North–South models of intellectual property rights: an empirical critique

Do Southern intellectual property rights (IPRs) affect Northern innovation? There is much theoretical debate on the impact of IPRs in the South on the incentives of Northern firms to innovate and transfer technologies to the South. While empirical research exists on the effects of Southern IPRs on Northern technology transfers, empirical evidence on the effects of Southern IPRs on Northern innovation is absent. This paper seeks to fill that gap. Using a comprehensive micro-database of US multinational firms and their foreign affiliates in developed countries, this study finds that patent protection in the South has statistically insignificant effects on the research and development of these firms. Rather, the patent regimes of developed countries matter significantly to the R&;D of these firms. Developing countries constitute a relatively small share of the world market so that variations in the patent rights of developing economies have contributed marginally to Northern incentives for R&;D.     

The value of intellectual property rights to firms and society

Economists view intellectual property rights (IPRs) as policytools for encouraging innovation, but they recognize that theycan also inhibit competition. There are many types of IPRs andinstitutions concerned with their administration. We begin byoutlining how these complex and varied rights are supposed towork and how they interact with other characteristics of firmsand markets. We then survey the available literature on patents,trade marks, and copyright to assess the value of these IPRsto firms and the costs to firms of acquiring and defending theirrights. The paper concludes with suggestions for topics requiringfurther research to inform public policy better.     

Strategic R&D Location in European Manufacturing Industries

We empirically test a model of foreign research and development (R&D) investments that takes into account strategic interaction in R&D location decisions by multinational firms in the context of R&D cross-investments, R&D spillovers and foreign technology sourcing strategies. We find support for most of the predictions of the model in an empirical analysis of the location of patented innovations by the largest European manufacturing firms in 22 ISIC industries during 1996–1997. For technology leaders in Europe, foreign R&D ratios respond positively to host country product market competition, while technology laggards avoid these locations. Foreign R&D by technology laggards increases more strongly with the efficiency of (reverse) international technology transfer while leaders are attracted more strongly to countries with better intellectual property rights (IPRs) protection. Foreign R&D of both technology leaders and technology laggards increases with the size of the local knowledge pool and the size of manufacturing operations in the host country.

The international regulation of intellectual property

The International Regulation of Intellectual Property. — The WTO Agreement on Trade-Related Intellectual Property Rights (TRIPS) will usher in a markedly stronger global system of defining and protecting intellectual property rights (IPRs). This paper first discusses the concept of intellectual property and the need for its protection and regulation. It presents evidence on the wide variations in IPRs across countries and discusses how TRIPS will affect these differences. Theoretical predictions about how this stronger system will influence global trade, investment, and technology innovation and diffusion are ambiguous, but limited empirical evidence suggests a modest positive effect overall. However, the distribution of costs and benefits will vary.     

The impact of foreign direct investment in China on employment adjustments in Taiwan: Evidence from matched employer–employee data

Using a unique matched employer–employee dataset on Taiwanese manufacturing, we examine the impact of foreign direct investment in China on domestic employment adjustments controlling for firm and worker heterogeneity as well as for potential endogeneity of firms’ expansion in China. Our findings suggest that workers employed at firms with higher levels of investment in China are more likely to leave the firm, compared with workers at firms with zero or lower levels of investment in China. We provide evidence that foreign expansion in China decreases worker employment security at parent companies, particularly for low-skilled workers. Employment adjustments through employer-to-employer transitions are found to be highly associated with wage losses, with the strongest wage effects for low-skilled workers who shift employment between industries. Moreover, we find no evidence that FDI in China contributes to skill upgrading at parent companies.     

