Foreign direct investment determinants revisited in the context of global value chains

In this paper, we aim at contributing to the new field of research that intends to bring up-to-date the tools and statistics currently used to look to the current reality given by Global Value Chains (GVC) in international trade and Foreign Direct Investment (FDI). Namely, we make use of the most recent data published by the World Input-Output Database to suggest indicators to measure the participation and net gains of countries by being a part of GVC; and use those indicators in a pooled-regression model to estimate determinants of FDI stocks in Organization for Economic Co-operation and Development (OECD)-member countries. We conclude that one of the measures proposed proves to be statistically significant in explaining the bilateral stock of FDI in OECD countries, meaning that the higher the transnational income generated between two given countries by GVC, taken as a proxy to the participation of those countries in GVC, the higher one could expect the FDI entering those countries to be. The regression also shows the negative impact of the global financial crisis that started in 2009 in the world’s bilateral FDI stocks and, additionally, the particular and significant role played by the People’s Republic of China in determining these stocks.

Inter-industry analysis and monetary policy evaluations in the Korean flow of funds accounts

This study mainly aims to provide an inter-industry analysis through the subdivision of various industries in flow of funds (FOF) accounts. Combined with the Financial Statement Analysis data from 2004 and 2005, the Korean FOF accounts are reconstructed to form "from-whom-to-whom" basis FOF tables, which are composed of 115 institutional sectors and correspond to tables and techniques of input–output (I–O) analysis. First, power of dispersion indices are obtained by applying the I–O analysis method. Most service and IT industries, construction, and light industries in manufacturing are included in the first quadrant group, whereas heavy and chemical industries are placed in the fourth quadrant since their power indices in the asset-oriented system are comparatively smaller than those of other institutional sectors. Second, investments and savings, which are induced by the central bank, are calculated for monetary policy evaluations. Industries are bifurcated into two groups to compare their features. The first group refers to industries whose power of dispersion in the asset-oriented system is greater than 1, whereas the second group indicates that their index is less than 1. We found that the net induced investments (NII)–total liabilities ratios of the first group show levels half those of the second group since the former's induced savings are obviously greater than the latter.

Undermined climate policies : a study on the impact of regulatory and financial discrimination across heterogeneous firms in China

Firms in China within the same industry but with different ownership and size have very different production functions and can face very different emission regulations and financial conditions. This fact has largely been ignored in most of the existing literature on climate change. Using a newly augmented Chinese input–output table in which information about firm size and ownership are explicitly reported, this paper employs a dynamic computable general equilibrium (CGE) model to analyze the impact of alternative climate policy designs with respect to regulation and financial conditions on heterogeneous firms. The simulation results indicate that with a business-as-usual regulatory structure, the effectiveness and economic efficiency of climate policies is significantly undermined. Expanding regulation to cover additional firms has a first-order effect of improving efficiency. However, over-investment in energy technologies in certain firms may decrease the overall efficiency of investments and dampen long-term economic growth by competing with other fixed-capital investments for financial resources. Therefore, a market-oriented arrangement for sharing emission reduction burden and a mechanism for allocating green investment is crucial for China to achieve a more ambitious emission target in the long run.

Productivity growth and the structure of production

In this study, interactions between potential hierarchical value chains existing in the production structure and industry-wise productivity growths are sought. We applied generalized Chenery-Watanabe heuristics for matrix linearity maximization to triangulate the input-output incidence matrix for both Japan and the Republic of Korea, finding the potential directed flow of values spanning the industrial sectors of the basic (disaggregated) industry classifications for both countries. Sector specific productivity growths were measured by way of the Trönquvist index, using the 2000-2005 linked input-output tables for both Japan and Korea.

Modelo de gestión del conocimiento para el impacto económico. Aplicación al sector defensa

En el escenario actual macro económico la toma de decisiones en materia económica de cualquier entidad pública debe de estar sustentada por una adecuada inteligencia económica. Es prioritario disponer de modelos, procesos, técnicas y herramientas que permitan garantizar un control adecuado de todas sus inversiones. En la presente tesis exponemos un modelo de gestión del conocimiento basado en el marco Input-Output (IO), que nos permite conocer el impacto económico de los programas públicos. Este modelo está soportado por un sistema de información que coadyuvará a los analistas económicos para la toma de decisiones en el campo de las inversiones públicas. El principal objetivo de la tesis es la creación y desarrollo de este modelo denominado MOCIE (Modelo del Conocimiento para el Impacto Económico). No obstante, en la tesis además de profundizar sobre este modelo y la gestión del conocimiento en materia económica de los grandes programas públicos, se ha realizado un estudio que ha abarcado diferentes líneas de investigación complementarias como el análisis IO, la ingeniería y la arquitectura de sistemas de la información, la economía de la Defensa o la computación genética. El modelo propuesto en esta tesis se ha puesto en práctica en un sector económico muy específico dentro de la economía nacional: el sector de la defensa. Por tanto, ha sido también necesario realizar un estudio en profundidad del propio sector y de la gestión de los programas públicos en el ámbito de la Defensa. MOCIE se estructura a través de tres capas de gestión del conocimiento que nos permiten, por un lado, la percepción de los componentes existentes en el entorno de las inversiones públicas y la comprensión de su significado en términos de impacto económico y su relación con el resto de variables macroeconómicas nacionales y, por otro, la proyección y monitorización de su estado a lo largo de todo el ciclo de vida de los programas públicos...

