Using panel VAR to analyze international knowledge spillovers

Technology diffusion often plays a critical role in models of trade and economic growth. Most existing empirical tests for international technology spillovers suggest some role for spillovers in explaining productivity growth. It has been relatively difficult, however, to identify separate roles for the direct and indirect channels of knowledge spillovers. The influence of these channels is often confounded owing to the focus on total‐factor productivity (TFP) and R&D spending within a cross‐section or panel data setting. This paper employs an alternative methodology to investigate the role of direct knowledge spillovers. Using citation‐weighted domestic patents, citation‐weighted foreign patents and value added for 14 U.S. manufacturing industries over the period 1977 to 2004 a panel VAR methodology is employed to investigate the dynamic role of direct and indirect knowledge spillovers. Evidence for the role of the direct knowledge spillovers channel is found—an increase in citation‐weighted patents abroad directly increases the measure of domestic citation‐weighted patents, after accounting for the influence of productivity/value added. The role of foreign innovative activity, however, is small relative to the role of U.S. innovative activity in explaining the dynamics of industry value added.     

An empirical study on FDI international knowledge spillovers and regional economic development in China

This article has constructed a framework to analyze the relationship between national innovation investments, international knowledge spillover due to FDI and regional technological progress. We use the panel data sample in 1992–2006 from China’s 29 provinces (municipalities or autonomous regions) to test the impact of China’s regional R&;D investments, international knowledge spillovers of FDI on its regional technological progress. It reveals that the local investments in science and technology are the most important factors to promote technological progress; for the structure and quality of China’s current FDI, the knowledge spillover effects from FDI, especially through the FDI enterprises’ manufacturing activities, are not obvious; the local gains in its technology development from FDI depends on its economic and technological level. Based on the above conclusions we give the corresponding policy recommendations for China’s FDI policy and regional economic development.

中国拉美石油能源战略与拉美石油能源国有化

我国自20世纪90年代以来实施的拉美石油能源战略已经初现成效,但近年来,拉关一些主要产油国的石油能源国有化对我国拉关石油能源战略产生了强烈的冲击。因此,我国拉关石油能源战略在实施中应注重经济关系改善,巩固和扩大市场;淡化政治,突出合作的企业行为;采取多种战略组合开发模式,提高规避和抗击各类风险的能力。     

Human capital and international knowledge spillovers in TFP growth of a sample of developing countries: an exploration of alternative approaches

This study tests and compares the two major approaches to the modelling of human capital in growth regressions, i.e. the Lucas and the Nelson-Phelps approach, in the context of developing country models with international knowledge spillovers. On balance, the results seem to favour the Nelson-Phelps approach. Using human capital stock variables instead of flow variables, a positive role for human capital in the absorption of international knowledge spillovers other than embodied R&D spillovers is confirmed. The results suggest the importance of distinguishing between different types of international knowledge spillovers, as well as between different human capital sub-categories.     

Convergence clubs in Latin America

The aim of this work is to identify convergence clubs in 17 Latin American countries in terms of GDP per capita during the period 1990–2014. To do this, we apply the methodology developed by Phillips-Sul in order to identify the different convergence clubs on the path of growth in the Latin American economy over this period. The empirical results strongly support the existence of convergence clubs, indicating that the Latin American economy consists of four groups, each converging towards its own steady-state path, with two countries being divergent.     

Closing the Technological Gap in Latin America

A main implication of C.E. Ayres tool-combination principle is that the goal of technical progress is best served by a non-proprietary, open science public policy. Joseph Schumpeter claimed that new combinations are consequential only when they have been successfully commercialized. The capacity to privatize knowledge is, moreover, a powerful stimulus to innovation. This paper reexamines the Ayresian and Schumpeterian positions using evidence from the Bayh Dole experiment. The Bayh Dole Act, which gave universities title to inventions resulting from federally-sponsored research, created a laboratory wherein the trade-offs between diminution of the appropriable knowledge fund (due to patenting) and incentives to commercialization can be appraised.     

