Assessing the impacts of social norms on low-carbon mobility options
(Elsevier, 2022-02-03) Mundaca, Luis; Román Collado, Rocío; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
Policymakers and scientists are paying increasing attention to how social norms can promote pro-environmental behaviour and sustainable energy use. We contribute to this field by experimenting with and assessing the impacts of social norms on low-carbon mobility options. Taking Sweden as a case study, we develop two complementary randomised controlled experiments to: 1) analyse the role of social norms in promoting the adoption of car sharing services (CSS) via descriptive and injunctive norms (N = 720); and 2) investigate potential crowd out effects when injunctive norms are used to promote a low-carbon transport hierarchy (N = 730). First-order effects show that social norms have a positive but marginal impact on the willingness to adopt CSS, and only injunctive norms have the potential to steer behaviour in the desired direction. Results also suggest that concerns about potential substitution effects between low-carbon transport options and CSS are not valid. With due limitations, our findings have various implications for policymaking, notably that for social norms to be effective, other policy instruments are critically needed. Of particular importance are the environmental effectiveness of CSS and complementarities between public transport and active mobility (i.e. walking and cycling).
The role of energy efficiency in assessing the progress towards the EU energy efficiency targets of 2020: evidence from the European productive sectors
(Elsevier, 2021-07-01) Román Collado, Rocío; Economidou, Marina; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
Energy efficiency is considered to be one of the most reliable ways of addressing some of the most pressing global challenges, such as energy independence and the fight against the negative effects of climate change. It is widely recognised that the EU path towards decarbonisation has to be accompanied by energy efficiency improvements. Focusing on the EU28 from the year 2000 onwards, this analysis aims at identifying the main driving factors behind the energy consumption changes at the global and sectoral level. Concretely, our focus on the productive sectors (responsible for 41% of total consumption) is due to the importance that these sectors have in reaching the overall EU targets. The novelty of this paper is that index decomposition analysis (concretely, LMDI-I) is applied considering: i) the alternative effects to the traditional ones; ii) different degrees of disaggregation and iii) new methodological approaches according to the most recent research literature on this topic. The results suggest that there have been important energy efficiency gains during the period studied. Without these gains the progress achieved towards the EU energy efficiency targets would have been difficult to attain. Despite this, the physical-based analysis shows that the energy efficiency gains are of a lower magnitude compared to the monetary-based analysis. The results provide some energy policy recommendations related to the effectiveness of past energy efficiency measures and shed light on key sectors for which there is still room for improvement.
The impacts of environmental collaboration on the environmental performance of agri-food supply chains: a mediation-moderation analysis of external pressures
(Taylor & Francis, 2024-01-30) Werneck Barbosa, Marcelo; Cansino Muñoz-Repiso, José Manuel; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
Although researchers have investigated the relationship between inter-organisational collaboration and ﬁrm performance, there is scatteredevidence on the relationship between environmental collaboration andenvironmental performance in agri-food supply chains. This studyassesses the eﬀects of environmental collaboration on ﬁve dimensions ofenvironmental performance (greenhouse gas emissions management,energy management, food waste management, food safety management,and water footprint management) in agri-food supply chains, particularlywhen mediated and moderated by customer and regulatory pressures.This study used a survey of Chilean agri-food companies. The data wereanalyzed using partial least squares structural equation modelling. Wefound that environmental collaboration positively inﬂuences all ﬁvedimensions of environmental performance and that customer andregulatory pressures mediate this relationship. The dimension mostaﬀected by environmental collaboration was water footprintmanagement. Finally, we provide recommendations for improving theenvironmental performance of companies in agri-food supply chainsthrough collaboration.
Key effects contributing to changes in energy imports in the EU-27 between 2000 and 2020: A decomposition analysis based on the Sankey diagram
(Elsevier, 2024-11-02) Román Collado, Rocío; Casado Ruiz, Virginia; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
The aim of this paper is to analyse the key effects contributing to changes in energy imports in the European Union (EU-27) in the period 2000–2020. Using the Logarithmic Mean Divisia Index (LMDI), the analysis examines the effect of changes in six factors—energy structure, energy dependence, energy transformation efficiency, energy yield after transformation, energy efficiency and activity—on imports of oil, natural gas and other sources of energy. The results of the analysis reveal that the decarbonisation process has fostered the abandonment of the most polluting fossil fuel sources; however, there has been an increase in energy dependence on less polluting sources that are not produced domestically. In contrast, there has been an opportunity for change through improved energy efficiency, which has made it possible to reduce energy requirements per unit produced. In short, in order to achieve a sustainable and secure energy future, it is crucial to implement policies and actions that promote both the diversification of the energy mix—particularly renewable energies—and efficiency in consumption. Doing so will enable countries to move towards true decarbonisation and minimise vulnerability in their energy supply.