Thermally induced all-optical inverter and dynamic hysteresis loops in graphene oxide dispersions

We experimentally study the temporal dynamics of amplitude-modulated laser beams propagating through a water dispersion of graphene oxide sheets in a fiber-to-fiber U-bench. Nonlinear refraction induced in the sample by thermal effects leads to both phase reversing of the transmitted signals and dynamic hysteresis in the input- output power curves. A theoretical model including beam propagation and thermal lensing dynamics reproduces the experimental findings. © 2015 Optical Society of America.

La articulación productiva como elemento clave para el desarrollo económico: la experiencia de España, Corea del Sur y México frente al proceso de internacionalización de la producción, 1980-2000

La articulación productiva, como una característica esencial de la estructura económica, es un tema poco analizado por la teoría económica. Por lo tanto, esta tesis pretende incorporarla en el análisis económico de manera explícita, para estudiar los efectos que tienen sobre las características de las estructuras económicas la actual forma de organización de la producción y el comercio a nivel mundial. La investigación analiza las repercusiones de la producción fragmentada sobre las características de las estructuras económicas y los posibles efectos para el desarrollo económico. Se estudian tres países – Corea del Sur, España y México –, caracterizados por una fuerte integración internacional. Con el fin de evaluar el desempeño económico bajo modelos de desarrollo disímiles, se comparan el año de 1980 con al primer decenio del 2000, con el empleo de tablas input-output (TIO)...

Bienes de capital, flujos tecnológicos y cambio estructural: los casos de Estados Unidos, Japón y Alemania, 1980-2005

La innovación tecnológica se encuentra estrechamente vinculada con el desenvolvimiento de la estructura productiva. Durante mucho tiempo, esta relación era muy evidente, ya que la tecnología como fuente impulsora del crecimiento se asociaba a la inversión en maquinaria y equipo. Ésta última, integraba el componente de innovación que generaba el incremento en productividad. El modelo neoclásico ortodoxo centro el estudio del crecimiento económico en el estudio de Solow (1957), quien explica que la fuente del crecimiento se encuentra en un factor exógeno, que identifica como cambio tecnológico y, de esta manera, resta importancia a la inversión como un determinante del incremento en el producto. En consecuencia, los aportes teóricos recientes, particularmente el neoclásico, centran su atención en los factores que inciden en la generación y desarrollo de innovaciones, pero dejan de lado la vinculación con la estructura económica. En este trabajo se analiza la importancia de los bienes de capital en Alemania, Japón y Estados Unidos, empleando tablas input-output, durante 1980 y 2005, definiendo la vinculación entre cambio tecnológico y la estructura productiva. 1. Síntesis El objetivo es demostrar que la industria de bienes de capital vincula la dinámica tecnológica y los procesos de innovación con el desenvolvimiento de la estructura productiva, por ser clave en el desarrollo económico como fuerza motriz del sistema al generar cambio tecnológico, transferir innovaciones y articular el cambio tecnológico con la estructura productiva. De la Tesis se extraen los siguientes resultados: a) Desde una visión teórica Nathan Rosenberg justifica la importancia de los bienes de capital, por su capacidad de generar cambio tecnológico incorporado, así como por su carácter articulador con otros sectores productivos, favoreciendo el proceso de desarrollo económico. Por el lado metodológico, el análisis input-output resulta ser el más idóneo para el propósito de la investigación. b) La importancia del cambio tecnológico Mediante el estudio de patentes, se demostró que la dinámica de innovación del sector está relacionada con los flujos de conocimiento, al crear y difundir innovaciones, y por su habilidad de asimilar los avances generados en otros sectores. Con el empleo del “Análisis de Flujo Mínimo”, se determina que los bienes de capital juegan un papel destacado por sus efectos de propagación del esfuerzo innovador; asimismo, por ser generadores de innovaciones, su inversión en I+D se traduce en una alta capacidad para impactar a los sectores con los que se vincula...

