Labour Market Uncertainty and Career Perspectives: Competence in Entrepreneurship Courses

2016

Nowadays entrepreneurship is high on the agenda of many countries, and the number of entrepreneurship education initiatives is growing fast. Since the beginning of the third millennium, European Union institutions (European Commission 2003, 2009, 2010, 2013), OECD (2010) and national governments across the European Union have become increasingly involved in entrepreneurship education. The various schemes and initiatives address primarily two broad objectives, on the one hand, supporting new business start-ups and, on the other hand, developing an entrepreneurial mindset in society (and among the young in particular). For example, an international survey conducted by the European Commission …

Dealing with preference uncertainty in contingent willingness to pay for a nature protection program: A new approach

2013

In this paper, we propose an alternative preference uncertainty measurement approach where respondents have the option to indicate their willingness to pay (WTP) for a nature protection program either as exact values or intervals from a payment card, depending on whether they are uncertain about their valuation. On the basis of their responses, we then estimate their degree of uncertainty. New within this study is that the respondent's degree of uncertainty is "revealed", while it is "stated" in those using existing measurement methods. Three statistical models are used to explore the sources of respondent uncertainty. We also present a simple way of calculating the uncertainty adjusted mea…

Performance assessment of water companies: A metafrontier approach accounting for quality of service and group heterogeneities

2021

Abstract The assessment of water companies’ efficiency, productivity and quality of service is part of the process to set water tariffs and therefore, is relevant for regulators and customers. However, the water industry involves several heterogeneous water companies. Following a pioneering approach, this study estimates productivity change and its drivers considering the non-homogeneous nature of the water companies and incorporating quality of service variables as undesirable outputs. In doing so, the metafrontier Malmquist Luenberger productivity index was estimated for a sample of English and Welsh water and sewerage companies (WaSCs) and water only companies (WoCs) over the years 2001–…

Exploring the relationship between Information and Communication Technologies (ICT) and academic performance: A multilevel analysis for Spain

2021

Abstract With the world becoming increasingly digitalized, determining the relationship between the use of Information and Communication Technologies (ICT) and educational outcomes takes on special relevance for guiding educational policy decisions in a reasoned way. The objective of this research is to explore the relationship between different types of ICT use at school and at home, students' attitudes towards ICT, and academic performance, as well as to see if these associations differ according to the level of performance of the students. For this purpose, we apply multilevel regression models and quantile regression models with data from the Programme for International Student assessme…

Macro-uncertainty and financial stress spillovers in the Eurozone

2020

Abstract This paper studies macro-uncertainty and financial distress spillovers within the Eurozone. We propose a novel methodology to derive the indices of spillovers, by using a Global Vector autoregressive model fitted to data sampled at mixed-frequencies. We find that macro-uncertainty and financial stress are relatively disconnected in the Eurozone. We also show that connectedness between core and periphery Eurozone countries mainly operates through financial stress and it decreases since the outbreak of the Eurozone sovereign debt crisis (with an increasing role played by peripheral countries). As a result, investors and policymakers should monitor separately macro-uncertainty and fin…

COVID‐19 and tourism: What can we learn from the past?

2020

Abstract The impact of the COVID‐19 crisis on tourism flows is without precedent in terms of speed and severity. In this paper, we try to infer a possible future scenario for the tourism sector, evaluating the medium‐term effects of past pandemics on tourist arrivals. We find that pandemics lead to a persistent decline in tourist arrivals, with the effects being larger in developing and emerging countries. Interestingly, the effects are heterogeneous across countries and episodes, and depend on several economic conditions such as the overall health system performance, the severity of the shock, and the uncertainty induced by the pandemic event.

A multiple criteria decision model for analyzing and choosing among different development patterns for the Helsinki cargo harbor

1999

Abstract This paper describes a real application of a multicriteria approach to choosing among different options for developing the Helsinki harbor. In addition to the environmental impact assessment procedure, an analysis of the alternatives using the SMAA-method (Stochastic Multiobjective Acceptability Analysis) is carried out. The method applied here has been developed for situations in which the use of decision-makers’ preference information is not possible. Instead, the problem is described by typical weight vectors leading to each solution, taking into account the evident uncertainty embedded in the criteria values.

Development of a complex approach for evaluation of statistical data

Utilidad pública de las asociaciones. Revocación por la Administración y solución fundacional.

2019

La finalidad no lucrativa de las asociaciones puede encaminarse a la consecución de fines tanto de interés particular como de interés general. En este segundo caso, la búsqueda del bien común les hace merecedoras de una especial protección por parte de los poderes públicos que se concreta en su declaración legal como «asociaciones de utilidad pública». Sin embargo, tras la Ley Orgánica de Asociaciones, de 22 de marzo de 2002 (LODA), la administración se muestra renuente a otorgar la calificación de utilidad pública a aquellas asociaciones que, en aras a allegar recursos para el cumplimiento de sus fines, desarrollen una actividad económica. A resultas de dicho proceder administrativo estas …

Socio-economic inequality, interregional mobility and mortality among cancer patients: A mediation analysis approach

2022

This paper investigates the effect of socio-economic status on interregional mobility and mortality among cancer patients. The cohort under analysis comprises patients residing in Sicily (Italy), who were diagnosed with lung and colon cancer between 2010 and 2011. The data was collated from the hospital discharge records of the Sicilian Region and the Regional register of the causes of death, by considering all those patients for whom information relating to socio-economic status was available. First, graphical models were applied to highlight the multivariate structure of association among socio-economic status, interregional mobility and 3-year mortality. Secondly, mediation analysis quan…
