Trade in capital goods generated by international diffusion of technology

This paper examines the dynamics of national income of developing countries, which must import advanced capital goods so as to use technology which has been learned. The main result is that depending on foreign countries for capital goods has no negative effects on real wage rates, which are determined solely by labour productivity of indigenous industries. The analysis also covers the mechanism of export-oriented growth of developing countries and its effects on developed countries. All of the explanations are quite simple, however, none of them can be derived if international learning or trade in capital goods is ignored.     

Catching up to the technology frontier: the dichotomy between innovation and imitation

Abstract Using data for 55 developing and developed countries, this research examines the roles of technology transfer, research intensity, educational attainment, and the ability to absorb foreign technology in explaining cross‐country differences in productivity growth. The results show that innovation is an important factor for growth in OECD countries, whereas growth in developing countries is driven by imitation. Furthermore, the interaction between educational attainment and the distance to the frontier is a significant determinant of growth in the overall sample.     

Vertical technology transfer and the welfare implications of patent protection

Significant amount of vertical technology transfer occurs between developed and developing-country firms, and many trading companies from developing countries create competition in the developed countries, yet the literature on intellectual property rights did not pay considerable attention to these aspects. In a Cournot oligopoly with vertical technology transfer, we show that patent protection in the developing country raises developed-country welfare if the following three conditions hold together: (i) patent protection in the developing country deters entry in the final goods market, (ii) the marginal cost difference between the incumbent and the entrant final goods sellers is sufficiently small, and (iii) the marginal cost difference between the incumbent and the entrant developing-country producers is sufficiently high. We also show that patent protection in the developing country always creates higher developing-country welfare if no developing-country firm enters the final goods market. We also discuss the implications of Bertrand competition on our results.     

Imitation and innovation driven development under imperfect intellectual property rights

Developing countries employ about two-fifth of the world's researchers, originate one quarter of world expenditures on R&D, and their inventions are subject to imitation. Nevertheless, the previous literature focuses on North–South setups in which the South is restricted to imitating northern inventions. To analyze the effects of IPR policies on developed and developing countries, we extend this literature to allow not only for southern innovation and imitation of northern goods, but also for imitation targeted at southern innovations. We find the effects of IPRs on R&D and welfare to be non-monotonic and dependent on innovation efficiency and an innovation threshold in the South. For sufficiently strong IPRs the South engages in original R&D and stronger IPRs promote southern innovation, welfare, and a reduction in the North–South wage gap. Below the threshold, a strengthening of IPR protection fails to promote innovation and decreases welfare. Stronger IPRs exclusively for southern firms can benefit both regions by shifting southern resources from the imitation of northern goods to original southern innovation.     

企业家技术进步路径选择与经济增长

发达国家的知识和技术进步速度越快,发展中国家越是能收到技术模仿的好处,从而带来较高的经济增长率。越是接近技术前沿的发达国家,创新型企业家的作用越大,离技术前沿越远的发展中国家,模仿型企业家的作用往往更明显。发展中国家的企业家通过知识过滤、吸收、模仿、"干中学",不断积累人力资本和物质资本,为自主创新积蓄力量,最终能实现模仿式创新和自主创新的良性互动。     

Aggregate Fluctuations with National and International Returns to Scale*

Cyclical movements in aggregate output, factor inputs, and productivity are all positively correlated across countries. This article proposes a model in which positive cross‐country correlations of these variables result from increasing returns to the world‐wide variety of intermediate goods even if technology shocks are purely country‐specific. The model also accounts for the observed positive relationship between bilateral trade volume and international comovements. Positive comovements can also arise with constant returns to variety, but only if technology shocks are themselves strongly correlated. The combination of constant returns and common shocks, however, tends to generate procyclical fluctuations of the trade balance.     

Catch-up and fall-back through innovation and imitation

Will fast growing emerging economies sustain rapid growth rates until they “catch-up” to the technology frontier? Are there incentives for some developed countries to free-ride off of innovators and optimally “fall-back” relative to the frontier? This paper models agents growing as a result of investments in innovation and imitation. Imitation facilitates technology diffusion, with the productivity of imitation modeled by a catch-up function that increases with distance to the frontier. The resulting equilibrium is an endogenous segmentation between innovators and imitators, where imitating agents optimally choose to “catch-up” or “fall-back” to a productivity ratio below the frontier.     

