    Varieties or Qualities? Horizontal and Vertical Intra-industry Trade within the NAFTA Trade Bloc

    This article investigates empirically the nature and the dynamics of intra-regional trade in North America. Specifically, we analyze intra-NAFTA patterns of horizontal and vertical intra-industry trade - H(V)IIT - in the United States, Canada and Mexico over the 1992-2002 period and examine some industry characteristics of observed IIT patterns for each IIT component. The results indicate that though HIIT and VIIT exhibit different trends, both IIT types are important in labour/resource-intensive sectors, suggesting that comparative advantage may be an important factor in intra-NAFTA IIT. The most striking finding is that HIIT is consistently increasing, while VIIT exhibits a significant downward trend. Hence, our findings suggest that intra-NAFTA IIT has increasingly become an exchange of different varieties rather than different qualities, indicating to some extent an economic convergence process within the NAFTA trade bloc.International Relations/Trade,

    Determinants of Export Specialization in ICT Products: A Cross-Country Analysis

    Get PDF
    In this paper the determinants of ICT export specialization are investigated with a panel- econometric analysis, which includes 28 countries. ICT exports are broken down into three broad ICT product groups (electronic data processing machines, integrated circuits and electronic components, and telecommunications equipment), and the determinants are examined for each of the above product categories. Our results indicate that technology factors, such as Research & Development expenditure and human capital constitute significant determinants. However, other deterministic factors, related to more recent trade theories, seem to be relatively more important.Export specialization, Information and Communications Technology (ICT), ICT exports, Panel data analysis

    Sindicatos griegos : entre crisis y austeridad

    El objetivo del presente artículo es proporcionar explicaciones sobre la incapacidad de los sindicatos griegos para hacer frente al desafío de austeridad impuesto a Grecia por la Troika y sus Memorandos tras el rescate de mayo de 2010. Para entender por qué los principales actores sindicales respondieron a la crisis de la forma en que lo hicieron, llevaremos a cabo un análisis de su trayectoria. Más concretamente, las elecciones sindicales en términos tanto de posiciones políticas como de acciones concretas se explican a la luz del sistema sindical griego y de la lógica que se estableció en respuesta a importantes cambios en el marco legislativo de principios de los años noventa; a saber: la introducción de trabajo flexible y la aprobación de la ley sobre negociaciones colectivas libres y otras disposicionesThe aim of the present chapter is to provide explanations of the Greek trade unions’ inability to cope with the austerity challenge, which was imposed on Greece by the Troika and its Memoranda in the aftermath of the bailout of May 2010. In order to understand why the main trade union actors responded to the crisis in the way they did, we shall carry out a path-dependent analysis. More specifically, the trade union choices in terms of both political stances and concrete actions are explained in light of the Greek trade union system and logic that was established in response to important changes in the legislative framework of the early 1990; namely, the introduction of flexible labour and the approval of Bill on Free collective bargaining and other provisions

    Agglomeration or Dispersion? Industrial Specialization and Geographic Concentration in NAFTA

    Get PDF
    We analyze industrial specialization and geographic concentration patterns within the NAFTAregional integration area during 1988-2000 and examine the determinants of spatial concentration. Theresults indicate that NAFTA countries have become increasingly dissimilar over time. A changing spatialstructure of total NAFTA manufacturing is also evident. Manufacturing is increasingly relocating toMexico, which comes at the expense of the US. In addition, there is evidence of a general upward trendin the degree of relative geographic concentration of North American industries. Labor-intensive andlow-technology activities appear to be the most spatially concentrated industries, exhibiting a strongincreasing trend. Comparative advantage factors largely explain geographic concentration of industriesacross NAFTA countries, indicating the empirical relevance of traditional trade theory in the NAFTAcase

    An interpretable wildfire spreading model for real-time predictions

    Forest fires pose a natural threat with devastating social, environmental, and economic implications. The rapid and highly uncertain rate of spread of wildfires necessitates a trustworthy digital tool capable of providing real-time estimates of fire evolution and human interventions, while receiving continuous input from remote sensing. The current work aims at developing an interpretable, physics-based model that will serve as the core of such a tool. This model is constructed using easily understandable equations, incorporating a limited set of parameters that capture essential quantities and heat transport mechanisms. The simplicity of the model allows for effective utilization of data from sensory input, enabling optimal estimation of these parameters. In particular, simplified versions of combustion kinetics and mass/energy balances lead to a computationally inexpensive system of differential equations that provide the spatio-temporal evolution of temperature and flammables over a two-dimensional region. The model is validated by comparing its predictions and the effect of parameters such as flammable bulk density, moisture content, and wind speed, with benchmark results. Additionally, the model successfully captures the evolution of the firefront shape and its rate of spread in multiple directions