Cruising challenging seas: 'how was your experience?'
(Routledge, 2024-08-07) Castillo Manzano, José I.; Castro Nuño, Mercedes; Pozo Barajas, Rafael del; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política; Universidad de Sevilla. Departamento de Economía Financiera y Dirección de Operaciones
After a text-mining process analyzing over 204,710 semantic cruise reviews on social media for the period 2000-2024, this paper examines how cruisers’ satisfaction and emotions evolved pre-, during-, and post-COVID. Applying a novel methodological mix of sentiment analysis and econometric models, the results show that cruisers’ global satisfaction has increased, possibly due to a loyalty bias among cruise enthusiasts. The experience improved regarding specific issues such as ship size, premium services, timely post-cruise reviews, particular destinations, and cruise crew.
Implementing the Circular Economy in the European Union and Spain: Links to the Low-Carbon Transition
(MDPI, 2024-10-22) Pablo-Romero Gil-Delgado, María del Populo; Sánchez-Braza, Antonio; Torreblanca, Cristóbal; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
This paper reviews and analyzes the process of the implementation of the circular economy in the European Union (EU) and Spain, and its links to the low-carbon transition. The EU implementation of the circular economy went through several stages. Since the adoption of the first action plan in 1993, the links between the circular economy and carbon transition goals have become intertwined. Recently, the EU approved the framework of new monitoring measures and indicators for the circular economy. The adopted actions have involved the adaptation of European legislation at the national level. Spain has participated in this process since 2017, when the Circular Economy Pact was signed. The subsequent approval of the Spanish Strategy for a Circular Economy in 2020 was developed, considering a close relationship between decarbonization and the circular economy. Lately, the circular economy implementation has been strengthened with the strategic project for economic recovery and transformation, linked to the recovery of COVID-19, and the roadmap for the sustainable management of mineral raw materials, with both documents including actions directly related to transforming the energy system. Data show that Spain has made significant improvements in the circular economy transition. However, Spain’s vulnerability to externalities is greater than that of the EU as a whole.
Examining the use of instructional video clips for teaching macroeconomics
(Pergamon-Elsevier Science, 2020) Expósito García, Alfonso; Sánchez-Rivas García, Javier; Gómez-Calero Valdés, M. Palma; Pablo-Romero Gil-Delgado, María del Populo; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
Information and communication technologies (ICTs) have been integrated in teaching activities to develop new learning environments. Within ICTs, the use of multimedia, such as instructional videos, has attracted significant academic attention. Nevertheless, the use of these technologies in teaching economics has generally lagged behind other disciplines. This paper adds empirical evidence to show the effectiveness of the use of instructional videos in the field of economics. Firstly, videos illustrating dynamic graphical representations of macroeconomic processes have been developed and used in the class of one student group at the University of Seville (Spain), as complementary teaching materials in the macroeconomics curriculum. Secondly, the effectiveness of these videos has been tested by carrying out an inferential analysis on experimental and control groups. In addition, probit and multinomial probabilistic regressions have been estimated in order to assess the impact of these materials on the probability of achieving higher test scores. The findings confirm the superiority of using instructional video-clips to achieve higher test scores.
Relationship between economic growth and residential energy use in transition economies
(Taylor & Francis, 2019) Pablo-Romero Gil-Delgado, María del Populo; Sánchez Braza, Antonio; Galyan, Anna; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
This paper analyses the relationship between economic growth and residential energy consumption in 12 transition economies during the 1995-2013 period, by testing the EKC hypothesis. Urbanisation, population density, transition level and structural change have been included in the estimate process as control variables. The estimate results are compatible with the EKC hypothesis. However, the turning point has not been reached, although Russia is close to it. The results also show that, for countries with low income levels, the economic growth has been reducing the residential energy consumption, which may be related to efficiency gains. Nevertheless, for countries with higher income values, the economic growth has increased the residential energy consumption. Therefore, it may be adequate to establish energy efficiency measures in households and buildings, and promote the use of renewable energy, in order to reduce environmental problems. The results also show that the elasticity values are not constant over time and countries. These differences make it recommendable to adapt the energy policy to each country. The results also show that the urbanisation, higher transition level towards a market economy, and the structural change of the economy towards to one that is more tertiary based, have positive effects in reducing residential energy use.