Foreign Direct Investment Inflows and Intellectual Property Rights: Empirical Evidence from Different Income Groups

This study examines the impact of intellectual property rights (IPRs) on Foreign direct investment (FDI) inflows by considering global data with three income groups classified by World Bank (i.e. high-, middle-, and low-income groups). The empirical model relates FDI inflows to IPRs, controlled by a set of known variables, namely GDP per capital, trade openness, real exchange rate, and real interest rate. The study covers panel data of between 35 and 100 countries for the period 1980–2014. The panel cointegration tests suggest that FDI inflow and IPRs with the other control variables are cointegrated for full countries and high-income group. Their estimated (long-run) coefficients are 0.04 and 0.18, respectively, but insignificant in the short-run. The impact (short-run) of TRIPS agreement is positive for full countries, but negative for low-income group. Non-causality tests further support the role of IPRs on FDI. Various transmission channels have been identified, in particularly for low-income countries. This study enlightens policymakers about the policy on creating a conducive and sustainable environment for IPRs in order to encourage FDI inflows to their countries.     

The impact of an accelerated depreciation tax policy on employment: Evidence from China

We examine the impact of an accelerated depreciation tax policy (ADP) on employment. As a tax incentive policy, we expect an ADP to impact firm behavior significantly, but its effect on employment remains uninvestigated. Leveraging the two-stage implementation of an ADP in selected industries in China in 2014 and 2015 and using a difference-in-differences research design, we find that: 1) the ADP significantly increases employment, which is consistent with the output effect hypothesis; and 2) the ADP increases firms’ labor demand, mainly by stimulating investment in fixed assets and easing their financial constraints. Additional analysis suggests that the impact of ADP on employment is more salient for small firms, non-state-owned firms, and high growth firms, and skilled labor employment, indicating that the ADP is more effective for firms with high financial constraints and hiring skilled labor to accompany the increase in capital investment.     

Importers,Exporters and Multinationals: Exploring the Hierarchy of International Linkages

The purpose of this paper is to empirically explore two dimensions of the firm hierarchy of international market-specific linkages, using data on Swedish manufacturing firms from 1997 to 2007. First, we investigate the productivity ordering with respect to three international linkages; importing, exporting and investing abroad. Second, we explore whether differences in the productivity ordering across industries correlates with industry and country characteristics. Our findings support a general productivity hierarchy from importing to exporting and from exporting to investing abroad, as well as from a low to a high number of linkages (measuring the complexity of firms’ international linkages). However, an industry-by-industry examination shows that the hierarchical structure is only generally upheld when it comes to the number of international linkages, while the ordering of import, export and investment linkages does not exhibit the same regularity across industries. Extending the analysis, we find that the lack of a hierarchical structure is more likely in industries focusing on larger and less distant markets.     

人口老龄化必然导致资本替代劳动吗

经济学理论认为,人口老龄化会导致劳动力成本上升,从而改变企业的要素结构、通过资本替代劳动的方式应对,但不同类型的企业对老龄化做出的反应可能存在差异,需要进行深入分析。文章利用中国工业企业数据对上述问题进行了研究,实证结果显示：整体来看,人口老龄化显著提高了企业的资本劳动比,但资本劳动比的上升并不一定表现为资本对劳动的替代。在规模较大、融资约束较轻的企业,老龄化促使其用固定资产投资替代了劳动,但在规模较小和融资约束程度较为严重的企业,人口老龄化并没有显著提高其固定资产投资,只是缩小了其劳动力雇佣规模,说明企业规模和融资约束是影响企业要素结构升级的重要因素。此外,文章还发现人口老龄化主要促使企业利用资本替代低技能劳动力,而人口老龄化的资本替代劳动效应在资本密集型、生产率水平较高和非出口企业中更为显著。文章从微观企业投资视角拓展了人口老龄化的经济效应的研究范畴,并通过规模效应和融资约束角度分析了制约工业企业提高智能化生产程度的因素,从而对传统的见解提供了有益的补充。文章的研究结论能够为政府制定积极应对人口老龄化和助力企业要素结构升级的相关政策提供经验证据的支持。     

The Impact of Multinational Presence on Domestic Investment: Firm‐Level Evidence from South Korea

