La actividad hidrocarburífera en la Cuenca del Golfo San Jorge : El papel del empresariado regional

La política económica que se implementó en la década de 1990 tuvo como eje, entre las principales medidas, la apertura de la economía, la privatización de las empresas públicas, el desmantelamiento del aparato estatal y sus agentes reguladores, el ajuste fiscal y del gasto público tanto a nivel nacional, como provincial y municipal, la retirada del Estado Nacional como inversor y subsidiador de actividades económicas, la desregulación del mercado de trabajo y la concentración en grupos 'oligopólicos' de las principales actividades productivas, lo que produjo diferentes impactos en las distintas actividades económicas de la Región Patagónica, dependiendo de su inserción en el mercado interno y externo. En este trabajo se pretende, a partir de una descripción de la evolución de la actividad petrolera y de un estudio de caso, analizar los factores que viabilizan el desarrollo económico local y repensar el papel de los actores sociales en relación con el contexto y con las posibilidades de establecimiento de estrategias de innovación en las sociedades locales. En la primera parte del artículo se hace una caracterización socioeconómica de la región de la Cuenca del Golfo San Jorge. A continuación se observa la evolución de la actividad petrolera dentro de la cuenca, su papel en el mercado de trabajo y su requerimiento de mano de obra; se realiza una caracterización de los principales actores y de su relación con el desarrollo local. En la parte final del artículo se intenta mostrar los desafíos que enfrentan los actores públicos y privados vinculados con la actividad petrolera y su proyección en el corto y mediano plazo

Economic restructuring and regional distrubution of enterprises in Vietnam

The change in the ownership structure of enterprises was one of the major features of the Vietnamese economy in the 2000s. Of the three sectors of state, private and FDI, the state sector, which employed the majority of enterprise workers at the beginning of the 2000s, became the smallest by the end of the decade. One of the factors contributing to such phenomenon was SOE restructuring. Earlier SOE restructuring in the early 1990s is said to have resulted in increased economic inequality among provinces. The purpose of this paper is to clarify the impact of the SOE restructuring and related changes in the ownership structure of enterprises on the regional distribution of economic activities in the 2000s.

Non-conventional provisions in regional trade agreements : do they enhance international trade?

The scope of recent regional trade agreements (RTAs) is becoming much wider in terms of including several provisions such as competition policy or intellectual property. This paper empirically examines how far advanced, non-conventional provisions in RTAs increase trade values among RTA member countries, by estimating the gravity equation with more disaggregated indicators for RTAs. As a result, we find that the provision on competition policy has the largest impacts on trade values, following that on government procurement. Our further analysis reveals that the more significant roles of these two provisions can be also observed in the impacts on the intensive and extensive margins.

Impacts of projected maximum temperature extremes for C21 by an ensemble of regional climate models on cereal cropping systems in the Iberian Peninsula

Crops growing in the Iberian Peninsula may be subjected to damagingly high temperatures during the sensitive development periods of flowering and grain filling. Such episodes are considered important hazards and farmers may take insurance to offset their impact. Increases in value and frequency of maximum temperature have been observed in the Iberian Peninsula during the 20th century, and studies on climate change indicate the possibility of further increase by the end of the 21st century. Here, impacts of current and future high temperatures on cereal cropping systems of the Iberian Peninsula are evaluated, focusing on vulnerable development periods of winter and summer crops. Climate change scenarios obtained from an ensemble of ten Regional Climate Models (multimodel ensemble) combined with crop simulation models were used for this purpose and related uncertainty was estimated. Results reveal that higher extremes of maximum temperature represent a threat to summer-grown but not to winter-grown crops in the Iberian Peninsula. The study highlights the different vulnerability of crops in the two growing seasons and the need to account for changes in extreme temperatures in developing adaptations in cereal cropping systems. Finally, this work contributes to clarifying the causes of high-uncertainty impact projections from previous studies.

Employment rate impacts of charging the Heavy Good Vehicle corridor (Madrid-Sevilla) across Spanish regions: a Random Utility Based Multiregional Input-Output approach

The implementation of a charging policy for heavy goods vehicles in European Union (EU) member countries has been imposed to reflect costs of construction and maintenance of infrastructure as well as externalities such as congestion, accidents and environmental impact. In this context, EU countries approved the Eurovignette directive (1999/62/EC) and its amending directive (2006 /38/EC) which established a legal framework to regulate the system of tolls. Even if that regulation seek s to increase the efficien cy of freight, it will trigger direct and indirect effects on Spain’s regional economies by increasing transport costs. This paper presents the development of a multiregional Input-Output methodology (MRIO) with elastic trade coefficients to predict in terregional trade, using transport attributes integrated in multinomial logit models. This method is highly useful to carry out an ex-ante evaluation of transport policies because it involves road freight transport cost sensitivity, and determine regional distributive and substitution economic effect s of countries like Spain, characterized by socio-demographic and economic attributes, differentiated region by region. It will thus be possible to determine cost-effective strategies, given different policy scenarios. MRIO mode l would then be used to determine the impact on the employment rate of imposing a charge in the Madrid-Sevilla corridor in Spain. This methodology is important for measuring the impact on the employment rate since it is one of the main macroeconomic indicators of Spain’s regional and national economic situation. A previous research developed (DESTINO) using a MRIO method estimated employment impacts of road pricing policy across Spanish regions considering a fuel tax charge (€/liter) in the entire shortest cost path network for freight transport. Actually, it found that the variation in employment is expected to be substantial for some regions, and negligible for others. For example, in this Spanish case study of regional employment has showed reductions between 16.1% (Rioja) and 1.4% (Madrid region). This variation range seems to be related to either the intensity of freight transport in each region or dependency of regions to transport intensive economic sect ors. In fact, regions with freight transport intensive sectors will lose more jobs while regions with a predominantly service economy undergo a fairly insignificant loss of employment. This paper is focused on evaluating a freight transport vehicle-kilometer charge (€/km) in a non-tolled motorway corridor (A-4) between Madrid-Sevilla (517 Km.). The consequences of the road pricing policy implementation show s that the employment reductions are not as high as the diminution stated in the previous research because this corridor does not affect the whole freight transport system of Spain.

Economic change, crime, and mortality crisis in Russia: regional analysis

Objective: To identify which aspects of socioeconomic change were associated with the steep decline in life expectancy in Russia between 1990 and 1994.

A Case Study of the Economic and Environmental Impacts from a Bio-fuel Facility (Southwest Georgia Ethanol, LLC) on the Surrounding Communities, Southwest Georgia

Bio-fuels such as ethanol provide an extraordinary opportunity to address our dependency on foreign oil. This case study examines the economic and environmental impacts associated with constructing and operating a dry mill ethanol manufacturing facility in a Southwest Georgia town and surrounding communities. The case study found that the plant had little impact on air quality, water quality, and habitat fragmentation. However, economic results showed the plant produced $1.5 million in tax revenues, and 86 jobs. Ethanol producers and communities must consider both the economic and environmental impacts on a local community when searching or attracting a bio-fuels plant. Likewise, communities should be aware of these challenges when attracting ethanol production plants.