Participation of portuguese manufacturing industry in global value chains

Portugal’s manufacturing sector has a significant importance both in national income and employment. As has been pointed out by several researchers, the traditional methods of analysis fail to grasp all the dimensions of economic competitiveness. This dissertation is then, at its core, an analysis of Portugal’s manufacturing industry in terms of the latter’s value added to production and impact to employment under the framework of global value chains. The current dissertation seeks to study in which way the Portuguese manufacturing industry, and its respective sectors, has a direct and indirect impact on the creation of value added and employment and how this impact can be measured. For development of this work the input-output approach for calculation of multipliers and the new framework proposed by Timmer et al. (2013) for calculation of GVC income and GVC jobs indicators were used, elaborated on the basis of the WIOD project dataset. Moreover, to illustrate the application of the provided methodology the Portuguese textile industry was used as an example. It was found that the changes in final demand of such sectors as Pulp, Paper, Printing and Publishing; Machinery, Nec and Textiles and Textile Products would have a larger impact on generated value added than other manufacturing sectors. At the same time, employment created by the changes in final demand would be more impacted by such sectors as Food, Beverages and Tobacco; Wood and Products of Wood and Cork and Textiles and Textile Products. In this regard, the number of low-skilled workers in Portugal seems to be more effected by changes in final demand, than those occupied by higher -skilled individuals. Moreover, it was found that the distribution of GVC income and GVC jobs for the Portuguese manufacturing industry shares a similar outlook. However, upon closer inspection of GVC labour distribution by skill levels there seems to exist a general progression in which low-skilled jobs requirements are met by local resources, while the need for higher skilled jobs require a greater “off-shoring” of work The results obtained through calculations of presented multipliers provide a powerful tool for policy makers in strategic planning of development of national economy. Using the provided methodology and obtained results, a government and supranational organizations could define which industry would have the greatest impact for an additional unit of output generated through the economy, and thus define the sectors for further investments.

Acerca da importância do primeiro quadrante da MIO-Alentejo

Chama-se a atenção para a importância fundamental (e sua possível utilização, em termos de políticas públicas de base regional) do primeiro quadrante da matriz input-output para a região Alentejo.

“Análise da Eficiência, Eficácia e Mortalidade Empresarial”

Este artigo analisa a eficácia e a eficiência do Programa Leader + e a mortalidade das empresas que beneficiaram de apoio financeiro no âmbito desta política pública, nas regiões Norte e Alentejo, no período de 2000 a 2006. A análise da eficácia e da eficiência incide sobre a totalidade dos projetos de investimento financiados e o estudo da mortalidade empresarial inclui apenas as empresas do sector privado, com atividade e/ou sede nas regiões citadas, que beneficiaram de financiamento. A avaliação da eficácia e da eficiência sustentou-se em indicadores de realização, indicadores de resultado e no rácio input-output. A sustentabilidade da política pública foi avaliada com base nas taxa de mortalidade das empresas e no estudo da relação entre a mortalidade empresarial e as variáveis região de pertença, atividade da empresa e número de sócios. O estudo permitiu encontrar diferenças entre as duas regiões ao nível da eficácia e da eficiência da política pública, bem como ao nível da mortalidade empresarial.

The Essays in International Trade and Finance

The first chapter provides the first evidence on the gross capital flows reactions to the financial sector reform. I establish four new stylized facts. First, the reform is associated with an average increase of 0.03pp in both gross capital flows. Second, immediately after the reform both flows decrease, in the long term they stabilize at a higher than the pre-liberalization levels. Third, the short term dynamics is governed by debt flows, while the long term dynamics are driven by all of the components. Finally, only a complex reform leads to a positive effect. The results are robust to a wide range of robustness checks. In the second chapter we develop a novel theory to explain the recent phenomenon of reshoring, i.e. firms moving back their previously offshored business activities. We firstly provide the evidence for the importance of the quality behind the reshoring decision and then, building on Antoniades (2015) we develop a dynamic heterogeneous firms model with quality choice and offshoring. In the dynamic setting the location decision entails a tradeoff between payroll and quality-related costs. In equilibrium reshoring arises as some firms initially offshore, exploit the increase in profits due to lower wages and finally return to the domestic country in order to further increase the quality. The third chapter provides the new evidence suggesting that selling through global production networks might lead to export upgrade. I relate the sector-level GVCs participation indicators derived from the international Input-Output Tables to the data on the unit values of exports at the product-exporter level. We find a strong association between the export prices and forward participation, in particular for the developing countries. We document also a less robust negative relationship between the GVCs backward participation and unit values of exports.

