Hidden power of trading activity: the FLB in tennis betting exchanges
(SAGE Publications, 2017) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Institute for Advanced Research in Business and Economics - INARBE
This paper examines the impact of trading activity on the Favourite-Longshot Bias (FLB) in tennis Betting Exchanges, using direct measures such as betting volume, average bet and standard deviation of the odds. According to predictions based on Disagreement Models, odds mispricing is positively associated with trading volume but negatively associated with the presence of institutional bettors. The FLB is also positively related to the degree of uncertainty in the market. The existence of two simultaneous markets (a “main” and an “alternative” market) in this specific sports-betting environment has enabled us to observe that the relative amount of attention given to the favourite versus that given to the long shot is positively associated with the FLB. Finally, information is more rapidly incorporated into the odds in the market that receives more attention from bettors, an effect that is intensified by the arbitrage and hedging that occurs between the two markets.

Can tax regulations moderate revenue diversification and reduce financial distress in nonprofit organizations?
(Wiley, 2022) Abinzano Guillén, María Isabel; López Arceiz, Francisco José; Zabaleta Arregui, Idoia; Economía; Ekonomia
As a result of policies to reduce public deficit, nonprofit organizations have been forced to turn to charitable donations in order to diversify their revenue structure and thus reduce their levels of financial distress. Public administrations have supported this process through tax mechanisms designed to provide a legal framework that will encourage private philanthropy. Our aim is to analyse the role of nonprofit tax regulations in moderating the influence of revenue diversification on insolvency risk. To this end, we drew a sample of 406 nonprofit organizations located in Aragon and Navarre, two European regions with different tax regulations, for the period 2008-2018. Our results reveal that some tax regime requirements, such as the organizational purpose, minimum initial endowment, engagement in commercial activity, and accountability and monitoring standards, have a positive impact on revenue diversification and the reduction of financial distress and vulnerability. However, we also detect differences between regions which suggest that tax harmonization for nonprofit organizations remains a challenge.

Does family ownership always reduce default risk?
(Wiley, 2021) Abinzano Guillén, María Isabel; Corredor Casado, María Pilar; Martínez García, Beatriz; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
This paper analyses the effect of family ownership on the outcome of the firm’s risk‐taking activities, measured by the company’s default risk. We show that family ownership reduces the probability of default, which is proxied by the Black–Scholes–Merton (BSM) model. Our study goes further than the initial approach by taking into account certain factors conditioning the aforementioned relationship. We find that the expected negative relationship between family ownership and default risk is modified when there is a significant participation of institutional investors, whose positive moderating influence intensifies if they are stable and long‐term oriented and/or during adverse financial circumstances.

The role of female directors in family firms' annual report's readability
(Emerald, 2024) Abinzano Guillén, María Isabel; Garcés Galdeano, Lucía; Martínez García, Beatriz; Gestión de Empresas; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE
Purpose: this paper investigates the impact of board gender diversity on the readability of the annual reports of family-controlled public companies. Design/methodology/approach: grounded in the premises of the restricted and extended views of the socioemotional wealth (SEW) approach and executive power theory, this paper explores the ways in which family-affiliated female directors influence report readability in a sample of 133 publicly traded US companies listed in the Fortune 1,000. We use the system GMM estimator, which deals with two key sources of endogeneity by controlling first for reverse causality, using the lags of the endogenous variables as instruments, and then for omitted variables, capturing the individual effect. Findings: our analysis confirms that the significant enhancement in annual report readability is associated with the presence of female family directors, particularly those who are insiders within the company. In contrast, non-family female directors and family outsider directors appear to have a negative impact on annual report readability. Originality/value: while scholars have increasingly focused on variations in annual report readability among family firms, the contribution of female directors to this phenomenon has received minimal attention. In our study, we integrate the theories of restricted and extended SEW perspectives with the theory of women's executive power within the board. This integration is essential for considering two critical factors: firstly, the primacy of their SEW objectives, and, secondly, their legitimacy within the board.

Dimensión económica y dimensión social de la empresa social: ¿cómo influye la concreción de los fines fundacionales?
(Universidad Complutense de Madrid, 2023) Abinzano Guillén, María Isabel; González Álvarez, Karen; Zabaleta Arregui, Idoia; Economía; Ekonomia; Gestión de Empresas; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE
Las empresas sociales fijan como objetivo primordial la consecución de impactos sociales garantizando al mismo tiempo la consecución de beneficios económicos y una adecuada gestión. Este enfoque tridimensional (económico, social y de gestión) puede ser adoptado por distintos tipos de organización. En concreto, las fundaciones pueden ser consideradas como empresas sociales en la medida en que desarrollen estas tres dimensiones. Sin embargo, la definición de un objetivo social podría afectar a la dimensión económica. La posibilidad de que emerjan tensiones entre la dimensión económica y social de estas organizaciones podría estar relacionada con la forma de definir el fin fundacional. No obstante, no existe hasta la fecha evidencia empírica que soporte esta afirmación. El objetivo de este estudio es examinar la relación que existe entre la concreción del fin fundacional, como expresión de la dimensión social de estas organizaciones, y el impacto en su viabilidad económica. Para ello, se cuenta con una muestra compuesta por fundaciones españolas ubicadas en dos regiones, Aragón y Navarra, que poseen regulaciones diferentes que afectan a la concreción del fin fundacional o misión social. Mediante el análisis de contenido, se evidencian notables diferencias en las fundaciones ubicadas en ambas regiones cuando se analiza la definición del fin fundacional y la dimensión económica.

