IPR Law Protection and Enforcement and the Effect on Horizontal Productivity Spillovers from Inward FDI to Domestic Firms: A Meta-Analysis

Christopoulou, D., Papageorgiadis, N., Wang, Chengang, Magkonis, G. 20 April 2021 (has links)
Yes / We study the role of the strength of Intellectual Property Rights (IPR) law protection and enforcement in influencing horizontal productivity spillovers from inward FDI to domestic firms in host countries. While most WTO countries adopted strong IPR legislation due to exogenous pressure resulting from the signing of the Trade-Related Aspects of IPR (TRIPS) agreement, public IPR enforcement strength continues to vary significantly between countries. We meta-analyse 49 studies and find that public IPR enforcement strength has a direct positive effect on horizontal productivity spillovers from inward FDI to domestic firms and a negative moderating effect on the relationship between IPR law protection strength and horizontal productivity spillovers from inward FDI to domestic firms.

Investigating The Effect of Technological Innovation on Countries' Green Production Capabilities Evolution and Spillover

Alhaddad, Hanin 01 January 2024 (has links) (PDF)
This dissertation presents a novel methodology to examine the evolution of green production capabilities for 226 countries between 2003 and 2017 based on spillovers between the sectors. It identifies the growth potential of sectors and the key sectors driving the spillovers of production capabilities. Moreover, it delves into the patterns observed in the evolution of these capabilities, considering the diverse economic classifications. Lastly, it focuses on 72 developing countries that face unique challenges in pursuing green economic growth, exploring the effect of technological innovations on the spillovers of production capabilities within their green sectors. Three key hypotheses are investigated: the first is how non-green production capabilities significantly contribute to the spillovers of production capabilities into green sectors. Second is how spillovers of production capabilities from the green sectors follow a path-defying evolution pattern, while those from the non-green sectors adhere to a path-dependent evolution. Third is how technological innovations have a positive and significant effect on the spillovers of existing non-green production capabilities into green sectors but have no significant effect on the spillovers of production capabilities between green sectors. Using a novel methodology, the 'Green Sector Space,' statistical analysis, and Partial Least Square Structural Equation Modeling, the findings highlight significant disparities in green production capabilities in developing economies compared to other economic classifications. Additionally, non-green sectors' significant and dominant role in driving the spillovers of production capabilities into the green sectors, with a significantly higher dominance observed in developing countries. Finally, the results underscore how technological innovations have a significant and positive effect on the spillovers of production capabilities from non-green to green sectors in developing countries, which exhibits a path-dependent evolution pattern. Conversely, does not affect the spillovers between the green sectors. Recommendations are also provided in developing countries to leverage technological innovations in accelerating their green growth.

Three essays on knowledge diffusion from academic-based research / Três ensaios sobre a difusão do conhecimento da pesquisa acadêmica