Industry level production functions and energy use in 12 EU countries
(2019) Pablo-Romero Gil-Delgado, María del Populo; Sánchez-Braza, Antonio; Expósito García, Alfonso; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
Energy use reduction in the industrial sector is especially relevant, as the sector consumes about 54% of the world’s total delivered energy. In the EU context, industry sectors have significantly reduced their energy consumption in the last decade, nevertheless significant disparities being across industry branches. Despite these differences, to our knowledge, there are no previous studies which analyses the effect of energy use in the production by comparing this effect in several industrial branches nor related to the EU countries, from a growth perspective. The aim of this study is to analyze the effect of energy use in the branches of industry within a growth framework in 12 European countries. Industry-level translog production functions are estimated by using panel data relating to 12 European countries and the 2000-2014 period. In addition, two sub-periods are studied to evaluate if industrial energy efficiency has been improving through time, specifically from 2007. Findings confirm the existence of different behavior patterns with respect to energy use in the considered sectors and from one period to another. As a result, policy measures should be sector-specific, since no general production-energy use patterns can be obtained.
Measures to promote renewable energies for electricity generation in Latin American countries
(Elsevier, 2019) Washburn, Christian; Pablo-Romero Gil-Delgado, María del Populo; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
This study analyses the measures used to promote renewable energy for electricity generation in the 18 Latin American countries that signed the Paris Agreement, in an electricity demand growth context. The Latin American countries have had a remarkable growth in the use of renewable energy for electricity generation. Biomass, wind and solar energy have experienced strong growth, however, their participation in the energy mix remains small. All the studied countries have established renewable energy targets, 16 having adopted at least one promotion measure. The most used measures are tax incentives, mainly through exemptions in income tax, value added or sales tax and on tariffs. Also, most countries are using auction systems, which are replacing the Feed-In Tariff system. The net metering system adoption is also growing in the region. The results of the study show a positive relationship between the most active countries in renewable energy promotion and the performance achieved in the studied years. Therefore active policies are considered necessary for the future development of renewable energies.
Income, extreme temperature, and residential electricity consumption in the Spanish provinces
(World Scientific Publishing, 2024) Pablo-Romero Gil-Delgado, María del Populo; Sánchez Braza, Antonio; Izquierdo, Claudia Priscila; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
The effect of income and extreme temperatures on the residential electricity consumption in Spain is analyzed. An electricity demand function is estimated by means of ordinary least squares- Driscoll and Kraay, feasible generalized least squares, and quantiles panel data techniques, for the total of the sample, and by coastal climatic zones. The results support the energy-environmental Kuznets curve hypothesis for Spain, the continental and Mediterranean zones. An N form is found for the Atlantic zone. The results also reflect that increases in temperature above 22ºC, and decreases below 15ºC, increase electricity consumption, this increase being progressive as temperatures vary. Thus, extreme temperature generates electricity consumption growth. The Mediterranean zone is most sensitive to these temperature changes. The results also show that electricity consumption is more sensitive to cold than to heat. The results suggest an inefficient use of heating and cooling appliances in the areas with the highest electricity consumption.
Key driving forces of energy consumption in a higher education institution using the LMDI approach: The case of the Universidad Autónoma de Chile
(Elsevier, 2024-10) Laporte, Juan P.; Román Collado, Rocío; Cansino Muñoz-Repiso, José Manuel; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
Energy consumption in universities is a crucial issue as they aim to balance growing operational demands with environmental sustainability. This study employs the Logarithmic Mean Divisia Index method to assess energy consumption variations at Universidad Autónoma de Chile from 2017 to 2022, demonstrating the method's efficacy and simplicity in decomposing energy use into its determinants. The analysis reveals a 19% increase in energy consumption, primarily fueled by heightened energy intensity from increased research activities and rising enrollment. However, weather conditions and infrastructural efficiencies have mitigated this increase. Notably, the 2020 remote learning period saw a 45% decrease in energy consumption, largely due to reduced energy intensity. This study validates the LMDI method for individual institutions and provides a clear, interpretable framework for understanding energy variations. It highlights the impact of the Chilean accreditation system, which indirectly induces energy consumption expansions in universities by requiring enlargements in gross floor area. The findings also emphasize the significant effect of weather on energy usage in extreme climates. Recommendations for Universidad Autónoma de Chile include implementing behavioral change programs, enhancing climate control, and lighting systems, conducting energy audits, pursuing building retrofitting, and considering a partial shift to remote learning to further reduce energy consumption.