Duty calls: prediction of failure in reorganization processes
(Emerald, 2023) Abinzano Guillén, María Isabel; Bonilla Acosta, Harold; Muga Caperos, Luis Fernando; Institute for Advanced Research in Business and Economics - INARBE
Purpose – Using data from business reorganization processes under Act 1116 of 2006 in Colombia during the period 2008 to 2018, a model for predicting the success of these processes is proposed. The paper aims to validate the model in two different periods. The first one, in 2019, characterized by stability, and the second one, in 2020, characterized by the uncertainty generated by the COVID-19 pandemic. Design/methodology/approach – A set of five financial variables comprising indebtedness, profitability and solvency proxies, firm age, macroeconomic conditions, and industry and regional dummies are used as independent variables in a logit model to predict the failure of reorganization processes. In addition, an out-ofsample analysis is carried out for the 2019 and 2020 periods. Findings – The results show a high predictive power of the estimated model. Even the results of the out-ofsample analysis are satisfactory during the unstable pandemic period. However, industry and regional effects add no predictive power for 2020, probably due to subsidies for economic activity and the relaxation of insolvency legislation in Colombia during that year. Originality/value – In a context of global reform in insolvency laws, the consistent predictive ability shown by the model, even during periods of uncertainty, can guide regulatory changes to ensure the survival of companies entering into reorganization processes, and reduce the observed high failure rate.

(AECA, 2021) Abinzano Guillén, María Isabel; López Arceiz, Francisco José; Zabaleta Arregui, Idoia; Gestión de Empresas; Enpresen Kudeaketa
El objetivo de este estudio es analizar el régimen fiscal especial para fundaciones contenido en la regulación tributaria de dos comunidades autónomas, Aragón y Navarra. En particular, se analizan los efectos de la regulación contenida en ambos regímenes sobre la estructura de ingresos de estas entidades. Para ello, se accedió a una muestra compuesta por 406 fundaciones durante el período 2008-2018. Nuestros resultados revelan que algunos aspectos de la regulación relacionados con el interés tutelado, la dotación inicial, el desarrollo de la actividad comercial y el nivel de rendición de cuentas favorecen una estructura de ingresos diversificada.

The effect of a switch of management company on pension plan fees
(Routledge, 2021) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
The impact of a switch of management company on pension plan fees is analysed by comparing the effects on employer-sponsored versus individual defined-contribution private pension plans in Spain. This framework is ideal because the two types differ significantly both in plan governance structure and consequently in the degree of bargaining power held by the decision-maker. In addition, intense bank restructuring, which has greatly modified the Spanish pension plan map, provides an interesting analytical context for the identification of causal links, because it is a scenario that features shocks exogenous to the relationship under analysis. The results show that a switch of management company significantly reduces management fees for employer-sponsored plans when the management change is not due to the bank restructuring process, on the contrary a switch of management company increases fees for individual pension plans.

Measuring credit risk in family firms
(SAGE, 2020) Abinzano Guillén, María Isabel; Corredor Casado, María Pilar; Martínez García, Beatriz; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
This article attempts to identify the default risk measure which best reflects the idiosyncratic context of public family firms. Seven accounting- and market-based measures are compared over a sample of 981 US family and non-family firms for the period 2000–2016. The results show that the Black–Scholes–Merton (BSM) measure gives the best fit in both types of firm. However, all the accounting-based measures, especially Altman’s Z-score, come closest to the market-based measures when used to assess the credit risk of family firms. The two types of measures also coincide more closely in their default risk orderings of family than of non-family firms. Useful practical implications can be drawn from these findings, which show that accounting-based measures can be used reliably in the absence of market data for family firms with similar characteristics to those in our sample.

Sports betting and the Black-Litterman model: a new portfolio-management perspective
(FiT Publishing, 2021) Abinzano Guillén, María Isabel; Campión Arrastia, María Jesús; Muga Caperos, Luis Fernando; Raventós Pujol, Armajac; Institute for Advanced Research in Business and Economics - INARBE
This paper transfers and adapts the Black-Litterman portfolio management model and its subsequent generalizations to the characteristics and specificities of assets quoted on sports betting markets. The results show that these assets are suitable for the application of portfolio management models with possible inclusion of investors' opinions. Information based on the variability of market prices and the attention received by NBA teams in Google Trends is successfully used to simulate the opinions expressed by a hypothetical portfolio manager. Furthermore, this makes these assets suitable for inclusion in portfolios in which managers are seeking returns uncorrelated with other assets.
