Una visión económica del subsistema portuario sur

Con la reforma de la Ley de puertos en diciembre de 1997, que aumentó las competencias de las comunidades autónomas en la gestión de los puertos, cobra vigencia el estudio de los sistemas portuarios regionales. Esta comunicación examina la realidad económica de los puertos andaluces y cual es su impacto en nuestra economía regional. Para ello se recogen los resultados de los principales estudios de impacto económico de los puertos andaluces, que utilizando la metodología input-output se han realizado en los últimos años. Tras analizar las principales magnitudes del subsistema portuario andaluz, se estima cual es la especialización funcional de los puertos andaluces, así como el grado de integración de estos puertos.After the reform of port’s law in December 1997 which increased Spanish autonomous regions’ competencies in port management, it is necessary to study regionalist port systems. This paper analyses the economic situation of Andalucias’ ports, and its impact on our economic. That’s why the results of the most important impact studies about Andalucias’ ports have been collected. These studies have been done for the last few years and they are based on input-output methodology. The main Andalucia ports’ magnitudes have been studied, then the functions of those ports and their grade of integration have been estimated

The city-airport connection in the low-cost carrier era: Implications for urban transport planning

This article, examines differences between the behavior of passengers of low-cost and network airlines when choosing their transport mode for travel to airports. It is found that a passenger flying with a low- cost carrier is 6% less likely to take a taxi to the airport, but more than 4% more likely to drive a rented car and 2% more likely to use public transport than a user of a network carrier

How can the effects of the introduction of a new airline on a national airline network be measured? A time series approach for the Ryanair case in Spain

This paper quantifies the Ryanair Effect on the Spanish airline network. It proposes new methodology based on an advanced time series approach that allows both the direct and indirect effects of the incorporation of a new airline to be measured and that can be easily extrapolated to other airport systems. The findings show the mean indirect effect on other airlines, in absolute value, is 8.6 per cent of the total airport traffic, peaking at a maximum of almost 29 per cent. Also, surprisingly, there is found to be a negative indirect effect at only four of the ten airports analysed

Do more trucks lead to more motor vehicle fatalities in European roads? Evaluating the impact of specific safety strategies.

Truck operations have recently become an important focus of academic research not only because road freight transport is a key part of logistics, but because trucks are usually associated with negative externalities including pollution, congestion and traffic accidents. While the negative environmental impacts of truck activities have been extensively analyzed, comparatively little attention has been paid to the role of trucks in road accidents. A review of the literature identifies various truck-traffic safety related issues: frequency of accidents and their determinants; risk factors associated with truck driver behavior (including cell phone use, fatigue, alcohol and drugs consumption); truck characteristics and facilities (roadway types, specific lanes and electronic stability programs) to improve performance of vehiclemaneuvering; and the safety characteristics of heavy and large trucks. However, to date, there seems to have been developed few studies evaluating the complex coexistence of trucks and cars on roads and that may support the implementation of differential road safety strategies applied to them. This paper focuses on the impact on the traffic fatalities rate of the interaction between trucks and cars on roads. We also assess the efficiency of two stricter road safety regulations for trucks, as yet not harmonized in the European Union; namely, speed limits and maximum blood alcohol concentration rates. For this, econometric models have been developed from a panel data set for European Union during the years 1999–2010. Our findings show that rising motorization rates for trucks lead to higher traffic fatalities, while rising motorization rates for cars do not. These effects remain constant across Europe, even in the most highly developed countries boasting the best highway networks. Furthermore, we also find that lower maximum speed limits for trucks are effective and maximum blood alcohol concentration rates for professional drivers are only effective when they are strictly set to zero. Therefore, our results point to that the differential treatment of trucks is not only adequate for mitigating an important source of congestion and pollution, but that the implementation of stricter road safety measures in European countries for the case of trucks also contributes significantly to reducing fatalities. In summary, and as a counterpoint to the negative impact of trucks on road traffic accidents, we conclude the effectiveness of efforts made in road safety policy (based on specific traffic regulations by vehicle type imposed by member States) to counteract the safety externalities of freight transportation in the European Union. In certain sense, our study might provide indirect support to public policies implemented at the macro European level to promote multimodal transport corridors. In this respect, there is an increasing focus at the European level on how freight transport can be moved from trucks on roads to more environmentally-sustainable modes, such as rail and ship.Dirección General de Tráfico SPIP2014127

The europeanization of the common road safety policy: an econometric analysis

The 2001 White Paper and its development in the 3rd European Road Safety Action Program, represent a turning point in the history of the European Road Safety Policy. The possible determinants of the road mortality in the EU over (2000-2009) are examined using a panel data. Our main finding is the negative effect and statistical significance of the Europeanization variable (the number of years that a country has been in the EU). By this variable, we test the effectiveness of EU programs to save lives in road accidents according to the years that each country has been in the EU