Green Innovation and Energy Efficiency: Moderating Effect of Institutional Quality Based on the Threshold Model
(Springer, 2024) Chen, Chaoyi; Pinar, Mehmet; Román Collado, Rocío; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
Recent studies demonstrated that green innovation and environment-related technologies reduce energy intensity and improve energy efficiency, contributing to the reduction of carbon emissions. However, the existing studies employ linear estimation methods to examine the relationship between green innovation and energy intensity and do not consider the indirect implications of institutional quality for the effect of green technology on energy intensity. Institutional quality is found to be an essential driver of innovation, and countries may need to achieve at least a minimum level of institutional quality to promote green innovation and improve their energy intensity. To test this hypothesis, this paper examines the relationship between energy intensity and green innovation using a panel dataset from 72 countries between 1996 and 2017 and a panel threshold model when institutional quality is considered a threshold variable. The findings highlight that green innovation reduces the energy intensity if and only if countries surpass a certain threshold of institutional quality. Therefore, countries need to improve their institutional quality to promote green innovation and benefit from green technologies in improving their energy intensity.
Asymmetric effects of EU cohesion policy on EU regional growth: The role of macroeconomic uncertainty
(Elsevier, 2024) Pinar, Mehmet; Karahasan, Burhan Can; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
Cohesion policy and the EU funds have been key elements for territorial integration in Europe. Evidence shows that EU funds support the growth performance of regions. However, less has been discussed about the potential impact of macroeconomic uncertainty on the effectiveness of EU funds. Our analyses confirm that EU funds are important in understanding regional economic growth differences. However, the extent of macroeconomic uncertainty decreases the effectiveness of the EU funds. Our results are robust in including local controls, non-linearity of the EU funds’ effect, different EU fund categories, and regional heterogeneity in the EU.
Artificial Intelligence and sustainable tourism planning: A hetero-intelligence methodology proposal
(Universidade do Algarve, 2024) Buitrago Esquinas, Eva María; Yñíguez Ovando, Rocío; Puig Cabrera, Miguel; Custódio Santos, Margarida; Santos, José Antonio C.; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política; Universidad de Sevilla. Departamento de Economía Aplicada III
This study explores the growing significance of Large Language Models (LLMs) in tourism, for their current and potential applications. It aims to achieve two primary objectives: first, to develop a novel hetero-intelligence framework merging human and artificial intelligence (AI) to address contemporary sustainability challenges in tourism; second, to validate this framework by applying it to sustainable tourism planning, assessing LLMs' capabilities and limitations. The research employs a hetero-intelligence performance test, contrasting human intelligence and AI contributions in sustainable tourism planning with overtourism as a proxy challenge. Results showed that hetero-intelligence could effectively address sustainability issues in tourism, provided human and AI strengths and weaknesses are understood. LLMs proved useful in diagnosing and proposing solutions for sustainability-related issues. However, a rigorous methodological framework is essential to ensure unbiased outcomes. The research offers practical guidelines for applying this approach and significantly contributes to epistemological and empirical dimensions, providing valuable insights for researchers and tourism planners. The study calls for more empirical research to validate the methodology and explore ethical and legal dimensions, extending hetero-intelligence applications to broader sustainability challenges in tourism.
Social tipping and climate change: The moderating role of social capital in bridging the gap between awareness and action
(John Wiley & Sons, 2024) Kaçani, Krisdela; Kokthi, Elena; López-Bonilla, Luis Miguel; González-Limón, Myriam; Universidad de Sevilla.

