Third Session

The third BBS meeting is coming soon!

We are pleased to introduce Raquel Langarita, and her paper titled: Economic and environmental effects of European goals for the Spanish electricity system.

This paper addresses the economic and environmental effects of three scenarios of change for the electricity sector in Spain, for which the European Union has stated a target: (1) regarding the low trade with the rest of Europe, increasing the integration with the European network; (2) taking into account the environmental sustainability, increasing the use of renewable energy sources, while decreasing the use of brown energy sources; (3) increasing the competitiveness of the Spanish electricity sector. To this end, authors develop a computable general equilibrium model, with 72 productive sectors, eleven of which are energy sectors, where electricity is disaggregated into five production technologies and transmission, distribution, commercialization and related activities. The model is calibrated on a previously developed input-output table with this detailed disaggregation for Spain for 2013. Preliminary results suggest potential improvements in production and trade, and reductions in CO2 emissions in scenario 2 are also observed.

The session will be held at the School of Economics and Business, Sala de Reuniones de la Magna - Edificio Paraíso -, Zaragoza, next Wednesday 14th of November at 13h30.

First Special International BBS Session

We are pleased to inform you about the First Special International BBS Session.

Taking advantage of the opportunity that Professor Bert Steenge is at our School for a few days, we are grateful to organize an extraordinary meeting.

We thank Professor Bert Steenge for his availability and kindness for accepting the invitation to participate in a BBS seminar.

The title of the paper he is presenting is Taxes and subsidies in input-output modelling; Lloyd Metzler's problem revisited.

In this paper, their proposition is that the analysis of taxes and subsidies in input-output (IO) analysis lacks a good foundation. As proof, they refer to Lloyd Metzler who -long ago- asked them to visualize a policy that taxed a specific product (say alcohol or tobacco) and used the revenues to subsidize another product, say green (i.e. sustainably grown) bananas or soy beans. Now, can they be sure that the taxed commodity increases in price and that the subsidized one decreases in price? Metzler moved to IO to try to answer the question, but got stuck in a very peculiar case. Since then, as far as they know, no 'general' proof or theorem has been given or presented. The question is important, also in the wider context of the effectiveness of tax/subsidy policies, particularly in the context of, say, climate change. In this presentation, they discuss an approach that may take them a step further to a general theory.

The session will be held at the School of Economics and Business, Sala de Reuniones de la Magna - Edificio Paraíso -, Zaragoza, next Wednesday 7th of November at 13h30.

Great Second Seminar!

We are pleased to thank José Ignacio Giménez-Nadal for his wonderful presentation about the relationship between gasoline tax rates and time workers in the United States spend commuting. He talked about how higher gasoline tax rates reduce the proportion of commuting by private car and increase proportions of commuting by public and alternative (e.g., walking, cycling) transport. Really interesting concerns and very useful results.

We would also like to thank all the attendees for coming and for their valuable and helpful comments and suggestions after the presentation.


Looking forward to seeing you all in the next meeting!

Second Session

Next BBS session is going on!

We have the pleasure of introducing José Ignacio Gimenez-Nadal and José Alberto Molina, and their paper titled: Green commuting and gasoline taxes in the United States.

This paper analyzes how gasoline tax rates are related to the time workers in the United States spend commuting by private car, or public transport, or with other physical modes of transport, using the American Time Use Surveys for the years 2003 to 2015. Our identification strategy relies on both between-state differences and time variations in gasoline taxes. We find that higher gasoline tax rates are related with less time spent in commuting. Furthermore, higher gasoline taxes are related to a lower proportion of commuting by private car, and higher proportions of commuting by public transport and/or a physical mode of transport (e.g., walking, cycling).

The session will be held at the School of Economics and Business, Sala de Juntas - Edificio Lorenzo Normante -, Zaragoza, next Wednesday 31st of October at 13h30.


Presenter: José Ignacio Gimenez-Nadal

The first session of the BBS was already held!


We would like to express our gratitude to all the attendees, especially to the Dean of the School of Economics and Business for his support and kind words, and to our wonderful presenters: Cristina Ortiz and Luis Vicente.

They did the inaugural BBS session with a brilliant presentation on the performance of Euro government bond mutual funds before and after the Euro debt crisis. They talked about the value of active management and the contribution of bond selection and timing abilities, showing really interesting and helpful results.

Also, we want to thank all the comments and suggestions of attendees after the presentation, by understanding that it contributes to hold further valuable and useful sessions.


Hope to see you at the next BBS session!

First Session

As promised, the organizing committee of the BSS is preparing the schedule for this semester and we are pleased to announce the First Session.

We start the BBS sessions with a study recognised with the Best Paper Award of 10th PFN Conference sponsored by Banco de Portugal-Eurosistema.

We have the pleasure of introducing Cristina OrtizGloria Ramirez, and Luis Vicente, and their paper titled: Euro government bond funds before and after the Euro debt crisis: Evidence from security-level holdings.

This study is the first to evaluate the performance of Euro government bond mutual funds with characteristic-based benchmarks. This analysis is based on the security-level holdings of the most afflicted countries in the Euro debt crisis, i.e., Greece, Italy, Portugal, and Spain (GIPS). The contribution of bond selection and timing casts doubt on the value of active management. The results also show a further increase in the home bias detected in the years preceding the crisis, especially in the most relevant GIPS industries. This stronger bias results in worse bond selection abilities and assorted timing skills across the GIPS markets.

The session will be held at the School of Economics and Business, Salón de Actos - Edificio Paraiso - Zaragoza, next Wednesday 17th of October at 13h30.

Presenters: Cristina Ortiz and Luis Vicente
