Seminario 24/05 – Adelaida Lillo (Universidad de Alicante): Does reshoring generate employment? A study on services reshoring and its intra- and inter-sectoral components
The aim of this paper is to deepen the analysis of services reshoring in the Spanish services sector, both as a whole and for its constituent elements, examining both intra- and inter-sectoral components. Likewise, it analyzes the impact of this strategy on employment in the services sector, also differentiating between broad reshoring, intra-sectoral reshoring and…
Seminario 24/02 – Adrián Nerja (Universidad de Alicante): How does environmental awareness for HSR influence the necessity for short-haul flight bans?
This paper applies a model in which a local market served by high-speed rail (HSR) and an airline is connected with an international market serving two different airlines. Our aim is to assess the necessity for a ban on short-haul flights from an economic policy standpoint and to investigate the potential for market self-regulation to…
Seminario 24/04 – Volker Schoer (University of the Witwatersrand, South Africa): Discursive classroom interaction practices and student achievement in mathematics: Evidence using an International large-scale education dataset
Improving the mathematics performance of school children is an objective for many policy makers around the world. It is obvious that mathematics teachers may have a key role to play in this process; however, robust examination of the teacher characteristics and practices of teachers that help to raise pupil mathematics achievement is relatively sparse, particularly…
Seminario 24/03 – Lourdes Molera y María Semitiel (U. Murcia): The contribution of university economics teaching to sustainability
We study how university economics teaching addresses sustainability. The priority of the topic has been evidenced in publications calling for a critical analysis of university programmes (Bowles, Carlin, 2020; Ansari, Landin, 2023; Prillaman, 2023). We analyse how sustainability is addressed in introductory economics courses for the degrees in Economics, Business Administration, and Law at public…
Seminario 24/01 – Mariola Sánchez Romero (Universidad de Murcia): The Impacts of Airline Corporate Social Responsibility in the Air Transport Industry
This paper investigates the implications of airline corporate social responsibility (CSR) uptake in the air transport industry. Then, we extend the analysis considering the impact of parallel airline alliances on CSR of airlines. The results suggest that airports play a crucial role in shaping the CSR practices of airlines and that this impact should be…
Seminario 23/14 – Luis Guardiola (Universidad de Alicante): Distribution of surplus generated through cooperation in supply chains with multiple suppliers and retailers
Abstract The coordination of actions and the allocation of profit in supply chains under decentralized control play an important role in improving the profits of retailers and suppliers in the supply chain. We focus on supply chains under decentralized control in which noncompeting retailers can order from multiple suppliers to replenish their stocks. The goal…
Seminario 23/13 – Christian Blum (Artificial Intelligence Research Institute, IIIA-CSIC): Recent Developments in Hybrid Metaheuristics for Combinatorial Optimization
A lot of research has been dedicated to solving combinatorial optimization problems during past decades, both in the Operations Research field and in Artificial Intelligence. As a result, researchers and/or practitioners are able to choose between a wide range of both exact and approximate techniques when faced with an optimization problem of that type. Nevertheless,…
Seminario 23/12 – José Manuel Cordero (Universidad de Extremadura): La consideración del contexto al analizar cambios en la productividad con modelos no paramétricos
Las variables de contexto o ambientales suelen desempeñar un papel importante en la mayoría de los procesos productivos, condicionando en gran medida tanto la estimación de los niveles de eficiencia de las unidades evaluadas como posibles factores explicativos de las ineficiencias detectadas en la mayoría de los estudios empíricos. Sin embargo, cuando se analizan los…
Seminario 23/11 – Behzad Hezarkhani (Southampton Business School, University of Southampton): Global Agricultural Supply Chains under Tariff-Rate Quotas
The tariff rate quota (TRQ) is a common market access instrument in global agricultural trade that allows a predetermined quantity of a product to be imported at a lower tariff rate than the rate typically applied to that product. In this study, we examine the design and administration of TRQ systems from an operations management…