Soares, Thiago José Cysneiros Cavalcanti 26 February 2019 (has links)
Universities around the world are increasingly engaging in activities of technology transfer, intensifying knowledge flows of academic-based research to firms. It is expected that these institutions play an active role in the development of the local economy. In fact, there was a sharp rise in patenting activities by universities over the last years. Moreover, universities have used different mechanisms to support university-industry technology transfer, as for example the implementation of regulatory frameworks and the creation of internal organizations aimed at facilitating interactions with firms. Although prior studies have comprehensively increased our understanding of the ways in which academic knowledge is disseminated, several important questions remain open. In this sense, the purpose of this dissertation is to investigate how university technologies are disseminated to firms, also examining the relationship between idiosyncratic attributes of universities, their regional context and university-industry technology transfer. The essays in this dissertation build on the knowledge spillover and technology transfer literatures, addressing different dimensions of the diffusion of academic knowledge. The dissertation consists of a general introduction, three essays, and a conclusion. The first essay relies on US patent databases, whereas the second and third use data in the context of Brazilian universities. Each essay, from a different perspective, explores dimensions that have not yet been addressed by prior literature. Investigating the dissemination patterns of technological knowledge embedded in university inventions is critical to understanding how and under circumstances scientific research disseminates and is deployed by firms. Along this line, this dissertation contributes to the field of innovation and technology management in several ways. / Universidades ao redor do mundo estão cada vez mais envolvidas em atividades de transferência de tecnologia, intensificando os fluxos de conhecimento da pesquisa acadêmica para empresas. Espera-se que essas instituições desempenhem um papel ativo no desenvolvimento da economia local. De fato, houve um crescimento significativo nas atividades de patenteamento por parte de universidades nos últimos anos. Além disso, as universidades têm utilizado diversos mecanismos para apoiar atividades de transferência de tecnologia, tais como a implementação de regulamentações e a criação de organizações internas destinadas a facilitar as interações com empresas. Embora estudos passados tenham ampliado de forma abrangente a nossa compreensão sobre a disseminação do conhecimento acadêmico, várias questões fundamentais permanecem em aberto. Desse modo, o objetivo desta tese é investigar como tecnologias acadêmicas são disseminadas para empresas, examinando também a relação entre atributos idiossincráticos das universidades, seu contexto regional e atividades de transferência de tecnologia. Os capítulos que seguem se baseiam nas literaturas de spillovers de conhecimento e transferência de tecnologia, abordando diferentes dimensões da difusão do conhecimento acadêmico. Esta tese consiste em uma introdução geral, três capítulos e uma conclusão. O primeiro capítulo baseia-se em dados de bases de patentes americanas, enquanto o segundo e terceiro usam dados no contexto de universidades brasileiras. Cada capítulo, de uma perspectiva diferente, explora dimensões que ainda não foram abordadas pela literatura. A investigação dos padrões de disseminação do conhecimento tecnológico embutido em invenções acadêmicas é fundamental para o entendimento de como e sob quais circunstâncias a pesquisa científica é disseminada e utilizada por empresas. Desse modo, esta tese contribui para o campo da inovação e gestão da tecnologia de diversas maneiras.

[pt] HABITAÇÃO INFORMAL, SPILLOVERS ESPACIAIS E ACESSO AO MERCADO DE TRABALHO NO BRASIL / [en] INFORMAL HOUSING, SPATIAL SPILLOVERS, AND LABOR MARKET ACCESS IN BRAZIL

ANDRE NASCIMENTO ALCANTARA PEREIRA 25 May 2022 (has links)
[pt] Neste trabalho, estudo a oferta e demanda por habitação na Região Metropolitana de São Paulo, uma das principais cidades do Brasil. Usando dados detalhados de deslocamento ao trabalho, eu estimo um modelo quantitativo espacial, no qual agentes tomam decisões sobre local de residência e trabalho com base em aluguéis, salários, custos de deslocamento e amenidades. Proponho uma extensão do arcabouço usual com um setor formal de oferta de moradia para incluir também um setor informal em competição, uma importante característica institucional presente em diversos países em desenvolvimento. Eu quantifico os spillovers espaciais associados ao setor informal e investigo seu papel em prover residentes com melhor acesso ao mercado de trabalho local. / [en] In this work, I study the supply and demand for housing in the São Paulo Metropolitan Area, a major city in Brazil. Using detailed commuting data, I estimate a quantitative spatial model, in which agents make decisions on residence and workplace based on local rents, wages, commuting costs, and amenities. I propose an extension of the usual framework with a formal housing supply sector to include a competing informal one, an important institutional characteristic present in many developing countries. I quantify the spatial spillovers of this informal housing, and investigate its role in providing residents with improved access to the local labor market.