North-South knowledge spillovers and competition: convergence versus divergence

Technology spillovers from high-productivity countries in the North allow low-productivity countries in the South to improve productivity in high-tech sectors relatively easy. However, the South's share in world goods markets for high-tech products is relatively low, which reduces opportunities for learning by doing. Our simple Ricardian endogenous growth model shows how the balance between toughness of competition in trade and the strength of North-South spillovers determines whether productivity levels diverge, partially converge or fully converge in the long run. If convergence prevails, the North is confronted with declining employment in high-tech sectors. Temporary (trade) policy measures can turn a diverging economy into a converging one.     

The future of the future: Strategic foresight in Latin America

With few differences in timing, future studies in Latin America were initiated with a linear conception of reality. Orchestrated with techniques such as the Delphi, future studies were supported by mathematical principles of probability. Several countries have surpassed this stage while moving into strategic foresight. Strategic foresight analyzes the future as a multiple reality. In other words, it means thinking differently and not reading reality in a linear manner. It means accepting that there is not one future but several futures and that one question could have more than one answer.This change has demanded a shift in mentality. The presence of the disciplines in universities is of vital importance. For example, the Technological Institute of Monterrey (Mexico) and the Universidad Externado de Colombia (Bogota) offer foresight and strategy programs at the graduate level.This article describes how different individuals, groups, agencies and institutions in Latin America have emerged thanks to the support provided by the science and technology governmental agencies of each country. The author provides examples from different countries including Colombia, Brazil, Chile and Mexico. Currently, strategic foresight is slowly gaining recognition and acceptance as a compass for productive sectors and as a generator of competitiveness.However, despite the contributions of strategic foresight, Latin American countries, with the exception of some of the above-mentioned countries, have struggled to take off into the future. The role of strategic foresight can become the driving force behind this awakening, if the challenge of linking global trends with local contextualization through scenarios is accepted.     

Severance Payment Programs in Latin America

Latin America stands out among different regions in the world for her high employment termination costs. To this contribute both a high level of severance payments and the existence of overlapping benefits. The effectiveness of these protective measures, however, is limited by the size of the informal sector, which, in turn, may be related to employment protection levels. Another important limitation on the effectiveness of employment protection regulation is the often large transaction costs associated with making good of law provisions for the worker. Equilibrium severance pay levels may thus be well below what law mandates as evidence of low coverage rates and undesirable side effects is mounting, reform seems a critical policy issue. However, this reform cannot focus exclusively on severance pay, but it has to incorporate other overlapping benefits, such as UISAs, and advance notice. It also has to contend with a problematic political economy. Jaramillo is a Senior Researcher at the Group for Analysis of Development, GRADE. Saavedra is with the World Bank.

The Capitalist Revolution in Latin America

This article argues that the business enterprise has evolved through successive stable organizational structures which correspond with instability for those falling outside its aegis. This is shown in the institutional and historical context of both managerial capitalism in the mid-twentieth century as well as the era of financialization that followed. Hence, the framework developed herein elaborates on the ceremonial characteristics of the business enterprise under money manager capitalism, and constitutes a contribution toward an updated going concern theory of the business enterprise.     