Trade‐related intellectual property rights: industry variation and technology diffusion

Abstract This paper assesses how a strengthening of intellectual property rights (IPRs) affects international technology diffusion by altering the volume of high‐tech exports into developing countries. A simple North‐South general equilibrium model in which industries differ in their imitation rates is developed. Stronger IPRs encourage Northern firms in a wider range of industries to start exporting. Exports in industries with the highest risk of imitation rise, while exports in other industries may fall. More technology diffuses to the South because new high‐tech products are introduced in the Southern market. This works against the reduction in technology diffusion caused by limited imitation.     

International Technology Diffusion and the Growth of TFP in the Manufacturing Sector of Developing Economies

This paper evaluates various channels through which foreign technology diffuses to the manufacturing sector of developing economies. These economies undertake virtually no own R&D, so they rely on foreign technology to a much larger extent than developed economies. We investigate the direct effect of foreign R&D, as well as technology embodied in imports of intermediate and capital goods and foreign direct investment, on the growth of total factor productivity and value added in the manufacturing sector of 32 economies during 1965–92. We find that foreign R&D typically has the biggest positive impact on domestic productivity and value‐added growth. Imports of capital goods and foreign direct investment also play a similar role, but their effect is of smaller magnitude and is not always significant.     

International Technology Transfer: Who Gains and Who Loses?*

When one country has a superior technology in all commodities, a Ricardian model with two goods and two countries is used to examine uncompensated transfers of superior technology in one or both goods. A transfer of the superior but second‐best technology always benefits the advanced country because it was improting that good initially and now gets it cheaper. But the free gift of the first‐best technology can also benefit the advanced country if a certain productivity condition is satisfied because that country may now export its former import good at an even better terms of trade.     

中国进口商品结构 及与贸易伙伴的关系研究

本文在对230种制成品按技术含量分类的基础上,利用最新的数据计算了中国进口技术结构的历史变迁与现状、19个国家和地区向中国的出口结构以及中国与贸易伙伴的相互依赖关系。研究结果表明：在1995-2011年期间,低技术含量制成品、中等技术含量制成品在中国进口中所占份额下降,初级制成品、资源型制成品、高技术含量制成品所占份额上升,高技术含量制成品早在2000年之前就超过中等技术含量制成品成为了中国第一大进口商品;不同类型国家及地区向中国出口的商品类型不同,它们在中国进口中的地位也不同;中国与日本、韩国、中国台湾之间的相互依赖关系都比较大,中国与美国、德国、法国、荷兰的相互依赖度比较小,中国进口对发展中大国、新兴发展中国家及地区的依赖程度都小于这些国家及地区出口对中国的依赖程度,中国是发展中大国、新兴发展中国家及地区的主要出口国。总的来说,中国对外贸易进口的发展具有共享性、包容性,不仅带动了发展中国家及地区的出口,还促进了发达国家的出口。     

Product variety and technical change

Motivated by growth models based on the variety of capital goods, recent empirical studies have established links between productivity and several trade-based measures of product variety, carrying the implication that these measures may represent technology. We study this implication by explicitly proposing the variety of capital goods available for production as a direct measure of the state of technology. Within a simple growth and development framework, we derive a ‘conditional technological convergence’ hypothesis on how this variety should behave if it were indeed to represent the state of technology. The hypothesis is tested with highly disaggregated trade data, using tools from the income convergence literature. The results suggest that a trade-based count measure of the variety of available capital goods, allowing for product differentiation by country of origin, indeed behaves ‘as if’ it represented technology when change of technology is understood as a learning process, and that there is conditional technological convergence among our panel of mainly OECD and transition economies.     

International technology diffusion and economic growth: Explaining the spillover benefits to developing countries

Technology spillovers offer great opportunities for economic growth to developing countries that do little, if any, R&D activity. This paper explores the extent to which these countries benefit from foreign technology, the diffusion mechanisms involved, and the factors that shape their absorption capabilities. Results based on a non-stationary panel of 55 developing countries indicate that the benefits are quite substantial: a ten-percent increase in foreign R&D stock is translated into more than a two-percent increase in aggregate productivity. Of the diffusion channels considered, imports appear to be more conducive to R&D spillover. In addition, developing countries that enjoy larger benefits tend to exhibit larger stock of human capital, more openness to trade and foreign activities, and stronger institutions. These North–South R&D spillovers, although larger than previously suggested, appear less strong than North–North spillovers, adding to the general literature on economic divergence between developed and developing countries.     