In order to analyze the effects of foreign multinationals' presence on domestic firms' investment, we use a detailed firm level data set from South Korea for the 2006–2014 period. We combine it with the input‐output tables provided by the Bank of Korea to construct industry level measures of multinational presence in sectors that are horizontally and vertically linked, and estimate dynamic investment equations that are augmented with these foreign presence measures. We find a positive and significant effect of foreign presence in both horizontally and vertically linked industries on domestic firm's investment rate, with larger effects arising from multinational presence in the supplying sectors. Quantitatively, a 2 percentage point increase in the presence of multinational suppliers increases the domestic firm's investment rate by 3.24 percentage points. We also find that this effect is larger for small and medium firms, private firms, nonexporters, firms that are not part of a chaebol, and for firms in external finance dependent industries. A similar 2 percentage point increase in the foreign presence in downstream sectors increases the investment rate of domestic suppliers by 0.55 percentage points. This effect is larger if the domestic firm is part of a chaebol, or is in a less external finance dependent industry. Investment increase by 0.53 percentage points following a 2 percentage point increase in horizontal linkages.     

International Standards for IP Protection and R&D Incentives Revisited

Aoki and Prusa (1993), Journal of International Economics, examine the effects of differing standards of IPRs protection on the R&D intensity of home country firms. This paper builds on this work by examining the R&D outcomes of home country firms when foreign rivals imitate rather than innovate. In infant industries, full commitment to discriminatory protection always leads to the most R&D. In mature industries, full commitment to discriminatory protection leads to reduced R&D intensity. This contrasts with the dynamic case where discriminatory protection, by relaxing a binding cash in advance constraint, leads to more R&D than does uniform protection.     

Effects of Knowledge Spillovers on Knowledge Production and Productivity Growth in Korean Manufacturing Firms

Using Korean firm‐level data, this paper studies the effects of knowledge spillovers on knowledge production and productivity growth. Data from 213 Korean firms for the years 1985 to 2007 are used, and the number of patent applications is used as a proxy variable for knowledge. The results show that all the growth rates of output, patents, and productivity are higher in high‐technology firms. Regression results show that the spillover effect on knowledge production and productivity growth is very significant, and that the spillover effect is larger in small firms than in large firms. Moreover, spillover effects on productivity growth are larger after 1995, when Korean intellectual property rights were strengthened. Our findings suggest that the effects of knowledge spillover on productivity are positively correlated with strong intellectual property rights.     

Firm Productivity and Mode of Foreign Expansion: Evidence from Taiwanese Manufacturing Firms

This paper builds on the recent literature on firm heterogeneity in international trade and foreign direct investment (FDI), and aims to empirically examine how firm productivity affects a firm’s foreign market entry strategy beyond the simple binary choice between exporting and FDI. Utilizing the panel data of Taiwanese manufacturing firms during 2002–2012, we further classify FDI methods by whole ownership or a joint venture to investigate a firm’s foreign expansion decision. By performing Kolmogorov–Smirnov (KS) tests, we find that if a firm is more productive, it is more likely to choose FDI rather than exporting. However, productivity of firms choosing whole ownership is not so different from choosing a joint venture. Furthermore, a more productive firm is more likely to conduct both whole ownership of the foreign subsidiary and a joint venture formation in the case of FDI.     

Spatial Spillovers from Foreign Direct Investment: Evidence from the Yangtze River Delta in China

This paper examines the spatial externality from foreign direct investment on domestic firms. Using Chinese firm‐level data for 2004, and after accounting for an endogeneity problem, we find that foreign firms generate a significantly positive spillover effect on the regional productivity of domestic firms in similar counties and industries. Estimating a spatial‐autoregressive model, we further show that such local spillovers could transmit to domestic firms in other counties and industries through interactions among domestic firms. However, these spatial multiplier effects decline with distance, thereby reducing the foreign direct investment spillover effects for domestic firms in distant locations.     