Bridging the gap between awareness and action on environmental issues such as climate change often requires understanding the moderating roles of individual trust, institutional trust and civic engagement. This paper explores how social capital, through generalaised trust, trust in institutions and civic engagement, can either strengthen or weaken the agency on climate change on environmental behaviour. Linking climate change awareness to environmental behaviour through the mediation of perceived changes in quality of life is the chosen approach to explore the role of social capital. The results suggest that low levels of trust, whether interpersonal or institutional, reduce an individual's sense of agency by firstly reducing the impact of climate change awareness on quality of life, changing perceptions and consequently reducing environmental behaviour. Greater trust in institutions produces a stronger effect of climate change awareness on willingness to pay. On the other hand, civic engagement shows a significant effect when taxes are considered. The study suggests that the impact of social capital on environmental payments varies according to the type of payment (voluntary vs. mandatory). The mapping of the role of social capital in reducing the agency of climate change awareness in quality-of-life changes should be further explored, as the latter has proven to be a promising way to address climate change in developed and developing countries.
La cobertura hospitalaria de la tuberculosis en la España franquista, 1936-1977
(Centre d'Estudis Històrics Internacionals de la Universitat de Barcelona, 2023) García Cruz, Elena; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política
La tuberculosis es una de las enfermedades con mayores tasas de mortalidad en España en gran parte del siglo xx y que más ha perdurado hasta conseguir reducir su incidencia. Durante el primer franquismo fue la primera causa de mortalidad de la población española. Ni siquiera los esfuerzos por aumentar el número de sanatorios del Patronato Nacional Antituberculoso consiguió que la mortalidad por esta causa disminuyese. El cambio de tendencia vino de la mano de otros factores, como la introducción en el país de la estreptomicina, un antibiótico muy costoso de conseguir durante los primeros años de la dictadura o la introducción de campañas de higiene y vacunación. El último esfuerzo del franquismo para frenar esta enfermedad fue la creación del Plan Nacional de Erradicación de la Tuberculosis, cuyos resultados son cuestionables. El objetivo de este trabajo es incidir en la cuantificación y evolución de los sanatorios del Plan Nacional, dibujar su papel en la estrategia de lucha antituberculosa en este periodo y analizar su decadencia y cambio de funcionalidad de muchos de ellos en los últimos años del franquismo.
Productive electricity and non-electricity consumption effects on economic growth: A Latin America analysis
(Pergamon-Elsevier Science Ltd, 2024) Pablo-Romero Gil-Delgado, María del Populo; Pozo Barajas, Rafael del; Washburn, Christian; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política; Universidad de Sevilla. Departamento de Economía Financiera y Dirección de Operaciones
Electrification is a key pillar in energy transformation to reduce emissions. However, it may also have consequences on production. This study analyzes the effect of using electricity and non-electricity energy sources on production growth. An extended neoclassical production function, with the two uses of energy (electricity and non-electricity), is estimated for 17 Latin American countries from 1990 to 2019 and, for subsamples, based on the level of production per persons employed. The study is performed applying the cross-sectionally augmented, autoregressive distributed lag modeling approach and a non-parametric time-varying coefficients model. The parametric results indicate that the effect of both sources of energy on production are positive and significant. However, the production elasticity with respect to non-electricity consumption is higher than that with respect to electricity consumption. Only in countries with the lowest production levels could electrification be neutral. The non-parametric results show that the effect of non-electricity consumption is decreasing slightly over the period, while the effect of electricity use is increasing slightly, with a tendency towards stabilization at the end of the period. Nevertheless, these changes have been small.
The effect of bubbles on production: The state of the literature
(Wiley, 2024) Fernández González, Cristhian; Hierro Recio, Luis Ángel; Domínguez Torres, Helena; Universidad de Sevilla. Departamento de Análisis Económico y Economía Política; Universidad de Sevilla. Departamento de Economía e Historia Económica; Universidad de Sevilla. Departamento de Economía Aplicada I
In this paper, a comprehensive review is carried out on the strand of the literature related to the effects of bubbles on production, which includes the scarce empirical literature. The content is structured according to the bubble phase, since a major part of the literature considers that during the boom, there can be a crowding-in effect that can even offset the crowdingout effect derived from the bursting of the bubble. This possibility is due to the influence of two opposing mechanisms: a substitution effect derived from the possible diversion of resources previously allocated to productive investments, and an income effect derived from the fact that investors have more resources obtained from the sale of the bubble assets and from the role of these assets as collateral in loan operations. Studies also show the negative effect derived from the involvement of banks in bubbles. In this paper, both the results of the research and the main methodological framework are reviewed, thereby identifying as a gap in the literature to be considered for future research: the scarcity of empirical research, of studies that include demand factors, of papers that address bubbles in nonfinancial and nonhousing markets, and in undeveloped and emerging countries
