If the bitcoin market grows, size matters
(Taylor & Francis, 2021) Blasco de las Heras, Natividad; Corredor Casado, María Pilar; Gestión de Empresas; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE
This paper studies the herding behaviour among different exchanges trading bitcoin. The analysis allows us to conclude that the size of the exchange is an influencing parameter. Since 2018, when the significant growth in the number of exchanges became a reality, smaller exchanges have shown strong herding behaviour, whereas large exchanges seem to respond to their own information and beliefs and lead the process of price definition. This result may originate some temporary profitable strategies in the process of evolution towards efficiency according to the Adaptive Markets Hypothesis.

Can agents sensitive to cultural, organizational and environmental issues avoid herding?
(Elsevier, 2017) Blasco de las Heras, Natividad; Corredor Casado, María Pilar; Ferreruela Garcés, Sandra; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
Our findings indicate that herding behavior is affected not only by the cultural variables already discussed in the literature but also by other variables associated with organizational and environmental issues such as governance, technology, education and training, business style and conditions, and the development of equity and non-equity markets. Some of these act as catalysts, for example governance and technology. Others may have a corrective effect, such as the development of financial markets, business style, and education and training. If corrective factors are sufficiently developed, intentional herding practices could be reduced in the future.

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.

This paper aims to describe a teaching-learning experience based on ProjectBased Learning (PBL). This experience is part of an educational innovation project devoted to transforming finance classes in various facets of financial advice. Specifically, the article focuses on the transformation process of a subject that studies financial markets and the assets traded in them. Based on this experience, the classroom becomes a financial consulting firm that advises investors on how to invest their capital. The results show us a remarkable active dedication of the students to the course, improved knowledge, and marks. In addition, the development of skills and values such as teamwork, autonomy, solidarity, equality, and professional skills are elements that encourage us to continue along this line.

Is there an expiration effect in the bitcoin market?
(Elsevier, 2023) Blasco de las Heras, Natividad; Corredor Casado, María Pilar; Satrústegui, N.; Gestión de Empresas; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE
This paper studies the monthly expiration effect in the bitcoin markets. The emergence of trading in bitcoin futures in regulated markets is an ideal occasion to test this effect on an asset with singular characteristics. Our results with intraday data show that around the time of maturity there are significant changes in the trading volume, volatility and return of bitcoin, an asset that is traded in many exchanges simultaneously. Therefore, there is a clear expiration effect related to bitcoin futures. The closer to the expiration time (shortly beforehand or afterwards), the more intense these effects are. However, in spite of these general results, the expiration effect is not homogeneous across exchanges and depends on the characteristics of the futures contract in question. Robustness tests are also applied to confirm the results. The increasing participation of institutional investors is consistent with our findings, particularly in relation to the expiration effects of cash-settled futures, as these contracts are more appealing for sophisticated investors who could be interested in arbitrage or speculative processes.

Sovereign debt holdings and banks’ credit risk: evidence from the Eurozone
(Elsevier, 2021) Abinzano Guillén, María Isabel; Corredor Casado, María Pilar; Mansilla Fernández, José Manuel; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
This paper investigates the direct effect of sovereign debt holding on banks’ credit risk. Using individual Eurozone listed banks’ information, we find that holding sovereign debt improves the level of banks’ credit risk, but this effect is reversed when the credit risk associated with such debt is taken into account. For this purpose, we consider three alternative sovereign debt holding proxies and two types of banks’ credit-risk measures, both forward- and backward-looking. We find that the transmission of credit risk from sovereign debt holdings to banks’ credit risk is only captured when forward-looking credit-risk measures, based on market data, are used.

Does the betting industry price gender? Evidence from professional tennis
(SAGE Publications, 2021) Barrutiabengoa Ortubai, Joxe Maria; Corredor Casado, María Pilar; Muga Caperos, Luis Fernando; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
This research addresses the importance of gender in the pricing process of the sports betting industry. Specifically, we investigate the impact of gender in the prices that bookmakers offer for tennis matches. Despite widespread evidence of gender bias both in the practice of the sport and its media coverage, tennis is one of the sports that has done most to achieve equality. The analysis of 51,881 tennis matches reveals that betting firms quote higher prices for women's matches than for men's, even when considering uncertainty due to the surprise factor and the media attention. The separate analysis of two bookmakers strengthens the evidence for the role of media attention as a source of gender-related information asymmetry.

The role of sentiment and stock characteristics in the translation of analysts’ forecasts into recommendations
(Elsevier, 2019) Corredor Casado, María Pilar; Ferrer Zubiate, Elena; Santamaría Aquilué, Rafael; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
The purpose of this paper is to further understanding of the determinants of analysts’ translational effectiveness and, specifically, the role of stock characteristics in the impact of sentiment in the translation of analysts’ forecasts into recommendations. We construct a proxy of intrinsic value of a stock based on that of Ohlson (1995), which incorporates all the information contained in the analysts’ earnings forecasts. Our results show that, although analysts do translate their earnings forecast valuations into recommendations, the effectiveness of this process is reduced by investor sentiment only in highly sentiment-sensitive stocks. This suggests the degree of analyst coverage as a potential conditioner of the observable results in a market. While not totally eliminating this observed effect, the Market Abuse Directive regulation does contribute to reduce the skew between analysts’ earnings forecasts and their recommendations. Finally, analysis of this effect reveals that this kind of skew enables investment strategies yielding positive risk-adjusted returns in highly sentiment-sensitive stocks, during periods of high market sentiment.

The information environment, informed trading and volatility
(Routledge, 2017) Blasco de las Heras, Natividad; Corredor Casado, María Pilar; Gestión de Empresas; Enpresen Kudeaketa
The relation between informed trading and volatility is analyzed using the change in the proportion of informed transactions calculated through the probability of informed trading variable. The analysis relates to the Spanish market during 1997–2010, given that the Spanish market covers a very diverse range of listed companies. Some companies are comparable to companies listed on U.S. markets while others are smaller in size and have a lower trading volume and inferior quality of information. The methodology is based on a modification of the model proposed by Avramov, Chordia, and Goyal [2006]. The authors’ proposal incorporates the change in the proportion of informed transactions, calculated with intraday data, into the volatility model. The results are also presented using a conditional volatility model in which the change in the proportion of informed transactions is incorporated. These results attest to the influence of informed trading as a price-stabilizing factor in heavily traded and highly capitalized stocks (familiar stocks). Informed trading leads to a marked decrease in volatility for these particular stocks both in periods of calm and crisis.

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.
