    Abstract This article investigates whether COVID-19 pandemic had an effect on herding behaviour in Europe. Using a sample from the stock exchanges of France (Paris), Germany (Frankfurt), Italy (Milan), United Kingdom (London) and Spain (Madrid), over the period from January 03, 2000 to June 19, 2020, we found robust evidence that COVID-19 pandemic increased herding behaviour in the capital markets of Europe.

    Abstract The main objective of this research is to shed more light on how ESG may be seen as a valuable investment for family firms. We study the impact of ESG performance on the value of family firms by considering the moderating role played by financial constraints and agency costs. Using an international sample of 254 firms that belong to the 500 largest family-owned firms worldwide over the period 2015–2021, we report that the overall ESG score is positively associated with firm value. Among the three ESG components, we find that environmental and social performances have a positive and statistically significant impact on firm value. However, we find no evidence of any significant effect of governance score on firm value. More importantly, we also find that the impact of ESG performance on firm value is lower under the presence of financial constraints and agency costs.

    Abstract: Background: Inflammatory bowel disease (IBD) affects an estimated 1.6 million people in the United States with at least 70,000 new cases per year. In the last 15 years an increase in frequency of IBD cases from 0.30 cases per 100,000 person-years to 1 ... ...

    Abstract Background: Inflammatory bowel disease (IBD) affects an estimated 1.6 million people in the United States with at least 70,000 new cases per year. In the last 15 years an increase in frequency of IBD cases from 0.30 cases per 100,000 person-years to 1.83 cases per 100,000 person-years has been reported in Mexico. Variables such as early hospitalization at diagnosis, low hemoglobin levels, high values of C-reactive protein (CRP), fecal calprotectin concentration and absence of mucosal healing during evolution define the prognosis of these patients. However, the distance a patient must travel in order to reach a specialized treatment center can become an impediment for a correct diagnosis and treatment, severely impacting the clinical outcome of such patients.
    Methods: Observational, cross-sectional, retrospective study. Objective: In patients with IBD, determine the impact of distance between the residence and specialized treatment center on the general clinical outcome. Variables analyzed: sex, age, disease duration, average travel time, distance in kilometers between place of residence and specialized treatment center, Crohn´s Disease (CD) or Ulcerative Colitis (UC), and their respective severity classification scores, as well as number of hospital readmissions per year. The results were evaluated with ANOVA tests, univariate analysis had a 95% confidence index and a significant "p" determined as p < 0.05.
    Results: The study included 66 patients (45 UC and 21 CD). Mean age 51.15± 17.5 years. The distance between residence and hospital was calculated and classified into 3 quartiles based on proximity: 750km (quartile 3). There was a higher risk among patients in the most distant quartile for the use of biological therapy (OR, 2.20; 95% CI, 0.23- 20.55) and surgery (OR, 2.76, 95% CI 0.49- 15.48). We observed a clear relationship between the number of hospital readmission and the distance quartiles with a p = 0.0047.
    Conclusion: We observed an impact between the distance of residence and specialized treatment center over the patient's clinical outcome. More readmissions, greater disease activity scores, more use of biological therapy and surgery were observed in patients who had to travel more than 750km from their home to their specialized treatment center compared to the other travel quartiles, this with a p = 0.0047.

    Abstract Este artículo aplica seis técnicas y herramientas (análisis gráfico, gráfico de recurrencia, entropía de espacio temporal, coeficiente de Hurst, exponente de Lyapunov y dimensión de correlación), a las series de retornos del cobre, oro, petróleo, plata, zinc, aluminio, plomo y níquel, con el fin de corroborar la existencia de un comportamiento caótico en el mercado de commodities. Se encuentra evidencia de que los mercados financieros se comportan de forma caótica en contra de la hipótesis de aleatoriedad. Se contrasta, igualmente, no-normalidad, no-aleatoriedad y no-linealidad. Los resultados encontrados contradicen algunos de los supuestos básicos de la teoría financiera moderna.

    Abstract Este artículo investiga la relación entre estructura de propiedad y desempeño de 204 empresas chilenas para el período 1998-2007. Contrario a lo reportado por Demsetz (1983), Demsetz y Lehn (1985) y Demsetz y Villalonga (2001), la estructura de propiedad está relacionada con el desempeño de la firma. Los resultados del análisis econométrico muestran una relación negativa entre estructura de propiedad y desempeño, de carácter no lineal y estadísticamente significativa. En resumen, las empresas chilenas poseen una alta concentración de la propiedad que, aparentemente, es motivada por la posibilidad de extraer riqueza por parte del principal accionista.

    Abstract Este artículo evidencia un comportamiento caótico en las series de retornos de índices bursátiles latinoamericanos empleando Visual Recurrence Analysis. Utilizando la evolución diaria de los índices accionarios IPSA, MERVAL, BOVESPA e IPC, y luego de aplicar distintas técnicas y métodos como Análisis Gráfico, Análisis de Recurrencia y Entropía de Espacio Temporal, los resultados apoyan la hipótesis de que los mercados bursátiles latinoamericanos se comportan de forma caótica, en contra de la hipótesis de mercados eficientes. Esta conclusión valida el uso de herramientas predictivas de retornos accionarios en los mercados de renta variable latinoamericanos.
