Household private saving and public pensions in Germany and the United States:¿Does the life-cycle hypothesis hold?

This paper details how ageing is affecting to private saving and public pensions. In this way, it analyses if Life-Cycle Hypothesis is carrying out for individuals about their saving behaviours and if Pension Public Systems can make them to vary. For this reason, it establishes a specifically household saving comparative for Germany and Unites States, studying also their ageing evolution and pay capacity of public pension retirement.life–cycle hypothesis, private saving, pension public system, ageing, Germany, United States

Analysis of concentration in the spanish electricity output after liberalisation

This paper is about the Spanish Electricity Market after liberalisation. The analysis focuses on finding if the market has become as a Perfect Competition regimen or on the other side, he still continues as a regimen in wich a high output supply concentration and high power market appears, not allowing free-market prices as a consequence. Regarding on it, CTC´s are especially important, being responsible of voluntary actions of increasing prices by Electricity Companies with high market power, just trying to maximise incomes illegally.Liberalization, electricity output, competition and market power, Industry Concentration Indexes, energy prices, Competence Transition Costs

Acoustic event characterization for service robot using convolutional networks

This paper presents and discusses the creation of a sound event classification model using deep learning. In the design of service robots, it is necessary to include routines that improve the response of both the robot and the human being throughout the interaction. These types of tasks are critical when the robot is taking care of children, the elderly, or people in vulnerable situations. Certain dangerous situations are difficult to identify and assess by an autonomous system, and yet, the life of the users may depend on these robots. Acoustic signals correspond to events that can be detected at a great distance, are usually present in risky situations, and can be continuously sensed without incurring privacy risks. For the creation of the model, a customized database is structured with seven categories that allow to categorize a problem, and eventually allow the robot to provide the necessary help. These audio signals are processed to produce graphical representations consistent with human acoustic identification. These images are then used to train three convolutional models identified as high-performing in this type of problem. The three models are evaluated with specific metrics to identify the best-performing model. Finally, the results of this evaluation are discussed and analyzed

Global economy dynamics? Panel data approach to spillover effects

Over the past year, there has been considerable debate about how the slowing of the United States and other major developed economies affects output growth across the world. The main purpose of this paper is to establish relevant conclusions on how the U.S., Euro Area and Japan gross domestic product growth affect international business cycle fluctuations, with the objective of identifying the main factors that influence spillovers into other countries. Using panel data regression, we conclude that output growth in the U.S. and Euro area are significant in explaining output growth across countries. Depending on the specifications, trade linkages play a significant role while financial linkages with respect to the three regions does not (except in one particular specification). There are signs of potential omitted variable bias in some regression indicating that some relevant variables have not been taken into account. There is also clear evidence of a structural change in the transmission mechanism of shocks after 1985 – since when shocks have become more country-specific.Output Growth, Trade and Financial Linkages, Structural Break, Cross- Section Panel Data.

Análisis de la concentración en la producción de energía eléctrica tras la liberalización en España del Sector Eléctrico

This paper is about the Spanish Electricity Market after liberalisation. The analysis focuses on finding if the market has become as a Perfect Competition regimen or on the other side, he still continues as a regimen in wich a high output supply concentration and high power market appears, not allowing free-market prices as a consequence.

La producción de energía eléctrica en España: Análisis económico de la actividad tras la liberalización del Sector Eléctrico

This paper is about the Spanish Electricity Market after liberalisation. The analysis focuses on finding if the market has become as a Perfect Competition regimen or on the other side, he still continues as a regimen in wich a high output supply concentration and high power market appears, not allowing free-market prices as a consequence. In this sense, conclusions are based on Cournot-perfect competition analysis for three different electricity demand scenarios. Finally, Competence transitions costs are also especially important as responsible of voluntary actions of increasing prices by Electricity Companies with high market power

Efectos del incremento del precio del petróleo en la economía española: Análisis de cointegración y de la política monetaria mediante reglas de Taylor

The main purpose of this paper is to show evidence about the negative impact of oil price shocks in the economy of Spain. Since oil demand is continuously increasing all around the world and OPEC countries use to act having certain power to raise them, it is necessary to study how these price levels affect to inflation rate and output growth. Oil prices, inflation and interest rates and Gross Domestic Product historical data are collected for contegration analysis. Forward-looking and Backward-looking Taylor Rules are also estimated to compare their trend with respect to official interest rates and finally conclude if the European Central Banks takes these rules patterns into account
