propensity to undertake R&D. Using only firms with positive R&D expenditures, we next estimate the patent production function. Results indicate that the patent elasticity of R&D for Japanese affiliates is high, suggesting that they are more productive on patent production than other firms. Moreover, local market-oriented firms do need more patents to protect their products, whereas scientific firms demonstrate a lower willingness to register patents in China.     

R&D Spillovers for Public R&D Productivity

ABSTRACT

This paper empirically investigates whether the productivity of a public (government-funded) R&D project improves when the aggregate R&D investment in the same technology field increases. Based on the unique project level data that cover almost entire public R&D projects in Korea, this paper shows that aggregate investment in other public R&D projects in the same technology field increases a public R&D project’s outputs both independent of its project expenditure (additive spillover effects) and interactive with its project expenditure (multiplicative spillover effects). The spillover effects from the aggregate private R&D investment in the same technology field also exist, but to a much lesser extent.     

Japanese labour in the 1990s: stability and stagnation

We review the state of the labour market and employment practicesin Japan over the past 15 years and try to evaluate the natureof the changes that have been occurring. We also look at howgovernment policy has reacted to the conditions in the labourmarket and what implications this has for the future. Althoughthere has been a continual shift of resources away from manufacturingand agriculture into services, employment practices have notbeen changing so rapidly, and job protection is actually stronger.This, along with wage restraint, accounts for why unemploymenthas only increased by some 2.5 percentage points during almosta decade of stagnation. We also note that much government policyhas acted to maintain existing employment practices and thatlabour economists are divided as to whether or not this is agood thing.     

Self-selection and performance of R&D input of heterogeneous firms: Evidence from China's manufacturing industries

Applying the theories of heterogeneous firms and the propensity score matching difference-in-differences (PSM-DID) method to a rich dataset of Chinese manufacturing firms, this paper examines the self-selection of firm-level R&D input and estimates the net effect of R&D on productivity. The analysis shows that (1) for Chinese manufacturing firms as a whole, R&D input is influenced by firm productivity: more productive firms are more likely to invest in R&D; (2) controlling for the self-selection effect, the net output elasticities of R&D input in one year and two years after R&D input are 3.92% and 5.25%, respectively; (3) although state-owned enterprises (SOEs) are more likely than all other ownership groups to invest in R&D, the R&D input is not productive; (4) although enterprises owned by investors outside of Mainland China are the least likely to invest in R&D, the output elasticity of R&D is more significant and larger in this group than in SOEs and privately owned Chinese firms; and (5) surprisingly, the net effect of R&D is not significant in high-tech industries. Policy implications are derived from the findings.     

Modeling coordinated foreign exchange market interventions: The case of the Japanese and U.S. interventions in the 1990s

During the past thirty years, central banks often intervened in foreign exchange markets. Sometimes they carried out foreign exchange market interventions on a unilateral basis. However, central banks often coordinated their foreign exchange market interventions. We develop a quantitative reaction function model that renders it possible to study the factors that made central banks switch from unilateral to coordinated interventions. We apply our model to the intervention policies of the Japanese monetary authorities and the U.S. Federal Reserve in the yen/U.S. dollar market during the period 1991–2001. To this end, we use recently released official data on the foreign exchange market interventions of the Japanese monetary authorities. JEL no. F31, F33, G14, G15     

A Duality Between Cost-Reducing R&D versus Quality-Improving R&D and Welfare Analysis in a Hotelling Model

Two versions of research and development (R&D) activities in a Hotelling model with endogenous spillover effect, one with cost-reducing R&D and the other with quality-improving R&D, are analyzed in this paper. The result points out that two such kinds of R&D activities will share identical strategic properties, and that we shall be able to derive the equilibrium strategies of a quality-improving R&D model from those of a cost-reducing R&D model, and vice versa. It is found that the special market demand in a Hotelling model in fact plays a crucial role as well. This paper also provides a welfare analysis, the results of which show that government intervention via taxing the locations and subsidizing R&D efforts can remedy the market failure resulting from excess differentiation on locations and under-investment on R&D expenditures in non-cooperative equilibrium.     

Substitution in R&D across countries

Suppose imitation becomes easier in developing countries due to international technology diffusion or other reasons. If imitation also occurs in the North, Northern imitators (as well as innovators) would become less secure from low-cost Southern imitations. Does the resulting rise in Southern imitation lead to a decrease in Northern imitation (and perhaps even innovation)? If so, does the overall rate of imitation rise or fall? This paper builds a product cycle model with imitation in both the North and the South (along with innovation in the North) to address questions related to the level and composition of imitation across countries.     

Exports as an indicator on or promoter of successful swedish manufacturing firms in the 1990s

We study the link between exports and productivity at the firm level. Like in previous studies we get support for the hypothesis that more productive firms self-select into the export market. In addition, and contrary to many of the former studies, we also obtain evidence that exporting further increases firm productivity. Exporting firms appear to have significantly higher productivity than nonexporting. Moreover, exporters—mainly firms that increase their export intensities—have higher output growth than nonexporters. Reallocation of resources between firms may then have contributed to overall manufacturing productivity growth. Hence, we try to quantify the importance of reallocation. JEL no. F10, D24

R&D Subsidies and Foreign Direct Investment

We devise a model in which domestic firms do applied R&D, which can be subsidized by the government, and foreign firms with superior technology can enter in the domestic market. Foreign Direct Investment can act as a substitute of subsidies to improve domestic R&D, the share of domestic leading firms and consumption. Relatively closed economies may benefit from R&D subsidization while relatively open economies may not. For relatively low growth of the technological frontier, it is optimal to subsidize R&D and close the economy to foreign investment but the opposite happens for relatively high growth. Numerical simulations show the economy dynamics after policy experiments.     

Small business service firms and the 1990s recession in the United Kingdom: Implications for local economic development

During the 1990s recession, the UK experienced a dramatic growth in employment in information-intensive business firms. This paper explores this growth with reference to small management consultancy and market research firms. Business service firms continued to be established and to grow during the recession because of three related attributes: professional expertise, an existing reputation and a network of client contacts. These attributes are related to the theoretical work of Granovetter (1973; 1982; 1985) who argues that “weak ties” operate to connect different groups of people together. The implications of these attributes for local economic development are considered. Success for all companies at the level of the local economy will be partially dependent on efficient and effective use of available business service expertise. The three attributes make it impossible to develop successful mechanisms to encourage the formation of business service companies in areas with underdeveloped service infrastructure. Mechanisms, however, may be developed at the local level to encourage the establishment of “weak ties” between local companies and regional and national providers of business service expertise.     

R&D,financing constraints and export green-sophistication in China

This paper provides a theoretical and empirical analysis of the effects of R&D and financing constraints on the green-sophistication of Chinese firm exports. The theoretical model predicts that firms' R&D expenditure improves the level of green sophistication and financing constraints have moderating effects on firms' the export green-sophistication. The paper constructs an index of the export green-sophistication by incorporating green coefficient in traditional export sophistication. We use the data from the China industrial firm database and confirm our theoretical predictions. The financing constraints are found to have a significant moderating effects on the relationship between R&D and export green-sophistication in basic test and robustness check.

DID Japanese main banks improve the technical efficiencies of their non-financial client firms in the 1980s?

This paper tests the hypothesis that the Japanese main bank system was not effective in enhancing technical efficiency in the non-financial corporate sector in the 1980s. Technical efficiency is defined as the ratio of a firm's actual to its potential output for given input levels and technology. During the eighties, it did not improve consistently and significantly in Japanese manufacturing firms which have close ties to a main bank.