Auditor-provided non-audit services in listed and private family firms

Dobler, Michael 11 July 2023 (has links)
Purpose – The aim of this paper is to provide evidence on the extent and the consequences of the provision of non-audit services (NAS) by statutory auditors to German family firms. Design/methodology/approach – The study analyzes hand collected fee data of 368 listed and private family firms in Germany. It employs univariate tests, ordinary least squares and two-stage least squares regressions to investigate potential threats to perceived auditor independence and knowledge spillovers between jointly provided NAS and audit services. Findings – Incumbent auditors are shown to be a significant source of various types of NAS to family firms. There is weak evidence on threats to perceived auditor independence and support for reciprocal knowledge spillovers between the services. While listed and private family firms do not differ in regard to the proportion of NAS fees, comparative findings suggest that key threats and benefits of jointly provided services are more prevalent among private than among listed family firms. Research limitations/implications – The study suffers from limited data availability and is restricted to the initial year of mandatory audit fee disclosure of private firms in Germany. Particularities of family firms and the German setting, as well as differential results for listed and private family firms, suggest fruitful avenues for future research. Practical implications – The study addresses the current issues in audit regulation. Regulatory bodies should consider that key threats and benefits of auditor-provided NAS decrease with stronger exogenous restrictions. Attempts to restrict jointly provided services in the EU suggest family firms to reconsider their reliance on auditors as a trusted source of NAS. Originality/value – This study is the first to provide evidence on the extent and consequences of auditor-provided NAS in family firms based on fee disclosure. It is also among the few studies that investigate private firms in a code law country and complements prior evidence from Germany that is restricted to listed firms. More generally, it contributes to limited evidence at the intersection of audit and family business research.

The impact of knowledge capital on regional total factor productivity

LeSage, James P., Fischer, Manfred M. 04 1900 (has links) (PDF)
This paper explores the contribution of knowledge capital to total factor productivity differences among regions within a regression framework. The dependent variable is total factor productivity, defined as output (in terms of gross value added) per unit of labour and physical capital combined, while the explanatory variable is a patent stock measure of regional knowledge endowments. We provide an econometric derivation of the relationship, which in the presence of unobservable knowledge capital leads to a spatial regression model relationship. This model form is extended to account for technological dependence between regions, which allows us to quantify disembodied knowledge spillover impacts arising from both spatial and technological proximity. A six-year panel of 198 NUTS-2 regions spanning the period from 1997 to 2002 was used to empirically test the model, to measure both direct and indirect effects of knowledge capital on regional total factor productivity, and to assess the relative importance of knowledge spillovers from spatial versus technological proximity.

Estimates and inferences of knowledge capital impacts on regional total factor productivity

LeSage, James P., Fischer, Manfred M. 07 1900 (has links) (PDF)
This paper explores the contribution of knowledge capital to total factor productivity differences among regions within a regression framework. We provide an econometric derivation of the relationship and show that the presence of latent/unobservable regional knowledge capital leads to a model relationship that includes both spatial and technological dependence. This model specification accounts for both spatial and technological dependence between regions, which allows us to quantify spillover impacts arising from both types of interaction. Sample data on 198 NUTS-2 regions spanning the period from 1997 to 2002 was used to empirically test the model, to measure both direct and indirect effects of knowledge capital on regional total factor productivity, and to assess the relative importance of knowledge spillovers from spatial versus technological proximity.

Three essays on the macroeconomic impact of foreign direct investment in low and middle income countries

Abdullah, Md. 15 February 2017 (has links)
This dissertation comprises three essays on macroeconomic impacts of foreign direct investment (FDI). The first essay analyses the impact of FDI on the growth rate of total factor productivity of host countries. The essay focuses on 77 low- and middle-income countries and is based on balanced panel data for the period 1980-2008. The system GMM and common correlated effects (CCE) panel data methods are applied to estimate the models. Estimated coefficients show that FDI does not have any significant impact on the growth rate and the levels of TFP. The second essay investigates the relationship between FDI and domestic investment focusing on low- and middle-income countries, and using panel data for the period 1980-2012. It applies common parameter and heterogeneous parameter, static and dynamic, single equation and simultaneous equation panel data econometric techniques to study the relationship. Empirical findings suggest that FDI crowds our domestic investment. Our estimated coefficients also suggest that countries that have weak institutions, less developed financial systems, less human capital, less developed infrastructure, or economies that are more open, are more exposed to foreign competition and experience stronger crowding out from inward FDI. In the third essay, the influence of capital flows on the real exchange rate of recipient countries is analysed. The influence of three important capital flows, viz. foreign direct investment (FDI), foreign aid, and remittances, are assessed on the real exchange rate, using data for 45 middle- and low-income countries for the period 1980–2013. Both heterogeneous and homogeneous panel data methods are applied to estimate the real exchange rate models. The estimated coefficients of these models imply that foreign direct investment (FDI) and remittances do not influence the real exchange rate. Aid tends to depreciate the real exchange rate. Findings also suggest that financial development does not influence the exchange rate impact of aid in our sample countries. The study further finds that while aid tends to increase real exchange rate volatility, FDI and remittances do not have any robust influence on volatility. / February 2017