The relationship between public and private bicycle use: the case of Seville

Despite the success achieved by Public Bicycle Sharing Systems (PBSS) across the world, several researchers provide evidence on their limitations and constraints in a medium-long term, and bicycle ownership may be considered as a complementary tool to promote a 'bicycle-culture'. This paper aims to cover the gap about the interaction between both systems (public bicycle / private bicycle) and which are the key aspects to explain the bicycle-buying decision. After a fieldwork based on surveys conducted in Seville (Spain), one of the cities currently acknowledged worldwide for its successful policy of promoting cycling, we apply a Discrete Choice Model. Our findings show that among the socio-demographic factors that favor the move from the PBSS to the private bicycle are: having a higher level of education, being more progressive ideologically-speaking, and being a resident of the city itself; while age and gender do not appear to be conclusive. Experienced users, for whom the bicycle is a part of his /her healthy lifestyle, state a greater willingness to buy a bicycle. And the main obstacles to make the jump from the PBSS to the private bicycle, and that any action plan to support private bicycle usage should take into account, are: the lack of proper parking at the origin/destination, and fear of theft

At a time of insurgent parties, can societies believe in election polls?. The Spanish experience

The main purpose of this paper is to use the Spanish case, through an econometric analysis of 226 electoral polls, to explain why polls are making more mistakes in times of great socioeconomic slumps, political instability and the emergence of new political parties. In this context, it is the very instrument with which society tries to reduce the reigning uncertainty that, paradoxically, can ultimately drive uncertainty up. Our results show that the prediction error for the new emerging parties is significantly higher than for the traditional parties and this error is not sensitive to solutions for increasing the reliability of surveys, such as increasing sample size, transparency constantly conducting periodical surveys, the closeness of the approaching election or the survey mode that is used. It can be observed that pollsters do not want to make predictions that vary greatly from the average of the other polls. Finally, editorial bias appears to play a significant role, especially in the case of traditional parties.El principal objetivo de este artículo es explicar por qué las encuestas electorales cometen más errores en épocas de crisis económica, inestabilidad política y con partidos emergentes como Podemos y Ciudadanos. Para ello utilizamos una base de datos de 226 encuestas previas a las elecciones generales españolas de 2016. En este contexto, paradójicamente vemos como el instrumento que la sociedad utiliza para reducir su incertidumbre puede acabar aumentándola. Nuestros resultados muestran como el error de predicción de los nuevos partidos es significativamente mayor que los tradicionales e insensible a las soluciones clásicas para aumentar la precisión de las encuestas, como el tamaño de la muestra, el método de muestreo, la experiencia del encuestador, o la proximidad de la cita electoral. Además, se observa que las empresas que desarrollan las encuestas realizan de forma sistemática predicciones muy próximas a las que han realizado las encuestas recientes de sus competidores. Finalmente, el sesgo editorial parece ser una variable relevante, especialmente en lo relativo a las predicciones de los partidos tradicionale

Who is the charter passenger? Characteristics and attitudes of the leastknown passenger

Despite the fact that charter flights have become a hybrid model between the low-cost carriers and the network carriers, the charter passenger’s profile presents important differences from those of the passengers of the other two types of airline. This article analyses those differences. The authors use a multinomial logit model and a broad database of almost 40,000 passengers. Their results break with certain stereotypical assumptions, such as that charter passengers are low-income, that they use the services of travel agencies to a greater degree, or that they show a clear bias for travel for vacation purposes. Their profile is of infrequent flyers with a longer waiting time before boarding, although this does not mean that they make more purchases at the airport. Furthermore, they look to travel to more remote destinations, with no intermediate stopovers, which are not usually served by the low-cost carriers, as a result of which they have a greater presence at hub airports.Ministerio de Economía y Competitividad ECO2012-3697

Measuring the LCC effect on charter airlines in the Spanish airport system

Using a robust transfer function model methodology, the present paper seeks to offer empirical evidence regarding the size and type of effects that low-cost carriers (LCCs) have had on traffic for charter carriers (CCs) in the Spanish airport system by geographic market. We show an unmistakable substitution relationship between CCs and LCCs in the latter’s typical niche markets, national and European flights, while there is no reaction from the CCs in the segment of international flights outside the EU. Furthermore, substitution effects are smaller between CCs and LCCs on the domestic level than effects between LCCs and network carriers (NCs) and slightly larger on the European level. Lastly, CC traffic’s different sensitivity to terrorist attacks, day of the week, air accidents and the economic crisis is also evident. CCs should therefore be considered an independent category that warrants individualized analyses