Microfinance Control Fraud in Latin America

Over the past three decades, the global microfinance industry has witnessed phenomenal growth in terms of the numbers of borrowers and the total gross loan portfolio outstanding. An application of the criminologists' perspective and Black's theory of control fraud to the global microfinance industry reveals a high degree of overlap between the common characteristics of control frauds and the characteristics of the microfinance industry and suggests that the sector provides a criminogenic environment suitable to Ponzi-type dynamics, including an imperative of growth, misrepresentation of financial and operating performance, a reputation for integrity and innovativeness, concentration in unregulated markets and areas most conducive to accounting fraud, non-transparency and secrecy, dubious accounting methods, lobbying in favor of deregulation, attempts to suborn controls such as accountants, lawyers, regulators, and rating agencies, executive use of the company for personal gain, excessive risk taking at the expense of investors' capital, warnings raised but ignored, and, finally, inevitable collapse. Regulatory interventions are needed to prevent predatory lending and over-indebtedness of poor microfinance borrowers in Latin America and elsewhere. Such regulation, while necessary to protect the poor, is not well liked by the investment community as it places microfinance institutions under local scrutiny, reduces the profitability of the sector, and limits opportunities for control fraud.     

China's Economic Influence in Latin America

After decades of low‐level commercial interaction, China and Latin America significantly ramped up their economic relationship in the 2000s. China has jumped to first place as an export destination for many countries, and it is a major source of imports for all countries in the Latin America/Caribbean region. While not a major source of foreign direct investment overall, China has built a strong investment presence in certain countries, particularly in the natural resource and infrastructure sectors. China's influence in Latin America has presented a great opportunity for many countries, but it has also brought new risks. Three main challenges face the region: how to mitigate the impacts of increased commodity concentration as a result of China's strong demand for natural resources; how to avoid other natural resource curse effects; and how to manage the tapering of this growth. Latin American countries' relationships with China vary widely, so there is no single, coordinated regional response.     

Spectrum allocation in Latin America: An economic analysis

As elsewhere, wireless markets play a crucial role in Latin American economic growth. Mobile telephone networks increasingly provide the communications infrastructure that has largely been lacking throughout the region. Yet, governments have generally made only modest allocations of bandwidth available to Latin American wireless operators, either absolutely (in terms of spectrum each country could allocate at modest opportunity cost) or relative to countries in North America, Asia and the European Union. Using an empirical model estimated on mobile phone data for international markets, we show that very large social benefits are available to countries that make more spectrum available for mobile phone markets. We conduct simulations using our calibrated model to provide lower bounds for country-by-country gains from larger allocations. We also discuss the impact of alternative regulatory regimes on the feasibility to achieve those social gains.     

Firm-level productivity in Latin America and the Caribbean

While the accumulation of factors of production, both physical and human capital, has helped Latin America and the Caribbean (LAC) to narrow the income gap with developed economies, aggregate productivity is still relatively low. Although there are numerous determinants of aggregate productivity, it is largely based on the underlying productivity of all firms in the economy. Using firm-level data from several waves of the World Bank Enterprise Survey and Chile's National Manufacturing Survey, we explore the ‘what’ question on productivity dispersion in LAC. We document three stylized facts: (i) there are significant differences in firm productivity within industries – the firm at the 90th percentile of the productivity distribution produces almost seven times as much output (using the same measured inputs) as the 10^th percentile firm; (ii) productivity differences persist over time – regressing a firm's current productivity on its one-year lagged productivity yields an autoregressive coefficient of around 0.9; and (iii) most of the growth in aggregate productivity comes from improvements in the productivity of existing firms.     

International knowledge spillovers in the wind power industry: evidence from the European Union

The purpose of this paper is to analyze the presence of international knowledge spillovers in the wind power sector. Specifically, the paper investigates whether successful invention efforts in one country, measured by way of granted wind power patent counts, have had positive effects on the neighboring countries’ abilities to generate patents of the same category. Data on the number of patents granted at the European Patent Office during the period 1978–2008 are used for the eight national technological leaders in the western European wind power sector. The few comprehensive wind power studies that exist have only found limited evidence of international knowledge spillovers. However, in this paper, we find that international spillovers are statistically significant determinants of a country’s wind power patenting outcomes. Geographical distance is also taken into consideration, and the knowledge spillover effects are shown to become stronger with decreases in this distance. The results should have important policy implications, for example, for a national government when it comes to applying an investment strategy in wind power or, alternatively, free-riding on other countries’ invention efforts.
