Measuring regional cohesion effects of large-scale transport infrastructure investments - an accessibility approach

Accessibility gains arising from transport infrastructure improvements are one of the key elements boosting a complex process involving transport, land use and regional development effects. The inclusion of the wider socio-economic effects stemming from large-scale transport infrastructure investments is uneven among national evaluation procedures, and there is no commonly accepted methodology to measure them. In addition, there are other effects which do not take into account the overall change in the value of a specific variable, -normally GDP or employment-, but only the changes in its spatial distribution. These distributive effects, related to spatial equity issues, are increasingly included as a policy objective in most infrastructure Master Plans. More over, at a European level, economic and social cohesion is considered among the priority objectives in the enlarged EU. However, the inclusion of cohesion effects in national assessment methodologies is quite limited. If cohesion issues are not taken into account, new infrastructure schemes may induce spatial polarising effects, as more profitable projects are usually the ones which interconnect central regions, at the expense of the relative position of peripheral regions. Moreover, each transport mode has its special features which make it more inclined towards cohesion or polarising effects. In this sense, recent studies at a European level on the impacts of RTE-T show that HSR lines seem to have rather polarising effects, while new road schemes seem to have slight cohesion effects. In this context, activity-based accessibility indicators can be used as a proxy to measure these distributive effects. Changes in the relative positions of the regions in terms of accessibility provide an estimate to test if the Master Plan increases or reduces disparities among regions- i.e. reduces or increases cohesion, respectively. The paper analyses these issues measuring the changes in accessibility stemming from the implementation of different high-capacity road and HSR schemes in Spain. Results show a slight cohesion effect after the implementation of the high-capacity road network, along with a polarising effect arising from the implementation of new HSR lines, in line with the results included in recent European- level studies. The paper is based on the work being carried out for the author’s Ph.D. Dissertation, titled: “Assessment of Transport Infrastructure Plans: a strategic approach integrating environmental, economic and spatial equity aspects”.

The Impact of Imports on Price-Cost Margins: An Empirical Illustration

This article decomposes the impact of imports on domestic price-cost margins into separate price and cost effects. Using data from 24 food-processing industries, the empirical results show that although the direct impact of imports on prices is always negative, a positive net impact on price-cost margins occurs in industries characterized by low own-price elasticity of demand and diseconomies of scale. Further results show that the disciplining effect of imports is more preponderant the lower the degree of domestic competition.Market power, imports, market structure, international trade, food industry, Agribusiness, Demand and Price Analysis, International Relations/Trade,

Optimal education and pensions in an endogenous growth model

It is well known that, in OLG economies with life-cycle saving and exogenous growth, competitive equilibria will in general fail to achieve optimality and may even be dynamically inefficient. This is a consequence of individuals accumulating amounts of physical capital that differ from the level which would maximize welfare along a balanced growth path (the Golden Rule). With human capital, a second potential source of departure from optimality arises, to wit: individuals may not choose the correct amount of education investment. However, the Golden Rule concept, widely used in exogenous growth frameworks, has not found its way into endogenous growth models. In this paper, we propose to recover the Golden Rule of physical and also human capital accumulation. The optimal policy to decentralize the Golden Rule balanced growth path when there are no constraints for individuals to finance their education investments is also characterized. It is shown that it involves positive pensions and negative education subsidies (i.e., taxes)endogenous growth, human capital, intergenerational transfers, education policy

On welfare criteria and optimality in an endogenous growth model

In this paper we explore the consequences for optimality of a social planner adopting two different welfare criteria. The framework of analysis is an OLG model with physical and human capital. We first show that, when the SWF is a discounted sum of individual utilities defined over consumption per unit of natural labour, the precise cardinalization of the individual utility function becomes crucial for the characterization of the social optimum. Also, decentralizing the social optimum requires an education subsidy. In contrast, when the SWF is a discounted sum of individual utilities defined over consumption per unit of efficient labour, the precise cardinalization of preferences becomes irrelevant. More strikingly, along the optimal growth path, education should be taxed.endogenous growth, human capital, intergenerational transfers, education policy

Spain, Water and Climate Change in COP 15 and Beyond: Aligning Mitigation and Adaptation through Innovation

The water/energy nexus opens a range of opportunities to align mitigation and adaptation framed by human security, which prioritises human development. In this context, Spain has an opportunity to play a leading role in realising this potential by pursuing a coherent multilevel strategy specifically designed for water and climate variability and change

Detailed and GlobalAnalysis of a Remedial Course's Impact on Incoming Students' Marks

Engineering incoming students are facing great difficulties to overcome first course subjects. To tackle that situation and increase the students’ success a Remedial course in Mathematics was offered to Informatics Engineering freshmen. This study presents a statistical analysis of their results comparing the marks obtained by those joining the course (studio group) versus those who did not participate (control group). ANOVA tests are performed over the students’ marks averages as well as over each subject students marks. These tests show statistically significant differences between both groups, with the studio group consistently outperforming the control group at 99% confidence level in most cases and at more than 92% confidence level in every case

Quality and Quantity of Sleep Study and its Relationship to the Performance of LPGA Tour Players

The relationship between sleep efficiency and elite level athletic performance that has a definitive and individual measure of performance (like golf, track, & swimming) has never been systematically studied. The extreme and rigorous travel schedules of professional golfers prevent consistent and necessary sleep schedules. The Ladies Professional Golf Association (LPGA) permitted Embry-Riddle Aeronautical University (ERAU) to ask for volunteers at two tournaments during October of 2010 to complete subjective sleep fatigue logs. Analysis of the sleep fatigue logs revealed a relationship between sleep quality and performance (golf score). Subsequent relationships were also found between subjective fatigue and sleep quality, and subjective fatigue and performance. These results could have important implications for athletes and others who require consistently skilled performance in the course of their duties; particularly for those individuals that are subjected to extreme travel schedules, extended work shifts or extreme work environments