GENEOs, compactifications, and graphs

Our objective in this thesis is to study the pseudo-metric and topological structure of the space of group equivariant non-expansive operators (GENEOs). We introduce the notions of compactification of a perception pair, collectionwise surjectivity, and compactification of a space of GENEOs. We obtain some compactification results for perception pairs and the space of GENEOs. We show that when the data spaces are totally bounded and endow the common domains with metric structures, the perception pairs and every collectionwise surjective space of GENEOs can be embedded isometrically into the compact ones through compatible embeddings. An important part of the study of topology of the space of GENEOs is to populate it in a rich manner. We introduce the notion of a generalized permutant and show that this concept too, like that of a permutant, is useful in defining new GENEOs. We define the analogues of some of the aforementioned concepts in a graph theoretic setting, enabling us to use the power of the theory of GENEOs for the study of graphs in an efficient way. We define the notions of a graph perception pair, graph permutant, and a graph GENEO. We develop two models for the theory of graph GENEOs. The first model addresses the case of graphs having weights assigned to their vertices, while the second one addresses weighted on the edges. We prove some new results in the proposed theory of graph GENEOs and exhibit the power of our models by describing their applications to the structural study of simple graphs. We introduce the concept of a graph permutant and show that this concept can be used to define new graph GENEOs between distinct graph perception pairs, thereby enabling us to populate the space of graph GENEOs in a rich manner and shed more light on its structure.

Development and Automatization of a Planar Jet Wind Tunnel for the X-wire Calibration

The scope of this study is to design an automatic control system and create an automatic x-wire calibrator for a facility named Plane Air Tunnel; whose exit creates planar jet flow. The controlling power state as well as automatic speed adjustment of the inverter has been achieved. Thus, the wind tunnel can be run with respect to any desired speed and the x-wire can automatically be calibrated at that speed. To achieve that, VI programming using the LabView environment was learned, to acquire the pressure and temperature, and to calculate the velocity based on the acquisition data thanks to a pitot-static tube. Furthermore, communication with the inverter to give the commands for power on/off and speed control was also done using the LabView VI coding environment. The connection of the computer to the inverter was achieved by the proper cabling using DAQmx Analog/Digital (A/D) input/output (I/O). Moreover, the pressure profile along the streamwise direction of the plane air tunnel was studied. Pressure tappings and a multichannel pressure scanner were used to acquire the pressure values at different locations. Thanks to that, the aerodynamic efficiency of the contraction ratio was observed, and the pressure behavior was related to the velocity at the exit section. Furthermore, the control of the speed was accomplished by implementing a closed-loop PI controller on the LabView environment with and without using a pitot-static tube thanks to the pressure behavior information. The responses of the two controllers were analyzed and commented on by giving suggestions. In addition, hot wire experiments were performed to calibrate automatically and investigate the velocity profile of a turbulent planar jet. To be able to analyze the results, the physics of turbulent planar jet flow was studied. The fundamental terms, the methods used in the derivation of the equations, velocity profile, shear stress behavior, and the effect of vorticity were reviewed.

Modello di progettazione di una rete logistica per la consegna last-mile della merce in crowd-shipping

In questo lavoro si studierà un nuovo sistema di consegna merci, denominato crowd-shipping. Questo si propone come soluzione per il trasporto della merce a domicilio, soprattutto per quanto riguarda l’ultimo miglio, con la quale si intendono le consegne che vengono effettuate all’interno dei centri urbani. È una soluzione recente che prevede di appoggiare ai corrieri tradizionali delle persone comuni, definiti corrieri occasionali (OD, Occasional Drivers). Questi ultimi, percorrendo un tratto di strada per motivi personali, sono disposti a consegnare la merce ai destinatari finali effettuando delle deviazioni al loro tragitto originario, in cambio di un compenso. Dopo aver studiato la situazione attuale dell’E-commerce e dello sviluppo delle Sharing Economy, dopo aver appreso il funzionamento di questo nuovo tipo di soluzione logistica, verrà presentato un modello matematico di programmazione lineare per le consegne last mile della merce in crowd-shipping. Questo modello verrà testato nel contesto urbano di Bologna e prevedrà due livelli di consegna rappresentati in primis dai corrieri tradizionali e in secondo luogo dai corrieri occasionali. Modalità possibile grazie all’utilizzo di armadietti automatici come depositi intermedi; si avranno, infatti, dei corrieri classici che riforniscono gli armadietti e dei corrieri occasionali che prelevano la merce dagli armadietti e la consegnano ai destinatari finali. Il modello sarà implementato in scenari diversi, con un differente numero di attori coinvolti, diverse ricompense per gli OD e diverse tipologie di veicoli, più o meno inquinanti. Questo ultimo punto ci anticipa che questa modalità di consegne può portare benefici importanti anche a livello ambientale; e in un mondo dove i cambiamenti atmosferici dovuti all’inquinamento sono sempre più devastanti, il crowd-shipping può portare a benefici concreti. Benefici che si sono dimostrati anche economici, sia per le aziende di spedizioni, sia per i clienti finali.