Technology shocks around the world

This article investigates the effects of a permanent technology shock on labor input in the major seven developed countries. The recent empirical literature which uses Structural Vector Autoregressions (SVAR) with long-run restrictions has argued that technology shocks lead to a persistent and significant decline in employment in most of the G7 countries. We claim that the international transmission of shocks prevents the use of existing SVAR models, but also suggests alternative specifications to properly uncover their effects. We show in a quantitative two-country model that a measure of labor productivity aggregated across countries is more immune to persistent, if not permanent, shocks and allows to accurately identify the responses of the labor input to a technology shock. Using labor productivity at the G7 aggregate level, we find that the response of employment changes critically in most of the major seven developed countries.     

知识产权保护、技术差距与发展中国家的技术进步

本文基于南北技术扩散的分析框架探讨了发展中国家的知识产权保护、技术差距对发展中国家技术进步的影响.不同于以往研究,本文假定发展中国家同时进行自主创新和国外先进技术模仿,其知识产权保护在鼓励自主创新和国外技术模仿的两难中权衡取舍.理论分析结果显示发展中国家的知识产权保护、技术差距都对其技术进步都有重要影响.实证检验结果表明,我国当前的技术进步主要依赖于对国外先进技术的模仿,自主创新的技术进步效应不显著.因此现阶段鼓励国外技术模仿的宽松的知识产权保护政策有利于促进我国的技术进步,但随着我国与发达国家的技术差距不断缩小,自主创新能力不断提升,实行严格的知识产权保护将会有利于促进我国的技术进步.     

Multinational public goods provision under multilateral income transfers and productivity differences

This article examines multinational public goods provision under multilateral income transfers and productivity differences across countries. Under a planner who uses linear approximation for utility maximization, we show that (1) a country is an income receiver if it has a higher productivity than the average in producing public goods, enabling it to provide more public goods; (2) the amount of transfers can be pinned down for all countries with an adjustment cost; (3) each country obtains an identical utility increment; and (4) the country with the lowest adjustment cost is the best candidate for the planner country. All results are derived based on well-known information regarding the cost of producing the public goods and income levels.     

A model of trust in quality and North–South trade

Why do some countries produce higher quality goods than other countries? This paper suggests that one reason is self-perpetuating reputations, modelling the idea with a Klein–Leffler reputation model embedded in a general equilibrium model of trade. Reputation differences are particularly interesting because reputation is a form of “social capital”. Like product differentiation, it can explain why countries might trade even if their technologies and endowments are identical, why firms could profit from exports even if the foreign price is no higher than the domestic one, and why governments like to have “high-value” sectors. Ideally, a developing country would shift its own producers to a high-quality equilibrium; if that is not possible, the next best thing is to import experience goods and substitute to home production of goods for which reputation is not important.     

What drives cross-country differences in export variety? A bilateral panel approach

A worldwide event like the 2020 Coronavirus outbreak can only reinforce the interest in modelling trade diversification as a key factor in countries’ vulnerability to external shocks. This paper adopts a detailed relative framework to study the determinants of product-level export variety in a large bilateral panel of developing and developed economies (16,770 country pairs in the period 1988–2014). We find that country pairs characterized by large differentials in productivity and in the makeup of the labour force differ in export variety patterns. This result holds after controlling for other endowments and for trade costs. Further, productivity plays a significant role in the reduction of export variety dissimilarities between countries belonging to different income groups. Hence, without successful technological convergence the low-income economies will not be able to reduce their exposure to export risk.     

Competition policy in open economies

Abstract

This paper examines aspects of R&;D spillovers across countries, in particular, the role of international trade and human capital as the catalysts for international diffusion of technology. We present a new way of measuring foreign R&;D stocks embodied in foreign intermediate goods and capital equipment, which we argue is free from the criticism of previous measures. With the pooled panel data spanning 1970 through 1995 for 103 countries, we find that the effects of foreign R&;D on total factor productivity growth of both industrial countries and developing countries are substantial and that human capital is the most influential channel for absorbing foreign R&;D spillovers.     

Real Exchange Rate Trends and Growth: A Model of East Asia

In contrast to the Balassa–Samuelson hypothesis, many fast-growing Asian countries have experienced little trend real exchange rate appreciation, or even depreciation. Moreover, their long-run real exchange rate trend seems to be dominated by movements in traded goods prices. A model is developed which is consistent with these observations. As in the Balassa–Samuelson model, productivity growth is concentrated in the traded goods sector. Nevertheless the real exchange rate may exhibit trend depreciation, driven by persistent deviations in the price of traded goods from those in the reference country. The key feature of the model is the presence of endogenous productivity growth in the distribution services sector.
