Publicación Rethinking the Income Inequality and Financial Development Nexus. A Study of Nine OECD Countries(MDPI, 2020-07-06) Rodríguez, José Miguel; Cuesta González, Marta María de la; Ruza Paz-Curbera, CristinaFinancial crises have devastating effects in terms of income inequality. The recent financial crisis has provoked that inequality within advanced countries has returned to the prevailing levels of a century ago. In this article we look at the relationship between financial development and income inequality from a comprehensive perspective. Our hypotheses state that not only financial depth through credit expansion or capital markets activity matter in terms of income inequality, but also the financial system resilience. We look at a group of OCDE developed countries during the period 2000-2015 and the results confirm that in terms of credit provision there is a point of until which income inequality improves, but beyond this threshold further financial deepening will lead to a reverse effect, in line with the "Too much finance hypothesis". The role of capital markets exerts a widening income inequality effect while financial system resilience helps in alleviating existing income inequality. We recommend regulators and policymakers to pay more attention to financial depth variables, the behaviour of financial intermediaries and the environment in which they operate.Publicación The non-linear impact of financial development on environmental quality and sustainability: evidence from G7 countries(MDPI, 2022-07) Caro Carretero, Raquel; Ruza Paz-Curbera, CristinaThis paper analyses the impact of financial development on the environmental quality and sustainability for the group of G7 countries over the period 1990–2019 based on static panel data-fixed effect models. The objective is to explore if there exists a non-linear relationship between the whole financial system development and a wide array of measures of environmental sustainability and degradation, namely adjusted net savings, greenhouse gas, CO2, methane, nitrous oxide emissions and ecological footprint. We define a new Financial Environmental Kuznets Curve (FEKC) by introducing the square term of financial development on the environment-finance relationship. Empirical results prove the existence of non-linear relationships between the composite index of financial development and environmental degradation for the group of advanced economies. In the case of methane, we validate the presence of an inverted-U shape association in line with the FEKC hypothesis, while for greenhouse gas and CO2 the link follows a U-shaped pattern. The impact of financial development on environmental sustainability is monotonically positive and statistically significant while the ecological footprint is not statistically linked with the level of financial development within G7 countries. Economic growth, human capital, population density and primary energy consumption appear as significant drivers of environmental quality and sustainability.Publicación The relationship between vulnerable financial consumers and banking institutions. A qualitative study in Spain(Elsevier, 2021-01-05) Fernández Olit, Beatriz; Cuesta González, Marta María de la; Paredes Gázquez, Juan Diego; Ruza Paz-Curbera, CristinaThe financial exclusion phenomenon has been approached from different perspectives. After reviewing the recent literature, we adopt a financial ecology approach and propose a comprehensive framework to analyse the different types of difficulties (access, use and perception) that vulnerable financial consumers face in relationships with banking institutions as well as their underlying causes. We consider financial inclusion as the sustainable provision of financial services and products and an adjustment to individual needs. We examine a special group of urban vulnerable consumers: underbanked people facing poverty and social exclusion. Data were obtained from focus groups and were coded and analysed using qualitative data analysis software. The results show that use difficulties predominate, followed by perception difficulties. Bank pressure and lack of financial training stood out among the main causes of these financial difficulties. We conclude that poorer neighbourhoods constitute a distinctive financial ecology produced by the ‘discrimination’ of a significant number of their inhabitants in the use of mainstream financial services. The study provides evidence of the socio-spatial nature of the exclusion process and calls for further research on the role of policy responses to restrict abusive practices.Publicación Unveiling the non-linear dynamics: quantile regression of financial development's impact on environmental degradation in BRICS and G7 nations(Springer, 2025-01-29) Ganda, Fortune; Ruza Paz-Curbera, Cristina; https://orcid.org/0000-0003-2174-7384The growing environmental risks have become a major concern these days. This study examines within the EKC framework the long-term impact of income and financial development on environmental degradation assuming that this relationship is non permanent. The non-linear effect of financial development on CO2 and GHGs has not been analyzed in the literature, and this study applies panel quantile regressions to the group of BRICS and G7 over 1990–2019. It also separately assesses the long term impact of financial institutions versus financial markets development. The results confirm that financial development helps reducing CO2 and GHGs emissions after a threshold within the group of lower emitters (inverted U-shaped pattern). Going further, financial institutions have a positive effect on the environment, but financial markets exert a negative impact. The EKC hypothesis does not find support in this study and there is a U-shaped link between growth and polluting emissions. These empirical findings contribute to a better understanding of the pollution-income-financial development nexus in the long-term and provide insight to the policymakers, regulatory bodies, financial intermediaries and investors aligned with sustainable development goals.Publicación Impacto económico y social de sentencias por asuntos relacionados con el ámbito financiero(Thomson Reuters Aranzadi, 2020) Ruza Paz-Curbera, CristinaPublicación The relationship of vulnerable financial consumers with banking institutions.