The value-added tax reform and labor market outcomes: Firm-level evidence from China

The tax incentives designed to stimulate firm investment may have a large and unexpected impact on labor market outcomes. Using a comprehensive data set on Chinese manufacturing firms during the period 1998–2007 with a difference-in-differences approach, we examine the impact of the value-added tax reform in 2004 on the firm-level labor market outcomes. We find that firms in eligible industries and pilot regions (treated firms) enjoying lower costs of purchasing fixed assets under the reform tended to increase capital investment and reduce employment simultaneously relative to firms that did not have tax incentives (the control firms). Compared with the control firms, the treated firms became more capital intensive but had declines in labor share in value added and average wage. We also find that the employment adjustment is associated with increase in the share of skilled workers in terms of engineers and technicians, but not workers with a college degree or higher.     

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.     

The effects of credit lines on cash holdings and capital investment: Evidence from Japan

This study examines how credit lines affect corporate cash holdings and capital investment using a hand-collected data on publicly traded Japanese firms from 2006 to 2017. The study compares firms with and without credit lines to investigate the effects of credit lines. The empirical results are as follows: (1) Firms with credit lines hold smaller cash reserves than those without; (2) Firms with credit lines undertake more capital investment than those without; (3) The effects of credit lines are more amplified for financially constrained firms than their counterpart; (4) A close bank–firm relationship plays a positive role in the effect of credit lines on corporate activities.These empirical findings indicate that credit lines can improve firms’ financial flexibility and allow them to use cash holdings held for precautionary reasons to invest. The results also show that credit lines and the attendant implicit bank–firm relationships are complementary to each other. Moreover, having both credit lines and a close bank–firm relationship is important to Japanese firms for their corporate activities. Furthermore, the results imply that the use of credit lines is still relatively undeveloped in Japan, which may be a reason for the country's large corporate savings and lackluster investment.     

日本对华直接投资的新发展、新特点及其对策

新世纪以来,日本对华直接投资经历了快速增加、下降徘徊和再增加的过程,出现了一些新的特点。目前,尽管日资企业在中国面临知识产权保护和法制不完善等方面的问题,撤出和迁移的企业有所增加,但日本企业继续看好中国经济前景特别是看好中国大市场的潜力,以中国为中心开展海外事业的基本姿态并未改变,出现了一些有利于对华直接投资发展的新动向。为此,我国应该有针对性地采取积极的政策措施,促使日本企业改变对华直接投资"雷声大雨点小"的现状,既扩大投资规模,又改善投资质量,全面提升日本对华直接投资的规模和档次。     

Elasticities of derived demand under different objectives of the firm

Conclusions We have reconciled and generalized earlier comparisons of input demand elasticities under different objective functions of the firm. In general little can be said of the relative magnitudes of the elasticities under different objectives, since different goals usually imply different levels of production and input demand. With some simplifying assumptions about the technology we can conclude that a profit-constrained, utility-maximizing firm tends to have higher input demand elasticities than a profit-maximizing firm facing the same cost and demand functions. This tendency is reinforced by a high profit requirement, decreasing returns to scale and slowly falling demand elasticity for the output. The results may help to explain differences in the stability of employment between industries,. Scherer [1980, pp. 365–67] reports that some studies have found an inverse relation between market concentration and stability of employment, which is contrary to the expected result. One may argue that in concentrated industries the firms are likely to have organizational slack or to face an inelastic product demand curve. Hence demand for factors of production should be less elastic than in more competitive industries. We have shown, however, that deviations from profit maximization may lead to higher input demand elasticities. Since non-profit-maximizing goals are likely to be more common in concentrated industries, the observed instability of employment may be partly due to the high elasticity of derived demand. Although the type of alternative goals studied in this paper may not be realistic in practice, the analysis shows nevertheless that goals of the firm may be one factor in explaining differences in the stability of employment.
