Multivariate modeling and analysis of regional ocean freight rates
2018
Abstract In this paper, we propose a new multivariate model for the dynamics of regional ocean freight rates. We show that a cointegrated system of regional spot freight rates can be decomposed into a common non-stationary market factor and stationary regional deviations. The resulting integrated CAR process is new to the literature. By interpreting the common market factor as the global arithmetic average of the regional rates, both the market factor and the regional deviations are observable which simplifies the calibration of the model. Moreover, forward contracts on the market factor can be traded in the Forward Freight Agreement (FFA) market. We calibrate the model to historical spot r…
Assessment of proneness to distraction: English adaptation and validation of the Attention-Related Driving Errors Scale (ARDES) and cross-cultural eq…
2016
Abstract Prior research developed the Attention-Related Driving Errors Scale (ARDES), a 19-item questionnaire aimed at evaluating the drivers’ predisposition to attentional error, and also provided validity evidence of ARDES measures across two countries: Argentina and Spain. In the current work we adapt the Spanish version of the ARDES to the English language and the culture, traffic regulations and driving habits of the UK, and then provide new evidence of the cross-cultural equivalence of the scale. First, an improved forward and backward translation design was used to translate the Spanish ARDES into English. A committee-approach review process was also performed during the translation …
The impact of scrappage programmes on the demand for new vehicles: Evidence from Spain
2018
Abstract We evaluate the impact of the Spanish car scrappage programme introduced in May 2009 on short-run car purchases. The scrappage programme was simultaneously discussed and implemented and was therefore exogenous to the consumers. We analyse the effect of this programme on household new car purchase decision and household expenditures. The results show that the scrappage programme increased the probability of buying a new car but decreased the mean expenditure devoted to the purchase of this new vehicle. We also evaluate the effect of financial aid on household welfare. Our best estimate of the welfare gain related to the scrappage programme is very similar to the aid of €1000 offered…
Estimating the Demand for New Destinations for a Regional Airport Based on Its Catchment Area
2020
Abstract Estimating accurately demand both at market and company level for specific goods and services can be considered a necessity for every organization. Traditional demand estimation methods may not be relevant for estimating the demand for new destinations to be introduced by a regional airport. The present paper proposes to fill this gap and to develop the demand estimation literature by presenting a novel demand estimation method. Two research objectives are developed in this regard: (1) determining the catchment area of Sibiu International Airport (a regional airport in Romania) for destinations operated by competitor airports and not by Sibiu International Airport and (2) estimatin…
Competition and cooperation for intermodal container transhipment: A network optimization approach
2018
Abstract This study presents an analysis of cross-border competition and cooperation between ports in Bangladesh and India. Nepal and Bhutan are countries without access to seaports — two landlocked countries in South Asia, depending solely on the Indian port of Kolkata for their international seaborne trade. Alternatives do exist in the Bangladeshi ports of Chittagong and Mongla but these are not exploited, in spite of trade agreements that allow access to a third country's port, and/or crossing the land of a third, intermediate, country. We formulate a mixed integer linear programming optimization model to find the optimum economic benefit of port users (serving Bhutan, Nepal and Northeas…
The impact of an urban toll ring on housing prices
2020
Abstract Building on standard urban economics theory we set up a stylized model within which we demonstrate that the imposition of a toll ring leads to higher housing prices within the ring, and lower outside the ring. We examine this prediction empirically by using transaction data for 15,306 dwellings in the Norwegian town of Kristiansand, where since 1992 there has been a toll ring. We find that the toll ring implies 6.9 per cent higher housing prices within the toll ring than outside it. The relationship between toll fees and housing prices seems to be stable over time. The impact of the toll ring on the prices of detached houses, apartments, row houses and twin houses is strikingly dif…
A stochastic dynamical social model involving a human happiness index
2018
[EN] This paper presents a new human happiness index built through five dimensions: development, freedom, solidarity, justice and peace. These five dimensions are evaluated through quantitative variables obtained from the Human Development Reports, World Data Bank and Eurostat. The new happiness index has been built following the guidelines set by the Human Development Reports of the UN for the construction of quality indices, and it has been compared on a set of 13 EU countries with the Overall Life Satisfaction Index, which is used by the UN. Moreover, the new index has been included in a dynamic mathematical model through the demographic rates to study the evolution of the population. Th…
The content and potential of the right to social assistance in light of Article 13 of the European Social Charter
2020
This article explores the current development of the right to social assistance as well as its potential for improving income support policies. Focusing on Article 13 of the European Social Charter (ESC), it aims to shed light on the content of such provision by identifying a list of comprehensive defining standards from the monitoring activity conducted by the European Committee of Social Rights (ECSR). Secondly, it asks whether the right can effectively enhance access to social assistance in practice by studying the implementation of the right in two national cases, the UK and Spain. The article concludes that Article 13 ESC imposes clear obligations on States Parties regarding aspects o…
Internal coordination of social security in Italy
2019
This contribution deals with the internal coordination of health care, long-term social care and social assistance schemes – covered by EU regulation no. 883/2004 – in Italy after the constitutional reform enacted in 2001, which significantly decentralised legislative and administrative machinery by strengthening the prerogatives of the Regions, especially in terms of organisation and funding of the services. This article seeks to demonstrate that, although the decentralisation of health care and long-term social care has been accompanied by mechanisms of internal coordination among the Regions (particularly in the field of inter-regional mobility), regional social assistance schemes provi…
Another "French paradox": explaining why interest rates to microenterprises dit not increase with the change in French usury legislation
2015
Conventional wisdom indicates that the growth of credit may not materialize if credit rates remain capped by usury laws, as had long been the case in France. France therefore abolished usury ceilings on loans to microenterprise in an effort to increase financing for microentrepreneurs. This should have led to an increase in interest rates and increase in microcredit. However, we do not find any increase in interest rates and this is therefore a paradox. The paper provides a brief literature review and the salient features of the legislative changes in France. It follows this up with a presentation of interest rate movements. The discussion of possible explanations of the paradox includes cl…