contributions a l'économie de la publicité / contibutions to the advertising economy

Ben Elhadj-Ben Brahim, Nada 13 October 2011 (has links)
Nous nous proposons, dans le cadre de cette thèse d'examiner des modèles économiques dans lesquels les firmes ont recours à différentes approches de publicité. Nous analysons les effets des investissements et des tarifs publicitaires sur les stratégies des annonceurs et des médias et nous étudions les différentes configurations de marché qui émergent à l'équilibre. Nous nous focalisons dans les Chapitres 2, 3 et 4 sur la publicité informative ciblée. Dans les chapitres suivants nous considérons que la publicité est persuasive et qu'elle peut créer des externalités aussi bien positives que négatives.Ces externalités peuvent être exogènes comme c'est le cas dans le Chapitre 5 ou endogènes (Chapitre 6).Plus précisément, nous examinons, dans le Chapitre 2, dans le cadre d'une différenciation horizontale, la concurrence en prix et en publicité informative ciblée. Dans le Chapitre 3, nous caractérisons l'équilibre d'un média qui a le choix entre éditer un seul journal général publié dans deux localisations géographiques ou bien éditer un journal local dans chaque localisation, donnant ainsi la possibilité aux annonceurs d'acheter des espaces publicitaires séparés dans chaque édition ou un package publicitaire pour les deux éditions. Nous posons dans le Chapitre 4 le problème du signal de la qualité d'une firme qui lance un nouveau produit, dont la qualité n'est pas connue par les consommateurs potentiels. La firme signale sa qualité à travers une publicité informative ciblée en choisissant la taille du marché niche. L'objectif du Chapitre 5 est de mettre en évidence les interactions directes qui existent entre le marché des médias et le marché des producteurs en considérant que le marché est caractérisé par des externalités de publicité aussi bien positives que négatives. Dans le dernier chapitre, nous étudions les incitations de deux firmes, différenciées par la qualité, à investir dans deux types de publicité : une publicité comparative et une publicité non-comparative. / In this thesis, we develop economic models in which firms invest in different types of advertising. We analyze the effects of the advertising investments and prices on the advertisers and media strategies. In addition, we study the various market configurations emerging at equilibrium. On this basis, we focus, in Chapters 2, 3 and 4, on the targeted informative advertising. In the following chapters, we consider persuasive advertising that create negative and positive externalities. These externalities may be exogenous (Chapter 5) or endogenous (Chapter 6).More precisely, we investigate in Chapter 2, through a horizontal differentiation framework, the price competition and targeted advertising investments when firms are able to perfectly target each type of consumer. In Chapter 3, we model a situation in which a printed media has the choice between editing a single national newspaper published in two cities, or editing two local newspapers allowing thus advertisers to buy separated or bundled ads. In Chapter 4, we investigate the best signalling strategy of a monopoly when introducing a new product with unobservable quality. The firm signals its quality to the potential consumers through informative targeted advertising i.e. by choosing the size of the reached consumer's market. The aim of chapter 5 is to highlight the strategic interaction between media and product markets when the market exhibits positive and negative advertising externalities. The last Chapter is interested in the optimal persuasive advertising and pricing decisions of two vertically differentiated firms given that each firm has the choice to advertise in comparative and/or non-comparative advertising.
